Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

open access: yesDrug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

The Digital Visibility‐Belonging Paradox: Digital Cohesion and Control in Contemporary Organizational Management

open access: yesHuman Resource Management, EarlyView.
ABSTRACT Digital visibility has become a central organizing condition in digitally mediated work, reshaping how employees are recognized, evaluated, and connected. In this conceptual paper, we theorize digital visibility as a sociomaterial HRM condition that simultaneously enables recognition and generates performative pressures. Anchored in relational

DINOSim: Training‐Free Semantic Segmentation on Microscopy Images

open access: yesMicroscopy Research and Technique, EarlyView.
DINOSim enables training‐free semantic segmentation of microscopy images from simple point prompts by leveraging DINOv2 embeddings, achieving performance comparable to supervised methods and robust generalization across diverse biological domains. ABSTRACT We present DINOSim, a training‐free method for segmenting objects in microscopy images without ...

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

DoseRAD2026: A benchmark dataset for AI-accelerated photon and proton dose calculation in radiotherapy. [PDF]

open access: yesMed Phys
Abstract Purpose Accurate dose calculation is a fundamental component of modern radiotherapy, enabling precise tumor irradiation while sparing surrounding healthy tissue. With the increasing adoption of magnetic resonance imaging (MRI)‐guided radiotherapy and growing interest in real‐time adaptive radiotherapy, there is a demand for fast and accurate ...

Soil health assessment using buried cotton underpants with the help of 1000 citizen scientists

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Soil is a vital resource for life on Earth. Although many soils are degraded, societal awareness of soil‐related issues is limited. To highlight soil as a key resource and fascinating study system, we initiated a citizen science project together with 1000 participants investigating soil health across Switzerland using buried cotton underpants.

Constructing Difference: Maternal Boundary‐Work in Science‐Based and Natural Mom Groups on Facebook

open access: yesSymbolic Interaction, EarlyView.
Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.
