Nonlinear signaling on biological networks: the role of stochasticity and spectral clustering
Gonzalo Hernandez-Hernandez, Jesse Myers, Enric Alvarez-Lacalle +1
Signal transduction within biological cells is governed by networks of interacting proteins. Communication between these proteins is mediated by signaling molecules which bind to r…
Macroscopic consequences of calcium signaling in microdomains: A first passage time approach
Robert Rovetti, Kunal K. Das, Alan Garfinkel +1
Calcium (Ca) plays an important role in regulating various cellular processes. In a variety of cell types, Ca signaling occurs within microdomains where channels deliver localized…
Localization of Polymers in Random Media: Analogy with Quantum Particles in Disorder
Yadin Y. Goldschmidt, Yohannes Shiferaw
In this chapter we review the rich behavior of polymer chains embedded in a quenched random environment. We first consider the problem of a Gaussian chain free to move in a random…
Coupled dynamics of voltage and calcium in paced cardiac cells
Yohannes Shiferaw, Daisuke Sato, Alain Karma
We investigate numerically and analytically the coupled dynamics of transmembrane voltage and intracellular calcium cycling in paced cardiac cells using a detailed physiological mo…
Polymers with self-avoiding interaction in random media: a localization-delocalization transition
Yadin Y. Goldschmidt, Yohannes Shiferaw
In this paper we investigate the problem of a long self-avoiding polymer chain immersed in a random medium. We find that in the limit of a very long chain and when the self-avoidin…
Localization of polymers in a finite medium with fixed random obstacles
Yadin Y. Goldschmidt, Yohannes Shiferaw
In this paper we investigate the conformation statistics of a Gaussian chain embedded in a medium of finite size, in the presence of quenched random obstacles. The similarities and…
