description: We report on the \textit{Fermi}-LAT observations of the Geminga pulsar, the second brightest non-variable GeV source in the $γ$-ray sky and the first example of a radio-quiet $γ$-ray pulsar. The observations cover one year, from the launch of the $Fermi$ satellite through 2009 June 15. A data sample of over 60,000 photons enabled us to build a timing solution based solely on $γ$ rays. Timing analysis shows two prominent peaks, separated by $Δϕ$ = 0.497 $\pm$ 0.004 in phase, which narrow with increasing energy. Pulsed $γ$ rays are observed beyond 18 GeV, precluding emission below 2.7 stellar radii because of magnetic absorption. The phase-averaged spectrum was fitted with a power law with exponential cut-off of spectral index $Γ$ = (1.30 $\pm$ 0.01 $\pm$ 0.04), cut-off energy $E_{0}$ = (2.46 $\pm$ 0.04 $\pm$ 0.17) GeV and an integral photon flux above 0.1 GeV of (4.14 $\pm$ 0.02 $\pm$ 0.32) $\times$ 10$^{-6}$ cm$^{-2}$ s$^{-1}$. The first uncertainties are statistical and the second are systematic. The phase-resolved spectroscopy shows a clear evolution of the spectral parameters, with the spectral index reaching a minimum value just before the leading peak and the cut-off energy having maxima around the peaks. Phase-resolved spectroscopy reveals that pulsar emission is present at all rotational phases. The spectral shape, broad pulse profile, and maximum photon energy favor the outer magnetospheric emission scenarios.

description: Questa ricerca concerne l’insegnamento della probabilità alla scuola media. Dapprima si descrive lo stato attuale dell’insegnamento della probabilità nelle classi di scuola media del Cantone attraverso l’analisi di quattro interviste a docenti e a esperti. In seguito si presenta un percorso didattico di introduzione al calcolo delle probabilità in una seconda media. Partendo da un’indagine sulle convinzioni iniziali degli allievi, si propongono delle attività legate alla scoperta del concetto di probabilità matematica, valutando con un test le competenze acquisite. Con l’indagine finale si sono raccolti i dati allo scopo di osservare l’effetto dell’intervento didattico e il cambiamento delle convinzioni dei ragazzi. I risultati emersi dalla ricerca mostrano che, sebbene pochi docenti insegnino la probabilità alla scuola media, i ragazzi dopo un intervento didattico adeguato migliorano le competenze e correggono le loro eventuali convinzioni sbagliate.

The stochastic reflection problem on an infinite dimensional convex set and BV functions in a Gelfand triple

description: In this paper, we introduce a definition of BV functions in a Gelfand triple which is an extension of the definition of BV functions in [2] by using Dirichlet form theory. By this definition, we can consider the stochastic reflection problem associated with a self-adjoint operator $A$ and a cylindrical Wiener process on a convex set $Γ$ in a Hilbert space $H$. We prove the existence and uniqueness of a strong solution of this problem when $Γ$ is a regular convex set. The result is also extended to the non-symmetric case. Finally, we extend our results to the case when $Γ=K_α$, where $K_α={f\in L^2 (0,1)|f\geq -α},α\geq0$.
Evaluating the impact of UBC’s ‘walk and roll to school week’ program on children’s active travel mode share to school
Creators: name: Nasim, Usman
Publisher: name: University of British Columbia
Year: 2020

description: With the rise of physical inactivity among children, there has been a decline in children’s active school travel (AST) like walking and bicycling to and from school. The school journeys are a prime opportunity for introducing children to active travel modes. To address lack of physical activity and a decline in AST among children, a variety of transportation policies and programs have been developed. The objective of this thesis is to evaluate the impact of the School Travel Planning (STP) encouragement program on children’s active travel mode share to school. A quasi-experimental design was used to compare active mode share at two elementary schools that organize a ‘Walk and Roll to School’ (WNR) week program with two control schools in Vancouver, British Columbia. The observational counts were carried out at the four study schools to collect data on children’s mode of travel to school. The counts were conducted in four waves. A difference-in-differences approach was used to estimate the intervention effect of the WNR week program. An audit of pedestrian and bicycling facilities was also conducted near the study schools to assess infrastructure barriers to AST. The results from the study suggest no significant immediate impact of the WNR week program on children’s active mode share (walking, bike, and other non-motorized modes like scooter, skateboard, and rollerblade) to school during or shortly after the WNR week. Changes in active mode share to study schools over the weeks investigated were not significantly different from those in the control schools and appeared to be primarily influenced by the weather and daylight conditions. However, because the WNR week is an ongoing annual event at the school since 2013, there could be a long-term positive effect on AST, which was present in the “before” observation and not be observed in this study. It is recommended to possibly consider implementing alternatives to STP interventions to influence children’s travel behaviour to schools for achieving immediate and short term gains. Also, studying the long term impacts of STP programs on children’s AST rates to and from schools and to include control schools in analysis for future research.

description: The article is concerned with the function of music in the 17th and 18th centuries as a means of communication. Since his youth, the author has immersed himself in historical sources on the art of composition and has acquired the ability to compose in various baroque styles. He takes care to follow the working method of a baroque composer as consistently as possible. First, he gives a brief outline of where his interest in composing in historical styles originated. The main section of the article discusses the various compositional means that composers used to write music that expressed the particular affections of the underlying texts and let the listeners feel them for themselves. The composers used the art of rhetoric as a model when approaching the compositional process. Finally, on the basis of two of his own works, the author provides insights into his working methods. An Entrée in the French style serves as an example for the composition of instrumental music. With the help of a recitative from a completion of Bach's lost score of the St. Mark Passion, the author explains various aspects of vocal composition; the difficulties in dealing with prose texts; and his own possible solutions to them.

description: Seven years of pulse time-of-arrival measurements have been collected from observations of the young pulsar PSR B2334+61 using the Nanshan radio telescope of Urumqi Observatory. A phase-connected solution has been obtained over the whole data span, 2002 August to 2009 August. This includes a very large glitch that occurred between 2005 August 26 and September 8 (MJDs 53608 and 53621). The relative increase in rotational frequency for this glitch, $Δν_{g}/ν~\sim~20.5\times10^{-6}$, is the largest ever seen. Although accounting for less than 1\% of the glitch, there were two well-defined exponential decay terms with time constants of 21 and 147 days respectively. There was also a large long-term increase in the spindown rate with $Δ\dotν_p/\dotν\sim 0.011$ at the time of the glitch. A highly significant oscillation with a period of close to one year is seen in the post-glitch residuals. It is very unlikely that this can be accounted for by a pulsar position error or proper motion -- it appears to result from effects interior to the neutron star. Implications of these results for pulsar glitch models are discussed.

description: This article focuses on the key teaching principles of Leopold Auer, a Hungarian violinist, who is considered the founder of Russian Violin School. The author enumerates some of Leopold Auer’s students and followers who have brought fame to their outstanding tutor all over the world, including Vietnam, thus greatly influencing the local teachers and performers. The author highlights the difference between music and science, and the corresponding peculiarities of teaching this kind of exquisite art. Taking into account the academic principles described in Leopold Auer’s book “My Violin School”, the author comes to the conclusion that the teacher should not just share their knowledge with their student, but also instill their character, develop their creative potential, be persuasive and sympathetic, thus forming and developing students' harmonious personality. In conclusion, the author points out that a good teacher should not necessarily be a good performer as well because he has a more important and worthwhile goal – to help their student open up their potential and outperform their tutor.

Genomic associations of Listeria monocytogenes adhesion at 8°C

description: Listeria monocytogenes, a highly virulent foodborne pathogen, remains a threat to the food system and has led to numerous foodborne outbreaks worldwide. L. monocytogenes can establish itself in food production facilities by adhering to surfaces, resulting in increased resistance to environmental stressors. The aim of this study was to evaluate the adhesion ability of a collection of L. monocytogenes at 8°C and to analyse associations between the observed phenotypes and genetic factors such as internalin A (inlA), stress survival islet 1 (SSI-1), and clonal complex (CC). L. monocytogenes isolates (n=184) were grown at 8°C and 100% relative humidity. Growth was determined by measurement of optical density at 600 nm. Adherent cells were stained using crystal violet and quantified spectrophotometrically at 595 nm. Genotyping of inlA and SSI-1, multi-locus sequence typing, and a genome wide association were performed to elucidate the phenotype-genotype relationships in L. monocytogenes cold adhesion. Among all inlA genotypes, truncated inlA isolates had the highest mean adhered cells (ANOVA; P<0.05), while isolates with the three-codon deletion inlA had the least mean adhered cells (ANOVA; P<0.05). When SSI-1 was present, more cells were adhered; and less cells were adhered when SSI-1 was absent (Welch’s t-test; P<0.05). Increased adhesion was associated with clonal complexes with low clinical frequency while lack of adhesion was associated with clonal complexes with high clinical frequency. A genome wide association study revealed genes which were not previously known to be associated with 8°C adhesion. The associations of genotype and 8°C adhesion suggests that there may be an evolutionary trade off between virulence and adhesion in L. monocytogenes.

description: We show that standard Relativistic Dynamics Equation F=dp/dτis only partially covariant. To achieve full Lorentz covariance, we replace the four-force F by a rank 2 antisymmetric tensor acting on the four-velocity. By taking this tensor to be constant, we obtain a covariant definition of uniformly accelerated motion. We compute explicit solutions for uniformly accelerated motion which are divided into four types: null, linear, rotational, and general. For null acceleration, the worldline is cubic in the time. Linear acceleration covariantly extends 1D hyperbolic motion, while rotational acceleration covariantly extends pure rotational motion. We use Generalized Fermi-Walker transport to construct a uniformly accelerated family of inertial frames which are instantaneously comoving to a uniformly accelerated observer. We explain the connection between our approach and that of Mashhoon. We show that our solutions of uniformly accelerated motion have constant acceleration in the comoving frame. Assuming the Weak Hypothesis of Locality, we obtain local spacetime transformations from a uniformly accelerated frame K' to an inertial frame K. The spacetime transformations between two uniformly accelerated frames with the same acceleration are Lorentz. We compute the metric at an arbitrary point of a uniformly accelerated frame. We obtain velocity and acceleration transformations from a uniformly accelerated system K' to an inertial frame K. We derive the general formula for the time dilation between accelerated clocks. We obtain a formula for the angular velocity of a uniformly accelerated object. Every rest point of K' is uniformly accelerated, and its acceleration is a function of the observer's acceleration and its position. We obtain an interpretation of the Lorentz-Abraham-Dirac equation as an acceleration transformation from K' to K.

description: The Doi formalism treats a reaction-diffusion process as a quantum many-body problem. We use this second quantized formulation as a starting point to derive a numerical scheme for simulating $X\to 0$ reaction-diffusion processes, following a well-established time discretization procedure. In the case of a reaction zone localized in the configuration space, this formulation provides also a systematic way of designing an optimized, multiple time step algorithm, spending most of the computation time to sample the configurations where the reaction is likely to occur.

description: We study which rational points of the Jacobian of P^1_K -{0,1,infty} can be lifted to sections of geometrically 3 nilpotent quotients of etale pi_1 over the absolute Galois group. This is equivalent to evaluating certain triple Massey products of elements of H^1(G_K). For K=Q_p or R, we give a complete mod 2 calculation. This permits some mod 2 calculations for K = Q. These are computations of obstructions of Jordan Ellenberg.

description: In operational networks, nodes are connected via multiple links for load sharing and redundancy. This is done to make sure that a failure of a link does not disconnect or isolate some parts of the network. However, link failures have an effect on routing, as the routers find alternate paths for the traffic originally flowing through the link which has failed. This effect is severe in case of failure of a critical link in the network, such as backbone links or the links carrying higher traffic loads. When routing is done using the Open Shortest Path First (OSPF) routing protocol, the original weight selection for the normal state topology may not be as efficient for the failure state. In this paper, we investigate the single link failure issue with an objective to find a weight setting which results in efficient routing in normal and failure states. We engineer Tabu Search Iterative heuristic using two different implementation strategies to solve the OSPF weight setting problem for link failure scenarios. We evaluate these heuristics and show through experimental results that both heuristics efficiently handle weight setting for the failure state. A comparison of both strategies is also presented.
On the dynamics of planetesimals embedded in turbulent protoplanetary discs

Year: 2010
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: (abridged) Angular momentum transport and accretion in protoplanetary discs are generally believed to be driven by MHD turbulence via the magneto-rotational instability (MRI). The dynamics of solid bodies embedded in such discs (dust grains, boulders, planetesimals and planets) may be strongly affected by the turbulence, such that the formation pathways for planetary systems are determined in part by the strength and spatial distribution of the turbulent flow. We examine the dynamics of planetesimals, with radii between 1m â 10 km, embedded in turbulent protoplanetary discs, using three dimensional MHD simulations. The planetesimals experience gas drag and stochastic gravitational forces due to the turbulent disc. We use, and compare the results from, local shearing box simulations and global models in this study. The main aims of this work are to examine: the growth, and possible saturation, of the velocity dispersion of embedded planetesimals as a function of their size and disc parameters; the rate of radial migration and diffusion of planetesimals; the conditions under which the results from shearing box and global simulations agree. We find good agreement between local and global simulations when shearing boxes of dimension 4H x 16H x 2H are used (H being the local scale height). The magnitude of the density fluctuations obtained is sensitive to the box size, due to the excitation and propagation of spiral density waves. This affects the stochastic forcing experienced by planetesimals. [...] Our models show that fully developed MHD turbulence in protoplanetary discs would have a destructive effect on embedded planetesimals. Relatively low levels of turbulence are required for traditional models of planetesimal accretion to operate, this being consistent with the existence of a dead zone in protoplanetary discs.

description: Fluid instabilities like Rayleigh-Taylor,Richtmyer-Meshkov and Kelvin-Helmholtz instability can occur in a wide range of physical phenomenon from astrophysical context to Inertial Confinement Fusion(ICF).Using Layzer's potential flow model, we derive the analytical expressions of growth rate of bubble and spike for ideal magnetized fluid in R-T and R-M cases. In presence of transverse magnetic field the R-M and R-T instability are suppressed or enhanced depending on the direction of magnetic pressure and hydrodynamic pressure. Again the interface of two fluid may oscillate if both the fluids are conducting. However the magnetic field has no effect in linear case.
Predicting dust extinction from the stellar mass of a galaxy

description: We investigate how the typical dust extinction of H-alpha luminosity from a star-forming galaxy depends upon star formation rate (SFR), metallicity and stellar mass independently, using a sample of ~90,000 galaxies from Data Release 7 of the Sloan Digital Sky Survey (SDSS). We measure extinctions directly from the Balmer decrement of each source, and while higher values of extinction are associated with an increase in any of the three parameters, we demonstrate that the fundamental property that governs extinction is stellar mass. After this mass-dependent relationship is removed, there is very little systematic dependence of the residual extinctions with either SFR or metallicity, and no significant improvement is obtained from a more general parameterisation. In contrast to this, if either a SFR-dependent or metallicity-dependent extinction relationship is applied, the residual extinctions show significant trends that correlate with the other parameters. Using the SDSS data, we present a relationship to predict the median dust extinction of a sample of galaxies from its stellar mass, which has a scatter of ~0.3 mag. The relationship was calibrated for H-alpha emission, but can be more generally applied to radiation emitted at other wavelengths. These results have important applications for studies of high-redshift galaxies, where individual extinction measurements are hard to obtain but stellar mass estimates can be relatively easily estimated from long-wavelength data.

Hemilabile heteroelement based ligands for early transition metal complexes, fundamental studies and applications to catalysis
Creators: name: Thibault, Bagnol
Publisher: name: University of British Columbia
Year: 2020

description: This thesis details the development of new hemilabile ligands using heteroelement chemistry to develop new precatalyst for hydrofunctionalization chemistry. These chelating molecules are studied with early transition metals from group 4 and 5 as titanium, zirconium and tantalum. Synthesis of 1,3-N,O-chelating complexes containing boron atom have been synthesized using a new synthetic pathway based on electrophilic Friedel-Crafts reaction that involves amineborane complexes. Coordination chemistry with titanium is studied and shows unexpected reactivity with formation of another product. 1,3-N,N-chelating complexes containing boron were investigated through two different aspects, either using cyclic or acyclic boraamidines. A four step synthesis involving subsequent borylation and Suzuki-Miyaura cross-coupling reactions is developed, to obtain cyclic boraamidine. Acyclic boraamidines were synthesized using procedures from the literature. Coordination chemistry involving early transition metals was carried out, and catalytic hydroaminoalkylation examined. Complementary to this work, another synthetic approach on order to obtain beta-aminophosphine ligands was looked at. Hydroamination of alkynes has been reported several times in the literature using either aryl or alkyl alkynes. Besides, alkynes containing heteroelements such as phosphorus remains evasive. N,P,N-type ligands were synthesized and protonolysis reactions were carried out to achieve the formation of new N,P,N-metal complexes containing early transition metals like titanium and zirconium.

The phase behavior is found to be hybrid between the Gaussian core and penetrable sphere models. The system additionally exhibits a series of reentrant crystallization and melting loops as well as critical isostructural transitions between crystals of different occupancy. Due to the creation and annihilation of lattice sites, the system further shows an unusual and intriguing softening upon compression.

description: In the Next-to-Minimal Supersymmetric Standard Model, a bino-like LSP can be as light as a few GeV and satisfy WMAP constraints on the dark matter relic density in the presence of a light CP-odd Higgs scalar. We study upper bounds on the direct detection cross sections for such a light LSP in the mass range 2-20 GeV in the NMSSM, respecting all constraints from B-physics and LEP. The OPAL constraints on e^+ e^- -> χ^0_1 χ^0_i (i > 1) play an important role and are discussed in some detail. The resulting upper bounds on the spin-independent and spin-dependent nucleon cross sections are ~ 10^{-42} cm^{-2} and ~ 4\times 10^{-40} cm^{-2}, respectively. Hence the upper bound on the spin-independent cross section is below the DAMA and CoGeNT regions, but could be compatible with the two events observed by CDMS-II.

description: We prove the nonexistence of stable immersed minimal surfaces uniformly conformally equivalent to the complex plane in any complete orientable four-dimensional Riemannian manifold with uniformly positive isotropic curvature. We also generalize the same nonexistence result to higher dimensions provided that the ambient manifold has uniformly positive complex sectional curvature. The proof consists of two parts, assuming an "eigenvalue condition" on the Cauchy-Riemann operator of a holomorphic bundle, we prove (1) a vanishing theorem for these holomorphic bundles on the complex plane; (2) an existence theorem for holomorphic sections with controlled growth by Hormander's weighted L^2-method.

description: Electronic devices compliance has become one of the fundamental parts of the whole product development. In fact, manufacturers have to look for new and ingenious solutions in order to deliver a fabulous product that complies with the current norms. Wireless device manufacturers have recently developed techniques to ensure compliance of their products with limits for human exposure to radio-frequency electromagnetic fields. A commonly used technique is to reduce the output power when the user is in direct contact with the device. Regulatory agencies that want to test the devices have to measure these sensors/behaviours manually, which is very time consuming and limits the number of use conditions that can be tested. These tests are currently performed by approaching the device to an ideally infinite plane that simulates the human body (similar dielectric material).

description: We develop a theory of energy relaxation and thermalization of hot carriers in real quantum wires. Our theory is based on a controlled perturbative approach for large excitation energies and emphasizes the important roles of the electron spin and finite temperature. Unlike in higher dimensions, relaxation in one-dimensional electron liquids requires three-body collisions and is much faster for particles than holes which relax at nonzero temperatures only. Moreover, co-moving carriers thermalize more rapidly than counterpropagating carriers. Our results are quantitatively consistent with a recent experiment.

La ricerca che segue vuole promuovere un'esperienza educativa di crescita personale proponendo un percorso di narrazione di sé attraverso la metafora del seme. Si indaga se mediante questa pratica educativa gli allievi siano aiutati a raccontarsi e di conseguenza siano stimolati a migliorare la loro relazione con il docente e i compagni. Offrendo loro la possibilità di svolgere un'esperienza pratica, quale la coltivazione individuale di alcune piantine in classe, si aspira a capire se quest'ultima sviluppi la dimensione del prendersi cura. Dalla creazione di un proprio libro-orto e la relativa raccolta di dati, accompagnata da discussioni collettive, registrazioni, fotografie, testi e notevoli attività pratiche svolte sia all'aperto che in classe, così come la cura di un cestino contenente diversi tipi di semi, risulta che gli allievi riescono, in maniera spontanea e naturale, a narrare di sé; di conseguenza vi è un'influenza positiva anche sulle relazioni sociali presenti in classe. I dati raccolti, confermano che la pratica educativa di cura promuove il raccontarsi, sviluppa un atteggiamento responsabile nell'allievo e contribuisce alla creazione di una continuità tra scuola e famiglia. I risultati dimostrano che il libro-orto ha influenzato positivamente l'allievo permettendogli di valorizzare la sua creatività e di attivare durante il percorso diverse competenze per reperire e acquisire nuove conoscenze.

description: The water wave theory traditionally assumes the fluid to be perfect, thus neglecting all effects of the viscosity. However, the explanation of several experimental data sets requires the explicit inclusion of dissipative effects. In order to meet these practical problems, the theory of visco-potential flows has been developed (see P.-F. Liu & A. Orfila (2004) and D. Dutykh & F. Dias (2007)). Then, usually this formulation is further simplified by developing the potential in an entire series in the vertical coordinate and by introducing thus, the long wave approximation. In the present study we propose a derivation of dissipative Boussinesq equations which is based on asymptotic expansions of the Dirichlet-to-Neumann (D2N) operator. Both employed methods yield the same system by different ways.

description: Peripheral collisions with radioactive heavy-ion beams at relativistic energies are discussed as an innovative approach for probing the transient regime experienced by fissile systems evolving towards quasi-equilibrium. A dedicated experiment using the advanced technical installations of GSI, Darmstadt, permitted to realize ideal conditions for the investigation of relaxation effects in the meta-stable well. Combined with a highly sensitive experimental signature, it provides a measure of the transient effects with respect to the flux over the fission barrier. Within a two-step reaction process, 45 proton-rich unstable spherical isotopes produced by projectile-fragmentation of a stable 238U beam have been used as secondary projectiles. The fragmentation of the radioactive projectiles on lead results in nearly spherical compound nuclei which span a wide range in excitation energy and fissility. The decay of these excited systems by fission is studied with a dedicated set-up which permits the detection of both fission products in coincidence and the determination of their atomic numbers with high resolution. The width of the fission-fragment nuclear charge distribution is shown to be specifically sensitive to pre-saddle transient effects and is used to establish a clock for the passage of the saddle point. The comparison of the experimental results with model calculations points to a fission delay of (3.3+/-0.7).10-21s for initially spherical compound nuclei, independent of excitation energy and fissility. This value suggests a nuclear dissipation strength at small deformation of (4.5+/-0.5).1021s-1. The very specific combination of the physics and technical equipment exploited in this work sheds light on previous controversial conclusions.
