A “Conveyor Belt” From International Standards to Domestic Regulation? Evidence From the International Political Economy of Net Zero Governance

Regulation &Governance, EarlyView.
ABSTRACT When and how do international standards influence domestic policies? The literature identifies a range of ways international standards may relate to domestic regulations—including by exporting, substituting, supplanting, or bolstering national rules—creating theoretical ambiguity.

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Research on Dynamic Characteristics of Electromechanical Coupling for the Ultra‐Compact Wind Turbines

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT With the development of ultra‐compact wind turbines, the electromechanical coupling dynamic characteristics of integrated gearbox‐generator systems in their drive trains have attracted increasing attention. To reveal these characteristics, an electromechanical coupling dynamic model is established using the lumped parameter method and the ...
