physica status solidi (b), Volume 263, Issue 3, March 2026.Vacancies in low‐dose ion‐implanted GaN are studied by positron annihilation. Depth profiles of the net donor concentration (ND) are close to those for implanted impurities, but ND is 2–3 times higher than concentrations of implanted ions. The origin of donor‐like defects is expected to be N‐vacancy‐related defects, and Ga‐vacancy‐type defects play a ...

Weight Systems from Feynman Diagrams
Journal of Knot Theory and Its Ramifications, 1998 We find that the overall UV divergences of a renormalizable field theory with trivalent vertices fulfil a four-term relation. They thus come close to establish a weight system. This provides a first explanation of the recent successful association of renormalization theory with knot theory.

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice
Small Methods, Volume 10, Issue 5, 9 March 2026.Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.
