Self-regulatory strategy use in exam preparation: reflection and automaticity shape successful self-regulation

In a preregistered reanalysis of two longitudinal studies (N = 200, N = 294), we examined students’ self-regulation during exam preparation. Assessments included a baseline, twice-weekly measures over two weeks, a fourth-week questionnaire, and (in Study 2) a follow-up on exam gr...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...

Surface Segregation in Compositionally Complex Ag‐Au‐Pd‐Pt Solid Solutions: Insights From High‐Throughput Experimentation and Atomistic Simulations

ABSTRACT The activity of compositionally complex electrocatalysts depends on their surface composition, which can be different from the volume composition. In solid solutions, surface segregation under vacuum can be estimated based on the surface energy of the constituent element...

The pseudoautomorphism group of P3 blown‐up at 8 very general points

Abstract We prove that the pseudoautomorphism group of a blow‐up of at 8 very general points is trivial. We also establish the injectivity of the Coble representation associated to blow‐ups of at general points, answering a question of Dolgachev–Ortland.

On the Role of Al on the Microstructure Formation in Ti-rich Refractory Compositionally Complex Alloys

We gratefully acknowledge financial support by the Deutsche Forschungsgemeinschaft (DFG) with in the project 524725651 (KA 4631/6-1, HE 1872/45-1, and GO 2283/8-1). We acknowledge the chemical analysis by HCGE at the Institute for Applied Materials (IAM-AWP) by Dr. Bergfeldt, Kar...

Timing of PCI in Patients Undergoing Transcatheter Aortic-Valve Implantation

BackgroundApproximately one half of patients undergoing transcatheter aortic-valve implantation (TAVI) have concomitant coronary artery disease. Although percutaneous coronary intervention (PCI) is often performed before TAVI, the preferred treatment strategy has not been establi...

Orchestration Up Close: Sustainable Business Model Innovation Through the Experiences and Activity Patterns of Secondary Stakeholders

ABSTRACT While much research stresses the importance of stakeholder involvement and inter‐organizational collaboration in sustainable business model innovation, less is known about the dynamics and actor roles of these collaborative processes. This article investigates one partic...

Nanosecond Pulsed Microwave Plasma Torch for Continuous In‐Line H 2 O 2 Supply: A Path to Stable and Scalable Plasma‐Driven Biocatalysis

ABSTRACT Plasma‐driven H 2 O 2 generation offers a potential sustainable route for biotransformations, but its application is hindered by challenges such as insufficient H 2 O 2 production and enzyme degradation. This study establishes plasma‐driven biocatalysis using a nanosecon...

Process evaluation of the randomized trial—“Care management for older people with cognitive impairment during and after hospitalisation in Germany (intersec-CM)”

Abstract Background Effective care of people with cognitive impairment and their families depends, among other things, on the cooperation of the professionals involved in their care. An effective dementia care management support model for people with dementia and their families f...

Hepatitis-associated virus infections in Austrian equids: A survey of equids sampled across Austria

This study aimed to determine the (sero)prevalence of equine hepacivirus (EqHV), equine parvovirus-hepatitis (EqPV-H), equid hepatitis B virus (EqHBV) and hepatitis E virus (HEV), in equids across Austria and to identify associated risk factors. In a cross-sectional study conduct...

Deep learning-based structural element extraction and knowledge-graph-based validation of 2D bridge drawings

The maintenance and management of existing bridge infrastructure rely on conventional two-dimensional construction drawings, which remain largely unstructured and difficult to integrate into digital workflows, including Building Information Modeling (BIM). In prestressed concrete...

When trauma turns septic: Associated factors and focus-specific mortality in 61,399 patients from the TraumaRegister DGU®

PURPOSE: Sepsis is a critical complication after severe trauma. This study aimed to identify factors associated with sepsis, to characterise sepsis foci in relation to injury pattern, and to evaluate the association of sepsis with multiple organ failure (MOF) and in-hospital mort...

The Curious Life of Walter Lode

ABSTRACT This paper is intended to serve as a supplement to the work [ PAMM ‐ Proceedings in Applied Mathematics and Mechanics 24, no. 2 (2024): e202400004] to underline the significance of the Lode angle and Lode parameter—concepts attributed to Walter Lode—for the development o...

One (Noisy) Bit to Rule Them All: Key Recovery from Randomness Leakage in ML-DSA

Abstract The Fiat-Shamir transform is one of the most widely applied methods for secure signature construction. Fiat-Shamir starts with an interactive zero-knowledge identification protocol and transforms this via a hash function into a non-interactive signature. The protocol’s z...

Measures for intersectional mental healthcare: results from a participatory interview and focus group study with psychosocial counsellors, people with experience of using mental health services and providers

BACKGROUND: Discriminatory practices and barriers to care are increasingly recognised as a significant challenge for mental healthcare institutions. Yet, little research has considered what measures people with experience of using mental health services and mental healthcare serv...

Single fuel particle emissivity evolution of biomass, coal and coal char

In solid fuel combustion systems, reacting particles form the hottest surfaces and, therefore, contribute significantly to the radiative heat balance within these environments. Recently, experimental investigations of single-particle emissivity report values for coal and various...

Progressive Melt Fractionation as the Primary Control on the Formation of Rare-Metal Pegmatites: Evidence for Continuous Granite–Pegmatite Evolution in the Central Kalba Ore District, Eastern Kazakhstan

Rare-metal pegmatites of the Kalba–Narym belt (Eastern Kazakhstan) represent an important source of Li, Cs, Ta, Nb, Be, and associated critical metals. Despite extensive geological investigations, the relationships between granites, pegmatites, and late-stage alteration products...

Suicide prevention through a SafetyPlan intervention for patients after a suicide attempt or in a suicidal crisis (SAFETY+): a study protocol of a randomised-controlled trial in acute inpatient psychiatric care

Individuals undergoing acute inpatient psychiatric treatment or who have recently been discharged face an especially elevated risk of suicide. Nevertheless, suicide-specific interventions are still not routinely implemented in inpatient psychiatric care in Germany. Safety plan in...

Direct atomistic simulation of dislocation climb in fcc Ni

Dislocation climb is one of the key processes controlling the mechanical response and microstructure evolution of materials at high temperatures. The mechanisms of this phenomenon are still unclear due to its complex nature, which involves interactions between point defects and d...
