Higher harmonic anisotropic flow measurements of charged particles in Pb-Pb collisions at 2.76 TeV
We report on the first measurement of the triangular , quadrangular
, and pentagonal charged particle flow in Pb-Pb collisions at 2.76
TeV measured with the ALICE detector at the CERN Large Hadron Collider. We show
that the triangular flow can be described in terms of the initial spatial
anisotropy and its fluctuations, which provides strong constraints on its
origin. In the most central events, where the elliptic flow and
have similar magnitude, a double peaked structure in the two-particle azimuthal
correlations is observed, which is often interpreted as a Mach cone response to
fast partons. We show that this structure can be naturally explained from the
measured anisotropic flow Fourier coefficients.Comment: 10 pages, 4 figures, published version, figures at

The burden of vulvovaginal atrophy on women's daily living: Implications on quality of life from a face-to-face real-life survey
Objective:This subanalysis of the European Vulvovaginal Epidemiology Survey study aimed to assess the correlation of vulvovaginal atrophy (VVA) symptoms and severity, when confirmed by objective gynecologic examination, with the quality of life of postmenopausal women.Methods:Women aged 45 to 75 years with confirmation of last menstrual period more than 12 months before, who attended menopause or gynecology centers, were included. Those women had at least one VVA symptom filled in a group of questionnaires, including EuroQol-EQ-5D-3L and Day-to-Day Impact of Vaginal Aging (DIVA). To confirm the VVA diagnosis, an objective gynecologic examination was also performed.Results:Of a total of 2,160 evaluable women, 66.3%, 30.5%, and 11.2% suffered from severe vaginal, vulvar, and urinary symptoms, respectively. VVA was confirmed in more than 90% of the participants. Mean (\ub1SD) EQ-5D-3L score was 0.892\u200a\ub1\u200a0.144 and mean (\ub1SD) score on the associated visual analog scale was 71.7\u200a\ub1\u200a16.0. Mean (\ub1SD) DIVA score was 0.922\u200a\ub1\u200a0.653. For both EQ-5D-3L and DIVA, the overall scores and most of the dimensions/components were statistically significantly worse for women with severe VVA symptoms (vulvar and urinary) compared with women not affected by severe symptoms. Quality of life questionnaires showed worse scores in women where the diagnosis of VVA was confirmed by gynecologic examination.Conclusions:Severe VVA symptoms showed a direct association with worse quality of life in postmenopausal women. This important effect on the quality of life of many women should be recognized as equivalent to those from other conditions and pathologies of which there is greater awareness
Charged kaon femtoscopic correlations in pp collisions at sqrts=7 TeV.
Correlations of two charged identical kaons (KchKch) are measured in pp collisions at
1as = 7 TeV by the ALICE experiment at the Large Hadron Collider (LHC). One-dimensional KchKch correlation
functions are constructed in three multiplicity and four transverse momentum ranges. The KchKch femtoscopic source parameters R and are extracted. The KchKch correlations show a slight increase of femtoscopic radii with increasing multiplicity and a slight decrease of radii with increasing transverse momentum. These trends are similar to the ones observed for and K0s K0s correlations in pp and heavy ion collisions. However at high multiplicities, there is an indication that the one-dimensional correlation radii for charged kaons are larger than those for pions in contrast to what was observed in heavy-ion collisions at the Relativistic Heavy-Ion Collider
