Random-walk models are frequently used to model distinct natural phenomena such as diffusion processes, stock-market fluctuations, and biological systems. Here, we present a random-walk model to describe the dynamics of glucose uptake by the sodium-g

We present a statistical mechanical model to describe the dynamics of an arbitrary cotransport system. Our starting point was the alternating access mechanism, which suggests the existence of six states for the cotransport cycle. Then we determined t

No presente trabalho, nós desenvolvemos um modelo de mecânica estatística para a dinâmica do cotransporte. Em particular, foram analisados o simporte de lactose e H+ catalisado pela LacY, e o antiporte de triose-P e Pi catalisado pelo TPT. Em amb

We present Monte Carlo simulations for the transport cycle of Escherichia coli lactose permease (LacY), using as a starting point the model proposed by Kaback et al. [Nat. Rev. Mol. Cell Biol. 2, 610 (2001)NRMCBP1471-007210.1038/35085077], which is b

Influence of gas–surface interaction on gaseous transmission probability through conical and spherical ducts

Autor: Felix Sharipov, Yan B. Barreto

Publikováno v: Vacuum. 121:22-25

Gas flows through ducts are used in the metrology of vacuum in order to develop a continuous flow standard. Usually, the diffuse scattering is assumed for those particles which undergo collisions with the duct surface. However, many experiments point
