- Description:
- In multiatomic systems, high applied pressures reduce interatomic contact distances. At pressures comparable to those inside planets, this relatively simple principle completely changes the guiding principles of chemistry and physics established at near-ambient conditions. High-pressure investigations of precisely how the laws of nature evolve in the gigapascal and megabar regime...

- Description:
- This dissertation explores two topics in macroeconomics related to aggregation assumptions and microfoundations. Chapters 1 and 2 focus on the representative agent aggregation assumption in the context of open economies, using both an empirical as well as a theoretical approach. Chapter 3 on the other hand, deals with the microfoundations...

- Description:
- Plasmonic metasurfaces are leading the development of next-generation optical devices with unprecedented compactness and functionality. In contrast to bulk refractive optics, these planar surfaces manipulate light with rationally designed subwavelength building blocks. This thesis focus on how emerging materials and design methods advance the eld of metasurfaces. Chapter 1 reviews...

- Description:
- Chromatin, a complex nuclear structure comprised of DNA, histones, RNA, and other nuclear proteins, is one of the most critical components within the cell because it houses the genetic information and its organization regulates important cellular functions, such as transcription, replication, and repair. Its structural organization is well understood at...

- Description:
- The brain is known to shrink in normal aging or neurodegenerative disease and yet the neurobiological underpinnings of the cortical atrophy remain elusive. The structural changes that represent cortical atrophy can be measured during life using the reliable and quantitative method known as magnetic resonance imaging (MRI). Primary progressive aphasia...
