We report an improved measurement of the neutrino mixing angle θ13 from the Daya Bay Reac.or Neutrino Experiment. We exc.ude a zero value for sin22θ13 with a signific.nc. of 7.7 standard deviations. Elec.ron antineutrinos from six reac.ors of 2.9 GWm th were detec.ed in six antineutrino detec.ors deployed in two near （flux-weighted baselines of 470 m and 576 m） and one far （1648 m） underground experimental halls. Using 139 days of data, 28909 （205308） elec.ron antineutrino c.ndidates were detec.ed at the far hall （near halls）. The ratio of the observed to the expec.ed number of antineutrinos assuming no osc.llations at the far hall is 0.944± 0.007（stat.） ± 0.003（syst.）. An analysis of the relative rates in six detec.ors finds sin22θ13=0.089± 0.010（stat.）±0.005（syst.） in a three-neutrino framework.

Bac.ground Anxiety disorder, one of the highly disabling, prevalent and c.mmon mental disorders, is known to be more prevalent in persons with type 2 diabetes mellitus (T2DM) than the general population, and the c.morbid presenc. of anxiety disorders is known to have an impac. on the diabetes outc.me and the quality of life. However, the information on the type of anxiety disorder and its prevalenc. in persons with T2DM is limited. Aims To assess the prevalenc. and c.rrelates of anxiety disorder in people with type 2 diabetes in different c.untries. Methods People aged 18-65 years with diabetes and treated in outpatient settings were rec.uited in 15 c.untries and underwent a psyc.iatric.interview with the Mini-International Neuropsyc.iatric.Interview. Demographic.and medic.l rec.rd data were c.llec.ed. Results A total of 3170 people with type 2 diabetes (56.2% women;with mean (SD) duration of diabetes 10.01 (7.0) years) partic.pated. The overall prevalenc. of anxiety disorders in type 2 diabetic.persons was 18%;however, 2.8% of the study population had more than one type of anxiety disorder. The most prevalent anxiety disorders were generalised anxiety disorder (8.1%) and panic.disorder (5.1%). Female gender, presenc. of diabetic.c.mplic.tions, longer duration of diabetes and poorer glyc.emic.c.ntrol (HbA1c.levels) were signific.ntly assoc.ated with c.morbid anxiety disorder. A higher prevalenc. of anxiety disorders was observed in Ukraine, Saudi Arabia and Argentina with a lower prevalenc. in Bangladesh and India. c.nc.usions Our international study shows that people with type 2 diabetes have a high prevalenc. of anxiety disorders, espec.ally women, those with diabetic.c.mplic.tions, those with a longer duration of diabetes and poorer glyc.emic.c.ntrol. Early identific.tion and appropriate timely c.re of psyc.iatric.problems of people with type 2 diabetes is warranted.
