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 ...

Presence of keel bone damage in laying hens, pullets and roosters of local chicken breeds
(2024-01-26)
In commercial laying hens, keel bone damage (KBD) is a severe health and welfare problem leading to pain, reduced mobility and decreased laying performance. Flocks of all production systems and hybrid lines can be affected. KBD is a multifactorial welfare issue and, among other factors, associated with a high laying performance which negatively affects the calcium deposit in the medullary bones. Therefore, mature hens of local breeds with much lower egg production than commercial hybrids may be expected to show less ...

Controlled Ring Opening of a Tetracyclic Tetraphosphane with Twofold Metallocene Bridging
(2024-02-19)
A direct route to a doubly ferrocene bridged tetracyclic tetraphosphane 1 was developed via reductive coupling of Fe(CpPCl₂)₂ (2 a), where a chlorine terminated linear P₄-compound 3 could be identified as an intermediate. Selective P−P bond activation was further achieved by reacting 1 with elemental selenium or [Cp*Al]₄, where regioselective insertion of Se or Al atoms resulted in ferrocenylene bridged [P₄Se] (4) or [P₄Al] (7) moieties. Compound 7 can be transformed to a hydrogen terminated linear P₄ species, 8, ...

Does intense tax competition boost public acceptance for inter-municipal cooperation? Evidence from a survey among German citizens and local politicians
(2024-03-28)
Intense tax competition among local governments limits their potential for tax revenues. Inter-municipal cooperation (IMC) in general and joint business parks in particular constitute a platform to coordinate local tax rates with neighboring municipalities to reduce tax competition. We ask whether local politicians and citizens are aware of this logic and whether they account for it. Using survey data from German municipalities, we find citizens’ support for joint business parks to increase in the intensity of tax ...
