Standing-Gradient Osmotic Flow
At the ultrastructural level, epithelia performing solute-linked water transport possess long, narrow channels open at one end and closed at the other, which may constitute the fluid transport route (e.g., lateral intercellular spaces, basal infoldings, intracellular canaliculi, and brush-border microvilli). Active solute transport into such folded structures would establish standing osmotic gr...
متن کاملAn Analogue Program for Standing-Gradient Osmotic Flow
Diamond and Bossert (1) proposed a model of standing-gradient osmotic flow as a mechanism to explain the coupling of water and solute transport in epithelia. In their computations they used a digital program in F O R T R A N on an IBM 7094 to solve for the two dependent variables, C and v, where C was the osmolar concentration at any point, x along the channel and v was the linear velocity at t...

متن کاملDynamics of osmotic fluid flow
The classical thermodynamic treatment of osmotic pressure is quite sufficient to describe equilibrium situations and compute most quantities of interest without reference to any molecular model (see, for example, Finkelstein, 1987). However, one's intuition is always aided by molecular models, and a microscopic picture can be quite useful when thinking about osmotic flow in unfamiliar situation...
متن کاملStein Variational Gradient Descent as Gradient Flow
Stein variational gradient descent (SVGD) is a deterministic sampling algorithm that iteratively transports a set of particles to approximate given distributions, based on a gradient-based update that guarantees to optimally decrease the KL divergence within a function space. This paper develops the first theoretical analysis on SVGD. We establish that the empirical measures of the SVGD samples...
