    The simplest case is that of a two-dimensional Hilbert space, known as a qubit. An arbitrary mixed state for a qubit can be written as a linear combination of the Pauli matrices , which together with the identity matrix provide a basis for 2 × 2 {\displaystyle 2\times 2} self-adjoint matrices : [ 9 ] : 126

    The resulting equation for the prior is greatly simplified, as shown below. There are several common parametric empirical Bayes models, including the Poisson–gamma model (below), the Beta-binomial model , the Gaussian–Gaussian model , the Dirichlet-multinomial model , as well specific models for Bayesian linear regression (see below) and ...

    Macrophage polarization is a process by which macrophages adopt different functional programs in response to the signals from their microenvironment. This ability is connected to their multiple roles in the organism: they are powerful effector cells of the innate immune system, but also important in removal of cellular debris, embryonic development and tissue repair.
