The FMU and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) concluded that the high incidence of thyroid cancer after the Fukushima nuclear accident was not the result of radiation exposure, but rather might have been overdiagnosis based on the low thyroid dose estimated in the UNSCEAR 2020/2021 report. In this study, the origin of increased PTC in Fukushima was examined based on the thyroid dose estimated by UNSCEAR. The dose-response relationship of the incidence rate per person-years (PY) was analyzed for four areas in Fukushima prefecture via regression analysis.

Main Methods: Whole-cell patches were made from cultured rat dorsal root ganglion (DRG) neurons and heat-activated currents were monitored.
Key Findings: A temperature rise from 25 to 45 degrees C generated outward currents with the current/voltage relation revealing a reversal potential of approximately -90 mV, that are inhibited by the K+ channel blockers, Ba2+ and tetraethylammonium, indicating that heat activates K+ channels expressed in DRG neurons.
We study theoretically heavy fermion superconductors CeMIn(5) (M = Co, Rh, Ir). CeCoIn(5) and CeIrIn(5) that become superconducting at ambient pressure with T(c) = 2.3 K and 0.

In particular, we focus on the effects due to the sudden disappearance of the image potential in the neutralization process. From the analysis, we found that the neutralization probability is given by [Formula: see text], where D and Γ are the band width and the gamma function.
