Patent rights in a duopoly with price leadership

open access: yesInternational Journal of Management and Economics
This study analyzes the impact of patent rights on duopolistic competition with price leadership. The willingness of companies with significant patent rights to form a cartel was assessed. The main aim of the analysis was to determine the role of patents

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 ...

Robust Finite‐Time Controller for Damping of Subsynchronous Resonance in Permanent Magnetic Synchronous Generator Wind Power System

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
From the energy perspective, this paper proposes a continuous robust finite‐time energy‐shaping controller (ESC) to achieve fast mitigation of subsynchronous resonance (SSR) in a PMSG‐based wind farm. ABSTRACT Subsynchronous resonance (SSR) poses a significant threat to the stability of permanent magnet synchronous generator (PMSG)‐based wind power ...

Optimized Directed Evolution of E. coli leucyl‐tRNA Synthetase adds many Noncanonical Amino Acids into the Eukaryotic Genetic Code Including Ornithine and Nϵ‐Acetyl‐Methyllysine

open access: yesAngewandte Chemie, Volume 137, Issue 14, April 1, 2025.
The pyrrolysyl pair has dominated noncanonical amino acids (ncAAs) incorporation in eukaryotes, but additional engineerable pairs are needed to further expand this toolbox. Although E. coli leucyl‐tRNA synthetase (EcLeuRS) is a promising candidate, engineering its substrate specificity has been much less successful.

Évaluation de la résistance aux nématodes à kystes des céréales, Heterodera avenae dans les lignées élites marocaines de blé dur et blé tendre

open access: yesAfrican and Mediterranean Agricultural Journal - Al Awamia
Les nématodes à kystes des céréales (Heterodera avenae) constituent une menace importante pour la production de blé en Afrique du Nord. Cette étude a évalué la résistance de 100 lignées élites de blé (51 lignées de blé dur et 49 lignées de blé tendre) du

Numerical Modeling for the Vibration Characteristics of Multistrata Composite Annular Disks of Spatially Uniform and Nonuniform Thickness Using Refined Higher‐Order Shear Deformation Theory

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This study introduces a novel numerical modeling of multistrata composite annular disks of spatially uniform and nonuniform thickness based on refined higher‐order shear deformation theory (HSDT), extending beyond conventional single‐layer and functionally graded models.

Mitochondrial ribosomal protein L41 mediates serum starvation-induced cell-cycle arrest through an increase of p21WAF1/CIP1

open access: yesBiochemical and Biophysical Research Communications, 2005
Ribosomal proteins not only act as components of the translation apparatus but also regulate cell proliferation and apoptosis. A previous study reported that MRPL41 plays an important role in p53-dependent apoptosis. It also showed that MRPL41 arrests the cell cycle by stabilizing p27(Kip1) in the absence of p53.

Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...
