Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. [1] [2] CSIs, brought about by rare genetic changes, provide useful phylogenetic markers that are generally of defined size and they are flanked on both sides by conserved regions to ensure their reliability.
A conserved quantity is a property or value that remains constant over time in a system even when changes occur in the system. In mathematics , a conserved quantity of a dynamical system is formally defined as a function of the dependent variables , the value of which remains constant along each trajectory of the system.
In physics a conserved current is a current, , that satisfies the continuity equation =.The continuity equation represents a conservation law, hence the name. Indeed, integrating the continuity equation over a volume , large enough to have no net currents through its surface, leads to the conservation law =, where = is the conserved quantity.
Georges Seurat, Study for "A Sunday Afternoon on La Grande Jatte", 1884, oil on canvas, 70.5 x 104.1 cm, Metropolitan Museum of Art, New York Georges Seurat painted A Sunday Afternoon between May 1884 and March 1885, and from October 1885 to May 1886, focusing meticulously on the landscape of the park [2] and concentrating on issues of colour, light, and form.
In physics, particularly in quantum field theory, configurations of a physical system that satisfy classical equations of motion are called on the mass shell (on shell); while those that do not are called off the mass shell (off shell).

Designed for everyday walks, jogs and light workouts, the Tree Dasher 2 is the brand's reimagining of an everyday active shoe — one with more responsive foam, extra grip, and an improved fit to ...
In a similar manner, Noether's theorem associates conserved momenta with space-translations, when the symmetry group of the translations is finite-dimensional. Because General Relativity is a diffeomorphism invariant theory, it has an infinite continuous group of symmetries rather than a finite-parameter group of symmetries, and hence has the ...
