We consider the development and analysis of local discontinuous Galerkin methods for fractional diffusion problems in one space dimension, characterized by having fractional derivatives, parameterized by β ∈ [1, 2]. After demonstrating that a classic approach fails to deliver optimal order of convergence, we introduce a modified local numerical flux which(More)
A novel three-hop cooperative diversity system model is proposed in this paper comparing to conventional dual-hop cooperative systems, assuming all terminals have only one antenna for size limitation. This system model avoids complex relay selection criterions and data forwarding strategies which are necessary for conventional cooperative systems to(More)
Five antibiotics compounds, tetracycline (TC), oxytetracycline (OTC), doxycycline (DOC), chlortetracycline (CTC) and chloramphenicol (CP), were successfully separated and determined by high performance capillary electrophoresis(HPCE). Effects of buffer pH, various organic additives and temperature on electrophoretic separation of antibiotics were(More)
Wireless relays extend coverage, improve spectral efficiency, and enhance reliability and rates of wireless communication systems. In this work, we introduce a three-hop cooperative system model comparing to conventional dual-hop cooperative systems, assuming all terminals can only share a part of power for cooperation and have only one antenna for size(More)
To apply space time block coding(STBC) in a cooperative way, a novel three-hop cooperative system model is proposed in this paper comparing to conventional dual-hop cooperative systems, assuming all terminals have only one antenna for size limitation. Both source node and destination node request free nodes around them to perform as virtual antennas based(More)
Acutohaemolysin, a phospholipase A(2) (PLA(2)) from the venom of the snake Agkistrodon acutus, has been isolated and purified to homogeneity by anion-exchange chromatography on a DEAE-Sepharose column followed by cation-exchange chromatography on a CM-Sepharose column. It is an alkaline protein with an isoelectric point of 10.5 and is comprised of a single(More)
Abstract. The traditional wave equation models wave propagation in an ideal conducting medium. For characterizing the wave propagation in inhomogeneous media with frequency dependent power-law attenuation, the spacetime fractional wave equation appears; further incorporating the additive white Gaussian noise coming from many natural sources leads to the(More)
OBJECTIVE To study the distribution characteristics of lactobacillus in the vaginal mucosa of patients with HPV infection. METHODS The planting density of lactobacillus in vaginal secretions of 95 cases with HPV16/18 infection and 90 cases of normal women of childbearing age were observed by oil microscope. And the strains of vaginal lactobacilli in two(More)
