(2019-04-19)
Asphaltene precipitation and subsequent deposition is a growing problem for the oil and gas industry. The so-called “cholesterol of the oil” is the heaviest and the most polar fraction of the oil that is well-known to cause ...
• #### Engineering Adeno-Associated Virus for Protease Targeted Gene Therapy and Immune Avoidance ﻿

(2019-04-19)
Adeno-associated virus (AAV) has earned significant attention as a safe and efficient gene therapy tool. AAV has been used in over 100 clinical trials to treat a variety of human diseases. However, non-specific targeting ...
• #### Getting by with a Little Help from (Family and) Friends?: The Link between Family Support and Residential Attainment ﻿

(2019-04-18)
In the context of increasing wealth inequality and work insecurity, the burdens of economic instability have been overwhelmingly offloaded onto American families. This instability and exposure to disadvantage represents a ...
• #### Development of Low-Cost Technologies for Cervical Cancer Prevention in Low-Resource Settings ﻿

(2019-04-19)
Cervical cancer is a preventable disease. Early detection and treatment strategies have reduced the rate of cervical cancer by 65% in high-income countries. However, cervical cancer remains the first or second leading ...
• #### Resolving Spatial Heterogeneity of Elastic Properties in Veins and Mitral Valves ﻿

(2019-04-19)
Each tissue of the cardiovascular system exhibits a unique pattern of composition and material properties, which are matched to the tissue’s mechanical environment and required function. My global objective was to characterize ...

• #### The Variability of Strains in Bolts and the Effect on Preload in Jointed Structure ﻿

(2019-04-19)
Torque wrenches are the most common method used for tightening bolts; however, this method can cause a large amount of uncertainty in the resulting bolt preload. With the inability to determine the preload in bolted ...
• #### Hardware, wetware, and methods for precision control of gene expression ﻿

(2019-04-17)
The ability to control the biochemical processes of the cell is fundamental to the goals of synthetic biology. This control implies the ability to specify the spatial, temporal, and amount of gene expression and protein ...
