Stochastic Approximation Algorithms With Applications To Particle Swarm Optimization, Adaptive Optimization, And Consensus
… of the estimation errors is shown to have a diffusion</p> <p>limit. In Chapter 3, we study a class of stochastic approximation algorithms with regime switching that is modulated by a discrete Markov chain having countable state spaces and two-time-scale structures. In the algorithm, the …

Modelling Nuclear Body Dynamics in Living Cells by 4-D Microscopy, Image Analysis and Simulation
… validates models for nuclear body (NB) dynamics. Simulation tools developed in the course of this work can be used in future work to generate hypotheses about related aspects of nuclear architecture. Initially I examined the mobility of vimentin nuclear bodies bodies (VNB) in interphase by single …

Al-Ga Sacrificial Anodes: Understanding Performance via Simulation and Modification of Alloy Segregation
… and potentially correct this reliability issue. Simulations showed that gallium segregates to the grain boundaries during solidification and then diffuses back into the grains during cooling to room temperature. Simulations also suggest that faster cooling rates and larger grains cause the …

GPCR to Channel Communication in a Membrane Signaling Pathway
… HL-1 cell membrane are replicated in a reaction-diffusion simulation. Based on the simulation, I propose that both protein clustering and the positive bias are crucial to the M2R-GIRK channel signaling pathway.</p>

Electrical and thermal transport in 2D materials: role of environment and imperfections
… 2D material to device analysis, we present a simulation framework for graphene transistors, which includes quantum capacitance, generalized diffusion, carrier density dependent saturation velocity, and device electrostatics. We investigate how these graphene-specific effects change the results …

Materials science and design for germanium monolithic light source on silicon
… absorption in n-Ge. We modified the optical gain simulation based on the above two observations in Ge. We found a broad gain bandwidth of ~ 200 nm from 1550 nm to 1750 nm and a higher net materials gain. We predicted a theoretical lasing threshold current density of 5~10 kA/cm² in the bulk Ge …

On Efficient Algorithms for Stochastic Simulation of Biochemical Reaction Systems
… is formalized in a precise form by a model. A simulation algorithm will realize the dynamic interactions encoded in the model. The simulation can uncover biological implications and derive further predictive experiments. Several successful approaches with different levels of detail have been …

Ab initio modeling of hydrogen pipe diffusion in palladium
… the first time, directly measured hydrogen pipe diffusion. The diffusivities and energy barriers from ab initio simulations support these findings, but open questions remain, the most concerning of which pertains to the unusual jump distances reported from fitting the experimental data. Instead …
