The Octonions And The Exceptional Lie Algebra G2, Ian M. Anderson

Research Vignettes

The octonions O are an 8-dimensional non-commutative, non-associative normed real algebra. The set of all derivations of O form a real Lie algebra. It is remarkable fact, first proved by E. Cartan in 1908, that the the derivation algebra of O is the compact form of the exceptional Lie algebra G2. In this worksheet we shall verify this result of Cartan and also show that the derivation algebra of the split octonions is the split real form of G2.

Naturalness And Biodiversity: Why Natural Conditions Should Be Maintained Within Protected Areas, Gorden Steinhoff

Languages, Philosophy, and Communication Studies Faculty Publications

In this Article, I will argue that naturalness (natural conditions) should be maintained as a mandatory goal in the management of protected areas. It will be important to describe in detail what naturalness as a management goal consists of. Within Beyond Naturalness, Cole, Yung, and other authors misrepresent the naturalness mandated within protected area law and policy. I wish to defend the claim that naturalness, properly understood, is necessary for the preservation of native biodiversity. I will describe an interesting case study in which managers have intervened in wilderness to conserve "what we value" without respect for natural conditions, and …

Mechanisms In Decorin Regulation Of Vascular Endothelial Growth Factor-Induced Human Trophoblast Migration And Acquisition Of Endothelial Phenotype, Neena Lala, Gannareddy V. Girish, Alia Cloutier-Bosworth, Peeyush K. Lala

Paediatrics Publications

Extravillous trophoblast (EVT) cells of the human placenta invade the uterine decidua and utero-placental arteries to establish an efficient exchange of key molecules between maternal and fetal blood. Trophoblast invasion is stringently regulated in situ both positively and negatively by a variety of factors at the fetal-maternal interface to maintain a healthy utero-placental homeostasis. One such factor, decorin, a transforming growth factor (TGF)-beta binding, leucine-rich proteoglycan produced by the decidua, negatively regulates EVT proliferation, migration, and invasiveness independent of TGFbeta.We reported that these decorin actions were mediated by its binding to multiple tyrosine kinase receptors, including vascular endothelial growth factor …

Manifestations Of Ideational Landscapes: Heaven, Hell And Film, Hillary Christopher

Spectrum

There is a place where you walk upon the clouds. Before entering, you must go through a golden gate of sorts. Once passed, all of your loved ones smile and greet you. There might be a flock of doves flying someplace in the distance. Somewhere else is another place constructed not of clouds, but of jagged rocks. This place is dark and full of fire. You feel alone, full of dread and fear.

These two places should be familiar despite a simple description. Hopefully you identified them as Heaven and Hell, respectively. They are classified as one of the three …

Renew, Reflect, Rejoice: Immersion To The Rescue, Pamela N. Martin, Erin Davis

Library Faculty & Staff Publications

Feel burned out from teaching the same monotonous one-shot library instruction sessions? Worry that all of your colleagues are always creating dynamic lesson plans, while you’re stuck using the same one? Forget the last time you even thought about why you’re teaching? As library instructors, we’ve all felt this way. As the pressures and demands on teaching librarians grow, we believe the need for Immersion is more essential than ever. Many, if not most, librarians receive little or no formal training focused on instruction, but Immersion can help address this critical gap and pave the way to more thoughtful library …

Camper Outcomes Increase Regardless Of Session Length: Beyond Anecdotal Evidence Of Increased Competence, Independence And Friendship Skills, Mark F. Roark

Kinesiology and Health Science Faculty Publications

Session length may not be as vital to the accomplishment of developmental outcomes as directors are anecdotally sharing. Interestingly, no empirical support exists for the conventional wisdom that longer sessions have better outcomes than shorter sessions for campers. Dimock and Hendry (1929) found that campers’ level of development in general did not significantly vary whether they were at camp one or two months. They cautioned that this finding might not appropriately represent the actual effect of camp due to limitations in the measurement tool. Comparably, ACA’s Directions (2005) reported that session length was not a reliable predictor of camper developmental …

Fortification Of Cheese With Vitamin D3 Using Dairy Protein Emulsions As Delivery Systems, M. Tippetts, Silvana Martini, C. Brothersen, D. J. Mcmahon

Nutrition, Dietetics, and Food Sciences Faculty Publications

Vitamin D is an essential vitamin that is synthesized when the body is exposed to sunlight or after the consumption of fortified foods and supplements. The purpose of this research was to increase the retention of vitamin D3 in Cheddar cheese by incorporating it as part of an oil-in-water emulsion using a milk protein emulsifier to obtain a fortification level of 280 IU/serving. Four oil-in-water vitamin D emulsions were made using sodium caseinate, calcium caseinate, nonfat dry milk (NDM), or whey protein. These emulsions were used to fortify milk, and the retention of vitamin D3 in cheese curd in a …

Genetics For The Ophthalmologist., Karthikeyan A Sadagopan, Jenina Capasso, Alex V Levin

Wills Eye Hospital Papers

The eye has played a major role in human genomics including gene therapy. It is the fourth most common organ system after integument (skin, hair and nails), nervous system, and musculoskeletal system to be involved in genetic disorders. The eye is involved in single gene disorders and those caused by multifactorial etiology. Retinoblastoma was the first human cancer gene to be cloned. Leber hereditary optic neuropathy was the first mitochondrial disorder described. X-Linked red-green color deficiency was the first X-linked disorder described. The eye, unlike any other body organ, allows directly visualization of genetic phenomena such as skewed X-inactivation in …

Evaluation Of Persistence And Relative Toxicity Of Some Pest Control Products To Adults Of Two Native Trichogrammatid Species In Kenya, G. Momanyi, R. Maranga, S. Sithanantham, S. Agong, C. M. Matoka, S. A. Hassan

All Peer-Reviewed Publications

The utilization of native trichogrammatids for biocontrol of Helicoverpa armigera (Hbn.) and their potential integration with pesticide use are currently receiving attention. In this study the interaction of adults of Trichogramma sp. nr. mwanzai and Trichogrammatoidea sp. nr. lutea with commonly used pesticide products was investigated. The toxicity of eight pest control products commonly used in vegetable crops in Kenya, were evaluated by exposing the adults of the two species to detached potted tomato leaves at different intervals after spraying. Two biologically derived products, Achook ® (neem-based) and Dipel ® (Bt ssp. kurstaki)-were found to be harmless and had no …

Mediation Of A Plant-Spider Association By Specific Volatile Compounds, Ximena J. Nelson, Andrew J. Pratt, Xavier Cheseto, Baldwyn Torto, Robert R. Jackson

All Peer-Reviewed Publications

Evarcha culicivora, an East African jumping spider (Salticidae), is the only spider for which there is evidence of innate olfactory affinity for particular plant species. Evarcha culicivora also actively chooses as preferred prey the females of Anopheles mosquitoes, and both sexes of Anopheles are known to visit plants for nectar meals. Here, we identified compounds present in the headspace of one of these species in Kenya, Lantana camara, and then used 11 of these compounds in olfactometer experiments. Our findings show that three terpenes [(E)-β-caryophyllene, α-humulene and 1,8 cineole] can be discriminated by, and are salient to, E. culicivora. The …

A Comparison Of Traditional And Bayesian Statistical Models In Fluvial Sediment Transport, Mark L. Schmelter, David King Stevens

Civil and Environmental Engineering Faculty Publications

The characterization of sediment transport is an important problem that has been actively studied for some time. Numerous approaches have been demonstrated in the literature, including mechanistic models, probabilistic arguments, machine learning algorithms, and empirical formulations. Most implementations of sediment transport relations are deterministic in nature and require the specification of model parameters. These parameters are traditionally assumed fixed (i.e., a single value), and subsequent predictions are not necessarily representative because of uncertainty because they are fixed (i.e., a line). In this paper, a Bayesian statistical sediment transport model is presented, and its ability to infer critical shear values from …

Martharaptor Greenriverensis, A New Theropod Dinosaur From The Lower Cretaceous Of Utah, Phil Senter, James I. Kirkland, Donald D. Deblieux

College of Health, Science, and Technology

Background: The Yellow Cat Member of the Cedar Mountain Formation (Early Cretaceous, Barremian?) of Utah has yielded a rich dinosaur fauna, including the basal therizinosauroid theropod Falcarius utahensis at its base. Recent excavation uncovered a new possible therizinosauroid taxon from a higher stratigraphic level in the Cedar Mountain Formation than F. utahensis. Methodology/Principal Findings: Here we describe a fragmentary skeleton of the new theropod and perform a phylogenetic analysis to determine its phylogenetic position. The skeleton includes fragments of vertebrae, a scapula, forelimb and hindlimb bones, and an ischium. It also includes several well-preserved manual unguals. Manual and pedal morphology …

Higher Order Symmetries Of The Kdv Equation, Ian M. Anderson

Research Vignettes

In this worksheet we symbolically construct the formal inverse of the total derivative operator and use it to construct the recursion operator for the higher-order symmetries of the KdV equation. Using this recursion operator we generate the first 5 generalized symmetries of the KdV equation and verify that they all commute.

Molecule For Electronics: A Myriad Of Opportunities Comes With Daunting Challenges, Ranjit Pati

Department of Physics Publications

Since the invention of Integrated Circuit (IC) in 1958, we have seen an unprecedented growth in Si-based electronics industry; ICs are currently used in almost all electronic gadgets. However, it is now very much clear that this era of growth we have been witnessing for the last five decades will soon hit the brick wall, once the transistor size reaches the physical limit of miniaturization.

“It Depends On Where You Go!” The Transnational Racial Consciousness Of Dominican Immigrants, Lucinda Bratini

Faculty and Staff Publications & Presentations

This study aimed to explore transnational racial consciousness among immigrants from the Dominican Republic. Racial consciousness is the process whereby the people develop awareness and understanding of social oppression (Freire, 1971; Quintana and Segura-Herrera, 2003, p. 274). Fifteen self-identified Dominican immigrants participated in semi-structured interviews, focused on their understandings of skin-color, racialization, racism, and group membership. A grounded theory design framed from a constructivist and critical social justice approach guided the analysis of the data. The theoretical framework that emerged from the analysis of the data suggests a core narrative of “negotiating contradicting cultural scripts” about race and racialization and …

Nitric Oxide Releasing Polymers For Vascular Graft Applications, Ifeanyi U. Onyejekwe

Biomedical and Chemical Engineering - Dissertations

Nitric oxide [NO] is an endogenous gas involved in a multitude of physiological functions, ranging from vasodilatation, inflammatory response to inhibition of platelet aggregation. Significant interest exists for therapeutic application of exogenous NO, particularly for the improvement of foreign-body responses of biomaterials. One challenge amongst several others that must be taken into consideration is NO's short half-life, ranging from 2-3 s, in physiological systems. Researchers have worked on synthesizing materials, formally referred to as NO donors/NONOates capable of preserving NO and spontaneous gas release upon contact with blood under physiological conditions. Two groups of these commercially available NO donors known …

Past Matters, Marilyn Gottlieb

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Past Matters is the story of the 20th century following WW II through the eyes of a child who becomes an adult while surviving political, economic and professional setbacks beyond his control. Frank Levy was born a Jew in Berlin in 1933 when Hitler came into power. His parents fled Germany in 1936 before travel was forbidden for Jews. He was raised in the British Mandate of Palestina and moved to America in 1946. The reader follows Levy as he adjusts to a third culture, third language and third name. He becomes a mechanical engineer in the textile machinery industry …

Auto-Fluorescence Lifetime And Light Reflectance Spectroscopy For Breast Cancer Diagnosis: Potential Tools For Intraoperative Margin Detection, Vikrant Sharma, Shivaranjani Shivalingaiah, Yan Peng, David Euhus, Zygmunt Gryczynski, Hanli Liu

Bioengineering Faculty Publications - Archive

This study investigates the use of two spectroscopic techniques, auto-fluorescence lifetime measurement (AFLM) and light reflectance spectroscopy (LRS), for detecting invasive ductal carcinoma (IDC) in human ex vivo breast specimens. AFLM used excitation at 447 nm with multiple emission wavelengths (532, 562, 632, and 644 nm), at which autofluorescence lifetimes and their weight factors were analyzed using a double exponent model. LRS measured reflectance spectra in the range of 500-840 nm and analyzed the spectral slopes empirically at several distinct spectral regions. Our preliminary results based on 93 measured locations (i.e., 34 IDC, 31 benign fibrous, 28 adipose) from 6 …

Planning For Crime: Crime Prevention Through Environmental Design In Bishop Arts District Neighborhood, Oak Cliff, Dallas., Sharmila Gurung, Ardeshir Anjomani

Planning Masters Professional Reports - Archive

There is a lack of emphasis in the planning world, both academically and in the field, on preventing crime. Defensible Space and Crime Prevention through Environmental Design (CPTED) has been the two main approaches taken by planners and criminal justice officials that is design-based and that has brought some level of collaboration between the two professions. This study analyzes the built environment of select crime hotspots in the Bishop Arts District Neighborhood from a design-based crime prevention perspective in order to draw correlations between high crime areas and elements of design-based theories. Using GIS software, crime map is plotted to …

Designing A Simple Indirect Vector Controlled Drive System In Simulink, Ryan M. Hanlon

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, the need for alternative fueled vehicles has been highlighted by government and industry leaders. The emphasis has focused on hybrid/electric drive systems. In order to compete with current technology, these drives must be capable of operating under various load conditions as well as operating over a large speed range. Such performance requirements require motor control systems that must be capable of overcoming changes within the drive system: primarily motor parameter changes at high speed operation. While multiple control algorithms exist for electric drives, some offer more robust control than others. These algorithms range in cost and complexity.;The …

Mass Spectral Determination Of Phenylacetonitrile (Pan) Levels In Body Tissues Of Adult Desert Locust, Schistocerca Gregaria, Peris W. Amwayi, Daniel K. Masiga, Prem Govender, Peter E.A. Teal, Baldwyn Torto

All Peer-Reviewed Publications

Wings and legs of the gregarious desert locust, Schistocerca gregaria have been shown to be release sites of phenylacetonitrile (PAN), the major adult male-produced pheromone. However, there is limited information on the distribution of PAN within the locust. Here we show, using gas chromatography-mass spectrometry (GC-MS), that PAN occurs in nearly all body parts of both adult males and females of the locust in varying amounts. PAN was 20-fold more concentrated in males than in females. In females, PAN was concentrated more in the tarsal segments. The greatest amounts of PAN were in 2- and 3-week old female and male …

Palaeoenvironmental Shifts Drove The Adaptive Radiation Of A Noctuid Stemborer Tribe (Lepidoptera, Noctuidae, Apameini) In The Miocene, Emmanuel F.A. Toussaint, Fabien L. Condamine, Gael J. Kergoat, Claire Capdevielle-Dulac, Jérôme Barbut, Jean François Silvain, Bruno P. Le Ru

All Peer-Reviewed Publications

Between the late Oligocene and the early Miocene, climatic changes have shattered the faunal and floral communities and drove the apparition of new ecological niches. Grassland biomes began to supplant forestlands, thus favouring a large-scale ecosystem turnover. The independent adaptive radiations of several mammal lineages through the evolution of key innovations are classic examples of these changes. However, little is known concerning the evolutionary history of other herbivorous groups in relation with this modified environment. It is especially the case in phytophagous insect communities, which have been rarely studied in this context despite their ecological importance. Here, we investigate the …
