Constraining the dipole moments of the top quark

DESY, Notkestrasse 85, D-22603 Hamburg, Germany(Dated: July 18, 2011)We investigate the direct and indirect bounds on dipole operators involving the top quark. Acareful analysis shows that the experimental upper limit on the neutron electric dipole momentstrongly constrains the chromo-electric dipole of the top. We improve previous bounds by twoorders of magnitude. This has signi cant implications for new physics models and it also meansthat CP violation in top pair production mediated by dipole operators will not be accessible at theLHC. The CP conserving chromo-magnetic dipole moments are constrained by recent measurementsof the ttspectrum by the ATLAS collaboration. We also update the indirect constraints on electricand magnetic dipole moments from radiative b! stransitions, nding that they can be considerablylarger than their colored counterparts.Introduction
Distributed Nonlinear Filtering Under Packet Drops and Variable Delays for Robotic Visual Servoing

State estimation over communication networks is in use by many robotic applications in industry, in defense systems, as well as in several exploration and surveillance tasks. The incorporation of a communication network in the control loop has enabled to perform multi-sensor fusion and distributed information processing, thus improving significantly the autonomy and reliability of robotic systems (Medeiros et al., 2008), (Olfati-Saber, 2006), (Watanabe & Tzafestas, 1992). It has been shown that scalable distributed state estimation can be achieved for robotic models, when the measurements are linear functions of the state and the associated process andmeasurement noise models follow aGaussian distribution (Mahler, 2007), (Nettleton et al., 2003). The results have been also extended to the case of nonlinear non-Gaussian dynamical systems (Rigatos, 2010a), (Makarenko & Durrant-Whyte, 2006). An issue which is associated to the implementation of such networked control systems is how to compensate for randomdelays and packet losses so as to enhance the accuracy of estimation and consequently to improve the stability of the control loop. The idea of incorporating delayed measurements within a Kalman Filter framework is a possible solution for the compensation of network-induced delays and packet losses, and is also known as update with out-of-sequence measurements (Bar Shalom, 2002). The solution proposed in (Bar Shalom, 2002) is optimal under the assumption that the delayed measurement was processed within the last sampling interval (one-step-lag problem). There have been also some attempts to extend these results to nonlinear state estimation (Golapalakrishnan et al., 2011), (Jia et al., 2008). More recently there has been research effort in the redesign of distributed Kalman Filtering algorithms for linear systems so as to eliminate the effects of delays in measurement transmissions and packet drops, while also alleviating the one-step-lag assumption (Xia et al., 2009). This chapter presents an approach to distributed state estimation-based control of nonlinear systems, capable of incorporating delayed measurements in the estimation algorithm while being also robust to packet losses. First, the chapter examines the problem of distributed nonlinear filtering over a communication/sensors network, and the use of the estimated state vector in a control loop. As a possible filtering approach, the Extended Information Filter is proposed (Rigatos, 2010a). In the Extended Information Filter the local filters do not exchange rawmeasurements but send to an aggregation filter their local information matrices (local inverse covariance matrices which can be also associated to Fisher Information Matrices) and their associated Distributed Nonlinear Filtering Under Packet Drops and Variable Delays for Robotic Visual Servoing 5
Toward a Greater Understanding of Antigay Prejudice: On the Role of Sexual Orientation and Gender Role Violation

Prejudice against gay men and lesbians could be driven by at least two types of expectancy violations: those pertaining to sexual orientation per se, and perceived violations of traditional gender roles (e.g., the fact that gay men are often inferred to be feminine and lesbians to be masculine). However, it is unclear whether one or the other (or both) of these expectancy violations are actually important in driving prejudicial reactions. In a completely crossed design, participants were asked to evaluate a target who varied with respect to biological sex, sexual orientation, and gender role (i.e., whether they were masculine or feminine). In addition, we also examined the contingency of these variables on preexisting individual differences in prejudice toward gay men and lesbians as a whole. Results showed a moderate trend among high prejudice participants to disparage “double violators,” that is, individuals who simultaneously violate expectations about both sexuality and gender roles. Implications for current research and practice are discussed.
The Interaction of a Two-Layer Isolated Mesoscale Eddy With Bottom Topography

Abstract The propagation of an isolated mesoscale eddy onto a western bounding topographic slope is examined through the use of a two-layer, primitive equation, numerical model. Variable parameters in the study are sense of rotation (cyclonic/anticyclonic), vertical structure (baroclinic, barotropic), and layer thickness ratio (H1/H2). Eddy size and strength (rotational velocity) and frictional parameterization are fixed. Dispersion in the isolated eddy is induced by planetary and topographic beta-effects, giving the eddy an asymmetric distribution. This asymmetric distribution allows for nonlinear self-advective propagation tendencies. These nonlinear tendencies play a key role in the direction of propagation of the eddy. Specifically, in a quiescient background, an anticyclone can have eastward propagation tendencies which can overcome planetary and topographic beta-effects. Conversely, cyclones can have westward propagation velocities which are augmented (greater than maximum Rossby wave phase speed) b.
Advanced EFL Learners' Beliefs about Language Learning and Teaching: A Comparison Between Grammar, Pronunciation, and Vocabulary

This paper reports on the results of a study exploring learners' beliefs on the learning and teaching of English grammar, pronunciation, and vocabulary at tertiary level. While the importance of learners' beliefs on the acquisition process is generally recognized, few studies have focused on and compared learners' views on different components of the language system. A questionnaire containing semantic scale and Likert scale items probing learners' views on grammar, pronunciation, and vocabulary was designed and completed by 117 native speakers of Dutch in Flanders, who were studying English at university. The analysis of the responses revealed that (i) vocabulary was considered to be different from grammar and pronunciation, both in the extent to which an incorrect use could lead to communication breakdown and with respect to the learners' language learning strategies, (ii) learners believed in the feasibility of achieving a native-like proficiency in all three components, and (iii) in-class grammar, pronunciation and vocabulary exercises were considered to be useful, even at tertiary level. The results are discussed in light of pedagogical approaches to language teaching.
Taxing Women : A Macroeconomic Analysis Extended Abstract

Perhaps the most signi cant change in the U.S. labor force during the 20th century has been the extremely rapid increase in female labor force participation. Female labor force participation increased from 38% to 60% between 1960 and 2008. This increase has been even more dramatic for married women, from 35% to 61%, and in particular for women with young (under age 6) children, from 19% to 62%. As a result, women today constitute a much larger fraction of total labor force. In 1960 females were about a third of the total labor force, while today 46% of the total labor force are females, and in about 65% of married households both husbands and wives work.2 There are still, however, important di¤erences between male and female labor supply decisions, reecting mainly the importance of children. First, children continue playing a key role in female labor force participation decisions and the marginal e¤ect of children have been relatively stable in last couple decades (Cohany and Sok, 2007; Ho¤man, 2009). Between 1994 and 2005, married females with children under 1 were much less likely to work than married females with children between ages 6 and 17 (55% versus 75%, respectively). Second, birth and child care are a central reason for why females do not work. Dalirazar (2007) reports than in 2004 about 40% of females between ages 20 and 64 list birth or child care as the main reason why they do not participate in the labor force. The link between children and female labor force participation hinges, leaving biological constraints aside, on the high resource costs of child care. In 2005, total child care expenditure of married females with children under 5, who made any child care payments, was about 17% of mothers income.3 Not surprisingly, this fraction is higher for women with 1Guner, ICREA-MOVE, Universitat Autonoma de Barcelona, Barcelona GSE; Kaygusuz, Faculty of Arts and Social Sciences, Sabanci University, Turkey; Ventura, Department of Economics, University of Iowa, USA. 2Calculations are based on data published in The 2010 Statistical Abstract by the U.S. Census Bureau, http://www.census. gov/compendia/statab/. 3Based on the U.S. Census Bureau estimates, http://www.census. gov/population/www/socdemo/childcare.html
Neutron star crust cooling in the Terzan 5 X-ray transient Swift J174805.3-244637

When neutron stars reside in transient X-ray binaries, their crustal layers become heated during accretion outbursts and subsequently cool in quiescence. Observing and modelling this thermal response has yielded valuable insight into the physics of neutron star crusts. However, one unresolved problem is the evidence in several neutron stars for an extra energy source, located at shallow depth in the crust, that is not accounted for by standard heating models. Its origin remains puzzling, and it is currently unclear whether this additional heating occurs in all neutron stars, and if the magnitude is always the same. Here, we report on Chandra observations that cover two years after the 2012 outburst of the transient neutron star X-ray binary Swift J174805.3–244637 in the globular cluster Terzan 5. The temperature of the neutron star was elevated during the first two months following its ? 8 week accretion episode, but had decayed to the pre-outburst level within ? 100 d. Interpreting this as rapid cooling of the accretion-heated crust, we model the observed temperature curve with a thermal evolution code. We find that there is no need to invoke shallow heating for this neutron star, although an extra energy release up to ? 1.4 MeV nucleon? 1 is allowed by the current data (2? confidence). We also present two new data points on the crust-cooling curve of the 11-Hz X-ray pulsar IGR J17480–2446 in Terzan 5, which was active in 2010. The temperature of this neutron star remains significantly above the pre-outburst level, but we detect no change in the thermal emission since the previous measurements of 2013 February. This is consistent with the slow crust cooling expected several years post-outburst.
Intelligent V 2 I-Based Traffic Management System

Vehicles equipped with intelligent systems capable of preventing accidents as collision warning system (CWS) or lanekeeping assistance (LKA) are presently in the market. Next step in the reduction of road accidents is based on the coordination of these vehicles in advance for not only avoiding collisions but also improving the traffic flow. To this end, vehicle-to-infrastructure (V2I) communications are mandatory to manage properly traffic situations. This paper presents AUTOPIA approach toward an intelligent traffic management system based on V2I communications. A fuzzy-based control algorithm that take into account a safe and comfortable distance and speed adjustment of each vehicles in order to prevent collisions has been developed. A communication study based on IEEE 802.11p to validate the proposed solution is presented. The whole system has been tested in real scenarios both in simulation and with real vehicles with a good performance.
Performance Enhancement of Atbara-Portsudan Radial Transmission Line Using NEPLAN Simulator

Due to the ever increasing demand of power, economic and environmental constraints that limit the expansion and restructuring transmission networks, the transmission lines are prone to be operated under heavily stress conditions, and power systems to operate near critical limits. This paper investigates the problem and different scenarios to improve the power transfer capability of Atbara-Portsudan single circuit 220kV radial transmission line as one of the Sudan Grid problems. This line was selected depending on line indices such as Fast Voltage Stability Index (FVSI), Line Stability Index (Lmn), U-Q sensitivities. Simulation was carried out using NEPLAN software, based on real data given from National Load Dispatch Center (NLDC) in Sudan. All the results presented in comparison form to find the best scenario.
Some background for Manin ’ s theorem K ( F 1 ) ∼ S

The techniques Quillen pioneered generalize those of classical homological algebra; in his language a resolution can be interpreted as a kind of homotopy-equivalent replacement with better properties. This has deep roots in earlier work of Dold, Kan, and others on non-abelian homological algebra, which Quillen first applied to Grothendieck’s program for the construction of a cotangent complex for morphisms of commutative rings; but his theory of (what are now called) model categories1 does not require the categories of interest to be additive.
Implications of government funding of advocacy for third-sector independence and exploration of alternative advocacy funding models

This paper examines the effect of funding contracts on the capacity of third-sector organizations to effectively advocate. The relationship is not simple or obvious, with some organizations reporting 'mature relationships' with particular (state) departments, and others reporting difficulty with state or federal government jurisdictions. The paper spells out the negative effects of conflating service funding and advocacy. The paper concludes by exploring alternative institutional arrangements for the resourcing of advocacy including the establishment of a Public Interest Fund administered independently of any government department, one not requiring specific service contracts but rather evidence that it is advocating for the broader public good.
GnRH agonist enhances autophagy in a mouse model of adenomyosis

Gonadotropin-releasing hormone (GnRH) agonists are effective treatments for adenomyosis. Previous studies have suggested that autophagy in the eutopic endometrium is impaired in patients with adenomyosis. However, whether GnRH agonists act on autophagic mechanisms to exert their therapeutic effect remains unclear. Here we investigated the effect of a GnRH agonist on autophagy in a mouse model of adenomyosis. Mice in the model group showed significantly fewer autophagosomes and less Beclin 1, LC-3 expression in the eutopic endometrium than control mice. However, in model mice that received a GnRH agonist, significantly more autophagosomes and Beclin 1, LC-3 protein expression were observed than in model mice that received vehicle. These results indicate that adenomyosis causes inhibition of autophagy, but that this is reversed by GnRH agonists. The study contributes to an understanding of the roles of autophagy in the treatment of adenomyosis using GnRH agonists, and suggests that targeting aberrant autophagy might be a novel strategy for the treatment of adenomyosis.
Stellar population models at high spectral resolution

We present new, high-to-intermediate spectral resolution stellar population models, based on four popular libraries of empirical stellar spectra, namely Pickles, ELODIE, STELIB and MILES. These new models are the same as our previous models, but with higher resolution and based on empirical stellar spectra, while keeping other ingredients the same including the stellar energetics, the atmospheric parameters and the treatment of the thermally pulsating asymptotic giant branch and the horizontal branch morphology. We further compute very high resolution (R = 20 000) models based on the theoretical stellar library MARCS which extends to the near-infrared. We therefore provide merged high-resolution stellar population models, extending from ∼1000 to 25 000 A, using our previously published high-resolution theoretical models which extended to the ultraviolet. We compare how these libraries perform in stellar population models and highlight spectral regions where discrepancies are found. We confirm our previous findings that the flux around theV band is lower (in a normalized sense) in models based on empirical libraries than in those based on the BaSeL–Kurucz library, which results in a bluer B − V colour. Most noticeably the theoretical library MARCS gives results fully consistent with the empirical libraries. This same effect is also found in other models using MILES, namely Vazdekis et al. and Conroy & Gunn, even though the latter authors reach the opposite conclusion. The bluer predicted B − V colour (by 0.05 mag in our models) is in better agreement with both the colours of luminous red galaxies and globular cluster data. We test the models on their ability to reproduce, through full spectral fitting, the ages and metallicities of Galactic globular clusters as derived from colour–magnitude diagram (CMD) fitting and find overall good agreement. We also discuss extensively the Lick indices calculated directly on the integrated MILES-based spectral energy distributions (SEDs) and compare them with element ratio-sensitive index models. We find a good agreement between the two models, if the metallicity-dependent chemical pattern of the Milky Way stars is properly taken into account in this comparison. As a consequence, the ages and metallicities of Galactic globular clusters are not well reproduced when one uses straight the MILES-based indices, because subtle chemical effects on individual lines dominate the age derivation. The best agreement with the ages of the calibrating globular clusters is found with either element ratio-sensitive absorption-line models or the full SED fitting, for which no particular weight is given to selected lines.
Stimulation of Replication Template-Switching by DNA-Protein Crosslinks

Covalent DNA protein crosslinks (DPCs) are common lesions that block replication. We examine here the consequence of DPCs on mutagenesis involving replicational template-switch reactions in Escherichia coli. 5-Azacytidine (5-azaC) is a potent mutagen for template-switching. This effect is dependent on DNA cytosine methylase (Dcm), implicating the Dcm-DNA covalent complex trapped by 5-azaC as the initiator for mutagenesis. The leading strand of replication is more mutable than the lagging strand, which can be explained by blocks to the replicative helicase and/or fork regression. We find that template-switch mutagenesis induced by 5-azaC does not require double strand break repair via RecABCD; the ability to induce the SOS response is anti-mutagenic. Mutants in recB, but not recA, exhibit high constitutive rates of template-switching, and we suggest that RecBCD-mediated DNA degradation prevents template-switching associated with fork regression. A mutation in the DnaB fork helicase also promotes high levels of template-switching. We also find that other DPC-inducers, formaldehyde (a non-specific crosslinker) and ciprofloxacin (a topoisomerase II poison) are also strong mutagens for template-switching with similar genetic properties. Induction of mutations and genetic rearrangements that occur by template-switching may constitute a previously unrecognized component of the genotoxicity and genetic instability promoted by DPCs.
Professions in a globalizing world: Towards a transnational sociology of the professions

Globalization has significant implications for the professions, with the societies and the regulators around them changing and the realities of professional work in large organizations taking on increasingly transnational dimensions. However, while there is no lack of empirical studies of the globalization of individual professions and firms, the implications of processes of globalization, reregulation and governmental rescaling for neo-Weberian sociologies of the professions has not received the same attention. This article seeks to rectify this gap in knowledge by developing a transnational neo-Weberian sociology of the professions that takes account of the rescaling of the world that the professions inhabit and the important new research questions generated about the multi-scalar influences on the forms of regulation, power and legitimacy that underlie professional projects.
An Improved Switching Technique for a Non-Isolated High Step-Down Voltage Ratio DC-DC Converter

This paper focuses on a non-isolated high step-down voltage ratio DC-DC converter by addressing the PWM switching sequence problem, as well as proposing a new switching technique. The appropriate PWM switching sequence allows the converter to operate with very high conversion ratio, whereas the proposed technique offers a wide output voltage range of operation, maintaining however, the high step-down ratio characteristics. The converter operation under the appropriate PWM switching sequence and the proposed new one, is theoretically analyzed and validated using a laboratory experimental prototype.
Marmoset Personality 2 Common Marmoset ( Callithrix jacchus ) Personality 4 5

30 Increasing evidence suggests that personality structure differs between species, but the 31 evolutionary reasons for this variation are not fully understood. We built on earlier research 32 on New World monkeys to further elucidate the evolution of personality structure in 33 primates. We therefore examined personality in 100 family-reared adult common marmosets 34 (Callithrix jacchus) from three colonies on a 60-item questionnaire. Principal components 35 analyses revealed five domains that were largely similar to those found in a previous study on 36 captive, ex-pet, or formerly laboratory-housed marmosets that were housed in a sanctuary. 37 The interrater reliabilities of domain scores were consistent with the interrater reliabilities of 38 domain scores found in other species, including humans. Four domains---conscientiousness, 39 agreeableness, inquisitiveness, and assertiveness---resembled personality domains identified 40 in other nonhuman primates. The remaining domain, patience, was specific to common 41 marmosets. We used linear models to test for sex and age differences in the personality 42 domains. Males were lower than females in patience, and this difference was smaller in older 43 marmosets. Older marmosets were lower in inquisitiveness. Finally, older males and younger 44 females had higher scores in agreeableness than younger males and older females. These 45 findings suggest that cooperative breeding may have promoted the evolution of social 46 cognition and influenced the structure of marmoset prosocial personality characteristics. 47 48
