Background: Intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. The aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation. Methods: One hundred and two adult patients underwent contrast e...

In this paper, we use the left(right) stabilizers of a BCKalgebra (X, &lowast, 0) and produce two basis for two different topologies. Then we show that the generated topological spaces by these basis are Bair, connected, locally connected and separable. Also we study the other properties of these topological spaces.

Let \(N=pq\) be an RSA modulus with balanced prime factors. In 2018, Murru and Saettone presented a variant of the cryptosystem based on cubic Pell equation in which public key (N, e) private d) satisfy \(ed\equiv 1\pmod {\left( p^2+p+1\right) \left( q^2+q+1\right) }\). They claimed that classical small attacks such as Wiener’s continued fraction attack do not apply to their scheme. this paper,...

to tumor R2* change. A significant positive correlation observed for tumor microvessel density (r = 0.902, p = 0.003) and inverse correlation observed for tumor size (r = -0.802, p = 0.017). Fig. 2 CD34 staining showing diffuse positive CD34 expression (stained brown, left) and color differentiation of CD34 (black, right) for quantification of tumor microvessel density.

We continue the study of matrices over a supertropical algebra, proving the existence of a tangible adjoint of A, which provides the unique right (resp. left) quasi-inverse maximal with respect to the right (resp. left) quasi-identity matrix corresponding to A; this provides a unique maximal (tangible) solution to supertropical vector equations, via a version of Cramer’s rule. We also describe ...
