  text: Iran employs one of the most prominent Internet censors in the world. An important
    part of Iran’s censorship apparatus is its analysis of unencrypted protocols such
    as HTTP and DNS. During routine evaluations of Iran’s HTTP and DNS censorship,
    we noticed several properties we believe to be unknown today. For instance, we
    found injections of correct static IPs for some domains such as google.com on
    the DNS level, unclear HTTP version parsing, and correlations between DNS and
    HTTP censorship. In this paper, we present our findings to the community and discuss
    possible takeaways for affected people and the censorship circumvention community.
    As some of our findings left us bewildered, we hope to ignite a discussion about
    Iran’s censorship behavior. We aim to use the discussion of our work to execute
    a thorough analysis and explanation of Iran’s censorship behavior in the future.

  text: 'Censors have long censored Transport Layer Security (TLS) traffic by inspecting
    the domain name in the unencrypted Server Name Indication (SNI) extension. By
    encrypting the SNI extension, the Encrypted ClientHello (ECH) prevents censors
    from blocking TLS traffic to certain domains. Despite this promising outlook,
    ECH’s current capability to contest TLS censorship is unclear; for instance, Russia
    has started censoring ECH connections successfully. This paper clarifies ECH’s
    current role for TLS censorship. To this end, we evaluate servers’ support for
    ECH and its analysis and subsequent blocking by censors. We determine Cloudflare
    as the only major provider supporting ECH. Additionally, we affirm previously
    known ECH censorship in Russia and uncover indirect censorship of ECH through
    encrypted DNS censorship in China and Iran. Our findings suggest that ECH’s contribution
    to censorship circumvention is currently limited: we consider ECH’s dependence
    on encrypted DNS especially challenging for ECH’s capability to circumvent censorship.
    We stress the importance of censorship-resistant ECH to solve the long-known problem
    of SNI-based TLS censorship.'

  text: Basado en una encuesta en línea efectuada a futuros docentes en Badajoz (España)
    y Posadas (Argentina), el presente artículo explora competencias multilingües
    y formas de educación intercultural más allá de las fronteras nacionales. Los
    datos cuantitativos obtenidos demuestran que, en ambas ciudades, la gran mayoría
    de los futuros docentes considera que los conocimientos sobre sistemas educativos
    de otros países, la inclusión de recursos didácticos bi- o multilingües y la inclusión
    de temas interculturales son importantes o muy importantes. Además, muchos de
    los futuros profesionales de la educación cuentan con capital intercultural que
    se podría aplicar en diferentes contextos nacionales y transnacionales de enseñanza
    y aprendizaje interculturales. Sin embargo, para poder aprovechar plenamente su
    potencial, es crucial crear contextos educativos más equitativos e incluyentes
    que traten de superar los desequilibrios sistemáticos en las oportunidades de
    realización del capital intercultural.

  text: We investigate the impact of Brexit on the corporate bond market by analyzing
    a comprehensive database covering corporate bond listings on European and UK trading
    venues. We find a significant shift in bond market activity, evidenced by a 49%
    increase in the number of bond listings in the EEA30 countries relative to the
    UK market after Brexit. Country-level analyses reveal a staggered effect on market
    activity, with predominantly international issuers adjusting their bond listings
    between the initially scheduled Brexit date and the final withdrawal date. At
    the issuer level, our findings indicate that the relative attractiveness of the
    EEA30 market has increased post-Brexit. Overall, these results suggest that the
    European capital market has successfully adapted to the loss of its largest financial
    center and exhibits a rising corporate bond market activity.

  text: 'Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two
    separate mechanisms: (a) the injection/ejection of charge carriers across the
    Schottky barrier formed at the (metal-)electrode-DW junction and (b) the transport
    of those charge carriers along the DW. Current-voltage (I-U) characteristics,
    recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate
    between these two contributions. Practically, they allow us to directly quantify
    the physical parameters relevant to the two mechanisms (a) and (b) mentioned above.
    These are, for example, the resistance of the DW, the saturation current, the
    ideality factor, and the Schottky barrier height of the electrode-DW junction.
    Furthermore, the activation energies needed to initiate the thermally activated
    electronic transport along the DWs can be extracted. In addition, we show that
    electronic transport along LNO DWs can be elegantly viewed and interpreted in
    an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit
    model, the R2D2 model. Finally, our R2D2 model was checked for its universality
    by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally
    of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature.'

  text: "We rigorously derive novel and sharp finite-data error bounds for highly\r\nsample-efficient
    Extended Dynamic Mode Decomposition (EDMD) for both i.i.d. and\r\nergodic sampling.
    In particular, we show all results in a very general setting\r\nremoving most
    of the typically imposed assumptions such that, among others,\r\ndiscrete- and
    continuous-time stochastic processes as well as nonlinear partial\r\ndifferential
    equations are contained in the considered system class. Besides\r\nshowing an
    exponential rate for i.i.d. sampling, we prove, to the best of our\r\nknowledge,
    the first superlinear convergence rates for ergodic sampling of\r\ndeterministic
    systems. We verify sharpness of the derived error bounds by\r\nconducting numerical
    simulations for highly-complex applications from molecular\r\ndynamics and chaotic
    flame propagation."

  text: We derive efficient algorithms to compute weakly Pareto optimal solutions
    for smooth, convex and unconstrained multiobjective optimization problems in general
    Hilbert spaces. To this end, we define a novel inertial gradient-like dynamical
    system in the multiobjective setting, which trajectories converge weakly to Pareto
    optimal solutions. Discretization of this system yields an inertial multiobjective
    algorithm which generates sequences that converge weakly to Pareto optimal solutions.
    We employ Nesterov acceleration to define an algorithm with an improved convergence
    rate compared to the plain multiobjective steepest descent method (Algorithm 1).
    A further improvement in terms of efficiency is achieved by avoiding the solution
    of a quadratic subproblem to compute a common step direction for all objective
    functions, which is usually required in first-order methods. Using a different
    discretization of our inertial gradient-like dynamical system, we obtain an accelerated
    multiobjective gradient method that does not require the solution of a subproblem
    in each step (Algorithm 2). While this algorithm does not converge in general,
    it yields good results on test problems while being faster than standard steepest
    descent.

  text: The efficient optimization method for locally Lipschitz continuous multiobjective
    optimization problems from [1] is extended from finite-dimensional problems to
    general Hilbert spaces. The method iteratively computes Pareto critical points,
    where in each iteration, an approximation of the subdifferential is computed in
    an efficient manner and then used to compute a common descent direction for all
    objective functions. To prove convergence, we present some new optimality results
    for nonsmooth multiobjective optimization problems in Hilbert spaces. Using these,
    we can show that every accumulation point of the sequence generated by our algorithm
    is Pareto critical under common assumptions. Computational efficiency for finding
    Pareto critical points is numerically demonstrated for multiobjective optimal
    control of an obstacle problem.

  text: We present a convolutional framework which significantly reduces the complexity
    and thus, the computational effort for distributed reinforcement learning control
    of dynamical systems governed by partial differential equations (PDEs). Exploiting
    translational equivariances, the high-dimensional distributed control problem
    can be transformed into a multi-agent control problem with many identical, uncoupled
    agents. Furthermore, using the fact that information is transported with finite
    velocity in many cases, the dimension of the agents’ environment can be drastically
    reduced using a convolution operation over the state space of the PDE, by which
    we effectively tackle the curse of dimensionality otherwise present in deep reinforcement
    learning. In this setting, the complexity can be flexibly adjusted via the kernel
    width or by using a stride greater than one (meaning that we do not place an actuator
    at each sensor location). Moreover, scaling from smaller to larger domains – or
    the transfer between different domains – becomes a straightforward task requiring
    little effort. We demonstrate the performance of the proposed framework using
    several PDE examples with increasing complexity, where stabilization is achieved
    by training a low-dimensional deep deterministic policy gradient agent using minimal
    computing resources.
