description: The purpose of this study was to examine teachers’ integration of technology from multiple perspectives to gain a rich and contextualized understanding of how they genuinely use technology in the classroom. Four research questions were addressed in this study; (a) What influence does technology infrastructure have on teachers using technology? (b) What do teachers believe and think about technology? (c) What is the technological culture that teachers’ experience? (d) What is the influence of policies on teachers’ use of technology? Wilber’s Integral methodological pluralism was used as a framework to orient the study, to organize the research questions and to provide the conceptual framework for the research methodology. Teachers experience a lack of access to technology which proved to be a barrier to most. However, teachers with mature understanding of technology enabled student knowledge creation, successfully overcame these barriers. Teachers must navigate the changing technology connected classroom culture for students to experience academic success. Teachers struggle with policies that make the technology program of studies vague and without specific outcomes. However, a ministerial focus on technology to support the communication and creation of knowledge by students rather than on supporting teaching, encourages the development of mature technology integration.

description: In this combined methods study, semi-structured qualitative interview data and quantitative social network survey data were used to describe the characteristics, functions, and dynamics of new mothers’ social networks in the Canadian context. The social networks of the mothers who participated were largely composed of a core network of close family and friends who provided a range of social support. First time mothers’ networks also included network members who provided support specific to the context of new motherhood, such as daytime companionship during the regular work week, which they found through existing ties when possible. When not, new mothers often sought this companionship through acquaintances or new friends, particularly other new mothers. Comparison of structured social network data with semi-structured interview data led to recommendations for better eliciting and describing these context specific ties in new mothers’ networks, including the use of a multi-pronged, context aware approach.

description: In the framework of density-functional theory, several popular density functionals for exchange and correlation have been constructed to satisfy a local form of the Lieb-Oxford bound. In its original global expression, the bound represents a rigorous lower limit for the indirect Coulomb interaction energy. Here we employ exact-exchange calculations for the G2 test set to show that the local form of the bound is violated in an extensive range of both the dimensionless gradient and the average electron density. Hence, the results demonstrate the severity in the usage of the local form of the bound in functional development. On the other hand, our results suggest alternative ways to construct accurate density functionals for the exchange energy.

description: The $U(1)$ Dirac spin liquid might realize an exotic phase of matter whose low-energy properties are described by quantum electrodynamics in $2+1$ dimensions, where gapless modes exists but spinons and gauge fields are strongly coupled. Its existence has been proposed in frustrated Heisenberg models in presence of frustrating super-exchange interactions, by the (Abrikosov) fermionic representation of the spin operators [X.-G. Wen, \href{https://doi.org/10.1103/PhysRevB.65.165113}{Phys. Rev. B {\bf 65}, 165113 (2002)}], supplemented by the Gutzwiller projection. Here, we construct charge-$Q$ monopole excitations in the Heisenberg model on the triangular lattice with nearest- ($J_1$) and next-neighbor ($J_2$) couplings. In the highly frustrated regime, singlet and triplet monopoles with $Q=1$ become gapless in the thermodynamic limit; in addition, the energies for generic $Q$ agree with field-theoretical predictions, obtained for a large number of gapless fermion modes. Finally, we consider localized gauge excitations, in which magnetic $π$-fluxes are concentrated in the triangular plaquettes (in analogy with $\mathbb{Z}_2$ visons), showing that these kind of states do not play a relevant role at low energies. All our findings lend support to a stable $U(1)$ Dirac spin liquid in the $J_1-J_2$ Heisenberg model on the triangular lattice.

description: Technological innovation is at the heart of many discussions of understanding military practice, and it is increasingly important to understanding the relationship between states, militaries, and civilian actors such as a corporations and citizens increasingly shaped by militarization. One group of technologies affected and whose development has been conditioned by these discussions is simulation software. Based upon four months of participant observation research at a defence contractor and software development company in Calgary, Alberta, this study explores how contingencies of professional practice in the software industry, authority, corporate hierarchy and reporting practices, gender, and the nature of simulation contribute to developing products for military use. This study suggests that these contingencies not only reproduce and reinforce certain gendered, authoritative, and professional stereotypes during production, but that understanding these stereotypes and their linguistic, aesthetic, and structured facets contributes to understanding the relationship between militarization and the production of technology.

The method also reproduces the projectors $|ψ^R_n>

description: Rockfall processes are important contributors to hillslope erosion in mountainous regions. Assessment of rockfall activity processes over regional scales has not been widely undertaken, and further assessment about controls of rockfall-talus processes is required. The present study investigates rockfall-talus processes over extended spatiotemporal scales in Kananaskis, Canadian Rockies utilizing aerial photographs, digital elevation models, geologic and paleoclimatic data. An inventory of talus deposits in fifth-order drainage basins was collected for Kananaskis, with rockfall erosion rates of 2.9 mm yr-1. Results show a strong association of talus with faults and cirques. Although frost cracking is likely an important process leading to rockfall erosion, reconstructed temperature data suggests frost cracking alone is not the major determinant of locations of rockfall activity and talus deposition. Findings of this study provide important information on the contribution and controls of rockfall activity that can be utilized to better understand landscape evolution in mountainous regions.

description: In ultra-relativistic heavy ion collisions, the matter formed shortly after the collision is a dense, out of equilibrium, system of gluons characterized by a semi-hard momentum scale $Q_{\rm s}$. Simple power counting arguments indicate that this system is over-occupied: the gluon occupation number is parametrically large when compared to a system in thermal equilibrium with the same energy density. On short time scales, soft elastic scatterings tend to drive the system towards the formation of a Bose--Einstein condensate that contains a large fraction of the gluons while contributing little to the energy density. The lifetime and existence of this condensate depends on whether inelastic processes, that occur on the same time scale as the elastic ones, preferably increase or decrease the number of gluons. During this overpopulated stage, and all the way to thermalization, the system behaves as a strongly interacting fluid, even though the elementary coupling constant is small. We argue that while complete isotropization may never be reached, the system may yet evolve for a long time with a fixed anisotropy between average longitudinal and transverse momenta.

description: The rapid decline in international oil prices forced oil and gas industries to reduce costs, improve productivity and layoff thousands of employees. Specifically, the majority of resources located in Alberta require thermal recovery methods due to their heavy characteristics. Innovation is required to displace current extraction methods that are becoming economically challenging. The present work studies the dense hot fluid injection (DHFI) process, which targets the in situ catalytic upgrading and extraction of Athabasca bitumen. A bench-scale set up was designed and built. The experimental results were integrated using process simulation and life cycle assessments (LCA) techniques to estimate GHG emissions of the new technology. Results confirmed quality improvement of the feedstock while maintaining a stable product. The experimental setup proved differences in the heat distribution profiles between SAGD and the DHFI. LCA demonstrated that the DHFI could produce less GHG emissions than SAGD under a set of assumed scenarios.

description: Refugee entrepreneurs can make a significant contribution to sustainable growth and development in host countries. However, comprehensive comparative studies of refugee entrepreneurial motivations are scarce, particularly in the absence of a theoretical framework on entrepreneurship motivation that is suitable for such contexts. This is a research topic that is increasingly of interest to scholars and policymakers working with refugee workforce integration, particularly in light of forecasted increases in global forced displacement over the next years. This paper tests and extends newly constructed entrepreneurship motivation measures, comparing person-related factors and the perceptions of environmental-related factors for Syrian refugee entrepreneurs in Sweden and Germany. The results indicate that their motivations differ between the two countries with respect to market conditions, the educational environment, dissatisfaction, and know-how. However, refugee entrepreneurs in both countries have similar levels of entrepreneurial ambition and attitude and are motivated by similar perceptions of social environments and cultural norms. This paper identifies how entrepreneurship motivation differences could be considered by governments to better shape and inform host countries’ programs and policies to improve refugee entrepreneurship and subsequent integration.
Absolute dimensions of solar-type eclipsing binaries. EF Aquarii: a G0 test for stellar evolution models

description: Recent studies have shown that stellar chromospheric activity, and its effect on convective energy transport in the envelope, is most likely the cause of significant radius and temperature discrepancies between theoretical evolution models and observations. We aim to determine absolute dimensions and abundances for the solar-type detached eclipsing binary EF Aqr, and to perform a detailed comparison with results from recent stellar evolutionary models. uvby-beta standard photometry was obtained with the Stromgren Automatic Telescope. The broadening function formalism was applied on spectra observed with HERMES at the Mercator telescope in La Palma, to obtain radial velocity curves. Masses and radii with a precision of 0.6% and 1.0% respectively have been established for both components of EF Aqr. The active 0.956 M_sol secondary shows star spots and strong Ca II H and K emission lines. The 1.224 M_sol primary shows signs of activity as well, but at a lower level. An [Fe/H] abundance of 0.00+-0.10 is derived with similar abundances for Si, Ca, Sc, Ti, V, Cr, Co, and Ni. Solar calibrated evolutionary models such as Yonsei-Yale, Victoria-Regina and BaSTI isochrones and evolutionary tracks are unable to reproduce EF Aqr, especially for the secondary, which is 9% larger and 400 K cooler than predicted. Models adopting significantly lower mixing length parameters l/H_p remove these discrepancies, as seen in other solar type binaries. For the observed metallicity, Granada models with a mixing length of l/H_p=1.30 (primary) and 1.05 (secondary) reproduce both components at a common age of 1.5+-0.6 Gyr. Observations of EF Aqr suggests that magnetic activity, and its effect on envelope convection, is likely to be the cause of discrepancies in both radius and temperature, which can be removed by adjusting the mixing length parameter of the models downwards.

description: In machining, a phenomenon known as chatter, which is a self-excited excessive vibration, is considered one of the most limiting factors for productivity. Particularly in boring process, the long cantilevered structure of boring bar makes it the most flexible part of machine tool system. As a result, there is a high possibility for chatter to occur compared with other machine tool components. In this research, two methods were investigated to attenuate chatter and increase stability in boring operations by manipulating the boring bar structure dynamics. First, the effect of altering the boring bar’s natural frequency on chatter is investigated through varying the boring bar’s overall mass. Second, a tuned liquid column damper (TLCD) is developed to improve the dynamic stiffness for boring bars application for improving the overall stability. Several models and experiments are carried out for evaluating the performance of the proposed methods.

description: Since their derivation in 1998, human embryonic stem cells (ESCs) have been of great interest within the realm of regenerative medicine. Their ability to differentiate into any cell type of the adult body makes them an incredibly powerful and exciting tool with respect to potential treatments for long-term degenerative diseases. Stirred suspension bioreactors have been the focus of many publications anticipating the need for high numbers of clinically-relevant cells for therapeutic applications. As evidenced by the wide range of published protocols and resulting culture output, the field is currently lacking in well designed, systematic investigations into the true effect of varying culture parameters not only in suspension conditions but also within standard static cultures. This research was carried out to address gaps that currently exist within current ESC culture protocols first by establishing a base line for culture kinetics, during which the issue of morphological evaluation was identified. With the goal of eliminating the subjective nature of morphological evaluation, fractal geometry was utilized to assign a quantitative value (fractal dimension) to ESC cultures. Results indicate a significant difference between fractal dimensions determined for pluripotent cells versus differentiating cells suggesting that fractal geometry may be used to monitor culture health. A more standardized methodology for static culture monitoring will allow for more homogeneous population of ESCs as inoculum for large scale expansion efforts. Finally, a 3^2 factorial experimental design was developed and executed for stirred suspension culture of ESCs illustrating the potential for interaction effects and suggesting for the first time that the use of the conventional stepwise optimisation approach to stirred suspension culture is not appropriate.

description: The central star and its energetic radiation fields play a vital role in setting the vertical and radial chemical structure of planet-forming disks. We present observations that, for the first time, clearly reveal the UV-irradiated surface of a protoplanetary disk. Specifically, we spatially resolve the atomic-to-molecular (C I-to-CO) transition in the IM Lup disk with ALMA archival observations of [C I] 3P1-3P0. We derive a C I emitting height of z/r ≳ 0.5 with emission detected out to a radius of ≈600 au. Compared to other systems with C I heights inferred from unresolved observations or models, the C I layer in the IM Lup disk is at scale heights almost double that of other disks, confirming its highly flared nature. C I arises from a narrow, optically-thin layer that is substantially more elevated than that of 12CO (z/r ≈ 0.3-0.4), which allows us to directly constrain the physical gas conditions across the C I-to-CO transition zone. We also compute a radially-resolved C I column density profile and find a disk-averaged C I column density of 2×10^16 cm-2, which is ≈3-20× lower than that of other disks with spatially-resolved C I detections. We do not find evidence for vertical substructures or spatially-localized deviations in C I due, e.g., to either an embedded giant planet or a photoevaporative wind that have been proposed in the IM Lup disk, but emphasize that deeper observations are required for robust constraints.

description: We sought to identify the barriers to cervical cancer screening among South Asian Muslim immigrant women in Calgary. Qualitative, semi-structured in-depth interviews, by snowball sampling, were conducted with South Asian Muslim immigrant women of Calgary who were unscreened or infrequently screened for cervical cancer. Eighteen women were interviewed and the majority (66%) never had a Pap test. Major findings include: misunderstanding about Pap test reminders, strong preference for a female physician who also speaks their language, negative experiences with healthcare providers including painful Pap test experience. Major barriers involved: lack of knowledge about cervical cancer, fatalist beliefs, transportation, language and unavailability of female physicians. Separate centers for Pap testing, awareness and encouragement by healthcare providers to get tested were strategies participants suggested. Different healthcare strategies are needed at the system and provider level to improve healthcare experience of these women and to promote cervical cancer screening.

description: The partition function on the three-sphere of N=3 Chern-Simons-matter theories can be formulated in terms of an ideal Fermi gas. In this paper we show that, in theories with N=2 supersymmetry, the partition function corresponds to a gas of interacting fermions in one dimension. The large N limit is the thermodynamic limit of the gas and it can be analyzed with the Hartree and Thomas-Fermi approximations, which lead to the known large N solutions of these models. We use this interacting fermion picture to analyze in detail N=2 theories with one single node. In the case of theories with no long-range forces we incorporate exchange effects and argue that the partition function is given by an Airy function, as in N=3 theories. For the theory with g adjoint superfields and long-range forces, the Thomas-Fermi approximation leads to an integral equation which determines the large N, strongly coupled R-charge.

description: We present a dedicated analysis of the influence of excited states on the calculation of nucleon matrix elements. This calculation is performed at a fixed value of the lattice spacing, volume and pion mass that are typical of contemporary lattice computations. We focus on the nucleon axial charge, g_A, for which we use about 7,500 measurements, and on the average momentum of the unpolarized isovector parton distribution, _{u-d}, for which we use about 23,000 measurements. All computations are done employing N_f=2+1+1 maximally-twisted-mass Wilson fermions and using non-perturbatively calculated renormalization factors. Excited state effects are shown to be negligible for g_A whereas they lead to an O(10%) downward shift for _{u-d}.

description: We report on experimental studies of magnetoresistance oscillations that originate from the resonant interaction of two-dimensional electrons with thermal transverse-acoustic phonons in very high-mobility GaAs/AlGaAs quantum wells. We find that the oscillation maxima consistently occur when a frequency of a phonon with twice the Fermi momentum exceeds an integer multiple of the cyclotron frequency. This observation is in contrast to to all previous experiments associating resistance maxima with magnetophonon resonance and its harmonics. Our experimentally obtained resonant condition is in excellent quantitative agreement with recent theoretical proposals.

description: Kilonovae, possible electromagnetic counterparts to neutron star mergers, provide important information about high-energy transient phenomena and, in principle, also allow us to obtain information about the source properties responsible for powering the kilonova. Unfortunately, numerous uncertainties exist in kilonova modeling that, at the current stage, hinder accurate predictions. Hence, one has to account for possible systematic modeling uncertainties when interpreting the observed transients. In this work, we provide a data-driven approach to account for time-dependent and filter-dependent uncertainties in kilonova models. Through a suite of tests, we find that the most reliable recovery of the source parameters and description of the observational data can be obtained through a combination of kilonova models with time- and filter-dependent systematic uncertainties. We apply our new method to analyze AT2017gfo. While recovering a total ejecta mass consistent with previous studies, our approach gives insights into the temporal and spectral evolution of the systematic uncertainties of this kilonova. We consistently find a systematic error below $1$ mag between $1$ to $5$ days after the merger. Our work addresses the need for early follow-up of kilonovae at earlier times, and improved modeling of the kilonova at later times, to reduce the uncertainties outside of this time window.

Time judgments in dual-task conditions

Publisher: name: University of British Columbia
Year: 2010

description: Every day we complete a number of tasks which require us to accurately time events, from estimating how long it will take us to drive to work in the morning to steeping our afternoon tea for the correct duration. Although timing is very important in our everyday lives, we know relatively little about how we process time information. Many models have been proposed to account for human timing, with the most prominent are the attentional gate model (AGM) and the multiple resources model. The AGM and the multiple resources model make many similar predictions about human timing, and it is often difficult to discriminate between the two. Toward this goal, the present research focused on a situation in which the two models make opposing predictions, that is, conditions which require participants two carry out two tasks concurrently with both of them requiring time-related processing.. Three experiments are reported, in which subjects were asked to estimate various shorter or longer intervals while concurrently carrying out a task that either required processing of time-related information or non-time based information. Results of all three studies seem more supportive of the multiple resources model of timing, rather than the AGM.
Seismic Forward Modeling of Fractures and Fractured Media Inversion

description: The goal of this thesis is to develop a methodology for enhancing fracture detection and correctly delineating reservoirs with fractures. The thesis deeply explores the mechanical formation of fractures and fractured media, presents an enhanced fracture detection technique that uses a new finite-difference scheme to accurately model fractures and analyze the fracture response in seismic traveltime and amplitude, and develops a method for accurate reservoir delineation by deriving new AVO fracture equations to correctly estimate the properties of the fractured medium, the host medium and fractured medium with impedance contrast. With the long wavelength assumption, a linear slip interface is equivalent to a fracture interface that satisfies the nonwelded contact boundary conditions. Therefore, the fractured medium can be regarded as a combination of a fracture, or a set of fractures, and a host medium: a horizontally fractured medium is effectively composed of a horizontal fracture embedded into a homogeneous isotropic host medium; and a vertically fractured medium is effectively formed by inserting a vertical fracture into a homogeneous isotropic host medium; an orthogonally fractured medium is effectively assembled from a vertical fracture and a homogeneous VTI host medium, or a horizontal fracture and a homogeneous HTI host medium, or two orthorhombic fractures and a homogeneous isotropic host medium. New finite-difference schemes for horizontal, vertical and orthorhombic fractures are implemented to generate seismograms that precisely illustrate the fracture representations in seismic data. The results indicate that the fractures are detectable, even though the fractured medium does not have impedance contrasts, and that the fractured medium can be characterized as a transversely isotropic medium. Through an analysis of how fractures are represented in seismic data can help in fracture detection in geoscience. New exact equations for the reflection and transmission coefficients of a fractured medium with impedance contrast are derived that take into account the azimuthal parameter and the nonwelded contact boundary conditions. New approximate AVO equations that include fracture parameters are derived. Therefore, the fracture, the host medium and the fractured medium with impedance contrast properties can be estimated from seismic data to correctly delineate the reservoir characterization.

description: Introduction:
 There is growing concern on inappropriate disposal of unused medications and its consequences to environment and public health. Misconception among public on disposal of unused medications to environment due to convenience and lack of appropriate education is a matter of discussion in our study. This study was designed to determine Knowledge, Attitude and Practice (KAP) towards return and disposal of unused medications. Methodology:
 A cross sectional study was performed using validated questionnaire with 500 randomly selected individuals among public in Sibu including those participating in pharmacy-based events as well as patients attending Out-patient Clinics in Sibu Hospital. They were interviewed on KAP towards return and disposal of unused medications. Results:
 The mean knowledge score obtained from our study was 5.426. For knowledge part, 81.6% of participants knew that returning unused medications to pharmacy is a correct way. However, 70.2% of participants wrongly answered for correct statement "Incineration as a way of drug disposal", probably because they had mistaken term of "incineration" as open burning. There is a statistically significant relationship between education level of subjects and knowledge with P=0.002. Nevertheless, no correlation among other socio-demographic data and knowledge of participants. Meanwhile, for attitude and practice, majority participants showed positive attitude and practice on return and disposal of unused medications. Conclusion:
 As there is a statistically significant relationship between education level and knowledge, therefore pharmacist plays a role in creating public awareness on safe medication disposal by highlighting importance of drug return and safe medication disposal methods.

description: The purpose of this qualitative case study was to examine community college teachers’ perceptions of racial diversity through their day-to-day interactions with students, other faculty, and the school administration. As the researcher and a part-time faculty member of a community college, I conducted interviews with seven participants from the college where I am employed, and also asked participants to engage in six weeks of journaling. Additional research included a document review of more than 550 course outlines, researching them for inclusion of racial diversity components, as well as keeping my own personal journal. My research questions focused on defining and understanding racial diversity, challenges within the classroom, addressing issues of racial diversity in a learning environment and the development and delivery of diversity-focused curriculum. Based on my data analysis, four key findings emerged: racial diversity in the classroom is difficult to define and embrace; addressing racial diversity issues is challenging for educators; faculty need administrative support to embrace diversity; and the development and delivery of a more diversity-focused curriculum is necessary. I concluded that educators are challenged by racial diversity in the classroom environment, resources to understand and embrace racial diversity are not always present or accessible, and more action must be taken to support faculty in the development and delivery of diversity-focused curriculum.

description: We show how to exchange (braid) Majorana fermions in a network of superconducting nanowires by control over Coulomb interactions rather than tunneling. Even though Majorana fermions are charge-neutral quasiparticles (equal to their own antiparticle), they have an effective long-range interaction through the even-odd electron number dependence of the superconducting ground state. The flux through a split Josephson junction controls this interaction via the ratio of Josephson and charging energies, with exponential sensitivity. By switching the interaction on and off in neighboring segments of a Josephson junction array, the non-Abelian braiding statistics can be realized without the need to control tunnel couplings by gate electrodes. This is a solution to the problem how to operate on topological qubits when gate voltages are screened by the superconductor.

description: Goal-oriented chatbots are essential for automating user tasks, such as booking flights or making restaurant reservations. A key component of these systems is Dialogue State Tracking (DST), which interprets user intent and maintains the dialogue state. However, existing DST methods often rely on fixed ontologies and manually compiled slot values, limiting their adaptability to open-domain dialogues. We propose a novel approach that leverages instruction tuning and advanced prompt strategies to enhance DST performance, without relying on any predefined ontologies. Our method enables Large Language Model (LLM) to infer dialogue states through carefully designed prompts and includes an anti-hallucination mechanism to ensure accurate tracking in diverse conversation contexts. Additionally, we employ a Variational Graph Auto-Encoder (VGAE) to model and predict subsequent user intent. Our approach achieved state-of-the-art with a JGA of 42.57% outperforming existing ontology-less DST models, and performed well in open-domain real-world conversations. This work presents a significant advancement in creating more adaptive and accurate goal-oriented chatbots.

description: The goal of this document is to present the technical specifications and design of BIGG Architecture building blocks. As one of the main deliverables of the WP2, it presents the overall description of the elementary BIGG components and it describes the architectural possibilities to use and organize these components. These components are software units with well-defined purposes such as retrieving data, transforming data, analyzing data or coordinating data flows.
One of the key findings of BIGG is that, to fulfil all requirements from pilots, the BIGG architecture should not be exclusively a cloud-based system. The proposed solution must be modular and flexible in terms of BIGG components deployment choices. Actually, BIGG components must be deployable locally on partners infrastructures where BIGG components can be close to the place where the data that will be exploited resides. Therefore, the BIGG technical specifications specify a "pick and choose" system with components that end-users may take and deploy individually. Architectural guidelines describe state-of-the-art ways to organize these components' interactions.
Spinmotive Force due to Intrinsic Energy of Ferromagnetic Nanowires

description: We study, both analytically and numerically, a spinmotive force arising from inherent magnetic energy of a domain wall in a wedged ferromagnetic nanowire. In a spatially-nonuniform nanowire, domain walls are subjected to an effective magnetic field, resulting in spontaneous motion of the walls. The spinmotive force mechanism converts the ferromagnetic exchange and demagnetizing energy of the nanowire into the electrical energy of the conduction electrons through the domain wall motion. The calculations show that this spinmotive force can be several microvolts, which is easily detectable by experiments.

description: We present the results of a deep (J ~ 21 mag at 5 sigma) infrared photometric survey of a 0.95 square degree area in the central region of the Upper Sco association. The photometric observations consist of a deep (Y+J)-band images obtained with the WFCAM camera on the UKIRT InfraRed Telescope (UKIRT) with partly coverage in Z complemented by methane ON and OFF conducted with WIRCam on the Canada France Hawaii Telescope. We have selected five potential T-type objects belonging to the Upper Sco association on the basis of their blue methane colours and their J-CH4off colours. We have also identified a sample of 7-8 Upper Sco member candidates bridging the gap between known cluster M-types and our new T-type candidates. These candidates were selected based on their positions in various colour-magnitude diagrams and they follow the sequence of known Upper Sco members identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS). We present additional membership constraints using proper motion estimates from the multiple epochs available to us. We also present optical and near-infrared spectra obtained with the X--Shooter spectrograph on the Very Large Telescope for five L-type candidates covering the 0.6 to 2.5 micron wavelength range, none of them being confirmed as a young brown dwarf. We discuss the lack of detection of new candidate members as well as the possible turn down in the USco mass function as we are approaching the fragmentation limit.

description: The generation of intrinsic rotation by turbulence and neoclassical effects in tokamaks is considered. To obtain the complex dependences observed in experiments, it is necessary to have a model of the radial flux of momentum that redistributes the momentum within the tokamak in the absence of a preexisting velocity. When the lowest order gyrokinetic formulation is used, a symmetry of the model precludes this possibility, making small effects in the gyroradius over scale length expansion necessary. These effects that are usually small become important for momentum transport because the symmetry of the lowest order gyrokinetic formulation leads to the cancellation of the lowest order momentum flux. The accuracy to which the gyrokinetic equation needs to be obtained to retain all the physically relevant effects is discussed.
