1. Four-Body Treatment of the Hydrogen-Antihydrogen System
Abstract : This thesis presents a nonadiabatic (4-body) description of the hydrogen-antihydrogen system at a nonrelativistic level. The properties of the system, the rearrangement processes and the possible existence of resonance states are investigated by using a variational method for coupled arrangement channels, the Gaussian Expansion Method, and the stabilization method.

2. Giant Dipole Resonances as Probes of Local Environment in Molecules, Clusters and Solidsl
Abstract : In this thesis, I study effects of the local environment on the giant dipole resonances (GDR) in lanthanides and actinides. The effects of embedding in jellium, bonding in small molecules and incorporation into different fullerene systems are studied. READ MORE

3. Simulating Functional Cycles and Drug Modulation in Ligand-gated Ion Channels
Abstract : Understanding the intricate motions and conformational changes that govern biological processes remains a fascinating and challenging endeavor. The research presented in this thesis aims to elucidate the dynamic processes underlying biological functions, specifically focusing on the dynamics of pentameric ligand-gated ion channels (pLGICs), which play a crucial role in signal transduction within the brain.

4. Development and Applications of a General Coupled Thermal-hydraulic/Neutronic Model for the
Abstract : Coupled calculations are important for the simulation of nuclear power plants when there is a strongfeedback between the neutron kineticsand the thermal-hydraulics. A general coupled model of the Ringhals-3 Pressurized Water Reactor has beendeveloped for this purpose. READ MORE

5. Voltage-Sensor Domains of Ion Channels : Physiology, Regulation, and Role in Disease
Abstract : Brain function depends on the ability of neurons to sense and respond to electricity, which is mediated by small modules in the neuronal membrane called voltage-sensor domains (VSDs). Disruption of VSD function can cause neurological disease such as epilepsy. READ MORE
