Avian Flu in Ferrets A recent outbreak of avian H7N9 influenza humans eastern China has been closely monitored for any evidence human-to-human transmission and its potential sparking a pandemic. Zhu et al. (p. 183 , published online 23 May) examined the behavior virus ferret, mammalian model human influenza. The was excreted by ferrets could be transmitted readily contact but displayed limited capacity airborne infectivity. pathology is similar to H1N1, it seems that factors other than...
ABSTRACT We characterized the A/Shanghai/1/2013 virus isolated from first confirmed human case of A/H7N9 disease in China. The isolate contained a mixed population R (65%; 15/23 clones) and K (35%; 8/23 at neuraminidase (NA) residue 292, as determined by clonal sequencing. with R/K 292 exhibited phenotype that is sensitive to zanamivir oseltamivir carboxylate enzyme-based NA inhibition assay. plaque-purified dominant K292 (94%; 15/16 showed sensitivity had decreased >30-fold >100-fold...
An average linear finite difference scheme for the numerical solution of initial-boundary value problem Generalized Rosenau-KdV equation is proposed. The existence, uniqueness, and conservation energy are proved by discrete norm method. It shown that 2nd-order convergent unconditionally stable. Numerical experiments verify theoretical results right method efficient reliable.

A collocation Fourier scheme for Swift-Hohenberg equation based on the convex splitting idea is implemented. To ensure an efficient numerical computation, we propose a general framework with linear iteration algorithm to solve non-linear coupled equations which arise semi-implicit scheme.

We analyze a first order in time Fourier pseudospectral scheme for Swift-Hohenberg equation. One major challenge the higher diffusion non-linear systems is how to ensure unconditional energy stability and we propose an efficient equation based on convex splitting of energy. The?oretically, proved. Moreover, following derived aliasing error estimate, convergence analysis discrete l2-norm proposed given.
Because of the isotropic energy band structure Γ electrons in N type GaAs/AlGaAs quantum well infrared photodetector (QWIP), normal incident radiation absorption is impossible so that optical grating becomes key requirements for such QWIPs. The development very long wavelength GaAs/Al<sub>x</sub>Ga<sub>1-x</sub>As Infrared photodetectors (QWIPs) proposed paper based on optimization 2-d period design, processing detector, and a 16μm cutoff QWIP has been demonstrated at 40K. blackbody...
We present a variant of second order accurate in time backward differentiation formula schemes for the Cahn-Hilliard equation, with Fourier collocation spectral approximation space.
