Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs Worldwide. [PDF]

Glob Chang Biol
Based on a global analysis of 1921 soil samples, we show that agricultural management acts as a powerful ecological filter reshaping microbial communities. Land use and inputs—pesticides and fertilizers—drive a functional shift toward opportunistic pathogens and fragmented, less connected microbial networks, potentially compromising soil ecosystem ...

A Novel Spatio-Temporal Fully Meshless Method for Parabolic PDEs

Mathematics, 2022
We introduce a meshless method derived by considering the time variable as a spatial variable without the need to extend further conditions to the solution of linear and non-linear parabolic PDEs.

Unveiling the “Gray Zone”: Characterizing Young People's Moderate STEM Identities

Journal of Research in Science Teaching, Volume 63, Issue 7, Page 691-711, September 2026.
ABSTRACT Understanding how students identify with STEM (Science, Technology, Engineering, Mathematics) is crucial for fostering broader and more equitable participation within these fields. While existing research has focused on students who either strongly identify with STEM or disengage from it, this study explores the moderate STEM identities of ...

Bianchi I Spacetimes in f(Q)‐Gravity

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT The Kasner spacetimes are exact solutions that are self‐similar and of significant interest because they can describe the dynamic evolution of kinematic variables near the singularity of the Mixmaster universe. The chaotic behavior of the Mixmaster universe is related to the Kasner relations.

Sensitivity and Hamming Graphs

Journal of Graph Theory, Volume 112, Issue 3, Page 296-305, July 2026.
ABSTRACT For any m ≥ 3 we show that the Hamming graph H ( n , m ) admits an imbalanced partition into m sets, each inducing a subgraph of low maximum degree. This improves previous results by Tandya and by Potechin and Tsang, and disproves the Strong m‐ary Sensitivity Conjecture of Asensio, García‐Marco, and Knauer.
