description: We consider the Isgur-Wise function xi(omega) within a new modified version of a heavy-light chiral quark model. While early versions of such models gave too small absolute value of the slope, namely xi'(1) of about -0.4 to -0.3, we show how extended version(s) may lead to values around -1, in better agreement with recent measurements. This is obtained by introducing a new mass parameter in the heavy quark propagator. We also shortly comment on the consequences for the decay modes B --> D D-bar.

description: Review articles are a means to structure state-of-the-art literature and to organize the growing number of scholarly publications. However, review articles are suffering from numerous limitations, weakening the impact the articles could potentially have. A key limitation is the inability of machines to access and process knowledge presented within review articles. In this work, we present SmartReviews, a review authoring and publishing tool, specifically addressing the limitations of review articles. The tool enables community-based authoring of living articles, leveraging a scholarly knowledge graph to provide machine-actionable knowledge. We evaluate the approach and tool by means of a SmartReview use case. The results indicate that the evaluated article is successfully addressing the weaknesses of the current review practices.

title: Digital Labeling and Narrative Mapping in Mobile Remote Audio Signage: Verbalization of Routes and Generation of New Verbal Route Descriptions from Existing Route Sets
Creators: name: Tammineni, Tharun Tej
Publisher: name: Utah State University
Year: 2013

description: Independent navigation is a great challenge for people with visual impairments. In this project, we have designed and implemented an assisted navigation solution based on the ability of visually impaired travelers to interpret and contextualize verbal route descriptions. Previous studies have validated that if a route is verbally described in sufficient and appropriate manner then VI can use their orientation and mobility skills to successfully follow the route. In this project, we do not consider the issue how the VI will interpret the route descriptions, but we aim to identify and generate new verbal route descriptions from the existing route descriptions. We discuss different algorithms that we have used for extracting the landmarks, building graphs and generation of new route descriptions from existing route info.
Centrality Dependence of Two-Particle Correlations in Heavy Ion Collisions

Publisher: name: arXiv
Year: 2009
Subjects: subject: Nuclear Experiment (nucl-ex)

description: Data from the PHOBOS detector have been used to study two-particle correlations over a broad range of pseudorapidity. A simple cluster model parameterization has been applied to inclusive two-particle correlations over a range of centrality for both Cu+Cu and Au+Au collisions at sqrt(s_NN)=200GeV. Analysis of the data for Au+Au has recently been extended to more peripheral collisions showing that the previously-observed rise in cluster size with decreasing system size eventually reaches a maximum value. Model studies have been used to quantify the significant effect of limited detector acceptance on the extracted cluster parameters. In the case of Au+Au, correlations between a trigger particle with pT>2.5GeV and inclusive associated particles have also been studied. These reveal the presence of a `ridge' at small relative azimuthal angle which extends with roughly constant amplitude out to the largest relative pseudorapidity studied. The large phase-space coverage of the PHOBOS detector has enabled a quantitative understanding of the so-called `ZYAM' parameter used in the subtraction of the contribution of elliptic flow to these triggered correlations.

description: We report Monte Carlo simulations of the dynamics of a "chucker": a colloidal particle which emits smaller solute particles from its surface, isotropically and at a constant rate k_c. We find that the diffusion constant of the chucker increases for small k_c, as recently predicted theoretically. At large k_c the chucker diffuses more slowly due to crowding effects. We compare our simulation results to those of a "point particle" Langevin dynamics scheme in which the solute concentration field is calculated analytically, and in which hydrodynamic effects can be included albeit in an approximate way. By simulating the dragging of a chucker, we obtain an estimate of its apparent mobility coefficient which violates the fluctuation-dissipation theorem. We also characterise the probability density profile for a chucker which sediments onto a surface which either repels or absorbs the solute particles, and find that the steady state distributions are very different in the two cases. Our simulations are inspired by the biological example of exopolysaccharide-producing bacteria, as well as by recent experimental, simulation and theoretical work on phoretic colloidal "swimmers".

description: Recognition techniques allow robots to make proper planning and control strategies to manipulate various objects. Object recognition is more reliable when made by combining several percepts, e.g., vision and haptics. One of the distinguishing features of each object's material is its heat properties, and classification can exploit heat transfer, similarly to human thermal sensation. Thermal-based recognition has the advantage of obtaining contact surface information in realtime by simply capturing temperature change using a tiny and cheap sensor. However, heat transfer between a robot surface and a contact object is strongly affected by the initial temperature and environmental conditions. A given object's material cannot be recognized when its temperature is the same as the robotic grippertip. We present a material classification system using active temperature controllable robotic gripper to induce heat flow. Subsequently, our system can recognize materials independently from their ambient temperature. The robotic gripper surface can be regulated to any temperature that differentiates it from the touched object's surface. We conducted some experiments by integrating the temperature control system with the Academic SCARA Robot, classifying them based on a long short-term memory (LSTM) using temperature data obtained from grasping target objects.
title: Technology and the Self-Directed IEP: Improving Meeting Participation for Students with Severe Disabilities
Creators: name: Stringham, Crystal Ann
Publisher: name: Utah State University
Year: 2013

description: Students with a Specific Learning Disability (SLD) often experience challenges when transitioning to postsecondary education institutions after high school. A unique challenge involves filling out forms in order to registered for college. One of several components to a successful transition to postsecondary settings requires students to complete application forms. The purpose of this project is to examine the effects of direct instruction (DI) on increased performance of filling out college application forms of students with SLD in a special education classroom. Participants included eight high school students, ages 17 to 18, with a SLD. The intervention in this study involved teaching each participant through two sessions using DI to independently fill out forms required for college registration: an application for college undergraduate admission and an application for disability resource center services. The study collected pre- and post- assessment scores using a grading rubric and analyzed difference scores to assess the impact of DI on participant’s performance. The study also included a social validity measure that randomized pre- and post- forms that were independently examined and scored by a admission counselor and a disability resource center (DRC) representative. Using the rubric, most post-assessments for accuracy and completeness were higher than pre-assessments for both the college admission application and DRC forms. The admission counselor and DRC representative rated most post-application forms higher than pre-application forms. These findings suggest that transition supports are needed for students with SLD in filling out applications required for college. S2L script, verbalized, and used signs or gestures in the actual IEP meeting between 17.4% and 23.9% of 10 s intervals. These results have implications of improved self-determination measures for students with severe intellectual disabilities when taught to voice transition preferences and lead IEP meetings.

description: In this work we study, by a semigroup approach, a transmission problem based on biharmonic equations with boundary and transmission conditions, in two juxtaposed habitats. We give a result of existence and uniqueness of the classical solution in L p-spaces, for p $\in$ (1, +$\infty$), using analytic semigroups and operators sum theory in Banach spaces. To this end, we invert explicitly the determinant operator of the transmission system in L p-spaces using the E $\infty$-calculus and the Dore-Venni sums theory.

description: A simple statistical mechanical approach for studying multilayer adsorption of interacting polyatomic adsorbates (k-mers) has been presented. The new theoretical framework has been developed on a generalization in the spirit of the lattice-gas model and the classical Bragg-Williams (BWA) and quasi-chemical (QCA) approximations. The derivation of the equilibrium equations allows the extension of the well-known Brunauer-Emmet-Teller (BET) isotherm to more complex systems. The formalism reproduces the classical theory for monomers, leads to the exact statistical thermodynamics of interacting k-mers adsorbed in one dimension, and provides a close approximation for two-dimensional systems accounting multisite occupancy and lateral interactions in the first layer. Comparisons between analytical data and Monte Carlo simulations were performed in order to test the validity of the theoretical model. The study showed that: (i) the resulting thermodynamic description obtained from QCA is significantly better than that obtained from BWA and still mathematically handable; (ii) for non-interacting k-mers, the BET equation leads to an underestimate of the true monolayer volume; (iii) attractive lateral interactions compensate the effect of the multisite occupancy and the monolayer volume predicted by BET equation agrees very well with the corresponding true value; and (iv) repulsive couplings between the admolecules hamper the formation of the monolayer and the BET results are not good (even worse than those obtained in the non-interacting case).

We also present a new upper bound for the rate-distortion function for lossy-source coding with multiple decoders and side-information. Characterising this rate-distortion function is a long-standing open problem, and it is widely believed that the tightest upper bound is provided by Theorem 2 of Heegard and Berger's paper "Rate Distortion when Side Information may be Absent", \emph{IEEE Trans.

description: We discuss the scalable parallel solution of the Poisson equation within a Particle-In-Cell (PIC) code for the simulation of electron beams in particle accelerators of irregular shape. The problem is discretized by Finite Differences. Depending on the treatment of the Dirichlet boundary the resulting system of equations is symmetric or `mildly' nonsymmetric positive definite. In all cases, the system is solved by the preconditioned conjugate gradient algorithm with smoothed aggregation (SA) based algebraic multigrid (AMG) preconditioning. We investigate variants of the implementation of SA-AMG that lead to considerable improvements in the execution times. We demonstrate good scalability of the solver on distributed memory parallel processor with up to 2048 processors. We also compare our SAAMG-PCG solver with an FFT-based solver that is more commonly used for applications in beam dynamics.
title: Interagency Barriers and Facilitators in Transition Planning for Students with Disabilities
Creators: name: Taylor, Deanna Lynn
Publisher: name: Utah State University
Year: 2013

description: This study examined the barriers and facilitators identified by both vocational rehabilitation counselors and special educators in four states (Florida, Maryland, Oregon and Utah) regarding collaboration in transition planning. Two survey questionnaires were disseminated: one to vocational rehabilitation counselors and one to special educators in that requested information on perceptions of the level of knowledge on transition planning and activities, level of satisfaction, and open-ended questions for suggestions on how to improve collaboration between the two groups. The surveys were nearly identical and were designed to explore barriers that the two disciplines experience working with each other as well as ratings of recommendations to strengthen collaboration. The findings suggest that participation in transition and knowledge and skill level of transition varies in perception by special educators, with perception generally higher among vocational rehabilitation counselors, and that a number of barriers and facilitators exist to justify these perceptions. Respondents also suggested numerous recommendations for improving collaboration.
Evoluzione tematica e strutturale nel Canzoniere di Umberto Saba
Creators: name: Ciampi, Orlando
Publisher: name: University of British Columbia
Year: 2010

description: The thesis deals with some aspects of the Canzoniere , the major poetic work of Umberto Saba, who made his appearance on the Italian literary scene during the first decade of this century. The introduction and the first chapter are intended to provide summary background material on the literary-cultural situation in Trieste at the turn of the century within which Saba had necessarily to develop and work. Particular emphasis is placed on the fact that the city of Trieste, where the poet was born and lived most of his life, was culturally behind the times. This fact, together with Saba's own late cultural "awakening", contributed to the creation of a "peripheral" and "backward" style of poetry characterized by a touch of authentic realism which distinguishes and isolates him from his contemporaries, who were for the most part engaged in the attempts at poetic innovation. Another major characteristic of Saba's poetry derives from his acquaintance with Freud; in fact, the poet's interest in psychoanalysis constitutes the subject of the second chapter. Here the role which psychoanalysis plays in his poetry is defined by differentiating between "clinical" and "poetic" psychoanalysis, with reference to the poems written during the period in which he was undergoing psychoanalysis (1929-31) and to the writings in which Saba finally explicitly rejects psychoanalysis as an authentic source of poetic themes. The third chapter consists of a thematic and stylistic analysis of the poetry of the Canzoniere. with special emphasis on the early collections of Saba's work. The themes of these youthful poems are structurally related to those of the more recent works, where the poet, through a new sense of immediacy, transforms the motifs which dominated his adolescence, and in which a greater psychological clarity is accompanied by just as great a clarity of form.
Recursion relations for generalized Fresnel coefficients: Casimir force in a planar cavity
Creators: name: Tomas, Marin-Slobodan
Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Physics (quant-ph)

description: We emphasize and demonstrate that, besides using the usual recursion relations involving successive layers, generalized Fresnel coefficients of a multilayer can equivalently be calculated using the recursion relations involving stacks of layers, as introduced some time ago [M. S. Tomas, Phys. Rev. A 51, 2545 (1995)]. Moreover, since the definition of the generalized Fresnel coefficients employed does not imply properties of the stacks, these nonstandard recursion relations can be used to calculate Fresnel coefficients not only for local systems but also for a general multilayer consisting of various types (local, nonlocal, inhomogeneous etc.) of layers. Their utility is illustrated by deriving a few simple algorithms for calculating the reflectivity of a Bragg mirror and extending the formula for the Casimir force in a planar cavity to arbitrary media.

description: The Electric Vehicle (EV) Industry has seen extraordinary growth in the last few years. This is primarily due to an ever increasing awareness of the detrimental environmental effects of fossil fuel powered vehicles and availability of inexpensive Lithium-ion batteries (LIBs). In order to safely deploy these LIBs in Electric Vehicles, certain battery states need to be constantly monitored to ensure safe and healthy operation. The use of Machine Learning to estimate battery states such as State-of-Charge and State-of-Health have become an extremely active area of research. However, limited availability of open-source diverse datasets has stifled the growth of this field, and is a problem largely ignored in literature. In this work, we propose a novel method of time-series battery data augmentation using deep neural networks. We introduce and analyze the method of using two neural networks working together to alternatively produce synthetic charging and discharging battery profiles. One model produces battery charging profiles, and another produces battery discharging profiles. The proposed approach is evaluated using few public battery datasets to illustrate its effectiveness, and our results show the efficacy of this approach to solve the challenges of limited battery data. We also test this approach on dynamic Electric Vehicle drive cycles as well.

description: Many Visually Impaired individuals are managing their daily activities with the help of smartphones. While there are many vision-based mobile applications to identify products, there is a relative dearth of applications for extracting useful nutrition information. In this report, we study the performance of existing OCR systems available for the Android platform, and choose the best to extract the nutrition facts information from U.S grocery store packages. We then provide approaches to improve the results of text strings produced by the Tesseract OCR engine on image segments of nutrition tables automatically extracted by an Android 2.3.6 smartphone application using real-time video streams of grocery products. We also present an algorithm, called Skip Trie Matching (STM), for real-time OCR output error correction on smartphones. The algorithm’s performance is compared with Apache Lucene’s spell checker. Our evaluation indicates that the average run time of the STM algorithm is lower than Lucene’s. (68 pages)

description: The purpose of this case study was to determine the effects of femoral nerve block use during total knee arthroplasty on the return of quadriceps activation and functional outcomes in a single patient. This case study focused on an individual case consisting of simultaneous bilateral knee replacement. The individual received a femoral nerve block in one knee and traditional anesthesia in the other. We considered the improvement in functional outcomes following surgery. It was expected that the femoral nerve block will delay the activation of the quadriceps muscle and the return of functional measures. However, the femoral nerve block will modulate pain more successfully compared to the standard pain control procedures. This case study will also address the effect of femoral nerve blocks on quadriceps, particularly Vastus Medialis Oblique, reactivation following TKA. If so, for how long is quadriceps activation delayed. Is return of balance and proprioceptive control delayed following use of a femoral nerve block during TKA.

description: Loynes' distribution, which characterizes the one dimensional marginal of the stationary solution to Lindley's recursion, possesses an ultimately exponential tail for a large class of increment processes. If one can observe increments but does not know their probabilistic properties, what are the statistical limits of estimating the tail exponent of Loynes' distribution? We conjecture that in broad generality a consistent sequence of non-parametric estimators can be constructed that satisfies a large deviation principle. We present rigorous support for this conjecture under restrictive assumptions and simulation evidence indicating why we believe it to be true in greater generality.

description: The purpose of this project is to develop and present a training session for elementary school teachers and other Personnel who teach and work with English Language Learners (ELL). The training provides information on evidence based instructional strategies to help teachers improve their teaching methods with students who speak languages other than English. The lack of teacher knowledge in utilizing culturally and linguistically responsive teaching methods may be contributing to the over identification of ELLs in special education. This situation reinforces the need for additional teacher training for those who teach students from diverse cultural and linguistic backgrounds. This creative project fills a need in the field by (1) accessing teacher needs and presenting improved educational strategies for elementary school teachers serving ELLs, (2) developing and making available a training including input and responses for a needs assessment, (3) providing the initial training, (4) including a section on instructing and understanding how a second language acquisition process goes through a sequential series of stages, (5) measuring the effectiveness of the training via pre-post tests administered to the participants.
title: Probability Estimation in Random Forests
Creators: name: Li, Chunyang
Publisher: name: Utah State University
Year: 2013

description: Random Forests is a useful ensemble approach that provides accurate predictions for classification, regression and many different machine learning problems. Classification has been a very useful and popular application for Random Forests. However, it is preferable to have the probability of a membership rather than the simple knowledge that one belongs to whichever group. Votes and the regression method are current probability estimation methods that have been developed in Random Forests. In this thesis, we introduce two new methods, proximity weighting and the out-of-bag method, trying to improve the current methods. Several different simulations are designed to evaluate the new methods and compare them with the old ones. Finally, we use real data sets from UCI machine learning repository to further evaluate and compare those methods.

title: A Primary Document Analysis-Centered Curriculum in a Residential Treatment Center
Creators: name: Collette, Jared Peterson
Publisher: name: Utah State University
Year: 2013

description: This study examines the challenges and rewards of applying Stanford History Group’s Thinking Like a Historian program in the context of a residential treatment center to better understand the necessary modifications and adjustments that would be needed to successfully apply this program. The researcher used an action research methodology, an analytic autoethnographic journal, as well as student work to investigate student successes and challenges in learning history through the use of primary documents. The findings demonstrate that students did not successfully apply historical thinking even after explicit instruction, extensive modeling, and guided practice. The author argues that low literacy rates, background understanding, and self-efficacy, as well as classroom behavioral issues and limited class time inhibited student success. The author believes that in this context, primary document textual analysis is not the best means to teach or learn historical content, but may be more effective as a means for teachers to demonstrate historical concepts, and for students to demonstrate and apply understanding that they have already obtained.

A simulated approached is based off the work established by Longstaff and Schwartz (2001) and extended by Rambharat and Brockwell (2010). Downfalls of these methods are discussed, as are ways to improve upon them. Using Monte Carlo methods and particle filtering will lead to a platform where options are priced with greater detail. Also, these simulated methods lead to faster computing time allowing for a more efficient use of resources and a theoretical framework of pricing.

description: We discuss the correlated systematic theoretical uncertainties that may be ascribed to the next-to-leading order QCD theory used to predict the one-jet inclusive cross section in hadron collisions. We estimate the magnitude of these errors as functions of the jet transverse momentum and rapidity. The total theoretical error is decomposed into a set of functions of transverse momentum and rapidity that give a model for statistically independent contributions to the error. This representation can be used to include the systematic theoretical errors in fits to the experimental data.

description: Accurate and economical modeling of near-surface transport processes is a standing challenge for various engineering and atmospheric boundary-layer flows. In this paper, we address this challenge by utilizing a stochastic one-dimensional turbulence (ODT) model. ODT aims to resolve all relevant scales of a turbulent flow for a one-dimensional domain. Here ODT is applied to turbulent channel flow as stand-alone tool. The ODT domain is a wall-normal line that is aligned with the mean shear. The free model parameters are calibrated once for the turbulent velocity boundary layer at a fixed Reynolds number. After that, we use ODT to investigate the Schmidt ($Sc$), Reynolds ($Re$), and Peclet ($Pe$) number dependence of the scalar boundary-layer structure, turbulent fluctuations, transient surface fluxes, mixing, and transfer to a wall. We demonstrate that the model is able to resolve relevant wall-normal transport processes across the turbulent boundary layer and that it captures state-space statistics of the surface scalar-flux fluctuations. In addition, we show that the predicted mean scalar transfer, which is quantified by the Sherwood ($Sh$) number, self-consistently reproduces established scaling regimes and asymptotic relations. For high asymptotic $Sc$ and $Re$, ODT results fall between the Dittus--Boelter, $Sh\sim Re^{4/5}\,Sc^{2/5}$, and Colburn, $Sh\sim Re^{4/5}\,Sc^{1/3}$, scalings but they are closer to the former. For finite $Sc$ and $Re$, the model prediction reproduces the relation proposed by Schwertfirm and Manhart (Int. J. Heat Fluid Flow, vol. 28, pp. 1204-1214, 2007) that yields locally steeper effective scalings than any of the established asymptotic relations. The model extrapolates the scalar transfer to small asymptotic $Sc\ll Re_τ^{-1}$ (diffusive limit) with a functional form that has not been previously described.

description: Sender-receiver games are simple models of information transmission that provide a formalism to study the evolution of honest signaling and deception between a sender and a receiver. In many practical scenarios, lies often affect groups of receivers, which inevitably entangles the payoffs of individuals to the payoffs of other agents in their group, and this makes the formalism of pairwise sender-receiver games inapt for where it might be useful the most. We therefore introduce group interactions among receivers, and study how their interconnectedness in higher-order social networks affects the evolution of lying. We observe a number of counterintuitive results that are rooted in the complexity of the underlying evolutionary dynamics, which has thus far remained hidden in the realm of pairwise interactions. We find conditions for honesty to persist even when there is a temptation to lie, and we observe the prevalence of moral strategy profiles even when lies favor the receiver at a cost to the sender. We confirm the robustness of our results by further performing simulations on hypergraphs created from real-world data using the SocioPatterns database. Altogether, our results provide persuasive evidence that moral behaviour may evolve on higher-order social networks, at least as long as individuals interact in groups that are small compared to the size of the network.

description: We have been undertaking a systematic survey at 850 $μ$m based on a sample of four prototypical $z\sim2-3$ enormous Ly$α$ nebulae (ELANe) as well as their megaparsec-scale (Mpc-scale) environments to study the physical connections between ELANe and their coeval dusty submillimeter galaxies (SMGs). By analysing the SCUBA-2 data with self-consistent Monte Carlo simulations to construct the number counts, here, we report on the overabundance of 850 $μ$m-selected submillimeter sources around all the four ELANe, by a factor of 3.6$\pm$0.6 (weighted average) compared to the blank fields. This suggests that the excessive number of submillimeter sources are likely to be part of the Mpc-scale environment around the ELANe, corroborating the co-evolution scenario for SMGs and quasars; this is a process which may be more commonly observed in the ELAN fields. If the current form of the underlying count models continues toward the fainter end, our results would suggest an excess of the 850 $μ$m extragalactic background light by a factor of between 2-10, an indication of significant background light fluctuations on the survey scales. Finally, by assuming that all the excessive submillimeter sources are associated with their corresponding ELAN environments, we estimate the SFR densities of each ELAN field, as well as a weighted average of $Σ$SFR=1200$\pm$300 $M_\odot$ yr$^{-1}$ Mpc$^{-3}$, consistent with that found in the vicinity of other quasar systems or proto-clusters at similar redshifts; in addition, it is a factor of about 300 greater than the cosmic mean.

description: Spontaneous symmetry breaking is a general principle, that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model of elementary particles. I focus on manifestations of spontaneously broken symmetries in systems that are not Lorentz invariant, which include both, nonrelativistic systems as well as relativistic systems at nonzero density, providing a self-contained review of the properties of spontaneously broken symmetries specific to such theories. Topics covered include: (i) Introduction to the mathematics of spontaneous symmetry breaking and the Goldstone theorem. (ii) Minimization of Higgs-type potentials for higher-dimensional representations. (iii) Counting rules for Nambu-Goldstone bosons and their dispersion relations. (iv) Construction of effective Lagrangians. Specific examples in both relativistic and nonrelativistic physics are worked out in detail.

title: Relationship between Inflation News and High Frequency Stock Returns

description: Increases or decreases in stock prices will determine how much an investor’s wealth will shrink or grow in the stock market. One set of important factors that influences the stock market is macroeconomic indicators, like inflation news. The Consumer Price Index (CPI) and The Producer Price Index (PPI) are among the most important measures of inflation conditions and overall economic conditions. Adams, McQueen and Wood have already identified the relationship between inflation news and stock return. In their paper published in 2004, they found the unexpected increases in both PPI and CPI could cause stock prices to fall. In their paper, they explored the responses of stock intraday data and the unexpected changes in the Producer Price Index and Consumer Price Index before and on the news announcement date from 1977 to 1987.
