- Description:
- The viscoelastic properties of microbial biofilms have attracted great interests in recent years due to the ubiquity of biofilms and their wide range of industrial and municipal applications causing tremendous societal impacts. Biofilms are predominantly architected by extracellular polymeric substances (EPS) matrices composed of bacterial cells and biopolymers secreted by...

- Description:
- In this dissertation, we study models and methods to address uncertainties that can vary in optimization problems. Robust optimization is a popular approach for optimization under uncertainty, especially if limited information is available about the distribution of the uncertainty. It models the uncertainty through sets and finds a robust optimal...

- Description:
- Mineral inclusions in diamond, brought to the surface through kimberlitic eruptions, provide a unique glimpse into the geochemical inner workings of Earth’s deep interior. Diamonds source a wide range of depths in the mantle. While most diamonds originate from the upper 200 km of the Earth’s mantle, aptly called super-deep...

- Description:
- Episodic memory provides a means by which we reflect on the past, make decisions about the future, and form a learned identity. Episodic memory depends on the hippocampus as well as on the distributed set of regions that form a hippocampal-cortical network (HCN), including medial prefrontal, posterior cingulate, and medial...

- Description:
- Dilute Al-Sc-Zr-Si-based aluminum alloys retain their strength for long periods of time at elevated temperatures due to a dispersion of nanometric, coherent, and coarsening-resistant Al3(Sc,Zr) (L12 structure) nanoprecipitates that are formed upon aging. These alloys are attractive for replacement of dense steels and costly Ti alloys in the 250–400 °C...

- Description:
- In susceptible individuals, episodic memories of overwhelmingly stressful experiences can give rise to debilitating socio-affective symptoms, including social dysfunction. This occurs even when such memories are not easily accessed for retrieval. In this case, it is generally accepted that the restricted retrieval of such memories is due to their having...

- Description:
- The hippocampus has been identified as a critical structure for supporting spatial memory processes in both humans and animals alike. Many of these processes such as the ability to self-localize in a given environment as well as engage in goal-directed navigation are thought to depend on the location-specific firing of...
