Dual Frequency Regulation in Pumping Mode in a Wind–Hydro Isolated System
Energies, 2018 Frequency control is one of the most critical tasks in isolated power systems, especially in high renewable penetration scenarios. This paper presents a new hydropower pumped-storage dual control strategy that combines variable-speed-driven pumps and ...

Temperature Regulation in Multicore Processors Using Adjustable-Gain Integral Controllers
, 2015 This paper considers the problem of temperature regulation in multicore processors by dynamic voltage-frequency scaling. We propose a feedback law that is based on an integral controller with adjustable gain, designed for fast tracking convergence in the

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

An Integrated Frequency Regulation Method Based on System Frequency Security Posture
EnergiesAs the share of renewable energy in a grid increases, the grid’s frequency support capability weakens, and the spatial distribution of grid frequency becomes more pronounced.

Cholinergic regulation of impulse frequency in peripheral nerve
Brain 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.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

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