Two-Time physics applies broadly to the formulation of physics and correctly describes the physical world as we know it. Recently it was applied to a 2T reformulation of the d = 4 twistor superstring, which was suggested by Witten as an efficient approach for computations of physical processes in the maximally supersymmetric N = 4 Yang-Mills field theory in four dimensions. The 2T formalism pro...

A new subclass of Hadamard full propelinear codes is introduced in this article. We define the HFP(2t, 2, 2)-codes as codes with a group structure isomorphic to C2t × C 2 2 . Concepts such as rank and dimension of the kernel are studied, and bounds for them are established. For t odd, r = 4t−1 and k = 1. For t even, r ≤ 2t and k 6= 2, and r = 2t if and only if t 6≡ 0 (mod 4).

Let G = (V,E) be a connected graph (or hypergraph) and let d(x, y) denote the distance between vertices x, y ∈ V (G). A subset W ⊆ V (G) is called a resolving set for G if for every pair of distinct vertices x, y ∈ V (G), there is w ∈ W such that d(x,w) 6= d(y, w). The minimum cardinality of a resolving set for G is called the metric dimension of G, denoted by β(G). The circulant graph Cn(1, 2,...

BACKGROUND Lopinavir/Ritonavir (Kaletra®) is a protease inhibitor used in the management of HIV infection. The increased incidence of toxicity of antiretroviral therapy (ART) has necessitated proper evaluation of their effects on reproductive health. PURPOSE Therefore, this study was designed to investigate the effects of Kaletra® on male reproductive system in Wistar rat. METHODS Eighteen ...

Coexistence phenomenon refers to the absence of expected tongues of instability in parametrically excited systems. In this paper we obtain sufficient conditions for coexistence to occur in the generalized Ince equation: (1 + a1 cos t+ a2 cos 2t) v̈ +(b1 sin t+ b2 sin 2t) v̇ +(δ + c1 cos t+ c2 cos 2t) v = 0 The results are applied to the stability of motion of a nonlinear normal mode, the x-mode, ...

This paper proposes a new design of 2T AND gate. Performance comparison of proposed gate with existing 2T GDI technique is presented. Different methods have been compared with respect to the number of devices, power consumption, power-delay product, temperature sustainability and noise immunity in order to prove the superiority of proposed design over existing 2T gate design. The simulation has...

A novel alkaliphilic spore-forming bacterium was isolated from the benthic sediments of the highly mineralized steppe Lake Khilganta (Transbaikal Region, Russia). Cells of the strain, designated Х-07-2T, were straight to slightly curved rods, Gram-stain-positive and motile. Strain Х-07-2T grew in the pH range from 7.0 to 10.7 (optimum pH 9.6-10.3). Growth was observed at 25-47 °C (optimum 30 °C...
