description: We perform a study on the impacts on Ceres and Vesta. We aim to determine the size-frequency distribution (SFD) of impactors and to identify and quantify the contribution of each source region, as well as the craters produced and fragments ejected in these impact events. We used a multipart collisional evolution model of the MB called ACDC (Asteroid Collisions and Dynamic Computation) that simulates the collisional evolution of the MB, which is split into six regions (namely Inner, Middle, Pristine, Outer, Cybele, and High-Inclination belts). Furthermore, it includes the Yarkovsky effect as a dynamical remotion mechanism. The six regions of the MB provide, to a greater or lesser extent, impactors on Ceres and Vesta. The Outer belt is the main source of impactors smaller than 10 km on Ceres, providing more than half of the impacts, while the Middle belt is the secondary source. On Vesta, the relative impactor contribution of the Inner, Middle, and Outer belts is almost even. We are able to reproduce the craters larger than 100 km in Vesta and identify two large depressions identified in Ceres as impact craters: one called Vendimia Planitia of 900 km and a second one of 570 km. As an outcome of these impacts, Ceres and Vesta eject fragments into the MB. We obtain fragmentation rates of tens of fragments larger than 1 m per year for both bodies, to tens of fragments larger than 100 m per million years for Vesta and a factor of 4 greater for Ceres. We find that hundreds of bodies larger than 10 km should have been ejected from Ceres and Vesta during their history

description: We introduce generalized Frobenius-Schur indicators for pivotal categories. In a spherical fusion category C, an equivariant indicator of an object in C is defined as a functional on the Grothendieck algebra of the quantum double Z(C) via generalized Frobenius-Schur indicators. The set of all equivariant indicators admits a natural action of the modular group. Using the properties of equivariant indicators, we prove a congruence subgroup theorem for modular categories. As a consequence, all modular representations of a modular category have finite images, and they satisfy a conjecture of Eholzer. In addition, we obtain two formulae for the generalized indicators, one of them a generalization of Bantay's second indicator formula for a rational conformal field theory. This formula implies a conjecture of Pradisi-Sagnotti-Stanev, as well as a conjecture of Borisov-Halpern-Schweigert.

description: Linear precoded discrete multitone modulation (LP-DMT) system has been already proved advantageous with adaptive resource allocation algorithm in a power line communication (PLC) context. In this paper, we investigate the bit and energy allocation algorithm of an adaptive LP-DMT system taking into account the channel coding scheme. A coded adaptive LP-DMT system is presented in the PLC context with a loading algorithm which ccommodates the channel coding gains in bit and energy calculations. The performance of a concatenated channel coding scheme, consisting of an inner Wei's 4-dimensional 16-states trellis code and an outer Reed-Solomon code, in combination with the roposed algorithm is analyzed. Simulation results are presented for a fixed target bit error rate in a multicarrier scenario under power spectral density constraint. Using a multipath model of PLC channel, it is shown that the proposed coded adaptive LP-DMT system performs better than classical coded discrete multitone.

description: Medienerziehung und Medienbildung spielen nach wie vor eine marginale Rolle in der pädagogischen Praxis von Einrichtungen der frühkindlichen Bildung in Deutschland. Welcher Bedeutung Medienerziehung und -bildung auf der Ebene von Handlungsleitfäden und Curricula in den Bildungsplänen der Bundesländer zukommen, wurde mittels einer Dokumentenanalyse der Bildungspläne für den (früh)kindlichen Bereich, der Lehrpläne der ErzieherInnen-Ausbildung sowie von Modulplänen und Studienführern früh- und kindheitspädagogischer Studiengänge qualitativ erforscht. Zentrale Ergebnisse der Analyse sind, dass medienpädagogische Inhalte vielfach nur schlaglichtartig aufgegriffen werden und sich teilweise deutlich ablehnende medienbezogene e Haltungen widerspiegeln. Eine formale Verortung von Inhalten der Medienerziehung/-bildung als separater Bildungs- bzw. Modulbereich ist kein Garant für eine an aktuellen medienpädagogischen Diskursen und sowohl Chancen als Risiken von Mediennutzung ausgerichtete Darstellung.

description: Distribution in the Major Ecoclimatic Regions We present the distribution of Alberta Lepidoptera among the three major ecoclimatic regions in Alberta (Ecoregions Working Group 1989): Mountain (M/m), Boreal (B/b), and Grassland (G/g), in that order. An uppercase letter indicates that the species inhabits the prevalent habitat type (s) in the region; alpine, subalpine, or montane in the Mountain region; boreal forest in the Boreal region; or grasslands in the Grassland region. A lowercase letter is used for species with limited occurrence in that region. For example, a species that is known only from small patches of grassland within the Boreal region would be indicated by “b,” and a species known only from small forested patches within the Grassland region would be indicated by “g.” A dash indicates that the species does not normally occur in that region. Species found only in the foothills, largely a transitional region between the Mountain and Boreal ecoclimatic regions, are indicated by “m b.” Species found only in the parkland, largely a transitional region between the Boreal and Grassland ecoclimatic regions, are indicated by “b g.” We obtained this information from the references and collections cited in the sections on taxonomic information and/or sources of Alberta records for the species in question, as well as the authors’ personal unpublished data.

description: In this paper, we propose a novel channel estimation technique based on 2D spread pilots. The merits of this technique are its simplicity, its flexibility regarding the transmission scenarios, and the spectral efficiency gain obtained compared to the classical pilot based estimation schemes used in DVB standards. We derive the analytical expression of the mean square error of the estimator and show it is a function of the autocorrelation of the channel in both time and frequency domains. The performance evaluated over a realistic channel model shows the efficiency of this technique which turns out to be a promising channel estimation for the future mobile video broadcasting systems.

description: La migración es un motor demolingüístico del español en Europa. En las últimas décadas, España se ha convertido en uno de los destinos migratorios más importantes de Europa. Una de las consecuencias de estos movimientos migratorios es la adquisición de competencias lingüísticas por parte de los migrantes, que pasan a formar parte de la comunidad hispanohablante a través de diferentes procesos de integración sociolingüística. El objetivo de este documento es abordar los retos que supone la migración no lineal para las políticas lingüísticas del español en Europa. Más concretamente, el documento ofrece una cuantificación de los movimientos migratorios de retorno que contribuyen a la demolingüística del español en Europa, identifica distintos perfiles de hablantes y, a partir del estudio de caso de los menores retornados de Rumanía, propone algunas acciones concretas que podrían facilitar la (re)integración de estas personas en las sociedades de retorno desde el punto de vista de las políticas educativas favorables para el bilingüismo migratorio.

description: In this work, we study the propagation of solitons in lossy optical fibers. The main objective of this work is to study the loss of energy of the soliton wave during propagation and then to evaluate the impact of this loss on the transmission of the soliton signal. In this context, a numerical scheme was developed to solve a system of complex partial differential equations (CPDE) that describes the propagation of solitons in optical fibers with loss and nonlinear amplification mechanisms. The numerical procedure is based on the mathematical theory of Taylor series of complex functions. We adapted the Finite Difference Method (FDM) to approximate derivatives of complex functions. Then, we solve the algebraic system resulting from the discretization, implicitly, through the relaxation Gauss-Seidel method (RGSM). The numerical study of CPDE system with linear and cubic attenuation showed that soliton waves undergo attenuation, dispersion, and oscillation effects. On the other hand, we find that by considering the nonlinear term (cubic term) as an optical amplification, it is possible to partially compensate for the attenuation of the optical signal. Finally, we show that a gain of 9% triples the propagation distance of the fundamental soliton wave, when the dissipation rate is 1%.

The effect of thyroidectomy on the responsiveness of rat atria to adrenergic amines
Creators: name: Simpson, William Wilson
Publisher: name: University of British Columbia
Year: 2010

description: To examine effects of thyroid state on cardiac adrenoceptor sensitivity, left and right atria isolated from male euthyroid and hypothyroid rats were exposed to the agonists methoxamine, isoproterenol and phenylephrine and to the antagonists (10⁻⁶M) phenoxybenzamine, phentolamine and propranolol. Isoproterenol and phenylephrine increased rate and force of both euthyroid and hypothyroid atria. Methoxamine also increased force of euthyroid and hypothyroid atria, but increased the rate of hypothyroid atria only. In all cases in which a response was observed, the hypothyroid state increased the potency of methoxamine and of phenylephrine, and decreased the potency of isoproterenol. The hypothyroid state also increased the inotropic and chronotropic effectiveness of methoxamine, but did not alter the maximum responses to phenylephrine or isoproterenol. Phenoxybenzamine abolished all responses to methoxamine, but only partially inhibited the effects of phenylephrine. Propranolol had no effect on the responses to methoxamine, blocked the chronotropic response to phenylephrine, and blocked the inotropic and chronotropic responses to isoproterenol. In the presence of the cholinergic agonist carbachol, the basal rate and force of euthyroid right and left atria, respectively, were decreased to the basal level observed in the hypothyroid controls. Methoxamine was found to increase both rate and force in the treated euthyroid atria similar to that observed in the hypothyroid controls. Conversely, in the presence of the adrenergic agonist isoproterenol, the basal rate and force of hypothyroid right and left atria, respectively, were increased to the basal level observed in the euthyroid controls. The hypothyroid atria then responded to methoxamine as was observed in the euthyroid right and left atria. Methoxamine was found to have no effect on cyclic AMP production in either the euthyroid or hypothyroid left or right atria, even though a greater increase in both rate and force was observed in the hypothyroid right and left atria, respectively, as compared to the euthyroid atria. While the hypothyroid state decreased the potency of isoproterenol on the force of contraction and atrial rate, it did not affect the cyclic AMP response to this beta adrenoceptor agonist. Isoproterenol increased cyclic AMP production, rate and force to the same extent in both the euthyroid and hypothyroid right and left atria. The data of the present study do not support the hypothesis that rat heart adrenoceptors undergo a conversion from beta to alpha in the hypothyroid state, in terms of cyclic AMP production, atrial rate and force development. The data do, however, support the hypothesis that there is an increased alpha adrenoceptor responsiveness in the hypothyroid state as compared to the euthyroid state.
Lipid-protein interactions: A., Semliki forest virus : B., CTP:phosphocholine cytidylyltransferase from rat liver
Creators: name: Farren, S. Blake

description: A. Semliki Forest virus: Lipid Headgroup-Protein Interactions Semliki Forest virus is an alphavirus enveloped by a lipid bilayer that contains approximately 200 copies each of three glycoproteins: E₁, molecular weight 49,000, E₂, molecular weight of 52,000, and E₃, molecular weight of 10,000. Proton magnetic resonance measurements were done on intact Semliki Forest virus and virus that had been digested with thermolysin. The magnetic resonance line derived from a portion of the N-methyl groups of the choline containing phospholipids narrowed considerably after proteolytic digestion. This reduction in the N-methyl resonance is not inconsistent with increased motion of the headgroups of the phospholipids as a result of thermolysin removal of the viral glycoprotein spikes. To further investigate this phenomenon, experiments were planned using deuterium NMR. Tri-trideuteromethylcholine was chemically synthesized and added to the medium of BHK-21 cells with the hope of labelling a large majority of the choline containing lipids. However, no incorporation of this labelled species could be observed. Two other deuter-ated cholines, mono-trideuteromethylcholine and di-trideuteromethylchloline, were synthesized and easily incorporated into the BHK-21 cell choline containing lipids. Due to the low yields of Semliki Forest virus, deuterium NMR could not be performed, however, the lack of incorporation of tri-trideuteromethyl choline was of interest. From labelling studies it was concluded that this deuterated choline was not transported across the cell plasma membrane. B. CTP:phosphocholine Cytidylyltransferase: Lipid-Protein Interactions Early studies on the rat liver CTP:phosphocholine cytidylyltransferase (E.C. 2.7.7.15) (CT) reported that the enzyme isolated from the cytosolic fraction of"0.9% NaCl solution homqgena-tes increased in activty 4- to 5-fold upon aging several days at 0°C or incubation at 37°C for 3 hours. It was subsequently shown that the activating agent was lysophospha-tidylethanolamine (LPE). We have demonstrated that the purified rat liver CT is dependent upon lipid for acitvity and is activated by oleoyl-LPE and inhibited by oleoyl-lysophosphatidylcholine (LPC). The plot of CT activity at various concentrations of LPE yields a hyperbolic curve with a Ka of 0.3 mM. The activation of CT by LPE results in a decrease of the Km for CTP from 2 mM at 0.1 mM LPE, to 0.5 mM at 0.4 mM LPE. LPE had no effect on the Km for phosphocholine. Hence, the activation of CT by LPE is due to an influence on the Km for CTP. When CT is assayed in the presence of LPE, LPC inhibits the activity with a concentration for half-maximal inhibition of 0.16 mM. Inhibition by LPC was not competitive with phosphocholine.

The elongate–oval wings are often iridescent and are covered with long, hairlike scales. Th e wings are usually held like a tent over the body when at rest. Th is group can be separated from most other moths by the vestigial mandibles, and from the Acanthopteroctetidae by the presence of ocelli. Adults are diurnal, and most species fly early in the spring. Larvae are leaf blotch miners. Twenty-four species of eriocraniids are known worldwide, all from the Holarctic. Th irteen species occur in North America; only one is known from AB. The family was revised by Davis (1978a); a few more species may await discovery. 1 * R Eriocrania semipurpurella (Stephens, 1834) M Apr – L May – B – T: Davis (1978a) L: Pohl et al.

description: The magnetic moment ($a_γ$) and weak magnetic moment ($a_W$) of charged leptons and quarks are sensitive to quantum effects of new physics heavy resonances. In effective field theory $a_γ$ and $a_W$ are induced by two independent operators, therefore, one has to measure both the $a_γ$ and $a_W$ to shed lights on new physics. The $a_W$'s of the SM fermions are measured at the LEP. In this work, we analyze the contributions from magnetic and weak magnetic moment operators in the processes of $pp\to H γ$ and $gg\to H \to τ^+ τ^- γ$ at the High-Luminosity Large Hadron Collider. We demonstrate that the two processes could cover most of the parameter space that cannot be probed at the LEP.

description: Improving working conditions in agriculture is of great concern throughout the world. Just as in other industries, many young farm workers prefer to work as salaried employees, which has brought attention to non-family farms as providers of employment opportunities. However, in the presence of a strong need to flexibly respond to weather, there is still difficulty regarding whether workplaces without overworking can exist. This study is based on in-depth surveys of non-family rice farms in Fukui Prefecture, Japan. Our findings suggest that even in non-family farms, holiday-setting is done flexibly to account for weather, and systems that allow for harvesting at appropriate times are in place. During the busy farming period, in joint-stock farms, where multiple farmers invest together, full-time employees work overtime. In contrast, in community farms, many community residents take turns for working, which allows work to be done on time. A closer analysis of work records shows that, in either organizational structure, specific members need to overwork. Reasons behind this include issues with sunk costs in the form of monthly wages, lack of skills among part-time employees, and the communication costs of coordinating with many part-time employees.

description: A Hermitian metric on a complex manifold of complex dimension $n$ is called {\em astheno-Kähler} if its fundamental $2$-form $F$ satisfies the condition $\partial \overline \partial F^{n - 2} =0$. If $n =3$, then the metric is {\em strong KT}, i.e. $F$ is $\partial \overline \partial$-closed. By using blow-ups and the twist construction, we construct simply-connected astheno-Kähler manifolds of complex dimension $n > 3$. Moreover, we construct a family of astheno-Kähler (non strong KT) $2$-step nilmanifolds of complex dimension $4$ and we study deformations of strong KT structures on nilmanifolds of complex dimension $3$. Finally, we study the relation between astheno-Kähler condition and (locally) conformally balanced one and we provide examples of locally conformally balanced astheno-Kähler metrics on $\T^2$-bundles over (non-Kähler) homogeneous complex surfaces.

description: According to the WHO, in the modern treatment and diagnostic process of cholelithiasis (CSD) it is important, especially in individuals of the gerontological group (75-90 years and above), not only to provide scientific information on a certain type of treatment (surgical or conservative) and clinical and fundamental recommendations, but also to acquire modern innovative technologies acceptable for preventive surgery and the ability to use them. For the advanced development of CSD surgery in the 21st century, it is important to identify the most susceptible individuals with high or very high risk for this pathology and their special prevention to ensure the process of early detection, effective and safe treatment (with proper pharmacovigilance, pharmacoepidemiological screening) and the prevention of not only CSD itself, but also formidable complications of cholecystectomy, cholecystostomy, choledochotomy, choledochomyotomy and transduodenal sphincteropapillotomy.

description: We present explicit analytic results for the two-loop top/stop/gluino contributions to the cross section for the production of CP-even Higgs bosons via gluon fusion in the MSSM, under the approximation of neglecting the Higgs boson mass with respect to the masses of the particles circulating in the loops. The results are obtained employing the low-energy theorem for Higgs interactions adapted to the case of particle mixing. We discuss the validity of the approximation used by computing the first-order correction in an expansion in powers of the Higgs boson mass. We find that, for the lightest CP-even Higgs boson, the gluino contribution is very well approximated by the result obtained in the limit of vanishing Higgs mass. As a byproduct of our calculation, we provide results for the two-loop QCD contributions to the photonic Higgs decay.

description: We present the first comparison between numerical relativity (NR) simulations of an eccentric binary black hole system with corresponding post-Newtonian (PN) results. We evolve an equal-mass, non-spinning configuration with an initial eccentricity e ~ 0.1 for 21 gravitational wave cycles before merger, and find agreement in the gravitational wave phase with an adiabatic eccentric PN model with 2 PN radiation reaction within 0.1 radians for 10 cycles. The NR and PN phase difference grows to 0.7 radians by 5 cycles before merger. We find that these results can be obtained by expanding the eccentric PN expressions in terms of the frequency-related variable x = (omega M)^{2/3} with M the total mass of the binary. When using instead the mean motion n = 2 π/P, where P is the orbital period, the comparison leads to significant disagreements with NR.

description: WR 140 is a long-period, highly eccentric Wolf-Rayet star binary system with exceptionally well-determined orbital and stellar parameters. Bright, variable X-ray emission is generated in shocks produced by the collision of the winds of the WC7pd+O5.5fc component stars. We discuss the variations in the context of the colliding-wind model using broad-band spectrometry from the RXTE, SWIFT, and NICER observatories obtained over 20 years and nearly 1000 observations through 3 consecutive 7.94-year orbits including 3 periastron passages. The X-ray luminosity varies as expected with the inverse of the stellar separation over most of the orbit: departures near periastron are produced when cooling shifts to excess optical emission in CIII $\lambda5696$ in particular. We use X-ray absorption to estimate mass-loss rates for both stars and to constrain the system morphology. The absorption maximum coincides closely with inferior conjunction of the WC star and provides evidence of the ion-reflection mechanism that underlies the formation of collisionless shocks governed by magnetic fields probably generated by the Weibel instability. Comparisons with K-band emission and HeI $λ$10830 absorption show that both are correlated after periastron with the asymmetric X-ray absorption. Dust appears within a few days of periastron suggesting formation within shocked gas near the stagnation point. X-ray flares seen in $η$ Carinae have not occurred in WR 140, suggesting the absence of large-scale wind inhomogeneities. Relatively constant soft emission revealed during the X-ray minimum is probably not from recombining plasma entrained in outflowing shocked gas.

description: We characterize (in almost all cases) the holomorphic self-maps of the unit disk that intertwine two given linear fractional self-maps of the disk. The proofs are based on iteration and a careful analysis of the Denjoy-Wolff points. In particular, we characterize the maps that commute with a given linear fractional map (in the cases that are not already known) and, as an application, determine all "roots" of such maps in the sense of iteration (if any). This yields as a byproduct a short proof of a recent theorem on the embedding of a linear fractional transformation into a semigroup of holomorphic self-maps of the disk.

description: The hydrodynamics of the interaction of pulsar and stellar winds in binary systems harboring a pulsar and its impact on the nonthermal radiation of the binary pulsar PSR B1259-63/SS2883 is discussed. The collision of an ultrarelativistic pulsar wind with a nonrelativistic stellar outflow results in significant bulk acceleration of the shocked material from the pulsar wind. Already at distances comparable to the size of the binary system, the Lorentz factor of the shocked flow can be as large as $γ$~4. This results in significant anisotropy of the inverse Compton radiation of accelerated electrons. Because of the Doppler boosting of the produced radiation, one should expect a variable gamma-ray signal from the system. In particular, this effect may naturally explain the reported tendency of a decrease of TeV gamma-ray flux close to the periastron. The modeling of the interaction of pulsar and stellar winds allows self-consistent calculations of adiabatic losses. Our results show that adiabatic losses dominate over the radiative losses. These results have direct impact on the orbital variability of radio, X-ray and gamma-ray signals detected from the binary pulsar PSR 1259-63/SS2883.

description: We expose the role of collisional energy loss on high $p_T$ photon data measured by PHENIX collaboration by calculating photon yield in jet plasma interaction. The phase space distribution of the participating jet is dynamically evolved by solving Fokker-Planck equation. It is shown that the data is reasonably well reproduced when contributions from all the relevant sources are taken into account. Predictions at higher beam energies relevant for LHC experiment have been made.

description: 4. Nepticulidae – pygmy eye-cap moths Minute (3–10 mm wingspan) moths with variable wing patterns. Th ey can be separated from most other minute moths via the combination of the rough-scaled head, presence of an antennal eye cap, and primitive wing venation. Th ey can be separated from Opostegidae by the presence of extensive dark areas on the forewings. Larvae are leafminers. Approximately 800 species of Nepticulidae are known worldwide, with many more remaining to be discovered. Ninety-seven species are known in North America. This family has been poorly collected in western North America; three species are reported from AB, but other species likely occur here as well. Th e Canadian Nepticulidae were revised by Wilkinson and Scoble (1979), but some of that work has been superseded by Wilkinson (1979, 1981), Wilkinson and Newton (1981), and Newton and Wilkinson (1982).

description: Commonly used metrics for evaluation of object detection systems (precision, recall, mAP) do not give complete information about their suitability of use in safety critical tasks, like obstacle detection for collision avoidance in Autonomous Vehicles (AV). This work introduces the Risk Ranked Recall ($R^3$) metrics for object detection systems. The $R^3$ metrics categorize objects within three ranks. Ranks are assigned based on an objective cyber-physical model for the risk of collision. Recall is measured for each rank.

Bulk and surface localized states on a magnetic nonlinear impurity

Year: 2008
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: We study localized modes on a single magnetic impurity positioned in the bulk or at the surface of a one-dimensional chain, in the presence of a magnetic field $B$ acting at the impurity site. The strong on-site nonlinear interaction $U$ between two electrons of opposite spin at the impurity site, modelled here as a nonlinear local term, and the presence of the external field induce a strong correlation between parallel and anti-parallel spin bound states. We find that, for an impurity in the bulk, a localized vector mode (with up and down spin components) is always possible for any given value of $U$ and $B$, while for a surface impurity, a minimum value of both, $U$ and $B$ is needed to create a vector mode. In this case, up to two localized modes are possible, but only one of them is stable. The presence of the surface seems to destabilize the bulk mode in the parameter region U~B, creating a "forbidden strip" region in parameter space, bounded by U=B+V and U=B-V, approximately.

description: Three very massive clusters are known to reside in the Galactic Center region, the Arches cluster, the Quintuplet cluster and the Central parsec cluster. We obtained spectroscopic observations of the Quintuplet cluster with the Integral Field Spectrograph SINFONI-SPIFFI at the ESO-VLT. The spectral range comprises the near-IR K-band from 1.94 to 2.45 micrometer. The 3D data cubes of the individual fields were flux-calibrated and combined to one contiguous cube, from which the spectra of all detectable point sources were extracted. We present a catalog of 160 stellar sources in the inner part of the Quintuplet cluster.
