description: The vapor-liquid-solid (VLS) method is considered a plausible technique for synthesizing germanium (Ge) nanostructures (e.g. nanowires), which have a broad range of applications due to their unique electronic properties and intrinsic compatibility with silicon. However, crystallization failures and material defects are still frequently observed in VLS processes, with insufficient understanding of their underlying mechanisms due to instrumental limitations for high-resolution in-situ characterizations. Employing an accurate interatomic potential well fitted to the gold-germanium (Au-Ge) phase diagram, we performed molecular dynamics simulations for a systematic investigation on the Au-catalyzed growth process of Ge crystals. From the simulations, relationships were established between the overall Ge growth rate and several main synthesis conditions, including substrate crystallographic orientation, temperature and Ge supersaturation in liquid. The dynamical behaviors of Ge atoms near the liquid-solid growing interface were captured, from which the atom surface stability and exchange rate were estimated for quantifying the atomistic details of the growth. These interface properties were further linked to the surface morphologies, to explain the observed orientation-dependent growing modes. This study sheds new lights into the understanding of the VLS growth mechanisms of Ge crystals, and provides scientific guidelines for designing innovative synthesis methods for similar nanomaterials.

description: Precision measurements of the vortex phase diagram in single crystals of the layered superconductor Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$ in oblique magnetic fields confirm the existence of a second phase transition, in addition to the usual first order vortex lattice melting line $H_{m}(T)$. The transition has a strong first order character, is accompanied by strong hysteresis, and intersects the melting line in a tricritical point ($H_{m}^{\perp}$, $H^{\parallel}_{cr}$). Its field dependence and the changing character of the melting line at the tricritical point strongly suggest that the ground state for magnetic fields closely aligned with the superconducting layers is a lattice of uniformly tilted vortex lines.

description: This thesis focuses on the design and analysis of four novel types of photonic crystal fibers, with tunable polarization properties. The first three types address fibers infiltrated with nematic liquid crystalline materials, which operate via index-, bandgap, or hybrid-guidance. The fourth one exploits the inscription of long-period gratings in photonic crystal fibers with high geometrical birefringence. The proposed fibers are proven to allow for both single-polarization and polarization-maintaining guidance, offering additionally the possibility of dynamical tuning of their polarization properties, either via the application of external electric fields, or the variation of the fiber's operation temperature

description: We present the XMM-LSS cluster catalogue corresponding to the CFHTLS D1 area. The list contains 13 spectroscopically confirmed, X-ray selected galaxy clusters over 0.8 deg2 to a redshift of unity and so constitutes the highest density sample of clusters to date. Cluster X-ray bolometric luminosities range from 0.03 to 5x10^{44} erg/s. In this study, we describe our catalogue construction procedure: from the detection of X-ray cluster candidates to the compilation of a spectroscopically confirmed cluster sample with an explicit selection function. The procedure further provides basic X-ray products such as cluster temperature, flux and luminosity. We detected slightly more clusters with a (0.5-2.0 keV) X-ray fluxes of >2x10^{-14} erg/s/cm^{-2} than we expected based on expectations from deep ROSAT surveys. We also present the Luminosity-Temperature relation for our 9 brightest objects possessing a reliable temperature determination. The slope is in good agreement with the local relation, yet compatible with a luminosity enhancement for the 0.15 < z< 0.35 objects having 1 < T < 2 keV, a population that the XMM-LSS is identifying systematically for the first time. The present study permits the compilation of cluster samples from XMM images whose selection biases are understood. This allows, in addition to studies of large-scale structure, the systematic investigation of cluster scaling law evolution, especially for low mass X-ray groups which constitute the bulk of our observed cluster population. All cluster ancillary data (images, profiles, spectra) are made available in electronic form via the XMM-LSS cluster database.

Is soft physics entropy driven?

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The soft physics, pT < 2 GeV/c, observables at both RHIC and the SPS have now been mapped out in quite specific detail. From these results there is mounting evidence that this regime is primarily driven by the multiplicity per unit rapidity, dNch/deta. This suggests that the entropy of the system alone is the underlying driving force for many of the global observables measured in heavy-ion collisions. That this is the case and there is an apparent independence on collision energy is surprising. I present the evidence for this multiplicity scaling and use it to make some extremely naive predictions for the soft sector results at the LHC.

description: We discuss a class of quantum Abraham models in which the N-particle spinor wave function of N electrons solves a Pauli respectively Schroedinger equation, featuring regularized classical electromagnetic potentials which solve the semi-relativistic Maxwell-Lorentz equations for regularized point charges, which move according to some de Broglie-Bohm law of quantum motion. Thus there is a feedback loop from the actual particle motions to the wave function. The electrons have a bare charge and positive bare mass different from their empirical charge and mass due to renormalization by the self-fields. In the classical limit the various models reduce to the Hamilton-Jacobi version of corresponding Abraham models of classical electron theory.

description: We present one-dimensional numerical simulations describing the behavior of solid matter exposed to subpicosecond near infrared pulsed laser radiation. We point out to the role of strong isochoric heating as a mechanism for producing highly non-equilibrium thermodynamic states. In the case of metals, the conditions of material ejection from the surface are discussed in a hydrodynamic context, allowing correlation of the thermodynamic features with ablation mechanisms. A convenient synthetic representation of the thermodynamic processes is presented, emphasizing different competitive pathways of material ejection. Based on the study of the relaxation and cooling processes which constrain the system to follow original thermodynamic paths, we establish that the metal surface can exhibit several kinds of phase evolution which can result in phase explosion or fragmentation. An estimation of the amount of material exceeding the specific energy required for melting is reported for copper and aluminum and a theoretical value of the limit-size of the recast material after ultrashort laser irradiation is determined. Ablation by mechanical fragmentation is also analysed and compared to experimental data for aluminum subjected to high tensile pressures and ultrafast loading rates. Spallation is expected to occur at the rear surface of the aluminum foils and a comparison with simulation results can determine a spall strength value related to high strain rates.

description: We generalize the results of Song-Zelditch on geodesics in spaces of Kahler metrics on toric varieties to harmonic maps of any compact Riemannian manifold with boundary into the space of Kahler metrics on a toric variety. We show that the harmonic map equation can always be solved and that such maps may be approximated in the C^2 topology by harmonic maps into the spaces of Bergman metrics. In particular, WZW maps, or equivalently solutions of a homogeneous Monge-Ampere equation on the product of the manifold with a Riemann surface with S^1 boundary admit such approximations. We also show that the Eells-Sampson flow on the space of Kahler potentials is transformed to the usual heat flow on the space of symplectic potentials under the Legendre transform.
Curriculum rhetoric and contemporary practice in the Bahamian primary school system
Creators: name: Davis, Linda Agatha
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the ‘intended’ curriculum and the processes of its translation into classroom practices. The ‘intended’ curriculum is the rhetoric incorporated in state documents of the independence era in The Bahamas. These state documents included three key general educational policy documents in which policy makers presented persuasive arguments and strategies for the nation’s development, and the curriculum guides based on these earlier policy documents. Since these documents represent the educational intentions and objectives of the nation, it was assumed that an examination of their rhetoric would produce a portrait of the government’s ‘independence plan.’ However, because one cannot assume that rhetoric is translated into practice, this study also examined the extent to which teachers in the Bahamian Primary School System have translated this ‘independence plan’ into their contemporary practices. The methods of investigation included documentary analysis, participant observation, informal interviews with classroom teachers and other Ministry of Education officials, and a teacher questionnaire. The documentary analysis revealed a continuity of themes ran throughout the major educational documents. Foremost among these themes were the move toward the Bahamianisation of the educational system, the production of indigenous materials, the recognition of the classroom teacher as central in the reform process, and the importance of communication between policy makers and teachers. Field investigations revealed a divergency between the rhetoric of the educational policy documents and the practices within the contemporary educational context. The study identified five major factors that influence the success of the curriculum implementation process. These factors include resources, support services, the internal dynamics of the school context, assessment practices, and the personal backgrounds and professional experiences of teachers. The evidence reported in the study pointed to several components that would enhance success in the implementation of the intended curriculum. The question of resource availability, specifically resources of an indigenous nature, was the most significant issue uncovered by this study. In addition, the need for a more collaborative support network for teachers was evident. Finally, the study highlighted the importance of two components that are directly related to the formulation of policy. These include the need for policy makers to use teacher experience and insight, and be more cognizant of the factors that have an impact, both internally and externally, upon the school context.

description: In this paper, we present the results of the MitoEM challenge on mitochondria 3D instance segmentation from electron microscopy images, organized in conjunction with the IEEE-ISBI 2021 conference. Our benchmark dataset consists of two large-scale 3D volumes, one from human and one from rat cortex tissue, which are 1,986 times larger than previously used datasets. At the time of paper submission, 257 participants had registered for the challenge, 14 teams had submitted their results, and six teams participated in the challenge workshop. Here, we present eight top-performing approaches from the challenge participants, along with our own baseline strategies. Posterior to the challenge, annotation errors in the ground truth were corrected without altering the final ranking. Additionally, we present a retrospective evaluation of the scoring system which revealed that (1) the challenge metric was permissive with the false positive predictions and (2) the size-based grouping of instances did not correctly categorize mitochondria of interest. Thus, we propose a new scoring system that better reflects the correctness of the segmentation results. Although several of the top methods are compared favorably to our own baselines, substantial errors remain unsolved for mitochondria with challenging morphologies. Thus, the challenge remains open for submission and automatic evaluation, with all volumes available for download.

More specifically, we study data mining problems such as clustering and classification in data streams and we develop incremental algorith with low memory requirements. We examine similarity queries between different data streams and we propose an indexing scheme suitable for dynamic data. We also propose algorithms for continuous preference queries evaluation problems in sensor networks. We introduce queries for knowledge discovery and we propose algorithms for their evaluation

The social construction of gender in the practical arts
Creators: name: Eyre, Linda
Publisher: name: University of British Columbia
Year: 2008

description: This dissertation is a contribution to understanding the relationship between schooling and gender inequality. The study explores how gender as a social relation is organized and embedded in the daily experiences of classroom life and in the discourses of people who dwell there. The study deals with how classroom encounters contribute to the reproduction or transformation of gender categories and how students' and teachers' discursive practices build and support patriarchal structures. The study is grounded in critical education theory, feminist theory, and ethnographic research. The specific site for the study is the knowledge area described as the Practical Arts, namely home economics and technical studies. The research is limited to a single Grade 8, coeducational, home economics and technical studies program in an inner-city, multi-ethnic, secondary school in western Canada. Evidence is based on participant observation of classrooms, for one school year, with one group of students as they proceed through a combined home economics and technical studies program. Evidence is also obtained through interviews with students and teachers. The study illustrates how classroom practices support the patriarchal structures of division of labour, violence against women, and sexuality. The study shows how the students' and teachers' discursive practices produce girls and women, and less powerful boys, in subordinate positions and as objects of regulation. As well, students' previous experiences in domestic and technical work, and classroom discourse, produce and support the division of labour. The study shows how the conditions of teachers' work, their authoritarian, product oriented approach, and their powerful, institutional discourses grounded in biological and psychological development and equality of educational opportunity, prevent them from challenging patriarchal structures. Although the study shows how students and teachers are actively engaged in the production rather than the transformation of traditional gender relations, it also shows how patriarchy is incomplete: there were divisions within gender categories and there were many contradictions. The study shows how power relations are not static - they are constantly in process of negotiation, thereby opening possibilities for social change.

description: We analyze the two-player game of Knock 'em Down, asymptotically as the number of tokens to be knocked down becomes large. Optimal play requires mixed strategies with deviations of order sqrt(n) from the naive law-of-large numbers allocation. Upon rescaling by sqrt(n) and sending n to infinity, we show that optimal play's random deviations always have bounded support and have marginal distributions that are absolutely continuous with respect to Lebesgue measure.

Complementarity and Uncertainty in Mach-Zehnder Interferometry and beyond
Creators: name: Busch, Paul
name: Shilladay, Christopher R.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A coherent account of the connections and contrasts between the principles of com- plementarity and uncertainty is developed starting from a survey of the various formalizations of these principles. The conceptual analysis is illustrated by means of a set of experimental schemes based on Mach-Zehnder interferometry. In particu- lar, path detection via entanglement with a probe system and (quantitative) quan- tum erasure are exhibited to constitute instances of joint unsharp measurements of complementary pairs of physical quantities, path and interference observables. The analysis uses the representation of observables as positive-operator-valued measures (POVMs). The reconciliation of complementary experimental options in the sense of simultaneous unsharp preparations and measurements is expressed in terms of uncertainty relations of different kinds. The feature of complementarity, manifest in the present examples in the mutual exclusivity of path detection and interference observation, is recovered as a limit case from the appropriate uncertainty relation. It is noted that the complementarity and uncertainty principles are neither completely logically independent nor logical consequences of one another. Since entanglement is an instance of the uncertainty of quantum properties (of compound systems), it is moot to play out uncertainty and entanglement against each other as possible mechanisms enforcing complementarity.

description: We study noncommutative field theories, which are inherently nonlocal, using a Poincaré-invariant regularisation scheme which yields an effective, nonlocal theory for energies below a cut-off scale. After discussing the general features and the peculiar advantages of this regularisation scheme for theories defined in noncommutative spaces, we focus our attention onto the particular case when the noncommutativity parameter is inversely proportional to the square of the cut-off, via a dimensionless parameter $η$. We work out the perturbative corrections at one-loop order for a scalar theory with quartic interactions, where the signature of noncommutativity appears in $η$-dependent terms. The implications of this approach, which avoids the problems related to UV-IR mixing, are discussed from the perspective of the Wilson renormalisation program. Finally, we remark about the generality of the method, arguing that it may lead to phenomenologically relevant predictions, when applied to realistic field theories.

description: We calculate the effect of a Dirac point (a conical singularity in the band structure) on the transmission of monochromatic radiation through a photonic crystal. The transmission as a function of frequency has an extremum at the Dirac point, depending on the transparencies of the interfaces with free space. The extremal transmission $T_{0}=Γ_{0} W/L$ is inversely proportional to the longitudinal dimension $L$ of the crystal (for $L$ larger than the lattice constant and smaller than the transverse dimension $W$). The interface transparencies affect the proportionality constant $Γ_{0}$, and they determine whether the extremum is a minimum or a maximum, but they do not affect the ``pseudo-diffusive'' 1/L dependence of $T_{0}$.

description: We report the serendipitous discovery of the Sloan Digital Sky Survey star, SDSS J160043.6+074802.9 to be a very rapid pulsator. The variation is dominated by a frequency near 8380 microHz (period = 119.33 s) with a large amplitude (0.04 mag) and its first harmonic at 16760 microHz (59.66 s; 0.005 mag). In between these frequencies, we find at least another 8 variations with periods between 62 and 118 seconds and amplitudes between about 0.007 and 0.003 mag; weaker oscillations might also be present. Preliminary spectrograms from the performance verification phase of the Southern African Large Telescope indicate that SDSS J160043.6+074802.9 is a spectroscopic binary consisting of an sdO star and a late-type main-sequence companion. This makes it the first unambiguous detection of such an sdO star to pulsate, and certainly the first found to exhibit multi-frequency variations.

Although this problem can be easily explained in terms of rotating frames of references and standard Coriolis Effect, it is sometimes misunderstood by students and even by some physics textbooks. We also present a simple experimental activity which can be used as a demonstration of this peculiar kinematical effect in general physics courses, or become part of laboratory activities.

Curriculum development in community education : a theoretical study
Creators: name: Calliou, Sharilyn
Publisher: name: University of British Columbia
Year: 2008

description: This study was primarily designed to develop principles and evaluation criteria of curriculum in community education. Before these could be developed, it was necessary to reassess commonly well-known and accepted works of community education theorists in order to deduce generic features and, thusly, identify the means and ends envisioned by community educators. Community education can be defined as a hypothesis which attempts to explain a relationship where participants interact in certain ways and use particular methods in a location over time to achieve self-determined transformative change and social justice. Therefore, curriculum development in community education ought to mirror facets of this definition. In this study, curricular experiences would be designed to have these features: (1) community-based study which has an extra-community awareness; (2) lifelong teaching and learning; (3) proactive problem-solving; (4) educational activism; (5) participatory democracy; (6) intergenerational grouping; and, (7) egalitarianism.

description: Aims: We search for PAH features towards T Tauri stars and compare them with surveys of Herbig Ae/Be stars. The presence and strength of the PAH features are interpreted with disk radiative transfer models exploring the PAH feature dependence on the incident UV radiation, PAH abundance and disk parameters. Methods: Spitzer Space Telescope 5-35 micron spectra of 54 pre-main sequence stars with disks were obtained, consisting of 38 T Tauri, 7 Herbig Ae/Be and 9 stars with unknown spectral type. Results: Compact PAH emission is detected towards at least 8 sources of which 5 are Herbig Ae/Be stars. The 11.2 micron PAH feature is detected in all of these sources, as is the 6.2 micron PAH feature where short wavelength data are available. However, the 7.7 and 8.6 micron features appear strongly in only 1 of these 4 sources. PAH emission is observed towards at least 3 T Tauri stars (8% detection rate). The lowest mass source with PAHs in our sample is T Cha (G8). All 4 sources in our sample with evidence for dust holes in their inner disk show PAH emission, increasing the feature/continuum ratio. Typical 11.2 micron line intensities are an order of magnitude lower than those observed for the more massive Herbig Ae/Be stars. Measured line fluxes indicate PAH abundances that are factors of 10-100 lower than standard interstellar values. Conversely, PAH features from disks exposed to stars with Teff<=4200K without enhanced UV are predicted to be below the current detection limit, even for high PAH abundances. Disk modeling shows that the 6.2 and 11.2 micron features are the best PAH tracers for T Tauri stars, whereas the 7.7 and 8.6 micron bands have low feature over continuum ratios due to the strongly rising silicate emission.

description: We investigate and compute spectral sums of the Wilson lattice Dirac operator for quenched SU(3) gauge theory. It is demonstrated that there exist sums which serve as order parameters for the confinement-deconfinement phase transition and get their main contribution from the IR end of the spectrum. They are approximately proportional to the Polyakov loop. In contrast to earlier studied spectral sums some of them are expected to have a well-defined continuum limit.
