text: Aromatic side chains are important reporters of the plasticity of proteins,
and often form important contacts in protein–protein interactions. We studied
aromatic residues in the two structurally homologous cross-β amyloid fibrils HET-s,
and HELLF by employing a specific isotope-labeling approach and magic-angle-spinning
NMR. The dynamic behavior of the aromatic residues Phe and Tyr indicates that
the hydrophobic amyloid core is rigid, without any sign of "breathing motions"
over hundreds of milliseconds at least. Aromatic residues exposed at the fibril
surface have a rigid ring axis but undergo ring flips on a variety of time scales
from nanoseconds to microseconds. Our approach provides direct insight into hydrophobic-core
motions, enabling a better evaluation of the conformational heterogeneity generated
from an NMR structural ensemble of such amyloid cross-β architecture.

text: We study active surface wetting using a minimal model of bacteria that takes
into account the intrinsic motility diversity of living matter. A mixture of “fast”
and “slow” self-propelled Brownian particles is considered in the presence of
a wall. The evolution of the wetting layer thickness shows an overshoot before
stationarity and its composition evolves in two stages, equilibrating after a
slow elimination of excess particles. Nonmonotonic evolutions are shown to arise
from delayed avalanches towards the dilute phase combined with the emergence of
a transient particle front.

text: Turn-based stochastic games (aka simple stochastic games) are two-player zero-sum
games played on directed graphs with probabilistic transitions. The goal of player-max
is to maximize the probability to reach a target state against the adversarial
player-min. These games lie in NP ∩ coNP and are among the rare combinatorial
problems that belong to this complexity class for which the existence of polynomial-time
algorithm is a major open question. While randomized sub-exponential time algorithm
exists, all known deterministic algorithms require exponential time in the worst-case.
An important open question has been whether faster algorithms can be obtained
parametrized by the treewidth of the game graph. Even deterministic sub-exponential
time algorithm for constant treewidth turn-based stochastic games has remain elusive.
In this work our main result is a deterministic algorithm to solve turn-based
stochastic games that, given a game with n states, treewidth at most t, and the
bit-complexity of the probabilistic transition function log D, has running time
O ((tn2 log D)t log n). In particular, our algorithm is quasi-polynomial time
for games with constant or poly-logarithmic treewidth.

text: The celebrated Erdős–Ko–Rado theorem about the maximal size of an intersecting
family of r-element subsets of was extended to the setting of exterior algebra
in [5, Theorem 2.3] and in [6, Theorem 1.4]. However, the equality case has not
been settled yet. In this short note, we show that the extension of the Erdős–Ko–Rado
theorem and the characterization of the equality case therein, as well as those
of the Hilton–Milner theorem to the setting of exterior algebra in the simplest
non-trivial case of two-forms follow from a folklore puzzle about possible arrangements
of an intersecting family of lines.

text: "The process of detecting and evaluating sensory information to guide behaviour
is termed perceptual decision-making (PDM), and is critical for the ability of
an organism to interact with its external world. Individuals with autism, a neurodevelopmental
condition primarily characterised by social and communication difficulties, frequently
exhibit altered sensory processing and PDM difficulties are widely reported. Recent
technological advancements have pushed forward our understanding of the genetic
changes accompanying this condition, however our understanding of how these mutations
affect the function of specific neuronal circuits and bring about the corresponding
behavioural changes remains limited. Here, we use an innate PDM task, the looming
avoidance response (LAR) paradigm, to identify a convergent behavioural abnormality
across three molecularly distinct genetic mouse models of autism (Cul3, Setd5
and Ptchd1). Although mutant mice can rapidly detect threatening visual stimuli,
their responses are consistently delayed, requiring longer to initiate an appropriate
response than their wild-type siblings. Mutant animals show abnormal adaptation
in both their stimulus- evoked escape responses and exploratory dynamics following
repeated stimulus presentations. Similarly delayed behavioural responses are observed
in wild-type animals when faced with more ambiguous threats, suggesting the mutant
phenotype could arise from a dysfunction in the flexible control of this PDM process.\r\nOur
knowledge of the core neuronal circuitry mediating the LAR facilitated a detailed
dissection of the neuronal mechanisms underlying the behavioural impairment. In
vivo extracellular recording revealed that visual responses were unaffected within
a key brain region for the rapid processing of visual threats, the superior colliculus
(SC), indicating that the behavioural delay was unlikely to originate from sensory
impairments. Delayed behavioural responses were recapitulated in the Setd5 model
following optogenetic stimulation of the excitatory output neurons of the SC,
which are known to mediate escape initiation through the activation of cells in
the underlying dorsal periaqueductal grey (dPAG). In vitro patch-clamp recordings
of dPAG cells uncovered a stark hypoexcitability phenotype in two out of the three
genetic models investigated (Setd5 and Ptchd1), that in Setd5, is mediated by
the misregulation of voltage-gated potassium channels. Overall, our results show
that the ability to use visual information to drive efficient escape responses
is impaired in three diverse genetic mouse models of autism and that, in one of
the models studied, this behavioural delay likely originates from differences
in the intrinsic excitability of a key subcortical node, the dPAG. Furthermore,
this work showcases the use of an innate behavioural paradigm to mechanistically
dissect PDM processes in autism."

text: 'Lead halide perovskites enjoy a number of remarkable optoelectronic properties.
To explain their origin, it is necessary to study how electromagnetic fields interact
with these systems. We address this problem here by studying two classical quantities:
Faraday rotation and the complex refractive index in a paradigmatic perovskite
CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of
electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the
observed data even on the qualitative level. To amend this, we demonstrate that
there exists a relevant atomic-level coupling between electromagnetic fields and
the spin degree of freedom. This spin-electric coupling allows for quantitative
description of a number of previous as well as present experimental data. In particular,
we use it here to show that the Faraday effect in lead halide perovskites is dominated
by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel
contribution. Finally, we present general symmetry-based phenomenological arguments
that in the low-energy limit our effective model includes all basis coupling terms
to the electromagnetic field in the linear order.'

text: 'We use general symmetry-based arguments to construct an effective model suitable
for studying optical properties of lead halide perovskites. To build the model,
we identify an atomic-level interaction between electromagnetic fields and the
spin degree of freedom that should be added to a minimally coupled k⋅p Hamiltonian.
As a first application, we study two basic optical characteristics of the material:
the Verdet constant and the refractive index. Beyond these linear characteristics
of the material, the model is suitable for calculating nonlinear effects such
as the third-order optical susceptibility. Analysis of this quantity shows that
the geometrical properties of the spin-electric term imply isotropic optical response
of the system, and that optical anisotropy of lead halide perovskites is a manifestation
of hopping of charge carriers. To illustrate this, we discuss third-harmonic generation.'

text: "Most motions of many-body systems at any scale in nature with sufficient
degrees\r\nof freedom tend to be chaotic; reaching from the orbital motion of
planets, the air\r\ncurrents in our atmosphere, down to the water flowing through
our pipelines or\r\nthe movement of a population of bacteria. To the observer
it is therefore intriguing\r\nwhen a moving collective exhibits order. Collective
motion of flocks of birds, schools\r\nof fish or swarms of self-propelled particles
or robots have been studied extensively\r\nover the past decades but the mechanisms
involved in the transition from chaos to\r\norder remain unclear. Here, the interactions,
that in most systems give rise to chaos,\r\nsustain order. In this thesis we investigate
mechanisms that preserve, destabilize\r\nor lead to the ordered state. We show
that endothelial cells migrating in circular\r\nconfinements transition to a collective
rotating state and concomitantly synchronize\r\nthe frequencies of nucleating
actin waves within individual cells. Consequently,\r\nthe frequency dependent
cell migration speed uniformizes across the population.\r\nComplementary to the
WAVE dependent nucleation of traveling actin waves, we\r\nshow that in leukocytes
the actin polymerization depending on WASp generates\r\npushing forces locally
at stationary patches. Next, in pipe flows, we study methods\r\nto disrupt the
self–sustaining cycle of turbulence and therefore relaminarize the\r\nflow. While
we find in pulsating flow conditions that turbulence emerges through a\r\nhelical
instability during the decelerating phase. Finally, we show quantitatively in\r\nbrain
slices of mice that wild-type control neurons can compensate the migratory\r\ndeficits
of a genetically modified neuronal sub–population in the developing cortex."

text: "Nonergodic systems, whose out-of-equilibrium dynamics fail to thermalize,
provide a fascinating research direction both for fundamental reasons and for
application in state of the art quantum devices.\r\nGoing beyond the description
of statistical mechanics, ergodicity breaking yields a new paradigm in quantum
many-body physics, introducing novel phases of matter with no counterpart at equilibrium.\r\nIn
this Thesis, we address different open questions in the field, focusing on disorder-induced
many-body localization (MBL) and on weak ergodicity breaking in kinetically constrained
models.\r\nIn particular, we contribute to the debate about transport in kinetically
constrained models, studying the effect of $U(1)$ conservation and inversion-symmetry
breaking in a family of quantum East models.\r\nUsing tensor network techniques,
we analyze the dynamics of large MBL systems beyond the limit of exact numerical
methods.\r\nIn this setting, we approach the debated topic of the coexistence
of localized and thermal eigenstates separated by energy thresholds known as many-body
mobility edges.\r\nInspired by recent experiments, our work further investigates
the localization of a small bath induced by the coupling to a large localized
chain, the so-called MBL proximity effect.\r\n\r\nIn the first Chapter, we introduce
a family of particle-conserving kinetically constrained models, inspired by the
quantum East model.\r\nThe system we study features strong inversion-symmetry
breaking, due to the nature of the correlated hopping.\r\nWe show that these models
host so-called quantum Hilbert space fragmentation, consisting of disconnected
subsectors in an entangled basis, and further provide an analytical description
of this phenomenon.\r\nWe further probe its effect on dynamics of simple product
states, showing revivals in fidelity and local observalbes.\r\nThe study of dynamics
within the largest subsector reveals an anomalous transient superdiffusive behavior
crossing over to slow logarithmic dynamics at later times.\r\nThis work suggests
that particle conserving constrained models with inversion-symmetry breaking realize
new universality classes of dynamics and invite their further theoretical and
experimental studies.\r\n\r\nNext, we use kinetic constraints and disorder to
design a model with many-body mobility edges in particle density.\r\nThis feature
allows to study the dynamics of localized and thermal states in large systems
beyond the limitations of previous studies.\r\nThe time-evolution shows typical
signatures of localization at small densities, replaced by thermal behavior at
larger densities.\r\nOur results provide evidence in favor of the stability of
many-body mobility edges, which was recently challenged by a theoretical argument.\r\nTo
support our findings, we probe the mechanism proposed as a cause of delocalization
in many-body localized systems with mobility edges suggesting its ineffectiveness
in the model studied.\r\n\r\nIn the last Chapter of this Thesis, we address the
topic of many-body localization proximity effect.\r\nWe study a model inspired
by recent experiments, featuring Anderson localized coupled to a small bath of
free hard-core bosons.\r\nThe interaction among the two particle species results
in non-trivial dynamics, which we probe using tensor network techniques.\r\nOur
simulations show convincing evidence of many-body localization proximity effect
when the bath is composed by a single free particle and interactions are strong.\r\nWe
furthter observe an anomalous entanglement dynamics, which we explain through
a phenomenological theory.\r\nFinally, we extract highly excited eigenstates of
large systems, providing supplementary evidence in favor of our findings."

text: Although a wide variety of handcrafted concurrent data structures have been
proposed, there is considerable interest in universal approaches (Universal Constructions
or UCs) for building concurrent data structures. UCs (semi-)automatically convert
a sequential data structure into a concurrent one. The simplest approach uses
locks [3, 6] that protect a sequential data structure and allow only one process
to access it at a time. However, the resulting data structure is blocking. Most
work on UCs instead focuses on obtaining non-blocking progress guarantees such
as obstruction-freedom, lock-freedom or wait-freedom. Many non-blocking UCs have
appeared. Key examples include the seminal wait-free UC [2] by Herlihy, a NUMA-aware
UC [10] by Yi et al., and an efficient UC for large objects [1] by Fatourou et
al.

text: "During navigation, animals can infer the structure of the environment by
computing the optic flow cues elicited by their own movements, and subsequently
use this information to instruct proper locomotor actions. These computations
require a panoramic assessment of the visual environment in order to disambiguate
similar sensory experiences that may require distinct behavioral responses. The
estimation of the global motion patterns is therefore essential for successful
navigation. Yet, our understanding of the algorithms and implementations that
enable coherent panoramic visual perception remains scarce. Here I pursue this
problem by dissecting the functional aspects of interneuronal communication in
the lobula plate tangential cell network in Drosophila melanogaster. The results
presented in the thesis demonstrate that the basis for effective interpretation
of the optic flow in this circuit are stereotyped synaptic connections that mediate
the formation of distinct subnetworks, each extracting a particular pattern of
global motion. \r\nFirstly, I show that gap junctions are essential for a correct
interpretation of binocular motion cues by horizontal motion-sensitive cells.
HS cells form electrical synapses with contralateral H2 neurons that are involved
in detecting yaw rotation and translation. I developed an FlpStop-mediated mutant
of a gap junction protein ShakB that disrupts these electrical synapses. While
the loss of electrical synapses does not affect the tuning of the direction selectivity
in HS neurons, it severely alters their sensitivity to horizontal motion in the
contralateral side. These physiological changes result in an inappropriate integration
of binocular motion cues in walking animals. While wild-type flies form a binocular
perception of visual motion by non-linear integration of monocular optic flow
cues, the mutant flies sum the monocular inputs linearly. These results indicate
that rather than averaging signals in neighboring neurons, gap-junctions operate
in conjunction with chemical synapses to mediate complex non-linear optic flow
computations.\r\nSecondly, I show that stochastic manipulation of neuronal activity
in the lobula plate tangential cell network is a powerful approach to study the
neuronal implementation of optic flow-based navigation in flies. Tangential neurons
form multiple subnetworks, each mediating course-stabilizing response to a particular
global pattern of visual motion. Application of genetic mosaic techniques can
provide sparse optogenetic activation of HS cells in numerous combinations. These
distinct combinations of activated neurons drive an array of distinct behavioral
responses, providing important insights into how visuomotor transformation is
performed in the lobula plate tangential cell network. This approach can be complemented
by stochastic silencing of tangential neurons, enabling direct assessment of the
functional role of individual tangential neurons in the processing of specific
visual motion patterns.\r\n\tTaken together, the findings presented in this thesis
suggest that establishing specific activity patterns of tangential cells via stereotyped
synaptic connectivity is a key to efficient optic flow-based navigation in Drosophila
melanogaster."

text: "About a 100 years ago, we discovered that our universe is inherently noisy,
that is, measuring any physical quantity with a precision beyond a certain point
is not possible because of an omnipresent inherent noise. We call this - the quantum
noise. Certain physical processes allow this quantum noise to get correlated in
conjugate physical variables. These quantum correlations can be used to go beyond
the potential of our inherently noisy universe and obtain a quantum advantage
over the classical applications. \r\n\r\nQuantum noise being inherent also means
that, at the fundamental level, the physical quantities are not well defined and
therefore, objects can stay in multiple states at the same time. For example,
the position of a particle not being well defined means that the particle is in
multiple positions at the same time. About 4 decades ago, we started exploring
the possibility of using objects which can be in multiple states at the same time
to increase the dimensionality in computation. Thus, the field of quantum computing
was born. We discovered that using quantum entanglement, a property closely related
to quantum correlations, can be used to speed up computation of certain problems,
such as factorisation of large numbers, faster than any known classical algorithm.
Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
we have explored quantum control over many physical systems including photons,
spins, atoms, ions and even simple circuits made up of superconducting material.
However, there persists one ubiquitous theme. The more readily a system interacts
with an external field or matter, the more easily we can control it. But this
also means that such a system can easily interact with a noisy environment and
quickly lose its coherence. Consequently, such systems like electron spins need
to be protected from the environment to ensure the longevity of their coherence.
Other systems like nuclear spins are naturally protected as they do not interact
easily with the environment. But, due to the same reason, it is harder to interact
with such systems. \r\n\r\nAfter decades of experimentation with various systems,
we are convinced that no one type of quantum system would be the best for all
the quantum applications. We would need hybrid systems which are all interconnected
- much like the current internet where all sorts of devices can all talk to each
other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons
are the best contenders to carry information for the quantum internet. They can
carry quantum information cheaply and without much loss - the same reasons which
has made them the backbone of our current internet. Following this direction,
many systems, like trapped ions, have already demonstrated successful quantum
links over a large distances using optical photons. However, some of the most
promising contenders for quantum computing which are based on microwave frequencies
have been left behind. This is because high energy optical photons can adversely
affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
substantial progress on this missing quantum link between microwave and optics
using electrooptical nonlinearities in lithium niobate. The nonlinearities are
enhanced by using resonant cavities for all the involved modes leading to observation
of strong direct coupling between optical and microwave frequencies. With this
strong coupling we are not only able to achieve almost 100\\% internal conversion
efficiency with low added noise, thus presenting a quantum-enabled transducer,
but also we are able to observe novel effects such as cooling of a microwave mode
using optics. The strong coupling regime also leads to direct observation of dynamical
backaction effect between microwave and optical frequencies which are studied
in detail here. Finally, we also report first observation of microwave-optics
entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
\r\nWith this new bridge between microwave and optics, the microwave-based quantum
technologies can finally be a part of a quantum network which is based on optical
photons - putting us one step closer to a future with quantum internet. "

text: 'Deep neural networks (DNNs) often have to be compressed, via pruning and/or
quantization, before they can be deployed in practical settings. In this work
we propose a new compression-aware minimizer dubbed CrAM that modifies the optimization
step in a principled way, in order to produce models whose local loss behavior
is stable under compression operations such as pruning. Thus, dense models trained
via CrAM should be compressible post-training, in a single step, without significant
accuracy loss. Experimental results on standard benchmarks, such as residual networks
for ImageNet classification and BERT models for language modelling, show that
CrAM produces dense models that can be more accurate than the standard SGD/Adam-based
baselines, but which are stable under weight pruning: specifically, we can prune
models in one-shot to 70-80% sparsity with almost no accuracy loss, and to 90%
with reasonable (∼1%) accuracy loss, which is competitive with gradual compression
methods. Additionally, CrAM can produce sparse models which perform well for transfer
learning, and it also works for semi-structured 2:4 pruning patterns supported
by GPU hardware. The code for reproducing the results is available at this https

text: "Within the human body, the brain exhibits the highest rate of energy consumption
amongst all organs, with the majority of generated ATP being utilized to sustain
neuronal activity. Therefore, the metabolism of the mature cerebral cortex is
geared towards preserving metabolic homeostasis whilst generating significant
amounts of energy. This requires a precise interplay between diverse metabolic
pathways, spanning from a tissue-wide scale to the level of individual neurons.
Disturbances to this delicate metabolic equilibrium, such as those resulting from
maternal malnutrition\r\nor mutations affecting metabolic enzymes, often result
in neuropathological variants of neurodevelopment. For instance, mutations in
SLC7A5, a transporter of metabolically essential large neutral amino acids (LNAAs),
have been associated with autism and microcephaly. However, despite recent progress
in the field, the extent of metabolic restructuring that occurs within the developing
brain and the corresponding alterations in nutrient demands during various critical
periods remain largely unknown. To investigate this, we performed metabolomic
profiling of the murine cerebral cortex to characterize the metabolic state of
the forebrain at different developmental stages. We found that the developing
cortex undergoes substantial metabolic reprogramming, with specific sets of metabolites
displaying stage-specific changes. According to our observations, we determined
a distinct temporal period in postnatal development during which the cortex displays
heightened reliance on LNAAs. Hence, using a conditional knock-out mouse model,
we deleted Slc7a5 in neural cells, allowing us to monitor the impact of a perturbed
neuronal metabolic state across multiple developmental stages of corticogenesis.
We found that manipulating the levels of essential LNAAs in cortical neurons in
vivo affects one particular perinatal developmental period critical for cortical
network refinement. Abnormally low intracellular LNAA levels result in cell-autonomous
alterations in neuronal lipid metabolism, excitability, and survival during this
particular time window. Although most of the effects of Slc7a5 deletion on neuronal
physiology are transient, derailment of these processes during this brief but
crucial window leads to long-term circuit dysfunction in mice. In conclusion,
out data indicate that the cerebral cortex undergoes significant metabolic reorganization
during development. This process involves the intricate integration of multiple
metabolic pathways to ensure optimal neuronal function throughout different developmental
stages. Our findings offer a paradigm for understanding how neurons synchronize
the expression of nutrient-related genes with their activity to allow proper brain
maturation. Further, our results demonstrate that disruptions in these precisely
calibrated metabolic processes during critical periods of brain development may
result in neuropathological outcomes in mice and in humans."

text: "We consider the spin-\r\n1\r\n2\r\n Heisenberg chain (XXX model) weakly perturbed
away from integrability by an isotropic next-to-nearest neighbor exchange interaction.
Recently, it was conjectured that this model possesses an infinite tower of quasiconserved
integrals of motion (charges) [D. Kurlov et al., Phys. Rev. B 105, 104302 (2022)].
In this work we first test this conjecture by investigating how the norm of the
adiabatic gauge potential (AGP) scales with the system size, which is known to
be a remarkably accurate measure of chaos. We find that for the perturbed XXX
chain the behavior of the AGP norm corresponds to neither an integrable nor a
chaotic regime, which supports the conjectured quasi-integrability of the model.
We then prove the conjecture and explicitly construct the infinite set of quasiconserved
charges. Our proof relies on the fact that the XXX chain perturbed by next-to-nearest
exchange interaction can be viewed as a truncation of an integrable long-range
deformation of the Heisenberg spin chain."

text: Brachyury, a member of T-box gene family, is widely known for its major role
in mesoderm specification in bilaterians. It is also present in non-bilaterian
metazoans, such as cnidarians, where it acts as a component of an axial patterning
system. In this study, we present a phylogenetic analysis of Brachyury genes within
phylum Cnidaria, investigate differential expression and address a functional
framework of Brachyury paralogs in hydrozoan Dynamena pumila. Our analysis indicates
two duplication events of Brachyury within the cnidarian lineage. The first duplication
likely appeared in the medusozoan ancestor, resulting in two copies in medusozoans,
while the second duplication arose in the hydrozoan ancestor, resulting in three
copies in hydrozoans. Brachyury1 and 2 display a conservative expression pattern
marking the oral pole of the body axis in D. pumila. On the contrary, Brachyury3
expression was detected in scattered presumably nerve cells of the D. pumila larva.
Pharmacological modulations indicated that Brachyury3 is not under regulation
of cWnt signaling in contrast to the other two Brachyury genes. Divergence in
expression patterns and regulation suggest neofunctionalization of Brachyury3
in hydrozoans.
