text: 'Since the seminal studies by Osborne Reynolds in the nineteenth century,
pipe flow has served as a primary prototype for investigating the transition to
turbulence in wall-bounded flows. Despite the apparent simplicity of this flow,
various facets of this problem have occupied researchers for more than a century.
Here we review insights from three distinct perspectives: (a) stability and susceptibility
of laminar flow, (b) phase transition and spatiotemporal dynamics, and (c) dynamical
systems analysis of the Navier—Stokes equations. We show how these perspectives
have led to a profound understanding of the onset of turbulence in pipe flow.
Outstanding open points, applications to flows of complex fluids, and similarities
with other wall-bounded flows are discussed.'

text: We study the eigenvalue trajectories of a time dependent matrix Gt=H+itvv∗
for t≥0, where H is an N×N Hermitian random matrix and v is a unit vector. In
particular, we establish that with high probability, an outlier can be distinguished
at all times t>1+N−1/3+ϵ, for any ϵ>0. The study of this natural process combines
elements of Hermitian and non-Hermitian analysis, and illustrates some aspects
of the intrinsic instability of (even weakly) non-Hermitian matrices.

text: "Background: Fighting disease while fighting rivals exposes males to constraints
and tradeoffs during male-male competition. We here tested how both the stage
and intensity of infection with the fungal pathogen Metarhizium robertsii interfered
with fighting success in Cardiocondyla obscurior ant males. Males of this species
have evolved long lifespans during which they can gain many matings with the young
queens of the colony, if successful in male-male competition. Since male fights
occur inside the colony, the outcome of male-male competition can further be biased
by interference of the colony’s worker force.\r\nResults: We found that severe,
but not yet mild, infection strongly impaired male fighting success. In late-stage
infection, this could be attributed to worker aggression directed towards the
infected rather than the healthy male and an already very high male morbidity
even in the absence of fighting. Shortly after pathogen exposure, however, male
mortality was particularly increased during combat. Since these males mounted
a strong immune response, their reduced fighting success suggests a trade-off
between immune investment and competitive ability already early in the infection.
Even if the males themselves showed no difference in the number of attacks they
raised against their healthy rivals across infection stages and levels, severely
infected males were thus losing in male-male competition from an early stage of
infection on.\r\nConclusions: Males of the ant C. obscurior have evolved high
immune investment, triggering an effective immune response very fast after fungal
exposure. This allows them to cope with mild pathogen exposures without cost to
their success in male-male competition, and hence to gain multiple mating opportunities
with the emerging virgin queens of the colony. Under severe infection, however,
they are weak fighters and rarely survive a combat already at early infection
when raising an immune response, as well as at progressed infection, when they
are morbid and preferentially targeted by worker aggression. Workers thereby remove
males that pose a future disease threat by biasing male-male competition. Our
study thus revealed a novel social immunity mechanism how social insect workers
protect the colony against disease risk."

text: Models for same-material contact electrification in granular media often rely
on a local charge-driving parameter whose spatial variations lead to a stochastic
origin for charge exchange. Measuring the charge transfer from individual granular
spheres after contacts with substrates of the same material, we find instead a
“global” charging behavior, coherent over the sample’s whole surface. Cleaning
and baking samples fully resets charging magnitude and direction, which indicates
the underlying global parameter is not intrinsic to the material, but acquired
from its history. Charging behavior is randomly and irreversibly affected by changes
in relative humidity, hinting at a mechanism where adsorbates, in particular,
water, are fundamental to the charge-transfer process.

text: Hydrocarbon mixtures are extremely abundant in the Universe, and diamond formation
from them can play a crucial role in shaping the interior structure and evolution
of planets. With first-principles accuracy, we first estimate the melting line
of diamond, and then reveal the nature of chemical bonding in hydrocarbons at
extreme conditions. We finally establish the pressure-temperature phase boundary
where it is thermodynamically possible for diamond to form from hydrocarbon mixtures
with different atomic fractions of carbon. Notably, here we show a depletion zone
at pressures above 200 GPa and temperatures below 3000 K-3500 K where diamond
formation is thermodynamically favorable regardless of the carbon atomic fraction,
due to a phase separation mechanism. The cooler condition of the interior of Neptune
compared to Uranus means that the former is much more likely to contain the depletion
zone. Our findings can help explain the dichotomy of the two ice giants manifested
by the low luminosity of Uranus, and lead to a better understanding of (exo-)planetary
formation and evolution.

text: Adversarial training (i.e., training on adversarially perturbed input data)
is a well-studied method for making neural networks robust to potential adversarial
attacks during inference. However, the improved robustness does not come for free
but rather is accompanied by a decrease in overall model accuracy and performance.
Recent work has shown that, in practical robot learning applications, the effects
of adversarial training do not pose a fair trade-off but inflict a net loss when
measured in holistic robot performance. This work revisits the robustness-accuracy
trade-off in robot learning by systematically analyzing if recent advances in
robust training methods and theory in conjunction with adversarial robot learning,
are capable of making adversarial training suitable for real-world robot applications.
We evaluate three different robot learning tasks ranging from autonomous driving
in a high-fidelity environment amenable to sim-to-real deployment to mobile robot
navigation and gesture recognition. Our results demonstrate that, while these
techniques make incremental improvements on the trade-off on a relative scale,
the negative impact on the nominal accuracy caused by adversarial training still
outweighs the improved robustness by an order of magnitude. We conclude that although
progress is happening, further advances in robust learning methods are necessary
before they can benefit robot learning tasks in practice.

text: The elasticity of disordered and polydisperse polymer networks is a fundamental
problem of soft matter physics that is still open. Here, we self-assemble polymer
networks via simulations of a mixture of bivalent and tri- or tetravalent patchy
particles, which result in an exponential strand length distribution analogous
to that of experimental randomly cross-linked systems. After assembly, the network
connectivity and topology are frozen and the resulting system is characterized.
We find that the fractal structure of the network depends on the number density
at which the assembly has been carried out, but that systems with the same mean
valence and same assembly density have the same structural properties. Moreover,
we compute the long-time limit of the mean-squared displacement, also known as
the (squared) localization length, of the cross-links and of the middle monomers
of the strands, showing that the dynamics of long strands is well described by
the tube model. Finally, we find a relation connecting these two localization
lengths at high density and connect the cross-link localization length to the
shear modulus of the system.

text: Allometric settings of population dynamics models are appealing due to their
parsimonious nature and broad utility when studying system level effects. Here,
we parameterise the size-scaled Rosenzweig-MacArthur differential equations to
eliminate prey-mass dependency, facilitating an in depth analytic study of the
equations which incorporates scaling parameters’ contributions to coexistence.
We define the functional response term to match empirical findings, and examine
situations where metabolic theory derivations and observation diverge. The dynamical
properties of the Rosenzweig-MacArthur system, encompassing the distribution of
size-abundance equilibria, the scaling of period and amplitude of population cycling,
and relationships between predator and prey abundances, are consistent with empirical
observation. Our parameterisation is an accurate minimal model across 15+ orders
of mass magnitude.

text: We establish precise right-tail small deviation estimates for the largest
eigenvalue of real symmetric and complex Hermitian matrices whose entries are
independent random variables with uniformly bounded moments. The proof relies
on a Green function comparison along a continuous interpolating matrix flow for
a long time. Less precise estimates are also obtained in the left tail.

text: Self-organisation is the spontaneous emergence of spatio-temporal structures
and patterns from the interaction of smaller individual units. Examples are found
across many scales in very different systems and scientific disciplines, from
physics, materials science and robotics to biology, geophysics and astronomy.
Recent research has highlighted how self-organisation can be both mediated and
controlled by confinement. Confinement is an action over a system that limits
its units’ translational and rotational degrees of freedom, thus also influencing
the system's phase space probability density; it can function as either a catalyst
or inhibitor of self-organisation. Confinement can then become a means to actively
steer the emergence or suppression of collective phenomena in space and time.
Here, to provide a common framework and perspective for future research, we examine
the role of confinement in the self-organisation of soft-matter systems and identify
overarching scientific challenges that need to be addressed to harness its full
scientific and technological potential in soft matter and related fields. By drawing
analogies with other disciplines, this framework will accelerate a common deeper
understanding of self-organisation and trigger the development of innovative strategies
to steer it using confinement, with impact on, e.g., the design of smarter materials,
tissue engineering for biomedicine and in guiding active matter.

text: Given a finite set A ⊂ ℝ^d, let Cov_{r,k} denote the set of all points within
distance r to at least k points of A. Allowing r and k to vary, we obtain a 2-parameter
family of spaces that grow larger when r increases or k decreases, called the
multicover bifiltration. Motivated by the problem of computing the homology of
this bifiltration, we introduce two closely related combinatorial bifiltrations,
one polyhedral and the other simplicial, which are both topologically equivalent
to the multicover bifiltration and far smaller than a Čech-based model considered
in prior work of Sheehy. Our polyhedral construction is a bifiltration of the
rhomboid tiling of Edelsbrunner and Osang, and can be efficiently computed using
a variant of an algorithm given by these authors as well. Using an implementation
for dimension 2 and 3, we provide experimental results. Our simplicial construction
is useful for understanding the polyhedral construction and proving its correctness.

text: Surface curvature both emerges from, and influences the behavior of, living
objects at length scales ranging from cell membranes to single cells to tissues
and organs. The relevance of surface curvature in biology is supported by numerous
experimental and theoretical investigations in recent years. In this review, first,
a brief introduction to the key ideas of surface curvature in the context of biological
systems is given and the challenges that arise when measuring surface curvature
are discussed. Giving an overview of the emergence of curvature in biological
systems, its significance at different length scales becomes apparent. On the
other hand, summarizing current findings also shows that both single cells and
entire cell sheets, tissues or organisms respond to curvature by modulating their
shape and their migration behavior. Finally, the interplay between the distribution
of morphogens or micro-organisms and the emergence of curvature across length
scales is addressed with examples demonstrating these key mechanistic principles
of morphogenesis. Overall, this review highlights that curved interfaces are not
merely a passive by-product of the chemical, biological, and mechanical processes
but that curvature acts also as a signal that co-determines these processes.

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: "Background\r\nEpigenetic clocks can track both chronological age (cAge) and
biological age (bAge). The latter is typically defined by physiological biomarkers
and risk of adverse health outcomes, including all-cause mortality. As cohort
sample sizes increase, estimates of cAge and bAge become more precise. Here, we
aim to develop accurate epigenetic predictors of cAge and bAge, whilst improving
our understanding of their epigenomic architecture.\r\n\r\nMethods\r\nFirst, we
perform large-scale (N = 18,413) epigenome-wide association studies (EWAS) of
chronological age and all-cause mortality. Next, to create a cAge predictor, we
use methylation data from 24,674 participants from the Generation Scotland study,
the Lothian Birth Cohorts (LBC) of 1921 and 1936, and 8 other cohorts with publicly
available data. In addition, we train a predictor of time to all-cause mortality
as a proxy for bAge using the Generation Scotland cohort (1214 observed deaths).
For this purpose, we use epigenetic surrogates (EpiScores) for 109 plasma proteins
and the 8 component parts of GrimAge, one of the current best epigenetic predictors
of survival. We test this bAge predictor in four external cohorts (LBC1921, LBC1936,
the Framingham Heart Study and the Women’s Health Initiative study).\r\n\r\nResults\r\nThrough
the inclusion of linear and non-linear age-CpG associations from the EWAS, feature
pre-selection in advance of elastic net regression, and a leave-one-cohort-out
(LOCO) cross-validation framework, we obtain cAge prediction with a median absolute
error equal to 2.3 years. Our bAge predictor was found to slightly outperform
GrimAge in terms of the strength of its association to survival (HRGrimAge = 1.47
[1.40, 1.54] with p = 1.08 × 10−52, and HRbAge = 1.52 [1.44, 1.59] with p = 2.20 × 10−60).
Finally, we introduce MethylBrowsR, an online tool to visualise epigenome-wide
CpG-age associations.\r\n\r\nConclusions\r\nThe integration of multiple large
datasets, EpiScores, non-linear DNAm effects, and new approaches to feature selection
has facilitated improvements to the blood-based epigenetic prediction of biological
and chronological age."

text: Here we describe the in vivo DNA assembly approach, where molecular cloning
procedures are performed using an E. coli recA-independent recombination pathway,
which assembles linear fragments of DNA with short homologous termini. This pathway
is present in all standard laboratory E. coli strains and, by bypassing the need
for in vitro DNA assembly, allows simplified molecular cloning to be performed
without the plasmid instability issues associated with specialized recombination-cloning
bacterial strains. The methodology requires specific primer design and can perform
all standard plasmid modifications (insertions, deletions, mutagenesis, and sub-cloning)
in a rapid, simple, and cost-efficient manner, as it does not require commercial
kits or specialized bacterial strains. Additionally, this approach can be used
to perform complex procedures such as multiple modifications to a plasmid, as
up to 6 linear fragments can be assembled in vivo by this recombination pathway.
Procedures generally require less than 3 h, involving PCR amplification, DpnI
digestion of template DNA, and transformation, upon which circular plasmids are
assembled. In this chapter we describe the requirements, procedure, and potential
pitfalls when using this technique, as well as protocol variations to overcome
the most common issues.

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."
