MicroRNA (miR/miRNA)-21 is a well-known oncogenic miRNA that is overexpressed in various types of tumors. The tumor-suppressor genes programmed cell death 4 (PDCD4) and phosphatase tensin homologue (PTEN), are targets of miR-21, and are underexpressed in several types of cancer. However, the expression of miR-21 and its target genes in neuroblastoma (NB) remains unclear. In the present study, a...

It has been known that the transition probability of single species ASEP with $N$ particles is expressed as a sum $N!$ $N$-fold contour integrals which are related to permutations in symmetric group $S_N$. On other hand, probabilities multi-species ASEP, general, may be much more terms than $N!$. In this paper, we show if initial order given by $2\cdots 21$, $12\cdots 2$, $1\cdots 12$ or $21\cd...

Candidate global minimum structures are reported for (H2O)n clusters for n 6 21 described by the rigid-body TIP5P potential. These structures are compared with previously published results for the related TIP4P potential, and with ab initio calculations at the MP2 level. The variation of the energy gap from the putative global minimum to the next-lowest structure as a function of system size is...

We show that the analytic continuations of Helson zeta functions ζ χ ( s ) = ∑ 1 ∞ n − $ \zeta _\chi (s)= \sum _1^{\infty }\chi (n)n^{-s}$ can have essentially arbitrary poles and zeroes in strip 21 / 40 < ℜ 21/40 \Re 1$ (unconditionally), whole critical 2 1/2 <1$ under Riemann Hypothesis, with function \chi$ taking values cubic roots unity. If sets are symmetric respect to real axis, same be a...
