iii Abstract In early 2010, the Long-Baseline Neutrino Experiment (LBNE) science collaboration initiated a study to investigate the physics potential of the experiment with a broad set of different beam, near-and far-detector configurations. Nine initial topics were identified as scientific areas that motivate construction of a long-baseline neutrino… (More)
Crack growth in a low constraint plane strain environment exists in many structures such as penetrating cracks in a pressure vessel. A new fracture mechanics specimen, the back-bend specimen, has been developed to study this loading. The back-bend specimen gives a low triaxiality, plane strain test through the use of a three-point or four-point loading,… (More)
Cytocompatible, co-doped cerium oxide nanoparticles exhibited strong upconversion properties that were found to kill lung cancer cells by inducing apoptosis thereby demonstrating the potential to be used as clinical contrast agents for imaging and as therapeutic agents for treatment of cancer.
This paper proposes a simple and practical method to amplify signals for space-multiplexed optical transmission. In this amplification technique, the output facet of the multicore or multimode fiber is mapped back to the same type of fiber after passing through an imaging and bulk amplifying region. Simulations are carried out for a seven-core multi-core… (More)
BACKGROUND Human immunodeficiency virus (HIV) infections are increasing among young men who have sex with men (YMSM), yet few HIV prevention programs have studied this population. Keep It Up! (KIU!), an online HIV prevention program tailored to diverse YMSM, was developed to fill this gap. The KIU! 2.0 randomized controlled trial (RCT) was launched to… (More)
This course is designed for students in science, engineering and math who wish to know something about the " who, how, why, when and where " of physics. It assumes they know something of the " what " of physics in order to be science students. I trace the developments leading to today's physics considering when and where they happened, who took part, what… (More)
In the wet-dry tropics, animal species face the major challenges of acquiring food, water or shelter during an extended dry season. Although large and conspicuous animals such as ungulates and waterfowl migrate to wetter areas during this time, little is known of how smaller and more cryptic animal species with less mobility meet these challenges. We fenced… (More)
Utilization of patient-reported outcome measures (PROs) had been limited by the lack of psychometrically sound measures scored in real-time. The Patient Reported Outcomes Measurement Information System (PROMIS) initiative developed a broad array of high-quality PRO measures. Towards reducing the number of items administered in measuring PROs, PROMIS employs… (More)
