  text: "Modern services often comprise several components, such as chained virtual
    network functions, microservices, or\r\nmachine learning functions. Providing
    such services requires to decide how often to instantiate each component, where
    to place these instances in the network, how to chain them and route traffic through
    them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep
    reinforcement learning (DRL) approaches for self-learning network and service
    management have emerged recently. These model-free DRL approaches are more flexible
    but typically learn tabula rasa, i.e., disregard existing understanding of networks,
    services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel
    model-based AI approach that leverages existing understanding of networks and
    services for more efficient and effective coordination without time-intensive
    training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic
    model. This allows FutureCoord to estimate the impact of future incoming traffic
    and effectively optimize long-term effects, taking fluctuating demand and Quality
    of Service (QoS) requirements into account. Our extensive evaluation based on
    real-world network topologies, services, and traffic traces indicates that FutureCoord
    clearly outperforms state-of-the-art model-free and model-based approaches with
    up to 51% higher flow success ratios."

  text: "Modern-day communication has become more and more digital. While this comes
    with many advantages such as a more efficient economy, it has also created more
    and more opportunities for various adversaries to manipulate communication or
    eavesdrop on it. The Snowden revelations in 2013 further highlighted the seriousness
    of these threats. To protect the communication of people, companies, and states
    from such threats, we require cryptography with strong security guarantees.\r\nDifferent
    applications may require different security properties from cryptographic schemes.
    For most applications, however, so-called adaptive security is considered a reasonable
    minimal requirement of security. Cryptographic schemes with adaptive security
    remain secure in the presence of an adversary that can corrupt communication partners
    to respond to messages of the adversaries choice, while the adversary may choose
    the messages based on previously observed interactions.\r\nWhile cryptography
    is associated the most with encryption, this is only one of many primitives that
    are essential for the security of digital interactions. This thesis presents novel
    identity-based encryption (IBE) schemes and verifiable random functions (VRFs)
    that achieve adaptive security as outlined above. Moreover, the cryptographic
    schemes presented in this thesis are proven secure in the standard model. That
    is without making use of idealized models like the random oracle model."

  text: Optical geometric phase encoded by in-plane spatial orientation of microstructures
    has promoted the rapid development of numerous functional meta-devices. However,
    pushing the concept of the geometric phase toward the acoustic community still
    faces challenges. In this work, we utilize two acoustic nonlocal metagratings
    that could support a direct conversion between an acoustic plane wave and a designated
    vortex mode to obtain the acoustic geometric phase, in which an orbital angular
    momentum conversion process plays a vital role. In addition, we realize the acoustic
    geometric phases of different orders by merely varying the orientation angle of
    the acoustic nonlocal metagratings. Intriguingly, according to our developed theory,
    we reveal that the reflective acoustic geometric phase, which is twice the transmissive
    one, can be readily realized by transferring the transmitted configuration to
    a reflected one. Both the theoretical study and experimental measurements verify
    the announced transmissive and reflective acoustic geometric phases. Moreover,
    the reconfigurability and continuous phase modulation that covers the 2π range
    shown by the acoustic geometric phases provide us with the alternatives in advanced
    acoustic wavefront control.

  text: We investigate bifurcations in feedforward coupled cell networks. Feedforward
    structure (the absence of feedback) can be defined by a partial order on the cells.
    We use this property to study generic one-parameter steady state bifurcations
    for such networks. Branching solutions and their asymptotics are described in
    terms of Taylor coefficients of the internal dynamics. They can be determined
    via an algorithm that only exploits the network structure. Similar to previous
    results on feedforward chains, we observe amplifications of the growth rates of
    steady state branches induced by the feedforward structure. However, contrary
    to these earlier results, as the interaction scenarios can be more complicated
    in general feedforward networks, different branching patterns and different amplifications
    can occur for different regions in the space of Taylor coefficients.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The round robin
    test investigated the reliability users can expect for AlSi10Mg additive manufactured
    specimens by laser powder bed fusion through examining powder quality, process
    parameter, microstructure defects, strength and fatigue. Besides for one outlier,
    expected static material properties could be found. Optical microstructure inspection
    was beneficial to determine true porosity and porosity types to explain the occurring
    scatter in properties. Fractographic analyses reveal that the fatigue crack propagation
    starts at the rough as-built surface for all specimens. Statistical analysis of
    the scatter in fatigue using statistical derived safety factors concludes that
    at a stress of 36.87 MPa the fatigue limit of 10<jats:sup>7</jats:sup> cycles
    could be reached for all specimen with a survival probability of 99.999 %.</jats:p>"

  text: '<jats:p> A process sequence enabling the large-area fabrication of nanopillar-patterned
    semiconductor templates for selective-area heteroepitaxy is developed. Herein,
    the nanopillar tops surrounded by a SiN<jats:sub>x</jats:sub> mask film serve
    as nanoscale growth areas. The molecular beam epitaxial growth of InAs on such
    patterned GaAs[Formula: see text]A templates is investigated by means of electron
    microscopy. It is found that defect-free nanoscale InAs islands grow selectively
    on the nanopillar tops at a substrate temperature of 425 °C. High-angle annular
    dark-field scanning transmission electron microscopy imaging reveals that for
    a growth temperature of 400 °C, the InAs islands show a tendency to form wurtzite
    phase arms extending along the lateral [Formula: see text] directions from the
    central zinc blende region of the islands. This is ascribed to a temporary self-catalyzed
    vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically
    induced preference for the nucleation of the wurtzite phase driven by the local,
    instantaneous V/III ratio, and to a concomitant reduction of surface energy of
    the nanoscale diameter arms. </jats:p>'

  text: Transformation of Fe- and Cu-rich primary phase particles was studied in an
    Al-Li-based alloy prepared by twin-roll casting. Thin foils for combined STEM
    and SEM experiments were prepared by electrolytic twin-jet polishing. They were
    in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS
    electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and
    SE detectors working both in composition and topographic modes. The resulting
    structures were combined with EDS mapping performed directly in the heating holder.
    Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C.
    EDS maps acquired on the foil cooled down to room temperature show that Cu and
    Fe are both still present in newly formed particles, most likely indicating the
    presence of the Al7Cu2Fe phase.

  text: <jats:p> Recently, microcavities with anisotropic materials were shown to
    be able to create bands with non-zero local Berry curvature. The anisotropic refractive
    index of the cavity layer is believed to be critical in opening an energy gap
    at the tilted Dirac points. In this work, we show that the anticrossing between
    a cavity mode and a Bragg mode can also be realized within an empty microcavity
    without any birefringent materials in the cavity layer. Nondispersive bands are
    observed within the energy gap due to the particular refractive index distribution
    of the sample. The intrinsic TE-TM splitting and XY splitting of DBR mirrors induce
    the squeezing of the cavity modes in momentum space, so that the nondispersive
    bands are tilted and spin-dependent. Our results pave the way to investigate interesting
    physical phenomena of photonic modes close to or in the nondispersive bands without
    anisotropic cavity layers. </jats:p>

    is a promising platform for integrated quantum optics. In this platform, we aim
    to efficiently manipulate and detect quantum states by combining superconducting
    single photon detectors and modulators. The cryogenic operation of a superconducting
    single photon detector dictates the optimisation of the electro-optic modulators
    under the same operating conditions. To that end, we characterise a phase modulator,
    directional coupler, and polarisation converter at both ambient and cryogenic

  text: <jats:p> Superconducting Nanowire Single Photon Detectors (SNSPDs) have become
    an integral part of quantum optics in recent years because of their high performance
    in single photon detection. We present a method to replace the electrical input
    by supplying the required bias current via the photocurrent of a photodiode situated
    on the cold stage of the cryostat. Light is guided to the bias photodiode through
    an optical fiber, which enables a lower thermal conduction and galvanic isolation
    between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP
    photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device
    to bias an SNSPD, we characterize the count rate dependent on the optical power
    incident on the photodiode. This configuration of the SNSPD and photodiode shows
    an expected plateau in the single photon count rate with an optical bias power
    on the photodiode above 6.8 µW. Furthermore, we compare the same detector under
    both optical and electrical bias, and show there is no significant changes in
    performance. This has the advantage of avoiding an electrical input cable, which
    reduces the latent heat load by a factor of 100 and, in principle, allows for
    low loss RF current supply at the cold stage. </jats:p>

  text: Recent analyses by polarization resolved second-harmonic (SH) microscopy have
    demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising
    wall characteristics and topological nature. These analyses rely on locally analyzing
    the properties, directionality, and magnitude of the second-order nonlinear tensor.
    However, when inspecting FE DWs with SH microscopy, a manifold of different effects
    may contribute to the observed signal difference between domains and DWs, i.e.,
    far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the
    aforementioned local nonlinear optical properties. They all might be present at
    the same time and, therefore, require careful interpretation and separation. In
    this work, we demonstrate how the particularly strong Čerenkov-type contrast can
    selectively be blocked using dark- and bright-field SH microscopy. Based on this
    approach, we show that other contrast mechanisms emerge that were previously overlayed
    by CSHG but can now be readily selected through the appropriate experimental geometry.
    Using the methods presented, we show that the strength of the CSHG contrast compared
    to the other mechanisms is approximately 22 times higher. This work lays the foundation
    for the in-depth analysis of FE DW topologies by SH microscopy.
