Given any polyhedron in R3, we can cut it open along its edges, flatten it out, and obtain a polygon in the plane R2. In this project, we explored the opposite process, an open question that was first posed about 70 years ago: given a polygon in R2, what is...
Anxiety disorders are the most common group of mental illnesses in the United States and affect over 15% of the population. Prior work utilizing electroencephalogram (EEG) to investigate event-related potentials (ERPs) from the scalp has shown success in isolating certain neural correlates related to increased risk for developing anxiety disorders....
Posttraumatic stress disorder (PTSD) is an anxiety disorder characterized by flashbacks of the traumatic event and high comorbidity with major depressive disorder (MDD). Prior stress is known to increase the likelihood of developing PTSD after experiencing a traumatic event. Currently, PTSD is diagnosed clinically, its biological etiology is not known...
Expanding on research done on the mental health and happiness benefits associated with romantic relationships, this study investigates whether identity denial, the experience of being socially denied one’s chosen identity by having others refuse to acknowledge that identity, presents a challenge for bisexual people within committed romantic relationships. For straight,...
Physiological linkage (i.e., the covariation of moment-to-moment physiology between individuals) is thought to play an important role in relationship functioning. The present study examined physiological linkage across interbeat interval (IBI) and skin conductance levels (SCL) in a sample of married spouses (N=106) during both a pleasant and a conflict conversation...
Skeletal sexual dimorphism presents itself in humans primarily through the anatomical shape of the cranium and pelvis. However, some physical anthropologists maintain that climate could have an effect on human sexual dimorphism. Despite ongoing research pertaining to climatic effects on soft tissue or size dimorphism, little to no research has...
A survey of adults (n = 706) found low levels of awareness of two social movements aimed at decreasing weight stigma: the Fat Acceptance Movement and Health at Every Size movement. For HAES, providing a brief story of an overweight person who endorses HAES improved perceptions of the movement.
According to Lisjak, Lee, and Gardner (2012), a threat to a brand can elicit the same response as a threat to the self. The current research examined whether people react differently to brand threats as a function of East Asian versus North American culture and as a function of whether...
The High Energy Density Sciences group at SLAC National Accelerator Laboratory studies materials in extreme conditions such as very high temperatures and pressures. We use shock waves produced by the Linac Coherent Light Source to compress polycrystalline diamond samples. Compressing these samples allows us to use x-ray diffraction to study...
Approximately 1 in 3 deaths in the US is caused by cardiovascular diseases, among them atherosclerosis. Atherosclerosis occurs through excessive cholesterol deposition (hyperlipidemia) along the inner layer of the artery called the intima, resulting in plaque formation that blocks arterial blood flow and could lead to heart attacks and strokes....
