Abstract BACKGROUND Legumes are the primary source of plant protein in both human and livestock diets and, therefore, play an essential role in nutrition. Common vetch (Vicia sativa L.) is a grain legume widely used in animal feed. Its nutritional properties, particularly its high protein content, make it an adequate component to enrich feedstuffs ...

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
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
