Collective modes, stability and superfluid transition of a quasi-two-dimensional dipolar Fermi gas

description: We examine collective modes, stability, and BCS pairing in a quasi-two-dimensional gas of dipolar fermions aligned by an external field. By using the (conserving) Hartree-Fock approximation, which treats direct and exchange interactions on an equal footing, we obtain the spectrum of single-particle excitations and long wavelength collective modes (zero sound) in the normal phase. It appears that exchange interactions result in strong damping of zero sound when the tilting angle between the dipoles and the normal to the plane of confinement is below some critical value. In particular, zero sound cannot propagate if the dipoles are perpendicular to the plane of confinement. At intermediate coupling we find unstable modes that can lead either to collapse of the system or the formation of a density wave. The BCS transition to a superfluid phase, on the other hand, occurs at arbitrarily weak strengths of the dipole-dipole interaction, provided the tilting angle exceeds a critical value. We determine the critical temperature of the transition taking into account many-body effects as well as virtual transitions to higher excited states in the confining potential, and discuss prospects of experimental observations.
Regional-scale distributed modelling of glacier meteorology and melt, southern Coast Mountains, Canada
Creators: name: Shea, Joseph Michael
Publisher: name: University of British Columbia
Year: 2010

description: Spatially distributed regional scale models of glacier melt are required to assess the potential impacts of climate change on glacier response and proglacial streamflow. The objective of this study was to address the challenges associated with regional scale modelling of glacier melt, specifically by (1) developing methods for estimating regional fields of the meteorological variables required to run melt models, and (2) testing models with a range of complexity against observed snow and ice melt at four glaciers in the southern Coast Mountains, ranging in size from a small cirque glacier to a large valley glacier. Near-surface air temperature and humidity measured over four glaciers in the southern Coast Mountains of British Columbia were compared to ambient values estimated from a regional network of off-glacier weather stations. Systematic differences between measured and ambient conditions represent the effects of katabatic flow, and were modelled as a function of flow path length calculated from glacier digital elevation models. Near-surface wind speeds were classified as either katabatic or channelled, and were modelled based on Prandtl flow (for katabatic winds) or gradient wind speeds. Models for atmospheric transmissivity, snow and ice albedo, and incoming longwave radiation were tested and developed from observations of incident and reflected shortwave radiation and incoming longwave radiation. Data from a regional climate network were used to run a degree-day model, a radiation-indexed degree-day model, a simple energy balance model (including tuned parameters for turbulent exchange) and two full energy balance models (incorporating stability corrections, with and without corrections for katabatic effects on air temperature and humidity). Modelled melt was compared to mass balance measurements of seasonal snow and ice melt. Models were also compared based on their ability to predict date of snow disappearance, given an initial snowpack water equivalence. The degree-day model outperformed the simple energy balance and radiation-indexed degree-day approaches, while the full energy balance model without katabatic boundary layer corrections yielded the lowest errors.

description: The increasing trend toward multi-device ecologies that provide private and shared digital surfaces introduces a need for effective cross-device object transfer interaction mechanisms. This work-in-progress paper investigates visual feedback techniques for enhancing the usability of the Pick-and-Drop cross-device object transfer technique when used between a shared digital table and private tablets. We propose two visual feedback designs aimed to improve awareness of virtual objects during a Pick-and-Drop transfer. Initial results from a comparative user study are presented and discussed, along with directions for future work.

description: We test the AdS/CFT correspondence by calculating Wilson loops in N = 4 super Yang-Mills theory on R*S^3 in the planar limit. Our method is based on a novel large-N reduction, which reduces the problem to Monte Carlo calculations in the plane-wave matrix model or the BMN matrix model, which is a 1d gauge theory with 16 supercharges. By using the gauge-fixed momentumspace simulation, we obtain results respecting 16 supersymmetries. We report on the Monte Carlo results for the BPS circular Wilson loop, which reproduce the exact result up to strong coupling. As a future prospect, we calculate a track-shapedWilson loop from the gravity side, which shows that a clear test of the AdS/CFT for the non-BPS case is also feasible.

description: Plastic materials have become pervasive in 21st century economies, yet 60% of all plastics ever produced globally have been discarded either in landfills or elsewhere in the environment. This represents not only significant economic and material resource losses, but accumulation of plastics in natural environments can also impact wildlife and ecosystem wellbeing. Efforts to address plastic waste concerns are vast and diverse, involving every stage of the plastic supply chain, including development of alternative materials; innovative design and re-design of products and packaging systems; and improvements in recycling processes and markets. Such advancements will require capital investment, and as such, strategic investors can influence the rate and direction of plastic waste reduction efforts. Experience from industrial ecology and related fields demonstrates that reducing plastic use or plastic waste does not necessarily result in reduction in environmental sustainability indicators such as energy use, greenhouse gas emissions, and water use. Additional guidance is needed to assure that promising plastic waste reduction innovations also meet broader sustainable development goals. This report introduces the Plastic waste Reduction Innovation Sustainability Evaluation Tool (PRISET). The aim is to provide a guide for experts and non-experts to assess the sustainability performance of emerging products, technologies and services that can reduce plastic waste. PRISET builds upon existing frameworks, tools, knowledge bases and experiences of industrial ecology, life cycle assessment, circular economy and ESG reporting.
Investigating attraction and engagement of animation on large interactive walls in public settings

Publisher: name: ACM
Year: 2013

description: Large interactive walls capable of delivering dynamic content to broad audiences are becoming increasingly common in public areas for information dissemination, advertising, and entertainment purposes. A major design challenge for these systems is to entice and engage passersby to interact with the system, and in a manner intended by the designers. To address this issue, we are examining the use of different types of animation at various stages of the interaction as someone approaches and begins interacting with the system. Using usage measures from museum studies, namely, attraction and engagement of an exhibit, we plan to assess the effectiveness of different types of animation in the context of an interactive notice board application in a university campus. We describe our design approach and plans for studying the animation design in a real-world public setting.

description: DNA is subject to large deformations in a wide range of biological processes. Two key examples illustrate how such deformations influence the readout of the genetic information: the sequestering of eukaryotic genes by nucleosomes, and DNA looping in transcriptional regulation in both prokaryotes and eukaryotes. These kinds of regulatory problems are now becoming amenable to systematic quantitative dissection with a powerful dialogue between theory and experiment. Here we use a single-molecule experiment in conjunction with a statistical mechanical model to test quantitative predictions for the behavior of DNA looping at short length scales, and to determine how DNA sequence affects looping at these lengths. We calculate and measure how such looping depends upon four key biological parameters: the strength of the transcription factor binding sites, the concentration of the transcription factor, and the length and sequence of the DNA loop. Our studies lead to the surprising insight that sequences that are thought to be especially favorable for nucleosome formation because of high flexibility lead to no systematically detectable effect of sequence on looping, and begin to provide a picture of the distinctions between the short length scale mechanics of nucleosome formation and looping.

description: This paper presents the design of OrMiS, a tabletop application supporting simulation-based training. OrMiS is notable as one of the few practical tabletop applications supporting collaborative analysis, planning and interaction around digital maps. OrMiS was designed using an iterative process involving field observation and testing with domain experts. Our key design insights were that such a process is required to resolve the tension between simplicity and functionality, that information should be displayed close to the point of the user's touch, and that collaboration around maps cannot be adequately solved with a single form of zooming. OrMiS has been evaluated by domain experts and by officer candidates at a military university.

description: Giant molecular clouds contain supersonic turbulence and simulations of magnetohydrodynamic turbulence show that these supersonic motions decay in roughly a crossing time, which is less than the estimated lifetimes of molecular clouds. Such a situation requires a significant release of energy. We run models of C-type shocks propagating into gas with densities around 10^3 cm^(-3) at velocities of a few km / s, appropriate for the ambient conditions inside of a molecular cloud, to determine which species and transitions dominate the cooling and radiative energy release associated with shock cooling of turbulent molecular clouds. We find that these shocks dissipate their energy primarily through CO rotational transitions and by compressing pre-existing magnetic fields. We present model spectra for these shocks and by combining these models with estimates for the rate of turbulent energy dissipation, we show that shock emission should dominate over emission from unshocked gas for mid to high rotational transitions (J >5) of CO. We also find that the turbulent energy dissipation rate is roughly equivalent to the cosmic-ray heating rate and that the ambipolar diffusion heating rate may be significant, especially in shocked gas.

description: Modifying a digital sketch may require multiple selections before a particular editing tool can be applied. Especially on large interactive surfaces, such interactions can be fatiguing. Accordingly, we propose a method, called Suggero, to facilitate the selection process of digital ink. Suggero identifies groups of perceptually related drawing objects. These "perceptual groups" are used to suggest possible extensions in response to a person's initial selection. Two studies were conducted. First, a background study investigated participant's expectations of such a selection assistance tool. Then, an empirical study compared the effectiveness of Suggero with an existing manual technique. The results revealed that Suggero required fewer pen interactions and less pen movement, suggesting that Suggero minimizes fatigue during digital sketching.

Museums, Communities and Participatory Projects

subject: Applied sociology, program evaluation and social impact assessment

description: Museums have been working with communities of place, practice and interest for
many years to preserve tangible and intangible cultural heritage, develop research
collections and create exhibitions or events. However, in an environment of
increased social and economic accountability, many cultural institutions are now
re-examining the relevance of their activities and are reflecting on the ways in
which they include communities in their programs. This thesis considers the
correlation between participatory theory and principles and the methods
Australian museums use to work with and engage communities. In particular, it
seeks to explore why museum outreach activities, as the dominant medium for
extended community engagement initiatives within museums, have not engaged
more fully with interdisciplinary participatory models, particularly those utilised
by natural resource management (NRM) practitioners.
The thesis explores the difference between the concept of engagement and the
concept of participation and uses a case study approach to reflect on how these are
practiced and understood in the museum milieu. Using outreach projects with a
socio-environmental and NRM focus, I suggest that the integration of
participatory principles and practices has the potential to increase the capacity of
museums and communities to actively contribute to a range of contemporary
social issues and debates. Implicit in this research is an understanding that
consultation gives rise to, but is not equivalent to, participation; that participatory
approaches and relationship building are at once time consuming and yet can be
expedient; and that while not applicable to every museum project, participatory
approaches can inspire interaction, empowerment and creativity in worlds
including and beyond museums.
By exploring these dimensions in relation to interdisciplinary approaches, and
using the examples and case studies explored throughout the thesis, this
dissertation provides museum practitioners with a spectrum/methodology to help
advocate for and/or integrate community engagement strategies into project
development.

description: In this paper, we evaluate the performance and experience differences between direct touch and mouse input on horizontal and vertical surfaces using a simple application and several validated scales. We find that, not only are both speed and accuracy improved when using the multi-touch display over a mouse, but that participants were happier and more engaged. They also felt more competent, in control, related to other people, and immersed. Surprisingly, these results cannot be explained by the intuitiveness of the controller, and the benefits of touch did not come at the expense of perceived workload. Our work shows the added value of considering experience in addition to traditional measures of performance, and demonstrates an effective and efficient method for gathering experience during inter-action with surface applications. We conclude by discussing how an understanding of this experience can help in designing touch applications.

Then we relate it to the descent relative to a suitable cyclic isogeny. This allows us to connect the resulting Selmer group with the logarithmic class group of the base. These constructions are explicit and suitable for computer experimentation. From a conceptual point of view, the questions that arise here are analogues of "visibility" questions in the sense of Cremona and Mazur.

description: The latest advancements in mobile device technology are putting ever-higher demands for throughput of wireless networks. This is threatening to outpace the ability of service providers to deploy the necessary infrastructure. Fifth-Generation Mobile Network (5G) technology is experiencing rapid adoption as part of the effort to meet demand, and along with it researchers are continuously seeking new metrics and models for use in predicting the limits of current and future network infrastructure. To succeed, it is key that they have access to methods for simple, effective analysis of the wireless propagation channel in any given location. The typical laboratory test environment lacks the unpredictability and uniqueness of real-world conditions. Additionally, it utilizes equipment whose specifications are often far removed from devices that are actually intended to operate on the mobile network, such as smartphones themselves. This work focuses on the nature of contemporary path loss models and their ability to accurately predict signal levels, seeking to validate their use against observed path loss behavior in outdoor line-of-sight (LOS) scenarios, where the number of active devices can vary significantly over short periods of time. These conditions are typical of public spaces such as parks and city streets where a large number of users may all simultaneously be accessing high-throughput services. To test their validity, statistics are provided for sets of data collected on foot in public spaces using a novel software utility developed expressly for this purpose. The models we use for comparing against our measured results include both experiential models that are built on other data sets, along with stastically-based, large-scale path loss models. These are compared as a function of distance from the base station (BS), and any unique characteristics of the local network are considered. Finally, a combination of environmental imagery, coverage maps with signal strength overlays, and the aforementioned model comparison are used to estimate the signal source and predict performance in nearby areas.

description: Rekimoto's Pick-and-Drop (P&D) transfer technique is commonly used to support multi-surface object transfer (e.g., between a shared tabletop and tablet) due to its easily understood metaphor of emulating object movement in the physical world. Current multi-surface implementations of P&D provide little to no feedback during transfer, causing confusion for the person performing the action as well as others in the environment. To address this issue, we investigated the use of virtual embodiments to improve awareness of transferred objects, in the context of a real-world group task that relied heavily on cross-device transfer. An iterative design process led to the design of Surface Ghosts virtual embodiments, which take the form of semi-transparent 'ghosts' of the transferred objects displayed under the "owner's" hand on the tabletop during transfer. A user study that compared two Surface Ghosts designs-varied by how explicitly the "owner" was indicated-showed that both designs improved awareness of transferred objects when compared to a no-feedback control condition, especially for tabletop-to-tablet transfers.

description: The minimal 3-3-1 model is perturbative until energies around 4-5TeV, posing a challenge to generate neutrino masses at eV scale, mainly if one aims to take advantage of the seesaw mechanism. As a means to circumvent this problem we propose a modification of the model such that it accommodates the type I and type II seesaw mechanisms altogether. We show that the conjunction of both mechanisms yield a neutrino mass expression suppressed by a high power of the cutoff scale, $M^5$, in its denominator. With such a suppression term we naturally obtain neutrino masses at eV scale when $M$ is around few TeV. We also investigate the size of lepton flavor violation through the process $μ\rightarrow eγ$.

Supporting Situation Awareness in Collaborative Tabletop Systems with Automation

description: Human operators collaborating to complete complex tasks, such as a team of emergency response operators, need to maintain a high level of situation awareness to appropriate-ly and quickly respond to critical changes. Even though automation can help manage complex tasks and rapidly update information, it may create confusion that negatively impacts operators' situation awareness, and result in sub-optimal decisions. To improve situation awareness in co-located environments on digital tabletop computers, we developed an interactive event timeline that enables exploration of historical system events, using a collaborative digital board game as a case study. We conducted a user study to examine two factors, placement of timelines for multiple users and location of awareness feedback, to understand their impact on situation awareness. The study revealed that interaction with the timeline was correlated with improved situation awareness, and that displaying feedback both on the game board and timeline was the most preferred.

description: As silicon (Si) technology advances to 3 nm node and beyond, vertically stacking in 3D is considered as the primary choice to increase the density of transistors per unit area for better chip performance. Therefore, looking for new materials capable of replacing Si in back-end-of-line (BEOL) compatible monolithic 3D (M3D) integration has become one of the most important topics in the current field of electronic devices. Recent developed atomic layer deposition (ALD) deposited indium oxide (In2O3) field-effect transistors (FETs) have realized excellent electrical performance including field effect mobility over 100 cm2/V·s, on/off ratio up to 1017 and on-state current (ION) over 2.5 mA/μm in nanometer thin In2O3 FETs, providing promising prospect for next generation electronics. In this thesis, four main In2O3 related topics are discussed to examine the practicality of ALD In2O3 as channel material in BEOL compatible applications. First, the bias stability of planar In2O3 transistors and the effect of tin doping are studied. Second, gate-all-around (GAA) In2O3 FETs are implemented to improve ION up to record high 20 mA/μm, and its reliability is systematically measured and analyzed. Third, multilayer In2O3 FETs are constructed to investigate the possibility of vertical stacking. Last, vertical full oxide transistors with In2O3 gate are demonstrated to prove the feasibility of potential 3D integration.

description: The measurement of pion source radii in Pb-Pb collisions with the ALICE experiment at LHC is presented. By the analysis of Bose-Einstein enhancement in the correlation function of identical pions information on the size and evolution of the source region in space-time can be obtained. The source radii observed at LHC are larger than at RHIC, approximately scaling with the cube root of the particle multiplicity. A decrease of source radii with increasing pair momentum, indicating a collective expansion of the medium, was observed at RHIC and SPS and is also expected at LHC energies. The ALICE data confirm this and provide strict constraints on dynamical models describing the medium expansion. The results suggest that the created fireball has a higher temperature and a longer lifetime as compared to lower energies.

description: We present explicit expressions for the high-frequency asymptotic behavior of electron self-energy of general quantum impurity models, which may be useful for improving the convergence of dynamical mean-field calculations and for the analytic continuation of the electron self-energy. We also give results, expressed in more physical terms, for the two-orbital and three-orbital rotationally invariant Slater-Kanamori interactions, in order to facilitate calculations of transition metal oxides.

The impact of multi-stakeholder planning and design processes on large-scale residential developments : an evaluation of the Rodgers Creek Area development, British Columbia
Creators: name: Coull, Renee Katherine
Publisher: name: University of British Columbia
Year: 2010

description: This thesis evaluates the planning and design process for the Rodgers Creek development in West Vancouver, British Columbia. The site spans 215-acres and is part of a series of residential projects by British Pacific Properties (BPP). The planning and design process for the Rodgers Creek Area Development Plan (ADP) began in 2005 was approved in 2008. The approval of the development within the lifecycle of Council (3 years) was a critical underlying factor in the process. The ADP accommodates 736 dwelling units in six neighbourhoods connected by a unique mountain pathway allowing for the preservation of 55% of green space on the site. The analysis and evaluation of the planning and design process is based on a variety of qualitative and quantitative data including academic and practitioner sources as well as in-depth interviews with key stakeholders. The Rodgers Creek planning and design process is path-breaking and inventive in its use of a high level of public participation. The process was multi-layered and included detailed background work, integrated technical sessions, a unique project-specific working group comprising unpaid industry advisors and innovative review, evaluation and implementation tools. The process was based on transparency, openness, trust, flexibility, inclusiveness and collaboration. By involving all stakeholders, it bridged the gap between the community, local government and the private sector. The participatory approach led to the development of a plan that produced a more sustainable model of development that was accepted by the community and easy to endorse for elected officials. Urban development problems arising from conventional processes call for new planning and design processes. The results of the evaluation suggest that better processes may lead to better outcomes. The Rodgers Creek development points to the importance of engaging stakeholders and forming an integrated team. The concept of a tailored working group to respond to the characteristics of the development could be transported to other large-scale residential developments to produce better forms of development. The success of the Rodgers Creek planning and design process should provide greater confidence for future stakeholders to engage in a similar process.

description: We construct a statistical model that reproduces the BPS partition function of D4-D2-D0 bound states on a class of toric Calabi-Yau three-folds. The Calabi-Yau three-folds we consider are obtained by adding a compact two-cycle to $A_{N-1}$-ALE $\times \mathbb{C}$. We show that in the small radii limit of the Calabi-Yau the D4-D2-D0 partition function is correctly reproduced by counting the number of triangles and parallelograms.

description: Captchas are used as a security mechanism on the web to distinguish human users from automated programs. However, existing captchas are not well-adapted to mobile devices and may lead users to abandon tasks. Although Web developers have many available captchas, they lack the tools to evaluate if these captchas are suitable for their mobile site. In this paper, we present domain specific usability heuristics for evaluating captchas on smartphones. To assess effectiveness, we compared our proposed heuristics against Nielsen's during evaluations of four captcha schemes on smartphones. The custom heuristics revealed more major problems and more detailed feedback on the problems than Nielsen's.

description: Сталий розвиток цивільної авіації, що визначає екологічні та енергетичні пріоритети сучасних європейських аеропортів, є запорукою високої конкурентоздатності компаній на ринку авіаперевезень. В аеропортах існують типові недоліки експлуатації будівель та споруд, які призводять до значних необґрунтованих енергетичних втрат. У більшості випадків неефективність кінцевого споживання енергії не може бути виявлена обслуговуючим персоналом внаслідок недосконалого моніторингу, збору, обробки, аналізу та документування даних з енергоспоживання та недостатнього рівня взаємозв’язку між окремими службами. У зв’язку із цим існує значна кількість напрямів енерговикористання при функціонуванні аеропортів, ефективне і економічне управління якими потребує використання нових методологічних принципів та інноваційних ІКТ. Покращення рівня управління та якості прийняття рішень сприятиме підвищенню ефективності експлуатації та зростанню конкурентоспроможності як окремих підприємств цивільної авіації, так і галузі у цілому. Мета доповіді - трансфер сучасних світових методологій сталої авіації для системного підвищення енергоефективності функціонування аеропортів України, зменшення техногенного впливу на навколишнє середовище та покращення рівня авіаційних послуг.

description: The main result is the identification of the orthogonal complement of the subalgebra of conformal vector field inside the algebra of all vector fields of a compact flat 2-manifold. As a fundamental tool, the complete Hodge decomposition for manifold with boundary is used. The identification allows the derivation of governing differential equations for variational problems on the space of conformal vector fields. Several examples are given. In addition, the paper also gives a review, in full detail, of already known vector field decompositions involving subalgebras of volume preserving and symplectic vector fields.

description: This work presents a design space in which personal devices are used as a means to facilitate "socially safe", ad-hoc interaction with large public displays. Unlike most existing work that focuses on facilitating content placement and transfer, this approach aims at minimizing the effort required to initiate, sustain, and withdraw from interaction with a large public display, and to communicate these capabilities to passersby. We identify barriers hindering this process, and offer advice on overcoming them based on existing work and our own experiences with these displays. We illustrate how this design concept can be applied, and motivate applications in other domains.

description: We perform quantum tomography on one-dimensional polariton condensates, spontaneously occurring in linear disorder valleys in a CdTe planar microcavity sample. By the use of optical interferometric techniques, we determine the first-order coherence function and the amplitude and phase of the order parameter of the condensate, providing a full reconstruction of the single particle density matrix for the polariton system. The experimental data are used as input to theoretically test the consistency of Penrose-Onsager criterion for Bose-Einstein condensation in the framework of nonequilibrium polariton condensates. The results confirm the pertinence and validity of the criterion for a non equilibrium condensed gas.
