Signatures of Positive Selection and Climate Associations in Human OXPHOS Genes

Human adaptation to diverse climates has played a major role in shaping human evolution. Mitochondrial oxidative phosphorylation (OXPHOS) is central to energy production and thermogenesis; however, the respective contributions of the mitochondrial and nuclear genomes to climate a...

Global Existence of Weak Solutions to a Two-Phase Diffuse Interface Model of Ferrofluids Dynamics

Abstract. Ferrofluids are a class of materials that exhibit both fluid and magnetic properties. We consider a two-phase diffuse interface model for the dynamics of ferrofluids on a bounded domain. One phase is assumed to be magnetic, the other phase can be magnetic or nonmagnetic...

Contesting reputational advantages: Issue ownership and negative campaigning

Research on issue-based negative campaigning typically emphasizes issue salience and parties’ own issue strengths. This paper shifts the focus to the targets of attacks. We argue that negative campaigning on policy issues is systematically structured by the competence of the oppo...

Development and Application of Computational Chemistry Methods

Computational chemistry has become an essential bridge between microscopic theory and measurable chemical behaviour [...]

Decrease of magnetocaloric effect and magnetic susceptibility of ferromagnet due to magnetostructural phase transition

Abstract In the present article the impact of the first-order magnetostructural phase transition (MSPT) on the spin-exchange energy density has been considered to estimate the influence of MSPT on the magnetic susceptibility of ferromagnetic solid and magnetocaloric effect (MCE)....

A pseudohelicase-centered complex couples assembly-dependent RNA cleavage to poly(UG)ylation

Robust RNA interference in Caenorhabditis elegans requires Argonaute targeted RNAs to be cleaved by RDE 8 and poly(UG)ylated by MUT 2, generating templates for RNA dependent RNA polymerases that synthesize secondary small RNAs. RDE 8 and MUT 2 are physically coupled within the cl...

A De Giorgi conjecture on the regularity of minimizers of Cartesian area in 1D

Abstract We prove a $$C^{1,1}$$ C 1 , 1 -regularity result for minimizers of the functional $$ \int _I \sqrt{1+|Du|^2} + \int _I |u-g|ds,\quad u\in BV(I), $$ ∫ I 1 + | D u | 2 + ∫ I | u - g | d s , u ∈ B V ( I ) , provided $$I\subset \mathbb {R}$$ I ⊂ R is a bounded open interval...

Genomic insights into the evolutionary dynamics of Phytophthora infestans lineages after the Irish Potato Famine

Abstract Background Genomic analysis of infected herbarium specimens provides the opportunity to investigate the evolutionary history of plant pathogens, leading to discoveries such as the identification of FAM-1/HERB-1 as the Phytophthora infestans lineage that caused the ninete...

Interpretation in the Age of AI: (Re)Negotiating the Legal Language Zone in Professional Correspondence

Abstract This conceptual paper introduces the Legal Language Zone (LLZ) as a framework for analysing professional legal correspondence in the age of artificial intelligence. Drawing on the Businesslike Zone from business communication pedagogy, the LLZ is theorised as a multidime...

Lessons from integrated climate change adaptation and mitigation interventions for synergies and co-benefits in African cities

The diverse impacts of climate change on urban areas and the strategies to adapt have been widely studied over the past 25 years. While there is consensus on the importance of adaptation and mitigation, significant uncertainties stem from data paucity for certain regions, especia...

Being journalists on social media: Contrasting professionals’ self-perceptions to role expectations among adolescents

On social media, efforts by individual journalists to share news with audiences may be a viable response to personality-driven news presentation coming from peripheral actors like influencers, who are increasingly popular information sources for adolescents. Yet, when using socia...

Hypoellipticity of analytic differential operators in general ultradifferentiable classes

Abstract We show that analytic pseudodifferential and Fourier integral operators behave well for ultradifferentiable classes satisfying minimal regularity properties. As an application we investigate the ultradifferentiable regularity properties of several examples of analytic di...

Reconstitution of multistep recruitment of ULK1 to membranes in autophagy

Abstract The Human ULK1 autophagy-initiating complex consists of ULK1, FIP200, and the HORMA domain heterodimer ATG13:ATG101. PI3P is essential to recruit ULK1C to membranes for ULK1, but ULK1C subunits do not contain PI3P-binding domains. Here we show that the ATG13:ATG101 dimer...

Bridging perturbation theory and simulations: Initial conditions and fast integrators for cosmological simulations

These lecture notes provide an introduction to the generation of initial conditions for cosmological N N -body simulations. Starting from the definition and properties of Gaussian random fields, we discuss their role in cosmology and the efficient generation of such fields using...

The sine-Gordon equation in light-cone coordinates on the half-lines revisited: a Riemann–Hilbert approach

Abstract In this work, we study the initial-boundary value (IBV) problems for the sine-Gordon (sG) equation in the light-cone coordinates $$u_{xt}=\sin u$$ u xt = sin u in the quarter-planes $$x> 0, t > 0$$ x > 0 , t > 0 and $$x < 0, t > 0$$ x < 0 , t > 0 , assuming a suitable de...

A NECESSARY AND SUFFICIENT CONDITION FOR SIZE CONTROLLABILITY OF HETEROSKEDASTICITY ROBUST TEST STATISTICS

We revisit size controllability results in Pötscher and Preinerstorfer (2025, Econometric Theory 41, 249–301) concerning heteroskedasticity robust test statistics in regression models. For the special, but important, case of testing a single restriction (e.g., a zero restriction...

GRACE-OFF: A Machine-Learned Interatomic Potential for Organic Liquids Using the GRACE Architecture

Abstract Machine-learned interatomic potentials (MLIPs) have become an increasingly important tool for molecular dynamics (MD) simulations, enabling near quantum-mechanical accuracy at significantly reduced computational cost. Recent studies indicate that the Graph Atomic Cluster...

Double Adaptation: Negotiating Closeness and Managing Boundaries in Journalist–Politician Relations

Closeness with politicians is both a professional resource and a potential risk for journalists, as it enables access to information but may compromise autonomy and integrity, particularly within today’s hybrid media environment. This study proposes the conceptual framework of do...

Categorizing race profiles in professional men’s and women’s road cycling races using clustering

Abstract Background Professional road cycling races differ in physiological demands because race profiles vary. Yet no standardized method exists to categorize race profiles across professional road cycling races. Organizer labels are inconsistent or missing. Systematic categoriz...

Who is heard in wolf debates? Gender, emotion, and conservation legitimacy

Wolves evoke intense public debate shaped by cultural norms and power relations. However, the role of gender in influencing discourse, credibility, and participation in these conflicts remains underexplored. This study examines how gender structures emotional expression, epistemi...
