Use of Mnemonics in Learning Novel Foreign Vocabulary: Help or Hindrance?
Creators: name: Liu, Yeu-Ting
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2001

description: Research has consistently indicated that the use of mnemonic devices substantially enhances higher levels of retention in immediate recall of second language vocabulary words in comparison with other learning strategies. However, the evidence does not explain why the immediate benefits of mnemonic devices fail to extend to long-term retention. In addition, research on mnemonics has drawn mostly on the assessment of phonetic-hospitable languages such as English (as opposed to image-hospitable languages such as Chinese). To examine the use of mnemonic devices more thoroughly, this review will draw on psychological research on memory to discuss the efficacy of mnemonic methods, as opposed to rote rehearsal, in learning vocabulary in phonetic- and image-hospitable languages.

description: We analyze the Thermodynamic Bethe Ansatz equations for the mirror model which determine the ground state energy of the light-cone AdS_5 x S^5 superstring living on a cylinder. The light-cone momentum of string is equal to the circumference of the cylinder, and is identified with the inverse temperature of the mirror model. We show that the natural requirement of the analyticity of the Y-functions leads to the quantization of the temperature of the mirror model which has never been observed in any other models.

description: We analyze in detail the predictions of "trimaximal" neutrino mixing, which is defined by a mixing matrix with identical second column elements. This column is therefore identical to the second column in the case of tri-bimaximal mixing. We also generalize trimaximal mixing by assuming that the other rows and columns of the mixing matrix individually have the same forms as for tri-bimaximal mixing. The phenomenology of these new mixing scenarios is studied. We emphasize how trimaximal mixings can be distinguished experimentally from broken tri-bimaximal mixing.

The Effect of Environmental Factors on Bilingualism Among Chinese and Korean Americans
Creators: name: Shum, Lisa L.
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2001

description: For parents of immigrant children in the United States, the desire for their children to assimilate into the American culture and to learn English as quickly as possible is often mingled later with the frustration of not being able to communicate with their own children in the heritage or native language. While some immigrant children lose almost all ability to communicate in the heritage language, others grow up to be bilingual adults who are able to successfully maneuver between the two cultures. This paper will aim to explore some of the factors which have led some first and second generation Asian Americans to maintain the use of their heritage language and interest in their heritage culture. Specifically, factors such as exposure to the heritage language, personal motivation and family attitudes will be discussed.

description: Solving mathematical programming problems without the aid of electronic computers is very time consuming even for a mathematical model consisting of only a few constraints and variables. The objective of this report is to illustrate the use of mathematical programming computer routines available at Utah State University. Computer routines discussed are the International Business Machines (IBM), Mathematical Programming System (MPS) package, a quadratic programming routing, a zero-one integer programming routing, and a transportation code. The MPS package is a product of IBM; the quadratic programming routing was develop by the author: the last three routines were obtained from the IBM share library.
Source decks, 80-80 lists, and execution lists are available at the Department of Applied Statistics and Computer Science, the Department of Economics, and the Utah State Computer Center of Utah State University (USU) for all the computer programs indicated above excluding the MPS package. Each source deck, complete with job control language and sample problem input is read to run on the computer with the addition of a valid job card. The 80-80 list for each program is an exact duplicate of its corresponding deck. The execution list shows the output that is to result upon the execution of a given program and sample input deck. Within this report a discussing is prepared for each sample problem. First the problem is defined and the mathematical model for solution of the problem is developed. Second, explanation is provided on how the input cards are prepared, and finally an interpretation of the program output is included.
The MPS package is stored on disk at the U.S.U. Computer Center. Sample problems are provided in this report which illustrate how to use the MPS package. Also included in the report are references to where other sample problems may be found which illustrate the use of the MPS package.
Even though the Job Control Language (JCL) cards included in the illustrations vary with computer installation and with time, these are included so that the user will have an idea of the JCL needed to run the programs.
Various words within this report require a blank character. Since a blank character within a word would be confusing, the symbol "Δ" is used in place of the blank character.

description: A wide range of constraints can be compactly specified using automata or formal languages. In a sequence of recent papers, we have shown that an effective means to reason with such specifications is to decompose them into primitive constraints. We can then, for instance, use state of the art SAT solvers and profit from their advanced features like fast unit propagation, clause learning, and conflict-based search heuristics. This approach holds promise for solving combinatorial problems in scheduling, rostering, and configuration, as well as problems in more diverse areas like bioinformatics, software testing and natural language processing. In addition, decomposition may be an effective method to propagate other global constraints.

description: Imbalances of iron and dopamine metabolism along with mitochondrial dysfunction have been linked to the degeneration of dopaminergic neurons in Parkinson’s disease (PD). We have previously suggested a direct link between iron homeostasis and dopamine metabolism, as dopamine can increase cellular uptake of iron into macrophages thereby promoting oxidative stress responses. In this study, we investigated the interplay between iron, dopamine, and mitochondrial activity in neuroblastoma SH-SY5Y cells and human induced pluripotent stem cell (hiPSC)-derived dopaminergic neurons differentiated from a healthy control and PD patient with mutations in the α-synuclein (SNCA) gene. In SH-SY5Y cells, dopamine treatment resulted in regulation of transmembrane iron transporters and cellular iron accumulation. Furthermore, dopamine supplementation led to impaired mitochondrial respiration and related mitochondrial fitness, including reduced mtDNA copy number and citrate synthase activity, increased oxidative stress and impaired iron-dependent aconitase activity. In dopaminergic neurons derived from a healthy control individual, dopamine showed comparable effects as observed in SH-SY5Y cells. Of note, the hiPSC-derived PD neurons harboring an endogenous SNCA mutation presented with altered mitochondrial iron homeostasis, reduced mitochondrial capacity along with increased oxidative stress and subtle alterations of tricarboxylic acid cycle linked metabolic pathways as compared to control neurons. Importantly, dopamine treatment of these PD neurons promoted a rescue effect by improving mitochondrial respiration, activating antioxidant stress response, and normalizing altered metabolite levels involved in mitochondrial function. These observations provide evidence that dopamine affects iron homeostasis, intracellular stress responses and mitochondrial function in neuronal cells. The disturbed regulatory network in PD cells can be restored by supplementation of dopamine.
Investigating metabolomics and immune profiling as platforms to predict kidney transplant outcomes
Creators: name: Thachil, Amy
Publisher: name: University of British Columbia
Year: 2023

description: Despite advances in immunosuppression, kidney transplant success is limited by alloimmune mediated graft destruction and the gradual development of chronic rejection. Currently, we lack markers to predict the progression of the recipient alloimmune response at an early timepoint. Innate factors serve as potential targets to modulate the alloimmune environment and predict rejection risk. Metabolomics is a promising platform for identifying markers of alloimmune outcomes in kidney transplantation. Metabolite patterns reflect mechanisms occurring at the molecular, cellular, tissue, and organ level. Immune mechanisms persisting at the time of transplant produce a characteristic pattern of metabolites that may be detected in biospecimen. Additionally, cytokine profiling represents underlying immune signalling networks. By integrating patient metabolite and cytokine profiles, we develop a comprehensive assessment of recipient risk and identify targets for pre-transplant interventions. In the first study, we aimed to identify pre-transplant metabolite patterns related to i) early allograft inflammation (uCXCL10/Cr) and ii) early graft function (GFR) in pediatric renal transplant recipients. As part of this analysis, we applied a metabolite classifier that is predictive of chronic rejection in a cohort of adult kidney transplant recipients. In the third chapter, we summarized the existing literature on processing requirements for blood samples intended for use in metabolomics analyses. In the fourth chapter, we investigated the association between metabolome composition and age in a healthy pediatric cohort. We concluded by assessing differences in pre-transplant cytokine profiles associated with chronic rejection in adult kidney transplant recipients. We also compared the predictive utility of cytokine and metabolite profiling. We determined that pre-transplant metabolite patterns indicative of chronic rejection in adults are not associated with early graft inflammation or function in children. Furthermore, we report that age and body size are significant contributors to the measured pediatric metabolome and must be accounted for during biomarker identification. Our findings and literature review indicate the importance of standardized protocols to minimize sample processing-related metabolome perturbations. Finally, we identified differences in pre-transplant cytokine profiles related to chronic rejection and graft loss. We also report that the pre-transplant cytokine and metabolite profiles are correlated and improve in predictive capacity when combined.

description: Monolayers of colloidally synthesized cobalt-platinum nanoparticles of different diameters characterized by TEM (transmission electron microscopy) were deposited on structured silicon oxide substrates and characterized by SEM (scanning electron microscopy), GISAXS (grazing incidence x-ray scattering), and electric transport measurements. The highly ordered nanoparticle films show a thermally activated electron hopping between spatially adjacent particles at room temperature and Coulomb blockade at low temperatures. We present a novel approach to experimentally determine the particles charging energies giving values of 6.7-25.4 meV dependent on the particles size and independent of the interparticle distance. These observations are supported by FEM (finite element method) calculations showing the self-capacitance to be the determining value which only depends on the permittivity constant of the surrounding space and the particles radius.

Simulation of the current dynamics in superconductors: Application to magnetometry measurements

Publisher: name: arXiv
Year: 2009
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: A simple model for simulating the current dynamics and the magnetic properties of superconductors is presented. Short simulation times are achieved by solving the differential form of Maxwell's equations inside the sample, whereas integration is only required at the surface to meet the exact boundary conditions. The procedure reveals the time and position dependence of the current density and the magnetic induction (B) making it very convenient to apply field dependent material parameters for the simulation of magnetization loops, relaxation measurements, etc. Two examples, which are important for standard magnetometry experiments, are discussed. Firstly, we prove that evaluating the critical current density (J_c) from experiment by applying Bean's model reveals almost the exact J_c(B) behavior, if the evaluation is corrected by a simple numerical expression. Secondly, we show that the superconducting volume fraction of a sample can be directly determined from magnetization loops by carefully comparing experiment and simulation in the field range, where the current loops are differently oriented within the sample.

title: Bayesian Estimate of  System Reliability
Creators: name: Shah, Naresh
Publisher: name: Utah State University
Year: 1970

description: A Bayesian estimate of reliability for each component in the system of n-components, each exponentially distributed, is developed which utilizes the basic notion of loss in estimation theory. Here we assume that each component is independently dis­tributed. In reliability estimation, the loss associated with over­estimation is usually greater than the loss associated with under­estimation; and hence loss function can be a very useful tool. The prior distribution and loss function of reliability considered in this paper are flexible to be compatible with other situations in which reliability estimates are required. When the loss function is symmetric and no prior information is at hand, the resulting estimate is approximately the minimum variance unbiased estimate of reliability.
title: Computer Programs for Incomplete Block Designs
Creators: name: Miller, Fred
Publisher: name: Utah State University
Year: 1969

description: In most disciplines where research is involved, there exists an occasional problem of having minimal facilities and/or funds for conducting experiments. This often necessitates the use of designs known as incomplete block designs.
Since the calculations needed to provide an appropriate statistical analysis are somewhat tedious, particularJ..y in the larger designs, it is advantageous to have computer programs to do the necessary calculations.
There are several computer programs at Utah State University written in Fortran II language with Forcom subroutines that perform the analyses for incomplete block designs. These programs, for the most part, were authored by Justus Seely and Dr. Rex L. Hurst, Head, Department of Applied Statistics and Computer Science at U.S.U.
Only four of these available programs are covered in this paper. These programs are converted to Fortran IV language using the binary coded decimal system (BCD). The programs involved are Balanced Lattices, Designs Arranged in Replications, Designs Arranged in Groups of Replications, and Designs Not Arranged in Replications or Groups of Replications. The three latter programs will hereinafter be referred to as Type I, Type II, and Type III, respectively.
The programs will be written in double precision instead of single precision in order to increase computational accuracy. In single precision the number of significant digits carried accurately in the IBM 360 mod 44 computer is limited to seven. Since the numbers that represent the data need to be squared and summed, the size of number that could be used would have to be rather small, preferably less than four digits. With double precision the number of digits carried accurately is fourteen. This now presents the opportunity to use larger numbers to represent the data, but it is advisable to use numbers with less than six digits if possible.

description: Fitness can help to strengthen muscles, increase resistance to diseases, and improve body shape. Nowadays, a great number of people choose to exercise at home/office rather than at the gym due to lack of time. However, it is difficult for them to get good fitness effects without professional guidance. Motivated by this, we propose the first personalized fitness monitoring system, HearFit+, using smart speakers at home/office. We explore the feasibility of using acoustic sensing to monitor fitness. We design a fitness detection method based on Doppler shift and adopt the short time energy to segment fitness actions. Based on deep learning, HearFit+ can perform fitness classification and user identification at the same time. Combined with incremental learning, users can easily add new actions. We design 4 evaluation metrics (i.e., duration, intensity, continuity, and smoothness) to help users to improve fitness effects. Through extensive experiments including over 9,000 actions of 10 types of fitness from 12 volunteers, HearFit+ can achieve an average accuracy of 96.13% on fitness classification and 91% accuracy for user identification. All volunteers confirm that HearFit+ can help improve the fitness effect in various environments.

Publisher: name: Utah State University
Year: 1991

description: Chronic musculoskeletal pain can fundamentally alter a marital relationship and have significant effects on marital satisfaction for both the chronic pain patient and spouse. This paper is a critical review of literature on chronic musculoskeletal pain and marital adjustment. Nineteen empirical studies are evaluated and serve as the data base for conclusions and recommendations. Variables which may effect marital satisfaction such as sexual function, spouse solicitousness, effects on the psychological and physical health of the spouse and gender differences are identified. The impact of these variables on marriage and the spouse in particular, is discussed. Implications for further research in this area are considered.

We illustrate the method with several examples and we discuss its relationship to the Pontryagin maximum principle.

description: eSLEEP Europe 2023, eSLEEP, Virtual, Germany, 4 Oct 2023 - 6 Oct 2023
description: Sleep-disordered breathing (SDB) is prevalent in Alzheimer’s disease (AD). We assessed whether and how SDB affects neuroimaging biomarkers of AD, including amyloid-beta plaque burden (Aβ), regional uptake of fluorodeoxyglucose using positron emission tomography (rFDG-PET), grey matter volume (GMV), as well as cognitive scores and cerebrospinal fluid (CSF) biomarkers. We selected 757 subjects from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database based on cognitive status (AD, mild cognitive impairment (MCI), cognitively unimpaired (CU)), and SDB condition (with/without SDB). To ensure the reliability of our findings and considering imbalanced sample size across groups, we used a stratified subsampling approach generating 10,000 subsamples (n=10/group). We then selected 512 subsamples with matched covariates. The effect size of the cognitive status-SDB interaction was computed for each biomarker and cognitive score. For reference, we computed 1000 null models by shuffling group labels randomly. The average value of effect sizes for each biomarker in each region was estimated through bootstrapping with 10,000 iterations for both the main and null models and compared with the null model’s distribution. Linear regression models were next implemented to identify associations between the effect size on Aβ, rFDG, and GMV with the effect size on cognitive scores and CSF biomarkers across all subsamples. The cognitive status-SDB interaction had a medium-sized effect on Aβ, rFDG and GMV biomarkers in several brain areas. The effect sizes of the mentioned interactions on Aβ plaque burden in the right precuneus, left middle temporal gyrus, and left occipital fusiform gyrus were associated with the effect sizes of the interactions on cognitive scores. Further, the interaction effect sizes on CSF Aβ42 were related to the interaction effect sizes on Aβ in the right precuneus and posterior cingulate cortex, as well as rFDG in the left precuneus cortex and GMV in bilateral angular gyrus and right occipital fusiform gyrus. Effect sizes on CSF p-tau were also correlated with the effect sizes on Aβ in the left lateral occipital cortex and GMV in the left middle temporal gyrus. We observed that SDB interacts with neuroimaging and CSF biomarkers of AD. Specifically, SDB has a robust association with markers of Aβ pathology in PET and CSF relative to rFDG and GMV in the AD group. The cognitive status-SDB interaction on Aβ is associated with cognitive decline. This study further supports the hypothesis that SDB may precipitate AD pathology.

title: A Study of the Exponential Distirbutions and their Applications
Creators: name: Wang, Michael Chang-yu
Publisher: name: Utah State University

description: The exponential distribution is a widely known distribution i n statistical theory. It can be regarded as the continuous analogue of the Poisson distribution, discussed by S. D. Poisson in 1837. The Poisson is a limiting form of the Binomial distribution which can be t race d back as early as 1700, discussed by James Bernoulli. A paper by Marsden and Barratt (1911) on the radioactive disintegration of thorium gives a typical frequency distribution which follows the exponential law (8, p. 89). The exponential distribution has achieved importance recently in connection with the theory of stochastic process and has found a wide variety of applications in the fields of Physics, Biology, and Engineering. For instance, in the study of "Markov Processes" in continuous time, we notice that a very simple type of the process is the distribution of the time interval between any two successive events which follows the negative exponential distribution (1, p. 66-69).
Bulmer and Parzen have defined the exponential distribution in their books as a law of waiting times or as a law of time to failure such that any numerical valued random phenomena whose occurrences are random in time and independent of, what Bailey called, the past, present, and future state of the system may distribute exponentially (39, p . 262). Many physical, biological situations can be approximated by the exponential distribution, such as radioactive disintegration, telephone calls, mutant genes, infectious persons, the life of an electron tube, the time intervals between successive breakdowns of an electronic system, the time intervals between accidents, such as explosions in mines, etc. (34, 168-180). As an example, the numerical and graphical presentation of the time intervals in days between explosions in mines, involving more than 10 men killed, fro m December, 1875, to May, 1951, ta ken from Pearson (34, p. 168-180) are shown in Table l and Figure 1. It follows approximately the exponential distribution wit h mean time interval equal to 241 days .

description: BACKGROUND: Emergency Department (ED) is a zone of a hospital created to provide emergency care, and 3.5% of adult visits to the ED in the United States are often made by those with Chronic Kidney Disease (CKD). The purpose of this study is to examine ED visits and their association with age, gender, race, Socioeconomic status (SES), number of procedures, insurance type, comorbidities, length of stay, admission type, risk of mortality, CKD type, severity of illness, and number of chronic conditions in a cohort of patients with CKD. METHOD: The research methodology for this study is a quantitative correlational design study. The quantitative correlational research design measures the relationship between two variables, ED visits, and the 13 independent variables. Patient data is retrieved from the National Emergency Department Sample (NEDS). The researcher uses a Medical Loss Ratio (MLR) and Analysis of Variance (ANOVA) data tools to analyze the data collected from the study participants. RESULTS: There are 197,779 patients with CKD in the dataset. The results reveal that age is a significant predictor of likelihood of morality (p < .001), gender is not a significant predictor of likelihood of morality (p = .172), the overall logistic regression model is not statistically significant ( p = .127) for SES, the number of comorbidities is a significant predictor of likelihood of morality (p < .001), the number of procedures is a significant predictor of likelihood of morality ( p < .001), severity is a significant predictor of likelihood of morality (p < .001), and all predictors with the exception of SES were significant to predictors of length and hospital stay. CONCLUSION: According to the findings of the study, (a) an increase in age by one year would result in increased odds of mortality by 1.002 times, (b) gender was not a significant predictor of morality, (c) SES was a significant predictor of morality, (d) the number of comorbidities was a significant predictor of morality, (e) the number of procedures was a significant predictor of morality.

description: Mentoring is an important aspect of mathematics teacher education, and in particular, pre-service teacher education. Faculty at a large Midwestern university developed and refined a mentoring program designed to help pre-service secondary mathematics teachers, called Scholars, become future leaders in mathematics education. This paper describes how faculty mentors leveraged challenges in the mentoring program’s early stages based on their reflections and initial mentee outcomes to create a more effective mentoring program. Recommendations based on research and practice are provided for other university programs interested in mentoring future mathematics teachers.

description: This article examines the causes and addresses the prevention of unintended interconnections, particularly cross-connections, in novel urban water systems using the example of Qingdao, where a Resource Recovery Centre for the reuse of greywater and blackwater has been established for 12,000 inhabitants. With respect to cross-connections, this work incorporated both social-scientific and technical error analyses. The social-scientific error analysis systematically focused on the planning, implementation, and operational phases of the project. Organisational shortcomings were identified in four areas: (A) Coordination and consensus between the commissioned design institutes, (B) information in tenders, expertise, and awareness, (C) ownership by investors, and (D) time management. Based on empirical evidence, this article derives and discusses (eight) recommendations for good management, integrating technical and organisational measures aimed at preventing cross-connections. The pursuit of such measures is appropriate in order to prevent most types of misconnections — not just for the case under discussion, but for other novel urban water systems as well.

description: We study the CardPath constraint. This ensures a given constraint holds a number of times down a sequence of variables. We show that SLIDE, a special case of CardPath where the slid constraint must hold always, can be used to encode a wide range of sliding sequence constraints including CardPath itself. We consider how to propagate SLIDE and provide a complete propagator for CardPath. Since propagation is NP-hard in general, we identify special cases where propagation takes polynomial time. Our experiments demonstrate that using SLIDE to encode global constraints can be as efficient and effective as specialised propagators.

description: Low passing rates in developmental mathematics have been a serious concern for community colleges for many years. A course in Quantitative Literacy (QL) offers non-STEM students an alternative option to introductory algebra as a path to a degree. This paper describes the implementation and evolution of QL at the Borough of Manhattan Community College. Students enrolled in the 17 sections of QL were compared to a matched sample of students from Elementary Algebra. The students enrolled in QL in the Spring of 2013 were 175% more likely to have passed a credit-bearing mathematics course one year later, indicating that QL represents a valuable alternative for non-STEM college students placed into algebra level remediation. Further, the implementation and preliminary results of a corequisite course combining QL with college level Quantitative Reasoning (QR) are presented.

title: Tests of a Suggested Piezometric Method for Determining Hydraulic Conductivity of Saturated Soils

description: A major factor in the design of drainage systems is the hydraulic conductivity of the soil strata to be drained. Various methods for measuring the hydraulic conductivity of soils in both the field and the laboratory have been devised. In many cases, however, laboratory methods fail to give reliable data since the natural field conditions under which flow actually takes place cannot be duplicated in the laboratory. Hence a need exists for a field method for measuring hydraulic conductivity of soils in situ. When a large number of tests are to be performed in a given location, a simple, quick, accurate, and inexpensive method would be very desirable. After making studies of Lagunda de La Nava Project in Spain for the purpose of analyzing irrigation, drainage, and salinity problems, Professor J. E. Christiansen (1964) Consultant for the Hydrotechnic Corporation, suggested a simple piezometer method for determining the relative hydraulic conductivity of the soils. Using this method and the formula suggested by Professor Christiansen, several tests were performed in various locations. The object of this report is to describe this piezometer method for determining the relative hydraulic conductivity of the soil strata and to present the results obtained in a limited field study, together with conclusions and recommendations.

description: Marine oil spill incidents are detrimental to both natural environment and human health. Water quality, marine ecosystems, and shoreline conditions can be deteriorated by the spilt oil. Swift and efficient response to an oil spill is crucial to minimize the adverse consequences. However, the oily waste generated from response operations may also become a challenge, requiring careful waste management strategies. Widely used oil spill response methods (OSRMs) include mechanical containment and recovery (MCR), in-situ burning, and the use of chemical dispersants. Choosing the most suitable method is a complex process depending on various factors. Among OSRMs, MCR is the most effective in removal of spilt oil from the marine environment. The management of oily wastewater generated during MCR requires careful attention, as it comprises a significant portion of overall oily waste. This study developed multiple tools to aid selecting OSRMs in harsh and remote offshore waters. These selection tools employ machine learning techniques and historical response data to predict appropriate OSRMs for new incidents. The tools were developed in MATLABTM using various artificial intelligence and soft computing techniques, such as fuzzy decision tree (FDT), Gaussian process regression (GPR), and artificial neural network, individually or in combination. FDT-based tools were also integrated with regression analysis techniques and an optimization algorithm to enhance their performance. Optimized FDTs integrated with regression analysis and GPR were found to be the most effective techniques based on the prediction power. Furthermore, this study developed an integrated optimization tool to efficiently manage the mechanical response process. This tool aims to minimize the time and cost associated with MCR and oily wastewater management (OWM) and the volume of weathered oil during the operation. The tool encompasses three components of multi-objective optimization, oil weathering process, and MCR and OWM operational agents, simulating detailed response procedures. Applying the tool to a case study in Canada led to a notable reduction in the time and cost of the entire response, and a considerable increase in the volume of recovered oil. It provides an effective approach to manage response process, and significantly reduces the environmental and socio-economic impacts of oil spill incidents.
