Glioblastoma is a malignant brain tumor that has extremely poor prognoses with a 5 year survival rate of less than 5%. The low survival rates of glioblastoma patients is attributed to glioblastoma cells being extremely resistant to radiotherapy and chemotherapy as well as being very invasive. We previously identified calpain...
Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...
Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...
Antimicrobial coatings used to reduce the risk of infection caused by tissue-contacting medical devices must address specific biocompatibility requirements including prevention of thrombosis and rise of bacterial resistance. An antimicrobial-loaded poly(ethylene-oxide) (PEO) coating has been tentatively shown to be non-fouling with sustained antimicrobial activity. However, the presence of the antimicrobial,...
This internship project (Dr. Dawn Wright—Department of Geoscience) was a synthesis of several aspects of the research process. The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...
Ceratonova shasta is a myxozoan fish parasite that impacts hatchery and wild populations of salmon and trout in the Pacific Northwest. Levels of the parasite in river water can be effectively monitored through direct filtration of parasite spores from water, extraction of total "environmental DNA" (eDNA), then quantitative polymerase chain...
Aluminum alloys are popular in aerospace and automotive industries because of their relatively high strength-to-weight ratio. The study of enhancing aluminum’s mechanical properties through grain refinement is especially important. One such technique is High-Pressure Torsion processing (HPT), which leads to significant grain size refinement and enhances mechanical properties like ductility...
In liquid sodium environments like those proposed for next-generation sodium fast reactors (SFRs), the presence of impurities in the sodium, particularly chemical species containing oxygen, can lead to increased corrosion on sodium-wetted components. It is important to monitor oxygen concentration in the sodium melt, but temperatures of 500 ℃ and...
This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...
This paper seeks to provide a practical answer to the following question: why create a board of directors in a family business? To achieve this, it summarizes the existing research published in the field of family business governance that directly addresses the beneficial role of the board of directors in...
