Es ist eine glückliche Fügung, wenn gegen Ende eines Lebens noch Zeit und
Energie und genügend Erinnerungsfähigkeit vorhanden sind, eine Bilanz des
Lebens und des beruflichen Wirkens zu erstellen, damit nicht alles ins
Vergessen abgleitet, was einmal durchdacht, durchlebt und vielleicht auch
erduldet und erlitten wurde. Insbesondere soll auch der Glücksmomente gedacht
werden, die es bei Begegnungen und gemeinsamen Unternehmungen mit netten
Menschen, Berufskollegen und Mitarbeitern gab. Die Ausführungen erfolgten in
der Annahme, dass ein Berufsleben in einer politisch sehr bewegten Zeit,
außerdem in einer ungewöhnlichen Universitätsstadt, Gründe für eine
retrospektive Aufarbeitung von zeitgeschichtlichen Ereignissen sein könnten,
mit Höhen und Tiefen, Erfolgen und Misserfolgen. Leichter gesagt als getan! Es
zeigte sich, dass es selbst in Zeiten moderner Kommunikation schwer ist, alles
Wichtige in einen chronologischen Zusammenhang zu bringen. Wäre da nicht eine
Dokumentation vorhanden gewesen, die von einer technischen Assistentin so peu
à peu während des eigentlichen Arbeitsablaufes erstellt worden war. Und wären
da nicht akribisch gesammelte Einzeldokumente vorhanden gewesen. Und natürlich
dienten die Ergebnisse einer regen publizistischen Tätigkeit im Laufe vieler
Jahre dazu, diesen vorliegenden Bericht zu erstellen. Ein Positivum hat eine
solche Aufarbeitung auch für den Autor selbst. Er erkennt immer klarer die
Nuancen einer effektiven Tätigkeit auf wissenschaftlichem Gebiet und zugleich
das damit verbundene Fehlleiten von Energie und Zeit auf Nebenschauplätze und
schön erscheinende Spielwiesen. Möge diese historisch ausgerichtete Bilanz das
geneigte Interesse möglichst vieler Leser finden, die an einem Einblick in die
bewegten Zeiten der ständigen Reformen an den Universitäten in Berlin nach dem
Krieg, im Kalten Krieg und zu Zeiten der Wiedervereinigung interessiert sind!
Möge der Leser auch ab und an zum Schmunzeln animiert werden ob der
möglicherweise stark persönlich geprägten Interpretationen von Sachverhalten!
Auch datenschutzrechtliche Gesichtspunkte wurden, soweit es notwendig schien,
zu berücksichtigen versucht. Möge Vieles gefallen und nur wenig stören oder
irritieren! In diesem Sinne etwas Neugier und Interesse und auch etwas Freude
beim Einsteigen in einen Bericht aus einer bewegten Zeit
Antriebsstrang 2025 : „Energieeffiziente Prozessketten zur Herstellung eines reibungs-, gewichts- und lebensdaueroptimierten Antriebsstrangs“
Abschlussbericht zum BMWK-Verbundprojekt "Antriebsstrang 2025". Laufzeit 01.09.2018 - 28.02.2022.BMWK/„Forschung für eine umweltschonende, zuverlässige und bezahlbare Energieversorgung“/03ET1531A-H/E
Benefits from using mixed precision computations in the ELPA-AEO and ESSEX-II eigensolver projects
We first briefly report on the status and recent achievements of the ELPA-AEO
(Eigenvalue Solvers for Petaflop Applications - Algorithmic Extensions and
Optimizations) and ESSEX II (Equipping Sparse Solvers for Exascale) projects.
In both collaboratory efforts, scientists from the application areas,
mathematicians, and computer scientists work together to develop and make
available efficient highly parallel methods for the solution of eigenvalue
problems. Then we focus on a topic addressed in both projects, the use of mixed
precision computations to enhance efficiency. We give a more detailed
description of our approaches for benefiting from either lower or higher
precision in three selected contexts and of the results thus obtained

Neuromarketing and consumer neuroscience:contributions to neurology
Background: 'Neuromarketing' is a term that has often been used in the media in recent years. These public discussions have generally centered around potential ethical aspects and the public fear of negative consequences for society in general, and consumers in particular. However, positive contributions to the scientific discourse from developing a biological model that tries to explain context-situated human behavior such as consumption have often been neglected. We argue for a differentiated terminology, naming commercial applications of neuroscientific methods 'neuromarketing' and scientific ones 'consumer neuroscience'. While marketing scholars have eagerly integrated neuroscientific evidence into their theoretical framework, neurology has only recently started to draw its attention to the results of consumer neuroscience.Discussion: In this paper we address key research topics of consumer neuroscience that we think are of interest for neurologists; namely the reward system, trust and ethical issues. We argue that there are overlapping research topics in neurology and consumer neuroscience where both sides can profit from collaboration. Further, neurologists joining the public discussion of ethical issues surrounding neuromarketing and consumer neuroscience could contribute standards and experience gained in clinical research.Summary: We identify the following areas where consumer neuroscience could contribute to the field of neurology:. First, studies using game paradigms could help to gain further insights into the underlying pathophysiology of pathological gambling in Parkinson's disease, frontotemporal dementia, epilepsy, and Huntington's disease.Second, we identify compulsive buying as a common interest in neurology and consumer neuroscience. Paradigms commonly used in consumer neuroscience could be applied to patients suffering from Parkinson's disease and frontotemporal dementia to advance knowledge of this important behavioral symptom.Third, trust research in the medical context lacks empirical behavioral and neuroscientific evidence. Neurologists entering this field of research could profit from the extensive knowledge of the biological foundation of trust that scientists in economically-orientated neurosciences have gained.Fourth, neurologists could contribute significantly to the ethical debate about invasive methods in neuromarketing and consumer neuroscience. Further, neurologists should investigate biological and behavioral reactions of neurological patients to marketing and advertising measures, as they could show special consumer vulnerability and be subject to target marketing
A Roadmap for HEP Software and Computing R&D for the 2020s
Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.Peer reviewe

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We
estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from
1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories.
Methods We used data from 3663 population-based studies with 222 million participants that measured height and
weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate
trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children
and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the
individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference)
and obesity (BMI >2 SD above the median).
Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in
11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed
changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and
140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of
underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and
countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior
probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse
was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of
thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a
posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%)
with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and
obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for
both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such
as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged
children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls
in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and
42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents,
the increases in double burden were driven by increases in obesity, and decreases in double burden by declining
underweight or thinness.
Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an
increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy
nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of
underweight while curbing and reversing the increase in obesit
