Slow-Light Fourier Transform Interferometer, Zhimin Shi, Robert W. Boyd, Ryan M. Camacho, Praveen K. Vudyasetu, John C. Howell

Mathematics, Physics, and Computer Science Faculty Articles and Research

We describe a new type of Fourier transform (FT) interferometer in which the tunable optical delay between the two arms is realized by using a continuously variable slow-light medium instead of a moving arm as in a conventional setup. The spectral resolution of such a FT interferometer exceeds that of a conventional setup of comparable size by a factor equal to the maximum group index of the slow-light medium. The scheme is experimentally demonstrated by using a rubidium atomic vapor cell as the tunable slow-light medium, and the spectral resolution is enhanced by a factor of approximately 100.

A Corpus-Based Approach To Determining Standard American English, Delys Ann Waite Snyder

Theses and Dissertations

Many teachers, test designers, textbook writers, and instructional designers turn to books written by usage experts to determine what is correct standard written American English. Unfortunately, though, experts often disagree about what is correct and what is incorrect, and this disagreement can create problems with validity when people create and assess instruction about usage. One way to discover the rules of standard English usage is to describe what writers actually do in printed, edited English. Researchers can access large collections of standard English through digital text archives, which can be searched electronically. The text archives for this study were taken …

A Developmental Cycle Masks Output From The Circadian Oscillator Under Conditions Of Choline Deficiency In Neurospora, Mi Shi, Luis F. Larrondo, Jennifer J. Loros, Jay C. Dunlap

Dartmouth Scholarship

In Neurospora, metabolic oscillators coexist with the circadian transcriptional/translational feedback loop governed by the FRQ (Frequency) and WC (White Collar) proteins. One of these, a choline deficiency oscillator (CDO) observed in chol-1 mutants grown under choline starvation, drives an uncompensated long-period developmental cycle ( approximately 60-120 h). To assess possible contributions of this metabolic oscillator to the circadian system, molecular and physiological rhythms were followed in liquid culture under choline starvation, but these only confirmed that an oscillator with a normal circadian period length can run under choline starvation. This finding suggested that long-period developmental cycles elicited by nutritional stress …

Long-Term Evolution Of Massive Black Hole Binaries. Iii. Binary Evolution In Collisional Nuclei, David Merritt, Seppo Mikkola, Andras Szell

Articles

In galactic nuclei with sufficiently short relaxation times, binary supermassive black holes can evolve beyond their stalling radii via continued interaction with stars. We study this “collisional” evolutionary regime using both fully self-consistent N-body integrations and approximate Fokker-Planck models. The N-body integrations employ particle numbers up to 0.26×106 and a direct-summation potential solver; close interactions involving the binary are treated using a new implementation of the Mikkola-Aarseth chain regularization algorithm. Even at these large values of N, two-body scattering occurs at high enough rates in the N-body simulations that the binary is never fully in the diffusively-repopulated (i.e. large-N) loss …

Constructed Wetlands For The Landscape Nursery Industry: Nutrient Assimilation And Removal, Sarah White

All Dissertations

Runoff from nursery operations is considered a potential non-point source contamination. Water quality and quantity are quickly becoming important factors that drive management practices at these facilities. Constructed wetland systems (CWS) are a management tool that can be used by nursery operations to improve water quality both for recycling within nursery production areas and for eventual release from nursery production areas into surrounding surface waters. The overall goal of this research was to optimize nutrient removal efficiencies in CWS. To accomplish this goal, I characterized the following: (1) the P sorption and desorption capacity of several substrates; (2) the effect …

A Breakdown In Boundaries: As Explored Through Abjection And The Language Of Abstract Art, Mary Hanley

All Theses

ABSTRACT
My work places emphasis on the anxiety and allure felt at the possibility of ingesting an object belonging to or displaced from the body through the language of abstract art. It links the fears and fascinations felt in situations of perceived abnormality and bodily aggression, to the objectification, or conversely abjection, of objects through images. I investigate a collapse in division between what the perceived identity of a thing or person is, and what it is not.
Each painting rejects an ideal of beauty as portrayed through stability, clarity, and compartmentalization, and embraces beauty as the interconnectedness of opposing …

Yearbooks As A Genre: A Case Study, Melissa Caudill

All Theses

ABSTRACT
In the United States, high school and college yearbooks are extraordinarily well known as a genre, yet they are largely unstudied. Yearbooks preserve images, stories, and facts from each year for one specific group of people, linked by age and geographic community. Yearbook production is a significant commercial enterprise, yet it involves novice writers, editors, and designers. Blending elements of craft, tradition, business, and media, yearbooks as a distinctive genre bear closer rhetorical study and application of professional communication theories.
This historical case study of production practices for a particular college yearbook positions yearbooks rhetorically as texts and sites …

Mixed Convective Heat Transfer And Evaporation At The Air-Water Interface, Prasad Gokhale

All Theses

Functional forms for mixed convective heat transfer and evaporation from an air-water interface were obtained. To obtain these functions, heat transfer and evaporation rates from the air-water interface of an evaporating body of water were quantified in a wind/water tunnel in the presence of an oleyl alcohol monolayer on the water surface. The Nusselt (Nu) and Sherwood (Sh) numbers, parameterizing the dimensionless heat and mass transfer respectively, for transport from the water bulk to air were expressed as functions of the air side Rayleigh (Ra) and Reynolds (Re) numbers. The Nu and Sh were calculated for a range of Ra …

Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park

All Dissertations

Beginning with the development of an embryo and throughout one's adult life angiogenesis plays an essential role for organ growth and repair. The balancing of pro-angiogenic factors to anti-angiogenic factors is what regulates the process of angiogenesis. When this balance is disrupted in one direction or the other, numerous disorders can occur including ocular and inflammatory diseases and, in particular, tumor growth and metastasis. Therefore, inhibition of angiogenesis has become an effective therapy for arresting the growth of tumors.
A key regulator of angiogenesis involves vascular endothelial growth factor (VEGF) and its receptor, VEGFR-2 (KDR). The binding of VEGF to …

Development Of Fullerene Based Sturctures For Photovoltaic And Electronic Applications, Amit Palkar

All Dissertations

Solar energy can be envisioned as a long term alternative to rapidly depleting fossil fuels. The energy from the sun can be harnessed by constructing donor-acceptor (D-A) type devices where the incident photon induces the transfer of an electron from the donor to the acceptor. If recombination is prevented, this electron can then be channeled through an external circuit, thus leading to the generation of photocurrent. Porphyrins, which are the naturally occurring pigments in photosynthesis, have been widely established as donors while fullerenes, such as C₆₀ and C₇₀ , due to their unique electron accepting properties, have been …

Porcine Intestinal Epithelial Cell Lines As A New In Vitro Model For Studying Adherence And Pathogenesis Of Enterotoxigenic Escherichia Coli, Seung Y. Koh, Sajan George, Volker Brozel, Rodney A. Moxley, David H. Francis, Radhey Kaushik

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) infections result in large economic losses in the swine industry worldwide. The organism causes diarrhea by adhering to and colonizing enterocytes in the small intestines. While much progress has been made in understanding the pathogenesis of ETEC, no homologous intestinal epithelial cultures suitable for studying porcine ETEC pathogenesis have been described prior to this report. In the current study, we investigated the adherence of various porcine ETEC strains to two porcine (IPEC-1 and IPEC-J2) and one human (INT-407) small intestinal epithelial cell lines. Each cell line was assessed for its ability to support the adherence of …
