Duration of El Niño and La Niña events : mechanisms and multiyear predictability
(2020-08-13)El Niño-Southern Oscillation (ENSO) is the dominant mode of interannual climate variability and affects global weather patterns via atmospheric teleconnections. Both warm (El Niño) and cold (La Niña) phases of the ENSO ... -
Biostratigraphy of the Cardenas formation (Upper Cretaceous) San Luis Potosi, Mexico
(1965)The Cardenas Formation is a very fossiliferous 1050-meter thick unit of finely clastic sedimentary rocks that crops out in an asymmetric syncline in the folded Sierra Madre Oriental. Six versions of the stratigraphy at ... -
Volcanic stratigraphy, structural geology, and K-Ar geochronology of the Durango area, Durango, Mexico
(1973)Detailed mapping in the Sierra Madre Occidental, near Durango City, Mexico, has documented more than 700 m of rhyolitic volcanic rock (Río Chico Formation) overlain by basaltic lava-flow rock (Metates Formation). The Río ... -
Seismic imaging of deep mantle plumes and inner-outer core boundary heterogeneity using core waves
(2020-08-13)The large contrast of physical properties across the core-mantle boundary (CMB) results in complicated seismic raypaths that can be used to study the deep earth. In this dissertation, I use core waves to address two ... -
Structural geology of carboniferous rocks near Marble Falls, Burnet County, Texas
(1961)Carboniferous rocks assigned to the Houy, Chappel, Barnett, Marble Falls, and Smithwick formations crop out near Marble Falls, Texas. Numerous northeast-trending normal faults that cut the Paleozoic and Precambrian rocks ... -

Large clutch of Jurassic mammaliamorph perinates and evolution of mammalian reproduction and growth
(2018-05-03)Transformations in morphology, physiology, and behavior along the mammalian stem lineage were accompanied by profound modifications to reproduction and growth, including the emergence of a reproductive strategy characterized ... -
Probabilistic modeling with human factors in machine learning
(2020-09-03)Although machine learning has been a very popular research area, the human factors have been largely unexplored. In this dissertation, we present our work in three directions: (1) models for better understanding human ... -
Investment diversification in natural resources
(1999)Investment diversification is a process of evaluating and selecting an investment portfolio to maximize returns and minimize volatility of returns. The objective of this study is to provide a robust model of investment ... -
Regulation of pre-mRNA splicing by light signal in Arabidopsis thaliana
(2017-09-14)Light signal regulates plant growth and development by controlling a plethora of gene expression changes. Post-transcriptional regulation, especially pre-mRNA processing, is a key step in controlling gene expression; ... -
Taxpayers, not tax-eaters : the problems and pitfalls of talking about poverty
(2020-07-17)Poverty in the United States is defined in a variety of ways by government officials, economists and behavioral scientists, nonprofits and advocates, and political scientists. The issue of poverty is a social problem with ... -
Systematic lithologic characterization of Pleistocene mass-transport deposit, Mississippi Canyon of the Northern Gulf of Mexico, USA
Few publications have attempted lithologic calibration of mass transport deposits, (MTDs), usually in the course of field descriptions. While the principal motivation for further understanding these slope failure deposits ... -
Provenance and geochronological insights into Late Cretaceous-Cenozoic foreland basin development in the Subandean Zone and Oriente Basin of Ecuador
(2018-07-27)The evolution of sediment source regions in the Andes of Ecuador can be linked to Late Cretaceous-Cenozoic development of a subduction-related magmatic arc, retroarc fold-thrust belt, and flexural foreland basin. An ... -
New evidence of regressing and transgressing Jurassic siliciclastic coastlines : Dhruma Formation, northern central Arabia
(2018-06-26)The Middle Jurassic Dhruma carbonates are long known as a major hydrocarbon reservoir with massive proven reserves in Saudi Arabia and other Arabian-Gulf countries. Regional studies indicate that these hydrocarbon-rich ... -
Operating at the intersection of social, engineered, and natural systems : assessing hydrologic impacts of green stormwater infrastructure based on stated rates of adoption
(2020-08-17)Urbanization disrupts natural hydrologic processes, causing increased risks of flooding, higher runoff volumes, and reduced infiltration volumes, among other challenges. Implementing green stormwater infrastructure (GSI) ... -
Resource scheduling and design of real-time Cyber-Physical Systems in the open system environment
(2020-06-25)In this thesis, we consider the problem of resource provisioning and system designs for real-time Cyber-Physical Systems (CPS) in an open system environment. In an open system environment, there does not exist a global ... -
Areal geology of Candelaria area Presidio County, Trans-Pecos Texas
(1956)The extreme northwestern part of the Candelaria area belongs to the Mexican Highland province; its structure is the result of Laramide orogeny. The rest, consisting of northward trending fault blocks and intervening basins ... -
Recognizing, negotiating, & normalizing : college students’ memorable messages of sexual consent
Up to 22% of U.S. college students will experience a sexual assault, with women and gender non-conforming students reporting rates as high as 28% and 38%, respectively (Mellins et al., 2017). Although considerable research ... -
Human capital : survey development, adolescent perceptions and correlates
This study sought to investigate the saliency of Human Capital (HC), a set of six positive assets as contributors to the overall health, well-being and success of an adolescent population. Furthermore, given the mediating ... -
An experimental and analytical method for assessing the integration of electric vehicles into the bulk power system
(2017-01-09)In recent years, several trends are indicating a move towards a very different bulk power system. Increased integration of renewables, energy storage, synchrophasors, microgrids, Internet of Things devices, and electric ...
