This meta analysis was focused on the comparison using percutaneous nephroscope set and retrograde intra renal surgery to treat renal calculus. The data were obtained from PubMed and Web of Science databases. The published time of literature were from March, 2014, the language included Chinese and English. The literature selection strategies were based on the evaluation and meta analysis on the...

The Calculus of Wrapped Compartments (CWC) is a variant of the Calculus of Looping Sequences (CLS). While keeping the same expressiveness, CWC strongly simplifies the development of automatic tools for the analysis of biological systems. The main simplification consists in the removal of the sequencing operator, thus lightening the formal treatment of the patterns to be matched in a term (whose...

The possibility of partial failure occuring at any stage of computation complicates rigorous formal treatment of distributed algorithms. We propose a methodology for formalising and proving the correctness of distributed algorithms which alleviates this complexity. The methodology uses fault-tolerance bisimulation proof techniques to split the analysis into two phases, that is a failurefree pha...

we propose a method for medical image denoising using calculus of variations and local variance estimation by shaped windows. this method reduces any additive noise and preserves small patterns and edges of images. a pyramid structure-texture decomposition of images is used to separate noise and texture components based on local variance measures. the experimental results show that the proposed...

We develop a stochastic calculus that makes it easy to capture variety of predictable transformations semimartingales such as changes variables, integrals, and their compositions. The framework offers unified treatment real-valued complex-valued semimartingales. proposed is blueprint for the derivation new relationships among processes with specific examples provided below.

We present a call-by-value module calculus that serves as a framework for formal reasoning about simple module transformations. The calculus is stratified into three levels: a term calculus, a core module calculus, and a linking calculus. At each level, we define both a calculus reduction relation and a small-step operational semantics and relate them by a computational soundness property: if t...

Introduction: Healthcare is facing one of the biggest challenges in form Coronavirus-19 pandemic. Various measures are taken by government to curb its spread lockdowns, travel bans, and restrictions upon non-covid admission assimilate resources tackle pandemic has affected patients delayed treatment. Ureteric calculus can present acutely sub-acute forms but without proper treatment due time may...

the current study presents a new analytical method for buckling analysis of rectangular and annular beams made up of functionally graded materials with constant thickness and poisson’s ratio. the boundary conditions of the beam are assumed to be simply supported and clamped. the stability equations were obtained by using conservation of energy. the critical buckling load and first mode shape we...

the current study presents a new analytical method for buckling analysis of circular plates with constant thickness and poisson’s ratio, made of functionally graded material subjected to radial load. governing equations are based on energy method for thin plates. the boundary conditions of the plate are assumed to be simply supported and clamped. the stability equations were obtained by using c...
