A PHASE relation familiar to students of applied mathematics exists between a simple harmonic oscillation and its derivative. Similar relations exist between exponential functions and their ...

Estimating the time derivatives of a signal is a common task in science. A well-known example is the growth rate of a population of cells, which is defined as the time derivative of the logarithm ...

Posterior means of positive functions can be expressed as the ratio of integrals which is called fully exponential form. When approximating the posterior means analytically, we usually use Laplace's ...
