A case with four-channel aortic dissection [PDF]

European Journal of Cardio-Thoracic Surgery, 2005
A 65-year-old male with four-channel aortic dissection successfully underwent replacement of the thoracoabdominal aorta, reconstruction of the celiac, superior mesenteric artery, renal arteries, and 5 pairs of intercostals or lumbar arteries using deep hypothermic technique.

A Single Image Enhancement Technique Using Dark Channel Prior

Applied Sciences, 2021
In this paper, we propose a novel single image enhancement technique for defogging by using dark channel prior. The traditional dark channel prior methods for defogging have problems of high time complexity, edge effect, and failure of dark channel prior.

Four-channeled aortic dissection and rupture [PDF]

European Journal of Cardio-Thoracic Surgery, 1997
A four-channeled aortic dissection is quite rare, which is a highly life-threatening situation predisposing to aortic rupture. We report a successful management of a four-channeled aortic dissection and an aortic rupture in a 59-year-old woman with Marfan's syndrome 11 years after an initial Bentall procedure for DeBakey type I dissection.

An Improved Wave-Variable Based Four-Channel Control Design in Bilateral Teleoperation System for Time-Delay Compensation

IEEE Access, 2018
Good transparency performance (including position tracking and force feedback) is a significant issue for teleoperation control design. The four-channel control approach, which is based on the impedance matching between the master and slave, is an ...

Classification of four-class motor imagery employing single-channel electroencephalography. [PDF]

PLoS ONE, 2014
With advances in brain-computer interface (BCI) research, a portable few- or single-channel BCI system has become necessary. Most recent BCI studies have demonstrated that the common spatial pattern (CSP) algorithm is a powerful tool in extracting ...

RoboPol: a four-channel optical imaging polarimeter [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We present the design and performance of RoboPol, a four-channel optical polarimeter operating at the Skinakas Observatory in Crete, Greece. RoboPol is capable of measuring both relative linear Stokes parameters q and u (and the total intensity I) in one sky exposure.

Quaternionic Lattice Structures for Four-Channel Paraunitary Filter Banks

EURASIP Journal on Advances in Signal Processing, 2007
A novel approach to the design and implementation of four-channel paraunitary filter banks is presented. It utilizes hypercomplex number theory, which has not yet been employed in these areas.
