Vectorial capacity is a measure of the transmission potential of a vector borne pathogen within a susceptible population. Vector competence, a component of the vectorial capacity equation, is the ability of an arthropod to transmit an infectious agent following exposure to that agent. Comparisons of arbovirus strain-specific vector competence estimates have been used to support observed or hypo...

We construct exact duality transformations in pure SU(N) Hamiltonian lattice gauge theory ($2+1$) dimension. This is obtained by making a series of iterative canonical on the electric vector fields and their conjugate magnetic potentials four links around every plaquette. The resulting dual description terms scalar or plaquette flux loops potentials. Under they both transform like adjoint matte...

The general Lagrangian for maximal supergravity in five spacetime dimensions is presented with vector potentials in the 27 and tensor fields in the 27 representation of E6(6). This novel tensor-vector system is subject to an intricate set of gauge transformations, describing 3(27 − t) massless helicity degrees of freedom for the vector fields and 3t massive spin degrees of freedom for the tenso...

We use a two-photon dressing field to create an effective vector gauge potential for Bose-Einstein-condensed 87Rb atoms in the F=1 hyperfine ground state. These Raman-dressed states are spin and momentum superpositions, and we adiabatically load the atoms into the lowest energy dressed state. The effective Hamiltonian of these neutral atoms is like that of charged particles in a uniform magneti...

We recorded the vector magnetogastrogram (MGG) due to gastric electrical activity (GEA) in normal rabbits using a Superconducting QUantum Interference Device (SQUID) magnetometer and measured the degree of correlation of the MGG with 24 channels of serosal electrodes. The vector magnetometer allows us to non-invasively record three orthogonal magnetic field components and project the recorded m...

BACKGROUND/AIM To explore the therapeutic effects of thymidine kinase (TK) expressed by enhanced vector pGL3-basic- hTERTp-TK-EGFP-CMV driven by human telomerase reverse transcriptase promoter (hTERTp) as well as cytomegalovirus immediate early promoter enhancer (CMV). MATERIALS/METHODS Enhanced TK-EGFP expression was confirmed by fluorescent microscopy, real time PCR and telomerase activity....

We consider the scattering amplitude associated to a Schröodinger operator with a short range potential at an energy which is a non-degenerate maximum of the potential. We prove an asymptotic expansion of the semi-classical scattering amplitude in this setting. We compute the phase as well as the leading order symbol in this asymptotic expansion. Our work is motivated by earlier asymptotic deve...

Brain-computer interfaces (BCI) enable non-muscular powerful channel for communicating thanks to direct communication between the user’s brain and a computer. In this article, the presented BCI concerns the P300 speller which enables people to write a text on a computer by estimating P300 evoked potentials. In this work, an unsupervised algorithm is introduced for signal subspace estimation: th...

The Lie group adiabatic evolution determined by a Lie algebra parameter dependent Hamiltonian is considered. It is demonstrated that in the case when the parameter space of the Hamiltonian is a homogeneous Kähler manifold its fundamental Kähler potentials completely determine Berry geometrical phase factor. Explicit expressions for Berry vector potentials (Berry connections) and Berry curvature...

action potential models for toxin recognition JAMES PETERSON* and TAUFIQUAR KHAN Department of Mathematical Sciences, Clemson University, Clemson, SC, USA (Received 14 December 2005) In this paper, we present a robust methodology using mathematical pattern recognition schemes to detect and classify events in action potentials for recognizing toxins in biological cells.
