Predicting the thioflavin fluorescence of retinal amyloid deposits in association with Alzheimer’s disease and differentiating amyloid protein from alpha-syn
(University of Waterloo, 2020-09-02)Alzheimer’s disease (AD) is a neurodegenerative disease and the most common cause of dementia. According to the World Health Organization (WHO) in 2019, dementia affects around 50 million people worldwide and this number ... -
Prehydrated Electron and Its Role in Ionizing Radiation Induced DNA Damage and Molecular Mechanisms of Action of Halogenated Sensitizers for Radiotherapy of Cancer
(University of Waterloo, 2012-10-05)Despite advances in technology and understanding of biological systems in the past two decades, modern drug discovery is still a lengthy, expensive, difficult and inefficient process with low rate of new therapeutic ... -
Probing Accretion Turbulence in the Galactic Centre with EHT Polarimetry
(University of Waterloo, 2019-01-09)We explore the origin and the influence of the interstellar scattering on the observation of Sgr A*, and the method to mitigate this scattering via Event Horizon Telescope (EHT) polarimetry. Interstellar scattering is due ... -
Probing Dark Matter from the Galaxy to the Cosmic Web
(University of Waterloo, 2020-01-23)Dark matter, although invisible, accounts for the majority of matter of the universe. How this invisible component affects cosmic structure formation is one of the primary lines of inquiry in physical cosmology, and the ... -
Probing High Energy Physics Through Gravitational Waves

Probing the dark universe with gravitational lensing
(University of Waterloo, 2018-09-17)Since its early success as an experimental test of the theory of general relativity in 1919, gravitational lensing has come a long way and is firmly established as an indispensable element for many astrophysical applications. ... -
Probing the Environmental Dependence of Star Formation in Satellite Galaxies using Orbital Kinematics
(University of Waterloo, 2013-09-03)(Abridged) Physical processes regulating star formation in satellite galaxies represent an area of ongoing research, but the projected nature of observed coordinates makes separating different populations of satellites ... -
Probing the large-scale clustering of fast radio bursts with CHIME/FRB
(University of Waterloo, 2021-08-23)Explaining the nature of extragalactic fast radio bursts (FRBs) has puzzled astrophysicists since 2007. In this thesis, we introduce the CHIME/FRB instrument, an FRB search engine that could solve this puzzle through FRB ... -
Probing the Unruh and Hawking effects using Unruh-DeWitt detectors
(University of Waterloo, 2017-10-18)Quantum field theory is so far the best description of the fundamental laws of Nature, yet it does not fully incorporates gravitation. The first attempt toward unifying the quantum field theory and gravity is a semi-classical ... -
Probing universality with entanglement entropy via quantum Monte Carlo
