Hardening electronic devices against very high total dose radiation environments [PDF]

open access: yes, 1972
The possibilities and limitations of hardening silicon semiconductor devices to the high neutron and gamma radiation levels and greater than 10 to the eighth power rads required for the NERVA nuclear engine development are discussed. A comparison is made

The impact of repetitive unclamped inductive switching on the electrical parameters of low-voltage trench power nMOSFETs [PDF]

open access: yes, 2010
The impact of hot-carrier injection (HCI) due to repetitive unclamped inductive switching (UIS) on the electrical performance of low-voltage trench power n-type MOSFETs (nMOSFETs) is assessed.

A novel radiation-dependence model of InP HBTs including gamma radiation effects

open access: yesNuclear Engineering and Technology, 2023
In order to predict the lifetime of InP Heterojunction Bipolar Transistor (HBT) devices and related circuits in the space radiation environment, a novel model including gamma radiation effects is proposed in this paper. Based on the analysis of radiation-

Anaphase B. [PDF]

open access: yes, 2016
Anaphase B spindle elongation is characterized by the sliding apart of overlapping antiparallel interpolar (ip) microtubules (MTs) as the two opposite spindle poles separate, pulling along disjoined sister chromatids, thereby contributing to chromosome ...
