  text: In this paper we consider the stochastic primitive equation for geophysical
    flows subject to transport noise and turbulent pressure. Admitting very rough
    noise terms, the global existence and uniqueness of solutions to this stochastic
    partial differential equation are proven using stochastic maximal L² regularity,
    the theory of critical spaces for stochastic evolution equations, and global a
    priori bounds. Compared to other results in this direction, we do not need any
    smallness assumption on the transport noise which acts directly on the velocity
    field and we also allow rougher noise terms. The adaptation to Stratonovich type
    noise and, more generally, to variable viscosity and/or conductivity are discussed
    as well.

  text: Coherent flows of self-propelled particles are characterized by vortices and
    jets that sustain chaotic flows, referred to as active turbulence. Here, we reveal
    a crossover between defect-free active turbulence and active turbulence laden
    with topological defects. Interestingly, we show that concurrent to the crossover
    from defect-free to defect-laden active turbulence is the restoration of the previously
    broken SO(2) symmetry signaled by the fast decay of the two-point correlations.
    By stability analyses of the topological charge density field, we provide theoretical
    insights on the criterion for the crossover to the defect-laden active turbulent
    state. Despite the distinct symmetry features between these two active turbulence
    regimes, the flow fluctuations exhibit universal statistical scaling behaviors
    at large scales, while the spectrum of polarity fluctuations decays exponentially
    at small length scales compared to the active energy injection length. These findings
    reveal a dynamical crossover between distinct spatiotemporal organization patterns
    in polar active matter.

  text: In this paper, we study the eigenvalues and eigenvectors of the spiked invariant
    multiplicative models when the randomness is from Haar matrices. We establish
    the limits of the outlier eigenvalues λˆi and the generalized components (⟨v,uˆi⟩
    for any deterministic vector v) of the outlier eigenvectors uˆi with optimal convergence
    rates. Moreover, we prove that the non-outlier eigenvalues stick with those of
    the unspiked matrices and the non-outlier eigenvectors are delocalized. The results
    also hold near the so-called BBP transition and for degenerate spikes. On one
    hand, our results can be regarded as a refinement of the counterparts of [12]
    under additional regularity conditions. On the other hand, they can be viewed
    as an analog of [34] by replacing the random matrix with i.i.d. entries with Haar
    random matrix.

  text: "We revisit two basic Direct Simulation Monte Carlo Methods to model aggregation
    kinetics and extend them for aggregation processes with collisional fragmentation
    (shattering). We test the performance and accuracy of the extended methods and
    compare their performance with efficient deterministic finite-difference method
    applied to the same model. We validate the stochastic methods on the test problems
    and apply them to verify the existence of oscillating regimes in the aggregation-fragmentation
    kinetics recently detected in deterministic simulations. We confirm the emergence
    of steady oscillations of densities in such systems and prove the stability of
    the\r\noscillations with respect to fluctuations and noise."

  text: In the class of strictly convex smooth boundaries each of which has no strip
    around its boundary foliated by invariant curves, we prove that the Taylor coefficients
    of the “normalized” Mather’s β-function are invariant under C∞-conjugacies. In
    contrast, we prove that any two elliptic billiard maps are C0-conjugate near their
    respective boundaries, and C∞-conjugate, near the boundary and away from a line
    passing through the center of the underlying ellipse. We also prove that, if the
    billiard maps corresponding to two ellipses are topologically conjugate, then
    the two ellipses are similar.

  text: ESCRT-III filaments are composite cytoskeletal polymers that can constrict
    and cut cell membranes from the inside of the membrane neck. Membrane-bound ESCRT-III
    filaments undergo a series of dramatic composition and geometry changes in the
    presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the
    membrane morphology. We set out to understand the physical mechanisms involved
    in translating the changes in ESCRT-III polymer composition into membrane deformation.
    We have built a coarse-grained model in which ESCRT-III polymers of different
    geometries and mechanical properties are allowed to copolymerise and bind to a
    deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific
    polymers, we identify mechanical regimes in which changes in filament composition
    trigger the associated membrane transition from a flat to a buckled state, and
    then to a tubule state that eventually undergoes scission to release a small cargo-loaded
    vesicle. We then characterise how the location and kinetics of polymer loss affects
    the extent of membrane deformation and the efficiency of membrane neck scission.
    Our results identify the near-minimal mechanical conditions for the operation
    of shape-shifting composite polymers that sever membrane necks.

  text: Models of transcriptional regulation that assume equilibrium binding of transcription
    factors have been less successful at predicting gene expression from sequence
    in eukaryotes than in bacteria. This could be due to the non-equilibrium nature
    of eukaryotic regulation. Unfortunately, the space of possible non-equilibrium
    mechanisms is vast and predominantly uninteresting. The key question is therefore
    how this space can be navigated efficiently, to focus on mechanisms and models
    that are biologically relevant. In this review, we advocate for the normative
    role of theory—theory that prescribes rather than just describes—in providing
    such a focus. Theory should expand its remit beyond inferring mechanistic models
    from data, towards identifying non-equilibrium gene regulatory schemes that may
    have been evolutionarily selected, despite their energy consumption, because they
    are precise, reliable, fast, or otherwise outperform regulation at equilibrium.
    We illustrate our reasoning by toy examples for which we provide simulation code.

  text: We report frictional drag reduction and a complete flow relaminarization of
    elastic turbulence (ET) at vanishing inertia in a viscoelastic channel flow past
    an obstacle. We show that the intensity of the observed elastic waves and wall-normal
    vorticity correlate well with the measured drag above the onset of ET. Moreover,
    we find that the elastic wave frequency grows with the Weissenberg number, and
    at sufficiently high frequency it causes a decay of the elastic waves, resulting
    in ET attenuation and drag reduction. Thus, this allows us to substantiate a physical
    mechanism, involving the interaction of elastic waves with wall-normal vorticity
    fluctuations, leading to the drag reduction and relaminarization phenomena at
    low Reynolds number.

  text: 'In repeated interactions, players can use strategies that respond to the
    outcome of previous rounds. Much of the existing literature on direct reciprocity
    assumes that all competing individuals use the same strategy space. Here, we study
    both learning and evolutionary dynamics of players that differ in the strategy
    space they explore. We focus on the infinitely repeated donation game and compare
    three natural strategy spaces: memory-1 strategies, which consider the last moves
    of both players, reactive strategies, which respond to the last move of the co-player,
    and unconditional strategies. These three strategy spaces differ in the memory
    capacity that is needed. We compute the long term average payoff that is achieved
    in a pairwise learning process. We find that smaller strategy spaces can dominate
    larger ones. For weak selection, unconditional players dominate both reactive
    and memory-1 players. For intermediate selection, reactive players dominate memory-1
    players. Only for strong selection and low cost-to-benefit ratio, memory-1 players
    dominate the others. We observe that the supergame between strategy spaces can
    be a social dilemma: maximum payoff is achieved if both players explore a larger
    strategy space, but smaller strategy spaces dominate.'

  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.
