TL;DR: The low-frequency conductivity response of water-saturated packs of glass beads reflects a combination of two processes, which corresponds to the polarization of the mineral/water interface coating the surface of the grains and the Maxwell-Wagner polarization associated with accumulation of the electrical charges in the pore space of the composite medium.

TL;DR: In this paper, a measurement of the Z/gamma* boson transverse momentum spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of root s = 7TeV at the LHC is described.
Abstract: This paper describes a measurement of the Z/gamma* boson transverse momentum spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of root s = 7TeV at the LHC. The measurement is performed in the Z/gamma* -> e(+)e(-) and Z/gamma* -> mu(+)mu(-) channels, using data corresponding to an integrated luminosity of 4.7 fb(-1). Normalized differential cross sections as a function of the Z/gamma* boson transverse momentum are measured for transverse momenta up to 800 GeV. The measurement is performed inclusively for Z/gamma* rapidities up to 2.4, as well as in three rapidity bins. The channel results are combined, compared to perturbative and resummed QCD calculations and used to constrain the parton shower parameters of Monte Carlo generators.

TL;DR: This proposed anatomically based classification system provides a consistent description of the various osteotomies performed in spinal deformity correction surgery and will provide a common frame for osteotomy assessment and permit comparative analysis of different treatments.
Abstract: Background Global sagittal malalignment is significantly correlated with health-related quality-of-life scores in the setting of spinal deformity. In order to address rigid deformity patterns, the use of spinal osteotomies has seen a substantial increase. Unfortunately, variations of established techniques and hybrid combinations of osteotomies have made comparisons of outcomes difficult. Objective To propose a classification system of anatomically-based spinal osteotomies and provide a common language among spine specialists. Methods The proposed classification system is based on 6 anatomic grades of resection (1 through 6) corresponding to the extent of bone resection and increasing degree of destabilizing potential. In addition, a surgical approach modifier is added (posterior approach or combined anterior and posterior approaches). Reliability of the classification system was evaluated by an analysis of 16 clinical cases, rated 2 times by 8 different readers, and calculation of Fleiss kappa coefficients. Results Intraobserver reliability was classified as "almost perfect"; Fleiss kappa coefficient averaged 0.96 (range, 0.92-1.0) for resection type and 0.90 (0.71-1.0) for the approach modifier. Results from the interobserver reliability for the classification were 0.96 for resection type and 0.88 for the approach modifier. Conclusion This proposed anatomically based classification system provides a consistent description of the various osteotomies performed in spinal deformity correction surgery. The reliability study confirmed that the classification is simple and consistent. Further development of its use will provide a common frame for osteotomy assessment and permit comparative analysis of different treatments.

TL;DR: For severe acute respiratory syndrome (SARS)-CoV an RNA synthesis and proofreading pathway is demonstrated through association of nsp14 with the low-fidelity nsp12 viral RNA polymerase, which may explain its limited efficacy in vivo.
Abstract: Coronaviruses (CoVs) stand out among RNA viruses because of their unusually large genomes (∼30 kb) associated with low mutation rates. CoVs code for nsp14, a bifunctional enzyme carrying RNA cap guanine N7-methyltransferase (MTase) and 3′-5′ exoribonuclease (ExoN) activities. ExoN excises nucleotide mismatches at the RNA 3′-end in vitro, and its inactivation in vivo jeopardizes viral genetic stability. Here, we demonstrate for severe acute respiratory syndrome (SARS)-CoV an RNA synthesis and proofreading pathway through association of nsp14 with the low-fidelity nsp12 viral RNA polymerase. Through this pathway, the antiviral compound ribavirin 5′-monophosphate is significantly incorporated but also readily excised from RNA, which may explain its limited efficacy in vivo. The crystal structure at 3.38 A resolution of SARS-CoV nsp14 in complex with its cofactor nsp10 adds to the uniqueness of CoVs among RNA viruses: The MTase domain presents a new fold that differs sharply from the canonical Rossmann fold.

TL;DR: The primary endpoint was the annual asthma exacerbation rate at week 52 in the intention-to-treat population, and key secondary endpoints included prebronchodilator forced expiratory volume in 1 s (FEV1), Asthma Control Questionnaires-6 (ACQ-6), and Asthma Quality of Life Questionnaire-Standardised Version (AQLQ[S).
