A stroke occurs when blood flow in the brain is impaired and often causes damage to corticospinal tract projections that control the muscles of the upper-extremity. Due to this damage, 50-70% of stroke survivors experience long-term upper-extremity functional deficits(Faria-Fortini, Michaelsen, Cassiano, & Teixeira-Salmela, 2011). These deficits result from motor impairments...
This dissertation investigates long-term biographies of seventeen small medieval settlements in the region of Hegranes, Skagafjörður, North Iceland, placing their creation, development, and reuse in the context of coupled social and environmental change. The individuals and households who lived at the Hegranes sites were at the nexus of both kinds...
Data mining is multidisciplinary process involving computer science, artificial intelli- gence, and machine learning. The aim of data mining is discovering knowledge from a vast amount of data. This process consists of a set of stages forming a pipeline. This pipeline process consists of multiple steps: 1) Finding the right...
Hybrid pixel detectors, comprising of pixelated sensors coupled to readout integrated circuits (ROICs) with complex in-pixel processing, are essential for many of today’s scientific instruments and imaging systems. Large-area detectors are required in a variety of systems: from detectors for synchrotron beamlines to telescopes for astronomy, which range from a...
This dissertation contains four essays. The first essay, Strategically Giving Service: The Effect of Real-Time Information on Service Efficiency, analyzes the impact of the increased availability of real-time information on the behavior of strategic agents and the implications of this phenomenon for service efficiency using data from one of the...
Localized corrosion involves the selective attack of a metal at a small, exposed site. This can be particularly devastating for load-bearing structures like bridges, which can fail catastrophically even with very little material loss. Unfortunately, such corrosion is very hard to prevent, predict, and detect. Corrosion can be prevented by...
Records of temperature and precipitation during Quaternary interglacial periods on Greenland are notably scarce, limiting assessment of the magnitude and rate of local environmental response to orbitally-driven Arctic warming. It is largely unknown if warming across Greenland was spatially uniform through past interglacials, and if warming was accompanied by major...
In solar energy conversion ranging from artificial photosynthesis to photocatalysis, transition metal complexes (TMC) are essential building blocks due to several attractive properties: intense absorption within the solar spectrum, presence of charge-transfer excited state, and substrate binding capability through coordination geometry changes. In order to gain insight into controlling solar...
Proteins represent a critical class of biomolecules, universally employed by all living organisms to fulfill essential structural, functional, and enzymatic roles necessary to support life. In nature, these polymers are composed generally of twenty natural amino acid (AA) building blocks, which can be modified with covalent adducts known as post-translational...
This dissertation researches the Cenomanian, Turonian, and Coniacian Stages (100.5 - 86.3 Ma) of the Cretaceous Period, a geologic interval of interest due to its extreme global warmth, iconic faunas, and oceanic anoxic events (OAEs). Five globally dispersed geochemical and stratigraphic case studies reconstruct interactions of the mid-Cretaceous carbon cycle...
