By implementing a field-programmable gate array (FPGA)-based simulator, we investigate the performance of randomly constructed high-rate quasi-cyclic (QC) low-density parity-check (LDPC) codes for the magnetic recording channel at very low block sector error rates. On the basis of extensive simulations, we conjecture guidelines for designing randomly(More)
OBJECTIVE To examine 10 cases with primary cutaneous CD30-positive anaplastic large cell lymphoma (ALCL), analyze their clinical manifestations and pathological and immunohistochemical features, and improve early diagnosis of this disease. METHODS We studied the morphological characteristics of primary cutaneous CD30-positive ALCL using histopathological(More)
Facing the condition that misdiagnoses of breast tumor recognition are easily caused while using fine needle aspiration cytology, this paper proposes a method of breast tumor auxiliary diagnosis based on Probabilistic Neural Network (PNN) classifier optimized by Principal Component Analysis (PCA) and Particle Swarm Optimization (PSO). The main(More)
This study aims to investigate corticofugal modulation on spontaneous activities of the external nucleus of the inferior colliculus (ICx) in a salicylate acid (SA) induced tinnitus rat model by the stimulation of the primary auditory cortex (AI). Extracellular recording techniques and stereotaxic method were used. The spontaneous activities of a single unit(More)
Melittin liposomes surface modified with poloxamer 188 were developed, and the effect of poloxamer 188 was investigated with regard to anti-cancer effect and vascular stimulation. Melittin liposomes surface modified with poloxamer 188 at different concentrations (0%, 2%, and 5%) were prepared using the adsorption method, followed by in vitro(More)
