Tolerance to Gamma Radiation in the Tardigrade Hypsibius dujardini from Embryo to Adult Correlate Inversely with Cellular Proliferation. [PDF]

PLoS ONE, 2015
Tardigrades are highly tolerant to desiccation and ionizing radiation but the mechanisms of this tolerance are not well understood. In this paper, we report studies on dose responses of adults and eggs of the tardigrade Hypsibius dujardini exposed to ...

Optical Multi-Context Blind Scrubbing for Field Programmable Gate Arrays

IEEE Photonics Journal, 2020
This paper presents aproposal of a new optical multi-context blind scrubbing that can not only increase the soft-error tolerance of the configuration memory of field programmable gate arrays (FPGAs) but also support high-speed dynamic reconfiguration ...

Ultraviolet radiation‐induced tolerance [PDF]

Allergy, 1999
Ultraviolet (UV) radiation is one of the most important environmental factors. Besides its well-known advantages and its indispensable effects on human life, UV light, particularly the middle wavelength range (290-320 nm [UVB]), can harm human health by inducing skin cancer, premature skin aging, inflammation, and cell death (1-4).

Effect of gamma-rays on recombination dynamics and defect concentration in a wide bandgap perovskite

Light: Advanced Manufacturing
Herein, we have explored the recombination dynamics and defect concentration of a mixed cation mixed halide perovskite Cs0.17FA0.83PbI1.8Br1.2 with 1.75 eV bandgap after exposure to a gamma-ray source (2.5 Gy/min).

Tolerance to gamma-irradiation in eggs of the tardigrade Richtersius coronifer depends on stage of development

Journal of Limnology, 2013
Tardigrades are known as one of the most radiation tolerant animals on Earth, and several studies on tolerance in adult tardigrades have been published. In contrast, very few studies on radiation tolerance of embryonic stages have been reported.

Improving radiation tolerance with room temperature annealing of pre-existing defects

Applied Physics Express
Pre-existing defects in semiconductor devices can act as nucleation sites for radiation damage. Defects generated from mismatches in lattice constant, stiffness and thermal expansion are difficult to eliminate with thermal annealing.
