—This paper addresses the problem of blind source separation (BSS) of n independent sources from their m linear mixtures in the over-determined cases (m n >) with unknown and dynamically changing number of sources. The system architecture including an on-line source number estimator and an auto-adjust separation mechanism is considered based on the(More)
Urethral leiomyoma is an extremely rare condition that arises from the smooth muscle of the urethra. To the best of our knowledge, there is only a single reported recurrence treated by a repeat excision in the literature to date. The present study reports an exceptionally rare case of a recurrent huge leiomyoma of the female urethra. The 47-year-old female(More)
CAR is a transmembrane protein that is expressed in various epithelial and endothelial cells. CAR mediates adenoviral infection, as well as adenovirus-mediated oncolysis of AxdAdB-3, an E1A/E1B double-restricted oncolytic adenovirus, in prostate cancer cells. This study further assessed the therapeutic efficacy of AxdAdB-3 with Arg-Gly-Asp (RGD)-fiber(More)
OBJECTIVE To study the types and emergence time of YMDD motif mutation in hepatitis B virus (HBV) polymerase gene during lamivudine treatment. METHODS The serum samples were collected from 33 patients with HBV DNA rebounding and 2 non-responders after at least one year lamivudine treatment. HBV polymerase gene was amplificated by PCR, then the products(More)
OBJECTIVE To investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision. METHODS We retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent(More)
OBJECTIVE To report the amelioration of the three-piece inflatable penile prosthesis (IPP) implantation and the prevention of its complications. METHODS Thirty-two patients with moderate to severe erectile dysfunction (ED) irresponsive to conservative treatments received the implantation of the three-piece IPP. The surgical techniques were ameliorated in(More)
To solve the underdetermined blind separation (UBSS) problem, Aissa-El-Bey et al. have proposed the significant subspace-based algorithms in the time-frequency (TF) domain, where a fixed (maximum) value of K, i.e., the number of active sources overlapping at any TF point, is considered for simplicity. In this paper, based on the principle component analysis(More)
Relevant data including diagnosis and treatment model, operation situation, etc. are analyzed in our wound care center and compared with abroad based-on literature retrieval, to find out a suitable way for setting up wound care centers in our country. Wound care center with mode of multidisciplinary cooperation that is "specialist-oriented" was established(More)
