Let G be a simple, connected graph and let A(G) the adjacency matrix of G. If D(G) is diagonal vertex degrees G, then for every real $$\alpha \in [0,1]$$ , $$A_{\alpha }(G)$$ defined as }(G) = \alpha + (1- ) A(G).$$ The eigenvalues form }$$ -spectrum $$G_1 {\dot{\vee }} G_2$$ {\underline{\vee \langle \text {v} \rangle {e} denote subdivision-vertex join, subdivision-edge R-vertex join R-edge two...

In fact, in the welding process, there are many problems that arise. Such as cracking caused by excessive stress Residual can result a decrease mechanical properties of material such brittle fracture, fatigue, and cracking. The purpose this study was to determine comparison tensile strength ASTM plate welded joints A36 with variations single vee butt bevel knowing effects ofpost-weldd heat trea...

Virtual execution environments (VEE) such as the Java Virtual Machine (JVM) and the Microsoft Common Language Runtime (CLR) have been designed when the dominant computer architecture featured a Von-Neumann interface to programs: a single processor hiding all the complexity of parallel computations inside its design. Programs are expressed in an intermediate form that is executed by the VEE that...

The notions of $${{\mathcal {N}}}$$ -ideal types $$(\in , \in )$$ and \! \vee \, {q})$$ soft $${\mathcal N}_{\in }$$ -set, {N}}}_{q}$$ {N}}}_{\in {q}}$$ -subalgebra in BCK/BCI-algebra are introduced, several properties investigated. Characterizations N}$$ discussed.

We unify several extensions of the classic Stone duality due to Grätzer, Hofmann–Lawson and Jung–Sünderhauf. Specifically, we show that $$\cup $$ -bases locally compact sober spaces are dual $$\prec -distributive $$\vee -predomains, where is a relation representing containment.

in order to study the effects of post – anthesis heat stress on source of six wheat genotypes (vee/nac, chamran, s79-10, dez, fong and kaveer), two separate field experiments were conducted as delayed as against optimum sowing dates in ahvaz coditions. plants in delayed sowing date experienced heat stress at post-anthesis growth stage. as study of grain yield indicated that the highest and the ...

Studies were made comparing the toxicity of beta-propiolactone (BPL) for mammalian (mouse) cells in vitro and for mice and for Venezuelan equine encephalomyelitis (VEE) virus which is highly cytopathogenic for each. The mammalian cells grown in tissue culture were found to be adversely affected by BPL in concentrations ranging from 0.001 to 0.1 mg/ml of supernatant fluid. The difference in resp...

in this paper, we firstly show that the $n$-dual operation of the right residual implication, which is induced by a left-conjunctive right arbitrary $vee$-distributive left semi-uninorm, is the right residual coimplication induced by its $n$-dual operation. as a dual result, the $n$-dual operation of the right residual coimplication, which is induced by a left-disjunctive right arbitrary $wedge...

Let G be a connected semisimple Lie group. There are two natural duality constructions that assign to G: its Langlands dual group $$G^\vee $$ , and Poisson–Lie $$G^*$$ respectively. The main result of this paper is the following relation between these objects: integral cone defined by cluster structure Berenstein–Kazhdan potential on double Bruhat cell $$G^{\vee ; w_0, e} \subset G^\vee isomorp...
