We show that each power bounded operator with spectral radius equal to one on a reflexive Banach space has a nonzero vector which is not supercyclic. Equivalently, the operator has a nontrivial closed invariant homogeneous subset. Moreover, the operator has a nontrivial closed invariant cone if 1 belongs to its spectrum. This generalizes the corresponding results for Hilbert space operators. Fo...

In this paper we consider the support properties of locally linearly independent re nable function vectors r T We propose an algorithm for computing the global support of the components of Further for T we investigate the supports especially the possibility of holes of re nable function vectors if local linear independence is assumed Finally we give some necessary conditions for local linear in...

Adenoviral vectors can be used to generate potent humoral and cellular immune responses to transgene products. Use of adenoviral vectors based on non-human isolates may allow for their utilization in populations harbouring neutralizing antibodies to common human serotypes. A vector chimera was constructed using simian adenovirus 22 (a serotype belonging to the species Human adenovirus E) and si...

  Toxoplasma gondii contain various immunogenic antigens. The most important Toxoplasma antigens are somatic and excreted/secreted antigens. Rhoptry proteins are known as excreted/secreted antigens. These antigens have been proposed as a vaccine candidate against toxoplasmosis. The main objective of the present work was cloning rhoptry protein1 (ROP1) Gene of Toxoplasma gondii (RH) in a cloning...

Abs t rac t -P roper t i e s of nonlinear multiobjective problems implied by the Karush-Kuhn-Tucker necessary conditions are investigated. It is shown that trajectories of Lagrange multipliers corresponding to the components of the vector cost function are orthogonal to the corresponding trajectories of vector deviations in the balance space (to the balance set for Pareto solutions). ~) 2003 El...

We use heavy vector meson SU~2!L3SU~2!R chiral perturbation theory to predict differential decay distributions for t→rpnt and t→K* pnt in the kinematic region where pV•pp/mV ~here V5r or K*! is much smaller than the chiral symmetry-breaking scale. We also predict the rate for t→vpnt in this region ~now V5v!. Comparing our prediction with experimental data, we determine one of the coupling const...

Let A be a real continuous nxn matrix on an interval T3 and let the n-vector x be a solution of the differential equation x = Ax on r. If [oc,g]er, g is called a conjugate point of a if the equation has a nontrivial solution vector x = (x1,...,xn) such that x1(a) = ... = xk(a) = x k+1(P) = ... = x (0) = 0 for some ke[l,n-l]. It is shown that the absence on (t..,t ) of a point conjugate to t, wi...

Here u, b describe the flow velocity vector and the magnetic field vector respectively, p is a scalar pressure, ν > 0 is the kinematic viscosity and η > 0 is the magnetic diffusivity, while u0 and b0 are the given initial velocity and initial magnetic field respectively, with ∇ · u0 = ∇ · b0 = 0. If ν = η = 0, (1.1) is called the ideal MHD equations. Using the standard energy method, it can be ...

T HERE is some evidence1' 2 that the spatial angle between the mean QRS and T vector might serve as an important criterion for the diagnosis of ventricular hypertrophy or coronary insufficiency, although the angle was not actually measured. Recently, a method has been described' to construct and measure this angle from the conventional electrocardiogram. With this method, a vector is defined in...

Let T : M → M be an invertible measurable transformation, and μ be a T -invariant probability on M . Let π : E → M be a finite-dimensional real vector bundle over M , endowed with a measurable Riemannian metric ‖ · ‖. Let F : E → E be a measurable vector bundle automorphism over T : this means that π ◦ F = T ◦ π and the action Fx : Ex → ET (x) of F on each fiber Ex = π−1(x) is a linear isomorph...
