It is known that two cases of the polynomial spectral factorization are used in applications: the polynomial "discrete" spectral factorization (s) cp( — s) and all roots of the polynomial cp(s) have nonpositive real parts. It is suppos...

We consider mapping class groups Γ(M) = π0Diff(M fix ∂M) of smooth compact simply connected oriented 4–manifolds M bounded by a collection of 3– spheres. We show that if M contains CP 2 or CP 2 as a connected summand then all Dehn twists around 3–spheres are trivial, and furthermore, Γ(M) is independent of the number of boundary components. By repackaging classical results in surgery and handle...

Penaeus stylirostris densovirus (PstDNV) genome contains three open reading frames (ORFs), left, middle, and right, which encode a non-structural (NS) protein, an unknown protein, and a capsid protein (CP), respectively. Transcription mapping revealed that P2, P11 and P61 promoters transcribe the left, middle and right ORFs. NS transcript uses the D1/A1 donor/acceptor sites for splicing and has...

The knowledge-based Toxtree expert system (SAR approach) was integrated with the statistically based counter propagation artificial neural network (CP ANN) model (QSAR approach) to contribute to a better mechanistic understanding of a carcinogenicity model for non-congeneric chemicals using Dragon descriptors and carcinogenic potency for rats as a response. The transparency of the CP ANN algori...

Abstract A highly efficient and stable heterogeneous coordination polymer (CP) was successfully prepared by hydrothermal combination of silver 4,6-diamino-2-pyrimidinethiol. The characterized FT-IR, XRD, TGA, SEM, EDX, X-ray mapping Nitrogen adsorption–desorption analysis. Ag–CP exhibit excellent catalytic activity in multicomponent Hantzsch synthesis polyhydroquinolines under mild reaction con...

We consider normal covers of CP with abelian deck group, branched over at most four points. Families of such covers yield arithmetic Teichmüller curves, whose period mapping may be described geometrically in terms of Schwarz triangle mappings. These Teichmüller curves are generated by abelian square-tiled surfaces. We compute all individual Lyapunov exponents for abelian squaretiled surfaces, a...

AIMS The parasympathetic nervous system is thought to play a key role in atrial fibrillation (AF). Since parasympathetic signalling is primarily mediated by the heterotrimeric G-protein, Galpha(i)betagamma, we hypothesized that targeted inhibition of Galpha(i) interactions in the posterior left atrium (PLA) would modify the substrate for vagal AF. METHODS AND RESULTS Cell-penetrating(cp)-Galp...

This paper explores the linguistic properties of a discourse variant temporal adverb ʔelħi:n, used in Haili Dialect Najdi Arabic (HA). Maintaining characteristic co-occurring clause-initially, and examining lexical/discoursal articulated structures, ʔelħi:n has developed conventionalized use, turning its morphology into particle that expresses degree speaker’s attitude. undergone process gramma...
