TL;DR: In this article, the authors explore the warm inflation scenario theoretical predictions looking at two different dissipative regimes for several representative primordial potentials and show that warm inflation is able to decrease the tensor-to-scalar ratio value.
Abstract: We explore the warm inflation scenario theoretical predictions looking at two different dissipative regimes for several representative primordial potentials As it is well known, warm inflation is able to decrease the tensor-to-scalar ratio value, rehabilitating several primordial potentials ruled out in the cold inflation context by the recent cosmic microwave background data Here we show that warm inflation is also able to produce a running of the running ${\ensuremath{\beta}}_{s}$ positive and within the Planck data limits This is very remarkable since the standard cold inflation model is unable to justify the current indication of a positive constraint on ${\ensuremath{\beta}}_{s}$ We achieve a parametrization for the primordial power spectrum able to take into account higher order effects as the running of the spectral index and the running of the running, and we perform statistical analysis using the most up-to-date Planck data to constrain the dissipative effects We find that the warm inflation can explain the current observables with a good statistical significance, even for those potentials ruled out in the simplest cold inflation scenario

TL;DR: In this article, a mass spectra for jets reconstructed using the anti-kt and Cambridge-Aachen algorithms is studied for different jet grooming techniques in data corresponding to an integrated luminosity of 5 inverse femtobarns, recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV.
Abstract: Invariant mass spectra for jets reconstructed using the anti-kt and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 inverse femtobarns, recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV. Leading-order QCD predictions for inclusive dijet and W/Z+jet production combined with parton-shower Monte Carlo models are found to agree overall with the data, and the agreement improves with the implementation of jet grooming methods used to distinguish merged jets of large transverse momentum from softer QCD gluon radiation.

TL;DR: In this article, an extended component-based analysis of the oily sludge from a flocculation-flotation unit of a wastewater treatment system in a refinery in Sweden was carried out over 1 year.
Abstract: Partly due to the complex and variable composition of oily sludge generated by the petroleum industry, cost-effective treatment and proper disposal pose considerable challenges worldwide. In this study, an extended component-based analysis of the oily sludge from a flocculation-flotation unit of a wastewater treatment system in a refinery in Sweden was carried out over 1 year. The heterogeneity of the oily sludge is illustrated by the wide ranges of concentrations found for different chemical components, particularly metals. Among the petroleum hydrocarbons, the most abundant compounds were nonpolar aliphatic hydrocarbons (63.7 ± 16.7 g kg−1); from the benzene, toluene, ethylbenzene, and xylene group, xylenes (91–240 mg kg−1) were most abundant; and among polycyclic aromatic hydrocarbons, naphthalene (25.7 ± 21.4), fluorene (27.25 ± 10.0), and phenanthrene (43.8 ± 18.4 mg kg−1) were most abundant (all results in terms of dry matter). Based on the EU guidelines and the mean concentration values for metals found in the oily sludge, e.g., Pb (135.4 ± 125.8), Cu (105.2 ± 79.1), Hg (42.8 ± 31.3), Ni (320 ± 267.4), and Zn (1321.7 ± 529.9 mg kg−1), disposal of oily sludge even in landfills for hazardous waste is not allowed. The organic content of the sludge can be reduced through biotreatment, but not the metal content. A multistep component-based treatment scheme is therefore needed.

TL;DR: Endothelial function is improved by tocilizumab in a high‐risk population, even as it increases total cholesterol and low‐density lipoprotein levels.
Abstract: Background Atherosclerosis is a chronic inflammatory disease, with interleukin 6 (IL‐6) as a major player in inflammation cascade. IL‐6 blockade may reduce cardiovascular risk, but current treatments to block IL‐6 also induce dyslipidemia, a finding with an uncertain prognosis. Methods and Results We aimed to determine the endothelial function responses to the IL‐6–blocking agent tocilizumab, anti–tumor necrosis factor α, and synthetic disease‐modifying antirheumatic drug therapies in patients with rheumatoid arthritis in a 16‐week prospective study. Sixty consecutive patients with rheumatoid arthritis were enrolled. Tocilizumab and anti–tumor necrosis factor α therapy were started in 18 patients each while 24 patients were treated with synthetic disease‐modifying antirheumatic drugs. Forty patients completed the 16‐week follow‐up period. The main outcome was flow‐mediated dilation percentage variation before and after therapy. In the tocilizumab group, flow‐mediated dilation percentage variation increased statistically significantly from a pre‐treatment mean of (3.43% [95% CI, 1.28–5.58] to 5.96% [95% CI, 3.95–7.97]; P =0.03). Corresponding changes were 4.78% (95% CI, 2.13–7.42) to 6.75% (95% CI, 4.10–9.39) ( P =0.09) and 2.87% (95% CI, −2.17 to 7.91) to 4.84% (95% CI, 2.61–7.07) ( P =0.21) in the anti–tumor necrosis factor α and the synthetic disease‐modifying antirheumatic drug groups, respectively (both not statistically significant). Total cholesterol increased significantly in the tocilizumab group from 197.5 (95% CI, 177.59–217.36) to 232.3 (201.62–263.09) ( P =0.003) and in the synthetic disease‐modifying antirheumatic drug group from 185.8 (95% CI, 169.76–201.81) to 202.8 (95% CI, 176.81–228.76) ( P =0.04), but not in the anti–tumor necrosis factor α group. High‐density lipoprotein did not change significantly in any group. Conclusions Endothelial function is improved by tocilizumab in a high‐risk population, even as it increases total cholesterol and low‐density lipoprotein levels.
