The 3-metric gij and extrinsic curvature (second fundamental form) Kij are the fundamental variables describing the geometry in any space+time decomposition of the Einstein equations. (g,K) describe the local geometry of a single space-like hypersurface M , and it is then natural to describe the evolution of the space-time geometry by a 1-parameter family (g(t), K(t)), describing the local geom...

brucellosis is a debilitative disease that imposes costs on both economy and society. it is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. in iran, brucella melitensis is a common causative agent for brucellosis and bp26 protein of this bacterium having a good antigenesity and an important vaccine candidate. in this study b. meli...

Let V and W be two real vector spaces and let &sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of &sim if Tx &sim Ty whenever x &sim y (respectively Tx &sim Ty if and only if x &sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate an...

1. Introduction. Let J be a closed linear interval ao^tSfo. Let r(/) = (#(/), y(t) } z(t)), tSI, represent a vector function whose three components x(t), y(i) t z(t) are of bounded variation and continuous on I. This vector function determines in Euclidean 3-space a curve x~x{t), y~y(t), z=*z(t) whose length we denote by LQç). By convergence in length of a sequence of such vector functions $ n ...

objective: development of high producing mammalian cell lines is a major bottleneck in manufacturing of recombinant therapeutic proteins. this study examines the effect of using the matrix attachment region from the human interferon beta gene in combination with promoter activation strategy with e1a 13s protein on human tissue plasminogen activator (t-pa) expression in chinese hamster ovary (ch...

We present a vector space version of Katona’s t-intersection theorem [11]. Let V be the n-dimensional vector space over GF(q), and let F be a family of subspaces of V . Suppose that dim(F ∩F ′) ≥ t holds for all F,F ′ ∈ F . Then we show that |F | ≤ ∑k=d [n k ] for n+t = 2d, and |F | ≤ ∑k=d+1 [n k ] + [n−1 d ] for n+t = 2d+1. We also consider the case when the condition dim(F ∩F ′) ≥ t is replac...

From a studyof 2.7 million J/I/J decays with the MARK III detector at SPEAR, we determine branching ratios for decays of the Q to q?r+~-, x*KrKs, T+T-T+T-, ?r+r-K+K-, pp, the previously unobserved modes q’?r+x-, I~OK+K-, K*qfg+, K*q*O, and new upper limits on pp, ww, 6~, A2 T, ~T,J and r]KK. When combined, the different measurements of the qc mass yield (2980.2 f 1.6) MeV/c2. In the decays Q + ...

In this Supplementary Appendix we present additional new material related to the main paper “Generalized Autoregressive Score Models with Applications”. We refer to the model as the GAS model. For reference purposes, we first give a short review of the relevant equations for the general GAS model. Appendix A presents more existing models that can be represented as special cases of GAS models. A...

Let $T$ be a bounded operator on the Banach space $X$ and $ph$ be an analytic self-map of the unit disk $Bbb{D}$‎. ‎We investigate some operator theoretic properties of‎ ‎bilateral composition operator $C_{ph‎, ‎T}‎: ‎f ri T circ f circ ph$ on the vector-valued Hardy space $H^p(X)$ for $1 leq p leq‎ ‎+infty$.‎ ‎Compactness and weak compactness of $C_{ph‎, ‎T}$ on $H^p(X)$‎ ‎are characterized an...
