  text: 'We review our results of numerical simulations of light scattering from different
    systems of densely packed irregular particles. We consider spherical clusters,
    thick layers and monolayers with realistic topologies and dimensions much larger
    than the wavelength of light. The maximum bulk packing density of clusters is
    0.5. A numerically exact solution of the electromagnetic problem is obtained using
    the Discontinuous Galerkin Time Domain method and with application of high- performance
    computing. We show that high packing density causes light localization in such
    structures which makes an impact on the opposition phenomena: backscattering intensity
    surge and negative linear polarization feature. Diffuse multiple scattering is
    significantly reduced in the case of non-absorbing particles and near-field interaction
    results in a percolation-like light transport determined by the topology of the
    medium. With this the negative polarization feature caused by single scattering
    gets enhanced if compared to lower density samples. We also confirm coherent double
    scattering mechanism of negative polarization for light scattered from dense absorbing
    slabs. In this case convergent result for the scattering angle polarization dependency
    at backscattering can be obtained for a layer of just a few tens of particles
    if they are larger than the wavelength.'

  text: "The intelligibility of demodulated audio signals from analog high frequency
    transmissions, e.g., using single-sideband\r\n(SSB) modulation, can be severely
    degraded by channel distortions and/or a mismatch between modulation and demodulation
    carrier frequency. In this work a neural network (NN)-based approach for carrier
    frequency offset (CFO) estimation from demodulated SSB signals is proposed, whereby
    a task specific architecture is presented. Additionally, a simulation framework
    for SSB signals is introduced and utilized for training the NNs. The CFO estimator
    is combined with a speech enhancement network to investigate its influence on
    the enhancement performance. The NN-based system is compared to a recently proposed
    pitch tracking based approach on publicly available data from real high frequency
    transmissions. Experiments show that the NN exhibits good CFO estimation properties
    and results in significant improvements in speech intelligibility, especially
    when combined with a noise reduction network."

  text: "The scope of speech enhancement has changed from a monolithic view of single,\r\nindependent
    tasks, to a joint processing of complex conversational speech\r\nrecordings. Training
    and evaluation of these single tasks requires synthetic\r\ndata with access to
    intermediate signals that is as close as possible to the\r\nevaluation scenario.
    As such data often is not available, many works instead\r\nuse specialized databases
    for the training of each system component, e.g\r\nWSJ0-mix for source separation.
    We present a Multi-purpose Multi-Speaker\r\nMixture Signal Generator (MMS-MSG)
    for generating a variety of speech mixture\r\nsignals based on any speech corpus,
    ranging from classical anechoic mixtures\r\n(e.g., WSJ0-mix) over reverberant
    mixtures (e.g., SMS-WSJ) to meeting-style\r\ndata. Its highly modular and flexible
    structure allows for the simulation of\r\ndiverse environments and dynamic mixing,
    while simultaneously enabling an easy\r\nextension and modification to generate
    new scenarios and mixture types. These\r\nmeetings can be used for prototyping,
    evaluation, or training purposes. We\r\nprovide example evaluation data and baseline
    results for meetings based on the\r\nWSJ corpus. Further, we demonstrate the usefulness
    for realistic scenarios by\r\nusing MMS-MSG to provide training data for the LibriCSS
    database."

    a measurement procedure to identify viscoelastic material parameters of plate-like

  text: "Recent advances in numerical methods significantly pushed forward the\r\nunderstanding
    of electrons coupled to quantized lattice vibrations. At this\r\nstage, it becomes
    increasingly important to also account for the effects of\r\nphysically inevitable
    environments. In particular, we study the transport\r\nproperties of the Hubbard-Holstein
    Hamiltonian that models a large class of\r\nmaterials characterized by strong
    electron-phonon coupling, in contact with a\r\ndissipative environment. Even in
    the one-dimensional and isolated case,\r\nsimulating the quantum dynamics of such
    a system with high accuracy is very\r\nchallenging due to the infinite dimensionality
    of the phononic Hilbert spaces.\r\nFor this reason, the effects of dissipation
    on the conductance properties of\r\nsuch systems have not been investigated systematically
    so far. We combine the\r\nnon-Markovian hierarchy of pure states method and the
    Markovian quantum jumps\r\nmethod with the newly introduced projected purified
    density-matrix\r\nrenormalization group, creating powerful tensor-network methods
    for dissipative\r\nquantum many-body systems. Investigating their numerical properties,
    we find a\r\nsignificant speedup up to a factor $\\sim 30$ compared to conventional\r\ntensor-network
    techniques. We apply these methods to study dissipative\r\nquenches, aiming for
    an in-depth understanding of the formation, stability, and\r\nquasi-particle properties
    of bipolarons. Surprisingly, our results show that in\r\nthe metallic phase dissipation
    localizes the bipolarons, which is reminiscent\r\nof an indirect quantum Zeno
    effect. However, the bipolaronic binding energy\r\nremains mainly unaffected,
    even in the presence of strong dissipation,\r\nexhibiting remarkable bipolaron
    stability. These findings shed light on the\r\nproblem of designing real materials
    exhibiting phonon-mediated\r\nhigh-$T_\\mathrm{C}$ superconductivity."

  text: "We develop a general decomposition of an ensemble of initial density profiles\r\nin
    terms of an average state and a basis of modes that represent the\r\nevent-by-event
    fluctuations of the initial state. The basis is determined such\r\nthat the probability
    distributions of the amplitudes of different modes are\r\nuncorrelated. Based
    on this decomposition, we quantify the different types and\r\nprobabilities of
    event-by-event fluctuations in Glauber and Saturation models\r\nand investigate
    how the various modes affect different characteristics of the\r\ninitial state.
    We perform simulations of the dynamical evolution with KoMPoST\r\nand MUSIC to
    investigate the impact of the modes on final-state observables and\r\ntheir correlations."

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>RNA editing processes
    are strikingly different in animals and plants. Up to thousands of specific cytidines
    are converted into uridines in plant chloroplasts and mitochondria whereas up
    to millions of adenosines are converted into inosines in animal nucleo-cytosolic
    RNAs. It is unknown whether these two different RNA editing machineries are mutually
    incompatible. RNA-binding pentatricopeptide repeat (PPR) proteins are the key
    factors of plant organelle cytidine-to-uridine RNA editing. The complete absence
    of PPR mediated editing of cytosolic RNAs might be due to a yet unknown barrier
    that prevents its activity in the cytosol. Here, we transferred two plant mitochondrial
    PPR-type editing factors into human cell lines to explore whether they could operate
    in the nucleo-cytosolic environment. PPR56 and PPR65 not only faithfully edited
    their native, co-transcribed targets but also different sets of off-targets in
    the human background transcriptome. More than 900 of such off-targets with editing
    efficiencies up to 91%, largely explained by known PPR-RNA binding properties,
    were identified for PPR56. Engineering two crucial amino acid positions in its
    PPR array led to predictable shifts in target recognition. We conclude that plant
    PPR editing factors can operate in the entirely different genetic environment
    of the human nucleo-cytosol and can be intentionally re-engineered towards new
    targets.</jats:p>"

  text: "We study the influence of fringing magnetic fields on turbulent thermal\r\nconvection
    in a horizontally extended rectangular domain. The magnetic field is\r\ncreated
    in the gap between two semi-infinite planar magnetic poles, with the\r\nconvection
    layer located near the edge of the gap. We employ direct numerical\r\nsimulations
    in this setup for fixed Rayleigh and small Prandtl numbers, but\r\nvary the fringe-width
    by controlling the gap between the magnetic poles and the\r\nconvection cell.
    The magnetic field generated by the magnets is strong enough\r\nto cease the flow
    in high magnetic flux region of the convection cell. We\r\nobserve that as the
    local vertical magnetic field strength increases, the large\r\nscale structures
    become thinner and align themselves perpendicular to the\r\nlongitudinal sidewalls.
    We determine the local Nusselt and Reynolds numbers as\r\nfunctions of the local
    Hartmann number (based on the vertical component of the\r\nmagnetic field) and
    estimate the global heat and momentum transport. We show\r\nthat the global heat
    transport decreases with increasing fringe-width for\r\nstrong magnetic fields
    but increases with increasing fringe-width for weak\r\nmagnetic fields. In the
    regions of large vertical magnetic fields, the\r\nconvective motion becomes confined
    to the vicinity of the sidewalls. The\r\namplitudes of these wall modes show a
    non-monotonic dependence on the\r\nfringe-width."

  text: Optical traveling wave antennas offer unique opportunities to control and
    selectively guide light into a specific direction, which renders them excellent
    candidates for optical communication and sensing. These applications require state-of-the-art
    engineering to reach optimized functionalities such as high directivity and radiation
    efficiency, low sidelobe levels, broadband and tunable capabilities, and compact
    design. In this work, we report on the numerical optimization of the directivity
    of optical traveling wave antennas made from low-loss dielectric materials using
    full-wave numerical simulations in conjunction with the particle swarm optimization
    algorithm. The antennas are composed of a reflector and a director deposited on
    a glass substrate, and an emitter placed in the feed gap between them serves as
    an internal source of excitation. In particular, we analyze antennas with rectangular-
    and horn-shaped directors made of either hafnium dioxide or silicon. The optimized
    antennas produce highly directional emissions due to the presence of two dominant
    guided TE modes in the director in addition to leaky modes. These guided modes
    dominate the far-field emission pattern and govern the direction of the main lobe
    emission, which predominately originates from the end facet of the director. Our
    work also provides a comprehensive analysis of the modes, radiation patterns,
    parametric influences, and bandwidths of the antennas, which highlights their
    robust nature.

  text: We study a double-scattering coherent mechanism of negative polarization (NP)
    near opposition that is observed for powder-like surfaces. The problem is solved
    numerically for absorbing structures with irregular constituents, cubes, spheres,
    and ellipsoids larger than the wavelength of incident light. Our simulations show
    that double scattering between two random irregular particles shows weak NP. Adding
    one more particle significantly increases the relative contribution of double
    scattering which enhances NP. Simulations with regular shapes and controlled geometric
    parameters show that the interference mechanism is sensitive to the geometry of
    the scattering system and can also result in no polarization or even strong enhancement
    of positive polarization at backscattering.

  text: Highly directive antennas with the ability of shaping radiation patterns in
    desired directions are essential for efficient on-chip optical communication with
    reduced cross talk. In this paper, we design and optimize three distinct broadband
    traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics.
    Our antennas contain a director and reflector deposited on a glass substrate,
    which are excited by a dipole emitter placed in the feed gap between the two elements.
    Full-wave simulations in conjunction with global optimization provide structures
    with an enhanced linear directivity as high as 119 radiating in the substrate.
    The high directivity is a result of the interplay between two dominant TE modes
    and the leaky modes present in the antenna director. Furthermore, these low-loss
    dielectric antennas exhibit a near-unity radiation efficiency at the operational
    wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are
    in good agreement with experimental measurements from the optimized antennas fabricated
    using a two-step electron-beam lithography, revealing the highly directive nature
    of our structures. We envision that our antenna designs can be conveniently adapted
    to other dielectric materials and prove instrumental for inter-chip optical communications
    and other on-chip applications.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The interaction
    between quantum light and matter is being intensively studied for systems that
    are enclosed in high-<jats:italic>Q</jats:italic> cavities which strongly enhance
    the light–matter coupling. Cavities with low <jats:italic>Q</jats:italic>-factors
    are generally given less attention due to their high losses that quickly destroy
    quantum systems. However, bad cavities can be utilized for several applications,
    where lower <jats:italic>Q</jats:italic>-factors are required, e.g., to increase
    the spectral width of the cavity mode. In this work, we demonstrate that low-<jats:italic>Q</jats:italic>
    cavities can be beneficial for preparing specific electronic steady states when
    certain quantum states of light are applied. We investigate the interaction between
    quantum light with various statistics and matter represented by a Λ-type three-level
    system in lossy cavities, assuming that cavity losses are the dominant loss mechanism.
    We show that cavity losses lead to non-trivial electronic steady states that can
    be controlled by the loss rate and the initial statistics of the quantum fields.
    We discuss the mechanism of the formation of such steady states on the basis of
    the equations of motion and present both analytical expressions and numerical
    simulations for such steady states.</jats:p>"
