WebAug 5, 2014 · Overview. Since the creation of Ricci flow by Hamilton in 1982, a rich theory has been developed in order to understand the behaviour of the flow, and to analyse the singularities that may occur, and these developments have had profound applications, most famously to the Poincaré conjecture.
WebSep 24, 2024 · The OTDD relies on optimal transport (OT), a flexible geometric method for comparing probability distributions, and can be used to compare any two datasets, regardless of whether their label sets are directly comparable. As a bonus, the OTDD returns a coupling of the two datasets being compared, which can be understood as a set of soft ... camping equipment buckinghamshireWebSome molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core.
