—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)
A 31-year-old male visited our hospital with a complaint of left scrotal pain that began suddenly one week before the visit. The results of scrotal examination, blood cell count and biochemical examination were normal. Enhanced magnetic resonance imaging (MRI) showed a well-defined avascular lesion of the left testis with rim enhancement. With the suspicion(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)
Conventional linear instantaneous mixing model becomes unsuitable if propagation time delays are taken into account. A blind separation algorithm based on second-order Taylor approximation for delayed sources (SOTADS) is presented, under the constraint that time delays are small in comparison with the coherence time of each source. Simulation results(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)
