text: This manuscript makes the claim of having computed the 9th Dedekind number,
D(9). This was done by accelerating the core operation of the process with an
efficient FPGA design that outperforms an optimized 64-core CPU reference by 95x.
The FPGA execution was parallelized on the Noctua 2 supercomputer at Paderborn
University. The resulting value for D(9) is 286386577668298411128469151667598498812366.
This value can be verified in two steps. We have made the data file containing
the 490 M results available, each of which can be verified separately on CPU,
and the whole file sums to our proposed value. The paper explains the mathematical
approach in the first part, before putting the focus on a deep dive into the FPGA
accelerator implementation followed by a performance analysis. The FPGA implementation
was done in Register-Transfer Level using a dual-clock architecture and shows
how we achieved an impressive FMax of 450 MHz on the targeted Stratix 10 GX 2,800
FPGAs. The total compute time used was 47,000 FPGA hours.

text: 'In basketball, an attacking player often plays a pass to one side while looking
to the other side. This head fake provokes a conflict in the observing opponent,
as the processing of the head orientation interferes with the processing of the
pass direction. Accordingly, responses to passes with head fakes are slower and
result in more errors than responses to passes without head fakes (head-fake effect).
The head-fake effect and structurally similar interference effects (e.g., Stroop
effect) are modulated by the frequency of conflicting trials. Previous studies
mostly applied a block-wise manipulation of proportion congruency. However, in
basketball (and also in other team sports), where different individual opponents
can be encountered, it might be important to take the individual frequency (e.g.,
20% vs. 80%) of these opponents into account. Therefore, the present study investigates
the possibility to quickly (i.e., on a trial-by-trial basis) reconfigure the response
behavior to different proportions of incongruent trials, which are contingent
on different basketball players. Results point out that participants indeed adapted
to the fake-frequency of different basketball players, which could be the result
of strategic adaptation processes. Multi-level analyses, however, indicate that
a substantial portion of the player-specific adaptation to fake frequencies is
accounted by episodic retrieval processes, suggesting that item-specific proportion
congruency effects can be explained in terms of stimulus-response binding and
retrieval: The head orientation (e.g., to the right) of a current stimulus retrieves
the last episode with the same head orientation including the response that was
part of this last episode. Thus, from a theoretical perspective, an attacking
player would provoke the strongest detrimental effect on an opponent if s/he repeats
the same head movement but changes the direction of the pass. Whether it is at
all possible to strategically apply this recommendation in practice needs still
to be answered.'

text: Systems Engineering is becoming increasingly important in the engineering
of complex technical systems. Its introduction is forcing companies to undertake
major transformation initiatives. As established change management approaches
show, the corporate culture is an important key criterion for success of transformation.
Therefore, when introducing Systems Engineering into an organization, transformation
initiatives must be tailored to an existing corporate culture or the corporate
culture itself must be changed in order to enable Systems Engineering. In literature
and in industrial practice, different approaches for assessment of corporate culture
exist. Within this research, a systematic literature review on methods and models
for corporate culture assessment is conducted. Core elements are collected and
combined with the fundamentals and success factors of Systems Engineering to develop
a model for corporate culture assessment. The developed model is applied to the
industrial practice of an ongoing Systems Engineering transformation of a large
car manufacturer. The results of the assessment are compared with the emerging
project challenges. Based on this model and its supporting tool and templates,
organizations and transformation leaders are enabled to rapidly obtain an orientation
of hindering or supporting currently established cultural aspects with regard
to Systems Engineering transformation and to provide a decision basis for further
measures.

text: AbstractCellular stress and ageing involve
an increase in crowding and aggregation of amylogenic proteins. We here investigate
if crowding is the intrinsic cause of aggregation and utilise a previously established
non-protein aggregation sensor, namely pseudoisocyanine chloride (PIC). PIC shows
fibrillization in cells into a highly fluorescent J-aggregated state and is sensitive
to crowding. Surprisingly, cell stress conditions stabilise the monomeric rather
than the aggregated state of PIC both in the cytoplasm and in stress granules.
Regarding the different physiochemical changes of the cytoplasm occurring upon
cell stress, involving volume reduction, phase separation and solidification,
the intrinsic crowding effect is not the key factor to drive associated self-assembly
processes.

text: Clean hydrogen is a key aspect of carbon neutrality, necessitating robust
methods for monitoring hydrogen concentration in critical infrastructures like
pipelines or power plants. While semiconducting metal oxides such as In2O3 can
monitor gas concentrations down to the ppm range, they often exhibit cross-sensitivity
to other gases like H2O. In this study, we investigated whether cyclic optical
illumination of a gas-sensitive In2O3 layer creates identifiable changes in a
gas sensor´s electronic resistance that can be linked to H2 and H2O concentrations
via machine learning. We exposed nanostructured In2O3 with a large surface area
of 95 m2 g-1 to H2 concentrations (0-800 ppm) and relative humidity (0-70%) under
cyclic activation utilizing blue light. The sensors were tested for 20 classes
of gas combinations. A support vector machine achieved classification rates up
to 92.0%, with reliable reproducibility (88.2 ± 2.7%) across five individual sensors
using 10-fold cross-validation. Our findings suggest that cyclic optical activation
can be used as a tool to classify H2 and H2O concentrations.

text: Large audio tagging models are usually trained or pre-trained on AudioSet,
a dataset that encompasses a large amount of different sound classes and acoustic
environments. Knowledge distillation has emerged as a method to compress such
models without compromising their effectiveness. There are many different applications
for audio tagging, some of which require a specialization to a narrow domain of
sounds to be classified. For these scenarios, it is beneficial to distill the
large audio tagger with respect to a specific subset of sounds of interest. A
method to prune a general dataset with respect to a target dataset is presented.
By distilling with such a specialized pruned dataset, we obtain a compressed model
with better classification accuracy in the specific target domain than with target-agnostic
distillation.

text: 'Clifford algebras are a natural extension of division algebras, including
real numbers, complex numbers, quaternions, and octonions. Previous research in
knowledge graph embeddings has focused exclusively on Clifford algebras of a specific
type, which do not include nilpotent base vectors—elements that square to zero.
In this work, we introduce a novel approach by incorporating nilpotent base vectors
with a nilpotency index of two, leading to a more general form of Clifford algebras
named degenerate Clifford algebras. This generalization to degenerate Clifford
algebras does allow for covering dual numbers and as such include translations
and rotations models under the same generalization paradigm for the first time.
We develop two models to determine the parameters that define the algebra: one
using a greedy search and another predicting the parameters based on neural network
embeddings of the input knowledge graph. Our evaluation on seven benchmark datasets
demonstrates that this incorporation of nilpotent vectors enhances the quality
of embeddings. Additionally, our method outperforms state-of-the-art approaches
in terms of generalization, particularly regarding the mean reciprocal rank achieved
on validation data. Finally, we show that even a simple greedy search can effectively
discover optimal or near-optimal parameters for the algebra.'

text: "Abstract\r\n In this study, we
develop a novel multi-fidelity deep learning approach that transforms low-fidelity
solution maps into high-fidelity ones by incorporating parametric space information
into an autoencoder architecture. This method’s integration of parametric space
information significantly reduces the amount of training data needed to effectively
predict high-fidelity solutions from low-fidelity ones. In this study, we examine
a two-dimensional steady-state heat transfer analysis within a heterogeneous materials
microstructure. The heat conductivity coefficients for two different materials
are condensed from a 101 \r\n \r\n
\ $$\\times $$\r\n \r\n ×\r\n
\ \r\n \r\n 101
grid to smaller grids. We then solve the boundary value problem on the coarsest
grid using a pre-trained physics-informed neural operator network known as Finite
Operator Learning (FOL). The resulting low-fidelity solution is subsequently upscaled
back to a 101 \r\n \r\n $$\\times
$$\r\n \r\n
\ ×\r\n \r\n \r\n
\ 101 grid using a newly designed enhanced autoencoder.
The novelty of the developed enhanced autoencoder lies in the concatenation of
heat conductivity maps of different resolutions to the decoder segment in distinct
steps. Hence the developed algorithm is named microstructure-embedded autoencoder
(MEA). We compare the MEA outcomes with those from finite element methods, the
standard U-Net, and an interpolation approach as an upscaling technique. Our analysis
shows that MEA outperforms these methods in terms of computational efficiency
and error on representative test cases. As a result, the MEA serves as a potential
supplement to neural operator networks, effectively upscaling low-fidelity solutions
to high-fidelity while preserving critical details often lost in traditional upscaling
methods, such as sharp interfaces features lost in the context of interpolation
approaches."

text: AbstractThe open-source parameter identification
tool ADAPT (A diversely applicable parameter identification Tool) is integrated
with a machine learning-based approach for start value prediction in order to
calibrate a Gurson–Tvergaard–Needleman (GTN) and a Lemaitre damage model. As representative
example case-hardened steel 16MnCrS5 is elaborated. An artificial neural network
(ANN) is initially trained by using load–displacement curves derived from simulations
of a boundary value problem—instead of using data generated for homogeneous states
of deformation at material point or one-element level—with varying material parameter
combinations. The ANN is then employed so as to predict sets of material parameters
that already provide close solutions to the experiment. These predicted parameter
sets serve as starting values for a subsequent multi-objective parameter identification
by using ADAPT. ADAPT allows for the consideration of input data from multiple
scales, including integral data such as load–displacement curves, full-field data
such as displacement and strain fields, and high-resolution experimental void
data at the micro-scale. The influence of each data set on prediction quality
is analyzed. Using various types of input data introduces additional information,
enhancing prediction accuracy. The validation is carried out with respect to experimental
void measurements of forward rod extruded parts. The results demonstrate, by incorporating
void measurements in the optimization process, that it is possible to improve
the quantitative prediction of ductile damage in the sense of void area fractions
by factor 28 in forward rod extrusion.
