  text: <jats:p>The reduction of high-dimensional systems to effective models on a
    smaller set of variables is an essential task in many areas of science. For stochastic
    dynamics governed by diffusion processes, a general procedure to find effective
    equations is the conditioning approach. In this paper, we are interested in the
    spectrum of the generator of the resulting effective dynamics, and how it compares
    to the spectrum of the full generator. We prove a new relative error bound in
    terms of the eigenfunction approximation error for reversible systems. We also
    present numerical examples indicating that, if Kramers–Moyal (KM) type approximations
    are used to compute the spectrum of the reduced generator, it seems largely insensitive
    to the time window used for the KM estimators. We analyze the implications of
    these observations for systems driven by underdamped Langevin dynamics, and show
    how meaningful effective dynamics can be defined in this setting.</jats:p>

  text: Gaussian-beam-like bundles of semi-guided waves propagating in a dielectric
    slab can excite modes with high-order optical angular momentum supported by a
    circular fiber. We consider a multimode step-index fiber with a high-index coating,
    where the waves in the slab are evanescently coupled to the modes of the fiber.
    Conditions for effective resonant interaction are identified. Based on a hybrid
    analytical–numerical coupled mode model, our simulations predict that substantial
    fractions of the input power can be focused into waves with specific orbital angular
    momentum, of excellent purity, with a clear distinction between degenerate modes
    with opposite vorticity.

  text: "We construct more efficient cryptosystems with provable\r\nsecurity against
    adaptive attacks, based on simple and natural hardness\r\nassumptions in the standard
    model. Concretely, we describe:\r\n– An adaptively-secure variant of the efficient,
    selectively-secure LWE-\r\nbased identity-based encryption (IBE) scheme of Agrawal,
    Boneh,\r\nand Boyen (EUROCRYPT 2010). In comparison to the previously\r\nmost
    efficient such scheme by Yamada (CRYPTO 2017) we achieve\r\nsmaller lattice parameters
    and shorter public keys of size O(log λ),\r\nwhere λ is the security parameter.\r\n–
    Adaptively-secure variants of two efficient selectively-secure pairing-\r\nbased
    IBEs of Boneh and Boyen (EUROCRYPT 2004). One is based\r\non the DBDH assumption,
    has the same ciphertext size as the cor-\r\nresponding BB04 scheme, and achieves
    full adaptive security with\r\npublic parameters of size only O(log λ). The other
    is based on a q-\r\ntype assumption and has public key size O(λ), but a ciphertext
    is\r\nonly a single group element and the security reduction is quadrat-\r\nically
    tighter than the corresponding scheme by Jager and Kurek\r\n(ASIACRYPT 2018).\r\n–
    A very efficient adaptively-secure verifiable random function where\r\nproofs,
    public keys, and secret keys have size O(log λ).\r\nAs a technical contribution
    we introduce blockwise partitioning, which\r\nleverages the assumption that a
    cryptographic hash function is weak\r\nnear-collision resistant to prove full
    adaptive security of cryptosystems."

  text: "Verifiable random functions (VRFs), introduced by Micali,\r\nRabin and Vadhan
    (FOCS’99), are the public-key equivalent of pseudo-\r\nrandom functions. A public
    verification key and proofs accompanying the\r\noutput enable all parties to verify
    the correctness of the output. How-\r\never, all known standard model VRFs have
    a reduction loss that is much\r\nworse than what one would expect from known optimal
    constructions of\r\nclosely related primitives like unique signatures. We show
    that:\r\n1. Every security proof for a VRF that relies on a non-interactive\r\nassumption
    has to lose a factor of Q, where Q is the number of adver-\r\nsarial queries.
    To that end, we extend the meta-reduction technique\r\nof Bader et al. (EUROCRYPT’16)
    to also cover VRFs.\r\n2. This raises the question: Is this bound optimal? We
    answer this ques-\r\ntion in the affirmative by presenting the first VRF with
    a reduction\r\nfrom the non-interactive qDBDHI assumption to the security of VRF\r\nthat
    achieves this optimal loss.\r\nWe thus paint a complete picture of the achievability
    of tight verifiable\r\nrandom functions: We show that a security loss of Q is
    unavoidable and\r\npresent the first construction that achieves this bound."

  text: "In this article, we present an efficient descent method for locally Lipschitz\r\ncontinuous
    multiobjective optimization problems (MOPs). The method is realized\r\nby combining
    a theoretical result regarding the computation of descent\r\ndirections for nonsmooth
    MOPs with a practical method to approximate the\r\nsubdifferentials of the objective
    functions. We show convergence to points\r\nwhich satisfy a necessary condition
    for Pareto optimality. Using a set of test\r\nproblems, we compare our method
    to the multiobjective proximal bundle method by\r\nM\\\"akel\\\"a. The results
    indicate that our method is competitive while being\r\neasier to implement. While
    the number of objective function evaluations is\r\nlarger, the overall number
    of subgradient evaluations is lower. Finally, we\r\nshow that our method can be
    combined with a subdivision algorithm to compute\r\nentire Pareto sets of nonsmooth
    MOPs."

  text: It is a challenging task to identify the objectives on which a certain decision
    was based, in particular if several, potentially conflicting criteria are equally
    important and a continuous set of optimal compromise decisions exists. This task
    can be understood as the inverse problem of multiobjective optimization, where
    the goal is to find the objective function vector of a given Pareto set. To this
    end, we present a method to construct the objective function vector of an unconstrained
    multiobjective optimization problem (MOP) such that the Pareto critical set contains
    a given set of data points with prescribed KKT multipliers. If such an MOP can
    not be found, then the method instead produces an MOP whose Pareto critical set
    is at least close to the data points. The key idea is to consider the objective
    function vector in the multiobjective KKT conditions as variable and then search
    for the objectives that minimize the Euclidean norm of the resulting system of
    equations. By expressing the objectives in a finite-dimensional basis, we transform
    this problem into a homogeneous, linear system of equations that can be solved
    efficiently. Potential applications of this approach include the identification
    of objectives (both from clean and noisy data) and the construction of surrogate
    models for expensive MOPs.

  text: "Developing effective business models is a complex process for a company where
    several tasks (e.g., conduct customer interviews) need to be accomplished, and
    decisions (e.g., advertisement as a revenue stream) must be made. Here, domain
    experts can guide the choices of tasks and decisions with their knowledge. Nevertheless,
    this knowledge needs to match the situation of the company (e.g., financial resources)
    and the application domain of the product/service (e.g., mobile app) to reduce
    the risk of developing ineffective business models with low market penetration.
    This is not covered by one-size-fits-all development methods without tailoring
    before the enaction.\r\nTherefore, we conduct a design science study to create
    a situation-specific development approach for business models. Based on situational
    method engineering and our previous work in storing knowledge of methods and models
    in distinct repositories, this paper shows the situation-specific composition
    and enaction of business model development methods. First, the method engineer
    composes the development method out of both repositories based on the situational
    context. Second, the business developer enacts the method and develops the business
    model.  We implement the approach in a tool and evaluate it with a industrial
    case study on mobile apps."

  text: 'DC-DC converters for on-board chargers (OBC) of electrical vehicles are usually
    galvanically isolated allowing modular single-phase PFC front-end solutions, but
    require transformers which are more bulky, costly and lossy than inductors of
    non-isolated DC-DCs. Furthermore, for vehicle-to-grid applications, bidirectional
    converters with transformers are generally more complex and have a higher count
    on semiconductor switches than transformerless solutions. However, when using
    non-isolated DC-DC converters within an OBC, the large common-mode (CM) capacitance
    comprising capacitive parasitics of the traction battery as well as explicit Y-capacitors
    connecting the high-voltage DC-system (HV-system) within specific HV-loads to
    ground has to be considered. For the PFC front-end stage, when supplied from the
    three-phase mains this means that generation of high-frequency and high-amplitude
    CM voltages, as it is common e.g. with the conventional six-switch full-bridge
    converter, has to be strictly avoided. For this reason, a modified topology is
    suggested leading to a different mode of operation and to a very low common-mode
    noise behaviour: The three-phase four-wire full-bridge PFC with split DC-link,
    whose midpoint is connected to the mains neutral provides very stable potentials
    at the DC-link rails and therefore it can be classified as Zero-CM-topology.For
    dedicated single-phase operation, as required for most OBC, an additional balancing
    leg may be added to the topology to reduce the required DC-link capacitance and
    allow non-electrolytic capacitors.The function of the bidirectional Zero-CM three-phase
    four-wire full-bridge PFC was verified by simulation and on an 11 kW-laboratory
    sample. The power factor is above 0.999 and an efficiency of 98 % is measured.'

  text: 'In electric vehicles (EV) the large common-mode (CM) capacitance comprising
    capacitive parasitics of the traction battery as well as explicit Y-capacitors
    connecting within specific loads the high-voltage DC-system (HV-system) to ground,
    can cause issues when using non-isolated EV Chargers. One solution for a power
    factor correction (PFC) rectifier that is capable to operate with a non-isolated
    DC-DC converter, is the three-phase four-wire full-bridge PFC, with split DC-link,
    whose midpoint is connected to the mains neutral. Therefore, it provides very
    stable potentials at the DC-link rails and accordingly can be classified as Zero-CM
    topology, which facilitates a common-mode-free operation. When to be operated
    at a single-phase supply, which is a common requirement for On-board chargers
    (OBCs) this topology results in the voltage-doubler PFC (V2-PFC) being characterised
    by a comparably large DC-link voltage ripple at mains frequency. If the DC-link
    capacitance shall be minimized, for instance to avoid lifetime-limited electrolytic
    capacitors, two more circuits in addition to the original V2-PFC are proposed
    for keeping the common-mode-free operation: A balancing circuit (BC), that balances
    the voltages over the split capacitors and a ripple port (RP), that buffers the
    100 Hz power pulsation of the mains. For both circuits the available two bridge
    legs of the three-phase topology in single-phase operation may be utilized. A
    3.7 kW laboratory sample verifies the functionality of the additional circuits
    in conjunction with the V2-PFC and achieves an efficiency of 95 %.'
