Researchers are developing a new formula for estimating gestational age from ultrasound fetal biometrics. In a study presented on Feb. 6 at the Society for Maternal-Fetal Medicine's annual meeting, ...

Parameter estimation in differential equation models is a critical endeavour in the mathematical modelling of dynamic systems. Such models, represented by ordinary differential equations (ODEs), ...

Introduction: The glomerular filtration rate (GFR) is an important indicator of renal function, and its precise measurement is essential for guiding clinical management. However, studies evaluating ...

Differential equations are commonly used to model dynamical deterministic systems in applications. When statistical parameter estimation is required to calibrate theoretical models to data, classical ...

This paper considers the estimation of the parameters of general systems of stochastic differential-difference equations in which the lag parameters themselves are treated as unknown and are not ...

Determining GFR by inulin clearance is not always practical; practitioners often rely on equation-estimated GFRs. A recent single-center, cross-sectional study evaluated the performance of 4 GFR ...

Many organizations recommend the use of equations that estimate the glomerular filtration rate (GFR) to facilitate the detection, evaluation, and management of chronic kidney disease. 1–11 Indeed, ...

New equations for estimating the relative permeability curves for both water-oil and gas-oil systems have been developed for shaly sands in mixed wettability formations of the Western Desert in Egypt.

The Milky Way Galaxy as seen from the International Space Station Last spring scientists discovered three new Earth-sized planets outside of our solar system, raising the question: could intelligent ...
