Molecular Basis for Vacuolar Iron Transport by OsVIT2, a Target for Iron Biofortification in Rice

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 10, Page 1717-1731, October 2025.
ABSTRACT Iron deficiency is the prevalent and most widespread nutritional shortfall for humans, affecting over 30% of the global population and leading to anemia, particularly among preschool‐aged children and pregnant women in developing countries. Simultaneously, while half of the world's population depends on rice (Oryza sativa L.) as a staple food,

An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines

Alexandria Engineering Journal
As a large percentage of faults in transmission lines are single-line-to-ground (SLG) and transient in nature, the use of adaptive single-phase auto-reclosing (ASPAR) schemes is essential.

Improved digital algorithm for adaptive reclosing for transmission lines with shunt reactors

IET Generation, Transmission & Distribution, 2016
This study presents an improved algorithm of adaptive single‐phase auto‐reclosing (ASPAR) for extra high voltage transmission lines with shunt reactors. It shows that the odd and even harmonic factors of the faulted phase voltage have different characteristic in different stages after breaker open.

Adaptive Single Phase Auto-Reclosing Using Voltage Magnitude Pattern

, 2020
This paper presents a novel adaptive single phase auto-reclosing (ASPAR) scheme based on the first derivation of local voltage magnitude (VM) of the faulted phase for determination of dead time of transient faults. The algorithm is fast and uses low-frequency sampling and adaptive threshold value (ATV).
