The tumors in 249 patients presenting initially with stages Ta and T1 bladder cancer were analyzed for tumor progression and recurrence. Only transurethral resection and/or fulguration was used before the first recurrence. Patients who received intravesical chemotherapy after the first tumor recurrence were excluded from an analysis of progression.(More)
With multiple air-interface support capabilities and higher cell densities, future cellular networks will offer a diverse spectrum of user services. The resulting dynamics in traffic load and resource demand will challenge present control loop algorithms. In addition, frequent upgrades in the network infrastructure will substantially increase the network(More)
This article presents and analyzes a technique for reducing the spurious signal content in digital sinusoid synthesis. Spurious-harmonic (spur) reduction is accomplished through dithering both amplitude and phase values prior to word-length reduction. The analytical approach developed for analog quantization is used to produce new bounds on spur performance(More)
Urinary cytology is almost as accurate as cystoscopy in appraising the presence or absence of visible tumor. Falsely negative results are virtually limited to low stage, low grade tumors. Urinary cytology often provides information about the neoplastic state of the epithelium not provided by cystoscopic examination. Cytology has become practical and simple(More)
1. Instrumentation and technique for microsurgical reconstruction of small arteries are described. 2. Two cases are reported in each of which an obstruction was removed from the middle cerebral artery for early hemiplegia. 3. The work presented is of a preliminary nature. No conclusions can be drawn as to ultimate value. Further clinical trial seems(More)
ABH tissue isoantigens were measured by the Specific Red Cell Adherence (SRCA) test in 66 surgical specimens of urinary bladder, including 53 transitional cell carcinomas, 2 squamous cell carcinomas and 11 controls. The SRCA test was strongly positive in 10 of 11 controls. ABH isoantigens were absent or equivocally present in 68 percent of noninvasive(More)
