A thermodynamic definition of protein folds
Modern techniques in structural biology, like homology modeling, protein threading, protein fold classification, and homology detection have proven extremely useful. For example, they have provided us with evolutionary information about protein homology which has in some many cases lead directly to …

Beyond the Folds: Emergent Properties in Paper
In this body of work I explore the relationship between visual art, information science, and the geometry of paper in an attempt to create a unique visual language with which I make records; not unlike writing in a journal. Using cyanotype, origami, drawing, and digital techniques I co-opt the …

Relations and Folds in Leibniz: Monadological Intimacy
<p>My goal is to provide a clear explanation of Leibniz’s notoriously difficult system of relations. Relations among ‘windowless’ substances that exert no causal power over one another seems like a pipe dream that should be abandoned. However, I demonstrate that each substance expresses its …

The topology of terminal quartic 3-folds
… of non Q-factorial terminal Gorenstein Fano 3-folds. Q-factoriality is a subtle topological property: it depends both on the analytic type and on the position of the singularities of Y . In this thesis, I endeavour to answer some basic questions related to this global topolgical property. …

Three-dimensional kinematics and geometries of thrust-related folds
… with the development of thrust-related folds. First, the complex relationship between fold geometry and along-strike changes in fault displacement and fault shape was considered by extending equations describing conventional two-dimensional folding models into the third dimension. Graphs …

The quantum Johnson homomorphism and symplectomorphism of 3-folds
… between such Fano varieties and cubic 3-folds allows us to factor ... as a product of six-dimensional generalized Dehn twists.

Mesoscopic analysis of folds in the Briggs Formation, Malone Mountains, Texas
… contains highly distorted strata that include folds of different style and orientation as well as boudinage structures. The folds are of three scales. The largest scale occurs in competent carbonate members of the formation and in the overlying Malone and Torcer Formations. These folds trend to …

Creases and folds : applying geometry to a pop-up fashion pavilion
This thesis explores the architectural opportunities embedded in geometric folding by studying the limitations and possibilities of a variety of patterns. In particular; the thesis focuses on the Yoshimura or diamond folding pattern. By manipulating specific rules guiding the diamond fold, the …

Modeling the Mechanical Effects of Liquid Mediated Adhesion Between the Human Vocal Folds
The vocal folds are a complex self-oscillating biological system. In the current research, an equation was developed to model viscous adhesion forces that occur when the collision of the vocal folds results in the formation of a liquid bridge. The adhesion equation was validated using experimental …

An investigation of strain patterns and mesoscopic structures associated with ramp-induced folds
… have potential for use in delineating subsurface folds and their history of development. An investigation of strain and mesoscopic structure was undertaken in the Burkes Garden dome, located in the Narrows thrust sheet in southwest Virginia to delineate the dome's history of formation. The Burkes …

From Protein Folds to Chromatin: Topological Data Analysis and Deep Learning at Multiple Scales
… biological scales—from atomic-level protein folds to the three-dimensional architecture of chromatin—structural organization governs molecular function and regulation. We present two complementary computational frameworks that integrate geometric, topological, and spatial modeling with deep …

Numerical simulation of viscoelastic buckle folds: Implications for stress, fractures, porosity and fluid flow
<p>"Over the past several decades, buckle folds have been exclusively studied by numerous methods. However, lots of assumptions and simplifications are made, which may not result in realistic in-situ stress conditions leading to rock failure. This study represents the first numerical simulation of …

Compact G<sub>2</sub>-orbifolds via Twisted Connected Sums and Associative 3-folds
… well-established construction of compact 7-manifolds carrying an In this thesis, we study the possibility of extending the well-established construction of compact $7$-manifolds carrying an irreducible torsion-free $G_2$-structure, known as the \emph{Twisted Connected Sum}, to the setting of …

Problems in hard and soft matter: From brain folds and Levy localization to active elasticity
… to a zoo of morphologies ranging from primary folds to villi and crypts to secondary folds and are brought about by growth, mechanical stresses, or a combination of the two. We propose a novel model for the description of primary folds in the cerebral cortex. Motivated by the spatial structure …

Covalent Modification that Enhances Protein Properties and Functions and Folds Random Coil into Alpha-Helix
<p>Understanding the fundamental science of aggregation and surface adsorption of proteins is critical for developing protein-based drugs, understanding aggregation-induced diseases and for preventing biofouling that impacts a wide range of industries. In spite of the advances in sensitive and …

Rhizomes, Parasites, Folds and Trees: Systems of Thought in Medieval French and Catalan Literary Texts
… parasites and trees; the second with trees and folds; and the third with folds and rhizomes. However, resonances with the other network theories are discussed as they occur, in order to demonstrate the fundamentally interconnected and often interchangeable nature of these systems. Each chapter …

Modeling and Manufacturing of Dynamic Vocal Folds: First Steps Towards an Active Voice-Box Prosthesis
The movement and control of the vocal folds within the laryngeal cavity enables three crucial physiological functions: 1) allowing respiration by opening, 2) aiding in airway protection by closing, and 3) regulating sound production during phonation. Although treatment options have improved, many …

A Fragile Native State Structure: An Aryl Hydrocarbon Receptor Nuclear Translocator (ARNT) Variant Exhibits Slow Interconversion Kinetics Between two Different Folds
The aryl hydrocarbon receptor nuclear translocator (ARNT) is a promiscuous basic helix-loop-helix Period/ARNT/Single-minded (bHLH-PAS) protein that controls various biological pathways by forming heterodimeric transcriptional regulator complexes with several other bHLH-PAS proteins via the …
