In existing imaging algorithms for wide-beam multiple-receiver synthetic aperture sonar (SAS) systems, the double-square-root (DSR) range history of each receiver is generally converted into sum a single-square-root (SSR) and an error term using displaced phase center (DPCA) approximation. Therefore, before imaging, receiver’s needs to be individually compensated in azimuth frequency domain, wh...

Potential scatter of simulation results caused for exampleby buckling, is still a challenging issue for the predictability. Principle component analysis (PCA) is a well-known mathematical method for data analysis. In order to characterize scatter PCA analysis was applied to the simulation results from a number of runs using all node positions at all time steps. For industrials relevant problems...

El desarrollo de hiponatremia figura entre las complicaciones de la diálisis peritoneal1–4 y se ha referido asociada a retención de osmolitos (icodextrina), hiperglucemia, estados catabólicos, pérdida intracelular de potasio o fósforo5 o fallo de ultrafiltración6. Por otro lado, se ha demostrado correlación positiva entre la pérdida de sodio y el volumen de ultrafiltrado, por lo que se recomien...

BACKGROUND In vitro studies of peritoneal dialysis (PD) solutions demonstrated that a biocompatible fluid with neutral-pH and low glucose degradation products (LF) has better biocompatibility than a conventional acidic lactate-buffered fluid (CF). However, few clinical trials have investigated the effects of the biocompatible solution on residual renal function (RRF). We performed a prospective...

The problem of estimating the parameters in a generalized linear model when a covariate is subject to censoring is studied. A newmethod based on an estimating function approach is proposed. The method does not assume a parametric form for the distribution of the response given the regressors and is computationally simple. In the linear regression case, the proposed approach implies the use of m...

As the need to discovers new mineral deposits and occurrences has intensified in recent years, it become increasingly apparent that we map potentials via integrated information on basis of metallogeny. Occurrences mineralization such as tungsten (W), tin (Sn), columbium (Nb), tantalum (Ta), gold (Au), copper (Cu), lead (Pb), zinc (Zn), manganese (Mn) monazite (Mnz) have been discovered Rwanda. ...

Abstract Background and Aims Sacubitril/valsartan, the first approved angiotensin receptor neprilisin inhibitor (ARNi), is current cornerstone in treatment of heart failure with reduced ejection fraction (HFrEF), reducing hospitalizations mortality. However, patients chronic kidney disease stage 5D, who have highest prevalence congestive failure, its use still not approved. The aim this study w...
