Let NDTIME(f(n),g(n)) denote the class of problems solvable in O(g(n)) time by a multi-tape Turing machine using an f(n)-bit non-deterministic oracle, and let DTIME(g(n)) = NDTIME(0, g(n)). We show that if all-pairs shortest paths problem (APSP) for directed graphs with N vertices integer edge weights within super-exponential range { −2Nk+o(1),....,2Nk+o(1) }, k≥1 does not admit truly subcubic ...

objective(s): this study was performed to investigate the effects of mucosal acidification on mrna expression and protein synthesis of cystathionine gamma lyase (cse), cystathionine beta synthase (cbs), and mucosal release of h2s in gastric mucosa in rats. materials and methods:thirty-two rats were randomly assigned into 4 groups (8 in each), including: the control group, hcl (10 mm) treated gr...

Glucagon-like peptide-1 receptors are widely expressed in the brain and its association with nitric oxide is suggestive ofits role epilepsy. In this study, we investigated effects of exenatide, a glucagon-like receptor agonist, on theepileptiform activity induced by penicillin injection. The study used 72 male Wistar albino rats 9 groups. All groupsexcept last group which received only intracor...

This paper investigates the class of rings in which every nn-absorbing ideal is a prime ideal, called nn-AB ring, where nn positive integer. We give characterization an ring. Next, for ring RR, we study concept Ω(R)={ωR(I);I proper R},Ω(R)={ωR(I);I R}, ωR(I)=min{n;I n-absorbing R}ωR(I)=min{n;I R}. show that if RR Artinian or Prüfer domain, then Ω(R)∩NΩ(R)∩N does not have any gaps (i.e., wheneve...

Abstract The ITER Poloidal Field (PF) coils are wound into double pancakes with NbTi cable-in-conduit conductors, which connected by joints in shaking hands lap-type configuration. operating pulsed mode a maximum current of 55 kA and peak magnetic field 6.4 T, utilizing electromagnetic load on the conductors joints. A series PF qualification joint samples modified praying configuration is measu...
