Emotion dysregulation plays a central role in psychopathology (B. Bradley et al., 2011) and has been linked to aberrant activation of neural circuitry involved in emotion regulation (Beauregard, Paquette, & Lévesque, 2006; Etkin & Schatzberg, 2011). In recent years, technological advances in neuroimaging methods coupled with developments in machine learning have allo....

Anger is a pervasive problem after individuals experience traumatic stress that heightens the risk for violence, health problems, poor relationships, and poor treatment outcomes. Previous research has demonstrated a moderate relationship between anger and posttraumatic stress disorder (PTSD), yet this research also highlights that anger has not been rigorously measured ....

Prior research has shown that both emotion recognition and expression in children with Autism Spectrum Disorder (ASD) differs from that of typically developing children, and that these differences may contribute to observed social impairment. This study extends prior research in this area with an integrated examination of both expression and recognition of emotion, and ....

Emerging adults who have Autism Spectrum Disorder (ASD) often encounter difficulties within the university setting. Despite an increase in the number of students with ASD enrolled in postsecondary educational institutions, there are few reports on the social, academic, and/or other needs of college students with ASD. The purpose of this study was to assess the perspecti....

As the demand for ever increasingly powerful machines continues, new architectures are sought to be the next route of breaking past the brick wall that currently stagnates the performance growth of modern multi-core CPUs. Due to physical limitations, scaling single-core performance any further is no longer possible, giving rise to modern multi-cores. However, the brick ....

This thesis is a study of a post-World War II polio epidemic in one small Southwest Virginian town before widespread application of the vaccine. While others have explored urban public health responses to polio and national efforts to promote prevention and treatment efforts, in this history I look at reactions to the disease at the local level in this rural community p....

Cancer progression and physiological changes within the cells are accompanied by alterations in the biophysical properties. Therefore, the cell biophysical properties can serve as promising markers for cancer detection and physiological activities. To aid in the investigation of the biophysical markers of cells, a microfluidic chip has been developed which consists of a....

It has historically been the case that CPUs have run programs ever faster without significant intervention on the behalf of the programmer. However, this "free lunch" has largely ended due to the end of exponentially increasing core frequency and the current slow increase in instruction-level parallelism but continues to a degree in cache size improvements. But since Mo....

With GaN and SiC switching devices becoming more commercially available, higher switching frequency is being applied to achieve higher efficiency and power density in power converters. However, electro-magnetic interference (EMI) becomes a more severe problem as a result. In this thesis, the switching frequency effect on conducted EMI noise is assessed. As EMI noise inc....

Because renewable energy sources are environment-friendly and inexhaustible, more and more renewable energy power plants have been integrated into power grids worldwide. To compensate for their inherent variability, STATCOMs are typically installed at the point of common coupling (PCC) to help their operation by regulating the PCC voltage. However under different contin....

Adoption of new agricultural technologies by farmers in developing countries is sometimes limited, despite the associated benefits. Potato farmers in Carchi, Ecuador rely heavily on pesticides to limit pest and disease damage, rather than adopting a more sustainable and economically viable alternative: Integrated Pest Management (IPM). One reason IPM adoption is limited....

This study reports on the behavior of silica based optical fibers in a hydrogen environment at high temperatures. The hydrogen response in the form of optical loss in the wavelength range of 1000-2500 nm of a germanium doped graded index 50/125 graded index fiber was examined in the temperature range of 20â800 °C. When the fiber was exposed to hydrogen at 800 °C ....
