description: Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until recently, only seven were observed to pulse in gamma rays and these were all discovered at other wavelengths. The Fermi Large Area Telescope makes it possible to pinpoint neutron stars through their gamma-ray pulsations. We report the detection of 16 gamma-ray pulsars in blind frequency searches using the LAT. Most of these pulsars are coincident with previously unidentified gamma-ray sources, and many are associated with supernova remnants. Direct detection of gamma-ray pulsars enables studies of emission mechanisms, population statistics and the energetics of pulsar wind nebulae and supernova remnants.

description: The temporal evolution of the spatially periodic electroconvection (EC) patterns has been studied within the period of the driving ac voltage by monitoring the light intensity diffracted from the pattern. Measurements have been carried out on a variety of nematic systems, including those with negative dielectric and positive conductivity anisotropy, exhibiting "standard EC" (s-EC), those with both anisotropies negative exhibiting "non-standard EC" (ns-EC), as well as those with the two anisotropies positive. Theoretical predictions have been confirmed for stationary s-EC and ns-EC patterns. Transitions with Hopf bifurcation have also been studied. While traveling had no effect on the temporal evolution of dielectric s-EC, traveling conductive s-EC and ns-EC patterns exhibited a substantially altered temporal behavior with a dependence on the Hopf frequency. It has also been shown that in nematics with both anisotropies positive, the pattern develops and decays within an interval much shorter than the period, even at relatively large driving frequencies.

Using ASP with recent extensions for causal explanations

Subjects: subject: Artificial Intelligence (cs.AI)

description: We examine the practicality for a user of using Answer Set Programming (ASP) for representing logical formalisms. We choose as an example a formalism aiming at capturing causal explanations from causal information. We provide an implementation, showing the naturalness and relative efficiency of this translation job. We are interested in the ease for writing an ASP program, in accordance with the claimed ``declarative'' aspect of ASP. Limitations of the earlier systems (poor data structure and difficulty in reusing pieces of programs) made that in practice, the ``declarative aspect'' was more theoretical than practical. We show how recent improvements in working ASP systems facilitate a lot the translation, even if a few improvements could still be useful.

description: We present results from numerical simulations of the cooling-core cluster A2199 produced by the two-dimensional (2-D) resistive magnetohydrodynamics (MHD) code MACH2. In our simulations we explore the effect of anisotropic thermal conduction on the energy balance of the system. The results from idealized cases in 2-D axisymmetric geometry underscore the importance of the initial plasma density in ICM simulations, especially the near-core values since the radiation cooling rate is proportional to ${n_e}^2$. Heat conduction is found to be non-effective in preventing catastrophic cooling in this cluster. In addition we performed 2-D planar MHD simulations starting from initial conditions deliberately violating both thermal balance and hydrostatic equilibrium in the ICM, to assess contributions of the convective terms in the energy balance of the system against anisotropic thermal conduction. We find that in this case work done by the pressure on the plasma can dominate the early evolution of the internal energy over anisotropic thermal conduction in the presence of subsonic flows, thereby reducing the impact of the magnetic field. Deviations from hydrostatic equilibrium near the cluster core may be associated with transient activity of a central active galactic nucleus and/or remnant dynamical activity in the ICM and warrant further study in three dimensions.

description: We report results from a study of the HI content and stellar properties of nearby galaxies detected by the Arecibo Legacy Fast ALFA blind 21-cm line survey and the Sloan Digital Sky Survey in two declination strips covering a total area of 9 hr X 16 deg. Our analysis seeks to assemble a control sample of galaxies suitable for providing absolute measures of the HI content of gaseous objects. From a database of ~15,000 HI detections, we have assembled three samples of gas-rich galaxies expected to show little or no evidence of interaction with their surroundings that could provide adequate HI standards. The most reliable results are obtained with a sample of 5647 sources found in low density environments, as defined by a nearest neighbor approach. The other two samples contain several hundred relatively isolated galaxies each, as determined from standard isolation algorithms. We find that isolated objects are not particularly gas-rich compared to their low-density-environment counterparts, while they suffer from selection bias and span a smaller dynamic range. All this makes them less suitable for defining a reference for HI content. We have explored the optical morphology of gaseous galaxies in quiet environments finding that, within the volume surveyed, the vast majority of them display unequivocal late-type galaxy features. In contrast, bona fide gas-rich early-type systems account only for a negligible fraction of the 21-cm detections. We argue that HI emission provides the most reliable way to determine the morphological population to which a galaxy belongs. We have also observed that the color distribution of flux-limited samples of optically-selected field HI emitters does not vary significantly with increasing distance, while that of non-detections becomes notably redder. This result suggests that the colors and HI masses of gas-rich galaxies cannot be very closely related.

The spectrum is notable for its lack of a low ionization transient heavy element absorption system that is visible in the large majority of novae near maximum light.

CO₂-EOR

description: CO₂ enhanced oil recovery (CO₂-EOR) is a form of carbon storage that has the potential to minimize CO₂ emissions while also increasing energy output from newly recovered oil. Louisiana is the 5th largest emitter of energy-related CO₂ in the United States, with about 200 million metric tonnes of CO₂ emitted annually. Louisiana has over 20,000 oil and gas reservoirs and 287 CO₂ point sources. This study used a screening methodology at the reservoir level to identify appropriate CO₂-EOR candidate reservoirs in Louisiana and their CO₂-EOR reserve estimates. Also, an economic analysis of CO₂-EOR was carried out in this thesis, which included sensitivity and scenario analysis. In Louisiana, this study identified 217 reservoirs across 86 oil fields as potential CO₂-EOR candidates. According to the Louisiana assessment, the 217 candidate reservoirs have a total of 1.4 billion STB of OOIP and a 205 million STB incremental oil potential worth $12.3 billion. The CO₂ storage capacity of these reservoirs is projected to be 100 million metric tons. There are several other suitable candidate reservoirs in Louisiana that were not taken into account in this analysis. When combined with the reservoirs described in this thesis, the incremental oil recovered potential and CO₂ reservoir storage capacity will reach 1.5 billion STB and 2.6 billion metric tons, respectively. In Haynesville, Bayou Segnette, and Paradis, case studies were conducted for suitable CO₂-EOR candidate reservoirs. The sensitivity studies revealed that the net income and economic viability of a CO₂-EOR project are highly dependent on oil price, CO₂ cost, and tax policy. CO₂-EOR would benefit greatly from the high oil price, low CO₂ cost, and low tax policy. Given the current economic situation, the economic analysis indicates that operating successful CO₂-EOR projects would be difficult. However, the study also shows that CO₂-EOR projects can be made economically feasible by combining 1. tax reductions/exemptions in areas such as royalties, income tax, and severance tax. 2. negotiating lower CO₂ prices 3. Increase in tax credit for capturing facilities to lower CO₂ prices for storage parties

The surface of the bubble is described by a smooth magnetically charged solitonic brane whose asymptotic flux is precisely that responsible for stabilizing the 4d compactification. We describe several instances of bubble geometries for the various vacua occurring in a $6d$ Einstein-Maxwell theory namely, AdS_4 x S^2, R^{1,3} x S^2, and dS_4 x S^2. Unlike conventional solutions, the bubbles of nothing introduced here occur where a {\em two}-sphere compactification manifold homogeneously degenerates.

Charax can be distinguished not only from Roeboides, but from all other characid genera by the presence of a notch on the posteroventral portion of the cleithrum originating a posteriorly directed spiniform projection (Lucena, 1987: 68, figs. 15; 69, fig. 16). This uniquely derived synapomorphy used in combination with the following non-exclusive characters are useful for diagnosing Charax. 1 - Rhinosphenoid absent (Mattox & Toledo-Piza, 2012: 837, fig. 17A). 2 - Anterodorsal branch of laterosensory canal absent on infraorbital 6 (Mattox & Toledo-Piza, 2012: 841, fig. 19A). 3 - Jaws without external teeth. 4 - Humeral dark blotch present, inconspicuous in Charax stenopterus and closer to vertical through dorsal-fin origin than to posterior border of opercle in some species.

description: Quantum gases in optical lattices offer an opportunity to experimentally realize and explore condensed matter models in a clean, tunable system. We investigate the Bose-Hubbard model on a microscopic level using single atom-single lattice site imaging; our technique enables space- and time-resolved characterization of the number statistics across the superfluid-Mott insulator quantum phase transition. Site-resolved probing of fluctuations provides us with a sensitive local thermometer, allows us to identify microscopic heterostructures of low entropy Mott domains, and enables us to measure local quantum dynamics, revealing surprisingly fast transition timescales. Our results may serve as a benchmark for theoretical studies of quantum dynamics, and may guide the engineering of low entropy phases in a lattice.

description: The vast majority of optically identified active galactic nuclei (AGNs) in the local Universe reside in host galaxies with prominent bulges, supporting the hypothesis that black hole formation and growth is fundamentally connected to the build-up of galaxy bulges. However, recent mid-infrared spectroscopic studies with Spitzer of a sample of optically "normal" late-type galaxies reveal remarkably the presence of high-ionization [NeV] lines in several sources, providing strong evidence for AGNs in these galaxies. We present follow-up X-ray observations recently obtained with XMM-Newton of two such sources, the late-type optically normal galaxies NGC 3367 and NGC 4536. Both sources are detected in our observations. Detailed spectral analysis reveals that for both galaxies, the 2-10 keV emission is dominated by a power law with an X-ray luminosity in the 10^39 - 10^40 ergs s^-1 range, consistent with low luminosity AGNs. While there is a possibility that X-ray binaries account for some fraction of the observed X-ray luminosity, we argue that this fraction is negligible. These observations therefore add to the growing evidence that the fraction of late-type galaxies hosting AGNs is significantly underestimated using optical observations alone. A comparison of the mid-infrared [NeV] luminosity and the X-ray luminosities suggests the presence of an additional highly absorbed X-ray source in both galaxies, and that the black hole masses are in the range of 10^5 - 10^7 M_solar for NGC 3367 and 10^4 - 10^6 M_solar for NGC 4536.

description: We discovered evidence for a possible additional 0.75 R_Earth transiting planet in the NASA EPOXI observations of the known M dwarf exoplanetary system GJ 436. Based on an ephemeris determined from the EPOXI data, we predicted a transit event in an extant Spitzer Space Telescope 8 micron data set of this star. Our subsequent analysis of those Spitzer data confirmed the signal of the predicted depth and at the predicted time, but we found that the transit depth was dependent on the aperture used to perform the photometry. Based on these suggestive findings, we gathered new Warm Spitzer Observations of GJ 436 at 4.5 microns spanning a time of transit predicted from the EPOXI and Spitzer 8 micron candidate events. The 4.5 micron data permit us to rule out a transit at high confidence, and we conclude that the earlier candidate transit signals resulted from correlated noise in the EPOXI and Spitzer 8 micron observations. In the course of this investigation, we developed a novel method for correcting the intrapixel sensitivity variations of the 3.6 and 4.5 micron channels of the Infrared Array Camera (IRAC) instrument. We demonstrate the sensitivity of Warm Spitzer observations of M dwarfs to confirm sub-Earth sized planets. Our analysis will inform similar work that will be undertaken to use Warm Spitzer observations to confirm rocky planets discovered by the Kepler mission.

description: Conversational systems can be particularly effective in supporting complex information seeking scenarios with evolving information needs. Finding the right products on an e-commerce platform is one such scenario, where a conversational agent would need to be able to provide search capabilities over the item catalog, understand and make recommendations based on the user's preferences, and answer a range of questions related to items and their usage. Yet, existing conversational datasets do not fully support the idea of mixing different conversational goals (i.e., search, recommendation, and question answering) and instead focus on a single goal. To address this, we introduce MG-ShopDial: a dataset of conversations mixing different goals in the domain of e-commerce. Specifically, we make the following contributions. First, we develop a coached human-human data collection protocol where each dialogue participant is given a set of instructions, instead of a specific script or answers to choose from. Second, we implement a data collection tool to facilitate the collection of multi-goal conversations via a web chat interface, using the above protocol. Third, we create the MG-ShopDial collection, which contains 64 high-quality dialogues with a total of 2,196 utterances for e-commerce scenarios of varying complexity. The dataset is additionally annotated with both intents and goals on the utterance level. Finally, we present an analysis of this dataset and identify multi-goal conversational patterns.

description: Using inelastic neutron scattering, x-ray, neutron diffraction, and the first-principle calculation techniques, we show that the crystal structure of the two-dimensional quantum spin system (CuCl)LaNb$_2$O$_7$ is orthorhombic with $Pbam$ symmetry in which CuCl$_4$O$_2$ octahedra are tilted from their high symmetry positions and the Cu$^{2+} (s = 1/2)$ ions form a distorted square lattice. The dominant magnetic interactions are the fourth nearest neighbor antiferromagnetic interactions with a Cu-Cl--Cl-Cu exchange path, which lead to the formation of spin singlets. The two strongest interactions between the singlets are ferromagnetic, which makes (CuCl)LaNb$_2$O$_7$ the first system of ferromagnetically coupled Shastry-Sutherland quantum spin singlets.

description: When extracting the weak lensing shear signal, one may employ either locally normalized or globally normalized shear estimators. The former is the standard approach when estimating cluster masses, while the latter is the more common method among peak finding efforts. While both approaches have identical signal-to-noise in the weak lensing limit, it is possible that higher order corrections or systematics considerations make one estimator preferable over the other. In this paper, we consider the efficacy of both estimators within the context of stacked weak lensing mass estimation in the Dark Energy Survey (DES). We find the two estimators have nearly identical statistical precision, even after including higher order corrections, but that these corrections must be incorporated into the analysis to avoid observationally relevant biases in the recovered masses. We also demonstrate that finite bin-width effects may be significant if not properly accounted for, and that the two estimators exhibit different systematics, particularly with respect to contamination of the source catalog by foreground galaxies. Thus, the two estimators may be employed as a systematics cross-check of each other. Stacked weak lensing in the DES should allow for the mean mass of galaxy clusters to be calibrated to about 2% precision (statistical only), which can improve the figure of merit of the DES cluster abundance experiment by a factor of ~3 relative to the self-calibration expectation. A companion paper (Schmidt & Rozo, 2010) investigates how the two types of estimators considered here impact weak lensing peak finding efforts.

description: Dependable power measurements are the backbone of energy-efficient computing systems. The IBM PowerNV platform offers such power measurements through an embedded PowerPC 405 processor: The On-Chip Controller (OCC). Among other system-control tasks, the OCC provides power measurements for several domains, such as system, CPU, and GPU. This paper provides a detailed description and an in-depth evaluation of these OCC-provided power measurements. For that, we describe the provided interfaces themselves and experimentally verify their overhead (3.6 us to 10.8 us per access) and readout rate (24.95 Sa/s). We also study the consistency of the reported sensor readouts across the measurement domains and compare it to externally measured data. Furthermore, we estimate the internal sampling rate (1996 Sa/s) by provoking aliasing errors with artificial workloads, and quantify the errors that such aliasing could introduce in practice (for power consumption of processors 12% in our experimental worst-case scenario). Given these insights, practitioners using the IBM PowerNV platform can assess the quality of the embedded measurements, permitting sought-after energy efficiency improvements.

description: Both regular (the zero-momentum ghost dressing function not diverging), also named decoupling, and critical (diverging), also named scaling, Yang-Mills propagators solutions can be obtained by analyzing the low-momentum behaviour of the ghost propagator Dyson-Schwinger equation (DSE) in Landau gauge. The asymptotic expression obtained for the regular or decoupling ghost dressing function up to the order ${\cal O}(q^2)$ fits pretty well the low-momentum ghost propagator obtained through the numerical integration of the coupled gluon and ghost DSE in the PT-BFM scheme. Furthermore, when the size of the coupling renormalized at some scale approaches some critical value, the PT-BFM results seems to tend to the the scaling solution as a limiting case. This critical value of the coupling is compared with the lattice estimate for the Yang-Mills QCD coupling and the latter is shown to lie much above the former.

description: Elderly residents of long-term care facilities (LTC) have difficulty accessing dental services. Aiming to improve access for this population, the Geriatric Dental Program (GDP) was established by the UBC Faculty of Dentistry in 2002. Within the GDP, elderly LTC residents receive fee-for-service dental treatment. The objective of this research is to explore whether having access to the GDP services had an impact on the life of the patients’ relatives (family members). This research hopes to better understand how quality of health in relation to dental health extends to relatives who are responsible for the frail elderly patients who receive the dental care. Such understanding will contribute to our recognition of a more holistic and widespread impact of dental care access to all segments of our society. Methods: Data was collected through semi-structured, face-to-face, audio-recorded interviews with family members of elderly patients from the UBC-GDP. A purposive criterion sampling method was used to select the family members to participate in this study. The final number of participants was determined according to saturation procedures. Interview transcription and data coding procedures were conducted following Saldaña1. All interviews were transcribed verbatim. In a second step, NVivo software was used to code and organize the transcripts into different categories to develop themes. The analysis of the data followed a qualitative, interpretive Thematic Analysis. Results: Final analysis shows that family members are worried about their relatives’ oral health; they believe that it is difficult to find private dentists with geriatric expertise and to make appointments for their family members outside of UBC, and that the UBC program helped them in fulfilling this task. Moreover, the UBC-GDP made their life less stressful and relieved the burden of setting up appointments for their relatives making their life easier. Thus, the UBC GD program positively affected the life of relatives by improving access to dental care services for the growing geriatric segment of our Canadian society. Furthermore, this study shows that the UBC GD program not only improved the perceived oral health but also impacted the relatives’ life in a positive way.

description: The inclusion of nucleonic exchange energy has been a long-standing challenge for the relativistic density functional theory (RDFT) in nuclear physics. We propose an orbital-dependent relativistic Kohn-Sham density functional theory to incorporate the exchange energy with local Lorentz scalar and vector potentials. The relativistic optimized effective potential equations for the local exchange potentials are derived and solved efficiently. The obtained binding energies and charge radii for nuclei are benchmarked with the results given by the traditional relativistic Hartree-Fock approach, which involves complicated nonlocal potentials. It demonstrates that the present framework is not only accurate but also efficient.

description: Testing a database application is a challenging process where both the database and the user interaction have to be considered in the design of test cases. This paper describes a specification-based approach to guide the design of test inputs (both the test database and the user inputs) for a database application and to automatically evaluate the test adequacy. First, the system specification of the application is modelled: (1) the structure of the database and the user interface are represented in a single model, called Integrated Data Model (IDM), (2) the functional requirements are expressed as a set of business rules, written in terms of the IDM. Then, a MCDC-based criterion is applied over the business rules to automatically derive the situations of interest to be tested (test requirements), which guide the design of the test inputs. Finally, the adequacy of these test inputs is automatically evaluated to determine whether the test requirements are covered. The approach has been applied to the TPC-C benchmark. The results show that it allows designing test cases that are able to detect interesting faults which were located in the procedural code of the implementation.

description: Various strange and charmed hadrons were reconstructed with the ATLAS detector in pp collisions at sqrt{s}=7 TeV. The data sample was collected in March-May of 2010 using a minimum-bias trigger. The K^0_S and Lambda^0 kinematic distributions were studied using data corresponding to an integrated luminosity of 190 mub^{-1}. The Xi-+ and Omega-+ baryons were reconstructed in their cascade decays in data corresponding to an integrated luminosity of 250 mub^{-1}. The D*+-, D+- and D_s+- charmed mesons were reconstructed in the range of transverse momentum pT(D^(*))>3.5 GeV and pseudorapidity |eta(D^(*))|<2.1 in data corresponding to an integrated luminosity of 1.4 nb^{-1}. The fitted mass values were found to be in agreement with their world averages while the observed invariant mass resolutions agree with Monte Carlo expectations. This study confirms the high performance of the ATLAS detector for precision tracking measurements.

Weak Lensing Peak Finding: Estimators, Filters, and Biases

description: Large catalogs of shear-selected peaks have recently become a reality. In order to properly interpret the abundance and properties of these peaks, it is necessary to take into account the effects of the clustering of source galaxies, among themselves and with the lens. In addition, the preferred selection of lensed galaxies in a flux- and size-limited sample leads to fluctuations in the apparent source density which correlate with the lensing field (lensing bias). In this paper, we investigate these issues for two different choices of shear estimators which are commonly in use today: globally-normalized and locally-normalized estimators. While in principle equivalent, in practice these estimators respond differently to systematic effects such as lensing bias and cluster member dilution. Furthermore, we find that which estimator is statistically superior depends on the specific shape of the filter employed for peak finding; suboptimal choices of the estimator+filter combination can result in a suppression of the number of high peaks by orders of magnitude. Lensing bias generally acts to increase the signal-to-noise νof shear peaks; for high peaks the boost can be as large as Δν~ 1-2. Due to the steepness of the peak abundance function, these boosts can result in a significant increase in the abundance of shear peaks. A companion paper (Rozo et al., 2010) investigates these same issues within the context of stacked weak lensing mass estimates.

Publisher: name: University of British Columbia

description: Physical inactivity is a major risk factor in chronic disease and Canadians are insufficiently active. Exercise prescription has been shown to be effective but few physicians prescribe it. The purpose of this study was to determine family medicine residents’ perceived importance of exercise prescription, and to assess the factors associated with residents who indicate the strongest conviction to prescribe exercise. All 396 family medicine residents registered in first or second year at the University of British Columbia, during June 2013 - August 2013, were eligible to complete the cross-sectional 49-item survey. The outcome measures were (1) the importance of exercise prescription in future practice (2) perception of their training in exercise medicine (3) change of the importance of exercise prescription over the course of residency. The data were analyzed using descriptive and inferential statistics to assess significant relationships between each independent variable, resident physical activity levels, attitudes/beliefs, current counselling/prescribing behaviours, awareness/knowledge of physical activity guidelines, self-perceived competence in exercise prescription, and perception of training received, to their perceived importance of exercise prescription in future practice. The data were analyzed as continuous or categorical variables primarily using bivariate analysis with statistical significance set at the level of 0.05. The response rate was 80.6% (319/396). 95.6% of residents indicated exercise prescription would be important in their future practice with 37.5% strongly agreeing (termed "prescribers"). Prescribers had stronger beliefs in the importance of physical activity in health (p<0.001), physical inactivity in disease (p<0.001), and higher rates of current exercise counselling (p=0.001), exercise prescription (p=0.001), and competence prescribing exercise (p=0.005) compared to their colleagues. There was no difference between prescribers and non-prescribers regarding their levels of physical activity, knowledge, or perception of training. The importance of exercise prescription did not change over the course of residency. Only 18.6% of all residents feel they receive adequate training and 91% desire more training in exercise medicine. Exercise prescription is important to residents, but residency is not sufficiently preparing them to prescribe exercise effectively.

description: A series of the functionalised pillar[5]arene ureidopyrimidinone derivatives were successfully synthesised by the condensation reaction of mono-amido-functionalised pillar[5]arenes with 2-(1-Imidazolylcarbonylamino)-6-methyl-4-pyrimidinone in dry chloroform. 1H NMR, 2D NOESY spectra and single crystal structure clearly indicated that novel [1]rotaxanes were formed by insertion of longer alkylene chain into the cavities of the pillar[5]arenes. On the other hand, the ureidopyrimidinone-functionalised pillar[5]arenes tend to form the dimer in chloroform and in solid state through the self-complementary quadruple hydrogen bonding of the ureidopyrimidinone.

description: The aim of this paper is to give an explicit formula of the invariant distribution of a quasi-birth-and-death process in terms of the block entries of the transition probability matrix using a matrix-valued orthogonal polynomials approach. We will show that the invariant distribution can be computed using the squared norms of the corresponding matrix-valued orthogonal polynomials, no matter if they are or not diagonal matrices. We will give an example where the squared norms are not diagonal matrices, but nevertheless we can compute its invariant distribution.
