The evolution of the native land mammals of the Queen Charlotte Islands and the problem of insularity
Creators: name: Foster, J. Bristol
Publisher: name: University of British Columbia
Year: 2012

description: The Queen Charlotte Islands are the most isolated islands in British Columbia and are populated by eight species of indigenous land mammals, all except one of which are represented by at least one endemic form. Geological and botanical evidence lend strong support to the hypothesis that the Islands could have been a refuge to most of these mammals during the last (Vashon) glaciation. Their unique mammal fauna could be the product of insular evolution, or due to the fact that it is of geographical relicts. Absence of fossil material prohibits a final solution to this problem, but circumstantial evidence suggests that the mammals have evolved their unique characteristics as a result of living in an insular environment. This conclusion is reached after the study of the most common mammals living on the Islands; the deer mice (Peromyscus maniculatus keeni and P. sitkensis prevostensis) and the dusky shrews (Sorex obscurus elassodon and S. o. prevostensis), and after a wide literature survey of mammals found on other islands. The most important evidence favouring the insular evolution theory is the uniformity displayed when the characteristics of insular birds and mammals are compared with relatives living on the nearby mainland. Birds living on islands often possess longer tarsi and culmens; artiodactyls, lagomorphs and carnivores tend to be smaller on islands, while rodents are usually larger, live longer and possess shorter tails. A corollary of the relict hypothesis holds that a large reliot rodent can not survive active competition with the smaller form and is displaced by the latter when they come into contact. This theory could not be substantiated by the present study; on the contrary, the two would likely interbreed. The differences between the insular populations of large Peromysous are greater than one would expect if they owed their similarity to a common origin. Finally, the relict hypothesis would hold that such a characteristic as large size is conservative, whereas evidence indicates that this is not generally true. Reasons are suggested for the characteristics which are commonly found in insular mammals and herein lies the most interesting area for future work.

description: Literature research has shown that there is no proven business model canvas for platforms. Such a canvas would be a vital tool that provides added value to companies and innovators for various purposes: sharing, communication (internal and external), description, analysis, management, planning and partnering. In addition, a platform business model canvas helps follow a systematic but also pragmatic approach with regards to the transformation of a pipeline business to a platform business, the task to design a new platform or to describe an existing platform business model. The goal of this research is therefore to create a platform business model canvas that is easy to use and helps capture platform business models in a comprehensive and effective way following the Design Science Approach. The basic components/building blocks and the necessary perspectives for the platform business model canvas, are derived from literature. The need for three or more perspectives, is furtherly discussed on basis of Osterwalder’s business model canvas by outsourcing dimensions of control. Components and perspectives are subsequently verified through a qualitative analysis of the about-us-pages of 32 platform websites. The components/building blocks and perspectives are then put together to form a platform business model canvas, which is then evaluated through an illustrative case study explaining the platform business model of eBay.

Ohne ihn gäbe es nur Langeweile, also kein Spiel, oder Konflikte, also ebenfalls kein Spiel. Der Formenreichtum des Spiels in Spielgruppen speist sich aus drei elementaren Typen von Spieleinsätzen: Spielsachen, Worte und soziale Rollen. Was jeweils "auf dem Spiel steht" und mit welchem Einsatz sich die Beteiligten ins Spiel verwickeln (lassen), legt der Beitrag ausführlich dar.

Total mass distributions of Sersic galaxies from photometry $&$ cent\ ral velocity dispersion

description: We develop a novel way of finding total mass density profiles in Sersic ellipticals, to about 3 times the major axis effective radius, using no other information other than what is typically available for distant galaxies, namely the observed surface brightness distribution and the central velocity dispersion $σ_0$. The luminosity density profile of the observed galaxy is extracted by deprojecting the measured brightness distribution and scaling it by a fiduciary, step-function shaped, $raw$ mass-to-light ratio profile ($M/L$). The resulting raw, discontinuous, total, 3-D mass density profile is then smoothed according to a proposed smoothing prescription. The parameters of this raw $M/L$ are characterised by implementing the observables in a model-based study. The complete characterisation of the formalism is provided as a function of the measurements of the brightness distribution and $σ_0$. The formalism, thus specified, is demonstrated to yield the mass density profiles of a suite of test galaxies and is successfully applied to extract the gravitational mass distribution in NGC 3379 and NGC 4499, out to about 3 effective radii.

BACKGROUNDS TO THE K^0_L->π^0π^0 CHANNEL

Publisher: name: INFN Open Access Repository
Year: 1991

description: The precise measurement of ε'/ε planned at the DAPHNE ϕ-factory requires, in order not to spoil the high statistical accuracy needed, careful control of any potentially dangerous systematic error. Two possible sources, relevant to the K^0_L->π^0π^0 channel, have been studied in the present contribution, via a Montecarlo analysis focussed on the use of the time-of-flight technique for photons detected in the e. m. calorimeter:1)Due to the exponential distribution of Kl^0 decays, the number of K^0_L->π^0π^0 vertices accepted inside a radially defined fiducial volume will be a function of the shape and simmetry of the resolution obtained for the radial coordinate of the vertex.2)The main background to K^0_L->π^0π^0 events will come from KK^0_L->π^0π^0π^0 events in which 2 photons have been missed, either absorbed by the material in front of the calorimeter, or out of angular acceptance. The ultimate rejection of these events will be made using constrained kinematic fits, for which energy resolution, more than spatial resolution, will be the figure of merit.

description: We study the quantum mechanical generalization of force or pressure, and then we extend the classical thermodynamic isobaric process to quantum mechanical systems. Based on these efforts, we are able to study the quantum version of thermodynamic cycles that consist of quantum isobaric process, such as quantum Brayton cycle and quantum Diesel cycle. We also consider the implementation of quantum Brayton cycle and quantum Diesel cycle with some model systems, such as single particle in 1D box and single-mode radiation field in a cavity. These studies lay the microscopic (quantum mechanical) foundation for Szilard-Zurek single molecule engine.

description: We investigate the possibility that stellar mass black holes, with masses in the range of $3.8M_{\odot}$ and $6M_{\odot}$, respectively, could be in fact quark stars in the Color-Flavor-Locked (CFL) phase. Depending on the value of the gap parameter, rapidly rotating CFL quark stars can achieve much higher masses than standard neutron stars, thus making them possible stellar mass black hole candidates. Moreover, quark stars have a very low luminosity and a completely absorbing surface - the infalling matter on the surface of the quark star is converted into quark matter. A possibility of distinguishing CFL quark stars from stellar mass black holes could be through the study of thin accretion disks around rapidly rotating quark stars and Kerr type black holes, respectively. Furthermore, we show that the radiation properties of accretion disks around black holes and CFL quark stars are also very similar. However, strange stars exhibit a low luminosity, but high temperature bremsstrahlung spectrum, which, in combination with the emission properties of the accretion disk, may be the key signature to differentiate massive strange stars from black hole.

Publisher: name: INFN Open Access Repository
Year: 1992

description: We describe the physics which can be done at DAPHNE, the \π factory under construction at the Laboratori Nazionali di Frascati dell'INFN, which includes: (1) The complete determination of 16 independent parameters which describe the K_S-K_L system, mostly through precision interferometry between pairs of same, different, and one versus sum of the other (inclusive) final states. These measurements allow independent determinations of the five (CPT) violating parameters, as well as high precision determinations of three (CP) violation parameters, which include R(ε'/ε) and I(ε'/ε). R(ε'/ε) can also be determined to an equivalent accuracy using the 'double ratio' method, and ε from precision measurements of asymmetries in K_L semileptonic decays. (2) The first probable observation of CP violation in the K_S system by seeing K_S->π^0π^0π^0 events, and asymmetries in rates of K_S semileptonic decays. (3) Searches for other direct CP violating effects in asymmetries in neutral and charged K->3π decay distributions and in K_+-->π^+-π^0γ decay rates. (4) Precision measurements of the form factors in K semileptonic decays and tests of Chiral Perturbation Theory. (5) Studies of radiative \\decays to resolve puzzles in light meson spectroscopy. (6) The study of K-nucleon interaction. (7) The study of hypernuclei formation and decay. All but the last topic can be studied using the general purpose detector KLOE, which is being designed and built for running at DAPHNE. A special purpose detector, FINUDA. is being proposed for hypernuclei physics.

description: A series of quinazoline derivatives with benzylidene hydrazine carboxamide were designed and synthesised as EGFR inhibitors. Most compounds exhibited exceptional anti-proliferative activity against A549, HepG2, MCF-7 and H1975 cells. Furthermore, six compounds demonstrated excellent inhibition activity against EGFRWT with the IC50 value both less than 2 nM. Among the six compounds, 44 exhibited the strongest activity (0.4 nM) and potently inhibited EGFRL858R/T790M (0.1 μM). Excitingly, the most potent compound 14 showed excellent enzyme inhibitory activity with 6.3 nM and 8.4 nM for both EGFRWT and EGFRT790M/L858R. The result of AO single staining and Annexin V/PI staining showed that the compound 14 and 44 could induce remarkable apoptosis of A549 cells. The compound 14 arrested the cell cycle at the S phase and compound 44 arrested the cell cycle at the G0 phase in A549 cells. These preliminary results demonstrate that compound 14 and 44 may be promising lead compound-targeting EGFR.

description: We study plasma effects on radiative transitions (e.g., decay of excited states of atoms or atomic nuclei) in a dense plasma at the transition frequencies $ω\lesssim ω_p$ (where $ω_p$ is the electron plasma frequency). The decay goes through four channels -- the emission of real transverse and longitudinal plasmons as well as the emission of virtual transverse and longitudinal plasmons with subsequent absorption of such plasmons by the plasma. The emission of real plasmons dies out at $ω\leq ω_p$, but the processes with virtual plasmons strongly enhance the radiative decay. Applications of these results to radiative processes in white dwarf cores and neutron star envelopes are discussed.

The model is based on minimal assumptions: some rotating compact relativistic object at the center and stable perturbations of its rotating gravitational field, described by Teukolsky Master Equation. We show that using nonstandard polynomial solutions to the angular Teukolsky equation we can describe the formation of collimated jets of various forms. Appearance of imaginary part of the superradiance-like frequency is established for the first time for pure vacuum black hole jet solutions of Teukolsky equation.

Some Problems of Meson Spectroscopy. Possible Solutions at DAFNE

Year: 1992

description: The e^+e^- collider with luminosity of the order of 10^32 - 10^33 cm^-2s-1 in the energy range √s = 1-2 GeV is a very good facility to study hadron physics. We discuss here some problems of meson specroscopy, namely the problem of radial and orbital vector meson excitations and their electromagnetic widths, the two particle decays of vector mesons and the level structure of P-wave meson multiplets. In the first two cases one can study the vector mesons produced in s-channel. In the last case the study of radiative decays of ρ(1700) meson into P-wave states gives a possibility to discriminate between different candidates for P-wave multiplet members.
L'ecole de Quebec et l'influence francaise

Publisher: name: University of British Columbia
Year: 2011

description: Cette thèse a pour but l'examen des influences de la poésie française sur la poésie canadienne-française entre 1850 et 1895, dates qui représentent la période de l'essor de la poésie romantique à Québec. Puisque le romantisme au Canada a été traité en profondeur, cette étude vise plutôt a faire ressortir l'influence d’autres mouvements importants en France à cette époque. Le premier chapitre examine le milieu d'où jaillit l'Ecole de Québec pour établir dans quelle mesure les conditions économiques, politiques et commerciales tendaient à décourager l’épanouissement d'une littérature indigène et à rendre l'influence, une fois accessible, des lettres françaises d'autant plus inévitable. Bien qu’il soit nécessaire des l'abord d’établir cette accessibilité, le procédé principal de cette étude consiste en l'examen de l'évidence interne des influences françaises dans les écrits des poètes les plus importants pour le développement de la poésie canadienne-française vers l'autonomie. Cet examen cherche à préciser non seulement les sources en soi mais aussi leur caractère, leur étendue, et leur prédominance relative vis-à-vis de l'originalité créatrice dans ces écrits. Il est impossible de ne pas reconnaître l’importance des emprunts conscients et voulus, puisés dans le fond d'un tel poète français, surtout dans le cas dfun grand nombre d’imitations qui font partie de l'oeuvre canadienne-française a ses debuts. Mais, croyant avec G. Bessette (Les Images en Poésie Canadienne-française) que les emprunts inconscients, automatiques, sont les plus signifiants pour l’investigateur de sources, l'auteur de cette étude s'appuie sur l'analyse objective de la forme - lexique, images, prosodie - pour mettre en relief les inspirations profondes qui influèrent sur la poesie de l'Ecole de Québec. Cette thèse affirme, selon le témoignage de la poésie d’Octave Crémazie, Pamphile Lemay et Nérée Beauchemin, l'éclectisme répandu de la poésie canadienne au xixe siècle, un éclectisme qui, malgré la ténacité de l'école romantique, fit appel aux precédés poétiques des mouvements parnassien et post-parnassien dans une mesure jusqu'ici négligée.

description: Aerial displays of starlings (Sturnus vulgaris) at their communal roosts are complex: thousands of individuals form multiple flocks which are continually changing shape and density, while splitting and merging. To understand these complex displays both empirical data and models are needed. Whereas detailed empirical data were recently collected through video recordings and position measurements by stereo photography of flocks of thousands of starlings, there are as yet no models that generate these complex patterns. Numerous computer models in biology, however, suggest that patterns of single groups of moving animals may emerge by self-organisation from movement and local coordination (through attraction, alignment and avoidance of collision). In this paper, we investigated whether this approach can be extended to generate patterns resembling these aerial displays of starlings. We show in a model that to generate many of the patterns measured empirically in real starlings we have to extend the usual rules of local coordination with specifics of starling behaviour, mainly 1) their aerial locomotion, 2) a low and constant number of interaction-partners and 3) preferential movement above a roosting area. Our model can be used as a tool for the study of these displays, because it provides new integrative hypotheses about the mechanisms underlying these displays and of swarming patterns in biological systems in general.

Friction induced vibration
Creators: name: Cameron, Roderick
Publisher: name: University of British Columbia
Year: 2011

description: Frictional vibrations have been induced in a system having an elastically suspended,and viscously damped slider loaded onto a surface driven-at constant velocity. Exact mathematical analysis-of the system reveals a unique value of the driven surface velocity, above which frictional vibrations of the slider cannot exist. Theory suggests that the "critical" value-of the driven surface velocity is dependent upon the damping, load, and stiffness of the suspension, and the friction characteristics-of the rubbing surfaces. Using the approximation that the amplitude of stick of the slider equals the maximum amplitude of vibration, a relationship is developed which predicts the amplitude of vibration at any given value of driven surface velocity. The limiting velocity of this function when the amplitude tends to zero is the critical velocity. Exact and approximate theories are compared for specific practical cases, and reasonable agreement is found. Five systems were investigated experimentally, and displacement-time charts of the slider were obtained at different values of the driven surface velocity. Unstable regions were noted where the slider fluctuated between smooth sliding and frictional vibrations. The experimental data illustrates the existence of a critical velocity of the driven surface, and its dependence upon the degree of damping in the system. The correlation between experimental data and theoretical curves indicates that the developed analytical method could be used to predict the behaviour of systems subject to friction induced vibrations.

description: We consider a quantum two-dimensional O(N)xO(2)/O(N-2)xO(2) nonlinear sigma model for frustrated spin systems and formulate its 1/N-expansion which involves fluctuating scalar and vector fields describing kinematic and dynamic interactions, respectively. The ground state phase diagram of this model is obtained within the 1/N-expansion and 2+εrenormalization group approaches. The temperature dependence of correlation length in the renormalized classical and quantum critical regimes is discussed. In the region of the symmetry broken ground state ρ_inρ_out or χ_in>χ_out finite-temperature properties are universal functions only at sufficiently large M_μ. The high-energy behaviour in the latter regime is similar to the Landau-pole dependence of the physical charge e in quantum electrodynamics, with mass M_μplaying a role of e^{-1}. The application of the results obtained to the triangular-lattice Heisenberg antiferromagnet is considered.

description: We fit outbursts of two X-ray novae (Nova Monocerotis 1975=A0620-00 and Nova Muscae GS 1991=1124-683) using a time-dependent accretion disk model. The model is based on a new solution for a diffusion-type equation for the non-steady-state accretion and describes the evolution of a viscous alpha-disk in a binary system after the peak of an outburst, when matter in the disk is totally ionized. The accretion rate in the disk decreases according to a power law. We derive formulas for the accretion rate and effective temperature of the disk. The model has three free input parameters: the mass of the central object M, the turbulence parameter alpha, and the normalization parameter delta t. Results of the modeling are compared with the observed X-ray and optical B and V light curves. The resulting estimates for the turbulence parameter $α$ are similar: 0.2-0.4 for A 0620-00 and 0.45-0.65 for GS 1124-683, suggesting a similar nature for the viscosity in the accretion disks around the compact objects in these sources. We also derive the distances to these systems as functions of the masses of their compact objects.

description: We investigate the dependence on length of optical fibres used in astronomy, especially the focal ratio degradation (FRD) which places constraints on the performance of fibre-fed spectrographs used for multiplexed spectroscopy. To this end we present a modified version of the FRD model proposed by Carrasco and Parry \cite{Carrasco1994} to quantify the the number of scattering defects within an optical fibre using a single parameter. The model predicts many trends which are seen experimentally, for example, a decrease in FRD as core diameter increases, and also as wavelength increases. However the model also predicts a strong dependence on FRD with length that is not seen experimentally. By adapting the single fibre model to include a second fibre, we can quantify the amount of FRD due to stress caused by the method of termination. By fitting the model to experimental data we find that polishing the fibre causes more stress to be induced in the end of the fibre compared to a simple cleave technique. We estimate that the number of scattering defects caused by polishing is approximately double that produced by cleaving. By placing limits on the end-effect, the model can be used to estimate the residual-length dependence in very long fibres, such as those required for Extremely Large Telescopes (ELTs), without having to carry out costly experiments. We also use our data to compare different methods of fibre termination.

description: We present near-infrared H2, radio CO, and thermal infrared observations of the nearby massive star-forming region Cepheus A (Cep A). From H2 bow shocks arranged along four distinct jet axes, we infer that the massive protostellar source HW2 drives a pulsed, precessing jet that has changed its orientation by about 45 degrees in roughly 104 years. The current HW2 radio jet represents the most recent event in this time series of eruptions. This scenario is consistent with the recent discovery of a disk around HW2, perpendicular to the current jet orientation, and with the presence of companions at projected distances comparable to the disk radius. We propose that the Cep A system formed by the disk-assisted capture of a sibling star by HW2. We present a numerical model of a 15 M_sun star with a circumstellar disk, orbited by a companion in an inclined, eccentric orbit. Close passages of the companion through or near the disk result in periods of enhanced accretion and mass loss, as well as forced precession of the disk and associated orientation changes in the jet. The observations reveal a second powerful outflow that emerges from radio source HW3c or HW3d. This flow is associated with blueshifted CO emission and a faint H2 bow shock to the east, and with HH 168 to the west. A collision between the flows from HW2 and HW3c/d may be responsible for X-ray and radio continuum emission in Cep A West.

description: We have studied properties and shell structure of the superheavy elements from Z=102 to Z=120 within the framework of the RMF theory. The region of study spans nuclides with neutron numbers N=150-190. The Lagrangian model NL-SV1 with the inclusion of the vector self-coupling of the omega-meson has been employed in this work. We have performed RMF + BCS calculations for an axially deformed configuration of nuclei. The ground-state binding energies, single-particle properties and quadrupole deformation of nuclei have been obtained from the mean-field minimizations. Two-neutron separation energies, $Q_α$ values and alpha-decay half-life have been evaluated. It is shown that a large number of nuclides exhibit the phenomenon of shape-coexistence over a significant region of the superheavy elements. Shape coexistence of a prolate and an oblate shape is prevalent in nuclides far below N=184, whilst nuclei in the vicinity of N=184 tend to show a shape coexistence between a spherical and an oblate shape. The shell structure and 2-neutron separation energies obtained with the RMF theory reinforce the neutron number N=184 as a major magic number. It is shown that the neutron number N=172 acts akin to a magic number in the deformed region. It is suggested that the combination Z=120 and N=172 has the potential of being a doubly magic number in the superheavy region.

description: The common probabilistic roots of the geometrical models of hadron diffraction and of the Bloch-Nordsieck theory of soft Bremsstrahlung are discussed. Their close relationship is best visible in the Chou-Yang model generalized to four dimensions. An interesting complementarity of the two descriptions in reproducing elastic scattering of high energy hadrons is pointed out.

description: A data analysis based on artificial neural network classifiers has been done to identify cosmic ray electrons and positrons detected with the balloon-borne NMSU/Wizard-TS93 experiment. The information is provided by two ancillary and independent particle detectors: a transition radiation detector and a silicon-tungsten imaging calorimeter. Electrons and positrons measured during the flight have been identified with background rejection factors of 80+ - 3 and 500 + - 37 at signal efficiencies of 72 + - 3% and 86 + - 2% for the transition radiation detector and the silicon-tungsten imaging calorimeter, respectively. The ability of the atrificial neural network classifiers to perform a careful multidimensional analysis surpassed the results achieved by conventional methods.

description: The complex AC susceptibility of high Tc superconducting materials (χ_n=χ^'_n+χ^''_n) has been described in terms of the first seven harmonic component of Fourier series. Has been measured the χ^'_n and χ^''_n (n=1,7) of sintered YBa2 Cu3O7-x (YBCO) bulk oxygen and hydrogen loaded samples versus amplitude and frequency of AC magnetic field at fixed temperature. The samples have been loaded by ms current pulses electrolysis in an aqueous solution (0.3N LiOH+H2O) at room temperature. In addition to the simplicity of the experimental setup, this procedure allows to obtain extremely high equivalent hydrogen/oxygen gas pressure on the surface of the electrodes. The YBCO electrode is polarized by short pulse width (0.5-10ms) and high power (120 W) peaks with a variable repetition rate (0.1-10000 Hz). The pulses are obtained by an home-made pulse generator. The differences in the behaviour of the susceptibilities harmonic component between the deficiency and oxygen or hydrogen loaded samples give us the possibility to connect the susceptibilities with variations of the flux pinning in respect to normal losses in the superconducting materials. The loading can be a good probe to have information on the mechanism of the processes that sustain the critical current density Jc in this situation these effects appear strongly dependent on the loading condition. By comparison of this measurements has been observed drastic change in behaviour of susceptibility.
CONSIDÉRATIONS JURIDIQUES SUR LES NOUVELLES RELATIONS ENTRE L'HOMME ET L'ABEILLE

description: Les rapports entre l’homme et l’abeille ont été profondément transformés par l’exploitation de la pollinisation.  

La raréfaction des pollinisateurs en général et de l’abeille domestique en particulier ont mis en évidence leur importance dans la production agricole et la protection de biodiversité.La mise en œuvre d’instruments juridiques propres à garantir une bonne gestion de la pollinisation n’est pas des plus évidentes, en raison de la difficulté qu’il y a à gouverner les essaims et, surtout, à en fixer les termes d’un point de vue juridique. S’il y a bien service écosystémique, la légitimité d’un paiement à l’apiculteur interroge, comme interrogent les conventions de pollinisations, à la finalité aléatoire. Des conventions à l’objet inédit (fauche tardive, jachère fleurie, etc.) permettent sans doute d’asseoir un service environnemental au profit des pollinisateurs, mais elles peinent à compenser les atteintes (épandage de pesticides par exemple) qui les affectent.
The DAFNE Cryogenic System

description: The DAFNE Project utilises superconductivity technology for a total of six superconducting magnets: the two Experiment magnets (KLOE and FINUDA) and the four Compensator Solenoid magnets needed to compensate the magnetic effect of the Experiment magnets on the electron and positron beams. This effect, on beams of 510 MeV (nominal DAFNE Energy), is expected to be relevant, especially with the aim of achieving a very high luminosity, which is the main target of the Project. The KLOE superconducting magnet has two possible working positions: the first in the DAFNE Hall, when the Experiment will be in operation, and the second one in the KLOE Assembly Hall. This second position is the first to be utilised for the KLOE magnet Acceptance Test and magnetic field mapping, prior to the mounting of all the experimental apparatus inside the magnet.This note intends to present the DAFNE Cryogenic System and how we have converged to the definition of a common Cryogenic System compatible with all the six super-conducting magnets.
