description: Testing theories of angular-momentum acquisition of rotationally supported disc galaxies is the key to understand the formation of this type of galaxies. The tidal-torque theory tries to explain this acquisition process in a cosmological framework and predicts positive autocorrelations of angular-momentum orientation and spiral-arm handedness on distances of 1Mpc/h. This disc alignment can also cause systematic effects in weak-lensing measurements. Previous observations claimed discovering such correlations but did not account for errors in redshift, ellipticity and morphological classifications. We explain how to rigorously propagate all important errors. Analysing disc galaxies in the SDSS database, we find that positive autocorrelations of spiral-arm handedness and angular-momentum orientations on distances of 1Mpc/h are plausible but not statistically significant. This result agrees with a simple hypothesis test in the Local Group, where we find no evidence for disc alignment. Moreover, we demonstrate that ellipticity estimates based on second moments are strongly biased by galactic bulges, thereby corrupting correlation estimates and overestimating the impact of disc alignment on weak-lensing studies. Finally, we discuss the potential of future sky surveys. We argue that photometric redshifts have too large errors, i.e., PanSTARRS and LSST cannot be used. We also discuss potentials and problems of front-edge classifications of galaxy discs in order to improve estimates of angular-momentum orientation.

description: In this qualitative exploratory study, based on my own personal experience of perinatal loss and T. A. Rando's model of Complicated Mourning, I conducted long interviews with 25 individuals, attended several parent bereavement support group meetings, facilitated a focus group and held informal interviews with helping professionals to examine experiences of perinatal loss and perinatal mourning. I discuss the interaction between social, psychological and physiological factors that contribute to complicate mourning in order to develop a picture of why perinatal loss is so difficult to resolve. I also describe the methods parents employ to honour their feelings and experiences of loss, and how, through loss and their creative responses to it, parents find themselves and their worldviews transformed. As a. finishing step in the research, I conducted a followup survey to explore the therapeutic effects of research participation on interviewees. Finally, I discuss how this research has affected my understanding of my own perinatal loss.

description: Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B is known to host a giant planet while no planets have yet been detected around 16 Cyg A. Stellar parameters are derived directly from our high-quality spectra, and the stars are found to be physically similar, with Delta_T_eff = +43 K, Delta_logg = -0.02 dex, and Delta_xi = +0.10 km/s (in the sense of A - B), consistent with previous findings. Abundances of 15 elements are derived and are found to be indistinguishable between the two stars. The abundances of each element differ by <= 0.026 dex, and the mean difference is +0.003 +/- 0.015 (sigma) dex. Aside from Li, which has been previously shown to be depleted by a factor of at least 4.5 in 16 Cyg B relative to 16 Cyg A, the two stars appear to be chemically identical. The abundances of each star demonstrate a positive correlation with the condensation temperature of the elements (T_c); the slopes of the trends are also indistinguishable. In accordance with recent suggestions, the positive slopes of the [m/H]-T_c relations may imply that terrestrial planets have not formed around either 16 Cyg A or 16 Cyg B. The physical characteristics of the 16 Cyg system are discussed in terms of planet formation models, and plausible mechanisms that can account for the lack of detected planets around 16 Cyg A, the disparate Li abundances of 16 Cyg A and B, and the eccentricity of the planet 16 Cyg B b are suggested.

description: This paper outlines a simple approach to evaluate the atmospheric composition of hot rocky planets by assuming different types of planetary composition and using corresponding model calculations. To explore hot atmospheres above 1000 K, we model the vaporization of silicate magma and estimate the range of atmospheric compositions according to the planet's radius and semi-major axis for the Kepler February 2011 data release. Our results show 5 atmospheric types for hot, rocky super-Earth atmospheres, strongly dependent on the initial composition and the planet's distance to the star. We provide a simple set of parameters that can be used to evaluate atmospheric compositions for current and future candidates provided by the Kepler mission and other searches.

description: We characterize the kinematics, morphology, stellar populations and star formation histories of a sample of massive compact galaxies in the nearby Universe, which might provide a closer look to the nature of their high redshift (z > 1.0) massive counterparts. We find that nearby compact massive objects show elongated morphologies and are fast rotators. New high-quality long-slit spectra show that they have young mean luminosity-weighted ages (< 2Gyr) and solar metallicities or above ([Z/H]> 0.0). No significant stellar population gradients are found. The analysis of their star formation histories suggests that these objects have experienced recently enormous bursts which, in some cases, represent unprecedented large fractions of their total stellar mass. These galaxies seem to be truly unique, as they do not follow the characteristic kinematical and stellar population patterns of present-day massive ellipticals, spirals or even dwarfs.

description: Optical frequency combs allow for precise measurement of optical frequencies and are used in a growing number of applications beyond spectroscopy and optical frequency metrology. A class of compact microresonator based frequency comb generators has emerged recently based on (hyper)-parametric frequency conversion, mediated by the Kerr-non-linearity, of a continuous wave laser beam. Despite the rapid progress and the emergence of a wide variety of micro-resonator Kerr-comb platforms, an understanding of the dynamics of the Kerr comb formation is still lacking. In particular the question in which regime low phase noise performance can be achieved has so far not been answered but is of critical importance for future application of this technology. Here an universal, platform independent understanding of the Kerr-comb formation dynamics based on experimental observations in crystalline MgF2 and planar Si3N4 comb generators is given. This explains a wide range of hereto not understood phenomena and reveals for the first time the underlying condition for low phase noise performance.

description: Dark energy models based on f(R) theory have been extensively studied in literature to realize the late time acceleration. In this paper, we have chosen a viable f(R) model and discussed its effects on the dynamical instability of expansionfree fluid evolution generating a central vacuum cavity. For this purpose, contracted Bianchi identities are obtained for both the usual matter as well as dark source. The term dark source is named to the higher order curvature corrections arising from f(R) gravity. The perturbation scheme is applied and different terms belonging to Newtonian and post Newtonian regimes are identified. It is found that instability range of expansionfree fluid on external boundary as well as on internal vacuum cavity is independent of adiabatic index $Γ$ but depends upon the density profile, pressure anisotropy and f(R) model.

description: Calculating the galaxy merger rate requires both a census of galaxies identified as merger candidates, and a cosmologically-averaged `observability' timescale T_obs(z) for identifying galaxy mergers. While many have counted galaxy mergers using a variety of techniques, T_obs(z) for these techniques have been poorly constrained. We address this problem by calibrating three merger rate estimators with a suite of hydrodynamic merger simulations and three galaxy formation models. We estimate T_obs(z) for (1) close galaxy pairs with a range of projected separations, (2) the morphology indicator G-M20, and (3) the morphology indicator asymmetry A. Then we apply these timescales to the observed merger fractions at z < 1.5 from the recent literature. When our physically-motivated timescales are adopted, the observed galaxy merger rates become largely consistent. The remaining differences between the galaxy merger rates are explained by the differences in the range of mass-ratio measured by different techniques and differing parent galaxy selection. The major merger rate per unit co-moving volume for samples selected with constant number density evolves much more strongly with redshift (~ (1+z)^(+3.0 \pm 1.1)) than samples selected with constant stellar mass or passively evolving luminosity (~ (1+z)^(+0.1 \pm 0.4)). We calculate the minor merger rate (1:4 < M_{sat}/M_{primary}

description: We define an ensemble of projection operators, each of which has an exact associated Nakajima-Zwanzig master equation for quantum open system evolution. A mean field approximation for the memory kernels is introduced that yields, for an optimally chosen projection operator, a completely determined inhomogeneous master equation. Previous proofs of positivity and equilibration are extended to these new inhomogeneous non-Markovian master equations. We study a nitrogen vacancy center in diamond interacting with 13C impurities to illustrate the method.

description: During the late-eighteenth century, a number of different aria types emerged in Italian opera seria in conjunction with the establishment of the Classical style. One emergent aria form was the two-part, two-tempo rondo aria which first appeared in the 1760s and became standardized in the early 1780s. In its most conventional form, the rondo aria exhibited a two-tempo framework that includes an andante section followed by an allegro part. The andante most typically is constructed in a ternary fashion; the allegro likely contains gavotte rhythms. Examples of the rondo aria form can be found in Mozart's late operas and concert arias, as well as in the works of his Italian contemporaries, such as Giuseppe Sarti. Through various modifications, such as the introduction of pertichini, and the addition of a tempo di mezw, the rondo aria nucleus was expanded to encompass a continued preference for dynamic expression. This rondo aria is the direct ancestor of the cantabile-cabaletta convention highly evident in Italian opera of the mid-nineteenth century.

description: This thesis explores how translational shifts affect the interpretive possibilities harboured by, and the literary quality of a series of, translations of a single text. This investigation is pursued by means of a case study in which three English translations of Annette von Droste-Hulshoff's Novelle, Die Judenbuche (1842), are analyzed. The analysis of the translations employs both a close reading of the original and its reception history to provide the standard against which the English texts are evaluated. The framework for the evaluation thus established, the translations are discussed in terms of their aesthetic quality and their interpretive potentiality in comparison to the original. Based on these criteria, the analysis of the three English versions of Die Judenbuche reveals that translational shifts in most cases significantly affected the possibility of deriving the same meanings from the translation as were derived from the original in its history of reception.

description: We investigate the spectral variability of the Seyfert galaxy Fairall 9 using almost 6 years of monitoring with the Rossi X-ray Timing Explorer (RXTE) with an approximate time resolution of 4 days. We discover the existence of pronounced and sharp dips in the X-ray flux, with a rapid decline of the 2--20 keV flux of a factor 2 or more followed by a recovery to pre-dip fluxes after ~10 days . These dips skew the flux distribution away from the commonly observed log-normal distribution. Dips may result from the eclipse of the central X-ray source by broad line region (BLR) clouds, as has recently been found in NGC 1365 and Mrk 766. Unlike these other examples, however, the clouds in Fairall 9 would need to be Compton-thick, and the non-dip state is remarkably free of any absorption features. A particularly intriguing alternative is that the accretion disk is undergoing the same cycle of disruption/ejection as seen in the accretion disks of broad line radio galaxies (BLRGs) such as 3C120 but, for some reason, fails to create a relativistic jet. This suggests that a detailed comparison of Fairall 9 and 3C120 with future high-quality data may hold the key to understanding the formation of relativistic jets in AGN.

description: Maria Janitschek is one of the many forgotten German female authors of the turn of the century. She has written an array of works including prose and poetry about such typically female themes as marriage, love, family, religion. Reaction to her works varies: some critics consider her an advocate of the women's movement , others consider her works an example of "Trivialliteratur" or "nervöse Kunst", while still others find her work completely worthless. This ambivalence among scholars is a reflection of an ambivalence present in her actual works; this is articulated by her women characters and their problems. Maria Janitschek recognized the difficulties which existed for women, but offered no realistic alternatives or solutions which would allow them to change their situation. Her women cannot break free from old traditions to enter the realm of the new, although they clearly attempt to make this transition. Maria Janitschek's works reflect the sentiments and desires for change at the turn of the century, but she offers no clear vision of how this can be achieved.

description: The effects of disorders on the quantum coherence for many-bosons are studied in a double well model. For the ground state, the disorder enhances the quantum coherence. In the deep Mott regime, dynamical evolution reveals periodical collapses and revivals of the quantum coherence which is robust against the disorder. The average over variations in both the on-site energy and the interaction reveals a beat phenomenon of the coherence-decoherence oscillation in the temporal evolution.

We find that the different combinations of the pion-bound and neutron-hole states dominate the spectra at different scattering angles because of the matching condition of the reaction. We conclude that the observation of the (d,3He) reaction at finite angles will provide the systematic information of the pionic bound states in each nucleus and will help to develop the study of the pion properties and the partial restoration of chiral symmetry in nuclei.

description: Superstring theory and other supersymmetric theories predict the existence of relatively light, weakly interacting scalar particles, called moduli, with a universal form of coupling to matter. Such particles can be emitted from cusps of cosmic strings, where extremely large Lorentz factors are achieved momentarily. Highly boosted modulus bursts emanating from cusps subsequently decay into gluons, they generate parton cascades which in turn produce large numbers of pions and then neutrinos. Due to very large Lorentz factors, extremely high energy neutrinos, up to the Planck scale and above, are produced. For some model parameters, the predicted flux of neutrinos with energies $\gtrsim 10^{21}$ eV is observable by JEM-EUSO and by the future large radio detectors LOFAR and SKA.

description: This paper is devoted to study the charged perfect fluid cylindrical gravitational collapse. For this purpose, we find a new analytical solution of the field equations for non-static cylindrically symmetric spacetime. We discuss physical properties of the solution which predict gravitational collapse. It is concluded that in the presence of electromagnetic field the outgoing gravitational waves are absent. Further, it turns out that when longitudinal length reduces to zero due to resultant action of gravity and electromagnetic field, then the end state of the gravitational collapse is a conical singularity. We also explore the smooth matching of the collapsing cylindrical solution to a static cylindrically symmetric solution. In this matching, we take a special choice of constant radius of the boundary surface. We conclude that the gravitational and Coulomb forces of the system balance each other.

description: Gamma-rays and neutrons are the only sources of information on energetic ions present during solar flares and on properties of these ions when they interact in the solar atmosphere. The production of γ-rays and neutrons results from convolution of the nuclear cross-sections with the ion distribution functions in the atmosphere. The observed γ-ray and neutron fluxes thus provide useful diagnostics for the properties of energetic ions, yielding strong constraints on acceleration mechanisms as well as properties of the interaction sites. The problem of ion transport between the accelerating and interaction sites must also be addressed to infer as much information as possible on the properties of the primary ion accelerator. In the last couple of decades, both theoretical and observational developments have led to substantial progress in understanding the origin of solar γ-rays and neutrons. This chapter reviews recent developments in the study of solar γ-rays and of solar neutrons at the time of the RHESSI era. The unprecedented quality of the RHESSI data reveals γ-ray line shapes for the first time and provides γ-ray images. Our previous understanding of the properties of energetic ions based on measurements from the former solar cycles is also summarized. The new results-obtained owing both to the gain in spectral resolution (both with RHESSI and with the non solar-dedicated INTEGRAL/SPI instrument) and to the pioneering imaging technique in the γ-ray domain-are presented in the context of this previous knowledge. Still open questions are emphasized in the last section of the chapter and future perspectives on this field are briefly discussed.

description: In this thesis, we propose a unified analysis of two long-disputed structures in Chinese: the bei and the ha constructions, which exhibit a number of unexpected properties given standard assumptions with respect to passivization and Case theory since: i) the bei passive cannot suppress the verb's Case and theta-role assigning abilities; ii) the Agent DP is not demoted; iii) DP movement does not occur to satisfy the Case Filter. It is shown that many of the puzzling properties in these constructions, especially the unusual word order, can be treated as consequences of some general principles. While the standard analysis of passivization is challenged, strong empirical evidence is found favoring the VP-Internal Subject Hypothesis, the UTAH (Baker 1988), the proposal that DP movement occurs to satisfy the requirement that a Case assigner discharge Case (Fukui and Speas 1986), and that a chain may receive more than one Case feature.

description: We have measured dramatic flux and spectral variations through the 0.193d orbit of the optical counterpart of the unidentified gamma-ray source 0FGL J2339.8-0530. This compact object companion is strongly heated, with T_eff varying from ~6900K (superior conjunction) to <3000K at minimum. A combined fit to the light curve and radial velocity amplitudes implies M_1 ~ 0.075M_sun, M_2 ~ 1.4 M_sun and inclination i ~ 57deg. Thus this is a likely `black widow' system with Edot~10^{34-34.5} erg/s pulsar driving companion mass loss. This wind, also suggested by the X-ray light curve, may prevent radio pulse detection. Our measurements constrain the pulsar's reflex motion, increasing the possibility of a pulse detection in the gamma-ray signal.

description: This thesis attempts to document the research and process of the director of a production of Timberlake Wertenbaker's The Grace of Mary Traverse presented at The University of Calgary October 19-22 and 25-29, 1994. Furthermore, this thesis attempts to provide the reader with a record of the experience of directing the play. To that end the more objective material is inter-woven with personal reflections upon the nature of the directorial choices made within the production. In addition, much of the introductory material serves to present the author's personal socio-political agenda to the reader. The thesis continues with a biography of the playwright and a textual analysis in chapter one, an historical overview in chapter two and a dramaturgical interpretation of the text in chapters three, four and five. A short conclusion ties the disperate threads of the anaysis together and reinforces some of the thesis' major points.

description: High-velocity clouds (HVC), fast-moving ionized and neutral gas clouds found at high galactic latitudes, may play an important role in the evolution of the Milky Way. The extent of this role depends sensitively on their distances and total sky covering factor. We search for HVC absorption in HST high resolution ultraviolet spectra of a carefully selected sample of 133 AGN using a range of atomic species in different ionization stages. This allows us to identify neutral, weakly ionized, or highly ionized HVCs over several decades in HI column densities. The sky covering factor of UV-selected HVCs with |v_LSR|>90 km/s is 68%+/-4% for the entire Galactic sky. We show that our survey is essentially complete, i.e., an undetected population of HVCs with extremely low N(H) (HI+HII) is unlikely to be important for the HVC mass budget. We confirm that the predominantly ionized HVCs contain at least as much mass as the traditional HI HVCs and show that large HI HVC complexes have generally ionized envelopes extending far from the HI contours. There are also large regions of the Galactic sky that are covered with ionized high-velocity gas with little HI emission nearby. We show that the covering factors of HVCs with 90170 km/s are largely associated with the Magellanic Stream at b<0 and its leading arm at b>0 as well as other large known HI complexes. Therefore there is no evidence in the Local Group that any galaxy shows a population of HVCs extending much farther away than 50 kpc from its host, except possibly for those tracing remnants of galaxy interaction.

description: Thermal radiation is a naturally abundant form of light that is continuously emitted from objects above absolute zero. Because this form of electromagnetic radiation is invisible to the human eye, much of human and machine perception neglects the rich information that is present in infrared energy. By harvesting the spectral and polarimetric characteristics of thermal signals, thermal imaging can deliver an enormous impact to remote sensing, machine perception, autonomous navigation, and biomedical applications. The goal of this thesis is to present numerous techniques that enable the extraction of the vast information available via thermal radiation.This thesis investigates a more robust and approachable method of providing spectral and polarimetric resolution to short-wave infrared cameras. Through the application of a liquid crystal interferometer, this research demonstrates an electrically-tunable spectral imaging platform that is compact, robust, cost-effective, and accurate, offering a durable solution for remote sensing and autonomous navigation. This thesis also examines the design of filters specific to the short-wave infrared signature of greenhouse gasses, enabling aerial detection and measurement of greenhouse gas sources via a single filtered image, which can drastically improve the speed and accuracy of monitoring greenhouse gas emissions. In the long-wave infrared regime, this research explores a four-color imaging thermometer, capitalizing on the resolution provided by four spectral bands—in conjunction with the TeX-Vision temperature-estimation algorithm—to yield unprecedented temperature estimation accuracy that can advance current medical diagnostic practices.The examples described in this thesis reveal the breadth of untapped information that is present in thermal radiation, which carries the ability to enhance the way we perceive our surroundings.
One-loop divergences in massive gravity theory

description: The one-loop divergences are calculated for the recently proposed ghost-free version of massive gravity, where the action depends on both metric and external tensor field f. The non-polynomial structure of the massive term is reduced to a more standard form by means of auxiliary tensor field, which is settled on-shell after quantum calculations are performed. As one should expect, the counterterms do not reproduce the form of the classical action. Moreover, the result has the form of the power series in f.

description: Actomyosin networks are major structural components of the cell. They provide mechanical integrity and allow dynamic remodeling of eukaryotic cells, self-organizing into the diverse patterns essential for development. We provide a theoretical framework to investigate the intricate interplay between local force generation, network connectivity and collective action of molecular motors. This framework is capable of accommodating both regular and heterogeneous pattern formation, arrested coarsening and macroscopic contraction in a unified manner. We model the actomyosin system as a motorized cat's cradle consisting of a crosslinked network of nonlinear elastic filaments subjected to spatially anti-correlated motor kicks acting on motorized (fibril) crosslinks. The phase diagram suggests there can be arrested phase separation which provides a natural explanation for the aggregation and coalescence of actomyosin condensates. Simulation studies confirm the theoretical picture that a nonequilibrium many-body system driven by correlated motor kicks can behave as if it were at an effective equilibrium, but with modified interactions that account for the correlation of the motor driven motions of the actively bonded nodes. Regular aster patterns are observed both in Brownian dynamics simulations at effective equilibrium and in the complete stochastic simulations. The results show that large-scale contraction requires correlated kicking.

Bobcat (Lynx rufus) habitat selection and suitability assessment in southeast British Columbia
Creators: name: Apps, Clayton Dale
Publisher: name: Environmental Design

description: Bibliography: p. 111-129.
description: Spatial organization, juvenile dispersal, winter food habits, and winter habitat relationships were examined for bobcats (Lynx rufus) occurring near a range limit in southeast British Columbia. For the period 1990 - 95, resident male and female annual home range size (95% ADK) differed, averaging 199.1 km2 (n = 7) and 64.6 km2 (n = 5) respectively. Home ranges were smaller in winter than in summer for males, but did not differ for females. Annual spatial overlap among neighboring males was extensive, although temporal avoidance was evident. Juvenile males (n = 6) exhibited long-distance dispersal, whereas juvenile females (n = 3) did not. Examination of 70 carcasses collected from throughout the region during winter, 1990 - 95, indicated red squirrels (Tamiasciurus hudsonicus) to be consumed most frequently (52% of stomachs), followed by ungulates (26%), microtine rodents (11 %), and snowshoe hares (Lepus americanus) (7%). Both ungulate consumption and fat index were greater for adult males than adult females or kitten/juveniles. Fat index was lower during the most severe winter for adult females and kitten/juveniles, but not for adult males. Results relate to body size differences among cohorts. Winter selection for most habitat variables was evident at both landscape and stand levels. Bobcats selected terrain characterized by low elevations, moderate slopes, and a proximity to rocky outcrops. Affinity for forest cover attributes was also apparent, particularly mature, multi-layered stands dominated by Douglas-fir, with moderate canopy closure, and large average tree diameter. Variation in selection patterns was evident among individuals and between sexes. Sex-specific multivariate models of winter habitat selection were developed for the study area. Discriminant functions were consistent with univariate results, above, and provided good predictive ability. Applied across the study area using GIS, the models predict the probability that any site represents "winter habitat" for bobcats, and equate to winter habitat suitability. These models may serve as useful management tools, provided that underlying assumptions are recognized. Selectivity analyses for levels of habitat dispersion suggest that bobcats select landscapes that achieve at least 25% "winter habitat" distributed per 75 km². Long-term persistence of bobcats in this region will require habitat management at multiple scales, and recommendations are provided.

description: With the goal in mind of deriving a method to compute quantum corrections for the real-time evolution in quantum field theory, we analyze the problem from the perspective of the Wigner function. We argue that this provides the most natural way to justify and extend the classical approximation. A simple proposal is presented that can allow to give systematic quantum corrections to the evolution of expectation values and/or an estimate of the errors committed when using the classical approximation. The method is applied to the case of a few degrees of freedom and compared with other methods and with the exact quantum results. An analysis of the dependence of the numerical effort involved as a function of the number of variables is given, which allow us to be optimistic about its applicability in a quantum field theoretical context.

description: The particle approach to one-dimensional potential scattering is applied to non relativistic tunnelling between two, three and four identical barriers. We demonstrate as expected that the infinite sum of particle contributions yield the plane wave results. In particular, the existence of resonance/transparency for twin tunnelling in the wave limit is immediately obvious. The known resonances for three and four barriers are also derived. The transition from the wave limit to the particle limit is exhibit numerically.
