Modeling saffron corm production under climate change using Hydrus‐1D enhanced with a novel crop yield module

open access: yesVadose Zone Journal, Volume 24, Issue 6, November/December 2025.
Abstract Saffron (Crocus sativus L.) is an ideal crop for arid and semiarid regions due to its low water requirement and high economic value. This study involves calibration and validation of the Hydrus‐1D model in order to explore the influence of climate change on saffron corm production.

A Quantitative Analysis of 21st Century Skills: A Case of Semantic and Psychometric Overlap

open access: yesInternational Journal of Selection and Assessment, Volume 33, Issue 4, November 2025.
ABSTRACT While the concept of 21st century skills has become omnipresent, there is little consistency regarding the terms, definitions, or measurement instruments used, causing a problem for personnel selection policies as well as education and training.

Transverse spin Hall effect and polarization twist ribbon at the sharp focus

open access: yesКомпьютерная оптика
In this work, using the Richards-Wolf formalism, we found explicit analytical expressions for the coordinates of the major and minor axes of the polarization ellipse centered in the focal plane for a cylindrical vector beam of integer order n. For such a

Effects of liming on soil physical and chemical properties in Europe and North America: A review

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Soil acidity is one of the major constraints limiting crop production worldwide. About 50% of the global arable land is acidic. Liming remains an effective strategy for soil acidity amelioration and improvement of soil fertility. The objective of this review was to summarize information on liming effects on soil physical and chemical ...

Spin-orbital conversion of the light field immediately behind an ideal spherical lens

open access: yesКомпьютерная оптика
The Richards-Wolf equations not only adequately describe a light field distribution at the sharp focus, but are also able to describe a light field distribution just behind an ideal spherical lens, i.e. on a converging spherical wavefront.

Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust under‐thrusting its Asian counterpart and Asian crustal thickening. However, a single crustal layer of up to

Stable isotope analysis reveals individual variations in feeding habits among wild Japanese macaques

open access: yesEcological Research, Volume 40, Issue 4, Page 523-538, July 2025.
In this study, we conducted a dietary analysis using stable isotopes on the Japanese macaque (Macaca fuscata) group on Koshima Island, Japan. As a result, we clarified the variation in isotope ratios at the individual level, and indicated that this variation is affected by attributes such as sex or dominance‐subordinate relationships in this group ...

Seedling emergence of guar (Cyamopsis tetragonoloba L.) genotypes and their growth under irrigation water salinity

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Salinity and water scarcity are threatening the sustainability of agriculture in the arid regions of the world. There is an urgent need to develop information on suitable crops that can tolerate salinity and drought to ensure the long‐term viability of agriculture in these regions.
