Let x = (x1, . . . , xn) denote a point in R , and dx = dx1 dx2 · · · dxn denote the volume element in R . Let u(x, t) : G → R be a time-dependent vector field defined on an open subset Ĝ of x-t-space with components ui, i = 1, . . . , n. G will be called a domain for brevity, though we do not assume that Ĝ is connected. Domains in x-space will be denoted G, in x-t-space they will be denoted Ĝ....
A generalized formalism of QCD multipole expansion including constituent quark field quantization is proposed. It can be applied to study soft-gluon emission processes of heavy quark-antiquark systems with quark flavor changing or quark pair annihilation. As an application, the radiative decays J/t+h + 7 + 77 and J/t) --t 7+7r” are studied in this framework. It is shown that J/$ + 7+~ is domina...
Most readers will already have encountered at least one ODE model of disease transmission. Here we briefly review the construction of such models and some of their predictions. For an in-depth review of these models the reader may want to consult the survey article [1]. All ODE models of disease transmission are continuous-time compartment-level models. Here we focus on models of type SI, SIS, ...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

BACKGROUND & OBJECTIVE Vector control, using agents of chemical origin, continues to be practiced in the control of vector borne diseases. However, due to some drawbacks including lack of selectivity, environmental contamination, and emergence and spread of vector resistance, development of natural products for vector control has been a priority in this area. In the present study we evaluated t...
The cross section for elastic vector meson production in photon-proton interactions at large t is considered using the exact analytic solution of the BFKL equation in the azimuthally symmetric n = 0 limit. We use a non-relativistic model for the vector meson production and find a small shrinkage in the t-distribution with increasing energy.
Using the resonance chiral theory Lagrangian, we perform a calculation of the vector and axial-vector two-point functions at the next-to-leading order (NLO) in the 1/NC expansion. We have analyzed these correlators within the singleresonance approximation and have also investigated the corrections induced by a second multiplet of vector and axial-vector resonance states. Imposing the correct QC...

Here we describe a novel vaccine vector for expressing human immunodeficiency virus (HIV) antigens. We show that recombinant attenuated yellow fever vaccine virus 17D expressing simian immunodeficiency virus SIVmac239 Gag sequences can be used as a vector to generate SIV-specific CD8(+) T-cell responses in the rhesus macaque. Priming with recombinant BCG expressing SIV antigens increased the fr...
