An ultraviolet completion for the Scotogenic model
Creators: name: Escribano, Pablo
name: Vicente, Avelino
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The Scotogenic model is an economical scenario that generates neutrino masses at the 1-loop level and includes a dark matter candidate. This is achieved by means of an ad-hoc $\mathbb{Z}_2$ symmetry, which forbids the tree-level generation of neutrino masses and stabilizes the lightest $\mathbb{Z}_2$-odd state. Neutrino masses are also suppressed by a quartic coupling, usually denoted by $λ_5$. While the smallness of this parameter is natural, it is not explained in the context of the Scotogenic model. We construct an ultraviolet completion of the Scotogenic model that provides a natural explanation for the smallness of the $λ_5$ parameter and induces the $\mathbb{Z}_2$ parity as the low-energy remnant of a global $\rm U(1)$ symmetry at high energies. The low-energy spectrum contains, besides the usual Scotogenic states, a massive scalar and a massless Goldstone boson, hence leading to novel phenomenological predictions in flavor observables, dark matter physics and colliders.

Symmetries of some motivic integrals

Publisher: name: arXiv

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: We give an explicit formula for the motivic integrals related to the Milnor number over spaces of parametrised arcs on the plane with fixed tangency orders with the axis. These integrals are rational functions of the parameters and the class of the affine line. Using a set of natural recurrence relations between them, we prove an unexpected invariance property with respect to the simultaneous inversion of the parameters and the class of the affine line. We also discuss a generalization of this system of recurrence relations whose solutions are also symmetric and satisfy additional differential equations.

Duration and bond returns : empirical tests
Creators: name: Freedman, Ruth Janine
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is to empirically investigate the role of duration in explaining bond price volatility caused by interest rate movements. Specifically, Canadian and American market data are used to test whether Macaulay/Fisher and Weil duration is an adequate measure of basis risk for default-free government bonds during the 20-year sample period January 1961 to December 1980. The most important result of the study is that in either a Canadian or an American context there is no significant evidence to suggest that, on average, higher duration bonds earn higher returns. Specifically, there appears to be a negative, although insignificant, relationship on average between bond returns and duration. A possible explanation for this result is that interest rates have trended upwards over most of the sample period. American results suggest that when changes in the level of interest rates have been filtered out there is a positive, although insignificant, relationship between bond returns and duration. Other results of the study are that coupon rates are positively related to bond returns (perhaps due to a tax effect), and that bond pricing errors are often related to subsequent returns.

Monte Carlo investigation of the magnetic anisotropy in Fe/Dy multilayers

Publisher: name: arXiv
Year: 2008
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: By Monte Carlo simulations in the canonical ensemble, we have studied the magnetic anisotropy in Fe/Dy amorphous multilayers. This work has been motivated by experimental results which show a clear correlation between the magnetic perpendicular anisotropy and the substrate temperature during elaboration of the samples. Our aim is to relate macroscopic magnetic properties of the multilayers to their structure, more precisely their concentration profile. Our model is based on concentration dependent exchange interactions and spin values, on random magnetic anisotropy and on the existence of locally ordered clusters that leads to a perpendicular magnetisation. Our results evidence that a compensation point occurs in the case of an abrupt concentration profile. Moreover, an increase of the noncollinearity of the atomic moments has been evidenced when the Dy anisotropy constant value grows. We have also shown the existence of inhomogeneous magnetisation profiles along the samples which are related to the concentration profiles.
From carriers and virtual excitons to exciton populations: Insights into time-resolved ARPES spectra from an exactly solvable model
Creators: name: Stefanucci, G.

Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: We calculate the {\em exact} time-resolved ARPES spectrum of a two-band model semiconductor driven out of equilibrium by resonant and nonresonant laser pulses, highlighting the effects of phonon-induced decoherence and relaxation. {\em Resonant} excitations initially yield a replica of the {\em valence} band shifted upward by the energy of the exciton peak in photoabsorption. This phase is eventually destroyed by phonon-induced decoherence: the valence-band replica lowers in energy by the Stokes shift, locating at the energy of the exciton peak in photoluminescence, and its width grows due to phonon dressing. {\em Nonresonant} excitations initially yield a map of the conduction band. Then electrons transfer their excess energy to the lattice and bind with the holes left behind to form excitons. In this relaxed regime a replica of the {\em conduction} band appears inside the gap. At fixed momentum the lineshape of the conduction-band replica versus the photoelectron energy is proportional to the exciton wavefunction in "energy space" and it is highly asymmetric. Although the two-band model represents an oversimplified description of real materials the highlighted features are qualitative in nature; hence they provide useful insights into time-resolved ARPES spectra and their physical interpretation.

Green-Schwarz and Pure Spinor Formulations of Chiral Strings
Creators: name: Guillen, Max
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Bosonic and RNS chiral strings have been defined from a singular gauge fixing of the respective Polyakov and spinning string actions, enforcing, among other things, the finite nature of their physical spectra. Except for the heterotic case, the tensionless limits of such chiral models have been shown to describe the same field theories predicted by their ambitwistor analogues. In this paper, we study the Green-Schwarz formulation for Type II and heterotic superstrings in a singular gauge. After performing a light-cone gauge analysis, their physical spectra are shown to match those of RNS chiral strings, and their respective tensionless limits are found to describe the same field theories predicted by RNS ambitwistor strings. Their pure spinor counterparts are then introduced by making use of the Oda-Tonin method. In doing so, symmetries hidden in the pure spinor ambitwistor string action become manifest, proposals motivating the sectorized pure spinor BRST charges find simple grounds, and integrated vertex operators emerge naturally.

description: We show how the quantum analog of the Fokker-Planck equation for describing Brownian motion can be obtained as the diffusive limit of the quantum linear Boltzmann equation. The latter describes the quantum dynamics of a tracer particle in a dilute, ideal gas by means of a translation-covariant master equation. We discuss the type of approximations required to obtain the generalized form of the Caldeira-Leggett master equation, along with their physical justification. Microscopic expressions for the diffusion and relaxation coefficients are obtained by analyzing the limiting form of the equation in both the Schroedinger and the Heisenberg picture.

Considering that in samples with residual resistivity of few mu-Ohm cm critical temperature variations produced by disorder effects can be comparable with variations due to the isotopic effect, we adopt a procedure in evaluating the B isotope coefficient which take account of these effects, obtaining a value which is in agreement with previous results and then confirming that there is something still unclear in the physics of MgB2.

description: L’objectif de cette étude est de déterminer les relations entre les pratiques de recrutement, de formation, des facteurs de contingence et la performance dans les PME/PMI en Guinée.

Pour y aboutir, nous avons pris en compte plusieurs directives théoriques dont les théories des pratiques des ressources humaines (Barraud-Didier et al., 2003) et de la contingence.

Il s’agira de montrer l’existence de synergie entre pratiques de GRH et facteurs de contingence permettant à l’entreprise d’atteindre la performance. A cet effet, une enquête quantitative a été menée à l’aide d’un questionnaire soumis à un échantillon probabiliste. Ce dernier est composé de 400 PME reparties dans les huit régions administratives de la Guinée.

L’analyse économétrique à l’aide du logiciel STATA (régression logistique particulièrement le logit simple) a montré que les performances organisationnelles, sociales et économiques des PME enquêtées en Guinée sont obtenues grâce aux pratiques de GRH et facteurs de contingences.

description: We have considered one-dimensional Bose-Fermi mixture with equal densities and unequal masses using numerical density matrix renormalization group (DMRG). For the mass ratio of K-Rb mixture and attraction between bosons and fermions, we determined the phase diagram. For weak boson-boson interactions, there is a direct transition between two-component Luttinger liquid and collapsed phases as the boson-fermion attraction is increased. For strong enough boson-boson interactions, we find an intermediate "paired" phase, which is a single-component Luttinger liquid of composite particles. We investigated correlation functions of such a "paired" phase, studied the stability of "paired" phase to density imbalance, and discussed various experimental techniques which can be used to detect it.

description: We propose an approach for exploiting machine learning to approximate electronic fields in crystalline solids subjected to deformation. Strain engineering is emerging as a widely used method for tuning the properties of materials, and this requires repeated density functional theory calculations of the unit cell subjected to strain. Repeated unit cell calculations are also required for multi-resolution studies of defects in crystalline solids. We propose an approach that uses data from such calculations to train a carefully architected machine learning approximation. We demonstrate the approach on magnesium, a promising light-weight structural material: we show that we can predict the energy and electronic fields to the level of chemical accuracy, and even capture lattice instabilities.

Numerical simulations of impacts involving porous bodies: I. Implementing sub-resolution porosity in a 3D SPH Hydrocode

description: In this paper, we extend our Smooth Particle Hydrodynamics (SPH) impact code to include the effect of porosity at a sub-resolution scale by adapting the so-called $P-alpha$ model. Many small bodies in the different populations of asteroids and comets are believed to contain a high degree of porosity and the determination of both their collisional evolution and the outcome of their disruption requires that the effect of porosity is taken into account in the computation of those processes. Here, we present our model and show how porosity interfaces with the elastic-perfectly plastic material description and the brittle fracture model generally used to simulate the fragmentation of non-porous rocky bodies. We investigate various compaction models and discuss their suitability to simulate the compaction of (highly) porous material. Then, we perform simple test cases where we compare results of the simulations to the theoretical solutions. We also present a Deep Impact-like simulation to show the effect of porosity on the outcome of an impact. Detailed validation tests will be presented in a next paper by comparison with high-velocity laboratory experiments on porous materials (Jutzi et al., in preparation). Once validated at small scales, our new impact code can then be used at larger scales to study impacts and collisions involving brittle solids including porosity, such as the parent bodies of C-type asteroid families or cometary materials, both in the strength- and in the gravity-dominated regime.

System tool for aircraft routing

Publisher: name: University of British Columbia
Year: 2010

description: Operations Planning at CP Air is responsible for keeping an up-to-date visual representation of the aircraft routings for the current schedule period and co-ordinating subsequent changes. Examples of changes are requests for extra usage such as charters or extra sections, changes to the maintenance schedule, and unforeseen circumstances. The present approach is a manual charting method used in the same or similar form by many airlines as well as at CP Air. This manual process is long and tedious and even minor changes can cause much work to keep the charts up-to-date and everyone informed. What is needed is an automated system that will present the information produced on the charts in the most useable manner plus the ability to make changes so that, the resulting information can be more effectively used than with the present manual method. The approach taken is the development of a. Decision Support tool that will allow Operations Planning to make decisions based on their knowledge and experience. This solution is a starting point in an area at CP Air that has long needed some automation. The system has been developed on the Virtual Machine operating system using I BrA 3279 equipment for its color capabilities, and it is currently in the stages of system testing and user-training.

description: We report on the discovery of Very High Energy (VHE) gamma-ray emission from the BL Lacertae object 1ES1011+496. The observation was triggered by an optical outburst in March 2007 and the source was observed with the MAGIC telescope from March to May 2007. Observing for 18.7 hr we find an excess of 6.2 sigma with an integrated flux above 200 GeV of (1.58$\pm0.32) 10^{-11}$ photons cm$^{-2}$ s$^{-1}$. The VHE gamma-ray flux is >40% higher than in March-April 2006 (reported elsewhere), indicating that the VHE emission state may be related to the optical emission state. We have also determined the redshift of 1ES1011+496 based on an optical spectrum that reveals the absorption lines of the host galaxy. The redshift of z=0.212 makes 1ES1011+496 the most distant source observed to emit VHE gamma-rays up to date.

description: We present low-frequency observations with the Giant Metrewave Radio Telescope (GMRT) of a sample of giant radio sources (GRSs), and high-frequency observations of three of these sources with the Very Large Array (VLA). From multifrequency observations of the lobes we estimate the magnetic field strengths using three different approaches, and show that these differ at most by a factor of $\sim$3. For these large radio sources the inverse-Compton losses usually dominate over synchrotron losses when estimates of the classical minimum energy magnetic field are used, consistent with earlier studies. However, this is often not true if the magnetic fields are close to the values estimated using the formalism of Beck & Krause. We also examine the spectral indices of the cores and any evidence of recurrent activity in these sources. We probe the environment using the symmetry parameters of these sources and suggest that their environments are often asymmetric on scales of $\sim$1 Mpc, consistent with earlier studies.

description: Generalised parton distributions are instrumental to study both the three-dimensional structure and the energy-momentum tensor of the nucleon, and motivate numerous experimental programmes involving hard exclusive measurements. Based on a next-to-leading order analysis and a careful study of evolution effects, we exhibit non-trivial generalised parton distributions with arbitrarily small imprints on deeply virtual Compton scattering observables. This means that in practice the reconstruction of generalised parton distributions from measurements, known as the deconvolution problem, does not possess a unique solution for this channel. In this Letter we discuss the consequences on the extraction of generalised parton distributions from data and advocate for a multi-channel analysis.

description: We probe the radial clumping stratification of OB stars in the intermediate and outer wind regions (r>~2 R*) to derive upper limits for mass-loss rates, and compare to current mass-loss implementation. Together with archival multi-wavelength data, our new far-infrared continuum observations for a sample of 25 OB stars (including 13 B Supergiants) uniquely constrain the clumping properties of the intermediate wind region. We derive the minimum radial stratification of the clumping factor through the stellar wind, fclmin(r), and the corresponding maximum mass-loss rate, Mdotmax, normalising clumping factors to the outermost wind region (clfar=1). The clumping degree for r>~2 R* decreases or stays constant with increasing radius for almost the whole sample. There is a dependence on luminosity class and spectral type at the intermediate region relative to the outer ones: O Supergiants (OSGs) present a factor 2 larger clumping factors than B Supergiants (BSGs). The maximum clumping of roughly 1/3 of the OB Supergiants occurs close to the wind base (r

description: We consider the moment operators of the observable (i.e. a semispectral measure or POM) associated with the balanced homodyne detection statistics, with paying attention to the correct domains of these unbounded operators. We show that the high amplitude limit, when performed on the moment operators, actually determines uniquely the entire statistics of a rotated quadrature amplitude of the signal field, thereby verifying the usual assumption that the homodyne detection achieves a measurement of that observable. We also consider, in a general setting, the possibility of constructing a measurement of a single quantum observable from a sequence of observables by taking the limit on the level of moment operators of these observables. In this context, we show that under some natural conditions (each of which is satisfied by the homodyne detector example), the existence of the moment limits ensures that the underlying probability measures converge weakly to the probability measure of the limiting observable. The moment approach naturally requires that the observables be determined by their moment operator sequences (which does not automatically happen), and it turns out, in particular, that this is the case for the balanced homodyne detector.

description: Large-scale diffuse radio emission is observed in some clusters of galaxies. There is ample of evidence that the emission has its origin in synchrotron losses of relativistic electrons, accelerated in the course of clusters mergers. In a cosmological simulation we locate the structure formation shocks and estimate their radio emission. We proceed as follows: Introducing a novel approach to identify strong shock fronts in an SPH simulation, we determine the Mach number as well as the downstream density and temperature in the MareNostrum Universe simulation which has 2x1024^3 particles in a 500 Mpc/h box and was carried out with non-radiative physics. Then, we estimate the radio emission using the formalism derived in Hoeft & Brueggen (2007) and produce artificial radio maps of massive clusters. Several of our clusters show radio objects with similar morphology to large-scale radio relics found in the sky, whereas about half of the clusters show only very little radio emission. In agreement with observational findings, the maximum diffuse radio emission of our clusters depends strongly on their X-ray temperature. We find that the so-called accretion shocks cause only very little radio emission. We conclude that a moderate efficiency of shock acceleration, namely xi_e <= 0.005, and moderate magnetic fields in the region of the relics, namely 0.07 to 0.8 muGauss are sufficient to reproduce the number density and luminosity of radio relics.

description: We present studies of quantum interference in a noise power spectrum in the system of two quantum dots (2QD) in a T-geometry. Performing the spectral decomposition we are able to separate local currents and distinguish between the intra- and inter-level current correlation contributions to the noise power spectrum. In particular, we analyzed the large bias regime and show that for a weak coupling of 2QD with the electrodes the noise power spectrum has dips at frequencies characteristic to inter-level excitations. For a strong coupling the electron transport changes its nature and the dynamics of the current correlations is different: there are two coherently coupled relaxators with different relaxation frequencies. These two regimes of current dynamics are separated by a quantum critical point, in which the noise power spectrum shows a specific frequency dependence. In the linear response limit the noise power spectrum is related to the admittance, which shows characteristics different, due to quantum interference, for the weak and strong coupling case.

description: Open quantum systems that interact with structured reservoirs exhibit non-Markovian dynamics. We present a quantum jump method for treating the dynamics of such systems. This approach is a generalization of the standard Monte Carlo Wave Function (MCWF) method for Markovian dynamics. The MCWF method identifies decay rates with jump probabilities and fails for non-Markovian systems where the time-dependent rates become temporarily negative. Our non-Markovian quantum jump (NMQJ) approach circumvents this problem and provides an efficient unravelling of the ensemble dynamics.

Co-creation activities

description: The document reports on the participatory methods and co-creation activities performed during ON-MERRIT, which constitute an integral element of the project. The co-creation activities in the project include participatory involvement in problem-formulation, methods design, and active co-construction of policy recommendations. This deliverable examines these activities, assesses stakeholder engagement and targeted engagement activities within ON-MERRIT and then summarises the outcomes of ON-MERRIT Task T2.3 (“Co-creation activities”) and provides an update on Task 2.4 (“Final validation workshop”, to take place in February 2022). The co-creation activities took place in every work package with different implementations, depending on the research needs; from community feedback to expert engagement to surveys and workshops, each of these activities aimed to verify and confirm that the research was solid and aligned with best practices. Despite the promising premises, however, the co-creation instrument proved to need careful planning and strong links with the communities we intended to engage with to ensure adequate participation. Nonetheless, the co-creation experience so far proved to be a useful tool that might be employed even beyond the SwafS projects, as a method to check the validity, on a regular basis, of research and project findings and recommendations with the stakeholders, who will be the recipients of those suggestions.

description: Heavy-flavour hadrons, i.e. hadrons containing charm or beauty quarks, are effective probes to test perturbative-QCD (pQCD) calculations, to investigate the different hadronisation mechanisms, and to study the quark-gluon plasma (QGP) produced in relativistic heavy-ion collisions at the LHC. Measurements performed in pp and p-Pb collisions have recently revealed unexpected features not in line with the expectations based on previous measurements from $\rm{e^+e^-}$ and ep collisions, showing that charm fragmentation fractions are not universal. The investigation of initial-state effects such as shadowing in the collision of a proton with a heavy nucleus is also performed. Measurements of open heavy-flavour and quarkonia production in Pb-Pb collisions allow for testing the mechanisms of heavy-quark transport, energy loss, and coalescence effects during the hadronisation in the presence of a QCD medium. In this contribution, the most recent results on open heavy-flavour and quarkonia production in pp, p-Pb, and Pb-Pb collisions obtained by the ALICE Collaboration are discussed.

description: We obtain an explicit representation for quasiradial $γ$-harmonic functions, which shows that these functions have essentially algebraic nature. In particular, we give a complete description of all $γ$ which admit algebraic quasiradial solutions. Unlike the cases $γ=\infty$ and $γ=1$, only finitely many algebraic solutions is shown to exist for any fixed $|γ|>1$. Moreover, there is a special extremal series of $γ$ which exactly corresponds to the well-known ideal $m$-atomic gas adiabatic constant $γ=\frac{2m+3}{2m+1}$.

description: The Kubo-Greenwood equation, in combination with the first-principles Korringa-Kohn-Rostoker Coherent Potential Approximation (KKR-CPA) can be used to calculate the DC residual resistivity of random alloys at T = 0 K. We implemented this method in a multiple scattering theory based ab initio package, MuST, and applied it to the ab initio study of the residual resistivity of the high entropy alloy Al$_x$CoCrFeNi as a function of $x$. The calculated resistivities are compared with experimental data. We also predict the residual resistivity of refractory high entropy alloy MoNbTaV$_x$W. The calculated resistivity trends are also explained using theoretical arguments.

Nurses’ preferences for job-related outcomes
Creators: name: Chioccarello, Elisabetta
Publisher: name: University of British Columbia

description: This study investigates the preferences of nurses for professional and nonprofessional work-related outcomes, the professional/nonprofessional distinction arising from a theoretical framework developed by Kleingartner (1973). Using Kleingartner's distinction, various motivation theory concepts, and observations of nursing's professionalizing efforts, it was predicted that nurses would attach greater importance to professional work-related outcomes than to nonprofessional work-related outcomes. A questionnaire was developed and distributed to nurses in four different Lower Mainland hospitals. The results suggest that nurses do attach greater importance to professional than to nonprofessional work-related outcomes that this does not vary with employing hospital, and that individual work-related outcomes are rated in a very consistent and similar manner by nurses in different hospitals.
