A Simulation-Based Optimization Method for Hybrid Frequency Regulation System Configuration

open access: yesEnergies, 2017
Frequency regulation is essential for the stability of a power grid with high load fluctuation and integration of new energies. Constrained by the large ramping, a generator alone is not capable of conducting load frequency controls effectively and ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Cholinergic regulation of impulse frequency in peripheral nerve

open access: yesBrain Research, 1987
Previous studies have demonstrated the existence of receptors for gamma-aminobutyric acid (GABA), beta-adrenergic catecholamines and acetylcholine in vertebrate peripheral nerve, and provided functional correlates for activation of both GABA and beta-adrenergic receptors.

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates

open access: yesFEBS Letters, EarlyView.
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.
