Low-Mass X-ray Binaries and Globular Clusters in Early-Type Galaxies. II. Globular Cluster Candidates and their Mass-Metallicity Relation
Creators: name: Humphrey, Philip J
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present an astrometry and photometry catalogue of globular cluster (GC) candidates detected with HST WFPC2 in a sample of 19 early-type galaxies, appropriate for comparison to the low-mass X-ray binary (LMXB) populations observed with Chandra. In a companion paper, we present the Chandra data and investigate the relation between these populations. We demonstrate that, although there is little evidence of a colour-magnitude correlation for the GCs, after estimating mass and metallicity from the photometry, under the assumption of a single age simple stellar population, there is a significant positive correlation between mass and metallicity. We constrained [Z/H] = (-2.1+/-0.2)+(0.25+/-0.04)log M, with a 1-sigma intrinsic scatter of 0.62 dex in metallicity. If GCs are bimodal in metallicity this relation is consistent with recent suggestions of a mass-metallicity relation only for metal-poor clusters. Adopting a new technique to fit the GC luminosity function (GCLF) accounting for incompleteness and the Eddington bias, we compute the V-band local GC specific frequency (Sn) and specific luminosity (Sl) of each galaxy. We show that Sl is the more robust measure of the richness of a GC population where a significant fraction is undetected due to source detection incompleteness. We find that the absolute magnitude of the GCLF turnover exhibits intrinsic scatter from galaxy to galaxy of ~0.3mag (1-sigma), limiting its accuracy as a standard distance measure.

title: Test Suite for Multiobjective Optimization and Results Using Normal Boundary Intersection (NBI) in Design Explorer
Creators: name: Natarajan, Siva Kumar
Publisher: name: Utah State University
Year: 2003

description: Several methods have been developed to solve multiobjective optimization problems (MOP's). One of these, Normal Boundary Intersection (NBI), is a method developed by John Dennis and Indraneel Das. NBI is used at The Boeing Company as a tool to solve MOP's. This report presents a test suite of MOP's that I developed for Boeing during me internship in summer 2003.
The problems in the test suite were chosen to represent the different types of multiobjective optimization problems that could arise in practice and the complexities involved in solving them. These problems range from those that have nice convex Pareto surfaces to those that have complex disconnected Pareto surfaces. We study whether or not NBI can solve these problems, and the difficulties that arise. The suite also includes real world examples, in particular a truss design problem.
title: The Robustness of Factor Analyses When the Data Does Not Conform to Standard Parametric Requirements
Creators: name: Peng, Haisong
Publisher: name: Utah State University
Year: 2004

description: Objective: To access the robustness of factor analyses when the data does not conform to standard parametric requirements.
Methods: Data were simulated in package R. Maximum likelihood was used to fit and assess the factor models. Chi-square statistics were obtained to test hypotheses about the correct number of factors in simulated settings where the true number of factors was known. The number of true factors varied between 1 and 3; the number of observed variables was either 6 (for 1 factor) or 3 per factor for 2 or more factors.
Results: With standard normal factor populations, and normal errors added to each observed variable, the standard MLE statistics and chi-squared tests gave expected results, in terms of false rejection (Type I Error) rates, with sample size set at 100, and either 3 or 6 observed variables per factor. For normal factors, but non-normal noise added to observed variables, the robustness of the chi-square statistics varied from excellent to modest, depending on the extent to which the noise distribution varied from normal.
Conclusions: When the sample size n=100, the robustness of the chi-square statistics for the normal data added with gamma or Poisson noise and the discrete uniform data added with discrete uniform noise are excellent, and those for the normal data with exponential or lognormal noise are pretty remarkable, too. However, when the sample size decreased to 25, the robustness for all the data become very modest; Among them, the robustness for the normal data added with gamma and Poisson are better than the others, and that for the discrete uniform data with discrete uniform case is next to them, the chi-square statistics for the normal data added with exponential and lognormal have the modest robustness.

title: Special Classification Models for Lichens in the Pacific Northwest
Creators: name: Ardito, Janeen
Publisher: name: Utah State University
Year: 2005

description: A common problem in ecological studies is that of determining where to look for rare species. This paper shows how statistical models, such as classification trees, may be used to assist in the design of probability-based surveys for rare species using information on more abundant species that are associated with the rare species. This model assisted approach to survey design involves first building models for the more abundant species. The models are then used to determine stratifications for the rare species that are associated with the more abundant species. The goal of this approach is to increase the number of detections of the rare species. This project extends the work of Edwards et al. (2005) by including site level characteristics such as age of dominant conifer and size class of the largest trees at the site, and by modeling additional species.
title: Examining the Validity of the Spring 2007 Math 1050 Common Final
Creators: name: Brock, Angela K.
Publisher: name: Utah State University
Year: 2008

description: I began this study wanting to know more about the Math 1050 Common Final. I've heard so many negative things about the class from students, I wondered if the common final, which has so much influence on students' grades, is actually valid. A measurement is valid to the degree that it is both reliable and relevant, so I needed to address both relevance and reliability. To do this, I began by finding a reliability coefficient for the multiple choice section. I then analyzed each item with respect to difficulty, discrimination and efficiency. To determine content and learning level relevance, I used the Measurement Analysis Coding Form.
To begin, I collected the final exams from one Spring 2007 Math 1050 section. The final consists of 20 Multiple Choice items worth 7 pts each and 5 free response items worth 12 pts each. I then recorded the scores of each multiple choice question and, using these scores, I calculated a reliability coefficient. When doing this, I calculated me as 1 pt each so as not to artificially inflate the variance.
Photodesorption of acetonitrile CH3CN in UV-irradiated regions of the Interstellar Medium: an experimental evidence

description: Pure acetonitrile (CH3CN) and mixed CO:CH3CN and H2O:CH3CN ices have been irradiated at 15K with Vacuum UltraViolet (VUV) photons in the 7-13.6 eV range using synchrotron radiation. VUV photodesorption yields of CH3CN and of photo-products have been derived as a function of the incident photon energy. The coadsorption of CH3CN with CO and H2O molecules, which are expected to be among the main constituents of interstellar ices, is found to have no significant influence on the VUV photodesorption spectra of CH3CN, CHCN, HCN, CN and CH3. Contrary to what has generally been evidenced for most of the condensed molecules, these findings point toward a desorption process for which the CH3CN molecule that absorbs the VUV photon is the one desorbing. It can be ejected in the gas phase as intact CH3CN or in the form of its photo-dissociation fragments. Astrophysical VUV photodesorption yields, applicable to different locations, are derived and can be incorporated into astrochemical modeling. They vary from 0.67(+/-0.33).10^{-5} to 2.0(+/-1.0).10^{-5} molecule/photon for CH3CN depending on the region considered, which is high compared to other organic molecules such as methanol. These results could explain the multiple detections of gas phase CH3CN in different regions of the interstellar medium and are well-correlated to astrophysical observations of the Horsehead nebula and of protoplanetary disks (such as TW Hya and HD 163296).

title: Evaluating the Computational Efficiency of XFBAT and FBAT for Family Based Studies
Creators: name: Ouyang, Yanwei
Publisher: name: Utah State University
Year: 2006

description: Family-based study designs are often employed when investigating the genetic causes of complex disease. While the transmission disequilibrium test (TDT) and its extensions were developed to use family data for assessing linkage between a known genetic marker and a disease-causing gene, the so-called FBAT approach proposed by Rabinowitz and Laird (2000) effectively subsumes these family-based procedures as special cases. FBAT is fully conditional, but its implementation in the freely available FBAT software package uses a large-sample distributional approximation to compute p-values. The exact distribution for FBAT can be enumerated, but doing so explicitly is computationally intensive, particularly for relatively larger sample sizes. Schneiter et al. (2005) proposed an efficient algorithm for computing the exact p-value, but the computational performance of this procedure has not been systematically evaluated. In this report, we carry out a simulation study to determine the relative computational efficiency of large-sample FBAT and exact FBAT (XFBAT). Characteristic of all exact significance tests in statistical practice, XFBAT is significantly more computationally burdensome, and its efficiency decreases exponentially for larger sample sizes. In addition, XFBAT is more computationally intensive under the additive inheritance model, as opposed to either the dominant or recessive models.

title: A Method for Finding Standard Error Estimates for RMA Expression Levels Using Bootstrap
Creators: name: Nicholas, Gabriel
Publisher: name: Utah State University
Year: 2007

description: Oligonucleotide arrays are used in many applications. Affymetrix GeneChip arrays are widely used. Before researchers can use the information from these arrays, the raw data must be transformed and summarized into a more meaningful and usable form. One of the more popular methods for doing so is RMA (Robust Multi-array Analysis).
A problem with RMA is that the end result (estimated gene expression levels) is based on a fairly complicated process that is unusual. Specifically, there is no closed-form estimate of standard errors for the estimated gene expression levels. The current recommendation is to use a naive estimate for the SE that is based on a simple ANOVA model. This results in an estimated SE that is the same for all arrays even when there is reason to believe they should be different.
This paper investigates a computationally efficient implementation of bootstrapping as a way to get a valid estimate of the standard errors of RMA expression levels. Oligonucleotide arrays contain a lot of data, and processing that data already carries a significant cost in computation. Bootstrapping compounds this cost. Consequently efforts have been made to reduce the required number of resamples while still getting a reasonable estimate of the standard error. The accompanying R function is however flexible enough to do as many resamples as are required; the tradeoff is that more resamples mean more computation time will be needed.

Investigation of the degree of local structural similarity between the parent-liquid and children-crystal states for a model soft matter system

description: We investigate the degree of local structural similarity between the parent-liquid and children-crystal states for a model soft-matter system of particles interacting through the harmonic-repulsive pair potential. At different pressures, this simple system crystallizes into several significantly different crystal structures. Therefore, the model is well suited for addressing the question under consideration. In our studies, we carefully analyze the developments of the pair and triple correlation functions for the parent-liquid as the pressure increases. In particular, these considerations allow us to address the similarities in the orientational orderings of the corresponding liquid and solid phases. It is demonstrated that the similarities in the orientational ordering between the two states extend beyond the first and second neighbors. Currently, it is widely accepted that orientational ordering is important for understanding the behaviors of liquids, supercooled liquids, and the development of detailed theories of the crystalization process. Our results suggest that, up to a certain degree, it might be possible to predict the structures of the children-solids from studies of the parent-liquids. Our results raise anew a general question of how much insight into the properties of the liquid-state can be gained from drawing a parallel with the solid-state.

Identification of object composition with Magnetic Inductive Tomography

Year: 2021
Subjects: subject: Applied Physics (physics.app-ph)

description: The inductive response of an object to an oscillating magnetic field reveals information about its electrical conductivity and magnetic permeability. Here we introduce a technique that uses measurements of the angular, frequency and spatial dependence of the inductive signal to determine object composition. Identification is performed by referencing an object's inductive response to that of materials with mutually exclusive properties such as copper (high electric conductivity, negligible magnetic permeability) and ferrite (negligible electric conductivity, high magnetic permeability). The technique uses a sensor with anisotropic sensitivity to discriminate between the different characters of the eddy current and magnetisation driven object responses. Experimental validation of the method is performed through Magnetic Induction Tomography measurement with a radio-frequency atomic magnetometer. Possible applications of the technique in security screening devices are discussed.

description: It is no doubt that the most important contributing cause of global efficiency of coal fired thermal systems is combustion efficiency. In this study, the relationship between the flame image obtained by a CCD camera and the excess air coefficient (λ) has been modelled. The model has been obtained with a three-stage approach: 1) Data collection and synchronization: Obtaining the flame images by means of a CCD camera mounted on a 10 cm diameter observation port, λ data has been coordinately measured and recorded by the flue gas analyzer. 2) Feature extraction: Gridding the flame image, it is divided into small pieces. The uniformity of each piece to the optimal flame image has been calculated by means of modelling with single and multivariable Gaussian, calculating of color probabilities and Gauss mixture approach. 3) Matching and testing: A multilayer artificial neural network (ANN) has been used for the matching of feature-λ.

The spectra, mid-IR, and X-ray properties indicate the bolometric luminosity is dominated by star formation at a rate of >1000M_sun per yr. Multiple, spatially separated components are visible in the Ly-Alpha line with an observed velocity difference of up to 380 km/sec and the object morphology indicates a merger. The best fit spectral energy distribution and spectral line indicators suggest the object is 2-8 Myr old and contains >10^10 M_sun of stellar mass. This object is a likely progenitor for the massive early type systems seen at z~2.

Creators: name: Oana, Joan Leilani
Publisher: name: Utah State University
Year: 1991

description: The purpose of this report is to investigate the behavior of a nonreactive contaminant in a perfectly stratified aquifer under uniform, steady-state flow. The design and the implementation of a solute transport model which characterizes the heterogeneities of the aquifer properties in a stochastic framework is reviewed. The model closely examines the advection and dispersion of the plume. The advection is the process by which the plume is transported in the aquifer by the bulk average motion of the groundwater whereas the dispersion refers to the spreading of the plume about its mean displacement position. The relationship between the fractally distributed hydraulic conductivity and the extent of spreading is the focus of investigation.

description: We discuss the stability of a homogeneous two-dimensional Bose gas at finite temperature against formation of isolated vortices. We consider a patch of several healing lengths in size and compute its free energy using the Euclidean formalism. Since we deal with an open system, which is able to exchange particles and angular momentum with the rest of the condensate, we use the symmetry-breaking (as opposed to the particle number conserving) formalism, and include configurations with all values of angular momenta in the partition function. At finite temperature, there appear sphaleron configurations associated to isolated vortices. The contribution from these configurations to the free energy is computed in the dilute gas approximation. We show that the Euclidean action of linearized perturbations of a vortex is not positive definite. As a consequence the free energy of the 2D Bose gas acquires an imaginary part. This signals the instability of the gas. This instability may be identified with the Berezinskii, Kosterlitz and Thouless (BKT) transition.

Creators: name: Allen, Cassidy P.

Year: 2008

description: The Cache County Memory Study (CCMS) is a longitudinal study of the elderly in Cache County, Utah, that was initiated over twelve years ago to explore the role of APOE genotype and other environmental factors in dementia risk and cognitive function. Collaboration between the CCMS and investigators with the Utah Population Database (UPDB) at the University of Utah has revealed a significant number of sibships among the original 5,092 CCMS participants, along with complex pedigrees that include additional thousands of ancestors and relatives not enrolled in the Cache Study. Information about these families and pedigrees raises the potential for studies of the genetic epidemiology of age-related traits. Until biological samples from the Cache cohort can be leveraged for genetic association studies of cognition, a useful first step is to explore the heritability of cognition and cognitive decline (i.e., the degree to which these quantitative traits are inherited).
The objectives of this project are to:
1. Compare and contrast results from previous studies of the heritability of cognition and cognitive change among the elderly.
2. Use software tools to compute heritability measures with respect to cognitive function for the nuclear families within the CCMS. Additionally account for potential confounding factors - such as APOE genotype and age - and explain their effects.
3. Identify potential methods for more complex analyses with the CCMS data that could include information about complex pedigrees and repeated cognitive measures.
Photon-axion mixing in thermal emission of isolated neutron stars

description: Thermally emitting neutron stars represent a promising environment for probing the properties of axion-like particles. Due to the strong magnetic fields of these sources, surface photons may partially convert into such particles in the large magnetospheric region surrounding the stars, which will result in distinctive signatures in their spectra. However, the interaction depends on the polarization state of the radiation and is rather weak due to the low experimentally allowed values of the coupling constant $g_{γa}$. In this work, we compute the degree of photon-axion transition in the case of 100% O-mode polarization and spectral energy distribution of an isotropic blackbody with uniform surface temperature. The stellar magnetic field is assumed to be dipolar. We show that with the maximum effect reached for the magnetic fields $\sim10^{13}$ - $10^{14}$ G (typical for X-ray dim isolated neutron stars) and $g_{γa} = 2 \times 10^{-11}$ GeV$^{-1}$, the optical flux is reduced by 30 - 40%, while the high-energy part of the spectrum is not affected. The low-energy decrease exceeds 5% at $g_{γa} \geq 2 \times 10^{-12}$ GeV$^{-1}$ and $m_a \leq 2\times 10^{-6}$ eV, which is below the present experimental and astrophysical limits on axion parameters. To obtain the actual observational constraints, rigorous treatment of the radiative surface layers is required.

Kinetic spectroscopic studies of alkyl, alkylperoxy and acetyl radicals
Creators: name: Adachi, Hiroyuki
Publisher: name: University of British Columbia
Year: 2010

description: The main objectives of this investigation are (i) the characterization of the absorption spectra of four radicals: the ethyl, methylperoxy, ethylperoxy and acetyl radicals, and (ii) the measurement of the rate constants of some of their characteristic rapid reactions. The spectral and kinetic measurements reported in this dissertation were made possible by an advance in experimental technique that increased the sensitivity of measurement of absorbance by an order of magnitude. This increase was achieved by a combination of (i) an increase in the intensity of the analytical light source by the application of a square wave voltage pulse, and (ii) the use of a dual beam optical system with balanced photomultipliers. The parameters that characterize the absorption spectra of the four principal radicals (and related species) are listed in Table-1. The rate constants measured for reactions of the four principal radicals (and related species) are listed in Table-2. [tables not included]

description: Des défaillances dans la communication au sein des équipes surviennent de manière chronique au bloc opératoire et peuvent entraîner des conséquences graves. Nous avons réalisé un travail de recherche clinique sur la qualité de la communication dans un bloc d’endoscopie digestive, au moyen d’enregistrements des conversations. Nous rapportons les résultats de cette étude prospective, réalisée avant et après le retour des résultats à l’équipe. Faisant appel à la notion de réflexivité en équipe, nous montrons que la réalisation d’enregistrements audio au bloc permet l’amélioration des processus, notamment pour la réalisation de la check-list sécurité du patient en endoscopie digestive, et des résultats intermédiaires, comme l’amélioration de la qualité de la communication ou la diminution de certaines distractions et interruptions de tâche. En revanche, du fait de la rareté des complications en endoscopie digestive, nous n’avons pu démontrer une diminution du nombre d’événements indésirables. Nous envisageons également les problèmes techniques et éthiques soulevés par une telle démarche.

title: Mixtures of Truncated Normal Data Assimilation Models for Parameter Estimation and Prediction in Hydrological Systems
Creators: name: Flake, Darl D.
Publisher: name: Utah State University
Year: 2008

description: Physical models in the hydrological sciences are often calibrated using methods that do not formally quantify uncertainty in the model parameters. Additionally, many competing hydrological models exist and are used to model the same processes. Considering existing mechanistic models of rainfall-run off in a statistical context can assist hydrologists in understanding the true physical process taking place. This paper introduces a data assimilation mixture model of runoff that yields statistical estimates of hydrological mode l parameters and predictions. This statistical model incorporates two commonly used hydrological models, each with strengths and weaknesses. The mixture framework allows comparisons between models as well as combines the strengths of both. Results from three implementations of the mixture model are summarized and additional generalizations of the models are suggested.
Some experiments on headed stud connections for precast concrete panels under monotonic and cyclic shear loading
Creators: name: Bischof, Max
Publisher: name: University of British Columbia
Year: 2010

description: The research on headed stud connections described in this thesis forms a part of a larger program with the objective of predicting the behaviour of precast concrete panel buildings under earthquake loads. The first objective of this research is to produce experimentally a concrete failure of the connection and to compare the actual failure load to the one predicted by the PCI design handbook. The tests show that the PCI shear-tension interaction equation for single headed studs can be used for the prediction of a concrete failure for a connection of the type tested. This method yields conservative results if a special equilibrium model for the determination of the stud tension force is used, and the bearing capacity of the structural steel angle on the concrete is neglected. The second objective of this research is to determine the bearing capacity of a reversed angle connection. Experiments show that this bearing capacity is equivalent to a force resulting from a stress equal to the concrete strength uniformly distributed over the concrete area enclosed by the structural steel angle 2" x2". Furthermore, the location of this force can be assumed in the center of gravity of the structural steel angle shape, regardless of whether or not there is an endplate present.
title: Hands-on Activities and Activities Involving Technology to Help Students Construct Concepts and Gain a Deeper Understanding and Appreciation for Mathematical Concepts Based on the Utah Core Curriculum for Algebra II

Year: 2008

description: Research shows there are several methods that expand students' understanding, appreciation for, and interest in mathematics by following teaching strategies. These strategies include incorporating hands-on activities, technology, discovery learning, cooperative learning, and having activities be applicable to real world contexts. This project focuses specifically on activities based on objectives from the Utah State Core for Algebra II that incorporate such strategies in five units: (I) absolute value, (2) exponential growth /decay and logarithms, (3) trigonometric functions, (4) probability, permutations and combinations, and (5) statistics.

Il interroge également les conditions de diffusion de ce type de dispositif qui serait certainement souhaitable au regard des besoins.
Probing Metal-Molecule Contact at the Atomic Scale via Conductance Jump

description: Understanding the formation of metal-molecule contact at the microscopic level is the key towards controlling and manipulating atomic scale devices. Employing two isomers of bipyridine, $4, 4^\prime$ bipyridine and $2, 2^\prime$ bipyridine between gold electrodes, here, we investigate the formation of metal-molecule bond by studying charge transport through single molecular junctions using a mechanically controlled break junction technique at room temperature. While both molecules form molecular junctions during the breaking process, closing traces show the formation of molecular junctions unambiguously for $4, 4^\prime$ bipyridine via a conductance jump from the tunneling regime, referred as `jump to molecular contact', being absent for $2, 2^\prime$ bipyridine. Through statistical analysis of the data, along with, molecular dynamics and first-principles calculations, we establish that contact formation is strongly connected with the molecular structure of the electrodes as well as how the junction is broken during breaking process, providing important insights for using a single-molecule in an electronic device.

description: Part-of-speech (POS) tagging is a fundamental component for performing natural language tasks such as parsing, information extraction, and question answering. When POS taggers are trained in one domain and applied in significantly different domains, their performance can degrade dramatically. We present a methodology for rapid adaptation of POS taggers to new domains. Our technique is unsupervised in that a manually annotated corpus for the new domain is not necessary. We use suffix information gathered from large amounts of raw text as well as orthographic information to increase the lexical coverage. We present an experiment in the Biological domain where our POS tagger achieves results comparable to POS taggers specifically trained to this domain.
