An Fpga Implementation Of A High Performance Aer Packet Network, Sirish Kumar Munipalli

Dissertations and Theses

This thesis presents a design to route the spikes in a cognitive computing project called Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE). SyNAPSE is a DARPA-funded program to develop electronic neuromorphic ma- chine technology that scales to biological levels. The basic computational block in the SyNAPSE system is the asynchronous spike processor (ASP) chip. This analog core contains the neurons and synapses in a neural fabric and performs the neural and synaptic computations.An ASP takes asynchronous pulses (spikes) as inputs and after some small delay produces asyn- chronous pulses as outputs.The ASP chips are organized in a nxn (where …

Assessing The Performance Of Digital Micromirror Devices For Use In Space-Based Multi-Object Spectrometers, Kenneth Fourspring

Theses

A current need in space-based instrumentation is a reconfigurable slit mask. Several techniques for slit masks have been employed for ground-based astronomical spectrographs. These ground-based instruments have used large discrete components, which are impractical for remote operation in space-based deployment. The Texas Instruments' Digital Micromirror Device (DMD) was originally conceived purely for display purposes, but is a viable candidate to be use as a slit mask in a space-based multi-object spectrograph (MOS). The Integrated Circuit (IC) manufacturing industry has enabled the robust integration of both silicon transistors and Micro-Electrical Mechanical Systems (MEMS) optical components into a very reliable monolithic chip …

Sugar Promotes Vegetative Phase Change In Arabidopsis Thaliana By Repressing The Expression Of Mir156a And Mir156c, Li Yang, Mingli Xu, Yeonjong Koo, Jia He, R. Scott Poethig

Faculty Publications

Nutrients shape the growth, maturation, and aging of plants and animals. In plants, the juvenile to adult transition (vegetative phase change) is initiated by a decrease in miR156. In Arabidopsis, we found that exogenous sugar decreased the abundance of miR156, whereas reduced photosynthesis increased the level of this miRNA. This effect was correlated with a change in the timing of vegetative phase change, and was primarily attributable to a change in the expression of two genes, MIR156A and MIR156C, which were found to play dominant roles in this transition. The glucose-induced repression of miR156 was dependent on the …

Towards Re-Thinking Ecology: Investigating The Influence Of Behavioral Economics On Ecological Thought, Ned Weidner

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

The current mainstream ecological discourse among environmental activists seems to be focused on changing the current paradigm of ecological thinking towards one focused primarily on sustainability through a deeper connection with the Earth. Often these activists argue this deeper connection with the Earth is best achieved through a paradigmatic change in thinking. It is the argument of this paper that those who champion a paradigmatic shift in thinking towards sustainability need to re-think their plan of action for creating a sustainable relationship with the Earth’s environment because changing society’s way of viewing ecological matters as a way to create a …

Satanic Indifference And Ultimate Reality, Brian J. Reis

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

Satan has captured the imagination of writers in the English language for centuries. This figure and the notion of evil have gone through many changes in English literature of the 19th and 20th centuries. Something changed Satan during this time, and made him into an arbiter of truth rather than a figure of rebellion. In The Mysterious Stranger, Mark Twain used him as the grand narrator of the universe who explains the truth of all existence, that life is an illusion. The American horror author H.P. Lovecraft carried this one step further, using Rudolf Otto's mysterium horrendum to divest Satan …

Chicana Aesthetics: A View Of Unconcealed Alterities And Affirmations Of Chicana Identity Through Laura Aguilar’S Photographic Images, Daniel Perez

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

In this paper I will argue that Chicana feminist artist Laura Aguilar, Alma Lopez, Laura Molina, and Yreina D. Cervantez established a continuing counter-narrative of cultural hegemony and Western essentialized hegemonic identification. Through artistic expression they have developed an oppositional discourse that challenges racial stereotypes, discrimination, socio-economic inequalities, political representation, sexuality, femininity, and hegemonic discourse. I will present a complex critique of both art and culture through an inquiry of the production and evaluation of the Chicana feminist artist, their role as the artist, and their contributions to unfixing the traditional and marginalized feminine. I argue that third wave Chicana …

Oxymormon: Feminism Ain't Got No Place On The Pulpit… Or Does It?, Jennifer Johnson-Bell

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

Just as Moraga examines the effects this myth has had on her identity, I will, as a Mormon (although I dis-identify with that label except in the context of my upbringing) and a feminist, explore certain myths perpetuated within the Mormon culture and what effects they have had on my identity as well as my relationship with other Mormon women. Three myths I would like to explore revolve around the concepts of plural marriage (polygamy), priesthood, and the notion of Heavenly Mother. [excerpt]

Quiverfull: Conservative Christian Women And Empowerment In The Home, Juliana Denson

LUX: A Journal of Transdisciplinary Writing and Research from Claremont Graduate University

What is commonly referred to as “The Quiverfull Movement” is defined by its particular brand of “neo-fundamentalist” Christianity that advocates leaving family planning entirely up to God by refusing to use contraception, medical treatments, or, oftentimes, even natural family planning to prevent or control pregnancy and also tends to promote female submission to male headship. Although it has attracted increasing attention from the media and the ire of feminists, it has yet to receive scholarly attention. In this essay, I attempt to present a fair, nonjudgmental treatment of Quiverfull by seriously considering the experiences and words of Quiverfull-minded Christians, particularly …

Etudes On Iurids, Ii. Revision Of Genus Calchas Birula, 1899, With The Description Of Two New Species (Scorpiones: Iuridae), Victor Fet, Michael E. Soleglad, František Kovařík

Euscorpius

The relict, phylogenetically important scorpion genus Calchas Birula, 1899 (Iuridae) remained monotypic since its description. Its sole species, Calchas nordmanni Birula, 1899, was known only from northeastern Turkey until Kinzelbach (1980) published first records from southern and southeastern Turkey. A few more localities have been reported from Turkey; the species was also found on two Greek islands, Samos and Megisti. We analyzed significant material (63 specimens, including a previously unpublished large series from Naturhistorisches Museum Wien), and concluded that three distinct, disjunct species exist rather than one widespread species as previously thought. Two new species are described: Calchas birulai sp. …

Ecological Niche Modeling Of Two Scorpion Species Mesobuthus Eupeus (C. L. Koch, 1839) And M. Phillipsii (Pocock, 1889) From The Iranian Plateau And Zagros Region (Arachnida: Scorpiones), Omid Mirshamsi

Euscorpius

Ecological niche modeling has allowed several advances in the process of species delimitation. In the present study, I used this method to evaluate the climatic divergence between two scorpion species, Mesobuthus eupeus and M. phillipsii. The ecological niche models (ENMs) were created based on presence-only data with the maximum entropy method. The created models, results of spatial analysis (PCA and Hotelling discriminant), and an identity test suggested that the divergence between these two species is associated with significant divergence in their ecological niches. The results of this study provide additional support for the taxonomic validity the studied species.

A New Species Of Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) From Dominican Amber, Wilson R. Lourenço

Euscorpius

Tityus azari sp. n., a new species of fossil scorpion belonging to the genus Tityus C. L. Koch, 1836 is described based on a specimen in amber from the Dominican Republic. Although the new species can be associated with the extant fauna of the Neotropical region, it presents some particular morphological features such as the presence of sharp denticles on the edge of pedipalp fingers. Due to the incompleteness of the specimen it cannot be assigned to any precise extant subgenera. Once again, this discovery attests to a considerable degree of diversity in the Dominican amber-producing forests.

Feeble To Effeminacy: Race And Gender In The British Imperial Consciousness 1837-1901, Brett Linsley

Grand Valley Journal of History

Scholars of British imperialism have given ample attention to European concepts of race and gender during the Victorian era. Much of the literature has vaguely suggested a symbiotic relationship between the concepts, but failed to assert any definitive theories. The following attempts to fill this gap by putting forward a critical interpretation of the roles that race and gender played in the imperial consciousness during this epoch. The paper demonstrates that the perceptions of race that were rampant on the imperial periphery were the unique synthesis of evolving gender identities in the Victorian metropole.

Vertically Shifted Mixture Models For Clustering Longitudinal Data By Shape, Brianna C. Heggeseth, Nicholas P. Jewell

U.C. Berkeley Division of Biostatistics Working Paper Series

Longitudinal studies play a prominent role in health, social and behavioral sciences as well as in the biological sciences, economics, and marketing. By following subjects over time, temporal changes in an outcome of interest can be directly observed and studied. An important question concerns the existence of distinct trajectory patterns. One way to determine these distinct patterns is through cluster analysis, which seeks to separate objects (subjects, patients, observational units) into homogeneous groups. Many methods have been adapted for longitudinal data, but almost all of them fail to explicitly group trajectories according to distinct pattern shapes. To fulfill the need …

Smoking Abstinence-Related Expectancies Among American Indians, African Americans, And Women: Potential Mechanisms Of Disparities In Cigarette Use, P. S. Hendricks, J. L. Westmaas, Van M. Ta Park, C. B. Thorne, S. B. Wood, M. R. Baker, M. R. Lawler, M. Webb Hooper, K. L. Delucchi, S. M. Hall

Faculty Publications

Research has documented tobacco-related health disparities by race and gender. Prior research, however, has not examined expectancies about the smoking cessation process (i.e., abstinence-related expectancies) as potential contributors to tobacco-related disparities in special populations. This cross-sectional study compared abstinence-related expectancies between American Indian (n = 87), African American (n = 151), and White (n = 185) smokers, and between women (n = 231) and men (n = 270) smokers. Abstinence-related expectancies also were examined as mediators of race and gender relationships with motivation to quit and abstinence self efficacy. Results indicated that American Indians and African Americans were less likely …

Fuzzy Complex Formation Between The Intrinsically Disordered Prothymosin Α And The Kelch Domain Of Keap1 Involved In The Oxidative Stress Response., Halema Khan, Elio A Cino, Anne Brickenden, Jingsong Fan, Daiwen Yang, Wing-Yiu Choy

Biochemistry Publications

Kelch-like ECH-associated protein 1 (Keap1) is an inhibitor of nuclear factor erythroid 2-related factor 2 (Nrf2), a key transcription factor for cytoprotective gene activation in the oxidative stress response. Under unstressed conditions, Keap1 interacts with Nrf2 in the cytoplasm via its Kelch domain and suppresses the transcriptional activity of Nrf2. During oxidative stress, Nrf2 is released from Keap1 and is translocated into the nucleus, where it interacts with the small Maf protein to initiate gene transcription. Prothymosin α (ProTα), an intrinsically disordered protein, also interacts with the Kelch domain of Keap1 and mediates the import of Keap1 into the nucleus …

The Need To Address Black-Backed Jackal And Caracal Predation In South Africa, David L. Bergman, Ho De Waal, Nico L. Avenant, Michael J. Bodenchuk, Michael C. Marlow, Dale L. Nolte

Wildlife Damage Management Conference

Prior to 1990, the four provincial governments of South Africa had a variety of programs in place to manage predation by black-backed jackals and caracals through lethal and nonlethal management in close cooperation with livestock farmers. During the 1990s the official programmes were phased out due to a multitude of factors including lower predation rates. Today, thousands of livestock (primarily sheep and goats, but also cattle and wildlife) are lost each day in South Africa due to black-backed jackal and caracal predation. The actual numbers are not known because not all losses are accounted or reported. It also does not …

Beyond Surveillance: Towards The Management Of Feral Swine Diseases, Michael J. Bodenchuk, Brian Mesenbrink, Bruce Leland

Wildlife Damage Management Conference

Feral swine distribution and densities are greatest in Texas and related swine disease issues have emerged in a number of fronts. Beyond the standard surveillance protocols, the Texas Cooperative Wildlife Service program has initiated several feral swine projects to identify, contain or eliminate feral swine diseases and pathogens. This paper discusses these projects, the supportive data to quantify dis-ease management and the near-term trend in disease management.

Influence Of Double-Crested Cormorants On Food Web Productivity In Freshwater Ponds, Austin Butts, Kayla Frady, Kate L. Sheehan, Ron J. Johnson, Greg K. Yarrow

Wildlife Damage Management Conference

Conflicts with wildlife are often based on the perceptions and concerns of citizens, industries, and managers. The gregarious nature of Double-crested Cormorants (Phalacrocorax auritus; DCCO) makes their colonies highly conspicuous. Their feeding habits on forage and commercially important fishes have incited a human/wildlife conflict with this species. Colonies re-use roosting and nesting sites. In these areas guano deposits accumulate and are released into the environment where they have the potential to alter the food web through changes in productivity. This alteration can ultimately change the composition, abundance, and condition of fishery resources.

Identification Of Putative Origins Of Introduced Pigs In Indiana Using Nuclear Microsatellite Markers And Oral History, Joe N. Caudell, Blake E. Mccann, Robert A. Newman, Rebecca B. Simmons, Steven E. Backs, Brandon S. Schmit, Richard A. Sweitzer

Wildlife Damage Management Conference

Feral swine (Sus scrofa) have been introduced throughout North America from various global locations (Mayer and Brisbin 1991). In some cases, sources for feral swine are provided through historical records, but for many newly established populations, the origins of feral swine are not known. Understanding the origins and dispersal patterns of feral swine is an important management consideration, because of the introduction of diseases to new locations, for prosecution of individuals who have trans-ported feral swine across state lines, and for allocating swine removal efforts appropriately to address swine translocations within a state or a management area.

Managing Raptors To Reduce Wildlife Strikes At Chicago’S O’Hare International Airport, Travis L. Guerrant, Craig K. Pullins, Scott F. Beckerman, Brian E. Washburn

Wildlife Damage Management Conference

Wildlife-aircraft collisions (wildlife strikes) have increased nationally over the past 22 years; denoted in the National Wildlife Strike Database that has been maintained by the Federal Aviation Administration (FAA) since 1990. Increasing wildlife populations and air traffic coupled with quieter, faster aircraft create a significant risk to aviation safety; the cost to the civil aviation industry is an estimated $718 million dollars annually. USDA/APHIS/Wildlife Services provides technical and direct assistance to over 785 airports and airbases around the United States, including Chicago’s O’Hare International Airport (ORD). At ORD, raptors are the most commonly struck bird guild accounting for 25% of …

Wastewater Treatment Wetlands: Potential Hazardous Wildlife Attractants For Airports, Robert A. Kennamer, I. Lehr Brisbin Jr., Carol S. Eldridge, D. Allen Saxon Jr.

Wildlife Damage Management Conference

Wetlands constructed for the treatment of urban wastewater effluent have gained worldwide popularity in recent decades. Placement of such wetlands near airports however, is strongly discouraged by the U.S. Federal Aviation Administration, other national airport authorities, and the International Bird Strike Committee because they attract birds that may increase strike risks for aircraft. Despite recognition of this and other wildlife hazards to aircraft and efforts implemented to limit such land-use activities near airports, validated methods are still urgently needed to mitigate wildlife hazards on or near airports because bird populations and bird-aircraft strikes in the U.S. and elsewhere around the …

The National Wildlife Control Training Program, Stephen M. Vantassel, Scott E. Hygnstrom, Paul D. Curtis, Raj Smith

Wildlife Damage Management Conference

Although state wildlife agencies allow private individuals to perform wildlife control services, only 14 have meaningful and appropriate training requirements for licensing wildlife control operators (WCOs). We developed a training program called the National Wildlife Control Training Program (NWCTP) to cover the fundamental skills and knowledge required by WCOs. This article explains the development of the NWCTP, its content, and the opportunity it provides for states and federal agencies, private companies, and individuals to train WCOs.

Efficacy Of Two Raccoon Eviction Fluids, Stephen M. Vantassel, Scott E. Hygnstrom, Tim L. Hiller

Wildlife Damage Management Conference

According to surveys of wildlife control operators (WCO), problems with raccoons (Procyon lotor) consistently rank among the top complaints for property owners. Among the more serious behaviors of female raccoons is their propensity to invade human-occupied structures to raise young. Distressed property owners frequently respond using lethal means, either on their own or through hiring WCOs. Even if live-captured and legally released, the handling of raccoons may result in injuries and potentially cause females to abandon young. Eviction fluids, developed in the early 1990s, are designed to smell like a male raccoon and therefore cause a nursing raccoon …
