Phenological Shifts in Autumn Drive Changes in Ice‐on Timing and Under‐Ice Water Temperature in Dimictic Finnish Lakes

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Autumn is a pivotal but understudied season in limnology. As climate change alters the timing and duration of autumnal cooling, the implications for winter thermal structure and long‐term ecosystem function in dimictic lakes remain uncertain.

Quantitative Difference Between the Effective Inertia and Set Inertia Parameter of Virtual Synchronous Generators

Energies
Virtual synchronous generators (VSGs) have been developed to mitigate the increase in the rate of change of frequency (ROCOF) in power systems by replacing synchronous generators (SGs) with inverter-based resources. VSGs mimic the dynamics and control of
