Deep pressure therapy (DPT) is a method of anxiety relief that uses pressure sensations to lower the stress response produced in the brain, and functions in a manner similar to a hug. Heavily weighted blankets and weighted vests are most commonly used to apply DPT, though recent work has shown...
The prevalence of addiction in society has called researchers, educators, policy makers, and clinicians to examine and research causes and treatment approaches to address the manifold problems addictions present individuals and society alike. There are many theoretical approaches to understanding addiction and the behavior change processes that lead from addiction...
Pinot noir has a reputation for lower color stability than other red wine varieties. Because it has relatively low anthocyanin and phenolic content and lacks acylated anthocyanin pigments compared to other red vinifera varieties, color extraction and stability are particularly important. Varying the processing during fermentation of red wine can...

As human-robot interaction becomes more commonplace, roboticists should understand how robot behaviors are perceived by people to avoid misunderstandings. In our lab, we are exploring the use of a Cozmo as an interactive, break-taking aid in workplace settings. Before our interactive aid can be released into the wild, we must...
With robots becoming increasingly commonplace in today’s society, we need to find ways to help robots to become better accepted. One common method used to gain acceptance and build rapport is through the use of humor. Currently, research in robot comedy exists, albeit it is fairly limited. Our goal with...
Relative to visual and audible communication, haptic perception is quiet, does not require eye contact, can be applied at any point on the human body, and can function in parallel with the other four human senses. Vibrotactile feedback is a method of haptic communication using vibrations applied to the skin....
Social robots benefit from a sense of humor, which requires the ability to recognize and adapt to human responses during playful interactions. Past work on humorous robots has classified audience responses with audio-based and preliminary visual-based methods following the joke punchline. Building on this progress, we conducted a survey of...
This thesis describes the implementation of ultrasonic sensors to trigger a stimulus to increase peer interaction for children with disabilities using modified ride-on-cars for mobility.

The aryl hydrocarbon receptor (AhR) has recently been described as a novel therapeutic target, given the potent suppression of multiple immune-mediated diseases following activation by the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In the parent-into-F1 graft-versus-host (GVH) model, suppression of the cytotoxic T-lymphocyte (CTL) response is associated with the presence of CD25⁺CTLA-4⁺IL-10⁺Foxp3[superscript...
The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...

While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
Hybrid programs can often be a desirable option for students entering a graduate program in counseling. However, the rigor of such programs, including academic challenges and maintaining personal wellness, could be a barrier to students from marginalized social locations. Additional support through a hybrid orientation might help these students address...
The symbiosis between cnidarians (e.g., corals or sea anemones) and intracellular dinoflagellate algae of the genus Symbiodinium is of immense ecological importance. In particular, this symbiosis promotes the growth and survival of reef corals in nutrient-poor tropical waters; indeed, coral reefs could not exist without this symbiosis. However, our fundamental...
BACKGROUND: Cell lineage-specific DNA methylation patterns distinguish normal human leukocyte subsets and can

A time-domain model was developed to predict the fluid/structure
interaction of a three-dimensional deformable body in a fluid domain subject to
long-crested finite amplitude waves. These nonlinear waves induce transient
motion in the body. In turn, the interaction of the body with the waves modifies
the wave field, causing additional...
Clostridium perfringens type A is a common source of food poisoning (FP) and non-food-borne (NFB) gastrointestinal diseases in humans. In the intestinal tract, the vegetative cells sporulate and produce a major pathogenic factor, C. perfringens enterotoxin (CPE). Most type A FP isolates carry a chromosomal cpe gene, whereas NFB type...
In normal human cells, oncogene-induced senescence (OIS) depends on induction of DNA damage response (DDR). Oxidative stress and hyper-replication of genomic DNA have been proposed as major causes of DNA damage in OIS cells. Here we report that down-regulation of deoxyribonucleoside pools is another endogenous source of DNA damage in...
