description: Recent experimental advances have reignited theoretical interests in heavy-flavor hadrons. In this work, we study the magnetic moments of the spin-1/2 singly charmed baryons up to the next-to-leading order in covariant baryon chiral perturbation theory with the extended-on-mass-shell renormalization scheme. The pertinent low energy constants $g_{1-4}$ are fixed with the help of the quark model and the heavy quark spin flavor symmetry, while the remaining $d_2$, $d_3$, $d_5$ and $d_6$ are determined by fitting to the lattice QCD pion-mass dependent data. We study the magnetic moments as a function of $m_π^2$ and compare our results with those obtained in the heavy baryon chiral perturbation theory. We find that the loop corrections induced by the anti-triplet states are dominated by the baryon pole diagram. In addition, we predict the magnetic moments of the spin-1/2 singly charmed baryons and compare them with those of other approaches.

description: We have obtained FUV spectra of two clusters of galaxies with FUSE, the Far Ultraviolet Spectroscopic Explorer. The Coma cluster was observed for a total of 28.6 ksec, the Virgo cluster for 10.9 ksec. Neither spectrum shows significant O VI (1032, 1038 A) emission at the cluster redshift. Such emission would be expected from the warm [(5-10) x 10^5 K] component of the intracluster medium that has been proposed to explain the excess EUV and SXR flux present in EUVE and ROSAT observations of these clusters. Our 2-sigma upper limits on the O VI 1032 A flux from Coma and Virgo exclude all published warm-gas models of the EUV excess in these clusters.

description: The binary perceptron is the simplest artificial neural network formed by $N$ input units and one output unit, with the neural states and the synaptic weights all restricted to $\pm 1$ values. The task in the teacher--student scenario is to infer the hidden weight vector by training on a set of labeled patterns. Previous efforts on the passive learning mode have shown that learning from independent random patterns is quite inefficient. Here we consider the active online learning mode in which the student designs every new Ising training pattern. We demonstrate that it is mathematically possible to achieve perfect (error-free) inference using only $N$ designed training patterns, but this is computationally unfeasible for large systems. We then investigate two Bayesian statistical designing protocols, which require $2.3 N$ and $1.9 N$ training patterns, respectively, to achieve error-free inference. If the training patterns are instead designed through deductive reasoning, perfect inference is achieved using $N\!+\!\log_{2}\!N$ samples. The performance gap between Bayesian and deductive designing strategies may be shortened in future work by taking into account the possibility of ergodicity breaking in the version space of the binary perceptron.

Η πρώτη υλοποιήθηκε το 1993, ενώ η δεύτερη ολοκληρώθηκε το 2001. Από το 2001 μέχρι σήμερα έχουν τεθεί διάφορα ζητήματα που αφορούν τη σχέση του επισκέπτη/χρήστη με το πάρκο. Στόχος της προτεινόμενης επέμβασης είναι η αποσαφήνιση του χαρακτήρα των περιοχών πάνω στο όριο του Πάρκου, η επεξεργασία του περιγράμματος του Πάρκου και τέλος η ανάπτυξη και η αξιοποίηση των λειτουργικών χαρακτηριστικών των περιοχών έτσι όπως έχουν διαμορφωθεί κατά τον χρόνο λειτουργίας του από τους χρήστες ανεξάρτητα από τον αρχικό σχεδιασμό. Η επέμβαση έχει επίσης ως στόχο μέσα από την ανάδειξη της κάθε περιοχής, να δημιουργήσει έναν μεγάλο πλούτο εικόνων στον επισκέπτη.
description: The Park Environmental Awareness Anthony Tritsis is a green area of hypertopical importance designed in two stages. The first stage was completed in 1993 and the second one in 2001. From 2001 until today many issues have been raised regarding the relationship of the visitor/user with the park. The goal of the proposed intervention is to clarify park’s character on its boundaries, elaborate its outline, develop and make the best of areas’ functional features as formed during its operation by the users, regardless of the initial design. Intervention also aims to create plenty images to the visitor bringing into prominence every single area of the park.

Publisher: name: Bank of Canada
Year: 2014

description: This paper examines the impact of product market competition and corporate governance on the cost of debt financing and the use of bond covenants. We find that more anti-takeover provisions are associated with a lower cost of debt only in competitive industries. Because they are exposed to higher takeover risk in competitive industries, bondholders charge higher bond spreads to firms that have fewer anti-takeover provisions. Once firms’ anti-takeover provisions are in place, we find that bondholders use fewer payment and debt priority covenants in competitive industries. Our results suggest that product market competition plays a crucial role in explaining the way a firm’s anti-takeover protection affects the cost of debt and the use of bond covenants.
description: Les auteurs examinent l’incidence de la concurrence sur le marché des produits, et de la gouvernance d’entreprise sur le coût du financement par emprunt d’une part, et sur l’inclusion de clauses restrictives dans les contrats obligataires d’autre part. Ils constatent que l’existence de défenses anti-offre publique d’achat (OPA) en nombre accru est associée à un coût d’emprunt inférieur, mais seulement dans les secteurs où la concurrence est vive. Étant donné que, dans ces secteurs, les porteurs d’obligations sont exposés à un plus grand risque d’OPA, ils imposent des taux de rendement obligataire supérieurs aux firmes moins bien protégées contre ce type d’offres. Lorsque des défenses anti-OPA sont en place, les auteurs observent que, dans les secteurs à forte concurrence, les porteurs d’obligations recourent moins aux clauses restrictives à l’égard des paiements et de la priorité des créances. Les résultats de l’étude donnent à penser que la concurrence sur le marché des produits joue un rôle essentiel pour expliquer l’effet des dispositifs anti-OPA sur le coût des capitaux empruntés et l’ajout de clauses restrictives aux contrats obligataires.

description: We propose an integrable model of one-dimensional (1D) interacting electrons coupled with the local orbitals arrayed periodically in the chain. Since the local orbitals are introduced in a way that double occupation is forbidden, the model keeps the main feature of the periodic Anderson model with an interacting host. For the attractive interaction, it is found that the local orbitals enhance the effective mass of the Cooper-pair-like singlets and also the pair correlation in the ground state. However, the persistent current is depressed in this case. For the repulsive interaction case, the Hamiltonian is non-Hermitian but allows Cooper pair solutions with small momenta, which are induced by the hybridization between the extended state and the local orbitals.

description: We use surface brightness fluctuation (SBF) measurements to constrain the distance to low surface brightness (LSB) dwarfs in the vicinity of M101. Recent work has discovered many LSB candidate satellite companions of M101. However, without accurate distances, it is problematic to identify these dwarfs as physical satellites of M101. We use CFHT Legacy Survey (CFHTLS) data to measure the SBF signal for 43 candidate dwarfs. The data is deep enough that we constrain 29 of these to be unassociated background galaxies by their lack of SBF. We measure high S/N SBF signals for two of the candidate dwarfs, which are consistent with being at the distance of M101. The remaining candidates are too LSB and/or small for their distances to be constrained. Still, by comparison with Local Group dwarfs, we argue that the M101 satellite system is likely now complete down to stellar masses of $\sim5\times10^5$ M$_\odot$. We also provide a new SBF distance for the nearby dwarf UGC 8882, which suggests that it is significantly outside of the virial radius of M101 and is thus not a physical satellite. By constraining the distances to a majority of the candidates using only archival data, our work demonstrates the usefulness of SBF for nearby LSB galaxies and for studying the satellite systems of nearby massive galaxies.

description: We describe the results of a search for time variability of the fine structure constant, alpha, using absorption systems in the spectra of distant quasars. Three large optical datasets and two 21cm/mm absorption systems provide four independent samples, spanning 23% to 87% of the age of the universe. Each sample yields a smaller alpha in the past and the optical sample shows a 4-sigma deviation: da/a = -0.72 +/- 0.18 x 10^{-5} over the redshift range 0.5 < z < 3.5. We find no systematic effects which can explain our results. The only potentially significant systematic effects push da/a towards positive values, i.e. our results would become more significant were we to correct for them.

title: Technology Shocks, Labour Mobility and Aggregate Fluctuations
Creators: name: Hauser, Daniela
Publisher: name: Bank of Canada
Year: 2014

description: We provide evidence regarding the dynamic behaviour of net labour flows across U.S. states in response to a positive technology shock. Technology shocks are identified as disturbances that increase relative state productivity in the long run for 226 state pairs, encompassing 80 per cent of labour flows across U.S. states in the 1976 - 2008 period. The data suggest heterogeneous responses of both employment and net labour flows across states, conditional on a positive technology shock. We build a two-region dynamic stochastic general equilibrium (DSGE) model with endogenous labour mobility and region-specific shocks to account for this evidence. We calibrate the model economy consistently with the observed differences in the degree of nominal rigidities across states, and show that we replicate the different patterns of the responses in employment and net labour flows across states following a technology shock.
description: Nous analysons le comportement dynamique des flux nets de main-d’oeuvre aux États-Unis induit par un choc technologique positif. Dans notre étude, les chocs technologiques désignent des perturbations menant à une hausse à long terme de la productivité relative dans un État, eu égard à un ensemble de 226 paires d’États qui rendent compte de 80 % des flux de main-d’oeuvre enregistrés à l’intérieur des frontières américaines de 1976 à 2008. Selon les données utilisées, un choc technologique positif suscite des réactions hétérogènes en ce qui concerne l’emploi et les flux nets de main-d’oeuvre interétatiques. Pour refléter cette observation, nous construisons un modèle d’équilibre général dynamique et stochastique à deux régions où la mobilité des travailleurs est endogène et les chocs ont une spécificité régionale. Nous étalonnons ce modèle en tenant pleinement compte des écarts relevés dans les niveaux de rigidité nominale entre États. Nous montrons que le modèle reproduit les divers types de réactions de l’emploi et des flux nets de main-d’oeuvre causées par un choc technologique.

description: Recent experiments show the spontaneous breaking of rotational symmetry in the superconducting topological insulators M$_{x}$Bi$_{2}$Se$_{3}$ (M represents Cu, Sr, or Nd), suggesting that the pairing belongs to a two-dimensional representation of the $D_{3d}$ symmetry group of the crystal. Motivated by these progresses, we construct an exhaustive list of possible two-component pairings of the M$_{x}$Bi$_{2}$Se$_{3}$ superconductors, both for the odd-parity $E_{u}$ representation and for the even-parity $E_{g}$ representation. Starting from a tight-binding model for the normal phase of Bi$_{2}$Se$_{3}$ and M$_{x}$Bi$_{2}$Se$_{3}$, we firstly construct the pairing channels in the spin-orbital basis, up to second-nearest-neighbor pairing correlations in the basal plane. We then infer the properties of these pairings by transforming them to the band (pseudospin) basis for the conduction band. A comparison with the key experimental consensuses on M$_{x}$Bi$_{2}$Se$_{3}$ superconductors shows that the true pairings should also be multichannel. Besides a nematic and time-reversal symmetric pairing combination, the other pairings that we have identified are chiral and nematic at the same time, which may be nonunitary and have a spontaneous magnetization. A complementary set of experiments are proposed to identify the true pairing symmetries of these superconductors and their evolution with the doping concentration $x$.

description: A general half-plane contact problem in which the geometry is specified in a piecewise-quadratic sense over three segments is solved in closed form. This includes the effects of a moment applied sufficient to introduce separation of one segment and the application of a shearing force sufficient or insufficient to cause sliding. Extending existing solutions to asymmetrical problems is necessary in order to broaden our understanding of the behaviour of dovetail roots of gas turbine fan blades. In previous studies symmetrical contacts have often been used to represent a dovetail flank contact. In the asymmetrical case, the contact pressure may be considerably higher at one of the contact edges compared to the corresponding symmetrical case. Exploiting the generality provided with the solution presented in this study, several simpler indenter problems are investigated making use of an algebraic manipulator. The Mathematica code is made available for download.

description: Coherent excitation of materials via ultrafast laser pulses can have interesting, observable dynamics in time-resolved photoemission measurements. The broad spectral width of ultrafast pump pulses can coherently excite multiple exciton energy levels. When such coherently excited states are probed by means of photoemission spectroscopy, interference between the polarization of different exciton levels can lead to observable coherent exciton beats. Here, we present the theoretical formalism for evaluating the Time- and Angle- Resolved Photoemission Spectra (tr-ARPES) arising from the coherently excited exciton states. We subsequently apply our formalism to a simple model example of hydrogenic exciton energy levels to identify the dependencies that control the quantum beats. Our findings indicate that the most pronounced effect of coherent quantum excitonic beats is seen midway between the excited exciton energy levels and the central energy of the pump pulse provides tunability of this effect.

Decay of cosmological constant as Bose condensate evaporation

description: We consider the process of decay of symmetric vacuum state as evaporation of a Bose condensate of physical Higgs particles, defined over asymmetric vacuum state. Energy density of their selfinteraction is identified with cosmological constant $Λ$ in the Einstein equation. $Λ$ decay then provides dynamical realization of spontaneous symmetry breaking. The effective mechanism is found for damping of coherent oscillations of a scalar field, leading to slow evaporation regime as the effective mechanism for $Λ$ decay responsible for inflation without special fine-tuning of the microphysical parameters. This mechanism is able to incorporate reheating, generation of proper primordial fluctuations, and nonzero cosmological constant today.

description: We study the two-dimensional Potts model on the square lattice in the presence of quenched random-bond impurities. For q>4 the first-order transitions of the pure model are softened due to the impurities, and we determine the resulting universality classes by combining transfer matrix data with conformal invariance. The magnetic exponent beta/nu varies continuously with q, assuming non-Ising values for q>4, whereas the correlation length exponent nu is numerically consistent with unity. We present evidence for the correctness of a formerly proposed phase diagram, unifying pure, percolative and non-trivial random behaviour.

description: Polaritons in metals, semimetals, semiconductors, and polar insulators, with their extreme confinement of electromagnetic energy, provide many promising opportunities for enhancing typically weak light-matter interactions such as multipolar radiation, multiphoton spontaneous emission, Raman scattering, and material nonlinearities. These highly confined polaritons are quasi-electrostatic in nature, with most of their energy residing in the electric field. As a result, these "electric" polaritons are far from optimized for enhancing emission of a magnetic nature, such as spin relaxation, which is typically many orders of magnitude slower than corresponding electric decays. Here, we propose using surface magnon polaritons in negative magnetic permeability materials such as MnF$_2$ and FeF$_2$ to strongly enhance spin-relaxation in nearby emitters in the THz spectral range. We find that these magnetic polaritons in 100 nm thin-films can be confined to lengths over 10,000 times smaller than the wavelength of a photon at the same frequency, allowing for a surprising twelve orders of magnitude enhancement in magnetic dipole transitions. This takes THz spin-flip transitions, which normally occur at timescales on the order of a year, and forces them to occur at sub-ms timescales. Our results suggest an interesting platform for polaritonics at THz frequencies, and more broadly, a new way to use polaritons to control light-matter interactions.
THE IMPORTANCE AND PERFORMANCE OF TESTS FOR THE SELECTION OF INSTRUMENTAL VARIABLES

description: In this paper it is demonstrated that testing models for misspecification by OLS-based variable addition may lead to the acceptance of reduced form equations or other hybrid relationships derived from the structural form. The awkward result is obtained that in order to acquire consistent estimates of structural parameters some regressors that appear as significant are sometimes better removed from the specification. This illustrates the need for tests on the validity of exogeneity assumptions. From application of the variable addition approach to a single linear simultaneous regression model three basic types of tests for instrument adequacy are developped, viz. tests for exogeneity of the maintained instruments, for exogeneity of excluded regressors, and for exogeneity of included regressors. Finally it is shown Which ordenings of these tests and tests on the adequacy of the specification will lead to asymptotic independence of the test statistics. Such ordenings enable to exercise control over the overall type I error probability in a comprehensive model selection procedure.
Second magnetization peak in flux lattices: the decoupling scenario

Publisher: name: arXiv
Year: 1999
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The second peak phenomena of flux lattices in layered superconductors is described in terms of a disorder induced layer decoupling transition. For weak disorder the tilt mudulus undergoes an apparent discontinuity which leads to an enhanced critical current and reduced domain size in the decoupled phase. The Josephson plasma frequency is reduced by decoupling and by Josephson glass pinning; in the liquid phase it varies as 1/[BT(T+T_0)] where T is temperature, B is field and T_0 is the disorder dependent temperature of the multicritical point.

title: Search-for-Yield in Canadian Fixed-Income Mutual Funds and Monetary Policy
Creators: name: Gungor, Sermin

Publisher: name: Bank of Canada
Year: 2014

description: This paper investigates the effects of monetary policy on the risk-taking behavior of fixed-income mutual funds in Canada. We consider different measures of the stance of monetary policy and investigate active variation in mutual funds’ risk exposure in response to monetary policy. We find evidence in support of a systematic link between monetary conditions and intertemporal variation in the risk-taking behavior of mutual funds. Specifically, following an expansionary monetary shift, funds actively increase default-risk exposure (i.e., search-for-yield). This is particularly evident in the post-crisis period where interest rates were kept low for a prolonged period of time.
description: Les auteurs étudient l’incidence de la politique monétaire sur le comportement de prise de risques affiché au Canada par les gestionnaires de fonds communs de placement à revenu fixe. Pour ce faire, ils emploient différentes mesures de l’orientation de la politique monétaire et analysent les changements que ces gestionnaires apportent activement au niveau d’exposition au risque de leurs fonds, en fonction de la politique monétaire mise en oeuvre. Les résultats qu’ils obtiennent plaident pour l’existence d’un lien de nature systématique entre les conditions monétaires et la variation dans le temps du comportement de prise de risques adopté par les gestionnaires de fonds. En l’occurrence, lorsque la politique monétaire se fait expansionniste, ces derniers accroissent activement le niveau d’exposition au risque de défaillance des fonds qu’ils gèrent (c’est-à-dire qu’ils se tournent vers des placements plus risqués en vue d’obtenir de meilleurs rendements). Ce phénomène est particulièrement manifeste en ce qui concerne la période qui a suivi la crise récente, dans laquelle les taux d’intérêt ont été maintenus à de bas niveaux pendant longtemps.
Line-of-sight gas sloshing in the cool core of Abell 907

description: We present line-of-sight gas sloshing first found in a cool core in a galaxy cluster. The galaxy cluster Abell 907 is identified as a relaxed cluster owing to its global X-ray surface brightness taken by the Chandra X-ray Observatory. The X-ray residual image after removing the global emission of the intracluster medium (ICM), however, shows an arc-like positive excess and a negative excess surrounding the central positive excess in the cluster core, which in turn indicates a disturbance of the ICM. We analyze the X-ray spectra extracted from both regions and find that (1) the ICM temperature and the metal abundance in the positive excess are lower and higher than those in the negative excess, respectively, and (2) the ICM is nearly in pressure equilibrium. We also find a slight redshift difference between the positive and the negative excesses, which corresponds to the velocity shear of $1680^{+1300}_{-920}$ km s$^{-1}$ ($1σ$). The X-ray residual image and the ICM properties are consistent with those expected by line-of-sight gas sloshing. Assuming that the gas is moving toward inverse-parallel to each other along the line-of-sight, the shear velocity is expected to be $\sim 800$ km s$^{-1}$. The velocity field of this level is able to provide non-thermal pressure support by $\sim 34\%$ relative to the thermal one. The total kinetic energy inferred from the shear velocity corresponds to $\sim 30\%$ of the bolometric luminosity of the sloshing ICM. Abell 907 is therefore complementary to galaxy clusters in which gas sloshing takes place in the plane of the sky, and is important for understanding gas dynamics driven by sloshing and its influence on the heating to prevent runaway cooling.

description: While the red pigmentation in most flowering plants is due to the presence of anthocyanins, some species in the order Caryophyllales synthesize betalains instead. Betalains are derived from tyrosine and range from yellow (betaxanthins) to red-violet (betacyanins). The betalain biosynthetic pathway involves three enzymatic processes. (1) First, tyrosine is converted to L-DOPA. This dissertation characterizes the thrice-redundant cytochrome P450 (CYP450) genes that encode the enzymes responsible for this step and elucidates their likely evolutionary history. (2) Next, L-DOPA can be converted to betalamic acid (BA) by a 4,5-DOPA dioxygenase (DODA) enzyme. BA spontaneously condenses with amines or amino acids to yield yellow betaxanthins. Through site-directed mutagenesis and expression in yeast, this dissertation identifies the amino acid residues in DODAs that are required for this key enzymatic step. (3) Alternatively, L-DOPA molecules can be processed by a CYP450, resulting in cyclo-DOPA, which spontaneously reacts with BA to form red betacyanins. Mutagenesis and overexpression in plants and yeast demonstrate the divergent functionality between members of the CYP450 clades. The work herein also describes the search for these biosynthetic genes—DODAs and CYP450s—in the species Basella alba, better known as Malabar spinach. Comparative transcriptome analysis of red and white B. alba varieties yielded the betalain biosynthetic genes, which were then functionally characterized in yeast, beets, and Arabidopsis. Taken together, this dissertation advances our understanding of the evolution of the betalain biosynthetic network and contributes significant findings that enable future studies into this unique area of plant molecular biology

description: The end result of major sporting events has been shown to affect next-day stock returns through shifts in investor mood. By studying the soccer matches that led to the elimination of France and Italy from the 2010 FIFA World Cup, we show that mood-related pricing effects can materialize as sporting events unfold. We do this by using intraday stock prices for a firm cross-listed on the Paris and Milan stock exchanges. This strategy allows for a straightforward identification of pricing effects. During the soccer matches, stock prices in the country that eventually loses are lower by up to seven basis points. The probability of underpricing increases as elimination from the tournament becomes more likely.
description: Il a été démontré que les résultats de grandes compétitions sportives obtenus un certain jour ont une incidence sur les rendements boursiers du lendemain, à cause des changements d’humeur des investisseurs. En étudiant les matches qui ont conduit à l’élimination de la France et de l’Italie de la Coupe du monde de football de 2010, les auteurs montrent que les changements d’humeur des investisseurs peuvent influer sur les cours au fil même des compétitions. Pour ce faire, ils exploitent les prix intrajournaliers des actions d’une entreprise cotée à la fois à la Bourse de Paris et à celle de Milan. Cette stratégie permet de repérer facilement les effets sur les prix. Pendant les matches, les cours de l’action étudiée peuvent être jusqu’à sept points de base en retrait dans le pays qui est sur le point de perdre. La probabilité de sous-évaluation augmente en même temps que se profile l’élimination de l’équipe nationale du tournoi.
Dynamics of Chainlike Molecules on Surfaces

description: We consider the diffusion and spreading of chainlike molecules on solid surfaces. We first show that the steep spherical cap shape density profiles, observed in some submonolayer experiments on spreading polymer films, imply that the collective diffusion coefficient $D_C(θ)$ must be an increasing function of the surface coverage $θ$ for small and intermediate coverages. Through simulations of a discrete model of interacting chainlike molecules, we demonstrate that this is caused by an entropy-induced repulsive interaction. Excellent agreement is found between experimental and numerically obtained density profiles in this case, demonstrating that steep submonolayer film edges naturally arise due to the diffusive properties of chainlike molecules. When the entropic repulsion dominates over interchain attractions, $D_C(θ)$ first increases as a function of $θ$ but then eventually approaches zero for $θ\to 1$. The maximum value of $D_C(θ)$ decreases for increasing attractive interactions, leading to density profiles that are in between spherical cap and Gaussian shapes. We also develop an analytic mean field approach to explain the diffusive behavior of chainlike molecules. The thermodynamic factor in $D_C(θ)$ is evaluated using effective free energy arguments, and the chain mobility is calculated numerically using the recently developed dynamic mean field theory. Good agreement is obtained between theory and simulations.

description: The development of compact accelerator facilities providing high-brightness beams is one of the most challenging tasks in field of next-generation compact and cost affordable particle accelerators, to be used in many fields for industrial, medical and research applications. The ability to shape the beam longitudinal phase-space, in particular, plays a key role to achieve high-peak brightness. Here we present a new approach that allows to tune the longitudinal phase-space of a high-brightness beam by means of a plasma wakefields. The electron beam passing through the plasma drives large wakefields that are used to manipulate the time-energy correlation of particles along the beam itself. We experimentally demonstrate that such solution is highly tunable by simply adjusting the density of the plasma and can be used to imprint or remove any correlation onto the beam. This is a fundamental requirement when dealing with largely time-energy correlated beams coming from future plasma accelerators.
