TL;DR: The European Union's Emissions Trading Scheme (EU ETS) is the world's largest market for carbon and the most significant multinational initiative ever taken to mobilize markets to protect the environment as discussed by the authors.
Abstract: The European Union's Emissions Trading Scheme (EU ETS) is the world's largest market for carbon and the most significant multinational initiative ever taken to mobilize markets to protect the environment. It will be an important influence on the development and implementation of trading schemes in the US, Japan, and elsewhere. However, as is true of any pioneering public policy experiment, this scheme has generated much controversy. Pricing Carbon provides the first detailed description and analysis of the EU ETS, focusing on the first 'trial' period of the scheme (2005–7). Written by an international team of experts, it allows readers to get behind the headlines and come to a better understanding of what was done and what happened based on a dispassionate, empirically based review of the evidence. This book should be read by anyone who wants to know what happens when emissions are capped, traded, and priced.

TL;DR: It is suggested that the AITL spectrum may be wider than suspected, as a subset of CD30(-) PTCLs-u may derive from or be related to AIT l, and T(FH) cells represent the normal counterpart of AITl.

TL;DR: In this paper, the existence and uniqueness of a global strong solution for isentropic compressible fluids with initial data close to a stable equilibrium was proved by uniform estimates for a mixed hyperbolic/parabolic linear system with convection term.
Abstract: We investigate global strong solutions for isentropic compressible fluids with initial data close to a stable equilibrium. We obtain the existence and uniqueness of a solution in a functional setting invariant by the scaling of the associated equations. More precisely, the initial velocity has the same critical regularity index as for the incompressible homogeneous Navier-Stokes equations, and one more derivative is needed for the density. We point out a smoothing effect on the velocity and a L 1-decay on the difference between the density and the constant reference state. The proof lies on uniform estimates for a mixed hyperbolic/parabolic linear system with a convection term.

TL;DR: In this paper, a very high-energy γ-ray emission from the Galactic Centre region has been measured using HESS, the High Energy Stereoscopic System recently constructed in Namibia, South West Africa.
Abstract: Events at the centre of our Galaxy are key to our understanding of high-energy processes in the Universe, since it contains examples of virtually every type of exotic object known to astronomers. The very-high-energy γ-ray emission from the Galactic Centre region has now been measured using HESS, the High Energy Stereoscopic System recently constructed in Namibia, South West Africa. HESS operates at energies above the regime accessible to satellite-based detectors, taking γ-ray astronomy into new territory. The results show that these clouds are glowing in very high energy γ-rays. The glow is caused by constant bombardment of the clouds by cosmic rays — probably protons and nuclei — produced close to the central black hole or in the expanding blast waves of supernova explosions. The source of Galactic cosmic rays (with energies up to 1015 eV) remains unclear, although it is widely believed that they originate in the shock waves of expanding supernova remnants1,2. At present the best way to investigate their acceleration and propagation is by observing the γ-rays produced when cosmic rays interact with interstellar gas3. Here we report observations of an extended region of very-high-energy (> 1011 eV) γ-ray emission correlated spatially with a complex of giant molecular clouds in the central 200 parsecs of the Milky Way. The hardness of the γ-ray spectrum and the conditions in those molecular clouds indicate that the cosmic rays giving rise to the γ-rays are likely to be protons and nuclei rather than electrons. The energy associated with the cosmic rays could have come from a single supernova explosion around 104 years ago.

TL;DR: Liver stiffness measurement using transient elastography using fibroScan®, Echosens™ has been shown to be correlated to liver fibrosis in various chronic liver diseases and this study aims to assess its diagnosis accuracy in patients with chronic hepatitis B.
Abstract: Background: The need for new non-invasive tools to assess liver fibrosis in chronic liver diseases has been largely advocated. Liver stiffness measurement (LSM) using transient elastography (FibroScan®, Echosens™) has been shown to be correlated to liver fibrosis in various chronic liver diseases. This study aims to assess its diagnosis accuracy in patients with chronic hepatitis B. Patients and methods: We prospectively enrolled 202 patients with chronic hepatitis B in a multicentre study. Patients underwent liver biopsy (LB) and LSM. METAVIR and Ishak liver fibrosis stages were assessed by two pathologists. Results: LSM or LB was considered unreliable in 29 patients. Statistical analysis was conducted in 173 patients. LSM was significantly (P<0.001) correlated with METAVIR (r=0.65) and Ishak fibrosis stage (0.65). The area under receiver-operating characteristic curves were 0.81 (95% confidence intervals, 0.73–0.86) for F≥2, 0.93 (0.88–0.96) for F≥3 and 0.93 (0.82–0.98) for F=4. Optimal LSM cut-off values were 7.2 and 11.0 kPa for F≥2 and F=4, respectively, by maximizing the sum D of sensitivity and specificity, and 7.2 and 18.2 kPa by maximizing the diagnosis accuracy. Conclusion: In conclusion, LSM appears to be reliable for detection of significant fibrosis or cirrhosis in HBV patients and cut-off values are only slightly different from those observed in HCV patients.
