Short-distance Transport of Resources02:12

Short-distance Transport of Resources

14.9K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Carrier Transport

1.2K
The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:

Electrical Transport

207
The electrical transport property of a material is defined by its resistance and conductivity. Resistance is the measure of a material's ability to resist the flow of electric current, while conductivity gauges its ability to allow the current to pass through, depending on the geometry of the measurement cell, such as electrode spacing and area. Conductivity is measured in Siemens (S). There are different types of conductance, including specific conductance, equivalent conductance, and molar...

Transport Number01:31

Transport Number

250
The transport number is the fraction of the total current carried by an ion in an electrolyte solution. It is defined as the ratio of the current carried by a specific ion to the total current flowing through the solution. The transport number, t, is central to understanding ionic mobility, which describes how fast an ion moves under the influence of an electric field. This link connects the physical behavior of ions in solution to the chemical processes that occur during electrochemical...

Carrier-Mediated Transport01:06

Carrier-Mediated Transport

1.6K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

Nonlinear Pharmacokinetics: Role of Transporters

399
A drug's nonlinear kinetics can be influenced by a diverse range of transporter proteins that serve as crucial players in drug distribution. These transporters, found within cells, can enhance or reduce local drug concentrations by facilitating the influx or efflux of drugs. For instance, the expression of xenobiotic transporters can be influenced by factors such as age and gender, potentially impacting the linearity of drug response.
Polymorphisms occurring in drug transporters can alter...

Area of Science:

  • Numerical Analysis
  • Differential Geometry
  • Stochastic Processes

Background:

  • The JKO scheme is a time discretization for Wasserstein gradient flows.
  • Wasserstein distance can be computationally intensive on manifolds.
  • Fokker-Planck equations model diffusion processes.

Purpose of the Study:

  • To generalize the JKO scheme using arbitrary transport costs on manifolds.
  • To establish convergence to the Riemannian Fokker-Planck equation.

Main Methods:

  • Modification of the JKO scheme by replacing Wasserstein distance with general transport costs.
  • Analysis of convergence properties under conditions on the cost function's Hessian.
  • Application to Fokker-Planck equations on compact and complete Riemannian manifolds.

Main Results:

  • Convergence of the modified JKO scheme to the Riemannian Fokker-Planck equation when the cost induces a Riemannian metric.
  • Demonstration of applicability on compact submanifolds with Neumann boundary conditions and complete Riemannian manifolds.
  • Successful application to Hessian manifolds using Bregman divergence as a cost.

Conclusions:

  • The generalized JKO scheme provides a flexible framework for discretizing gradient flows on manifolds.
  • This approach offers computational benefits when Riemannian distance is intractable.
  • The method connects optimal transport, geometric analysis, and numerical methods effectively.
