Investigating Latent State and Uncertainty Representations in Reinforcement Learning

Creator:: Koul, Anurag
Abstract:: Learning latent space representations of high-dimensional world states has been at the core of recent rapid growth in reinforcement learning(RL). At the same time, RL algo- rithms have suffered from ignored uncertainties in the predicted estimates of model-free or model-based methods. In our work, we investigate both of these aspects...

Engineering an Ex-Vivo System to Study Transport Phenomena in the Human Intervertebral Disc

Creator:: Shalash, Ward
Abstract:: Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...

Investigating Multimodal Therapies with Nanotechnology to Engineer Advanced Chemoradiation Platforms

Creator:: DuRoss, Allison N.
Abstract:: The potential for nanomedicine to reduce toxicity and improve therapeutic response to radiation is vast. Clinically, this potential has thus far only begun to be realized with the recent success of the radioenhancing nanoparticle, NBTXR3 by Nanobiotix. Radioenhancing nanoparticles, however, represent only a small class of nanomaterials that may be...

The Science of Becoming Noble: Rationalizing Aristocracy through Diagrammatic Notations for Dance and Drill in the Age of Enlightenment

Creator:: Caulkins, Tamara L.
Abstract:: During the eighteenth century, diagrams increasingly became an important aspect of scientific inquiry. Diagrams employed simplification as a strategy for representing complex information, played a role in standardizing scientific language, and served as instruments of reason to think through and communicate problems and findings in mathematics, physics, chemistry, astronomy, natural...

Developing a 2D Cross-section Training Strategy for 3D Volume Segmentation by Analyzing Human Perception and Cognitive Tasks

Creator:: Sanandaji, Anahita
Abstract:: 3D volume segmentation is a fundamental process in many scientific and medical applications. Producing accurate segmentations, in an efficient way, is challenging, in part due to low imaging data quality (e.g., noise and low image resolution), and ambiguity in the data that can only be resolved with higher-level knowledge of...

Computational Rationalizations of Mechanism and Stereocontrol in Small-Molecule Lewis Base Organocatalysis

Creator:: McCauley-Walden, Daniel W.
Abstract:: My work has focused on investigating synthetic organic reactions using applied computational methods. Non-covalent interactions are critical to catalysis, mechanism, and stereoselectivity, with the most prominent interaction for isothioureas being the S···O contact between the catalyst sulfur atom and the oxygen of the acyl group. A comprehensive joint experimental and...

Identification of Endogenous and Exogenous Pararetroviruses in Red Raspberry (Rubus idaeus L.) and Blueberry (Vaccinium corymbosum L.)

Creator:: Diaz Lara, Alfredo
Abstract:: The Pacific Northwest (Oregon and Washington in the United States and British Columbia in Canada) is one of the major producers of red raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) in the world. The expansion of growing area with these crops has resulted in the emergence of new...

Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

Creator:: Creason, Allison L.
Abstract:: Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

The density signature

Creator:: Migler-VonDollen, Theresa
Abstract:: In real networks, identifying dense regions is of great importance. For example, in a network that represents academic collaboration, authors within the densest component of the graph tend to be the most prolific. Dense subgraphs often identify communities in social networks. And dense subgraphs can be used to discover regulatory...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
