Generalized time reversible
WebRecently, the IFEP was generalized in a manner that minimizes sensory uncertainty, which is a long-term surprisal over a temporal horizon of an organism’s changing environmental niche . ... The broken time-reversal symmetry was attributed to the fact that biological systems are open to the environment. To statistically describe the brain ... Generalised time reversible (GTR) is the most general neutral, independent, finite-sites, time-reversible model possible. It was first described in a general form by Simon Tavaré in 1986. The GTR model is often called the general time reversible model in publications; it has also been called the REV model. The … See more In biology, a substitution model, also called models of DNA sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules (e.g., See more Phylogenetic tree topologies are often the parameter of interest; thus, branch lengths and any other parameters describing the substitution … See more The fact that substitution models can be used to analyze any biological alphabet has made it possible to develop models of evolution for phenotypic datasets (e.g., morphological and behavioural traits). Typically, "0" is. used to indicate the absence of a trait … See more Many useful substitution models are time-reversible; in terms of the mathematics, the model does not care which sequence is the ancestor and which is the descendant so long as all other parameters (such as the number of substitutions per … See more Most of the work on substitution models has focused on DNA/RNA and protein sequence evolution. Models of DNA sequence evolution, where the alphabet corresponds to the four nucleotides (A, C, G, and T), are probably the easiest models to understand. DNA … See more Typically, a branch length of a phylogenetic tree is expressed as the expected number of substitutions per site; if the evolutionary model indicates that each site within an ancestral sequence will typically experience x substitutions by the time it evolves to a … See more Stationary, neutral, independent, finite sites models (assuming a constant rate of evolution) have two parameters, π, an equilibrium vector of base (or character) frequencies and a … See more

This means that reversible gates (and circuits, i.e. compositions of multiple gates) have the same number of inputs as outputs. An inverter (NOT) gate is logically reversible because it can be undone.
