Graph-Based Weakly-Supervised Methods For Information Extraction & Integration, Partha P. Talukdar 2010 University of Pennsylvania

Graph-Based Weakly-Supervised Methods For Information Extraction & Integration, Partha P. Talukdar

Departmental Papers (CIS)

The variety and complexity of potentially-related data resources available for querying --- webpages, databases, data warehouses --- has been growing ever more rapidly. There is a growing need to pose integrative queries across multiple such sources, exploiting foreign keys and other means of interlinking data to merge information from diverse sources. This has traditionally been the focus of research within Information Extraction (IE) and Information Integration (II) communities, with IE focusing on converting unstructured sources into structured sources, and II focusing on providing a unified view of diverse structured data sources. However, most of the current IE and II methods, …


The Lick-Carnegie Exoplanet Survey: A Saturn-Mass Planet In The Habitable Zone Of The Nearby M4v Star Hip 57050, Nader Haghighipour, Steve Vogt, R. Paul Butler, Eugenio J. Rivera, Gregory Laughlin, Stefano Meschiari, Gregory W. Henry 2010 University of Hawaii, Manoa

The Lick-Carnegie Exoplanet Survey: A Saturn-Mass Planet In The Habitable Zone Of The Nearby M4v Star Hip 57050, Nader Haghighipour, Steve Vogt, R. Paul Butler, Eugenio J. Rivera, Gregory Laughlin, Stefano Meschiari, Gregory W. Henry

Information Systems and Engineering Management Research Publications

Precision radial velocities (RV) from Keck/HIRES reveal a Saturn-mass planet orbiting the nearby M4V star HIP 57050. The planet has a minimum mass of Msin i ∼ 0.3 MJ, an orbital period of 41.4 days, and an orbital eccentricity of 0.31. V-band photometry reveals a clear stellar rotation signature of the host star with a period of 98 days, well separated from the period of the RV variations and reinforcing a Keplerian origin for the observed velocity variations. The orbital period of this planet corresponds to an orbit in the habitable zone of HIP 57050, with an expected planetary temperature …


Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie 2010 Georgia State University

Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie

Geosciences Theses

The Pozzolane Rosse ignimbrite [PR] (457±4 ka) in the Alban Hills Volcanic District, Rome, Italy was exposed ~ 40 ka prior to a subsequent volcanic event which coverd it entirely. XRF, XRD, and clay separation results from PR samples from INGV and CA1 boreholes and Castel di Leva quarry show evidence of paleopedogenesis. All locations display loss of base cations, loss of K is consistent with XRD datat showing dissolution or alteration of leucite to analcime. Accumulation of Al and high L.O.I. support XRD evidence of 1:1 clay species at upper depth. Data suggest alteration extent can be determined by …


Projections And Idempotents With Fixed Diagonal And The Homotopy Problem For Unit Tight Frames, Julien Giol, Leonid V. Kovalev, David Larson, Nga Nguyen, James E. Tener 2010 Bucknell University

Projections And Idempotents With Fixed Diagonal And The Homotopy Problem For Unit Tight Frames, Julien Giol, Leonid V. Kovalev, David Larson, Nga Nguyen, James E. Tener

Mathematics - All Scholarship

We investigate the topological and metric structure of the set of idempotent operators and projections which have prescribed diagonal entries with respect to a fixed orthonormal basis of a Hilbert space. As an application, we settle some cases of conjectures of Larson, Dykema, and Strawn on the connectedness of the set of unit-norm tight frames.


Chirality Dependence Of The K-Momentum Dark Excitons In Carbon Nanotubes, Patrick M. Vora, X Tu, Eugene J. Mele, M Zheng, James M. Kikkawa 2010 University of Pennsylvania

Chirality Dependence Of The K-Momentum Dark Excitons In Carbon Nanotubes, Patrick M. Vora, X Tu, Eugene J. Mele, M Zheng, James M. Kikkawa

Department of Physics Papers

Using a collection of 12 semiconducting carbon-nanotube samples, each highly enriched in a single chirality, we study the chirality dependence of the K-momentum dark singlet exciton using phonon sideband optical spectroscopy. Measurements of bright absorptive and emissive sidebands of this finite momentum exciton identify its energy as 20–38 meV above the bright singlet exciton, a separation that exhibits systematic dependencies on tube diameter, 2n+m family, and chiral index. We present calculations that explain how chiral angle dependence in this energy separation relates to the Coulomb exchange interaction and elaborate the dominance of the KAA; …


Censoring Maps In Google China? Visual Analysis Through Foucault't Power/Knowledge, Zhanar Karimbayeva 2010 Georgia State University

Censoring Maps In Google China? Visual Analysis Through Foucault't Power/Knowledge, Zhanar Karimbayeva

Geosciences Theses

This thesis explores aspects of map censorship in Google China through a theoretical framework based on Foucault’s power/knowledge. Comparing results of content analysis of maps in Google Ditu in Google China and Google Maps in Google Dot Com, the thesis analyzes the degree of censorship of maps in the Google geoweb. My findings are a higher density of labeling in Google Ditu in comparison with Google Maps, the absence of VGI in Google Ditu, the limitation of zoom level at Google Ditu, and the absence of Street View in China. This thesis suggests possible explanations to differences in map information …

Bifurcations Of Traveling Wave Solutions For An Integrable Equation, Jibin Li, Zhijun Qiao 2010 Zhejiang Normal University

Bifurcations Of Traveling Wave Solutions For An Integrable Equation, Jibin Li, Zhijun Qiao

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

This paper deals with the following equation mt= 1/2 1/mk xxx− 1/2 1/mk x, which is proposed by Z. J. Qiao J. Math. Phys. 48, 082701 2007 and Qiao and Liu Chaos, Solitons Fractals 41, 587 2009. By adopting the phase analysis method of planar dynamical systems and the theory of the singular traveling wave systems to the traveling wave solutions of the equation, it is shown that for different k, the equation may have infinitely many solitary wave solutions, periodic wave solutions, kink/antikink wave solutions, cusped solitary wave solutions, and breaking loop solutions. We discuss in a detail the …

Nima Rahbar

This paper presents the results of a combined experimental and theoretical study of microstructure and thermal shock resistance of an aluminosilicate ceramic. Shock-induced crack growth is studied in sintered structures produced from powders with different particle size ranges. The underlying crack/microstructure interactions and toughening mechanisms are elucidated via scanning electron microscopy (SEM). The resulting crack-tip shielding levels (due to viscoelastic crack bridging) are estimated using fracture mechanics concepts. The implications of the

Local Charging Behavior On Gan Surfaces, Josephus Ferguson 2010 Virginia Commonwealth University

Local Charging Behavior On Gan Surfaces, Josephus Ferguson

Theses and Dissertations

Gallium nitride is an important III-V semiconductor which is used in many optoelectronic and high-frequency devices. The nature of the GaN surface and its electrical characteristics can impact the performance of such devices. In this study, several GaN surfaces are locally charged using an atomic force microscope, and then subsequently studied by measuring the surface potential with scanning Kelvin probe microscopy (SKPM). The charging and discharging behavior of the surface appears to be strongly influenced by surface preparation and the presence of a surface oxide layer. If a substantial oxide layer exists, then both positive and negative charging is possible …


Synergy Of Adaptive Thresholds And Multiple Transmitters In Free-Space Optical Communication, James A. Louthain, Jason D. Schmidt 2010 Air Force Institute of Technology

Synergy Of Adaptive Thresholds And Multiple Transmitters In Free-Space Optical Communication, James A. Louthain, Jason D. Schmidt

Faculty Publications

Laser propagation through extended turbulence causes severe beam spread and scintillation. Airborne laser communication systems require special considerations in size, complexity, power, and weight. Rather than using bulky, costly, adaptive optics systems, we reduce the variability of the received signal by integrating a two-transmitter system with an adaptive threshold receiver to average out the deleterious effects of turbulence. In contrast to adaptive optics approaches, systems employing multiple transmitters and adaptive thresholds exhibit performance improvements that are unaffected by turbulence strength. Simulations of this system with on-off-keying (OOK) showed that reducing the scintillation variations with multiple transmitters improves the performance of …


Image Segmentation And Analysis For Automated Classification Of Traumatic Pelvic Injuries, Simina Vasilache 2010 Virginia Commonwealth University

Image Segmentation And Analysis For Automated Classification Of Traumatic Pelvic Injuries, Simina Vasilache

Theses and Dissertations

In the past decades, technical advances have allowed for the collection and storage of more types and larger quantities of medical data. The increase in the volume of existing medical data has increased the need for processing and analyzing such data. Medical data holds information that is invaluable for diagnostic as well as treatment planning purposes. Presently, a large portion of the data is not optimally used towards medical decisions because information contained in the data is inaccessible through simple human inspection, or traditional computational methods. In the field of trauma medicine, where caregivers are frequently confronted with situations where …


A Peer-Tree Based Location Lookup Service In Mobile Wireless Networks, Jun Liu 2010 University of North Dakota

A Peer-Tree Based Location Lookup Service In Mobile Wireless Networks, Jun Liu

Computer Science Faculty Publications

We present a location look-up service for aiding location-based routing in wireless networks with mobile hosts. This location look up service is constructed based on a peer-tree indexing structure which represents the friendship relations among mobile hosts. The friendship is derived from the relations of sharing various-length common suffixes of host identifiers. A friendship relation determines the cooperation relation among mobile hosts. The Peer-Tree indexing structure provides a guideline for propagating location updates and queries in an organized manner. Each host periodically propagates its up-to-date location to a small number of its friends. Location queries are forwarded to and serviced …


Introduction To Selecting Subsets Of Traits For Quantitative Trait Loci Analysis, Tilman Achberger, James C. Fleet, David E. Salt, R. W. Doerge 2010 Kansas State University Libraries

Introduction To Selecting Subsets Of Traits For Quantitative Trait Loci Analysis, Tilman Achberger, James C. Fleet, David E. Salt, R. W. Doerge

Conference on Applied Statistics in Agriculture

Quantitative trait loci (QTL) mapping is a popular statistical method that is often used in agricultural applications to identify genomic regions associated with phenotypic traits of interest. In its most common form, a QTL analysis tests one phenotypic trait at a time using a variety of research hypotheses that depend on the application. When multiple traits are available, there are considerable benefits to analyzing subsets of biologically related traits in a multipletrait QTL mapping framework. Determining the most informative subset(s) of traits is the critical challenge that we address in this work. We present our approach, as well as simulations …


After Further Review: An Update On Modeling And Design Strategies For Agricultural Dose-Response Experiments, M. J. Frenzel, W. W. Stroup, E. T. Paparozzi 2010 Kansas State University Libraries

After Further Review: An Update On Modeling And Design Strategies For Agricultural Dose-Response Experiments, M. J. Frenzel, W. W. Stroup, E. T. Paparozzi

Conference on Applied Statistics in Agriculture

Research investigating dose-response relationships is common in agricultural science. This paper is an expansion on previous work by Guo, et al. (2006) motivated by plant nutrition research in horticulture. Plant response to level of nutrient applied is typically sigmoidal, i.e. no response at very low levels, observable response at mid-levels, point-of-diminishing returns and plateau at high levels. Plant scientists need accurate estimates of these response relationships for many reasons, including determining the lower threshold below which plants show deficiency symptoms and the point of diminishing returns, above which excessive doses are economically and environmentally costly. Guo et al. presented models …


A Non-Parametric Empirical Bayes Approach For Estimating Transcript Abundance In Un-Replicated Next-Generation Sequencing Data, Sanvesh Srivastava, R. W. Doerge 2010 Kansas State University Libraries

A Non-Parametric Empirical Bayes Approach For Estimating Transcript Abundance In Un-Replicated Next-Generation Sequencing Data, Sanvesh Srivastava, R. W. Doerge

Conference on Applied Statistics in Agriculture

Empirical Bayes approaches have been widely used to analyze data from high throughput sequencing devices. These approaches rely on borrowing information available for all the genes across samples to get better estimates of gene level expression. To date, transcript abundance in data from next generation sequencing (NGS) technologies has been estimated using parametric approaches for analyzing count data, namely – gamma-Poisson model, negative binomial model, and over-dispersed logistic model. One serious limitation of these approaches is they cannot be applied in absence of replication. The high cost of NGS technologies imposes a serious restriction on the number of biological replicates …


Nonlinear Regression Parameters As Outcomes: Simple Vs. Sophisticated Analyses, Reid D. Landes 2010 Kansas State University Libraries

Nonlinear Regression Parameters As Outcomes: Simple Vs. Sophisticated Analyses, Reid D. Landes

Conference on Applied Statistics in Agriculture

Sometimes a nonlinear regression parameter for an individual is the outcome of interest. But due to variability among individuals, the individuals’ regression parameters cannot be estimated with the same amount of precision. This problem of heterogeneous variance complicates the ultimate goal of estimating population-level regression parameters with two usual methods: (i) the simple arithmetic mean of individually estimated regression parameters and (ii) random coefficients regression (RCR). Weights are proposed for each method to account for the heterogeneity problem. The methods are illustrated with chick weights collected over time. Monte Carlo simulation allows comparison of statistical properties of the four estimators …


Approximate Bayesian Approaches For Reverse Engineering Biological Networks, Andrea Rau, Florence Jaffr´ezic, Jean-Louis Foulley, R. W. Doerge 2010 Kansas State University Libraries

Approximate Bayesian Approaches For Reverse Engineering Biological Networks, Andrea Rau, Florence Jaffr´Ezic, Jean-Louis Foulley, R. W. Doerge

Conference on Applied Statistics in Agriculture

Genes are known to interact with one another through proteins by regulating the rate at which gene transcription takes place. As such, identifying these gene-to-gene interactions is essential to improving our knowledge of how complex biological systems work. In recent years, a growing body of work has focused on methods for reverse-engineering these so-called gene regulatory networks from time-course gene expression data. However, reconstruction of these networks is often complicated by the large number of genes potentially involved in a given network and the limited number of time points and biological replicates typically measured. Bayesian methods are particularly well-suited for …
