Randomized trial of exercise in sedentary middle aged women: effects on quality of life
Increasing physical activity is currently considered to be a possible prevention strategy for cancer, obesity, and cardiovascular disease, either alone or in combination with dietary changes. This paper presents results of a randomized trial of moderate-to-vigorous intensity exercise in middle aged, sedentary women; specifically, we report changes in and correlates of quality of life and functional status of this exercise intervention program for both the short (three months) and longer term (12 months). The intervention group showed a significant increase in Mental Health score from baseline to 3 months (p < .01), significantly greater than the change in the control group at 3 months (p < .01). A similar trend among exercisers was observed for the General Health score (p < .01), and this finding was significantly greater than the change in control group at 3 months (p = .01). Change in Social Support â Affection were predictors of the changes in quality of life variables. This study documented improvements in quality of life and general functioning that occurred as a result of participating in an exercise intervention in sedentary middle-aged women

No reduction in C-reactive protein following a 12-month randomized controlled trial of exercise in men and women.
Low-grade systemic inflammation is suggested to play a role in the development of several chronic diseases including cancer. Higher levels of physical activity and lower adiposity have been associated with reduced levels of markers of systemic inflammation, such as C-reactive protein (CRP); however, reductions in CRP have not been observed consistently in randomized controlled trials of exercise. Purpose: To examine the effect of a 12-month aerobic exercise intervention on CRP levels in men and women. Methods: 102 men and 100 women, sedentary and aged 40-75 years, mean BMI of 29.9 and 28.7 kg/m2, respectively, were randomly assigned to a 12-month moderate-to-vigorous aerobic exercise intervention (6 d/wk, 60 min/d, 60-85% maximum heart rate) or control group. Fasting blood samples were collected at baseline and at 12-months. CRP levels were measured by high-sensitivity latex-enhanced nephelometry. Results: At baseline, CRP was 1.16 mg/L and 2.11 for men and women, respectively, and CRP was correlated with percent body fat (r=0.48, p â¤0.001), BMI (r=0.37, p â¤0.001) and aerobic fitness (r=-0.49, p â¤0.001). No intervention effects were observed for CRP in men or women, or when stratified by baseline BMI (< 30 kg/m2 vs. ⼠30 kg/m2) , baseline CRP (< 3 mg/L vs. ⼠3 mg/L) or change in body weight, body composition or aerobic fitness.
Conclusion: A 12 month moderate-to-vigorous aerobic exercise intervention did not affect CRP levels in previously sedentary men or women with average-risk CRP values at baseline
UBVRI Light Curves of 44 Type Ia Supernovae
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from
1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence
Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics. The
data set comprises 2190 observations and is the largest homogeneously observed
and reduced sample of SN Ia to date, nearly doubling the number of
well-observed, nearby SN Ia with published multicolor CCD light curves. The
large sample of U-band photometry is a unique addition, with important
connections to SN Ia observed at high redshift. The decline rate of SN Ia
U-band light curves correlates well with the decline rate in other bands, as
does the U-B color at maximum light. However, the U-band peak magnitudes show
an increased dispersion relative to other bands even after accounting for
extinction and decline rate, amounting to an additional ~40% intrinsic scatter
compared to B-band.Comment: 84 authors, 71 pages, 51 tables, 10 figures. Accepted for publication

Suppression of Ď(2S) production in p-Pb collisions at âsNN=5.02 TeV .
The ALICE Collaboration has studied the inclusive production of the charmonium state Ď(2S) in proton-lead (p-Pb) collisions at the nucleon-nucleon centre of mass energy âsNN = 5.02TeV at the CERN LHC. The measurement was performed at forward (2.03 < ycms < 3.53) and backward (â4.46 < ycms < â2.96) centre of mass rapidities, studying the decays into muon pairs. In this paper, we present the inclusive production cross sections Ď (2S), both integrated and as a function of the transverse momentum pT, for the two ycms domains. The results are compared to those obtained for the 1S vector state (J/Ď), by showing the ratios between the production cross sections, as well as the double ratios [Ď (2S)/ĎJ/ ]pPb/[Ď (2S)/ĎJ/ ]pp between p-Pb and proton-proton collisions. Finally, the nuclear modification factor for inclusive Ď(2S) is evaluated and compared to the measurement of the same quantity for J/Ď and to theoretical models including parton shadowing and coherent energy loss mechanisms. The results show a significantly larger suppression of the Ď(2S) compared to that measured for J/Ď and to models. These observations represent a clear indication for sizeable final state effects on Ď(2S) production
Energy dependence of the transverse momentum distributions of charged particles in pp collisions measured by ALICE
Differential cross sections of charged particles in inelastic pp collisions as a function of have been measured at = 0.9, 2.76 and 7 TeV at the LHC. The spectra are compared to NLO-pQCD calculations. Though the differential cross section for an individual cannot be described by NLO-pQCD, the relative increase of cross section with is in agreement with NLO-pQCD. Based on these measurements and observations, procedures are discussed to construct pp reference spectra at = 2.76 and 5.02 TeV up to = 50 GeV/c as required for the calculation of the nuclear modification factor in nucleus-nucleus and proton-nucleus collisions.publishedVersio

The new Inner Tracking System of the ALICE experiment
The ALICE experiment will undergo a major upgrade during the next LHC Long Shutdown scheduled in 2019–20 that will enable a detailed study of the properties of the QGP, exploiting the increased Pb-Pb luminosity expected during Run 3 and Run 4. The replacement of the existing Inner Tracking System with a completely new ultra-light, high-resolution detector is one of the cornerstones within this upgrade program. The main motivation of the ITS upgrade is to provide ALICE with an improved tracking capability and impact parameter resolution at very low transverse momentum, as well as to enable a substantial increase of the readout rate. The new ITS will consist of seven layers of innovative Monolithic Active Pixel Sensors with the innermost layer sitting at only 23 mm from the interaction point. This talk will focus on the design and the physics performance of the new ITS, as well as the technology choices adopted. The status of the project and the results from the prototypes characterization will also be presented.publishedVersio
Neutral meson production and correlation with charged hadrons in pp and Pb-Pb collisions with the ALICE experiment at the LHC
Among the probes used to investigate the properties of the Quark-Gluon Plasma, the measurement of the energy loss of high-energy partons can be used to put constraints on energy-loss models and to ultimately access medium characteristics, such as the energy density or the temperature. The study of two-particle correlations allows us to obtain very different constraints compared to the nuclear modification factor. In particular, the correlation of charged hadrons with high energy or direct photons is believed to give a measurement of the parton energy loss and insights into the medium-induced modification of the fragmentation process. High energy neutral pions are reconstructed using the ALICE electromagnetic calorimeters EMCal and PHOS, and the charged particles are detected by the main tracking detectors ITS and TPC. In these proceedings, the measurement of neutral mesons at \sqrt{s} = \(2.76 TeV in pp collisions are presented, as well as the measurements of azimuthal \(\pi^{0}.hadron correlations in pp and Pb-Pb collisions at TeV, and the extracted per-trigger yield modification factor . Comparisons with theoretical model calculations are also added.publishedVersio
