Synthetic Organic Electrochemistry in Ionic Liquids: The Viscosity Question

Molecules, 2011
Ionic liquids are obvious candidates for use in electrochemical applications due to their ionic character. Nevertheless, relatively little has been done to explore their application in electrosynthesis.

Reduced-order dynamic model for droop-controlled inverter/converter-based low-voltage hybrid AC/DC microgrids – Part 2: DC sub-microgrid and power exchange

IET Smart Grid, 2018
This study focuses on reduced-order dynamical modelling of droop controlled converter-based DC sub-microgrid (MG) in a hybrid AC/DC MG. In hybrid MGs, electrical power is exchanged between the AC and DC sub-MGs by a bidirectional AC/DC converter.

Renormalisation Group Flows and Conserved Vector Currents

, 1994
Irreversibility of RG flows in two dimensions is shown using conserved vector currents. Out of a conserved vector current, a quantity decreasing along the RG flow is built up such that it is stationary at fixed points where it coincides with the constant

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Design of Programmable LED Controller with a Variable Current Source for 3D Image Display

Information, 2014
Conventional fluorescent light sources, as well as incandescent light sources are gradually being replaced by Light Emitting Diodes (LEDs) for reducing power consumption in the image display area for multimedia application. An LED light source requires a

Constant and switched bias low frequency noise in p-MOSFETs with varying gate oxide thickness [PDF]

, 2002
The low-frequency noise power spectral density of MOSFETs is decreased if the MOSFETs are periodically switched 'off' (switched bias conditions). The influence of the gate oxide thickness on fixed bias and switched biased low frequency drain current ...
