Bulge-Disk Decompositions and Structural Bimodality of Ursa Major Cluster Spiral Galaxies

description: We present bulge and disk (B/D) decompositions of existing K'-band surface brightness profiles for 65 Ursa Major cluster spiral galaxies. This improves upon the disk-only fits of Tully et al. (1996). The 1996 disk fits were used by Tully & Verheijen (1997) for their discovery of the bimodality of structural parameters in the UMa cluster galaxies. It is shown that our new 1D B/D decompositions yield disk structural parameters that differ only slightly from the basic fits of Tully et al. and evidence for structural bimodality of UMa galaxies is maintained. Our B/D software for the decomposition of 1D surface brightness profiles of galaxies uses a non-linear minimization scheme to recover the best fitting Sersic bulge and exponential disk while accounting for the possible presence of a compact nucleus and spiral arms and for the effects of seeing and disk truncations. In agreement with Tully & Verheijen, we find that the distribution of near-infrared disk central surface brightnesses is bimodal with an F-test confidence of 80%. There is also strong evidence for a local minimum in the luminosity function at M_K' ~ -22. A connection between the brightness bimodality and a dynamical bimodality, based on new HI line widths, is identified. The B/D parameters are presented in an Appendix.

description: Influence of the self-phase modulation of quantum light on the induced resonant excitation of a semiconductor quantum dot is studied analytically in the case of the Kerr-nonlinearity of the medium. The phase nonlinearity is found to result actually in a resonance detuning specific for each field photon number state. This effect is shown to provide significant decrease of the excitation efficiency accompanied at the same time by more regular excitation dynamics obtained even for initial squeezed vacuum field state. The enhancement of entanglement between semiconductor and field subsystems with growing non-linearity is demonstrated. As a result, the formation of different types of non-Gaussian field states is found with features being analyzed in details.

Elliptic flow as a function of transverse momentum is reported for different collision centralities for charged hadrons and strangeness containing hadrons $K_{S}^{0}$, $Λ$, $Ξ$, $ϕ$ in the midrapidity region $|eta|<1.0$. Significant reduction in systematic uncertainty of the measurement due to non-flow effects has been achieved by correlating particles at midrapidity, $|η|<1.0$, with those at forward rapidity, $2.5

description: As a future music educator, I have learned how to teach students through various courses and instruction. During the last semester of my undergraduate, I am required to student teach. This gives me an opportunity to apply everything I’ve learned to see if it really works, and what my particular teaching style and philosophy is. At Sky View High School, I had the opportunity to teach the Sophomore Concert Band. For my thesis project, I decided to arrange a piece just for them – to rehearse with them and to score it to the strengths of the ensemble. Since I had previously done a contract with a traditional work entitled “The Three Ravens,” I decided this would be the perfect fit for my arrangement. The end product would be a two to three minute piece of music that would enhance the learning experience for my students.

title: ﻿Ultrasonic Analysis of Breast Tissue for Pathology Classification
Creators: name: Sorensen, Kristina Marie
Publisher: name: Utah State University
Year: 2012

description: Real time measurements may assist surgeons in obtaining negative or cancer free margins during lumpectomy to eliminate invasive re-excision. Previous findings show that high-frequency ultrasound can differentiate between a range of breast pathologies in surgical specimens. Two parameters, peak density and second-order spectral slope, are sensitive to histopathology. Our objective was to determine the mechanism linking high-frequency ultrasound to histology. The hypothesis is that ultrasound sensitivity is a function of the microscopic heterogeneity (and thus histology) of the tissue. Ultrasonic results from breast specimens were used to construct a multivariate analysis of the parameters that permitted differentiation of normal, adipose, benign, and malignant breast pathologies.

title: Observational Research in a Marketing Classroom: A Guidebook
Creators: name: Winterton, Kristen
Publisher: name: Utah State University
Year: 2012

description: Qualitative research plays an integral part in marketing research (Denzin and Lincoln, 1998). In fact, a search of the website for the American Marketing Association for the term “qualitative research” reveals literally hundreds of documents (white papers, case studies, etc) discussing methods of conducting observational research, examples of observational research studies, and the importance of observational research in marketing. Interestingly, though qualitative methods are used frequently by practitioners, they receive very limited attention in marketing textbooks. This seems particularly true of observation research, which is among the least expensive and easily conducted qualitative methods (Mann, 2003). The purpose of this research is to provide a substantive review of marketing texts to determine how observational research is being introduced to a student audience, and to confirm the existence of an education gap in the instruction, as well as to offer recommendations for improvement. Qualitative reviews performed in both practitioner and academic areas confirmed that treatment of observational research in the marketing classroom seem relatively less than its use in the field. To help address these differences, a guidebook is developed outlining the benefits, challenges, and methods of conducting elementary observational research techniques.

description: Recent studies have shown that both 21cm HI absorption and soft X-ray absorption serve as excellent tracers of the dense and dusty gas near the active nucleus of young radio galaxies, offering new insight into the physical nature of the circumnuclear medium. To date, a correlation between the column densities derived using these absorption processes has been observed within Compact Steep Spectrum (CSS) and Gigahertz-Peaked Spectrum (GPS) radio sources. While it is possible that this correlation exists within the broader radio population, many samples of radio galaxies make this difficult to test due to selection effects. This paper explores the possibility of a correlation in the broader radio population by analysing a historic sample of 168 radio sources compiled from the literature in such a way so as to minimise selection bias. From this historic sample we conclude that there is some evidence for a correlation between HI and soft X-ray absorption outside of peaked spectrum sources, but that the selection bias towards these sources makes further analysis difficult using current samples. We discuss this in the context of the SEAFOG project and how forthcoming data will change the landscape of future absorption studies.

description: Quasipatterns (two-dimensional patterns that are quasiperiodic in any spatial direction) remain one of the outstanding problems of pattern formation. As with problems involving quasiperiodicity, there is a small divisor problem. In this paper, we consider 8-fold, 10-fold, 12-fold, and higher order quasipattern solutions of the Swift-Hohenberg equation. We prove that a formal solution, given by a divergent series, may be used to build a smooth quasiperiodic function which is an approximate solution of the pattern-forming PDE up to an exponentially small error.

description: The final architecture of planetary systems depends on the extraction of angular momentum and mass-loss processes of the discs in which they form. Theoretical studies proposed that magnetized winds launched from the discs (MHD disc winds) could govern accretion and disc dispersal. In this work, we revisit the observed disc demographics in the framework of MHD disc winds, combining analytical solutions of disc evolution and a disc population synthesis approach. We show that MHD disc winds alone can account for both disc dispersal and accretion properties. The decline of disc fraction over time is reproduced by assuming that the initial accretion timescale (a generalization of the viscous timescale) varies from disc to disc and that the decline of the magnetic field strength is slower than that of the gas. The correlation between accretion rate and disc mass, and the dispersion of the data around the mean trend as observed in Lupus is then naturally reproduced. The model also accounts for the rapidity of the disc dispersal. This paves the way for planet formation models in the paradigm of wind-driven accretion.

description: Scalar boson stars and Dirac stars are solitonic solutions of the Einstein{Klein-Gordon and Einstein- Dirac classical equations, respectively. Despite the different bosonic vs: fermionic nature of the matter field, these solutions to the classical field equations have been shown to have qualitatively similar features [1]. In particular, for spinning stars the most fundamental configurations can be in both cases toroidal, unlike spinning Proca stars that are spheroidal [2]. In this paper we gauge the scalar and Dirac fields, by minimally coupling them to standard electromagnetism. We explore the impact of the gauge coupling on the resulting solutions. One of the most relevant difference concerns the gyromagnetic ratio, which for the scalar stars takes values around 1, whereas for Dirac stars takes values around 2.

The effects of inoculation, distraction and sensory deprivation on attitude change and counterarguing
Creators: name: Tetlock, Philip Eyrikson
Publisher: name: University of British Columbia
Year: 2010

description: There is impressively consistent empirical support for the hypotheses that distraction and sensory deprivation increase responsiveness to persuasive inputs. The primary purpose of the two experiments reported here was to investigate whether distraction and sensory deprivation also increase the persuasive impact of attacks on cultural truisms, and the manner in which prior provision of counterarguments in the form of a refutational inoculation message interacts with these treatments. The effects of the independent variables were assessed by dependent measures of four theoretically distinct but related aspects of the attitude change process: comprehension, message belief acceptance, attitude change and cognitive reactions r— to the persuasive message. A total of one hundred subjects served in the two experiments. In the first experiment, the effects of three levels of distraction (no distraction, low effort distraction, high effort distraction) and of the presence or absence of refutational inoculation were examined. Contrary to previous research, distraction had no effect on any of the dependent measures; refutational inoculation, consistent with previous research, reduced message belief acceptance, increased pro-truism attitudes and increased counterarguments against the message. In the second experiment, the effects of three levels of sensory deprivation (0, 1 hour, 23 hours) and of the presence or absence of refutational inoculation were examined. Again contrary to previous research, sensory deprivation had no effect on any of the dependent measures; consistent with previous research, refutational inoculation reduced message belief acceptance, increased pro-truism attitudes and increased counterargument production. The implications of these results for competing explanations of distraction and sensory deprivation effects were discussed. The cognitive dissonance interpretation of the effects of distraction and the information need interpretation of the effects of sensory deprivation appear unable to account for the failure of these manipulations to increase persuasion. These findings are more in accord with the counterargument disruption interpretation. In addition, the counterarguing process appears to represent an important aspect of the general effects of the refutational inoculation message. Further research, using the same procedures of the present study, but a non-cultural truism as the attitude topic, is required to test the counterargument disruption interpretation more rigorously.
title: Design and Optimization of a Thermal Capacitor
Creators: name: Nielson, Karen

Publisher: name: Utah State University
Year: 2013

description: Team Hot Stuff designed a thermal capacitor for Senior Design I at Utah State University. This thermal capacitor is intended for use in the food service industry as a low-cost alternative to chafers. Chafers are platters which use oil burners to keep food warm. The client for this thermal capacitor is Thermal Management Technologies (TMT), a company specializing in thermal science solutions whose mission is “to provide simple, practical thermal science solutions to a wide range of platforms including: Industry, Defense, and Space”1. The founder and president of TMT, Dr. J. Clair Batty, serves as a mentor for this project.
The project is broken down into tasks and split among the team members. Karen Nielson is team lead. As team lead, Karen’s responsibilities include overseeing and helping with all tasks, as well as ensuring that the team remains on task and on schedule. Brian Pincock is in charge of the team schedule and the thermal analysis. Brian is responsible for keeping track of task completions, updating the schedule and building and running various thermal models of the thermal capacitor. Ruby Kostur is the purchasing agent and is in charge of selection and purchasing of materials. Ruby’s responsibilities include researching, selecting, purchasing and budgeting parts and materials for the thermal capacitor. Jordan Cox is in charge of the design drawings and structural analysis. Jordan is responsible for constructing virtual models of the various parts of the thermal capacitor and analyzing the potential structural problems.
The team developed a list of requirements with the customer. These requirements are listed in Section 3 Statement of Problem. The team decided on the following design parameters:
Phase change material: Beeswax
Heat spreader: Aluminum honeycomb
Container material: Aluminum 6061
Insulation: Western Red Cedar
Bonding: Epoxy
Seal: O-ring
Fasteners: Stainless steel screws
To select these parameters the team performed thermal, structural, and materials analysis.
Brian Pincock oversaw thermal analysis. He consulted with professional engineers at TMT and professors at USU to decide on a correct modeling method.Using Star CCM to model the physics, Brian proved the final design would meet requirements. Jordan Cox performed structural analysis using FEMAP. His models confirmed that the final bolt pattern and O-ring seal would be safe and functional. Ruby Kostur used these results to select materials which maintained the budgetary constraints.

description: Despite the apparent cross-disciplinary interactions among scientific fields, a formal description of their evolution is lacking. Here we describe a novel approach to study the dynamics and evolution of scientific fields using a network-based analysis. We build an idea network consisting of American Physical Society Physics and Astronomy Classification Scheme (PACS) numbers as nodes representing scientific concepts. Two PACS numbers are linked if there exist publications that reference them simultaneously. We locate scientific fields using a community finding algorithm, and describe the time evolution of these fields over the course of 1985-2006. The communities we identify map to known scientific fields, and their age depends on their size and activity. We expect our approach to quantifying the evolution of ideas to be relevant for making predictions about the future of science and thus help to guide its development.

title: Deconstructing the Supernatural in Shakespeare's Macbeth
Creators: name: Marler, Britney
Publisher: name: Utah State University
Year: 2013

description: Of all Shakespeare's tragedies, Macbeth is by far the most supernaturally charged. The play opens with three witches who give Macbeth and Banquo a prediction that lays out the plot of the rest of the play. Macbeth sees a phantom dagger, hears voices, and is haunted by the ghost of his murdered comrade. The vast amount of supernatural events comes as no surprise considering that Shakespeare almost certainly wrote the play as a tribute to King James I, the British monarch whose belief in the power of witchcraft ran so deep that he led several witchhunts throughout Britain, in addition to writing Daemonologie, a text that argued for the reality of witches and the study of witchcraft's place in legitimate theological studies at the time. Led by King James, England treated supernatural phenomenon as a very real presence in the world at the time Shakespeare wrote Macbeth. While witches are perhaps the most ostentatious and the primary focus of King James's attention, they were by no means the only form the supernatural was said to take. Ghosts, visions and dreams, postmortem bleeding corpses, possession of devils, each had a place in Jacobean culture.

description: We have performed an extensive study of single-crystals of the magneto-electric NdFe$_3$($^{11}$BO$_3$)$_4$ by means of a combination of single-crystal neutron diffraction and spherical neutron polarimetry. Our investigation did not detect significant deviations at low temperatures from space group R32 concerning the chemical structure. With respect to magnetic ordering our combined results demonstrate that in the commensurate magnetic phase below T$_N$~30 K all three magnetic Fe moments and the magnetic Nd moment are aligned ferromagnetically in the basal hexagonal plane but align antiferromagnetically between adjacent planes. The phase transition to the low-temperature incommensurate magnetic structure observed at T$_{IC}$~13.5 K appears to be continuous. By means of polarized neutron studies it could be shown that in the incommensurate magnetic phase the magnetic structure of NdFe$_3$($^{11}$BO$_3$)$_4$ is transformed into a long-period antiferromagnetic helix with single chirality. Close to the commensurate-incommensurate phase transition third-order harmonics were observed which in addition indicate the formation of magnetic solitons.

description: The aim of our work is to study the effect of geometry variation on nucleation times and to address its role in the context of eukaryotic chemotaxis (i.e. the process which allows cells to identify and follow a gradient of chemical attractant). As a first step in this direction we study the nucleation dynamics of the 2d Ising model defined on a cylindrical lattice whose radius changes as a function of time. Geometry variation is obtained by changing the relative value of the couplings between spins in the compactified (vertical) direction with respect to the horizontal one. This allows us to keep the lattice size unchanged and study in a single simulation the values of the compactification radius which change in time. We show, both with theoretical arguments and numerical simulations that squeezing the geometry allows the system to speed up nucleation times even in presence of a very small energy gap between the stable and the metastable states. We then address the implications of our analysis for directional chemotaxis. The initial steps of chemotaxis can be modelled as a nucleation process occurring on the cell membrane as a consequence of the external chemical gradient (which plays the role of energy gap between the stable and metastable phases). In nature most of the cells modify their geometry by extending quasi-onedimensional protrusions (filopodia) so as to enhance their sensitivity to chemoattractant. Our results show that this geometry variation has indeed the effect of greatly decreasing the timescale of the nucleation process even in presence of very small amounts of chemoattractants.

Two types of spin-orbit interaction, pertinent to the graphene lattice, are taken into account - the intrinsic and Rashba terms. Assuming perfect crystal lattice, we calculate the topological contribution to spin Hall conductivity. When both interactions are present, their interplay is shown to lead to some peculiarities in the dependence of spin Hall conductivity on the Fermi level.

description: We report preliminary results on the analysis of the continuum and H$β$ light curves of the type-1 active galactic nucleus (AGN) NGC 5548. We notice a clear signature of shallowing in the trend between the H$β$ and the continuum luminosities. We attempt the recovery of this observed H$β$ emission trend as a response to large continuum flux increase using CLOUDY photoionization simulations. We explore a wide range in the physical parameters space for modelling the H$β$ emission from the broad-line region (BLR) appropriate for this source. We employ a constant density, single cloud model approach in this study and successfully recover the observed shallowing of the H$β$ emission with respect to the rising AGN continuum. With our modelling, we are able to provide constraints on the local BLR cloud density and recover the BLR distances (from the continuum source) consistent with the H$β$ reverberation mapping estimates. We further discuss the implications of the BLR covering factor and their sizes on recovering the observed trend.

This paper proposes a novel user allocation scheme applicable to the heterogeneous radio access networks supplied with renewable energy sources. Presented results proved that high-energy efficiency can be accomplished by reallocating some traffic to the green wireless base station.

description: The amplitude of cosmological density fluctuations, sigma_8, has been studied and estimated by analysing many cosmological observations. The values of the estimates vary considerably between the various probes. However, different estimators probe the value of sigma_8 in different cosmological scales and do not take into account the nonlinear evolution of the parameter at late times. We show that estimates of the amplitude of cosmological density fluctuations derived from cosmic flows are systematically higher than those inferred at early epochs from the CMB because of nonlinear evolution at later times. We discuss the past and future evolution of linear and nonlinear perturbations, derive corrections to the value of sigma_8 and compare amplitudes after accounting for these differences.

The spatially resolved observations largely confirm SED-only based hypotheses on disk structure, yet also reveal degeneracies that may occur in such SED modeling. The properties of the dust on the disk surface show a strong radial dependence: the dust close to the central star has generally larger grain sizes and in particular a much higher crystallinity than the dust in more remote disk regions.

description: In a preceding Letter (Opt. Lett. 32, 554 (2007)) we have proposed complex continuous wavelet transforms (CCWTs) and found Laguerre--Gaussian mother wavelets family. In this work we present the inversion formula and Parsval theorem for CCWT by virtue of the entangled state representation, which makes the CCWT theory complete. A new orthogonal property of mother wavelet in parameter space is revealed.

description: IXPE scientific payload comprises of three telescopes, each composed of a mirror and a photoelectric polarimeter based on the Gas Pixel Detector design. The three focal plane detectors, together with the unit which interfaces them to the spacecraft, are named IXPE Instrument and they will be built and calibrated in Italy; in this proceeding, we will present how IXPE Instrument will be calibrated, both on-ground and in-flight. The Instrument Calibration Equipment is being finalized at INAF-IAPS in Rome (Italy) to produce both polarized and unpolarized radiation, with a precise knowledge of direction, position, energy and polarization state of the incident beam. In flight, a set of four calibration sources based on radioactive material and mounted on a filter and calibration wheel will allow for the periodic calibration of all of the three IXPE focal plane detectors independently. A highly polarized source and an unpolarized one will be used to monitor the response to polarization; the remaining two will be used to calibrate the gain through the entire lifetime of the mission.

description: We propose a model for a power-counting renormalizable field theory living in a fractal spacetime. The action is Lorentz covariant and equipped with a Stieltjes measure. The system flows, even in a classical sense, from an ultraviolet regime where spacetime has Hausdorff dimension 2 to an infrared limit coinciding with a standard $D$-dimensional field theory. We discuss the properties of a scalar field model at classical and quantum level. Classically, the field lives on a fractal which exchanges energy-momentum with the bulk of integer topological dimension D. Although an observer experiences dissipation, the total energy-momentum is conserved. The field spectrum is a continuum of massive modes. The gravitational sector and Einstein equations are discussed in detail, also on cosmological backgrounds. We find ultraviolet cosmological solutions and comment on their implications for the early universe.

description: Abstract: By this study, we aim to elaborate ``Pratical Process based on ICT``(Innovation)  for management of every waste produced in our environment in order to improve conditions of life. We have used some geolocalisation softwares, Internet connection and Microsoft Excell as technology to perform this work. Our interest was focused on hold housing wastes, pluvial and used liquid waste. Our mind was to manage waste produced in our environment in order to improve life in it. So, we did our study in a city called Soweto in Abidjan- Ivory Coast located in Africa. The general purpose of this study is Innovative.

Waste Management System (IWMS) consisting to collect, transport, dispose or/ recycle and control waste. According to these four subsystems developed, the focus of this study was on collection/production system of waste and control systems. For liquid waste, functional infrastructure network is ideal for collection/transportation of and have been done. For used waste, drainage or/with connection of toilet septic tank is the best according to simulation results. For solid waste, frequently collection of waste` has been chosen. Collection must be applied by installation of gabage in a relative architecture in the city, visdange of, transportation to discharge for treatment. We modeled the productions of waste according to our survey and shape a created system of production management for. The concept on control consisted to adapt frequency of collection in certain architecture of city with production of wastes.  At the end, test of this system management of waste has been made and the results were good depending of three conditions elaborated. 13 criteria have been defined: Length (m), Number of potholes (NoP); Number of discharges point for collected cumbersome waste (NoDP); Length of Irrigation Network to clean (LoIN); Number of septic tank to drain (NoFV); Total areas (m2) of potholes (TAoP); Total volumes (L) to drain (TVV); Total Volume of Drainage Point (T) to clean (TVoDP); Volume of used waste/Pluvial (HL) to clean (VoUW); Volumes (L) of cleaning water needed (VoCWN); Number of Crossroads ( NoC); Number of collection Point (NoCP), Number of empty areas (NoNA). Only 5 have been considered for simulation. With satisfaction obtained, we think that this system can be used in many fields.

Other studies will consist to perform 2 others systems (transportation, treatment recycle).

description: We compute the gravitational corrections to the running of couplings in a scalar-fermion system, using the Wilsonian approach. Our discussion is relevant for symmetric as well as for broken scalar phases. We find that the Yukawa and quartic scalar couplings become irrelevant at the Gaussian fixed point.

Dynamical Screening and Ferroelectric-type Excitonic Instability in Bilayer Graphene

description: Electron interactions in undoped bilayer graphene lead to instability of the gapless state, `which-layer' symmetry breaking, and energy gap opening at the Dirac point. In contrast to single layer graphene, the bilayer system exhibits instability even for arbitrarily weak interaction. A controlled theory of this instability for realistic dynamically screened Coulomb interactions is developed, with full acount of dynamically generated ultraviolet cutoff. This leads to an energy gap that scales as a power law of the interaction strength, making the excitonic instability readily observable.

description: We propose a high-contrast coronagraph for direct imaging of young Jupiter-like planets orbiting nearby bright stars. The coronagraph employs a step-transmission filter in which the intensity is apodized with a finite number of steps of identical transmission in each step. It should be installed on a large ground-based telescope equipped with state-of-the-art adaptive optics systems. In that case, contrast ratios around 10^-6 should be accessible within 0.1 arc seconds of the central star. In recent progress, a coronagraph with circular apodizing filter has been developing, which can be used for a ground-based telescope with central obstruction and spider structure. It is shown that ground-based direct imaging of Jupiter-like planets is promising with current technology.
