text: In order to standardize spray flame synthesis (SFS) studies, intensive work
has been done in recent years on the design of burner types. Thus, in 2019, the
so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized
in numerical and experimental studies. Based on this research, a modification
of the nozzle design was proposed, which has now been considered in the successor
model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation
on the particle formation, we operated both burners under identical operating
conditions to produce maghemite. The final powder comparison showed that SS2 yielded
considerable higher specific surface areas (associated with smaller primary particle
sizes), lower polydispersity, and higher phase purity. To obtain further information
on the size distributions of aggregates and agglomerates generated by SS2, aerosol
samples were extracted by hole in a tube (HIAT) sampling and characterized by
scanning mobility particle sizing (SMPS). Samples were extracted along the centerline
at different heights above the burner (HAB) above the visible flame tip (>7 cm),
and quenching experiments were performed to extract the aerosol samples at different
dilution rates. Thereby, it was demonstrated that performing detailed quenching
experiments is crucial for obtaining representative HIAT-SMPS data. In particular,
agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were
not sufficiently diluted. If sufficient dilution was applied, distribution widths
and mean particle mobility diameters were determined with high accuracy (sample
standard derivation <5 %). Our data suggested the evolution of primary particle
sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates
present above the visible flame were compact in structure (non- fractal). The
mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7
cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.

text: Algorithmic fairness in Information Systems (IS) is a concept that aims to
mitigate systematic discrimination and bias in automated decision-making. However,
previous research argued that different fairness criteria are often incompatible.
In hiring, AI is used to assess and rank applicants according to their fit for
vacant positions. However, various types of bias also exist for AI-based algorithms
(e.g., using biased historical data). To reduce AI’s bias and thereby unfair treatment,
we conducted a systematic literature review to identify suitable strategies for
the context of hiring. We identified nine fundamental articles in this context
and extracted four types of approaches to address unfairness in AI, namely pre-process,
in-process, post-process, and feature selection. Based on our findings, we (a)
derived a research agenda for future studies and (b) proposed strategies for practitioners
who design and develop AIs for hiring purposes.

text: "We study how competition between physicians affects the provision of medical
care. In\r\nour theoretical model, physicians are faced with a heterogeneous patient
population, in which patients\r\nsystematically vary with regard to both their
responsiveness to the provided quality of care and their\r\nstate of health. We
test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment.
In line with the model, we observe that competition significantly improves patient
benefits\r\nas long as patients are able to respond to the quality provided. For
those patients, who are not able\r\nto choose a physician, competition even decreases
the patient benefit compared to a situation without\r\ncompetition. This decrease
is in contrast to our theoretical prediction implying no change in benefits for\r\npassive
patients. Deviations from patient-optimal treatment are highest for passive patients
in need of\r\na low quantity of medical services. With repetition, both, the positive
effects of competition for active\r\npatients as well as the negative effects
of competition for passive patients become more pronounced. Our\r\nresults imply
that competition can not only improve but also worsen patient outcome and that
patients’\r\nresponsiveness to quality is decisive."

text: "We propose a diarization system, that estimates “who spoke when” based on
spatial information, to be used as a front-end of a meeting transcription system
running on the signals gathered from an acoustic sensor network (ASN). Although
the\r\nspatial distribution of the microphones is advantageous, exploiting the
spatial diversity for diarization and signal enhancement is challenging, because
the microphones’ positions are typically unknown, and the recorded signals are
initially unsynchronized in general. Here, we approach these issues by first blindly
synchronizing the signals and then estimating time differences of arrival (TDOAs).
The TDOA information is exploited to estimate the speakers’ activity, even in
the presence of multiple speakers being simultaneously active. This speaker activity
information serves as a guide for a spatial mixture model, on which basis the
individual speaker’s signals are extracted via beamforming. Finally, the extracted
signals are forwarded to a speech recognizer. Additionally, a novel initialization
scheme for spatial mixture models based on the TDOA estimates is proposed. Experiments
conducted on real recordings from the LibriWASN data set have shown that our proposed
system is advantageous compared to a system using a spatial mixture model, which
does not make use\r\nof external diarization information."

text: The security of Industrial Control Systems is relevant both for reliable production
system operations and for high-quality throughput in terms of manufactured products.
Security measures are designed, operated and maintained by different roles along
product and production system lifecycles. Defense-in-Depth as a paradigm builds
upon the assumption that breaches are unavoidable. The paper at hand provides
an analysis of roles, corresponding Human Factors and their relevance for data
theft and sabotage attacks. The resulting taxonomy is reflected by an example
related to Additive Manufacturing. The results assist in both designing and redesigning
Industrial Control System as part of an entire production system so that Defense-in-Depth
with regard to Human Factors is built in by design.

text: Optimal decision making requires appropriate evaluation of advice. Recent
literature reports that algorithm aversion reduces the effectiveness of predictive
algorithms. However, it remains unclear how people recover from bad advice given
by an otherwise good advisor. Previous work has focused on algorithm aversion
at a single time point. We extend this work by examining successive decisions
in a time series forecasting task using an online between-subjects experiment
(N = 87). Our empirical results do not confirm algorithm aversion immediately
after bad advice. The estimated effect suggests an increasing algorithm appreciation
over time. Our work extends the current knowledge on algorithm aversion with insights
into how weight on advice is adjusted over consecutive tasks. Since most forecasting
tasks are not one-off decisions, this also has implications for practitioners.

text: Verifying assertions is an essential part of creating and maintaining knowledge
graphs. Most often, this task cannot be carried out manually due to the sheer
size of modern knowledge graphs. Hence, automatic fact-checking approaches have
been proposed over the last decade. These approaches aim to compute automatically
whether a given assertion is correct or incorrect. However, most fact-checking
approaches are binary classifiers that fail to consider the volatility of some
assertions, i.e., the fact that such assertions are only valid at certain times
or for specific time intervals. Moreover, the few approaches able to predict when
an assertion was valid (i.e., time-point prediction approaches) rely on manual
feature engineering. This paper presents TEMPORALFC, a temporal fact-checking
approach that uses multiple sources of background knowledge to assess the veracity
and temporal validity of a given assertion. We evaluate TEMPORALFC on two datasets
and compare it to the state of the art in fact-checking and time-point prediction.
Our results suggest that TEMPORALFC outperforms the state of the art on the fact-checking
task by 0.13 to 0.15 in terms of Area Under the Receiver Operating Characteristic
curve and on the time-point prediction task by 0.25 to 0.27 in terms of Mean Reciprocal
Rank. Our code is open-source and can be found at https://github.com/dice-group/TemporalFC.

text: "The volume comprises a variety of research approaches that seek to explore
and understand employees’ learning and development through and for work. Working
life reveals challenges through technological, economic and societal development
that can only rudimentarily be addressed by formal education and training. Workplace
learning becomes more and more important for employees and enterprises to successfully
cope with these challenges.\r\nWorkplace learning is a steadily growing field
of educational research but it lacks so far a scholastic canon – there is rather
a diversity of research approaches. This volume reflects this diversity by bringing
together researchers from different countries and different theoretical backgrounds,
presenting their current research on topics that all are relevant for understanding
presages, processes and outcomes of workplace learning. Hence, this volume is
of relevance for researchers as well as practitioners in the field and policy
makers."

text: "We study the bargaining behavior between auditor and auditee in a tax setting
and scrutinize\r\nthe effect of interpersonal trust and trust in government on
both parties’ concessions.\r\nWe find evidence that both kinds of trust affect
the concessionary behavior, albeit\r\nin different ways. While trust in government
affects concessionary behavior in line with\r\nintuitive predictions, we find
that interpersonal trust only affects tax auditors. For high\r\ninterpersonal
trust, the alleviating effect of high trust in government on tax auditors’\r\nconcessions
is less pronounced. Our findings help tax authorities to shape programs to\r\nenhance
compliance in an atmosphere of trust."

text: "Force–displacement measurements and micrograph analyses are commonly used
methods to validate numerical models of clinching processes. However, these methods
often lead to resetting of elastic deformations and crack-\r\nclosing after unloading.
In contrast, the in situ computed tomography (CT) can provide three-dimensional
images of the clinch point under loading conditions. In this paper, the potential
of the in situ investigation of a clinching process as validation method is analyzed.
For the in situ testing, a tailored test set-up featuring a beryllium cylinder
for load-bearing and clinching tools made from ultra-high-strength titanium and
Si3N4 are used. In the experiments, the clinching of two aluminum sheets is interrupted
at specific process steps in order to perform the CT scans. It is shown that in
situ CT visualizes the inner geometry of the joint at high precision and that
this method is suitable to validate numerical models."

text: Transformation of Fe- and Cu-rich primary phase particles was studied in an
Al-Li-based alloy prepared by twin-roll casting. Thin foils for combined STEM
and SEM experiments were prepared by electrolytic twin-jet polishing. They were
in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS
electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and
SE detectors working both in composition and topographic modes. The resulting
structures were combined with EDS mapping performed directly in the heating holder.
Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C.
EDS maps acquired on the foil cooled down to room temperature show that Cu and
Fe are both still present in newly formed particles, most likely indicating the
presence of the Al7Cu2Fe phase.

text: Modern traffic control systems are key to cope with current and future traffic
challenges. In this paper information obtained from a microscopic traffic estimation
using various data sources is used to feed a new developed traffic control approach.
The presented method can control a traffic area with multiple traffic light systems
(TLS) reacting to individual road users and pedestrians. In contrast to widespread
green time extension techniques, this control selects the best phase sequence
by analyzing the current traffic state reconstructed in SUMO and its predicted
progress. To achieve this, the key aspect of the control strategy is to use Model
Predictive Control (MPC). In order to maintain realism for real world applications,
among other things, the traffic phase transitions are modelled in detail and integrated
within the prediction. For the efficiency, the approach incorporates a fuzzy logic
preselection of all phases reducing the computational effort. The evaluation itself
is able to be easily adjusted to focus on various objectives like low occupancies,
reducing waiting times and emissions, few number of phase transitions etc. determining
the best switching times for the selected phases. Exemplary traffic simulations
demonstrate the functionality of the MPC-based control and, in addition, some
aspects under development like the real-world communication network are also discussed.

text: 'Academics may actively respond to the expectations of the academic
status market, which have largely been shaped by the World University Rankings
(WURs). This study empirically examines how academics’ citation patterns have
changed in response to the rise of an “evaluation environment” in academia. We
regard the WURs to be a macro-level trigger for cementing a bibliometric-based
evaluation environment in academia. Our analyses of citation patterns in papers
published in two higher education journals explicitly considered three distinct
periods: the pre-WURs (1990–2003), the period of WURs implementation (2004–2010),
and the period of adaption to WURs (2011–2017). We applied the nonparametric Kaplan–Meier
method to compare first-citation speeds of papers published across the three periods.
We found that not only has first-citation speed become faster, but first-citation
probability has also increased following the emergence of the WURs. Applying Cox
proportional hazard models to first-citation probabilities, we identified journal
impact factors and third-party funding as factors influencing first-citation probability,
while other author- and paper-related factors showed limited effects. We also
found that the general effects of different factors on first-citation speeds have
changed with the emergence of the WURs. The findings expand our understanding
of the citation patterns of academics in the rise of WURs and provide practical
grounds for research policy as well as higher education policy.'

text: 'Over the last years, several approaches for the data-driven estimation of
expected possession value (EPV) in basketball and association football (soccer)
have been proposed. In this paper, we develop and evaluate PIVOT: the first such
framework for team handball. Accounting for the fast-paced, dynamic nature and
relative data scarcity of hand- ball, we propose a parsimonious end-to-end deep
learning architecture that relies solely on tracking data. This efficient approach
is capable of predicting the probability that a team will score within the near
future given the fine-grained spatio-temporal distribution of all players and
the ball over the last seconds of the game. Our experiments indicate that PIVOT
is able to produce accurate and calibrated probability estimates, even when trained
on a relatively small dataset. We also showcase two interactive applications of
PIVOT for valuing actual and counterfactual player decisions and actions in real-time.'

text: We contribute to the theoretical understanding of randomized search heuristics
for dynamic problems. We consider the classical vertex coloring problem on graphs
and investigate the dynamic setting where edges are added to the current graph.
We then analyze the expected time for randomized search heuristics to recompute
high quality solutions. The (1+1) Evolutionary Algorithm and RLS operate in a
setting where the number of colors is bounded and we are minimizing the number
of conflicts. Iterated local search algorithms use an unbounded color palette
and aim to use the smallest colors and, consequently, the smallest number of colors.
We identify classes of bipartite graphs where reoptimization is as hard as or
even harder than optimization from scratch, i.e., starting with a random initialization.
Even adding a single edge can lead to hard symmetry problems. However, graph classes
that are hard for one algorithm turn out to be easy for others. In most cases
our bounds show that reoptimization is faster than optimizing from scratch. We
further show that tailoring mutation operators to parts of the graph where changes
have occurred can significantly reduce the expected reoptimization time. In most
settings the expected reoptimization time for such tailored algorithms is linear
in the number of added edges. However, tailored algorithms cannot prevent exponential
times in settings where the original algorithm is inefficient.

text: In all fields, the significance of a reliable and accurate predictive model
is almost unquantifiable. With deep domain knowledge, models derived from first
principles typically outperforms other models in terms of reliability and accuracy.
When it may become a cumbersome or an unachievable task to build or validate such
models of complex (non-linear) systems, machine learning techniques are employed
to build predictive models. However, the accuracy of such techniques is not only
dependent on the hyper-parameters of the chosen algorithm, but also on the amount
and quality of data. This paper investigates the application of classical time
series forecasting approaches for the reliable prognostics of technical systems,
where black box machine learning techniques might not successfully be employed
given insufficient amount of data and where first principles models are infeasible
due to lack of domain specific data. Forecasting by analogy, forecasting by analytical
function fitting, an exponential smoothing forecasting method and the long short-term
memory (LSTM) are evaluated and compared against the ground truth data. As a case
study, the methods are applied to predict future crack lengths of riveted aluminium
plates under cyclic loading. The performance of the predictive models is evaluated
based on error metrics leading to a proposal of when to apply which forecasting
approach.

text: Dynamic optimization problems have gained significant attention in evolutionary
computation as evolutionary algorithms (EAs) can easily adapt to changing environments.
We show that EAs can solve the graph coloring problem for bipartite graphs more
efficiently by using dynamic optimization. In our approach the graph instance
is given incrementally such that the EA can reoptimize its coloring when a new
edge introduces a conflict. We show that, when edges are inserted in a way that
preserves graph connectivity, Randomized Local Search (RLS) efficiently finds
a proper 2-coloring for all bipartite graphs. This includes graphs for which RLS
and other EAs need exponential expected time in a static optimization scenario.
We investigate different ways of building up the graph by popular graph traversals
such as breadth-first-search and depth-first-search and analyse the resulting
runtime behavior. We further show that offspring populations (e. g. a (1 + {$\lambda$})
RLS) lead to an exponential speedup in {$\lambda$}. Finally, an island model using
3 islands succeeds in an optimal time of {$\Theta$}(m) on every m-edge bipartite
graph, outperforming offspring populations. This is the first example where an
island model guarantees a speedup that is not bounded in the number of islands.

text: Several important optimization problems in the area of vehicle routing can
be seen as variants of the classical Traveling Salesperson Problem (TSP). In the
area of evolutionary computation, the Traveling Thief Problem (TTP) has gained
increasing interest over the last 5 years. In this paper, we investigate the effect
of weights on such problems, in the sense that the cost of traveling increases
with respect to the weights of nodes already visited during a tour. This provides
abstractions of important TSP variants such as the Traveling Thief Problem and
time dependent TSP variants, and allows to study precisely the increase in difficulty
caused by weight dependence. We provide a 3.59-approximation for this weight dependent
version of TSP with metric distances and bounded positive weights. Furthermore,
we conduct experimental investigations for simple randomized local search with
classical mutation operators and two variants of the state-of-the-art evolutionary
algorithm EAX adapted to the weighted TSP. Our results show the impact of the
node weights on the position of the nodes in the resulting tour.
