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...

Visualising Physcomitrium patens protoplasts with full‐rotation soft X‐ray tomography

Abstract Soft X‐ray tomography (SXT) is a label‐free, high‐resolution imaging modality that is optimal for 3D visualisation of whole hydrated cells. Although SXT has been extensively used to study remodelling in more than 130 mammalian cell lines, its application to plants remain...

Beyond carbon dioxide: decoupling headspace and buffering reveals a bicarbonate requirement for anaerobic gut fungi growth

Abstract Background Anaerobic gut fungi ( Neocallimastigomycota ) are major lignocellulose degraders in herbivore gastrointestinal tracts, but reproducible axenic cultivation remains difficult because conventional serum-bottle systems intrinsically couple CO 2 headspace, bicarbon...

The microstructure and some properties of the novel biomedical ZrTiFe alloy subjected to high-pressure torsion deformation

Abstract Zr- and Ti-based alloys, due to their excellent mechanical, physical, and biological properties, are increasingly used as biomaterials. Although these alloys have been used in medical applications for over 60 years, several issues remain associated with their use in this...

A Stable Formulation for Wave‐Induced Fracture in Peridynamics

ABSTRACT The bond‐associated quadrature point formulation is a very accurate peridynamic formulation for elasticity, but modeling fracture by the traditional deletion of bonds can trigger severe numerical instabilities. These instabilities are most pronounced for wave‐induced fra...

RAPNet: Efficient Near-Sensor Radar Data Pre-Processing via DFT-to-GEMM Mapping

Radar is ubiquitous in many domains such as automotive. Modern radar sensors generate large amounts of data that needs to be moved from sensor nodes to Processing Units (PUs). In general, data movement incurs high power consumption and latency. To reduce data movement, processing...

Kinetic Programming of Dynamic Covalent Networks via Isomer-Pure Diels–Alder Kinetics

Abstract The precise control of material properties through molecular-level architecture remains an enormous challenge in materials science. Here, we present a platform for the kinetic programming of covalently cross-linked networks by translating selective cycloreversion kinetic...

Antimicrobial Composite Nanofiber Membranes Containing Cross-Linked β-Cyclodextrin Encapsulated Essential Oils

Abstract Membrane biofouling leads to low permeate quality and increased operational costs due to the need for frequent physical and chemical cleaning. Incorporation of antimicrobial agents such as essential oils (EOs) into polymeric membranes presents a promising solution to mit...

Molecular Control of Neural Stem Cell Quiescence in the Adult Zebrafish Telencephalon: Established Mechanisms and an Integrative Hypothesis

The zebrafish telencephalon is an excellent model for adult neurogenesis under physiological and regenerative conditions, as many pathways regulating neural stem cell behavior are conserved with mammalian neurogenic niches. Resident radial glial cells (RGCs) serve as neural stem...

Support as a Service: Building the bwFDM-Helpdesk for and with the RDM community in Baden-Württemberg

The state initiative for research data management (RDM) in Baden-Württemberg bwFDM [1] is advancing RDM support on the state level by implementing a new helpdesk system that will provide faster, more efficient support for researchers and staff at research institutions in Baden-Wü...

Sustainable pectin/rosemary oil-loaded solid lipid nanoparticles film for packaging applications: Shelf-life insights for ready-to-eat chicken breast

This study proposes a novel hybrid hydrocolloid film using pectin and rosemary oil-loaded solid lipid nanoparticles (RO-SLN), integrating a biodegradable matrix with nanoencapsulated bioactive compounds to create a sustainable and effective active packaging system for extending t...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

Substrate insulated Josephson junctions for superconducting quantum circuits

We have developed a fabrication technique for Josephson junctions that employs a three-dimensional patterned, low-loss substrate instead of commonly used organic resists. The technique enables the fabrication of high-quality trilayer junctions from a wide range of geometries and...

A goodness-of-fit test for the zeta distribution with unknown parameter

Abstract We introduce a new goodness-of-fit test for count data on $$\mathbb {N}$$ N for the Zeta distribution with unknown parameter. The test is built on a Stein-type characterization that uses, as Stein operator, the infinitesimal generator of a birth–death process whose stati...

Self-reinforcing barriers to municipal digital government: A system dynamics perspective

Municipal governments have invested substantially in digital government endeavors, yet progress in public sector digital transformation remains surprisingly slow. Although research has repeatedly identified, categorized and reclassified barriers while also proposing numerous stra...
