Limnology and Oceanography: Methods, EarlyView.Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
Laser &Photonics Reviews, EarlyView.This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

An Analysis of Blue Straggler Stars in Open Clusters
Research Notes of the AASAbstract The presence of blue straggler stars (BSSs) in open clusters (OCs) presents an opportunity to study star formation and cluster dynamics. Our paper analyzes several properties of BSSs across 161 OCs of different ages, metallicities, and sizes.

Panchromatic study of star clusters: binaries, blue lurkers, blue stragglers and membership
, 2022 Binary systems can evolve into immensely different exotic systems such as blue straggle stars (BSSs), yellow straggler stars, cataclysmic variables, type Ia supernovae depending on their initial mass, the orbital parameters and evolution. The aim of this thesis is to understand the demographics of post-mass-transfer systems (BSSs, white dwarfs and blue

Oikos, EarlyView.Rapid climate change in the Arctic is altering biological communities and their subsequent effects on ecosystem functioning. For example, warming‐induced shrub expansion accelerates biogeochemical cycles in part by increasing high‐quality litter inputs.

People and Nature, EarlyView.Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...
