  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
    of fluctuations in the stochastic quantities, thus extending the range of accessible
    times and system sizes compared to direct sampling. We discuss advantages and
    limitations of the proposed approach, outlining directions\r\nfor further developments."

  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.'

  text: "Blood – this is what animals use to heal wounds fast and efficient. Plants
    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.

  text: 'The developmental strategies used by progenitor cells to endure a safe journey
    from their induction place towards the site of terminal differentiation are still
    poorly understood. Here we uncovered a progenitor cell allocation mechanism that
    stems from an incomplete process of epithelial delamination that allows progenitors
    to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
    of the zebrafish laterality organ originate from the surface epithelial enveloping
    layer by an apical constriction process of cell delamination. During this process,
    progenitors retain long-term apical contacts that enable the epithelial layer
    to pull a subset of progenitors along their way towards the vegetal pole. The
    remaining delaminated progenitors follow apically-attached progenitors’ movement
    by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
    ensuring their fate and collective allocation at the differentiation site. Thus,
    we reveal that incomplete delamination serves as a cellular platform for coordinated
    tissue movements during development. Impact Statement: Incomplete delamination
    serves as a cellular platform for coordinated tissue movements during development,
    guiding newly formed progenitor cell groups to the differentiation site.'

  text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
    motivated alternative to backpropagation (BP), by substituting the computations
    that are unrealistic to be implemented in physical brains. While FA algorithms
    have been shown to work well in practice, there is a lack of rigorous theory proofing
    their learning capabilities. Here we introduce the first feedback alignment algorithm
    with provable learning guarantees. In contrast to existing work, we do not require
    any assumption about the size or depth of the network except that it has a single
    output neuron, i.e., such as for binary classification tasks. We show that our
    FA algorithm can deliver its theoretical promises in practice, surpassing the
    learning performance of existing FA methods and matching backpropagation in binary
    classification tasks. Finally, we demonstrate the limits of our FA variant when
    the number of output neurons grows beyond a certain quantity.

  text: We propose a neural information processing system obtained by re-purposing
    the function of a biological neural circuit model to govern simulated and real-world
    control tasks. Inspired by the structure of the nervous system of the soil-worm,
    C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model
    of biological neural circuits reparameterized for the control of alternative tasks.
    We first demonstrate that ONCs realize networks with higher maximum flow compared
    to arbitrary wired networks. We then learn instances of ONCs to control a series
    of robotic tasks, including the autonomous parking of a real-world rover robot.
    For reconfiguration of the purpose of the neural circuit, we adopt a search-based
    optimization algorithm. Ordinary neural circuits perform on par and, in some cases,
    significantly surpass the performance of contemporary deep learning models. ONC
    networks are compact, 77% sparser than their counterpart neural controllers, and
    their neural dynamics are fully interpretable at the cell-level.

  text: We introduce in this paper AMT2.0, a tool for qualitative and quantitative
    analysis of hybrid continuous and Boolean signals that combine numerical values
    and discrete events. The evaluation of the signals is based on rich temporal specifications
    expressed in extended signal temporal logic, which integrates timed regular expressions
    within signal temporal logic. The tool features qualitative monitoring (property
    satisfaction checking), trace diagnostics for explaining and justifying property
    violations and specification-driven measurement of quantitative features of the
    signal. We demonstrate the tool functionality on several running examples and
    case studies, and evaluate its performance.

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