Representation And Learning For Sign Language Recognition, Sunita Nayak

USF Tampa Graduate Theses and Dissertations

While recognizing some kinds of human motion patterns requires detailed feature representation and tracking, many of them can be recognized using global features. The global configuration or structure of an object in a frame can be expressed as a probability density function constructed using relational attributes between low-level features, e.g. edge pixels that are extracted from the regions of interest. The probability density changes with motion, tracing a trajectory in the latent space of distributions, which we call the configuration space. These trajectories can then be used for recognition using standard techniques such as dynamic time warping. Can these frame-wise …

Assessment Of Paper Birch Trees Tapped For Sap Harvesting Near Fairbanks, Alaska, Lori Trummer, Tom Malone

Publications

With increased growth in the birch sap extraction industry, the need for assessments of tree health and sustainability of birch tapping practices also grows. Site visits and evaluation of tapping practices were conducted at two commercial harvest locations in the Fairbanks area, Eva Creek in Ester and Cache Creek near Murphy Dome in 2007. In this evaluation we report on walk through observations and a pilot dissection study of tapped trees at each location. Numerous improper tapping practices are reported as well as breach of the Alaska Birch Syrupmakers’ Association (ABSA) “Best Practices Guidelines for Tree Tapping”. There will be …

Assessing The Role Of Multi-Protein Complexes In Determining Phenotype, Nolwenn Le Meur, Robert Gentleman

Bioconductor Project Working Papers

Understanding regulatory mechanisms in complex biological systems is an important challenge, in particular to understand disease mechanisms, and to discover new therapies and drugs. In this paper, we consider the important question of cellular regulation of phenotype. Using single gene deletion data, we address the problem of linking a phenotype to underlying functional roles in the organism and provide a sound computational and statistical paradigm that can be extended to address more complex experimental settings such as multiple deletions. We apply the proposed approaches to publicly available data sets to demonstrate strong evidence for the involvement of multi-protein complexes in …

Strictosidine Synthase: Mechanism Of A Pictet-Spengler Catalyzing Enzyme, Justin J. Maresh, Lesley Ann Giddings, Anne Friedrich, Elke A. Loris, Santosh Panjikar, Bernhardt L. Trout, Joachim Stöckigt, Baron Peters, Sarah E. O'Connor

Chemistry: Faculty Publications

The Pictet-Spengler reaction, which yields either a β-carboline or a tetrahydroquinoline product from an aromatic amine and an aldehyde, is widely utilized in plant alkaloid biosynthesis. Here we deconvolute the role that the biosynthetic enzyme strictosidine synthase plays in catalyzing the stereoselective synthesis of a β-carboline product. Notably, the rate-controlling step of the enzyme mechanism, as identified by the appearance of a primary kinetic isotope effect (KIE), is the rearomatization of a positively charged intermediate. The KIE of a nonenzymatic Pictet-Spengler reaction indicates that rearomatization is also rate-controlling in solution, suggesting that the enzyme does not significantly change the mechanism …

Microbes And The Days Of Creation, Alan L. Gillen

Faculty Publications and Presentations

The world of germs and microbes has received much attention in recent years. But where do microbes fit into the creation account? Were they created along with the rest of the plants and animals in the first week of creation, or were they created later, after the Fall? These are some questions that creation microbiologists have been asking in recent years. Ongoing research, based on the creation paradigm, appears to provide some answers to these puzzling questions. The answers to these questions are not explicit in Scripture, so the answers cannot be dogmatic. However, a reasonable extrapolation from biological data …

Entrepreneurship As Emergence, Benyamin B. Lichtenstein

College of Management Working Papers and Reports

Emergence is at the core of entrepreneurship research, which has explored the coming-intobeing of opportunities, new organizations, re-organizations, and new industries, agglomerations, and so on. Emergence is also at the theoretical core of complexity science, which is essentially dedicated to exploring how and why emergence happens in dynamic systems (like entrepreneurship). This exploration begins by defining Opportunity In-tension as a dynamic interplay of personal agency and perceived opportunity, which is a catalyst for entrepreneurial behavior. Then I propose two insights about emergence, based on recent research in complexity science. First, a process theory for emergence is presented, which integrates Gartner’s …

Mechanical Behavior And Failure Analysis Of Prosthetic Retaining Screws After Long‐Term Use In Vivo. Part 4: Failure Analysis Of 10 Fractured Retaining Screws Retrieved From Three Patients, Youssef S. Al Jabbari, Raymond Fournelle, Gerald J. Ziebert, Jeffrey M. Toth, Anthony Iacopino

Biomedical Engineering Faculty Research and Publications

Purpose: The aim of this study was to perform a failure analysis on fractured prosthetic retaining screws after long‐term use in vivo. Additionally, the study addresses the commonly asked question regarding whether complex repeated functional occlusal forces initiate fatigue‐type cracks in prosthetic retaining screws.

Materials and Methods: Ten fractured prosthetic retaining screws retrieved from three patients treated with fixed detachable hybrid prostheses were subjected to a failure analysis. In patients 1 and 2, the middle three retaining screws of the prostheses were found fractured at retrieval time after they had been in service for 20 and 19 months, respectively. In …

Interspecific Hybridization Yields Strategy For South Pacific Filariasis Vector Elimination, Corey L. Brelsfoard, Yves Séchan, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: Lymphatic filariasis (LF) is a leading cause of disability in South Pacific regions, where >96% of the 1.7 million population are at risk of LF infection. As part of current global campaign, mass drug administration (MDA) has effectively reduced lymphatic filiariasis prevalence, but mosquito vector biology can complicate the MDA strategy. In some regions, there is evidence that the goal of LF elimination cannot be attained via MDA alone. Obligate vector mosquitoes provide additional targets for breaking the LF transmission cycle, but existing methods are ineffective for controlling the primary vector throughout much of the South Pacific, Aedes polynesiensis. …

A Method To Determine 18 O Kinetic Isotope Effects In The Hydrolysis Of Nucleotide Triphosphates, Xinlin Du, Kurt Ferguson, Robert Gregory, Stephen R. Sprang

Biological Sciences Faculty Publications

A method to determine 18 O kinetic isotope effects (KIEs) in the hydrolysis of GTP that is generally applicable to reactions involving other nucleotide triphosphates is described. Internal competition, where the substrate of the reaction is a mixture of 18 O-labeled and unlabeled nucleotides, is employed, and the change in relative abundance of the two species in the course of the reaction is used to calculate KIE. The nucleotide labeled with 18 O at sites of mechanistic interest also contains 13C at all carbon positions, whereas the 16 O-labeled nucleotide is depleted of 13C. The relative abundance of the labeled …

Sargassum Fusiforme Fraction Is A Potent And Specific Inhibitor Of Hiv-1 Fusion And Reverse Transcriptase, Elena E. Paskaleva, Xudong Lin, Karen Duus, James J. Mcsharry, Jean-Claude L. Veille, Carol S. Thornber, Yanze Liu, David Yu-Wei Lee, Mario Canki

Biological Sciences Faculty Publications

Sargassum fusiforme (Harvey) Setchell has been shown to be a highly effective inhibitor of HIV-1 infection. To identify its mechanism of action, we performed bioactivity-guided fractionation on Sargassum fusiforme mixture. Here, we report isolation of a bioactive fraction SP4-2 (S. fusiforme), which at 8 μg/ml inhibited HIV-1 infection by 86.9%, with IC₅₀ value of 3.7 μg. That represents 230-fold enhancement of antiretroviral potency as compared to the whole extract. Inhibition was mediated against both CXCR4 (X4) and CCR5 (R5) tropic HIV-1. Specifically, 10 μg/ml SP4-2 blocked HIV-1 fusion and entry by 53%. This effect was reversed by …

A Tick From A Prehistoric Arizona Coprolite (Galley Proofs), Keith L. Johnson, Karl J. Reinhard, Luciana Sianto, Adauto Araújo, Scott Lyell Gardner, John J. Janovy Jr.

School of Natural Resources: Faculty Publications

Ticks have never been reported in archaeological analyses. Here, we present the discovery of a tick from a coprolite excavated from Antelope Cave in extreme northwest Arizona. Dietary analysis indicates that the coprolite has a human origin. This archaeological occupation is associated with the Ancestral Pueblo culture (Anasazi). This discovery supports previous hypotheses that ticks were a potential source of disease and that ectoparasites were eaten by ancient people.

Determination Of Pharmacologically Active Compounds In Root Extracts Of Cassia Alata L. By Use Of High Performance Liquid Chromatography, Vivian E. Fernand, David T. Dinh, Samuel J. Washington, Sayo O. Fakayode, Jack N. Losso, Rick O. Van Ravenswaay, Isiah M. Warner

Faculty Publications

A simple high performance liquid chromatography (HPLC) method was developed and validated for the determination of six phenolic compounds, five anthraquinones (rhein, aloe-emodin, emodin, chrysophanol and physcion) and a flavonoid (kaempferol), in root extracts from Cassia alata L. Solid-phase extraction, using C18 cartridges, was used to remove interfering substances from the root extracts. The extracts were analyzed on a C18 column using an isocratic mobile phase which consisted of acetonitrile, methanol, and 10 mM aqueous ammonium acetate (25:55:20, v/v). Identification of the analytes was performed by use of standards and on-line mass spectrometric detection using atmospheric pressure chemical ionization. The …
