Key Transmission Section Search Based on Graph Theory and PMU Data for Vulnerable Line Identification in Power System

open access: yesJournal of Electrical and Computer Engineering, 2023
Failure of vulnerable lines in the power system often results in tidal shifts, and triggering chain failures and their corresponding transmission sections are concentrated manifestations of the weak links in the power system.

Spin-orbit conversion at the sharp focus of a circularly polarized light beam

open access: yesКомпьютерная оптика
It is known that when tightly focusing a circularly polarized optical vortex, spin-to-orbital angular momentum conversion occurs. It is usually said that the longitudinal component of the spin angular momentum (SAM) vector is transformed into the ...

Insight Into the Dynamics of the Rabinowitsch Fluid Through an Elliptic Duct: Peristalsis Analysis

open access: yesFrontiers in Physics, 2022
The current research is concerned with the mechanical characteristics of a Rabinowitsch fluid model that has been developed via an elliptic duct. If we study physiology or biomedicine, we will find that the Rabinowitsch fluid model in peristalsis is very

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
