lipomas of the gasterointestinal tract are relatively uncommon in clinical practice. most cases are asymptomatic with small tumor size and do not need any special treatment but the large ones are known to cause symptoms such as abdominal pain, obstruction, intussusceptions, and bleeding. the majority (90%) of these lesions are submucosal with predominantly right sided with a slight preponderanc...

Background: Sigmoid Volvulus is the most common form of Volvulus of the gastrointestinal tract and in Uganda; this condition is one of the top causes of intestinal obstruction. It is associated with a pre-existing redundant sigmoid colon which has a narrow attachment of the sigmoid mesentery to the posterior abdominal wall. The objectives of this study was to establish the demographic, dietary ...

Percutaneous endoscopic colostomy (PEC) was first described in 1986, by Jeffrey Ponski [1], who had invented percutaneous endoscopic gastrostomy a few years before that [2]. Performed by 2 operators, PEC consists of placing a tube in the colon during colonoscopy in order to provide antegrade colonic enemas (ACE) in severe constipation or fecal incontinence [3,4]. The PEC tube can also be used a...

Acute sigmoid volvulus is typically caused by an excessively mobile and redundant segment of colon with a stretched mesenteric pedicle. When this segment twists on its pedicle, the result can be obstruction, ischemia and perforation. A healthy, 18-year-old Caucasian woman presented to the emergency department complaining of cramping abdominal pain, distention, constipation and obstipation for t...

We examine the power of constant depth circuits with sigmoid (i.e. smooth) threshold gates for computing boolean functions. It is shown that, for depth 2, constant size circuits of this type are strictly more powerful than constant size boolean threshold circuits (i.e. circuits with boolean threshold gates). On the other hand it turns out that, for any constant depth d , polynomial size sigmoid...

This paper studies an interesting problem: is it possible to predict the crowd opinion about a movie before the movie is actually released? The crowd opinion is here expressed by the distribution of ratings given by a sufficient amount of people. Consequently, the pre-release crowd opinion prediction can be regarded as a Label Distribution Learning (LDL) problem. In order to solve this problem,...

In numerous geometric and physical applications of complex analysis, estimating the sharp bounds coefficient-related problems univalent functions is very important due to fact that these coefficients describe core inherent properties conformal maps. The primary goal this paper was calculate estimates initial some their combinations (the Hankel determinants, Zalcman’s functional, etc.) for class...

Here we research the univariate quantitative approximation, ordinary and fractional, of Banach space valued continuous functions on a compact interval or all real line by quasi-interpolation neural network operators. These approximations are derived establishing Jackson type inequalities involving modulus continuity engaged function its high order derivative fractional derivatives. Our operator...

Deep neural networks have recently achieved state-of-the-art results in many machine learning problems, e.g., speech recognition or object recognition. Hitherto, work on rectified linear units (ReLU) provides empirical and theoretical evidence on performance increase of neural networks comparing to typically used sigmoid activation function. In this paper, we investigate a new manner of improvi...
