All-sky search for gravitational-wave bursts in the second joint LIGO-Virgo run

We present results from a search for gravitational-wave bursts in the data collected by the LIGO and Virgo detectors between July 7, 2009 and October 20, 2010: data are analyzed when at least two of the three LIGO-Virgo detectors are in coincident operation, with a total observation time of 207 days. The analysis searches for transients of duration < 1 s over the frequency band 64-5000 Hz, without other assumptions on the signal waveform, polarization, direction or occurrence time. All identified events are consistent with the expected accidental background. We set frequentist upper limits on the rate of gravitational-wave bursts by combining this search with the previous LIGO-Virgo search on the data collected between November 2005 and October 2007. The upper limit on the rate of strong gravitational-wave bursts at the Earth is 1.3 events per year at 90% confidence. We also present upper limits on source rate density per year and Mpc^3 for sample populations of standard-candle sources. As in the previous joint run, typical sensitivities of the search in terms of the root-sum-squared strain amplitude for these waveforms lie in the range 5 10^-22 Hz^-1/2 to 1 10^-20 Hz^-1/2. The combination of the two joint runs entails the most sensitive all-sky search for generic gravitational-wave bursts and synthesizes the results achieved by the initial generation of interferometric detectors.Comment: 15 pages, 7 figures: data for plots and archived public version at https://dcc.ligo.org/cgi-bin/DocDB/ShowDocument?docid=70814&version=19, see also the public announcement at http://www.ligo.org/science/Publication-S6BurstAllSky

Effect of 12-Week Pilates Trainning on EDSS in Women Suffering fromMultiple Sclerosis

Abstract Background & aim: Multiple sclerosis is a debilitating disease that strikes the immune system. Multiple sclerosis is a chronic disease which debilitates the nervous system. The study was evaluated the effects of Pilates exercise on women with physical disabilities suffering from multiple sclerosis for 12 weeks .The aim of this study was to investigating the effects of Pilates trainning on EDSS of women suffering from Multiple Sclerosis (MS) for 12 weeks. Methods: In the present clinical trial study, 38 patients age 20-40 years (mean disease duration of 8±2 years) with multiple sclerosis grade 0-4.5 were selected. The Patients were randomly divided into two groups: experimental and control groups. The training program for pilates, 12 weeks, three sessions a week, with each session consisting of 60 minutes. Patients' physical disability was measured using Krutzke Expanded Disability Status Scale, before and after exercise. Data were analyzed by ANCOVA test. Results: Physical disability scores before and after the exercise in intervention was 47.1 and 37 and in the control group, was 93.1 and 43.1 respectively, which was significantly different in the intervention group before and after training (p<0.05). Conclusion: Pilates training improves the physical disability of MS patients. Therefore, this exercise can be used as a complementary treatment alongside drug treatments.
