Transient stability analysis of virtual synchronous generator with current saturation by multiple Lyapunov functions method

IET Generation, Transmission & Distribution
This paper demonstrates that the switching of one grid‐connected virtual synchronous generator (VSG) between two control modes, namely constant voltage control (CVC) and current limiting control (CLC) happens at the derived two switching lines.

Self-organising technique for carrier synchronisation and phase offset distribution in modular, fault-tolerant converters

The Journal of Engineering, 2019
Carrier interleaved pulse width modulated modular multilevel converters provide multiple benefits including increased effective switching frequency, switching frequency harmonic elimination, and reduced filter requirements. For converters comprising high

New 5 Kilowatt Free-piston Stirling Space Convertor Developments [PDF]

, 2007
The NASA Vision for Exploration of the moon may someday require a nuclear reactor coupled with a free-piston Stirling convertor at a power level of 30-40 kW. In the 1990s, Mechanical Technology Inc.

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

Molecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Power cable stresses caused by transmission line faults in next generation VSC-MMC systems

The Journal of Engineering, 2019
Until today, HVDC systems based on Modular Multilevel Voltage Source Converters (VSC-MMC) have exclusively been realised with cross-linked polyethylene (XLPE) cable transmission in monopolar configuration.

Predictors of response and rational combinations for the novel MCL‐1 inhibitor MIK665 in acute myeloid leukemia

Molecular Oncology, EarlyView.
This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...
