The leading genetic cause of infant mortality is spinal muscular atrophy (SMA), a clinically and genetically heterogeneous group of disorders. Previously we described a domestic cat model of autosomal recessive, juvenile-onset SMA similar to human SMA type III. Here we report results of a whole-genome scan for linkage in the feline SMA pedigree using recently developed species-specific and comparative mapping resources. We identified a novel SMA gene candidate, LIX1, in an ~140-kb deletion on feline chromosome A1q in a region of conserved synteny to human chromosome 5q15. Though LIX1 function is unknown, the predicted secondary structure is compatible with …

Design Of Piezoresistive Mems Force And Displacement Sensors, Tyler Lane Waterfall Sep 2006

Design Of Piezoresistive Mems Force And Displacement Sensors, Tyler Lane Waterfall

Theses and Dissertations

MEMS (MicroElectroMechanical Systems) sensors are used in acceleration, flow, pressure and force sensing applications on the micro and macro levels. Much research has focused on improving sensor precision, range, reliability, and ease of manufacture and operation. One exciting possibility for improving the capability of micro sensors lies in exploiting the piezoresistive properties of silicon, the material of choice in many MEMS fabrication processes. Piezoresistivity—the change of electrical resistance due to an applied strain—is a valuable material property of silicon due to its potential for high signal output and on-chip and feedback-control possibilities. However, successful design of piezoresistive micro sensors requires …

The Nature Of The "In-Between" In D.W. Winnicott's Concept Of Transitional Space And In Martin Buber's Das Zwischenmenschliche, Laura Praglin Sep 2006

The Nature Of The "In-Between" In D.W. Winnicott's Concept Of Transitional Space And In Martin Buber's Das Zwischenmenschliche, Laura Praglin

UNIversitas: Journal of Research, Scholarship, and Creative Activity

Martin Buber (1878-1965), German Jewish social philosopher and theologian, and D.W. Winnicott (1896-1971), British pediatrician and psychoanalyst, portray in vibrant detail the reality of the “in-between”. Although contemporaries, they were separated by country and profession, and did not know each other. Yet both set forth in their writings remarkably complementary views concerning “in-between space”--the transitional area, to Winnicott, or das Zwischenmenschliche to Buber. This is a meeting-ground of potentiality and authenticity, located neither within the self nor in the world of political and economic affairs. In this space, one finds the most authentic and creative aspects of our personal and …

Non-Standard Structure Flow Measurement Evaluation Using The Flow Rate Indexing Procedure - Qip, Stuart W. Styles, Bryan Busch, Daniel J. Howes, Marcus Cardenas Sep 2006

Non-Standard Structure Flow Measurement Evaluation Using The Flow Rate Indexing Procedure - Qip, Stuart W. Styles, Bryan Busch, Daniel J. Howes, Marcus Cardenas

BioResource and Agricultural Engineering

This report details the proper installation and calibration techniques for hydroacoustic meters. The calibration procedure developed as part of this study is called the Flow Rate Indexing Procedure (QIP). The QIP can be competed by a professional technician with a boat-mounted Acoustic Doppler Profiler (ADP) or a standard current meter. Once the QIP has been used to properly calibrate a hydroacoustic flow meter, the device can then measure and record the flow rate and volume in a channel to within +/- 6% of actual values.

Poverty Analysis Using An International Cross-Country Demand System, John Cranfield, Paul Preckel, Thomas Hertel Sep 2006

Poverty Analysis Using An International Cross-Country Demand System, John Cranfield, Paul Preckel, Thomas Hertel

GTAP Working Papers Archive

This paper proposes a new method for ex ante analysis of the poverty impacts arising from policy reforms. Three innovations underlie this approach. The first is the estimation of a global demand system using a combination of micro-data from household surveys, and macro-data from the International Comparisons Project. Estimation is undertaken in a manner that reconciles these two sources of information, explicitly recognizing that per capita national demands are an aggregation of the disaggregated, individual household demands. The second innovation relates to a methodology for post-estimation calibration of the global demand system, giving rise to country specific demand systems and …

Mining Rdf Metadata For Generalized Association Rules, Tao Jiang, Ah-Hwee Tan Sep 2006

Mining Rdf Metadata For Generalized Association Rules, Tao Jiang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

In this paper, we present a novel frequent generalized pattern mining algorithm, called GP-Close, for mining generalized associations from RDF metadata. To solve the over-generalization problem encountered by existing methods, GP-Close employs the notion of generalization closure for systematic over-generalization reduction. Empirical experiments conducted on real world RDF data sets show that our method can substantially reduce pattern redundancy and perform much better than the original generalized association rule mining algorithm Cumulate in term of time efficiency.

Discovering Image-Text Associations For Cross-Media Web Information Fusion, Tao Jiang, Ah-Hwee Tan Sep 2006

Discovering Image-Text Associations For Cross-Media Web Information Fusion, Tao Jiang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

The diverse and distributed nature of the information published on the World Wide Web has made it difficult to collate and track information related to specific topics. Whereas most existing work on web information fusion has focused on multiple document summarization, this paper presents a novel approach for discovering associations between images and text segments, which subsequently can be used to support cross-media web content summarization. Specifically, we employ a similarity-based multilingual retrieval model and adopt a vague transformation technique for measuring the information similarity between visual features and textual features. The experimental results on a terrorist domain document set …

An Instance-Based Structured Object Oriented Method For Co-Analysis/Co-Design Of Concurrent Embedded Systems, Matt Ryan, Xiaoqing Frank Liu, Bruce M. Mcmillin, Ying Cheng, Sule Simsek Sep 2006

An Instance-Based Structured Object Oriented Method For Co-Analysis/Co-Design Of Concurrent Embedded Systems, Matt Ryan, Xiaoqing Frank Liu, Bruce M. Mcmillin, Ying Cheng, Sule Simsek

Computer Science Faculty Research & Creative Works

The current object-oriented class-based approaches to hardware/software co-analysis/co-design of embedded systems are limited in their abilities to properly capture the structure of individual instances of hardware and software components and their interactions. This paper discusses a methodology to extend a structured objectoriented hardware/software co-design methodology based on the High Order Object-oriented Modeling Technique (HOOMT) to incorporate instance-based object and behavioral models. The instance-based structured object-oriented methodology will enable description of a system's structure based on individual instances of hardware and software components and specification of the interactions among them. In addition, lattices are introduced to specify the concurrent behavior of …

Theories Of Asbestos Litigation Cost - Why Two Decades Of Procedural Reform Have Failed To Reduce Claimants' Expenses, Jeffrey M. Davidson Sep 2006

Theories Of Asbestos Litigation Cost - Why Two Decades Of Procedural Reform Have Failed To Reduce Claimants' Expenses, Jeffrey M. Davidson

Nevada Law Journal

In twenty years of asbestos litigation, procedural reforms at all levels of the civil litigation system have failed to reduce plaintiffs' attorneys'fees. The result has been dramatic undercompensation of asbestos tort victims. This paper attepts to explain this remarkable fact using economic methodology. The paper offers three theories: First, that the continuing difficulty of assessing causation in asbestos and other mass tort cases predictably impedes the efforts of procedural reform to reduce costs; second, that changes in defendant and insurer risk attitudes have generated costly litigation; third, that collusion of plaintiffs' attorneys to maintain prices cannot be ruled out. Each …

Holographic Capture Of Femtosecond Pulse Propagation, Martin Centurion, Ye Pu, Demetri Psaltis Sep 2006

Holographic Capture Of Femtosecond Pulse Propagation, Martin Centurion, Ye Pu, Demetri Psaltis

Martin Centurion Publications

We have implemented a holographic system to study the propagation of femtosecond laser pulses with high temporal (150 fs) and spatial resolutions (4 μm). The phase information in the holograms allows us to reconstruct both positive and negative index changes due to the Kerr nonlinearity (positive) and plasma formation (negative), and to reconstruct three-dimensional structure. Dramatic differences were observed in the interaction of focused femtosecond pulses with air, water, and carbon disulfide. The air becomes ionized in the focal region, while in water long plasma filaments appear before the light reaches a tight focus. In contrast, in carbon disulfide the …

Deep-Water Antipatharians: Proxies Of Environmental Change, B. Williams, M.J. Risk, S.W. Ross, K.J. Sulak Sep 2006

Deep-Water Antipatharians: Proxies Of Environmental Change, B. Williams, M.J. Risk, S.W. Ross, K.J. Sulak

United States Geological Survey: Staff Publications

Deep-water (307–697 m) antipatharian (black coral) specimens were collected from the southeastern continental slope of the United States and the north-central Gulf of Mexico. The sclerochronology of the specimens indicates that skeletal growth takes place by formation of concentric coeval layers. We used 210Pb to estimate radial growth rate of two specimens, and to establish that they were several centuries old. Bands were delaminated in KOH and analyzed for carbon and nitrogen stable isotopes. Carbon values ranged from _16.4‰ to _15.7‰; the oldest specimen displayed the largest range in values. Nitrogen values ranged from 7.7‰ to 8.6‰. …

Data Report: Dissolved Sulfide Concentration And Sulfur Isotopic Composition Of Sulfide And Sulfate In Pore Waters, Odp Leg 204, Hydrate Ridge And Vicinity, Cascadia Margin, Offshore Oregon, Walter S. Borowski Sep 2006

Data Report: Dissolved Sulfide Concentration And Sulfur Isotopic Composition Of Sulfide And Sulfate In Pore Waters, Odp Leg 204, Hydrate Ridge And Vicinity, Cascadia Margin, Offshore Oregon, Walter S. Borowski

EKU Faculty and Staff Scholarship

We report dissolved sulfide sulfur concentrations and the sulfur isotopic composition of dissolved sulfate and sulfide in pore waters from sediments collected during Ocean Drilling Program Leg 204. Porewater sulfate is depleted rapidly as the depth to the sulfate/methane interface (SMI) occurs between 4.5 and 11 meters below seafloor at flank and basin locations. Dissolved sulfide concentration reaches values as high as 11.3 mM in Hole 1251E. Otherwise, peak sulfide concentrations lie between 3.2 and 6.1 mM and occur immediately above the SMI. The sulfur isotopic composition of interstitial sulfate generally becomes enriched in 34 S with increasing sediment depth. …

Microbial Growth And Biofilm Formation In Geologic Media Is Detected With Complex Conductivity Measurements, Caroline A. Davis, Estella A. Atekwana, Eliot A. Atekwana, Lee D. Slater, Silvia Rossbach, Melanie R. Mormile Sep 2006

Microbial Growth And Biofilm Formation In Geologic Media Is Detected With Complex Conductivity Measurements, Caroline A. Davis, Estella A. Atekwana, Eliot A. Atekwana, Lee D. Slater, Silvia Rossbach, Melanie R. Mormile

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Complex conductivity measurements (0.1-1000 Hz) were obtained from biostimulated sand-packed columns to investigate the effect of microbial growth and biofilm formation on the electrical properties of porous media. Microbial growth was verified by direct microbial counts, pH measurements, and environmental scanning electron microscope imaging. Peaks in imaginary (interfacial) conductivity in the biostimulated columns were coincident with peaks in the microbial cell concentrations extracted from sands. However, the real conductivity component showed no discernible relationship to microbial cell concentration. We suggest that the observed dynamic changes in the imaginary conductivity (σ″) arise from the growth and attachment of microbial cells and …

An Event-Driven Approach To Computerizing Clinical Guidelines Using Xml, Bing Wu, Essam Mansour, Kudakwashe Dube, Jianxin Li Sep 2006

An Event-Driven Approach To Computerizing Clinical Guidelines Using Xml, Bing Wu, Essam Mansour, Kudakwashe Dube, Jianxin Li

Conference Papers

Clinical events form the basis of patient care practice. Their computerization is an important aid to the work of clinicians. Clinical guidelines or protocols direct clinicians and patients on when and how to handle clinical problems. Thus, clinical guidelines are an encapsulation of clinical events. Hence, an event-driven approach to computerizing the management of clinical guidelines is worthy of investigation. In our framework, called SpEM, the main clinical guideline management dimensions are specification, execution, and manipulation. This paper presents an event-driven approach, within the context of the SpEM framework, to manage clinical guidelines. The event-driven approach is based on the …

Crystal Habits And Magnetic Microstructures Of Magnetosomes In Coccoid Magnetotactic Bacteria, Ulysses Lins, Martha R. Mccartney, Marcos Farina, Richard B. Frankel, Peter R. Buseck

Physics

We report on the application of off-axis electron holography and high-resolution TEM to study the crystal habits of magnetosomes and magnetic microstructure in two coccoid morphotypes of magnetotactic bacteria collected from a brackish lagoon at Itaipu, Brazil. Itaipu-1, the larger coccoid organism, contains two separated chains of unusually large magnetosomes; the magnetosome crystals have roughly square projections, lengths up to 250 nm and are slightly elongated along [111] (width/length ~ 0.9). Itaipu-3 magnetosome crystals have lengths up to 120 nm, greater elongation along [111] (width/length approximately 0.6), and prominent corner facets. The results show that Itaipu-1 and Itaipu-3 magnetosome crystal …

Self-Positioning Smart Buoys, The 'Un-Buoy' Solution: Logistic Considerations Using Autonomous Surface Craft Technology And Improved Communications Infrastructure, Joseph A. Curcio, Philip A. Mcgillivary, Kevin Fall, Andrew Maffei, Kurt Schwehr, Bob Twiggs, Chris Kitts, Phil Ballou Sep 2006

Self-Positioning Smart Buoys, The 'Un-Buoy' Solution: Logistic Considerations Using Autonomous Surface Craft Technology And Improved Communications Infrastructure, Joseph A. Curcio, Philip A. Mcgillivary, Kevin Fall, Andrew Maffei, Kurt Schwehr, Bob Twiggs, Chris Kitts, Phil Ballou

Center for Coastal and Ocean Mapping

Moored buoys have long served national interests, but incur high development, construction, installation, and maintenance costs. Buoys which drift off-location can pose hazards to mariners, and in coastal waters may cause environmental damage. Moreover, retrieval, repair and replacement of drifting buoys may be delayed when data would be most useful. Such gaps in coastal buoy data can pose a threat to national security by reducing maritime domain awareness. The concept of self-positioning buoys has been advanced to reduce installation cost by eliminating mooring hardware. We here describe technology for operation of reduced cost self-positioning buoys which can be used in …

Modes Of Biomineralization Of Magnetite By Microbes, Dennis A. Bazylinski, Richard B. Frankel, Kurt O. Konhauser Sep 2006

Modes Of Biomineralization Of Magnetite By Microbes, Dennis A. Bazylinski, Richard B. Frankel, Kurt O. Konhauser

Physics

Biomineralization processes have traditionally been grouped into two distinct modes; biologically induced mineralization (BIM) and biologically controlled mineralization (BCM). In BIM, microbes cause mineral formation by sorbing solutes onto their cell surfaces or extruded organic polymers and/or releasing reactive metabolites which alter the saturation state of the solution proximal to the cell or polymer surface. Such mineral products appear to have no specific recognized functions. On the other hand, in BCM microbes exert a great degree of chemical and genetic control over the nucleation and growth of mineral particles, presumably because the biominerals produced serve some physiological function. Interestingly, there …

Beliefs About Language Learning Of Foreign Language- Major University Students, Mustapha X. Altan Sep 2006

Beliefs About Language Learning Of Foreign Language- Major University Students, Mustapha X. Altan

Australian Journal of Teacher Education

Beliefs are a central construct in every discipline which deals with human behavior and learning. Teachers’ beliefs influence their consciousness, teaching attitude, teaching methods and teaching policies. Teachers’ beliefs also strongly influence teaching behavior and, finally, learners’ development. The formation of teachers’ educational beliefs in language teaching/learning process will exert an indiscernible effect on forming effective teaching methods and will bring about the improvement of learners’ language learning abilities (Horwitz, 1985). The Beliefs About Language Learning Inventory (BALLI) was administered to a total of 248 foreign language-major university students at five universities. The participants were in the departments of English, …
