A Level Biology Revision "Active Transport"
In this video, we explore active transport. First we look at why active transport is used to move chemicals in and out of cells. We then look at how active transport works, in particular the role of ATP in active transport. This video is aimed at the UK A Level Biology specifications. Stu

We define the Kantorovich dual of Kantorovich problem of Optimal Transport and give a (well known) interpretation in terms of "outsourcing" the task of transporting goods.

How do things move across the cell membrane, either in or out? This animation shows two broad categories of how things pass into or out of a cell: passive transport and active transport. Passive transport is automatic; no input of energy is required. For example, diffusion is a passive p

4 differences between trains and trams
Walking down the street, you may encounter railroads on which a familiar vehicle roams the city with its poetic figure. You can also come across railroads on certain stations where the whole crowd is waiting for that one big metal body. Do you think on these railroads the same vehicles com

Matthias Liero: On entropy transport problems and the Hellinger Kantorovich distance
In this talk, we will present a general class of variational problems involving entropy-transport minimization with respect to a couple of given finite measures with possibly unequal total mass. These optimal entropy-transport problems can be regarded as a natural generalization of classic

Shi-Bing Chen (7/28/22): The optimal partial transport problem
Abstract: In the optimal partial transport problem we are asked to find the most economical way to transport a portion of mass of the source domain to the target domain. It was proved by Caffarelli and McCann that there is a $C^{1,\alpha}$ hypersurface, called free boundary, separating the

Heikki Jylhä: L∞ estimates in optimal transport
It is well-known that for finite p the Lp transportation distances Wp metrize the weak convergence of probability measures (up to a convergence of p-th moments). However, the same result does not hold for the L∞ transportation distance W∞. In light of this, we may ask whether convergence i
