  text: We consider a natural problem dealing with weighted packet selection across
    a rechargeable link, which e.g., finds applications in cryptocurrency networks.
    The capacity of a link (u, v) is determined by how much nodes u and v allocate
    for this link. Specifically, the input is a finite ordered sequence of packets
    that arrive in both directions along a link. Given (u, v) and a packet of weight
    x going from u to v, node u can either accept or reject the packet. If u accepts
    the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity
    on (u, v) increases by x. If a node rejects the packet, this will entail a cost
    affinely linear in the weight of the packet. A link is “rechargeable” in the sense
    that the total capacity of the link has to remain constant, but the allocation
    of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions.
    The goal is to minimise the sum of the capacity injected into the link and the
    cost of rejecting packets. We show that the problem is NP-hard, but can be approximated
    efficiently with a ratio of (1 + E) . (1 + square3) for some arbitrary E>0.

    the Dirichlet distribution on the standard simplex, in terms of the pattern\r\ninventory
    of the moments' exponents. We obtain analog formulas for the\r\nmultivariate moments

  text: Photosynthesis is among the first processes negatively affected by environmental
    cues and its performance directly determines plant cell fitness and ultimately
    crop yield. Primarily sites of photosynthesis, chloroplasts are unique sites also
    for the biosynthesis of precursors of the growth regulator auxin and for sensing
    environmental stress, but their role in intracellular auxin homeostasis, vital
    for plant growth and survival in changing environments, remains poorly understood.
    Here, we identified two ATP-binding cassette (ABC) subfamily B transporters, ABCB28
    and ABCB29, which export auxin across the chloroplast envelope to the cytosol
    in a concerted action in vivo. Moreover, we provide evidence for an auxin biosynthesis
    pathway in Arabidopsis thaliana chloroplasts. The overexpression of ABCB28 and
    ABCB29 influenced stomatal regulation and resulted in significantly improved water
    use efficiency and survival rates during salt and drought stresses. Our results
    suggest that chloroplast auxin production and transport contribute to stomata
    regulation for conserving water upon salt stress. ABCB28 and ABCB29 integrate
    photosynthesis and auxin signals and as such hold great potential to improve the
    adaptation potential of crops to environmental cues.

  text: This workshop continues a series of workshops whose current format originated
    in 1981 under then-organizers Moser and Zehnder, and whose latest iteration took
    place in July 2023. The general goal of this series of workshops is to discuss
    the latest developments in the field of dynamical systems, broadly construed,
    and its connections with neighboring areas of mathematics such as differential
    geometry, partial differential equations, and more recently contact and symplectic
    geometry. We continued this tradition, bringing in new participants working in
    areas of dynamical systems and its connections with other areas of mathematics
    that are currently highly active and/or showing great promise for future development.
    Key focus areas for the 2023 workshop include spectral rigidity for planar domains,
    chaotic and oscillatory motions in celestial mechanics, conformal symplectic dynamics,
    and relations between dynamics.he workshop by the grant DMS-2230648, “US Junior
    Oberwolfach Fellows”.

  text: "Sharding distributed ledgers is a promising on-chain solution for scaling
    blockchains but lacks formal grounds, nurturing skepticism on whether such complex
    systems can scale blockchains securely. We fill this gap by introducing the first
    formal framework as well as a roadmap to robust sharding. In particular, we first
    define the properties sharded distributed ledgers should fulfill. We build upon
    and extend the Bitcoin backbone protocol by defining consistency and scalability.
    Consistency encompasses the need for atomic execution of cross-shard transactions
    to preserve safety, whereas scalability encapsulates the speedup a sharded system
    can gain in comparison to a non-sharded system.\r\nUsing our model, we explore
    the limitations of sharding. We show that a sharded ledger with n participants
    cannot scale under a fully adaptive adversary, but it can scale up to m shards
    where n=c'm log m, under an epoch-adaptive adversary; the constant c' encompasses
    the trade-off between security and scalability. This is possible only if the sharded
    ledgers create succinct proofs of the valid state updates at every epoch. We leverage
    our results to identify the sufficient components for robust sharding, which we
    incorporate in a protocol abstraction termed Divide & Scale. To demonstrate the
    power of our framework, we analyze the most prominent sharded blockchains (Elastico,
    Monoxide, OmniLedger, RapidChain) and pinpoint where they fail to meet the desired
    properties."

  text: We unveil a powerful method for the stabilization of laser injection locking
    based on sensing variations in the output beam ellipticity of an optically seeded
    laser. The effect arises due to an interference between the seeding beam and the
    injected laser output. We demonstrate the method for a commercial semiconductor
    laser without the need for any internal changes to the readily operational injection
    locked laser system that was used. The method can also be used to increase the
    mode-hop free tuning range of lasers, and has the potential to fill a void in
    the low-noise laser industry.

  text: "Consider the random matrix model A1/2UBU∗A1/2, where A and B are two N ×
    N deterministic matrices and U is either an N × N Haar unitary or orthogonal random
    matrix. It is well known that on the macroscopic scale (Invent. Math. 104 (1991)
    201–220), the limiting empirical spectral distribution (ESD) of the above model
    is given by the free multiplicative convolution\r\nof the limiting ESDs of A and
    B, denoted as μα \x02 μβ, where μα and μβ are the limiting ESDs of A and B, respectively.
    In this paper, we study the asymptotic microscopic behavior of the edge eigenvalues
    and eigenvectors statistics. We prove that both the density of μA \x02μB, where
    μA and μB are the ESDs of A and B, respectively and the associated subordination
    functions\r\nhave a regular behavior near the edges. Moreover, we establish the
    local laws near the edges on the optimal scale. In particular, we prove that the
    entries of the resolvent are close to some functionals depending only on the eigenvalues
    of A, B and the subordination functions with optimal convergence rates. Our proofs
    and calculations are based on the techniques developed for the additive model
    A+UBU∗ in (J. Funct. Anal. 271 (2016) 672–719; Comm. Math.\r\nPhys. 349 (2017)
    947–990; Adv. Math. 319 (2017) 251–291; J. Funct. Anal. 279 (2020) 108639), and
    our results can be regarded as the counterparts of (J. Funct. Anal. 279 (2020)
    108639) for the multiplicative model. "

  text: 'We consider zero-error communication over a two-transmitter deterministic
    adversarial multiple access channel (MAC) governed by an adversary who has access
    to the transmissions of both senders (hence called omniscient ) and aims to maliciously
    corrupt the communication. None of the encoders, jammer and decoder is allowed
    to randomize using private or public randomness. This enforces a combinatorial
    nature of the problem. Our model covers a large family of channels studied in
    the literature, including all deterministic discrete memoryless noisy or noiseless
    MACs. In this work, given an arbitrary two-transmitter deterministic omniscient
    adversarial MAC, we characterize when the capacity region: 1) has nonempty interior
    (in particular, is two-dimensional); 2) consists of two line segments (in particular,
    has empty interior); 3) consists of one line segment (in particular, is one-dimensional);
    4) or only contains (0,0) (in particular, is zero-dimensional). This extends a
    recent result by Wang et al. (201 9) from the point-to-point setting to the multiple
    access setting. Indeed, our converse arguments build upon their generalized Plotkin
    bound and involve delicate case analysis. One of the technical challenges is to
    take care of both “joint confusability” and “marginal confusability”. In particular,
    the treatment of marginal confusability does not follow from the point-to-point
    results by Wang et al. Our achievability results follow from random coding with
    expurgation.'

  text: 'Radiative cooling of the lowest atmospheric levels is of strong importance
    for modulating atmospheric circulations and organizing convection, but detailed
    observations and a robust theoretical understanding are lacking. Here we use unprecedented
    observational constraints from subsidence regimes in the tropical Atlantic to
    develop a theory for the shape and magnitude of low‐level longwave radiative cooling
    in clear‐sky, showing peaks larger than 5–10 K/day at the top of the boundary
    layer. A suite of novel scaling approximations is first developed from simplified
    spectral theory, in close agreement with the measurements. The radiative cooling
    peak height is set by the maximum lapse rate in water vapor path, and its magnitude
    is mainly controlled by the ratio of column relative humidity above and below
    the peak. We emphasize how elevated intrusions of moist air can reduce low‐level
    cooling, by sporadically shading the spectral range which effectively cools to
    space. The efficiency of this spectral shading depends both on water content and
    altitude of moist intrusions; its height dependence cannot be explained by the
    temperature difference between the emitting and absorbing layers, but by the decrease
    of water vapor extinction with altitude. This analytical work can help to narrow
    the search for low‐level cloud patterns sensitive to radiative‐convective feedbacks:
    the most organized patterns with largest cloud fractions occur in atmospheres
    below 10% relative humidity and feel the strongest low‐level cooling. This motivates
    further assessment of favorable conditions for radiative‐convective feedbacks
    and a robust quantification of corresponding shallow cloud dynamics in current
    and warmer climates.'

  text: "Several fixed-target experiments reported J/ψ and ϒ polarizations, as functions
    of Feynman x (xF) and transverse momentum (PT), in three different frames, using
    different combinations of beam particles, target nuclei, and collision energies.
    Despite the diverse and heterogeneous picture formed by these measurements, a
    detailed look allows us to discern qualitative physical patterns that inspire
    a simple empirical model. This data-driven scenario offers a good quantitative
    description of the J/ψ and ϒ(1S) polarizations measured in proton- and pion-nucleus
    collisions, in the xF 0.5 domain: more than 80 data points (not statistically
    independent) are well reproduced with only one free parameter. This study sets
    the context for future low-PT\r\n quarkonium polarization measurements in proton-
    and pion-nucleus collisions, such as those to be made by the AMBER experiment,
    and shows that such measurements provide significant constraints on the poorly-known
    parton distribution functions of the pion."

  text: The large-scale laminar/turbulent spiral patterns that appear in the linearly
    unstable regime of counter-rotating Taylor–Couette flow are investigated from
    a statistical perspective by means of direct numerical simulation. Unlike the
    vast majority of previous numerical studies, we analyse the flow in periodic parallelogram-annular
    domains, following a coordinate change that aligns one of the parallelogram sides
    with the spiral pattern. The domain size, shape and spatial resolution have been
    varied and the results compared with those in a sufficiently large computational
    orthogonal domain with natural axial and azimuthal periodicity. We find that a
    minimal parallelogram of the right tilt significantly reduces the computational
    cost without notably compromising the statistical properties of the supercritical
    turbulent spiral. Its mean structure, obtained from extremely long time integrations
    in a co-rotating reference frame using the method of slices, bears remarkable
    similarity with the turbulent stripes observed in plane Couette flow, the centrifugal
    instability playing only a secondary role.

  text: We consider the sharp interface limit for the scalar-valued and vector-valued
    Allen–Cahn equation with homogeneous Neumann boundary condition in a bounded smooth
    domain Ω of arbitrary dimension N ⩾ 2 in the situation when a two-phase diffuse
    interface has developed and intersects the boundary ∂ Ω. The limit problem is
    mean curvature flow with 90°-contact angle and we show convergence in strong norms
    for well-prepared initial data as long as a smooth solution to the limit problem
    exists. To this end we assume that the limit problem has a smooth solution on
    [ 0 , T ] for some time T &gt; 0. Based on the latter we construct suitable curvilinear
    coordinates and set up an asymptotic expansion for the scalar-valued and the vector-valued
    Allen–Cahn equation. In order to estimate the difference of the exact and approximate
    solutions with a Gronwall-type argument, a spectral estimate for the linearized
    Allen–Cahn operator in both cases is required. The latter will be shown in a separate
    paper, cf. (Moser (2021)).

  text: "We prove the r-spin cobordism hypothesis in the setting of (weak) 2-categories
    for every positive integer r: the 2-groupoid of 2-dimensional fully extended r-spin
    TQFTs with given target is equivalent to the homotopy fixed points of an induced
    Spin 2r -action. In particular, such TQFTs are classified by fully dualisable
    objects together with a trivialisation of the rth power of their Serre automorphisms.
    For r=1, we recover the oriented case (on which our proof builds), while ordinary
    spin structures correspond to r=2.\r\nTo construct examples, we explicitly describe
    Spin 2r​-homotopy fixed points in the equivariant completion of any symmetric
    monoidal 2-category. We also show that every object in a 2-category of Landau–Ginzburg
    models gives rise to fully extended spin TQFTs and that half of these do not factor
    through the oriented bordism 2-category."

  text: The cerebral cortex is comprised of a vast cell-type diversity sequentially
    generated by cortical progenitor cells. Faithful progenitor lineage progression
    requires the tight orchestration of distinct molecular and cellular mechanisms
    regulating proper progenitor proliferation behavior and differentiation. Correct
    execution of developmental programs involves a complex interplay of cell intrinsic
    and tissue-wide mechanisms. Many studies over the past decades have been able
    to determine a plethora of genes critically involved in cortical development.
    However, only a few made use of genetic paradigms with sparse and global gene
    deletion to probe cell-autonomous vs. tissue-wide contribution. In this chapter,
    we will elaborate on the importance of dissecting the cell-autonomous and tissue-wide
    mechanisms to gain a precise understanding of gene function during radial glial
    progenitor lineage progression.

  text: 'We present a flexible and efficient toolchain to symbolically solve (standard)
    Rabin games, fair-adversarial Rabin games, and 2 1/2 license type-player Rabin
    games. To our best knowledge, our tools are the first ones to be able to solve
    these problems. Furthermore, using these flexible game solvers as a back-end,
    we implemented a tool for computing correct-by-construction controllers for stochastic
    dynamical systems under LTL specifications. Our implementations use the recent
    theoretical result that all of these games can be solved using the same symbolic
    fixpoint algorithm but utilizing different, domain specific calculations of the
    involved predecessor operators. The main feature of our toolchain is the utilization
    of two programming abstractions: one to separate the symbolic fixpoint computations
    from the predecessor calculations, and another one to allow the integration of
    different BDD libraries as back-ends. In particular, we employ a multi-threaded
    execution of the fixpoint algorithm by using the multi-threaded BDD library Sylvan,
    which leads to enormous computational savings.'

  text: 'In all state-of-the-art sketching and coreset techniques for clustering,
    as well as in the best known fixed-parameter tractable approximation algorithms,
    randomness plays a key role. For the classic k-median and k-means problems, there
    are no known deterministic dimensionality reduction procedure or coreset construction
    that avoid an exponential dependency on the input dimension d, the precision parameter
    $\varepsilon^{-1}$ or k. Furthermore, there is no coreset construction that succeeds
    with probability $1-1/n$ and whose size does not depend on the number of input
    points, n. This has led researchers in the area to ask what is the power of randomness
    for clustering sketches [Feldman WIREs Data Mining Knowl. Discov’20].Similarly,
    the best approximation ratio achievable deterministically without a complexity
    exponential in the dimension are $1+\sqrt{2}$ for k-median [Cohen-Addad, Esfandiari,
    Mirrokni, Narayanan, STOC’22] and 6.12903 for k-means [Grandoni, Ostrovsky, Rabani,
    Schulman, Venkat, Inf. Process. Lett.’22]. Those are the best results, even when
    allowing a complexity FPT in the number of clusters k: this stands in sharp contrast
    with the $(1+\varepsilon)$-approximation achievable in that case, when allowing
    randomization.In this paper, we provide deterministic sketches constructions for
    clustering, whose size bounds are close to the best-known randomized ones. We
    show how to compute a dimension reduction onto $\varepsilon^{-O(1)} \log k$ dimensions
    in time $k^{O\left(\varepsilon^{-O(1)}+\log \log k\right)}$ poly $(n d)$, and
    how to build a coreset of size $O\left(k^{2} \log ^{3} k \varepsilon^{-O(1)}\right)$
    in time $2^{\varepsilon^{O(1)} k \log ^{3} k}+k^{O\left(\varepsilon^{-O(1)}+\log
    \log k\right)}$ poly $(n d)$. In the case where k is small, this answers an open
    question of [Feldman WIDM’20] and [Munteanu and Schwiegelshohn, Künstliche Intell.
    ’18] on whether it is possible to efficiently compute coresets deterministically.We
    also construct a deterministic algorithm for computing $(1+$ $\varepsilon)$-approximation
    to k-median and k-means in high dimensional Euclidean spaces in time $2^{k^{2}
    \log ^{3} k / \varepsilon^{O(1)}}$ poly $(n d)$, close to the best randomized
    complexity of $2^{(k / \varepsilon)^{O(1)}}$ nd (see [Kumar, Sabharwal, Sen, JACM
    10] and [Bhattacharya, Jaiswal, Kumar, TCS’18]).Furthermore, our new insights
    on sketches also yield a randomized coreset construction that uses uniform sampling,
    that immediately improves over the recent results of [Braverman et al. FOCS ’22]
    by a factor k.'

  text: Pruning—that is, setting a significant subset of the parameters of a neural
    network to zero—is one of the most popular methods of model compression. Yet,
    several recent works have raised the issue that pruning may induce or exacerbate
    bias in the output of the compressed model. Despite existing evidence for this
    phenomenon, the relationship between neural network pruning and induced bias is
    not well-understood. In this work, we systematically investigate and characterize
    this phenomenon in Convolutional Neural Networks for computer vision. First, we
    show that it is in fact possible to obtain highly-sparse models, e.g. with less
    than 10% remaining weights, which do not decrease in accuracy nor substantially
    increase in bias when compared to dense models. At the same time, we also find
    that, at higher sparsities, pruned models exhibit higher uncertainty in their
    outputs, as well as increased correlations, which we directly link to increased
    bias. We propose easy-to-use criteria which, based only on the uncompressed model,
    establish whether bias will increase with pruning, and identify the samples most
    susceptible to biased predictions post-compression. Our code can be found at https://github.com/IST-DASLab/pruned-vision-model-bias.

  text: "Many coupled evolution equations can be described via 2×2-block operator
    matrices of the form A=[ \r\nA\tB\r\nC\tD\r\n ] in a product space X=X1×X2 with
    possibly unbounded entries. Here, the case of diagonally dominant block operator
    matrices is considered, that is, the case where the full operator A can be seen
    as a relatively bounded perturbation of its diagonal part with D(A)=D(A)×D(D)
    though with possibly large relative bound. For such operators the properties of
    sectoriality, R-sectoriality and the boundedness of the H∞-calculus are studied,
    and for these properties perturbation results for possibly large but structured
    perturbations are derived. Thereby, the time dependent parabolic problem associated
    with A can be analyzed in maximal Lpt\r\n-regularity spaces, and this is applied
    to a wide range of problems such as different theories for liquid crystals, an
    artificial Stokes system, strongly damped wave and plate equations, and a Keller-Segel
    model."
