A multiwavelength study of 170 micron selected sources
Creators: name: Sajina, Anna
Publisher: name: University of British Columbia
Year: 2009

description: We present results from sub-mm observations of sources selected from the ISO FIRBACK (Far IR BACKground) survey, along with UKIRT near-IR imaging of a sub-sample. This gives valuable insight to the brightest 10% of galaxies which contribute to the Cosmic Infrared Background (CIB). We estimate the photometric redshifts and luminosities of these sources by fitting their Spectral Energy Distributions (SEDs). The data appear to show a bimodal galaxy distribution, with normal star-forming galaxies at z ≃ 0, and the z ~ 0.4-0.9 tail of a much more luminous population. These are similar to the ultraluminous infrared galaxies which are found to evolve rapidly with redshift in other surveys. We are biased away from much higher redshift objects by the detectability threshold of FIRBACK. Nevertheless, the handful of z ~ 0.5 sources which we identify are likely to be the low-2 counterparts of the typically higher-2 sources found in blank field sub-mm observations. The sources we identify here have the virtue of being relatively easy to study in the optical. Hence their detailed investigation could help elucidate the nature of the sub-mm bright galaxies.

description: The John von Neumann Institute for Computing (NIC) at the Research Centre Juelich, Germany, is one of the leading supercomputing centres in Europe. Founded as a national centre in the mid-eighties it now provides more and more resources to European scientists. This happens within EU-funded projects (I3HP, DEISA) or Europe-wide scientific collaborations. Beyond these activities NIC started an initiative towards the new EU member states in summer 2004. Outstanding research groups are offered to exploit the supercomputers at NIC to accelerate their investigations on leading-edge technology. The article gives an overview of the organisational structure of NIC, its current supercomputer systems, and its user support. Transnational Access (TA) within I3HP is described as well as access by the initiative for new EU member states. The volume of these offers and the procedure of how to apply for supercomputer resources is introduced in detail.

description: The ability of the former voluntary price reporting system to generate market transparency in U.S. livestock markets was called into question by producer groups and academic research prior to the new federal system of mandatory price reporting being implemented. The market transparency issue is investigated by comparing price data collected from the former AMS voluntary price reporting systems to mandatory price reporting data for live slaughter steers collected by the State of South Dakota before the advent of the new federal system. The relationship between a set of public price report series and the South Dakota mandatory price series is analyzed using cointegration techniques. The empirical findings indicate a strong long-run and short-run integrated relationship between the mandatory price series and a majority of the selected public price reports. We conclude that in the cash market for live steers in South Dakota, the former voluntary price reporting system did foster market transparency and aided in the price discovery process.

description: Among the reactions involved in the production and destruction of deuterium during Big Bang Nucleosynthesis, the deuterium-burning D(p,gamma)3He reaction has the largest uncertainty and limits the precision of theoretical estimates of primordial deuterium abundance. Here we report the results of a careful commissioning of the experimental setup used to measure the cross-section of the D(p,gamma)3He reaction at the Laboratory for Underground Nuclear Astrophysics of the Gran Sasso Laboratory (Italy). The commissioning was aimed at minimising all sources of systematic uncertainty in the measured cross sections. The overall systematic error achieved (< 3 %) will enable improved predictions of BBN deuterium abundance.

We review the theory and phenomenology of reheating and preheating after inflation providing a unified discussion of both the gravitational and nongravitational features of multi-field inflation. In addition we cover inflation in theories with extra dimensions and models such as the curvaton scenario and modulated reheating which provide alternative ways of generating large-scale density perturbations. Finally we discuss the interesting observational implications that can result from adiabatic-isocurvature correlations and non-Gaussianity.

description: We present results of a high angular resolution survey of massive OB stars in the Cygnus OB2 association that we conducted with the NIRI camera and ALTAIR adaptive optics system of the Gemini North telescope. We observed 74 O- and early B-type stars in Cyg OB2 in the $JHK$ infrared bands in order to detect binary and multiple companions. The observations are sensitive to equal-brightness pairs at separations as small as 0.08 \arcsec, and progressively fainter companions are detectable out to $Δ$ K = 9 mag at a separation of 2 arcsec. This faint contrast limit due to readnoise continues out to 10 arcsec near the edge of the detector. We assigned a simple probability of chance alignment to each companion based upon its separation and magnitude difference from the central target star and upon areal star counts for the general star field of Cyg OB2. Companion stars with a field membership probability of less than 1% are assumed to be physical companions. This assessment indicates that 47% of the targets have at least one resolved companion that is probably gravitationally bound. Including known spectroscopic binaries, our sample includes 27 binary, 12 triple, and 9 systems with four or more components. These results confirm studies of high mass stars in other environments that find that massive stars are born with a high multiplicity fraction. The results are important for the placement of the stars in the H-R diagram, the interpretation of their spectroscopic analyses, and for future mass determinations through measurement of orbital motion.

The study is a three-dimensional simulation of the Gross-Pitaevskii equation with a phenomenological dissipation term. The simulations reveal previously unknown dynamical features of the vortex nucleation process, in which the condensate undergoes a strongly turbulent stage and the penetrating vortex lines vibrate rapidly. The vibrations arise from spontaneous excitation of Kelvin waves on the proto-vortices during a surface wave instability, caused by an inhomogeneity of the condensate density along the elongated axial direction.

description: The ability of the former federal voluntary price reporting system to facilitate market efficiency in the cash markets for U.S. livestock was questioned by producer groups and academic researchers prior to implementation of federal mandatory price reporting regulations. In the cash market for slaughter cattle, concerns raised in the literature centered on the effect of thinning cash markets and strategic price reporting behavior on the robustness of voluntary cash price reports issued by the USDA-Agricultural Marketing Services. A theoretical framework is developed describing the interregional spatial linkages between cash markets and price reporting regimes (mandatory versus voluntary). Data from South Dakota and Nebraska cash markets for live cattle are used to test if the conditions necessary for interregional price transparency did exist prior to implementation of federal price reporting regulations. A set of testable hypotheses, based on the theoretical framework, is developed to test if the concerns raised in the literature about the voluntary price reporting system can be empiracally verified. The empirical results do not support the literature's proposition that the voluntary price reporting system for live cattle failed to provide timely and accurate market price information to the cash market prior to the implementation of the federal mandatory price reporting system in South Dakota and Nebraska. Furthermore, empirical evidence does not support the suppostion that a thinning cash market or strategic price reporting had a significant negative effect on the AMS voluntary price reporting system's accuracy or timely transmission of price information. Therefore, we conclude that the AMS voluntary price reporting system provided price transparency for South Dakota and Nebraska producers selling in the cash market and contributed to the price discovery process.
Langevin Simulation of the Chirally Decomposed Sine-Gordon Model

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: A large class of quantum and statistical field theoretical models, encompassing relevant condensed matter and non-abelian gauge systems, are defined in terms of complex actions. As the ordinary Monte-Carlo methods are useless in dealing with these models, alternative computational strategies have been proposed along the years. The Langevin technique, in particular, is known to be frequently plagued with difficulties such as strong numerical instabilities or subtle ergodic behavior. Regarding the chirally decomposed version of the sine-Gordon model as a prototypical case for the failure of the Langevin approach, we devise a truncation prescription in the stochastic differential equations which yields numerical stability and is assumed not to spoil the Berezinskii-Kosterlitz-Thouless transition. This conjecture is supported by a finite size scaling analysis, whereby a massive phase ending at a line of critical points is clearly observed for the truncated stochastic model.

description: We report high-fidelity state readout of a trapped ion qubit using a trap-integrated photon detector. We determine the hyperfine qubit state of a single $^9$Be$^+$ ion held in a surface-electrode rf ion trap by counting state-dependent ion fluorescence photons with a superconducting nanowire single-photon detector (SNSPD) fabricated into the trap structure. The average readout fidelity is 0.9991(1), with a mean readout duration of 46 $μ$s, and is limited by the polarization impurity of the readout laser beam and by off-resonant optical pumping. Because there are no intervening optical elements between the ion and the detector, we can use the ion fluorescence as a self-calibrated photon source to determine the detector quantum efficiency and its dependence on photon incidence angle and polarization.

description: In this work, we study the weak gravitational lensing in the background of Kerr-Newman black hole with quintessential dark energy. Initially, we compute the deflection angle of light by charged black hole with quintessential dark energy by utilizing the Gauss-Bnnet theorem. Firstly, we suppose the light rays on the equatorial plane in the axisymmetric spacetime. In doing so, we first find the corresponding optical metrics and then calculate the Gaussian optical curvature to utilize in Gauss-Bonnet theorem. Consequently, we calculate the deflection angle of light for rotating charged black hole with quintessence. Additionally, we also find the deflection angle of light for Kerr-Newman black hole with quintessential dark energy. In order to verify our results, we derive deflection angle by using null geodesic equations which reduces to the deflection angle of Kerr solution with the reduction of specific parameters. Furthermore, we analyze the graphical behavior of deflection angle $Θ$ w.r.t to impact parameter $b$. Our graphical analysis retrieves various results regarding to the deflection angle by the Kerr-Newman black hole with quintessential dark energy.

description: During the 2002 drought, farm sector economic factors were monitored to assess the likely statewide economic impacts. Timely moisture during the spring of 2003 resulted in a sizeable wheat harvest relative to recent years. Prices in the fall of 2003 resulted in a sizeable wheat harvest relative to recent years. Prices in the fall of 2003 have also been significantly higher for cattle and soybeans compared to prices in recent years. As a result, there have been inquiries as to the extent of economic recovery in the farm sector of South Dakota. The purpose of this paper is to outline the estimation procedure used to assess the drought in 2002, validate the extent of the impact, and discuss potential mitigating effects observed during 2003. The results suggest the direct costs to the farm sector in 2002 can best be described using a range of $650-800 million. The improved market conditions in 2003 would offset a portion of those losses at the state level. While the offset estimate is $477 million, a range of $375-550 million would better encompass the scope of the impact. Finally, while the aggregate farm sector will benefit in 2003, winter wheat and cow-calf producers most adversely affected by the drought will likely need additional time to recover.

description: The theorem known from Pauli equation about operators that anticommute with Dirac's $K$-operator is generalized to the Dirac equation. By means of this theorem the operator is constructed which governs the hidden symmetry in relativistic Coulomb problem (Dirac equation). It is proved that this operator coincides with the familiar Johnson-Lippmann one and is intimately connected to the famous Laplace-Runge-Lenz (LRL) vector. Our derivation is very simple and informative. It does not require a longtime and tedious calculations, as is offten underlined in most papers.

description: Weekly grid premium and discount price data for fed cattle have been collected over a 26 month period. The grid price data are combined with carcass data (2590 South Dakota slaughter steers) in order to investigate the variability in the price differential per cwt. when marketing fed cattle on a grid versus selling cattle at an average price (dressed weight). A three-stage recursive information structure is postulated. The theoretical model describes how the price differential is affected by changes in packer determined gird premiums and discounts on a weekly basis. The three-stage recursive model is then estimated using ordinary least squares. The results of the empirical analysis indicate that among all grid premiums and discounts, it is the choice/select discount playing the dominant role in determining weekly changes in the price differential.

description: Cow/calf producers operating in the Dakotas were surveyed on their price discovery strategies, marketing channel preferences, and their perceptions of how regime change in the public price reporting system for fed cattle affected the beef industry in general and the cow/calf industry in particular. Survey results indicate cow/calf producers consider local institutions (auction barns etc.) to be more reliable for price discovery and marketing their feeder and stocker cattle than regional or national institutions (futures market etc.). Consistent with this view, producers perceive that the current public price reporting system is less reliable than local market sources when making individual marketing decisions. However, Dakota cow/calf producers perceive livestock mandatory price reporting as benefiting the beef industry in general.

description: In this paper, a mode selection network (ModeNet) is proposed to enhance deep learning-based video compression. Inspired by traditional video coding, ModeNet purpose is to enable competition among several coding modes. The proposed ModeNet learns and conveys a pixel-wise partitioning of the frame, used to assign each pixel to the most suited coding mode. ModeNet is trained alongside the different coding modes to minimize a rate-distortion cost. It is a flexible component which can be generalized to other systems to allow competition between different coding tools. Mod-eNet interest is studied on a P-frame coding task, where it is used to design a method for coding a frame given its prediction. ModeNet-based systems achieve compelling performance when evaluated under the Challenge on Learned Image Compression 2020 (CLIC20) P-frame coding track conditions.

description: Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids. In particular, UV radiation between 200-300 nm becomes energetically very damaging to most of the terrestrial biological systems. On the other hand, UV radiation is usually considered one of the most important energy source on the primitive Earth for the synthesis of many biochemical compounds and, therefore, essential for several biogenesis processes. In this work, we use these properties of the UV radiation to define the bounderies of an ultraviolet habitable zone. We also analyze the evolution of the UV habitable zone during the main sequence stage of the star. We apply these criteria to study the UV habitable zone for those extrasolar planetary systems that were observed by the International Ultraviolet Explorer (IUE). We analyze the possibility that extrasolar planets and moons could be suitable for life, according to the UV constrains presented in this work and other accepted criteria of habitability (liquid water, orbital stability, etc.).

In these quantum algorithms, one can use any arbitrarily mixed state as the auxiliary qubits, and furthermore can recover the state of the auxiliary qubits to the original one after completing the computations. Since the recovered state can be employed in any other computations, we obtain that a single preparation of the auxiliary qubits in an arbitrarily mixed state is sufficient to implement the iterative procedure in the Simon algorithm or the period-finding algorithm.

description: Membrane tubes (spicules) arise in cells, or artificial membranes, in the nonlinear deformation regime due to, e.g. the growth of microtubules, actin filaments or sickle hemoglobin fibers towards a membrane. We calculate the axial force exerted by the cylindrical membrane tube, and its average radius, by taking into account steric interactions between the fluctuating membrane and the enclosed rod. The force required to confine a fluctuating membrane near the surface of the enclosed rod diverges as the separation approaches zero. This results in a smooth crossover of the axial force between a square root and a linear dependence on the membrane tension as the tension increases and the tube radius shrinks. This crossover can occur at the most physiologically relevant membrane tensions. Our work may be important in (i) interpreting experiments in which axial force is related to the tube radius or membrane tension (ii) dynamical theories for biopolymer growth in narrow tubes where these fluctuation effects control the tube radius.

title: A Comparative Analysis of Air-To-Ground Engagement Outcomes in the Joint Warfare System (JWARS) and the JWARS-Joint Semi-Automated Forces Federation

description: Multi-resolution modeling is the process by which a single model is created by connecting multiple individual models to describe phenomena at different levels of resolution [l]. "When we change resolutions, replacing a detailed model by a more aggregate one, we must ask whether results are 'consistent'" [2].

There are many methods of determining if the results of two simulations are 'consistent'. However, they are very entailed and require a detailed understanding of the individual models including their functionality, algorithms, and inner workings. A straight forward and rapid way of assessing potential inconsistencies is through a statistical comparison of the model outputs.

Three scenarios were executed in OSD JWARS, JWARS as released by the Office of the Secretary of Defense; FED JWARS, the modified version of JWARS utilized in the federation; and the Lynx federation. Using statistical analysis, equivalency of the air-to-ground (A2G) engagement results was tested using the Bonferroni approach to multiple comparisons.

This comparative analysis confirms there is no statistically significant difference in the A2G engagement results of OSD JWARS and FED JWARS. However, the analysis does show there is a statistically significant difference in the A2G engagement results of OSD JWARS and the Lynx federation.

description: We study the Kondo effect in a quantum dot coupled to half-metallic ferromagnetic electrodes in the regime of strong on-dot correlations. Using the equation of motion technique for nonequilibrium Green functions in the slave boson representation we show that the Kondo effect is not completely suppressed for anti-parallel leads magnetization. In the parallel configuration there is no Kondo effect but there is an effect associated with elastic cotunneling which in turn leads to similar behavior of the local (on-dot) density of states (LDOS) as the usual Kondo effect. Namely, the LDOS shows the temperature dependent resonance at the Fermi energy which splits with the bias voltage and the magnetic field. Moreover, unlike for non-magnetic or not fully polarized ferromagnetic leads the only minority spin electrons can form such resonance in the density of states. However, this resonance cannot be observed directly in the transport measurements and we give some clues how to identify the effect in such systems.

description: Within the framework of R-parity violating minimal supergravity model, at least three relatively large lepton-number violating $ł'$ type trilinear couplings at the GUT scale, not directly related to neutrino physics, can naturally generate via renormalization group (RG) evolution and/or CKM rotation the highly suppressed bilinear and trilinear parameters at the weak scale required to explain the neutrino oscillation data. The structure of the RG equations and the CKM matrix restrict the choices of the three input couplings to only eight possible combinations, each with its own distinctive experimental signature. The relatively large input couplings may lead to spectacular low energy signatures like rare weak decays of the $τ$ lepton and K mesons, direct lepton number violating decays of several sparticles, and unconventional decay modes (and reduced lifetime) of the lightest neutralino, assumed to be the lightest supersymmetric particle (LSP), all with sizable branching ratios. Several low background signals at the Tevatron and LHC have been suggested and their sizes are estimated to be at the observable level. From the particle content of the signal and the relative rate of different final states the input couplings at the GUT scale, i.e., the origin of neutrino masses and mixing angles, can be identified.

description: We consider the N-site U_{q}(gl(N)) integrable spin chain with periodic and open diagonal soliton-preserving boundary conditions. By employing analytical Bethe ansatz techniques we are able to determine the spectrum and the corresponding Bethe ansatz equations for the general case, where each site of the spin chain is associated to any representation of U_{q}(gl(N)). In the case of open spin chain, we study finite dimensional representations of the quantum reflection algebra, and prove in full generality that the pseudo-vacuum is a highest weight of the monodromy matrix. For these two types of spin chain, we study the (generalized) "algebraic" fusion procedures, which amount to construct the quantum contraction and the Sklyanin determinant for the affine U_{q}(gl(N)) and quantum reflection algebras. We also determine the symmetry algebra of these two types of spin chains, including general K and K^+ diagonal matrices for the open case. The case of open spin chains with soliton non-preserving boundary conditions is also presented in the framework of quantum twisted Yangians. The symmetry algebra of this spin chains is studied. We also give an exhaustive classification of the invertible matricial solutions to the corresponding reflection equation.

description: We give an overview on several recent topics of colossal magnetoresistive manganites in both experiments and theories, focusing on the effect of quenched disorder. The disorder is intrinsically involved since the compounds are solid solutions, and its importance has been pointed out in several experiments of transport and magnetic properties. Recent progress in the experimental control of the strength of disorder is also reviewed. Theoretically, the effect of the disorder has been explored within the framework of the double-exchange mechanism. Several efforts to understand the phase diagram and the electronic properties are reviewed. We also briefly discuss a recent topic on the effect of disorder on competing phases and the origin of colossal magnetoresistance.

description: We introduce a method for finding general solutions of third-order nonlinear differential equations by extending the modified Prelle-Singer method. We describe a procedure to deduce all the integrals of motion associated with the given equation so that the general solution follows straightforwardly from these integrals. The method is illustrated with several examples. Further, we propose a powerful method of identifying linearizing transformations. The proposed method not only unifies all the known linearizing transformations systematically but also introduces a new and generalized linearizing transformation (GLT). In addition to the above, we provide an algorithm to invert the nonlocal linearizing transformation. Through this procedure the general solution for the original nonlinear equation can be obtained from the solution of the linear ordinary differential equation.

Galaxy classification in the UBC/NASA multi-narrowband survey

description: The main goals of this thesis are to classify, catalog and extract a redshift distribution of galaxies in the UBC/NASA Multi-Narrowband Survey (UNMS), conducted at the NASA Orbital Debris Observatory (NODO). We aim to classify sources using a maximum of 39 photometric bands for any source observed. Two independent classification schemes were implemented and compared. One used the photometric information from all the filters available (X² fitting routine) and the other employed a neural network, which based classification on isophotal shape parameters as input (SExtractor). The classification efficiency of galaxies, based on independent confirmations were 80% and 90% for the X² routine and SExtractor stellarity index respectively, even though the comparison between the two methods was poor. The fitted redshifts were compared with spectroscopically determined redshifts from the NASA/IPAC Extra-Galactic Database (NED) for 19 galaxies. More than half of the sources had seriously discrepant photometric redshifts. The spectral energy distributions (SEDs) of the galaxies with redshifts that did match showed a smooth flux distribution (low noise) that contained 1 or 2 emission features. Spectra that showed a somewhat scattered distribution of flux points resulted in uncertain redshift estimates. Failure of the photometric redshift estimation technique prevented us from pursuing more detailed statistical analyses, such as the galaxy luminosity function. We discuss possible interpretations for the apparent photometric/spectroscopic redshift discrepancy.

description: The effects of the propagation of particles which have a finite life-time and an according broad distribution in their mass spectrum are discussed in the context of a transport descriptions. In the first part some example cases of mesonic modes in nuclear matter at finite densities and temperatures are presented. These equilibrium calculations illustrate the dynamical range of spectral distributions to be adequately covered by non-equilibrium description of the dynamics of two nuclei colliding at high energies. The second part addresses the problem of transport descriptions which properly account for the damping width of the particles. A systematic and general gradient approximation is presented in the form of diagrammatic rules which permit to derive a self-consistent transport scheme from the Kadanoff--Baym equation. The scheme is conserving and thermodynamically consistent provided the self-energies are obtained within the Phi-derivable two-particle irreducible (2PI) method of Baym. The merits, the limitations and partial cures of the limitations of this transport scheme are discussed in detail.
