description: Hybrid localization in GNSS-challenged environments using measured ranges and angles is becoming increasingly popular, in particular with the advent of multimodal communication systems. Here, we address the hybrid network localization problem using ranges and bearings to jointly determine the positions of a number of agents through a single maximum-likelihood (ML) optimization problem that seamlessly fuses all the available pairwise range and angle measurements. We propose a tight convex surrogate to the ML estimator, we examine practical measures for the accuracy of the relaxation, and we comprehensively characterize its behavior in simulation. We found that our relaxation outperforms a state of the art SDP relaxation by one order of magnitude in terms of localization error, and is amenable to much more lightweight solution algorithms.

description: Climate change is a commons problem of global proportions. The effects of climate change threaten not only the natural world, but also the human systems that we have established (IPCC 2014, 4). The devastating effects of climate change will not be confined to those regions of the world that have contributed the most to this problem. Already, every continent and ocean has been touched by climate change (IPCC 2014, 4).
title: Laboratory Approach to Modeling the Initiating Mechanism in the Piping Failure of Sandy Soils
Creators: name: Olorunsola, Olalekan O.
Publisher: name: Utah State University
Year: 2010

description: This research intends to develop a testing apparatus to measure the critical gradient in sandy soils. The designed apparatus will be used in subsequent studies to develop a relationship between critical hydraulic gradient, soil properties and the inclination of the exit face.
This study evaluates several design modification to assess the effects of the modifications, and develop a design that most closely models the field mechanism of piping initiation. The design is initiated from a conceptual design and is executed into the first version. This design is called the Alpha Version. The next version, or more precisely, the Beta Version, corrects the inadequacies of the Alpha Version. Further modification would result in the Final Version.

description: Background: Common existing phylogenetic tree visualisation tools are not able to display readable trees with more than a few thousand nodes. These existing methodologies are based in two dimensional space. Results: We introduce the idea of visualising phylogenetic trees in three dimensional hyperbolic space with the Walrus graph visualisation tool and have developed a conversion tool that enables the conversion of standard phylogenetic tree formats to Walrus' format. With Walrus, it becomes possible to visualise and navigate phylogenetic trees with more than 100,000 nodes. Conclusion: Walrus enables desktop visualisation of very large phylogenetic trees in 3 dimensional hyperbolic space. This application is potentially useful for visualisation of the tree of life and for functional genomics derivatives, like The Adaptive Evolution Database (TAED). ©2004 Hughes et al, licensee BioMed Central Ltd.

description: A phenomenological analysis of the experimental measurements of transverse momentum spectra of identified charged hadrons and strange hyperons in Pb-Pb and Xe-Xe collisions at the LHC is presented. The analysis is based on the relativistic fluid dynamics description implemented in the numerically efficient \textsc{Fluid{\it u}M} approach. Building on our previous work, we separate in our treatment the chemical and kinetic freeze-out, and incorporate the partial chemical equilibrium to describe the late stages of the collision evolution. This analysis makes use of Bayesian inference to determine key parameters of the QGP evolution and its properties including the shear and bulk viscosity to entropy ratios, the initialisation time, the initial entropy density, and the freeze-out temperatures. The physics parameters and their posterior probabilities are extracted using a global search in multidimensional space with modern machine learning tools, such as ensembles of neural networks. We employ our newly developed fast framework to assess systematic uncertainties in the extracted model parameters by systematically varying key components of our analysis.

description: The phase transition behaviour of PbTiO3 and BaTiO3 under (111) epitaxial strain is investigated using density-functional theory calculations. From tensile strains of +0.015 to compressive strains of -0.015, PbTiO3 undergoes phase transitions from C2 through two Cm phases and then to R3m. The total polarisation is found to be almost independent of strain. For the same range of strains BaTiO3 undergoes phase transitions from a single Cm phase, through R3m and then to R-3m. In this case the application of compressive strain inhibits and then completely suppresses the polarisation on transition to the non-polar R-3m phase.

Year: 2012

description: This portfolio was written for the Master of Second Language Teaching Program (MSLT). It consists of the author's personal teaching philosophy as it relates to teaching ESL (English as a Second Language). It includes papers that demonstrate the author's beliefs on teaching English as a Second Language especially academic language instruction. It includes the author's personal teaching philosophy as it relates to teaching ESL. This is followed by three artifacts: the value of children's literature in English as a second language instruction, navigating academic language, and asking clarifying questions. The portfolio also includes a research proposal, the impact of audio-book read along, as a home component on second language (L2) Literacy. It concludes with an annotated bibliography of works that have influenced the author's teaching philosophy.
"The Value of Children's Literature in English as a Second Language Instruction" demonstrates the author's belief that literature should have a place in the L2 classroom. It discusses the many benefits the use of literature can have includ ing bolstering students' background knowledge and building a rich vocabulary. "Navigating Academic Language" discusses the need for L2 learners to develop their academic English
proficiency to promote their success in school. "The Importance of Clarification Requests in SLA (Second Language Acquisition)" stresses the importance of L2 learners gaining clarification on problem utterances they encounter in their academic classes to assist them in their academic as well as linguistic development.
The final paper, "The Impact of Audio-Book Read Along as a Home Component on L2 Literacy" is a research proposal. The research would seek to understand the benefits of an audio-book program. This would help determine if the costs of setting up an audio-book library would be academically beneficial for this population of students.
All portions of this portfolio support the author's belief that the academic success of L2 learners is closely linked to their language and cultural proficiency in L2. And as a result of this belief, L2 teaching should have a strong academic component. The portfolio concludes with an annotated bibliography, a collection of works that have influenced the author's teaching philosophy.
Topological superconductivity mediated by magnons of helical magnetic states

description: We recently showed that spin fluctuations of noncoplanar magnetic states can induce topological superconductivity in an adjacent normal metal [Mæland et al., Phys. Rev. Lett. 130, 156002 (2023)]. The noncolinear nature of the spins was found to be essential for this result, while the necessity of noncoplanar spins was unclear. In this paper we show that magnons in coplanar, noncolinear magnetic states can mediate topological superconductivity in a normal metal. Two models of the Dzyaloshinskii-Moriya interaction are studied to illustrate the need for a sufficiently complicated Hamiltonian describing the magnetic insulator. The Hamiltonian, in particular the specific form of the Dzyaloshinskii-Moriya interaction, affects the magnons and by extension the effective electron-electron interaction in the normal metal. Symmetry arguments are applied to complement this discussion. We solve a linearized gap equation in the case of weak-coupling superconductivity. The result is a time-reversal-symmetric topological superconductor, as confirmed by calculating the topological invariant. In analogy with magnon-mediated superconductivity from antiferromagnets, Umklapp scattering enhances the critical temperature of superconductivity for certain Fermi momenta.

title: Communication at the Heart of Teaching Chinese as a Foreign Language
Creators: name: Zhao, Haitao
Publisher: name: Utah State University
Year: 2016

description: This portfolio demonstrates the author’s beliefs regarding effective methods for foreign language teaching. The first section includes the author’s teaching philosophy which addresses three themes: communicative language teaching (CLT), bringing authentic material into the foreign language classroom with the integration of technology, and developing lower-graders’ literacy in the Chinese dual-language immersion (DLI) classroom. Following the teaching philosophy are three artifacts that were originally written as term papers for courses in the Master of Second Language Teaching (MSLT) program. First, the language artifact reviews the approaches of asynchronous computer-mediated communication (ACMC) and synchronous computer-mediated communication (SCMC) for online tandem learning programs. Second, the literacy artifact demonstrates the importance of developing lower-graders’ literacy skills in the Chinese DLI classroom. Third, the cultural artifact focuses on examining Chinese requests strategies. Finally, the annotated bibliography containing three topics documents the authors’ journey of
learning to be an effective language teacher in the MSLT program. The first topic is about the author’s acknowledgement of the CLT methodology with reading both compliments and criticism from others’ perspectives. In addition, the second topic is a process of realizing the significance of incorporating technology to facilitate foreign language learning in this digital era. Lastly, the third topic talks about the author’s understanding of the importance of DLI education and her interest of being a DLI teacher in the future.
title: High Speed Digital Sample Rate Conversion for a Real-Time Ground Station Receiver
Creators: name: Carrick, Brian Joseph
Publisher: name: Utah State University
Year: 2016

description: Small satellites are becoming a popular spacecraft option because of their low cost, and complexity. Past small satellites had simple communication systems with low data rates that rarely exceeded 38.4 kbps. Engineers, researchers, and students, from Space Dynamics Laboratory and Utah State University, have recently created and launched a pair of small satellites called the Dynamic Ionosphere CubeSat Experiment (DICE). This mission was revolutionary because of its high-speed data link, with data rates up to 1.5 Mbps.
Due to the high-speed data link, it was necessary to create a ground station capable of receiving and processing the received data. For the DICE mission the ground station developed was not capable of receiving and processing the data in real-time. Because the current ground station was not capable of running in real-time it became necessary to develop a real-time solution. The real-time ground station receiver is a hardware solution, that implements signal processing algorithms in an FPGA in real-time. This report describes the theory, design, simulation, implementation, and testing of the sampling rate conversion portion of the system, as well as, other work that can be done to complete the real-time ground station receiver.

description: Background: Modern developmental biology relies heavily on the analysis of embryonic gene expression patterns. Investigators manually inspect hundreds or thousands of expression patterns to identify those that are spatially similar and to ultimately infer potential gene interactions. However, the rapid accumulation of gene expression pattern data over the last two decades, facilitated by high-throughput techniques, has produced a need for the development of efficient approaches for direct comparison of images, rather than their textual descriptions, to identify spatially similar expression patterns. Results: The effectiveness of the Binary Feature Vector (BFV) and Invariant Moment Vector (IMV) based digital representations of the gene expression patterns in finding biologically meaningful patterns was compared for a small (226 images) and a large (1819 images) dataset. For each dataset, an ordered list of images, with respect to a query image, was generated to identify overlapping and similar gene expression patterns, in a manner comparable to what a developmental biologist might do. The results showed that the BFV representation consistently outperforms the IMV representation in finding biologically meaningful matches when spatial overlap of the gene expression pattern and the genes involved are considered. Furthermore, we explored the value of conducting image-content based searches in a dataset where individual expression components (or domains) of multi-domain expression patterns were also included separately. We found that this technique improves performance of both IMV and BFV based searches. Conclusions: We conclude that the BFV representation consistently produces a more extensive and better list of biologically useful patterns than the IMV representation. The high quality of results obtained scales well as the search database becomes larger, which encourages efforts to build automated image query and retrieval systems for spatial gene expression patterns. © 2004 Gurunathan et al; licensee BioMed Central Ltd.

description: We consider the gravity in the system consisting of the Bogomol'nyi-Prasad-Sommerfield (BPS) D3-brane embedded in the flat background geometry, produced by the solutions of the supergravity. The effective action for this system is represented by the sum of the Hilbert-Einstein and DBI actions. We derive the Wheeler-De Witt equation for this system and obtain analytical solutions in some special cases. We also calculate tunneling probability from Planckian size of D3-brane to the classical regime.
Handwritten Digit Recognition by Spin Waves in a Skyrmion Reservoir

description: By performing numerical simulations for the handwritten digit recognition task, we demonstrate that a magnetic skyrmion lattice confined in a thin-plate magnet possesses high capability of reservoir computing. We obtain a high recognition rate of more than 88%, higher by about 10% than a baseline taken as the echo state network model. We find that this excellent performance arises from enhanced nonlinearity in the transformation which maps the input data onto an information space with higher dimensions, carried by interferences of spin waves in the skyrmion lattice. Because the skyrmions require only application of static magnetic field instead of nanofabrication for their creation in contrast to other spintronics reservoirs, our result consolidates the high potential of skyrmions for application to reservoir computing devices.

description: China's rural e-commerce industry has experienced significant growth, driven by government support and industrial policies. Policies such as the "Circular on the creation of demonstration zones for agricultural modernization in 2022" and "Opinions on strengthening the construction of county commercial systems to promote rural consumption" have provided a favorable environment for rural e-commerce development. Guangdong Province, in particular, is actively working to enhance its rural e-commerce industry, expanding its presence in 53 demonstration counties and prioritizing rural consumption as a key strategy for economic growth. To achieve high-quality development in rural e-commerce, it is essential to focus on improving the quality of express delivery services and strengthening logistics support for rural rejuvenation. This paper explores the significance of logistics support in promoting the high-quality development of rural e-commerce in Guangdong Province.
title: An Instructional Module on Permaculture Design Theory for Landscape Architecture Students

description: Permaculture guides designers to mimic patterns and relationships found in nature. It is a design theory that tailors toward many people’s desire for more sustainable living. This theory offers a unique set of design principles that are very implementable into the design process and could be of great interest to landscape architects.
The purpose of this study was to develop and implement an instructional module for landscape architecture students at Utah State University for two consecutive years. Project-based learning was implemented in order to help students better understand permaculture design theory. Effectiveness of the module was measured through an evaluation of post-module survey responses and student design projects. Results from the second year of teaching showed an increase from the first year in student interest, understanding, and desire to learn more about permaculture design theory.

On the role of the time scale Delta t in Bose-Einstein correlations

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The time scale $Δt$ parameter, which appears in the Bose-Einstein Correlations (BEC) treated in term of the Heisenberg uncertainty relations, is reexamined. Arguments are given for the role of $Δt$ as a measure of the particles' emission time rather than representing the strength property of the correlated particles. Thus in the analyzes of the $Z^0$ hadronic the $Δt$ given value of ~$10^{-24}$ seconds is the particles' emission time prescribed by the $Z^0$ lifetime. In heavy ion collisions $Δt$ measures the emission time duration of the particles produced from a nucleus of atomic number $A$ which is here shown to be equal to $Δt =(m_πa^2)/(\hbar c^2})*A^{2/3}$ where a is about 1 fm, that is, proportional to the nucleus surface area. This dependence agrees rather well with the experimental $Δt$ values deduced from the BEC analyzes of heavy ion collisions.

description: We study the population of Galactic planetary Nebulae (PNe) and their central stars (CSs) through the analysis of their heliocentric distances and Galactic distribution. Distances are obtained by means of a revised statistical scale, based on an astrometrically-defined sample of CSs parallaxes from Gaia DR3 as calibrators. The statistical scale is applied to infer distances of a significant number (~850) of Galactic PNe, for which we deliver a new catalog of PN distances. By adopting a circular velocity curve of the Galaxy, we also derive 3D peculiar velocities from DR3 proper motions and published radial velocities of a large sample (~300) of PN CSs. We date PN progenitors based both on the best chemical abundances culled from the literature and on CS kinematic properties, finding a confirmation of the first method with the second. The slope of the radial oxygen gradient of the Galactic Disk traced by the complete PNe sample amounts to -0.0144 +/- 0.00385 [dex/kpc]. Furthermore, by distinguishing between PNe with old (> 7.5 Gyr) and young (< 1 Gyr) progenitors, we estimate the gradient to be respectively -0.0121 +/- 0.00465 and -0.022 +/- 0.00758 [dex/kpc], thus disclosing a mild steepening since Galaxy formation, with a slope change of 0.01 dex. These results are in broad agreement with previous PN studies, but now based on DR3 Gaia analysis, and also in agreement with what traced by most other Galactic probes.

A model for working with dysfunctional blue collar families
Creators: name: Nickerson, William James Murdoch
Publisher: name: University of British Columbia
Year: 2010

description: The central purpose of this thesis was the development of a model of intervention with the dysfunctional blue collar family. The overall discussion focused on two issues. The first involved the delineation of a method of treatment for the blue collar family. A specific approach was determined through an examination of some of the characteristics of the blue collar family. The second major area of discussion centered on the combination or pairing of two divergent psychological approaches to compliment the proposed treatment style. The Rogerian approach and a behavior modification approach were examined and the advantages of each as an overall treatment method were utilized in the proposed model. The sources of information for the study came from personal clinical experience in working with blue collar families and from a review of current relevant literature. The literature reviewed covered four main subject areas: a) a social learning or behavior modification approach, b) the use of parents as change agents for their children, c) the Rogerian therapeutic relationship, and d) some characteristics of the blue collar family. The review of the literature and personal clinical experience resulted in a proposed treatment model for therapeutic intervention with the blue collar family. The model contains six components which come under three main headings. They are: A. Assessment. A1. Role-Induction Interview; A2. Intake Interview; A3. Baseline. B. Treatment. B1. Parent Training Sessions; B2. Assessment of Change. C. Evaluation. C1. Consultative Follow-Up. Some Implications for further research regarding the model presented include a comparison of the proposed model with other models of family intervention. Investigation of the dynamics of the relationship between the therapist and the parent and/or the parent and the child might also result in contributions to the field of family therapy.
title: Analysis of the Relationship Between Economic Freedom and the Stability of Stock Prices
Creators: name: Qiu, Jinyu
Publisher: name: Utah State University
Year: 2016

description: The objective of this study is to re-investigate the relationship between macroeconomic factors and the price stability of individual securities by using an American Depositary Receipts (ADRs) sample. Instead of using a large sample of 327 ADRs in Blau, Brough, and Thomas’ (2013) study, I focused on a panel data of 150 ADRs from 30 countries over the 2003-2007 period. Empirical evidence is provided to support whether economic freedom in the ADR home country reduces ADR volatility. In this replication study, the analysis is conducted within the pooled ordinary least square as the method of estimation. The findings show that economic freedom does have significant impact on ADR volatility.

description: Background: The earliest fossil evidence of terrestrial animal activity is from the Ordovician, ∼450 million years ago (Ma). However, there are earlier animal fossils, and most molecular clocks suggest a deep origin of animal phyla in the Precambrian, leaving open the possibility that animals colonized land much earlier than the Ordovician. To further investigate the time of colonization of land by animals, we sequenced two nuclear genes, glyceraldehyde-3-phosphate dehydrogenase and enolase, in representative arthropods and conducted phylogenetic and molecular clock analyses of those and other available DNA and protein sequence data. To assess the robustness of animal molecular clocks, we estimated the deuterostome-arthropod divergence using the arthropod fossil record for calibration and tunicate instead of vertebrate sequences to represent Deuterostomia. Nine nuclear and 15 mitochondrial genes were used in phylogenetic analyses and 61 genes were used in molecular clock analyses. Results: Significant support was found for the unconventional pairing of myriapods (millipedes and centipedes) with chelicerates (spiders, scorpions, horseshoe crabs, etc.) using nuclear and mitochondrial genes. Our estimated time for the divergence of millipedes (Diplopoda) and centipedes (Chilopoda) was 442 ± 50 Ma, and the divergence of insects and crustaceans was estimated as 666 ± 58 Ma. Our results also agree with previous studies suggesting a deep divergence (∼1100 - 900 Ma) for arthropods and deuterostomes, considerably predating the Cambrian Explosion seen in the animal fossil record. Conclusions: The consistent support for a close relationship between myriapods and chelicerates, using mitochondrial and nuclear genes and different methods of analysis, suggests that this unexpected result is not an artefact of analysis. We propose the name Myriochelata for this group of animals, which includes many that immobilize prey with venom. Our molecular clock analyses using arthropod fossil calibrations support earlier studies using vertebrate calibrations in finding that deuterostomes and arthropods diverged hundreds of millions of years before the Cambrian explosion. However, our molecular time estimate for the divergence of millipedes and centipedes is close to the divergence time inferred from fossils. This suggests that arthropods may have adapted to the terrestrial environment relatively late in their evolutionary history. © 2004 Pisani et al; licensee BioMed Central Ltd.

There are a number of options for defining the diameter of a convex body that fall apart when we consider non-symmetric gauges. These definitions correspond to different symmetrizations of the gauge, i.e. means of the gauge $C$ and its origin reflection $-C$.

description: The level crossing and inverse statistics analysis of DAX and oil price time series are given. We determine the average frequency of positive-slope crossings, $ν_α^+$, where $T_α =1/ν_α^+ $ is the average waiting time for observing the level $α$ again. We estimate the probability $P(K, α)$, which provides us the probability of observing $K$ times of the level $α$ with positive slope, in time scale $T_α$. For analyzed time series we found that maximum $K$ is about 6. We show that by using the level crossing analysis one can estimate how the DAX and oil time series will develop. We carry out same analysis for the increments of DAX and oil price log-returns,(which is known as inverse statistics) and provide the distribution of waiting times to observe some level for the increments.

Creators: name: Jones, Scott E.
Publisher: name: Utah State University
Year: 2016

description: This paper looks at the 17 years leading up to Martin Luther King Jr. day becoming a non-traded holiday and the 17 years since to see if this exogenous shock to the market resulted in abnormal rates of return on the day before the holiday (known as the pre-holiday effect). I also look to see if evidence of abnormal returns still exists before Christmas and July 4th during the same time period. I used daily data on the equally-weighted universe of stocks, the value-weighted universe of stocks, and the S&P 500. I find that while there is some evidence of pre-Christmas abnormal rates of return, there is no evidence of such anomalies before July 4th. My results also show that returns do not change around the time when Martin Luther King Jr. Day became a non-traded holiday.

description: REFeAsO (RE1111; RE: rare earth) belongs to the 1111 family of iron-based superconductors (FBS), which illustrates the enhancement of the superconducting transition (Tc) with smaller radii of RE. However, the synthesis of the 1111 phase with a heavy rare-earth is always challenging. In this paper, we report the optimization of the growth and superconducting properties of F-doped GdFeAsO1-xFx bulks by preparing the samples in a wide temperature range (700-1100°C) at ambient pressure. The optimized synthesis parameters are concluded based on structural, microstructural, transport, and magnetic measurements. These findings suggest that the optimal conditions for preparing F-doped Gd1111 bulks involve a two-step process at 900°C for 61 hours at ambient pressure, which is lower than previously reported. The optimized samples have revealed the superconducting transition temperature (Tconset) of 43 K for GdFeAsO0.83F0.17. The first-time reported critical current Jc value for this Gd1111 is observed of the order of 10^3 (A/cm^2) at 0 T and 5 K. Our investigation also concluded that highly pure precursors, particularly gadolinium metal, are required to achieve the superconducting properties of F-doped Gd1111. A high growth pressure of 1 GPa reduces the superconducting properties of F-doped Gd1111.

description: In the last few years, a countless number of permissioned blockchain solutions have been proposed, with each one to claim that it revolutionizes the way of the transaction processing along with the security and privacy preserving mechanisms that it provides. Hyperledger Fabric is one of the most popular permissioned blockchain architectures that has made a significant impact on the market. However, there are only few papers of finding architectural risks regarding the security and the privacy preserving mechanisms of Hyperledger Fabric. This paper separates the attack surface of the blockchain platform into four components, namely, consensus, chaincode, network and privacy preserving mechanisms, in all of which an attacker (from inside or outside the network) can exploit the platform's design and gain access to or misuse the network. In addition, we highlight the appropriate counter-measures that can be taken in each component to address the corresponding risks and provide a significantly secure and enhanced privacy preserving Fabric network. We hope that by bringing this paper into light, we can aid developers to avoid security flaws and implementations that can be exploited by attackers but also to motivate further research to harden the platform's security and the client's privacy.

description: Real-time PCR methodology can successfully quantitate microchimeric cell populations at a concentration of 100 microchimeric cells/100,000 host cells; however, it has not been successful in quantitating DNA from trace numbers of microchimeric white blood cells which we reported are present in murine peripheral blood at a concentration as low as 2/100,000 host cells. We report methodology using primers for a portion of the H2-kb murine histocompatibility sequence, specific for the C57BL/6J mouse. When these primers were used in the presence of 11,000 μM primer, a 20-fold increase in the median manufacturer's recommended concentration, the assay could be optimized to detect 34 pg of C57BL/6J DNA in a background of 2.5 μg of carrier BALB/cJ DNA (1/100,000). These conditions resulted in a detection limit half as sensitive as that found when no carrier DNA was present.
title: Frictional Heating of Fault Surfaces Due to Seismic Slip: Experimental Studies on the Hematite to Magnetite Transition and Federal and Private Landownership's Effect on Oil and Gas Drilling and Production in the Southwestern Wyoming Checkerboard
Creators: name: Jenkins, David W.
Publisher: name: Utah State University

description: This report is a two-part presentation of research within in the fields of rock mechanics and natural resource economics. The first chapter addresses the use of iron oxide oxidation state and thus mineral transitions as a method for determining the frictional temperature rise achieved during an earthquake. Experimental literature on the hematite to magnetite transition is reviewed. Magnetite from transformed or reacted hematite forms between 300-1240 °C. Design and experimental results for a rotary shear apparatus in which hematite is deformed are reported. The measured coefficient of friction for synthetic hematite gouge is 0.38 ±0.03. The second chapter is an investigation of oil and gas production outcomes between federal and private land using a randomized treatment of land ownership. The data comprises oil and gas well drilling and production records located in the railroad land checkerboard, southwestern Wyoming. Spatial and graphical analysis of production and drilling records reveal that federal mineral leases are developed systemically later than private land.

description: We show that several effects considered nuclear effects are not nuclear in the sense that they do not only occur in nucleus-nucleus and hadron-nucleus collisions but, as well, they are present in hadron-hadron (proton-proton) collisions. The matter creation mechanism in hh, hA and AA collisions is always the same. The pT suppression of particles produced in large multiplicity events compared to low multiplicity events, the elliptic flow and the Cronin effect are predicted to occur in pp collisions at LHC energies as a consequence of the obtained high density partonic medium.

description: BACKGROUND: Immature B lymphocytes and certain B cell lymphomas undergo apoptotic cell death following activation of the B cell antigen receptor (BCR) signal transduction pathway. Several biochemical changes occur in response to BCR engagement, including activation of the Syk tyrosine kinase. Although Syk activation appears to be necessary for some downstream biochemical and cellular responses, the signaling events that precede Syk activation remain ill defined. In addition, the requirements for complete activation of the Syk-dependent signaling step remain to be elucidated. RESULTS: A mutant form of Syk carrying a combination of a K395A substitution in the kinase domain and substitutions of three phenylalanines (3F) for the three C-terminal tyrosines was expressed in a murine B cell lymphoma cell line, BCL1.3B3 to interfere with normal Syk regulation as a means to examine the Syk activation step in BCR signaling. Introduction of this kinase-inactive mutant led to the constitutive activation of the endogenous wildtype Syk enzyme in the absence of receptor engagement through a 'dominant-positive' effect. Under these conditions, Syk kinase activation occurred in the absence of phosphorylation on Syk tyrosine residues. Although Syk appears to be required for BCR-induced apoptosis in several systems, no increase in spontaneous cell death was observed in these cells. Surprisingly, although the endogenous Syk kinase was enzymatically active, no enhancement in the phosphorylation of cytoplasmic proteins, including phospholipase Cgamma2 (PLCgamma2), a direct Syk target, was observed. CONCLUSION: These data indicate that activation of Syk kinase enzymatic activity is insufficient for Syk-dependent signal transduction. This observation suggests that other events are required for efficient signaling. We speculate that localization of the active enzyme to a receptor complex specifically assembled for signal transduction may be the missing event.

description: Ah, Wilderness! is Eugene O’Neill’s only comedy. The story takes place over the 4th of July weekend and revolves around Richard Miller, a misunderstood teen who rebels against 1906 society with suggestive poetry and declarations of communism. When his girlfriend, Muriel, spurns him at the behest of her father, his antics take a darker turn and lead him to a night of drinking, prostitutes and fist fights. However, all ends well as the two lovers reunite and Richard is surrounded by the love and compassion of his family. Ah, Wilderness! was produced at the Old Lyric theatre in the winter of 2014 and was directed by guest director, Paul Barnes. Shawn Fisher designed the set, Bruce Duerden designed sound, and Steven Piechocki designed lights. My advisor for this project was Dennis Hassan, and Louella Powell served as a mentor. I was given a budget of two-thousand dollars and roughly two and a-half months from the first concept meeting to opening night for the project. While some of the costume pieces were rented, many—especially the women’s—were constructed for the show.

description: Internet of Things (IoT) applications have opened up numerous possibilities to improve our lives. Most of the remote devices, part of the IoT network, such as smartphones, data loggers and wireless sensors are battery powered. It is vital to collect battery measurement data (Voltage or State-of-Charge (SOC)) from these remote devices. Presence of noise in these measurements restricts effective utilization of this dataset. This paper presents the application of Unscented Kalman Filter (UKF) to mitigate measurement noise in smartphone dataset. The simplicity of this technique makes it a constructive approach for noise removal. The datasets obtained after noise removal could be used to improve data-driven time series forecasting models which aid to accurately estimate critical battery parameters such as SOC. UKF was tested on noisy charge and discharge dataset of a smartphone. An overall Mean Squared Error (MSE) of 0.0017 and 0.0010 was obtained for Voltage charge and discharge measurements. MSE for SOC charge and discharge data measurements were 0.0018 and 0.0010 respectively.
