From regulation to governance: The EU AI Act and HR governance along the employee lifecycle

Artificial intelligence (AI) is increasingly used in human resource management (HRM) to streamline processes, enhance decision-making and maintain competitiveness. At the same time, it raises critical concerns around transparency, discrimination, and employee autonomy, which are...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

An overview of international reference values for vitamin E intake – similarities and differences in derivation

Purpose The scientific knowledge for the essential fat-soluble vitamin E (VitE) remains inconclusive. There is still a lack of valid status parameters and deficiency symptoms for insufficient intake. Therefore, the derivation of a dietary reference value (DRV) for VitE is challen...

Cranial anatomy of the Middle Eocene Egyptian crocodylian Herugavialis cairensis provides new insights into gavialoid diversity in the Mediterranean region

Abstract Gavialoidea is presently composed of only two extant crocodylian species, the Indian gharial Gavialis gangeticus, and the false gharial Tomistoma schlegelii, both from southeast Asia. However, Gavialoidea displays a rich and near-cosmopolitan diversity in the fossil reco...

Ergot severity, ergot incidence and quality characteristics in German winter rye hybrid and population varieties

Ergot, caused by the fungus Claviceps purpurea , is a major disease in rye, leading to yield loss and contamination with ergot alkaloids that pose food safety risks. Against the background that the EU has significantly tightened the acceptable limits for ergot sclerotia since 1 J...

First report of ‘ Candidatus Arsenophonus phytopathogenicus’ in maize ( Zea mays L.) in Germany

In Germany, maize (Zea mays L.) is cultivated on approximately 2.4 Mha, making it one of the most widely grown arable crops alongside wheat and barley (German Federal Statistical Office, 2025). Although maize has previously been identified as a host of Candidatus Phytoplasma sola...

Evaluating the Impact of Explainable AI on Trust in AI-Assisted Code Review

The use of large language models (LLMs) for automated code review has brought significant change to a time-consuming part of software engineering. Prior work has shown that LLM-based code tools can improve code quality and enable more robust software development processes. As the...

Parents’ subjective understanding, use, reasons for non-use and perceived effectiveness of food labelling formats in Germany: a cross-sectional study of the Nutri-score, nutrition information panel and ingredients list

Abstract Background Food labels are intended to support healthier food choices, yet little is known about how parents engage with different labelling formats in Germany. This study examined parents’ subjective understanding and use of three food labelling formats in Germany, the...

Emergent properties of urban landscapes shape urban eco-evolutionary dynamics

Abstract Context Urbanization transforms natural ecosystems into heterogeneous and fragmented landscapes, creating novel selective pressures that can drive eco-evolutionary dynamics. However, the specific role of urban spatial structure in shaping these dynamics remains poorly un...

Dynamics of Kidney Calcium and Phosphorus Mineral Handling in Laying Hens During the Transition to Egg Production

ABSTRACT The transition from immature pullets to sexually mature female chickens is accompanied by pronounced structural and functional modifications. This is accompanied by coordinated changes in hormonal and metabolic pathways that primarily regulate reproduction, nutrient util...

Slow-moving pattern interfaces in general directions for a two-dimensional Swift–Hohenberg-type equation

Abstract We rigorously prove the bifurcation of slow-moving pattern interfaces with general direction in a two-dimensional Swift–Hohenberg-type model close to a Turing instability for a large class of nonlinearities. These interfaces describe the invasion of stripe and hexagonal...

The Local Least Action Criterion Fails as a Selection Criterion for Weak Solutions of the Compressible Euler Equations

Abstract It is now well known that the classical notion of admissible weak solutions (also known as weak entropy solutions) does not restore uniqueness for the multi-dimensional compressible Euler equations. Indeed, convex integration has shown that admissible weak solutions are...

Baseline gut microbiome and metabolome profiles predict weight loss after a structured lifestyle intervention

Abstract Background Obesity remains a global health challenge, and responses to lifestyle-based weight-loss interventions are heterogeneous. Here, we evaluate a one-year structured lifestyle program in 50 adults with obesity (mean BMI 42 ± 7.0 kg/m 2 ), integrating clinical, micr...

iCorn: A Methodological Framework for Multi-Label Disease Classification in Maize Using Uncurated Field Images

iCorn: Multi-Label Maize Disease Classification Framework Complete implementation of iCorn—a methodological framework for multi-label classification of maize leaf diseases from uncurated field images using deep learning, with production-ready mobile deployment. **Manuscript**: "i...

Anchors for Homology-Based Scaffolding

Homology-based scaffolding orders contigs based on conserved collinearity of homologous sequences across related species. Existing methods often rely on costly whole-genome alignments or show limited robustness when integrating multiple references. Here, we introduce an anchor-ba...

Effects of Extraction Methods on Inulin, Fructooligosaccharides and Microbial Inulinase Production from Stevia rebaudiana

In this study, Stevia fractions (root, leaf, stem and their mixture) were used for inulin extraction using aqueous extraction, enzyme-assisted extraction and enzyme-assisted decanter extraction. The extracts were used as carbon sources in submerged (SmF) fermentation, whereas the...

Predicting rainfed and irrigated yield responses under drought with soil-hydrological modelling and variety trials for economic evaluation

Abstract Agricultural droughts in many humid regions such as Southern Germany are projected to become more frequent and severe, leading to a substantial rise in irrigation demand to secure crop production. As a result, irrigation is becoming an increasingly important factor in ag...

An Adapted High-Pressure Homogenization Workflow Improves Recombinant β-Casein Recovery from Escherichia coli Inclusion Bodies

The efficient extraction and purification of recombinant β-casein from Escherichia coli is a crucial step in bioprocess engineering. This study evaluates an adapted high-pressure homogenization (HPH) workflow for recombinant β-casein recovery and compares it with osmotic shock (O...
