Many estimation and inference procedures rely on asymptotic approximations for quantities that are unknown to researchers. While often convenient, such approximations can be poor in practice, even when the number of observations is ostensibly large. One response is to eschew asymptotics in favor of finite sample bounds. While remarkable progress...
Conventionally cross-linked polymers, which comprise the vast majority of commercial thermosets, cannot be decross-linked after curing or flow upon heating. Therefore, they cannot be effectively recycled into high-value products at end-of-life. Their lack of recyclability is due to the permanent cross-links, which restrict the flow of the chains in the...
Popular histories of United States mass incarceration often focus on federal wars on crime, law and order policing, and the passage of harsh sentencing laws to explain how the United States transformed into the world’s leader in incarceration. My dissertation on the crisis of state prison overcrowding and prisoner resistance...
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...
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...
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...
This dissertation focuses on two topics in international macroeconomics: the identification of the international spillovers of US interest rate shocks, and the study of its main transmission channels. In Chapter 1, I present the Spillover Puzzle of US Monetary Policy - the fact that in response to a US interest...
Astronomy has entered a “multimessenger” era: one that combines electromagnetic “sight” with gravitational “touch.” This dissertation serves as a roadmap of the multimessenger frontier, to join the littered environments of dead and dying starswith their unclear origins. To uncover stars’ innermost secrets, we explore rare, transient glimpses into single, double,...
Bio-integrated electronics with advanced monitoring capabilities have garnered considerable interest as a means of expanding patient care beyond traditional hospital and clinic settings. These mechanically soft microsystems, many of which are bioresorbable and wireless, have the potential to replace bulky, rigid, and wired medical technologies by matching or exceeding their...
Every day, we communicate through computers on projects ranging from a group lunch order to booking a flight to learning critical medical information. And every day, we also miscommunicate through computers: We don’t pick up on an intentionally humorous response, or we miss the criticality of a request. This is...
