IN an exploration of the left atrium via an atrial septal defect during a recent cardiac catheterization in this laboratory, the catheter tip entered the left atrial appendage. An exaggerated "a" wave observed in the pressure contour from the left atrial appendage was striking and exceeded in amplitude the "a" wave from the left atrium proper. Following a similar observation shortly thereafter ...

In this paper, I argue that the positional restrictions of contour tones do not result from their bimoraicity requirement for licensing. The arguments come from the licensing advantage of syllables in positions that are not moraically privileged, the extra levels of markedness distinction in contour tones that go beyond the maximum mora count allowed in the theory, the differences among contour...

UNLABELLED After maxillectomy, prosthetic restoration of the resulting defect is an essential step because it signals the beginning of patient's rehabilitation. An obturator used to restore the defect should be comfortable, restore adequate speech, deglutition, and mastication, and is acceptable cosmetically, Success will depend on the size and location of the defect and the quantity and integr...

This paper carried out a classification study on the quality of different types apples. In order to achieve high-precision high-quality apples in various dimensions, shorten time, improve efficiency, and make it feasible for practical applications. proposes an automatic recognition model OB-Net (for apple appearance quality) based dual-branch structure. The consists two branches, O branch B bra...

Abstract The article uses images from Unmanned Aerial Vehicles (UAVs) for rail diagnostics. main advantage of such a solution compared to traditional surveys performed with measuring vehicles is the elimination decreased train traffic. authors, in study, limited themselves diagnosis hazardous split defects rails. An algorithm has been proposed detect them an efficiency rate about 81% not less t...

Background: With advances in medical imaging systems, digital dermoscopy has become one of the major imaging modalities in the analysis of skin lesions. Thus, automated segmentation or border detection has a great impact on the subsequent steps of skin cancer computer-aided diagnosis using demoscopy images. Since dermoscopy images suffer from artifacts such as shading and hair, there is a need ...

The concept of two different types of extrasystoles, parasystolic and coupled, depends upon two distinguishing characteristics of these beats. The characteristics of the parasystolic extrasystoles are the invariability of the ectopic cycle together with their independence from the basic rhythm. Coupled extrasystoles demonstrate a dependence upon the basic rhythm although they may express some d...

OBJECTIVE To describe a new surgical technique to treat pectus excavatum utilizing low hardness solid silicone block that can be carved during the intraoperative period promoting a better aesthetic result. METHODS Between May 1994 and February 2013, 34 male patients presenting pectus excavatum were submitted to surgical repair with the use of low hardness solid silicone block, 10 to 30 Shore ...

Defects on the craniofacial complex may result in aesthetic defects, functional damage, and psychologic consequences. Previously, surgeons showed no interest in reconstructing the operated area, but in the treatment of the problem, leaving bone contour is a secondary issue. Nowadays, area reconstruction with post-reestablishment of contour and local shape has become one of the surgeon's priorit...

congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...
