The Evolutionary Status of Isolated Dwarf Irregular Galaxies II. Star Formation Histories and Gas Depletion [PDF]

open access: yes, 2001
The results of UBV and H alpha imaging of a large sample of isolated dwarf irregular galaxies are interpreted in the context of composite stellar population models.

Quiescent Optical Solitons for the Concatenation Model with Nonlinear Chromatic Dispersion

open access: yesMathematics, 2023
This paper recovers quiescent optical solitons that are self-sustaining, localized wave packets that maintain their shape and amplitude over long distances due to a balance between nonlinearity and dispersion.

Mechanism and Optimized Design of Vehicle Quiescent Current

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract This paper analysed the quiescent current generation mechanism of vehicles and the four stages of quiescent current presentation during the vehicle rest process. Then the quiescent current is optimized from the perspective of ECU and vehicle electrical design.

First results from the VIRIAL survey: the stellar content of $UVJ$-selected quiescent galaxies at $1.5 < z < 2$ from KMOS [PDF]

open access: yes, 2015
We investigate the stellar populations of 25 massive, galaxies ($\log[M_\ast/M_\odot] \geq 10.9$) at $1.5 < z < 2$ using data obtained with the K-band Multi-Object Spectrograph (KMOS) on the ESO VLT.

Low-Quiescent Current Class-AB CMOS LDO Voltage Regulator

open access: yes2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018
A low-quiescent current output-capacitorless class-AB CMOS low-dropout voltage regulator (LDO) capable to source/sink current to/from the load is presented, which is suitable for hybrid or linear-assisted structures utilized in envelope elimination and restoration (EER) applications.

Activation of pancreatic stellate cells attenuates intracellular Ca2+ signals due to downregulation of TRPA1 and protects against cell death induced by alcohol metabolites

open access: yesCell Death and Disease, 2022
Alcohol abuse, an increasing problem in developed societies, is one of the leading causes of acute and chronic pancreatitis. Alcoholic pancreatitis is often associated with fibrosis mediated by activated pancreatic stellate cells (PSCs). Alcohol toxicity

A Fast-Transient-Response NMOS LDO with Wide Load-Capacitance Range for Cross-Point Memory

open access: yesSensors, 2022
In this paper, a fast-transient-response NMOS low-dropout regulator (LDO) with a wide load-capacitance range was presented to provide a V/2 read bias for cross-point memory.

A Panchromatic View of Brown Dwarf Aurorae [PDF]

open access: yes, 2017
Stellar coronal activity has been shown to persist into the low-mass star regime, down to late M-dwarf spectral types. However, there is now an accumulation of evidence suggesting that at the end of the main sequence there is a transition in the nature ...

Gambierol Blocks a K+ Current Fraction without Affecting Catecholamine Release in Rat Fetal Adrenomedullary Cultured Chromaffin Cells

open access: yesToxins, 2022
Gambierol inhibits voltage-gated K+ (KV) channels in various excitable and non-excitable cells. The purpose of this work was to study the effects of gambierol on single rat fetal (F19–F20) adrenomedullary cultured chromaffin cells.
