Analysis of Channel Area Fluctuation Effects of Gate-All-Around Tunnel Field-Effect Transistor.

In this manuscript, channel area fluctuation (CAF) effects on turn-on voltage () and subthreshold swing (SS) in gate-all-around (GAA) nanowire (NW) tunnel field-effect transistor (TFET) with multi-bridge-channel (MBC) have been investigated for the first time. These variations occur because oblique etching slope makes various elliptical-shaped channels in MBC-TFET. Since TFET is promising candidates to succeed metal-oxide-semiconductor FETs (MOSFET), these variation effects have been compared to MOSFET.

Can unilateral-approach minimally invasive transforaminal lumbar interbody fusion attain indirect contralateral decompression? A preliminary report of 66 MRI analysis.

Purpose: Few studies have measured the amount of indirect decompression at the contralateral neural foramen after unilateral-approach minimally invasive transforaminal lumbar interbody fusion (MITLIF). This study examined the amount of intraoperative indirect decompression at the contralateral neural foramen after a unilateral-approach MITLIF in patients with bilateral foraminal stenosis.

Methods: From February 2009 to October 2012, 66 consecutive patients with bilateral foraminal stenosis underwent unilateral-approach MITLIF and postoperative magnetic resonance imaging (MRI).

Increased size of a gas-filled intradural cyst causing acute foot drop: a case report.

We describe the case of a 76-year-old man presenting with a gas-filled intradural cyst that increased in size over a 10-month period and caused acute bilateral foot drop. The gas-filled intradural cyst was resected from the adherent cauda equina, and histopathological examination identified cystic tissue with degenerated fibrocartilage. Leg pain disappeared immediately following surgery, and the bilateral foot drop resolved within 8 months.
