The Modeling and Analysis of the Apoptotic BAD/tBID/BAK Pathway as a Chemical Reaction Network
… error or missing altogether. Chemical reaction network theory, however, provides a theoretical approach to complement the initial numerical analysis without having to specify rate constant values. We extend the global asymptotic stability and robustness results in [92] to include any …

Stochastic Simulation Methods for Biochemical Systems with Multi-state and Multi-scale Features
… Then we propose two new methods that extend the Network-Free Algorithm (NFA) for rule-based models. Numerical results are provided to show the performance improvement by our new methods. In the second part, we investigate two simulation schemes for the multi-scale feature: Haseltine and …

Inferring interactions, expression programs and regulatory networks from high throughput biological data
(cont.) For the networks level I present an algorithm that efficiently combines complementary large-scale expression and protein-DNA binding data to discover co-regulated modules of genes. This algorithm is extended so that it can infer sub-networks for specific systems in the cell. Finally, I …

From network to pathway: integrative network analysis of genomic data
… to combine different types of genomic data for a network or pathway view of biological systems. Motivated by such needs, we make efforts in this dissertation to develop integrative framework for pathway analysis. Specifically, we dissect the molecular pathway into two parts: protein-DNA …

Genome-scale metabolic modelling of Salmonella and Lactobacillus species
… host environment, a method for identication of a sub-network of the model, required for viability on all growth supporting carbon sources was developed. The impact of sequentially removing combinations of reactions in the sub-network from the genome-scale model was evaluated. This analysis …

Inhibition stabilized network model in the primary visual cortex
In this paper, we studied neural networks of both excitatory and inhibitory populations with inhibition stabilized network (ISN) models. In ISN models, the recurrent excitatory connections are so strong that the excitatory sub-network is unstable if the inhibitory firing rate is fixed; however, the …

Measuring Effectiveness in the Domestic Intelligence Community: Taking a Configurational Approach to Explain Organizational Outcomes in the National Network of Fusion Centers
… organizational level outcomes within a whole network--the national network of fusion centers. Fusion centers are state and local organizations that fuse threat-related intelligence and information by working with federal, state, and local law enforcement as well as other security partners in …

Power-optimal MIMO two-way relay networks
In this dissertation, we study MIMO two-way relay networks consisting of singleantenna users which wish to exchange information with the help of multiple multiantenna relays. The problem we aim to solve is to minimize the total transmit power consumed in the entire network while certain …
