description: The detection and quantification of narrow emission lines in X-ray spectra is a challenging statistical task. The Poisson nature of the photon counts leads to local random fluctuations in the observed spectrum that often results in excess emission in a narrow band of energy resembling a weak narrow line. From a formal statistical perspective, this leads to a (sometimes highly) multimodal likelihood. Many standard statistical procedures are based on (asymptotic) Gaussian approximations to the likelihood and simply cannot be used in such settings. Bayesian methods offer a more direct paradigm for accounting for such complicated likelihood functions but even here multimodal likelihoods pose significant computational challenges. The new Markov chain Monte Carlo (MCMC) methods developed in 2008 by van Dyk and Park, however, are able to fully explore the complex posterior distribution of the location of a narrow line, and thus provide valid statistical inference. Even with these computational tools, standard statistical quantities such as means and standard deviations cannot adequately summarize inference and standard testing procedures cannot be used to test for emission lines. In this paper, we use new efficient MCMC algorithms to fit the location of narrow emission lines, we develop new statistical strategies for summarizing highly multimodal distributions and quantifying valid statistical inference, and we extend the method of posterior predictive p-values proposed by Protassov et al. (2002) to test for the presence of narrow emission lines in X-ray spectra. We illustrate and validate our methods using simulation studies and apply them to the Chandra observations of the high redshift quasar PG1634+706.

description: We have used the ACS camera on HST to obtain (V,I) photometry for 57,000 red-giant stars in the halo of the Leo elliptical NGC 3377. We use this sample of stars to derive the metallicity distribution function (MDF) for its halo field stars, and comment on its chemical evolution history compared with both larger and smaller E galaxies. Our ACS/WFC field spans a radial range extending from 4 to 18 kpc projected distance from the center of NGC 3377 and thus covers a significant portion of this galaxy's halo. We find that the MDF is broad, reaching a peak at [m/H] ~ -0.6$, but containing virtually no stars more metal-poor than log [m/H] = -1.5$. It may, in addition, have relatively few stars more metal-rich than [m/H] = -0.3$, although interpretation of the high-metallicity end of the MDF is limited by photometric completeness that affects the detection of the reddest, most metal-rich stars. NGC 3377 appears to have an enrichment history intermediate between those of normal dwarf ellipticals and the much larger giants. As yet, we find no clear evidence that the halo of NGC 3377 contains a significant population of ``young'' (< 3 Gy) stars.

description: Propagation and tunneling of light through subwavelength photonic barriers, formed by dielectric layers with continuous spatial variations of dielectric susceptibility across the film are considered. Effects of giant heterogeneity-induced non-local dispersion, both normal and anomalous, are examined by means of a series of exact analytical solutions of Maxwell equations for gradient media. Generalized Fresnel formulae, visualizing a profound influence of gradient and curvature of dielectric susceptibility profiles on reflectance/transmittance of periodical photonic heterostructures are presented. Depending on the cutoff frequency of the barrier, governed by technologically managed spatial profile of its refractive index, propagation or tunneling of light through these barriers are examined. Nonattenuative transfer of EM energy by evanescent waves, tunneling through dielectric gradient barriers, characterized by real values of refractive index, decreasing in the depth of medium, is shown. Scaling of the obtained results for different spectral ranges of visible, IR and THz waves is illustrated. Potential of gradient optical structures for design of miniaturized filters, polarizers and frequency-selective interfaces of subwavelength thickness is considered.

description: A theory of the valley and spin Hall effects and resulting accumulation of the valley and spin polarization is developed for ultraclean channels made of two-dimensional semiconductors where the electron mean free path due to the residual disorder or phonons exceeds the channel width. Both ballistic and hydrodynamic regimes of the electron transport are studied. The polarization accumulation is determined by interplay of the anomalous velocity, side-jump and skew scattering effects. In the hydrodynamic regime, where the electron-electron scattering is dominant, the valley and spin current generation and dissipation by the electron-electron collisions are taken into account. The accumulated polarization magnitude and its spatial distribution depend strongly on the transport regime. The polarization is much larger in the hydrodynamic regime as compared to the ballistic one. Significant valley and spin polarization arises in the immediate vicinity of the channel edges due to the side-jump and skew scattering mechanisms.

description: The strong decays of the $π(2070)$, $η(2010)$, $η(2100)$, $η(2190)$, and $η(2225)$ as the $4 ^1S_0$ quark-antiquark states are investigated in the framework of the $^3P_0$ meson decay model. It is found that the $π(2070)$, $η(2100)$, and $η(2225)$ appear to be the convincing $4 ^1S_0$ $q\bar{q}$ states while the assignment of the $η(2010)$ and $η(2190)$ as the $4 ^1S_0$ isoscalar states is not favored by their widths. In the presence of the $π(2070)$, $η(2100)$, and $η(2225)$ being the members of the $4 ^1S_0$ meson nonet, the $4 ^1S_0$ kaon is phenomenologically determined to has a mass of about 2153 MeV. The width of this unobserved kaon is expected to be about 197 MeV in the $^3P_0$ decay model.

description: We have made a detailed proposal for a two-channel quantum dot setup. The energy scales in the problem are such that we are able to make connection with the two-channel Anderson model, which, in spite of being well-known in the context of heavy-Fermion systems remained theoretically elusive until recently and lacked a mesoscopic realization. Verification of our precise and robust predictions for the differential capacitance lineshape of the dot will provide an experimental signature of the two-channel behavior.

description: We study the (standard) cohomology $H^\bullet_{st}(E)$ of a Courant algebroid $E$. We prove that if $E$ is transitive, the standard cohomology coincides with the naive cohomology $H_{naive}^\bullet(E)$ as conjectured by Stienon and Xu. For a general Courant algebroid we define a spectral sequence converging to its standard cohomology. If $E$ is with split base, we prove that there exists a natural transgression homomorphism $T_3$ (with image in $H^3_{naive}(E)$) which, together with the naive cohomology, gives all $H^\bullet_{st}(E)$. For generalized exact Courant algebroids, we give an explicit formula for $T_3$ depending only on the Ševera characteristic clas of $E$.

description: We study the switching behavior of two spin-crossover molecules residing in a nanojunction device consisting of two closely spaced gold electrodes. The spin states are monitored through a real-time measurement of the resistance of the junction. A statistical analysis of the resistance values, the occupation probabilities, and the lifetimes of the respective spin states shows that the two spin-crossover molecules are coupled to each other. We extract the parameters for a minimal model describing the two coupled spin-crossover molecules. Finally, we use the time dependence of factorial cumulants to demonstrate that the measured data indicates the presence of interactions between the two spin-crossover molecules.

Conflict and resource development
Creators: name: McKellar, Richard David
Publisher: name: University of British Columbia
Year: 2010

description: Interorganisational conflict is common when public resources are developed for the benefit of identifiable private interest groups. In many instances it is not advisable or possible to avoid such conflict, but rather the conflict situation should be addressed and if possible managed to avoid environmentally, economically or socially destructive outcomes. In this thesis I discuss how conflict might be addressed in resource development planning, specifically using the context of the route selection and site design levels of planning for linear transportation corridors in wilderness areas. First I trace the planning and implementation histories of three corridors to determine the "foci" and outcomes of conflict in these instances. Then, using a systems approach to planning and decision-making, I determine those aspects of the planning and decision-making system which generated the conflict foci and which were therefore inappropriate or suboptimal. From this I suggest ways by which the system might be improved. Thereafter I review some of the recent conflict management literature and propose a conflict management model having the following elements: i) use of a mediating agency with the authority to require involvement in the planning process but without the authority to impose a plan or solution; ii) involvement of representatives of all major interest groups; iii) analysis of the situation into its cognitive, interest and value components, and analysis and discussion of these components; and iv) having a means of overcoming well-defined deadlocks in the process in a manner that' is appropriate in a democratic society. These elements are substantially similar to the suggestions for improvements to the planning and decision-making system made earlier. Next I review in detail the involvement of different organisations in the planning process for one of the corridors previously studied, and compare it with the conflict management model: i) no mediating agency with the authority outlined above was involved; ii) the involvement of some interest groups was not welcomed or permitted by the proponent agency; iii) only cognitive information was used in discussions and this was not usually objectively developed or verified but rather was disputed; iv) there was no attempt to clearly define the pertinent issues and defined method of overcoming deadlocks. Finally I suggest how the planning and decision-making process for the corridor might have occured had the conflict management model been utilised.

description: Effective field theories are useful tools to search for physics beyond the Standard Model (SM). However, effective theories can lead to non-unitary behavior with fastly growing amplitudes. This unphysical behavior may lead to large sensitivity to SM deviations, making necessary a unitarization of the amplitudes prior to a comparison with experiment. In the present work, we focus on all the processes entering the two-Higgs production by longitudinal $WW$ scattering: we perform a full one-loop calculation of all relevant processes, we determine the necessary counterterms in the on-shell scheme, and we study how the full inclusion of the gauge degrees of freedom modifies the previously computed masses and widths of the dynamical resonances arising from the unitarization process in the vector-isovector channel. Altogether, we are able to provide the technical tools that are needed to study the low-energy couplings in the Higgs effective theory under the requirements of unitarity and causality.

The pair correlation function and bond-orientational correlation function was calculated in the Yukawa system. An algebraic decay of the bond orientational correlation function was observed. By ruling out the coexistence region, only a unstable hexatic phase was found in the Yukawa systems. But our work shows that the melting of the Yukawa systems is a two-stage melting not consist with the KTHNY theory and the isotropic liquid and the hexatic phase coexistence region was found. Also we have studied point defects in two-dimensional Yukawa systems.

description: The Nymph, the incarnation of the female figure in movement, is the central object of this essay, starting from Aby Warburg's encounter with the representation of a young maiden who, with an almost winged step, appears in the scene of the fresco of the Nativity of Saint John in Santa Maria Novella's Main Chapel (Florence, Italy). This young woman who Warburg called “Ninfa” has become, over time, the synthesis of a thought that placed, at the center of the theory of the image, the notion of survival (Nachleben) and the power of expressive formulas or formulas of pathos (Pathosformel). Based on the Warburgian considerations on the Nymph, this essay exposes the revision that Georges Didi-Huberman carries out in his book Ninfa moderna, in which the Nymph disrobes, and her condition as a Pathosformel is then transferred to the fallen cloth (reliquat). This research analyzes the way in which Didi-Huberman finds the survival of the Pathosformel Nymph starting with the Santa Maria Novella fresco all the way through the remnants of twentieth-century Paris, thus confirming that the movement of the young Florentine remains after the cloth falls. The concluding objective of this essay is, then, to analyze what elements confer this reliquat (fallen cloth) its status as a Pathosformel.

description: We investigate the widths of the recently observed charmonium like resonances X(3872), Z(4430) and Z_2(4250) using QCD sum rules. Extending previous analyses regarding these states as diquark-antiquark states or molecules of D mesons, we introduce the Breit-Wigner function in the pole term. We find that introducing the width increases the mass at small Borel window region. Using the OPE up to dimension eight, we find that the sum rules based on interpolating current with molecular components give a stable Borel curve from which both the masses and widths of these resonances can be well obtained. Thus the QCD sum rule approach strongly favors the molecular description of these states.

description: Targets are essential in problems such as object tracking in cluttered or textureless environments, camera (and multi-sensor) calibration tasks, and simultaneous localization and mapping (SLAM). Target shapes for these tasks typically are symmetric (square, rectangular, or circular) and work well for structured, dense sensor data such as pixel arrays (i.e., image). However, symmetric shapes lead to pose ambiguity when using sparse sensor data such as LiDAR point clouds and suffer from the quantization uncertainty of the LiDAR. This paper introduces the concept of optimizing target shape to remove pose ambiguity for LiDAR point clouds. A target is designed to induce large gradients at edge points under rotation and translation relative to the LiDAR to ameliorate the quantization uncertainty associated with point cloud sparseness. Moreover, given a target shape, we present a means that leverages the target's geometry to estimate the target's vertices while globally estimating the pose. Both the simulation and the experimental results (verified by a motion capture system) confirm that by using the optimal shape and the global solver, we achieve centimeter error in translation and a few degrees in rotation even when a partially illuminated target is placed 30 meters away. All the implementations and datasets are available at https://github.com/UMich-BipedLab/optimal_shape_global_pose_estimation.
Ammonium and methylammonium uptake by the nitrogen-fixing bacterium Azotobacter vinelandii
Creators: name: Moore, Richard Atwood
Publisher: name: University of British Columbia
Year: 2010

description: Azotobacter vinelandii, grown with ammonium as a nitrogen source, was shown to possess an active transport system which could concentrate ammonium 44 to 58 fold. Ammonium uptake was inhibited by the glutamate analog methionine sulfone. The properties of the ammonium uptake system (transport and metabolism) were investigated using the ammonium analog methylammonium. The uptake of methylammonium was inhibited by arsenate indicating that phosphate bond energy was required. Methylammonium uptake was also inhibited by the electron transport inhibitor, cyanide, and the uncoupler, carbonyl cyanide- m-chlorophenyl hydrazone. However, it was shown that these agents served to deplete ATP pools in A. vinelandii. Uptake of methylammonium was sensitive to a Tris-Mg⁺⁺ shock treatment suggesting the possible involvement of a periplasmic binding protein, however, methylammonium-binding activity was not found in periplasmic extracts. A. vinelandii was shown to exhibit a positive chemotactic response toward ammonium as well as acetate, glucose and sucrose. Comparison of outer membrane proteins from nitrogen-fixing cells and ammonium-grown cells revealed the production of a 44,000 dalton protein in membranes from nitrogen-fixing cells. Inner membranes from nitrogen-fixing cells contained a 41,000 dalton protein which was present in low amounts in the membranes of ammonium-grown cells. It was shown that the outer membranes of ammonium-grown cells contained a major protein which was "heat modifiable" in that its mobility on sodium dodecyl sulfate-polyacrylamide gel electrophoresis was determined by the temperature of solubilization prior to electrophoresis. Methylammonium was shown to be metabolized to N-methylglutamine. Strain JK301, an L-methionine-D,L-sulfoximine-resistant mutant of A. vinelandii, was unable to catalyse N-methylglutamine synthesis in vivo or in cell-free extracts and lacked detectable methylammonium uptake activity. Glutamine synthetase in cell-free extracts of JK301 had a Km for glutamate approximately three-fold higher and a Vmax approximately fourfold lower than enzyme from the wild type strain. It was concluded that methylammonium uptake reflects, in part, metabolism to N-methylglutamine by glutamine synthetase.

description: We study the Standard Model with gauged $\mathbb Z_{N=2,3,6}^{(1)}$ subgroups of its $\mathbb Z_6^{(1)}$ 1-form global symmetry, making the gauge group $SU(3) \times SU(2)\times U(1) \over \mathbb Z_N$. We show that, on a finite $\mathbb T^3$, there are self-dual instantons of fractional topological charge. They mediate baryon- and lepton-number violating processes. We compare their amplitudes to the ones due to the usual BPST-instantons. We find that the small hypercharge coupling suppresses the fractional-instanton contribution, unless the torus size is taken sub-Planckian, or extra matter is added above the weak scale. We also discuss these results in light of the cosmological bounds on the torus size.

description: Cephennium (Macroderus) verrens nov.sp. (Figs 16, 66, Map 3)
Type material: Holotype ♂: "E – No. 9; Andalucia, Sierra de Segura, 20 km S Pontones, 1830 m, 38°00'41N, 02°44'35W, 9.IV.2003, leg. V. Assing / Holotypus ♂ Cephennium verrens sp. n. det. V. Assing 2020" (cAss). Paratypes: 1♂, 1♀: same data as holotype (cAss); 1♂, 1♀: "E – No. 5; Andalucia. Sierra de Segura, 15 km S Pontones, 1580 m, 38°04'23N, 02°41'19W, 7.IV.2003, leg. V. Assing " (Ass).
Etymology: The specific epithet is the present participle of the Latin verb verrere (to sweep, to brush) and alludes to the broom-shaped internal structures of the aedeagus.
Description: Body length 1.3-1.4 mm. Habitus as in Fig. 16. Colouration palereddish. Pubescence of pronotum and elytra rather short and depressed. Eyes composed of approximately six ommatidia. Pronotum approximately 1.35 times as broad as long. Elytra with anterior sulci approximately as long as the combined length of the basal four antennomeres. Other external characters as in C. alacantae.
♂: metaventrite shallowly impressed; aedeagus (Fig. 66) approximately 0.35 mm long; apex of median lobe convex in ventral view; internal structures brush-shaped; parameres apically nearly reaching apex of median lobe.
Comparative notes: Cephennium verrens is distinguished from the geographically close C. cujonicum and C. segurae particularly by a larger aedeagus with an apically convex ventral process and internal structures of different shape.
Distribution and natural history: The species was collected in two localities to the south of Pontones in the Sierra de Segura (Map 3). The specimens were sifted in a north slope near snow at an altitude of 1830 m and found under stones in a grassy valley near a pine forest at an altitude of 1580 m.

description: The Schmidt decomposition is an important tool in the study of quantum systems especially for the quantification of the entanglement of pure states. However, the Schmidt decomposition is only unique for bipartite pure states, and some multipartite pure states. Here a generalized Schmidt decomposition is given for states which are equivalent to depolarized pure states. Experimental methods for the identification of this class of mixed states are provided and some examples are discussed which show the utility of this description. A particularly interesting example provides, for the first time, an interpretation of the number of negative eigenvalues of the density matrix.

description: We investigate retrolensing of sunlights reflected by a photon sphere and by a potential barrier near an antiphoton sphere around a Reissner-Nordström naked singularity. We apply the deflection angles of light rays in strong deflection limits to the retrolensing. We show that the retrolensing by the photon sphere around the Reissner-Nordström naked singularity can be brighter than the one around a Reissner-Nordström black hole because of the existence of the rays which reflected by the potential barrier.

description: The Danish mobile library as a concrete place in a material vehicle has changed remarkably throughout the years. The modern mobile library is a place for sociability. At the stops of the library route people meet, discussing books and other materials: The bus or truck itself has changed from just being a transportation unit to a place for rest, tranquility, immersion and information. In the article mobility is defined as the possibility to move artefacts, people, and encounters to different locations, thus creating new kinds of relationships and meaning. The aim of the article is to be part of the “critical engagement in and through mobilities studies” in which “researchers are making a difference to the ways in which (im)mobilities are conceived of, in research, design and areas of public policy” (Büscher et al. 2011: 14).

Why walk when you can teleport?

Publisher: name: Akademisk kvarter | Academic Quarter

description: Travel constitutes a significant activity in the majority of Massively Multiplayer Online Roleplaying Games (MMORPGs), whether players are pursuing quests, trading, adventuring or simply exploring. Yet not all journeys are equal, and the roles of, and responses to, various journeys demonstrate a number of interesting interpretations of travel. From one perspective, journeys in games are simply consumers of time: notably, World of Warcraft obtained the nickname “World of Walking” due to player perceptions that there was too much travel involved. Yet it is intriguing that some players voluntarily undertake extensive journeys, which are often difficult (in gameplay terms) and time-consuming, when more convenient routes are available. This article seeks to consider the many roles of travel in MMORPGs, and to reflect on ideas of the journey as, among other things, labour (travail), a rite of passage, and a means of saying goodbye.

A new mechanism for massive binary black hole evolution

description: It is still unknown how the BBH evolves after its semi-major axis reached to the sub-parsec/parsec scale where the dynamical friction with the neighboring stars is no longer effective (the so-called the final parsec problem). In this paper, we propose a new mechanism by which the massive BBH can naturally coalesce within a Hubble time. We study the evolution of the BBH with triple disks which are composed of an accretion disk around each black hole and one circumbinary disk surrounding them. While the circumbinary disk removes the orbital angular momentum of the BBH via the binary-disk resonant interaction, the mass transfer from the circumbinary disk to each black hole adds some fraction of its angular momentum to the orbital angular momentum of the BBH. We find that there is a critical value of the mass-transfer rate where the extraction of the orbital angular momentum from the BBH is balanced with the addition of the orbital angular momentum to the BBH. The semi-major axis of the BBH decays with time whereas the orbital eccentricity of the BBH grows with time, if the mass transfer rate is smaller than the critical one, and vice versa. Its evolutionary timescale is characterized by the product of the viscous timescale of the circumbinary disk and the ratio of the total black hole mass to the mass of the circumbinary disk. Since a minimum value of the critical mass-transfer rate is larger than the Eddington accretion rate of massive black holes with masses in the 10^{6}M_{sun} to $10^{9}M_{sun} range, it is promising that the critical mass-transfer rate is larger than the mass transfer rate. Most of massive BBHs, therefore, enable to merge within a Hubble time by the proposed mechanism, which helps to solve the final parsec problem.

description: The article attempts to map how a televisions series is spread into social media. With the voyage of discovery as metaphor as a point of departure and virtual ethnography as method the BBC modernization of Sherlock Holmes into Sherlock is the focus of interest. The aim is to examine how social media mediate meaning, significance and new content in the series and to describe, explain and interpret the motives people have to spend energy and time to expand the universe of the series with their own productions and give feedback to others who do the same.

Identification-of-self through a yoga-travel-spirit nexus
Creators: name: Holladay, Patrick J.
name: Ponder, Lauren M.
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: This article examines a heuristic paradigm of a yoga-spirit-travel nexus and its agency on the identification-of-self. In the ancient Sanskrit yoga means union or yoke. Yoga practice may act as a yoking or linking element between self-identity and spiritual development such that yoga travel may lead to the enhancement of self-identity for the yogi traveler. Conceptually, the practice of yoga acts as a catalyst for travel to partake in foreign yoga experiences. Both during travel and in the travel destination, the engaged spiritual capital via yoga may act as an uplifiting transformative agent for identity formation. We conclude that by linking self-identification to a yoga-travel-spirit nexus a foundation of self-enlightenment may emerge.

Formation, diffusion and accreting pollution of DB white dwarfs

description: Over 1500 DBZ or DZ white dwarfs (WDs) have been observed so far, and polluted atmospheres with metal elements have been found among these WDs. The surface heavy element abundances of known DBZ or DZ WDs show an evolutionary sequence. By using Modules for Experiments in Stellar Evolution, we create DB WDs, and simulate the element diffusion due to high gravitational fields and the metal-rich material accretion coming from the planet disrupted by the WD. In our models, the input parameters ($α_{\rm MLT}$, $α_{\rm th}$ and $Z$) have very weak effect on DB WD structures including interior temperatures, chemical profiles and convective zones.The mass-accretion rate and the effective temperature of DB WDs determine the abundances of heavy elements. The evolutionary sequence of Ca element for about 1500 observed DB or DBZ WDs cannot be explained by the model with a constant mass-accretion rate, but is consistent well with the model in which the mass-accretion rate decreases by one power law when $T_{\rm eff}>10$ kK and slightly increases by another power law when $T_{\rm eff}<10$ kK. The observed DB WD evolutionary sequence of heavy element abundances originates from WD cooling and the change of mass-accretion rate.

A model of the UNIX time-sharing system under disk saturation
Creators: name: Brachman, Barry Jeffrey
Publisher: name: University of British Columbia
Year: 2010

description: A deterministic model of the UNIX time-sharing system under disk saturation is presented and a performance experiment on a PDP-11/34 is conducted to establish the validity and accuracy of the model. The basis of the model is that the ratio of mean file system access rates between two different systems can provide, under certain circumstances, a useful performance comparison between the two systems. Given several workload and system parameters as well as the elapsed time to perform the workload, the model predicts from a second set of parameters the elapsed time to perform the second workload. Workload, hardware, and internal system parameters are identified and tools are constructed to record these parameters. A controlled experiment, using a synthetic workload, is then conducted. The results are analyzed and the model is evaluated. The model is extended in response to regularities discovered in the measurement data. Sample applications of the model are given. The suitability of the tools developed and the methods used are discussed.
