Modeling the Cold Formability of Dualphase Steels on Different Length Scales

AbstractModern multiphase steels contain constituents of distinctive mechanical properties, so that they develop strong gradients in the local strain distribution during forming operations and this strongly promotes the microstructural damage evolution. Consequently, the material’ resistance against ductile crack initiation sets the limits of cold formability and these can even be reached without any macroscopic necking phenomena. The modified Bai Wierzbicki (MBW) model has been proven the capability of providing an impressive accuracy of simulation results when applied to stretch forming tests as it describes ductile crack initiation and propagation. The consideration of the third invariant of the stress deviator on plasticity and ductile failure is a key factor for the model’ high accuracy, but due to its phenomenological character its applicability for materials design is currently not given. Furthermore, the quantity of material parameters is so high that an industrial application of this model cannot be expected. Therefore the paper presents an alternative approach for parameter calibration relying on virtual experiments on representative volume elements, where the plastic strain localization theory is applied without any other damage model
Minimum average-case queries of q+1-ary search game with small sets

AbstractGiven a search space S={1,2,…,n}, an unknown element x∗∈S and fixed integers ℓ≥1 and q≥1, a q+1-ary ℓ-restricted query is of the following form: which one of the set {A0,A1,…,Aq} is the x∗ in?, where (A0,A1,…,Aq) is a partition of S and |Ai|≤ℓ for i=1,2,…,q. The problem of finding x∗ from S with q+1-ary size-restricted queries is called as a q+1-ary search game with small sets. In this paper, we consider sequential algorithms for the above problem, and establish the minimum number of average-case sequential queries when x∗ satisfies the uniform distribution on S
Shear in Reinforced and Unreinforced Masonry: Response, Design and Construction

AbstractThis paper describes the vulnerability of masonry under shear; first the mechanisms of in-plane and out-of-plane shear performance of masonry are reviewed; both the unreinforced and lightly reinforced masonry wall systems are considered. Factors affecting the response of unreinforced and reinforced masonry to shear are described and the effect of the variability of those factors to the failure mode of masonry shear walls is also discussed. Some critique is provided on the existing design provisions in various masonry standards
Search for invisible decays of a Higgs boson using vector-boson fusion in pp collisions at √s = 8 TeV with the ATLAS detector

A search for a Higgs boson produced via vector-boson fusion and decaying into invisible particles is presented, using 20.3 fb[superscript −1] of proton-proton collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the LHC. For a Higgs boson with a mass of 125 GeV, assuming the Standard Model production cross section, an upper bound of 0.28 is set on the branching fraction of H → invisible at 95% confidence level, where the expected upper limit is 0.31. The results are interpreted in models of Higgs-portal dark matter where the branching fraction limit is converted into upper bounds on the dark-matter-nucleon scattering cross section as a function of the dark-matter particle mass, and compared to results from the direct dark-matter detection experiments.United States.

15q11.2 CNV affects cognitive, structural and functional correlates of dyslexia and dyscalculia

Several copy number variants have been associated with neuropsychiatric disorders and these variants have been shown to also influence cognitive abilities in carriers unaffected by psychiatric disorders. Previously, we associated the 15q11.2(BP1-BP2) deletion with specific learning disabilities and a larger corpus callosum. Here we investigate, in a much larger sample, the effect of the 15q11.2(BP1-BP2) deletion on cognitive, structural and functional correlates of dyslexia and dyscalculia. We report that the deletion confers greatest risk of the combined phenotype of dyslexia and dyscalculia. We also show that the deletion associates with a smaller left fusiform gyrus. Moreover, tailored functional magnetic resonance imaging experiments using phonological lexical decision and multiplication verification tasks demonstrate altered activation in the left fusiform and the left angular gyri in carriers. Thus, by using convergent evidence from neuropsychological testing, and structural and functional neuroimaging, we show that the 15q11.2(BP1-BP2) deletion affects cognitive, structural and functional correlates of both dyslexia and dyscalculia
A case study investigating the impact of the London 2012 Olympic and Paralympic Games on participation in two non-traditional English sports, Judo and Fencing

This is an Accepted Manuscript of an article published by Taylor & Francis in Leisure Studies on 30th April 2015, available online: http://www.tandfonline.com/10.1080/02614367.2015.1035314The hosting of the London 2012 Olympic and Paralympic Games (LOPG) brought with it detailed legacy plans aiming to ‘Inspire a Generation’. The idea that hosting a sports mega-event will encourage the host population to engage in more physical activity is commonly used by governments to justify the large investments they make. The aim of this research paper was to investigate the impact that hosting the 2012 Games had on grass-root sports participation within the host nation. This paper focuses on two non-traditional English sports, Fencing and Judo and investigated the changes in mass sports participation. The membership rate analysis of our sample highlighted an overall increase in participation between 2007 and 2013, in both Judo and Fencing. The data gathered from the interviews with the head office staff at the National Governing Bodies (NGBs) and local club coaches suggested that the grass-root participation programmes were the most effective way of increasing participation, rather than the reliance, solely on the inspiration effect from hosting the LOPG itself. The study highlighted the importance of strengthening communication between local voluntary clubs and the NGB, to ensure sports could promote themselves and capitalise on this global sporting phenomenon, which provided unprecedented media coverage and opportunities for these non-traditional sports. This case study provides initial results relating to the effect that a major international multi-sport event can have in the development of non-traditional sports in the host population, in terms of membership variations, participation programmes and organisational dynamics
PKS2005-489 at VHE: four years of monitoring with HESS and simultaneous multi-wavelength observations

VHE observations of PKS 2005-489 were made with HESS from 2004 through 2007, together with three simultaneous multi-wavelength campaigns performed with XMM-Newton and RXTE in 2004 and 2005. A strong VHE signal, ~17sigma total, is detected during the four years of HESS observations (90.3 hrs live time). The integral flux above the average analysis threshold of 400 GeV is ~3% of the Crab and varies weakly on time-scales from days to years. At X-ray energies the flux is observed to vary by more than an order of magnitude between 2004 and 2005. Strong changes in the X-ray spectrum (DeltaGamma~0.7) are also observed, which appear to be mirrored in the VHE band. The SED of PKS 2005-489, constructed for the first time with contemporaneous data on both humps, shows significant evolution. The large flux variations in the X-ray band, coupled with weak or no variations in the VHE band and a similar spectral behavior, suggest the emergence of a new, separate, harder emission component in September 2005.F.

Selective effect of early social experience on the development of eye gaze processing

Eye gaze is a key channel of non-verbal communication in humans [1, 2 and 3]. Eye contact with others is present from birth [4], and eye gaze processing is crucial for social learning and adult-infant communication [5, 6 and 7]. However, little is known about the effect of selectively different experience of eye contact and gaze communication on early social and communicative development. To directly address this question, we assessed 14 sighted infants of blind parents (SIBPs) longitudinally at 6–10 and 12–16 months. Face scanning [8] and gaze following [7 and 9] were assessed using eye tracking. In addition, naturalistic observations were made when the infants were interacting with their blind parent and with an unfamiliar sighted adult. Established measures of emergent autistic-like behaviors [10] and standardized tests of cognitive, motor, and linguistic development [11] were also collected. These data were then compared with those obtained from a group of infants of sighted parents. Despite showing typical social skills development overall, infants of blind parents allocated less attention to adult eye movements and gaze direction, an effect that increased between 6–10 and 12–16 months of age. The results suggest that infants adjust their use of adults’ eye gaze depending on gaze communication experience from early in life. The results highlight that human functional brain development shows selective experience-dependent plasticity adaptive to the individual’s specific social environment
Characterising one-to-one conservatoire teaching: Some implications of a quantitative analysis

Despite the significant recent growth in research relating to instrumental, vocal and composition tuition in higher education, little is known about the diversity of approaches that characterise one-to-one teaching in the Conservatoire, and what counts as optimal practice for educating 21st-century musicians.  Through analysis of video-recorded one-to-one lessons that draws on a 'bottom up' methodology for characterising pedagogical practices (Taylor, 2012; Taylor et al, 2012), this paper provides empirical evidence about the nature of one-to-one pedagogy in one Australian institution. The research aims (1) to enable a better understanding of current one-to-one conservatoire teaching; and (2) to build and improve upon existing teaching practice using authentic insights gained through systematic investigation. The authors hope the research will lead to a better understanding of the diversity and efficacy of the pedagogical practice within the specific context in which the study was conducted, and beyond, to Conservatoire pedagogy generally."Arts, Education & Law Group, Queensland ConservatoriumFull Tex
Relativistic description of 3He(e,e'p)2H

The relativistic distorted-wave impulse approximation is used to describe the 3He(e, e′ p)2H process. We describe the 3He nucleus within the adiabatic hyperspherical expansion method with realistic nucleon-nucleon interactions. The overlap between the 3He and the deuteron wave functions can be accurately computed from a three-body calculation. The nucleons are described by solutions of the Dirac equation with scalar and vector (S–V) potentials. The wave function of the outgoing proton is obtained by solving the Dirac equation with a S–V optical potential fitted to elastic proton scattering data on the residual nucleus. Within this theoretical framework, we compute the cross section of the reaction and other observables like the transverse-longitudinal asymmetry, and compare them with the available experimental data measured at JLab
Job design, employment practices and well-being: :
                    a systematic review of intervention studies

We investigated the role of other employment practices, either as instruments for job redesign or as instruments that augment job redesign. Our primary outcome was well-being. Where studies also assessed performance, we considered performance as an outcome. We reviewed 33 intervention studies. We found that well-being and performance may be improved by: training workers to improve their own jobs; training coupled with job redesign; and system wide approaches that simultaneously enhance job design and a range of other employment practices. We found insufficient evidence to make any firm conclusions concerning the effects of training managers in job redesign and that participatory approaches to improving job design have mixed effects. Successful implementation of interventions was associated with worker involvement and engagement with interventions, managerial commitment to interventions and integration of interventions with other organisational systems. Practitioner Summary: Improvements in well-being and performance may be associated with system-wide approaches that simultaneously enhance job design, introduce a range of other employment practices and focus on worker welfare. Training may have a role in initiating job redesign or augmenting the effects of job design on well-being
Are MNCs norm entrepreneurs of followers? :
                    The changing relationship between host country institutions and MNC HRM practices.

This is the Accepted Manuscript of an article published by Taylor & Francis Group in The International Journal of Human Resource Management on 4 July 2017, available online at: https://www.tandfonline.com/doi/full/10.1080/09585192.2016.1277365. Under embargo until 11 July 2018.Rooted in the literature on comparative capitalism, we examine the effects of host country institutions on the intra-organizational practices of multinational corporations (MNCs), using transnational level survey data, exploring change over time. We found that the less comprehensive institutional mediation of the Liberal Market Economies correlated with greater diversity and a more pronounced difference between domestic firms and foreign MNCs. However, rather than being the predicted norm entrepreneurs, MNCs tended to follow the lead of local firms in adjusting HRM policies and practices towards liberalization. Those most prone to challenging existing orders were in industries facing particular crises of competitiveness. Finally, we found that single regulatory features rather than complex assemblies of institutions exerted particularly strong effects on the individual firms??? practices encompassed in this study
An eight-dimensional approach to G(2) manifolds

We develop a systematic approach to G_(2) holonomy manifolds with an SU(2) × SU(2) isometry using maximal eight-dimensional gauged supergravity to describe D6-branes wrapped on deformed three-spheres. A quite general metric ansatz that generalizes the celebrated Bryant–Salamon metric involves nine functions. We show that only six of them are the independent ones and derive the general first order system of differential equations that they obey. As a byproduct of our analysis, we generalize the notion of the twist that relates the spin and gauge connections in a way that involves non-trivially the scalar fields
Tracking pan-continental trends in environmental contamination&nbsp;using sentinel raptors—what types of samples should we use?

Biomonitoring using birds of prey as sentinel species has been mooted as a way to evaluate the success of European Union directives that are designed to protect people and the environment across Europe from industrial contaminants and pesticides. No such pan-European evaluation currently exists. Coordination of such large scale monitoring would require harmonisation across multiple countries of the types of samples collected and analysed-matrices vary in the ease with which they can be collected and the information they provide. We report the first ever pan-European assessment of which raptor samples are collected across Europe and review their suitability for biomonitoring. Currently, some 182 monitoring programmes across 33 European countries collect a variety of raptor samples, and we discuss the relative merits of each for monitoring current priority and emerging compounds. Of the matrices collected, blood and liver are used most extensively for quantifying trends in recent and longer-term contaminant exposure, respectively. These matrices are potentially the most effective for pan-European biomonitoring but are not so widely and frequently collected as others. We found that failed eggs and feathers are the most widely collected samples. Because of this ubiquity, they may provide the best opportunities for widescale biomonitoring, although neither is suitable for all compounds. We advocate piloting pan-European monitoring of selected priority compounds using these matrices and developing read-across approaches to accommodate any effects that trophic pathway and species differences in accumulation may have on our ability to track environmental trends in contaminants.© The Author(s) 2016 - Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made
An unusual π* shape resonance in the near-threshold photoionization of S₁ para-difluorobenzene

Previously reported dramatic changes in photoelectron angular distributions (PADs) as a function of photoelectron kinetic energy following the ionization of S₁p-difluorobenzene are shown to be explained by a shape resonance in the b₂g symmetry continuum. The characteristics of this resonance are clearly demonstrated by a theoretical multiple-scattering treatment of the photoionization dynamics. New experimental data are presented which demonstrate an apparent insensitivity of the PADs to both vibrational motion and prepared molecular alignment, however, the calculations suggest that strong alignment effects may nevertheless be recognized in the detail of the comparison with experimental data. The apparent, but unexpected, indifference to vibrational excitation is rationalized by considering the nature of the resonance. The correlation of this shape resonance in the continuum with a virtual π* antibonding orbital is considered. Because this orbital is characteristic of the benzene ring, the existence of similar resonances in related substituted benzenes is discussed.K.L.R. acknowledges EPSRC for funding Grant Nos.

3D-HST+CANDELS : the evolution of the galaxy size-mass distribution since z=3

Spectroscopic + photometric redshifts, stellar mass estimates, and rest-frame colors from the 3D-HST survey are combined with structural parameter measurements from CANDELS imaging to determine the galaxy size-mass distribution over the redshift range 0 < z < 3. Separating early-and late-type galaxies on the basis of star-formation activity, we confirm that early-type galaxies are on average smaller than late-type galaxies at all redshifts, and we find a significantly different rate of average size evolution at fixed galaxy mass, with fast evolution for the early-type population, R-eff proportional to (1 + z)(-1.48), and moderate evolution for the late-type population, R-eff proportional to (1 + z)(-0.75). The large sample size and dynamic range in both galaxy mass and redshift, in combination with the high fidelity of our measurements due to the extensive use of spectroscopic data, not only fortify previous results but also enable us to probe beyond simple average galaxy size measurements. At all redshifts the slope of the size-mass relation is shallow, R-eff proportional to M-*(0.22) , for late-type galaxies with stellar mass >3 x 10(9) M-circle dot, and steep, R-eff proportional to M-*(0.75), for early-type galaxies with stellar mass >2 x 10(10) M-circle dot. The intrinsic scatter is less than or similar to 0.2 dex for all galaxy types and redshifts. For late-type galaxies, the logarithmic size distribution is not symmetric but is skewed toward small sizes: at all redshifts and masses, a tail of small late-type galaxies exists that overlaps in size with the early-type galaxy population. The number density of massive (similar to 10(11)M(circle dot)), compact (R-eff < 2 kpc) early-type galaxies increases from z = 3 to z 1.5-2 and then strongly decreases at later cosmic times
Comparing 2D pictures with 3D replicas for the digital preservation and analysis of tangible heritage

In this paper, we present two experiments designed to compare 2D digital pictures and 3D digital replicas of artifacts, to understand how differently these media facilitate the perception and understanding of our past. Archeologists and museum experts have commonly used 2D digital pictures to preserve and study artifacts. Recently, these scholars have also started to use 3D digital archives for their studies. Yet, we still need to determine how these two formats (2D vs. 3D) affect the perception of our past. Results of our experiments point to 3D digital replicas of artifacts as more effective means to digitally preserve tangible cultural heritage, since 3D multi-visualization augments the perception of physical characteristics of the artifacts allowing a more embodied experience with these objects. Our experiments also suggest that multi-visualization (i.e., point-cloud, mesh, and color information) helps the viewers to overcome their personal conceptualization of specific objects
Transformational leadership and employee voice behavior : a Pygmalion mechanism.

We theorized and examined a Pygmalion perspective beyond those proposed in past studies in the relationship between transformational leadership and employee voice behavior. Specifically, we proposed that transformational leadership influences employee voice through leaders' voice expectation and employees' voice role perception (i.e., Pygmalion mechanism). We also theorized that personal identification with transformational leaders influences the extent to which employees internalize leaders' external voice expectation as their own voice role perception. In a time‐lagged field study, we found that leaders' voice expectation and employees' voice role perception (i.e., the Pygmalion process) mediate the relationship between transformational leadership and voice behavior. In addition, we found transformational leadership strengthens employees' personal identification with the leader, which in turn, as a moderator, amplifies the proposed Pygmalion process. Theoretical and practical implications are discussed
