text: 'State-of-the-art LLC resonant converters use MOSFETs in their inverter stage,
which allows high switching frequencies and thus the use of compact magnetic components.
The large parasitic output capacitance and the poor reverse-recovery behaviour
of the inherent body diode of high-voltage (600 V) silicon MOSFETs require soft
switching, i.e. zero-voltage switching (ZVS). Otherwise, the high turn-on switching
losses would lead to excessive heating and ultimately to the destruction of the
switch. Therefore, MOSFET-based LLC converters are operated in the so-called inductive
region only, which enables ZVS. The use of robust and cost-effective IGBTs instead
of MOSFETs is particularly advantageous for automotive applications, since in
addition to high reliability low costs are an important objective here. Since
IGBTs are characterized by dominant turn-off losses and generally higher switching
losses compared to MOSFETs, the aim is to operate them with zero-current switching
(ZCS) and at low switching frequencies below the resonance frequency. In this
region also the voltage transfer characteristic is steeper, which qualifies for
applications with a strongly varying input-to-output voltage ratio, such as given
for automotive on-board DC-DC converters connecting the (high-voltage) traction
battery with the (12 V) auxiliary battery. In this paper, a stress value analysis
based on a switched-model simulation is used to design a ZCS LLC converter and
take advantage of the mentioned benefits of IGBTs as well as of the steeper voltage
transfer characteristic. Within this operation region below the resonance frequency,
however, a new phenomenon of several current pulses occurring during a single
switching period through the rectifier components may appear. Generally, in applications
with high output currents a synchronous rectifier (SR) is often used to keep the
conduction losses of the rectifier stage at a moderate level: Low-voltage MOSFETs,
which actively need to be gated synchronously to the polarity of the current pulses,
are employed then instead of more lossy rectifier diodes. However, standard SR
driver ICs have been shown to be unable to properly rectify the multi-pulse output
currents of the proposed LLC operation, resulting in high conduction losses of
the rectifier stage. A cost-effective hardware concept is presented which ensures
proper rectification by using standard SR-ICs that are actively overdriven by
the converter’s central microcontroller. A 2 kW prototype for an EV on-board DC-DC
converter was built to show the effectiveness of the method, documenting an increase
in efficiency by up to 4.1 % compared to a purely SR-IC-based solution. Overall
efficiency is very similar to that of a conventional (MOSFET-based) LLC converter
so that the ZCS-operated LLC IGBT-converter represents a cost-effective alternative,
which even shows 10 % less worst-case losses.'

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: The non-orthogonal local submatrix method applied to electronic structure–based
molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32-mixed
floating-point arithmetic when using 4400 NVIDIA A100 GPUs of the Perlmutter system.
This is enabled by a modification of the original method that pushes the sustained
fraction of the peak performance to about 80%. Example calculations are performed
for SARS-CoV-2 spike proteins with up to 83 million atoms.

text: 'Site-controlled Ga droplets on AlGaAs substrates are fabricated using
area-selective deposition of Ga through apertures in a mask during molecular beam
epitaxy (MBE). The Ga droplets can be crystallized into GaAs quantum dots using
a crystallization step under As flux. In order to model the complex process, including
the masked deposition of the droplets and a reduction of their number during a
thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of
self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition.
The simulation has only two free model parameters: the activation energy for surface
diffusion and the activation energy for thermal escape of adatoms from a droplet.
Simulated droplet numbers within the opening of the aperture agree quantitatively
with the experimental results down to the perfect site-control, with one droplet
per aperture. However, the model parameters are different compared to those of
the self-assembled droplet growth. We attribute this to the presence of the mask
in close proximity to the surface, which modifies the local process temperature
and the As background. This approach also explains the dependence of the model
parameters on the size of the aperture.'

text: "Effect chain modelling is a method for creating information\r\nmodels for
impact analyses of changes in system elements. For\r\nthe estimation of change
propagation, dependencies between\r\nrequirements must be detected. The high number
of require-\r\nment dependencies in the engineering of complex technical\r\nsystems
results in the need for automation. In a study, it was\r\nshown that transformer
models (BERT) are suitable for the\r\nautomated dependency analysis of requirements.
However,\r\nthere are currently deficits in the applicability of the models\r\nfor
different projects without an extensive and heterogeneous\r\ntraining database.
This paper investigates how active learning\r\ncan be used to train BERT models
(active-BERT) in order to\r\nincrease the performance of the models for classifying
requi-\r\nrement dependencies of projects with heterogeneous require-\r\nments.
The results show that the performance of the models\r\nincreases significantly
through active learning. Through active-\r\nBERT, engineers are enabled to model
effect chains efficiently\r\nand to handle requirement changes effectively."

text: Effective photoinduced charge transfer makes molecular bimetallic assemblies
attractive for applications as active light induced proton reduction systems.
For a more sustainable future, development of competitive base metal dyads is
mandatory. However, the electron transfer mechanisms from the photosensitizer
to the proton reduction catalyst in base metal dyads remain so far unexplored.
We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using
femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy
and theoretical time-dependent DFT calculations, to understand the electronic
and structural dynamics after photoexcitation and during the subsequent charge
transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using
this novel approach, the simultaneous measurement of the transient Kalpha X-ray
emission at the iron and cobalt K-edges in a two-colour experiment is enabled
making it possible to correlate the excited state dynamics to the electron transfer
processes. The methodology, therefore, provides a clear and direct spectroscopic
evidence of the Fe->Co electron transfer responsible for the proton reduction
activity.

The principle of least action is one of the most fundamental physical principle. It says that among all possible motions
