description: We introduce a density tensor hierarchy for open system dynamics, that recovers information about fluctuations lost in passing to the reduced density matrix. For the case of fluctuations arising from a classical probability distribution, the hierarchy is formed from expectations of products of pure state density matrix elements, and can be compactly summarized by a simple generating function. For the case of quantum fluctuations arising when a quantum system interacts with a quantum environment in an overall pure state, the corresponding hierarchy is defined as the environmental trace of products of system matrix elements of the full density matrix. Only the lowest member of the quantum noise hierarchy is directly experimentally measurable. The unit trace and idempotence properties of the pure state density matrix imply descent relations for the tensor hierarchies, that relate the order $n$ tensor, under contraction of appropriate pairs of tensor indices, to the order $n-1$ tensor. As examples to illustrate the classical probability distribution formalism, we consider a quantum system evolving by Itô stochastic and by jump process Schrödinger equations. As examples to illustrate the corresponding trace formalism in the quantum fluctuation case, we consider collisional Brownian motion of an infinite mass Brownian particle, and the weak coupling Born-Markov master equation. In different specializations, the latter gives the hierarchies generalizing the quantum optical master equation and the Caldeira--Leggett master equation. As a further application of the density tensor, we contrast stochastic Schrödinger equations that reduce and that do not reduce the state vector, and discuss why a quantum system coupled to a quantum environment behaves like the latter.

description: Large-radius excitons in polar crystals are considered. It is shown that translation invariant description of excitons interacting with a phonon field leads to a nonzero contribution of phonons into the exciton ground state energy only in the case of weak or intermediate electron-phonon coupling. A conclusion is made that self-trapped excitons cannot exist in the limit of strong coupling. Peculiarities of the absorption and emission spectra of translation invariant excitons in a phonon field are discussed. Conditions when the hydrogen-like exciton model remains valid in the case of electron-phonon interaction are found.

Scalar self-force on eccentric geodesics in Schwarzschild spacetime: a time-domain computation

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We calculate the self-force acting on a particle with scalar charge moving on a generic geodesic around a Schwarzschild black hole. This calculation requires an accurate computation of the retarded scalar field produced by the moving charge; this is done numerically with the help of a fourth-order convergent finite-difference scheme formulated in the time domain. The calculation also requires a regularization procedure, because the retarded field is singular on the particle's world line; this is handled mode-by-mode via the mode-sum regularization scheme first introduced by Barack and Ori. This paper presents the numerical method, various numerical tests, and a sample of results for mildly eccentric orbits as well as ``zoom-whirl'' orbits.

title: Divine causality and human free choice : Domingo Báñez and the Controversy de Auxiliis

description: This dissertation considers the mystery of the relationship between human free choice and God by focusing on the Controversy de Auxiliis (1582-1607) and the thought of Domingo Báñez, O.P. (1528-1604) in particular. The dissertation comprises four chapters and a conclusion preceded by a preface and brief historical introduction. The preface introduces the issue to be explored and the motivations for exploring it before providing a general synopsis of the dissertation that is more detailed than the present abstract. The historical summary that follows introduces a theological debate that has become widely unfamiliar to contemporary theology, even while conceptually, that debate remains perennial. The four-chapter body that follows may be divided into two general parts: Broadly, chapters One and Two exposit Báñez’s thought, while chapters Three and Four critique it. Chapter One explores Báñez’s positive account of physical premotion, human freedom and sin. Chapter Two examines Báñez’s critique of Luis de Molina S.J.’s alternative proposal, in conjunction with some contemporary sources from both sides of the debate (Molina was Báñez’s principal adversary in the Controversy de Auxiliis). Báñez’s line of critique in Chapter Two is found to be cogent. Chapter Three investigates Molina’s critique of Báñez and finds it too to be cogent, even though Molina’s positive account was found to be problematic in Chapter Two. Chapter Four begins by exploring Bernard Lonergan S.J.’s work on divine causality and human free choice. Lonergan attempts to provide a fresh historical reading of Aquinas that is unencumbered by the presuppositions of the Controversy de Auxiliis. The first part of Chapter Four explains Lonergan’s critique of Báñez and finds it convincing, while the second part of the chapter finds Lonergan’s interpretation of Aquinas problematic from a theoretical standpoint. Chapter Four then offers a constructive critique of Lonergan’s interpretation before advancing an alternative way to think about God’s causation of human free choices. In closing, this dissertation argues that God creates human free choices, but that in creating a human free choice, God, or God’s creative will, is not an antecedent condition that determines choice. Rather, God creates the entire reality of a human free choice—both what it is and that it is—and in so doing, part of the reality God creates just is that choice’s being up to its human agent.

description: We present a map of the major part of the central molecular zone (CMZ) of simultaneous observations in the NH3 (J,K) = (1,1) and (2,2) lines using the Kagoshima 6-m telescope. The mapped area is -1.000 < l < 1.625 deg, -0.375 < b < +0.250 deg. The kinetic temperatures derived from the (2,2) to (1,1) intensity ratios are 20--80 K or exceed 80 K. The gases corresponding to temperature of 20--80 K and > 80 K contain 75% and 25% of the total NH3 flux, respectively. These temperatures indicate that the dense molecular gas in the CMZ is dominated by gas that is warmer than the majority of the dust present there. A comparison with the CO survey by Sawada et al. (2001) shows that the NH3 emitting region is surrounded by a high pressure region on the l-v plane. Although NH3 emission traces dense gas, it is not extended into a high pressure region. Therefore, the high pressure region is less dense and has to be hotter. This indicates that the molecular cloud complex in the Galactic center region has a ``core'' of dense and warm clouds which are traced by the NH3 emission, and an ``envelope'' of less dense and hotter gas clouds. Besides heating by ambipolar diffusion, the hot plasma gas emitting the X-ray emission may heat the hot ``envelope''.

The structures of 1 − 4 were unambiguously elucidated by comprehensive spectroscopic analyses. Abietane diterpenoids were isolated from the plant for the first time. All isolates were tested for their neuroprotective activities against H2O2-induced SH-SY5Y cells injury, and compound 2 showed moderate effect at the concentrations ranging from 5 ∼ 20 μM in vitro assay.
An SU(3) symmetry for light neutrinos

description: It is proposed that light neutrinos form a triplet in a global SU(3) symmetry in mass eigenstate basis. Assuming that the SU(3)symmetry is broken in the direction (-alambda_{3}+frac{b}/{sqrt{3}}lambda_{8}), and after going to the flavor basis we predict atmospheric mixing angle, sin ^{2}theta_{23}=0.5 and sin theta_{13}=0 if nu_{mu}-nu_{tau} symmetry is assumed. In the flavor basis the diagonal part of matrix coefficient of b (dominant part) is found to transform like (lambda_{3}+frac{1}/{sqrt{3}}lambda_{8}). Imposing the same on matrix coefficient of $a$ fixes solar mixing angle,sin ^{2}theta _{12}=frac{1}{3}. Implications for neutrinoless double beta-decay are discussed.

description: The nonlinear saturation of the r-mode instability and its effects on the spin evolution of Low Mass X-ray Binaries (LMXBs) are modeled using the triplet of modes at the lowest parametric instability threshold. We solve numerically the coupled equations for the three mode amplitudes in conjunction with the spin and temperature evolution equations. We observe that very quickly the mode amplitudes settle into quasi-stationary states. Once these states are reached, the mode amplitudes can be found algebraically and the system of equations is reduced from eight to two equations: spin and temperature evolution. Eventually, the system may reach thermal equilibrium and either (1) undergo a cyclic evolution with a frequency change of at most 10%, (2) evolve toward a full equilibrium state in which the accretion torque balances the gravitational radiation emission, or (3) enter a thermogravitational runaway on a very long timescale of about $10^6$ years. Alternatively, a faster thermal runaway (timescale of about 100 years) may occur. The sources of damping considered are shear viscosity, hyperon bulk viscosity and boundary layer viscosity. We vary proprieties of the star such as the hyperon superfluid transition temperature T_c, the fraction of the star that is above the threshold for direct URCA reactions, and slippage factor, and map the different scenarios we obtain to ranges of these parameters. For all our bound evolutions the r-mode amplitude remains small $\sim 10^{-5}$. The spin frequency is limited by boundary layer viscosity to $ν_{max} \sim 800 Hz [S_{ns}/(M_{1.4} R_6)]^{4/11} T_8^{-2/11}$. We find that for $ν> 700$ Hz the r-mode instability would be active for about 1 in 1000 LMXBs and that only the gravitational waves from LMXBs in the local group of galaxies could be detected by advanced LIGO interferometers.

Leptophilic Composite Asymmetric Dark Matter and its Detection

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a model which explains the baryon asymmetry of the universe and dark matter relic density at the same time. In this model, dark matter candidate is the dark baryon composed by dark quarks. A scalar mediator, which couples to the standard model leptons and dark quarks, is introduced to generate the asymmetry of baryon and dark baryon simultaneously. Direct detection and collider detection of this model are studied. We find that current underground direct detection experiments and LHC can hardly detect this model. But future lepton colliders, such as CEPC, have great potential to detect a large portion of the model parameter space by "displaced lepton jet" signal.

We find the exact expression of the capacity of entanglement which is valid for a finite dimension of the Hilbert space. We argue that in the gravitational path integral, the capacity of entanglement receives contributions only from the sub-leading saddle points corresponding to the partially connected geometries.

description: We present a quantum auction protocol using superpositions to represent bids and distributed search to identify the winner(s). Measuring the final quantum state gives the auction outcome while simultaneously destroying the superposition. Thus non-winning bids are never revealed. Participants can use entanglement to arrange for correlations among their bids, with the assurance that this entanglement is not observable by others. The protocol is useful for information hiding applications, such as partnership bidding with allocative externality or concerns about revealing bidding preferences. The protocol applies to a variety of auction types, e.g., first or second price, and to auctions involving either a single item or arbitrary bundles of items (i.e., combinatorial auctions). We analyze the game-theoretical behavior of the quantum protocol for the simple case of a sealed-bid quantum, and show how a suitably designed adiabatic search reduces the possibilities for bidders to game the auction. This design illustrates how incentive rather that computational constraints affect quantum algorithm choices.

description: The local spectroscopic signatures of metamagnetic criticality in Sr3Ru2O7 were explored using scanning tunneling microscopy (STM). Singular features in the tunneling spectrum were found close to the Fermi level, as would be expected in a Stoner picture of itinerant electron metamagnetism. These features showed a pronounced magnetic field dependence across the metamagnetic critical point, which cannot be understood in terms of a naive Stoner theory. In addition, a pseudo-gap structure was observed over several tens of meV, accompanied by a c(2x2) superstructure in STM images. This result represents a new electronic ordering at the surface in the absence of any measurable surface reconstruction.

description: The vector-tensor Horndeski theory is supplemented by a real, massless scalar field non-minimally coupled to the Horndeski interaction term. The generic dyonic Reissner-Nordstrom solutions characterized by electric and magnetic charges, acquire an instability and bifurcate into electromagnetically charged solutions presenting an horizon and a cloud of scalar hairs at specific values of the non-minimal coupling constant. These hairy black holes are studied in terms of the physical parameters of the model and the critical phenomena limiting their domain of existence are discussed.

Improved VLBI astrometry of OH maser stars

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Aims: Accurate distances to evolved stars with high mass loss rates are needed for studies of many of their fundamental properties. However, as these stars are heavily obscured and variable, optical and infrared astrometry is unable to provide enough accuracy. Methods: Astrometry using masers in the circumstellar envelopes can be used to overcome this problem. We have observed the OH masers of a number of Asymptotic Giant Branch (AGB) stars for approximately 1 year with the Very Long Baseline Array (VLBA). We have used the technique of phase referencing with in-beam calibrators to test the improvements this technique can provide to Very Long Baseline Interferometry (VLBI) OH maser astrometric observations. Results: We have significantly improved the parallax and proper motion measurements of the Mira variable stars U Her, S CrB and RR Aql. Conclusions: It is shown that both in-beam phase-referencing and a decrease in solar activity during the observations significantly improves the accuracy of the astrometric observations. The improved distances to S CrB (418 +21 -18 pc) and RR Aql (633 +214 -128 pc) are fully consistent with published P-L relations, but the distance to U Her (266 +32 -28 pc) is significantly smaller. We conclude that for sources that are bright and have a nearby in-beam calibrator, VLBI OH maser astrometry can be used to determine distances to OH masing stars of up to ~2 kpc.

Effects of hadronic loops on the direct CP violation of $B_{c}$

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: It is well known that the final state interaction plays an important role in the decays of $B$-meson. The contribution of the final state interaction which is supposed to be long-distance effects, to the concerned processes can interfere with that of the short-distance effects produced via the tree and/or loop diagrams at quark-gluon level. The interference may provide a source for the direct CP violation $\mathcal{A}_{CP}$ in the process $B_{c}^{+}\to D^{0}π^{+}$. We find that a typical value of $\mathcal{A}_{CP}$ when the final state interaction effect is taken into account can be about -22% which is different from that without the final state interaction effect. Therefore, when we extract information on CP violation from the data which will be available at LHCb and the new experiments in $B$-factories, the contribution from the final state interaction must be included. This study may be crucial for searching new physics in the future.

Interpersonal assessment of psychopathy
Creators: name: Foreman, Michael Ernest
Publisher: name: University of British Columbia
Year: 2012

description: This study was concerned with the relations between representations of psychopathy and interpersonal perceptions. From 147 inmates seen in a federal medium security prison, 79 of the men provided complete data for comparisons. Groups were defined under criteria from (1) the Psychopathy Checklist (PC) (Hare, 1985b), or (2) American Psychiatric Association (1980, 1987) outlines for Antisocial Personality Disorder (APD). Measures were derived from the Interpersonal Adjective Scales-Revised (IAS-R) (Wiggins, Trapnell, and Phillips, 1988 ) which relate interpersonally defined perceptions of personality as locations within a circumplex space--Interpersonal Circle (Wiggins, 1979, 1980). Self-ratings were obtained as descriptive of (1) self, (2) ideal self, (3) self as thought seen by a friends, and (4) self as thought seen by a specific member of the institutional staff. A rating was also obtained from the specific staff members as descriptive of the particular inmates. Comparisons were also made with respect to the specificity and sensitivity of MMPI profiles considered relevant to psychopathy. Supplementary comparisons used selected scales from the Adjective Checklist (ACL) (Gough and Heilbrun, 1980) and Rosenberg's (1965) Self- esteem Scale. These comparisons provided manipulation checks of the consistency of the data and contributed to the interpretive generalizability of the results. The primary hypotheses were that a group of individuals defined as psychopathic would show differences in representations obtained from self-rated and other-rated descriptions, with respect to circumplex location and derived difference scores from the IAS-R, in comparison to groups considered non-psychopathic. Results indicated differential perceptions, particularly by staff members, which provided good discriminations of groups based on the PC but not for groups defined by APD. Circumplex locations of psychopaths defined by the PC were consistent with expectations for the Interpersonal Circle. The discriminative utility of group differences was much higher for the PC-defined groups than for APD relative to the base rates for these different categorizations. The results are discussed in terms of (1) their contribution to the nomological network for the concept of psychopathy as represented by the PC, (2) specific limitations of the study, and (3) the evident confusion which can result from the use of measures assumed to to relate to the 'psychopath,' but that rely on primarily behavioural descriptions.

description: We present a general numerical scheme for the practical implementation of statistical moment closures suitable for modeling complex, large-scale, nonlinear systems. Building on recently developed equation-free methods, this approach numerically integrates the closure dynamics, the equations of which may not even be available in closed form. Although closure dynamics introduce statistical assumptions of unknown validity, they can have significant computational advantages as they typically have fewer degrees of freedom and may be much less stiff than the original detailed model. The closure method can in principle be applied to a wide class of nonlinear problems, including strongly-coupled systems (either deterministic or stochastic) for which there may be no scale separation. We demonstrate the equation-free approach for implementing entropy-based Eyink-Levermore closures on a nonlinear stochastic partial differential equation.

description: We study the dependence of Ly$α$ escape from galaxies on UV continuum size and luminosity using a sample of 40 Green Pea (GP) galaxies, which are the best local analogs of high-redshift Ly$α$-emitters (LAEs). We use the Cosmic Origins Spectrograph near-ultraviolet images from the \textit{Hubble Space Telescope} to measure the UV size and luminosity with $0.047''$ spatial resolution. Like most galaxies the GPs show a log-normal size distribution. They also show a positive correlation between size and UV-continuum luminosity. The slope of the size-continuum luminosity relation for GPs is consistent with those of continuum-selected star-forming galaxies at low and high redshifts. A distinctive feature of GPs is a very compact typical radius of 0.33 kpc with a population spread (1$σ$) of 0.19 kpc. The peak of the size distribution and the intercept of the size-luminosity relation of GPs are noticeably smaller than those of continuum-selected star-forming galaxies at similar redshifts. There are statistically significant anti-correlations found between the circularized half-light radius ($r_{\rm cir,50}$), the Ly$α$ equivalent width (EW(Ly$α$)), and the Ly$α$ escape faction ($f^{Lyα}_{esc}$), suggesting that small UV-continuum radii are crucial for Ly$α$ emission. GPs and high-redshift LAEs have similar sizes, once spatial resolution effects are properly considered. Our results show that a compact/small size is crucial for escape of Ly$α$ photons, and that Ly$α$-emitters show constant characteristic size independent of their redshift.

Disorder lines, modulation, and partition function zeros in free fermion models

Publisher: name: arXiv

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

description: The modulation is analyzed from the analytical properties of zeros of free fermionic partition function on the complex plane of wave numbers. It is shown how these properties are related to the oscillations of correlation functions. This approach can be used for analysis of phase transitions with local or nonlocal order parameters, as well as for the disorder lines. We find an infinite cascade of disorder lines at finite temperature in the quantum $XY$ chain (equivalent to free fermions). The well-known ground state factorization on the disorder line, and consequently, disentanglement, is shown to follow directly from analytical properties of this model on the complex plane. From the quantum-classical correspondence the results for the chain are used to detect the disorder lines in several frustrated 2D Ising models. The present formalism can be applied to other fermionic models in two and three spatial dimensions. In particular, we find the temperature-dependent Fermi wave vector of oscillations in the degenerate gas of 3D fermions, which naturally leads in the limit $T \to 0$ to the definition of the Fermi energy as the surface of quantum criticality. The modulation is a very common phenomenon, and it occurs in a large variety of models. The important point is that all these modulation transitions can be related to the complex zeros of partition functions, as done in the present study.

description: It has been shown that a decentralized relay selection protocol based on opportunistic feedback from the relays yields good throughput performance in dense wireless networks. This selection strategy supports a hybrid-ARQ transmission approach where relays forward parity information to the destination in the event of a decoding error. Such an approach, however, suffers a loss compared to centralized strategies that select relays with the best channel gain to the destination. This paper closes the performance gap by adding another level of channel feedback to the decentralized relay selection problem. It is demonstrated that only one additional bit of feedback is necessary for good throughput performance. The performance impact of varying key parameters such as the number of relays and the channel feedback threshold is discussed. An accompanying bit error rate analysis demonstrates the importance of relay selection.

description: This paper introduces a model that identifies spatial relationships for a structural analysis based on the concept of simplicial complex. The spatial relationships are identified through overlapping two map layers, namely a primary layer and a contextual layer. The identified spatial relationships are represented as a simplical complex, in which simplices and vertices respectively represent two layers of objects. The model relies on the simplical complex for structural representation and analysis. To quantify structural properties of individual primary objects (or equivalently simplices), and the simplicial complex as a whole, we define a set of centrality measures by considering multidimensional chains of connectivity, i.e. the number of contextual objects shared by a pair of primary objects. With the model, the interaction and relationships with a geographic system are modeled from both local and global perspectives. The structural properties and modeling capabilities are illustrated with a simple example and a case study applied to the structural analysis of an urban system.

The relationship between personality type and parenting style
Creators: name: Reed, Lori Patricia
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the relationship of personality type and parenting style. Using a sample of convenience, 102 parents (71 female, 31 male) completed three tests: the Myers Briggs Type Indicator which measures personality types, 64 items from the Block Child Rearing Practices Report which measures parental child rearing attitudes and values, and FACES III which measures family functioning. Forty of the 64 items from the Block Child Rearing Practices Report clustered into two homogeneous groups that served as subtests for parenting style. A canonical correlation between four personality type scores (extraversion-introversion, sensing—intuition, thinking—feeling, judging— perceiving) and two parenting style scores (nurturance, restrictiveness) indicated significant relationships between personality and parenting. Parents who were strong on sensing and moderately introverted tended to employ a parenting style that was highly restrictive and moderately nurturant. Parents who were strong on perceiving and moderately extraverted tended to employ a parenting style that was highly nurturing and much less restrictive.

description: We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog contains 77,429 objects; this is an increase of over 30,000 entries since the previous edition. The catalog consists of the objects in the SDSS Fifth Data Release that have luminosities larger than M_i = -22.0 (in a cosmology with H_0 = 70 km/s/Mpc, Omega_M = 0.3, and Omega_Lambda = 0.7) have at least one emission line with FWHM larger than 1000 km/s, or have interesting/complex absorption features, are fainter than i=15.0, and have highly reliable redshifts. The area covered by the catalog is 5740 sq. deg. The quasar redshifts range from 0.08 to 5.41, with a median value of 1.48; the catalog includes 891 quasars at redshifts greater than four, of which 36 are at redshifts greater than five. Approximately half of the catalog quasars have i < 19; nearly all have i < 21. For each object the catalog presents positions accurate to better than 0.2 arcsec. rms per coordinate, five-band (ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains basic radio, near-infrared, and X-ray emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3800--9200A at a spectral resolution of ~2000. The spectra can be retrieved from the public database using the information provided in the catalog. The average SDSS colors of quasars as a function of redshift, derived from the catalog entries, are presented in tabular form. Approximately 96% of the objects in the catalog were discovered by the SDSS.

B-type defects in Landau-Ginzburg models
Creators: name: Brunner, Ilka
name: Roggenkamp, Daniel
Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider Landau-Ginzburg models with possibly different superpotentials glued together along one-dimensional defect lines. Defects preserving B-type supersymmetry can be represented by matrix factorisations of the difference of the superpotentials. The composition of these defects and their action on B-type boundary conditions is described in this framework. The cases of Landau-Ginzburg models with superpotential W=X^d and W=X^d+Z^2 are analysed in detail, and the results are compared to the CFT treatment of defects in N=2 superconformal minimal models to which these Landau-Ginzburg models flow in the IR.

description: I present a set of remarks related to joint works \cite{paper1},\cite{paper2},\cite{paper3},\cite{MMNO}. These are remarks about polynomials solutions and vertex operators, eigenproblem for polynomials and a remark related to the the conjecture of Alexandrov and Mironov, Morozov about the ratios of the projective Schur functions. New results on the bilinear relations between characters of the symmetric and of the Sergeev group and on bilinear relations between skew Schur and projective Schur functions and also between shifted Schur and projective Schur functions are added. Certain new matrix models are considered and a comment on Mironov-Morozov-Natanzon cut-and-join relation is added.

description: This study ascertained the effect of multiple taxations on sustainability in Juhel pharmaceutical company Awka, Anambra State, using taxes and levies as the independent variables while triple bottom line was used for dependent variable. Survey research design was adopted. Data were generated form the questionnaires administered to the respondents. Multiple regression analysis was employed to test the hypotheses. The result revealed that taxes have negative effect on sustainability of Juhel manufacturing company; levies have positive and significant effect on sustainability in Juhel manufacturing company in the State. Based on the findings of this study, it is concluded that multiple taxation significantly affects the sustainability in Juhel manufacturing Company in Anambra state, based on the findings; it was recommended among others that various levies and taxes should be harmonized to enhance efficiency. Federal, state and local governments should take collaborative steps in eliminating multiple taxations in Nigeria
Natural Night Sky Brightness during Solar Minimum

description: In 2018, Solar Cycle 24 entered into a solar minimum phase. During this period, 11 million zenithal night sky brightness (NSB) data were collected at different dark sites around the planet, including astronomical observatories and natural protected areas, with identical broadband Telescope Encoder and Sky Sensor photometers (based on the Unihedron Sky Quality Meter TSL237 sensor). A detailed observational review of the multiple effects that contribute to the NSB measurement has been conducted with optimal filters designed to avoid brightening effects by the Sun, the Moon, clouds, and other astronomical sources (the Galaxy and zodiacal light). The natural NSB has been calculated from the percentiles for 44 different photometers by applying these new filters. The pristine night sky was measured to change with an amplitude of 0.1 mag/arcsec$^2$ in all the photometers, which is suggested to be due to NSB variations on scales of up to months and to be compatible with semiannual oscillations. We report the systematic observation of short-time variations in NSB on the vast majority of the nights and find these to be related to airglow events forming above the mesosphere.

On an implementation of abstract interpretation
Creators: name: Westcott, Doug
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes an implementation of abstract interpretation and its application to strictness analysis and termination analysis. The abstract interpretation is performed based on a lattice-theoretical model of abstraction, or translation, of functions expressed in a lambda-calculus notation and defined over a concrete domain into functions defined over a user-specified, application-dependent, abstract domain. The functions thus obtained are then analyzed in order to find their least fixed-points in the lattice which is the abstract domain, using a method which is a simplification of the frontiers algorithm of Chris Clack and Simon Peyton Jones. In order to achieve the required efficiency, this method is implemented using lattice annotation, along with constraints upon the annotations. The implementation is then applied to the problems of strictness analysis and termination analysis, deriving useful pre-compilation information for many functions. The concrete domains over which the functions are defined may or may not include lists.

description: Dans notre travail de Bachelor, nous avons voulu répondre à la question de recherche suivante : Qu’est-ce qui favorise une intégration sociale des élèves allophones en classe régulière ? ainsi qu’une sous-question : Quels sont les facilitateurs et les freins ? Tout d’abord, nous avons abordé des notions théoriques en lien avec l’intégration, le sentiment d’appartenance et le rôle des camarades. Nous avons relevé l’importance des interactions entre individus pour favoriser l’intégration de l’élève primo-arrivant ainsi que la participation de celui-ci à la vie de la classe pour qu’il puisse développer un sentiment d’appartenance. Nous également relevé qu’il est important pour l’élève de garder les valeurs de sa propre culture. L’école y joue un rôle très important, car elle doit proposer des structures pédagogiques adéquates aux élèves allophones. Pour pouvoir répondre à notre question, nous nous sommes entretenues avec huit participants dont quatre élèves et quatre étudiantes de la HEP. Il en ressort que pour une intégration sociale réussie, les élèves doivent se sentir appartenir au groupe, doivent interagir avec le groupe classe, pour ainsi s’habituer aux coutumes de la classe. Pour y parvenir, les camarades y jouent un rôle crucial, car c’est principalement grâce à eux que les élèves peuvent s’intégrer socialement. En outre, il en ressort également que les enseignants ont un rôle important dans l’intégration de ces élèves et doivent mettre en place des activités adéquates afin de favoriser leur participation.
