Radiation-driven, geometrically thick, dusty obscuration in active galactic nuclei
(Johns Hopkins UniversityUSA, 2016-10-05)Substantial evidence points to dusty, geometrically thick tori obscuring the central engines of active galactic nuclei (AGNs), but so far no mechanism satisfactorily explains why cool dust in the torus remains in a puffy ... -
Raman spectroscopy of isogenic breast cancer cells derived from organ-specific metastases reveals distinct biochemical signatures
(2015-05-01)Characterizing the subtle divergence of the metastatic lesions from the primary tumor is critical to understanding organ-specific adaptations that regulate further disease progression as well as the development of targeted ... -
RANDOM DOT PRODUCT GRAPHS A MODEL FOR SOCIAL NETWORKS
(2008-02-01)We develop a new set of random graph models. The motivation for these mod- els comes from social networks and is based on the idea of common interest. We represent a social network as a graph, in which vertices correspond ... -
RANDOM DRIFT: CHANCE AND EXPLANATION IN EVOLUTIONARY BIOLOGY
(2006-08-03)The central claim for which I argue in this dissertation is that there are important phenomena that occur by random drift that evolutionary biologists explain using a strategy I term “process explanation.” This claim ... -
Random Graph Modeling and Discovery
(Johns Hopkins UniversityUSA, 2015-10-16)In the first part of this thesis, we present a general class of models for random graphs that is applicable to a broad range of problems, including those in which graphs have complicated edge structures. These models need ... -
RATIONAL IDEALOGUES OR ORTHODOX FANATICS? DISCERNING IDEOLOGY’S ROLE IN TERRORIST ORGANIZATION BEHAVIOR
(2015-01-28)There have long been divergent perceptions among scholars and policymakers regarding the relevance of a terrorist organization’s ideology to its actual decision making process. Some observers believe that terrorist ... -
RBM24 IS ESSENTIAL FOR NORMAL EARLY EMBRYONIC DEVELOPENT
(2014-02-12)Rbm24 was recently identified as a gene expressed during early mouse cardiac development (Miller et al., 2008). Due to its tightly restricted and persistent expression from formation of the cardiac crescent onwards and ... -

(2014-12-23)Background: As mobile phone ownership levels grow globally, opportunities to target hard-to-reach populations through mobile-health technologies become more realistic. In a rural Kenyan population, this dissertation seeks ... -
Real Johnson-Wilson Theories and Computations
(Johns Hopkins UniversityUSA, 2016-03-22)Our main result is a computation of ER(n)^*(CP^\infty), the Real Johnson-Wilson cohomology of CP^\infty, for all n. We apply techniques from equivariant stable homotopy theory to the Bockstein spectral sequence. We produce ... -
Realist Constructivism: Understanding Foreign Policy Intent
(2014-09-18)International Relations theory is a guide for understanding state behavior, which is especially important when dealing with potentially threatening countries whose intentions are difficult to decipher due to a perceived ... -
