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 ...

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.

Earlier equations for kidney function were derived exclusively from White people and did not consider race. The finding of decreased accuracy in Black Americans later prompted researchers to introduce ...

Partial differential equations can describe everything from planetary motion to plate tectonics, but they’re notoriously hard to solve. Unless you’re a physicist or an engineer, there really isn’t ...

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 ...
