- Description:
- In this thesis, we discuss classical and recent results around the damped wave equation on compact and noncompact manifolds. We firstly show that on asymptotically cylindrical and conic manifolds, the geometric control condition and the network control condition give exponential and logarithmic decay rates respectively. We then show that a...

- Description:
- Stimulation of the cGAS-STING (cycle GMP-AMP synthase-Stimulator of Interferon Genes) pathway increases T cell activation and tracking into the tumor and reverses the immunosuppressive phenotype of myeloid cells. Direct targeting of the STING receptor using synthetic cyclic dinucleotide (CDN) ligands represents an attractive immunotherapeutic strategy for the treatment of lymphocyte-depleted...

- Description:
- Political theorists generally ascribe to the state a decisive role in the formation and protection of property rights, a view especially prevalent in the historiography of financial property in the United States. Given the capacities of government at the American Founding, however, such accounts are implausible. Drawing on writings composed...

- Description:
- Recent developments have enabled L12-strengthened Co-based superalloys, which have thepotential to surpass Ni-based superalloys as the material of choice for the hottest sections of turbine blades due to cobalt’s 40 ºC higher melting point. The most-studied branch of Co-based superalloys are based on the L12 phase Co3(Al,W); however, there is...

- Description:
- Caught between world wars and Stalin’s consolidation of power, citizens of Soviet Russia of the 1920s and 1930s had little to laugh about. Yet a unique tendency toward disruptive humor surfaces in poetry and prose over these two decades. I explore disruptive humor in select longer poetry of Nikolai Zabolotsky,...

- Description:
- This dissertation consists of three chapters about education policies in developing countries. The first chapter examines two extrapolation approaches to make out-of-sample predictions using cash transfer experiments in Malawi and Morocco. The second chapter evaluates India's workfare program in terms of targeting efficiency and effects on school enrollment, in comparison...

- Description:
- We present both semiclassical asymptotics for the wave equation on a stationary Kaluza-Klein spacetime and an index theorem describing the difference of the positive-frequency spectral projectors for two stationary regions in a globally hyperbolic spacetime. The first result involves analyzing the restrictions of the wave trace to isotypic subspaces for...

- Chapter 1 investigates asks the question how do financial frictions affect the type of human capital investments that students make in college? To study this question, I build a novel dataset covering more than 700,000 U.S. students, merging commencement records with address histories, credit bureau records, and professional resumes. I...
