description: We present a search for the radiative leptonic decay B+ -> l+ nu gamma, where l=e,mu, using a data sample of 465 million B-meson pairs collected by the BABAR experiment. In this analysis, we fully reconstruct the hadronic decay of one of the B mesons in Upsilon(4S) -> B+B- decays, then search for evidence of B+ -> l+ nu gamma in the rest of the event. We observe no significant evidence of signal decays and report model-independent branching fraction upper limits of BR(B+ -> e+ nu gamma)<17e-6, BR(B+ -> mu+ nu gamma)< 24e-6, and BR(B+ -> l+ nu gamma)<15.6e-6 (l= e or mu), all at the 90% confidence level.

Liability for marine pollution by ships
Creators: name: Young, Charles A.
Publisher: name: University of British Columbia
Year: 2010

description: One aspect of the international problem of marine pollution is pollution by ships. As an international problem, pollution by ships demands action at a level above the national. Many international agreements have been reached, but this thesis argues that a comprehensive liability regime is now necessary. To find the principles upon which such a liability regime should be based, decisions of international tribunals, acts of state practice, and existing conventional arrangements are canvassed. "Reasonableness" is found to be the central characteristic, and is given more specific meaning through the survey. A convention is proposed in general outline only, but a regional framework is suggested, and principles on which to base the convention are summarized.

description: Identification of minerals in the field is a task that is wrought with many challenges. Traditional approaches are prone to errors where there is no enough experience and expertise. Several existing techniques mainly make use of features of the minerals under a microscope and tend to favour a manual feature extraction pipeline. Deep learning methods can help overcome some of these hurdles and provide simple and effective ways to identify minerals. In this paper, we present an algorithm for identifying minerals from hand specimen images. Using a Convolutional Neural Network (CNN), we develop a single-label image classification model to identify and categorise seven classes of minerals. Experiments conducted using real-world datasets show that the model achieves an accuracy of 90.75%.

description: The interface formation between Ba₀.₆Sr₀.₄TiO₃ and Al₂O₃ has been studied using photoelectron spectroscopy with in situ sample preparation. A negligible valence band discontinuity, corresponding to a ∼5.6 eV barrier for electron transport at the BST/Al₂O₃ interface is determined. Current-voltage measurements show that the leakage current can be significantly reduced by inserting the Al₂O₃ barrier layer between barium strontium titanate (BST) and Pt electrode. Different charge injection behavior depending on Al₂O₃ thickness is observed, which correspond well with the experimentally determined energy band diagrams. Direct tunneling from the metal electrode into the BST conduction band through the Al₂O₃ barrier layer is observed.

description: The European Genomic Data Infrastructure (GDI) is a deployment project, co-funded by the Digital Europe programme. GDI's main objective is to realise the data infrastructure required by the 1+MG initiative to share high-quality genotypic and phenotypic data across borders; the 1+MG Virtual Cohort. Countries participating have committed to reach a concrete operational level before the end of the project (progressing across different phases: onboarding, deployment or operational) which will require them to fulfil technical and non-technical requirements.
 In addition, the establishment of required technical capacity in each Node has been identified as a critical factor for the success of the project and the long-term sustainability of the data infrastructure and the initiative.
 This document presents the results of the initial European Genomic Data Infrastructure monitoring activities layed out in D1.12 that are initially focussed on: ● the deployment of the technical expertise required to deploy and operate the European Genomic Data Infrastructure to share access to data across borders, building the technical capacity to run the infrastructure beyond the end of the project, and,
 ● the evolution of the European Genomic Data Infrastructure Nodes. GDI Nodes will transition across different phases in their journey to be fully operational and integrated into the European Genomic Data Infrastructure.

description: The diffraction of ultrasound by a circular disk and an aperture of the same size have been investigated as a demonstration of Babinet's principle in the Fresnel regime. The amplitude and the phase of diffracted ultrasonic waves have been measured, and a graphical treatment of the results is performed by simply drawing vectors (phasors) in the complex plane. The results verify Babinet's principle. It is also found that the incident wave is indeed 90 deg behind the phase of the wave passing through on the central axis of a circular aperture. This paradox has previously been regarded as a defect of Fresnel's theory. The apparatus used is intended as a table-top instrument for the student laboratory in general science and engineering classes.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The influence of the curvature on the dynamical properties of transversal domain walls in a thin antiferromagnetic wire is studied theoretically. Equations of motion for antiferromagnetic domain wall are obtained within the collective variable approach ($q-Φ$ model). It is shown that (i) for the case of localized bend, curvature results in a pinning potential for domain wall. (ii) The gradient of the curvature results in a driving force on the domain wall and it effectively moves without any external stimuli. Although we showcase our approach on the specific parabola and Euler spiral geometries, the approach is general and valid for a wide class of geometries. All analytical predictions are confirmed by numerical simulations.

description: High conductivity in the off-state and low field-effect mobility compared to bulk properties is widely observed in the p-type thin-film transistors of Cu₂O, especially when processed at moderate temperature. This work presents results from in situ conductance measurements at thicknesses from sub-nm to around 250 nm with parallel X-ray photoelectron spectroscopy. An enhanced conductivity at low thickness is explained by the occurrence of Cu(II), which is segregated in the grain boundary and locally causes a conductivity similar to CuO, although the surface of the thick film has Cu₂O stoichiometry. Since grains grow with an increasing film thickness, the effect of an apparent oxygen excess is most pronounced in vicinity to the substrate interface. Electrical properties of Cu₂O grains are at least partially short-circuited by this effect. The study focuses on properties inherent to copper oxide, although interface effects cannot be ruled out. This non-destructive, bottom-up analysis reveals phenomena which are commonly not observable after device fabrication, but clearly dominate electrical properties of polycrystalline thin films.

Perspective of Galactic dark matter subhalo detection on Fermi from the EGRET observation

description: The perspective of the detectability of Galactic dark matter subhaloes on the Fermi satellite is investigated in this work. Under the assumptions that dark matter annihilation accounts for the "GeV excess" of the Galactic diffuse $γ$-rays discovered by EGRET and the $γ$-ray flux is dominated by the contribution from subhaloes of dark matter, we calculate the expected number of dark matter subhaloes that Fermi may detect. We show that Fermi may detect a few tens to several hundred subhaloes in 1-year all sky survey. Since EGRET observation is taken as a normalization, this prediction is independent of the particle physics property of dark matter. The uncertainties of the prediction are discussed in detail. We find that the major uncertainty comes from the mass function of subhaloes, i.e., whether the subhaloes are "point like" (high-mass rich) or "diffuse like" (low-mass rich). Other uncertainties like the background estimation and the observational errors will contribute a factor of $2\sim 3$.

description: This work studies the optical binding of a dimer composed by dielectric particles close to a graphene sheet. Using a rigorous electromagnetic method, we calculated the optical force acting on each nanoparticle. In addition, we deduced analytical expressions enabling to evaluate the contribution of graphene surface plasmons (GSPs) to optical binding. Our results show that surface plasmon on graphene excitations generate multiple equilibrium positions for which the distance between particles are tens of times smaller than the photon wavelength. Moreover, these positions can be dynamically controlled by adjusting the chemical potential on graphene. Normal and oblique incidence have been considered.

description: The impact of large-scale constellations of satellites, is a concern for ground-based astronomers. In recent years there has been a significant increase in the number of satellites in Low-Earth Orbit and this trend is set to continue. The large number of satellites increases the probability that one will enter the field of view of a ground-based telescope at the right solar angle to appear bright enough that it can corrupt delicate measurements. We present a new tool Astrosat that will project satellite orbits onto the RA/DEC coordinate system for a given observer location and time and field of view. This enables observers to mitigate the effects of satellite trails through their images by either avoiding the intersection, post-processing using the information as a prior or shuttering the observation for the duration of the transit. We also provide some analysis on the apparent brightness of the largest of the constellations, Starlink, as seen by a typical observatory and as seen with the naked eye. We show that a naked eye observer can typically expect to see a maximum of 5 Starlink satellites at astronomical twilight, when the sky is dark. With the intended 40000 satellites in the constellation, that number would increase to 30.

description: We present new results of the HESS J1731-347/SNR G353.6-0.7 system from XMM-NEWTOM and Suzaku X-ray observations, and Delinha CO observations. We discover extended hard X-rays coincident with the bright, extended TeV source HESS J1731-347 and the shell of the radio SNR. We find that spatially-resolved X-ray spectra can generally be characterized by an absorbed power-law model, with photon-index of ~ 2, typical of non-thermal emission. A bright X-ray compact source, XMMS J173203-344518, is also detected near the center of the SNR. We find no evidence of a radio counterpart or an extended X-ray morphology for this source, making it unlikely to be a pulsar wind nebular (PWN). The spectrum of the source can be well fitted by an absorbed blackbody with a temperature of ~ 0.5 keV plus a power-law tail with a photon-index of ~ 5, reminiscent of the X-ray emission of a magnetar. CO observations toward the inner part of the HESS source reveal a bright cloud component at -20+/-4 km s^{-1}, which is likely located at the same distance of ~ 3.2 kpc as the SNR. Based on the probable association between the X-ray and $γ$-ray emissions and likely association between the CO cloud and the SNR, we argue that the extended TeV emission originates from the interaction between the SNR shock and the adjacent CO clouds rather than from a PWN.

description: A near-infrared imaging study of the evolved stellar populations in the dwarf spheroidal galaxy Leo I is presented. Based on JHK observations obtained with the WFCAM wide-field array at the UKIRT telescope, we build a near-infrared photometric catalogue of red giant branch (RGB) and asymptotic giant branch (AGB) stars in Leo I over a 13.5 arcmin square area. The V-K colours of RGB stars, obtained by combining the new data with existing optical observations, allow us to derive a distribution of global metallicity [M/H] with average [M/H] = -1.51 (uncorrected) or [M/H] = -1.24 +/- 0.05 (int) +/- 0.15 (syst) after correction for the mean age of Leo I stars. This is consistent with the results from spectroscopy once stellar ages are taken into account. Using a near-infrared two-colour diagram, we discriminate between carbon- and oxygen-rich AGB stars and obtain a clean separation from Milky Way foreground stars. We reveal a concentration of C-type AGB stars relative to the red giant stars in the inner region of the galaxy, which implies a radial gradient in the intermediate-age (1-3 Gyr) stellar populations. The numbers and luminosities of the observed carbon- and oxygen-rich AGB stars are compared with those predicted by evolutionary models including the thermally-pulsing AGB phase, to provide new constraints to the models for low-metallicity stars. We find an excess in the predicted number of C stars fainter than the RGB tip, associated to a paucity of brighter ones. The number of O-rich AGB stars is roughly consistent with the models, yet their predicted luminosity function is extended to brighter luminosity. It appears likely that the adopted evolutionary models overestimate the C star lifetime and underestimate their K-band luminosity.

description: Recently, rapid quality assessment of food is an increasingly important topic. The rising demand of consumers for high quality products generates a need to establish fast and suitable analytical methods. Near-infrared (NIR) spectroscopy has turned out to be a time-saving, cheap, easy-to-use and environmentally friendly technique, which can be applied for the determination of manifold quality attributes in various kinds of food matrices. This article gives overview of the basic principles of near-infrared measurements and describes the immense field of applications, with the main focus on fruits, grapes and wine and the evaluation of wine aroma.

description: Hyperbolicity is a graph parameter related to how much a graph resembles a tree with respect to distances. Its computation is challenging as the main approaches consist in scanning all quadruples of the graph or using fast matrix multiplication as building block, both are not practical for large graphs. In this paper, we propose and evaluate an approach that uses a hierarchy of distance-k dominating sets to reduce the search space. This technique, compared to the previous best practical algorithms, enables us to compute the hyperbolicity of graphs with unprecedented size (up to a million nodes) and speeds up the computation of previously attainable graphs by up to 3 orders of magnitude while reducing the memory consumption by up to more than a factor of 23.

description: Quantum Brownian motion, described by the Caldeira-Leggett model, brings insights to understand phenomena and essence of quantum thermodynamics, especially the quantum work and heat associated with their classical counterparts. By employing the phase-space formulation approach, we study the heat distribution of a relaxation process in the quantum Brownian motion model. The analytical result of the characteristic function of heat is obtained at any relaxation time with an arbitrary friction coefficient. By taking the classical limit, such a result approaches the heat distribution of the classical Brownian motion described by the Langevin equation, indicating the quantum-classical correspondence principle for heat distribution. We also demonstrate that the fluctuating heat at any relaxation time satisfies the exchange fluctuation theorem of heat, and its long-time limit reflects complete thermalization of the system. Our research brings justification for the definition of the quantum fluctuating heat via two-point measurements.

description: We propose a consistent setup for the holographic dual of the strongly coupled large-Nc N=4 super Yang-Mills theory plasma which undergoes the Bjorken flow relevant to the quark-gluon plasma at BNL Relativistic Heavy Ion Collider and CERN LHC. The dual geometry is constructed order by order in a well-defined late-time expansion. The transport coefficients are determined by the regularity of the geometry. We prove, for the first time, that the dual geometry has an apparent horizon hence an event horizon, which covers a singularity at the origin. Further we prove that the dual geometry is regular to all orders in the late-time expansion under an appropriate choice of the transport coefficients. This choice is also shown to be unique. Our model serves as a concrete well-defined example of a time-dependent AdS/CFT dual.

description: We report the comparison between unresolved reflectance spectroscopy of Solar System small bodies and laboratory measurements on reference surfaces. We measure the bidirectional reflectance spectroscopy of a powder of howardite and a sublimation residue composed of a Ceres analogue. The spectra are then inverted using the Hapke semi-empirical physical model and the MRTLS parametric model to be able to simulate the reflectance of the surfaces under any geometrical configuration needed. We note that both models enable an accurate rendering of the reflectance spectroscopy, but the MRTLS model adds less noise on the spectra compared to the Hapke model. Using the parameters resulting from the inversions, we simulate two spherical bodies and the small bodies (1)Ceres and (4)Vesta whose surfaces are homogeneously covered with the Ceres analogue and powder of howardite respectively. We simulate various scenarios of illumination and spectroscopic observations, spot-pointing and fly-bys, of these small bodies for phases angles between 6° and 135°. The unresolved reflectance spectroscopy of the simulated bodies is retrieved from the resulting images, and compared to the reflectance spectroscopy of the reference surface. Our results show that the photometric phase curves of the simulated bodies are different from the reference surfaces because of the variations of the local incidence and emergence angles due to the shape and topography of the surface. We observe the maximum differences at wide phase angles with the various simulated observations of (4)Vesta due to its high surface topography. Finally, we highlight the differences in the spectral parameters derived from the unresolved observations at 30° with laboratory measurements acquired under a single geometrical configuration.

description: We use the Thom-Whitney construction to show that infinitesimal deformations of a coherent sheaf F are controlled by the differential graded Lie algebra of global sections of an acyclic resolution of the sheaf End(E), where E is any locally free resolution of F. In particular, one recovers the well known fact that the tangent space to deformations of F is Ext^1(F,F), and obstructions are contained in Ext^2(F,F). The main tool is the identification of the deformation functor associated with the Thom-Whitney DGLA of a semicosimplicial DGLA whose cohomology is concentrated in nonnegative degrees with a noncommutative Cech cohomology-type functor.

Anticipatory Postural Control in Individuals with Stroke: Role of Asymmetries and Focused Training
Creators: name: Curuk, Etem

description: Asymmetry is one the most common consequences of a cerebrovascular accident (CVA) that causes the impaired postural control in individuals with stroke. Although postural control has been studied in people with stroke, information about their ability to generate anticipatory postural adjustments (APAs) for postural control is incomplete. Moreover, there is limited evidence available on whether anticipatory postural adjustments in individuals with unilateral stroke could be improved with training. Therefore, the focus of this dissertation was on the investigation of anticipatory postural adjustments and the role of APA-focused training in enhancement of postural control in people with stroke. First, we demonstrated that individuals with stroke, as compared to healthy counterparts, have impaired ability to generate APAs on the affected side which is compensated by increased early activation of muscles on the contralateral side. Second, we investigated whether APAs could be improved in people with stroke with exercises. We demonstrated that after a single session of targeted exercises involving their unaffected upper extremity individuals with stroke generated early APAs onsets in trunk and leg muscles on the affected side. Finally, we investigated a feasibility of multi-session training involving targeted exercises performed with the unaffected upper extremity in enhancement of postural control of individuals with stroke. The results of the study revealed that after two weeks of perturbation-based training individuals with stroke improved APAs in the muscles on both sides of the body. The outcome of the dissertation provides an evidence that individuals with stroke have impaired ability to generate anticipatory postural adjustments, however, they could enhance APAs with specialized training. This dissertation also provides a background for future investigations focusing on the role of perturbation-based training in enhancement of postural control in individuals with unilateral impairment.

description: We present updated measurements of the branching fractions for B0 meson decays to etaK0, etaeta, etaphi, etaomega, eta'K0, eta'eta', eta'phi, and eta'omega, and branching fractions and CP-violating charge asymmetries for B+ decays to etapi+, etaK+, eta'pi+ and eta'K+. The data represent the full dataset of 467 10^{6} BB pairs collected with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at the SLAC National Accelerator Laboratory. Besides large signals for the four charged B decay modes and for B0\to eta'K0, we find evidence for three B0 decay modes at greater than 3.0sigma significance. We find B(B0\to etaK0) = (1.15^{+0.43}_{-0.38} \pm0.09)x10^{-6}, B(B0\to etaomega) = (0.94^{+0.35}_{-0.30}\pm0.09)x10^{-6}, and B(B0\to eta'omega) = (1.01^{+0.46}_{-0.38}\pm0.09)x10^{-6}, where the first (second) uncertainty is statistical (systematic). For the B+\to etaK+ decay mode, we measure the charge asymmetry A_{ch}(B+\to etaK+) = -0.36 \pm 0.11 \pm 0.03.

description: We present a study of an extended Lyman-alpha (Lya) nebula located in a known overdensity at z~2.38. The data include multiwavelength photometry covering the rest-frame spectral range from 0.1 to 250um, and deep optical spectra of the sources associated with the extended emission. Two galaxies are associated with the Lya nebula. One of them is a dust enshrouded AGN, while the other is a powerful starburst, forming stars at >~600 Msol/yr. We detect the HeII emission line at 1640A in the spectrum of the obscured AGN, but detect no emission from other highly ionized metals (CIV or NV) as is expected from an AGN. One scenario that simultaneously reproduces the width of the detected emission lines, the lack of CIV emission, and the geometry of the emitting gas, is that the HeII and the Lya emission are the result of cooling gas that is being accreted on the dark matter halo of the two galaxies, Ly1 and Ly2. Given the complexity of the environment associated with our Lya nebula it is possible that various mechanisms of excitation are at work simultaneously.

Disparities in Healthcare Expenditure and Mortality by Neighborhood Income in Chronic Myeloid Leukemia

description: INTRODUCTION: Tyrosine-kinase inhibitors (TKIs) for treatment of chronic myeloid leukemia (CML) is financially burdensome. Patients with a low neighborhood income, whose treatment cost is high relative to or exceeds income, may become “priced out” of treatment resulting in decreased TKI initiation and an increased rate of death. Low neighborhood income patients may also forgo non-cancer treatment to maintain cancer treatment. We evaluated the trend in TKI drug price and out-of-pocket (OOP) expenditure across time, and whether there is a disparity in mortality and non-cancer healthcare expenditure between patients with high and low neighborhood income. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) – Medicare database to conduct our analyses. We calculated annual average TKI gross-payment and monthly OOP expenditure and compared annual changes to inflation indices. Low neighborhood income was defined as a census-tract income below the median. We measured the adjusted effect of neighborhood income on the rate of TKI initiation using a Cox-proportional hazards model. Similarly, among TKI initiators, we measured the effect of neighborhood income on the rate of mortality. We used inverse probability weighted partitioned regression to measure the adjusted association between neighborhood income and cumulative non-cancer expenditure over 60-months. RESULTS: Average annual gross payment per 30-day supply of a TKI increased by an average of 12.8% annually throughout the observation, which exceeded 2% medical inflation. There was no trend in median annual OOP expenditure per 30-day supply, which varied between $450 to $600. We found that of 503 CML cases, low neighborhood income was not associated with TKI initiation (HR=1.12, P=0.48). Among 354 TKI initiators, low neighborhood income was associated with an increased rate of CML-specific death (HR=3.24, P=0.04), and patients with low neighborhood income had an insignificant cumulative total non-cancer expenditure that was $99,110 (95% CI [-$659,485 to $275,113]) less. CONCLUSION: Escalating TKI price and high OOP expenditure places financial pressure on patients, which may manifest as an increased risk of CML-specific death in low-income patients, but not as forgoing non-cancer treatment. Patients may instead be forgoing unmeasured goods and services. Our findings support the need for policy interventions which mitigate the financial burden of cancer.

description: Shear-induced vertical mixing in a stratified flow is a key ingredient of thermohaline circulation. We experimentally determine the vertical flux of momentum and density of a forced gravity current using high-resolution velocity and density measurements. A constant eddy viscosity model provides a poor description of the physics of mixing, but a Prandtl mixing length model relating momentum and density fluxes to mean velocity and density gradients works well. For $ \approx 0.08$ and $Re_λ\approx 100$, the mixing lengths are fairly constant, about the same magnitude, comparable to the turbulent shear length.

Environment management of coastal forests in British Columbia : an ecolegal analysis
Creators: name: Mackenzie, James M.
Publisher: name: University of British Columbia
Year: 2010

description: Increasing demands for the natural resources of British Columbia coastal forests have led to conflicts between resource users. In addition recent demand for intangible "non-economic" resources, such as outdoor recreation is creating added pressure upon the wildland resource base. The British Columbia Forest Service, although restricted to some extent by a narrowly-worded "wood production" statute, has attempted to resolve forest resource conflicts by administrative action such as the development of new contract provisions and logging guidelines. These alternatives can be effectively enforced against Crown licensees due to Crown control of most timber resources, but they are largely ineffective for the regulation of private timberland operations. Although private lands are not extensive, their harvest is substantial and they comprise a significant acreage in the rich coastal forest areas. The common law offers several potential causes of action which might be employed by the Forest Service to regulate logging operations on private timberlands, particularly with respect to impact upon fishery resources in coastal forest streams. The Forest Act could also be interpreted to authorize regulation of private logging operations. Litigation, whether civil or criminal, however, is not an optimum method of environmental management. It is expensive, time-consuming, extremely technical and remedies are generally post facto in character.
