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: "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: We study the effect of education on health (hospital stays, number of diagnosed
conditions, self-rated poor health, and obesity) over the life-cycle in Germany,
using compulsory schooling reforms as a source of exogenous variation. Our results
suggest a positive correlation of health and education which increases over the
life-cycle. We do not, however, find any positive local average treatment effects
of an additional year of schooling on health or health care utilization for individuals
up to age 79. An exception is obesity, where positive effects of schooling start
to be visible around age 60 and become very large in age group 75-79. The results
in age group 75-79 need to be interpreted with caution, however, due to small
sample size and possible problems of attrition.

text: "The Koopman operator has become an essential tool for data-driven analysis,
prediction and control of complex systems, the main reason being the enormous
potential of identifying linear function space representations of nonlinear\r\ndynamics
from measurements. Until now, the situation where for large-scale systems, we
(i) only have access to partial observations (i.e., measurements, as is very common
for experimental data) or (ii) deliberately perform coarse\r\ngraining (for efficiency
reasons) has not been treated to its full extent. In this paper, we address the
pitfall associated with this situation, that the classical EDMD algorithm does
not automatically provide a Koopman operator approximation for the underlying
system if we do not carefully select the number of observables. Moreover, we show
that symmetries in the system dynamics can be carried over to the Koopman operator,
which allows us to massively increase the model efficiency. We also briefly draw
a connection to domain decomposition techniques for partial differential equations
and present numerical evidence using the Kuramoto--Sivashinsky equation."

text: We study the effect of education on vaccination against COVID-19 and influenza
in Germany and Europe. Our identification strategy makes use of changes in compulsory
schooling laws and allows to estimate local average treatment effects for individuals
between 59 and 91 years of age. We find no significant effect of an additional
year of schooling on vaccination status in Germany. Pooling data from Europe,
we conclude that schooling increases the likelihood to vaccinate against COVID
by an economically negligible effect of one percentage point (zero for influenza).
However, we find indications that additional schooling increases fear of side
effects from COVID vaccination.
