Heun functions, which generalise the well‐known hypergeometric functions, are solutions to the Heun differential equation – a second‐order linear differential equation with four regular singular ...

Almost periodic functions serve as a powerful conceptual framework in analysing differential equations whose coefficients or forcing terms exhibit recurrent behaviour over time. Rooted in the ...

A new equation for calculating a person's kidney function — their estimated glomerular filtration rate (eGFR) — worked as well with serum cystatin C as it did with serum creatinine as the biomarker.

👉 Learn how to graph piecewise functions. A piecewise function is a function that has more than one sub-function for different sub-intervals (sub-domains) of the function's domain. To graph a ...

Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a ...
