On the structure of the sandpile identity element on Sierpiński gasket graphs

Abstract We consider the identity of the abelian sandpile group of finite approximation graphs of the Sierpiński gasket, and we show that the second-order term in the scaling limit converges to the path distance to the nearest corner on the Sierpiński gasket. The proof relies on...

Why they come (back): Motive clusters of seasonal employees and their multiple workplace commitments

This study develops seasonal employee typologies for the Alpine tourism and hospitality sector by connecting motives for seasonal work with varying levels of different workplace commitments and return intention. Conceptualizing the destination as an analytical lens rather than me...

Steering phosphorus reactivity with π-donor substituents

Substituent effects are a powerful handle to modulate the structure, reactivity, and function of phosphorus compounds. Strong π-donor substituents such as N-heterocyclic imines increase electron de...

Synthetic Strategies for Oxygenated Cyclohexanoid Frameworks

Highly oxygenated cyclohexanoid frameworks are key structural features in many natural products and remain challenging synthetic targets. Herein, we report investigations into two strategies for their preparation. A high-pressure Diels-Alder reaction enabled the construction of a...

Developing Key Sustainability Competencies in a Project-Problem-Based Approach to Sustainability Education: Learning Experiences of Pre-Service Primary Teachers

Education for Sustainable Development (ESD) aims to foster the key sustainability competencies (KSC) that enable future teachers to act as change agents. Yet little is known about how pre-service teachers interpret these competencies and their development within project- and prob...

Intermittent hypoxia interventions for inducing ventilatory acclimatization to high altitude?

Accumulation of ∼200 h of hypoxia exposure (pre-acclimatization) has been suggested to prevent the development of acute mountain sickness when a person is subsequently exposed to high altitude. These pre-exposures are typically undertaken intermittently at or near the place of re...

Teacher beliefs about climate action teaching: Exploring variation across instructional phases and types of action

Abstact Climate change education requires fostering students' skills in making informed decisions on climate-related actions. Thus, teacher education must equip teachers for such “climate action teaching” and may build on investigating teacher beliefs. Using the Theory of Planned...

Macrophage-specific LAMTOR2 deletion disrupts systemic iron homeostasis in mice

At the center of iron homeostasis, macrophages play a crucial role by phagocytosing senescent erythrocytes while nursing erythrocyte progenitors. A major route of cellular iron acquisition occurs via transferrin receptor 1 (TFR1)-mediated endocytosis of transferrin-bound iron, a...

Protocol for isolation and cryopreservation of human peripheral blood mononuclear cells for high-resolution respirometry

High-resolution respirometry (HRR) of peripheral blood mononuclear cells (PBMCs) relies on controlled preanalytical procedures. Here, we present an optimized workflow for PBMC isolation from human whole blood, followed by short-term cryopreservation at −80°C. The protocol include...

An international multicenter analysis of the outcome of pediatric first variceal hemorrhage

Background & Aims: Management of portal hypertension in children including primary prophylaxis of variceal bleeding is controversial due to limited understanding of mortality risk after first variceal hemorrhage (1VH). This international multicenter study was designed to advance...

Toward Secure Code Generation: Bridging Correctness and Security via Task-Adaptive Vulnerability Modeling and Execution-Based Benchmarking

Large language models (LLMs) are increasingly used for program synthesis, yet they often generate code that is functionally plausible but insecure. Progress in secure code generation has been hindered by benchmarks that are small, non-executable, leak mitigation details, or rely...

Attributes, abstractions, and combinations: a new taxonomy for studying how parties invoke social groups

Research increasingly examines which social groups political actors refer to. Yet, existing approaches typically inherit classifications shaped by demand-side perspectives or conflate how groups are defined with how they are framed. We propose a novel, attribute-centered taxonomy...

Relieving the Burden on Caregivers: A Single-Group, 4-Week Pilot Study Evaluating the Impact of a Brief Online Psychoeducation Program (AES) on Burden Reduction and Schizophrenia-Related Knowledge for Informal Caregivers of Individuals with Schizophrenia in German-Speaking Countries

PURPOSE: Informal caregivers of people with schizophrenia often face substantial psychological burden and limited support. Although psychoeducational family interventions are effective and are recommended by international guidelines, their clinical use is limited by systemic and...

Tree-ring-anchored analog reconstruction of daily climate distributions from instrumental data with Bayesian distributional regression: Application to the European Alps

Daily to seasonal weather information remains rare in Quaternary science, because proxy archives typically resolve only seasonal or annual means. Yet climate is felt at daily timescales, through frost, snowfall, wind and precipitation. Here a framework of Bayesian Additive Models...

Optimal eigenvalues on a metric graph with densities

Abstract We introduce and study Laplacians on a finite metric graph endowed with generalized densities, that is, measures of finite mass. One important motivation is that this setting provides a common framework for several interesting classes of operators: discrete graph Laplaci...

Infrared spectroscopy of coronene+ and C60+ resolving 13C isotopologues

Infrared signatures of carbonaceous molecules in space vary among different lines of sight and astronomical objects, providing information on the local ratio of 13C-12C. The interpretation of these observations relies on high-resolution laboratory spectra capable of resolving iso...

Beyond rare gases: Cooling of trapped BN− ions by H2 molecules

Quantum dynamics of collisional cooling of the BN- anion in a cold trap is carried out by using the ortho- and para-H2 molecules as a buffer gas. The calculations are performed using the full four-dimensional interaction potential energy surface in which both BN- and H2 are treat...

Impact of Cost Transparency and Mixed Revenue Use on the Maximum Acceptable Carbon Tax

Abstract Public acceptability remains a major barrier to implementing effective carbon taxes. Resistance often stems from misconceptions about the costs and benefits of the policy. Two potential tools to improve acceptability are revenue recycling, which links the tax to tangible...

The German S3-level guideline for the diagnosis and management of rare dental disorders

Abstract Objectives The aim of this German S3-level guideline project was to develop evidence-based recommendations to support professionals in the diagnosis and management of individuals with rare dental disorders. The research question was which form of dental care should be pa...

Topology-Controlled Photophysics of Ionized C14H10 Isomers

Abstract The optical signatures of polycyclic aromatic hydrocarbons (PAHs) are highly sensitive to their molecular geometry, charge state, and intermolecular interactions. A comparison between the linear anthracene and angular phenanthrene ions highlights how topological effects...
