positively on the number of methoxyl groups on the benzyl moiety, and the homopiperazine analogs seem to be equipotent to the corresponding piperazines. From the standpoints of potency and ease of synthesis, 8k was selected for further study. Further analogs, which have various substituents in place of the benzyl moiety of 8k, were prepared and tested for cerebral vasodilating activity. These a...

A double Roman dominating function on a graph G=(V,E) is f:V?{0,1,2,3} satisfying the condition that every vertex u for which f(u)=0 adjacent to at least one assigned 3 or two vertices 2, and with f(u)=1 2 3. The weight of f equals w(f)=?v?Vf(v). domination number ?dR(G) G minimum G. We obtain closed expressions generalized Petersen graphs P(5k,k). It proven ?dR(P(5k,k))=8k k?2,3mod5 8k??dR(P(5...

NHK STRL NHK has developed a 22.2 multichannel sound (22.2 sound) system for 8K Super Hi-Vision (8K), an ultra high-defi nition TV. The system consists of 24 spatially arranged audio channels including two low frequency effect (LFE) channels for reproducing threedimensional spatial sound. To respond to various viewing circumstances of 8K in homes, we have also developed several reproduction met...

A variant of the Nielsen–Ninomiya no-go theorem is formulated. This theorem states that, under several assumptions, it is impossible to write down a doubler-free Euclidean lattice action of a single Majorana fermion in 8k and 8k + 1 dimensions. ∗) E-mail: [email protected] 1 typeset using PTPTEX.cls 〈Ver.0.9〉

Various endoscopic devices have been developed for advanced minimally invasive surgery. We recently applied a new 8K ultra-high-definition television system during laparoscopic treatment of endometriosis. The procedure, which is described in detail, stands as the first reported application of an 8K ultra-high-definition system for laparoscopic gynecologic surgery. Comparison is made between dep...

Potato mop-top virus (PMTV) produces a defective RNA (D RNA) encompassing the 5'-terminal 479 nucleotides (nt) and 3'-terminal 372 nt of RNA-TGB (where TGB is triple gene block). The mechanism that controls D RNA biogenesis and the role of D RNA in virus accumulation was investigated by introducing deletions, insertions, and point mutations into the sequences of the open reading frames (ORFs) o...
