An electro-optically tunable vertically integrated As<sub>2</sub>S<sub>3</sub> Mach-Zehnder interferometer side coupled to a Ti-diffused waveguide on LiNbO<sub>3</sub> substrate was designed and fabricated. Asymmetric coplanar strip electrodes were placed along the As<sub>2</sub>S<sub>3</sub> path, which show strong electro-optic tuning capability, shifting(More)
A vertically integrated As<sub>2</sub>S<sub>3</sub> Mach-Zehnder interferometer side-coupled to a Ti:LiNbO<sub>3</sub> waveguide is electro-optically tuned utilizing asymmetric coplanar strip electrodes along the chalcogenide path. Tuning of the TM polarization is demonstrated with V<sub>&#x03C0;</sub> = 19.6 V.
To evaluate benefits of sentinel lymph node (SLN) biopsy for staging accuracy in prostate cancer. Extended pelvic lymph node dissection (ePLND) is a preferred staging tool; however, it may underestimate the incidence of nodal involvement. Eighty patients with estimated risk of lymphadenopathy above 5 % based on Briganti nomogram had Tc-99m-labeled(More)
Salvage lymph node dissection is a therapeutic option in patients with nodal-only recurrence after radical prostatectomy. Although this operation does not achieve a complete cure in the majority of cases, it can prolong survival and help postpone hormonal therapy in selected patients while being a relatively safe procedure. The authors describe a case study(More)
OBJECTIVE The authors previously successfully applied the "flap-and-trough" (FT) method of antireflux ureterointestinal anastomosis (UIA) in a pilot set of 81 patients. This randomized prospective trial tested the effectiveness of this method in protecting the upper urinary tract from obstruction, reflux and infections. MATERIAL AND METHODS Forty-nine(More)
This case report describes a rare case of adenocarcinoma of the epididymis and the role of locoregional surgery in the therapeutic algorithm. We report a case of primary adenocarcinoma of the epididymis in a 61-year-old man who was primarily examined for nodular enlargement of the head of the epididymis. Retroperitoneal lymphadenectomy which the patient(More)
