The originating pattern of deep inferior epigastric artery: anatomical study and surgical considerations.

Purpose: Studies focusing on the originating patterns of the deep inferior epigastric artery (DIEA) have not been conducted. Here, we analyzed the vascular anatomy of the DIEA with computed tomographic angiography (CTA) to provide assistance during proximal pedicle dissection of a DIEA-based flap.

Methods: We conducted a retrospective study on patients who had undergone breast reconstruction with the transverse rectus abdominis musculocutaneous flap and the deep inferior epigastric perforator flap from March 2006 to October 2016.

Atomic Layer Deposition of Zirconium-Based High-k Metal Gate Oxide: Effect of Si Containing Zr Precursor.

Zirconium based thin film have been deposited by atomic layer deposition (ALD) process using Zr and Si containing Zr precursor with ozone as oxidant. We have pursued a means to control composition by varying Zr and Si containing precursor by cycle frequency. The molar ratio of Si to Zr in the Zr based films was 0.
