Conceptualization and Experimental Verification of a 50 kW 600 V/4 kV/600 V DC Power Supply System for Ultra-Deep-Sea HyDrones

open access: yesIEEE Access
Remotely operated underwater vehicles (ROVs) are crucially important in deep-sea exploration. Today, ROVs are typically supplied from a surface vessel via a medium-voltage (MV) 50 Hz/60 Hz ac umbilical.

Intraoperative Evaluation of Bladder Perfusion Using Indocyanine Green Fluorescence Imaging During Total Pelvic Exenteration After Interruption of Blood Flow From the Internal Iliac Vessels

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Intraoperative ICG fluorescence imaging demonstrated that bladder perfusion was maintained through blood flow from the pubic side, even after complete division of the internal iliac vessels during total pelvic exenteration. ABSTRACT Background In lateral lymph node dissection (LLND) for locally advanced or recurrent rectal cancer, concomitant resection
