Heat-pump performance: voltage dip/sag, under-voltage and over-voltage
The Journal of Engineering, 2014 Reverse cycle air-source heat-pumps are an increasingly significant load in New Zealand and in many other countries. This has raised concern over the impact wide-spread use of heat-pumps may have on the grid. The characteristics of the loads connected to

Dynamics of voltage instability and collapse
International Journal of Electrical Power & Energy Systems, 1994 Abstract This paper presents a dynamic voltage stability analysis of the effects of time-varying loads. The stability of a power system is shown to be dependent not only on maximum loading levels, but also on the transition of the system from one loading level to another.

Controlling Chaos and Voltage Collapse using Layered Recurrent Network-based PID-SVC in Power Systems [PDF]
, 2013 Chaos and voltage collapse occurred in critical power systems due to disturbing of energy. PID-SVC layered reccurrent neural network-based (LRN-based PID-SVC) was proposed to solve these problems.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function
FEBS Open Bio, EarlyView.Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

GECM-Based Voltage Stability Assessment Using Wide-Area Synchrophasors
Energies, 2017 Voltage instability is a crucial issue in the secure operation of power grids. Several methods for voltage stability assessment were presented. Some of them are highly computationally intensive, while others are reported not to work properly under all ...

Distributed Monitoring of Voltage Collapse Sensitivity Indices
IEEE Transactions on Smart Grid, 2016 The assessment of voltage stability margins is a promising direction for wide-area monitoring systems. Accurate monitoring architectures for long-term voltage instability are typically centralized and lack scalability, while completely decentralized approaches relying on local measurements tend towards inaccuracy.

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis
FEBS Open Bio, EarlyView.Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...
