Recent Advances In Content-Based Video Analysis, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang

Research Collection School Of Computing and Information Systems

In this paper, we present major issues in video parsing, abstraction, retrieval and semantic analysis. We discuss the success, the difficulties and the expectations in these areas. In addition, we identify important opened problems that can lead to more sophisticated ways of video content analysis. For video parsing, we discuss topics in video partitioning, motion characterization and object segmentation. The success in video parsing, in general, will have a great impact on video representation and retrieval. We present three levels of abstracting video content by scene, keyframe and key object representations. These representation schemes in overall serve as a good …

The Effect Of Multiple Pulses On Bacteria, Ramy El-Sayed Aly

Electrical & Computer Engineering Theses & Dissertations

Pulsed electric fields are widely used for bacterial decontamination of water and liquid food [I]. Depending on pulse amplitude and duration, a certain percentage of the bacteria suffer irreversible damage and, consequently, cell death. We have explored the effect of microsecond pulses of 13 kV/cm and 15 kV/cm electric field amplitude on the viability of Escherlchia coli. The pulse duration was varied from 4 μs to 32 μs, and the pulse number of 4 μs pulses from one to eight, Finally, the effect of separation between pulses was studied. The pulses were generated by means of a generator where …

Motion Perception Of Angularly Expanding Stimuli Within A Presence Versus Absence Framework, Nathan R. Bailey

Psychology Theses & Dissertations

Research has shown that searching for the presence of a feature among featureless distractors is easier than searching for the absence of a feature among distractor objects containing the feature. The present study examined motion perception within this context while manipulating motion type and target density. Further, the element of angular expansion was also included as part of the moving stimuli. Using a standard computer interface, participants were asked to respond as quickly as they could to a variety of moving stimuli. Results showed that it took more time to detect stationary targets among moving distractors than to find moving …

Sulphur By-Product: A Potential Indicator Of Early Dental Plaque-Induced Gingival Disease Activity: A Pilot Study, Hui Zhou

Dental Hygiene Theses & Dissertations

The purpose of this study was to determine the relationship between volatile sulfide compounds and gingival health status, and to identify if volatile sulfide compounds can detect early dental plaque-induced gingival disease, using an experimental gingivitis model. The sample consisted of 12 subjects between 19 and 28 years, with a healthy gingival status. A split-mouth design utilizing only the mandibular arch was used. A baseline full-mouth periodontal probing status was measured. After baseline data collection and for two weeks, subjects refrained from brushing and flossing one randomly selected half of the mandibular arch. At baseline and six subsequent appointments, gingival …

Positive Regulation Of Pka On Human Gonadotropin-Releasing Hormone (Hgnrh) Gene Expression In Human Placental Jeg-3 Cells, Zhaoyang Wen

Chemistry & Biochemistry Theses & Dissertations

Using the human placental choriocarcinoma JEG-3 cell line as an in vitro human placental model, we studied the mechanisms of the PKA positive regulation of the hGnRH gene expression in the human placenta. Studies in JEG3 cells showed that through the PKA catalytic subunit a, human GnRH upstream promoter activity was stimulated by PKA signaling pathway in a cAMP dependent mechanism. The sequence between —202 (Afl II) and —554 (BamH I) base pair in the human GnRH upstream promoter region appeared to be responsible for the PKA positive regulation of the gene expression. Furthermore, Western blot analysis demonstrated the involvement …

Beyond The Counter-Majoritarian Difficulty: Judicial Decision-Making In A Polynomic World, Daniel J.H. Greenwood

Hofstra Law Faculty Scholarship

This Article examines the role of judicial deference in a modern democracy. The Author disputes the view that judges defer to legislatures because legislatures are more majoritarian than judges. In refuting this view, the Author first outlines a theory of democracy as partnership. He then describes and discusses the main decisionmaking processes of a modern democracy, including aggregation processes such as majoritarian politics, economic markets, and civil society, as well as normative systems such as judiciaries, bureaucracies, and professionals, emphasizing the failure of each, taken alone, to satisfy democratic ideals. The Author contends that in order to understand and appreciate …

Estrogen Regulation Of The Pregnant Baboon Placental 11Β-Hydroxysteroid Dehydrogenase (11Β-Hsd)-Catalyzed Metabolism Of Cortisol And Cortisone And Its Effect On The Development Of The Fetal Hypothalamic-Pituitary-Adrenal Axis, William Adair Davies

Theses and Dissertations in Biomedical Sciences

Pepe and Albrecht previously demonstrated that the estrogen-regulated change in transuteroplacental metabolism of cortisol (F) and cortisone (E) from preferential reduction (E to F) at midgestation to oxidation (F to E) near term results in a decline of bioactive cortisol crossing the placenta and reaching the fetus culminating in activation of the hypothalamic-pituitary adrenal axis of the baboon and the ontogenesis of rate-limiting steroidogenic enzymes culminating in de novo F secretion. Protein kinase A (PK-A) activity in the baboon fetal adrenal gland cytosolic fraction was increased 2-fold both at term [day 165 of gestation (term = 184 days)] and following …

Interactions Among Murine Cytomegalovirus Us22 Family Gene Products That Influence Viral Pathogenesis, Zaruhi Karabekian

Theses and Dissertations in Biomedical Sciences

Cytomegalovirus (CMV) is a complex, ubiquitous herpesvirus that is characterized by acute, chronic, and latent infections. Monocytes-macrophages are the key target cell type involved in pathogenesis, which is most effectively studied using the murine model of CMV infection. Previously three murine CMV (MCMV) genes (M139, M140, and M141) were identified to regulate viral expression in cultured macrophages and in mice. These genes are members of the US22 gene family with respect to HCMV homology. There is no function assigned to the proteins encoded by these genes. However, deletion of M139, M140, and M141 significantly curtails growth of MCMV in macrophages …

Regulation Of The Hcmv Ul98 Promoter By Cooperation Of The Cyclic Amp Response Element And Gamma Interferon Response Element, Tabmitha Patricia Young Jervey

Theses and Dissertations in Biomedical Sciences

The HCMV UL98 early alkaline exonuclease gene promoter was examined to determine the DNA sequences as well as viral and/or cellular proteins functional in the regulation of this early gene. To assess promoter activation, UL98 promoter sequences were first cloned upstream of the chloramphenicol acetyltransferase (CAT) reporter gene and cotransfected with expression plasmids which express the HCMV major immediate early (IE) proteins 1E72 and 1E86. To more specifically determine the importance of individual cis-acting elements in UL98 promoter activation, the promoter region underwent mutagenesis to delete or alter sequences. The variant promoters were again cloned into a reporter-CAT construct and …

Strategy Implementation Effectiveness In A Nonprofit Environment: The Case Of Museum Stores, Sandra A. Mottner

Theses and Dissertations in Business Administration

The character of museums in America has changed significantly in this century as museums change how they market themselves to their constituents. One of these changes has been the growth and development of museum stores. First designed to supplement museum income museum stores are now a major source of museum funding (American Association of Museums 1999) and a source of educational enhancement of the museum's educational mission (Theobald 2000). However, despite the growth of the museum store, virtually no academic research has been undertaken.

This research seeks to help fill this void in the literature of not only museum store …

An Enzymatic Method For The Detection Of Human Serum Albumin, M U. Javed, S N. Waqar

Department of Biological & Biomedical Sciences

Albumin is the most abundant protein in human serum. A dye-binding method is commonly used in clinical laboratories for its estimation using different types of dyes. However, all these dye methods were interfered by a variety of compounds. Here we present a method for the detection of albumin in human serum and other biological fluids. The principle is based on the fact that lactate dehydrogenase isoenzyme-5 (LDH-5) binds specifically to Dextran-Blue (DB). Albumin inhibits the binding of LDH-5 with DB. Absence of LDH activity in DB fraction after gel filtration indicates the presence of albumin in sample and vice versa.

Mammy: From Pancakes To Grenades, Nichol Michelina Pagano

Theses & Honors Papers

From an image draped in calico and flipping pancakes to a figure wearing pearls and throwing hand grenades, Mammy exists as part of America's cultural heritage since the beginning of the nineteenth century. The Mammy character evolved in American iconography from the subservient kitchen Aunt Jemima to a modem aggressive woman ready for military combat. Early depictions of Mammy show her as being very humble, plain in dress and appearance, and subservient to her white masters . In From Mammy to Miss America and Beyond, Sue Jewell states, "[Mammy] is portrayed as an obese African-American woman, of dark complexion, with …
