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 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: "The principle of least action is one of the most fundamental physical principle.
It says that among all possible motions connecting two points in a phase space,
the system will exhibit those motions which extremise an action functional. Many
qualitative features of dynamical systems, such as the presence of conservation
laws and energy balance equations, are related to the existence of an action functional.
Incorporating variational structure into learning algorithms for dynamical systems
is, therefore, crucial in order to make sure that the learned model shares important
features with the exact physical system. In this paper we show how to incorporate
variational principles into trajectory predictions of learned dynamical systems.
The novelty of this work is that (1) our technique relies only on discrete position
data of observed trajectories. Velocities or conjugate momenta do not need to
be observed or approximated and no prior knowledge about the form of the variational
principle is assumed. Instead, they are recovered using backward error analysis.
(2) Moreover, our technique compensates discretisation errors when trajectories
are computed from the learned system. This is important when moderate to large
step-sizes are used and high accuracy is required. For this,\r\nwe introduce and
rigorously analyse the concept of inverse modified Lagrangians by developing an
inverse version of variational backward error analysis. (3) Finally, we introduce
a method to perform system identification from position observations only, based
on variational backward error analysis."

text: "Recently, Hamiltonian neural networks (HNN) have been introduced to incorporate
prior physical knowledge when\r\nlearning the dynamical equations of Hamiltonian
systems. Hereby, the symplectic system structure is preserved despite\r\nthe data-driven
modeling approach. However, preserving symmetries requires additional attention.
In this research, we\r\nenhance the HNN with a Lie algebra framework to detect
and embed symmetries in the neural network. This approach\r\nallows to simultaneously
learn the symmetry group action and the total energy of the system. As illustrating
examples,\r\na pendulum on a cart and a two-body problem from astrodynamics are
considered."

description: |-
Incorporating physical system knowledge into data-driven
system identification has been shown to be beneficial. The
approach presented in this article combines learning of an
energy-conserving model from data with detecting a Lie
group representation of the unknown system symmetry.
The proposed approach can improve the learned model
and reveal underlying symmetry simultaneously.

text: Dieser Beitrag bietet verschiedene professionelle Perspektiven auf den popmusikalischen
Kommunikationsprozesses innerhalb postdigitaler Popmusikjournalismuskulturen.
Neben einer wissenschaftlichen Rahmung, Übersicht und Strukturierung des Untersuchungsfelds
und des Forschungsstands versammelt der Beitrag multiperspektivische Thesen, die
journalistische Praktiken und ihre Reflexionen von Produktion über Distribution
und Rezeption/Nutzung bis zur Weiterverarbeitung inklusive Archivierung/Institutionalisierung/Musealisierung
aufgreifen und herausstellen. Die aufgestellten Thesen gelten als Aufschlag für
die zukünftige Analyse des so fundamentalen und doch auch immer wieder übersehenen
Berufsfeldes und seiner Rezeption zwischen Faszination und Exploitation.

text: Abstract. Increasing resource efficiency is a major challenge and
affects almost every aspect of social and economic life. The mobility sector in
particular is responsible for a large share of primary energy consumption and
is increasingly in the focus of public interest. One possibility to adress these
challenges is to reduce the vehicle weight by means of lightweight construction
technologies such as multi-material systems. These assemblies consist of workpieces
with different mechanical and geometrical properties, which poses a major challenge
for joining technology. Mechanical joining processes such as semi-tubular self-piercing
riveting are often used in the production of these assemblies, but due to their
process characteristics, they are rigid and can only react to changing process
variables to a limited extent. One way to increase the versatility of self-piercing
riveting is to superimpose a tumbling kinematics on the punch. During tumbling,
an angular offset of the punch axis to the tool axis is set and the contact area
between punch and workpiece is reduced. In this work, investigations were carried
out to determine how the tumbling strategy, consisting of the parameters tumbling
angle, tumbling onset and tumbling kinematics, affects the material flow of the
rivet element. For this purpose, experimental tests are conducted with the typical
materials of conventional multi-material systems and the geometric joint formations
are determined by means of macrographs.

text: "Ever increasing demands on the performance of microchips are leading to ever
more complex semiconductor technologies with ever shrinking feature sizes. Complex
applications with high demands on safety and reliability, such as autonomous driving,
are simultaneously driving the requirements for test and diagnosis of VLSI circuits.
Throughout the life cycle of a microchip, uncertainties occur that affect its
timing behavior. For example, weak circuit structures, aging effects, or process
variations can lead to a change in the timing behavior of the circuit. While these
uncertainties do not necessarily lead to a change of the functional behavior,
they can lead to a reliability problem.\r\nWith modular and hybrid compaction
two test instruments are presented in this work that can be used for X-tolerant
test response compaction in the built-in Faster-than-At-Speed Test (FAST) which
is used to detect uncertainties in VLSI circuits. One challenge for test response
compaction during FAST is the high and varying X-rate at the outputs of the circuit
under test. By dividing the circuit outputs into test groups and separately compacting
these test groups using stochastic compactors, the modular compaction is able
to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic
interconnects, a method for distinguishing crosstalk and process variation is
presented. In current semiconductor technologies, the number of parasitic coupling
capacitances between logic interconnects is growing. These coupling capacitances
can lead to crosstalk, which causes increased current flow in the logic interconnects,
which in turn can lead to increased electromigration. In the presented method,
delay maps describing the timing behavior of the circuit outputs at different
operating points are used to train artificial neural networks which classify the
tested circuits into fault-free and faulty."

zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen. Anwendungen
mit hohen Ansprüchen an Sicherheit und Zuverlässigkeit, wie z.B. das autonome
Fahren, treiben gleichzeitig die Anforderungen an den Test hochintegrierter Schaltungen
an. Während des gesamten Lebenszyklus eines Mikrochips kommt es zu Unsicherheiten
im Zeitverhalten. So können z.B. schwache Schaltungsstrukturen, Alterungseffekte
oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während
diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen
müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der
modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente
vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest
verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung
während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den
Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge
in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen
Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden
X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen
der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und
Prozessvariation vorgestellt. In aktuellen Halbleitertechnologien kommt es vermehrt
zu parasitären Koppelkapazitäten zwischen den Verbindungsleitungen. In dem vorgestellten
Verfahren werden künstliche neuronale Netze trainiert, um die Schaltungen in fehlerfrei
und fehlerhaft zu klassifizieren."

text: We present the fabrication of strain-free quantum dots in the In0.53Ga0.47As/In0.52Al0.48As-system
lattice matched to InP, as future sources for single and entangled photons for
long-haul fiber-based quantum communication in the optical C-band. We achieved
these quantum dots by local droplet etching via InAl droplets in an In0.52Al0.48As
layer and subsequent filling of the holes with In0.53Ga0.47As. Here, we present
detailed investigations of the hole morphologies measured by atomic force microscopy.
Statistical analysis of a set of nanoholes reveals a high degree of symmetry for
nearly half of them when etched at optimized temperatures. Overgrowth with 50–150 nm
In0.52Al0.48As increases their diameter and elongates the holes along the [01̄1]-direction.
By systematically scanning the parameter space, we were able to fill the holes
with In0.53Ga0.47As, and by capping the filled holes and performing photoluminescence
measurements, we observe photoluminescence emission in the O-band up into the
C-band depending on the filling height of the nanoholes.
