We define the incomplete gamma function ratio for positive N by \begin{align*}\tag{1}P(N, b, X) &= \int^X_0 t^{N-1}e^{-bt} dt/ \int^\infty_0 t^{N-1}e^{-bt} dt \\ &\equiv \int^X_0 D(N, b, t) dt, ...

Rapid, combined and personalized non-invasive stimulation of the precuneus improves associative memory, enhances local gamma expression, and strengthens precuneus–hippocampal connectivity.

I'm afraid my math in this area is a bit deficient, but what I am trying to do is see if there's a way to simplify the function: but I never really learned how to manipulate factorials algebraically, ...

A new study in mice and rats found that restoring certain signals in a brain region that processes smells countered depression. Led by researchers from NYU Grossman School of Medicine and University ...
