A Mathematical Model for Calculating the “Brittleness‐Ductility” Drop Coefficient of Sandstone in Mining Zones

open access: yesDiscrete Dynamics in Nature and Society, Volume 2020, Issue 1, 2020., 2020
Sandstone is different from pure brittle rocks such as marble and granite. Its brittleness weakens and then increases with increasing confining pressure. This paper establishes a calculation model of the “brittleness‐ductility” energy drop coefficient that characterizes the whole process of sandstone failure from the perspective of energy. The obtained

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

open access: yesPeople and Nature, Volume 8, Issue 7, Page 2212-2232, July 2026.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Palmitoylethanolamide (PEA) Induces an Increase in Spleen Regulatory T Cells, Reduces CD8 + Cells and TNF‐α Levels in Target Organs, and Protects Mice From Graft‐Versus‐Host Disease‐Related Mortality Through PPAR Activation Without Compromising the Graft‐Versus‐Tumour Response

open access: yesImmunology, Volume 176, Issue 3, Page 385-402, November 2025.
Effect of Palmitoylethanolamide (PEA) in a murine model of graft‐versus‐host disease (GVHD). Following an allogeneic transplant from C57BL/6J donors to BALB/c recipients, PEA treatment improved survival, alleviated clinical symptoms, and protected target organs in GVHD‐affected mice.
