Web1. In Classical Electrodynamics (CED) the gauge invariance means independence of the electric and magnetic fields from a particular "choice" of the potentials φ and A. The equation for potentials depend, of course, on the particular choice of the "gauge", and they give different solutions for different gauges. WebDuring synthesis of class II MHC in the endoplasmic reticulum, the α and β chains are produced and complexed with a special polypeptide known as the invariant chain. The nascent MHC class II protein in the rough ER has its peptide-binding cleft blocked by the invariant chain (Ii; a trimer) to prevent it from binding cellular peptides or peptides from …

WebAlgebraic geometry, which is the geometric study of solutions of polynomial equations, has seen in the last few years major developments. Of these, one of the most striking is the invention of modern curve-counting invariants and the understanding that their computation can be understood in terms of solutions of certain differential equations ... WebFeb 6, 2024 · Note that for a category with invariable sites, the rate is zero, hence only sites that are invariant (allowing for missing data) contribute to the tree likelihood. The contribution is 1 for those sites for any tree and for any parameter setting, so by counting the number of invariant sites, the tree likelihood can be calculated in constant time.
