Task-Level Checkpointing and Localized Recovery to Tolerate Permanent Node Failures for Nested Fork–Join Programs in Clusters
(2024-03-13)
Exascale supercomputers consist of millions of processing units, and this number is still growing. Therefore, hardware failures, such as permanent node failures, become increasingly frequent. They can be tolerated with system-level Checkpoint/Restart, which saves the whole application state transparently and, if needed, restarts the application from the saved state; or with application-level checkpointing, which saves only relevant data via explicit calls in the program. The former approach requires no additional ...

Examining the glottal stop as a mark of gender-inclusive language German
(2024-02-02)
Grammatical gender form influences readers’ mental gender representations. Previous research demonstrates that the generic masculine form leads to male-biased representations, while some alternative forms lead to female-biased representations. The present research examines the recently introduced glottal stop form in spoken language in German, where a glottal stop (similar to a short pause), meant to represent all gender identities, is inserted before the gender-specific ending. In two experiments (total N = 1188), ...

Maintain your mind, mantain your focus: Effects of focused attention and intensity in experienced runners
(2024-02-26)
The intensity that people choose for their endurance activities has a major influence on their affective experience. Furthermore, the direction of attention (e.g., internal or external) during endurance activities may significantly influence performance and ersonal perceptions. Therefore, in the current study, we focus on the interaction between intensity and attentional focus. We aim to address the question of whether adopting an internal (IAF; breathing) or an external attentional focus (EAF; environment), compared ...

Coherent acoustic phonons in a coupled hexagonal boron nitride-graphite heterostructure
(2024-02-14)
Femtosecond optically excited coherent acoustic phonon modes (CAPs) are investigated in a free-standing van der Waals heterostructure composed of a 20-nm transparent hexagonal boron nitride (hBN) and a 42-nm opaque graphite layer. Employing ultrafast electron diffraction, which allows for the independent evaluation of strain dynamics in the constituent material layers, three different CAP modes are identified within the bilayer stack after the optical excitation of the graphite layer. An analytical model is used to ...

Bedingungslose ambulante Erziehungshilfen
(2024-02-12)
„Bedingungslose Jugendhilfe“ ist die Bezeichnung für ein offenes politisches Reform- und sozialpädagogisches Forschungsprogramm, das sich gegen die Stigmatisierung von Nutzer_innen erzieherischer Hilfen stellt. In dem Programm wird der Frage nachgegangen, ob es erstrebenswert und praktisch umsetzbar wäre, wenn die Hilfen zur Erziehung unabhängig vom Vorliegen eines erzieherischen Bedarfs als universale Unterstützungsleistungen für alle Kinder, Jugendlichen und ihre Eltern attraktiv und zugänglich wären. Im vorliegenden ...

Bedingungslose Kinder- und Jugendhilfe
(2024-02-28)
Die Kinder- und Jugendhilfe gilt als öffentliche Infrastruktur der Erziehung und Bildung. Einer Inanspruchnahme von Hilfen zur Erziehung im Rahmen der KJH geht die Feststellung eines erzieherischen Bedarfs voraus. Demnach steht häufig eine Defizitdiagnose elterlicher Erziehung und Bildung am Beginn einer Hilfe, mit nicht selten stigmatisierender Wirkung. Der vorliegende Schwerpunkt beschäftigt sich mit den Perspektiven einer „Bedingungslosen Kinder- und Jugendhilfe“, womit nach den Möglichkeiten einer breiten und ...

Bond strength, failure criteria and calculation methods for adhesively bonded timber–concrete composites
(2024-04)
The bond strength of adhesively bonded timber–concrete composites (ATCC) with prefabricated concrete elements is usually described using the shear strength of the timber. This approach, however, often fails to consider the actual failure modes of the bondline and also the interaction between shear stresses and stresses perpendicular to the bondline has not yet been comprehensively understood. To address this limitation, a reliable calculation method is required, where stress determination, failure criterion, and ...

Why has animal science not led to improved farm animal health and welfare?
(2024-01-05)
To sustain the economic viability of a livestock farm in a global market, characterised by a price undercutting competition, farmers are forced to adapt to what the market demands. At the same time, they have to care for the functionality of the farm system as a whole and of the subsystems, such as the farm animals, so that they for their part they can contribute to an economic success. Now, that animal health and welfare (AHW) has become an increasingly important issue for citizens and consumers, not only the decision ...

Contribution of membrane-associated oscillators to biological timing at different timescales
(2024-01-09)
Environmental rhythms such as the daily light-dark cycle selected for endogenous clocks. These clocks predict regular environmental changes and provide the basis for well-timed adaptive homeostasis in physiology and behavior of organisms. Endogenous clocks are oscillators that are based on positive feedforward and negative feedback loops. They generate stable rhythms even under constant conditions. Since even weak interactions between oscillators allow for autonomous synchronization, coupling/synchronization of ...

Quantitative analysis of the effect of foam morphology on the quasi-static and cyclic-dynamic tensile properties
(2024-02-28)
This study is the initial investigation into the relationship between the structure of foam and its quasi-static tensile and tension-tension fatigue properties. It is also the first examination of crack initiation and propagation in relation to various foam morphology patterns. The overall foam morphology and geometric appearance of the cell structure can be altered by varying the parameters of foam injection molding. Quantitative features of foam morphology are measured in terms of cell diameter, cell distance, cell ...
