text: In this paper, machine learning techniques will be used to classify different
PCB layouts given their electromagnetic frequency spectra. These spectra result
from a simulated near-field measurement of electric field strengths at different
locations. Measured values consist of real and imaginary parts (amplitude and
phase) in X, Y and Z directions. Training data was obtained in the time domain
by varying transmission line geometries (size, distance and signaling). It was
then transformed into the frequency domain and used as deep neural network input.
Principal component analysis was applied to reduce the sample dimension. The results
show that classifying different designs is possible with high accuracy based on
synthetic data. Future work comprises measurements of real, custom-made PCB with
varying parameters to adapt the simulation model and also test the neural network.
Finally, the trained model could be used to give hints about the error’s cause
when overshooting EMC limits.

text: We model negative polarization, which is observed for planetary regoliths
at backscattering, solving a full wave problem of light scattering with a numerically
exact Discontinuous Galerkin Time Domain (DGTD) method. Pieces of layers with
the bulk packing density of particles close to 0.5 are used. The model particles
are highly absorbing and have irregular shapes and sizes larger than the wavelength
of light. This represents a realistic analog of low-albedo planetary regoliths.
Our simulations confirm coherent backscattering mechanism of the origin of negative
polarization. We show that angular profiles of polarization are stabilized if
the number of particles in a layer piece becomes larger than ten. This allows
application of our approach to the negative polarization modeling for planetary
regoliths.

text: In this work, methods will be evaluated to numerically calculate the passive
electrical parameters of planar coils. These parameters can then be used to optimize
inductive applications such as wireless power transmission. The focus here will
be on inductive localization, which uses high-frequency magnetic fields and the
resulting induced voltage to provide localization through the coupling parameter
mutual inductance. To achieve localization with high accuracy and best possible
operation (resonance, signal strength, etc.), the coil parameters need to be well
known. For this reason, some numerical methods for the calculation of these quantities
are presented and validated. In addition, the physical effects are thereby considered
in more detail, allowing the localization procedure to be better optimized compared
to simulative black-box methods. The goal should be a dedicated simulation platform
for planar coils to be able to develop training data for neural networks and to
test and optimize localization algorithms.

text: In the manufacture of real wood products, defects can quickly occur during
the production process. To quickly sort out these defects, a system is needed
that finds damage in the irregularly structured surfaces of the product. The difficulty
in this task is that each surface is visually different and no standard defects
can be defined. Thus, damage detection using correlation does not work, so this
paper will test different machine learning methods. To evaluate different machine
learning methods, a data set is needed. For this reason, the available samples
were recorded manually using a static fixed camera. Subsequently, the images were
divided into sub-images, which resulted in a relatively small data set. Next,
a convolutional neural network (CNN) was constructed to classify the images. However,
this approach did not lead to a generalized solution, so the dataset was hashed
using the a- and pHash. These hash values were then trained with a fully supervised
system that will later serve as a reference model, in the semi-supervised learning
procedures. To improve the supervised model and not have to label every data point,
semi-supervised learning methods are used in the following. For this purpose,
the CEAL method (wrapper method) is considered in the first and then the Π-Model
(intrinsically semi-supervised).

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."

text: "Abstract\r\n In this paper
a measurement procedure to identify viscoelastic material parameters of plate-like
samples using broadband ultrasonic waves is presented. Ultrasonic Lamb waves are
excited via the thermoelastic effect using laser radiation and detected by a piezoelectric
transducer. The resulting measurement data is transformed to yield information
about multiple propagating Lamb waves as well as their attenuation. These results
are compared to simulation results in an inverse procedure to identify the parameters
of an elastic and a viscoelastic material model."

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: "Abstract\r\n 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."

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: The third‐order susceptibility of lithium
niobate (LiNbO3) is calculated within a Berry‐phase formulation
of the dynamical polarization based on the electronic structure obtained within
density‐functional theory (DFT). Maximum values of the order of m V are calculated
for photon energies between 1.2 and 2 eV, i.e., in the lower half of the optical
bandgap of lithium niobate. Both free and bound electron (bi)polarons are found
to lead to a remarkable enhancement of the third‐order susceptibility for photon
energies below 1 eV.
