description: Nuclear magnetic resonance is a promising experimental approach to search for ultra-light axion-like dark matter. Searches such as the cosmic axion spin-precession experiments (CASPEr) are ultimately limited by quantum-mechanical noise sources, in particular, spin-projection noise. We discuss how such fundamental limits can potentially be reached. We consider a circuit model of a magnetic resonance experiment and quantify three noise sources: spin-projection noise, thermal noise, and amplifier noise. Calculation of the total noise spectrum takes into account the modification of the circuit impedance by the presence of nuclear spins, as well as the circuit back-action on the spin ensemble. Suppression of the circuit back-action is especially important in order for the spin-projection noise limits of searches for axion-like dark matter to reach the quantum chromodynamic axion sensitivity.

description: No abstracts are to be cited without prior reference to the author.Size selection investigations were performed on experimental fishery in the Sound with experimental, multi-panel gillnets equipped with a broad range of stretched mesh sizes of 19, 21, 26, 27, 28, 29, and 34 mm targeting herring (Clupea harengus) and of 34, 55, 60 mm targeting cod (Gadus morhua). Each of the 20 experimental fishery surveys covered the Sound from Helsingor­Helsingborg (north) to Drogden-Klagshamn (south) during the autumn, winter and spring periods. There was high variability in catch sizes both between and within surveys. Selection parameters were estimated for each set within each survey using the method described by Millar and Holst (1997). Several uni-modal curves provided appropriate fits with only minor differences in log­likelihood when fitted by individual sets. A mixture of two normal scales (a bi-modal curve) did not show any improvements in fits or it resulted in unreasonable estimates. The overall best fits were achieved using an uni-modal normal scale. Almost all surveys showed a high between-set variation, which was accounted for when estimating the mean selectivity curves using the random effects model by Fryer (1991). The selectivity curves fitted to individual sets were compared with the selectivity curves fitted to the combined data sets. It was demonstrated that analysing combined data resulted in over-dispersion and bias in the selection parameters. Irregular time series of the estimates of the selectivity parameters over the investigation period indicated negative auto­correlation with a seasonal pattern. The extension of these seasons seems, however, to be more than one year, and further research is needed to understand this phenomena. Finally, population indices for the observed length classes were derived from the catch length frequencies and the estimated selectivity parameters.

description: On March 2004, Anshel, Anshel, Goldfeld, and Lemieux introduced the \emph{Algebraic Eraser} scheme for key agreement over an insecure channel, using a novel hybrid of infinite and finite noncommutative groups. They also introduced the \emph{Colored Burau Key Agreement Protocol (CBKAP)}, a concrete realization of this scheme. We present general, efficient heuristic algorithms, which extract the shared key out of the public information provided by CBKAP. These algorithms are, according to heuristic reasoning and according to massive experiments, successful for all sizes of the security parameters, assuming that the keys are chosen with standard distributions. Our methods come from probabilistic group theory (permutation group actions and expander graphs). In particular, we provide a simple algorithm for finding short expressions of permutations in $S_n$, as products of given random permutations. Heuristically, our algorithm gives expressions of length $O(n^2\log n)$, in time and space $O(n^3)$. Moreover, this is provable from \emph{the Minimal Cycle Conjecture}, a simply stated hypothesis concerning the uniform distribution on $S_n$. Experiments show that the constants in these estimations are small. This is the first practical algorithm for this problem for $n\ge 256$. Remark: \emph{Algebraic Eraser} is a trademark of SecureRF. The variant of CBKAP actually implemented by SecureRF uses proprietary distributions, and thus our results do not imply its vulnerability. See also arXiv:abs/12020598

description: Context. Stellar spectral synthesis is essential for various applications, ranging from determining stellar parameters to comprehensive stellar variability calculations. New observational resources as well as advanced stellar atmosphere modelling, taking three dimensional (3D) effects from radiative magnetohydrodynamics calculations into account, require a more efficient radiative transfer. Aims. For accurate, fast and flexible calculations of opacity distribution functions (ODFs), stellar atmospheres and stellar spectra we developed an efficient code building on the well-established ATLAS9 code. The new code also paves the way for an easy and fast access to different elemental compositions in stellar calculations. Methods. For the generation of ODF tables we further developed the well-established DFSYNTHE code by implementing additional functionality, and a speed-up by employing a parallel computation scheme. In addition, the line lists used can be changed from Kurucz's recent lists. In particular, we implemented the VALD3 line list. Results. A new code, the Merged Parallelised Simplified ATLAS is presented. It combines the efficient generation of ODF, atmosphere modelling and spectral synthesis in local thermodynamic equilibrium, therefore being an all-in-one code. This all-in-one code provides more numerical functionality and is substantially faster compared to other available codes. The fully portable MPS-ATLAS code is validated against previous ATLAS9 calculations, the PHOENIX code calculations, and high quality observations.

description: We derive a formulation of mixed quantum-classical dynamics for describing electronic carriers interacting with phonons in reciprocal space. For dispersionless phonons, we start by expressing the real-space classical coordinates in terms of complex variables. A Fourier series over these coordinates then yields the reciprocal-space coordinates. Evaluating the electron-phonon interaction term through Ehrenfest's theorem, we arrive at a reciprocal-space formalism that is equivalent to mean-field mixed quantum-classical dynamics in real space. This equivalence is numerically verified for the Holstein and Peierls models, for which we find the reciprocal-space Hellmann-Feynman forces to involve momentum derivative contributions in addition to the position derivative terms commonly seen in real space. We close by presenting a proof of concept for the inexpensive modeling of low-momentum carriers interacting with phonons by means of a truncated basis in reciprocal space, which is not possible within a real space formulation.

description: We study the effects of unparticle physics in the pair productions of top quarks at the LHC and ILC. By considering vector, tensor and scalar unparticle operators, as appropriate, we compute the total cross sections for pair production processes depending on scale dimension $d_{\U}$. We find that the existence of unparticles would lead to measurable enhancements on the SM predictions at the LHC. In the case of ILC this may become two orders of magnitude larger than that of SM, for smaller values of $d_\U$, a very striking signal for unparticles.

description: No abstracts are to be cited without prior reference to the author.The use of spawning stock biomass as a measure of potential egg production in fish populations assumes that these two variables are related in a consistent way and that eggs produced by all females have equal probabilities of surviving. We conducted sensitivity analyses of egg production estimates to natural variations in population structure and reproductive biology, including the influence of female traits on egg and larval characteristics. Uncoupling between population egg production and spawning stock biomass left up to 25% of the variation in modelled egg production unexplained for cod in the central Baltic Sea (ICES Subdivisions 25-32). Correlated as well as random variations in model input parameters contributed to this uncoupling. Resolving egg production spatially (by subdivision) showed that in some years substantial fractions (up to 75%) of the total annual egg production were lost (in terms of recruit production) because eggs were exposed to sub-optimal hydrographic (oxygen) concentrations. We conclude that estimates of reproductive effort can be substantially improved with higher resolution information and that inconsistencies between egg production and spawning stock biomass likely confound attempts to isolate the causes ofrecruitment fluctuations.

Searching for Magnetic Monopoles with the Earth's Magnetic Field

description: Magnetic monopoles have long been predicted in theory and could exist as a stable object in our universe. As they move around in galaxies, magnetic monopoles could be captured by astrophysical objects like stars and planets. Here, we provide a novel method to search for magnetic monopoles by detecting the monopole moment of the Earth's magnetic field. Using over six years of public geomagnetic field data obtained by the Swarm satellites, we apply Gauss's law to measure the total magnetic flux, which is proportional to the total magnetic charge inside the Earth. To account for the secular variation of satellite altitudes, we define an altitude-rescaled magnetic flux to reduce the dominant magnetic dipole contribution. The measured magnetic flux is consistent with the existing magnetic field model that does not contain a monopole moment term. We therefore set an upper limit on the magnetic field strength at Earth's surface from magnetic monopoles to be $|B_{\rm m}| < 0.13$ nT at 95% confidence level, which is less than $2\times 10^{-6}$ of Earth's magnetic field strength. This constrains the abundance of magnetically-charged objects, including magnetic black holes with large magnetic charges.

Engagement with literature through writing : examining the ongoing written responses of adolescents
Creators: name: Kooy, Mary
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the written responses of seven adolescents to three novels. During the course of two school years, the students recorded their ongoing responses to small sections (ten to fifteen pages) of each novel in a response log. These responses were examined for evidence of patterns, typical responses, individual variations, and the effects of narrative structure. The Purves and Rippere instrument was used to determine response patterns while a new instrument developed by the researcher to accomodate the nature of the preliminary, ongoing responses was implemented to address the remaining three questions. The following general observations were made: 1. No predictable, sequential pattern of response could be found in student response writings. 2. Certain responses predominated: namely, narrational retelling, tentative frameworklng of the content, and analysis of characters and events 3. The written responses were generally characterized by considerable variation in individual responses. 4. Texts bearing distinct narrative features prompted different responses both for individuals and the group as a whole. Conclusions: The effects of writing during the reading of literary texts appears to bring response to a clear, conscious level. Writing in the response log encourages a conscious transaction with the literary text and consequently, readers can engage more actively and knowledgeably in the reading experience. Some broad conclusions and implications emerged from the study: 1. Particularly as they encounter complex literary works, adolescents should be encouraged to engage actively and consciously in their reading of literature by recording their ongoing responses in a log. 2. Teachers ought to promote the development of personal literary responses that require active thinking through testing hypotheses, making connections and interpreting the literary content 3. By purposefully structuring active meaning-making in the study of literature, teachers can determine the student needs and create the context for meaningful discussion. Moreover, by publicly sharing the contents of the response logs, all class members can contribute to and enhance their responses. Using writing to gauge the ongoing literary response allows both students and their teachers to be consciously aware of the "sense-making" strategies employed. As the medium for critical reading, writing promotes tentative, flexible construction of meaning. Furthermore, the instrument developed for analyzing the ongoing student responses in this study provides both a way to consciously examine the content of written responses and exposes alternative responses in order to extend understanding and appreciation of literature.

description: The subject of the present doctoral thesis is the mortgage based on a statutory title (legal mortgage). It focuses on the analysis of the statutory titles included in Article 1262 of the Greek Civil Code and the analysis of the main statutory titles provided in special laws. Research furthers upon the above-mentioned analysis and through it, it attempts to form general rules governing all cases of mortgages based on statutory provisions and cover the stages of acquisition, function and abolition of such rights. Following this direction, as a monograph, the thesis includes a comprehensive approach of the Civil Code mortgage provisions under the prism of mortgage based on a statutory title and it faces, in a systematic way, critical aspects related to it and, in general, related to property encumbrances.
A micro-analysis of collocation in the interlanguage of Pakistani adults learning English as a second language
Creators: name: Mian, A. Hafeez
Publisher: name: University of British Columbia
Year: 2010

description: A micro-analysis of the interlanguage (IL) employed by Pakistanis learning English as a second language (ESL) is performed on ten subjects' speech samples in order to gain insights into their second language acquisition. Only one aspect of ESL — collocation is studied. Collocation is idiomatic in nature and has single-lexemic function; it is assumed therefore to present some acquisitive and productive difficulties for second language learners, who would tend to fail to recognize collocations as "fixed" expressions and to view each word within them as independent and therefore replaceable. The objective of this study is to analyze the conversational collocation errors that Pakistani-Canadians make in ESL. This study addresses the following three hypotheses: 1) that in the English variation in collocation across discourse domains; speech of Pakistani subjects correctness will be found 2) that a continuum will be found for this variation, running between more Target-like collocations in the Work Talk Domain / Exposition Activity and fewer Target-like collocations in the Life Story Domain / Narrative Activity; 3) that formally educated subjects will show more Target-like use of collocations than informally educated subjects. The results of this study show that there exists an IL in Pakistani-Canadians' use of the English language. The IL of Pakistani-Canadians' English seems to indicate that: 1) IL collocations are domain specific; 2) Non-target-like collocations occur most often when referring to quantification; in T-unit initial position; and adjacent to parallel contextual and/or structural forms; and they often contain article ellipsis; 3) In addition, this study shows that formally educated subjects produce more Target-like collocations than informally educated subjects. Furthermore, this study has generated some questions and highlighted areas that merit further research.

description: This paper introduces an analytical method to calculate segment-level wavefront error tolerances in order to enable the detection of faint extra-solar planets using segmented telescopes in space. This study provides a full treatment of spatially uncorrelated segment phasing errors for segmented telescope coronagraphy, which has so far only been approached using ad hoc Monte-Carlo simulations. Instead of describing the wavefront tolerance globally for all segments, our method produces spatially dependent requirements. We relate the statistical mean contrast in the coronagraph dark hole to the standard deviation of the wavefront error of each individual segment on the primary mirror. This statistical framework for segment-level tolerancing extends the Pair-based Analytical model for Segmented Telescope Imaging from Space (PASTIS), which is based uniquely on a matrix multiplication for the optical propagation. We confirm our analytical results with Monte-Carlo simulations of E2E optical propagations through a coronagraph. Comparing our results for the Apodized Pupil Lyot Coronagraph designs for the Large UltraViolet Optical InfraRed (LUVOIR) telescope to previous studies, we show general agreement but provide a relaxation of the requirements for a significant subset of segments. These requirement maps are unique to any given telescope geometry and coronagraph design. The spatially uncorrelated segment tolerances we calculate are a key element of a complete error budget that will also need to include allocations for correlated segment contributions. We discuss how the PASTIS formalism can be extended to the spatially correlated case by deriving the statistical mean contrast and its variance for a non-diagonal aberration covariance matrix. The PASTIS tolerancing framework therefore brings a new capability that is necessary for the global tolerancing of future segmented space observatories.

description: We performed 121/123Sb-nuclear quadrupole resonance (NQR) measurements on the superconducting (SC) line-nodal material CaSb2 in order to investigate electronic properties in the normal and SC states from a microscopic point of view. In the normal state, the nuclear spin-lattice relaxation rate 1/T1 for the Sb(1) site, which is responsible for the line-nodal parts, is approximately proportional to temperature, indicating the conventional Fermi liquid state. From comparison with band structure calculations, it is considered that the NQR properties related to the line-nodal character are hidden because the conventional behavior originating from Fermi-surface parts away from the nodes is dominant. In the SC state, a clear coherence peak just below the transition temperature and an exponential decrease at lower temperatures were observed in 1/T1. These results strongly suggest that conventional s-wave superconductivity with a full gap is realized in CaSb2.

description: We present a study of 41 dwarf galaxies hosting active massive black holes (BHs) using Hubble Space Telescope observations. The host galaxies have stellar masses in the range of $M_\star \sim 10^{8.5}-10^{9.5}~M_\odot$ and were selected to host active galactic nuclei (AGNs) based on narrow emission line ratios derived from Sloan Digital Sky Survey spectroscopy. We find a wide range of morphologies in our sample including both regular and irregular dwarf galaxies. We fit the HST images of the regular galaxies using GALFIT and find that the majority are disk-dominated with small pseudobulges, although we do find a handful of bulge-like/elliptical dwarf galaxies. We also find an unresolved source of light in all of the regular galaxies, which may indicate the presence of a nuclear star cluster and/or the detection of AGN continuum. Three of the galaxies in our sample appear to be Magellanic-type dwarf irregulars and two galaxies exhibit clear signatures of interactions/mergers. This work demonstrates the diverse nature of dwarf galaxies hosting optically-selected AGNs. It also has implications for constraining the origin of the first BH seeds using the local BH occupation fraction at low masses -- we must account for the various types of dwarf galaxies that may host BHs.

description: The study of hard-particle packings is of fundamental importance in physics, chemistry, cell biology, and discrete geometry. Much of the previous work on hard-particle packings concerns their densest possible arrangements. By contrast, we examine kinetic effects inevitably present in both numerical and experimental packing protocols. Specifically, we determine how changing the compression/shear rate of a two-dimensional packing of noncircular particles causes it to deviate from its densest possible configuration, which is always periodic. The adaptive shrinking cell (ASC) optimization scheme maximizes the packing fraction of a hard-particle packing by first applying random translations and rotations to the particles and then isotropically compressing and shearing the simulation box repeatedly until a possibly jammed state is reached. We use a stochastic implementation of the ASC optimization scheme to mimic different effective time scales by varying the number of particle moves between compressions/shears. We generate dense, effectively jammed, monodisperse, two-dimensional packings of obtuse scalene triangle, rhombus, curved triangle, lens, and "ice cream cone" (a semicircle grafted onto an isosceles triangle) shaped particles, with a wide range of packing fractions and degrees of order. To quantify these kinetic effects, we introduce the kinetic frustration index $K$, which measures the deviation of a packing from its maximum possible packing fraction. To investigate how kinetics affect short- and long-range ordering in these packings, we compute their spectral densities and characterize their contact networks. We find that kinetic effects are most significant when the particles have greater asphericity, less curvature, and less rotational symmetry. This work may be relevant to the design of laboratory packing protocols.

description: Everyone uses cosmetic products every day, regardless of their gender and age, economic or social status. The user, in order to benefit from the positive properties of cosmetics, it is adamant they have basic knowledge regarding the composition, production, application and functionality of cosmetics. Wrong or incomplete knowledge in those areas, can have a detrimental effect to the user’s health and well-being. By constructing and circulating a questionnaire, we will try to explore the views of different consumers’ groups. We will be addressing five different groups of people, differentiated by their Chemistry knowledge. The focus of the study is to determine the degree of connection between the misconceptions and the deficiencies / misunderstandings in the subject of Chemistry. Finally, some educational proposals will be made to contribute towards the solution of the given issue.

description: In this work, we investigate the strength and impact of ionised gas outflows within $z \sim 0.04$ MaNGA galaxies. We find evidence for outflows in 322 galaxies ($12\%$ of the analysed line-emitting sample), 185 of which show evidence for AGN activity. Most outflows are centrally concentrated with a spatial extent that scales sublinearly with $R_{\rm e}$. The incidence of outflows is enhanced at higher masses, central surface densities and deeper gravitational potentials, as well as at higher SFR and AGN luminosity. We quantify strong correlations between mass outflow rates and the mechanical drivers of the outflow of the form $\dot{M}_{\rm out} \propto \rm SFR^{0.97}$ and $\dot{M}_{\rm out} \propto L_{\rm AGN}^{0.55}$. We derive a master scaling relation describing the mass outflow rate of ionised gas as a function of $M_{\star}$, SFR, $R_{\rm e}$ and $L_{\rm AGN}$. Most of the observed winds are anticipated to act as galactic fountains, with the fraction of galaxies with escaping winds increasing with decreasing potential well depth. We further investigate the physical properties of the outflowing gas finding evidence for enhanced attenuation in the outflow, possibly due to metal-enriched winds, and higher excitation compared to the gas in the galactic disk. Given that the majority of previous studies have focused on more extreme systems with higher SFRs and/or more luminous AGN, our study provides a unique view of the non-gravitational gaseous motions within `typical' galaxies in the low-redshift Universe, where low-luminosity AGN and star formation contribute jointly to the observed outflow phenomenology.

Boson Mott insulators at finite temperatures

description: We discuss the finite temperature properties of ultracold bosons in optical lattices in the presence of an additional, smoothly varying potential, as in current experiments. Three regimes emerge in the phase diagram: a low-temperature Mott regime similar to the zero-temperature quantum phase, an intermediate regime where MI features persist, but where superfluidity is absent, and a thermal regime where features of the Mott insulator state have disappeared. We obtain the thermodynamic functions of the Mott phase in the latter cases. The results are used to estimate the temperatures achieved by adiabatic loading in current experiments. We point out the crucial role of the trapping potential in determining the final temperature, and suggest a scheme for further cooling by adiabatic decompression.
Toward an understanding of academically successful English as a second language students
Creators: name: Gentry, Lorna Edith
Publisher: name: University of British Columbia

description: Twenty-five ESL students who were identified by teachers as "academically successful", i.e. with at least a C average in their regular courses, were interviewed, using an open ended conversational approach. Informants shared their own perspectives on their ESL and regular classroom experiences, their perceptions about themselves as students and their strategies for success. They compared experiences in Canada and their native countries, and talked about their home background. They were encouraged to identify both strengths and problems in their education experiences, and to suggest changes in the schools to help themselves as well as less successful students. Data concluded that informants showed additive bilingualism, many use L1 to learn their academic work, and overwhelmingly they support ESL classes which they credit with fulfilling both academic and affective needs. Academic work in the home country transfers to subjects such as Math, but they express frustration with written assignments and essay questions in subjects with heavy language requirements. In general there is little involvement with native-speaking peers. Informants were found to be highly disciplined, with high future aspirations.

description: The recently discovered Indus stellar stream exhibits a diverse chemical signature compared to what is found for most other streams due to the abundances of two outlier stars, Indus$\_$0 and Indus$\_$13. Indus$\_$13, exhibits an extreme enhancement in rapid neutron-capture ($r$-)process elements with $\mathrm{[Eu/Fe]} = +1.81$. It thus provides direct evidence of the accreted nature of $r$-process enhanced stars. In this paper we present a detailed chemical analysis of the neutron-capture elements in Indus$\_$13, revealing the star to be slightly actinide poor. The other outlier, Indus$\_0$, displays a globular cluster-like signature with high N, Na, and Al abundances, while the rest of the Indus stars show abundances compatible with a dwarf galaxy origin. Hence, Indus$\_0$ provides the first chemical evidence of a fully disrupted dwarf containing a globular cluster. We use the chemical signature of the Indus stars to discuss the nature of the stream progenitor which was likely a chemically evolved system, with a mass somewhere in the range from Ursa Minor to Fornax.

description: In this work a method for statistical analysis of time series is proposed, which is used to obtain solutions to some classical problems of mathematical statistics under the only assumption that the process generating the data is stationary ergodic. Namely, three problems are considered: goodness-of-fit (or identity) testing, process classification, and the change point problem. For each of the problems a test is constructed that is asymptotically accurate for the case when the data is generated by stationary ergodic processes. The tests are based on empirical estimates of distributional distance.

description: Using general relativistic magnetohydrodynamic simulations of accreting black holes, we show that a suitable subtraction of the linear polarization per pixel from total intensity images can enhance the photon ring features. We find that the photon ring is typically a factor of $\simeq 2$ less polarized than the rest of the image. This is due to a combination of plasma and general relativistic effects, as well as magnetic turbulence. When there are no other persistently depolarized image features, adding the subtracted residuals over time results in a sharp image of the photon ring. We show that the method works well for sample, viable GRMHD models of Sgr A* and M87*, where measurements of the photon ring properties would provide new measurements of black hole mass and spin, and potentially allow for tests of the "no-hair" theorem of general relativity.

description: The aim of this article is to propose an account of morpho-syntactic and interpretive properties of possessives looked at from the point of view suggested by the interplay between contact systems with prenominal and postnominal possessives. Thus, we will begin with briefly presenting the minority Franco-Provençal language of Celle di San Vito in Apulia and its linguistic position. Subsequently, we will dwell on the nature of possessive relation and its treatment in the literature, also taking account of the suggestions coming from cross-linguistic considerations (Albanian). Next, the data of Celle and the possessive systems of Southern Italian and Franco-Provençal varieties will be provided and compared. The final section illustrates some proposals concerning different possessive structures, specifically with regard to the distribution of possessive elements and the interaction with the definite article.

Optimisation based algorithm for finding the action of cosmological phase transitions

description: We present the OptiBounce algorithm, a new and fast method for finding the bounce action for cosmological phase transitions. This is done by direct solution of the "reduced" minimisation problem proposed by Coleman, Glaser, and Martin. By using a new formula for the action, our method avoids the rescaling step used in other algorithms based on this formulation. The bounce path is represented using a pseudo-spectral Gauss-Legendre collocation scheme leading to a non-linear optimisation problem over the collocation coefficients. Efficient solution of this problem is enabled by recent advances in automatic differentiation, sparse matrix representation and large scale non-linear programming. The algorithm is optimised for finding nucleation temperatures by sharing model initialisation work between instances of the calculation when operating at different temperatures. We present numerical results on a range of potentials with up to 20 scalar fields, demonstrating O(1%) agreement with existing codes and highly favourable performance characteristics.
