SATURNʼS INNER SATELLITES: ORBITS, MASSES, AND THE CHAOTIC MOTION OF ATLAS FROM NEW CASSINI IMAGING OBSERVATIONS

International audienceWe present numerically derived orbits and mass estimates for the inner Saturnian satellites, Atlas, Prometheus, Pandora, Janus, and Epimetheus from a fit to 2580 new Cassini Imaging Science Subsystem astrometric observations spanning 2004 February to 2013 August. The observations are provided as machine-readable and Virtual Observatory tables. We estimate GM Atlas = (0.384 ± 0.001) × 10 −3 km 3 s −2 , a value 13% smaller than the previously published estimate but with an order of magnitude reduction in the uncertainty. We also find GM Prometheus = (10.677 ± 0.006) × 10 −3 km 3 s −2 , GM Pandora = (9.133 ± 0.009) × 10 −3 km 3 s −2 , GM Janus = (126.51 ± 0.03) × 10 −3 km 3 s −2 , and GM Epimetheus = (35.110 ± 0.009) × 10 −3 km 3 s −2 , consistent with previously published values, but also with significant reductions in uncertainties. We show that Atlas is currently librating in both the 54:53 co-rotation-eccentricity resonance (CER) and the 54:53 inner Lindblad (ILR) resonance with Prometheus, making it the latest example of a coupled CER-ILR system, in common with the Saturnian satellites Anthe, Aegaeon, and Methone, and possibly Neptuneʼs ring arcs. We further demonstrate that Atlasʼs orbit is chaotic, with a Lyapunov time of ∼10 years, and show that its chaotic behavior is a direct consequence of the coupled resonant interaction with Prometheus, rather than being an indirect effect of the known chaotic interaction between Prometheus and Pandora. We provide an updated analysis of the second-order resonant perturbations involving Prometheus, Pandora, and Epimetheus based on the new observations, showing that these resonant arguments are librating only when Epimetheus is the innermost of the co-orbital pair, Janus and Epimetheus. We also find evidence that the known chaotic changes in the orbits of Prometheus and Pandora are not confined to times of apse anti-alignment
Working conditions of school and teacher training in science : a study with teachers of biology of Bahia, Brazil

We identify what are the influences of working conditions for school science teachers training that is sensitive to
intercultural dialogue. The study was conducted in 2009, based on semi-structured interview, and involved nine
teachers of biology at Bahia, Brazil. The results indicate that several factors of the schools where the teachers
interviewed work interfere negatively in their teaching and their training with regard to intercultural dialogue.
Mobilizations are necessary to obtain changes in this way, especially by teachers, schools, universities and decision
makers in the field of public policy education.CIEC - Centro de Investigação em Estudos da Criança, UM (UI 317 da FCT
The thermal scalar and random walks in AdS3 and BTZ

We analyze near-Hagedorn thermodynamics of strings in the WZW AdS(3) model. We compute the thermal spectrum of all primaries and find the thermal scalar explicitly in the string spectrum using CFT twist techniques. Then we use the link to the Euclidean WZW BTZ black hole and write down the Euclidean BTZ spectrum. We give a Hamiltonian interpretation of the thermal partition function of angular orbifolds where we find a reappearance of discrete states that dominate the partition function. Using these results, we discuss the nature of the thermal scalar in the WZW BTZ model. As a slight generalization of the angular orbifolds, we discuss the AdS(3) string gas with a non-zero chemical potential corresponding to angular momentum around the spatial cigar. For this model as well, we determine the thermal spectrum and the Hagedorn temperature as a function of chemical potential. Finally the nature of alpha' corrections to the AdS(3) thermal scalar action is analyzed and we find the random walk behavior of highly excited strings in this particular AdS(3) background

Linear and weakly nonlinear magnetoconvection in a porous medium with a thermal nonequilibrium model

Two-dimensional magnetoconvection in a layer of Brinkman porous medium with local thermal nonequilibrium (LTNE) model is investigated by performing both linear and weakly nonlinear stability analyses. Condition for the occurrence of stationary and oscillatory convection is obtained in the case of linear stability analysis. It is observed that the presence of magnetic field is to introduce oscillatory convection once the Chandrasekhar number exceeds a threshold value if the ratio of the magnetic diffusivity to the thermal diffusivity is sufficiently small. Besides, asymptotic solutions for both small and large values of the inter-phase heat transfer coefficient are presented for the steady case. A weakly nonlinear stability analysis is performed by constructing a system of nonlinear autonomous ordinary differential equations. It is observed that subcritical steady convection is possible for certain choices of physical parameters. Heat transport is calculated in terms of Nusselt number. Increasing the value of Chandrasekhar number, inter-phase heat transfer coefficient and the inverse Darcy number is to decrease the heat transport, while increasing the ratio of the magnetic diffusivity to the thermal diffusivity and the porosity modified conductivity ratio shows an opposite kind of behavior on the heat transfer
Cystatin C and Cardiovascular Disease: A Mendelian Randomization Study

© 2016 The Authors Background Epidemiological studies show that high circulating cystatin C is associated with risk of cardiovascular disease (CVD), independent of creatinine-based renal function measurements. It is unclear whether this relationship is causal, arises from residual confounding, and/or is a consequence of reverse causation. Objectives The aim of this study was to use Mendelian randomization to investigate whether cystatin C is causally related to CVD in the general population. Methods We incorporated participant data from 16 prospective cohorts (n = 76,481) with 37,126 measures of cystatin C and added genetic data from 43 studies (n = 252,216) with 63,292 CVD events. We used the common variant rs911119 in CST3 as an instrumental variable to investigate the causal role of cystatin C in CVD, including coronary heart disease, ischemic stroke, and heart failure. Results Cystatin C concentrations were associated with CVD risk after adjusting for age, sex, and traditional risk factors (relative risk: 1.82 per doubling of cystatin C; 95% confidence interval [CI]: 1.56 to 2.13; p = 2.12 × 10−14). The minor allele of rs911119 was associated with decreased serum cystatin C (6.13% per allele; 95% CI: 5.75 to 6.50; p = 5.95 × 10−211), explaining 2.8% of the observed variation in cystatin C. Mendelian randomization analysis did not provide evidence for a causal role of cystatin C, with a causal relative risk for CVD of 1.00 per doubling cystatin C (95% CI: 0.82 to 1.22; p = 0.994), which was statistically different from the observational estimate (p = 1.6 × 10−5). A causal effect of cystatin C was not detected for any individual component of CVD. Conclusions Mendelian randomization analyses did not support a causal role of cystatin C in the etiology of CVD. As such, therapeutics targeted at lowering circulating cystatin C are unlikely to be effective in preventing CVD
Are MNCs norm entrepreneurs or followers? The changing relationship between host country institutions and MNC HRM practices

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

Epiblast-specific loss of HCF-1 leads to failure in anterior-posterior axis specification.

Mammalian Host-Cell Factor 1 (HCF-1), a transcriptional co-regulator, plays important roles during the cell-division cycle in cell culture, embryogenesis as well as adult tissue. In mice, HCF-1 is encoded by the X-chromosome-linked Hcfc1 gene. Induced Hcfc1(cKO/+) heterozygosity with a conditional knockout (cKO) allele in the epiblast of female embryos leads to a mixture of HCF-1-positive and -deficient cells owing to random X-chromosome inactivation. These embryos survive owing to the replacement of all HCF-1-deficient cells by HCF-1-positive cells during E5.5 to E8.5 of development. In contrast, complete epiblast-specific loss of HCF-1 in male embryos, Hcfc1(epiKO/Y), leads to embryonic lethality. Here, we characterize this lethality. We show that male epiblast-specific loss of Hcfc1 leads to a developmental arrest at E6.5 with a rapid progressive cell-cycle exit and an associated failure of anterior visceral endoderm migration and primitive streak formation. Subsequently, gastrulation does not take place. We note that the pattern of Hcfc1(epiKO/Y) lethality displays many similarities to loss of β-catenin function. These results reveal essential new roles for HCF-1 in early embryonic cell proliferation and development
Search for Heavy Narrow Dilepton Resonances in Pp Collisions at √s = 7 TeV and √s = 8 TeV

An updated search for heavy narrow resonances decaying to muon or electron pairs using the CMS detector is presented. Data samples from pp collisions at √s = 7 TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1 fb[superscript −1], respectively, are combined. No evidence for a heavy narrow resonance is observed. The analysis of the combined data sets excludes, at 95% confidence level, a Sequential Standard Model Z[' over SSM] resonance lighter than 2590 GeV, a superstring-inspired Z[' over ψ] lighter than 2260 GeV, and Kaluza–Klein gravitons lighter than 2390 (2030) GeV, assuming that the coupling parameter k/[bar over M][subscript Pl] is 0.10 (0.05). These are the most stringent limits to date.United States. Dept. of EnergyNational Science Foundation (U.S.
Measurement of the $t\overline{t}$ production cross section in the e$\mu$ channel in proton-proton collisions at $\sqrt{s}$ = 7 and 8 TeV

The inclusive cross section for top quark pair production is measured in proton- proton collisions at $\sqrt{s}$ = 7 and 8TeV, corresponding to 5.0 and 19.7fb$^{−1}$, respectively, with the CMS experiment at the LHC. The cross sections are measured in the electron-muon channel using a binned likelihood fit to multi-differential final state distributions related to identified b quark jets and other jets in the event. The measured cross section values are 173.6 ${\pm}$ 2.1 (stat)$^{+ 4.5}_{− 4.0}$ (syst) ${\pm}$ 3.8 (lumi) pb at $\sqrt{s}$ = 7 TeV,  and 244.9 ${\pm}$ 1.4 (stat)$^{+ 6.3}_{− 5.5}$ (syst) ${\pm}$ 6.4 (lumi) pb at $\sqrt{s}$ = 8 TeV, in good agreement with QCD calculations at next-to-next-to-leading-order accuracy. The ratio of the cross sections measured at 7 and 8 TeV is determined, as well as cross sections in the fiducial regions defined by the acceptance requirements on the two charged leptons in the final state. The cross section results are used to determine the top quark pole mass via the dependence of the theoretically predicted cross section on the mass, giving a best result of 173.8$^{+1.7}_{−1.8}$ GeV. The data at $\sqrt{s}$ = 8 TeV are also used to set limits, for two neutralino mass values, on the pair production of supersymmetric partners of the top quark with masses close to the top quark mass
Learning what matters - Sampling interesting patterns

In the field of exploratory data mining, local structure in data can be
described by patterns and discovered by mining algorithms. Although many
solutions have been proposed to address the redundancy problems in pattern
mining, most of them either provide succinct pattern sets or take the interests
of the user into account-but not both. Consequently, the analyst has to invest
substantial effort in identifying those patterns that are relevant to her
specific interests and goals. To address this problem, we propose a novel
approach that combines pattern sampling with interactive data mining. In
particular, we introduce the LetSIP algorithm, which builds upon recent
advances in 1) weighted sampling in SAT and 2) learning to rank in interactive
pattern mining. Specifically, it exploits user feedback to directly learn the
parameters of the sampling distribution that represents the user's interests.
We compare the performance of the proposed algorithm to the state-of-the-art in
interactive pattern mining by emulating the interests of a user. The resulting
system allows efficient and interleaved learning and sampling, thus
user-specific anytime data exploration. Finally, LetSIP demonstrates favourable
trade-offs concerning both quality-diversity and exploitation-exploration when
compared to existing methods.Comment: PAKDD 2017, extended versio

Published by Elsevier Ltd.Artificial turf is successfully utilized around the world for many sports and many levels of performance and competition requirement. Quality assurance systems for elite and community level demand effective maintenance programmes to ensure adequate play performance, with increasing regulation and auditing in the UK. Past research is, however, very limited in this important aspect of artificial turf science. Practical experience is relied upon to plan for and deliver a range of maintenance techniques to sweep, clean, decompact, replace and repair artificial turf carpets and infills. Validation of these techniques has yet to be comprehensively undertaken and reported. The authors have collaborated with an industry maintenance provider over a 4 year period focussed on measuring the effectiveness of common maintenance practice. This paper aims to present an overview of the data and outcomes of detailed studies into power-sweeping, decompaction, and decontamination, in light of temporal pitch monitoring of changes in play performance. The field data provide a unique insight into the short-term and long-term benefits of these intervention processes. The data permit quantitative analysis of key issues such as: the build-up of contamination that clogs infill and can lead to surface flooding; compaction of infill under player loading and how this affects the system hardness; and how loss of fibre resilience influences ball roll behaviour. The results demonstrate that, for example, the monthly power-brushing of a surface may effectively reduce the rate of build-up of contamination by more than 1% per year. This alone can potentially add several years' playing life to a sand-filled pitch before costly deep cleaning or removal of the contaminated infill is required
The curious case of HD 41248. A pair of static signals buried behind red noise

All rights reserved.Gaining a better understanding of the effects of stellar-induced radial velocity noise is critical for the future of exoplanet studies since the discovery of the lowest-mass planets using this method will require us to go below the intrinsic stellar noise limit. An interesting test case in this respect is that of the southern solar analog HD 41248. The radial velocity time series of this star has been proposed to contain either a pair of signals with periods of around 18 and 25 days, which could be due to a pair of resonant super-Earths, or a single and varying 25 day signal that could arise due to a complex interplay between differential rotation and modulated activity. In this work, we build up more evidence for the former scenario, showing that the signals are still clearly significant, even after more than 10 yr of observations, and they likely do not change in period, amplitude, or phase as a function of time, the hallmarks of static Doppler signals. We show that over the last two observing seasons, this star was more intrinsically active and the noise reddened, highlighting why better noise models are needed to find the lowest amplitude signals, in particular, models that consider noise correlations. This analysis shows that there is still sufficient evidence for the existence of two super-Earths on the edge of, or locked into, a 7:5 mean motion resonance orbiting HD 41248
Dynamic photoluminescence lifetime imaging for injectiondependent lifetime measurements

We investigate the impact of an injection-dependent carrier lifetime in crystalline silicon on dynamic photoluminescence lifetime imaging (dynamic PLI). Although the dynamic lifetime approach is a technique that evaluates the time-dependence of a quantity proportional to the excess carrier density, it is only weakly influenced by the injection-level dependence of the lifetime. The reason for the little impact is the fact that the evaluation of dynamic PLI measurements does not only involve the decay of the carrier density, as it is common for photoconductance decay measurements, but also the increase of the carrier density directly after switching on the excitation source. In this contribution, we present injection-dependent lifetime measurements that are acquired with the camera-based dynamic PLI technique. We find that the deviation of the actual steady-state carrier lifetime from the lifetime obtained with dynamic PLI is less than 20 % for a wide range of measurement conditions.State of Lower SaxonyGerman Federal Ministry for the Environment, Nature Conservation, and Nuclear Safet
Supporting older and younger adults??? memory for recent everyday events: A prospective sampling study using SenseCam

Participants used SenseCam to prospectively sample events from a typical week, which they recalled two weeks later. Recall was cued by a self-generated title only (control condition), by the title and forward-order SenseCam images, or by the title and random-order SenseCam images. In the control condition, older and younger adults??? memories were comparably episodic, but older adults recalled more semantic details. Both forward- and random-order SenseCam images were associated with increased episodic and semantic recall in both groups, and there was a small but significant effect of temporal order favouring the forward-order condition. These findings suggest that SenseCam is effective in supporting retrieval of memory for recent events, and the results of the temporal order manipulation also shed light on the mechanism of SenseCam???s effect
