Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Precipitation is scarce in arid regions, making water redistribution a key driver of vegetation patterns, especially for non‐zonal vegetation in oases. Nevertheless, the coupling and mutual feedback mechanism between water and vegetation distribution is complex, and it has not been fully addressed. Taking an arid region of Northwest China as a

The principles of systems biology
Experimental Physiology, Volume 111, Issue 5, Page 2438-2448, 1 May 2026.Abstract Physiological interpretations of Systems Biology have made many advances since the Principles of Systems Biology were first published in this journal in 2008. Those advances show that the main principle, Biological Relativity, is a logical necessity since no system can exist without the form of the system.
