Background: Sexual dysfunction in males is characterized by the inability to achieve or maintain an erection sufficient for a satisfactory sexual activity. Erectile dysfunction is a common disorder in males and intracavernosal injection of papaverine followed by color Doppler ultrasonography of the penis is used to diagnose and treat vascular impotence. In this study, we examined the relationsh...
Background: Placenta accreta is one of the known causes of maternal mortality and morbidity. If diagnosed before delivery, appropriate actions can be taken. The aim of this study was to investigate the role of scaling combination of risk factors in predicting placenta accreta spectrum (PAS). Methods: In this cross-sectional study, 120 pregnant women with two criteria and more of placenta previ...

Background and Objective: Neonatal sepsis is associated with high mortality and has a favourable outcome when recognized and treated in a timely manner. In resource-limited settings, there is a need for an affordable test with a short turnaround time for timely diagnosis of sepsis. The aim of this study was to find out the role of eosinopenia and neutrophil-to-lymphocyte ratio (NLR) in screenin...

The hypotenuse function, z = √ x2 + y2, is sometimes included in math library packages. Assuming that it is being computed by a straightforward algorithm, in a binary floating point environment, with round to nearest rounding mode, a sharp roundoff error bound is derived, for arbitrary precision. For IEEE single precision, or higher, the bound implies that |z − z| < 1.222 ulp(z) and |z − z| < 1...
