Neoclassical tearing modes on AUG: improved scaling laws, high confinement at high β_N and new stabilization experiments

The accuracy of the scaling laws derived so far for the normalised beta values at the onset of neoclassical tearing modes is limited as the results depend on the presence and magnitude of seed islands. Therefore power ramp down experiments have been performed on ASDEX Upgrade, allowing to find a scaling law for the critical β value at which the NTMs disappear. For (m,n)=(3,2) NTMs these critical beta values have been found to scale nearly proportional to ρ*. As it has been recently found on ASDEX Upgrade, at high βN values there is a regime in which (3,2) NTMs cause a much smaller confinement degradation as one would expect from the β dependence of the saturated island size. The transition to this regime allows high confinement (H = 1) at high beta values ( βN > 2.3) on ASDEX Upgrade in spite of the presence of (3,2) NTMs. The plasma conditions for the transition into such a high confinement regime are discussed in detail. Furthermore, new results on NTM stabilization by localized ECCD will be presented, showing that NTMs remain stabilized even with increased heating power and thus normalized beta values well above the NTM threshold

Assessing the relationship between markers of glycemic control through flexible copula regression models

Glycated haemoglobin (HbA1c) is a sensitive marker of blood glucose in patients with diabetes. However, levels can vary considerably, even amongst individuals with similar mean blood glucose concentrations. Other glycated proteins, such as fructosamine, can also act as blood sugar markers, but estimating HbA1c and fructosamine via independent models may lead to errors of interpretation regarding disease severity. From a clinical standpoint, it would be of great interest to know the factors that affect the mean concentration of both HbA1c and fructosamine, which influence the variability in the concentrations of these glycated markers and cause HbA1c/fructosamine discordance. Flexible models are required to illustrate the behaviour of these variables as well as the association between them. This work reviews existing models that might serve in this regard. Flexible copula regression models using splines were used to provide a better understanding of the behaviour of both glycated proteins and the relationship between them under the possible influence of different covariates. This work shows the usefulness of this type of models in practise and provides a basis for their clinical interpretation by means of an understandable case study. Ultimately, to better understand the effects of each continuous covariate, they are represented at the true scale of the response variables

Dienogest 2 mg Daily in the Treatment of Adolescents with Clinically Suspected Endometriosis: The VISanne Study to Assess Safety in ADOlescents

Study Objective: To study the safety and efficacy of dienogest 2 mg in adolescents with suspected endometriosis.Design: A 52-week, open-label, single-arm study.Setting: In 21 study centers, in 6 European countries.Participants: Adolescents aged 12 to younger than 18 years with clinically suspected or laparoscopically confirmed endometriosis.Interventions: Dienogest 2 mg once daily.Main Outcome Measures: The primary end point was relative change in lumbar spine (L2-L4) bone mineral density (BMD) measured using dual-energy x-ray absorptiometry. A key secondary end point was change in endometriosis-associated pain assessed using a visual analogue scale.Results: Of 120 patients screened, 111 comprised the full-analysis set (ie, patients who took >= 1 dose of study drug and had >= 1 post-treatment observation) and 97 (87.4%) completed the study. Mean lumbar BMD at baseline was 1.1046 (SD, 0.1550) g/cm(2). At the end of dienogest treatment (EOT; defined as at 52 weeks or premature study discontinuation), mean relative change in BMD from baseline was -1.2% (SD, 2.3%; n 5 103). Follow-up measurement 6 months after EOT in the subgroup with decreased BMD at EOT (n 5 60) showed partial recovery in lumbar BMD (mean change from baseline: -2.3% at EOT, -0.6% 6 months after EOT). Mean endometriosis-associated pain score was 64.3 (SD, 19.1) mm at baseline and decreased to 9.0 (SD, 13.9) mm by week 48.Conclusion: In adolescents with suspected endometriosis, dienogest 2 mg for 52 weeks was associated with a decrease in lumbar BMD, followed by partial recovery after treatment discontinuation. Endometriosis-associated pain was substantially reduced during treatment. Because bone accretion is critical during adolescence, results of the VISanne study to assess safety in ADOlescents (VISADO) study highlights the need for tailored treatment in this population, taking into account the expected efficacy on endometriosis-associated pain and an individual's risk factors for osteoporosis

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO
