Magnetic flux inversion in Charged BPS vortices in a Lorentz-violating
  Maxwell-Higgs framework

We demonstrate for the first the existence of electrically charged BPS
vortices in a Maxwell-Higgs model supplemented with a parity-odd
Lorentz-violating (LV) structure belonging to the CPT-even gauge sector of the
standard model extension and a fourth order potential (in the absence of the
Chern-Simons term). The modified first order BPS equations provide charged
vortex configurations endowed with some interesting features: localized and
controllable spatial thickness, integer flux quantization, electric field
inversion and localized magnetic flux reversion. This model could possibly be
applied on condensed matter systems which support charged vortices carrying
integer quantized magnetic flux, endowed with localized flipping of the
magnetic flux.Comment: 6 Latex 2e pages, 5 figures. To appear in Physics Letters
Measurement of the CP-violating weak phase φs and the decay width difference δΓc using the Bs 0→J/ψφ(1020) decay channel in pp collisions at √ s=8 TeV

The CP-violating weak phase φs of the Bs0 meson and the decay width difference δΓs of the Bs0 light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of Bs0→J/ψφ(1020)→μ+μ-K+K- decays. The analysed data set corresponds to an integrated luminosity of 19.7fb-1 collected in pp collisions at a centre-of-mass energy of 8TeV. A total of 49 200 reconstructed Bs0 decays are used to extract the values of φs and δΓs by performing a time-dependent and flavour-tagged angular analysis of the μ+μ-K+K- final state. The weak phase is measured to be φs=-0.075±0.097(stat)±0.031(syst) rad, and the decay width difference is δΓs=0.095±0.013(stat)±0.007(syst) ps-1.The Scientific and Technical Research Council of Turkey, and Turkish Atomic Energy Authorit
Analytical solutions for the multi-term time-space Caputo-Riesz fractional advection-diffusion equations on a finite domain

Generalized fractional partial differential equations have now found wide application for describing important physical phenomena, such as subdiffusive and superdiffusive processes. However, studies of generalized multi-term time and space fractional partial differential equations are still under development. In this paper, the multi-term time-space Caputo-Riesz fractional advection diffusion equations (MT-TSCR-FADE) with Dirichlet nonhomogeneous boundary conditions are considered. The multi-term time-fractional derivatives are defined in the Caputo sense, whose orders belong to the intervals [0, 1], [1, 2] and [0, 2], respectively. These are called respectively the multi-term time-fractional diffusion terms, the multi-term time-fractional wave terms and the multi-term time-fractional mixed diffusion-wave terms. The space fractional derivatives are defined as Riesz fractional derivatives. Analytical solutions of three types of the MT-TSCR-FADE are derived with Dirichlet boundary conditions. By using Luchko's Theorem (Acta Math. Vietnam., 1999), we proposed some new techniques, such as a spectral representation of the fractional Laplacian operator and the equivalent relationship between fractional Laplacian operator and Riesz fractional derivative, that enabled the derivation of the analytical solutions for the multi-term time-space Caputo-Riesz fractional advection-diffusion equations. © 2012
Techniques for solar dosimetry in different environments

Minimization of solar UV exposures is necessary to reduce the risks of detrimental sun-related effects caused by overexposure to sunlight and vitamin D deficiency related diseases. Furthermore, agricultural production can be influenced by changes in solar UV and visible radiation due to atmospheric variability. Consequently, there is a requirement for a full understanding of the solar radiation environment. This chapter describes the development of dosimetric techniques for the measurement of solar UV exposures in different conditions in order to provide an improved characterization of the solar radiation environment for humans and plants. The erythemal exposures during normal daily activities and the effectiveness ofUV protective strategies have been measured with polysulphone dosimeters. These dosimeters have also been miniaturized in order to increase the number of environments in which they can be used. Additionally, polysulphone dosimeters have been employed with appropriate calibration to evaluate the pre-vitamin D3 effective UV exposure on humans, along with the UVB (280 nm -320 nm) exposures to plant leaves. The dynamic range of polysulphone has been extended by the development of a dosimeter that is based on polyphenylene oxide with a dynamic range that is approximately four times longer than that of polysulphone
Appropriateness of Default Investment Options in Defined Contribution Plans: The Australian Evidence

For participants in defined contribution (DC) plans who refrain from exercising investment choice, plan contributions are invested following the default investment option of their respective plans. Since default investment options of different plans vary widely in terms of their benchmark asset allocation, the most important determinant of investment performance, participants enrolled in these options face significantly different wealth outcomes at retirement. This paper simulates the terminal wealth outcomes under different static asset allocation strategies to evaluate their relative appeal as default investment choice in DC plans. We find that strategies with moderate allocation to stocks are consistently outperformed in terms of upside potential of exceeding the participant’s wealth accumulation target at retirement as well as downside risk of falling below that target outcome by very aggressive strategies whose allocation to stocks approach 100%. The risk of extremely adverse wealth outcomes for plan participants also does not appear to be very sensitive to asset allocation. Our evidence strongly suggests the appropriateness of strategies heavily tilted towards stocks to be nominated as default investment options in DC plans unless plan providers emphasize predictability of wealth outcomes over adequacy of retirement wealth.
Time Zones, Shift Working and International Outsourcing

We build a trade model with two identical countries located in different time
zones and a monopolistically competitive sector of which production requires differentiated
goods produced in two successive stages. We introduce shift working
disutility and allow consumers to choose between day and night shifts. Shift working
disutility raises the cost of night production and firms can reduce costs by
“virtually” outsourcing foreign labor. We found that firms only outsource if relative
costs of outsourcing are low and shift disutility is high. When outsourcing
occurs under free trade, it generates the highest level of welfare among production
modes. An intermediate range of shift working disutility can generate the lowest
level of welfare and be not affected by the reduction of outsourcing costs.
Satisfaction with and reasons for choosing faith-inspired health care provision in Ghana

This paper relies on household survey data as well as qualitative fieldwork to answer two questions about the services provided by faith-inspired health care providers in Ghana: how satisfied are patients with the services received?; and why are patients choosing faith-inspired providers for care? The quantitative survey data suggests that the level of satisfaction with the services provided by faith-inspired facilities is similar to that for public facilities, but lower than for private non-religious facilities. The qualitative data suggests that the reasons that lead patients to choose faith-inspired providers are not related to religion per se, but rather to the quality of the services provided, including (but not only) through the values of dignity and respect for patients that these facilities exhibit. Indirectly this suggests that the satisfaction with and quality of services provided by faith-inspired providers may be higher than suggested by survey data. At the same time, patients mention some areas for improvement including in terms of availability of medicines and equipment.
Modelling, Estimation and Visualization of Multivariate Dependence for Risk Management

Dependence modelling and estimation is a key issue in the assessment of portfolio risk. When measuring extreme risk in terms of the Value-at-Risk, the multivariate normal model with linear correlation as its natural dependence measure is by no means an ideal model. We suggest a large class of models and a new dependence function which allows us to capture the complete extreme dependence structure of a portfolio. We also present a simple nonparametric estimation procedure. To show our new method at work we apply it to a financial data set of zero coupon swap rates and estimate the extreme dependence in the data.
A new paradigm for the optimum design of variable angle tow laminates

In this work the authors propose a new paradigm for the optimum design of variable angle tow (VAT) composites. 
They propose a generalisation of a multi-scale two-level (MS2L) optimisation strategy already employed to solve optimisation problems of anisotropic structures characterised by a constant stiffness distribution. In the framework of the MS2L methodology, the design problem is split into two sub-problems. At the first step of the strategy the goal is to determine the optimum distribution of the laminate stiffness properties over the structure, while the second step aims at retrieving the optimum fibres-path in each layer meeting all the requirements provided by the problem at hand. The MS2L strategy relies on: a) the polar formalism for describing the behaviour of the VAT laminate, b) the iso-geometric surfaces for describing the spatial variation of the stiffness properties and c) an hybrid optimisation tool (genetic and gradient-based algorithms) to perform the solution search. The effectiveness of the MS2L strategy is proven through a numerical example on the maximisation of the first buckling factor of a VAT plate subject to both mechanical and manufacturability constraints
Search for a heavy gauge boson decaying to a charged lepton and a neutrino in 1 fb(-1) of pp collisions at root s=7 TeV using the ATLAS detector ATLAS Collaboration

The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (W′W′), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 1.04 fb−1. No excess above Standard Model expectations is observed. A W′W′ with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 2.15 TeV.We acknowledge the support of ANPCyT, Argentina; YerPhl, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; ARTEMIS, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.info:eu-repo/semantics/publishedVersio
Planck intermediate results. XXIV. Constraints on variations in fundamental constants

Any variation in the fundamental physical constants, more particularly in the fine structure constant, α, or in the mass of the electron, me, affects the recombination history of the Universe and cause an imprint on the cosmic microwave background angular power spectra. We show that the Planck data allow one to improve the constraint on the time variation of the fine structure constant at redshift z ∼ 103 by about a factor of 5 compared to WMAP data, as well as to break the degeneracy with the Hubble constant, H0. In addition to α, we can set a constraint on the variation in the mass of the electron, me, and in the simultaneous variation of the two constants. We examine in detail the degeneracies between fundamental constants and the cosmological parameters, in order to compare the limits obtained from Planck and WMAP and to determine the constraining power gained by including other cosmological probes. We conclude that independent time variations of the fine structure constant and of the mass of the electron are constrained by Planck to Δα/α = (3.6 ± 3.7) × 10-3 and Δme/me = (4 ± 11) × 10-3 at the 68% confidence level. We also investigate the possibility of a spatial variation of the fine structure constant. The relative amplitude of a dipolar spatial variation in α (corresponding to a gradient across our Hubble volume) is constrained to be δα/α = (-2.4 ± 3.7) × 10-2. © ESO, 2015
QCD corrections to W + W − production through gluon fusion.

We compute the next-to-leading order (NLO) QCD corrections to the gg→W+W−→l1+ν1l2−ν¯2 process, mediated by a massless quark loop, at the LHC. This process first contributes to the hadroproduction of W+W− at O(αs2), but, nevertheless, has a sizable impact on the total production rate. We find that the NLO QCD corrections to the gg→W+W− process amount to O(50)%, and increase the NNLO QCD cross sections of pp→W+W− by approximately two percent, at both the 8 TeV and 13 TeV LHC. We also compute the NLO corrections to gluonic W+W− production within a fiducial volume used by the ATLAS Collaboration in their 8 TeV measurement of the W+W− production rate and find that the QCD corrections are significantly smaller than in the inclusive case. While the current experimental uncertainties are still too large to make these differences relevant, the observed strong dependence of perturbative corrections on kinematic cuts underscores that extrapolation from a fiducial measurement to the total cross section is an extremely delicate matter, and calls for the direct comparison of fiducial volume measurements with corresponding theoretical computations
Age-related patterns of vigorous-intensity physical activity in youth: the International Children\u27s Accelerometry Database

Physical activity declines during youth but most evidence reports on combined moderate and vigorous-intensity physical activity. We investigated how vigorous-intensity activity varies with age.<br /><br />Cross-sectional data from 24,025 participants (5.0&ndash;18.0 y; from 20 studies in 10 countries obtained 2008&ndash;2010) providing &ge; 1 day accelerometer data (International Children\u27s Accelerometry Database (ICAD)). Linear regression was used to investigate age-related patterns in vigorous-intensity activity; models included age (exposure), adjustments for monitor wear-time and study. Moderate-intensity activity was examined for comparison. Interactions were used to investigate whether the age/vigorous-activity association differed by sex, weight status, ethnicity, maternal education and region.<br /><br />A 6.9% (95% CI 6.2, 7.5) relative reduction in mean vigorous-intensity activity with every year of age was observed; for moderate activity the relative reduction was 6.0% (5.6%, 6.4%). The age-related decrease in vigorous-intensity activity remained after adjustment for moderate activity. A larger age-related decrease in vigorous activity was observed for girls (&minus; 10.7%) versus boys (&minus; 2.9%), non-white (&minus; 12.9% to &minus; 9.4%) versus white individuals (&minus; 6.1%), lowest maternal education (high school (&minus; 2.0%)) versus college/university (ns) and for overweight/obese (&minus; 6.1%) versus healthy-weight participants (&minus; 8.1%). In addition to larger annual decreases in vigorous-intensity activity, overweight/obese individuals, girls and North Americans had comparatively lower average vigorous-intensity activity at 5.0&ndash;5.9 y.<br /><br />Age-related declines in vigorous-intensity activity during youth appear relatively greater than those of moderate activity. However, due to a higher baseline, absolute moderate-intensity activity decreases more than vigorous. Overweight/obese individuals, girls, and North Americans appear especially in need of vigorous-intensity activity promotion due to low levels at 5.0&ndash;5.9 y and larger negative annual differences
Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at sqrt(s) = 13 TeV

A search for single production of vector-like quarks, T and B, decaying into a Z boson and a top or a bottom quark, respectively, is presented. The search is performed using data collected by the CMS experiment at the LHC in proton-proton collisions at sqrt(s) = 13 TeV, corresponding to an integrated luminosity of 2.3 inverse femtobarns. An exotic T quark production mode through the decay of a heavy Z' resonance is also considered. The search is performed in events with a Z boson decaying leptonically, accompanied by a bottom or a top quark decaying hadronically. No excess of events is observed over the standard model background expectation. Products of production cross section and branching fraction for T and B quarks from 1.26 and 0.13 pb are excluded at 95% confidence level for the range of resonance mass considered, which is between 0.7 and 1.7 TeV. Limits on the product of the Z' boson production cross section and branching fraction, with the Z' boson decaying to the Tt final state, are set between 0.31 and 0.13 pb, for Z' boson masses in the range from 1.5 to 2.5 TeV. This is the first search at 13 TeV for single production of vector-like quarks in events with a Z boson decaying leptonically accompanied by boosted jets
A randomized controlled trial reporting functional outcomes of cognitive–behavioural therapy in medication-treated adults with ADHD and comorbid psychopathology

Studies assessing psychological treatment of attention deficit hyperactivity disorder (ADHD) in adults are increasingly reported. However, functional outcomes are often neglected in favour of symptom outcomes. We investigated functional outcomes in 95 adults with ADHD who were already treated with medication and randomized to receive treatment as usual (TAU/MED) or psychological treatment (CBT/MED) using a cognitive–behavioural programme, R&R2ADHD, which employs both group and individual modalities. RATE-S functional outcomes associated with ADHD symptoms, social functioning, emotional control and antisocial behaviour were given at baseline, end of treatment and three-month follow-up. The Total composite score of these scales is associated with life satisfaction. In addition, independent evaluator ratings of clinicians who were blind to treatment arm were obtained on the Clinical Global Impression scale at each time point. CBT/MED showed overall (combined outcome at end of treatment and 3-month follow-up) significantly greater functional improvement on all scales. Post-group treatment effects were maintained at follow-up with the exception of emotional control and the Total composite scales, which continued to improve. The largest treatment effect was for the RATE-S Total composite scale, associated with life satisfaction. CGI significantly correlated with all outcomes except for social functioning scale at follow-up. The study provides further evidence for the effectiveness of R&R2ADHD and demonstrates the importance of measuring functional outcomes. The key mechanism associated with improved functional outcomes is likely to be behavioural control.Susan Young has received consultancy fees, speaker’s fees and/or travel honoraria from Janssen, Eli Lilly, Shire, Novartis and Flynn Pharma, and received research grants from Janssen, Eli Lilly and Shire.

Rotational-vibrational coupling in the BPS Skyrme model of baryons.

We calculate the rotational-vibrational spectrum in the BPS Skyrme model for the hedgehog skyrmion with baryon number one. The resulting excitation energies for the nucleon and delta Roper resonances are slightly above their experimental values. Together with the fact that in the standard Skyrme model these excitation energies are significantly lower than the experimental ones, this provides strong evidence for the conjecture that the inclusion of the BPS Skyrme model is required for a successful quantitative description of physical properties of baryons and nuclei
Measurement of CP observables in $B^{\pm} \to DK^{*\pm}$ decays using two- and four-body D final states

Measurements of CP observables in $B^{\pm} \to DK^{*\pm}$ decays are presented, where D denotes a superposition of $D^0$ and $\overline{D}^0$ meson states. Decays of the D meson to $K^- \pi^+, K^- K^+, \pi^- \pi^+, K^- \pi^+ \pi^- \pi^+$ and $\pi^- \pi^+ \pi^- \pi^+$ are used and the $K^{*\pm}$ meson is reconstructed in the $K_S^0\pi^{\pm}$ final state. This analysis uses a data sample of pp collisions collected with the LHCb experiment, corresponding to integrated luminosities of 1 fb$^{−1}$, 2 fb$^{−1}$ and 1.8 fb$^{−1}$ at centre-of-mass energies $\sqrt{s}$=7 TeV, 8 TeV and 13 TeV, respectively. The sensitivity of the results to the CKM angle $γ$ is discussed
Multi-objective optimization of gate location and processing conditions in injection molding using MOEAs: experimental assessment

The definition of the gate location in injection molding is one of the most important factors in achieving dimensionally accuracy of the parts. This paper presents an optimization methodology for addressing this problem based on a Multi-objective Evolutionary Algorithm (MOEA). The algorithm adopted here is named Reduced Pareto Set Genetic Algorithm (RPSGA) and was used to create a balanced filling pattern using weld line characterization. The optimization approach proposed in this paper is an integration of evolutionary algorithms with Computer-Aided Engineering (CAE) software (Autodesk Moldflow Plastics software). The performance of the proposed optimization methodology was illustrated with an example consisting in the injection of a rectangular part with a non-symmetrical hole. The numerical results were experimentally assessed. Physical meaning was obtained which guaranteed a successful process optimization.This  work  was  supported  by  the  Portuguese  Fundação  para  a  Ciência  e
