A Minimal Model for the Hydrophobic and Hydrogen Bonding Effects on Secondary and Tertiary Structure Formation in Proteins
(University of Waterloo, 2009-04-30)A refinement of a minimal model for protein folding originally proposed by Imamura is presented. The representation of the alpha-helix has been improved by adding in explicit modelling of the entire peptide unit. A four-helix ... -
Minimal model for the secondary structures and conformational conversions in proteins
(University of Waterloo, 2005)Better understanding of protein folding process can provide physical insights on the function of proteins and makes it possible to benefit from genetic information accumulated so far. Protein folding process normally ... -
Mitigating Fiber Nonlinearity with Machine Learning
(University of Waterloo, 2021-12-20)Nowadays, optical communication transmission is based mainly on optical fiber networks. Increasing demands for higher-capacity systems are hampered by signal distortions due to nonlinear effects of the commercial optic ... -
Mode Invisibility Technique - A Quantum Non-Demolition Measurement for Light
(University of Waterloo, 2014-07-14)The act of measuring an observable of a quantum system introduces backaction noise to the measured system. In the most extreme case, the system gets destroyed with its state left unavailable for future measurement. An ... -
Modeling and managing noise in quantum error correction
(University of Waterloo, 2023-10-19)Simulating a quantum system to full accuracy is very costly and often impossible as we do not know the exact dynamics of a given system. In particular, the dynamics of measurement noise are not well understood. For this ... -
Modeling and Simulation of Polarization Mode Dispersion and Polarization Dependent Loss
(University of Waterloo, 2007-01-23)Novel theoretical formulations and efficient simulation methods for polarization-mode dispersion (PMD) and polarization-dependent loss (PDL) that are directly applicable to optical network design are developed. In particular, ... -
Modeling Classical Dynamics and Quantum Effects in Superconducting Circuit Systems

Modeling the Interactions of Antimicrobial Peptides with Cell Membranes
(University of Waterloo, 2022-09-09)Antimicrobial peptides (AMPs) are key molecules of the innate immune system, found among a wide variety of living organisms, including animals, plants, and humans. It is typically composed of cationic and has a unique ... -
Modeling the X-ray absorption of Neodymium ions in cuprate superconductors
(University of Waterloo, 2022-07-18)Electronic nematicity, a breaking of the rotational symmetry of the electronic structure beyond what is expected from the ionic displacements of atoms, has been identified in the (La, M)₂CuO₄ family of the cuprate ... -
Modeling Water Emission from Intermediate Mass Star Formation Regions
(University of Waterloo, 2008-09-22)In this research water emission is modeled from intermediate mass star formations regions placed at 1 kpc. Nine models are created to describe these regions of varying source luminosity ($L=100,500,$ and $1000L_{\odot}$) ... -
Modelling Quantum Well Lasers
(University of Waterloo, 2002)In this thesis, two methods to model quantum well lasers will be examined. The first model is based on well-known techniques to determine some of the spectral and dynamical properties of the laser. For the spectral ... -
Modification of a Dilution Refrigerator for In-Field SQUID Magnetometry of Dy2Ti2O7
(University of Waterloo, 2015-10-01)The pyrochlore oxide family is a well known class of geometrically frustrated magnets with novel properties such as residual entropy at low temperatures and monopole-like quasiparticle excitations. One member of this ... -
Modified Gravity and the Phantom of Dark Matter
(University of Waterloo, 2009-08-13)Astrophysical data analysis of the weak-field predictions support the claim that modified gravity (MOG) theories provide a self-consistent, scale-invariant, universal description of galaxy rotation curves, without the need ... -
