The Time Response of a Uniformly Doped Transmission-Mode NEA AlGaN Photocathode Applied to a Solar-Blind Ultraviolet Detecting System

Photonics
Due to the excellent quantum conversion and spectral response characteristics of the AlGaN photocathode, it has become the most promising III-V group semiconductor photocathode in solar-blind signal photoconversion devices in the ultraviolet band. Herein,

Characterising Backscattered Electrons in EBCMOS

IEEE Photonics Journal, 2022
The characteristics of backscattered electrons near the surface of a back-side bombarded CMOS (BSB-CMOS) within an electron bombarded CMOS (EBCMOS) were studied based on the principle of electron-solid interactions and Monte-Carlo simulation method.

Low-level seaweed supplementation improves iodine status in iodine-insufficient women [PDF]

, 2014
Iodine insufficiency is now a prominent issue in the UK and other European countries due to low intakes of dairy products and seafood (especially where iodine fortification is not in place).

Low level signal limiter [PDF]

, 1968
A limiting circuit is described which prevents a signal being supplied to a signal amplifier from exceeding a predetermined value. The circuit is designed to permit a signal voltage to be fed directly to a signal amplifier without passing through the ...

Retention of 2011 Fukushima Dai-ichi NPP accident-derived 137Cs in the northern North Pacific–Bering Sea

Scientific Reports
Tracing soluble radionuclides is critical for understanding the mechanisms underlying the transport of soluble materials in marine environments. In the present study, we investigated the surface distribution of the concentrations (activities) of 134Cs ...

Numerical simulation of outgassing characteristics of microchannel plate glass

AIP Advances, 2021
Outgassing of internal materials is one of the main factors that cause vacuum deterioration of low-light-level image intensifiers and shorten their lifetime (especially storage lifetime).

Bistability and chaos at low-level of quanta

, 2013
We study nonlinear phenomena of bistability and chaos at a level of few quanta. For this purpose we consider a single-mode dissipative oscillator with strong Kerr nonlinearity with respect to dissipation rate driven by a monochromatic force as well as by

Low level accelerometer test methods are investigated [PDF]

, 1966
Problems associated with testing accelerometers to an accuracy where the standard error is less than .0000001 g are centered around the elimination of uncertainties in the acceleration input to the accelerometer.

A Developmental Approach for low-level Imitations [PDF]

, 2003
Historically, a lot of authors in psychology and in robotics tend to separate "true imitation" and its related high-level mechanisms which seem to be exclusive to human adult, from low-level imitations or "mimicries" observed on babies or primates ...
