Microprocessor Technology and Single Event Upset Susceptibility

, 1996
Today\u27s small satellites employ powerful microcircuits to control virtually every aspect of the spacecraft. While these small devices are very capable, they are increasingly vulnerable to heavy ion induced Single Event Upset (SEU).

The Impact of Soft Error on C-Elements Due to Process Corner Variation and Temperature

Journal of Applied Science & Process Engineering, 2015
This paper presents current injection resemble single event upset (SEU) current at the vulnerable nodes on different configurations of C-elements under two different scenarios: process corner and temperature. The objectives are to identify the vulnerable

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Single event upset hardening techniques [PDF]

, 1990
Integrated circuit logic states are maintained by virtue of specific transistor combinations being either on'' (conducting) or off'' (nonconducting). High energy ion strikes on the microcircuit generate photocurrents whose primary detrimental effect is ...
