In this paper, exact solutions of the generalized Boussinesq-like B(m, n) equation with nonlinear dispersion u(tt) + a(u(n))(xx) + b(u(m))(xxxx) = 0, m, n E R are investigated. As a result, under different parameter conditions, abundant compactons, peakons and solitary solutions, which include not only some known results but also some new ones, are obtained. The approach we used is simple and also suitable for studying the traveling wave solutions of some other equations. (c) 2006 Elsevier Ltd. All rights reserved.

In this paper, we employ the bifurcation theory of planar dynamical systems to study the smooth and nonsmooth traveling wave solutions of the generalized Degasperis-Procesi equation ut - u(xxt) + 4u(m)u(x) = 3u(x)u(xx) + uu(xxx). The parameter condition under which peakons, compactons and periodic cusp wave solutions exist is given. The numerical simulation results show the consistence with the theoretical analysis at the same time. (C) 2006 Elsevier B.V. All rights reserved.

Block adjustment process, based on a multisensor block adjustment, is applied to VIR and SAR images: SPOT-5 HRG and RADARSAT SGF. The affine transformation in the image plane and the RPC (Rational Polynomial Coefficients or Rapid Positioning Capability) model and algorithms were used for the processing. Preliminary results of block formed with all images gave positional errors of around 20-26 m, these errors also include the 1:50,000 map errors (25-30 m).

The rational polynomial camera (RPC) model is a generalized sensor model that is capable of achieving high approximation accuracy. Unfortunately, in almost all previous literature, the estimator of the parameters of the RPC model is biased, and the RPC model is not for SAR Imagery. In this paper, an unbiased RPC estimator is presented. Based on numerous tests, the following conclusion can be drawn. The RPC model is suited not only for push-broom imagery but also for SAR imagery.

The potency of CD8(+) cytotoxic T lymphocyte (CTL) responses toward core antigen has been shown to affect the outcomes of hepatitis B virus (HBV) infection. Since single-chain trimers (SCT) composed of peptide epitope beta(2)-microglobulin (beta(2)m) and major histocompatiblity complex (MHC) class I heavy chain covalently linked together in a single molecule have been shown to stimulate efficient CTL responses, we investigated the properties of human leucocyte antigen (HLA)-A2 SCTs encoding the HBV core antigen (HBcAg) epitopes C18-27 and C107-115. Transfection of NIH-3T3 cells with pcDNA3.0-SCT-C18-27 and SCT-C107-115 leads to stable presentation of HBcAg epitopes at the cell surface. HLA-A2.1/Kb transgenic mice vaccinated with the SCT constructs, either as a DNA vaccine alone or followed by a boost with recombinant vaccinia virus, were shown to generate HBcAg-specific CTL responses by enzyme-linked immunospot assay (ELISPOT) and in vitro interferon-gamma release experiments. HBcAg-specific CTLs from vaccinated HLA-A2.1/Kb transgenic mice were able to inhibit HBV surface and e antigen expression as indicated by HepG2.2.15 cells. Our data indicate that a DNA vaccine encoding a human HLA-A2 SCT with HBV epitopes can lead to stable, enhanced HBV core antigen presentation, and may be useful for the control of HBV infection in HLA-A2-positive HBV carriers.
