Given a null geodesic γ0(λ) with a point r in (p, q) conjugate to p along γ0(λ) , there will be a variation of γ0(λ) which will give a time-like curve from p to q. This is a well-known theory proved in the famous book[3]. In the paper we prove that the timelike curves coming from the above-mentioned variation have a proper acceleration which approaches infinity as the time-like curve approaches...

For a point of the projective space \(\text {PG}(n,q)\), its Redei factor is linear polynomial in \(n+1\) variables, whose coefficients are coordinates. The power sum subset S {PG}(n,q)\) \((q-1)\)-th powers factors points S. fact that many subsets may share same offers natural connection to discrete tomography. In this paper we deal with two-dimensional case and show notion ghost, employment e...

A null manifold is a differentiable M endowed with degenerate metric tensor g. In this work we provide sufficient conditions for to be isometrically immersed as hypersurface into simple connected semi-Riemannian of constant sectional curvature c and index q

human serum paraoxonase (hupon1:   ec 3.1.8.1), a calcium-dependent esterase, is synthesized in the liver and   widely distributed in tissues including liver, kidney, intestine, and serum,   where it is associated exclusively with high-density lipoprotein.  human paraoxonase-1 plays an important role   in prevention of atherosclerosis and also protection against organophosphate-induced   neurot...

Summary: Qvality is a C++ program for estimating two types of standard statistical confidence measures: the q-value, which is an analog of the p-value that incorporates multiple testing correction, and the posterior error probability (PEP, also known as the local false discovery rate), which corresponds to the probability that a given observation is drawn from the null distribution. In computin...

this study considers a two echelon supply chain system consisting of one manufacturer and one retailer. under vendor managed inventory (vmi) program, the manufacturer is authorized to manage inventories of agreed upon stock keeping units at retail's locations. in this paper, we assume that the manufacturer monitors inventory levels at retailer's location, replenishes her stock under (...
