Electromagnetic and Mechanical Stress Analysis of a 5 MW High-Pole Non-Overlap Winding Wound-Rotor Synchronous Wind Generator

Energies
Utilizing non-overlap windings has emerged as a favourable choice for minimizing electrical machine manufacturing costs, among other benefits. Nevertheless, it is widely acknowledged that these windings exhibit a notable level of harmonic contents in the resultant magnetomotive force, which can detrimentally impact machine performance, particularly in ...

Wood Sawdust as a Low‐Cost Filler in Whole‐Tire Reclaimed Rubber: Mechanical Characterization and Factory‐Scale Cost Analysis

Journal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Whole‐tire reclaimed rubber is upgraded with wood sawdust, a carpentry by‐product available at no cost, across loadings from 0 to 20 wt%. At 5 wt%, tensile strength, elongation, hardness, viscosity, and water absorption all stay within commercial specification, and real factory data show an annual production saving near $62,000 with no capital ...

Crowder‐specific modulation of hepatitis C virus NS3/4A protease activity and local structural dynamics

Protein Science, Volume 35, Issue 11, November 2026.
Abstract Macromolecular crowding modulates enzyme behavior in crowder‐ and protein‐specific ways, yet its impact on viral proteases, which are often key therapeutic targets, remains unclear. Here, we investigated the hepatitis C virus NS3/4A protease under increasing concentrations of polyethylene glycols (PEGs), ficoll, dextran, and lysozyme using ...

Dietary Echinacea purpurea Attenuates Oxidative Stress and Alters Cytokine Gene Expression Among Heat‐Stressed Broiler Chickens at High Altitude

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Dietary Echinacea purpurea (0.75%) alleviated oxidative stress (↓NO, ↓MDA) and selectively upregulated IL‐10 and IFN‐γ expression in heat‐stressed broilers at high altitude, shifting the cytokine balance toward an anti‐inflammatory state without affecting telomere length.

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

Synthesis and Fluorescence Profiling of Naphthylamine Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
N‐phenyl‐1‐naphthylamine (NPN) has been historically used as a probe to monitor gram‐negative bacterial outer membrane permeabilization, fluorescing only in hydrophobic environments. Herein, a 95‐membered naphthylamine library was synthesized to explore structure–fluorescence relationships, informed by density functional theory studies.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, Volume 2, Issue 5, October 2026.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
