The local binary pattern (LBP) and its variants have shown their effectiveness in texture images representation. However, most of these LBP methods only focus on the histogram of LBP patterns, ignoring the spatial contextual information among them. In this paper, a uniform three-structure descriptor method was proposed by using three different encoding methods so as to obtain the local spatial contextual...
The system structure of Phase-Inversion Symmetric- Spread Spectrum Communication (PIS-SSC) is introduced, anti-interference abilities of the traditional spread spectrum communication (SSC) system and Phase-Inversion Symmetric- Spread Spectrum Communication system (PIS-SSC) are analyzed. The MATLAB/Simulink simulation models of PISM, SSC system, PIS-SSC system and narrowband interference are constructed,...
Interleukin (IL) 4 is a type 2 cytokine which has a negative immunoregulatory role in human infection. IL-4 suppresses the production of interferon-γ and enhances IL-10 synthesis. However, the effect of IL-4 on proliferative response of lymphocytes remains to be elucidated. We have previously reported an increase in production of IL-4 in subjects with Helicobacter pylori (H. pylori) infection....
