algebraically closed field
Contents
Idea
A field $k$ is algebraically closed if every non-constant polynomial (with one variable and coefficients from $k$) has a root in $k$. It follows that every polynomial of degree $n$ can be factored
uniquely (up to permutation of the factors) as
$p = c \prod_{i = 1}^n (\mathrm{... | 4 | [

Lax equation
Lax equation is used in integrable systems; namely some systems are equivalent to the Lax equation.
Lax equation is a linear ordinary differential equation of the form
$\frac{d L}{d t} = [M, L]$

Multiplication and Division
We think of a multiplication statement like 2 × 3 as meaning Add two threes together , or
3 + 3
and 4 × 9 as add 4 nines together , or
9 + 9 + 9 + 9.
In general, a × b means to add b s together such that the number of b s is equal to a:

Calculation of NNTs in RCTs with time-to-event outcomes: A literature review
Abstract
Background
The number needed to treat (NNT) is a well-known effect measure for reporting the results of clinical trials. In the case of time-to-event outcomes, the calculation of NNTs is more difficult than in
the case of binary dat... | 4 | [

A mathematical model of mitochondrial swelling
Abstract
Background
The permeabilization of mitochondrial membranes is a decisive event in apoptosis or necrosis culminating in cell death. One fundamental mechanism by which such permeabilization events occur is the
calcium-induced mitochondrial permeability transition.... | 4 | [
