High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, Volume 14, Issue 3, Page 1286-1299, March 2026.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Conformational Trajectory of the Molecular Chameleon Grazoprevir From Formulation to Target‐Bound

Chemistry – A European Journal, Volume 32, Issue 8, 23 February 2026.
ABSTRACT Macrocycles represent a promising class of beyond‐rule‐of‐5 (bRo5) therapeutics, capable of targeting proteins traditionally considered undruggable by conventional small molecules. Macrocycles exhibit intrinsic flexibility and often display a “chameleon‐like” ability to adapt to their environment, thereby enhancing their oral bioavailability ...
