TL;DR: In this article, the authors used the SnIa gold data set to compare LCDM (lambda cold dark matter) with ten representative parametrizations of the recent Hubble expansion history H(z).
Abstract: We use the SnIa gold data set to compare LCDM (lambda cold dark matter) with ten representative parametrizations of the recent Hubble expansion history H(z). For the comparison we use two statistical tests: the usual χmin2 and a statistical test that we call the p-test which depends on both the value of χmin2 and the number n of parametrization parameters. The p-test measures the confidence level to which the parameter values corresponding to LCDM are excluded from the viewpoint of the parametrization tested. For example, for a linear equation of state parametrization w(z) = w0+w1z, the LCDM parameter values (w0 = −1, w1 = 0) are excluded at the 75% confidence level. We use a flat prior and Ω0m = 0.3. All parametrizations tested are consistent with the gold data set at their best fit. According to both statistical tests, the worst fits among the ten parametrizations correspond to the Chaplygin gas, the brane world and the Cardassian parametrizations. The best fit is achieved by oscillating parametrizations which can exclude the parameter values corresponding to LCDM at the 85% confidence level. Even though this level of significance does not provide a statistically significant exclusion of LCDM (it is less than 2σ) and does not by itself constitute conclusive evidence for oscillations in the cosmological expansion, when combined with similar independent recent evidence for oscillations coming from the cosmic microwave background and matter power spectra, it becomes an issue worthy of further investigation.

TL;DR: In this article, the muon charge asymmetry in inclusive pp to WX production at 7 TeV was measured with a sample of more than twenty million W to mu nu events, and the statistical precision was greatly improved in comparison to previous measurements.
Abstract: Measurements of the muon charge asymmetry in inclusive pp to WX production at sqrt(s) = 7 TeV are presented. The data sample corresponds to an integrated luminosity of 4.7 inverse femtobarns recorded with the CMS detector at the LHC. With a sample of more than twenty million W to mu nu events, the statistical precision is greatly improved in comparison to previous measurements. These new results provide additional constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10E-3 to 10E-1. These measurements and the recent CMS measurement of associated W + charm production are used together with the cross sections for inclusive deep inelastic ep scattering at HERA in a next-to-leading-order QCD analysis. The determination of the valence quark distributions is improved, and the strange-quark distribution is probed directly through the leading-order process g + s to W + c in proton-proton collisions at the LHC.

TL;DR: In this article, the interaction of individual DNA nucleosides with a carbon nanotube (CNT) in vacuum and in the presence of external gate voltage was investigated and a scheme to discriminate between nucleoside on CNTs based on measurement of electronic features through a local probe such as scanning tunneling spectroscopy.
Abstract: We investigate the interaction of individual DNA nucleosides with a carbon nanotube (CNT) in vacuum and in the presence of external gate voltage. We propose a scheme to discriminate between nucleosides on CNTs based on measurement of electronic features through a local probe such as scanning tunneling spectroscopy. We demonstrate through quantum mechanical calculations that these measurements can achieve 100% efficiency in identifying DNA bases. Our results support the practicality of ultrafast DNA sequencing using electrical measurements.
