  text: "We present a flexible trust region descend algorithm for unconstrained and\r\nconvexly
    constrained multiobjective optimization problems. It is targeted at\r\nheterogeneous
    and expensive problems, i.e., problems that have at least one\r\nobjective function
    that is computationally expensive. The method is\r\nderivative-free in the sense
    that neither need derivative information be\r\navailable for the expensive objectives
    nor are gradients approximated using\r\nrepeated function evaluations as is the
    case in finite-difference methods.\r\nInstead, a multiobjective trust region approach
    is used that works similarly to\r\nits well-known scalar pendants. Local surrogate
    models constructed from\r\nevaluation data of the true objective functions are
    employed to compute\r\npossible descent directions. In contrast to existing multiobjective
    trust\r\nregion algorithms, these surrogates are not polynomial but carefully\r\nconstructed
    radial basis function networks. This has the important advantage\r\nthat the number
    of data points scales linearly with the parameter space\r\ndimension. The local
    models qualify as fully linear and the corresponding\r\ngeneral scalar framework
    is adapted for problems with multiple objectives.\r\nConvergence to Pareto critical
    points is proven and numerical examples\r\nillustrate our findings."

  text: "Services often consist of multiple chained components such as microservices
    in a service mesh, or machine learning functions in a pipeline. Providing these
    services requires online coordination including scaling the service, placing instance
    of all components in the network, scheduling traffic to these instances, and routing
    traffic through the network. Optimized service coordination is still a hard problem
    due to many influencing factors such as rapidly arriving user demands and limited
    node and link capacity. Existing approaches to solve the problem are often built
    on rigid models and assumptions, tailored to specific scenarios. If the scenario
    changes and the assumptions no longer hold, they easily break and require manual
    adjustments by experts. Novel self-learning approaches using deep reinforcement
    learning (DRL) are promising but still have limitations as they only address simplified
    versions of the problem and are typically centralized and thus do not scale to
    practical large-scale networks.\r\n\r\nTo address these issues, we propose a distributed
    self-learning service coordination approach using DRL. After centralized training,
    we deploy a distributed DRL agent at each node in the network, making fast coordination
    decisions locally in parallel with the other nodes. Each agent only observes its
    direct neighbors and does not need global knowledge. Hence, our approach scales
    independently from the size of the network. In our extensive evaluation using
    real-world network topologies and traffic traces, we show that our proposed approach
    outperforms a state-of-the-art conventional heuristic as well as a centralized
    DRL approach (60% higher throughput on average) while requiring less time per
    online decision (1 ms)."

  text: Die kontinuierliche Weiterentwicklung des eigenen Geschäftsmodells ist für
    eine Organisation von entscheidender Bedeutung, um wettbewerbsfähig und somit
    nachhaltig erfolgreich zu bleiben. Während für die Entwicklung neuer Geschäftsmodelle
    häufig Workshops und einfache Software-Tools zur Visualisierung genutzt werden,
    wurden in der Forschung bereits erste Ansätze von datengetriebener Geschäftsmodellentwicklung
    (GME) vorgestellt. Diese Ansätze nutzen dabei Daten, Informationen oder auch Wissen
    aus internen und externen Unternehmensquellen, um den GME-Prozess zu unterstützen.
    Innerhalb dieses Beitrags zeigen wir einige Ansätze aus der aktuellen Literatur
    und analysieren wie ihre Datennutzung den GME-Prozess unterstützt. Weiterhin stellen
    wir mit dem BMDL Feature Modeler ein Tool vor, welches den GME-Prozess mit Expertenwissen
    unterstützt.

  text: <jats:p>Secret sharing is a well-established cryptographic primitive for storing
    highly sensitive information like encryption keys for encoded data. It describes
    the problem of splitting a secret into different shares, without revealing any
    information to its shareholders. Here, we demonstrate an all-optical solution
    for secret sharing based on metasurface holography. In our concept, metasurface
    holograms are used as spatially separable shares that carry encrypted messages
    in the form of holographic images. Two of these shares can be recombined by bringing
    them close together. Light passing through this stack of metasurfaces accumulates
    the phase shift of both holograms and optically reconstructs the secret with high
    fidelity. In addition, the hologram generated by each single metasurface can uniquely
    identify its shareholder. Furthermore, we demonstrate that the inherent translational
    alignment sensitivity between two stacked metasurface holograms can be used for
    spatial multiplexing, which can be further extended to realize optical rulers.</jats:p>

  text: 'The development of effective business models is an essential task in highly
    competitive markets like mobile ecosystems. Existing development methods for these
    business models do not specifically focus that the development process profoundly
    depends on the situation (e.g., market size, regulations) of the mobile app developer.
    Here, a mismatch between method and situation can lead to poor resource management
    and longer development cycles. In software engineering, situational method engineering
    is used for software projects to configure a development method out of a method
    repository based on the project situation. Analogously, we support creating situation-specific
    business model development methods with a method base and new user roles. Here,
    the method engineer obtains the knowledge of the domain expert and stores it in
    the method base as elements, building blocks, and patterns. The expert knowledge
    is derived from a grey literature review on mobile development processes. After
    this, the method engineer constructs the development method based on the described
    situation of the business developer. We provide an open-source tool and evaluate
    it by constructing a local event platform''s business model development method.    '

  text: <jats:p>Modern and flexible application-level software platforms increase
    the attack surface of connected vehicles and thereby require automotive engineers
    to adopt additional security control techniques. These techniques encompass host-based
    intrusion detection systems (HIDSs) that detect suspicious activities in application
    contexts. Such application-aware HIDSs originate in information and communications
    technology systems and have a great potential to deal with the flexible nature
    of application-level software platforms. However, the elementary characteristics
    of known application-aware HIDS approaches and thereby the implications for their
    transfer to the automotive sector are unclear. In previous work, we presented
    a systematic literature review (SLR) covering the state of the art of application-aware
    HIDS approaches. We synthesized our findings by means of a fine-grained classification
    for each approach specified through a feature model and corresponding variant
    models. These models represent the approaches’ elementary characteristics. Furthermore,
    we summarized key findings and inferred implications for the transfer of application-aware
    HIDSs to the automotive sector. In this article, we extend the previous work by
    several aspects. We adjust the quality evaluation process within the SLR to be
    able to consider high quality conference publications, which results in an extended
    final pool of publications. For supporting HIDS developers on the task of configuring
    HIDS analysis techniques based on machine learning, we report on initial results
    on the applicability of AutoML. Furthermore, we present lessons learned regarding
    the application of the feature and variant model approach for SLRs. Finally, we
    more thoroughly describe the SLR study design.</jats:p>

  text: "The laser sintering process has been a well-established AM process for many
    years.\r\nDisadvantages of LS are the low material variety and the thermal damage
    of the unprocessed\r\nmaterial. The low temperature laser sintering attacks at
    this point and processes powder material at\r\na build chamber temperature lower
    than the recrystallization temperature. This drastic reduction in\r\ntemperature
    results in significantly less thermal damage to the material. This work deals
    with the\r\nlow temperature laser sintering of Polyamide 12 (PA12) on a commercial,
    unmodified laser\r\nsintering system to compare it to standard laser sintered
    PA12 and to create the basis for low\r\ntemperature laser sintering of high temperature
    materials on such a system. First results by\r\nchanging the exposure parameters
    and by fixing parts on a building platform show a processing of\r\nPA12 on an
    EOS P396 at a build chamber temperature less than 100 °C instead of standard approx.\r\n175
    °C."

  text: GaAs-(111)-nanostructures exhibiting second harmonic generation are new building
    blocks in nonlinear optics. Such structures can be fabricated through epitaxial
    lift-off using selective etching of Al-containing layers and subsequent transfer
    to glass substrates. Herein, the selective etching of (111)B-oriented AlxGa1−xAs
    sacrificial layers (10–50 nm thick) with different aluminum concentrations (x
    = 0.5–1.0) in 10\% hydrofluoric acid is investigated and compared with standard
    (100)-oriented structures. The thinner the sacrificial layer and the lower the
    aluminum content, the lower the lateral etch rate. For both orientations, the
    lateral etch rates are in the same order of magnitude, but some quantitative differences
    exist. Furthermore, the epitaxial lift-off, the transfer, and the nanopatterning
    of thin (111)B-oriented GaAs membranes are demonstrated. Atomic force microscopy
    and high-resolution X-ray diffraction measurements reveal the high structural
    quality of the transferred GaAs-(111) films.

  text: "In practical, large-scale networks, services are requested\r\nby users across
    the globe, e.g., for video streaming.\r\nServices consist of multiple interconnected
    components such as\r\nmicroservices in a service mesh. Coordinating these services\r\nrequires
    scaling them according to continuously changing user\r\ndemand, deploying instances
    at the edge close to their users,\r\nand routing traffic efficiently between users
    and connected instances.\r\nNetwork and service coordination is commonly addressed\r\nthrough
    centralized approaches, where a single coordinator\r\nknows everything and coordinates
    the entire network globally.\r\nWhile such centralized approaches can reach global
    optima, they\r\ndo not scale to large, realistic networks. In contrast, distributed\r\napproaches
    scale well, but sacrifice solution quality due to their\r\nlimited scope of knowledge
    and coordination decisions.\r\n\r\nTo this end, we propose a hierarchical coordination
    approach\r\nthat combines the good solution quality of centralized approaches\r\nwith
    the scalability of distributed approaches. In doing so, we divide\r\nthe network
    into multiple hierarchical domains and optimize\r\ncoordination in a top-down
    manner. We compare our hierarchical\r\nwith a centralized approach in an extensive
    evaluation on a real-world\r\nnetwork topology. Our results indicate that hierarchical\r\ncoordination
    can find close-to-optimal solutions in a fraction of\r\nthe runtime of centralized
    approaches."

  text: Word embedding models reflect bias towards genders, ethnicities, and other
    social groups present in the underlying training data. Metrics such as ECT, RNSB,
    and WEAT quantify bias in these models based on predefined word lists representing
    social groups and bias-conveying concepts. How suitable these lists actually are
    to reveal bias - let alone the bias metrics in general - remains unclear, though.
    In this paper, we study how to assess the quality of bias metrics for word embedding
    models. In particular, we present a generic method, Bias Silhouette Analysis (BSA),
    that quantifies the accuracy and robustness of such a metric and of the word lists
    used. Given a biased and an unbiased reference embedding model, BSA applies the
    metric systematically for several subsets of the lists to the models. The variance
    and rate of convergence of the bias values of each model then entail the robustness
    of the word lists, whereas the distance between the models' values gives indications
    of the general accuracy of the metric with the word lists. We demonstrate the
    behavior of BSA on two standard embedding models for the three mentioned metrics
    with several word lists from existing research.

  text: We realize and investigate a nonlinear metasurface taking advantage of intersubband
    transitions in ultranarrow GaN/AlN multi-quantum well heterostructures. Owing
    to huge band offsets, the structures offer resonant transitions in the telecom
    window around 1.55 µm. These heterostructures are functionalized with an array
    of plasmonic antennas featuring cross-polarized resonances at these near-infrared
    wavelengths and their second harmonic. This kind of nonlinear metasurface allows
    for substantial second-harmonic generation at normal incidence which is completely
    absent for an antenna array without the multi-quantum well structure underneath.
    While the second harmonic is originally radiated only into the plane of the quantum
    wells, a proper geometrical arrangement of the plasmonic elements permits the
    redirection of the second-harmonic light to free-space radiation, which is emitted
    perpendicular to the surface.

  text: Self-training is an effective approach to semi-supervised learning. The key
    idea is to let the learner itself iteratively generate "pseudo-supervision" for
    unlabeled instances based on its current hypothesis. In combination with consistency
    regularization, pseudo-labeling has shown promising performance in various domains,
    for example in computer vision. To account for the hypothetical nature of the
    pseudo-labels, these are commonly provided in the form of probability distributions.
    Still, one may argue that even a probability distribution represents an excessive
    level of informedness, as it suggests that the learner precisely knows the ground-truth
    conditional probabilities. In our approach, we therefore allow the learner to
    label instances in the form of credal sets, that is, sets of (candidate) probability
    distributions. Thanks to this increased expressiveness, the learner is able to
    represent uncertainty and a lack of knowledge in a more flexible and more faithful
    manner. To learn from weakly labeled data of that kind, we leverage methods that
    have recently been proposed in the realm of so-called superset learning. In an
    exhaustive empirical evaluation, we compare our methodology to state-of-the-art
    self-supervision approaches, showing competitive to superior performance especially
    in low-label scenarios incorporating a high degree of uncertainty.
