description: The care of wounds (broadly defined as any break in the surface of the skin) is considered a foundational component of nursing knowledge. Whilst most wounds resolve with minimal intervention, today’s aging population and rise in chronic disease have seen a rapid escalation in the number of people living with wounds that are challenging to heal. Nurses have played an integral part in initiatives to address the identified burden of chronic wounds. Efforts centred on developing evidence-based protocols intended to simplify selection of new wound-related technologies expected to improve clinical outcomes. In contrast to these expectations, anecdotal evidence, a limited number of published critiques and a recent focus in the literature on patient “wellbeing” suggest that wound care may be a contested place of nursing practice. This research interrogates the discourse of “advanced wound care” that presupposes wound healing as a linear, predictable event dependent on objective, quantifiable outcome measures. It troubles standardized approaches to wound care that require nurses to focus on physical characteristics of wounds rather than patients’ experience of living with a wound. Developed as an institutional ethnography, the study provided a way to articulate tensions that arise for nurses working in outpatient wound clinics. My analysis began in descriptions of everyday wound work. By empirically tracing links embedded in the textual records clinic nurses complete I explicate how biophysiological models organize nurses to practice as though wounds can be abstracted from the individuals living with them. This problem is amplified when translated into the algorithmic decision-making tools of an integrated health system wherein patients are managed as cases, referred to others for intervention, and provided with information to self-manage their care. I show how, as clinic nurses participate in the ruling relations of case management, their consciousness of what wound care is and how they are able to respond to their patients has been organized in line with managerial priorities. These findings call into question the foundations on which today’s wound care knowledge is built and open up for future dialogue and research the work of nurses and others committed to the care of people with chronic wounds.
Kernel-phases for high-contrast detection beyond the resolution limit

description: The detection of high contrast companions at small angular separation appears feasible in conventional direct images using the self-calibration properties of interferometric observable quantities. In the high-Strehl regime, available from space borne observatories and using AO in the mid-infrared, quantities comparable to the closure-phase that are used with great success in non-redundant masking inteferometry, can be extracted from direct images, even taken with a redundant aperture. These new phase-noise immune observable quantities, called Kernel-phases, are determined a-priori from the knowledge of the geometry of the pupil only. Re-analysis of HST/NICMOS archive and other ground based AO images, using this new Kernel-phase algorithm, demonstrates the power of the method, and its ability to detect companions at the resolution limit and beyond.

description: Previous research has highlighted the importance of strong heterogeneity for the successful evolution of cooperation in games governed by pairwise interactions. Here we determine to what extent this is true for games governed by group interactions. We therefore study the evolution of cooperation in the public goods game on the square lattice, the triangular lattice and the random regular graph, whereby the payoffs are distributed either uniformly or exponentially amongst the players by assigning to them individual scaling factors that determine the share of the public good they will receive. We find that uniformly distributed public goods are more successful in maintaining high levels of cooperation than exponentially distributed public goods. This is not in agreement with previous results on games governed by pairwise interactions, indicating that group interactions may be less susceptible to the promotion of cooperation by means of strong heterogeneity as originally assumed, and that the role of strongly heterogeneous states should be reexamined for other types of games.

title: Intermodal Open Spaces. An analysis of inner-city mobility stations in the Rhine-Main region
Creators: name: Halblaub Miranda, Marianne
Publisher: name: UNSPECIFIED
Year: 2023

description: Reducing private motorised traffic (PMT) and its resulting environmental pollution in favour of multi- and intermodal environmentally friendly mobility is essential for the development of sustainable cities. In addition to reducing PMT, intermodal mobility systems address individual mobility needs by integrating active modes such as walking and cycling, with public transport and sharing initiatives, such as car and bike sharing. This dissertation examines current planning strategies aimed at promoting intermodal mobility in urban areas, focusing on one approach presented as Intermodal Open Spaces (IOS). IOS are urban open spaces with embedded mobility nodes that support multi- and intermodality and are integrated into the urban context in such a way that an array of activities - beyond the provision of mobility services - can take place in them. Based on an empirical study in five selected cities in the Rhine-Main region, a typology of IOS is presented. The typology is based on the spatial interaction between the morphology of open spaces and the flow of active and motorised traffic. Structured by location and integration, spatial configuration and morphology, and activities and amenity quality, the case studies present spatially and programmatically disaggregated examples of IOS. Methods include desktop and on-site mapping of features identified through literature review, such as morphology, configuration, road network, visual integration, land use and others. This doctoral dissertation serves as a theoretical prelude to the definition of IOS and contributes to the debate on the spatial design and planning of multifunctional mobility stations in urban studies and transport planning.

description: The effect of two- and three-body interactions on the modulation instability (MI) domain formation of a spin-orbit (SO) and Rabi-coupled Bose-Einstein condensate is studied within a quasi-one-dimensional model. To this aim, we perform numerical and analytical investigations of the associated dispersion relations derived from the corresponding coupled Gross-Pitaevskii equation. The interplay between the linear (SO and Rabi) couplings with the nonlinear cubic-quintic interactions are explored in the mixture, considering miscible and immiscible configurations, with a focus on the impact in the analysis of experimental realizations with general binary coupled systems, in which nonlinear interactions can be widely varied together with linear couplings.

description: This thesis examines the roles played by history in Charles Peirce’s philosophy of science. History is seen to have two roles. First, it contributes to the philosophy of science: in examining the history of science we are able to learn about science and scientific progress. In this way, studying history can teach us about inquiry itself. Secondly, history is the subject of the philosophy of science. The methods of inquiry learned about and developed in the philosophy of science should be applied to historical inquiries. In this way, history contributes to philosophy of science, and historians (among other scientists) benefit from this contribution.
Time-varying exposure subject to misclassification : bias characterization and adjustment
Creators: name: Cormier, Eric
Publisher: name: University of British Columbia
Year: 2010

description: Measurement error occurs frequently in observational studies investigating the relationship between exposure variables and a clinical outcome. Error-prone observations on the explanatory variable may lead to biased estimation and loss of power in detecting the impact of an exposure variable. When the exposure variable is time-varying, the impact of misclassification is complicated and significant. This increases uncertainty in assessing the consequences of ignoring measurement error associated with observed data, and brings difficulties to adjustment for misclassification. In this study we considered situations in which the exposure is time-varying and nondifferential misclassification occurs independently over time. We determined how misclassification biases the exposure outcome relationship through probabilistic arguments and then characterized the effect of misclassification as the model parameters vary. We show that misclassification of time-varying exposure measurements has a complicated effect when estimating the exposure-disease relationship. In particular the bias toward the null seen in the static case is not observed. After misclassification had been characterized we developed a means to adjust for misclassification by recreating, with greatest likelihood, the exposure path of each subject. Our adjustment uses hidden Markov chain theory to quickly and efficiently reduce the number of misclassified states and reduce the effect of misclassification on estimating the disease-exposure relationship. The method we propose makes use of only the observed misclassified exposure data and no validation data needs to be obtained. This is achieved by estimated switching probabilities and misclassification probabilities from the observed data. When these estimates are obtained the effect of misclassification can be determined through the characterization of the effect of misclassification presented previously. We can also directly adjust for misclassification by recreating the most likely exposure path using the Viterbi algorithm. The methods developed in this dissertation allow the effect of misclassification, on estimating the exposure-disease relationship, to be determined. It accounts for misclassification by reducing the number of misclassified states and allows the exposure-disease relationship to be estimated significantly more accurately. It does this without the use of validation data and is easy to implement in existing statistical software.

description: Data augmentation is now an essential part of the image training process, as it effectively prevents overfitting and makes the model more robust against noisy datasets. Recent mixing augmentation strategies have advanced to generate the mixup mask that can enrich the saliency information, which is a supervisory signal. However, these methods incur a significant computational burden to optimize the mixup mask. From this motivation, we propose a novel saliency-aware mixup method, GuidedMixup, which aims to retain the salient regions in mixup images with low computational overhead. We develop an efficient pairing algorithm that pursues to minimize the conflict of salient regions of paired images and achieve rich saliency in mixup images. Moreover, GuidedMixup controls the mixup ratio for each pixel to better preserve the salient region by interpolating two paired images smoothly. The experiments on several datasets demonstrate that GuidedMixup provides a good trade-off between augmentation overhead and generalization performance on classification datasets. In addition, our method shows good performance in experiments with corrupted or reduced datasets.

description: When a micrometer-sized fluid droplet is illuminated by a laser pulse, there is a fundamental distinction between two cases. If the pulse is short in comparison with the transit time for sound across the droplet, the disruptive optical Abraham-Minkowski radiation force is countered by electrostriction and the net stress is compressive. In contrast, if the pulse is long on this scale, electrostriction is cancelled by elastic pressure and the surviving term of the electromagnetic force, the Abraham-Minkowski force, is disruptive and deforms the droplet. Ultrashort laser pulses are routinely used in modern experiments, and impressive progress has moreover been made on laser manipulation of liquid surfaces in recent times, making a theory for combining the two pertinent. We analyze the electrostrictive contribution analytically and numerically for a spherical droplet.

Evaluating the Potential of Reflection-Based Waveform Inversion

description: Full waveform inversion (FWI) is a powerful tool to build high-resolution velocity models, from recorded seismic data. However, a major issue with FWI is that it fails to reconstruct the low-wavenumber components of the velocity model in the absence of low-frequency information in the data. Generally, for a limited-offset acquisition geometry, deep targets are only sampled by reflected waves with narrow scattering angles, which makes such failure inevitable. In this thesis, I point out the limitation of conventional FWI when applied to reflection data and review, implement and analyze an alternative approach to overcome this limitation called reflection-based waveform inversion (RWI). The new waveform inversion formalism relies on decomposing the subsurface model into a background part that I seek to resolve, and a reflectivity part that is assumed to be known. Separating the decoupled velocity model into long- and short-wavelength components permits us to extract the contribution of the reflected data to the background part of the velocity model. In this thesis, I show that RWI retrieves the long-wavelength information from seismic reflections where FWI fails, and that it is the concept of modeling by seismic demigration that enables this retrieval. Also, I show that modeling by seismic demigration imposes limitations to RWI, as it removes any amplitude versus offset (AVO) information and mandates reflections-only recorded data, which prevents the usage of diving waves, refractions and direct arrivals. I show that applying source-receiver illumination compensation to the gradient enhances the contributions of deeper reflections and speeds up the convergence of the inversion. Also, I show that the choice of having the source function in the wave equation as a forcing term or as a boundary value problem (BVP) has a major impact on the inversion results and that the inversion is highly sensitive to the way the source function is treated in the wave equation. All the tools used in this thesis to generate synthetic data, wavefields, and to carry the waveform inversion were developed from scratch using Python. The finite-difference engine was validated by analyzing the AVO response for simple models, by examining reverse time migration results, and by testing the codes on FWI. The RWI code was validated with previously established results.
Visualizing and Using Colour in Information Visualization

description: Colour is an important part of how most of us see and perceive the world. Colour impacts our day-to-day lives whether it is colours we see in nature or colours reproduced on electronic displays. While the average American now spends eight hours a day looking at some form of electronic display, reproducing and using colour effectively on electronic displays has remained a challenge. Using colour well on computer displays has been of special importance to information visualization researchers and practitioners, artists, and designers who use colour in their work to express ideas, concepts, emotion, data, and information. In the field of information visualization, colour is commonly used for the purposes of encoding of additional dimensions of data. Knowing which colour choices to make when encoding data in information visualizations systems and information graphics is often difficult and often comes down to a case of trial and error or aesthetic choices by the designer. In this thesis, I address issues of digital colour use including, a) how can people better understand the colour choices of artists and designers by visualizing the colour data extracted from large digital image sets, b) how can we visualize abstract concepts and ideas using relevant colour information, and c) how can we computationally help inform visualization designers to know more about the accessibility of their colour choices and assist in balancing aesthetic and perceptually different colour choices in their visualizations. I present a novel visualization approach and two digital tools, ColourVis and ColourSafe that address these outstanding research questions. Through ColourVis, I offer an exploration and comparison tool for individual paintings, groups of paintings and trends in colour usage over time. ColourSafe helps inform information visualization designers, artists, and researchers about the colours they use in their visualizations. By using such tools, designers and artists are more informed about the colour palettes and choices making up large groups of images and be able to choose colours that are both aesthetically pleasing and accessible to a wide audience in their own work.

description: Astronomical transients are intrinsically interesting things to study. Fast optical transients (microsecond timescale) are a largely unexplored field of optical astronomy mainly due to the fact that large optical telescopes are oversubscribed. Furthermore, most optical observations use instruments with integration times on the order of seconds and are thus unable to resolve fast transients. Current-generation atmospheric Cherenkov gamma-ray telescopes, however, have huge collecting areas (e.g., VERITAS, which consists of four 12-m telescopes), larger than any existing optical telescopes, and time is typically available for such studies without interfering with gamma-ray observations. The following outlines the benefits of using a Cherenkov telescope to detect optical transients and the implementation of the VERITAS Transient Detector (TRenDy), a dedicated multi-channel photometer based on field-programmable gate arrays. Data are presented demonstrating the ability of TRenDy to detect transient events such as a star passing through its field of view and the optical light curve of a pulsar.

description: This letter considers cascaded model predictive control (MPC) as a computationally lightweight method for controlling a tandem-rotor helicopter. A traditional single MPC structure is split into separate outer and inner-loops. The outer-loop MPC uses an $SE_2(3)$ error to linearize the translational dynamics about a reference trajectory. The inner-loop MPC uses the optimal angular velocity sequence of the outer-loop MPC to linearize the rotational dynamics. The outer-loop MPC is run at a slower rate than the inner-loop allowing for longer prediction time and improved performance. Monte-Carlo simulations demonstrate robustness to model uncertainty and environmental disturbances. The proposed control structure is benchmarked against a single MPC algorithm where it shows significant improvements in position and velocity tracking while using significantly less computational resources.

description: Natural convection in porous media is a phenomenon in which the unstable setting of fluid layers leads to the formation of convective currents and is very important to different aspects of science and engineering including chemo-hydrodynamics, geological storage of CO2, and solvent-aided thermal recovery from bitumen reservoirs. This thesis analyzes the effect of viscosity variation in single and double diffusive convection using linear stability analysis and nonlinear numerical simulation. Universal scaling relations were developed to predict the onset of convective instabilities and their initial wavelengths. The developed numerical model was validated using a number of benchmark problems. The model results were compared with stability analysis predictions and good agreement was observed. Finally, linear stability analysis was employed to optimize the selection of n-alkane solvents in solvent-aided thermal recovery methods from bitumen reservoirs.

description: An exactly solvable cluster spin model with three-spin interaction couplings J_x (for XZX spin components) and J_y (for YZY spin components) in the presence of a transverse magnetic field $h$ for a spin chain is investigated. For $h=0$, and with only one nonzero interaction strength, the ground state is the cluster state. Through the Jordan-Wigner fermion mapping, the odd sites and the even sites form two separate transverse-XY chains, connected only through the boundary terms. Consequently, all measures of quantum correlations for nearest neighbour spins, the concurrence, the quantum mutual information and the quantum discord are all zero in the ground state. The dynamics is spin conserving for J_y=J_x, exhibiting a line of critical points for |h/J_x| < 2, with an uncorrelated direct product ground state for |h/J_x|>2. There are several quantum critical points in the parameter space, with multi-fold degenerate ground states. The magnetisation and the global entanglement measure exhibit strong singular features for the spin conserving case. The next-neighbour quantum correlation measures are investigated analytically, which exhibit singular features in the vicinity of degeneracy critical points. The $J_y$- and $h$- derivatives of the concurrence exhibit singular peak behaviour near the degeneracy critical points, except in the spin conserving case where the derivatives are zero.

description: The high rates of multi-parton interactions at the LHC can provide a unique opportunity to study the multi-parton structure of the hadron. To this purpose high energy collisions of protons with nuclei are particularly suitable. The rates of multi-parton interactions depend in fact both on the partonic multiplicities and on the distributions of partons in transverse space, which produce different effects on the cross section in pA collisions, as a function of the atomic mass number A. Differently with respect to the case of multi-parton interactions in pp collisions, the possibility of changing the atomic mass number provides thus an additional handle to distinguish the diverse contributions. Some relevant features of double parton interactions in pD collisions have been discussed in a previous paper. In the present paper we show how the effects of double and triple correlation terms of the multi-parton structure can be disentangled, by comparing the rates of multiple parton interactions in collisions of protons with D, Tritium and 3He.

description: The rotations of the polarization angle (PA) with time (energy) can lead to the depolarization of the time-integrated (energy-integrated) polarization. However, we don't know how and when it will rotate. Here, we consider the magnetic reconnection model to investigate the polarizations, especially the PA rotations of GRB prompt emission. For the large-scale ordered aligned magnetic field configuration, we find that PAs will evolve with time (energy) for off-axis observations. Our studies show that the rotations of the PAs are due to the changes of the ``observed shape'' of the emitting region (before averaged). We apply our models to the single pulse burst of GRB 170101A and GRB 170114A with time-resolved PA observations. We find it can interpret the violent PA variation of GRB 170101A. The model could not predict the twice $90^{\circ}$ PA changes in GRB 170114A. Detailed model should be considered.

The Fast Downward Planning System
Creators: name: Helmert, M.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: Fast Downward is a classical planning system based on heuristic search. It can deal with general deterministic planning problems encoded in the propositional fragment of PDDL2.2, including advanced features like ADL conditions and effects and derived predicates (axioms). Like other well-known planners such as HSP and FF, Fast Downward is a progression planner, searching the space of world states of a planning task in the forward direction. However, unlike other PDDL planning systems, Fast Downward does not use the propositional PDDL representation of a planning task directly. Instead, the input is first translated into an alternative representation called multi-valued planning tasks, which makes many of the implicit constraints of a propositional planning task explicit. Exploiting this alternative representation, Fast Downward uses hierarchical decompositions of planning tasks for computing its heuristic function, called the causal graph heuristic, which is very different from traditional HSP-like heuristics based on ignoring negative interactions of operators. In this article, we give a full account of Fast Downwards approach to solving multi-valued planning tasks. We extend our earlier discussion of the causal graph heuristic to tasks involving axioms and conditional effects and present some novel techniques for search control that are used within Fast Downwards best-first search algorithm: preferred operators transfer the idea of helpful actions from local search to global best-first search, deferred evaluation of heuristic functions mitigates the negative effect of large branching factors on search performance, and multi-heuristic best-first search combines several heuristic evaluation functions within a single search algorithm in an orthogonal way. We also describe efficient data structures for fast state expansion (successor generators and axiom evaluators) and present a new non-heuristic search algorithm called focused iterative-broadening search, which utilizes the information encoded in causal graphs in a novel way. Fast Downward has proven remarkably successful: It won the "classical (i.e., propositional, non-optimising) track of the 4th International Planning Competition at ICAPS 2004, following in the footsteps of planners such as FF and LPG. Our experiments show that it also performs very well on the benchmarks of the earlier planning competitions and provide some insights about the usefulness of the new search enhancements.

description: This thesis analyses Ontario’s Treaty 9 role and the significance of the 1905 Treaty 9 diary written by its Commissioner, Daniel George MacMartin. Ontario’s Treaty 9 involvement resulted from its decades-long co-sovereigntist campaign from 1867-1905. The diary is a unique historical document that fuses both oral and written records of the 1905 Treaty 9 negotiations. It confirms that Treaty 9 First Nations were given oral assurances they could continue hunting, fishing and trapping throughout their traditional territory. This is now a constitutionally entrenched treaty right. MacMartin’s appointment as Ontario’s Treaty 9 Commissioner is explained as reflecting a well-established operative dimension of Ontario political culture. It is concluded that George MacMartin brought honour to the Crown in 1905 in recording and preserving his observations about the Treaty 9 negotiation meetings in his diary and established a model for Canada’s governments to now emulate in dealings with Canada’s First Nations.
Molecular and pharmacological characterization of mutant (F92A) caveolin-1 : a direction towards increasing nitric oxide bioavailability
Creators: name: Sharma, Arpeeta
Publisher: name: University of British Columbia
Year: 2010

description: Nitric Oxide (NO) produced by the endothelium is a critical mediator of vascular function and plays an important role in the protection against various cardiovascular diseases1. In fact, a central feature of most cardiovascular diseases is reduced bioavailability of NO resulting from impaired endothelial function. Consequently, therapies that improve NO synthesis and availability in disease settings are relevant. Endothelial nitric oxide synthase (eNOS) is a membrane enzyme expressed exclusively in vascular endothelial cells and is responsible for NO production. Improper regulation of the enzyme results in production of eNOS-derived superoxide anion (O₂₋) instead of NO. O₂₋ is an oxidative stress mediator and scavenges NO, thereby contributing to lowered NO bioavailability. Extensive research has demonstrated a number of factors involved in positively regulating eNOS activity. However, one of the few proteins that bind to eNOS under basal conditions and inhibit NO release is Caveolin-1 (Cav-1), the major coat protein of plasma membrane lipid-enriched invaginations known as caveolae². Recently, it was demonstrated that a single amino acid substitution of the Cav-1 protein, mutant known as F92A Cav-1, is unable to inhibit eNOS³. Furthermore, preliminary data indicates that high expression of F92A Cav-1 can increase basal NO release. Due to the significance of NO in vascular function, the current work explores the possible mechanisms by which F92A Cav-1 potentiates eNOS activity and NO release. We report that F92A Cav-1 preserves the unique properties of Cav-1, including targeting to caveolae and forming high molecular weight oligomers, which are essential for caveolae organelle biogenesis. Moreover, F92A Cav-1 still retains the ability to bind to eNOS without altering its subcellular localization, indicating that F92A Cav-1 can prevent eNOS binding to endogenous Cav-1, which could rationalize the increased NO release observed. Lastly, we provide evidence that over-expression of F92A Cav-1 reduces the release of basal O₂₋ in endothelial cells as compared to WT Cav-1, revealing another potential positive effect of the mutant Cav-1.

description: Multimodal Sarcasm Explanation (MuSE) is a new yet challenging task, which aims to generate a natural language sentence for a multimodal social post (an image as well as its caption) to explain why it contains sarcasm. Although the existing pioneer study has achieved great success with the BART backbone, it overlooks the gap between the visual feature space and the decoder semantic space, the object-level metadata of the image, as well as the potential external knowledge. To solve these limitations, in this work, we propose a novel mulTi-source sEmantic grAph-based Multimodal sarcasm explanation scheme, named TEAM. In particular, TEAM extracts the object-level semantic meta-data instead of the traditional global visual features from the input image. Meanwhile, TEAM resorts to ConceptNet to obtain the external related knowledge concepts for the input text and the extracted object meta-data. Thereafter, TEAM introduces a multi-source semantic graph that comprehensively characterize the multi-source (i.e., caption, object meta-data, external knowledge) semantic relations to facilitate the sarcasm reasoning. Extensive experiments on a public released dataset MORE verify the superiority of our model over cutting-edge methods.

Can a Value-Based Writing Task Reduce a Self-Discrepant Body Image?
Creators: name: Lester, Chantal

subject: Body Image

description: The purpose of this research study was to examine the relationship between body self-discrepancy, as measured by the Body Image Ideals Questionnaire (BIQ; Cash & Szymanski, 1995), the Body Mass Index Silhouettes Matching Test (BMI-SMT; Peterson, Ellenberg, & Crossman, 2003) and a self-affirmation manipulation. The sample consisted of 80 female undergraduate university students recruited through class announcements and posters. Participants were randomly assigned to either an experimental or control condition and were each individually guided through the experiment. All participants completed (a) pre-test questionnaires, (b) an exposure to media images depicting thin female models, (c) either a self-affirming or a neutral writing task, and (d) post-test measures. The data was analyzed using descriptive statistics and repeated measures analysis of variance. It was hypothesized that participants in the experimental group would experience a greater decrease in body self-discrepancy at post-test compared to those in the control group. The results suggested that women in both conditions reported a significant increase in body self-discrepancy scores on the post BIQ measure, and endorsed wanting to attain smaller silhouettes (BMI-SMT measure) at both pre and post. Although previous studies have found that self-affirmations have had a psychological buffering effect and led to a reduction in reported body dissatisfaction scores (e.g., Armitage, 2012; Bucchianeri & Corning, 2012), this particular study did not show a decrease in body self-discrepancy scores. Since this study uniquely investigated a particular component of body image concern (body self-discrepancy) in relation to a self-affirming manipulation, it is likely that more research is needed to further understand this facet of body image.
A T-Matrix Calculation for in-Medium Heavy-Quark Gluon Scattering

description: The interactions of charm and bottom quarks in a Quark-Gluon Plasma (QGP) are evaluated using a thermodynamic 2-body T-matrix. We specifically focus on heavy-quark (HQ) interactions with thermal gluons with an input potential motivated by lattice-QCD computations of the HQ free energy. The latter is implemented into a field-theoretic ansatz for color-Coulomb and (remnants of) confining interactions. This, in particular, enables to discuss corrections to the potential approach, specifically hard-thermal-loop corrections to the vertices, relativistic corrections deduced from pertinent Feynman diagrams, and a suitable projection on transverse thermal gluons. The resulting potentials are applied to compute scattering amplitudes in different color channels and utilized for a calculation of the corresponding HQ drag coefficient in the QGP. A factor of ~2-3 enhancement over perturbative results is obtained, mainly driven by the resummation in the attractive color-channels.
Dynamic Role Lease Authorization Protocol for a Distributed Computing System

description: A distributed computing system, such as a Grid, could be a very dynamic environment and the user groups are most likely become highly diverse. A user group could be formed by the users of different networks, organizations, or administrative-domains with different hardware/software infrastructures and managerial policies. Handling requests from a wide range of users from different domains becomes a challenge when attempting to accommodate all the differences. Service providers find it impossible to track all users (the number of users could be potentially very large) in a Grid. Therefore, an access control mechanism that provides users appropriate access to the resources in a dynamic environment is required. Role Based Access Control (RBAC) models have been demonstrated to be an effective and efficient approach for an administrator to manage accesses in a computing system. Much has been done to adapt the RBAC concept to Grids and focus on the authorization and verification of the dynamic factors or contexts of a user, such as time, location, rank, etc. Some applications also allow administrators to change the policies during the authorization process, but they did not handle the authorization in real-time and on-demand manner in a Grid. It is a critical authorization requirement for a dynamic environment. Therefore, this problem motivated us to develop a new dynamic authorization protocol, Dynamic Role Lease Authorization (DRLA) that is suitable for a dynamic distributed computing environment.
Optically Induced Polarization and Depolarization of an Electron Spin in a Nitrogen-Vacancy Center of Diamond Nano-crystals

description: Pulsed laser excitation causes the luminescence of Nitrogen Vacancy centers in diamond to unexpectedly decrease with increasing pulse energy. This decrease is observed in both the negatively charged and neutral centers and is caused by shortening of the luminescence lifetimes of the centers of both types. In darkness, the luminescence does not show any recovery on a time scale of 10 microseconds but as little as three low-intensity pulses can return the luminescence to its previous, brighter state. An external magnetic field reduces the magnitude of the effect. A possible mechanism for these phenomena based on optical polarisation and depolarisation of an electronic spin is proposed.

description: We propose the design of a space-variant Wien filter for electron beams that induces a spin half-turn and converts the corresponding spin angular momentum variation into orbital angular momentum of the beam itself by exploiting a geometrical phase arising in the spin manipulation. When applied to a spatially coherent input spin-polarized electron beam, such a device can generate an electron vortex beam, carrying orbital angular momentum. When applied to an unpolarized input beam, the proposed device, in combination with a suitable diffraction element, can act as a very effective spin-polarization filter. The same approach can also be applied to neutron or atom beams.
