description: The mechanical properties of the so-called `super' carbon nanotubes (STs) are investigated using classical molecular dynamics simulations. The STs are built from single walled carbon nanotubes (SWCNTs) connected by Y-like junctions forming an ordered carbon nanotube network that is then rolled into a seamless cylinder. We observed that the ST behavior under tensile tests is similar to the one presented by fishing nets. This interesting behavior provides a way to vary the accessible channels to the inner parts of STs by applying external mechanical load. The Young's modulus is dependent on the ST chirality and it inversely varies with the ST radius. Smaller reduction of breaking strain values due to temperature increase is predicted for zigzag STs compared to SWCNTs. The results show that, for STs with radius ~ 5 nm, the junctions between the constituent SWCNTs play an important role on the fracture process. The Young's modulus and tensile strength were estimated for hierarchical higher-order STs using scaling laws related to the ST fractal dimension. The obtained mechanical properties suggest that STs may be used in the development of new porous, flexible, and high-strength materials.

An investigation into the experience of being a protagonist in a psychodrama
Creators: name: Martens, Marlyn Leslie
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to investigate the meaning of the psychodrama process as experienced by individuals who claim that it resulted in significant change. Using an existential-phenomenological approach, the study described the meaning of the experience for six adult co-researchers. The co-researchers were asked to describe their experiences before, during, and after their psychodramas. Two interviews were conducted and these were tape recorded and transcribed. The transcripts were analyzed and themes were formulated which were validated by the co-researchers and woven into an exhaustive description of the psychodrama experience. The exhaustive description was condensed into an essential structure. Both the exhaustive description and the essential structure were validated by all the co- researchers. The results support elements of both psychodrama and Gestalt theory, as well as current theories of group development. Implications for counselling and further research are discussed.

description: We present in this paper a Bayesian parameter estimation method for the analysis of interferometric gravitational wave observations of an inspiral of binary compact objects using data recorded simultaneously by a network of several interferometers at different sites. We consider neutron star or black hole inspirals that are modeled to 3.5 post-Newtonian (PN) order in phase and 2.5 PN in amplitude. Inference is facilitated using Markov chain Monte Carlo methods that are adapted in order to efficiently explore the particular parameter space. Examples are shown to illustrate how and what information about the different parameters can be derived from the data. This study uses simulated signals and data with noise characteristics that are assumed to be defined by the LIGO and Virgo detectors operating at their design sensitivities. Nine parameters are estimated, including those associated with the binary system, plus its location on the sky. We explain how this technique will be part of a detection pipeline for binary systems of compact objects with masses up to $20 \sunmass$, including cases where the ratio of the individual masses can be extreme.

Influence of reading and mathematics screening tests and student ages on academic achievement in a two year Canadian college nursing program
Creators: name: Wade, Spencer
Publisher: name: University of British Columbia
Year: 2011

description: Presently the Douglas College General Nursing Program screens its applicants with the Nelson-Denny Reading Test and the Stanford Diagnostic Math Test in the belief that those tests set appropiate standards for admission to the program. No research had been performed to validate this belief. This descriptive, exploratory study examined the available data to determine the influence of the screening tests on academic achievement. Since the literature documents the influence of demographic variables on academic achievement in nursing programs, the students' ages were also included in this study. The students' scores on the screening tests, and the students' ages, were correlated with their scores on six nursing academic scores in the first two semesters in the program. Canonical correlation analysis was performed on the same data to see if insight could be obtained about the interrelationships of the screening tests, the students ages, and academic achievement. The Pearson r correlations indicate that the influence of the screening tests was small to moderate on academic achievement in the individual courses, and that students' ages demonstrated the weakest correlation. Sub-test 3 of the Stanford Diagnostic Math test consistently correlated the highest with the academic course scores with only two exceptions, and in those cases it was the second highest correlate. The canonical correlation analysis demonstrates that there are two underlying linkages or dimensions between the two data sets. The first dimension demonstrates the dominance of the Stanford Diagnostic Math sub-tests in correlating with academic achievement. The second dimension is too weak to make assumptions about the relationship between the two data sets, but it does suggest that the students' ages influence academic achievement.

description: We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method and multiple grid resolutions up to 2048^3 points. Our numerical experiments describe non-magnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We discuss numerical resolution issues and demonstrate convergence, in a statistical sense, of the inertial range dynamics in simulations on grids larger than 512^3 points. The simulations allowed us to measure the absolute velocity scaling exponents for the first time. The inertial range velocity scaling in this strongly compressible regime deviates substantially from the incompressible Kolmogorov laws. The slope of the velocity power spectrum, for instance, is -1.95 compared to -5/3 in the incompressible case. The exponent of the third-order velocity structure function is 1.28, while in incompressible turbulence it is known to be unity. We propose a natural extension of Kolmogorov's phenomenology that takes into account compressibility by mixing the velocity and density statistics and preserves the Kolmogorov scaling of the power spectrum and structure functions of the density-weighted velocity v=ρ^{1/3}u. The low-order statistics of v appear to be invariant with respect to changes in the Mach number. For instance, at Mach 6 the slope of the power spectrum of v is -1.69, and the exponent of the third-order structure function of v is unity. We also directly measure the mass dimension of the "fractal" density distribution in the inertial subrange, D_m = 2.4, which is similar to the observed fractal dimension of molecular clouds and agrees well with the cascade phenomenology.

description: The role of microplastics (MPs) as a vector of chemicals is generally recognized: a wide range of micropollutants have been detected in MPs sampled in different environmental compartments, and, due to their ubiquitous distribution, they can be transferred through aquatic and terrestrial organisms into the food chain. Providing representative models is challenging due to the intrinsic dynamic evolution characterizing the natural phenomena, which cannot be adequately investigated in lab experiments. On the other side, simulation/prediction tools are strongly required because of the long time-scale characterizing the MPs’ persistence in the environment. This article provides a review of the updated literature on mechanistic models and predictive thermodynamic methods applied (or applicable), to describe the uptake/release processes of pollutants by MPs. Intrinsic and environmental factors influencing the process kinetics and the equilibrium distribution are discussed in detail. Mechanistic models and thermodynamic prediction methods are analyzed and their potentialities for application to MPs highlighted with specific examples. Finally, a critical analysis of the limitations related to the simplifying assumptions in modeling and to the representativeness of the lab-scale data is performed to evaluate their effects on the reliability of the predictions and to identify knowledge gaps and address future research needs.

description: Abstract

In the ever-evolving digital landscape, algorithms wield remarkable influence over the information we encounter and the choices we make. This research aims to establish a foundational study as a valuable resource for novice researchers delving into the fundamental concepts of algorithms. Specifically, our study focuses on three significant aspects of algorithms: fairness, bias, and their role in content recommendation. We believe that these aspects are inherently interconnected, and our goal is to elucidate this relationship. By offering an introduction to these key components, we aim to equip researchers with the knowledge necessary to delve deeper into each of these domains and contribute to the discourse on ethical and effective algorithm deployment in the digital landscape.
Women and risk-taking : the overlooked dimension
Creators: name: Templeman, Jane Elizabeth
Publisher: name: University of British Columbia
Year: 2011

description: This research was based on the premise that psychological research on risk-taking behaviour has emphasized a one-dimensional model of instrumentality and cognitive functioning derived from male experience. The central research question "How do women experience risk-taking?" was investigated by analyzing definitions and examples of personal risk described by 44 women, and by comparing relationships between subgroups assigned by occupation and by sex-role orientation. The findings indicated that women experienced risk-taking that spanned both dimensions of affiliation (connection to others) and instrumentality (attainment of personal goals). A new definition of risk-taking was proposed that incorporated elements of uncertainty, emotional involvement, loss, and a process of change. Women in traditional occupations described a similar number of affiliative and instrumental risks, while women in non-traditional occupations emphasized instrumental risks. It was observed that the opportunity and demand for risk-taking appeared related to social context and work activity. Significant differences were also found between women in traditional and non-traditional occupations with respect to sex-role orientation (from the Bern Sex-Role Inventory), employment status, income level, and number of children. No differences were found between sub-groups designated by occupation and by sex-role orientation with respect to estimates of risk-taking tendency from a self-estimate scale and the Choice Dilemmas Questionnaire. The results supported a critique of the Choice Dilemmas Questionnaire, citing an emphasis on instrumental and hypothetical risk-taking. Participants also reported that the CDQ was not relevant to their lives. The feminist approach encouraged active participation and evaluation by the women in the study. As a result, participants reported an increased understanding of themselves and of the process of risk-taking.
The relationship between sexual abuse and juvenile prostitution in females
Creators: name: Edney, Raymonde Janet
Publisher: name: University of British Columbia
Year: 2011

description: The relationship between sexual abuse and juvenile prostitution is explored through interviews with eight women who had had both of these experiences in their lives. Analysis of the narrative data identified both social-structural and intra-psychic factors that played a role in leading these sexual abuse survivors into juvenile prostitution. Social-structural factors are defined as the cultural and societal conditions within which children are raised and socialised and within which they must learn to function. The social-structural factors identified by this study were cultural factors, gender stereotyping, the family, the schools, social networks, social service agencies, employment opportunities, religious institutions, sexual abuse and entrance into prostitution. Social-structural factors affect the individual at the intra-psychic or psychological level. Intra-psychic factors identified here were alienation, identity and personal control. Sullivan's (1984) theory of critical interpretation was used to examine the limiting effects of the social structures on the lives, behavior and choices of these women. This research found that sexual abuse and the victims' responses to sexual abuse prepared and trained the young girls for prostitution. Further, alienation appeared to be a major determining factor that combined with the presence of sexual abuse influenced the outcome of juvenile prostitution. Finally, these young women found that their personal control was limited and restricted by the social structures that maintained social control.

description: To explore gym staff perspectives on the inclusion of people with disability in the gym setting. Semi-structured interviews were conducted with 16 staff at four urban gym facilities, exploring perspectives on disability inclusion. An interpretive descriptive approach was adopted with reflexive thematic analysis of interview data and subsequent mapping of themes to the socioecological model. Consistent with the socioecological model, the themes identified were “people with disability benefit from participation in gym settings” (personal); “positive interactions with people with disability” (interpersonal); “managing expectations of other gym users” (interpersonal); “inclusion is supported by a positive ethos, staff training and accessible facilities” (organisational); “people with disability lack awareness of inclusive exercise opportunities” (community); “desire to increase collaboration with healthcare professionals” (community); “access to transport can facilitate gym attendance” (community) and “local gym policy” (policy). Although an overall ethos of inclusion was apparent, areas identified for enhancement were: awareness of gym services in the community; inter-sectoral collaboration with healthcare and disability organisations; comprehensive disability inclusion training; transport systems and accessibility; engaging people with disability in gym service planning.

description: In this investigation, we have shown that the combination of deep learning, including natural language processing, and conformal prediction results in highly predictive and efficient temporal test set sentiment estimates for 12 categories of Amazon product reviews using either in-category predictions, i.e. the model and the test set are from the same review category or cross-category predictions, i.e. using a model of another review category for predicting the test set. The similar results from in- and cross-category predictions indicate high degree of generalizability across product review categories. The investigation also shows that the combination of deep learning and conformal prediction gracefully handles class imbalances without explicit class balancing measures.

Based also on the OPT we predict a new universality class in quantum chaos related to the metal-insulator transition and provide several examples. In low dimensions it is characterized by classical superdiffusion or a fractal spectrum, in higher dimensions it can also have a purely quantum origin as in the case of disordered systems. Our findings open the possibility of studying the metal insulator transition experimentally in a much broader type of systems.

description: In this paper we review the applicability of autofluorescent proteins for single-molecule imaging in biology. The photophysical characteristics of several mutants of the Green Fluorescent Protein (GFP) and those of DsRed are compared and critically discussed for their use in cellular biology. The alternative use of two-photon excitation at the single-molecule level or Fluorescence Correlation Spectroscopy is envisaged for the study of individual autofluorescent proteins. Single-molecule experiments performed in live cells using eGFP and preferably eYFP fusion proteins are reviewed. Finally, the first use at the single-molecule level of citrine, a more photostable variant of the eYFP is reported when fused to a receptor for neurotransmitter in live cells.

description: This research study sought to respond to the question; what is the meaning of the experience of the companion to a grieving person? This was accomplished through using a phenomenological method of research. The researcher was guided by dramatic form in creating a common story of the experience and its structural meanings. This study included three co-researchers, who were selected on the basis that they had each been a companion to a mother who had grieved the loss of her child through death. The co-researchers were Interviewed and asked to give detailed descriptions of their experience, which were taperecorded and transcribed, and the transcripts or protocols were analyzed by the researcher. A Phenomenological protocol analysis was used to extract meaning units and common themes from the three protocols. The themes were woven into an integrated narrative description, which was condensed into the essential structure or meaning of the experience. At each stage of the analysis, the researcher and co-researchers cooperated so that all the results were validated by the final interview. The results of the study included a list of twenty-four themes, a narrative description of the experience being investigated, and the essential structure, which presented the meaning of the experience as concisely as possible. It was posited in the discussion that the study had particular implications for practice.

description: Trafficking of glutamate receptors into and out of synapses is critically involved in the plasticity of excitatory synaptic transmission. Endocytosis and exocytosis of receptors have initially been thought to account alone for this trafficking. However, membrane proteins also traffic through surface lateral diffusion in the plasma membrane. We describe developments in electrophysiological and optical approaches that have allowed for the real time measurement of glutamate receptor surface trafficking in live neurons. These include (i) specific imaging of surface receptors using a pH sensitive fluorescent protein, (ii) design of a photoactivable drug to inactivate locally surface receptors and monitor electrophysiologically their recovery, and (iii)application of single molecule fluorescence microscopy to directly track the movement of individual surface receptors with nanometer resolution inside and outside synapses. Altogether, these approaches have demonstrated that glutamate receptors diffuse at high rates in the neuronal membrane and suggest a key role for surface diffusion in the regulation of receptor numbers at synapses.

description: We study the phase diagram of strongly interacting matter with three quark flavors at low and intermediate densities and non-zero temperatures in the framework of an NJL-type model with four-point interactions. At large densities, when the interactions are weak due to asymptotic freedom, quarks form loosely bound Cooper pairs. However, when the density decreases, interactions become stronger and quark Cooper pairs transform smoothly into tightly bound diquark molecules. We find that such molecules are stable at low density and temperature and that they dissociate above a temperature $T_{\rm diss}$ of the order of the chiral phase transition temperature $T_c \sim 170$ MeV. We also explore the conditions under which these molecules undergo Bose-Einstein condensation (BEC). We find that BEC is only possible if we increase the attractive interaction in the diquark channel to (probably unrealistically) large values.

description: In the last decade evidence has accumulated that small domains of 50-700 nm in diameter are located in the exoplasmic leaflet of the plasma membrane. Most of these domains supposedly consist of specific sets of lipids and proteins, and are believed to coordinate signal transduction cascades. Whether similar domains are also present in the cytoplasmic leaflet of the plasma membrane is unclear so far. To investigate the presence of cytoplasmic leaflet domains, the H-Ras membrane-targeting sequence was fused to the C-terminus of the enhanced yellow fluorescent protein. Using single-molecule fluorescence microscopy, trajectories of individual molecules diffusing in the cytoplasmic leaflet of the plasma membrane were recorded. From these trajectories, the diffusion of individual membrane-anchored enhanced yellow fluorescent protein molecules was studied in live cells on timescales from 5 to 200 ms. The results show that the diffusion of 30-40% of the molecules is constrained in domains with a typical size of 200 nm. Neither breakdown of actin nor cholesterol extraction changed the domain characteristics significantly, indicating that the observed domains may not be related to the membrane domains identified so far.

description: Curvaton reheating is studied in non-oscillatory (NO) models of inflation, with the aim to obtain bounds on the parameters of curvaton models and find out whether low scale inflation can be attained. Using a minimal curvaton model, it is found that the allowed parameter space is considerably larger than in the case of the usual oscillatory inflation models. In particular, inflation with Hubble scale as low as 1 TeV is comfortably allowed.

description: We investigate the effect on the U, B, V, Rc and Rj magnitudes of the removal of emission lines from a spectrum. We determined "Dm" corrections from the ratio of fluxes with and without emission lines, transmitted from the object through the photometric filter. An exact and a simplified approach for operative use were applied. The effect was demonstrated for classical symbiotic stars, symbiotic novae and the classical nova V1974 Cyg. It was found that about 20-30, 30-40, 10 and 26/20 percents of the observed flux in the U, B, V and Rc/Rj filter, respectively, is radiated in the emission lines of the investigated classical symbiotic stars. The largest effect was found for symbiotic novae (RR Tel and V1016 Cyg) and the classical nova V1974 Cyg at 210 days (in average of 74, 79, 56 and 66/60 percents). Examples for practical application are suggested.

description: We introduce a new, highly sensitive, and simple heterodyne optical method for imaging individual nonfluorescent nanoclusters and nanocrystals. A 2 order of magnitude improvement of the signal is achieved compared to previous methods. This allows for the unprecedented detection of individual small absorptive objects such as metallic clusters (of 67 atoms) or nonluminescent semiconductor nanocrystals. The measured signals are in agreement with a calculation based on the scattering field theory from a photothermal-induced modulated index of refraction profile around the nanoparticle.

description: In this paper we describe a Bayesian inference framework for analysis of data obtained by LISA. We set up a model for binary inspiral signals as defined for the Mock LISA Data Challenge 1.2 (MLDC), and implemented a Markov chain Monte Carlo (MCMC) algorithm to facilitate exploration and integration of the posterior distribution over the 9-dimensional parameter space. Here we present intermediate results showing how, using this method, information about the 9 parameters can be extracted from the data.

description: Tradução de leaflet do Projeto AGFORWARD - O grão-de-bico (Cicer arietinum L.) é valorizado como alimento de qualidade para o homem e, também, como uma excelente fonte de proteína na alimentação animal. É de fácil cultivo, requer pouca gestão e, no geral, tem custos de tratamento baixos. O seu valor monetário é elevado, permitindo aos agricultores obter um rendimento adicional considerável ao cultivar grão-debico entre as árvores. Uma das caraterísticas mais importantes do grão-de-bico é a sua baixa exigência em água. Esta baixa exigência torna-o ideal para cultivo intercalado com árvores de tolerância à seca semelhante, em ecossistemas mediterrâneos ou noutros igualmente secos. Outra característica importante é o facto de o grão-de-bico fornecer azoto ao solo através da relação das suas raízes com bactérias fixadoras de azoto livre. Isso beneficia o agricultor, ao reduzir os custos com fertilizações azotadas, protegendo o solo e a água da contaminação com azoto.

description: Trafficking of AMPA receptors in and out of synapses is crucial for synaptic plasticity. Previous studies have focused on the role of endo/exocytosis processes or that of lateral diffusion of extra-synaptic receptors. We have now directly imaged AMPAR movements inside and outside synapses of live neurons using single-molecule fluorescence microscopy. Inside individual synapses, we found immobile and mobile receptors, which display restricted diffusion. Extra-synaptic receptors display free diffusion. Receptors could also exchange between these membrane compartments through lateral diffusion. Glutamate application increased both receptor mobility inside synapses and the fraction of mobile receptors present in a juxtasynaptic region. Block of inhibitory transmission to favor excitatory synaptic activity induced a transient increase in the fraction of mobile receptors and a decrease in the proportion of juxtasynaptic receptors. Altogether, our data show that rapid exchange of receptors between a synaptic and extra-synaptic localization occurs through regulation of receptor diffusion inside synapses.
Minimum-error discrimination between mixed quantum states

description: We derive a general lower bound on the minimum-error probability for {\it ambiguous discrimination} between arbitrary $m$ mixed quantum states with given prior probabilities. When $m=2$, this bound is precisely the well-known Helstrom limit. Also, we give a general lower bound on the minimum-error probability for discriminating quantum operations. Then we further analyze how this lower bound is attainable for ambiguous discrimination of mixed quantum states by presenting necessary and sufficient conditions related to it. Furthermore, with a restricted condition, we work out a upper bound on the minimum-error probability for ambiguous discrimination of mixed quantum states. Therefore, some sufficient conditions are obtained for the minimum-error probability attaining this bound. Finally, under the condition of the minimum-error probability attaining this bound, we compare the minimum-error probability for {\it ambiguously} discriminating arbitrary $m$ mixed quantum states with the optimal failure probability for {\it unambiguously} discriminating the same states.
