Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry Jan 2012

Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry

Speech Pathology and Audiology Faculty Research and Publications

This paper introduces a new method to track articulator movements, specifically jaw position and angle, using 5 degree of freedom (5 DOF) orientation data. The approach uses a quaternion rotation method to accomplish this jaw tracking during speech using a single senor on the mandibular incisor. Data were collected using the NDI Wave Speech Research System for one pilot subject with various speech tasks. The degree of jaw rotation from the proposed approach is compared with traditional geometric calculation. Results show that the quaternion based method is able to describe jaw angle trajectory and gives more accurate and smooth estimation …


Examining The Relationship Between Garlic Mustard (Alliaria Petiolata) And European Earthworms, Alexandra M. Zelles Jan 2012

Examining The Relationship Between Garlic Mustard (Alliaria Petiolata) And European Earthworms, Alexandra M. Zelles

Browse all Theses and Dissertations

Our goal was to characterize the interactive feedback between garlic mustard (Alliaria petiolata) and European earthworm species in southwest Ohio. Earthworm community composition, abundance and biomass were compared between 0.1 m2 plots of garlic mustard, cut-leaved toothwort (Cardamine concatenate), wild ginger (Asarum canadense), or no plant cover. Exotic earthworms were present in the study site. Earthworm abundance and biomass did not correlate with garlic mustard percent cover. There was a greater density of earthworms in the fall than in the spring. Worm abundance differed between garlic mustard and wild ginger plots and cut-leaved …

Nepetalactones From Essential Oil Of Nepeta Cataria Represent A Stable Fly Feeding And Oviposition Repellent, J. J. Zhu, Dennis R. Berkebile, C. E. Dunlap, A. Zhang, D. Boxler, K. Tangtrakulwanich, R. Behle, Frederick P. Baxendale, Gary J. Brewer

Department of Entomology: Faculty Publications

The stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), is one of the most serious pests to livestock. It feeds mainly on cattle and causes significant economic losses in the cattle industry. Standard stable fly control involving insecticides and sanitation is usually costly and often has limited effectiveness. As we continue to evaluate and develop safer fly control strategies, the present study reports on the effectiveness of catnip (Nepeta cataria L.) oil and its constituent compounds, nepetalactones, as stable fly repellents. The essential oil of catnip reduced the feeding of stable flies by >96% in an in vitro bioassay system, …

Using Web-Based Key Character And Classification Instruction For Teaching Undergraduate Students Insect Identification, Douglas A. Golick, Tiffany M. Heng-Moss, Allen L. Steckelberg, David W. Brooks, Leon G. Higley, David Fowler Jan 2012

Using Web-Based Key Character And Classification Instruction For Teaching Undergraduate Students Insect Identification, Douglas A. Golick, Tiffany M. Heng-Moss, Allen L. Steckelberg, David W. Brooks, Leon G. Higley, David Fowler

Department of Entomology: Faculty Publications

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification …


Inter- And Intraspecific Identification Of The Screwworm, Cochliomyia Hominivorax, Using Random Amplified Polymorphic Dna-Polymerase Chain Reaction, Steven R. Skoda, James L. Figarola, Saowaluck Pornkulwat, John E. Foster Jan 2012

Inter- And Intraspecific Identification Of The Screwworm, Cochliomyia Hominivorax, Using Random Amplified Polymorphic Dna-Polymerase Chain Reaction, Steven R. Skoda, James L. Figarola, Saowaluck Pornkulwat, John E. Foster

Department of Entomology: Faculty Publications

The screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), is one of the most devastating arthropod pests of livestock in the Western Hemisphere. Early instars are very difficult to distinguish morphologically from several closely related blow fly species. Random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) markers were developed for identifying C. hominivorax from other wound inhabiting species. Forty decameric primers were screened; nine showed clear reproducible RAPD profiles suitable for distinguishing all life stages of C. hominivorax from 7 other species, including C. macellaria (Fabricius). The results from RAPD-PCR with field-collected samples of unknown first instars agreed with morphological identification that the …


The Soybean Aphid, Aphis Glycines (Hemiptera: Aphididae): Population Dynamics On Edamame Soybeans In Nebraska, Usa, Bamphitlhi Tiroesele, Thomas E. Hunt, Robert J. Wright, Erin E. Blankenship, John E. Foster Jan 2012

The Soybean Aphid, Aphis Glycines (Hemiptera: Aphididae): Population Dynamics On Edamame Soybeans In Nebraska, Usa, Bamphitlhi Tiroesele, Thomas E. Hunt, Robert J. Wright, Erin E. Blankenship, John E. Foster

Department of Entomology: Faculty Publications

Edamame are soybeans harvested at a physiologically immature (R6) stage as a specialty food item for fresh and processed (frozen) markets. The soybean aphid, Aphis glycines Matsumura, is a newly introduced insect pest of soybeans in North America. This field study was to provide baseline information on the impact of A. glycines on the edamame soybean. This study determined the population growth rate of A. glycines on two edamame soybean cultivars, ‘Butterbeans’ and ‘Envy,’ at two planting dates during 2004 and 2005 in Nebraska. Aphid population growth was significantly higher on 'Butterbeans' than on 'Envy' for the first planting date …


Inbreeding-Stress Interactions: Evolutionary And Conservation Consequences, David H. Reed, Charles W. Fox, Laramy S. Enders, Torsten N. Kristensen Jan 2012

Inbreeding-Stress Interactions: Evolutionary And Conservation Consequences, David H. Reed, Charles W. Fox, Laramy S. Enders, Torsten N. Kristensen

Department of Entomology: Faculty Publications

The effect of environmental stress on the magnitude of inbreeding depression has a long history of intensive study. Inbreeding-stress interactions are of great importance to the viability of populations of conservation concern and have numerous evolutionary ramifications. However, such interactions are controversial. Several meta-analyses over the last decade, combined with omic studies, have provided considerable insight into the generality of inbreeding-stress interactions, its physiological basis, and have provided the foundation for future studies. In this review, we examine the genetic and physiological mechanisms proposed to explain why inbreeding-stress interactions occur. We specifically examine whether the increase in inbreeding depression with …


A Comparison Of Dung Beetle (Coleoptera: Scarabaeidae) Attraction To Native And Exotic Mammal Dung, Sean D. Whipple, W. Wyatt Hoback Jan 2012

A Comparison Of Dung Beetle (Coleoptera: Scarabaeidae) Attraction To Native And Exotic Mammal Dung, Sean D. Whipple, W. Wyatt Hoback

Department of Entomology: Faculty Publications

Although the preference of dung beetles (Coleoptera: Scarabaeidae) for specific types and conditions of dung has been given substantial attention, little has been done to investigate the potential effects of exotic mammal introduction for game farms or rewilding projects. We used pitfall traps baited with various native and exotic herbivore, carnivore, and omnivore dung to evaluate dung beetle preference in the Great Plains of North America. Additionally, we analyzed the nutrient quality of each dung type. In total, 9,089 dung beetles from 15 species were captured in 2 yr of sampling. We found significant differences (P < 0.05) in mean dung beetle capture among omnivore, herbivore, and carnivore dung as well as differences in individual species preference for dung type. Omnivore dung was the most attractive with chimpanzee and human dung having the highest mean capture (291.1 ± 27.6 and 287.5 ± 28.5 respectively). Carrion also was highly attractive with a mean of 231.9 ± 20.6 beetles per trap (N = 8). …


Pheromone–Mediated Mating Disruption In The Millet Stem Borer, Coniesta Ignefusalis (Lepidoptera: Pyralidae), Ousmane Youm, Yacouba Maliki, David R. Hall, Dudley I. Farman, John E. Foster Jan 2012

Pheromone–Mediated Mating Disruption In The Millet Stem Borer, Coniesta Ignefusalis (Lepidoptera: Pyralidae), Ousmane Youm, Yacouba Maliki, David R. Hall, Dudley I. Farman, John E. Foster

Department of Entomology: Faculty Publications

The millet stem borer, Coniesta ignefusalis Hampson (Lepidoptera: Pyralidae), is a major pest of pearl millet in the Sahelian region of Africa. The female sex pheromone has been identified and synthesized, and previous research had shown that the synthetic pheromone could cause high levels of reproductive communication disruption in small plots when released at rates of 640 mg/ha/day, using PVC resin formulation renewed every seven days to maintain efficiency. In the present research, in experiments in farmers’ fields in Niger, 86.8% (SE = 2.6%) communication disruption was achieved when polyethylene vials loaded with 0.5 mg pheromone at 400 dispensers/ha were …


Sensing Through The Continent: Towards Monitoring Migratory Birds Using Cellular Sensor Networks, David Anthony, William P. Bennett, Mehmet C. Vuran, Matthew B. Dwyer, Sebastian Elbaum, Anne Lacy, Mike Engels, Walter Wehtje Jan 2012

Sensing Through The Continent: Towards Monitoring Migratory Birds Using Cellular Sensor Networks, David Anthony, William P. Bennett, Mehmet C. Vuran, Matthew B. Dwyer, Sebastian Elbaum, Anne Lacy, Mike Engels, Walter Wehtje

School of Computing: Conference and Workshop Papers

This paper presents CraneTracker, a novel sensor platform for monitoring migratory birds. The platform is designed to monitor Whooping Cranes, an endangered species that conducts an annual migration of 4, 000 km between southern Texas and north-central Canada. CraneTracker includes a rich set of sensors, a multi-modal radio, and power control circuitry for sustainable, continental-scale information delivery during migration. The need for large-scale connectivity motivates the use of cellular technology in low-cost sensor platforms augmented by a low-power transceiver for ad-hoc connectivity. This platform leads to a new class of cellular sensor networks (CSNs) for time-critical and mobile sensing applications. …

Department of Electrical and Computer Engineering: Faculty Publications

Inexpensive, high-throughput, low maintenance systems for precise temporal and spatial measurement of mouse home cage behavior (including movement, feeding, and drinking) are required to evaluate products from large scale pharmaceutical design and genetic lesion programs. These measurements are also required to interpret results from more focused behavioral assays. We describe the design and validation of a highly-scalable, reliable mouse home cage behavioral monitoring system modeled on a previously described, one-ofa- kind system [1]. Mouse position was determined by solving static equilibrium equations describing the force and torques acting on the system strain gauges; feeding events were detected by a photobeam …


(Im)Mobile Metaphors: Toward An Intersectional Rhetorical History, Carly S. Woods Jan 2012

(Im)Mobile Metaphors: Toward An Intersectional Rhetorical History, Carly S. Woods

Department of Communication Studies: Faculty Publications

Metaphors not only "structure our experience" but "by organizing reality in particular ways, our selected metaphors also prescribe how we are to act." As the opening chapter of this volume notes, feminist scholars have long grappled with the figurative language of intersectionality in order to find the conceptual framing that best accounts for varied relationships between power, oppression, and privilege. Similarly, rhetorical historians have an obligation to think critically about the metaphors we use. One cluster of metaphors, in particular, characterizes both intersectional and rhetorical-historical research: the spatial and geographic. Moreover, critiques of both research approaches essentially point to the …


Genesis In Hyperreality: Legitimizing Disingenuous Controversy At The Creation Museum, Casey Ryan Kelly, Kristen E. Hoerl Jan 2012

Genesis In Hyperreality: Legitimizing Disingenuous Controversy At The Creation Museum, Casey Ryan Kelly, Kristen E. Hoerl

Department of Communication Studies: Faculty Publications

This essay analyzes the argumentative structure of the “Answers in Genesis” ministry’s Creation Museum in Petersburg, Kentucky. Founded by a $27 million grant, the 70,000-square-foot museum appropriates the stylistic and authoritative signifiers of natural history museums, complete with technically proficient hyperreal displays and modern curatorial techniques. In this essay, we argue that the museum provides a culturally authoritative space in which Young Earth Creationists can visually craft the appearance that there is an ongoing scientific controversy over matters long settled in the scientific community (evolution), or what scholars call a disingenuous or manufactured controversy. We analyze the displays and layout …

Green Tea As An Agricultural Based Health Promoting Food: The Past Five To Ten Years, Qin-Yin Shi, Vicki Schlegel

Department of Food Science and Technology: Faculty Publications

The consumption of tea originated in ancient China over 4000 years ago and is currently the second most popular beverage in the world after water. Tea is an aromatic beverage prepared by pouring hot water over cured leaves of the Camellia sinensis plant. The link between tea intake, most notably green tea, and health has resulted in intense research on the components responsible for preventing the onset of several chronic diseases, including atherosclerosis, cancer, obesity and diabetes. In particular, the high levels of chemically diverse phenols (e.g., phenolic acids, flavonoids) present in tea exhibit potent protective properties against many of …

Atherosclerosis is intimately coupled to blood flow by the presence of predilection sites. The coupling is through mechanotransduction of endothelial cells and approximately 2000 gene are associated with this process. This paper describes a new platform to study and identify new signalling pathways in endothelial cells covering an atherosclerotic plaque. The identified networks are synthesized in primary cells to study their reaction to flow. This synthetic approach might lead to new insights and drug targets.

Usability Assessment Of Two Different Control Modes For The Master Console Of A Laparoscopic Surgical Robot, Xiaoli Zhang, Carl A. Nelson, Dmitry Oleynikov

Department of Mechanical and Materials Engineering: Faculty Publications

The objective of this study is to evaluate potential interface control modes for a compact fourdegree- of-freedom (4-DOF) surgical robot. The goal is to improve robot usability by incorporating a sophisticated haptics-capable interface. Two control modes were developed using a commercially available haptic joystick: (1) a virtually point-constrained interface providing an analog for constrained laparoscopic motion (3-DOF rotation and 1-DOF translation), and (2) an unconstrained Cartesian input interface mapping more directly to the surgical tool tip motions. Subjects (n = 5) successfully performed tissue identification and manipulation tasks in an animal model in point-constrained and unconstrained control modes, respectively, with …

Development Of Camera Technology For Monitoring Nests, W. Andrew Cox, M. Shane Pruett, Thomas J. Benson, Scott J. Chiavacci, Frank R. Thompson Iii

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Photo and video technology has become increasingly useful in the study of avian nesting ecology. However, researchers interested in using camera systems are often faced with insufficient information on the types and relative advantages of available technologies. We reviewed the literature for studies of nests that used cameras and summarized them based on study objective and the type of technology used. We also designed and tested two video systems that we used for three nest predator and behavioral studies. We found 327 studies that recorded 255 bird species spanning 19 orders. Cameras were most commonly used to study nest predators …


Knowledge Gained From Video-Monitoring Grassland Passerine Nests, P. J. Pietz, D.A. Granfors, C.A. Ribic, F. R. Thompson Jan 2012

Knowledge Gained From Video-Monitoring Grassland Passerine Nests, P. J. Pietz, D.A. Granfors, C.A. Ribic, F. R. Thompson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In the mid-1990s, researchers began to adapt miniature cameras to video-record activities :rt cryptic passerine nests in grasslands. In the subsequent decade, use of these video surveillance systems spread dramatically, leading to major strides in our knowledge of nest predation and nesting ecology of many species. Studies using video nest surveillance have helped overturn or substantiate many long-standing assumptions and provided insights on a wide range of topics. For example, researchers using video data have (1) identified an extensive and highly dynamic predator community in grasslands that varies both temporally (e.g., by time of day, nest age, season, year) and …


Hatching And Fledging Times From Grassland Passerine Nests, Pamela J. Pietz, D.A. Granfors, Todd Grant Jan 2012

Hatching And Fledging Times From Grassland Passerine Nests, Pamela J. Pietz, D.A. Granfors, Todd Grant

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Accurate estimates of fledging age are needed in field studies to avoid inducing premature fledging or missing the fledging event. Both may lead to misinterpretation of nest fate. Correctly assessing nest fate and length of the nestling period can be critical for accurate calculation of nest survival rates. For researchers who mark nestlings, knowing the age at which their activities may cause young to leave nests prematurely could prevent introducing bias to their studies. We estimated fledging ages from grassland passerine nests monitored from hatching through fledging with miniature video cameras in North Dakota and Minnesota during 1996-2001. We compared …


Conservation Implications When The Nest Predators Are Known, Frank Thompson, C.A. Ribic Jan 2012

Conservation Implications When The Nest Predators Are Known, Frank Thompson, C.A. Ribic

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Conservation and management of passerines has largely focused on habitat manipulation or restoration because the natural communities on which these birds depend have been destroyed and fragmented. However, productivity is another important aspect of avian conservation, and nest predation can be a large source of nesting mortality for passerines. Recent studies using video surveillance to identify nest predators allow researchers to start evaluating what methods could be used to mitigate nest predation to help passerines of conservation concern. From recent studies, we identified latitudinal and habitat-related patterns in the importance of predator groups that depredate passerine nests. We then reviewed …


Wolf Population Dynamics In The U.S. Northern Rocky Mountains Are Affected By Recruitment And Human-Caused Mortality, Justin A. Gude, Michael S. Mitchell, Robin E. Russell, Carolyn A. Sime, L. David Mech, Robert R. Ream Jan 2012

Wolf Population Dynamics In The U.S. Northern Rocky Mountains Are Affected By Recruitment And Human-Caused Mortality, Justin A. Gude, Michael S. Mitchell, Robin E. Russell, Carolyn A. Sime, L. David Mech, Robert R. Ream

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Reliable analyses can help wildlife managers make good decisions, which are particularly critical for controversial decisions such as wolf (Canis lupus) harvest. Creel and Rotella (2010) recently predicted substantial population declines in Montana wolf populations due to harvest, in contrast to predictions made by Montana Fish, Wildlife and Parks (MFWP). We replicated their analyses considering only those years in which field monitoring was consistent, and we considered the effect of annual variation in recruitment on wolf population growth. Rather than assuming constant rates, we used model selection methods to evaluate and incorporate models of factors driving recruitment and …


Modeling Broad-Scale Patterns Of Avian Species Richness Across The Midwestern United States With Measures Of Satellite Image Texture, Patrick D. Culbert, Volker C. Radeloff, Véronique St-Louis, Curtis H. Flather, Chadwick D. Rittenhouse, Thomas P. Albright, Anna M. Pidgeon Jan 2012

Modeling Broad-Scale Patterns Of Avian Species Richness Across The Midwestern United States With Measures Of Satellite Image Texture, Patrick D. Culbert, Volker C. Radeloff, Véronique St-Louis, Curtis H. Flather, Chadwick D. Rittenhouse, Thomas P. Albright, Anna M. Pidgeon

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Avian biodiversity is threatened, and in order to prioritize limited conservation resources and conduct effective conservation planning a better understanding of avian species richness patterns is needed. The use of image texture measures, as a proxy for the spatial structure of land cover and vegetation, has proven useful in explaining patterns of avian abundance and species richness. However, prior studies that modeled habitat with texture measures were conducted over small geographical extents and typically focused on a single habitat type. Our goal was to evaluate the performance of texture measures over broad spatial extents and across multiple habitat types with …
