We have developed a novel baculovirus surface display(BVSD)system for the isolation of membrane *** expressed a reporter gene that encoded HA fused in frame with the signal peptide and transmembrane domain of the baculovirus gp64 protein which is displayed on the surface of BmNPV *** expression of this fusion protein on the virion envelope allowed us to develop two methods for isolating membrane *** the first method,we isolated proteins directly from the envelope of budding BmNPV *** the second method,we isolated proteins from cellular membranes that had disintegrated due to viral *** isolated a total of 6,756 *** these,1,883 have sequence similarities to membrane proteins;1,550 proteins are homologous to known membrane *** study indicates that membrane proteins can be effectively isolated using our BVSD *** an analogous method,membrane proteins can be isolated from other eukaryotic organisms,including human beings,by employing a host cell-specific budding virus.

This paper presents an algorithm for automatically generating in-between frames of two artistic brushstrokes. The basic idea of the algorithm is to represent the two key frames of artistic brushstrokes in disk B-spline curves, and then make blending of their geometric intrinsic variables. Given two key frames of artistic brushstrokes, the skeleton curves can be obtained by certain skeleton-based techniques. After disk B-spline representation of the key frames is generated, interpolation of the intrinsic variables of the initial and the target disk B-spline curves is carried out. Examples show that this method can efficiently create in-between frames of artistic brushstrokes.

This article developed a decomposition model of energy productivity on the basis of the economic growth model. Four factors were considered which may influence China’s energy productivity according to this model: technology improvement, resource allocation structure, industrial structure and institute arrangement. Then, an econometric model was employed to test the four factors empirically on the basis of China’s statistical data from 1978 to 2004. Results indicated that capital deepening con- tributes the most (207%) to energy efficiency improvement, and impact from labor forces (13%) is the weakest one in resource factor; industrial structure (7%) and institute innovation (9.5%) positively improve the energy productivity.

Multimedia content analysis and management are a promising and challenging *** this paper we develop a novel approach to image representation,which we call group sparse representation (GSR),for image classification and video *** basic idea is to represent a test image as a weighted combination of all the training *** particular,we introduce two sets of weight coefficients,one for each training image and the other for each ***,we formulate our concern as a group nonnegative garrote *** resulting representations are sparse,and they are appropriate for discriminant *** on Caltech101 and PASCAL VOC2008 image dataset and TRECVID2005 video corpus testify that our proposed approach is efficient and effective.
