{\mu}-MAR: Multiplane 3D Marker based Registration for Depth-sensing
  Cameras

Many applications including object reconstruction, robot guidance, and scene
mapping require the registration of multiple views from a scene to generate a
complete geometric and appearance model of it. In real situations,
transformations between views are unknown an it is necessary to apply expert
inference to estimate them. In the last few years, the emergence of low-cost
depth-sensing cameras has strengthened the research on this topic, motivating a
plethora of new applications. Although they have enough resolution and accuracy
for many applications, some situations may not be solved with general
state-of-the-art registration methods due to the Signal-to-Noise ratio (SNR)
and the resolution of the data provided. The problem of working with low SNR
data, in general terms, may appear in any 3D system, then it is necessary to
propose novel solutions in this aspect. In this paper, we propose a method,
{\mu}-MAR, able to both coarse and fine register sets of 3D points provided by
low-cost depth-sensing cameras, despite it is not restricted to these sensors,
into a common coordinate system. The method is able to overcome the noisy data
problem by means of using a model-based solution of multiplane registration.
Specifically, it iteratively registers 3D markers composed by multiple planes
extracted from points of multiple views of the scene. As the markers and the
object of interest are static in the scenario, the transformations obtained for
the markers are applied to the object in order to reconstruct it. Experiments
have been performed using synthetic and real data. The synthetic data allows a
qualitative and quantitative evaluation by means of visual inspection and
Hausdorff distance respectively. The real data experiments show the performance
of the proposal using data acquired by a Primesense Carmine RGB-D sensor. The
method has been compared to several state-of-the-art methods. The ..
Magnetic moment evolution and spin freezing in doped BaFe2As2

Fe-K β X-ray emission spectroscopy measurements reveal an asymmetric doping dependence of the magnetic moments μbare in electron- and hole-doped BaFe2As2. At low temperature, μbare is nearly constant in hole-doped samples, whereas it decreases upon electron doping. Increasing temperature substantially enhances μbare in the hole-doped region, which is naturally explained by the theoretically predicted crossover into a spin-frozen state. Our measurements demonstrate the importance of Hund’s-coupling and electronic correlations, especially for hole-doped BaFe2As2, and the inadequacy of a fully localized or fully itinerant description of the 122 family of Fe pnictides
Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √S= 8 TeV

A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 fb−1 of proton-proton collisions at √S= 8 TeV collected with the CMS detector at the CERN LHC in 2012. The analysis focuses on searches for a kinematic edge in the invariant mass distribution of the oppositesign same-flavor lepton pair and for final states with an on-shell Z boson. The observations are consistent with expectations from standard model processes and are interpreted in terms of upper limits on the production of supersymmetric particles. © 2015, The Author(s).The Scientific and Technical Research Council of Turkey, and Turkish Atomic Energy Authorit
Automorphisms of Z^d-subshifts of finite type.

Let (S,s) be a Z^d-subshift of finite type. Under a strong irreducibility condition (strong specification), we show that Aut(S) contains any finite group. For Z^d-subshifts of finite type without strong specification, examples show that topological mixing is not sufficient to give any finite group in the automorphism group in general: in particular, End(S) may be an abelian semigroup. For an example of a topologically mixing Z^2-subshift of finite type, the endomorphism semigroup and automorphism group are computed explicitly. This subshift has periodic-point permutations that do not extend to automorphisms
A new inventory for assessing worry in managers: Correlates with job involvement and self-reliance

This work introduces the "Worry Inventory for Managers" (WIM), a 24-item measure of jobrelated worries in managers. A sample of 138 managers responded to the WIM and to measures of pathological worry, job involvement, and self-reliance. Factor analysis of the WIM revealed two facets of job-related worry, namely worry about (1) organizational processes and about (2) work overload. Results indicate that job-related worry shows differential correlations from pathological worry with the three factors of self-reliance (counterdependence, overdependence, and interdependence)
Hierarchical models for service-oriented systems

We present our approach to the denotation and representation of hierarchical graphs: a suitable algebra of hierarchical graphs and two domains of interpretations. Each domain of interpretation focuses on a particular perspective of the graph hierarchy: the top view (nested boxes) is based on a notion of embedded graphs while the side view (tree hierarchy) is based on gs-graphs. Our algebra can be understood as a high-level language for describing such graphical models, which are well suited for defining graphical representations of service-oriented systems where nesting (e.g. sessions, transactions, locations) and linking (e.g. shared channels, resources, names) are key aspects
The VIMOS Public Extragalactic Redshift Survey (VIPERS). Downsizing of the blue cloud and the influence of galaxy size on mass quenching over the last eight billion years

R.T. acknowledges financial support from the European Research Councilthrough grant No. 202686.We use the full VIPERS redshift survey in combination with SDSS-DR7 to explore the relationships between star-formation history (using d4000), stellar mass and galaxy structure, and how these relationships have evolved since z ~ 1. We trace the extents and evolutions of both the blue cloud and red sequence by fitting double Gaussians to the d4000 distribution of galaxies in narrow stellar mass bins, for four redshift intervals over 0 < z < 1. This reveals downsizing in star formation, since the high-mass limit of the blue cloud has retreated steadily from time from ℳ ~ 1011.2 M⊙ at z ~ 0.9 to ℳ ~ 1010.7 M⊙ to the present day. The number density of massive blue-cloud galaxies (ℳ ~ 1011 M⊙, d4000 < 1.55) drops sharply by a factor five between z ~ 0.8 and z ~ 0.5. These galaxies are becoming quiescent at a rate that largely matches  the increase in the numbers of massive passive galaxies seen over this period. We examine the size-mass relation of blue-cloud galaxies,  finding that its high-mass boundary runs along lines of constant ℳ /re or equivalently inferred velocity dispersion. Larger galaxies can continue to form stars to higher stellar masses than smaller galaxies. As  blue-cloud galaxies approach this high-mass limit, entering a narrow diagonal region within the size-mass plane termed the “quenching zone”, they start to be quenched, their d4000 values increasing to push them towards the green valley. In parallel, their structures change, showing higher Sérsic indices and central stellar mass densities. For these galaxies, bulge growth is required for them to reach the high-mass limit of the blue cloud and be quenched by internal mechanisms. The blue-cloud galaxies that are being quenched at z ~ 0.8 lie along the same size-mass relation as present day quiescent galaxies and seem the likely progenitors of today’s S0s.Publisher PDFPeer reviewe
Modeling and Control of a Marine Current Turbine Driven Doubly-Fed Induction Generator

This paper deals with the modeling and the control of a variable speed DFIG-based marine current turbine with and without tidal current speed sensor. The proposed MPPT control strategy relies on the resource and the marine turbine models that were validated by experimental data. The sensitivity of the proposed control strategy is analyzed regarding the swell effect as it is considered as the most disturbing one for the resource model. Tidal current data from the Raz de Sein (Brittany, France) are used to run simulations of a 7.5-kW prototype over various flow regimes. Simulation results are presented and fully analyzedThis work has been funded by Brest Métropole Océan
Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at sqrt(s) = 8 TeV

A search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour-changing neutral current interactions. The data sample corresponds to an integrated luminosity of 19.7 inverse femtobarns recorded by the CMS experiment at the LHC in proton-proton collisions at sqrt(s) = 8 TeV. Final states with three leptons (electrons or muons) and at least one jet are investigated. An events yield compatible with tZq standard model production is observed, and the corresponding cross section is measured to be sigma( p p -&gt; t Z q -&gt; l nu b l+ l- q ) = 10 +8/-7 fb with a significance of 2.4 standard deviations. No presence of flavour-changing neutral current production of tZq is observed. Exclusion limits at 95% confidence level on the branching fractions of a top quark decaying to a Z boson and an up or a charm quark are found to be B( t -&gt; Z u ) &lt; 0.022% and B( t -&gt; Z c ) &lt; 0.049%
Mechanical properties and microstructure of AZ31B magnesium alloy processed by I-ECAP.

Incremental equal channel angular pressing (I-ECAP) is a severe plastic deformation process\ud
used to refine grain size of metals, which allows processing very long billets. As described in the\ud
current article, an AZ31B magnesium alloy was processed for the first time by three different\ud
routes of I-ECAP, namely, A, BC, and C, at 523 K (250 C). The structure of the material was\ud
homogenized and refined to ~5 microns of the average grain size, irrespective of the route used.\ud
Mechanical properties of the I-ECAPed samples in tension and compression were investigated.\ud
Strong influence of the processing route on yield and fracture behavior of the material was\ud
established. It was found that texture controls the mechanical properties of AZ31B magnesium\ud
alloy subjected to I-ECAP. SEM and OM techniques were used to obtain microstructural\ud
images of the I-ECAPed samples subjected to tension and compression. Increased ductility after\ud
I-ECAP was attributed to twinning suppression and facilitation of slip on basal plane. Shear\ud
bands were revealed in the samples processed by I-ECAP and subjected to tension. Tension–\ud
compression yield stress asymmetry in the samples tested along extrusion direction was suppressed\ud
in the material processed by routes BC and C. This effect was attributed to textural\ud
development and microstructural homogenization. Twinning activities in fine- and coarsegrained\ud
samples have also been studied
Non-resonant and electroweak NNLO correction to the e+e− top anti-top threshold.

We determine the NNLO electroweak correction to the   e+e−→bb¯¯W+W−X  production cross section near the top-pair production threshold. The calculation includes non-resonant production of the final state as well as electroweak effects in resonant top anti-top pair production with non-relativistic resummation, and elevates the theoretical prediction to NNNLO QCD plus NNLO electroweak accuracy. We then study the impact of the new contributions on the top-pair threshold scan at a future lepton collider
Proposal of a tangible user interface to increase accessibility in geological exhibitions and the experience of museums

Currently, the museums use different interactive technologies to communicate their exhibitions; however, it turns out that in most cases, information is not accessible to all members of the public. In this paper, we present the design of a tangible user interface to enhance accessibility in geological exhibitions, specifically for the case of visitors with visual impairments, and we also present the study’s results about how to improve the experience of those who visit museums, using this tangible media technology as an exhibitor for samples. The results showed that the interaction with the interface pleased the visitors and that it has application space ithin geological exhibitions.info:eu-repo/semantics/publishedVersio
Socioeconomic status and the 25 × 25 risk factors as determinants of premature mortality: A multicohort study and meta-analysis of 1·7 million men and women

Background: In 2011, WHO member states signed up to the 25 × 25 initiative, a plan to cut mortality due to non-communicable diseases by 25% by 2025. However, socioeconomic factors influencing non-communicable diseases have not been included in the plan. In this study, we aimed to compare the contribution of socioeconomic status to mortality and years-of-life-lost with that of the 25 × 25 conventional risk factors. Methods: We did a multicohort study and meta-analysis with individual-level data from 48 independent prospective cohort studies with information about socioeconomic status, indexed by occupational position, 25 × 25 risk factors (high alcohol intake, physical inactivity, current smoking, hypertension, diabetes, and obesity), and mortality, for a total population of 1 751 479 (54% women) from seven high-income WHO member countries. We estimated the association of socioeconomic status and the 25 × 25 risk factors with all-cause mortality and cause-specific mortality by calculating minimally adjusted and mutually adjusted hazard ratios [HR] and 95% CIs. We also estimated the population attributable fraction and the years of life lost due to suboptimal risk factors. Findings: During 26·6 million person-years at risk (mean follow-up 13·3 years [SD 6·4 years]), 310 277 participants died. HR for the 25 × 25 risk factors and mortality varied between 1·04 (95% CI 0·98-1·11) for obesity in men and 2 ·17 (2·06-2·29) for current smoking in men. Participants with low socioeconomic status had greater mortality compared with those with high socioeconomic status (HR 1·42, 95% CI 1·38-1·45 for men; 1·34, 1·28-1·39 for women); this association remained significant in mutually adjusted models that included the 25 × 25 factors (HR 1·26, 1·21-1·32, men and women combined). The population attributable fraction was highest for smoking, followed by physical inactivity then socioeconomic status. Low socioeconomic status was associated with a 2·1-year reduction in life expectancy between ages 40 and 85 years, the corresponding years-of-life-lost were 0·5 years for high alcohol intake, 0·7 years for obesity, 3·9 years for diabetes, 1·6 years for hypertension, 2·4 years for physical inactivity, and 4·8 years for current smoking. Interpretation: Socioeconomic circumstances, in addition to the 25 × 25 factors, should be targeted by local and global health strategies and health risk surveillance to reduce mortality.

Barriers to childhood cataract services across India. A mixed methods study using the Theoretical Domains Framework (TDF) of behaviour change

Purpose : Early identification and presentation for childhood cataract surgery remains a major challenge in developing countries. The main aim of this study was to identify potential barriers to childhood cataract services from the perspective of parents’ and carers’, as a critical step towards achieving the timely uptake of cataract services.\ud
\ud
Methods : We used a mixed methods explanatory sequential study and interviewed 572 parents/carers attending tertiary hospitals in 8 states across India for their child's cataract surgery. We collected information on barriers to accessing services using a 12-item questionnaire and for each reported barrier, responses recorded on a 5 point scale ranging from “low to high importance”. Based on the quantitative data, in-depth interview questions were prepared and 35 interviews were conducted with randomly selected parents/ carers. Majority of these interviews were conducted at the hospital and /at home for those who did not undergo the surgery. Quantitative questionnaires were completed by the trained interviewer and responses were recorded in a pre-designed format. In-depth interviews were audio taped and transcribed for analysis. Quantitative data were analysed using SPSS 22 while qualitative data were organised with NVivo 11 and a thematic analysis was conducted utilising TDF, an integrative framework of theories.\ud
\ud
Results : From the 831 responses the 5 most important barriers were: economic (40%; n=222); child too young for surgery (17%; n=97); the problem was not felt as severe (16%; n=90); distance (14.5%; n=83) and no one to accompany to the hospital (9.5%; n=54). In addition, being advised by a local ophthalmologist to delay the surgery was also reported (n=16). Domains identified by the TDF included “Knowledge”, “Beliefs about consequences”, “Intentions”, “Goals”, “Decision processes”, “Environmental context and resources”, “Social influences and emotion”. This comprehensive TDF approach enabled us to understand the parents perceived barriers to access services for the children.\ud
\ud
Conclusions : Barriers to accessing childhood cataract services include both practical concerns relating to the family’s socio economic status as well as obstacles from the providers. Mapping out the barriers is necessary to design appropriate intervention for achieving positive behaviour change that can have potential social and economic impact
150 years of macronutrient change in unfertilized UK ecosystems: Observations vs simulations

Understanding changes in plant-soil C, N and P using data alone is difficult due to the linkages between carbon,
nitrogen and phosphorus cycles (C, N and P), and multiple changing long-term drivers (e.g. climate, land-use, and
atmospheric N deposition). Hence, dynamic models are a vital tool for disentangling these drivers, helping us understand the dominant processes and drivers and predict future change. However, it is essential that models are
tested against data if their outputs are to be concluded upon with confidence. Here, a simulation of C, N and P cycles using the N14CP model was compared with time-series observations of C, N and P in soils and biomass from
the Rothamsted Research long-term experiments spanning 150 years, providing an unprecedented temporal integrated test of such a model. N14CP reproduced broad trends in soil organic matter (SOM) C, N and P, vegetation
biomass and N and P leaching. Subsequently, the model was used to decouple the effects of land management
and elevated nitrogen deposition in these experiments. Elevated N deposition over the last 150 years is shown
to have increased net primary productivity (NPP) 4.5-fold and total carbon sequestration 5-fold at the Geescroft
Wilderness experiment, which was re-wilded to woodland in 1886. In contrast, the model predicts that for
cropped grassland conditions at the Park Grass site, elevated N deposition has very little effect on SOM, as increases in NPP are diverted from the soil. More broadly, these results suggest that N deposition is likely to hav
W+W− production at high transverse momenta beyond NLO.

Pair production of W gauge bosons is an important process at the LHC entering many experimental analyses, both as background in new-physics searches or Higgs measurements and as signal in precision studies and tests of the Standard Model. Therefore, accurate predictions for this class of processes are of great interest in order to exploit the full potential of LHC measurements. We use the LoopSim method to combine NLO QCD results for WW and WW + jet, as well as the loop-squared gluon-fusion contribution, to obtain approximate NNLO predictions for WW production. The cross sections are calculated with VBFNLO and include leptonic decays of the W bosons as well as finite-width and off-shell effects. We find that the size of the additional corrections beyond NLO can be significant and well outside of the NLO error bands given by renormalization and factorization scale variation. Applying a jet veto, we observe further negative corrections at NNLO, which we relate to the presence of large Sudakov logarithms
Measurement of the differential branching fraction of the decay Λ0b→Λμ+μ−

The differential branching fraction of the decay Λ0b→Λμ+μ− is measured as a function of the square of the dimuon invariant mass, q2. A yield of 78±12 Λ0b→Λμ+μ− decays is observed using data, corresponding to an integrated luminosity of 1.0\,fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7\,TeV. A significant signal is found in the q2 region above the square of the J/ψ mass, while at lower-q2 values upper limits are set on the differential branching fraction. Integrating the differential branching fraction over q2, while excluding the J/ψ and ψ(2S) regions, gives a branching fraction of $\BF($\Lambda_b^0\rightarrow\Lambda\mu^+\mu^-$)=(0.96\pm 0.16\stat\pm 0.13\syst\pm 0.21 (\mathrm{norm}))\times 10^{-6}$, where the uncertainties are statistical, systematic and due to the normalisation mode, $$\Lambda_b^0\rightarrow J/psi\Lambda$, respectively
Evidence for two distinct anisotropies in the oxypnictide
  superconductors SmFeAsO_(0.8)F_(0.2) and NdFeAsO_(0.8)F_(0.2)

Single crystals of the oxypnictide superconductors SmFeAsO_(0.8)F_(0.2) and
NdFeAsO_(0.8)F_(0.2) with T_c in the range of 44 K to 48 K were investigated by
torque magnetometry. An analysis of the data in terms of a recently proposed
model for the anisotropic magnetization in the superconducting state, treating
the penetration depth anisotropy differently than the upper critical field
anisotropy, provides evidence that in the oxypnictide superconductors two
distinct anisotropies are present. As a result the penetration depth anisotropy
differs significantly in magnitude and in temperature dependence from the upper
critical field anisotropy, analogous to MgB_2 but with a reversed sign of
slope. This scenario strongly suggests a new multi-band mechanism in the novel
class of oxypnictide high-temperature superconductors.Comment: published online in J. Supercond. Nov. Mag
Band gap control via tuning of inversion degree in CdIn$_2$S$_4$ spinel

Based on theoretical arguments we propose a possible route for controlling
the band-gap in the promising photovoltaic material CdIn$_2$S$_4$. Our
\textit{ab initio} calculations show that the experimental degree of inversion
in this spinel (fraction of tetrahedral sites occupied by In) corresponds
approximately to the equilibrium value given by the minimum of the theoretical
inversion free energy at a typical synthesis temperature. Modification of this
temperature, or of the cooling rate after synthesis, is then expected to change
the inversion degree, which in turn sensitively tunes the electronic band-gap
of the solid, as shown here by accurate screened hybrid functional
calculations.Comment: In press in Applied Physics Letters (2012); 4 pages, 2 figures, 1
