A Voronoi Diagram‐Based Approach for AC Optimal Power Flow

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

K^*(BG) rings for groups $G=G_{38},...,G_{41}$ of order 32

, 2013
B. Schuster \cite{SCH1} proved that the $mod$ 2 Morava $K$-theory $K(s)^*(BG)$ is evenly generated for all groups $G$ of order 32. For the four groups $G$ with the numbers 38, 39, 40 and 41 in the Hall-Senior list \cite{H}, the ring $K(2)^*(BG)$ has been

Microbial and Metabolomic Variations Correlated With Gastric Cancer Subtypes and Prognosis

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Multi‐omics analysis of 50 GC patients revealed conserved microbial‐metabolite signatures across Lauren/ZJU subtypes, with ZJU‐specific features—Eubacterium_ventriosum_group and N6‐Succinyl Adenosine—enabling superior prognostic stratification. ABSTRACT Gastric cancer (GC) persists as the third most prevalent malignancy in China.

Correlation analysis between the delayed rectifier potassium channel KCNE1 (G38S) polymorphism and atrial fibrillation among the senior Uygur population in Xinjiang

Genetics and Molecular Research, 2015
Current resources to support genetic screening among the Uygur population in Xinjiang territory for atrial fibrillation (AF) have not been well established and large-scale epidemiological analyses are needed. Using patients from the Xinjiang Uygur population as subjects, and the delayed rectifier potassium channel KCNE1 and its associated polymorphism ...
