An isogeometric analysis for elliptic homogenization problems

description: A novel and efficient approach which is based on the framework of isogeometric analysis for elliptic homogenization problems is proposed. These problems possess highly oscillating coefficients leading to extremely high computational expenses while using traditional finite element methods. The isogeometric analysis heterogeneous multiscale method (IGA-HMM) investigated in this paper is regarded as an alternative approach to the standard Finite Element Heterogeneous Multiscale Method (FE-HMM) which is currently an effective framework to solve these problems. The method utilizes non-uniform rational B-splines (NURBS) in both macro and micro levels instead of standard Lagrange basis. Beside the ability to describe exactly the geometry, it tremendously facilitates high-order macroscopic/microscopic discretizations thanks to the flexibility of refinement and degree elevation with an arbitrary continuity level provided by NURBS basis functions. A priori error estimates of the discretization error coming from macro and micro meshes and optimal micro refinement strategies for macro/micro NURBS basis functions of arbitrary orders are derived. Numerical results show the excellent performance of the proposed method.
The cognitive and social world of schizophrenics as perceived by health care professionals and experienced by schizophrenics themselves: Autoethnography and interviews
Creators: name: Paz, Pauline Bukantz
Publisher: name: University of Nevada, Las Vegas
Year: 1993

description: This ethnographic research involved an autoethnography, and interviews of health care professionals and schizophrenic patients. The autoethnography detailed the researcher's personal experiences with schizophrenia, which were compared to other autoethnographies. Three psychiatrists, a therapist, psychiatric hospital unit manager, social worker, nurse, and psychiatric nurse's aide were interviewed, as were six schizophrenic patients, including three from the same family. The interviews were compared, and findings were correlated to the literature. Schizophrenics are individuals, not homogeneous in personality or life experience; schizophrenia is not uniform for all. Patients were dependent upon their doctors and support network. Schizophrenic family communication dynamics were examined. There was no support for the presence of a schizophrenic language. Bizarre behavior was not noted. Flatness of affect and repetitiousness were observed. A paucity of abstract ideas was seen. Divergence in philosophy and role of individual health care professionals was noted. Schizophrenia is a debilitating, presently incurable, genetic disease with diverse, but similar features that affects all aspects of life, but particularly affects communication with self and others.

Bayesian nonparametric analysis of reversible Markov chains

description: We introduce a three-parameter random walk with reinforcement, called the $(θ,α,β)$ scheme, which generalizes the linearly edge reinforced random walk to uncountable spaces. The parameter $β$ smoothly tunes the $(θ,α,β)$ scheme between this edge reinforced random walk and the classical exchangeable two-parameter Hoppe urn scheme, while the parameters $α$ and $θ$ modulate how many states are typically visited. Resorting to de Finetti's theorem for Markov chains, we use the $(θ,α,β)$ scheme to define a nonparametric prior for Bayesian analysis of reversible Markov chains. The prior is applied in Bayesian nonparametric inference for species sampling problems with data generated from a reversible Markov chain with an unknown transition kernel. As a real example, we analyze data from molecular dynamics simulations of protein folding.

Publisher: name: Utah State University
Year: 2019

description: In many classes, students are faced with the daunting task of remembering a lot of terms or structures in a relatively short period of time. Though there is much to memorize, students may not be aware of the many mnemonic mechanisms that can help them make quick and lasting memories. This article describes three such mechanisms: word associations, visual images, and stories. Examples of how these mechanisms can be applied, either individually or in combination, are provided in the context of teaching human anatomy. Whether used by teacher or student, these mechanisms can be incorporated into a class, providing fun and effective ways to both teach and learn.

description: Significant progress has been made in recent years in constraining nuclear symmetry energy at and below the saturation density of nuclear matter using data from both terrestrial nuclear experiments and astrophysical observations. However, many interesting questions remain to be studied especially at supra-saturation densities. In this lecture note, after a brief summary of the currently available constraints on nuclear symmetry energy near the saturation density we first discuss the relationship between the symmetry energy and the isopin and momentum dependence of the single-nucleon potential in isospin-asymmetric nuclear medium. We then discuss several open issues regarding effects of the tensor force induced neutron-proton short-range correlation (SRC) on nuclear symmetry energy. Finally, as an example of the impacts of nuclear symmetry energy on properties of neutron stars and gravitational waves, we illustrate effects of the high-density symmetry energy on the tidal polarizability of neutron stars in coalescing binaries.

title: Apathy and Concern Over the Future Habitability of Earth: An Introductory College Assignment of Forecasting CO2 in the Earth’s Atmosphere
Creators: name: Burger, Benjamin J
Publisher: name: Utah State University
Year: 2019

description: Non-science, first year regional undergraduate students from rural Utah communities participated in an online introductory geology course and were asked to forecast the rise of CO2 in the Earth’s atmosphere. The majority of students predicted catastrophic rise to 5,000-ppm sometime over the next 3,100 years, resulting in an atmosphere nearly uninhabitable to human life. However, the level of concern the students exhibited in their answers was not directly proportional with their timing in their forecasted rise of CO2. This study showcases the importance of presenting students with actual data and using data to develop student forecasted models. It also illustrates the challenge in environmental science with the cognitive issue of temporal discounting, in which the consequences of these future predictions tend to be viewed apathetically due to the long durations in which they play out.

Year: 2019

description: This article is a case study of how student data can guide instructors in course redesign. A significant percentage of students enrolled in an American Civilization course did not successfully complete the course. An examination of ACT scores, GPAs, grades in math and English composition, reading tests, and assignment completion rates indicated that two key obstacles to student success were a lack of student engagement and a disparity between student reading capabilities and the required instructional materials. Following a change in the topical focus of the course, the addition of active learning projects, and supplemental aids to the textbook, course completion increased.

description: Consider a pseudogroup on (C,0) generated by two local diffeomorphisms having analytic conjugacy classes a priori fixed in Diff(C,0). We show that a generic pseudogroup as above is such that every point has (possibly trivial) cyclic stabilizer. It also follows that these generic groups possess infinitely many hyperbolic orbits. This result possesses several applications to the topology of leaves of foliations and we shall explicitly describe the case of nilpotent foliations associated to Arnold's singularities of type A^{2n+1}.

description: Sea surface height anomalies observed by satellites in 1993--2012 are combined with simulation and observations by surface drifters and Argo floats to study water flow pattern in the Near Strait (NS) connected the Pacific Ocean with the Bering Sea. Daily Lagrangian latitudinal maps, computed with the AVISO surface velocity field, and calculation of the transport across the strait show that the flow through the NS is highly variable and controlled by mesoscale and submesoscale eddies in the area. On the seasonal scale, the flux through the western part of the NR is negatively correlated with the flux through its eastern part ($r=-0.93$). On the interannual time scale, a significant positive correlation ($r=0.72$) is diagnosed between the NS transport and the wind stress in winter. Increased southward component of the wind stress decreases the northward water transport through the strait. Positive wind stress curl over the strait area in winter--spring generates the cyclonic circulation and thereby enhances the southward flow in the western part ($r=-0.68$) and northward flow in the eastern part ($r=0.61$) of the NR. In fall, the water transport in different parts of the NS is determined by the strength of the anticyclonic mesoscale eddy located in the Alaskan Stream area.

description: This paper deals with the problem of stabilizing an unstable system through networked control over the wireless medium. In such a situation a remote sensor communicates the measurements to the system controller through a noisy channel. In particular, in the AWGN scenario, we show that protograph-based LDPC convolutional codes achieve anytime reliability and we also derive a lower bound to the signal-to-noise ratio required to stabilize the system. Moreover, on the Rayleigh-fading channel, we show by simulations that resorting to multiple sensors allows to achieve a diversity gain.

description: We investigate the distribution of work performed on a Brownian particle in a time-dependent asymmetric potential well. The potential has a harmonic component with time-dependent force constant and a time-independent logarithmic barrier at the origin. For arbitrary driving protocol, the problem of solving the Fokker-Planck equation for the joint probability density of work and particle position is reduced to the solution of the Riccati differential equation. For a particular choice of the driving protocol, an exact solution of the Riccati equation is presented. Asymptotic analysis of the resulting expression yields the tail behavior of the work distribution for small and large work values. In the limit of vanishing logarithmic barrier, the work distribution for the breathing parabola model is obtained.

description: We investigate the regularity of linear stochastic parabolic equations with zero Dirichlet boundary condition on bounded Lipschitz domains $O \subset R^d$ with both theoretical and numerical purpose. We use N.V. Krylov's framework of stochastic parabolic weighted Sobolev spaces $\mathfrak{H}^{γ,q}_{p,θ}(O;T)$. The summability parameters p and q in space and time may differ. Existence and uniqueness of solutions in these spaces is established and the Hölder regularity in time is analysed. Moreover, we prove a general embedding of weighted Lp(O)-Sobolev spaces into the scale of Besov spaces $B^α_{τ,τ}(O), 1/τ=α/d+1/p, α> 0$. This leads to a Hölder-Besov regularity result for the solution process. The regularity in this Besov scale determines the order of convergence that can be achieved by certain nonlinear approximation schemes.

Optimal discriminating designs for several competing regression models

description: The problem of constructing optimal discriminating designs for a class of regression models is considered. We investigate a version of the $T_p$-optimality criterion as introduced by Atkinson and Fedorov [Biometrika 62 (1975a) 289-303]. The numerical construction of optimal designs is very hard and challenging, if the number of pairwise comparisons is larger than 2. It is demonstrated that optimal designs with respect to this type of criteria can be obtained by solving (nonlinear) vector-valued approximation problems. We use a characterization of the best approximations to develop an efficient algorithm for the determination of the optimal discriminating designs. The new procedure is compared with the currently available methods in several numerical examples, and we demonstrate that the new method can find optimal discriminating designs in situations where the currently available procedures fail.

description: Hierarchical autocorrelation in the error term of linear models arises when sampling units are related to each other according to a tree. The residual covariance is parametrized using the tree-distance between sampling units. When observations are modeled using an Ornstein-Uhlenbeck (OU) process along the tree, the autocorrelation between two tips decreases exponentially with their tree distance. These models are most often applied in evolutionary biology, when tips represent biological species and the OU process parameters represent the strength and direction of natural selection. For these models, we show that the mean is not microergodic: no estimator can ever be consistent for this parameter and provide a lower bound for the variance of its MLE. For covariance parameters, we give a general sufficient condition ensuring microergodicity. This condition suggests that some parameters may not be estimated at the same rate as others. We show that, indeed, maximum likelihood estimators of the autocorrelation parameter converge at a slower rate than that of generally microergodic parameters. We showed this theoretically in a symmetric tree asymptotic framework and through simulations on a large real tree comprising 4507 mammal species.

Public perceptions of buildings constructed of recycled materials
Creators: name: Strauss, Laura Michele
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: The study presented herewith investigated public perceptions of buildings constructed of recycled materials. The three groups surveyed in the area of Las Vegas were the general public, Clark County School District construction management employees, and local architectural firms. Eight attributes of recycled building products were addressed in the survey, namely their availability, aesthetics, cost, maintenance, quality, health risks, life expectancy, and safety. Data collected from returned questionnaires were analyzed using the Statistical Package for the Social Sciences software package. Results indicate that: (1) the general public is largely unaware of the use of these products; (2) people in all three groups who are by and large cognizant of their existence, perceive them as aesthetically acceptable, and consider them as having the same cost, maintenance, quality, health risks, life expectancy, and safety as standard building products; (3) the general public's perception of the impact of their use on the environment is positive and prefers an increase in their use; (4) The Clark County School District construction management employees, even though aware of their market availability, have not requested their use in CCSD buildings; and (5) architects are mostly aware of their availability yet generally have neither recommended nor received any requests from their clients for the use of these products. Analyses of these results, conclusions, and recommendations are also presented in this study.

description: The Insomnia Severity Index (ISI) is a brief seven-item measure of insomnia that has been validated among multiple civilian populations but not in the U.S. active-duty military population. The current study examined and evaluated the psychometric properties of the ISI across multiple samples of active-duty service members. Methods: A secondary data analysis of N = 4672 active-duty service members was conducted with data from the South Texas Research Organization Network Guiding Studies on Trauma and Resilience (STONG STAR). The reliability, factor validity, construct validity, sensitivity, and invariance across gender, deployment experience, trauma symptoms, and clinical diagnosis were evaluated. Results: The ISI had strong reliability (Omega-T = 0.95) and support for criterion, convergent, and discriminant validity. An alternative six-item two-factor model was validated across multiple samples representing clinical and non-clinical samples. The ISI had strong scalar invariance across gender (∆ x² = 19.538 (16), p > 0.05), combat deployment experience (∆ x² = 24.187 (16), p > 0.05), and endorsed trauma symptoms (∆ x² = 22.201 (16), p > 0.05). ROC analysis supported the measure's discriminate ability (AUC = 0.85). Conclusion: The study contributes the first validation of the ISI among active-duty service members. The findings support the ISI use as an insomnia screening instrument among the military population and inclusion in the VA/DoD clinical practice guidelines.

We apply this method to a sample of 23 radio-loud narrow-line Seyfert 1 (RL-NLS1) galaxies, using data from WISE (Wide-field Infrared Survey Explorer), SDSS (Sloan Digital Sky Survey) and GALEX. Our black hole mass estimates are at least a factor $\sim$6 above previous results based on single epoch virial methods, while the Eddington ratios are correspondingly lower. Hence, the black hole masses of RL-NLS1 galaxies are typically above $10^8 M_{\sun}$, in agreement with the typical black hole mass of blazars.

Statistical evaluation of motorist and pedestrian behavior at signalized intersections in Las Vegas
Creators: name: Subramani, Sivashankar
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: This study examines the effect of a law enforcement program implemented to check illegal and unsafe motorist and pedestrian behavior. A case study involving eight selected intersections in Las Vegas (four control and four treatment) was carried out over a period of seven months in conjunction with the pedestrian law enforcement program conducted during March and April of 1996. Pedestrian and motorist behaviors were video taped in 120 minute segments. The tapes were then reviewed to count vehicle violations, pedestrian violations, conflicts, total vehicles and total pedestrians. Violations and conflict rates for pre and during enforcement, and pre and post enforcement phases were compared using the Wilcoxon signed rank test - matched pairs. Regression analyses were then conducted to determine the effect of intersection design characteristics on violations and conflicts; The results from the nonparametric statistical tests suggest that the law enforcement program did not have any long term impact on reducing pedestrian violations, vehicle violations and conflicts. The results from the regression analysis identified "pedestrian volume" as a significantly consistent explanatory variable for the dependent variable "pedestrian violations". Likewise "vehicle violations" and "with signal outside crosswalk violations" showed up as significantly consistent explanatory variables for the dependent variable "conflicts".

description: Using a network approach, we investigate the determinants of intra-EU migration flows between all 28 EU member states in the years 2001, 2005, 2008 and 2013. Our descriptive analysis of the networks of intra-EU migration flows shows that the EU migration space is dominated by two core destination countries (Germany and United Kingdom). The results of our cross-sectional exponential random graph models (ERGM) reveal that the status of Germany and the United Kingdom (UK) as core destination countries remains a robust characteristic of the network of intra-EU migration flows over time, even when controlling for GDP, unemployment rates or shared geographical borders between destination and source countries. Furthermore, our results point to the differentiated effects of national economic performance on outgoing and ingoing flows: GDP per capita mainly affects intra-EU inflows, while unemployment rates tend to influence outmigration. Lastly, regulatory linkages – measured with the accession to the EU of source countries and the opening of the labour market of destination countries – exert a moderate effect on intra-EU migration flows when taking into account the national economic performances of source and destination countries, the core status of Germany and the United Kingdom, and the shared borders between destination and source countries.

Breaking up is hard to do: The dissolution of romantic relationships
Creators: name: Sheehan, Megan Ann
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: This investigation of the dissolution of dating relationships was based on the surveys of 78 subjects. Subjects who reported being the rejectee experienced more distress than subjects who reported being the initiators or subjects who reported mutual breakups. As the length of the relationship increased, distress over the breakup increased. One component of the study examined the transformation of romantic relationships to cross-sex friendships. Nearly half of the subjects reported that they were either friends, close friends, or best friends with their former partner. The two variables which showed a significant correlation with friendship after dating were friendship prior to dating and the use of indirect communication strategies to bring about the breakup. There were substantial implications for future research with regard to relationship dissolution and friendship after the breakup.

Friedrich Sieburg, a twentieth-century German francophile
Creators: name: Sommer, Frederick Matthew
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: Friedrich Sieburg achieved renown as a German literary critic in the years following World War II. His career in journalism and diplomacy prior to 1945, largely ignored in the 1950s and 1960s, has come under a new scrutiny since 1980. The connection between Sieburg's writings, many of which dealt with France, and his work with the German Foreign Office in wartime Paris has been a particular object of this scrutiny. The study Friedrich Sieburg. A Twentieth-Century German Francophile builds on the work of Joachim Fest, Margot Taureck and others, and argues that Sieburg was a romantic nationalist who became a National Socialist. He constructed a theory, from elements in the German literary tradition, which posited French form in opposition to German mass. This theory makes intelligible his praise of the German 1933 as a national awakening and as the workings of a mythic destiny. Journalism and diplomacy served Sieburg's historic role as national publicist. After 1945, Sieburg was generally silent about the Hitler regime; his was a common response in a nation unwilling to assess its past. Attached to this study is a translation of the greater part of the memoir of Paris, Our Most Beautiful Years, which Sieburg published in 1950.
Feminist theory: Gender, race and recidivism
Creators: name: Shuck, Amie M
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: Feminists and women of color have criticized criminological theories for being developed by white middle-class men to explain white male delinquency, and thus, are limited in their understanding of crime and deviance within a gender or racial context. The purpose of this study is to use a series of logistic regression models to evaluate this assertion regarding criminological 'theories' of recidivism. The results indicate that there are substantive differences in statistically significant coefficients, models explanatory power, and percent improvement in models ability to correctly classify recidivists between gender, race and gender/race models. These findings suggest that further research should be conducted in this area.
Spin fluctuations and pairing symmetry in A$_{x}$Fe$_{2-y}$Se$_{2}$: dual effect of the itinerant and the localized nature of electrons

description: We investigate the spin fluctuations and the pairing symmetry in A$_{x}$Fe$_{2-y}$Se$_{2}$ by the fluctuation exchange approximation. Besides the on-site interactions, the next-nearest-neighbor antiferromagnetic coupling $J_{2}$ is also included. We find that both the itinerant and the localized natures of electrons are important to describe the recent experimental results of the spin fluctuations and the pairing symmetry. In particular, a small $J_{2}$ coupling can change the pairing gap from the d-wave symmetry to the s-wave symmetry. We have also studied the real-space structures of the gap functions for different orbits in order to gain more insight on the nature of the pairing mechanism.

A reevaluation of lower Colorado buff ware ceramics: Redefining the Patayan in southern Nevada
Creators: name: Seymour, Gregory Richard
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: Archaeological investigations in the Las Vegas area have collected significant ceramic data that have yet to be the subject of a systematic analysis. This thesis addresses issues relating to trade, exchange, and the manufacture of Lower Colorado Buff Ware ceramics found in the Las Vegas Valley. Archival research, and examination of representative ceramic assemblages from this region, address problems with existing regional models, including chronologic placement, ethnic origin, and culture change. Previous typological models, and past and present environmental conditions are presented, as well as a cultural historic context in which to place this data. Finally, a model of settlement and subsistence of the Patayan in southern Nevada is provided.

description: In most gene expression data, the number of training samples is very small compared to the large number of genes involved in the experiments. However, among the large amount of genes, only a small fraction is effective for performing a certain task. Furthermore, a small subset of genes is desirable in developing gene expression based diagnostic tools for delivering reliable and understandable results. With the gene selection results, the cost of biological experiment and decision can be greatly reduced by analyzing only the marker genes. An important application of gene expression data in functional genomics is to classify samples according to their gene expression profiles. Feature selection (FS) is a process which attempts to select more informative features. It is one of the important steps in knowledge discovery. Conventional supervised FS methods evaluate various feature subsets using an evaluation function or metric to select only those features which are related to the decision classes of the data under consideration. This paper studies a feature selection method based on rough set theory. Further K-Means, Fuzzy C-Means (FCM) algorithm have implemented for the reduced feature set without considering class labels. Then the obtained results are compared with the original class labels. Back Propagation Network (BPN) has also been used for classification. Then the performance of K-Means, FCM, and BPN are analyzed through the confusion matrix. It is found that the BPN is performing well comparatively.

Publisher: name: arXiv
Year: 2013
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: David Findley was born in Washington, DC on December 27, 1940. After attending high school in Lyndon, Kentucky, he earned a B.S. (1962) and M.A. (1963) in mathematics from the University of Cincinnati. He then lived in Germany, studying functional analysis under Gottfried Köthe, obtaining a Ph.D. from the University of Frankfurt in 1967. Returning to the United States, he served as a mathematics professor at the University of Cincinnati until 1975. Having transitioned from pure mathematics to statistical time series analysis, Findley took a new academic position at the University of Tulsa, during which time he interacted frequently with the nearby research laboratories of major oil companies and consulted regularly for Cities Service Oil Company (now Citgo). In 1980 he was invited to lead the seasonal adjustment research effort at the U.S. Census Bureau, and eventually rose to be a Senior Mathematical Statistician before his retirement in 2009. In 1966 he married Mary Virginia Baker, and they currently live in Washington, DC. David Findley has published more than 40 journal articles and book chapters, as well as dozens of technical reports and conference proceedings, many of which are heavily cited and influential. He has also published two edited volumes (1978 and 1981) that have had a substantial impact on the field of time series analysis. Numerous honors and awards have accrued to him, including ASA Fellow (1987), the Julius Shiskin award (1996) and the U.S. Department of Commerce Gold Medal (1997).

upstream oil production

description: This thesis estimates the carbon intensity of global upstream crude oil production with a specific focus on 2021. The study analyzes changes in the model from 2015 to 2021 and the impact of changes in global crude oil production practices and data progress. Alternative strategies for data processing and analysis are explored. The study also takes a closer look at specific countries to analyze the impact of factors like policy changes, technological advancements, and the COVID-19 pandemic on carbon intensity. The overall global carbon intensity decreases, largely due to the changes in the model. The findings reveal significant variability in carbon intensity across different regions and countries, with some regions seeing a decrease in carbon intensity while others experiencing an increase. The study provides insights into the most effective strategies for estimating carbon intensity and contributes to a better understanding of the carbon footprint of global upstream crude oil production, with implications for policymakers, industry stakeholders, and researchers working on reducing carbon emissions.
