Stochastic Dynamics on Integrable Lattice Models
… the translation invariant Gibbs measures of the stochastic sixvertex model are stationary measures of the process. Using structure preserving local moves for the dimer model, in Chapter 3 we construct another surface growth model in the AKPZ universality class, which has the dimer model Gibbs …

Stochastic dynamics of adhesion clusters under force
… adhesion molecules is a thermally activated, stochastic process. In this work, a stochastic model for the rupture and rebinding dynamics of clusters of parallel adhesion molecules under force is presented. In particular, the influence of (i) a constant force as it may be assumed for cellular …

Stochastic dynamics in olfactory signal transduction and development
… In the present work, methods from nonlinear dynamics combined with network theory (namely stoichiometric network analysis) are used to identify a specific negative feedback mechanism that accounts for a number of recently measured experimental results, e.g. oscillations in calcium …

Stochastic dynamics of cell adhesion in hydrodynamic flow
In this thesis the interplay between hydrodynamic transport and specific adhesion is theoretically investigated. An important biological motivation for this work is the rolling adhesion of white blood cells experimentally investigated in flow chambers. There, specific adhesion is mediated by weak …

A Topological Study Of Stochastic Dynamics On CW Complexes
<p>In this dissertation, we consider stochastic motion of subcomplexes of a CW complex, and explore the implications on the underlying space. The random process on the complex is motivated from Ito diffusions on smooth manifolds and Langevin processes in physics. We associate a Kolmogorov equation …

Stochastic Dynamics of Cascading Failures in Electric-Cyber Infrastructures
… tractable continuous-time Markov chain model for stochastic dynamics of cascading failures in power grids is constructed while retaining key physical attributes and operating characteristics of the power grid. The key idea of the proposed framework is to simplify the state space of the complex …

Stochastic dynamics in spatially extended physical and biological systems
… thesis, I discuss three different problems of stochastic nature in spatially extended systems: (1) a noise induced mechanism for the emergence of biological homochirality in early life self-replicators, (2) the amplification effect of nonnormality on stochastic Turing patterns in reaction …

Stochastic Dynamics Models of Plant Population and Species Diversity
This study presents sophisticated error analysis of the Shannon index in time and space. Error of current estimate increases proportional to measurement while the total forecasting error increases very fast in time. Spatial variation contributes the most to the total error of the Shannon index. …

The Stochastic Dynamics of Optomechanical Sensors for Atomic Force Microscopy
This work explores the stochastic dynamics and important diagnostics of a mechanical resonator (nanobeam) used in cavity optomechanical sensors for atomic force microscopy. Atomic force microscopy (AFM) is a tool to image surface topology down to the level of individual atoms. Conventional AFM has …

Statistical Modeling, Learning and Computing for Stochastic Dynamics of Complex Systems
<p>With the recent advances in sensor technology, it is much easier to collect and store streams of system operational and environmental (SOE) data. These data can be used as input to model the underlying behavior of complex engineered systems and phenomenons if appropriate algorithms with …

Stochastic dynamics with singular lower order terms in finite and infinite dimensions
In this work, we aim to study several stochastic dynamics with singular coefficients. The results consist of three parts. In the first part, we study a class of second order parabolic equations $$nabla (a(t,x) cdot nabla u(t,x))+b(t,x)cdot nabla u(t,x)+V(t,x) u(t,x)-partial_{t}u(t,x)=0 eqno (1)$$ …

Stochastic dynamics and fluctuation theorems in Brownian, feedback-controlled, and optical cavity systems
This thesis investigates stochastic dynamics in a range of classical systems, with a focus on fluctuation theorems and the physical interpretation of the quantities entering these relations. It begins with an investigation of the added mass effect in harmonically coupled underdamped Brownian …

The Stochastic Dynamics of an Array of Micron Scale Cantilevers in Viscous Fluid
The stochastic dynamics of an array of closely spaced micron scale cantilevers in a viscous fluid is considered. The stochastic cantilever dynamics are due to the constant buffeting of fluid particles by Brownian motion and the dynamics of adjacent cantilevers are correlated due to long range …
