text: Polarization of light is essential for some living organisms and many optical
applications. Here, an orientation dependent polarization conversion effect is
reported for light reflected from diamond‐structure‐based photonic crystals (D‐structure)
inside the scales of a beetle, the weevil Entimus imperialis. When linearly polarized
light propagates along its 〈100〉 directions, the D‐structure behaves analogous
to a half‐wave plate in reflection but based on a different mechanism. The D‐structure
rotates the polarization direction of linearly polarized light, and reflects circularly
polarized light of both handednesses without changing it. This polarization effect
is different from circular dichroism occurring in chiral biological photonic structures
discovered before. The structural origin of this effect is symmetry breaking inside
D‐structure's unit cell. This finding demonstrates that natural photonic structures
can exploit multiple functionalities inherent to the design principles of their
structural organization. Aiming at transferring the inherent polarization effect
of the biological D‐structure to technically realizable materials, three simplified
biomimetic structural models are derived and it is theoretically demonstrated
that they retain the effect. Out of these structures, functioning woodpile structure
prototypes are fabricated.

text: Metal nanoparticles host localized plasmon excitations that allow the manipulation
of optical fields at the nanoscale. Despite the availability of several techniques
for imaging plasmons, direct access into the symmetries of these excitations remains
elusive, thus hindering progress in the development of applications. Here, we
present a combination of angle-, polarization-, and space-resolved cathodoluminescence
spectroscopy methods to selectively access the symmetry and degeneracy of plasmonic
states in lithographically fabricated gold nanoprisms. We experimentally reveal
and spatially map degenerate states of multipole plasmon modes with nanometer
spatial resolution and further provide recipes for resolving optically dark and
out-of-plane modes. Full-wave simulations in conjunction with a simple tight-binding
model explain the complex plasmon structure in these particles and reveal intriguing
mode-symmetry phenomena. Our approach introduces systematics for a comprehensive
symmetry characterization of plasmonic states in high-symmetry nanostructures.

text: "We study the dependence of the intensity and linear polarization of light
scattered by isolated particles with the compact\r\nirregular shape on their size
using the discontinuous Galerkin time domain numerical method. The size parameter
of particles varies in the range of X = 10 to 150, and the complex refractive
index is m = 1.5 + 0i. Our results show\r\nthat the backscattering negative polarization
branch weakens monotonously, but does not disappear at large sizes, up to the
geometrical optics regime, and can be simulated without accounting for wave effects.
The intensity backscattering surge becomes narrower with increasing particle size.
For X = 150, the surge width is several degrees."

text: In diesem Beitrag werden simulatorische und messtechnische EMV-Untersuchungen
von Gleichspannungswandlern vorgestellt. Der Fokus liegt auf leitungsgeführten
Störspannungen, ihre Abhängigkeit vom Schaltungslayout und ihre Unterdrückung
durch Filterung. Der Simulationsprozess besteht aus kombinierten Feld- und Netzwerksimulationen.
Zur Bewertung der Simulationsresultate werden zwei Prototypen gezeigt, die gute
und schlechte EMV-Eigenschaften aufweisen. Bei der Beurteilung der Resultate wird
insbesondere Wert auf die Untersuchung gelegt, inwieweit einfache Schaltungssimulationen
ausreichen, um leitungsgeführte Störspannungen korrekt vorherzusagen und wann
aufwändigere Feldsimulationen notwendig sind.

text: Acoustic event detection, i.e., the task of assigning a human interpretable
label to a segment of audio, has only recently attracted increased interest in
the research community. Driven by the DCASE challenges and the availability of
large-scale audio datasets, the state-of-the-art has progressed rapidly with deep-learning-based
classi- fiers dominating the field. Because several potential use cases favor
a realization on distributed sensor nodes, e.g. ambient assisted living applications,
habitat monitoring or surveillance, we are concerned with two issues here. Firstly
the classification performance of such systems and secondly the computing resources
required to achieve a certain performance considering node level feature extraction.
In this contribution we look at the balance between the two criteria by employing
traditional techniques and different deep learning architectures, including convolutional
and recurrent models in the context of real life everyday audio recordings in
realistic, however challenging, multisource conditions.

text: Signal dereverberation using the weighted prediction error (WPE) method has
been proven to be an effective means to raise the accuracy of far-field speech
recognition. But in its original formulation, WPE requires multiple iterations
over a sufficiently long utterance, rendering it unsuitable for online low-latency
applications. Recently, two methods have been proposed to overcome this limitation.
One utilizes a neural network to estimate the power spectral density (PSD) of
the target signal and works in a block-online fashion. The other method relies
on a rather simple PSD estimation which smoothes the observed PSD and utilizes
a recursive formulation which enables it to work on a frame-by-frame basis. In
this paper, we integrate a deep neural network (DNN) based estimator into the
recursive frame-online formulation. We evaluate the performance of the recursive
system with different PSD estimators in comparison to the block-online and offline
variant on two distinct corpora. The REVERB challenge data, where the signal is
mainly deteriorated by reverberation, and a database which combines WSJ and VoiceHome
to also consider (directed) noise sources. The results show that although smoothing
works surprisingly well, the more sophisticated DNN based estimator shows promising
improvements and shortens the performance gap between online and offline processing.

text: We present a block-online multi-channel front end for automatic speech recognition
in noisy and reverberated environments. It is an online version of our earlier
proposed neural network supported acoustic beamformer, whose coefficients are
calculated from noise and speech spatial covariance matrices which are estimated
utilizing a neural mask estimator. However, the sparsity of speech in the STFT
domain causes problems for the initial beamformer coefficients estimation in some
frequency bins due to lack of speech observations. We propose two methods to mitigate
this issue. The first is to lower the frequency resolution of the STFT, which
comes with the additional advantage of a reduced time window, thus lowering the
latency introduced by block processing. The second approach is to smooth beamforming
coefficients along the frequency axis, thus exploiting their high interfrequency
correlation. With both approaches the gap between offline and block-online beamformer
performance, as measured by the word error rate achieved by a downstream speech
recognizer, is significantly reduced. Experiments are carried out on two copora,
representing noisy (CHiME-4) and noisy reverberant (voiceHome) environments.

text: 'The weighted prediction error (WPE) algorithm has proven to be a very successful
dereverberation method for the REVERB challenge. Likewise, neural network based
mask estimation for beamforming demonstrated very good noise suppression in the
CHiME 3 and CHiME 4 challenges. Recently, it has been shown that this estimator
can also be trained to perform dereverberation and denoising jointly. However,
up to now a comparison of a neural beamformer and WPE is still missing, so is
an investigation into a combination of the two. Therefore, we here provide an
extensive evaluation of both and consequently propose variants to integrate deep
neural network based beamforming with WPE. For these integrated variants we identify
a consistent word error rate (WER) reduction on two distinct databases. In particular,
our study shows that deep learning based beamforming benefits from a model-based
dereverberation technique (i.e. WPE) and vice versa. Our key findings are: (a)
Neural beamforming yields the lower WERs in comparison to WPE the more channels
and noise are present. (b) Integration of WPE and a neural beamformer consistently
outperforms all stand-alone systems.'
