Identifying Non-Classical Active Sites As A Tool For Enzyme Inhibition, Marisol Serrano

Open Access Theses & Dissertations

Chagas disease, caused by the parasite Trypanosoma cruzi, is an endemic life-threatening disease that affects mainly the heart. It remains the leading cause of heart failure in Latin American countries. Since current treatments against this parasite are highly toxic and somewhat ineffective, novel and more efficacious types of interventions are desired. Cruzain, identified as the major cathepsin for T. cruzi, plays a major role in the parasite's life cycle; making this enzyme very attractive for potential trypanocidal drugs discovery. The recombinant cruzain is synthesized as a zymogenic pro-protein (PCZN) which possesses a pro domain and a catalytic domain. In this …

Music And What It Is Like: What A Phenomenology Of Perception Tells Us About The Experience Of Music, Chavah Schwartz

Open Access Theses & Dissertations

Ludwig van Beethoven's Symphony No. 9 in D minor, Op.125 is one of his most brilliant and influential musical compositions. However, at the time that he writes his Ninth Symphony, Beethoven is completely deaf. Beethoven exhibits a unique situation where his mind is unaffected in its ability to continue creating new music even though his body is effected in its ability to experience music. Theories of mind, like reductive physicalism and non-reductive dualism, offer a way of understanding Beethoven's conscious experiences of music in relation to physical or non-physical information about mental phenomena associated with conscious experience. Yet, these theories …

Using Word Embeddings For Text Classification In Positive And Unlabeled Learning, Emmanuel Carlo Tafoya

Open Access Theses & Dissertations

Machine Learning is a sub-field of Artificial intelligence that aims to automatically improve algorithms by experience. It has been used successfully to solve various problems, such as playing checkers, or even as simple as word prediction when typing a sentence. These algorithms perform best with large amounts of training data. The more labeled data, the better a machine learning algorithm will be able to recognize patterns. However, the ideal scenario, where there is a large amount of labeled data available to train the algorithm, does not occur all the time. There are cases where labeling data is both time-consuming and …

A New Test For The Mean Vector In High Dimensional Setting, Behzad Aalipur Hafshejani

Open Access Theses & Dissertations

Traditional statistical data analysis mostly includes methods and techniques to deal with problems in which there are many observations but a few variables. Nonetheless, the current inclination is toward more observations but also, toward more variables. Today's observations gathered on individuals are images, curves, or even movies. Unfortunately many traditional methods do not work well in high dimensional settings. As an example Hotelling's test which is well known and widely used in the literature does not work when it comes to high dimensional problems. Consequently statisticians are making an effort to find remedies or new approaches to multivariate mean testing. …

The Impact Of Bicultural Identity On Perceptions Of Self-Efficacy, Miriam J. Alvarez

Open Access Theses & Dissertations

The primary aim of the proposed research was to investigate the role cultural identity plays in regards to academic perceptions, goals, and motivation amongst bicultural college students. Previous research suggests that biculturals experience shifts in mental frames as they navigate differences in cultural settings. Central to this research is the idea that people who have access to multiple cultural meaning systems switch between culturally appropriate behaviors depending on the context. We hypothesize that biculturals' responses to cultural cues involve more than automatic cognitive processes. Cultural frameworks may depend on their motives to embrace or reject particular cultural identities and multiple …

Blind Image Deconvolution Based On Sparsity: Theoretical Justification And Improvement Of State-Of-The-Art Techniques, Fernando Cervantes

Open Access Theses & Dissertations

Observed signals and images are distorted by noise and blurring. In precise terms, blurring is a convolution of the original image with some blurring function. From this viewpoint, to reconstruct the original image, we need to reverse the effects of this convolution, i.e., to ``deconvolve'' the image. Many efficient methods for image deconvolution are known. However, most of these methods assume that we know the blurring function -- or at least that we have some partial information about the blurring function. In some practical situations, however, we do not have this information. In such situations, we need to perform, blind …
