Steady-state parameter sensitivity in stochastic modeling via trajectory reweighting
Steady-state parameter sensitivity stochastic modeling trajectory reweighting
2012/2/28
Parameter sensitivity analysis is a powerful tool in the building and analysis of biochemical network models. For stochastic simulations, parameter sensitivity analysis can be computationally expensiv...
Stochastic theory of protein synthesis and polysome: ribosome profile on a single mRNA transcript
ribosome traffic, master equation, extremum current hypothesis, distance-headway,TASEP.
2011/8/29
The process of polymerizing a protein by a ribosome, using a messenger RNA (mRNA) as the corresponding template, is called translation. Ribosome may be regarded as a molecular motor for which the mRNA...
Infinite-Period Phase Transition versus Nucleation in a Stochastic Model of Collective Oscillations
Infinite-Period Phase Transition Collective Oscillations
2011/9/2
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al. [Phys. Rev. Lett. 96, 145701 (2006)] to exhibit a phase transition at a critical value of the coupling...
Exact solution of a stochastic protein dynamics model with delayed degradation
protein dynamics model
2011/9/29
We study a stochastic model of protein dynamics that explicitly includes delay in the degradation.We rigorously derive the master equation for the processes and solve it exactly. We show that the equa...
Stochastic analysis of a miRNA-protein toggle switch
Toggle switch, chemical master equation, stochastic versus deterministic, biochemical reactions
2011/9/5
Within systems biology there is an increasing interest in the stochastic behavior of genetic and biochemical reaction networks. An appropriate stochastic description is provided by the chemical master...
Stochastic quantization of fields inspired by biological evolution
Stochastic quantization biological evolution
2011/1/6
The quasi-species equation describes the evolution of the probability that a random individual in a population carries a given genome. Here we map the quasi-species equation for individuals of a self-...
Stochastic kinetic models: Dynamic independence, modularity and graphs
Stochastic kinetic models Dynamic independence modularity graphs
2010/11/16
The dynamic properties and independence structure of stochastic kinetic models (SKMs) are analyzed. An SKM is a highly multivariate jump process used to model chemical reaction networks, particularly ...
Stochastic emergence of multiple intermediates detected by single-molecule quasi-static mechanical unfolding of protein
single-molecule detection protein folding molecular force microscopy molecular dynamics energy landscape
2010/12/2
Experimental probing of a protein-folding energy landscape can be challenging, and energy landscapes comprising multiple intermediates have not yet been defined. Here, we quasi-statically unfolded sin...
Mechanism of muscle contraction based on stochastic properties of single actomyosin motors observed in vitro
molecular motor Brownian motion single molecule preferential landing loose coupling
2010/12/2
We have previously measured the process of displacement generation by a single head of muscle myosin (S1) using scanning probe nanometry. Given that the myosin head was rigidly attached to a fairly la...
