Voltage Stability Assessment Based on Modified Line Voltage Stability Index in the Presence of Renewable Energy Integration and Credible Contingencies

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
A modified line voltage stability index (MLVSI) is proposed to address limitations in the existing indices. The MLVSI is evaluated against Lmn, MVSI, and NCPI under varying load levels, renewable energy penetration, and contingency scenarios. It considers line resistance, power flow direction, and high‐loading events to identify critical lines and ...

Twists of automorphic L-functions at the central point

open access: yes, 2013
We study the nonvanishing of twists of automorphic L-functions at the centre of the critical strip. Given a primitive character \chi modulo D satisfying some technical conditions, we prove that the twisted L-functions L(f.\chi,s) do not vanish at s=1/2 ...

Anti-Pseudomonas fluorescens mechanism of plantaricin Q7 from Lactiplantibacillus plantarum Q7 based on proteomics

open access: yesFood Science of Animal Products
This study explored how plantaricin Q7 acts against Pseudomonas fluorescens at cellular and protein expression levels. Plantaricin Q7 exhibited a minimum inhibitory concentration (MIC) of 144 AU/mL against P. fluorescens. The scanning electron microscopy

Ribosomal protein L32 of Saccharomyces cerevisiae regulates both splicing and translation of its own transcript.

open access: yesJournal of Biological Chemistry, 1993
Ribosomal protein L32 of Saccharomyces cerevisiae regulates the splicing of its own transcript (1, 2) apparently by interacting with a structure composed largely of the 5' exon. However, even in strains overproducing L32 mRNA, e.g. from a cDNA copy of the gene, little accumulation of L32 is observed after a brief pulse label.

Quantization of symplectic tori in a real polarization

open access: yes, 1996
We apply the geometric quantization method with real polarizations to the quantization of a symplectic torus. By quantizing with half-densities we canonically associate to the symplectic torus a projective Hilbert space and prove that the projective ...

Modification of Aminoacyl tRNA Synthetase in Order to Incorporate an Unnatural Amino Acid [PDF]

open access: yes, 2018
Proteins allow daily processes in the cell to occur. A protein consists of amino acids. There are twenty natural amino acids coded for in the DNA of organisms. The natural amino acids can be modified to form unnatural amino acids (UAAs). UAAs have useful
