text: The parabigeminal nucleus (PBG) is the mammalian homologue to the isthmic
complex of other vertebrates. Optogenetic stimulation of the PBG induces freezing
and escape in mice, a result thought to be caused by a PBG projection to the central
nucleus of the amygdala. However, the isthmic complex, including the PBG, has
been classically considered satellite nuclei of the Superior Colliculus (SC),
which upon stimulation of its medial part also triggers fear and avoidance reactions.
As the PBG-SC connectivity is not well characterized, we investigated whether
the topology of the PBG projection to the SC could be related to the behavioral
consequences of PBG stimulation. To that end, we performed immunohistochemistry,
in situ hybridization and neural tracer injections in the SC and PBG in a diurnal
rodent, the Octodon degus. We found that all PBG neurons expressed both glutamatergic
and cholinergic markers and were distributed in clearly defined anterior (aPBG)
and posterior (pPBG) subdivisions. The pPBG is connected reciprocally and topographically
to the ipsilateral SC, whereas the aPBG receives afferent axons from the ipsilateral
SC and projected exclusively to the contralateral SC. This contralateral projection
forms a dense field of terminals that is restricted to the medial SC, in correspondence
with the SC representation of the aerial binocular field which, we also found,
in O. degus prompted escape reactions upon looming stimulation. Therefore, this
specialized topography allows binocular interactions in the SC region controlling
responses to aerial predators, suggesting a link between the mechanisms by which
the SC and PBG produce defensive behaviors.

text: 'Epistasis, the context-dependence of the contribution of an amino acid substitution
to fitness, is common in evolution. To detect epistasis, fitness must be measured
for at least four genotypes: the reference genotype, two different single mutants
and a double mutant with both of the single mutations. For higher-order epistasis
of the order n, fitness has to be measured for all 2n genotypes of an n-dimensional
hypercube in genotype space forming a ‘combinatorially complete dataset’. So far,
only a handful of such datasets have been produced by manual curation. Concurrently,
random mutagenesis experiments have produced measurements of fitness and other
phenotypes in a high-throughput manner, potentially containing a number of combinatorially
complete datasets. We present an effective recursive algorithm for finding all
hypercube structures in random mutagenesis experimental data. To test the algorithm,
we applied it to the data from a recent HIS3 protein dataset and found all 199
847 053 unique combinatorially complete genotype combinations of dimensionality
ranging from 2 to 12. The algorithm may be useful for researchers looking for
higher-order epistasis in their high-throughput experimental data.'

text: Error analysis and data visualization of positive COVID-19 cases in 27 countries
have been performed up to August 8, 2020. This survey generally observes a progression
from early exponential growth transitioning to an intermediate power-law growth
phase, as recently suggested by Ziff and Ziff. The occurrence of logistic growth
after the power-law phase with lockdowns or social distancing may be described
as an effect of avoidance. A visualization of the power-law growth exponent over
short time windows is qualitatively similar to the Bhatia visualization for pandemic
progression. Visualizations like these can indicate the onset of second waves
and may influence social policy.

text: 'Extrasynaptic actions of glutamate are limited by high-affinity transporters
expressed by perisynaptic astroglial processes (PAPs): this helps maintain point-to-point
transmission in excitatory circuits. Memory formation in the brain is associated
with synaptic remodeling, but how this affects PAPs and therefore extrasynaptic
glutamate actions is poorly understood. Here, we used advanced imaging methods,
in situ and in vivo, to find that a classical synaptic memory mechanism, long-term
potentiation (LTP), triggers withdrawal of PAPs from potentiated synapses. Optical
glutamate sensors combined with patch-clamp and 3D molecular localization reveal
that LTP induction thus prompts spatial retreat of astroglial glutamate transporters,
boosting glutamate spillover and NMDA-receptor-mediated inter-synaptic cross-talk.
The LTP-triggered PAP withdrawal involves NKCC1 transporters and the actin-controlling
protein cofilin but does not depend on major Ca2+-dependent cascades in astrocytes.
We have therefore uncovered a mechanism by which a memory trace at one synapse
could alter signal handling by multiple neighboring connections.'

text: Nature creates electrons with two values of the spin projection quantum number.
In certain applications, it is important to filter electrons with one spin projection
from the rest. Such filtering is not trivial, since spin-dependent interactions
are often weak, and cannot lead to any substantial effect. Here we propose an
efficient spin filter based upon scattering from a two-dimensional crystal, which
is made of aligned point magnets. The polarization of the outgoing electron flux
is controlled by the crystal, and reaches maximum at specific values of the parameters.
In our scheme, polarization increase is accompanied by higher reflectivity of
the crystal. High transmission is feasible in scattering from a quantum cavity
made of two crystals. Our findings can be used for studies of low-energy spin-dependent
scattering from two-dimensional ordered structures made of magnetic atoms or aligned
chiral molecules.

text: Pancreatic islets play an essential role in regulating blood glucose level.
Although the molecular pathways underlying islet cell differentiation are beginning
to be resolved, the cellular basis of islet morphogenesis and fate allocation
remain unclear. By combining unbiased and targeted lineage tracing, we address
the events leading to islet formation in the mouse. From the statistical analysis
of clones induced at multiple embryonic timepoints, here we show that, during
the secondary transition, islet formation involves the aggregation of multiple
equipotent endocrine progenitors that transition from a phase of stochastic amplification
by cell division into a phase of sublineage restriction and limited islet fission.
Together, these results explain quantitatively the heterogeneous size distribution
and degree of polyclonality of maturing islets, as well as dispersion of progenitors
within and between islets. Further, our results show that, during the secondary
transition, α- and β-cells are generated in a contemporary manner. Together, these
findings provide insight into the cellular basis of islet development.

text: Cell fate transitions are key to development and homeostasis. It is thus essential
to understand the cellular mechanisms controlling fate transitions. Cell division
has been implicated in fate decisions in many stem cell types, including neuronal
and epithelial progenitors. In other stem cells, such as embryonic stem (ES) cells,
the role of division remains unclear. Here, we show that exit from naive pluripotency
in mouse ES cells generally occurs after a division. We further show that exit
timing is strongly correlated between sister cells, which remain connected by
cytoplasmic bridges long after division, and that bridge abscission progressively
accelerates as cells exit naive pluripotency. Finally, interfering with abscission
impairs naive pluripotency exit, and artificially inducing abscission accelerates
it. Altogether, our data indicate that a switch in the division machinery leading
to faster abscission regulates pluripotency exit. Our study identifies abscission
as a key cellular process coupling cell division to fate transitions.

text: In the computation of the material properties of random alloys, the method
of 'special quasirandom structures' attempts to approximate the properties of
the alloy on a finite volume with higher accuracy by replicating certain statistics
of the random atomic lattice in the finite volume as accurately as possible. In
the present work, we provide a rigorous justification for a variant of this method
in the framework of the Thomas–Fermi–von Weizsäcker (TFW) model. Our approach
is based on a recent analysis of a related variance reduction method in stochastic
homogenization of linear elliptic PDEs and the locality properties of the TFW
model. Concerning the latter, we extend an exponential locality result by Nazar
and Ortner to include point charges, a result that may be of independent interest.

text: Animal development entails the organization of specific cell types in space
and time, and spatial patterns must form in a robust manner. In the zebrafish
spinal cord, neural progenitors form stereotypic patterns despite noisy morphogen
signaling and large-scale cellular rearrangements during morphogenesis and growth.
By directly measuring adhesion forces and preferences for three types of endogenous
neural progenitors, we provide evidence for the differential adhesion model in
which differences in intercellular adhesion mediate cell sorting. Cell type–specific
combinatorial expression of different classes of cadherins (N-cadherin, cadherin
11, and protocadherin 19) results in homotypic preference ex vivo and patterning
robustness in vivo. Furthermore, the differential adhesion code is regulated by
the sonic hedgehog morphogen gradient. We propose that robust patterning during
tissue morphogenesis results from interplay between adhesion-based self-organization
and morphogen-directed patterning.

text: The α–z Rényi relative entropies are a two-parameter family of Rényi relative
entropies that are quantum generalizations of the classical α-Rényi relative entropies.
In the work [Adv. Math. 365, 107053 (2020)], we decided the full range of (α,
z) for which the data processing inequality (DPI) is valid. In this paper, we
give algebraic conditions for the equality in DPI. For the full range of parameters
(α, z), we give necessary conditions and sufficient conditions. For most parameters,
we give equivalent conditions. This generalizes and strengthens the results of
Leditzky et al. [Lett. Math. Phys. 107, 61–80 (2017)].

text: The brain represents and reasons probabilistically about complex stimuli and
motor actions using a noisy, spike-based neural code. A key building block for
such neural computations, as well as the basis for supervised and unsupervised
learning, is the ability to estimate the surprise or likelihood of incoming high-dimensional
neural activity patterns. Despite progress in statistical modeling of neural responses
and deep learning, current approaches either do not scale to large neural populations
or cannot be implemented using biologically realistic mechanisms. Inspired by
the sparse and random connectivity of real neuronal circuits, we present a model
for neural codes that accurately estimates the likelihood of individual spiking
patterns and has a straightforward, scalable, efficient, learnable, and realistic
neural implementation. This model’s performance on simultaneously recorded spiking
activity of >100 neurons in the monkey visual and prefrontal cortices is comparable
with or better than that of state-of-the-art models. Importantly, the model can
be learned using a small number of samples and using a local learning rule that
utilizes noise intrinsic to neural circuits. Slower, structural changes in random
connectivity, consistent with rewiring and pruning processes, further improve
the efficiency and sparseness of the resulting neural representations. Our results
merge insights from neuroanatomy, machine learning, and theoretical neuroscience
to suggest random sparse connectivity as a key design principle for neuronal computation.

text: Traditional robotic control suits require profound task-specific knowledge
for designing, building and testing control software. The rise of Deep Learning
has enabled end-to-end solutions to be learned entirely from data, requiring minimal
knowledge about the application area. We design a learning scheme to train end-to-end
linear dynamical systems (LDS)s by gradient descent in imitation learning robotic
domains. We introduce a new regularization loss component together with a learning
algorithm that improves the stability of the learned autonomous system, by forcing
the eigenvalues of the internal state updates of an LDS to be negative reals.
We evaluate our approach on a series of real-life and simulated robotic experiments,
in comparison to linear and nonlinear Recurrent Neural Network (RNN) architectures.
Our results show that our stabilizing method significantly improves test performance
of LDS, enabling such linear models to match the performance of contemporary nonlinear
RNN architectures. A video of the obstacle avoidance performance of our method
on a mobile robot, in unseen environments, compared to other methods can be viewed
at https://youtu.be/mhEsCoNao5E.

text: A binary neutron star merger has been observed in a multi-messenger detection
of gravitational wave (GW) and electromagnetic (EM) radiation. Binary neutron
stars that merge within a Hubble time, as well as many other compact binaries,
are expected to form via common envelope evolution. Yet five decades of research
on common envelope evolution have not yet resulted in a satisfactory understanding
of the multi-spatial multi-timescale evolution for the systems that lead to compact
binaries. In this paper, we report on the first successful simulations of common
envelope ejection leading to binary neutron star formation in 3D hydrodynamics.
We simulate the dynamical inspiral phase of the interaction between a 12M⊙ red
supergiant and a 1.4M⊙ neutron star for different initial separations and initial
conditions. For all of our simulations, we find complete envelope ejection and
final orbital separations of af≈1.3-5.1R⊙ depending on the simulation and criterion,
leading to binary neutron stars that can merge within a Hubble time. We find αCE-equivalent
efficiencies of ≈0.1-2.7 depending on the simulation and criterion, but this may
be specific for these extended progenitors. We fully resolve the core of the star
to ≲0.005R⊙ and our 3D hydrodynamics simulations are informed by an adjusted 1D
analytic energy formalism and a 2D kinematics study in order to overcome the prohibitive
computational cost of simulating these systems. The framework we develop in this
paper can be used to simulate a wide variety of interactions between stars, from
stellar mergers to common envelope episodes leading to GW sources.

text: In the high spin–orbit-coupled Sr2IrO4, the high sensitivity of the ground
state to the details of the local lattice structure shows a large potential for
the manipulation of the functional properties by inducing local lattice distortions.
We use epitaxial strain to modify the Ir–O bond geometry in Sr2IrO4 and perform
momentum-dependent resonant inelastic X-ray scattering (RIXS) at the metal and
at the ligand sites to unveil the response of the low-energy elementary excitations.
We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films
displays large softening along the [h,0] direction, while along the [h,h] direction
it shows hardening. This evolution reveals a renormalization of the magnetic interactions
caused by a strain-driven cross-over from anisotropic to isotropic interactions
between the magnetic moments. Moreover, we detect dispersive electron–hole pair
excitations which shift to lower (higher) energies upon compressive (tensile)
strain, manifesting a reduction (increase) in the size of the charge gap. This
behavior shows an intimate coupling between charge excitations and lattice distortions
in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals.
Our work highlights the central role played by the lattice degrees of freedom
in determining both the pseudospin and charge excitations of Sr2IrO4 and provides
valuable information toward the control of the ground state of complex oxides
in the presence of high spin–orbit coupling.

text: Mitochondrial complex I couples NADH:ubiquinone oxidoreduction to proton pumping
by an unknown mechanism. Here, we present cryo-electron microscopy structures
of ovine complex I in five different conditions, including turnover, at resolutions
up to 2.3 to 2.5 angstroms. Resolved water molecules allowed us to experimentally
define the proton translocation pathways. Quinone binds at three positions along
the quinone cavity, as does the inhibitor rotenone that also binds within subunit
ND4. Dramatic conformational changes around the quinone cavity couple the redox
reaction to proton translocation during open-to-closed state transitions of the
enzyme. In the induced deactive state, the open conformation is arrested by the
ND6 subunit. We propose a detailed molecular coupling mechanism of complex I,
which is an unexpected combination of conformational changes and electrostatic
interactions.

text: "Load imbalance pervasively exists in distributed deep learning training systems,
either caused by the inherent imbalance in learned tasks or by the system itself.
Traditional synchronous Stochastic Gradient Descent (SGD)\r\nachieves good accuracy
for a wide variety of tasks, but relies on global synchronization to accumulate
the gradients at every training step. In this paper, we propose eager-SGD, which
relaxes the global synchronization for\r\ndecentralized accumulation. To implement
eager-SGD, we propose to use two partial collectives: solo and majority. With
solo allreduce, the faster processes contribute their gradients eagerly without
waiting for the slower processes, whereas with majority allreduce, at least half
of the participants must contribute gradients before continuing, all without using
a central parameter server. We theoretically prove the convergence of the algorithms
and describe the partial collectives in detail. Experimental results on load-imbalanced
environments (CIFAR-10, ImageNet, and UCF101 datasets) show\r\nthat eager-SGD
achieves 1.27x speedup over the state-of-the-art synchronous SGD, without losing
accuracy."

text: Understanding the conformational sampling of translation-arrested ribosome
nascent chain complexes is key to understand co-translational folding. Up to now,
coupling of cysteine oxidation, disulfide bond formation and structure formation
in nascent chains has remained elusive. Here, we investigate the eye-lens protein
γB-crystallin in the ribosomal exit tunnel. Using mass spectrometry, theoretical
simulations, dynamic nuclear polarization-enhanced solid-state nuclear magnetic
resonance and cryo-electron microscopy, we show that thiol groups of cysteine
residues undergo S-glutathionylation and S-nitrosylation and form non-native disulfide
bonds. Thus, covalent modification chemistry occurs already prior to nascent chain
release as the ribosome exit tunnel provides sufficient space even for disulfide
bond formation which can guide protein folding.

text: Resources are rarely distributed uniformly within a population. Heterogeneity
in the concentration of a drug, the quality of breeding sites, or wealth can all
affect evolutionary dynamics. In this study, we represent a collection of properties
affecting the fitness at a given location using a color. A green node is rich
in resources while a red node is poorer. More colors can represent a broader spectrum
of resource qualities. For a population evolving according to the birth-death
Moran model, the first question we address is which structures, identified by
graph connectivity and graph coloring, are evolutionarily equivalent. We prove
that all properly two-colored, undirected, regular graphs are evolutionarily equivalent
(where “properly colored” means that no two neighbors have the same color). We
then compare the effects of background heterogeneity on properly two-colored graphs
to those with alternative schemes in which the colors are permuted. Finally, we
discuss dynamic coloring as a model for spatiotemporal resource fluctuations,
and we illustrate that random dynamic colorings often diminish the effects of
background heterogeneity relative to a proper two-coloring.

text: "Efficiently handling time-triggered and possibly nondeterministic switches\r\nfor
hybrid systems reachability is a challenging task. In this paper we present\r\nan
approach based on conservative set-based enclosure of the dynamics that can\r\nhandle
systems with uncertain parameters and inputs, where the uncertainties\r\nare bound
to given intervals. The method is evaluated on the plant model of an\r\nexperimental
electro-mechanical braking system with periodic controller. In\r\nthis model,
the fast-switching controller dynamics requires simulation time\r\nscales of the
order of nanoseconds. Accurate set-based computations for\r\nrelatively large
time horizons are known to be expensive. However, by\r\nappropriately decoupling
the time variable with respect to the spatial\r\nvariables, and enclosing the
uncertain parameters using interval matrix maps\r\nacting on zonotopes, we show
that the computation time can be lowered to 5000\r\ntimes faster with respect
to previous works. This is a step forward in formal\r\nverification of hybrid
systems because reduced run-times allow engineers to\r\nintroduce more expressiveness
in their models with a relatively inexpensive\r\ncomputational cost."

text: We consider various modeling levels for spatially homogeneous chemical reaction
systems, namely the chemical master equation, the chemical Langevin dynamics,
and the reaction-rate equation. Throughout we restrict our study to the case where
the microscopic system satisfies the detailed-balance condition. The latter allows
us to enrich the systems with a gradient structure, i.e. the evolution is given
by a gradient-flow equation. We present the arising links between the associated
gradient structures that are driven by the relative entropy of the detailed-balance
steady state. The limit of large volumes is studied in the sense of evolutionary
Γ-convergence of gradient flows. Moreover, we use the gradient structures to derive
hybrid models for coupling different modeling levels.

text: Breakdown of vascular barriers is a major complication of inflammatory diseases.
Anucleate platelets form blood-clots during thrombosis, but also play a crucial
role in inflammation. While spatio-temporal dynamics of clot formation are well
characterized, the cell-biological mechanisms of platelet recruitment to inflammatory
micro-environments remain incompletely understood. Here we identify Arp2/3-dependent
lamellipodia formation as a prominent morphological feature of immune-responsive
platelets. Platelets use lamellipodia to scan for fibrin(ogen) deposited on the
inflamed vasculature and to directionally spread, to polarize and to govern haptotactic
migration along gradients of the adhesive ligand. Platelet-specific abrogation
of Arp2/3 interferes with haptotactic repositioning of platelets to microlesions,
thus impairing vascular sealing and provoking inflammatory microbleeding. During
infection, haptotaxis promotes capture of bacteria and prevents hematogenic dissemination,
rendering platelets gate-keepers of the inflamed microvasculature. Consequently,
these findings identify haptotaxis as a key effector function of immune-responsive
platelets.

text: Cooperation is a ubiquitous and beneficial behavioural trait despite being
prone to exploitation by free-riders. Hence, cooperative populations are prone
to invasions by selfish individuals. However, a population consisting of only
free-riders typically does not survive. Thus, cooperators and free-riders often
coexist in some proportion. An evolutionary version of a Snowdrift Game proved
its efficiency in analysing this phenomenon. However, what if the system has already
reached its stable state but was perturbed due to a change in environmental conditions?
Then, individuals may have to re-learn their effective strategies. To address
this, we consider behavioural mistakes in strategic choice execution, which we
refer to as incompetence. Parametrising the propensity to make such mistakes allows
for a mathematical description of learning. We compare strategies based on their
relative strategic advantage relying on both fitness and learning factors. When
strategies are learned at distinct rates, allowing learning according to a prescribed
order is optimal. Interestingly, the strategy with the lowest strategic advantage
should be learnt first if we are to optimise fitness over the learning path. Then,
the differences between strategies are balanced out in order to minimise the effect
of behavioural uncertainty.

text: Reachability analysis aims at identifying states reachable by a system within
a given time horizon. This task is known to be computationally expensive for linear
hybrid systems. Reachability analysis works by iteratively applying continuous
and discrete post operators to compute states reachable according to continuous
and discrete dynamics, respectively. In this paper, we enhance both of these operators
and make sure that most of the involved computations are performed in low-dimensional
state space. In particular, we improve the continuous-post operator by performing
computations in high-dimensional state space only for time intervals relevant
for the subsequent application of the discrete-post operator. Furthermore, the
new discrete-post operator performs low-dimensional computations by leveraging
the structure of the guard and assignment of a considered transition. We illustrate
the potential of our approach on a number of challenging benchmarks.

text: 'Maintaining fertility in a fluctuating environment is key to the reproductive
success of flowering plants. Meiosis and pollen formation are particularly sensitive
to changes in growing conditions, especially temperature. We have previously identified
cyclin-dependent kinase G1 (CDKG1) as a master regulator of temperature-dependent
meiosis and this may involve the regulation of alternative splicing (AS), including
of its own transcript. CDKG1 mRNA can undergo several AS events, potentially producing
two protein variants: CDKG1L and CDKG1S, differing in their N-terminal domain
which may be involved in co-factor interaction. In leaves, both isoforms have
distinct temperature-dependent functions on target mRNA processing, but their
role in pollen development is unknown. In the present study, we characterize the
role of CDKG1L and CDKG1S in maintaining Arabidopsis fertility. We show that the
long (L) form is necessary and sufficient to rescue the fertility defects of the
cdkg1-1 mutant, while the short (S) form is unable to rescue fertility. On the
other hand, an extra copy of CDKG1L reduces fertility. In addition, mutation of
the ATP binding pocket of the kinase indicates that kinase activity is necessary
for the function of CDKG1. Kinase mutants of CDKG1L and CDKG1S correctly localize
to the cell nucleus and nucleus and cytoplasm, respectively, but are unable to
rescue either the fertility or the splicing defects of the cdkg1-1 mutant. Furthermore,
we show that there is partial functional overlap between CDKG1 and its paralog
CDKG2 that could in part be explained by overlapping gene expression.'

text: "Superconductor insulator transition in transverse magnetic field is studied
in the highly disordered MoC film with the product of the Fermi momentum and the
mean free path kF*l close to unity. Surprisingly, the Zeeman paramagnetic effects
dominate over orbital coupling on both sides of the transition. In superconducting
state it is evidenced by a high upper critical magnetic field \U0001D435\U0001D4502,
by its square root dependence on temperature, as well as by the Zeeman splitting
of the quasiparticle density of states (DOS) measured by scanning tunneling microscopy.
At \U0001D435\U0001D4502 a logarithmic anomaly in DOS is observed. This anomaly
is further enhanced in increasing magnetic field, which is explained by the Zeeman
splitting of the Altshuler-Aronov DOS driving\r\nthe system into a more insulating
or resistive state. Spin dependent Altshuler-Aronov correction is also needed
to explain the transport behavior above \U0001D435\U0001D4502."

text: Skeletal muscle activity is continuously modulated across physiologic states
to provide coordination, flexibility and responsiveness to body tasks and external
inputs. Despite the central role the muscular system plays in facilitating vital
body functions, the network of brain-muscle interactions required to control hundreds
of muscles and synchronize their activation in relation to distinct physiologic
states has not been investigated. Recent approaches have focused on general associations
between individual brain rhythms and muscle activation during movement tasks.
However, the specific forms of coupling, the functional network of cortico-muscular
coordination, and how network structure and dynamics are modulated by autonomic
regulation across physiologic states remains unknown. To identify and quantify
the cortico-muscular interaction network and uncover basic features of neuro-autonomic
control of muscle function, we investigate the coupling between synchronous bursts
in cortical rhythms and peripheral muscle activation during sleep and wake. Utilizing
the concept of time delay stability and a novel network physiology approach, we
find that the brain-muscle network exhibits complex dynamic patterns of communication
involving multiple brain rhythms across cortical locations and different electromyographic
frequency bands. Moreover, our results show that during each physiologic state
the cortico-muscular network is characterized by a specific profile of network
links strength, where particular brain rhythms play role of main mediators of
interaction and control. Further, we discover a hierarchical reorganization in
network structure across physiologic states, with high connectivity and network
link strength during wake, intermediate during REM and light sleep, and low during
deep sleep, a sleep-stage stratification that demonstrates a unique association
between physiologic states and cortico-muscular network structure. The reported
empirical observations are consistent across individual subjects, indicating universal
behavior in network structure and dynamics, and high sensitivity of cortico-muscular
control to changes in autonomic regulation, even at low levels of physical activity
and muscle tone during sleep. Our findings demonstrate previously unrecognized
basic principles of brain-muscle network communication and control, and provide
new perspectives on the regulatory mechanisms of brain dynamics and locomotor
activation, with potential clinical implications for neurodegenerative, movement
and sleep disorders, and for developing efficient treatment strategies.

text: Development of the nervous system undergoes important transitions,
including one from neurogenesis to gliogenesis which occurs late during embryonic
gestation. Here we report on clonal analysis of gliogenesis in mice using Mosaic
Analysis with Double Markers (MADM) with quantitative and computational methods.
Results reveal that developmental gliogenesis in the cerebral cortex occurs in
a fraction of earlier neurogenic clones, accelerating around E16.5, and giving
rise to both astrocytes and oligodendrocytes. Moreover, MADM-based genetic deletion
of the epidermal growth factor receptor (Egfr) in gliogenic clones revealed that
Egfr is cell autonomously required for gliogenesis in the mouse dorsolateral cortices.
A broad range in the proliferation capacity, symmetry of clones, and competitive
advantage of MADM cells was evident in clones that contained one cellular lineage
with double dosage of Egfr relative to their environment, while their sibling
Egfr-null cells failed to generate glia. Remarkably, the total numbers of glia
in MADM clones balance out regardless of significant alterations in clonal symmetries.
The variability in glial clones shows stochastic patterns that we define mathematically,
which are different from the deterministic patterns in neuronal clones. This study
sets a foundation for studying the biological significance of stochastic and deterministic
clonal principles underlying tissue development, and identifying mechanisms that
differentiate between neurogenesis and gliogenesis.

text: The actin-related protein (Arp)2/3 complex nucleates branched actin filament
networks pivotal for cell migration, endocytosis and pathogen infection. Its activation
is tightly regulated and involves complex structural rearrangements and actin
filament binding, which are yet to be understood. Here, we report a 9.0 Å resolution
structure of the actin filament Arp2/3 complex branch junction in cells using
cryo-electron tomography and subtomogram averaging. This allows us to generate
an accurate model of the active Arp2/3 complex in the branch junction and its
interaction with actin filaments. Notably, our model reveals a previously undescribed
set of interactions of the Arp2/3 complex with the mother filament, significantly
different to the previous branch junction model. Our structure also indicates
a central role for the ArpC3 subunit in stabilizing the active conformation.

text: "Currently several projects aim at designing and implementing protocols for
privacy preserving automated contact tracing to help fight the current pandemic.
Those proposal are quite similar, and in their most basic form basically propose
an app for mobile phones which broadcasts frequently changing pseudorandom identifiers
via (low energy) Bluetooth, and at the same time, the app stores IDs broadcast
by phones in its proximity. Only if a user is tested positive, they upload either
the beacons they did broadcast (which is the case in decentralized proposals as
DP-3T, east and west coast PACT or Covid watch) or received (as in Popp-PT or
ROBERT) during the last two weeks or so.\r\n\r\nVaudenay [eprint 2020/399] observes
that this basic scheme (he considers the DP-3T proposal) succumbs to relay and
even replay attacks, and proposes more complex interactive schemes which prevent
those attacks without giving up too many privacy aspects. Unfortunately interaction
is problematic for this application for efficiency and security reasons. The countermeasures
that have been suggested so far are either not practical or give up on key privacy
aspects. We propose a simple non-interactive variant of the basic protocol that\r\n(security)
Provably prevents replay and (if location data is available) relay attacks.\r\n(privacy)
The data of all parties (even jointly) reveals no information on the location
or time where encounters happened.\r\n(efficiency) The broadcasted message can
fit into 128 bits and uses only basic crypto (commitments and secret key authentication).\r\n\r\nTowards
this end we introduce the concept of “delayed authentication”, which basically
is a message authentication code where verification can be done in two steps,
where the first doesn’t require the key, and the second doesn’t require the message."

text: 'In prokaryotes, thermodynamic models of gene regulation provide a highly
quantitative mapping from promoter sequences to gene-expression levels that is
compatible with in vivo and in vitro biophysical measurements. Such concordance
has not been achieved for models of enhancer function in eukaryotes. In equilibrium
models, it is difficult to reconcile the reported short transcription factor (TF)
residence times on the DNA with the high specificity of regulation. In nonequilibrium
models, progress is difficult due to an explosion in the number of parameters.
Here, we navigate this complexity by looking for minimal nonequilibrium enhancer
models that yield desired regulatory phenotypes: low TF residence time, high specificity,
and tunable cooperativity. We find that a single extra parameter, interpretable
as the “linking rate,” by which bound TFs interact with Mediator components, enables
our models to escape equilibrium bounds and access optimal regulatory phenotypes,
while remaining consistent with the reported phenomenology and simple enough to
be inferred from upcoming experiments. We further find that high specificity in
nonequilibrium models is in a trade-off with gene-expression noise, predicting
bursty dynamics—an experimentally observed hallmark of eukaryotic transcription.
By drastically reducing the vast parameter space of nonequilibrium enhancer models
to a much smaller subspace that optimally realizes biological function, we deliver
a rich class of models that could be tractably inferred from data in the near
future.'

text: Quantum illumination uses entangled signal-idler photon pairs to boost the
detection efficiency of low-reflectivity objects in environments with bright thermal
noise. Its advantage is particularly evident at low signal powers, a promising
feature for applications such as noninvasive biomedical scanning or low-power
short-range radar. Here, we experimentally investigate the concept of quantum
illumination at microwave frequencies. We generate entangled fields to illuminate
a room-temperature object at a distance of 1 m in a free-space detection setup.
We implement a digital phase-conjugate receiver based on linear quadrature measurements
that outperforms a symmetric classical noise radar in the same conditions, despite
the entanglement-breaking signal path. Starting from experimental data, we also
simulate the case of perfect idler photon number detection, which results in a
quantum advantage compared with the relative classical benchmark. Our results
highlight the opportunities and challenges in the way toward a first room-temperature
application of microwave quantum circuits.

text: Quantum illumination is a sensing technique that employs entangled signal-idler
beams to improve the detection efficiency of low-reflectivity objects in environments
with large thermal noise. The advantage over classical strategies is evident at
low signal brightness, a feature which could make the protocol an ideal prototype
for non-invasive scanning or low-power short-range radar. Here we experimentally
investigate the concept of quantum illumination at microwave frequencies, by generating
entangled fields using a Josephson parametric converter which are then amplified
to illuminate a room-temperature object at a distance of 1 meter. Starting from
experimental data, we simulate the case of perfect idler photon number detection,
which results in a quantum advantage compared to the relative classical benchmark.
Our results highlight the opportunities and challenges on the way towards a first
room-temperature application of microwave quantum circuits.

text: "Microwave photonics lends the advantages of fiber optics to electronic sensing
and communication systems. In contrast to nonlinear optics, electro-optic devices
so far require classical modulation fields whose variance is dominated by electronic
or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional
single-sideband conversion of X band microwave to C band telecom light with a
microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of
less than or equal to 0.074 photons. This is facilitated by radiative cooling
and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures.
The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency
of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output
noise photons per second for the highest available pump power of 1.48 mW puts
near-unity efficiency pulsed quantum transduction within reach. Together with
the non-Gaussian resources of superconducting qubits this might provide the practical
foundation to extend the range and scope of current quantum networks in analogy
to electrical repeaters in classical fiber optic communication."

text: Quantum transduction, the process of converting quantum signals from one form
of energy to another, is an important area of quantum science and technology.
The present perspective article reviews quantum transduction between microwave
and optical photons, an area that has recently seen a lot of activity and progress
because of its relevance for connecting superconducting quantum processors over
long distances, among other applications. Our review covers the leading approaches
to achieving such transduction, with an emphasis on those based on atomic ensembles,
opto-electro-mechanics, and electro-optics. We briefly discuss relevant metrics
from the point of view of different applications, as well as challenges for the
future.

text: We give a short and self-contained proof for rates of convergence of the Allen--Cahn
equation towards mean curvature flow, assuming that a classical (smooth) solution
to the latter exists and starting from well-prepared initial data. Our approach
is based on a relative entropy technique. In particular, it does not require a
stability analysis for the linearized Allen--Cahn operator. As our analysis also
does not rely on the comparison principle, we expect it to be applicable to more
complex equations and systems.

text: We consider the free additive convolution of two probability measures μ and
ν on the real line and show that μ ⊞ v is supported on a single interval if μ
and ν each has single interval support. Moreover, the density of μ ⊞ ν is proven
to vanish as a square root near the edges of its support if both μ and ν have
power law behavior with exponents between −1 and 1 near their edges. In particular,
these results show the ubiquity of the conditions in our recent work on optimal
local law at the spectral edges for addition of random matrices [5].

text: Quantum information technology based on solid state qubits has created much
interest in converting quantum states from the microwave to the optical domain.
Optical photons, unlike microwave photons, can be transmitted by fiber, making
them suitable for long distance quantum communication. Moreover, the optical domain
offers access to a large set of very well‐developed quantum optical tools, such
as highly efficient single‐photon detectors and long‐lived quantum memories. For
a high fidelity microwave to optical transducer, efficient conversion at single
photon level and low added noise is needed. Currently, the most promising approaches
to build such systems are based on second‐order nonlinear phenomena such as optomechanical
and electro‐optic interactions. Alternative approaches, although not yet as efficient,
include magneto‐optical coupling and schemes based on isolated quantum systems
like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations
for the most important microwave‐to‐optical conversion experiments are provided,
their implementations are described, and the current limitations and future prospects
are discussed.

text: "Distributed ledgers provide high availability and integrity, making them
a key enabler for practical and secure computation of distributed workloads among
mutually distrustful parties. Many practical applications also require strong
confidentiality, however. This work enhances permissioned and permissionless blockchains
with the ability to manage confidential data without forfeiting availability or
decentralization. The proposed Calypso architecture addresses two orthogonal challenges
confronting modern distributed ledgers: (a) enabling the auditable management
of secrets and (b) protecting distributed computations against arbitrage attacks
when their results depend on the ordering and secrecy of inputs.\r\n\r\nCalypso
introduces on-chain secrets, a novel abstraction that enforces atomic deposition
of an auditable trace whenever users access confidential data. Calypso provides
user-controlled consent management that ensures revocation atomicity and accountable
anonymity. To enable permissionless deployment, we introduce an incentive scheme
and provide users with the option to select their preferred trustees. We evaluated
our Calypso prototype with a confidential document-sharing application and a decentralized
lottery. Our benchmarks show that transaction-processing latency increases linearly
in terms of security (number of trustees) and is in the range of 0.2 to 8 seconds
for 16 to 128 trustees."

text: 'Many-body localization provides a mechanism to avoid thermalization in isolated
interacting quantum systems. The breakdown of thermalization may be complete,
when all eigenstates in the many-body spectrum become localized, or partial, when
the so-called many-body mobility edge separates localized and delocalized parts
of the spectrum. Previously, De Roeck et al. [Phys. Rev. B 93, 014203 (2016)]
suggested a possible instability of the many-body mobility edge in energy density.
The local ergodic regions—so-called “bubbles”—resonantly spread throughout the
system, leading to delocalization. In order to study such instability mechanism,
in this work we design a model featuring many-body mobility edge in particle density:
the states at small particle density are localized, while increasing the density
of particles leads to delocalization. Using numerical simulations with matrix
product states, we demonstrate the stability of many-body localization with respect
to small bubbles in large dilute systems for experimentally relevant timescales.
In addition, we demonstrate that processes where the bubble spreads are favored
over processes that lead to resonant tunneling, suggesting a possible mechanism
behind the observed stability of many-body mobility edge. We conclude by proposing
experiments to probe particle density mobility edge in the Bose-Hubbard model.'

text: We consider the sum of two large Hermitian matrices A and B with a Haar unitary
conjugation bringing them into a general relative position. We prove that the
eigenvalue density on the scale slightly above the local eigenvalue spacing is
asymptotically given by the free additive convolution of the laws of A and B as
the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues
and optimal rate of convergence in Voiculescu's theorem. Our previous works [4],
[5] established these results in the bulk spectrum, the current paper completely
settles the problem at the spectral edges provided they have the typical square-root
behavior. The key element of our proof is to compensate the deterioration of the
stability of the subordination equations by sharp error estimates that properly
account for the local density near the edge. Our results also hold if the Haar
unitary matrix is replaced by the Haar orthogonal matrix.

text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: We prove a central limit theorem for the difference of linear eigenvalue statistics
of a sample covariance matrix W˜ and its minor W. We find that the fluctuation
of this difference is much smaller than those of the individual linear statistics,
as a consequence of the strong correlation between the eigenvalues of W˜ and W.
Our result identifies the fluctuation of the spatial derivative of the approximate
Gaussian field in the recent paper by Dumitru and Paquette. Unlike in a similar
result for Wigner matrices, for sample covariance matrices, the fluctuation may
entirely vanish.

text: "Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed
tremendously, mostly because of their exceptional optoelectronic properties. Core@shell
NCs, in which one or more inorganic layers overcoat individual NCs, recently received
significant attention due to their remarkable optical characteristics. Reduced
Auger recombination, suppressed blinking, and enhanced carrier multiplication
are among the merits of core@shell NCs. Despite their importance in device development,
the influence of the shell and the surface modification of the core@shell NC assemblies
on the charge carrier transport remains a pertinent research objective. Type-II
PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated,
still exhibit instability of their electron \r\n ransport. Here, we demonstrate
the enhancement of electron transport and stability in PbTe@PbS core@shell NC
assemblies using iodide as a surface passivating ligand. The combination of the
PbS shelling and the use of the iodide ligand contributes to the addition of one
mobile electron for each core@shell NC. Furthermore, both electron mobility and
on/off current modulation ratio values of the core@shell NC field-effect transistor
are steady with the usage of iodide. Excellent stability in these exclusively
electron-transporting core@shell NCs paves the way for their utilization in electronic
devices. "

text: The goal of limiting global warming to 1.5 °C requires a drastic reduction
in CO2 emissions across many sectors of the world economy. Batteries are vital
to this endeavor, whether used in electric vehicles, to store renewable electricity,
or in aviation. Present lithium-ion technologies are preparing the public for
this inevitable change, but their maximum theoretical specific capacity presents
a limitation. Their high cost is another concern for commercial viability. Metal–air
batteries have the highest theoretical energy density of all possible secondary
battery technologies and could yield step changes in energy storage, if their
practical difficulties could be overcome. The scope of this review is to provide
an objective, comprehensive, and authoritative assessment of the intensive work
invested in nonaqueous rechargeable metal–air batteries over the past few years,
which identified the key problems and guides directions to solve them. We focus
primarily on the challenges and outlook for Li–O2 cells but include Na–O2, K–O2,
and Mg–O2 cells for comparison. Our review highlights the interdisciplinary nature
of this field that involves a combination of materials chemistry, electrochemistry,
computation, microscopy, spectroscopy, and surface science. The mechanisms of
O2 reduction and evolution are considered in the light of recent findings, along
with developments in positive and negative electrodes, electrolytes, electrocatalysis
on surfaces and in solution, and the degradative effect of singlet oxygen, which
is typically formed in Li–O2 cells.

text: Spontaneously arising channels that transport the phytohormone auxin provide
positional cues for self-organizing aspects of plant development such as flexible
vasculature regeneration or its patterning during leaf venation. The auxin canalization
hypothesis proposes a feedback between auxin signaling and transport as the underlying
mechanism, but molecular players await discovery. We identified part of the machinery
that routes auxin transport. The auxin-regulated receptor CAMEL (Canalization-related
Auxin-regulated Malectin-type RLK) together with CANAR (Canalization-related Receptor-like
kinase) interact with and phosphorylate PIN auxin transporters. camel and canar
mutants are impaired in PIN1 subcellular trafficking and auxin-mediated PIN polarization,
which macroscopically manifests as defects in leaf venation and vasculature regeneration
after wounding. The CAMEL-CANAR receptor complex is part of the auxin feedback
that coordinates polarization of individual cells during auxin canalization.

text: Organic materials are known to feature long spin-diffusion times, originating
in a generally small spin–orbit coupling observed in these systems. From that
perspective, chiral molecules acting as efficient spin selectors pose a puzzle
that attracted a lot of attention in recent years. Here, we revisit the physical
origins of chiral-induced spin selectivity (CISS) and propose a simple analytic
minimal model to describe it. The model treats a chiral molecule as an anisotropic
wire with molecular dipole moments aligned arbitrarily with respect to the wire’s
axes and is therefore quite general. Importantly, it shows that the helical structure
of the molecule is not necessary to observe CISS and other chiral nonhelical molecules
can also be considered as potential candidates for the CISS effect. We also show
that the suggested simple model captures the main characteristics of CISS observed
in the experiment, without the need for additional constraints employed in the
previous studies. The results pave the way for understanding other related physical
phenomena where the CISS effect plays an essential role.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

text: Dipolar (or spatially indirect) excitons (IXs) in semiconductor double quantum
well (DQW) subjected to an electric field are neutral species with a dipole moment
oriented perpendicular to the DQW plane. Here, we theoretically study interactions
between IXs in stacked DQW bilayers, where the dipolar coupling can be either
attractive or repulsive depending on the relative positions of the particles.
By using microscopic band structure calculations to determine the electronic states
forming the excitons, we show that the attractive dipolar interaction between
stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW
interaction energy and making the IX even more electrically polarizable. Many-particle
interaction effects are addressed by considering the coupling between a single
IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either
as a closed-packed lattice or as a continuum IX fluid. We find that the lattice
model yields IX interlayer binding energies decreasing with increasing lattice
density. This behavior is due to the dominating role of the intra-DQW dipolar
repulsion, which prevents more than one exciton from entering the attractive region
of the inter-DQW coupling. Finally, both models shows that the single IX distorts
the distribution of IXs in the adjacent DQW, thus inducing the formation of an
IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with
IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous
dependence on density in semiquantitative agreement with a recent experimental
study [cf. Hubert et al., Phys. Rev. X 9, 021026 (2019)].

text: One of the hallmarks of quantum statistics, tightly entwined with the concept
of topological phases of matter, is the prediction of anyons. Although anyons
are predicted to be realized in certain fractional quantum Hall systems, they
have not yet been unambiguously detected in experiment. Here we introduce a simple
quantum impurity model, where bosonic or fermionic impurities turn into anyons
as a consequence of their interaction with the surrounding many-particle bath.
A cloud of phonons dresses each impurity in such a way that it effectively attaches
fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding
quantum impurity model, first, provides a different approach to the numerical
solution of the many-anyon problem, along with a concrete perspective of anyons
as emergent quasiparticles built from composite bosons or fermions. More importantly,
the model paves the way toward realizing anyons using impurities in crystal lattices
as well as ultracold gases. In particular, we consider two heavy electrons interacting
with a two-dimensional lattice crystal in a magnetic field, and show that when
the impurity-bath system is rotated at the cyclotron frequency, impurities behave
as anyons as a consequence of the angular momentum exchange between the impurities
and the bath. A possible experimental realization is proposed by identifying the
statistics parameter in terms of the mean-square distance of the impurities and
the magnetization of the impurity-bath system, both of which are accessible to
experiment. Another proposed application is impurities immersed in a two-dimensional
weakly interacting Bose gas.

text: Multilayer graphene lattices allow for an additional tunability of the band
structure by the strong perpendicular electric field. In particular, the emergence
of the new multiple Dirac points in ABA stacked trilayer graphene subject to strong
transverse electric fields was proposed theoretically and confirmed experimentally.
These new Dirac points dubbed “gullies” emerge from the interplay between strong
electric field and trigonal warping. In this work, we first characterize the properties
of new emergent Dirac points and show that the electric field can be used to tune
the distance between gullies in the momentum space. We demonstrate that the band
structure has multiple Lifshitz transitions and higher-order singularity of “monkey
saddle” type. Following the characterization of the band structure, we consider
the spectrum of Landau levels and structure of their wave functions. In the limit
of strong electric fields when gullies are well separated in momentum space, they
give rise to triply degenerate Landau levels. In the second part of this work,
we investigate how degeneracy between three gully Landau levels is lifted in the
presence of interactions. Within the Hartree-Fock approximation we show that the
symmetry breaking state interpolates between the fully gully polarized state that
breaks C3 symmetry at high displacement field and the gully symmetric state when
the electric field is decreased. The discontinuous transition between these two
states is driven by enhanced intergully tunneling and exchange. We conclude by
outlining specific experimental predictions for the existence of such a symmetry-breaking
state.

text: In laboratory studies and numerical simulations, we observe clear signatures
of unstable time-periodic solutions in a moderately turbulent quasi-two-dimensional
flow. We validate the dynamical relevance of such solutions by demonstrating that
turbulent flows in both experiment and numerics transiently display time-periodic
dynamics when they shadow unstable periodic orbits (UPOs). We show that UPOs we
computed are also statistically significant, with turbulent flows spending a sizable
fraction of the total time near these solutions. As a result, the average rates
of energy input and dissipation for the turbulent flow and frequently visited
UPOs differ only by a few percent.

text: Peptides derived from non-functional precursors play important roles in various
developmental processes, but also in (a)biotic stress signaling. Our (phospho)proteome-wide
analyses of C-terminally encoded peptide 5 (CEP5)-mediated changes revealed an
impact on abiotic stress-related processes. Drought has a dramatic impact on plant
growth, development and reproduction, and the plant hormone auxin plays a role
in drought responses. Our genetic, physiological, biochemical and pharmacological
results demonstrated that CEP5-mediated signaling is relevant for osmotic and
drought stress tolerance in Arabidopsis, and that CEP5 specifically counteracts
auxin effects. Specifically, we found that CEP5 signaling stabilizes AUX/IAA transcriptional
repressors, suggesting the existence of a novel peptide-dependent control mechanism
that tunes auxin signaling. These observations align with the recently described
role of AUX/IAAs in stress tolerance and provide a novel role for CEP5 in osmotic
and drought stress tolerance.

text: Cell polarity is a fundamental feature of all multicellular organisms. In
plants, prominent cell polarity markers are PIN auxin transporters crucial for
plant development. To identify novel components involved in cell polarity establishment
and maintenance, we carried out a forward genetic screening with PIN2:PIN1-HA;pin2
Arabidopsis plants, which ectopically express predominantly basally localized
PIN1 in the root epidermal cells leading to agravitropic root growth. From the
screen, we identified the regulator of PIN polarity 12 (repp12) mutation, which
restored gravitropic root growth and caused PIN1-HA polarity switch from basal
to apical side of root epidermal cells. Complementation experiments established
the repp12 causative mutation as an amino acid substitution in Aminophospholipid
ATPase3 (ALA3), a phospholipid flippase with predicted function in vesicle formation.
ala3 T-DNA mutants show defects in many auxin-regulated processes, in asymmetric
auxin distribution and in PIN trafficking. Analysis of quintuple and sextuple
mutants confirmed a crucial role of ALA proteins in regulating plant development
and in PIN trafficking and polarity. Genetic and physical interaction studies
revealed that ALA3 functions together with GNOM and BIG3 ARF GEFs. Taken together,
our results identified ALA3 flippase as an important interactor and regulator
of ARF GEF functioning in PIN polarity, trafficking and auxin-mediated development.

text: Clathrin-mediated endocytosis (CME) and its core endocytic machinery are evolutionarily
conserved across all eukaryotes. In mammals, the heterotetrameric adaptor protein
complex-2 (AP-2) sorts plasma membrane (PM) cargoes into vesicles through the
recognition of motifs based on tyrosine or di-leucine in their cytoplasmic tails.
However, in plants, very little is known on how PM proteins are sorted for CME
and whether similar motifs are required. In Arabidopsis thaliana, the brassinosteroid
(BR) receptor, BR INSENSITIVE1 (BRI1), undergoes endocytosis that depends on clathrin
and AP-2. Here we demonstrate that BRI1 binds directly to the medium AP-2 subunit,
AP2M. The cytoplasmic domain of BRI1 contains five putative canonical surface-exposed
tyrosine-based endocytic motifs. The tyrosine-to-phenylalanine substitution in
Y898KAI reduced BRI1 internalization without affecting its kinase activity. Consistently,
plants carrying the BRI1Y898F mutation were hypersensitive to BRs. Our study demonstrates
that AP-2-dependent internalization of PM proteins via the recognition of functional
tyrosine motifs also operates in plants.

text: The TPLATE complex (TPC) is a key endocytic adaptor protein complex in plants.
TPC in Arabidopsis (Arabidopsis thaliana) contains six evolutionarily conserved
subunits and two plant-specific subunits, AtEH1/Pan1 and AtEH2/Pan1, although
cytoplasmic proteins are not associated with the hexameric subcomplex in the cytoplasm.
To investigate the dynamic assembly of the octameric TPC at the plasma membrane
(PM), we performed state-of-the-art dual-color live cell imaging at physiological
and lowered temperatures. Lowering the temperature slowed down endocytosis, thereby
enhancing the temporal resolution of the differential recruitment of endocytic
components. Under both normal and lowered temperature conditions, the core TPC
subunit TPLATE and the AtEH/Pan1 proteins exhibited simultaneous recruitment at
the PM. These results, together with co-localization analysis of different TPC
subunits, allow us to conclude that TPC in plant cells is not recruited to the
PM sequentially but as an octameric complex.

text: Cell production and differentiation for the acquisition of specific functions
are key features of living systems. The dynamic network of cellular microtubules
provides the necessary platform to accommodate processes associated with the transition
of cells through the individual phases of cytogenesis. Here, we show that the
plant hormone cytokinin fine‐tunes the activity of the microtubular cytoskeleton
during cell differentiation and counteracts microtubular rearrangements driven
by the hormone auxin. The endogenous upward gradient of cytokinin activity along
the longitudinal growth axis in Arabidopsis thaliana roots correlates with robust
rearrangements of the microtubule cytoskeleton in epidermal cells progressing
from the proliferative to the differentiation stage. Controlled increases in cytokinin
activity result in premature re‐organization of the microtubule network from transversal
to an oblique disposition in cells prior to their differentiation, whereas attenuated
hormone perception delays cytoskeleton conversion into a configuration typical
for differentiated cells. Intriguingly, cytokinin can interfere with microtubules
also in animal cells, such as leukocytes, suggesting that a cytokinin‐sensitive
control pathway for the microtubular cytoskeleton may be at least partially conserved
between plant and animal cells.

text: Origin and functions of intermittent transitions among sleep stages, including
brief awakenings and arousals, constitute a challenge to the current homeostatic
framework for sleep regulation, focusing on factors modulating sleep over large
time scales. Here we propose that the complex micro-architecture characterizing
sleep on scales of seconds and minutes results from intrinsic non-equilibrium
critical dynamics. We investigate θ- and δ-wave dynamics in control rats and in
rats where the sleep-promoting ventrolateral preoptic nucleus (VLPO) is lesioned
(male Sprague-Dawley rats). We demonstrate that bursts in θ and δ cortical rhythms
exhibit complex temporal organization, with long-range correlations and robust
duality of power-law (θ-bursts, active phase) and exponential-like (δ-bursts,
quiescent phase) duration distributions, features typical of non-equilibrium systems
self-organizing at criticality. We show that such non-equilibrium behavior relates
to anti-correlated coupling between θ- and δ-bursts, persists across a range of
time scales, and is independent of the dominant physiologic state; indications
of a basic principle in sleep regulation. Further, we find that VLPO lesions lead
to a modulation of cortical dynamics resulting in altered dynamical parameters
of θ- and δ-bursts and significant reduction in θ–δ coupling. Our empirical findings
and model simulations demonstrate that θ–δ coupling is essential for the emerging
non-equilibrium critical dynamics observed across the sleep–wake cycle, and indicate
that VLPO neurons may have dual role for both sleep and arousal/brief wake activation.
The uncovered critical behavior in sleep- and wake-related cortical rhythms indicates
a mechanism essential for the micro-architecture of spontaneous sleep-stage and
arousal transitions within a novel, non-homeostatic paradigm of sleep regulation.

text: We consider a dilute, homogeneous Bose gas at positive temperature. The system
is investigated in the Gross–Pitaevskii limit, where the scattering length a is
so small that the interaction energy is of the same order of magnitude as the
spectral gap of the Laplacian, and for temperatures that are comparable to the
critical temperature of the ideal gas. We show that the difference between the
specific free energy of the interacting system and the one of the ideal gas is
to leading order given by 4πa(2ϱ2−ϱ20). Here ϱ denotes the density of the system
and ϱ0 is the expected condensate density of the ideal gas. Additionally, we show
that the one-particle density matrix of any approximate minimizer of the Gibbs
free energy functional is to leading order given by the one of the ideal gas.
This in particular proves Bose–Einstein condensation with critical temperature
given by the one of the ideal gas to leading order. One key ingredient of our
proof is a novel use of the Gibbs variational principle that goes hand in hand
with the c-number substitution.

text: We study the dynamics of a system of N interacting bosons in a disc-shaped
trap, which is realised by an external potential that confines the bosons in one
spatial dimension to an interval of length of order ε. The interaction is non-negative
and scaled in such a way that its scattering length is of order ε/N, while its
range is proportional to (ε/N)β with scaling parameter β∈(0,1]. We consider the
simultaneous limit (N,ε)→(∞,0) and assume that the system initially exhibits Bose–Einstein
condensation. We prove that condensation is preserved by the N-body dynamics,
where the time-evolved condensate wave function is the solution of a two-dimensional
non-linear equation. The strength of the non-linearity depends on the scaling
parameter β. For β∈(0,1), we obtain a cubic defocusing non-linear Schrödinger
equation, while the choice β=1 yields a Gross–Pitaevskii equation featuring the
scattering length of the interaction. In both cases, the coupling parameter depends
on the confining potential.

text: "For 1≤m≤n, we consider a natural m-out-of-n multi-instance scenario for a
public-key encryption (PKE) scheme. An adversary, given n independent instances
of PKE, wins if he breaks at least m out of the n instances. In this work, we
are interested in the scaling factor of PKE schemes, SF, which measures how well
the difficulty of breaking m out of the n instances scales in m. That is, a scaling
factor SF=ℓ indicates that breaking m out of n instances is at least ℓ times more
difficult than breaking one single instance. A PKE scheme with small scaling factor
hence provides an ideal target for mass surveillance. In fact, the Logjam attack
(CCS 2015) implicitly exploited, among other things, an almost constant scaling
factor of ElGamal over finite fields (with shared group parameters).\r\n\r\nFor
Hashed ElGamal over elliptic curves, we use the generic group model to argue that
the scaling factor depends on the scheme's granularity. In low granularity, meaning
each public key contains its independent group parameter, the scheme has optimal
scaling factor SF=m; In medium and high granularity, meaning all public keys share
the same group parameter, the scheme still has a reasonable scaling factor SF=√m.
Our findings underline that instantiating ElGamal over elliptic curves should
be preferred to finite fields in a multi-instance scenario.\r\n\r\nAs our main
technical contribution, we derive new generic-group lower bounds of Ω(√(mp)) on
the difficulty of solving both the m-out-of-n Gap Discrete Logarithm and the m-out-of-n
Gap Computational Diffie-Hellman problem over groups of prime order p, extending
a recent result by Yun (EUROCRYPT 2015). We establish the lower bound by studying
the hardness of a related computational problem which we call the search-by-hypersurface
problem."

text: We introduce the monitoring of trace properties under assumptions. An assumption
limits the space of possible traces that the monitor may encounter. An assumption
may result from knowledge about the system that is being monitored, about the
environment, or about another, connected monitor. We define monitorability under
assumptions and study its theoretical properties. In particular, we show that
for every assumption A, the boolean combinations of properties that are safe or
co-safe relative to A are monitorable under A. We give several examples and constructions
on how an assumption can make a non-monitorable property monitorable, and how
an assumption can make a monitorable property monitorable with fewer resources,
such as integer registers.

text: "We introduce the notion of Witness Maps as a cryptographic notion of a proof
system. A Unique Witness Map (UWM) deterministically maps all witnesses for an
\ NP statement to a single representative witness, resulting in a computationally
sound, deterministic-prover, non-interactive witness independent proof system.
A relaxation of UWM, called Compact Witness Map (CWM), maps all the witnesses
to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive
proof-system. We also define a Dual Mode Witness Map (DMWM) which adds an “extractable”
mode to a CWM.\r\nOur main construction is a DMWM for all NP relations, assuming
sub-exponentially secure indistinguishability obfuscation ( iO ), along with
standard cryptographic assumptions. The DMWM construction relies on a CWM and
a new primitive called Cumulative All-Lossy-But-One Trapdoor Functions (C-ALBO-TDF),
both of which are in turn instantiated based on iO and other primitives. Our
instantiation of a CWM is in fact a UWM; in turn, we show that a UWM implies Witness
Encryption. Along the way to constructing UWM and C-ALBO-TDF, we also construct,
from standard assumptions, Puncturable Digital Signatures and a new primitive
called Cumulative Lossy Trapdoor Functions (C-LTDF). The former improves up on
a construction of Bellare et al. (Eurocrypt 2016), who relied on sub-exponentially
secure iO and sub-exponentially secure OWF.\r\nAs an application of our constructions,
we show how to use a DMWM to construct the first leakage and tamper-resilient
signatures with a deterministic signer, thereby solving a decade old open problem
posed by Katz and Vaikunthanathan (Asiacrypt 2009), by Boyle, Segev and Wichs
(Eurocrypt 2011), as well as by Faonio and Venturi (Asiacrypt 2016). Our construction
achieves the optimal leakage rate of 1−o(1) ."

text: We consider a system of N bosons in the limit N→∞, interacting through singular
potentials. For initial data exhibiting Bose–Einstein condensation, the many-body
time evolution is well approximated through a quadratic fluctuation dynamics around
a cubic nonlinear Schrödinger equation of the condensate wave function. We show
that these fluctuations satisfy a (multi-variate) central limit theorem.

text: The biotic interactions hypothesis posits that biotic interactions are more
important drivers of adaptation closer to the equator, evidenced by “stronger”
contemporary interactions (e.g. greater interaction rates) and/or patterns of
trait evolution consistent with a history of stronger interactions. Support for
the hypothesis is mixed, but few studies span tropical and temperate regions while
experimentally controlling for evolutionary history. Here, we integrate field
observations and common garden experiments to quantify the relative importance
of pollination and herbivory in a pair of tropical‐temperate congeneric perennial
herbs. Phytolacca rivinoides and P. americana are pioneer species native to the
Neotropics and the eastern USA, respectively. We compared plant‐pollinator and
plant‐herbivore interactions between three tropical populations of P. rivinoides
from Costa Rica and three temperate populations of P. americana from its northern
range edge in Michigan and Ohio. For some metrics of interaction importance, we
also included three subtropical populations of P. americana from its southern
range edge in Florida. This approach confounds species and region but allows us,
uniquely, to measure complementary proxies of interaction importance across a
tropical‐temperate range in one system. To test the prediction that lower‐latitude
plants are more reliant on insect pollinators, we quantified floral display and
reward, insect visitation rates, and self‐pollination ability (autogamy). To test
the prediction that lower‐latitude plants experience more herbivore pressure,
we quantified herbivory rates, herbivore abundance, and leaf palatability. We
found evidence supporting the biotic interactions hypothesis for most comparisons
between P. rivinoides and north‐temperate P. americana (floral display, insect
visitation, autogamy, herbivory, herbivore abundance, and young‐leaf palatability).
Results for subtropical P. americana populations, however, were typically not
intermediate between P. rivinoides and north‐temperate P. americana, as would
be predicted by a linear latitudinal gradient in interaction importance. Subtropical
young‐leaf palatability was intermediate, but subtropical mature leaves were the
least palatable, and pollination‐related traits did not differ between temperate
and subtropical regions. These nonlinear patterns of interaction importance suggest
future work to relate interaction importance to climatic or biotic thresholds.
In sum, we found that the biotic interactions hypothesis was more consistently
supported at the larger spatial scale of our study.

text: "* Morphogenesis and adaptive tropic growth in plants depend on gradients
of the phytohormone auxin, mediated by the membrane‐based PIN‐FORMED (PIN) auxin
transporters. PINs localize to a particular side of the plasma membrane (PM) or
to the endoplasmic reticulum (ER) to directionally transport auxin and maintain
intercellular and intracellular auxin homeostasis, respectively. However, the
molecular cues that confer their diverse cellular localizations remain largely
unknown.\r\n* In this study, we systematically swapped the domains between ER‐
and PM‐localized PIN proteins, as well as between apical and basal PM‐localized
PINs from Arabidopsis thaliana , to shed light on why PIN family members with
similar topological structures reside at different membrane compartments within
cells.\r\n* Our results show that not only do the N‐ and C‐terminal transmembrane
domains (TMDs) and central hydrophilic loop contribute to their differential subcellular
localizations and cellular polarity, but that the pairwise‐matched N‐ and C‐terminal
TMDs resulting from intramolecular domain–domain coevolution are also crucial
for their divergent patterns of localization.\r\n* These findings illustrate the
complexity of the evolutionary path of PIN proteins in acquiring their plethora
of developmental functions and adaptive growth in plants."

text: This paper introduces a simple method for simulating highly anisotropic elastoplastic
material behaviors like the dissolution of fibrous phenomena (splintering wood,
shredding bales of hay) and materials composed of large numbers of irregularly‐shaped
bodies (piles of twigs, pencils, or cards). We introduce a simple transformation
of the anisotropic problem into an equivalent isotropic one, and we solve this
new “fictitious” isotropic problem using an existing simulator based on the material
point method. Our approach results in minimal changes to existing simulators,
and it allows us to re‐use popular isotropic plasticity models like the Drucker‐Prager
yield criterion instead of inventing new anisotropic plasticity models for every
phenomenon we wish to simulate.

text: Water-in-salt electrolytes based on highly concentrated bis(trifluoromethyl)sulfonimide
(TFSI) promise aqueous electrolytes with stabilities approaching 3 V. However,
especially with an electrode approaching the cathodic (reductive) stability, cycling
stability is insufficient. While stability critically relies on a solid electrolyte
interphase (SEI), the mechanism behind the cathodic stability limit remains unclear.
Here, we reveal two distinct reduction potentials for the chemical environments
of ‘free’ and ‘bound’ water and that both contribute to SEI formation. Free-water
is reduced ~1V above bound water in a hydrogen evolution reaction (HER) and responsible
for SEI formation via reactive intermediates of the HER; concurrent LiTFSI precipitation/dissolution
establishes a dynamic interface. The free-water population emerges, therefore,
as the handle to extend the cathodic limit of aqueous electrolytes and the battery
cycling stability.

studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defences of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal pathogen
species. Social immunity reduced virulence for all pathogen combinations, but
interfered with spore production only in different‐species coinfections. Here,
it decreased overall pathogen sporulation success while increasing co‐sporulation
on individual cadavers and maintaining a higher pathogen diversity at the community
level. Mathematical modelling revealed that host sanitary care alone can modulate
competitive outcomes between pathogens, giving advantage to fast‐germinating,
thus less grooming‐sensitive ones. Host social interactions can hence modulate
infection dynamics in coinfected group members, thereby altering pathogen communities
at the host level and population level.

text: Sewall Wright developed FST for describing population differentiation and
it has since been extended to many novel applications, including the detection
of homomorphic sex chromosomes. However, there has been confusion regarding the
expected estimate of FST for a fixed difference between the X‐ and Y‐chromosome
when comparing males and females. Here, we attempt to resolve this confusion by
contrasting two common FST estimators and explain why they yield different estimates
when applied to the case of sex chromosomes. We show that this difference is true
for many allele frequencies, but the situation characterized by fixed differences
between the X‐ and Y‐chromosome is among the most extreme. To avoid additional
confusion, we recommend that all authors using FST clearly state which estimator
of FST their work uses.

text: 'Water-in-salt electrolytes based on highly concentrated bis(trifluoromethyl)sulfonimide
(TFSI) promise aqueous electrolytes with stabilities nearing 3 V. However, especially
with an electrode approaching the cathodic (reductive) stability, cycling stability
is insufficient. While stability critically relies on a solid electrolyte interphase
(SEI), the mechanism behind the cathodic stability limit remains unclear. Here,
we reveal two distinct reduction potentials for the chemical environments of ''free''
and ''bound'' water and that both contribute to SEI formation. Free-water is reduced
~1V above bound water in a hydrogen evolution reaction (HER) and responsible for
SEI formation via reactive intermediates of the HER; concurrent LiTFSI precipitation/dissolution
establishes a dynamic interface. The free-water population emerges, therefore,
as the handle to extend the cathodic limit of aqueous electrolytes and the battery
cycling stability. '

text: 'Habitat loss is one of the key drivers of the ongoing decline of biodiversity.
However, ecologists still argue about how fragmentation of habitat (independent
of habitat loss) affects species richness. The recently proposed habitat amount
hypothesis posits that species richness only depends on the total amount of habitat
in a local landscape. In contrast, empirical studies report contrasting patterns:
some find positive and others negative effects of fragmentation per se on species
richness. To explain this apparent disparity, we devise a stochastic, spatially
explicit model of competitive species communities in heterogeneous habitats. The
model shows that habitat loss and fragmentation have complex effects on species
diversity in competitive communities. When the total amount of habitat is large,
fragmentation per se tends to increase species diversity, but if the total amount
of habitat is small, the situation is reversed: fragmentation per se decreases
species diversity.'

text: We show the synthesis of a redox‐active quinone, 2‐methoxy‐1,4‐hydroquinone
(MHQ), from a bio‐based feedstock and its suitability as electrolyte in aqueous
redox flow batteries. We identified semiquinone intermediates at insufficiently
low pH and quinoid radicals as responsible for decomposition of MHQ under electrochemical
conditions. Both can be avoided and/or stabilized, respectively, using H 3 PO
4 electrolyte, allowing for reversible cycling in a redox flow battery for hundreds
of cycles.

text: Coinfections with multiple pathogens can result in complex within-host dynamics
affecting virulence and transmission. Whilst multiple infections are intensively
studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defenses of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal
pathogen species. Social immunity reduced virulence for all pathogen combinations,
but interfered with spore production only in different-species coinfections. Here,
it decreased overall pathogen sporulation success, whilst simultaneously increasing
co-sporulation on individual cadavers and maintaining a higher pathogen diversity
at the community-level. Mathematical modeling revealed that host sanitary care
alone can modulate competitive outcomes between pathogens, giving advantage to
fast-germinating, thus less grooming-sensitive ones. Host social interactions
can hence modulate infection dynamics in coinfected group members, thereby altering
pathogen communities at the host- and population-level.

text: The hippocampus plays key roles in learning and memory and is a main target
of Alzheimer's disease (AD), which causes progressive memory impairments. Despite
numerous investigations about the processes required for the normal hippocampal
functions, the neurotransmitter receptors involved in the synaptic deficits by
which AD disables the hippocampus are not yet characterized. By combining histoblots,
western blots, immunohistochemistry and high‐resolution immunoelectron microscopic
methods for GABAB receptors, this study provides a quantitative description of
the expression and the subcellular localization of GABAB1 in the hippocampus in
a mouse model of AD at 1, 6 and 12 months of age. Western blots and histoblots
showed that the total amount of protein and the laminar expression pattern of
GABAB1 were similar in APP/PS1 mice and in age‐matched wild‐type mice. In contrast,
immunoelectron microscopic techniques showed that the subcellular localization
of GABAB1 subunit did not change significantly in APP/PS1 mice at 1 month of age,
was significantly reduced in the stratum lacunosum‐moleculare of CA1 pyramidal
cells at 6 months of age and significantly reduced at the membrane surface of
CA1 pyramidal cells at 12 months of age. This reduction of plasma membrane GABAB1
was paralleled by a significant increase of the subunit at the intracellular sites.
We further observed a decrease of membrane‐targeted GABAB receptors in axon terminals
contacting CA1 pyramidal cells. Our data demonstrate compartment‐ and age‐dependent
reduction of plasma membrane‐targeted GABAB receptors in the CA1 region of the
hippocampus, suggesting that this decrease might be enough to alter the GABAB‐mediated
synaptic transmission taking place in AD.

text: Genetic incompatibilities contribute to reproductive isolation between many
diverging populations, but it is still unclear to what extent they play a role
if divergence happens with gene flow. In contact zones between the "Crab" and
"Wave" ecotypes of the snail Littorina saxatilis, divergent selection forms strong
barriers to gene flow, while the role of post‐zygotic barriers due to selection
against hybrids remains unclear. High embryo abortion rates in this species could
indicate the presence of such barriers. Post‐zygotic barriers might include genetic
incompatibilities (e.g. Dobzhansky–Muller incompatibilities) but also maladaptation,
both expected to be most pronounced in contact zones. In addition, embryo abortion
might reflect physiological stress on females and embryos independent of any genetic
stress. We examined all embryos of >500 females sampled outside and inside contact
zones of three populations in Sweden. Females' clutch size ranged from 0 to 1,011
embryos (mean 130 ± 123), and abortion rates varied between 0% and 100% (mean
12%). We described female genotypes by using a hybrid index based on hundreds
of SNPs differentiated between ecotypes with which we characterized female genotypes.
We also calculated female SNP heterozygosity and inversion karyotype. Clutch size
did not vary with female hybrid index, and abortion rates were only weakly related
to hybrid index in two sites but not at all in a third site. No additional variation
in abortion rate was explained by female SNP heterozygosity, but increased female
inversion heterozygosity added slightly to increased abortion. Our results show
only weak and probably biologically insignificant post‐zygotic barriers contributing
to ecotype divergence, and the high and variable abortion rates were marginally,
if at all, explained by hybrid index of females.

text: Previously, we reported that the allelic de-etiolated by zinc (dez) and trichome
birefringence (tbr) mutants exhibit photomorphogenic development in the dark,
which is enhanced by high Zn. TRICHOME BIREFRINGENCE-LIKE proteins had been implicated
in transferring acetyl groups to various hemicelluloses. Pectin O-acetylation
levels were lower in dark-grown dez seedlings than in the wild type. We observed
Zn-enhanced photomorphogenesis in the dark also in the reduced wall acetylation
2 (rwa2-3) mutant, which exhibits lowered O-acetylation levels of cell wall macromolecules
including pectins and xyloglucans, supporting a role for cell wall macromolecule
O-acetylation in the photomorphogenic phenotypes of rwa2-3 and dez. Application
of very short oligogalacturonides (vsOGs) restored skotomorphogenesis in dark-grown
dez and rwa2-3. Here we demonstrate that in dez, O-acetylation of non-pectin cell
wall components, notably of xyloglucan, is enhanced. Our results highlight the
complexity of cell wall homeostasis and indicate against an influence of xyloglucan
O-acetylation on light-dependent seedling development.

text: For complex Wigner-type matrices, i.e. Hermitian random matrices with independent,
not necessarily identically distributed entries above the diagonal, we show that
at any cusp singularity of the limiting eigenvalue distribution the local eigenvalue
statistics are universal and form a Pearcey process. Since the density of states
typically exhibits only square root or cubic root cusp singularities, our work
complements previous results on the bulk and edge universality and it thus completes
the resolution of the Wigner–Dyson–Mehta universality conjecture for the last
remaining universality type in the complex Hermitian class. Our analysis holds
not only for exact cusps, but approximate cusps as well, where an extended Pearcey
process emerges. As a main technical ingredient we prove an optimal local law
at the cusp for both symmetry classes. This result is also the key input in the
companion paper (Cipolloni et al. in Pure Appl Anal, 2018. arXiv:1811.04055) where
the cusp universality for real symmetric Wigner-type matrices is proven. The novel
cusp fluctuation mechanism is also essential for the recent results on the spectral
radius of non-Hermitian random matrices (Alt et al. in Spectral radius of random
matrices with independent entries, 2019. arXiv:1907.13631), and the non-Hermitian
edge universality (Cipolloni et al. in Edge universality for non-Hermitian random
matrices, 2019. arXiv:1908.00969).

text: "This thesis is based on three main topics: In the first part, we study convergence
of discrete gradient flow structures associated with regular finite-volume discretisations
of Fokker-Planck equations. We show evolutionary I convergence of the discrete
gradient flows to the L2-Wasserstein gradient flow corresponding to the solution
of a Fokker-Planck\r\nequation in arbitrary dimension d >= 1. Along the argument,
we prove Mosco- and I-convergence results for discrete energy functionals, which
are of independent interest for convergence of equivalent gradient flow structures
in Hilbert spaces.\r\nThe second part investigates L2-Wasserstein flows on metric
graph. The starting point is a Benamou-Brenier formula for the L2-Wasserstein
distance, which is proved via a regularisation scheme for solutions of the continuity
equation, adapted to the peculiar geometric structure of metric graphs. Based
on those results, we show that the L2-Wasserstein space over a metric graph admits
a gradient flow which may be identified as a solution of a Fokker-Planck equation.\r\nIn
the third part, we focus again on the discrete gradient flows, already encountered
in the first part. We propose a variational structure which extends the gradient
flow structure to Markov chains violating the detailed-balance conditions. Using
this structure, we characterise contraction estimates for the discrete heat flow
in terms of convexity of\r\ncorresponding path-dependent energy functionals. In
addition, we use this approach to derive several functional inequalities for said
functionals."

text: "This thesis concerns itself with the interactions of evolutionary and ecological
forces and the consequences on genetic diversity and the ultimate survival of
populations. It is important to understand what signals processes \r\nleave on
the genome and what we can infer from such data, which is usually abundant but
noisy. Furthermore, understanding how and when populations adapt or go extinct
is important for practical purposes, such as the genetic management of populations,
as well as for theoretical questions, since local adaptation can be the first
step toward speciation. \r\nIn Chapter 2, we introduce the method of maximum entropy
to approximate the demographic changes of a population in a simple setting, namely
the logistic growth model with immigration. We show that this method is not only
a powerful \r\ntool in physics but can be gainfully applied in an ecological framework.
We investigate how well it approximates the real \r\nbehavior of the system, and
find that is does so, even in unexpected situations. Finally, we illustrate how
it can model changing environments.\r\nIn Chapter 3, we analyze the co-evolution
of allele frequencies and population sizes in an infinite island model.\r\nWe
give conditions under which polygenic adaptation to a rare habitat is possible.
The model we use is based on the diffusion approximation, considers eco-evolutionary
feedback mechanisms (hard selection), and treats both \r\ndrift and environmental
fluctuations explicitly. We also look at limiting scenarios, for which we derive
analytical expressions. \r\nIn Chapter 4, we present a coalescent based simulation
tool to obtain patterns of diversity in a spatially explicit subdivided population,
in which the demographic history of each subpopulation can be specified. We compare
\r\nthe results to existing predictions, and explore the relative importance of
time and space under a variety of spatial arrangements and demographic histories,
such as expansion and extinction. \r\nIn the last chapter, we give a brief outlook
to further research. "

text: "We study the interacting homogeneous Bose gas in two spatial dimensions in
the thermodynamic limit at fixed density. We shall be concerned with some mathematical
aspects of this complicated problem in many-body quantum mechanics. More specifically,
we consider the dilute limit where the scattering length of the interaction potential,
which is a measure for the effective range of the potential, is small compared
to the average distance between the particles. We are interested in a setting
with positive (i.e., non-zero) temperature. After giving a survey of the relevant
literature in the field, we provide some facts and examples to set expectations
for the two-dimensional system. The crucial difference to the three-dimensional
system is that there is no Bose–Einstein condensate at positive temperature due
to the Hohenberg–Mermin–Wagner theorem. However, it turns out that an asymptotic
formula for the free energy holds similarly to the three-dimensional case.\r\nWe
motivate this formula by considering a toy model with δ interaction potential.
By restricting this model Hamiltonian to certain trial states with a quasi-condensate
we obtain an upper bound for the free energy that still has the quasi-condensate
fraction as a free parameter. When minimizing over the quasi-condensate fraction,
we obtain the Berezinskii–Kosterlitz–Thouless critical temperature for superfluidity,
which plays an important role in our rigorous contribution. The mathematically
rigorous result that we prove concerns the specific free energy in the dilute
limit. We give upper and lower bounds on the free energy in terms of the free
energy of the non-interacting system and a correction term coming from the interaction.
Both bounds match and thus we obtain the leading term of an asymptotic approximation
in the dilute limit, provided the thermal wavelength of the particles is of the
same order (or larger) than the average distance between the particles. The remarkable
feature of this result is its generality: the correction term depends on the interaction
potential only through its scattering length and it holds for all nonnegative
interaction potentials with finite scattering length that are measurable. In particular,
this allows to model an interaction of hard disks."

text: "Mrp (Multi resistance and pH adaptation) are broadly distributed secondary
active antiporters that catalyze the transport of monovalent ions such as sodium
and potassium outside of the cell coupled to the inward translocation of protons.
Mrp antiporters are unique in a way that they are composed of seven subunits (MrpABCDEFG)
encoded in a single operon, whereas other antiporters catalyzing the same reaction
are mostly encoded by a single gene. Mrp exchangers are crucial for intracellular
pH homeostasis and Na+ efflux, essential mechanisms for H+ uptake under alkaline
environments and for reduction of the intracellular concentration of toxic cations.
Mrp displays no homology to any other monovalent Na+(K+)/H+ antiporters but Mrp
subunits have primary sequence similarity to essential redox-driven proton pumps,
such as respiratory complex I and membrane-bound hydrogenases. This similarity
reinforces the hypothesis that these present day redox-driven proton pumps are
descended from the Mrp antiporter. The Mrp structure serves as a model to understand
the yet obscure coupling mechanism between ion or electron transfer and proton
translocation in this large group of proteins. In the thesis, I am presenting
the purification, biochemical analysis, cryo-EM analysis and molecular structure
of the Mrp complex from Anoxybacillus flavithermus solved by cryo-EM at 3.0 Å
resolution. Numerous conditions were screened to purify Mrp to high homogeneity
and to obtain an appropriate distribution of single particles on cryo-EM grids
covered with a continuous layer of ultrathin carbon. A preferred particle orientation
problem was solved by performing a tilted data collection. The activity assays
showed the specific pH-dependent\r\nprofile of secondary active antiporters. The
molecular structure shows that Mrp is a dimer of seven-subunit protomers with
50 trans-membrane helices each. The dimer interface is built by many short and
tilted transmembrane helices, probably causing a thinning of the bacterial membrane.
The surface charge distribution shows an extraordinary asymmetry within each monomer,
revealing presumable proton and sodium translocation pathways. The two largest\r\nand
homologous Mrp subunits MrpA and MrpD probably translocate one proton each into
the cell. The sodium ion is likely being translocated in the opposite direction
within the small subunits along a ladder of charged and conserved residues. Based
on the structure, we propose a mechanism were the antiport activity is accomplished
via electrostatic interactions between the charged cations and key charged residues.
The flexible key TM helices coordinate these\r\nelectrostatic interactions, while
the membrane thinning between the monomers enables the translocation of sodium
across the charged membrane. The entire family of redox-driven proton pumps is
likely to perform their mechanism in a likewise manner."

text: The plant hormone auxin plays indispensable roles in plant growth and development.
An essential level of regulation in auxin action is the directional auxin transport
within cells. The establishment of auxin gradient in plant tissue has been attributed
to local auxin biosynthesis and directional intercellular auxin transport, which
both are controlled by various environmental and developmental signals. It is
well established that asymmetric auxin distribution in cells is achieved by polarly
localized PIN-FORMED (PIN) auxin efflux transporters. Despite the initial insights
into cellular mechanisms of PIN polarization obtained from the last decades, the
molecular mechanism and specific regulators mediating PIN polarization remains
elusive. In this thesis, we aim to find novel players in PIN subcellular polarity
regulation during Arabidopsis development. We first characterize the physiological
effect of piperonylic acid (PA) on Arabidopsis hypocotyl gravitropic bending and
PIN polarization. Secondly, we reveal the importance of SCFTIR1/AFB auxin signaling
pathway in shoot gravitropism bending termination. In addition, we also explore
the role of myosin XI complex, and actin cytoskeleton in auxin feedback regulation
on PIN polarity. In Chapter 1, we give an overview of the current knowledge about
PIN-mediated auxin fluxes in various plant tropic responses. In Chapter 2, we
study the physiological effect of PA on shoot gravitropic bending. Our results
show that PA treatment inhibits auxin-mediated PIN3 repolarization by interfering
with PINOID and PIN3 phosphorylation status, ultimately leading to hyperbending
hypocotyls. In Chapter 3, we provide evidence to show that the SCFTIR1/AFB nuclear
auxin signaling pathway is crucial and required for auxin-mediated PIN3 repolarization
and shoot gravitropic bending termination. In Chapter 4, we perform a phosphoproteomics
approach and identify the motor protein Myosin XI and its binding protein, the
MadB2 family, as an essential regulator of PIN polarity for auxin-canalization
related developmental processes. In Chapter 5, we demonstrate the vital role of
actin cytoskeleton in auxin feedback on PIN polarity by regulating PIN subcellular
trafficking. Overall, the data presented in this PhD thesis brings novel insights
into the PIN polar localization regulation that resulted in the (re)establishment
of the polar auxin flow and gradient in response to environmental stimuli during
plant development.

text: Multiple resistance and pH adaptation (Mrp) antiporters are multi-subunit
Na+ (or K+)/H+ exchangers representing an ancestor of many essential redox-driven
proton pumps, such as respiratory complex I. The mechanism of coupling between
ion or electron transfer and proton translocation in this large protein family
is unknown. Here, we present the structure of the Mrp complex from Anoxybacillus
flavithermus solved by cryo-EM at 3.0 Å resolution. It is a dimer of seven-subunit
protomers with 50 trans-membrane helices each. Surface charge distribution within
each monomer is remarkably asymmetric, revealing probable proton and sodium translocation
pathways. On the basis of the structure we propose a mechanism where the coupling
between sodium and proton translocation is facilitated by a series of electrostatic
interactions between a cation and key charged residues. This mechanism is likely
to be applicable to the entire family of redox proton pumps, where electron transfer
to substrates replaces cation movements.

text: "In the thesis we focus on the interplay of the biophysics and evolution of
gene regulation. We start by addressing how the type of prokaryotic gene regulation
– activation and repression – affects spurious binding to DNA, also known as\r\ntranscriptional
crosstalk. We propose that regulatory interference caused by excess regulatory
proteins in the dense cellular medium – global crosstalk – could be a factor in
determining which type of gene regulatory network is evolutionarily preferred.
Next,we use a normative approach in eukaryotic gene regulation to describe minimal\r\nnon-equilibrium
enhancer models that optimize so-called regulatory phenotypes. We find a class
of models that differ from standard thermodynamic equilibrium models by a single
parameter that notably increases the regulatory performance. Next chapter addresses
the question of genotype-phenotype-fitness maps of higher dimensional phenotypes.
We show that our biophysically realistic approach allows us to understand how
the mechanisms of promoter function constrain genotypephenotype maps, and how
they affect the evolutionary trajectories of promoters.\r\nIn the last chapter
we ask whether the intrinsic instability of gene duplication and amplification
provides a generic alternative to canonical gene regulation. Using mathematical
modeling, we show that amplifications can tune gene expression in many environments,
including those where transcription factor-based schemes are\r\nhard to evolve
or maintain. "

text: 'In prokaryotes, thermodynamic models of gene regulation provide a highly
quantitative mapping from promoter sequences to gene expression levels that is
compatible with in vivo and in vitro bio-physical measurements. Such concordance
has not been achieved for models of enhancer function in eukaryotes. In equilibrium
models, it is difficult to reconcile the reported short transcription factor (TF)
residence times on the DNA with the high specificity of regulation. In non-equilibrium
models, progress is difficult due to an explosion in the number of parameters.
Here, we navigate this complexity by looking for minimal non-equilibrium enhancer
models that yield desired regulatory phenotypes: low TF residence time, high specificity
and tunable cooperativity. We find that a single extra parameter, interpretable
as the “linking rate” by which bound TFs interact with Mediator components, enables
our models to escape equilibrium bounds and access optimal regulatory phenotypes,
while remaining consistent with the reported phenomenology and simple enough to
be inferred from upcoming experiments. We further find that high specificity in
non-equilibrium models is in a tradeoff with gene expression noise, predicting
bursty dynamics — an experimentally-observed hallmark of eukaryotic transcription.
By drastically reducing the vast parameter space to a much smaller subspace that
optimally realizes biological function prior to inference from data, our normative
approach holds promise for mathematical models in systems biology.'

text: "Many methods for the reconstruction of shapes from sets of points produce
ordered simplicial complexes, which are collections of vertices, edges, triangles,
and their higher-dimensional analogues, called simplices, in which every simplex
gets assigned a real value measuring its size. This thesis studies ordered simplicial
complexes, with a focus on their topology, which reflects the connectedness of
the represented shapes and the presence of holes. We are interested both in understanding
better the structure of these complexes, as well as in developing algorithms for
applications.\r\n\r\nFor the Delaunay triangulation, the most popular measure
for a simplex is the radius of the smallest empty circumsphere. Based on it, we
revisit Alpha and Wrap complexes and experimentally determine their probabilistic
properties for random data. Also, we prove the existence of tri-partitions, propose
algorithms to open and close holes, and extend the concepts from Euclidean to
Bregman geometries."

text: "A search problem lies in the complexity class FNP if a solution to the given
instance of the problem can be verified efficiently. The complexity class TFNP
consists of all search problems in FNP that are total in the sense that a solution
is guaranteed to exist. TFNP contains a host of interesting problems from fields
such as algorithmic game theory, computational topology, number theory and combinatorics.
Since TFNP is a semantic class, it is unlikely to have a complete problem. Instead,
one studies its syntactic subclasses which are defined based on the combinatorial
principle used to argue totality. Of particular interest is the subclass PPAD,
which contains important problems\r\nlike computing Nash equilibrium for bimatrix
games and computational counterparts of several fixed-point theorems as complete.
In the thesis, we undertake the study of averagecase hardness of TFNP, and in
particular its subclass PPAD.\r\nAlmost nothing was known about average-case hardness
of PPAD before a series of recent results showed how to achieve it using a cryptographic
primitive called program obfuscation.\r\nHowever, it is currently not known how
to construct program obfuscation from standard cryptographic assumptions. Therefore,
it is desirable to relax the assumption under which average-case hardness of PPAD
can be shown. In the thesis we take a step in this direction. First, we show that
assuming the (average-case) hardness of a numbertheoretic\r\nproblem related to
factoring of integers, which we call Iterated-Squaring, PPAD is hard-on-average
in the random-oracle model. Then we strengthen this result to show that the average-case
hardness of PPAD reduces to the (adaptive) soundness of the Fiat-Shamir Transform,
a well-known technique used to compile a public-coin interactive protocol into
a non-interactive one. As a corollary, we obtain average-case hardness for PPAD
in the random-oracle model assuming the worst-case hardness of #SAT. Moreover,
the above results can all be strengthened to obtain average-case hardness for
the class CLS ⊆ PPAD.\r\nOur main technical contribution is constructing incrementally-verifiable
procedures for computing Iterated-Squaring and #SAT. By incrementally-verifiable,
we mean that every intermediate state of the computation includes a proof of its
correctness, and the proof can be updated and verified in polynomial time. Previous
constructions of such procedures relied on strong, non-standard assumptions. Instead,
we introduce a technique called recursive proof-merging to obtain the same from
weaker assumptions. "

text: 'State-of-the-art detection systems are generally evaluated on their ability
to exhaustively retrieve objects densely distributed in the image, across a wide
variety of appearances and semantic categories. Orthogonal to this, many real-life
object detection applications, for example in remote sensing, instead require
dealing with large images that contain only a few small objects of a single class,
scattered heterogeneously across the space. In addition, they are often subject
to strict computational constraints, such as limited battery capacity and computing
power.To tackle these more practical scenarios, we propose a novel flexible detection
scheme that efficiently adapts to variable object sizes and densities: We rely
on a sequence of detection stages, each of which has the ability to predict groups
of objects as well as individuals. Similar to a detection cascade, this multi-stage
architecture spares computational effort by discarding large irrelevant regions
of the image early during the detection process. The ability to group objects
provides further computational and memory savings, as it allows working with lower
image resolutions in early stages, where groups are more easily detected than
individuals, as they are more salient. We report experimental results on two aerial
image datasets, and show that the proposed method is as accurate yet computationally
more efficient than standard single-shot detectors, consistently across three
different backbone architectures.'

text: 'Fine-tuning is a popular way of exploiting knowledge contained in a pre-trained
convolutional network for a new visual recognition task. However, the orthogonal
setting of transferring knowledge from a pretrained network to a visually different
yet semantically close source is rarely considered: This commonly happens with
real-life data, which is not necessarily as clean as the training source (noise,
geometric transformations, different modalities, etc.).To tackle such scenarios,
we introduce a new, generalized form of fine-tuning, called flex-tuning, in which
any individual unit (e.g. layer) of a network can be tuned, and the most promising
one is chosen automatically. In order to make the method appealing for practical
use, we propose two lightweight and faster selection procedures that prove to
be good approximations in practice. We study these selection criteria empirically
across a variety of domain shifts and data scarcity scenarios, and show that fine-tuning
individual units, despite its simplicity, yields very good results as an adaptation
technique. As it turns out, in contrast to common practice, rather than the last
fully-connected unit it is best to tune an intermediate or early one in many domain-
shift scenarios, which is accurately detected by flex-tuning.'

text: Image translation refers to the task of mapping images from a visual domain
to another. Given two unpaired collections of images, we aim to learn a mapping
between the corpus-level style of each collection, while preserving semantic content
shared across the two domains. We introduce xgan, a dual adversarial auto-encoder,
which captures a shared representation of the common domain semantic content in
an unsupervised way, while jointly learning the domain-to-domain image translations
in both directions. We exploit ideas from the domain adaptation literature and
define a semantic consistency loss which encourages the learned embedding to preserve
semantics shared across domains. We report promising qualitative results for the
task of face-to-cartoon translation. The cartoon dataset we collected for this
purpose, “CartoonSet”, is also publicly available as a new benchmark for semantic
style transfer at https://google.github.io/cartoonset/index.html.

text: "This thesis considers two examples of reconfiguration problems: flipping
edges in edge-labelled triangulations of planar point sets and swapping labelled
tokens placed on vertices of a graph. In both cases the studied structures – all
the triangulations of a given point set or all token placements on a given graph
– can be thought of as vertices of the so-called reconfiguration graph, in which
two vertices are adjacent if the corresponding structures differ by a single elementary
operation – by a flip of a diagonal in a triangulation or by a swap of tokens
on adjacent vertices, respectively. We study the reconfiguration of one instance
of a structure into another via (shortest) paths in the reconfiguration graph.\r\n\r\nFor
triangulations of point sets in which each edge has a unique label and a flip
transfers the label from the removed edge to the new edge, we prove a polynomial-time
testable condition, called the Orbit Theorem, that characterizes when two triangulations
of the same point set lie in the same connected component of the reconfiguration
graph. The condition was first conjectured by Bose, Lubiw, Pathak and Verdonschot.
We additionally provide a polynomial time algorithm that computes a reconfiguring
flip sequence, if it exists. Our proof of the Orbit Theorem uses topological properties
of a certain high-dimensional cell complex that has the usual reconfiguration
graph as its 1-skeleton.\r\n\r\nIn the context of token swapping on a tree graph,
we make partial progress on the problem of finding shortest reconfiguration sequences.
We disprove the so-called Happy Leaf Conjecture and demonstrate the importance
of swapping tokens that are already placed at the correct vertices. We also prove
that a generalization of the problem to weighted coloured token swapping is NP-hard
on trees but solvable in polynomial time on paths and stars."
