212Pb is differentiated as both an alpha and beta-emitting isotope with a simple decay chain that has demonstrated promising clinical results1in compassionate use and phase 1 settings.212Pb is produced via a generator using thorium (228Th, 1.9 year half-life) or...
There are four radioactive isotopes of lead: 210 Pb and 214 Pb in the 238 U decay chain, 211 Pb in the 235 U decay chain, and 212 Pb in the 232 Th decay chain. All except 210 Pb have half-lives of less than 12 hours. Such short half-lives are of limited usefulness in geology...
Only one of the stable, naturally occurring lead isotopes, 204Pb, is nonradiogenic, whereas other lead isotopes are end products of one of three series of radioactive decay: the uranium series (end product: 206Pb), thorium series (208Pb), and actinium series (207Pb). As a consequence, ...
The faint emission of derivatives 2-ArR and 3-Ar35-CF3 was hypothesized to arise from non-radiative decay pathways from lower-energy excited states triggered by inter-ligand transitions in 2-ArR or ligand-to-metal charge transfer events in 3-Ar35-CF3. In summary, the outcomes broaden the ...
This may be due to the recognition of specific sets of mutated mRNAs by RNA-binding proteins, which serve as adaptors and control decay rates by recruitment of RNA-degrading enzymes.34 The reduced mRNA abundance in low-motility sperm was also previously observed for other members (such as DNA...
Bayesian Inference (BI) analysis was performed with MrBayes (ver. 3.2.5)46 using a Markov Chain Monte Carlo (MCMC) algorithm. Appropriate nucleotide substitution models and parameters were determined by using the program Modeltest (ver. 3.7)47. Four MCMC chains (one cold and three heated) ...
Polonium-210 arises from lead-210 decay and is a widespread alpha-emitting radionuclide. It seeks soft tissue and has the potential to accumulate in the food chain. Caribou, wolves and other wildlife may become exposed to enhanced levels of these two uranium-series radionuclides if the proposed ...

Each nonzero element in 𝐏L is the matrix element for the terminal atom p of the inverse Green’s function of the semi-infinite linear chain, g−1L. The molecule block is the characteristic matrix constructed from the molecular adjacency matrix, 𝐀M, 𝐏M=𝐸𝟏−𝐀M=𝐔(𝐸...
On the other hand, the s-process, occurs over much longer timescales, and in environments with relatively lower neutron densities (n ≤ 101111 cm−3−3) such that the less stable nuclei can undergo beta decay. Observational studies have shown that the astrophysical sites of the s-process ...
