A new thermonuclear $^{17}$O($n$,$\gamma$)$^{18}$O rate is derived based on a complete calculation of the direct-capture (DC) and resonant-capture contributions, for temperature region up to 2 GK astrophysical interest. We have firstly calculated DC subthreshold contributions in energy 1 MeV, estimated associated uncertainties by Monte-Carlo approach. It shows that present remarkably larger tha...

A diagonally switchable 4-cycle system of order n, briefly DS4CS(n), is a 4-cycle system in which by replacing each 4-cycle (a, b, c, d) covering pairs ab, bc, cd, da by either of the 4-cycles (a, c, b, d) or (a, b, d, c) another 4-cycle system is obtained. We prove that a DS4CS(n) exists if and only if n ≡ 1 (mod 8), n ≥ 17 with the possible exception of n = 17. AMS classification: 05B30

Nociceptin/orphanin FQ (N/OFQ) is a heptadecapeptide that is an endogenous ligand for the N/OFQ peptide (NOP) receptor. The aim of this study was to investigate the behavioral responses of N/OFQ and its major fragment N/OFQ(2-17) in monkeys following i.t. administration. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was used to quantify the amounts ...
