text: AbstractWe consider the problem of maximization
of metabolite production in bacterial cells formulated as a dynamical optimal
control problem (DOCP). According to Pontryagin’s maximum principle, optimal solutions
are concatenations of singular and bang arcs and exhibit the chattering or Fuller
phenomenon, which is problematic for applications. To avoid chattering, we introduce
a reduced model which is still biologically relevant and retains the important
structural features of the original problem. Using a combination of analytical
and numerical methods, we show that the singular arc is dominant in the studied
DOCPs and exhibits the turnpike property. This property
is further used in order to design simple and realistic suboptimal control strategies.

text: "Algorithm configuration (AC) is concerned with the automated search of the\r\nmost
suitable parameter configuration of a parametrized algorithm. There is\r\ncurrently
a wide variety of AC problem variants and methods proposed in the\r\nliterature.
Existing reviews do not take into account all derivatives of the AC\r\nproblem,
nor do they offer a complete classification scheme. To this end, we\r\nintroduce
taxonomies to describe the AC problem and features of configuration\r\nmethods,
respectively. We review existing AC literature within the lens of our\r\ntaxonomies,
outline relevant design choices of configuration approaches,\r\ncontrast methods
and problem variants against each other, and describe the\r\nstate of AC in industry.
Finally, our review provides researchers and\r\npractitioners with a look at future
research directions in the field of AC."

text: Federkraftbremsen sind weit verbreitete Komponenten der Antriebstechnik, ansteigend
mit abnehmender Größe erreichen sie aktuell Drehzahlen von bis zu 5 000 min−1.
Es besteht ein Trend zu schnell laufenden Antrieben, mit Drehzahlen von 10 000
min−1 und darüber. Bisher sind wenig Kenntnisse über das Verhalten des Reibwerts
und -moments herkömmlicher Federkraftbremsen mit kostengünstigen organischen Reibbelägen
bei diesen Einsatzbedingungen bekannt. Daher wurde ein Prüfstand entwickelt, der
die Untersuchung bei Gleitgeschwindigkeiten von bis zu 50 m/s bei verschiedenen
Lastträgheiten ermöglicht. Die Versuche zeigten, dass bei begrenzten Reibarbeiten
die herkömmliche Federkraftbremse durchaus das Nennbremsmoment bei höheren Gleitgeschwindigkeiten
erreicht.

text: "Context: The implementation of successful measures to support immigrants'
integration in cultural, social, and economic life can be considered as one of
today's greatest challenges for many societies. This is especially true for adolescent
immigrants who have not yet been able to finish education or gain qualifications
relevant to joining the labour market. That is why many receiving countries have
developed and implemented special programmes that aim at supporting immigrants'
integration by facilitating their employability. Unfortunately, not much is known
about the process of implementing these programmes or about how education systems,
schools, and teachers are dealing with the new situation and target group. In
this contribution, the implementation, development, and challenges of German Vocational
Integration Classes (VIC), as an example of comparable programmes in the EU, are
investigated to address this research gap. The paper considers the following exploratory
research questions: (a) What challenges have been experienced by teachers and
social workers in the implementation of VIC as well as in the integration of immigrants
into the labour market in recent years? (b) How can these challenges be met in
the long run and how should VIC be developed to better achieve its aims? \r\n\r\nMethods:
To answer these questions, a sequential qualitative study containing questionnaire
and interview elements was conducted. First, teachers and social workers involved
in VIC filled in a questionnaire about their experiences and experienced challenges
in implementing VIC (N = 46). Then, supplementing interviews were conducted with
participants from the first sample in order to generate further insights and to
contextualise the findings from the first study part (N = 14). \r\n\r\nFindings:
From the respondents' answers, it appears that the VIC programme is well implemented.
The results show, however, that central challenges continue to exist. This concerns,
for example, legal regulations or the development of adequate curricula, but also
the scope and quality of language education. In addition, problems have also been
identified with regard to students' culture-specific education and their individual
attitudes. These prevailing problems seem to affect schooling and educational
processes. In addition, respondents report feeling left alone to deal with problems
and that their experiences from their daily work in VIC and with immigrants are
not sufficiently taken into account in policy and school-related decisions. \r\n\r\nConclusions:
Although VIC seems well implemented, key challenges remain in the view of the
participants. It was found that teachers cannot solve many of the identified problems
themselves, as they require action at the level of policy or school organisation.
For staff, this can be accompanied by increased stress and demotivation. For the
young immigrants, the existing challenges can have a long-term impact on school
success and transition to vocational education and training. The study thus highlights
the importance of targeted and holistic strategies to support immigrant integration
through education. "

text: "Abstract\r\n Batteries capable
of extreme fast-charging (XFC) are a necessity for the deployment of electric
vehicles. Material properties of electrodes and electrolytes along with cell parameters
such as stack pressure and temperature have coupled, synergistic, and sometimes
deleterious effects on fast-charging performance. We develop a new experimental
testbed that allows precise and conformal application of electrode stack pressure.
We focus on cell capacity degradation using single-layer pouch cells with graphite
anodes, LiNi0.5Mn0.3Co0.2O2 (NMC532) cathodes, and carbonate-based electrolyte.
In the tested range (10 – 125 psi), cells cycled at higher pressure show higher
capacity and less capacity fading. Additionally, Li plating decreases with increasing
pressure as observed with scanning electron microscopy (SEM) and optical imaging.
While the loss of Li inventory from Li plating is the largest contributor to capacity
fade, electrochemical and SEM examination of the NMC cathodes after XFC experiments
show increased secondary particle damage at lower pressure. We infer that the
better performance at higher pressure is due to more homogenous reactions of active
materials across the electrode and less polarization through the electrode thickness.
Our study emphasizes the importance of electrode stack pressure in XFC batteries
and highlights its subtle role in cell conditions."
