  text: A key challenge in designing efficient optical phased arrays is the lack of
    a well-designed radiator. This work explores horn antennas numerically optimized
    to target high upward radiation efficiency to be employed in silicon-based phased
    arrays capable of producing elegant radiation patterns in the far-field.

    The article shows how to learn models of dynamical systems
    from data which are governed by an unknown variational PDE. Rather
    than employing reduction techniques, we learn a discrete field theory
    governed by a discrete Lagrangian density Ld that is modelled as a neural network. Careful regularisation of the loss function for training Ld is
    necessary to obtain a field theory that is suitable for numerical computations: we derive a regularisation term which optimises the solvability of
    the discrete Euler–Lagrange equations. Secondly, we develop a method to
    find solutions to machine learned discrete field theories which constitute
    travelling waves of the underlying continuous PDE.

  text: Dielectric metasurfaces provide a unique platform for efficient harmonic generation
    and optical wavefront manipulation at the nanoscale. Tailoring phase and amplitude
    of a nonlinearly generated wave with a high emission efficiency using resonance-based
    metasurfaces is a challenging task that often requires state-of-the-art numerical
    methods. Here, we propose a simple yet effective approach combining a sampling
    method with a Monte Carlo approach to design the third-harmonic wavefront generated
    by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using
    this approach, we theoretically demonstrate the full nonlinear 2π phase control
    with a uniform and highest possible amplitude in the considered parameter space,
    allowing us to design metasurfaces operating as third harmonic beam deflectors
    capable of steering light into a desired direction with high emission efficiency.
    The TH beam deflection with a record calculated average conversion efficiency
    of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be
    widely applied as alternative to commonly used optimization algorithms with higher
    complexity and implementation effort for the design of metasurfaces with other
    holographic functionalities.

  text: A series of new organic donor–π–acceptor dyes incorporating a diquat moiety
    as a novel electron-acceptor unit have been synthesized and characterized. The
    analytical data were supported by DFT calculations. These dyes were explored in
    the aerobic thiocyanation of indoles and pyrroles. Here they showed a high photocatalytic
    activity under visible light, giving isolated yields of up to 97 %. In addition,
    the photocatalytic activity of standalone diquat and methyl viologen through formation
    of an electron donor acceptor complex is presented.

  text: "<jats:p>While FPGA accelerator boards and their respective high-level design
    tools are maturing, there is still a lack of multi-FPGA applications, libraries,
    and not least, benchmarks and reference implementations towards sustained HPC
    usage of these devices. As in the early days of GPUs in HPC, for workloads that
    can reasonably be decoupled into loosely coupled working sets, multi-accelerator
    support can be achieved by using standard communication interfaces like MPI on
    the host side. However, for performance and productivity, some applications can
    profit from a tighter coupling of the accelerators. FPGAs offer unique opportunities
    here when extending the dataflow characteristics to their communication interfaces.</jats:p>\r\n
    \         <jats:p>In this work, we extend the HPCC FPGA benchmark suite by multi-FPGA
    support and three missing benchmarks that particularly characterize or stress
    inter-device communication: b_eff, PTRANS, and LINPACK. With all benchmarks implemented
    for current boards with Intel and Xilinx FPGAs, we established a baseline for
    multi-FPGA performance. Additionally, for the communication-centric benchmarks,
    we explored the potential of direct FPGA-to-FPGA communication with a circuit-switched
    inter-FPGA network that is currently only available for one of the boards. The
    evaluation with parallel execution on up to 26 FPGA boards makes use of one of
    the largest academic FPGA installations.</jats:p>"

  text: "The computation of electron repulsion integrals (ERIs) over Gaussian-type
    orbitals (GTOs) is a challenging problem in quantum-mechanics-based atomistic
    simulations. In practical simulations, several trillions of ERIs may have to be\r\ncomputed
    for every time step.\r\nIn this work, we investigate FPGAs as accelerators for
    the ERI computation. We use template parameters, here within the Intel oneAPI
    tool flow, to create customized designs for 256 different ERI quartet classes,
    based on their orbitals. To maximize data reuse, all intermediates are buffered
    in FPGA on-chip memory with customized layout. The pre-calculation of intermediates
    also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations.
    The involved loop structures are partially or even fully unrolled for high throughput
    of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary
    bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge,
    this is the first work on ERI computation on FPGAs that supports more than just
    the single most basic quartet class. Also, the integration of ERI computation
    and compression it a novelty that is not even covered by CPU or GPU libraries
    so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression,
    the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$
    ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors
    around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately
    explained by a performance model. The FPGA kernels deployed on 2 FPGAs outperform
    similar computations using the widely used libint reference on a two-socket server
    with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up
    to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x."

  text: Due to the high variation in the application requirements of sound event detection
    (SED) systems, it is not sufficient to evaluate systems only in a single operating
    mode. Therefore, the community recently adopted the polyphonic sound detection
    score (PSDS) as an evaluation metric, which is the normalized area under the PSD
    receiver operating characteristic (PSD-ROC). It summarizes the system performance
    over a range of operating modes resulting from varying the decision threshold
    that is used to translate the system output scores into a binary detection output.
    Hence, it provides a more complete picture of the overall system behavior and
    is less biased by specific threshold tuning. However, besides the decision threshold
    there is also the post-processing that can be changed to enter another operating
    mode. In this paper we propose the post-processing independent PSDS (piPSDS) as
    a generalization of the PSDS. Here, the post-processing independent PSD-ROC includes
    operating points from varying post-processings with varying decision thresholds.
    Thus, it summarizes even more operating modes of an SED system and allows for
    system comparison without the need of implementing a post-processing and without
    a bias due to different post-processings. While piPSDS can in principle combine
    different types of post-processing, we here, as a first step, present median filter
    independent PSDS (miPSDS) results for this year’s DCASE Challenge Task4a systems.

  text: "\tWe propose a general framework to compute the word error rate (WER) of
    ASR systems that process recordings containing multiple speakers at their input
    and that produce multiple output word sequences (MIMO).\r\n\tSuch ASR systems
    are typically required, e.g., for meeting transcription.\r\n\tWe provide an efficient
    implementation based on a dynamic programming search in a multi-dimensional Levenshtein
    distance tensor under the constraint that a reference utterance must be matched
    consistently with one hypothesis output. \r\n\tThis also results in an efficient
    implementation of the ORC WER which previously suffered from exponential complexity.\r\n\tWe
    give an overview of commonly used WER definitions for multi-speaker scenarios
    and show that they are specializations of the above MIMO WER tuned to particular
    application scenarios. \r\n\tWe conclude with a  discussion of the pros and cons
    of the various WER definitions and a recommendation when to use which."

  text: "MeetEval is an open-source toolkit to evaluate  all kinds of meeting transcription
    systems.\r\nIt provides a unified interface for the computation of commonly used
    Word Error Rates (WERs), specifically cpWER, ORC WER and MIMO WER along other
    WER definitions.\r\nWe extend the cpWER computation by a temporal constraint to
    ensure that only words are identified as correct when the temporal alignment is
    plausible.\r\nThis leads to a better quality of the matching of the hypothesis
    string to the reference string that more closely resembles the actual transcription
    quality, and a system is penalized if it provides poor time annotations.\r\nSince
    word-level timing information is often not available, we present a way to approximate
    exact word-level timings from segment-level timings (e.g., a sentence) and show
    that the approximation leads to a similar WER as a matching with exact word-level
    annotations.\r\nAt the same time, the time constraint leads to a speedup of the
    matching algorithm, which outweighs the additional overhead caused by processing
    the time stamps."
