Emergent coherent structures in nonequilibrium field theory.
Coherent states. Quantum field theory. Nonlinear theories.
In this thesis we study the properties of time-dependent, nontopological configurations and their effect on the macroscopic properties of a system described by a nonlinear field theory. These structures seem to be ubiquitous in relativistic field...

Nonequilibrium dynamics of emergent field configurations.
Nonequilibrium thermodynamics -- Mathematical models. Fluctuations (Physics) -- Mathematical models. Phase transformations (Statistical physics) -- Mathematical models. Configurations.
The processes by which nonlinear physical systems approach thermal equilibrium is of great importance in many areas of science. Central to this is the mechanism by which energy is transferred between the many degrees of freedom comprising these...

The cognitive dynamics underlying decision-making : interactions between attention memory and reward in action control / by Kanghoon Jung.
A fundamental question in decision neuroscience is how cognitive processes underlying decision-making give rise to efficient decisions, especially in complex situations with multiple choice options, and each option consisting of multiple attributes...

Assortativity and the robustness of gene regulatory networks / by Dov A. Pechenick.
Robustness to genetic perturbations is a fundamental property of all living things. The genetic code is degenerate, RNA secondary structure is robust to sequence changes, and protein structure is robust to amino acid substitutions. Complex systems...

Mesh-Mon: a monitoring and management system for wireless mesh networks.
Wireless communication systems. Computer networks. Routers (Computer networks).
A mesh network is a network of wireless routers that employ multi-hop routing and can be used to provide network access for mobile clients. Mobile mesh networks can be deployed rapidly to provide an alternate communication infrastructure for...

Nonequilibrium dynamics of phase transitions.
Phase transformations (Statistical physics) -- Mathematical models. ; Differential equations Nonlinear -- Numerical solutions. ; Nonequilibrium thermodynamics -- Mathematical models. ; Mathematical physics.
Phase transitions occur in such diverse and important systems as ferromagnets, liquid crystals and the early Universe. The dynamics of phase transitions such as these have been studied for decades, but the analytical models still need a great deal...

Genetic variants among G-protein coupled receptors and implications for cardiovascular disease.
G proteins -- Receptors. Cardiovascular system -- Diseases -- Genetic aspects. Medical Term Receptors, G-Protein-Coupled -- genetics.
Single-nucleotide polymorphisms (SNPs), particularly non-synonymous variants, provide opportunities for deciphering pathophysiological protein influence. An ideal group for realizing these opportunities is the GPCR-superfamily. Principles from...

Improvements in conservative parallel simulation of large-scale models.
Large scale systems -- Mathematical models. Digital computer simulation. Parallel processing (Electronic computers). Computer algorithms.
Modeling real-world large-scale systems is inherently challenging due to their size and complexity. Detailed simulation of large-scale models requires tremendous amounts of computing power and memory space. Parallel discrete-event simulation...

Dynamical scaling behavior in non-equilibrium quantum phase transitions
Phase transformations (Statistical physics);""Scaling laws (Nuclear physics)"";""Critical phenomena (Physics)"";""Nuclear spin.""
This thesis focuses on the emergence of universal dynamical scaling in quantum critical spin systems driven out of equilibrium, with emphasis on quench dynamics which involves isolated standard critical points, multi-critical points, and...
