A graph G $G$ is called 3-choice-critical if not 2-choosable but any proper subgraph of 2-choosable. strongly fractional r $r$ -choosable ( a , b ) $(a,b)$ for all positive integers $a,b$ which ∕ ≥ $a\unicode{x02215}b\ge r$ . The strong choice number c h f s = inf { : $c{h}_{f}^{s}(G)=\text{inf}\{r:G$ } $\}$ This paper determines the graphs.

background: one of the key techniques for the preparation of 125i seeds is adsorption of 125i onto silver bits coated by palladium (pd). carriers played an important role in the adsorption of 125i on palladium. ki is used as a carrier for fixing of 125i onto silver wire bits coated with palladium. materials and methods: three procedures ki, koh, nh4oh were investigated for adsorption of 125i ac...

background and aims: epigallocatechin-3-gallate (egcg) is a polyphenolic compound from green tea, which its anticancer effects on many types of cancers have been confirmed, but the molecular mechanism by which egcg induces apoptosis remains unknown. the aim of the present study was to investigate anti-proliferative properties and apoptotic signaling pathway of egcg on pc3 human prostate cancer ...

objective(s):valproic acid (vpa), a drug used in the treatment of neurological disorders, has been shown to have cytotoxic effects on cancer cells through different mechanisms. telomerase, a ribonucleoprotein reverse transcriptase, is responsible for elongation of the telomere and is activated in cancers. a relation between telomerase activity and resistance to apoptosis has been established. t...

A new approach to probability theory based on quantum mechanical and Lie algebraic ideas is proposed and developed. The underlying fact is the observation that the coherent states of the Heisenberg-Weyl, su(2), su(r+1), su(1, 1) and su(r, 1) algebras in certain symmetric (bosonic) representations give the “probability amplitudes” (or the “square roots”) of the well-known Poisson, binomial, mult...
