background vascular ring is less than 1% of congenital heart disease. double aortic arch (daa) is the most common form of it.  its detecting is important because of the effects of pressure on the esophagus and trachea. case report in this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, wer...

background: endosonography is a distinct method in evaluating gastrointestinal (gi) structural lesions, particularly in the pancreatobiliary system. this procedure has made a fundamental change in the diagnosis of pancreatic mass lesions through fine needle aspiration (fna). this study aims to evaluate the results and efficacy of endosonographic fine needle aspiration (eus-fna) in patients pres...

We examined three intervention methods for their efficacy in preventing aspiration in 25 patients with Parkinson's disease (PD) and 23 patients with degenerative cerebellar ataxia (CA). On videofluoroscopic examination. 13 patients with PD (52%) and 7 patients with CA (30.4%) showed aspiration. In all PD patients and 5 patients with CA, no aspiration was observed after changing the food form. W...

BACKGROUND Dysphagia is one of the most dangerous symptoms of acute stroke. Various screening tools have been suggested for the early detection of this condition. In spite of conflicting results, measurement of oxygen saturation (SpO2) during clinical swallowing assessment is still recommended by different national guidelines as a screening tool with a decline in SpO2 ≥2% usually being regarded...

The article presents the results of testing hypothesis about presence destructive tendencies in socio-psychological status mothers families raising children with visual impairments, as well disharmonious nature their psychological culture. Mothers from 48 took part experiment. Negative trends such as: excessive importance mother’s role family circle; estrangement spouse; intimacy child to detri...

In this paper, we present and evaluate an approach to incremental dialogue act (DA) segmentation and classification. Our approach utilizes prosodic, lexico-syntactic and contextual features, and achieves an encouraging level of performance in offline corpus-based evaluation as well as in simulated human-agent dialogues. Our approach uses a pipeline of sequential processing steps, and we investi...

How can the classical psychological laws be explained and unified? It is proposed here that scale-invariance is a unifying principle. Distributions of many environmental magnitudes are observed to be scale invariant; that is, the statistical structure of the world remains the same at different measurement scales [Mandelbrot, B., 1982. The Fractal Geometry of Nature (2nd Edn.). W.H. Freeman, San...

We present a novel synthesis method for procedural generation of complex curves. Our approach takes a simple example input curve specified by a user and automatically generates complex curves that resembles the input. The algorithm preserves many of the input shape features such as tangent directions, curvature and branch nodes. The overall system is simple and can be used to generate different...
