  text: The first influential hypothesis for sex chromosome evolution was proposed
    in 1914 by H. J. Muller, who argued that once recombination was suppressed between
    the X and Y chromosomes, Y-linked genes become “sheltered” from selection, leading
    to accumulation of recessive loss-of-function (LOF) mutations and decay of Y-linked
    genes. The hypothesis fell out of favor in the 1970s because early mathematical
    models failed to support it and data on the dominance of lethal mutations were
    viewed as incompatible with the hypothesis. We reevaluate the main arguments against
    Muller's hypothesis and find that they do not conclusively exclude a role for
    sheltering in sex chromosome evolution. By relaxing restrictive assumptions of
    earlier models, we show that sheltering promotes fixation of LOF mutations with
    sexually dimorphic fitness effects, resulting in decay of X-linked genes that
    are exclusively expressed by males and Y-linked genes that are primarily, though
    not necessarily exclusively, expressed by females. We further show that drift
    and other processes contributing to Y degeneration (i.e. selective interference
    and regulatory evolution) expand conditions of Y-linked gene loss by sheltering.
    The actual contribution of sheltering to sex chromosome evolution hinges upon
    the distribution of dominance and sex-specific fitness effects of LOF mutations,
    which we discuss.

  text: "Traffic in datacenters may follow some pattern: some pairs of servers communicate
    more frequently than others. Demand-oblivious networks may perform poorly for
    such workloads, and demand-aware networks optimized for traffic should be used
    instead. Unfortunately, not all shapes of networks are feasible in real hardware.
    Practical limitations are usually provided in the form of a topology. For example,
    a network may be required to be a binary tree, a bounded-degree graph or a Fat
    tree.\r\nIn this work, we consider a topology of a binary tree, one of the most
    fundamental network topologies. We show that already finding an optimal demand-aware
    binary tree network is NP-hard. Then, we explore how various optimization techniques,
    including simple local searches, as well as deterministic mutation and crossover
    operators, cope with generating efficient tree networks on real-life and synthetic
    workloads."

  text: "We present the first supermartingale certificate for quantitative \r\n-regular
    properties of discrete-time infinite-state stochastic systems. Our certificate
    is defined on the product of the stochastic system and a limit-deterministic Büchi
    automaton that specifies the property of interest; hence we call it a limit-deterministic
    Büchi supermartingale (LDBSM). Previously known supermartingale certificates applied
    only to quantitative reachability, safety, or reach-avoid properties, and to qualitative
    (i.e., probability 1) \r\n-regular properties.We also present fully automated
    algorithms for the template-based synthesis of LDBSMs, for the case when the stochastic
    system dynamics and the controller can be represented in terms of polynomial inequalities.
    Our experiments demonstrate the ability of our method to solve verification and
    control tasks for stochastic systems that were beyond the reach of previous supermartingale-based
    approaches."

  text: "Game Theory is the mathematical formalization of social dynamics - systems
    where agents interact over time and the evolution of the state of the system depends
    on the decisions of every player. \r\nThis thesis takes the perspective of a single
    player and focuses on what they can guarantee in the worst case over the behavior
    of other players.\r\nIn other words, we consider that the objective of every other
    player in the game is exactly the opposite to the player.\r\nWe focus on sustained
    interactions over time, where the players repeatedly obtain quantitative rewards
    over time, and they are interested in maximizing their long-term performance.\t\r\nFormally,
    this thesis focuses on zero-sum games with the liminf average objective.\r\nTwo
    fundamental questions that Game Theory aims to answer are the following.\r\n\r\n1.
    How much can a player guarantee to obtain after the interaction?\r\n\r\n2. How
    to act in order to obtain the previously mentioned guarantee?\r\n\r\nThese questions
    are formalized by the concepts of \"value\" and \"optimal strategies\". \t\r\nWe
    study their properties on games that exhibit one or more of the following properties.
    \r\n\r\n1. Partial Observation: \r\nthe players can not perfectly observe the
    current state of the system during the game. We consider the model of (finite)
    Partially Observable Markov Decision Processes and prove that finite-memory strategies
    are sufficient to approximately guarantee the value.\r\n\r\n2. Perturbed Description:
    \r\nthe formal description of the game is perturbed by a small parameter.\r\nWe
    consider the model of (finite) Perturbed Matrix Games, and provide algorithms
    to check various robustness properties and to compute the parameterized value
    and optimal strategies.\r\n\r\n3. Stochastic Transitions: \r\nthe actions of the
    players determine the behavior of the evolution of the system, described as a
    probability distribution over the next state.\r\nWe consider the model of (finite)
    Perturbed Stochastic Games and provide formulas for the marginal value.\r\n\r\n4.
    Infinite States: \r\nthe system can be in infinitely many states.\r\nWe consider
    the model of Random Dynamic Games on a class of infinite graphs, prove the existence
    of the value, and quantify the concentration of finite-horizon values."

  text: We develop a heuristic for the density of integer points on affine cubic surfaces.
    Our heuristic applies to smooth surfaces defined by cubic polynomials that are
    log K3, but it can also be adjusted to handle singular cubic surfaces. We compare
    our heuristic to Heath-Brown’s prediction for sums of three cubes, as well as
    to asymptotic formulae in the literature around Zagier’s work on the Markoff cubic
    surface, and work of Baragar and Umeda on further surfaces of Markoff-type. We
    also test our heuristic against numerical data for several families of cubic surfaces.
acknowledgement: "The authors owe a debt of thanks to Yonatan Harpaz for asking about
  circle method heuristics for log K3 surfaces. His contribution to the resulting
  discussion is gratefully acknowledged. Thanks are also due to Andrew Sutherland
  for help with numerical data for the equation x^3 + y^3 + z^3 = 1, together with
  Alex Gamburd, Amit Ghosh, Peter Sarnak and Matteo Verzobio for their interest in
  this paper. Special thanks are due to Victor Wang for helpful conversations about
  the circle method heuristics and to the anonymous referee for several useful comments.

  text: "Population III stars are possible precursors to early supermassive black
    holes (BHs). The presence of soft UV Lyman–Werner (LW) background radiation can
    suppress Population III star formation in minihaloes and allow them to form in
    pristine atomic-cooling haloes. In the absence of molecular hydrogen (⁠H2⁠) cooling,
    atomic-cooling haloes enable rapid collapse with suppressed fragmentation. High
    background LW fluxes from preceding star-formation have been proposed to dissociate
    H2⁠. This flux can be supplemented by LW radiation from one or more Population
    III star(s) in the same halo, reducing the necessary background level. Here, we
    consider atomic-cooling haloes in which multiple protostellar cores form close
    to one another nearly simultaneously. We assess whether the first star’s LW radiation
    can dissociate nearby \r\n⁠, enabling rapid accretion on to a nearby protostellar
    core, and the prompt formation of a second, supermassive star (SMS) from warm,
    atomically-cooled gas. We use a set of hydrodynamical simulations with the code
    enzo, with identical LW backgrounds centred on a halo with two adjacent collapsing
    gas clumps. When an additional large local LW flux is introduced, we observe immediate
    reductions in both the accretion rates and the stellar masses that form within
    these clumps. While the LW flux reduces the H2 fraction and increases the gas
    temperature, the halo core’s potential well is too shallow to promptly heat the
    gas to >1000 K and increase the second protostar’s accretion rate. We conclude
    that this internal LW feedback scenario is unlikely to facilitate SMS or massive
    BH seed formation."

  text: Zirconia nanocrystals (ZrO2 NCs) are a stable host material for lanthanides,
    but their performance lags behind that of the leading NaYF4 nanomaterials. Here,
    we leverage surface chemistry and core/shell architectures to uncover the contribution
    of dopants at the nanocrystal surface and of dopants in the nanocrystal bulk.
    We first assess the doping efficiency by ICP and find that, while Eu is almost
    quantitatively incorporated, the other lanthanides (La, Ce, Tb, Tm, Er, Yb) have
    about 50% incorporation efficiency over the studied doping range of 1–10%. We
    then determine the nanocrystal surface chemistry using NMR spectroscopy, despite
    the additional spectral line broadening caused by the paramagnetic lanthanide
    dopants. By varying the surface ligands and measuring the photoluminescence, we
    resolve the spectroscopic signals that are sensitive to a change in surface chemistry.
    Time-resolved emission spectra further reinforce the notion of a bulk component
    with a long luminescent lifetime and a surface component with a fast lifetime.
    Upon shelling Eu- or Tb-doped zirconia NCs with pure zirconia, the surface component
    disappears, and the photoluminescence quantum yield increases. We further functionalized
    the surface of the core/shell particles with oleylphosphonic acid ligands to obtain
    excellent dispersibility. These results show that lanthanide-doped zirconia NCs
    can be engineered to eliminate deactivation pathways.

  text: "A quantitative word automaton (QWA) defines a function from infinite words
    to values. For example, every infinite run of a limit-average QWA \U0001D49C obtains
    a mean payoff, and every word w ∈ Σ^ω is assigned the maximal mean payoff obtained
    by nondeterministic runs of \U0001D49C over w. We introduce quantitative language
    automata (QLAs) that define functions from language generators (i.e., implementations)
    to values, where a language generator can be nonprobabilistic, defining a set
    of infinite words, or probabilistic, defining a probability measure over infinite
    words. A QLA consists of a QWA and an aggregator function. For example, given
    a QWA \U0001D49C, the infimum aggregator maps each language L ⊆ Σ^ω to the greatest
    lower bound assigned by \U0001D49C to any word in L. For boolean value sets, QWAs
    define boolean properties of traces, and QLAs define boolean properties of sets
    of traces, i.e., hyperproperties. For more general value sets, QLAs serve as a
    specification language for a generalization of hyperproperties, called quantitative
    hyperproperties. A nonprobabilistic (resp. probabilistic) quantitative hyperproperty
    assigns a value to each set (resp. distribution) G of traces, e.g., the minimal
    (resp. expected) average response time exhibited by the traces in G. We give several
    examples of quantitative hyperproperties and investigate three paradigmatic problems
    for QLAs: evaluation, nonemptiness, and universality. In the evaluation problem,
    given a QLA \U0001D538 and an implementation G, we ask for the value that \U0001D538
    assigns to G. In the nonemptiness (resp. universality) problem, given a QLA \U0001D538
    and a value k, we ask whether \U0001D538 assigns at least k to some (resp. every)
    language. We provide a comprehensive picture of decidability for these problems
    for QLAs with common aggregators as well as their restrictions to ω-regular languages
    and trace distributions generated by finite-state Markov chains."

  text: 'We examine population structures for their ability to maintain diversity
    in neutral evolution. We use the general framework of evolutionary graph theory
    and consider birth–death (bd) and death–birth (db) updating. The population is
    of size N. Initially all individuals represent different types. The basic question
    is: what is the time TN until one type takes over the population? This time is
    known as consensus time in computer science and as total coalescent time in evolutionary
    biology. For the complete graph, it is known that TN is quadratic in N for db
    and bd. For the cycle, we prove that TN is cubic in N for db and bd. For the star,
    we prove that TN is cubic for bd and quasilinear (N log N) for db. For the double
    star, we show that TN is quartic for bd. We derive upper and lower bounds for
    all undirected graphs for bd and db. We also show the Pareto front of graphs (of
    size N = 8) that maintain diversity the longest for bd and db. Further, we show
    that some graphs that quickly homogenize can maintain high levels of diversity
    longer than graphs that slowly homogenize. For directed graphs, we give simple
    contracting star-like structures that have superexponential time scales for maintaining
    diversity.'

  text: With stunning clarity, the JWST has revealed the Universe’s first billion
    years. The scientific community is analysing a wealth of JWST imaging and spectroscopic
    data from that era, and is in the process of rewriting the astronomy textbooks.
    Here, as a result of the 2024 ISSI Breakthrough Workshop, we provide a snapshot
    of the great progress made towards understanding the initial chapters of our cosmic
    history 1.5 years into the JWST science mission. We present the current census
    of early galaxies, their luminosities, appearance, chemical composition, masses
    and formation histories as revealed by JWST. We relate the discovery of massive
    black holes in early galaxies and discuss their demographics and implications
    for their formations and growth. We conclude by describing the potential sources
    of reionization and our current understanding of how the Universe became fully
    ionized. Throughout the Perspective, we highlight discoveries and breakthroughs,
    topics and issues that are not yet understood, and questions that will be addressed
    in the coming years, as JWST continues its revolutionary observations of the early
    Universe.
acknowledgement: While this Perspective is written by a small number of authors, invited
  to ISSI Bern in March 2024 as part of the 2024 ISSI Breakthrough Workshop, we acknowledge
  the work of a large community that is advancing our collective understanding of
  the evolution of the early Universe. We thank ISSI for sponsoring the 2024 Breakthrough
  Workshop, and the ISSI staff for their wonderful welcome and support. We are grateful
  to the author collaborators, who made this paper possible. Collectively, we are
  grateful to the large group of committed scientists and engineers, worldwide, who
  designed, built and commissioned the JWST and made a decades-long astronomer dream
  a reality. R.P.N. is a NASA Hubble Fellow. We are grateful to M. Dickinson for a
  careful read of the final paper and to F. Crameri (ISSI) for his expert help designing
  the very best figures. We dedicate this paper to the 20,000 people who spent decades
  to make JWST an incredible discovery machine.

  text: We study the problem of predictive runtime monitoring of black-box dynamical
    systems with quantitative safety properties. The black-box setting stipulates
    that the exact semantics of the dynamical system and the controller are unknown,
    and that we are only able to observe the state of the controlled (aka, closed-loop)
    system at finitely many time points. We present a novel framework for predicting
    future states of the system based on the states observed in the past. The numbers
    of past states and of predicted future states are parameters provided by the user.
    Our method is based on a combination of Taylor’s expansion and the backward difference
    operator for numerical differentiation. We also derive an upper bound on the prediction
    error under the assumption that the system dynamics and the controller are smooth.
    The predicted states are then used to predict safety violations ahead in time.
    Our experiments demonstrate practical applicability of our method for complex
    black-box systems, showing that it is computationally lightweight and yet significantly
    more accurate than the state-of-the-art predictive safety monitoring techniques.

  text: The specific introduction of ^1H-^13C or ^1H-^15N moieties into otherwise
    deuterated proteins holds great potential for high-resolution solution and magic-angle
    spinning (MAS) NMR studies of protein structure and dynamics. Arginine residues
    play key roles for example at active sites of enzymes. Taking advantage of a chemically
    synthesized Arg with a ^13C-^1H2 group in an otherwise deuterated backbone, we
    demonstrate here the usefulness of proton-detected MAS NMR approaches to probe
    arginine dynamics. In experiments with crystalline ubiquitin and the 134 kDa tetrameric
    enzyme malate dehydrogenase we detected a wide range of motions, from sites that
    are rigid on time scales of at least tens of milliseconds to residues undergoing
    predominantly nanosecond motions. Spin-relaxation and dipolar-coupling measurements
    enabled quantitative determination of these dynamics. We observed microsecond
    dynamics of residue Arg54 in crystalline ubiquitin, whose backbone is known to
    sample different β-turn conformations on this time scale. The labeling scheme
    and experiments presented here expand the toolkit for high-resolution proton-detected
    MAS NMR.

  text: Cell migration in narrow microenvironments occurs in numerous physiological
    processes. It involves successive cycles of confinement and release that drive
    important morphological changes. However, it remains unclear whether migrating
    cells can retain a memory of their past morphological states that could potentially
    facilitate their navigation through confined spaces. We demonstrate that local
    geometry governs a switch between two cell morphologies, thereby facilitating
    cell passage through long and narrow gaps. We combined cell migration assays on
    standardized microsystems with biophysical modelling and biochemical perturbations
    to show that migrating cells have a long-term memory of past confinement events.
    The morphological cell states correlate across transitions through actin cortex
    remodelling. These findings indicate that mechanical memory in migrating cells
    plays an active role in their migratory potential in confined environments.

  text: The medial axis of a set consists of the points in the ambient space without
    a unique closest point in the original set. Since its introduction, the medial
    axis has been used extensively in many applications as a method of computing a
    skeleton topologically equivalent to the original set. Unfortunately, one limiting
    factor in the use of the medial axis of a smooth manifold is that it is not necessarily
    topologically stable under small perturbations of the manifold. To counter these
    instabilities, various prunings of the medial axis have been proposed in the computational
    geometry community. Here, we examine one type of pruning, called burning. Because
    of the good experimental results it was hoped that the burning method of simplifying
    the medial axis would be stable. In this work, we show a simple example that dashes
    such hopes. Based on Bing’s house with two rooms, we demonstrate an isotopy of
    a shape where the medial axis goes from collapsible to non-collapsible. More precisely,
    we consider the standard deformation retract from the closed ball to Bing’s house
    with two rooms, but stop just short of the point where Bing’s house becomes two
    dimensional. This way we obtain an isotopy from the 3-ball to a thickened version
    of Bing’s house. Under this isotopy, the medial axis goes from collapsible to
    non-collapsible. We stress that this isotopy can be made generic, in the sense
    of singularity theory, as developed by Arnol’d and Thom.

  text: "Complex 3D shapes can be created by morphing flat 2D configurations. Such
    deformations\r\neither preserve the intrinsic material geometry (e.g., folding

    shape can be further controlled to achieve a\r\ntarget functionality. A key challenge
    is to take the material specifications and the actuation\r\nprocess as input to
    automatically design the target 3D shape and its functionality. This thesis\r\npresents
    two novel computational pipelines for the design and control of shape-morphing\r\nstructures
    used to create functional prototypes.\r\nThe first pipeline borrows from the art
    of origami to fold paper into intricate shapes and\r\napplies this principle to
    make 3D lighting displays. We introduce, PCBend a computational\r\ndesign approach
    that covers a surface with individually addressable RGB LEDs, effectively\r\nforming
    a low-resolution surface by folding rigid printed circuit boards (PCBs). We optimize\r\ncut
    patterns on PCBs to act as hinges and co-design LED placement, circuit routing,
    and\r\nfabrication constraints to produce PCB blueprints. The PCBs are fabricated
    using automated\r\nstandard manufacturing services with LEDs embedded on them.
    Finally, the fabricated PCBs\r\nare cut along the contour and folded onto a 3D-printed
    support. The 3D lighting display is\r\nthen controlled to display complex surface
    light patterns.\r\nCreating 3D shapes through folding is only possible if their
    planar configuration, called ”unfolding” exists without any distortion or overlap.
    Existing methods often permit distortion\r\nor require multiple patches, which
    are unsuitable for fabrication pipelines that rely on folding\r\nnon-stretchable
    materials. We reinforce such fabrication pipelines by providing a geometric\r\nrelaxation
    to the problem, where the input shape is modified to admit overlap-free unfolding.\r\nThe
    second fabrication pipeline extends shape morphing to soft robotics by emulating
    nature’s\r\nblueprint of distributed actuation. Inspired by vertebrates, we build
    musculoskeletal robots\r\nusing modular active actuators, employing Liquid Crystal
    Elastomers (LCEs) as shrinkable\r\nartificial muscles integrated with 3D-printed
    bones. The chemical composition of LCEs is\r\naltered to enable untethered actuation
    through infrared radiation, allowing active control of\r\nindividual muscles and
    their corresponding bones. The combined motion of individual bones\r\ndefines
    the robot’s overall shape and functionality. Our proposed system significantly
    expands\r\nboth the design and control spaces of soft robots, which we harness
    using our computational\r\ndesign tools. We build several physical robots that
    exhibit complex shape morphing and varied\r\nterrain navigation, showcasing the
    versatility of our pipeline.\r\nThis thesis explores applications ranging from
    intricate light patterns displayed on 3D shapes\r\nformed by folding rigid PCBs
    to untethered robots that use contractile muscles to exhibit\r\nshape morphing
    and locomotion. Through these examples, the thesis highlights how computational
    design and distributed actuation, integrated with novel materials, can transform\r\npassive
    structures into functional prototypes."

  text: "Natural organisms utilize distributed actuation through their musculoskeletal\r\nsystems
    to adapt their gait for traversing diverse terrains or to morph their\r\nbodies
    for varied tasks. A longstanding challenge in robotics is to emulate\r\nthis capability
    of natural organisms, which has motivated the development of\r\nnumerous soft
    robotic systems. However, such systems are generally optimized\r\nfor a single
    functionality, lack the ability to change form or function on\r\ndemand, or remain
    tethered to bulky control systems. To address these\r\nlimitations, we present
    a framework for designing and controlling robots that\r\nutilize distributed actuation.
    We propose a novel building block that\r\nintegrates 3D-printed bones with liquid
    crystal elastomer (LCE) muscles as\r\nlightweight actuators, enabling the modular
    assembly of musculoskeletal robots.\r\nWe developed LCE rods that contract in
    response to infrared radiation, thereby\r\nproviding localized, untethered control
    over the distributed skeletal network\r\nand producing global deformations of
    the robot. To fully capitalize on the\r\nextensive design space, we introduce
    two computational tools: one for\r\noptimizing the robot's skeletal graph to achieve
    multiple target deformations,\r\nand another for co-optimizing skeletal designs
    and control gaits to realize\r\ndesired locomotion. We validate our framework
    by constructing several robots\r\nthat demonstrate complex shape morphing, diverse
    control schemes, and\r\nenvironmental adaptability. Our system integrates advances
    in modular material\r\nbuilding, untethered and distributed control, and computational
    design to\r\nintroduce a new generation of robots that brings us closer to the
    capabilities\r\nof living organisms."

  text: Cell and tissue movement in development, cancer invasion, and immune response
    relies on chemical or mechanical guidance cues. In many systems, this behavior
    is locally directed by self-generated signaling gradients rather than long-range,
    prepatterned cues. However, how heterogeneous mixtures of cells interact nonreciprocally
    and navigate through self-generated gradients remains largely unexplored. Here,
    we introduce a theoretical framework for the self-organized chemotaxis of heterogeneous
    cell populations. We find that the relative chemotactic sensitivities of different
    cell populations control their long-time coupling and comigration dynamics, with
    boundary conditions such as external cell and attractant reservoirs substantially
    influencing the migration patterns. Our model predicts an optimal parameter regime
    that enables robust and colocalized migration. We test our theoretical predictions
    with in vitro experiments demonstrating the comigration of distinct immune cell
    populations, and quantitatively reproduce observed migration patterns under wild-type
    and perturbed conditions. Interestingly, immune cell comigration occurs close
    to the predicted optimal regime. Finally, we incorporate mechanical interactions
    into our framework, revealing a nontrivial interplay between chemotactic and mechanical
    nonreciprocity in driving collective migration. Together, our findings suggest
    that self-generated chemotaxis is a robust strategy for the navigation of mixed
    cell populations.

  text: 'We consider equilibria in multiplayer stochastic graph games with terminal-node
    rewards. In such games, Nash equilibria are defined assuming that each player
    seeks to maximise their expected payoff, ignoring their aversion or tolerance
    to risk. We therefore study risk-sensitive equilibria (RSEs), where the expected
    payoff is replaced by a risk measure. A classical risk measure in the literature
    is the entropic risk measure, where each player has a real valued parameter capturing
    their risk-averseness. We introduce the extreme risk measure, which corresponds
    to extreme cases of entropic risk measure, where players are either extreme optimists
    or extreme pessimists. Under extreme risk measure, every player is an extremist:
    an extreme optimist perceives their reward as the maximum payoff that can be achieved
    with positive probability, while an extreme pessimist expects the minimum payoff
    achievable with positive probability. We argue that the extreme risk measure,
    especially in multi-player graph based settings, is particularly relevant as they
    can model several real life instances such as interactions between secure systems
    and potential security threats, or distributed controls for safety critical systems.
    We prove that RSEs defined with the extreme risk measure are guaranteed to exist
    when all rewards are non-negative. Furthermore, we prove that the problem of deciding
    whether a given game contains an RSE that generates risk measures within specified
    intervals is decidable and NP-complete for our extreme risk measure, and even
    PTIME-complete when all players are extreme optimists, while that same problem
    is undecidable using the entropic risk measure or even the classical expected
    payoff. This establishes, to our knowledge, the first decidable fragment for equilibria
    in simple stochastic games without restrictions on strategy types or number of
    players.'
