Middle And Late Devonian New Albany Shale In The Kentucky Geological Survey Marvin Blan No. 1 Well, Hancock County, Kentucky, Brandon C. Nuttall

Report of Investigations--KGS

A 30-ft section of core was recovered in the Grassy Creek Member of the New Albany Shale in the Kentucky Geological Survey Marvin Blan No. 1 well, Hancock County, Ky. (permit 104925, API No. 16091013960000). Analysis characterized the New Albany Shale as a regional seal for preventing vertical migration of carbon dioxide stored in deeper zones, as a natural gas reservoir, and for its potential for enhanced gas recovery and sequestration of carbon dioxide. A show of natural gas at the top of the New Albany Shale was encountered during drilling. Core was recovered in an aluminum sleeve cut into …

Mexsvms: Mid-Level Features For Scalable Action Recognition, Du Tran, Lorenzo Torresani

Computer Science Technical Reports

This paper introduces MEXSVMs, a mid-level representation enabling efficient recognition of actions in videos. The entries in our descriptor are the outputs of several movement classifiers evaluated over spatial-temporal volumes of the image sequence, using space-time interest points as low-level features. Each movement classifier is a simple exemplar-SVM, i.e., an SVM trained using a single positive video and a large number of negative sequences. Our representation offers two main advantages. First, since our mid-level features are learned from individual video exemplars, they require minimal amount of supervision. Second, we show that even simple linear classification models trained on our global …

Design And Synthesis Of A Potential Chemotherapeutic Agent Using Goniothalamin As A Natural Product Template, Mark F. Mechelke, Addison A. Dumke, Sarah E. Wegwerth

Chemistry Faculty Publications

Goniothalamin, a natural product extracted from the tree bark of the Goniothalamus genus, has been shown to induce apoptosis in cancer cells. It is hypothesized that goniothalamin's biological activity is due to its ability to react with thiols. Goniothalamin has been shown to decrease levels of glutathione, a natural antioxidant, found in cancer cells. This causes a redox imbalance, which ultimately leads to cell death. Thiol-reactive compounds, like goniothalamin, have also been shown to inhibit nuclear factor-κB (NF-κB). NF-κB is a transcription factor that has been implicated in unregulated cell growth. Through a nine step sequence, a novle analogue of …

• Glycol nucleic acid (GNA) is a non-natural analog of DNA
• In place of the deoxyribose unit of DNA, GNA has an acyclic ethylene glycol unit (Fig. 1)
• The differences between DNA and GNA are evident in the duplex structure (Fig. 3)
• Instead of a major and minor groove, GNA has one large groove (Fig. 3)
• The base pairs of GNA wrap around the single groove like a ribbon on a spool (Fig. 3)
• GNA has primarily intra-strand base stacking, with each base stacking on top of a base of the opposite strand, as opposed to the inter-strand base stacking of …

The Use Of Molecular Dynamics To Predict The Stability Of Squaraine Rotaxanes, Ruth Nelson, Jeffrey Baumes, Richard D. Connell, Ivan Murgu, Allen Oliver, Bradley Smith, Andrew Johnson

CUP Undergraduate Research

Squaraine rotaxanes are fluorescent molecules comprised of two parts—a dumbbell-shaped squaraine dye threaded through a ring-shaped macrocycle—that are held together by hydrogen bonding, hydrophobic effects, and the size of the opening in the macrocycle1. Since the squaraine is an extremely electrophilic species3, nucleophilic attack by water is possible when it slips out of the macrocycle. This results in a loss of fluorescence. These near-IR dyes have many applications, including effective labeling of bacterial cells4. Previous studies have shown that the unprotected squaraine dye is unstable, and the adamantyl rotaxane degrades over time while the isophthalamidyl and pyridinyl rotaxanes remain stable2(Fig. …

Mathematical Modelling Of Internal Heat Recovery In Flash Tank Heat Exchanger Cascades, Andrei Korobeinikov, John E. Mccarthy, Emma Mooney, Krum Semkov, James Varghese

Mathematics Faculty Publications

Flash tank evaporation combined with a condensing heat exchanger can be used when heat exchange is required between two streams and where at least one of these streams is difficult to handle (tends severely to scale, foul, causing blockages). To increase the efficiency of heat exchange, a cascade of these units in series can be used. Heat transfer relationships in such a cascade are very complex due to their interconnectivity, thus the impact of any changes proposed is difficult to predict. Moreover, the distribution of loads and driving forces in different stages and the number of designed stages faces tradeoffs …

Do We Need To Analyze Spectra By Hand?, Adam M. Terwilliger, Richard L. Lord

Student Summer Scholars Manuscripts

Computational chemistry uses computer science to explore structures and energies of chemical species. A typical computational chemistry output file contains tens or hundreds of thousands of text lines. Automation makes the analysis of these large data sets increasingly more efficient. In turn, we constructed computer programs using Python that allow us to focus our time upon the chemical interpretation of these results. We used these efficient analyses to study a vanadiumoxo species synthesized by our collaborators. Our calculations answer many questions about the redox states in these compounds, though they predict that the experimental crystal structure may not reveal all …

Role Of Resonance-Enhanced Multiphoton Excitation In High-Harmonic Generation Of N-2: A Time-Dependent Density-Functional-Theory Study, Xi Chu, Gerrit C. Groenenboom

Chemistry and Biochemistry Faculty Publications

A minimum at similar to 39 eV is observed in the high-harmonic-generation spectra of N-2 for several laser intensities and frequencies. This minimum appears to be invariant for different molecular orientations. We reproduce this minimum for a set of laser parameters and orientations in time-dependent density-functional-theory calculations, which also render orientation-dependent maxima at 23-26 eV. Photon energies of these maxima overlap with ionization potentials of excited states observed in photoelectron spectra. Time profile analysis shows that these maxima are caused by resonance-enhanced multiphoton excitation. We propose a four-step mechanism, in which an additional excitation step is added to the well-accepted …

In October-November 2011 we measured trace gas emission factors from seven prescribed fires in South Carolina (SC), US, using two Fourier transform infrared spectrometer (FTIR) systems and whole air sampling (WAS) into canisters followed by gas-chromatographic analysis. A total of 97 trace gas species were quantified from both airborne and ground-based sampling platforms, making this one of the most detailed field studies of fire emissions to date. The measurements include the first emission factors for a suite of monoterpenes produced by heating vegetative fuels during field fires. The first quantitative FTIR observations of limonene in smoke are reported along with …

The Role Of Faculty In The Effectiveness Of Fully Online Programs, Sami Al Salman

CCE Theses and Dissertations

The enormous growth of online learning creates the need to develop a set of standards and guidelines for fully online programs. While many guidelines do exist, web-based programs still fall short in the recognition, adoption, or the implementation of these standards. One consequence is the high attrition rates associated with web-based distance learning programs. This poor outcome has a negative impact on the perceived quality of these programs which in turn limits the resources that are made available to academic institutions for implementation. Faculty plays a significant role in this dilemma. While academic administrators strive to enhance their online offerings …

Code Clone Discovery Based On Concolic Analysis, Daniel Edward Krutz

CCE Theses and Dissertations

Software is often large, complicated and expensive to build and maintain. Redundant

code can make these applications even more costly and difficult to maintain. Duplicated

code is often introduced into these systems for a variety of reasons. Some of which

include developer churn, deficient developer application comprehension and lack of

adherence to proper development practices.

Code redundancy has several adverse effects on a software application including an

increased size of the codebase and inconsistent developer changes due to elevated

program comprehension needs. A code clone is defined as multiple code fragments that

produce similar results when given the same input. …

Toward The Implementation Of Augmented Reality Training, Charles Randall Mayberry

CCE Theses and Dissertations

The United States Air Force (USAF) trains C-130H Loadmaster students at Little Rock Air Force Base (AFB) through a civilian contract. The Aircrew Training System (ATS) contractor utilizes a Fuselage Trainer (FuT) to provide scenarios for the Loadmaster students to practice loading and unloading a simulated aircraft. The problem was the USAF does not have enough training devices and these devices are not at a high enough fidelity to accomplish many of the aircraft functions to meet the training objectives before flying on the actual aircraft. The ATS has moved the pilot's initial training into the Weapon System Trainer (WST). …

Application Of A Layered Hidden Markov Model In The Detection Of Network Attacks, Lawrence Taub

CCE Theses and Dissertations

Network-based attacks against computer systems are a common and increasing problem. Attackers continue to increase the sophistication and complexity of their attacks with the goal of removing sensitive data or disrupting operations. Attack detection technology works very well for the detection of known attacks using a signature-based intrusion detection system. However, attackers can utilize attacks that are undetectable to those signature-based systems whether they are truly new attacks or modified versions of known attacks. Anomaly-based intrusion detection systems approach the problem of attack detection by detecting when traffic differs from a learned baseline. In the case of this research, the …

An Examination Of Internet Filtering And Safety Policy Trends And Issues In South Carolina's K-12 Public Schools, Mary E. Vicks

CCE Theses and Dissertations

School districts have implemented filtering and safety policies in response to legislative and social mandates to protect students from the proliferation of objectionable online content. Subject related literature suggests these policies are more restrictive than legal mandates require and are adversely affecting information access and instruction. There is limited understanding of how filtering and safety policies are affecting teaching and learning because no comprehensive studies have investigated the issues and trends surrounding filtering and safety policy implementation. In order to improve existing safety policies, policymakers need research-based data identifying end user access issues that limit technology integration in the kindergarten-12th …

Spectral Characterization Of The Nigerian Shoreline Using Landsat Imagery, Olumide Fadahunsi, Shachak Pe'eri, Christopher Parrish, Andy Armstrong, Lee Alexander

Center for Coastal and Ocean Mapping

The challenges of shoreline mapping include the high costs of acquiring up-to-date survey data over the coastal area. As a result, in many developing countries, the shoreline has not been consistently mapped. The variety of methods used for this mapping and the large time differences between the surveys (on the order of decades) could result in inaccuracies in shoreline data. This study presents the development of a shoreline characterization procedure for the Nigerian coastline using satellite remote sensing technology. The study goal is to produce a complete, consistent and continuous shoreline map using publicly available data processed in a GIS …

Seabed Classification For Trawlability Determined With A Multibeam Echo Sounder On Snakehead Bank In The Gulf Of Alaska, Thomas C. Weber, Chris Rooper, John L. Butler, Darin Jones, Chris Wilson

Center for Coastal and Ocean Mapping

—Rockfishes (Sebastes spp.) tend to aggregate near rocky, cobble, or generally rugged areas that are difficult to survey with bottom trawls, and evidence indicates that assemblages of rockfish species may differ between areas accessible to trawling and those areas that are not. Consequently, it is important to determine grounds that are trawlable or untrawlable so that the areas where trawl survey results should be applied are accurately identified. To this end, we used multibeam echosounder data to generate metrics that describe the seafloor: backscatter strength at normal and oblique incidence angles, the variation of the angle-dependent backscatter strength within 10° …
