Water, carbon, and light use efficiencies in an old hemiboreal coniferous forest: nine-year patterns under hydroclimatic variability

Abstract. Hemiboreal forests bridge boreal and temperate biomes by combining functional and compositional features of both and playing a key role in regional carbon and water cycling. Water (WUE), carbon (CUE), and light (LUE) use efficiencies provide integrative indicators of ho...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

MSP4BIO Deliverable 3.4: Ecological toolkit (ESE1) for MPAs prioritization and networking

The Ecological Toolkit (ESE1) was developed to support the design, establishment and management of Marine Protected Areas (MPAs) by improving decision-making processes, focusing on prioritisation of areas, integration of connectivity processes and assessment of human impacts on m...

Arousal does not enhance the dominant spatial scope of attention

A fundamental aspect of attention is its spatial scope: whether attention is narrowly focused or more broadly distributed across the visual field. Here, we examined whether the spatial scope of attention is modulated by tonic arousal level. Based on findings that arousal amplifie...

Grid4Earth: An Open-Source Python Ecosystem for Geospatial Data Integration Using an Ellipsoidal HEALPix DGGS

Abstract. The rapid growth in Earth observation (EO) and Digital Twin Earth data volumes creates a need for global, reproducible, and cloudnative spatial representations. Conventional latitude–longitude grids and projected tiling systems remain useful, but they introduce projecti...

Syrona: an open-source visual analytics tool for pairwise comparison of health datasets in OMOP CDM

Abstract Background Health research increasingly relies on observational datasets that capture systematically different patient populations, affecting the representativeness, comparability, and transportability of study findings. Yet these differences are rarely quantified across...

CT-based radiological score (AMESI CT-score) for severity of bowel injury in acute mesenteric ischemia

PURPOSE: To evaluate whether common bowel-related CT signs alone can reliably identify irreversible bowel injury in acute mesenteric ischemia (AMI) and to develop a radiological score to enhance reporting and assist clinical decision-making. METHODS: This ancillary analysis of th...

Bias in Genome-Wide Association Test Statistics Due to Omitted Interactions

Abstract Over the past two decades, genome-wide association studies (GWAS) enabled the discovery of thousands of variants associated with many complex human traits. However, conventional GWAS are still widely performed with linear models with the assumption that the genetic effec...

Imagery Interventions and Cognitive‐Behavioural Therapy for Psychological Complaints Related to Bullying: A Systematic Review and Meta‐Analysis

ABSTRACT Bullying is associated with internalizing symptoms and impaired everyday functioning. Cognitive‐behavioural therapy (CBT) and imagery interventions have been studied as treatments to improve mental health after such experiences. This meta‐analysis aimed to evaluate the e...

Delivery mode and maternal health conditions before and after childbirth: A population‐based cohort study from Estonia

INTRODUCTION: Cesarean section (CS) is the most common gynecological surgery globally, with rates increasing in many developed countries. In Estonia, the CS rate rose from 6.4% in 1992 to 20.6% in 2021. While CS can be lifesaving when medically necessary, its rising use without c...

Marine protected areas and maritime spatial planning integration dynamics across Europe

Maritime Spatial Planning (MSP) has emerged as a central governance tool to balance ecological, social, and economic uses of marine space, while Marine Protected Areas (MPAs) remain essential for biodiversity conservation and ecosystem resilience. Effective integration of MPAs in...

Doors and Windows in László Krasznahorkai’s First Two Novels

Abstract This study examines the motif of doors—and, to a lesser extent, windows—in László Krasznahorkai’s novels Satantango and The Melancholy of Resistance, situating them within the broader framework of media theory and relational philosophy. Doors, understood as physical thre...

The clinical and molecular spectrum of AGO2-associated Lessel-Kreienkamp neurodevelopmental syndrome

Abstract Background Pathogenic variants in AGO2 ,encoding a central component of the RNA-induced silencing complex (RISC), cause the neurodevelopmental disorder Lessel-Kreienkamp syndrome (LESKRES). The variant spectrum and associated molecular mechanisms underlying phenotypic va...

Fitness effects of local seasonal adaptation depend on the timing of reproduction in a range-expanding butterfly

Abstract Local seasonal adaptation across latitudes is ubiquitous, but its fitness consequences are rarely estimated in the field. Using a common-garden field experiment at the northern range margin of the butterfly Lasiommata megera, we show that fitness consequences of among-po...

Contrasting population genetic structures of freshwater eels ( Anguilla marmorata, A. bicolor, A. mossambica ) from Madagascar

Abstract Freshwater eels (genus Anguilla ) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integri...

Misquoted No More: Securely Extracting F* Programs with IO

Shallow embeddings that use monads to represent effects are popular in proof-oriented languages because they are convenient for formal verification. Once shallowly embedded programs are verified, they are often extracted to mainstream languages like OCaml or C and linked into lar...

This appendix provides the supplementary materials accompanying the paper “Data Cooperatives Starter Kit: A Governance Artifact with Fuzzy-Logic Stewardship Evaluation.”

Effect of Electrolyte,Applied Voltage, and DNA Concentrationon the Translocation Dynamics of a Single-Stranded DNA through a Solid-StateNanopore

Abstract Solid-state nanopores enable label-free detection of biomolecules by monitoring ionic current modulations during molecular translocation. However, reliable measurements are often limited by rapid, poorly controlled translocation dynamics producing short, low-resolution s...

From Noise to Knowledge: Distill Social Media Opinions on Rumor Detection Exploiting LLMs

The majority of social media research relies on datasets gathered from social media websites such as Reddit and Twitter. However, their intrinsic high noisy content reduces the performance of data-driven models. This restriction of noisy data has made data preparation techniques...
