description: Over the last decade, the Imaging Air Cerenkov technique has proven itself to be an extremely powerful means to study very energetic gamma-radiation from a number of astrophysical sources in a regime which is not practically accessible to satellite-based instruments. The further development of this approach in recent years has generally concentrated on increasing the density of camera pixels, increasing the mirror area and using multiple telescopes. Here we present a practical method to substantially improve the sensitivity of Atmospheric Cerenkov Telescopes using wide-field cameras with a relatively course density of photomultiplier tubes. The 2-telescope design considered here is predicted to be more than ~3 times more sensitive than existing/planned arrays in the regime above 300 GeV for continuously emitting sources; up to ~10 times more sensitive for hour-scale emission (relevant for episodic sources, such as AGN); significantly more sensitive in the regime above 10 TeV; and possessing a sky coverage which is roughly an order of magnitude larger than existing instruments. It should be possible to extend this approach for even further improvement in sensitivity and sky coverage.

description: Modern web applications often rely on third-party services to provide their functionality to users. The secure integration of these services is a non-trivial task, as shown by the large number of attacks against Single Sign On and Cashier-as-a-Service protocols. In this paper we present Bulwark, a new automatic tool which generates formally verified security monitors from applied pi-calculus specifications of web protocols. The security monitors generated by Bulwark offer holistic protection, since they can be readily deployed both at the client side and at the server side, thus ensuring full visibility of the attack surface against web protocols. We evaluate the effectiveness of Bulwark by testing it against a pool of vulnerable web applications that use the OAuth 2.0 protocol or integrate the PayPal payment system.

description: We show that porcine brain matter can be modelled accurately as a very soft rubber-like material using the Mooney-Rivlin strain energy function, up to strains as high as 60\%. This result followed from simple shear experiments performed on small rectangular fresh samples ($2.5$ cm$^3$ and $1.1$ cm$^3$) at quasi-static strain rates. They revealed a linear shear stress--shear strain relationship ($R^2> 0.97 $), characteristic of Mooney-Rivlin materials at large strains. We found that porcine brain matter is about 30 times less resistant to shear forces than a silicone gel. We also verified experimentally that brain matter exhibits the positive Poynting effect of nonlinear elasticity, and numerically that the stress and strain fields remain mostly homogeneous throughout the thickness of the samples in simple shear.

description: We report the first results from evolutions of a generic black-hole binary, i.e. a binary containing unequal mass black holes with misaligned spins. Our configuration, which has a mass ratio of 2:1, consists of an initially non-spinning hole orbiting a larger, rapidly spinning hole (specific spin a/m = 0.885), with the spin direction oriented -45 degrees with respect to the orbital plane. We track the inspiral and merger for ~2 orbits and find that the remnant receives a substantial kick of 454 km/s, more than twice as large as the maximum kick from non-spinning binaries. The remnant spin direction is flipped by 103 degrees with respect to the initial spin direction of the larger hole. We performed a second run with anti-aligned spins, a/m = +-0.5 lying in the orbital plane that produces a kick of 1830 km/s off the orbital plane. This value scales to nearly 4000 km/s for maximally spinning holes. Such a large recoil velocity opens the possibility that a merged binary can be ejected even from the nucleus of a massive host galaxy.

description: Computer vision algorithms performance are near or superior to humans in the visual problems including object recognition (especially those of fine-grained categories), segmentation, and 3D object reconstruction from 2D views. Humans are, however, capable of higher-level image analyses. A clear example, involving theory of mind, is our ability to determine whether a perceived behavior or action was performed intentionally or not. In this paper, we derive an algorithm that can infer whether the behavior of an agent in a scene is intentional or unintentional based on its 3D kinematics, using the knowledge of self-propelled motion, Newtonian motion and their relationship. We show how the addition of this basic knowledge leads to a simple, unsupervised algorithm. To test the derived algorithm, we constructed three dedicated datasets from abstract geometric animation to realistic videos of agents performing intentional and non-intentional actions. Experiments on these datasets show that our algorithm can recognize whether an action is intentional or not, even without training data. The performance is comparable to various supervised baselines quantitatively, with sensible intentionality segmentation qualitatively.

description: We propose schemes for entanglement concentration and purification for qubit systems encoded in flying atomic pairs. We use a cavity-quantum electrodynamics setting as the paradigmatic scenario within which our proposals can be implemented. Maximally entangled pure states of qubits can be produced as a result of our protocols. In particular, the concentration protocol yields Bell states with the largest achievable theoretical probability while the purification scheme produces arbitrarily pure Bell states. The requirements for the implementation of these protocols are modest, within the state of the art, and we address all necessary steps in two specific set-ups based on experimentally mature microwave technology.

description: In curvaton-type models, observable non-gaussianity of the curvature perturbation would come from a contribution of the form $(δσ)^2$, where $δσ$ is gaussian. I analyse this situation allowing $δσ$ to be scale-dependent. The actual curvaton model is considered in more detail than before, including its cosmic uncertainty and anthropic status. The status of curvaton-type models after WMAP year three data is considered.

Hybrid constraint space position/force control
Creators: name: Wong, Roger
Publisher: name: University of British Columbia
Year: 2009

description: This thesis documents the conceptual development of the author's contribution, the hybrid constraint space position/force controller for robotic manipulator control in constrained environments. This method is built upon a constraint space dynamic model, where the model parameters are displacement along the constraint trajectory and normal force between the manipulator end-effector and environment. This dynamic model is constructed by transforming conventional joint space manipulator dynamics into their constraint space equivalents through the application of mapping functions, which relate differential displacements and velocities in the constraint space coordinate system to the joint space coordinate system. Conventional PD controllers may then be applied to the simplified dynamic structure of the constraint space equations of motion, in order to produce a vector of manipulator joint torques which will satisfy both position and force requirements along the environmental constraint. Actuator constraints and momentum compensating techniques are also used to ensure that the position and force control problems are completely decoupled from one another. This modelling technique is then applied to the control problem for a two degree of freedom prismatic robot as an illustrative example. Simulation of this specific controller is carried out with respect to three different constraint surfaces, a planar, a concave circular and a convex circular environment. The results of these simulations show that the hybrid constraint space controller provides excellent position and force trajectory tracking for the planar case study. This thesis is intended to be the forerunner to future work which will develop in detail, the application of hybrid constraint space control to highly nonlinear manipulator/constraint models.

description: We present high spatial resolution optical integral field spectroscopy of a collimated Herbig-Haro jet viewed nearly edge-on. Maps of the line emission, velocity centroid, and velocity dispersion were generated for the H$α$ and [S II] emission features from the inner collimated jet and exciting source region of the HH 34 outflow. The kinematic structure of the jet shows several maxima and minima in both velocity centroid value and velocity dispersion along the jet axis. Perpendicular to the flow direction the velocity decreases outward from the axis to the limb of the jet, but the velocity dispersion increases. Maps of the electron density structure were derived from the line ratio of [S II] 6731/6716 emission. We have found that the jet exhibits a pronounced ``striped'' pattern in electron density; the high $n_e$ regions are at the leading side of each of the emission knots in the collimated jet, and low $n_e$ regions in the down-flow direction. On average, the measured electron density decreases outward from the inner regions of the jet, but the highest $n_e$ found in the outflow is spatially offset from the nominal position of the exciting star. The results of our high spatial resolution optical integral field spectroscopy show very good agreement with the kinematics and electron density structure predicted by the existing internal working surface models of the HH~34 outflow.

description: An innovative scheme is proposed for the dynamic control of phase in two-dimensional laser beam array. It is based on a simple neural network that predicts the complex field array from the intensity of the induced scattered pattern through a phase intensity transformer made of a diffuser. Iterated phase corrections are applied on the laser field array by phase modulators via a feedback loop to set the array to prescribed phase values. A crucial feature is the use of a kind of reinforcement learning approach for the neural network training which takes account of the iterated corrections. Experiments on a proof of concept system demonstrated the high performance and scalability of the scheme with an array of up to 100 laser beams and a phase setting at 1/30 of the wavelength.

description: Adopting a joint approach towards state estimation and integrity monitoring results in unbiased integrity monitoring unlike traditional approaches. So far, a joint approach was used in Particle RAIM [l] for GNSS measurements only. In our work, we extend Particle RAIM to a GNSS-camera fused system for joint state estimation and integrity monitoring. To account for vision faults, we derive a probability distribution over position from camera images using map-matching. We formulate a Kullback-Leibler Divergence metric to assess the consistency of GNSS and camera measurements and mitigate faults during sensor fusion. The derived integrity risk upper bounds the probability of Hazardously Misleading Information (HMI). Experimental validation on a real-world dataset shows that our algorithm produces less than 11 m position error and the integrity risk over bounds the probability of HMI with 0.11 failure rate for an 8 m Alert Limit in an urban scenario.

description: We report imaging polarimetry of segments B and C of the Jupiter-family Comet 73P/Schwassmann-Wachmann 3 in the I and H bandpasses at solar phase angles of approximately 35 and 85deg. The level of polarization was typical for active comets, but larger than expected for a Jupiter-family comet. The polarimetric color was slightly red (dP/dL = +1.2 +/- 0.4) at a phase angle of ~ 35deg and either neutral or slightly blue at a phase angle of ~ 85deg. Observations during the closest approach from 2006 May 11-13 achieved a resolution of 35 km at the nucleus. Both segments clearly depart from a 1/rho surface brightness for the first 50 - 200 km from the nucleus. Simulations of radiation driven dust dynamics can reproduce some of the observed coma morphology, but only with a wide distribution of initial dust velocities (at least a factor of 10) for a given grain radius. Grain aggregate breakup and fragmentation are able to reproduce the observed profile perpendicular to the Sun-Comet axis, but fit the observations less well along this axis (into the tail). The required fragmentation is significant, with a reduction in the mean grain aggregate size by about a factor of 10. A combination of the two processes could possibly explain the surface brightness profile of the comet.

description: We develop a nanoscale dynamical mean-field theory (nano-DMFT) to deal with strong Coulomb interaction effects in physical systems that are intermediate in size between atoms and bulk materials, taking into account the tunneling into nearby electrodes. Focusing on a simplified treelike geometry, the usual DMFT loop simply stops when the finite lattice is fully covered, starting with an initial seed provided by the electronic environment at the boundary. To illustrate this nano-DMFT, we investigate the disappearance of the quasiparticle weight in a correlated nano object near the Mott transition. In contrast to thermally driven classical phase transitions, quantum effects lead to unexpected oscillations of the order parameter, related to the interference of coherent renormalized quasiparticles. This behavior also implies a spatially inhomogeneous Mott localization process at the nanoscale.

Psychopathy and language processing: an event-related potential (ERP) investigation
Creators: name: Kiehl, Kent Anthony
Publisher: name: University of British Columbia
Year: 2009

description: Three experiments tested the hypothesis that psychopathy is associated with abnormal processing of semantic and affective verbal information. Experiments 1 and 2 investigated the ability of psychopaths to show behavioral and event-related potential (ERP) differentiation for concrete and abstract words. The relevant ERP components of the nonpsychopaths differentiated concrete and abstract words in a pattern consistent to that found with noncriminals. In contrast, psychopaths were less accurate than nonpsychopaths when categorizing abstract words and they failed to demonstrate the appropriate neural differentiation between concrete and abstract words. Experiment 3 explored the ability of psychopaths and nonpsychopaths to discriminate between words that differed in emotional polarity. Both groups responded faster to positive than to negative words. However, in nonpsychopaths the early (P200) and late components (P300 and Late Positive Complex) of the ERP were larger for the negative words than positive words. Psychopaths failed to show any ERP differentiation between positive and negative words. Additionally, in all three experiments, the ERPs of the psychopaths were characterized by a large centro-frontal negative-going wave in the 300 - 500 ms time window (N350). The functional significance of this large negative wave and related findings for understanding psychopathy are discussed.

description: We provide evidence that high-pressure high-temperature (2.5 GPa and 1040 K) treatment of mixtures of iron with fullerene powders leads to the complete transformation of iron into iron carbide Fe$_3$C. The comparison of the magnetic properties (Curie temperature and magnetic moment) of the here studied samples and those for the ferromagnetic polymer Rh-C$_{60}$ indicates that the main ferromagnetic signal reported in those samples is due to Fe$_3$C and not related to the ferromagnetism of carbon as originally interpreted. Taking into account the results obtained in this study the original paper on ``Magnetic carbon" (Nature {\bf 413}, 716 (2001)) was recently retracted.

We performed 3D spectroscopic observations of these galaxies using the MPFS spectrograph at the Russian 6-m telescope, and obtained spatially resolved distributions of kinematical and stellar population parameters by fitting high-resolution PEGASE.HR synthetic single stellar populations (SSP) in the pixel space. In all three galaxies, the luminosity weighted age of the nuclei, about 4 Gyr, is considerably younger than population in the outer regions of the galaxies. We discuss two possibilities to acquire the observed structures -- dissipative merger event and different ram pressure stripping efficiency during two consequent crossings of the Virgo cluster centre.

description: We report on magnetotransport measurements in a high-mobility two-dimentional electron system subject simultaneously to AC (microwave) and DC (Hall) fields. We find that DC excitation affects microwave photoresistance in a nontrivial way. Photoresistance maxima (minima) evolve into minima (maxima) and back, reflecting strong coupling and interplay of AC- and DC-induced effects. Most of our observations can be explained in terms of indirect electron transitions using a new, ``combined'' resonant condition. Observed quenching of microwave-induced zero resistance by a DC field cannot be unambiguously linked to a domain model, at least until a systematic theory treating both excitation types within a single framework is developed.

We report the magnetic and spectral properties of C20 as a function of U/t and investigate electronic pair binding. Solid forms of C20 are studied using cluster perturbation theory and evidence is found for a metal-insulator transition at U ~ 4t. We also investigate the relevance of strong correlations to the Jahn-Teller effect in C20.

description: Elastic valley metamaterials offer an excellent platform to manipulate elastic waves and have potential applications in energy harvesting and elastography. Here we introduce a series of strategies to realize topological transition in spiral elastic valley metamaterials by parameter modulations. We show the evolution of Berry curvature and valley Chern number as a function of inherent parameters of spiral, which further results in a general scheme to achieve topological valley edge states. Our strategy leverages multiple degrees of freedom in spiral elastic valley metamaterials to provide enhanced opportunities for desired topological states.

description: We discuss a special class of Beltrami coefficients whose associated quasiconformal mapping is bilipschitz. These are of the form the characteristic function of a planar bounded domain with smooth boundary of class C 1+epsilon times a density of class Lip epsilon on the domain. The crucial fact in the argument is the special extracancellation property of even Calderon-Zygmund kernels, namely that they have zero integral on half the unit ball. This property is expressed in a particularly suggestive way and is shown to have far-reaching consequences. The main result may also be viewed as a Lipschitz regularity result for the Beltrami equation, and so for certain planar second order elliptic equations in divergence form.

description: We describe a novel approach for the rational design and synthesis of self-assembled periodic nanostructures using martensitic phase transformations. We demonstrate this approach in a thin film of perovskite SrSnO3 with reconfigurable periodic nanostructures consisting of regularly spaced regions of sharply contrasted dielectric properties. The films can be designed to have different periodicities and relative phase fractions via chemical doping or strain engineering. The dielectric contrast within a single film can be tuned using temperature and laser wavelength, effectively creating a variable photonic crystal. Our results show the realistic possibility of designing large-area self-assembled periodic structures using martensitic phase transformations with the potential of implementing "built-to-order" nanostructures for tailored optoelectronic functionalities.

description: We compute the planar finite size corrections to the spectrum of the dilatation operator acting on two-impurity states of a certain limit of conformal $\mathcal{N}=2$ quiver gauge field theory which is a $Z_M$-orbifold of $\mathcal{N}=4$ supersymmetric Yang-Mills theory. We match the result to the string dual, IIB superstrings propagating on a pp-wave background with a periodically identified null coordinate. Up to two loops, we show that the computation of operator dimensions, using an effective Hamiltonian technique derived from renormalized perturbation theory and a twisted Bethe ansatz which is a simple generalization of the Beisert-Dippel-Staudacher~\cite{Beisert:2004hm} long range spin chain, agree with each other and also agree with a computation of the analogous quantity in the string theory. We compute the spectrum at three loop order using the twisted Bethe ansatz and find a disagreement with the string spectrum very similar to the known one in the near BMN limit of $\mathcal{N}=4$ super-Yang-Mills theory. We show that, like in $\mathcal{N}=4$, this disagreement can be resolved by adding a conjectured ``dressing factor'' to the twisted Bethe ansatz. Our results are consistent with integrability of the $\mathcal{N}=2$ theory within the same framework as that of $\mathcal{N}=4$.

description: We review the theory of continuous-variable entanglement with special emphasis on foundational aspects, conceptual structures, and mathematical methods. Much attention is devoted to the discussion of separability criteria and entanglement properties of Gaussian states, for their great practical relevance in applications to quantum optics and quantum information, as well as for the very clean framework that they allow for the study of the structure of nonlocal correlations. We give a self-contained introduction to phase-space and symplectic methods in the study of Gaussian states of infinite-dimensional bosonic systems. We review the most important results on the separability and distillability of Gaussian states and discuss the main properties of bipartite entanglement. These include the extremal entanglement, minimal and maximal, of two-mode mixed Gaussian states, the ordering of two-mode Gaussian states according to different measures of entanglement, the unitary (reversible) localization, and the scaling of bipartite entanglement in multimode Gaussian states. We then discuss recent advances in the understanding of entanglement sharing in multimode Gaussian states, including the proof of the monogamy inequality of distributed entanglement for all Gaussian states, and its consequences for the characterization of multipartite entanglement. We finally review recent advances and discuss possible perspectives on the qualification and quantification of entanglement in non Gaussian states, a field of research that is to a large extent yet to be explored.

Making the connection: a sustainable community network for British Columbia
Creators: name: Fulton, Andrew
Publisher: name: University of British Columbia
Year: 2009

description: The goals of this thesis are to identify the objectives for creating a Sustainable Community Network (SCN) within B.C., to acknowledge the various tools available to facilitate the network, and to develop illustrative models to guide those contemplating the establishment of a network. Three primary research methods were utilized in this project: literature reviews, group discussion in a focus workshop, and individual interviews. The literature reviewed focused on the fields of collaboration, networks in both technical and social capacities, and coalitions. Four objectives are identified as motives to create a SCN: to provide exchange mechanisms, to organise the "unformalized" field, to create a community of interest, and to be a vehicle for power, influence and empowerment. The emphasis at the beginning should be on building personal relationships over creating an electronic network. Other specific products and services are identified as beneficial for the stakeholders: newsletters, conferences, inventories, facilitation, and a clearinghouse for information. Alternatives for administering the network include a network manager, an administrative body, a governing body, and an intermediary broker. This research helps define networks within the field of planning. They may act as a support system, streamline efforts through collaboration or by reducing duplication of effort, act as a forum for monitoring and assessment activities, and be a source for on-going public participation. Three conceptual models are developed representing a range of possibilities for creating the network. The models are labeled the "Fundamental Network" at the basic level, the "Coalition Network", and the "Collaborative Network" at the most complex level. The need for a SCN is reconfirmed. The network should proceed from a "human scale" and develop the capabilities of the electronic network as computer literacy and technological capacity become generally available. Finally, it is recommended that the network should proceed slowly, building on community objectives and incorporating the diverse activities possible through collaboration as experience is gained. Further research is needed to clarify the potential for networks in planning and management, to better understand the evolving place for computer technology, and to monitor the effectiveness of the networks as they are implemented.

description: Włodzimierz Nowak, polnischer Journalist und Publizist, beschreibt in seinem Buch die Nüchternheit der Dinge im polnischen Alltagsleben. Ursprünglich veröffentlicht in Form von einzelnen Reportagen in der Tageszeitung Gazeta Wyborcza sowie in dazugehörigen Beilagen und Magazinen, findet sich in diesem Buch eine gewaltige Dichte an Anekdoten aus der Alltagsgeschichte in Polen. Die 19 Beiträge bestechen durch ihre individuelle Qualität sowie ihre sprachlichen Aussagekraft und verdeutlichen, gespickt mit einer Fülle an Informationen, die detailreiche Recherchearbeit Nowaks. Die Artikel widmen sich dabei Themen, die in der polnischen Gesellschaft eine starke Präsenz haben. Auseinandersetzungen mit Schwerpunkten wie Inklusion, Frauenbilder, berufliche Perspektiven, Polen in der Europäischen Union oder auch Kriminalität werden in Nowaks Buch beispielhaft erörtert. Der Autor vermeidet es dabei – bewusst oder unbewusst – die (bekannten) Geschichten aus den großen polnischen Metropolen zu beleuchten und versucht stattdessen, in seinen Beiträgen die Bevölkerung aus den polnischen Kleinstädten und alle diejenigen sprechen zu lassen, die sonst kaum gehört werden.

description: Using the finite element method we quantitatively analyse temperature field evolution in a viscoelastic solid undergoing a loading--unloading process. In particular we investigate the temperature field inside a Kelvin--Voigt type viscoelastic body with a thin cutout. We find that the viscosity significantly contributes to the temperature field changes, and that the temperature field changes initiated by the loading--unloading process are strongly concentrated at the tip of the thin cutout. The predicted temperature field qualitatively corresponds to the temperature field observed in experiments focused on simultaneous heat and strain measurements at the crack tip inside materials such as the filled rubber.

description: Yoav Peled's book brings again into international academia an almost forgotten concept of ethnic democracy. After a theoretical introduction reviewing the concept, Peled examines if ethnic democracy could be found in three cases: Northern Ireland (co-authored by Natalie Kosoi), interwar Poland, and Israel. He uses the case studies also "to offer a critical reexamination of the conditions for the consolidation and stability of ethnic democracy" (p. 1).

description: It has been proposed that cosmic acceleration or inflation can be driven by replacing the Einstein-Hilbert action of general relativity with a function f(R) of the Ricci scalar R. Such f(R) gravity theories have been shown to be equivalent to scalar-tensor theories of gravity that are incompatible with Solar System tests of general relativity, as long as the scalar field propagates over Solar System scales. Specifically, the PPN parameter in the equivalent scalar-tensor theory is gamma=1/2, which is far outside the range allowed by observations. In response to a flurry of papers that questioned the equivalence of f(R) theory to scalar-tensor theories, it was recently shown explicitly, without resorting to the scalar-tensor equivalence, that the vacuum field equations for 1/R gravity around a spherically symmetric mass also yield gamma= 1/2. Here we generalize this analysis to f(R) gravity and enumerate the conditions that, when satisfied by the function f(R), lead to the prediction that gamma=1/2.

Empirical relationships for heavy-ion equilibrated charges and charge-changing cross-sections in rarefied hydrogen and their application

description: Highly ionized heavy evaporation residues (ERs) resulting from heavy ion (HI) fusion-evaporation reactions are knocked out from solid targets to rarefied gas of gas-filled recoil separators. In gas, these ERs undergo charge-changing collisions on their way to a detection system. An equilibrium between the loss of charge (electron capture) and the gain of charge (electron loss) for ionized ERs allows one to use equilibrated charge state distributions in trajectory calculations for ERs moving through a magnetic field. The distance from a target to the point where the ER charge state distributions become to be the equilibrated one is essential for such calculations. This distance can be estimated in simulations based on electron capture and loss cross-sections for energetic HIs. Proper approximations of available experimental data have provided these cross-sections, which were applied to the simulation of the ionic charge evolution for ionized heavy ERs.

description: We study the photoproduction of $K^*(892)$ vector meson from both the charged and neutral reactions, $γp \to K^{*+} Λ$ and $γn \to K^{*0} Λ$. The production mechanisms that we consider include $t$-channel $K^*$, $K$, $κ$ exchanges, s-channel nucleon diagram, and $u$-channel $Λ$, $Σ$, $Σ^*$ diagrams. These could constitute important backgrounds for future investigation of ``missing'' resonances that can be searched for especially in these reactions. The $t$-channel $K$ meson exchange is found to dominate both reactions. The total and differential cross sections are presented together with some spin asymmetries.

description: We experimentally investigate a method of directly characterizing the photon number distribution of nonclassical light beams that is tolerant to losses and makes use only of standard binary detectors. This is achieved in a single measurement by calibrating the detector using some small amount of prior information about the source. We demonstrate the technique on a freely propagating heralded two-photon number state created by conditional detection of a two-mode squeezed state generated by a parametric downconverter.
