text: "We study two-player zero-sum concurrent stochastic games with finite state
and action space played for an infinite number of steps. In every step, the two
players simultaneously and independently choose an action. Given the current state
and the chosen actions, the next state is obtained according to a stochastic transition
function. An objective is a measurable function on plays (or infinite trajectories)
of the game, and the value for an objective is the maximal expectation that the
player can guarantee against the adversarial player. We consider: (a) stateful-discounted
objectives, which are similar to the classical discounted-sum objectives, but
states are associated with different discount factors rather than a single discount
factor; and (b) parity objectives, which are a canonical representation for ω-regular
objectives. For stateful-discounted objectives, given an ordering of the discount
factors, the limit value is the limit of the value of the stateful-discounted
objectives, as the discount factors approach zero according to the given order.\r\nThe
computational problem we consider is the approximation of the value within an
arbitrary\r\nadditive error. The above problem is known to be in EXPSPACE for
the limit value of statefuldiscounted objectives and in PSPACE for parity objectives.
The best-known algorithms for both the above problems are at least exponential
time, with an exponential dependence on the number of states and actions. Our
main results for the value approximation problem for the limit value of stateful-discounted
objectives and parity objectives are as follows: (a) we establish TFNP[NP] complexity;
and (b) we present algorithms that improve the dependency on the number of actions
in the exponent from linear to logarithmic. In particular, if the number of states
is constant, our algorithms run in polynomial time."

text: "This paper considers a class of two-player zero-sum games on directed graphs
whose vertices are equipped with random payoffs of bounded support known by both
players.\r\nStarting from a fixed vertex, players take turns to move a token along
the edges of the graph.\r\nOn the one hand, for acyclic directed graphs of bounded
degree and sub-exponential expansion, we show that the value of the game converges
almost surely to a constant at an exponential rate dominated in terms of the expansion.\r\nOn
the other hand, for the infinite d-ary tree that does not fall into the previous
class of graphs, we show convergence at a double-exponential rate in terms of
the expansion."

text: Phytoalexin sakuranetin functions in resistance against rice blast. However,
the mechanisms underlying the effects of sakuranetin remains elusive. Here, we
report that rice lines expressing resistance (R) genes were found to contain high
levels of sakuranetin, which correlates with attenuated endocytic trafficking
of plasma membrane (PM) proteins. Exogenous and endogenous sakuranetin attenuates
the endocytosis of various PM proteins and the fungal effector PWL2. Moreover,
accumulation of the avirulence protein AvrCO39, resulting from uptake into rice
cells by Magnaporthe oryzae, was reduced following treatment with sakuranetin.
Pharmacological manipulation of clathrin-mediated endocytic (CME) suggests that
this pathway is targeted by sakuranetin. Indeed, attenuation of CME by sakuranetin
is sufficient to convey resistance against rice blast. Our data reveals a mechanism
of rice against M. oryzae by increasing sakuranetin levels and repressing the
CME of pathogen effectors, which is distinct from the action of many R genes that
mainly function by modulating transcription.

text: 'The homeostasis of epithelial tissue relies on a balance between the self-renewal
of stem cell populations, cellular differentiation, and loss. Although this balance
needs to be tightly regulated to avoid pathologies, such as tumor growth, the
regulatory mechanisms, both cell-intrinsic and collective, which ensure tissue
steady-state are still poorly understood. Here, we develop a computational model
that incorporates basic assumptions of stem cell renewal into distinct populations
and mechanical interactions between cells. We find that the model generates unexpected
dynamic features: stem cells repel each other in the bulk tissue and are thus
found rather isolated, as in a number of in vivo contexts. By mapping the system
onto a gas of passive Brownian particles with effective repulsive interactions,
that arise from the generated flows of differentiated cells, we show that we can
quantitatively describe such stem cell distribution in tissues. The interaction
potential between a pair of stem cells decays exponentially with a characteristic
length that spans several cell sizes, corresponding to the volume of cells generated
per stem cell division. Our findings may help understanding the dynamics of normal
and cancerous epithelial tissues.'

text: The development of photoresponsive systems with non-invasive orthogonal control
by distinct wavelengths of light is still in its infancy. In particular, the design
of photochemically triggered-orthogonal systems integrated into solid materials
that enable multiple dynamic control over their properties remains a longstanding
challenge. Here, we report the orthogonal and reversible control of two types
of photoswitches in an integrated solid porous framework, that is, visible-light
responsive o-fluoroazobenzene and nitro-spiropyran motifs. The properties of the
constructed material can be selectively controlled by different wavelengths of
light thus generating four distinct states providing a basis for dynamic multifunctional
materials. Solid-state NMR spectroscopy demonstrated the selective transformation
of the azobenzene switch in the bulk, which in turn modulates N2 and CO2 adsorption.

text: "Background: Motor alterations and lowered physical activity are common in
affective disorders. Previous research has indicated a link between depressive
symptoms and declining muscle strength primarily focusing on the elderly but not
younger individuals. Thus, we aimed to evaluate the relationship between mood
and muscle strength in a sample of N = 73 young to middle-aged hospitalized patients
(18–49 years, mean age 30.7 years) diagnosed with major depressive, bipolar and
schizoaffective disorder, with a focus on moderating effects of psychopharmacotherapy.
The study was carried out as a prospective observational study at a German psychiatric
university hospital between September 2021 and March 2022.\r\nMethods: Employing
a standardized strength circuit consisting of computerized strength training devices,
we measured the maximal muscle strength (Fmax) using three repetitions maximum
across four muscle regions (abdomen, arm, back, leg) at three time points (t1-t3)
over four weeks accompanied by psychometric testing (MADRS, BPRS, YRMS) and blood
lipid profiling in a clinical setting. For analysis of psychopharmacotherapy,
medication was split into activating (AM) and inhibiting (IM) medication and dosages
were normalized by the respective WHO defined daily dose.\r\nResults: While we
observed a significant decrease of the MADRS score and increase of the relative
total Fmax (rTFmax) in the first two weeks (t1-t2) but not later (both p < .001),
we did not reveal a significant bivariate correlation between disease severity
(MADRS) and muscle strength (rTFmax) at any of the timepoints. Individuals with
longer disease history displayed reduced rTFmax (p = .048). IM was significantly
associated with decreased rTFmax (p = .032). Regression models provide a more
substantial effect of gender, age, and IM on muscle strength than the depressive
episode itself (p < .001).\r\nConclusions: The results of the study indicate that
disease severity and muscle strength are not associated in young to middle-aged
inpatients with affective disorders using a strength circuit as observational
measurement. Future research will be needed to differentiate the effect of medication,
gender, and age on muscle strength and to develop interventions for prevention
of muscle weakness, especially in younger patients with chronic affective illnesses."

text: A key feature of many developmental systems is their ability to self-organize
spatial patterns of functionally distinct cell fates. To ensure proper biological
function, such patterns must be established reproducibly, by controlling and even
harnessing intrinsic and extrinsic fluctuations. While the relevant molecular
processes are increasingly well understood, we lack a principled framework to
quantify the performance of such stochastic self-organizing systems. To that end,
we introduce an information-theoretic measure for self-organized fate specification
during embryonic development. We show that the proposed measure assesses the total
information content of fate patterns and decomposes it into interpretable contributions
corresponding to the positional and correlational information. By optimizing the
proposed measure, our framework provides a normative theory for developmental
circuits, which we demonstrate on lateral inhibition, cell type proportioning,
and reaction–diffusion models of self-organization. This paves a way toward a
classification of developmental systems based on a common information-theoretic
language, thereby organizing the zoo of implicated chemical and mechanical signaling
processes.

text: 'In recent years, solution processes have gained considerable traction as
a cost-effective and scalable method to produce high-performance thermoelectric
materials. The process entails a series of critical steps: synthesis, purification,
thermal treatments, and consolidation, each playing a pivotal role in determining
performance, stability, and reproducibility. We have noticed a need for more comprehensive
details for each of the described steps in most published works. Recognizing the
significance of detailed synthetic protocols, we describe here the approach used
to synthesize and characterize one of the highest-performing polycrystalline p-type
SnSe. In particular, we report the synthesis of SnSe particles in water and the
subsequent surface treatment with CdSe molecular complexes that yields CdSe-SnSe
nanocomposites upon consolidation. Moreover, the surface treatment inhibits grain
growth through Zenner pinning of secondary phase CdSe nanoparticles and enhances
defect formation at different length scales. The enhanced complexity in the CdSe-SnSe
nanocomposite microstructure with respect to SnSe promotes phonon scattering and
thereby significantly reduces the thermal conductivity. Such surface engineering
provides opportunities in solution processing for introducing and controlling
defects, making it possible to optimize the transport properties and attain a
high thermoelectric figure of merit.'

text: We explore the potential of nanocrystals (a term used equivalently to nanoparticles)
as building blocks for nanomaterials, and the current advances and open challenges
for fundamental science developments and applications. Nanocrystal assemblies
are inherently multiscale, and the generation of revolutionary material properties
requires a precise understanding of the relationship between structure and function,
the former being determined by classical effects and the latter often by quantum
effects. With an emphasis on theory and computation, we discuss challenges that
hamper current assembly strategies and to what extent nanocrystal assemblies represent
thermodynamic equilibrium or kinetically trapped metastable states. We also examine
dynamic effects and optimization of assembly protocols. Finally, we discuss promising
material functions and examples of their realization with nanocrystal assemblies.

text: "Functional encryption (FE) is a primitive where the holder of a master secret
key can control which functions a user can evaluate on encrypted data. It is a
powerful primitive that even implies indistinguishability obfuscation (iO), given
sufficiently compact ciphertexts (Ananth-Jain, CRYPTO’15 and Bitansky-Vaikuntanathan,
FOCS’15). However, despite being extensively studied, there are FE schemes, such
as function-hiding inner-product FE (Bishop-Jain-Kowalczyk, AC’15, Abdalla-Catalano-Fiore-Gay-Ursu,
CRYPTO’18) and compact quadratic FE (Baltico-Catalano-Fiore-Gay, Lin, CRYPTO’17),
that can be only realized using pairings. This raises the question if there are
some mathematical barriers that hinder us from realizing these FE schemes from
other assumptions.\r\n\r\nIn this paper, we study the difficulty of constructing
lattice-based compact FE. We generalize the impossibility results of Ünal (EC’20)
for lattice-based function-hiding FE, and extend it to the case of compact FE.
Concretely, we prove lower bounds for lattice-based compact FE schemes which meet
some (natural) algebraic restrictions at encryption and decryption, and have ciphertexts
of linear size and secret keys of minimal degree. We see our results as important
indications of why it is hard to construct lattice-based FE schemes for new functionalities,
and which mathematical barriers have to be overcome."

We prove that the number of solutions (x1,…,xk,y1,…,yk)∈[N]2k to the equation\r\n∏1≤i≤kP(xi)=∏1≤j≤kP(yj)≠0\r\n(for
any k≥1 ) is asymptotically k!Nk as N→+∞. This solves a question first proposed

text: The onset of turbulence in pipe flow has defied detailed understanding ever
since the first observations of the spatially heterogeneous nature of the transition.
Recent theoretical studies and experiments in simpler, shear-driven flows suggest
that the onset of turbulence is a directed-percolation non-equilibrium phase transition,
but whether these findings are generic and also apply to open or pressure-driven
flows is unknown. In pipe flow, the extremely long time scales near the transition
make direct observations of critical behaviour virtually impossible. Here we find
a technical solution to that limitation and show that the universality class of
the transition is directed percolation, from which a jammed phase of puffs emerges
above the critical point. Our method is to experimentally characterize all pairwise
interactions between localized patches of turbulence puffs and use these interactions
as input for renormalization group and computer simulations of minimal models
that extrapolate to long length and time scales. The strong interactions in the
jamming regime enable us to explicitly measure the turbulent fraction and confirm
model predictions. Our work shows that directed-percolation scaling applies beyond
simple closed shear flows and underscores how statistical mechanics can lead to
profound, quantitative and predictive insights on turbulent flows and their phases.

text: "An ideal quantum computer relies on qubits capable of performing fast gate
operations and\r\nmaintaining strong interconnections while preserving their quantum
coherence. Since the\r\ninception of experimental eforts toward building a quantum
computer, the community has\r\nfaced challenges in engineering such a system.
Among the various methods of implementing a\r\nquantum computer, superconducting
qubits have shown fast gates close to tens of nanoseconds,\r\nwith the state-of-the-art
reaching a coherence of a few milliseconds. However, achieving\r\nsimultaneously
long lifetimes with fast qubit operations poses an inherent paradox. Qubits\r\nwith
high coherence require isolation from the environment, while fast operation necessitates\r\nstrong
coupling of the qubit. This thesis approaches this issue by proposing the idea
of\r\nengineering superconducting qubits capable of transitioning between operating
in a protected\r\nregime, where the qubit is completely isolated from the environment,
and coupling to the\r\ncommunication channels as needed. In this direction, we
use the geometric superinductor to\r\nscan the parameter space of rf-SQUID devices,
searching for a regime where we can take the\r\nqubit protection to its extreme.\r\n\r\nThis
leads us to the inductively shunted transmon (IST) regime, characterized by EJ
/EC ≫ 1\r\nand EJ /EL ≫ 1, where the circuit potential exhibits a double well
with a large barrier\r\nseparating the local ground states of each quantum well.
In this regime, although it is\r\nanticipated that the two quantum wells would
be isolated from each other, we observe single\r\nfuxon tunneling between them.
The interplay of the cavity photons and the fuxon transition\r\nforms a rich physical
system, containing resonance conditions that allow the preparation of the\r\nfuxon
ground or excited states. This enables us to study the relaxation rate of such
transition\r\nand show that it can be as large as 3.6 hours. Dynamically controlling
the barrier height\r\nbetween the two quantum wells allows for controllable coupling,
which scales exponentially,\r\nfor a qubit encoded in two fuxon states.\r\nThe
0-π qubit is one of the very few known superconducting circuit types that ofers
exponential\r\nprotection from both relaxation and dephasing simultaneously. However,
this qubit is not\r\nexempt from the fact that such protection comes at the expense
of complex readout and\r\ncontrol. In this thesis, we propose a way to controllably
break the circuit symmetry, the\r\nkey reason for the protection, to momentarily
restore the ability to control and manipulate\r\nthe qubit. An asymmetry in capacitances
and inductances in the 0-π circuit is detrimental\r\nsince they lead to coupling
of the protected state to the thermally occupied parasitic mode\r\nof the circuit.
However, here we try to exploit a controlled asymmetry in Josephson energies\r\nand
show that this can be used as a tunable coupler between the protected states.
In the\r\nfuture, this should allow to perform gate operations by dynamically
controlling the asymmetry\r\ninstead of driving the protected transition with
microwave pulses. Therefore, we believe that\r\nthe proposed method can make the
use of protected qubits more practical in experimental\r\nrealizations of quantum
computing."

text: The TIR1/AFB–Aux/IAA–ARF canonical auxin signaling pathway is widely accepted
to (de)active transcriptional regulation, thus controlling auxin-associated developmental
processes. However, the theme of a rapid auxin response has emerged since the
2018 Auxins and Cytokinin in Plant Development conference. To date, a few signaling
components have been identified to mediate both slow and rapid auxin responses,
which unveils the complexity of auxin signaling.

text: Despite the diverse genetic origins of autism spectrum disorders (ASDs), affected
individuals share strikingly similar and correlated behavioural traits that include
perceptual and sensory processing challenges. Notably, the severity of these sensory
symptoms is often predictive of the expression of other autistic traits. However,
the origin of these perceptual deficits remains largely elusive. Here, we show
a recurrent impairment in visual threat perception that is similarly impaired
in 3 independent mouse models of ASD with different molecular aetiologies. Interestingly,
this deficit is associated with reduced avoidance of threatening environments—a
nonperceptual trait. Focusing on a common cause of ASDs, the Setd5 gene mutation,
we define the molecular mechanism. We show that the perceptual impairment is caused
by a potassium channel (Kv1)-mediated hypoexcitability in a subcortical node essential
for the initiation of escape responses, the dorsal periaqueductal grey (dPAG).
Targeted pharmacological Kv1 blockade rescued both perceptual and place avoidance
deficits, causally linking seemingly unrelated trait deficits to the dPAG. Furthermore,
we show that different molecular mechanisms converge on similar behavioural phenotypes
by demonstrating that the autism models Cul3 and Ptchd1, despite having similar
behavioural phenotypes, differ in their functional and molecular alteration. Our
findings reveal a link between rapid perception controlled by subcortical pathways
and appropriate learned interactions with the environment and define a nondevelopmental
source of such deficits in ASD.

text: "This paper deals with local criteria for the convergence to a global minimiser
for gradient flow trajectories and their discretisations. To obtain quantitative
estimates on the speed of convergence, we consider variations on the classical
Kurdyka–Łojasiewicz inequality for a large class of parameter functions. Our assumptions
are given in terms of the initial data, without any reference to an equilibrium
point. The main results are convergence statements for gradient flow curves and
proximal point sequences to a global minimiser, together with sharp quantitative
estimates on the speed of convergence. These convergence results apply in the
general setting of lower semicontinuous functionals on complete metric spaces,
generalising recent results for smooth functionals on Rn. While the non-smooth
setting covers very general spaces, it is also useful for (non)-smooth functionals
on Rn.\r\n."

text: "We prove that the medial axis of closed sets is Hausdorff stable in the following
sense: Let \U0001D4AE ⊆ ℝ^d be a fixed closed set that contains a bounding sphere.
That is, the bounding sphere is part of the set \U0001D4AE. Consider the space
of C^{1,1} diffeomorphisms of ℝ^d to itself, which keep the bounding sphere invariant.
The map from this space of diffeomorphisms (endowed with a Banach norm) to the
space of closed subsets of ℝ^d (endowed with the Hausdorff distance), mapping
a diffeomorphism F to the closure of the medial axis of F(\U0001D4AE), is Lipschitz.
This extends a previous stability result of Chazal and Soufflet on the stability
of the medial axis of C² manifolds under C² ambient diffeomorphisms."

text: Grid peeling is the process of repeatedly removing the convex hull vertices
of the grid points that lie inside a given convex curve. It has been conjectured
that, for a more and more refined grid, grid peeling converges to a continuous
process, the affine curve-shortening flow, which deforms the curve based on the
curvature. We prove this conjecture for one class of curves, parabolas with a
vertical axis, and we determine the value of the constant factor in the formula
that relates the two processes.

text: The Upper Bound Theorem for convex polytopes implies that the p-th Betti number
of the Čech complex of any set of N points in ℝ^d and any radius satisfies β_p
= O(N^m), with m = min{p+1, ⌈d/2⌉}. We construct sets in even and odd dimensions,
which prove that this upper bound is asymptotically tight. For example, we describe
a set of N = 2(n+1) points in ℝ³ and two radii such that the first Betti number
of the Čech complex at one radius is (n+1)² - 1, and the second Betti number of
the Čech complex at the other radius is n². In particular, there is an arrangement
of n contruent balls in ℝ³ that enclose a quadratic number of voids, which answers
a long-standing open question in computational geometry.

text: Efficient utilization of large-scale biobank data is crucial for inferring
the genetic basis of disease and predicting health outcomes from the DNA. Yet
we lack efficient, accurate methods that scale to data where electronic health
records are linked to whole genome sequence information. To address this issue,
our paper develops a new algorithmic paradigm based on Approximate Message Passing
(AMP), which is specifically tailored for genomic prediction and association testing.
Our method yields comparable out-of-sample prediction accuracy to the state of
the art on UK Biobank traits, whilst dramatically improving computational complexity,
with a 8x-speed up in the run time. In addition, AMP theory provides a joint association
testing framework, which outperforms the currently used REGENIE method, in roughly
a third of the compute time. This first, truly large-scale application of the
AMP framework lays the foundations for a far wider range of statistical analyses
for hundreds of millions of variables measured on millions of people.
