However, scientists in the toxicology and risk assessment community are still at odds over the issue of whether threshold doses exist for adverse responses (Crawford and Wilson 1996; Crump et al. Molecular signaling network motifs provide a mechanistic basis for cellular threshold responses The minimu...

The threshold shifts at the various dose rates and temperatures are compared. The total threshold shifts are separated into the contributions from interface states and trapped oxide charge. The results show different damage levels for tests at the different dose rates, and annealing of the threshold...
Testing of longitudinal lymph node biopsies showed that vDNA copy number was stable in individual animals over time, mirroring the data in PBMCs and consistent with viral measures of plasma viral RNA and outgrowth of inducible virus from tissues. A key advantage of bNAbs over ART is the ...

For these reasons, methods that improve information transfer over a wide range of spatial frequencies are required. One solution is to introduce a phase shifting device in the back focal plane of the objective lens and both Zernike8 and Volta phase plates9 which introduce a phase shift between ...
The voltage noise power spectral density $S_{rm Vd}$ is proportional to $(V_{g} - V_{t})^{-beta}$, where $V_{t}$ is the threshold voltage, $V_{g}$ is the gate voltage, and $beta$ is a measure of the gate-voltage dependence. For the pMOS devices, preirradiation $ beta$...
