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.

text: '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 $L_d$
that is modelled as a neural network. Careful regularisation of the loss function
for training $L_d$ 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.'

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: The numerical solution of an ordinary differential equation can be interpreted
as the exact solution of a nearby modified equation. Investigating the behaviour
of numerical solutions by analysing the modified equation is known as backward
error analysis. If the original and modified equation share structural properties,
then the exact and approximate solution share geometric features such as the existence
of conserved quantities. Conjugate symplectic methods preserve a modified symplectic
form and a modified Hamiltonian when applied to a Hamiltonian system. We show
how a blended version of variational and symplectic techniques can be used to
compute modified symplectic and Hamiltonian structures. In contrast to other approaches,
our backward error analysis method does not rely on an ansatz but computes the
structures systematically, provided that a variational formulation of the method
is known. The technique is illustrated on the example of symmetric linear multistep
methods with matrix coefficients.

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."

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 a miniaturized pulse shaping device that creates an arbitrary dispersion
through the interaction of multiple metasurfaces on less than 2 mm3
volume. For this, a metalens and a grating-metasurface between two silver mirrors
are fabricated. The grating contains further phase information to achieve the
device's pulse shaping functionality.

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.

text: "\r\nPurpose\r\nThe
purpose of this study is to investigate the manufacturability of Fe-3Si lattice
structures and the resulting mechanical properties. This study could lead to the
successful processing of squirrel cage conductors (a lattice structure by design)
of an induction motor by additive manufacturing in the future.\r\n\r\n\r\nDesign/methodology/approach\r\nThe
compression behaviour of two lattice structures where struts are arranged in a
face-centred cubic position and vertical edges (FCCZ), and struts are placed at
body-centred cubic (BCC) positions, prepared by laser powder bed fusion (LPBF),
is explored. The experimental investigations are supported by finite element method
(FEM) simulations.\r\n\r\n\r\nFindings\r\nThe
FCCZ lattice structure presents a peak in the stress-strain curve, whereas the
BCC lattice structure manifests a plateau. The vertical struts aligned along the
compression direction lead to a significant increase in the load-carrying ability
of FCCZ lattice structures compared to BCC lattice structures. This results in
a peak in the stress-strain curve. However, the BCC lattice structure presents
the bending of struts with diagonal struts carrying the major loads with struts
near the faceplate receiving the least load. A high concentration of geometrically
necessary dislocations (GNDs) near the grain boundaries along cell formation is
observed in the microstructure.\r\n\r\n\r\nOriginality/value\r\nTo
the best of the authors’ knowledge, this is the first study on additive manufacturing
of Fe-3Si lattice structures. Currently, there are no investigations in the literature
on the manufacturability and mechanical properties of Fe-3Si lattice structures.\r\n"

text: "Purpose: Data integration and applications across knowledge graphs (KGs)
rely heavily on the discovery of links between resources within these KGs. Geospatial
link discovery algorithms have to deal with millions of point sets containing
billions of points. \r\nMethodology: To speed up the discovery of geospatial links,
we propose COBALT. COBALT combines the content measures with R-tree indexing.
The content measures are based on the area, diagonal and distance of the minimum
bounding boxes of the polygons which speeds up the process but is not perfectly
accurate. We thus propose two polygon splitting approaches for improving the accuracy
of COBALT. \r\nFindings: Our experiments on real-world datasets show that COBALT
is able to speed up the topological relation discovery over geospatial KGs by
up to 1.47 × 104 times over state-of-the-art linking algorithms while maintaining
an F-Measure between 0.7 and 0.9 depending on the relation. Furthermore, we were
able to achieve an F-Measure of up to 0.99 by applying our polygon splitting approaches
before applying the content measures. \r\nValue: The process of discovering links
between geospatial resources can be significantly faster by sacrificing the optimality
of the results. This is especially important for real time data-driven applications
such as emergency response, location-based services and traffic management. In
future work, additional measures, like the location of polygons or the name of
the entity represented by the polygon, could be integrated to further improve
the accuracy of the results."

text: Linked knowledge graphs build the backbone of many data-driven applications
such as search engines, conversational agents and e-commerce solutions. Declarative
link discovery frameworks use complex link specifications to express the conditions
under which a link between two resources can be deemed to exist. However, understanding
such complex link specifications is a challenging task for non-expert users of
link discovery frameworks. In this paper, we address this drawback by devising
NMV-LS, a language model-based verbalization approach for translating complex
link specifications into natural language. NMV-LS relies on the results of rule-based
link specification verbalization to apply continuous training on T5, a large language
model based on the Transformerarchitecture. We evaluated NMV-LS on English and
German datasets using well-known machine translation metrics such as BLUE, METEOR,
ChrF++ and TER. Our results suggest that our approach achieves a verbalization
performance close to that of humans and outperforms state of the art approaches.
Our source code and datasets are publicly available at https://github.com/dice-group/NMV-LS.

text: "Purpose: This study addresses the limitations of current short abstracts
of DBpedia entities, which often lack a comprehensive overview due to their creating
method (i.e., selecting the first two-three sentences from the full DBpedia abstracts).\r\nMethodology:
We leverage pre-trained language models to generate abstractive summaries of DBpedia
abstracts in six languages (English, French, German, Italian, Spanish, and Dutch).
We performed several experiments to assess the quality of generated summaries
by language models. In particular, we evaluated the generated summaries using
human judgments and automated metrics (Self-ROUGE and BERTScore). Additionally,
we studied the correlation between human judgments and automated metrics in evaluating
the generated summaries under different aspects: informativeness, coherence, conciseness,
and fluency.\r\nFindings: Pre-trained language models generate summaries more
concise and informative than existing short abstracts. Specifically, BART-based
models effectively overcome the limitations of DBpedia short abstracts, especially
for longer ones.\r\nMoreover, we show that BERTScore and ROUGE-1 are reliable
metrics for assessing the informativeness and coherence of the generated summaries
with respect to the full DBpedia abstracts. We also find a negative correlation
between conciseness and human ratings. Furthermore, fluency evaluation remains
challenging without human judgment.\r\nValue: This study has significant implications
for various applications in machine learning and natural language processing that
rely on DBpedia resources. By providing succinct and comprehensive summaries,
our approach enhances the quality of DBpedia abstracts and contributes to the
semantic web community"

text: Graffiti is an urban phenomenon that is increasingly attracting the interest
of the sciences. To the best of our knowledge, no suitable data corpora are available
for systematic research until now. The Information System Graffiti in Germany
project (Ingrid) closes this gap by dealing with graffiti image collections that
have been made available to the project for public use. Within Ingrid, the graffiti
images are collected, digitized and annotated. With this work, we aim to support
the rapid access to a comprehensive data source on Ingrid targeted especially
by researchers. In particular, we present IngridKG, an RDF knowledge graph of
annotated graffiti, abides by the Linked Data and FAIR principles. We weekly update
IngridKG by augmenting the new annotated graffiti to our knowledge graph. Our
generation pipeline applies RDF data conversion, link discovery and data fusion
approaches to the original data. The current version of IngridKG contains 460,640,154
triples and is linked to 3 other knowledge graphs by over 200,000 links. In our
use case studies, we demonstrate the usefulness of our knowledge graph for different
applications.

text: Multiprotein adsorption from complex body fluids represents a highly
important and complicated phenomenon in medicine. In this work, multiprotein adsorption
from diluted human serum at gold and oxidized iron surfaces is investigated at
different serum concentrations and pH values. Adsorption-induced changes in surface
topography and the total amount of adsorbed proteins are quantified by atomic
force microscopy (AFM) and polarization-modulation infrared reflection absorption
spectroscopy (PM-IRRAS), respectively. For both surfaces, stronger protein adsorption
is observed at pH 6 compared to pH 7 and pH 8. PM-IRRAS furthermore provides some
qualitative insights into the pH-dependent alterations in the composition of the
adsorbed multiprotein films. Changes in the amide II/amide I band area ratio and
in particular side-chain IR absorption suggest that the increased adsorption at
pH 6 is accompanied by a change in protein film composition. Presumably, this
is mostly driven by the adsorption of human serum albumin, which at pH 6 adsorbs
more readily and thereby replaces other proteins with lower surface affinities
in the resulting multiprotein film.

text: The influence of nanoscale surface topography on protein adsorption
is highly important for numerous applications in medicine and technology. Herein,
ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces
is investigated using atomic force microscopy and X-ray photoelectron spectroscopy.
The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers
at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like
surface topographies with periodicities of about 160 nm and amplitudes of about
15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed
compared to the flat surface at a concentration of 10 mg/mL, which is attributed
to lower adsorption affinities of the newly formed facets. Consequently, adsorption
is restricted mostly to the pattern grooves, where the proteins can maximize their
contact area with the surface. However, this effect depends on the protein concentration,
with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin
adsorption behavior is observed at topographically similar nanofacet patterns
fabricated at different annealing temperatures and attributed to different step
and kink densities. These results demonstrate that while protein adsorption at
solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein
adsorption in this way requires the precise control of facet properties.

text: Indonesian is classified as underrepresented in the Natural Language Processing
(NLP) field, despite being the tenth most spoken language in the world with 198
million speakers. The paucity of datasets is recognized as the main reason for
the slow advancements in NLP research for underrepresented languages. Significant
attempts were made in 2020 to address this drawback for Indonesian. The Indonesian
Natural Language Understanding (IndoNLU) benchmark was introduced alongside IndoBERT
pre-trained language model. The second benchmark, Indonesian Language Evaluation
Montage (IndoLEM), was presented in the same year. These benchmarks support several
tasks, including Named Entity Recognition (NER). However, all NER datasets are
in the public domain and do not contain domain-specific datasets. To alleviate
this drawback, we introduce IndQNER, a manually annotated NER benchmark dataset
in the religious domain that adheres to a meticulously designed annotation guideline.
Since Indonesia has the world’s largest Muslim population, we build the dataset
from the Indonesian translation of the Quran. The dataset includes 2475 named
entities representing 18 different classes. To assess the annotation quality of
IndQNER, we perform experiments with BiLSTM and CRF-based NER, as well as IndoBERT
fine-tuning. The results reveal that the first model outperforms the second model
achieving 0.98 F1 points. This outcome indicates that IndQNER may be an acceptable
evaluation metric for Indonesian NER tasks in the aforementioned domain, widening
the research’s domain range.

text: 'AbstractExternal visualization (i.e., physically
embodied visualization) is central to the teaching and learning of mathematics.
As external visualization is an important part of mathematics at all levels of
education, it is diverse, and research on external visualization has become a
wide and complex field. The aim of this scoping review is to characterize external
visualizations in recent mathematics education research in order to develop a
common ground and guide future research. A qualitative content analysis of the
full texts of 130 studies published between 2018 and 2022 applied a deductive-inductive
coding procedure to assess four dimensions: visualization product or process,
type of visualization, media, and purpose. The analysis revealed different types
of external visualizations including visualizations with physical resemblance
ranging from pictorial to abstract visualizations as well as three types of visualizations
with structural resemblance: length, area, and relational visualizations. Future
research should include measures of visualization products or processes to help
explain the demands and affordances that different types of visualizations present
to learners and teachers.'
