In a review of published lncRNA subcellular localization classifiers, we show that the commonly used validation protocol generates optimistic performance measures, and …

Exploring Crystal Polymorphism In Additive-Assisted Chemical Vapor-Deposited Transition Metal Chalcogenides And Oxides, Lawrence Kirimi Mubwika

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crystal polymorphism is a phenomenon in which compounds with the same chemical formula can be crystallized into different crystal structures. This phenomenon can be observed in elemental materials, such as diamond and graphite, as well as in compounds, such as the trigonal (1H) or octahedral (1T) prismatic MoS₂. Crystals can also exhibit polytypism by stacking different polymorphs in a certain order, with the stacking sequence determining the variation between polytypes. Although all polymorphs and polytypes have the same chemical composition, each polymorph and polytype possesses unique electronic and physical properties.

This study explores the additive-assisted chemical vapor deposition …

Advances In Machine Learning Aided Seismic Interpretation And Inversion For Subsurface Characterization, Tobi Micheal Ore

Graduate Theses, Dissertations, and Problem Reports (ETD)

Geophysical data are used to “remotely sense” the subsurface to illuminate structures, stratigraphy, and features that are of interest in the exploration for energy, suitable storage for carbon dioxide, geothermal development, and environmental considerations. The interpretations of these data typically are regarded as partially an art, as it depends on the experience of the interpreter. This is further exacerbated with the big data era as this data is large and takes several days, even longer, to manually interpret. To bridge this gap of speed and subjective bias, machine learning has been successfully applied to automate the geophysical interpretation process. This …

Making Something Out Of Nothing: Immobility As An Operant, KaʻAla K. Bajo

Graduate Theses, Dissertations, and Problem Reports (ETD)

The tradition of research in the experimental analysis of behavior generally emphasizes the analysis of overt, discrete responses such as lever presses or key pecks. Reflecting this emphasis, definitions of behavior involve the observable action or movement of an organism through space. Although continuous responses involving little to no movement, such as “holding still” or “immobility”, fall outside these definitions, immobility is a form of continuous, operant responding that can be learned and experimentally controlled. Three experiments were conducted to investigate parameters surrounding immobility as an operant. In Experiment 1, immobility in the form of platform-standing bouts was shaped and …

Evaluating The Efficacy Of The Archaeal Proteasome To Alleviate Protein-Misfolding Retinopathy, Celine Brooks

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nearly all neurodegenerative diseases (NDs) and some eye diseases are characterized by the presence of misfolded and aggregated proteins. The ubiquitin proteasome system (UPS) is responsible for degrading the majority of proteins including misfolded and aggregated proteins. However, in NDs the performance of the UPS is impaired, and this impairment partially comes from these protein aggregates inhibiting the proteasome. This inhibition leads to an accumulation of protein aggregates, more proteasomal inhibition, and fewer chaperones for newly synthesized proteins, triggering a collapse in proteostasis, which is thought to contribute to the pathogenesis of NDs. Consequently, stimulating proteasome function is being investigated …

Policy Dynamics In Young Democracies: Attention, Electoral Change, And Responsiveness In Ghana And South Africa, Christiana Bugri

Triggered Online System Re-Identification Applied To Model Predictive Control Using Gaussian Processes, Daniel Augusto Kestering

Graduate Theses, Dissertations, and Problem Reports (ETD)

Safety, product quality, enhanced performance, and increased profit all depend on the control of chemical and energy processes. However, operational issues can lead to control challenges, especially when processes are subject to disturbances during their operation. Process control methods work best when processes operate close to their designed operat- ing conditions, but lack of performance or other issues may occur when the process is far from such conditions. To overcome these challenges, in this dissertation, online model re- identification is proposed for Model Predictive Control (MPC). This involves reassessing the predictive model of an advanced controller, namely MPC, when re-identification …
