Background Reg IV is a member of the regenerating gene family and has been demonstrated to be overexpressed in gastric cancer. However, the functional mechanism of Reg IV in gastric cancer is still unclear. Methods Expression of Reg IV and SOX9 were investigated by immunohistochemistry (IHC) and real-time PCR, and the correlation between the expression of Reg IV and SOX9 was analyzed in gastric...
The purpose of this study was to explore the relationship between grip strength and inter-muscular coordination of the forearms and hands. Twenty-four healthy young volunteers participated in the experiment. The subjects were instructed to grip hydraulic hand dynamometer with five force levels-maximal voluntary contraction (MVC), 70% MVC, 50% MVC, 30% MVC and without any contraction. Muscle activity...
The modularization strategy can dramatically shorten the lead time and reduce the cost of complex products development, and module partition is the basis of the modularization. In this paper, a complex network module is built to represent the complex product structure, and using interval-valued intuitionistic fuzzy sets to calculate the weights of the edges of the network model are brought to illustrate...
In this paper, a method to detect joint time-frequency offset is proposed based on the linear canonical transform. According to the fundamental properties of this transform, a parametric correlation is introduced, which can be regarded as the generalization of methods based on correlation and other transforms. Besides, its maximum can be identified with a line structure in the time-frequency plane...
Satellite signal acquisition is indispensable for signal tracking and solution, and its operating time directly determines the starting speed of the software receiver. The length of Beidou code is twice of Global Positioning System (GPS) C/A code. Therefore, the acquisition time will increase with the traditional algorithm. This paper proposed a fast acquisition algorithm which decomposed the N points...
As a 3D video extension of Audio Video Coding Standard (AVS), 3D-AVS is being developed to improve the coding efficiency of multi-view video. Since multi-view video is composed of projections of the same scenery from different viewpoints at the same time instant, it contains a large amount of inter-view redundancies. To exploit the inter-view correlation, this paper presents a method to derive the...
Using the data of Chinese listed firms on main board in the year of 2008, this paper investigates the explanatory power to market value added (MVA) of economic value added (EVA) and traditional accounting measures, respectively. The empirical results show that there are significant correlations between EVA and most of the accounting performance measures, such as earnings per share, net profit and...
Institutional investors impacting the capital structure of listed companies is an indisputable fact. However, previous studies using the linear method come to different conclusions. In this paper, using the 2006-2008 A-share listed data of China we find that: in current and lagged one year, the relationship between institutional ownership and capital structure of listed companies are non-linear and...
A set of solutions for vehicle tracking module of intelligent transportation system is proposed. A vehicle tracking system based on color histogram distance and binary information is implemented. The System solves camera calibration, vehicle moving prediction, vehicle tracking and other issues. Three experiment under different scenarios results that the accuracy of the vehicle identification up to...
According to the fact that heating will affect the image collection, target identification and track, so it will affect the alignment precision of the chips and substrates in the process of chips package. Sequence images were collected through the thermosonic flip-chip bonder under the different heating temperature, their parameters distribute regulation of translation, scale ,rotation under the influence...
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
