  text: Asynchronous distributed algorithms are a popular way to reduce synchronization
    costs in large-scale optimization, and in particular for neural network training.
    However, for nonsmooth and nonconvex objectives, few convergence guarantees exist
    beyond cases where closed-form proximal operator solutions are available. As training
    most popular deep neural networks corresponds to optimizing nonsmooth and nonconvex
    objectives, there is a pressing need for such convergence guarantees. In this
    paper, we analyze for the first time the convergence of stochastic asynchronous
    optimization for this general class of objectives. In particular, we focus on
    stochastic subgradient methods allowing for block variable partitioning, where
    the shared model is asynchronously updated by concurrent processes. To this end,
    we use a probabilistic model which captures key features of real asynchronous
    scheduling between concurrent processes. Under this model, we establish convergence
    with probability one to an invariant set for stochastic subgradient methods with
    momentum. From a practical perspective, one issue with the family of algorithms
    that we consider is that they are not efficiently supported by machine learning
    frameworks, which mostly focus on distributed data-parallel strategies. To address
    this, we propose a new implementation strategy for shared-memory based training
    of deep neural networks for a partitioned but shared model in single- and multi-GPU
    settings. Based on this implementation, we achieve on average1.2x speed-up in
    comparison to state-of-the-art training methods for popular image classification
    tasks, without compromising accuracy.

  text: "We show that Neural ODEs, an emerging class of timecontinuous neural networks,
    can be verified by solving a set of global-optimization problems. For this purpose,
    we introduce Stochastic Lagrangian Reachability (SLR), an\r\nabstraction-based
    technique for constructing a tight Reachtube (an over-approximation of the set
    of reachable states\r\nover a given time-horizon), and provide stochastic guarantees
    in the form of confidence intervals for the Reachtube bounds. SLR inherently avoids
    the infamous wrapping effect (accumulation of over-approximation errors) by performing
    local optimization steps to expand safe regions instead of repeatedly forward-propagating
    them as is done by deterministic reachability methods. To enable fast local optimizations,
    we introduce a novel forward-mode adjoint sensitivity method to compute gradients
    without the need for backpropagation. Finally, we establish asymptotic and non-asymptotic
    convergence rates for SLR."

  text: "The scalability of concurrent data structures and distributed algorithms
    strongly depends on\r\nreducing the contention for shared resources and the costs
    of synchronization and communication. We show how such cost reductions can be
    attained by relaxing the strict consistency conditions required by sequential
    implementations. In the first part of the thesis, we consider relaxation in the
    context of concurrent data structures. Specifically, in data structures \r\nsuch
    as priority queues, imposing strong semantics renders scalability impossible,
    since a correct implementation of the remove operation should return only the
    element with highest priority. Intuitively, attempting to invoke remove operations
    concurrently  creates a race condition. This bottleneck  can be circumvented by
    relaxing semantics of the affected data structure, thus allowing removal of the
    elements which are no longer required to have the highest priority. We prove that
    the randomized implementations of relaxed data structures provide provable guarantees
    on the priority of the removed elements even under concurrency. Additionally,
    we show that in some cases the relaxed data structures can be used to scale the
    classical algorithms which are usually implemented with the exact ones. In the
    second part, we study parallel variants of the  stochastic gradient descent (SGD)
    algorithm, which distribute computation  among the multiple processors, thus reducing
    the running time. Unfortunately, in order for standard parallel SGD to succeed,
    each processor has to maintain a local copy of the necessary model parameter,
    which is identical to the local copies of other processors; the overheads from
    this perfect consistency in terms of communication and synchronization can negate
    the speedup gained by distributing the computation. We show that the consistency
    conditions required by SGD can be  relaxed, allowing the algorithm to be more
    flexible in terms of tolerating quantized communication, asynchrony, or even crash
    faults, while its convergence remains asymptotically the same."

  text: One key element behind the recent progress of machine learning has been the
    ability to train machine learning models in large-scale distributed shared-memory
    and message-passing environments. Most of these models are trained employing variants
    of stochastic gradient descent (SGD) based optimization, but most methods involve
    some type of consistency relaxation relative to sequential SGD, to mitigate its
    large communication or synchronization costs at scale. In this paper, we introduce
    a general consistency condition covering communication-reduced and asynchronous
    distributed SGD implementations. Our framework, called elastic consistency, decouples
    the system-specific aspects of the implementation from the SGD convergence requirements,
    giving a general way to obtain convergence bounds for a wide variety of distributed
    SGD methods used in practice. Elastic consistency can be used to re-derive or
    improve several previous convergence bounds in message-passing and shared-memory
    settings, but also to analyze new models and distribution schemes. As a direct
    application, we propose and analyze a new synchronization-avoiding scheduling
    scheme for distributed SGD, and show that it can be used to efficiently train
    deep convolutional models for image classification.

  text: "We compare the Manin-type conjecture for Campana points recently formulated\r\nby
    Pieropan, Smeets, Tanimoto and V\\'{a}rilly-Alvarado with an alternative\r\nprediction
    of Browning and Van Valckenborgh in the special case of the orbifold\r\n$(\\mathbb{P}^1,D)$,
    where $D =\\frac{1}{2}[0]+\\frac{1}{2}[1]+\\frac{1}{2}[\\infty]$. We find that
    the two predicted leading constants do not agree, and we discuss whether thin
    sets\r\ncould explain this discrepancy. Motivated by this, we provide a counterexample\r\nto
    the Manin-type conjecture for Campana points, by considering orbifolds\r\ncorresponding
    to squareful values of binary quadratic forms."

  text: "We show that turbulent dynamics that arise in simulations of the three-dimensional
    Navier--Stokes equations in a triply-periodic domain under sinusoidal forcing
    can be described as transient visits to the neighborhoods of unstable time-periodic
    solutions. Based on this description, we reduce the original system with more
    than 10^5 degrees of freedom to a 17-node Markov chain where each node corresponds
    to the neighborhood of a periodic orbit. The model accurately reproduces long-term
    averages of the system's observables as weighted sums over the periodic orbits.\r\n"

  text: 'Key trees are often the best solution in terms of transmission cost and storage
    requirements for managing keys in a setting where a group needs to share a secret
    key, while being able to efficiently rotate the key material of users (in order
    to recover from a potential compromise, or to add or remove users). Applications
    include multicast encryption protocols like LKH (Logical Key Hierarchies) or group
    messaging like the current IETF proposal TreeKEM. A key tree is a (typically balanced)
    binary tree, where each node is identified with a key: leaf nodes hold users’
    secret keys while the root is the shared group key. For a group of size N, each
    user just holds   log(N)  keys (the keys on the path from its leaf to the root)
    and its entire key material can be rotated by broadcasting   2log(N)  ciphertexts
    (encrypting each fresh key on the path under the keys of its parents). In this
    work we consider the natural setting where we have many groups with partially
    overlapping sets of users, and ask if we can find solutions where the cost of
    rotating a key is better than in the trivial one where we have a separate key
    tree for each group. We show that in an asymptotic setting (where the number m
    of groups is fixed while the number N of users grows) there exist more general
    key graphs whose cost converges to the cost of a single group, thus saving a factor
    linear in the number of groups over the trivial solution. As our asymptotic “solution”
    converges very slowly and performs poorly on concrete examples, we propose an
    algorithm that uses a natural heuristic to compute a key graph for any given group
    structure. Our algorithm combines two greedy algorithms, and is thus very efficient:
    it first converts the group structure into a “lattice graph”, which is then turned
    into a key graph by repeatedly applying the algorithm for constructing a Huffman
    code. To better understand how far our proposal is from an optimal solution, we
    prove lower bounds on the update cost of continuous group-key agreement and multicast
    encryption in a symbolic model admitting (asymmetric) encryption, pseudorandom
    generators, and secret sharing as building blocks.'

  text: 'Many security definitions come in two flavors: a stronger “adaptive” flavor,
    where the adversary can arbitrarily make various choices during the course of
    the attack, and a weaker “selective” flavor where the adversary must commit to
    some or all of their choices a-priori. For example, in the context of identity-based
    encryption, selective security requires the adversary to decide on the identity
    of the attacked party at the very beginning of the game whereas adaptive security
    allows the attacker to first see the master public key and some secret keys before
    making this choice. Often, it appears to be much easier to achieve selective security
    than it is to achieve adaptive security. A series of several recent works shows
    how to cleverly achieve adaptive security in several such scenarios including
    generalized selective decryption [Pan07][FJP15], constrained PRFs [FKPR14], and
    Yao’s garbled circuits [JW16]. Although the above works expressed vague intuition
    that they share a common technique, the connection was never made precise. In
    this work we present a new framework (published at Crypto ’17 [JKK+17a]) that
    connects all of these works and allows us to present them in a unified and simplified
    fashion. Having the framework in place, we show how to achieve adaptive security
    for proxy re-encryption schemes (published at PKC ’19 [FKKP19]) and provide the
    first adaptive security proofs for continuous group key agreement protocols (published
    at S&P ’21 [KPW+21]). Questioning optimality of our framework, we then show that
    currently used proof techniques cannot lead to significantly better security guarantees
    for "graph-building" games (published at TCC ’21 [KKPW21a]). These games cover
    generalized selective decryption, as well as the security of prominent constructions
    for constrained PRFs, continuous group key agreement, and proxy re-encryption.
    Finally, we revisit the adaptive security of Yao’s garbled circuits and extend
    the analysis of Jafargholi and Wichs in two directions: While they prove adaptive
    security only for a modified construction with increased online complexity, we
    provide the first positive results for the original construction by Yao (published
    at TCC ’21 [KKP21a]). On the negative side, we prove that the results of Jafargholi
    and Wichs are essentially optimal by showing that no black-box reduction can provide
    a significantly better security bound (published at Crypto ’21 [KKPW21c]).'

  text: "Automated contract tracing aims at supporting manual contact tracing during
    pandemics by alerting users of encounters with infected people. There are currently
    many proposals for protocols (like the “decentralized” DP-3T and PACT or the “centralized”
    ROBERT and DESIRE) to be run on mobile phones, where the basic idea is to regularly
    broadcast (using low energy Bluetooth) some values, and at the same time store
    (a function of) incoming messages broadcasted by users in their proximity. In
    the existing proposals one can trigger false positives on a massive scale by an
    “inverse-Sybil” attack, where a large number of devices (malicious users or hacked
    phones) pretend to be the same user, such that later, just a single person needs
    to be diagnosed (and allowed to upload) to trigger an alert for all users who
    were in proximity to any of this large group of devices.\r\n\r\nWe propose the
    first protocols that do not succumb to such attacks assuming the devices involved
    in the attack do not constantly communicate, which we observe is a necessary assumption.
    The high level idea of the protocols is to derive the values to be broadcasted
    by a hash chain, so that two (or more) devices who want to launch an inverse-Sybil
    attack will not be able to connect their respective chains and thus only one of
    them will be able to upload. Our protocols also achieve security against replay,
    belated replay, and one of them even against relay attacks."

  text: While messaging systems with strong security guarantees are widely used in
    practice, designing a protocol that scales efficiently to large groups and enjoys
    similar security guarantees remains largely open. The two existing proposals to
    date are ART (Cohn-Gordon et al., CCS18) and TreeKEM (IETF, The Messaging Layer
    Security Protocol, draft). TreeKEM is the currently considered candidate by the
    IETF MLS working group, but dynamic group operations (i.e. adding and removing
    users) can cause efficiency issues. In this paper we formalize and analyze a variant
    of TreeKEM which we term Tainted TreeKEM (TTKEM for short). The basic idea underlying
    TTKEM was suggested by Millican (MLS mailing list, February 2018). This version
    is more efficient than TreeKEM for some natural distributions of group operations,
    we quantify this through simulations.Our second contribution is two security proofs
    for TTKEM which establish post compromise and forward secrecy even against adaptive
    attackers. The security loss (to the underlying PKE) in the Random Oracle Model
    is a polynomial factor, and a quasipolynomial one in the Standard Model. Our proofs
    can be adapted to TreeKEM as well. Before our work no security proof for any TreeKEM-like
    protocol establishing tight security against an adversary who can adaptively choose
    the sequence of operations was known. We also are the first to prove (or even
    formalize) active security where the server can arbitrarily deviate from the protocol
    specification. Proving fully active security – where also the users can arbitrarily
    deviate – remains open.

  text: Elastic bending of initially flat slender elements allows the realization
    and economic fabrication of intriguing curved shapes. In this work, we derive
    an intuitive but rigorous geometric characterization of the design space of plane
    elastic rods with variable stiffness. It enables designers to determine which
    shapes are physically viable with active bending by visual inspection alone. Building
    on these insights, we propose a method for efficiently designing the geometry
    of a flat elastic rod that realizes a target equilibrium curve, which only requires
    solving a linear program. We implement this method in an interactive computational
    design tool that gives feedback about the feasibility of a design, and computes
    the geometry of the structural elements necessary to realize it within an instant.
    The tool also offers an iterative optimization routine that improves the fabricability
    of a model while modifying it as little as possible. In addition, we use our geometric
    characterization to derive an algorithm for analyzing and recovering the stability
    of elastic curves that would otherwise snap out of their unstable equilibrium
    shapes by buckling. We show the efficacy of our approach by designing and manufacturing
    several physical models that are assembled from flat elements.

  text: Collective cell migration offers a rich field of study for non-equilibrium
    physics and cellular biology, revealing phenomena such as glassy dynamics, pattern
    formation and active turbulence. However, how mechanical and chemical signalling
    are integrated at the cellular level to give rise to such collective behaviours
    remains unclear. We address this by focusing on the highly conserved phenomenon
    of spatiotemporal waves of density and extracellular signal-regulated kinase (ERK)
    activation, which appear both in vitro and in vivo during collective cell migration
    and wound healing. First, we propose a biophysical theory, backed by mechanical
    and optogenetic perturbation experiments, showing that patterns can be quantitatively
    explained by a mechanochemical coupling between active cellular tensions and the
    mechanosensitive ERK pathway. Next, we demonstrate how this biophysical mechanism
    can robustly induce long-ranged order and migration in a desired orientation,
    and we determine the theoretically optimal wavelength and period for inducing
    maximal migration towards free edges, which fits well with experimentally observed
    dynamics. We thereby provide a bridge between the biophysical origin of spatiotemporal
    instabilities and the design principles of robust and efficient long-ranged migration.

  text: De novo loss of function mutations in the ubiquitin ligase-encoding gene Cullin3
    lead to autism spectrum disorder (ASD). In mouse, constitutive haploinsufficiency
    leads to motor coordination deficits as well as ASD-relevant social and cognitive
    impairments. However, induction of Cul3 haploinsufficiency later in life does
    not lead to ASD-relevant behaviors, pointing to an important role of Cul3 during
    a critical developmental window. Here we show that Cul3 is essential to regulate
    neuronal migration and, therefore, constitutive Cul3 heterozygous mutant mice
    display cortical lamination abnormalities. At the molecular level, we found that
    Cul3 controls neuronal migration by tightly regulating the amount of Plastin3
    (Pls3), a previously unrecognized player of neural migration. Furthermore, we
    found that Pls3 cell-autonomously regulates cell migration by regulating actin
    cytoskeleton organization, and its levels are inversely proportional to neural
    migration speed. Finally, we provide evidence that cellular phenotypes associated
    with autism-linked gene haploinsufficiency can be rescued by transcriptional activation
    of the intact allele in vitro, offering a proof of concept for a potential therapeutic
    approach for ASDs.

  text: During development, a single cell is transformed into a highly complex organism
    through progressive cell division, specification and rearrangement. An important
    prerequisite for the emergence of patterns within the developing organism is to
    establish asymmetries at various scales, ranging from individual cells to the
    entire embryo, eventually giving rise to the different body structures. This becomes
    especially apparent during gastrulation, when the earliest major lineage restriction
    events lead to the formation of the different germ layers. Traditionally, the
    unfolding of the developmental program from symmetry breaking to germ layer formation
    has been studied by dissecting the contributions of different signaling pathways
    and cellular rearrangements in the in vivo context of intact embryos. Recent efforts,
    using the intrinsic capacity of embryonic stem cells to self-assemble and generate
    embryo-like structures de novo, have opened new avenues for understanding the
    many ways by which an embryo can be built and the influence of extrinsic factors
    therein. Here, we discuss and compare divergent and conserved strategies leading
    to germ layer formation in embryos as compared to in vitro systems, their upstream
    molecular cascades and the role of extrinsic factors in this process.

  text: 'The way in which interactions between mechanics and biochemistry lead to
    the emergence of complex cell and tissue organization is an old question that
    has recently attracted renewed interest from biologists, physicists, mathematicians
    and computer scientists. Rapid advances in optical physics, microscopy and computational
    image analysis have greatly enhanced our ability to observe and quantify spatiotemporal
    patterns of signalling, force generation, deformation, and flow in living cells
    and tissues. Powerful new tools for genetic, biophysical and optogenetic manipulation
    are allowing us to perturb the underlying machinery that generates these patterns
    in increasingly sophisticated ways. Rapid advances in theory and computing have
    made it possible to construct predictive models that describe how cell and tissue
    organization and dynamics emerge from the local coupling of biochemistry and mechanics.
    Together, these advances have opened up a wealth of new opportunities to explore
    how mechanochemical patterning shapes organismal development. In this roadmap,
    we present a series of forward-looking case studies on mechanochemical patterning
    in development, written by scientists working at the interface between the physical
    and biological sciences, and covering a wide range of spatial and temporal scales,
    organisms, and modes of development. Together, these contributions highlight the
    many ways in which the dynamic coupling of mechanics and biochemistry shapes biological
    dynamics: from mechanoenzymes that sense force to tune their activity and motor
    output, to collectives of cells in tissues that flow and redistribute biochemical
    signals during development.'

  text: Rigorous investigation of synaptic transmission requires analysis of unitary
    synaptic events by simultaneous recording from presynaptic terminals and postsynaptic
    target neurons. However, this has been achieved at only a limited number of model
    synapses, including the squid giant synapse and the mammalian calyx of Held. Cortical
    presynaptic terminals have been largely inaccessible to direct presynaptic recording,
    due to their small size. Here, we describe a protocol for improved subcellular
    patch-clamp recording in rat and mouse brain slices, with the synapse in a largely
    intact environment. Slice preparation takes ~2 h, recording ~3 h and post hoc
    morphological analysis 2 d. Single presynaptic hippocampal mossy fiber terminals
    are stimulated minimally invasively in the bouton-attached configuration, in which
    the cytoplasmic content remains unperturbed, or in the whole-bouton configuration,
    in which the cytoplasmic composition can be precisely controlled. Paired pre–postsynaptic
    recordings can be integrated with biocytin labeling and morphological analysis,
    allowing correlative investigation of synapse structure and function. Paired recordings
    can be obtained from mossy fiber terminals in slices from both rats and mice,
    implying applicability to genetically modified synapses. Paired recordings can
    also be performed together with axon tract stimulation or optogenetic activation,
    allowing comparison of unitary and compound synaptic events in the same target
    cell. Finally, paired recordings can be combined with spontaneous event analysis,
    permitting collection of miniature events generated at a single identified synapse.
    In conclusion, the subcellular patch-clamp techniques detailed here should facilitate
    analysis of biophysics, plasticity and circuit function of cortical synapses in
    the mammalian central nervous system.

  text: All vertebrates have a spinal cord with dimensions and shape specific to their
    species. Yet how species‐specific organ size and shape are achieved is a fundamental
    unresolved question in biology. The formation and sculpting of organs begins during
    embryonic development. As it develops, the spinal cord extends in anterior–posterior
    direction in synchrony with the overall growth of the body. The dorsoventral (DV)
    and apicobasal lengths of the spinal cord neuroepithelium also change, while at
    the same time a characteristic pattern of neural progenitor subtypes along the
    DV axis is established and elaborated. At the basis of these changes in tissue
    size and shape are biophysical determinants, such as the change in cell number,
    cell size and shape, and anisotropic tissue growth. These processes are controlled
    by global tissue‐scale regulators, such as morphogen signaling gradients as well
    as mechanical forces. Current challenges in the field are to uncover how these
    tissue‐scale regulatory mechanisms are translated to the cellular and molecular
    level, and how regulation of distinct cellular processes gives rise to an overall
    defined size. Addressing these questions will help not only to achieve a better
    understanding of how size is controlled, but also of how tissue size is coordinated
    with the specification of pattern.

  text: Aprotic alkali metal–O2 batteries face two major obstacles to their chemistry
    occurring efficiently, the insulating nature of the formed alkali superoxides/peroxides
    and parasitic reactions that are caused by the highly reactive singlet oxygen
    (1O2). Redox mediators are recognized to be key for improving rechargeability.
    However, it is unclear how they affect 1O2 formation, which hinders strategies
    for their improvement. Here we clarify the mechanism of mediated peroxide and
    superoxide oxidation and thus explain how redox mediators either enhance or suppress
    1O2 formation. We show that charging commences with peroxide oxidation to a superoxide
    intermediate and that redox potentials above ~3.5 V versus Li/Li+ drive 1O2 evolution
    from superoxide oxidation, while disproportionation always generates some 1O2.
    We find that 1O2 suppression requires oxidation to be faster than the generation
    of 1O2 from disproportionation. Oxidation rates decrease with growing driving
    force following Marcus inverted-region behaviour, establishing a region of maximum
    rate.

  text: Thermalization is the inevitable fate of many complex quantum systems, whose
    dynamics allow them to fully explore the vast configuration space regardless of
    the initial state---the behaviour known as quantum ergodicity. In a quest for
    experimental realizations of coherent long-time dynamics, efforts have focused
    on ergodicity-breaking mechanisms, such as integrability and localization. The
    recent discovery of persistent revivals in quantum simulators based on Rydberg
    atoms have pointed to the existence of a new type of behaviour where the system
    rapidly relaxes for most initial conditions, while certain initial states give
    rise to non-ergodic dynamics. This collective effect has been named ”quantum many-body
    scarring’by analogy with a related form of weak ergodicity breaking that occurs
    for a single particle inside a stadium billiard potential. In this Review, we
    provide a pedagogical introduction to quantum many-body scars and highlight the
    emerging connections with the semiclassical quantization of many-body systems.
    We discuss the relation between scars and more general routes towards weak violations
    of ergodicity due to embedded algebras and non-thermal eigenstates, and highlight
    possible applications of scars in quantum technology.

  text: Accumulation of interstitial fluid (IF) between embryonic cells is a common
    phenomenon in vertebrate embryogenesis. Unlike other model systems, where these
    accumulations coalesce into a large central cavity – the blastocoel, in zebrafish,
    IF is more uniformly distributed between the deep cells (DC) before the onset
    of gastrulation. This is likely due to the presence of a large extraembryonic
    structure – the yolk cell (YC) at the position where the blastocoel typically
    forms in other model organisms. IF has long been speculated to play a role in
    tissue morphogenesis during embryogenesis, but direct evidence supporting such
    function is still sparse. Here we show that the relocalization of IF to the interface
    between the YC and DC/epiblast is critical for axial mesendoderm (ME) cell protrusion
    formation and migration along this interface, a key process in embryonic axis
    formation. We further demonstrate that axial ME cell migration and IF relocalization
    engage in a positive feedback loop, where axial ME migration triggers IF accumulation
    ahead of the advancing axial ME tissue by mechanically compressing the overlying
    epiblast cell layer. Upon compression, locally induced flow relocalizes the IF
    through the porous epiblast tissue resulting in an IF accumulation ahead of the
    leading axial ME. This IF accumulation, in turn, promotes cell protrusion formation
    and migration of the leading axial ME cells, thereby facilitating axial ME extension.
    Our findings reveal a central role of dynamic IF relocalization in orchestrating
    germ layer morphogenesis during gastrulation.
