The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

open access: yes, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Single-Level and Two-Level Circuit Solutions for Buck-Boost AC Voltage Regulators with Phase-by-Phase Switches

open access: yesElectricity
Forming required AC voltage levels is currently one of the most pressing problems. Unstable voltage levels can lead to the failure of household and industrial equipment. This can lead to a pure effect on the production cycle.

Voltage-Gated Potassium Channels as Regulators of Cell Death

open access: yesFrontiers in Cell and Developmental Biology, 2020
Ion channels allow the flux of specific ions across biological membranes, thereby determining ion homeostasis within the cells. Voltage-gated potassium-selective ion channels crucially contribute to the setting of the plasma membrane potential, to volume

Evaluating Resilience of Electricity Distribution Networks via A Modification of Generalized Benders Decomposition Method

open access: yes, 2020
This paper presents a computational approach to evaluate the resilience of electricity Distribution Networks (DNs) to cyber-physical failures. In our model, we consider an attacker who targets multiple DN components to maximize the loss of the DN ...

Flexible on‐load voltage regulating transformer based on common‐capacity‐midpoint two‐half‐bridge converter

open access: yesIET Power Electronics
Traditional on‐load voltage regulating transformer are composed of segmented windings controlled by tap changers and power frequency transformers. The tap changer can only perform ‘step‐wise voltage regulation’ and is slow in response.
