description: We have fabricated resonant terahertz metamaterials on free standing polyimide substrates. The low-loss polyimide substrates can be as thin as 5.5 micron yielding robust large-area metamaterials which are easily wrapped into cylinders with a radius of a few millimeters. Our results provide a path forward for creating multi-layer non-planar metamaterials at terahertz frequencies.

description: We present new XMM-Newton EPIC observations of the nuclei of the nearby radio galaxies 3C 305, DA 240, and 4C 73.08, and investigate the origin of their nuclear X-ray emission. The nuclei of the three sources appear to have different relative contributions of accretion- and jet-related X-ray emission, as expected based on earlier work. The X-ray spectrum of the FRII narrow-line radio galaxy (NLRG) 4C 73.08 is modeled with the sum of a heavily absorbed power law that we interpret to be associated with a luminous accretion disk and circumnuclear obscuring structure, and an unabsorbed power law that originates in an unresolved jet. This behavior is consistent with other narrow-line radio galaxies. The X-ray emission of the low-excitation FRII radio galaxy DA 240 is best modeled as an unabsorbed power law that we associate with a parsec-scale jet, similar to other low-excitation sources that we have studied previously. However, the X-ray nucleus of the narrow-line radio galaxy 3C 305 shows no evidence for the heavily absorbed X-ray emission that has been found in other NLRGs. It is possible that the nuclear optical spectrum in 3C 305 is intrinsically weak-lined, with the strong emission arising from extended regions that indicate the presence of jet--environment interactions. Our observations of 3C 305 suggest that this source is more closely related to other weak-lined radio galaxies. This ambiguity could extend to other sources currently classified as NLRGs. We also present XMM-Newton and VLA observations of the hotspot of DA 240, arguing that this is another detection of X-ray synchrotron emission from a low-luminosity hotspot.

description: We investigate the way in which oscillating dumb-bells, a simple microscopic model of apolar swimmers, move at low Reynold's number. In accordance with Purcell's Scallop Theorem a single dumb-bell cannot swim because its stroke is reciprocal in time. However the motion of two or more dumb-bells, with mutual phase differences, is not time reversal invariant, and hence swimming is possible. We use analytical and numerical solutions of the Stokes equations to calculate the hydrodynamic interaction between two dumb-bell swimmers and to discuss their relative motion. The cooperative effect of interactions between swimmers is explored by considering first regular, and then random arrays of dumb-bells. We find that a square array acts as a micropump. The long time behaviour of suspensions of dumb-bells is investigated and compared to that of model polar swimmers.

description: Part of a collection of letters from award-winning British poet and scholar Kathleen Raine to Percy Jarrett, owner of the dealership Philobiblion which specialized in literary books and manuscripts. Most of the letters discuss the negotiation of sales of Raine’s manuscript material (of which Irvine Library at the University of California was the primary buyer), the periodical Temenos, that Raine co-founded; and Jarret’s son-in law Robin Skelton, who was a poet and Professor of English Literature at the University of Victoria. In this letter Raine discusses the sale of some of her material to Irvine, and confesses how much she was dreading giving lectures in Victoria and her relief at no longer undertaking the trip.

description: We study localized modes on a single Ablowitz-Ladik impurity embedded in the bulk or at the surface of a one-dimensional linear lattice. Exact expressions are obtained for the bound state profile and energy. Dynamical excitation of the localized mode reveals exponentially-high amplitude oscillations of the spatial profile at the impurity location. The presence of a surface increases the minimum nonlinearity to effect a dynamical selftrapping.

Convex X-ray Spectra of PKS 2155-304 and Constraints on the Minimum Electron Energy

description: The convex (concave upward) high-energy X-ray spectra of the blazar PKS\,2155-304, observed by \emph{XMM-Newton}, is interpreted as the signature of sub-dominant inverse Compton emission. The spectra can be well fitted by a superposition of two power-law contributions which imitate the emission due to synchrotron and inverse Compton processes. The methodology adopted enables us to constrain the photon energy down to a level where inverse Compton emission begins to contribute. We show that this information supplemented with knowledge of the jet Doppler factor and magnetic field strength can be used to constrain the low-energy cutoff $γ_{\rm min}m_{\rm e} c^2$ of the radiating electron distribution and the kinetic power $P_{\rm j}$ of the jet. We deduce these quantities through a statistical fitting of the broadband spectral energy distribution of PKS\,2155-304 assuming synchrotron and synchrotron self Compton emission mechanisms. Our results favour a minimum Lorentz factor for the non-thermal electron distribution of $γ_{\rm min} \gtrsim 60$, with a preference for a value around $γ_{\rm min} \simeq 330$. The required kinetic jet power is of the order of $P_{\rm j} \sim 3\times 10^{45}$ erg s$^{-1}$ in case of a heavy, electron-proton dominated jet, and could be up to an order of magnitude less in case of a light, electron-positron dominated jet. When put in context, our best fit parameters support the X-ray emitting part of blazar jets to be dominated by an electron-proton rather than an electron-positron composition.

Coulomb excitation at intermediate energies

Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Straight line trajectories are commonly used in semi-classical calculations of the first-order Coulomb excitation cross section at intermediate energies, and simple corrections are often made for the distortion of the trajectories that is caused by the Coulomb field. These approximations are tested by comparing to numerical calculations that use exact Coulomb trajectories. In this paper a model is devised for including relativistic effects in the calculations. It converges at high energies towards the relativistic straight-line trajectory approximation and approaches the non-relativistic Coulomb trajectory calculation at low energies. The model is tested against a number of measurements and analyses that have been performed at beam energies between 30 and 70 MeV/nucleon, primarily of quadrupole excitations. Remarkably good agreement is achieved with the previous analyses, and good agreement is also achieved in the few cases, where the B(E$λ$) value is known from other methods. The magnitudes of the relativistic and Coulomb distortion effects are discussed.

description: Fractional optimal control problems via a wide class of fractional operators with a general analytic kernel are introduced. Necessary optimality conditions of Pontryagin type for the considered problem are obtained after proving a Gronwall type inequality as well as results on continuity and differentiability of perturbed trajectories. Moreover, a Mangasarian type sufficient global optimality condition for the general analytic kernel fractional optimal control problem is proved. An illustrative example is discussed.

description: We present a study of the evolved stellar populations in the dwarf spheroidal galaxy LeoII, based on JHKs observations obtained with the near-infrared array WFCAM at the UKIRT telescope. Combining the new data with optical data, we derived photometric estimates of the distribution of global metallicity [M/H] of individual red giant stars from their V-Ks colours. We used the new data to derive the properties of a nearly complete sample of asymptotic giant branch (AGB) stars in LeoII. Using a near-infrared two-colour diagram, we were able to obtain a clean separation from Milky Way foreground stars and discriminate between carbon- and oxygen-rich AGB stars. We simulate the JHKs data with the TRILEGAL population synthesis code together with the most updated thermally pulsing AGB models, and using the star formation histories derived from independent work based on deep HST photometry. After scaling the mass of LeoII models to the observed number of upper RGB stars, we find that present models predict too many O-rich TP-AGB stars of higher luminosity due to a likely under-estimation of either their mass-loss rates at low metallicity, and/or their degree of obscuration by circumstellar dust. On the other hand, the TP-AGB models are able to reproduce the observed number and luminosities of carbon stars satisfactorily well, indicating that in this galaxy the least massive stars that became carbon stars should have masses as low as ~1 M_sun.

description: Deliverable 9.2: Consumer feedback report covers domestic households and Micro Small and Medium Enterprises in the food sector who rely on firewood and charcoal to meet their cooking and heating needs.A systematic market research was carried out to evaluate the suitability of Steambio Africa solid biofuel as an alternative fuel for household and business uses. The acceptance and use of the biofuel is affected by factors including its packaging, size and performance compared to other existing fuels such as firewood and charcoal. The project reports on feedback from trial users on the uses and perceptions of the solid biofuel features that can affect its acceptability and use.Domestic user trials were conducted with a sample of 35 participants in Botswana and 28 participants in Namibia. Participants were from households and Micro Small and Medium Enterprises (MSME). Feedback from respondents was generated through interviews focusing on biofuel uses, perceptions on features that affect its acceptability and suggestions by trial users. A semi-structured questionnaire was used to carry out interviews in both countries.Overall, the results of the project indicate that for the biofuel to be acceptable for both home and business use, it must be able to compete with other existing fuels such as firewood and charcoal. It is expected that this feedback will enable adjustments to the processing of the solid biofuel wood chips to meet consumer preferences.
An account of the changes in biology education in Ontario high schools (1871-1978)
Creators: name: Taylor, Stanley James
Publisher: name: University of British Columbia
Year: 2010

description: This study traces biology education in Ontario High schools from 1871 to 1978, and is the first major study of the development of Ontario biology in forty years. The author examines a variety of data sources for information about the biology curricula in regard to aims, content, methods and evaluation. For convenience in organizing the data, the century studied is divided into three periods: (a) a period of education for a minority (1871-1920) (b) a period of expanding enrolment (1921-1960) and (c) a period of educational flux (1961-1978). Over the three- periods the following changes were noted: (i) The topics covered changed considerably over the hundred years starting with taxonomy and proceeding through morphology and related physiology, applications of biology, genetics, ecology and cell biology. (ii) The educational emphasis and authorship of the textbooks changed. In the first period, the authors were university biologists and stressed the structure of biology; in the second period, the authors were teachers and emphazized the topics of pupil interest; while in the third, the authors were teams of biologists and teachers and stressed both biological structure and student interest, (iii) The physical facilities changed throughout the period reflecting the curricular concept currently in vogue, (iv) Over most of the hundred years Ontario secondary teachers of biology had high academic and professional qualifications. However, there were times of teacher shortages in which qualifications declined, (v) The opportunities for the "average" high school pupil to learn biology increased greatly over the hundred years as the proportion of pupils attending high school increased eighteen-fold. Pupils enrolled in agriculture much later than in biology and the proportion of pupils studying agriculture varied with the community's need for farmers. The biology programs are related to the four curricular ideologies or concepts outlined by Michael Schiro (1978); the scholar academic ideology, the child study ideology, the social efficiency ideology and the social reconstruction ideology. The author found that the scholar academic concept was dominant throughout but declined during the second period; the social efficiency concept appeared in the first period but was declining by the third; the child study approach provided a competing ideology in the second and third periods; and the social reconstruction concept emerged during the third.

He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this postcard, Raine tells Skelton to mention her as a reference. She also mentions T. S. Eliot.
Machine learning approaches to identify thresholds in a heat-health warning system context

description: During the last two decades, a number of countries or cities established heat-health warning systems in order to alert public health authorities when some heat indicator exceeds a predetermined threshold. Different methods were considered to establish thresholds all over the world, each with its own strengths and weaknesses. The common ground is that current methods are based on exposure-response function estimates that can fail in many situations. The present paper aims at proposing several data-driven methods to establish thresholds using historical data of health issues and environmental indicators. The proposed methods are model-based regression trees (MOB), multivariate adaptive regression splines (MARS), the patient rule-induction method (PRIM) and adaptive index models (AIM). These methods focus on finding relevant splits in the association between indicators and the health outcome but do it in different fashions. A simulation study and a real-world case study hereby compare the discussed methods. Results show that proposed methods are better at predicting adverse days than current thresholds and benchmark methods. The results nonetheless suggest that PRIM is overall the more reliable method with low variability of results according to the scenario or case.
Causal Discovery in High-Dimensional Point Process Networks with Hidden Nodes

description: Thanks to technological advances leading to near-continuous time observations, emerging multivariate point process data offer new opportunities for causal discovery. However, a key obstacle in achieving this goal is that many relevant processes may not be observed in practice. Naive estimation approaches that ignore these hidden variables can generate misleading results because of the unadjusted confounding. To plug this gap, we propose a deconfounding procedure to estimate high-dimensional point process networks with only a subset of the nodes being observed. Our method allows flexible connections between the observed and unobserved processes. It also allows the number of unobserved processes to be unknown and potentially larger than the number of observed nodes. Theoretical analyses and numerical studies highlight the advantages of the proposed method in identifying causal interactions among the observed processes.

It is shown that stimulated emission of the plasmon-LO mode is possible in the frequency range corresponding to the Reststrahlen band of GaAs both in a 6 nm wide HgTe/CdTe QW and in a 5 nm wide HgTe/Cd0.7Hg0.3Te QW grown on the (013) plane. Due to the anisotropy of the dispersion law for the plasmon-LO mode, the [03-1] direction appears to be optimal for generation.

description: We analyse intermediate-resolution VLT FLAMES/Giraffe spectra of six ultra-compact dwarf (UCD) galaxies in the Fornax cluster. We obtained velocity dispersions and stellar population properties by full spectral fitting against PEGASE.HR models. Objects span a large range of metallicities (-0.95 to -0.23 dex), 4 of them are older than 8 Gyr. Comparison of the stellar and dynamical masses suggests that UCDs have little dark matter at best. For one object, UCD3, the Salpeter initial mass function (IMF) results in the stellar mass significantly exceeding the dynamical one, whereas for the Kroupa IMF the values coincide. Although, this object may have peculiar dynamics or/and stellar populations, the Kroupa IMF seems more realistic. We find that UCDs lie well above the metallicity-luminosity relation of early-type galaxies. The same behaviour is demonstrated by some of the massive Milky Way globular clusters, known to contain composite stellar populations. Our results support two following UCD formation scenarii: (1) tidal stripping of nucleated dwarf elliptical galaxies; (2) formation of tidal superclusters in galaxy mergers. We also discuss some of the alternative channels of the UCD formation binding them to globular clusters.

description: ALICE has been specifically optimized to study heavy-ion collisions at the LHC, up to a charged particle density of 8000 per unit of rapidity in central heavy-ion collisions at $\sqrt{s_{NN}}$ = 5.5 TeV. The High Momentum Particle Identification Detector (HMPID) has a proximity focusing geometry with a liquid $\rm C_{6}F_{14}$ Cherenkov radiator coupled to Multi-Wire Pad Chambers (MWPC) equipped with CsI photocathodes, over a total active area of 11 $\rm m^2$. It has been designed to identify charged pions and kaons in the range 1 $\leq p \leq$ 3 \GeV/$c$ and protons in the range 2 $\leq p \leq$ 5 \GeV/$c$. The as-built detector and all relevant subsystems (gas, liquid $\rm C_{6}F_{14}$, cooling and control) are described. Installation issues and first commissioning results are also presented.

description: We propose a scheme to investigate the nonequilibrium work distribution of a quantum particle under well controlled transformations of the external potential, exploiting the versatility of a single ion in a segmented linear Paul trap. We describe in detail how the motional quantum state of a single ion can be prepared, manipulated and finally read out to fully determine the free energy difference in both harmonic and anharmonic potentials. Uniquely to our system, we show how an ion may be immersed in an engineered laser--field reservoir. Trapped ions therefore represent an ideal tool for investigating the Jarzynski equality in open and closed quantum systems.

description: We study the ground states of one-dimensional Bose-Bose mixtures under harmonic confinement. As we vary the inter-species coupling strength up to the limit of infinite repulsion, we observe a generalized, composite-fermionization crossover. The initially coexisting phases demix as a whole (for weak intra-species interactions) and separate on an atomic level (for strong intra-species repulsion). By symmetry, the two components end up with strongly overlapping profiles, albeit sensitive to symmetry-breaking perturbations. Different pathways emerge in case the two components have different atom numbers, different intra-species interactions, or different masses and/or trap frequencies.

description: Electron cooling, in which free electrons lose energy to vibrational excitation of gases, has been identified as a significant process in the atmospheres of Mars and Venus for electron impact on CO2. This process does not appear to have been evaluated for CO, although the density of CO exceeds that of CO2 in the upper atmospheres of these planets. In this paper electron cooling rates for CO are calculated and compared with existing rates for CO2. It is found that electron cooling by CO becomes more significant than by CO2 above altitudes of about 300 km on Mars and about 168 km on Venus. The sensitivity of the calculated cooling rates to different measurements of the integral cross sections for electron-impact vibrational excitation of CO is also investigated.

description: Part of a collection of letters from award-winning British poet and scholar Kathleen Raine to Percy Jarrett, owner of the dealership Philobiblion which specialized in literary books and manuscripts. Most of the letters discuss the negotiation of sales of Raine’s manuscript material (of which Irvine Library at the University of California was the primary buyer), the periodical Temenos, that Raine co-founded; and Jarret’s son-in law Robin Skelton, who was a poet and Professor of English Literature at the University of Victoria. In this letter Raine gives Jarrett to throw out any of her material that has no value, and tells him she can't face coming to visit Victoria.

description: A strong background field will change the vacuum structure and the proper basis of a system drastically in both classical and quantum mechanics, e.g. the Landau levels in a background magnetic field. The situation is the same for the rotating case. In such a system the usual set of plane-wave states would no longer be suitable as a starting point of perturbation. Alternatively and straightforwardly in a rapidly and globally rotating system, it is better to reformulate the perturbation computation in principle. In this work we will complete the first step for the spin-1 field, which includes solving the Proca equation in present of a background rotation and complete its canonical quantization. It will be shown that because of the symmetry the eigen states are actually the same as the ones of Maxwell equations in cylindrical coordinate. The propagator as well as the near-central approximation will be obtained by considering the vorticity areas are so small in the relativistic QGP.

Bayesian optimisation
Gaussian processes
heteroscedasticity

description: Abstract: Bayesian optimisation is a sample-efficient search methodology that holds great promise for accelerating drug and materials discovery programs. A frequently-overlooked modelling consideration in Bayesian optimisation strategies however, is the representation of heteroscedastic aleatoric uncertainty. In many practical applications it is desirable to identify inputs with low aleatoric noise, an example of which might be a material composition which displays robust properties in response to a noisy fabrication process. In this paper, we propose a heteroscedastic Bayesian optimisation scheme capable of representing and minimising aleatoric noise across the input space. Our scheme employs a heteroscedastic Gaussian process surrogate model in conjunction with two straightforward adaptations of existing acquisition functions. First, we extend the augmented expected improvement heuristic to the heteroscedastic setting and second, we introduce the aleatoric noise-penalised expected improvement (ANPEI) heuristic. Both methodologies are capable of penalising aleatoric noise in the suggestions. In particular, the ANPEI acquisition yields improved performance relative to homoscedastic Bayesian optimisation and random sampling on toy problems as well as on two real-world scientific datasets.

description: Abstract: The plant efficiency of a nuclear fusion power plant is considered. During nominal operation, the plant efficiency is determined by the thermodynamic efficiency and the recirculated power fraction. However, on average the reactor operates below the nominal power, even when the long shutdown periods for large maintenance are left outside the averaging. Hence, next to the recirculated power fraction the capacity factor must be factored in. An expression for the plant efficiency which incorporates both factors is given. It is shown that the combination of high recirculated power fraction and a low capacity factor, results in poor plant efficiency. This is due to the fact that in a fusion reactor the recirculated power remains high if it runs at reduced output power. It is argued that, at least for a first generation of power plants, this combination is likely to occur. Worked out example calculations are given for the models of the power plant conceptual study. Finally, the impact on the competitiveness of fusion on the energy market is discussed. This analysis stresses the importance of the development of plant designs with low recirculated power fraction.
The place of vacuum forming in secondary sculpture and design programs
Creators: name: Glen, Barry Willis
Publisher: name: University of British Columbia
Year: 2010

description: The author contends that traditional methods and materials used to teach sculpture and design at the secondary level need to be supplemented with materials and processes which are a part of every student's contemporary experience. The thermal vacuum forming of plastics is an industrial process easily adapted to fulfill many of the goals and learning outcomes of art education. In the first part of the thesis, two questions are posed: "what is sculpture?" and "what is taught as sculpture in the context of art education?" The author arrives at the answer to the first question through an analysis of two divergent views of modern sculpture contained in the writings of Herbert Read (1964) and Rosalind Krauss (1977). The writings of contemporary sculptors are also considered. To answer the second question, the author engages in a historical review of the place of sculpture and design in art education since 1850, with particular reference to three influential factors: the rather pragmatic nature of society's interests which are often more utilitarian than aesthetic; the rise of the arts and crafts movement during the l880's and the on-going confusion between art, crafts, and industrial art; and the profound influence of the Bauhaus on educational thought from the 1920's to the present. Innovation in sculpture and art education are discussed in terms of a phenomenon peculiar to our technological era: the rapid acceleration of change. The impact of new materials and techniques on the evolution of modern sculpture is analyzed in relation to four significant events: Picasso's invention of assemblage, the use of "ready mades" in art, constructivism, and the application of welding to sculpture. The author considers some of the ways in which artists have exploited the unique characteristics of plastics in their sculpture; characteristics such as optical properties, casting and thermoforming capabilities, and reinforced plastic's high strength combined with light weight. The use of vacuum formed plastics in the sign industry is described and illustrated. The second half of this thesis expands upon the role of vacuum forming in the secondary art program. Goals and learning outcomes for the teaching of sculpture and design are discussed, and the creative potential of vacuum forming is assessed in the light of this discussion. Later sections describe vacuum forming in detail, including mold making, forming processes, fastening and glueing procedures, and finishing. Photographs of student work are used extensively to illustrate these sections. Finally, practical considerations and the limitations of vacuum forming are dealt with. The appendix includes notes and technical data on plastics, safety procedures, and drawings and practical suggestions for constructing a "budget" vacuum form machine.
