- Description:
- Second harmonic generation (SHG), a nonlinear optical tool, was used to characterize DNA bound through a chemical linker to the flat surface of a hemispherical lens. Contact angle measurements were used to guarantee that the chemical linker did not hydrolyze under experimental conditions. SHG experiments followed the effects of salt...

- Description:
- The first chapter of this dissertation investigates the pricing of systematic variance risk in the equity options market.

Furthermore, we show that a class of linear factor models cannot simultaneously explain index...

- Description:
- This study investigates the causes and welfare consequences of unravelling in two-sided matching markets. "Unravelling" arises when agents contract with one another at an early stage, before much of the relevant information is available. Such early matches may lead to ex-post inefficiencies and are perceived as socially harmful. This study...

- Description:
- Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...

- Description:

- Description:
- A comprehensive understanding of how image processing occurs in the primary visual cortex (V1) requires learning what aspects of neuronal responses are driven by strong feed-forward input from the lateral geniculate nucleus (LGN), and what aspects arise due to the densely recurrent network operating within the cortex itself. From an...

I first demonstrate that children as young as age three distinguish between relative (e.g., 'big', 'long'), maximum standard absolute (e.g.,...
