text: We argue that the time is ripe to investigate differential monitoring, in
which the specification of a program's behavior is implicitly given by a second
program implementing the same informal specification. Similar ideas have been
proposed before, and are currently implemented in restricted form for testing
and specialized run-time analyses, aspects of which we combine. We discuss the
challenges of implementing differential monitoring as a general-purpose, black-box
run-time monitoring framework, and present promising results of a preliminary
implementation, showing low monitoring overheads for diverse programs.

text: "There has recently been a surge of interest in the computational and complexity
properties of the population model, which assumes n anonymous, computationally-bounded
nodes, interacting at random, with the goal of jointly computing global predicates.
Significant work has gone towards investigating majority or consensus dynamics
in this model: that is, assuming that every node is initially in one of two states
X or Y, determine which state had higher initial count.\r\n\r\nIn this paper,
we consider a natural generalization of majority/consensus, which we call comparison
: in its simplest formulation, we are given two baseline states, X and Y, present
in any initial configuration in fixed, but possibly small counts. One of these
states has higher count than the other: we will assume |X_0| > C |Y_0| for some
constant C > 1. The challenge is to design a protocol by which nodes can quickly
and reliably decide on which of the baseline states X_0 and Y_0 has higher initial
count. We begin by analyzing a simple and general dynamics solving the above comparison
problem, which uses O( log n ) states per node, and converges in O(log n) (parallel)
time, with high probability, to a state where the whole population votes on opinions
X or Y at rates proportional to the initial concentrations of |X_0| vs. |Y_0|.
We then describe how this procedure can be bootstrapped to solve comparison, i.e.
have every node in the population reach the \"correct'' decision, with probability
1 - o(1), at the cost of O (log log n) additional states. Further, we prove that
this dynamics is self-stabilizing, in the sense that it converges to the correct
decision from arbitrary initial states, and leak-robust, in the sense that it
can withstand spurious faulty reactions, which are known to occur in practical
implementations of population protocols. Our analysis is based on a new martingale
concentration result relating the discrete-time evolution of a population protocol
to its expected (steady-state) analysis, which should be a useful tool when analyzing
opinion dynamics and epidemic dissemination in the population model."

text: Proper control of division orientation and symmetry, largely determined by
spindle positioning, is essential to development and homeostasis. Spindle positioning
has been extensively studied in cells dividing in two-dimensional (2D) environments
and in epithelial tissues, where proteins such as NuMA (also known as NUMA1) orient
division along the interphase long axis of the cell. However, little is known
about how cells control spindle positioning in three-dimensional (3D) environments,
such as early mammalian embryos and a variety of adult tissues. Here, we use mouse
embryonic stem cells (ESCs), which grow in 3D colonies, as a model to investigate
division in 3D. We observe that, at the periphery of 3D colonies, ESCs display
high spindle mobility and divide asymmetrically. Our data suggest that enhanced
spindle movements are due to unequal distribution of the cell–cell junction protein
E-cadherin between future daughter cells. Interestingly, when cells progress towards
differentiation, division becomes more symmetric, with more elongated shapes in
metaphase and enhanced cortical NuMA recruitment in anaphase. Altogether, this
study suggests that in 3D contexts, the geometry of the cell and its contacts
with neighbors control division orientation and symmetry.

text: Chronic psychological stress is one of the most important triggers and environmental
risk factors for neuropsychiatric disorders. Chronic stress can influence all
organs via the secretion of stress hormones, including glucocorticoids by the
adrenal glands, which coordinate the stress response across the body. In the brain,
glucocorticoid receptors (GR) are expressed by various cell types including microglia,
which are its resident immune cells regulating stress-induced inflammatory processes.
To study the roles of microglial GR under normal homeostatic conditions and following
chronic stress, we generated a mouse model in which the GR gene is depleted in
microglia specifically at adulthood to prevent developmental confounds. We first
confirmed that microglia were depleted in GR in our model in males and females
among the cingulate cortex and the hippocampus, both stress-sensitive brain regions.
Then, cohorts of microglial-GR depleted and wild-type (WT) adult female mice were
housed for 3 weeks in a standard or stressful condition, using a chronic unpredictable
mild stress (CUMS) paradigm. CUMS induced stress-related behavior in both microglial-GR
depleted and WT animals as demonstrated by a decrease of both saccharine preference
and progressive ratio breakpoint. Nevertheless, the hippocampal microglial and
neural mechanisms underlying the adaptation to stress occurred differently between
the two genotypes. Upon CUMS exposure, microglial morphology was altered in the
WT controls, without any apparent effect in microglial-GR depleted mice. Furthermore,
in the standard environment condition, GR depleted-microglia showed increased
expression of pro-inflammatory genes, and genes involved in microglial homeostatic
functions (such as Trem2, Cx3cr1 and Mertk). On the contrary, in CUMS condition,
GR depleted-microglia showed reduced expression levels of pro-inflammatory genes
and increased neuroprotective as well as anti-inflammatory genes compared to WT-microglia.
Moreover, in microglial-GR depleted mice, but not in WT mice, CUMS led to a significant
reduction of CA1 long-term potentiation and paired-pulse ratio. Lastly, differences
in adult hippocampal neurogenesis were observed between the genotypes during normal
homeostatic conditions, with microglial-GR deficiency increasing the formation
of newborn neurons in the dentate gyrus subgranular zone independently from stress
exposure. Together, these findings indicate that, although the deletion of microglial
GR did not prevent the animal’s ability to respond to stress, it contributed to
modulating hippocampal functions in both standard and stressful conditions, notably
by shaping the microglial response to chronic stress.

text: The reflectance field of a face describes the reflectance properties responsible
for complex lighting effects including diffuse, specular, inter-reflection and
self shadowing. Most existing methods for estimating the face reflectance from
a monocular image assume faces to be diffuse with very few approaches adding a
specular component. This still leaves out important perceptual aspects of reflectance
as higher-order global illumination effects and self-shadowing are not modeled.
We present a new neural representation for face reflectance where we can estimate
all components of the reflectance responsible for the final appearance from a
single monocular image. Instead of modeling each component of the reflectance
separately using parametric models, our neural representation allows us to generate
a basis set of faces in a geometric deformation-invariant space, parameterized
by the input light direction, viewpoint and face geometry. We learn to reconstruct
this reflectance field of a face just from a monocular image, which can be used
to render the face from any viewpoint in any light condition. Our method is trained
on a light-stage training dataset, which captures 300 people illuminated with
150 light conditions from 8 viewpoints. We show that our method outperforms existing
monocular reflectance reconstruction methods, in terms of photorealism due to
better capturing of physical premitives, such as sub-surface scattering, specularities,
self-shadows and other higher-order effects.

text: The control of many-body quantum dynamics in complex systems is a key challenge
in the quest to reliably produce and manipulate large-scale quantum entangled
states. Recently, quench experiments in Rydberg atom arrays [Bluvstein et al.
Science 371, 1355 (2021)] demonstrated that coherent revivals associated with
quantum many-body scars can be stabilized by periodic driving, generating stable
subharmonic responses over a wide parameter regime. We analyze a simple, related
model where these phenomena originate from spatiotemporal ordering in an effective
Floquet unitary, corresponding to discrete time-crystalline behavior in a prethermal
regime. Unlike conventional discrete time crystals, the subharmonic response exists
only for Néel-like initial states, associated with quantum scars. We predict robustness
to perturbations and identify emergent timescales that could be observed in future
experiments. Our results suggest a route to controlling entanglement in interacting
quantum systems by combining periodic driving with many-body scars.

text: The notion of Thouless energy plays a central role in the theory of Anderson
localization. We investigate and compare the scaling of Thouless energy across
the many-body localization (MBL) transition in a Floquet model. We use a combination
of methods that are reliable on the ergodic side of the transition (e.g., spectral
form factor) and methods that work on the MBL side (e.g., typical matrix elements
of local operators) to obtain a complete picture of the Thouless energy behavior
across the transition. On the ergodic side, Thouless energy decreases slowly with
the system size, while at the transition it becomes comparable to the level spacing.
Different probes yield consistent estimates of Thouless energy in their overlapping
regime of applicability, giving the location of the transition point nearly free
of finite-size drift. This work establishes a connection between different definitions
of Thouless energy in a many-body setting and yields insights into the MBL transition
in Floquet systems.

text: The brain is one of the largest and most complex organs and it is composed
of billions of neurons that communicate together enabling e.g. consciousness.
The cerebral cortex is the largest site of neural integration in the central nervous
system. Concerted radial migration of newly born cortical projection neurons,
from their birthplace to their final position, is a key step in the assembly of
the cerebral cortex. The cellular and molecular mechanisms regulating radial neuronal
migration in vivo are however still unclear. Recent evidence suggests that distinct
signaling cues act cell-autonomously but differentially at certain steps during
the overall migration process. Moreover, functional analysis of genetic mosaics
(mutant neurons present in wild-type/heterozygote environment) using the MADM
(Mosaic Analysis with Double Markers) analyses in comparison to global knockout
also indicate a significant degree of non-cell-autonomous and/or community effects
in the control of cortical neuron migration. The interactions of cell-intrinsic
(cell-autonomous) and cell-extrinsic (non-cell-autonomous) components are largely
unknown. In part of this thesis work we established a MADM-based experimental
strategy for the quantitative analysis of cell-autonomous gene function versus
non-cell-autonomous and/or community effects. The direct comparison of mutant
neurons from the genetic mosaic (cell-autonomous) to mutant neurons in the conditional
and/or global knockout (cell-autonomous + non-cell-autonomous) allows to quantitatively
analyze non-cell-autonomous effects. Such analysis enable the high-resolution
analysis of projection neuron migration dynamics in distinct environments with
concomitant isolation of genomic and proteomic profiles. Using these experimental
paradigms and in combination with computational modeling we show and characterize
the nature of non-cell-autonomous effects to coordinate radial neuron migration.
Furthermore, this thesis discusses recent developments in neurodevelopment with
focus on neuronal polarization and non-cell-autonomous mechanisms in neuronal
migration.

text: 'Payment channel networks are a promising approach to improve the scalability
of cryptocurrencies: they allow to perform transactions in a peer-to-peer fashion,
along multihop routes in the network, without requiring consensus on the blockchain.
However, during the discovery of cost-efficient routes for the transaction, critical
information may be revealed about the transacting entities. This paper initiates
the study of privacy-preserving route discovery mechanisms for payment channel
networks. In particular, we present LightPIR, an approach which allows a client
to learn the shortest (or cheapest in terms of fees) path between two nodes without
revealing any information about the endpoints of the transaction to the servers.
The two main observations which allow for an efficient solution in LightPIR are
that: (1) surprisingly, hub labelling algorithms – which were developed to preprocess
“street network like” graphs so one can later efficiently compute shortest paths
– also perform well for the graphs underlying payment channel networks, and that
(2) hub labelling algorithms can be conveniently combined with private information
retrieval. LightPIR relies on a simple hub labeling heuristic on top of existing
hub labeling algorithms which leverages the specific topological features of cryptocurrency
networks to further minimize storage and bandwidth overheads. In a case study
considering the Lightning network, we show that our approach is an order of magnitude
more efficient compared to a privacy-preserving baseline based on using private
information retrieval on a database that stores all pairs shortest paths.'

text: In this article we introduce a complete gradient estimate for symmetric quantum
Markov semigroups on von Neumann algebras equipped with a normal faithful tracial
state, which implies semi-convexity of the entropy with respect to the recently
introduced noncommutative 2-Wasserstein distance. We show that this complete gradient
estimate is stable under tensor products and free products and establish its validity
for a number of examples. As an application we prove a complete modified logarithmic
Sobolev inequality with optimal constant for Poisson-type semigroups on free group
factors.

text: Redox mediators could catalyse otherwise slow and energy-inefficient cycling
of Li-S and Li-O 2 batteries by shuttling electrons/holes between the electrode
and the solid insulating storage materials. For mediators to work efficiently
they need to oxidize the solid with fast kinetics yet the lowest possible overpotential.
Here, we found that when the redox potentials of mediators are tuned via, e.g.,
Li + concentration in the electrolyte, they exhibit distinct threshold potentials,
where the kinetics accelerate several-fold within a range as small as 10 mV. This
phenomenon is independent of types of mediators and electrolyte. The acceleration
originates from the overpotentials required to activate fast Li + /e – extraction
and the following chemical step at specific abundant surface facets. Efficient
redox catalysis at insulating solids requires therefore carefully considering
the surface conditions of the storage materials and electrolyte-dependent redox
potentials, which may be tuned by salt concentrations or solvents.

text: Insufficient understanding of the mechanism that reversibly converts sulphur
into lithium sulphide (Li2S) via soluble polysulphides (PS) hampers the realization
of high performance lithium-sulphur cells. Typically Li2S formation is explained
by direct electroreduction of a PS to Li2S; however, this is not consistent with
the size of the insulating Li2S deposits. Here, we use in situ small and wide
angle X-ray scattering (SAXS/WAXS) to track the growth and dissolution of crystalline
and amorphous deposits from atomic to sub-micron scales during charge and discharge.
Stochastic modelling based on the SAXS data allows quantification of the chemical
phase evolution during discharge and charge. We show that Li2S deposits predominantly
via disproportionation of transient, solid Li2S2 to form primary Li2S crystallites
and solid Li2S4 particles. We further demonstrate that this process happens in
reverse during charge. These findings show that the discharge capacity and rate
capability in Li-S battery cathodes are therefore limited by mass transport through
the increasingly tortuous network of Li2S / Li2S4 / carbon pores rather than electron
transport through a passivating surface film.

text: "The numerical simulation of dynamical phenomena in interacting quantum systems
is a notoriously hard problem. Although a number of promising numerical methods
exist, they often have limited applicability due to the growth of entanglement
or the presence of the so-called sign problem. In this work, we develop an importance
sampling scheme for the simulation of quantum spin dynamics, building on a recent
approach mapping quantum spin systems to classical stochastic processes. The importance
sampling scheme is based on identifying the classical trajectory that yields the
largest contribution to a given quantum observable. An exact transformation is
then carried out to preferentially sample trajectories that are close to the dominant
one. We demonstrate that this approach is capable of reducing the temporal growth

text: AMPA receptor (AMPAR) abundance and positioning at excitatory synapses regulates
the strength of transmission. Changes in AMPAR localisation can enact synaptic
plasticity, allowing long-term information storage, and is therefore tightly controlled.
Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but
with limited coherence or comparison between reports, our understanding of this
process is unclear. Here, combining synaptic recordings from mouse hippocampal
slices and super-resolution imaging in dissociated cultures, we compare the contributions
of three AMPAR interaction domains controlling transmission at hippocampal CA1
synapses. We show that the AMPAR C-termini play only a modulatory role, whereas
the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary
subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission.
Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density,
where the NTD further tunes their positioning. This interplay between cytosolic
(TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate
synaptic transmission and plasticity.

text: Size control is a fundamental question in biology, showing incremental complexity
in plants, whose cells possess a rigid cell wall. The phytohormone auxin is a
vital growth regulator with central importance for differential growth control.
Our results indicate that auxin-reliant growth programs affect the molecular complexity
of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent
induction and repression of growth coincide with reduced and enhanced molecular
complexity of xyloglucans, respectively. In agreement with a proposed function
in growth control, genetic interference with xyloglucan side decorations distinctly
modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent
growth programs have a spatially defined effect on xyloglucan’s molecular structure,
which in turn affects cell wall mechanics and specifies differential, gravitropic
hypocotyl growth.

text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
of concurrent programs. As scheduling non-determinism creates exponentially large
spaces of thread interleavings, SMC attempts to partition this space into equivalence
classes and explore only a few representatives from each class. The efficiency
of this approach depends on two factors: (a) the coarseness of the partitioning,
and (b) the time to generate representatives in each class. For this reason, the
search for coarse partitionings that are efficiently explorable is an active research
challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a
novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
deemed equivalent if they agree on the value obtained in each read event, and
read events induce consistent causal orderings between them. The RVF partitioning
is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
partitionings. Our experimental evaluation reveals that RVF is quite often a very
effective equivalence, as the underlying partitioning is exponentially coarser
than other approaches. Moreover, RVF-SMC generates representatives very efficiently,
as the reduction in the partitioning is often met with significant speed-ups in
the model checking task.'

do not have blood circulation and their cells cannot move. However, plants have
evolved remarkable capacities to regenerate tissues and organs preventing further
damage. In my PhD research, I studied the wound healing in the Arabidopsis root.
I used a UV laser to ablate single cells in the root tip and observed the consequent
wound healing. Interestingly, the inner adjacent cells induced a\r\ndivision plane
switch and subsequently adopted the cell type of the killed cell to replace it.
We termed this form of wound healing “restorative divisions”. This initial observation
triggered the questions of my PhD studies: How and why do cells orient their division
planes, how do they feel the wound and why does this happen only in inner adjacent
cells.\r\nFor answering these questions, I used a quite simple experimental setup:
5 day - old seedlings were stained with propidium iodide to visualize cell walls
and dead cells; ablation was carried out using a special laser cutter and a confocal
microscope. Adaptation of the novel vertical microscope system made it possible
to observe wounds in real time. This revealed that restorative divisions occur
at increased frequency compared to normal divisions. Additionally,\r\nthe major
plant hormone auxin accumulates in wound adjacent cells and drives the expression
of the wound-stress responsive transcription factor ERF115. Using this as a marker
gene for wound responses, we found that an important part of wound signalling
is the sensing of the collapse of the ablated cell. The collapse causes a radical
pressure drop, which results in strong tissue deformations. These deformations
manifest in an invasion of the now free spot specifically by the inner adjacent
cells within seconds, probably because of higher pressure of the inner tissues.
Long-term imaging revealed that those deformed cells continuously expand towards
the wound hole and that this is crucial for the restorative division. These wound-expanding
cells exhibit an abnormal, biphasic polarity of microtubule arrays\r\nbefore the
division. Experiments inhibiting cell expansion suggest that it is the biphasic
stretching that induces those MT arrays. Adapting the micromanipulator aspiration
system from animal scientists at our institute confirmed the hypothesis that stretching
influences microtubule stability. In conclusion, this shows that microtubules
react to tissue deformation\r\nand this facilitates the observed division plane
switch. This puts mechanical cues and tensions at the most prominent position
for explaining the growth and wound healing properties of plants. Hence, it shines
light onto the importance of understanding mechanical signal transduction. "

text: Indirect reciprocity is a mechanism for the evolution of cooperation based
on social norms. This mechanism requires that individuals in a population observe
and judge each other’s behaviors. Individuals with a good reputation are more
likely to receive help from others. Previous work suggests that indirect reciprocity
is only effective when all relevant information is reliable and publicly available.
Otherwise, individuals may disagree on how to assess others, even if they all
apply the same social norm. Such disagreements can lead to a breakdown of cooperation.
Here we explore whether the predominantly studied ‘leading eight’ social norms
of indirect reciprocity can be made more robust by equipping them with an element
of generosity. To this end, we distinguish between two kinds of generosity. According
to assessment generosity, individuals occasionally assign a good reputation to
group members who would usually be regarded as bad. According to action generosity,
individuals occasionally cooperate with group members with whom they would usually
defect. Using individual-based simulations, we show that the two kinds of generosity
have a very different effect on the resulting reputation dynamics. Assessment
generosity tends to add to the overall noise and allows defectors to invade. In
contrast, a limited amount of action generosity can be beneficial in a few cases.
However, even when action generosity is beneficial, the respective simulations
do not result in full cooperation. Our results suggest that while generosity can
favor cooperation when individuals use the most simple strategies of reciprocity,
it is disadvantageous when individuals use more complex social norms.

text: We define quantum equivariant K-theory of Nakajima quiver varieties. We discuss
type A in detail as well as its connections with quantum XXZ spin chains and trigonometric
Ruijsenaars-Schneider models. Finally we study a limit which produces a K-theoretic
version of results of Givental and Kim, connecting quantum geometry of flag varieties
and Toda lattice.
