description: This paper presents a cognitive typology of reuse processes, and a cognitive typology of documenting processes. Empirical studies on design with reuse and on software documenting provide evidence for a generalized cognitive model. First, these studies emphasize the cyclical nature of design: cycles of planning, writing and revising occur. Second, natural language documentation follows the hierarchy of cognitive entities manipulated during design. Similarly software reuse involves exploiting various types of knowledge depending on the phase of design in which reuse is involved. We suggest that these observations can be explained based on cognitive models of text processing: the van Dijk and Kintsch (1983) model of text comprehension, and the Hayes and Flower (1980) model of text production. Based on our generalized cognitive model, we suggest a framework for documenting reusable components.

description: Dispersion, impedance matching and resolution characteristics of an isotropic three-dimensional flat lens ("superlens") are studied. The lens is based on cubic meshes of interconnected transmission lines and bulk loads. We study a practical realization of the lens, based on the microstrip technology. The dispersion equations that have been previously derived, are verified with full-wave simulations. The isotropy of the structure is verified with analytical as well as simulation results. The resolution characteristics of a practically realizable, lossy lens are studied analytically.

The experience of making a career decision in young adulthood
Creators: name: Breuer, Karin
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to examine how young adults frame the experience of making a career decision. Eight persons between the ages of 18 and 25 years, who were enrolled in a post secondary program which on completion could lead directly into an occupation, volunteered to take part in the study. Participants completed a brief demographic questionnaire and were interviewed twice. The narratives were transcribed and then analyzed using a phenomenological method (Giorgi, 1975; Gurwitsch, 1968). Independent elements of the stories, called meaning units (Giorgi, 1975), were identified and sorted into 40 theme clusters that reflected the young adults' experience of making career decisions. The theme clusters were collapsed into 11 categories representing the noematic nucleus (Gurwitsch, 1968), which lead to the structure of the experience: the relationship of self in deciding, volition, the experience of high school, outside influences, the role of family, applying to a program, feelings about being accepted, observation about others, self-talk, other decisions, and thoughts about the future. The narratives were then re-read and two questions were asked: "What does this statement tell us about the experience?" and "How is the statement framed?". It was found that young adults respond to personal stimulus that activates the career decision process. Application to a post secondary program was seen as synonymous with commitment to a career path. The anxiety of waiting, was followed by a feeling of freedom and empowerment when the individual had been accepted to the program of choice. The experience was marked by strong emotions, self-knowledge, and a stated as well as tacit understanding of the environmental factors that influenced the decision. The study illustrates the need for practitioners to examine their modes of, as well as their expected outcomes for career counselling. The young adults interviewed expressed varying levels of dissatisfaction with the career counselling they received in school. They were articulate about what might have helped them and tended to believe that drifting into a career was equally valid as making a career choice.

description: Problème En Béarn, la monoculture du maïs est le système de culture le plus répandu. Or, ce système doit faire face au risque de volatilité des prix ainsi qu'à l'évolution de la réglementation de la Politique Agricole Commune (PAC), qui impose notamment la diversification des rotations. Outre les aspects agronomiques, la rentabilité peut également être améliorée par la valorisation de la période d'interculture. Dans le système actuel, le sol est laissé à nu. Solution En alternative à la monoculture du maïs, il a été mis en place un système innovant permettant de récolter deux cultures dans l'année au lieu d'une. Il est basé sur l'introduction de l'avoine comme culture intermédiaire à fin énergétique (CIVE) destinée à être valorisée en méthaniseur. Ce système a montré une amélioration des performances agronomiques, économiques et environnementales.

description: Energy Efficiency in wireless sensor networks is an important topic in which the nodes rely on battery power, and efficient energy usage is a key issue for sensitive applications that require long working times. This stimulates many scientists at all levels of communication protocols Medium Access Control (MAC) who control the use of the wireless transmitter and receiver unit to create new protocols. Many protocols were suggested that primarily take energy efficiency as the primary objective of sustaining the function of the network for as long as possible into account with different objectives for wireless sensor networks. This paper will look at some of these energy efficiency protocols.

description: The temporal Talbot effect refers to the periodic revivals of a pulse train propagating in a dispersive medium, and is a temporal analog of the spatial Talbot effect with group-velocity dispersion in time replacing diffraction in space. Because of typically large temporal Talbot lengths, this effect has been observed to date in only single-mode fibers, rather than with freely propagating fields in bulk dispersive media. Here we demonstrate for the first time the temporal Talbot effect in free space by employing dispersive space-time wave packets, whose spatio-temporal structure induces group-velocity dispersion of controllable magnitude and sign in free space.

description: We present a refined orbital solution for the components A, B, and C of the nearby late-M type multiple system LHS 1070. By combining astrometric datapoints from NACO/VLT, CIAO/SUBARU, and PUEO/CFHT, as well as a radial velocity measurement from the newly commissioned near infrared high-resolution spectrograph CRIRES/VLT, we achieve a very precise orbital solution for the B and C components and a first realistic constraint on the much longer orbit of the A-BC system. Both orbits appear to be co-planar. Masses for the B and C components calculated from the new orbital solution (M_(B+C) = 0.157 +/- 0.009 M_sun) are in excellent agreement with theoretical models, but do not match empirical mass-luminosity tracks. The preliminary orbit of the A-BC system reveals no mass excess for the A component, giving no indication for a previously proposed fourth (D) component in LHS 1070.

Burial of the polar magnetic field of an accreting neutron star. II. Hydromagnetic stability of axisymmetric equilibria

description: The theory of polar magnetic burial in accreting neutron stars predicts that a mountain of accreted material accumulates at the magnetic poles of the star, and that, as the mountain spreads equatorward, it is confined by, and compresses, the equatorial magnetic field. Here, we extend previous, axisymmetric, Grad-Shafranov calculations of the hydromagnetic structure of a magnetic mountain up to accreted masses as high as $\Ma = 6\times 10^{-4}\Msun$, by importing the output from previous calculations (which were limited by numerical problems and the formation of closed bubbles to $\Ma < 10^{-4}\Msun$) into the time-dependent, ideal-magnetohydrodynamic code ZEUS-3D and loading additional mass onto the star dynamically. The rise of buoyant magnetic bubbles through the accreted layer is observed in these experiments. We also investigate the stability of the resulting hydromagnetic equilibria by perturbing them in ZEUS-3D. Surprisingly, it is observed that the equilibria are marginally stable for all $\Ma\leq 6\times 10^{-4}\Msun$; the mountain oscillates persistently when perturbed, in a combination of Alfvén and acoustic modes, without appreciable damping or growth, and is therefore not disrupted (apart from a transient Parker instability initially, which expels $< 1 %$ of the mass and magnetic flux).

description: Deficit of attention, anxiety, sleep disorders are some of the problems which affect many persons. As these issues can evolve into severe conditions, more factors should be taken into consideration. The paper proposes a conception which aims to help students to enhance their brain performance. An electrocephalogram headset is used to trigger the brainwaves, along with a web application which manages the input data which comes from the headset and from the user. Factors like current activity, mood, focus, stress, relaxation, engagement, excitement and interest are provided in numerical format through the use of the headset. The users offer information about their activities related to relaxation, listening to music, watching a movie, and studying. Based on the analysis, it was found that the users consider the application easy to use. As the users are more equilibrated emotionally, their results are improved. This allowed the persons to be more confident on themselves. In the case of students, the neurofeedback can be studied for the better sport and artistic performances, including the case of the attention deficit hyperactivity disorder. Aptitudes for a subject can be determined based on the relevant generated brainwaves. The learning environment is an important factor during the analysis of the results. Teachers, professors, students and parents can collaborate and, based on the gathered data, new teaching methods can be adopted in the classroom and at home. The proposed solution can guide the students while studying, as well as the persons who wish to be more productive while solving their tasks.

description: We study the transport properties of model networks such as scale-free and Erdős-Rényi networks as well as a real network. We consider the conductance $G$ between two arbitrarily chosen nodes where each link has the same unit resistance. Our theoretical analysis for scale-free networks predicts a broad range of values of $G$, with a power-law tail distribution $Φ_{\rm SF}(G)\sim G^{-g_G}$, where $g_G=2λ-1$, and $λ$ is the decay exponent for the scale-free network degree distribution. We confirm our predictions by large scale simulations. The power-law tail in $Φ_{\rm SF}(G)$ leads to large values of $G$, thereby significantly improving the transport in scale-free networks, compared to Erdős-Rényi networks where the tail of the conductivity distribution decays exponentially. We develop a simple physical picture of the transport to account for the results. We study another model for transport, the \emph{max-flow} model, where conductance is defined as the number of link-independent paths between the two nodes, and find that a similar picture holds. The effects of distance on the value of conductance are considered for both models, and some differences emerge. We then extend our study to the case of multiple sources, where the transport is define between two \emph{groups} of nodes. We find a fundamental difference between the two forms of flow when considering the quality of the transport with respect to the number of sources, and find an optimal number of sources, or users, for the max-flow case. A qualitative (and partially quantitative) explanation is also given.

description: In resonantly pumped polariton superfluids we recently explored a new regime based on the bistability of the polariton system to enhance the propagation of polariton fluids up to macroscopic distances. This technique together with an all-optical imprinting method allowed the generation and control of various topological excitations such as quantized vortices and dark solitons. The flexibility and scalability of the new experimental scheme opens the way to the systematic study of quantum turbulence in driven dissipative quantum fluids of light. In this article we review the basic working principles of the bistability enhanced propagation and of the imprinting technique and we discuss the main achieved results as well as the most promising future research directions.

description: We study the implementation of the type III seesaw in the ordinary nonsupersymmetric SU(5) grand unified theory. This allows for an alternative definition of the minimal SU(5) model, with the inclusion of the adjoint fermionic multiplet. The main prediction of the theory is the light fermionic SU(2) triplet with mass at the electroweak scale. Due to their gauge couplings, these triplets can be produced pair-wise via Drell-Yan, and due to the Majorana nature of the neutral component their decays leave a clear signature of same sign di-leptons and four jets. This allows for their possible discovery at LHC and provides an example of directly measurable seesaw parameters.

description: The effects of initial-state Coulomb interactions in the charge-symmetry-breaking reaction dd -> alpha pi^0 are investigated within a previously published formalism. This is a leading order effect in which the Coulomb interaction between the two initial state protons leads to the breakup of the two deuterons into a continuum state that is well connected to the final alpha pi^0 state by the strong emission of a pion. As a first step, we use a simplified set of d and alpha wave functions and a plane-wave approximation for the initial dd state. This Coulomb mechanism, by itself, yields cross sections that are much larger than the experimental ones, and which are comparable in size to the contributions from other mechanisms. Inclusion of this mechanism is therefore necessary in a realistic calculation.

A new, Gaia based, catalogue of blue straggler stars in open clusters

description: Blue straggler stars are exotic objects present in all stellar environments whose nature and formation channels are still partially unclear. They seem to be particularly abundant in open clusters (OCs), thus offering a unique chance to tackle these problems statistically.We aim to build up a new and homogeneous catalogue of blue straggler stars (BSS) in Galactic OCs using Gaia to provide a more solid assessment of the membership of these stars. We also aim to explore possible relationships of the straggler abundance with the parent cluster's structural and dynamical parameters. As a by-product, we also search for possible yellow straggler stars (YSS), which are believed to be stragglers in a more advanced evolution stage. We employed photometry, proper motions, and parallaxes extracted from Gaia DR2 for 408 Galactic star clusters and searched for stragglers within them after performing a careful membership analysis. The number of BBS emerging from our more stringent, selection criteria turns out to be significantly smaller than in previous versions of this catalogue. OCs are therefore not a preferable environment for these kinds of stars anymore. In addition, we found that BSS start to appear in clusters with ages larger than log(t) ~ 8.7 and are therefore absent in very young star clusters.The present catalogue supersedes the previous ones in several ways: membership assessment, number of stragglers found, and so forth. The new list includes 897 BSS and 77 YSS candidates in 408 OCs. We expect this catalogue to be the basis for a new round of studies of BSS and YSS.

description: An Intelligent IoT Environment (iIoTe) is comprised of heterogeneous devices that can collaboratively execute semi-autonomous IoT applications, examples of which include highly automated manufacturing cells or autonomously interacting harvesting machines. Energy efficiency is key in such edge environments, since they are often based on an infrastructure that consists of wireless and battery-run devices, e.g., e-tractors, drones, Automated Guided Vehicle (AGV)s and robots. The total energy consumption draws contributions from multipleiIoTe technologies that enable edge computing and communication, distributed learning, as well as distributed ledgers and smart contracts. This paper provides a state-of-the-art overview of these technologies and illustrates their functionality and performance, with special attention to the tradeoff among resources, latency, privacy and energy consumption. Finally, the paper provides a vision for integrating these enabling technologies in energy-efficient iIoTe and a roadmap to address the open research challenges

description: Hexagonal warping (HW) in three-dimensional topological insulators is, by now, well-known. We show that non-Hermitian (NH) loss/gain can generate an exceptional HW effect in double Weyl-semimetals (DWSM). This unique feature of DWSMs has distinctive effects on Fermi surface topology. Importantly, in the presence of such a $k^3$ spin orbit coupling mimicking term, the symmetry associated with the DWSMs is changed, leading to four exceptional points, among which two are degenerate. Introducing a driving field removes this degeneracy. The combined action of the NH warping and driving parameters leads to notable effects, including merging and tuning of exceptional points. We analyze the topological nature of the generated exceptional contours by evaluating several topological invariants, such as winding number, vorticity, and NH Berry curvature. We hope that our theoretical results would initiate possible experiments exploring NH HW effects.

description: The SL(3,C)-representation variety R of a free group F arises naturally by considering surface group representations for a surface with boundary. There is a SL(3,C)-action on the coordinate ring of R by conjugation. The geometric points of the subring of invariants of this action is an affine variety X. The points of X parametrize isomorphism classes of completely reducible representations. We show the coordinate ring C[X] is a complex Poisson algebra with respect to a presentation of F imposed by the surface. Lastly, we work out the bracket on all generators when the surface is a three-holed sphere or a one-holed torus.

We define the "sharp de Rham realization" by passing to the Lie-algebra. Over the complex numbers we then show a (sharp de Rham) comparison theorem in the category of formal Hodge structures. For a free 1-motive along with its Cartier dual we get a canonical connection on their sharp extensions yielding a perfect pairing on sharp realizations. We thus provide "one-dimensional sharp de Rham cohomology" of algebraic varieties.

Management of breast cancer pain in the home setting : a patient perspective
Creators: name: Bartlett, Katharine Gail
Publisher: name: University of British Columbia
Year: 2010

description: This study's purpose was to describe, from their own perspective, the experience of individuals coping with metastatic breast cancer-related pain at home. Understanding how individuals cope on a day-to-day basis, in their natural setting, is essential in order to facilitate effective management of cancer pain in the home setting. Using a qualitative approach and multiple case study design, data was collected by means of unstructured, in-depth interviews with six female co-researchers. All interviews were audiotaped and transcribed verbatim. Transcripts and field notes were analyzed for common themes, which were then reconstructed into a case study format and validated by the co-researchers. Finally, co-researcher accounts were integrated into one coherent description. This study adds an extensive description to existing literature, providing an explicit portrayal of the experiences lived by these women. There were many commonalities in their stories, yet each person's story was unique, with each woman managing cancer pain in their own way. This study suggests that women did not commonly achieve adequate pain relief through the use of medications. A multitude of factors, including the severity of medication side effects, influenced their decisions not to take increased doses of pain medications. However, women acted from a position of choice by electing to tolerate pain in order to maintain control of the life they valued. This study leaves little doubt that the impact of pain related to breast cancer is potentially devastating to a life. The challenge of describing and managing cancer pain effectively continues to be a serious problem for both professionals and individuals coping with breast cancer-related pain.

Light is trapped in the vicinity of the boundary of the array due to the interplay between the repulsive edge potential and Bragg reflection inside the array. In the special case when this potential is linear these oscillations reduce themselves to surface Bloch oscillations.

description: One of the most severe peel physiological disorders of orange fruits is Stem End Rind Breakdown (SERB), a severe postharvest physiological disorder. We expected foliar Ca and K application to reduce orange SERB by modifying several peel biochemical and physical characteristics. Therefore, one experiment (2018–2020) was designed in complete randomized blocks in four treatments with three replicates. Experimental treatments included foliar spray of (1) K nitrate; (2) Ca nitrate; (3) Ca, and K nitrate separately, with a time interval (Ca + K; combination of treatments 1 and 2); (4) control. The effects of treatments were evaluated on several parameters underlying fruit peel quality at harvest and intensity of SERB damage after 12 wk of fruit storage at 5 ◦C and 85% RH. The results showed that K-treated fruits had higher TSS and TSS/TA than other fruits. Also, the Ca treatments (including Ca and Ca + K treatments) increased Ca content in fruit peels and significantly decreased SERB damage and weight loss by 70% and 30%, respectively. In addition, Thomson orange peel obtained from Ca-treated trees (including Ca and Ca + K treatments) displayed elevated levels of pectin than other fruits. In contrast, the peels of fruits picked from trees sprayed with Ca, especially those treated with Ca + K, exhibited lower levels of total phenolic, antioxidant, and electrolyte leakage than other fruits. This study suggests that foliar application of Ca(NO3)2 and KNO3 during the fruit growth cycle while improving the internal quality of the fruit is an effective agronomical strategy that prolongs Thomson orange shelf life.

Unconscious communication of children in psychotherapy : analysis of sessions with respect to variables pertaining to Langsian ground rules of psychotherapeutic relationship
Creators: name: Bonac, Vesna A.
Publisher: name: University of British Columbia
Year: 2010

description: The central thesis of this study says that the ground rules and boundaries of the psychotherapeutic relationship (the frame), as defined by Robert Langs for adults and adolescents, are the same for children. Transcripts from memory of verbalisation and behaviours from 12 sessions of children in individual psychotherapy were analyzed with the purpose to test Langsian communicative psychoanalytic hypotheses. Unconscious communications were analyzed in accordance with Langs' theories to determine the impact of the state of the frame on children. The dependent variable, unconscious communication, was analyzed with respect to the following nine independent variables of the frame: (a) change in therapy rooms, (b) audio recording of session, (c) missed sessions and holidays, (d) therapist's contact third parties, (e) disruption of session, (f) time extension and time reduction of session, (g) observation mirror, (h) forced termination of treatment, and (i) touching toys. The analysis of data was limited to: (a) triggers, (b) polarity of themes and images, (c) perceptions of the therapist, (d) models of rectification, and (e) vicissitudes of resistances. This is a limited, multiple case empirical study of two boys (ages 5 and 11) and one girl (age 6) in individual psychotherapy in a public clinic setting. The process of unconscious validation and non-validation by the client was used to determine the correctness of individual hypotheses, which were formed for each session on the basis of the state of the frame. Conclusive empirical proof of the effects of three types of breaks in the frame on the process of child psychotherapy is presented: contact with third parties, observation mirror, and changing the time for sessions adversely influence the process of child psychotherapy. These three findings were made possible because the available data included the breaking as well as securing of the frame which permitted the execution of complete Langsian analysis. Each of the three instances represents a piece of conclusive evidence of the predictive value of Langs' theory regarding children and therefore conclusive evidence of the three aspects of the basic thesis of this study. The analysis of data revealed that the individual Langsian hypotheses were correct in all instances. The analysis also revealed that none of the data would satisfy a rival hypothesis which would propose an outcome opposite to Langsian hypotheses. A limitation of the study is the fact that the majority of available data contained material that allowed only partial Langsian analysis of the impact of the frame on the child. Further studies of secure frame psychotherapy are needed to complete the set of ground rules and boundaries of child psychotherapy by empirical means.

description: We report observations of the recurrent nova RS Oph using long-baseline near-IR interferometry. We are able to resolve emission from the nova for several weeks after the February 2006 outburst. The near-IR source initially expands to a size of approximately 5 milli-arcseconds. However, beginning around day 10 the IR source appears to begin to shrink, reaching approximately 2 milli-arcseconds by day 100. We combine our measured angular diameters with previously available interferometric and photometric data to derive an emission measure for the source, and hence are able to determine the mass-loss rate of the nova in the days following the outburst.

description: We consider a budget constrained rail network electrification problem with associated changes in costs of energy usage (via path gradient and curvature), operations, and long-term maintenance. In particular, we consider that freight flows on such a network form a user equilibrium. Interactions between electric and diesel trains on the same corridor are represented with nonseparable link performance functions, which nevertheless have a symmetric Jacobian. This bi-level formulation is solved for the North American railroad network using a genetic algorithm (GA), incorporating domain-specific insights to reduce the number of solutions which must be considered. We analyze solution characteristics and decision-making implications. Results show that broad connectivity would be beneficial for most impact. Increasing demand shifts electrified corridors towards the more populous east and gulf coasts, while increased operational costs results in electrification of routes through mountainous terrains.
FRW barotropic zero modes: Dynamical systems observability

description: The dynamical systems observability properties of barotropic bosonic and fermionic FRW cosmological oscillators are investigated. Nonlinear techniques for dynamical analysis have been recently developed in many engineering areas but their application has not been extended beyond their standard field. This paper is a small contribution to an extension of this type of dynamical systems analysis to FRW barotropic cosmologies. We find that determining the Hubble parameter of barotropic FRW universes does not allow the observability, i.e., the determination of neither the barotropic FRW zero mode nor of its derivative as dynamical cosmological states. Only knowing the latter ones correspond to a rigorous dynamical observability in barotropic cosmology

description: Recently, it was shown that quantum entanglement is an indispensable part of the duality behavior of light. Here, we report a surprisingly intimate connection between the stereographic projection and the duality--entanglement nature of a single photon. We show that, the duality--entanglement relation [Optica \textbf{5}, 942 (2018)], naturally emerges from the stereographic projection geometry. We demonstrate that this geometry is complementarity sensitive; in the sense that, it is sensitive to the particle nature, wave nature, and entanglement nature of a single photon.

Leptonic widths of heavy quarkonia: QCD/NRQCD matching for the electromagnetic current at O(α_s v^2)

description: We construct the S-wave part of the electromagnetic vector annihilation current to $O(α_s v^2)$, where $v$ is the non-relativistic quark velocity, for heavy quarks whose dynamics are described by the NRQCD action on the lattice. The NRQCD vector current for $Q\bar{Q}$ annihilation is expressed as a linear combination of lattice operators with quantum numbers L=0, $J^P=1^-$, and the coefficients are determined by matching to the corresponding continuum current in QCD to$O(v^2)$ at one-loop. The annihilation channel gives a complex amplitude with Coulomb-exchange and infrared singularities, making a careful choice for the contours of integration and infrared subtraction functions in the numerical integration necessary. An automated vertex generation program written in Python is employed, allowing us to use a realistic NRQCD action and an improved gluon lattice action; a change in the definition of either action is easily accommodated in this procedure. The final result is applicable to simulations of electromagnetic decays of heavy quarkonia, notably the $Υ$ meson.

description: We demonstrate the low temperature suppression of the platinum (Pt) spin Nernst angle in bilayers consisting of the antiferromagnetic insulator hematite ($α$-Fe$_2$O$_3$) and Pt upon measuring the transverse spin Nernst magnetothermopower (TSNM). We show that the observed signal stems from the interplay between the interfacial spin accumulation in Pt originating from the spin Nernst effect and the orientation of the Néel vector of $α$-Fe$_2$O$_3$, rather than its net magnetization. Since the latter is negligible in an antiferromagnet, our device is superior to ferromagnetic structures, allowing to unambiguously distinguish the TSNM from thermally excited magnon transport (TMT), which usually dominates in ferri/ferromagnets due to their non-zero magnetization. Evaluating the temperature dependence of the effect, we observe a vanishing TSNM below ~100 K. We compare these results with theoretical calculations of the temperature dependent spin Nernst conductivity and find excellent agreement. This provides evidence for a vanishing spin Nernst angle of Pt at low temperatures and the dominance of extrinsic contributions to the spin Nernst effect.

description: A generalized two-dimensional periodic Dirac operator is considered, with $L^{\infty}$-matrix-valued coefficients of the first order derivatives and with complex matrix-valued potential. It is proved that if the matrix-valued potential has zero bound relative to the free Dirac operator, then the spectrum of the operator in question contains no eigenvalues.

description: We study the homogenous quenching processes in a holographic s+p model with reentrant phase transitions. We first realize the reentrant phase transition in the holographic model in probe limit and draw the phase diagram. Next, we compare the time evolution of the two condensates in two groups of numerical quenching experiments across the reentrant region, with different quenching speed as well as different width of the reentrant region, respectively. We also study the dynamical competition between the two orders in quenching processes from the normal phase to the superconductor phase.
