M-theory on G2 Manifolds Moduli to Phenomenology
(2022)
String theories are good candidates for unifying the Standard Model and general relativity. M theory is the non-perturbative limit of all string theories. Moreover, it has been shown that M theory should be compactified ...
Development of Radio Science Techniques and a Planetary Mission Concept
(2023)
Radio Occultation (RO) is a remote sensing observation which takes advantage of radio signals from the communications system of a spacecraft to measure the Doppler shift of the signals as they pass through the atmosphere. ...
Medical Image Analytics (Radiomics) with Machine/Deeping Learning for Outcome Modeling in Radiation Oncology
(2020)
Image-based quantitative analysis (radiomics) has gained great attention recently. Radiomics possesses promising potentials to be applied in the clinical practice of radiotherapy and to provide personalized healthcare for ...
Deterministic-Kinetic Computational Analyses of Expansion Flows and Current-Carrying Plasmas
(2021)
Spacecraft electric propulsion (EP) takes advantage of the ability of electric and magnetic fields to accelerate plasmas to high velocities to generate efficient thrust. The thermionic hollow cathode is a critical component ...
Holography, Supergravity, and the Weak Gravity Conjecture
(2020)
This dissertation represents my work on three different subjects relating to quantum gravity and the AdS/CFT correspondence.
First, we review a holographic computation of the one-loop corrections to the Weyl anomaly on ...
Into the Rainbow: Kinetics of the Bacterial Reaction Center Using Broadband Two-Dimensional Electronic Spectroscopy
(2021)
Photosynthesis is a process by which light is converted to chemical energy, and which is responsible for nearly all life on Earth. A more complete understanding of the mechanisms behind photosynthesis, particularly the ...
The Extraction of dbar/ubar Ratio in Nuclear Media
(2020)
This work examines the momentum distribution of the “sea” quarks within the proton and how these distributions are modified in the nuclear medium. The nucleon sea, which is made of gluons and quark-antiquark pairs, possesses ...
Understanding the Optical and Photophysical Properties of Organic and Hybrid Macromolecules and Polymers for Solar Cell Application
(2021)
Organic solar cell materials represent a better sustainable alternative relative to inorganic materials in terms of lower cost, ease of large-scale processing, better absorptivity, ease of tunability, and unique flexibility ...
Magnetized, Laser-Driven, Plasma Experiments at Astrophysically Relevant Conditions and Proton Imaging of Magnetic Fields
(2020)
This thesis presents analysis relevant to two magnetized, astrophysically relevant experimental campaigns that were performed at the OMEGA laser facility. The magnetic fields of these systems were measured using proton ...
Ultrafast Coherent Imaging Spectroscopy of Van-der-Waals Materials
(2022)
Transition metal dichalcogenides (TMDs) have received considerable attention in the past decade for their optoelectronic applications in photovoltaics, lasers, and quantum information. In the monolayer limit, these materials ...
