Performing artist and Athlete Health Monitor: User experience, content and conditions for use of an online dance-health surveillance system in a professional ballet company
Objectives The user experience, content and conditions for use of an online dance-health surveillance system (Performing artist and Athlete Health Monitor, PAHM) was examined through a focus group interview with professional ballet dancers. Methods Nine professional dancers (56% female (n=5), average age=27.56± 5.17) completed biweekly questionnaires using the PAHM, including questions on health problems, injuries, mental complaints and illnesses. After 6 weeks, nine dancers participated in a focus group interview to investigate the user experience, content and conditions for use of the PAHM. Data were analysed using thematic analysis. Results 25 of the 27 questionnaires were completed (response rate of 93%). Dancers were positive about using the PAHM. They recommend to clarifying the questions about pain and injury, expanding items on mental health, including items on workload, sleep, rest and nutrition, and receiving feedback regarding their own results. Dancers were reluctant regarding sharing their personal data with others. Data on an aggregated l
Production of singlet P-wave and states
No spin-singlet quarkonium state has yet been observed. In this
paper we discuss the production of the singlet P-wave and
states and . We consider two possibilities. In the first the
states are produced via the electromagnetic cascades \ups(3S) \to
\eta_b(2S) + \gamma \to h_b + \gamma \gamma \to \eta_b +\gamma\gamma\gamma
and . A more promising process consists of single pion
transition to the state followed by the radiative transition to the
state: \ups(3S)\to h_b + \pi^0 \to \eta_b + \pi^0 +\gamma and . For a million \ups(3S) or
's produced we expect these processes to produce several hundred events.Comment: 13 pages, LaTeX, 1 figure, to be published Phys. Rev. D. Some

Geographic and temporal variation in the consumption of bats by European barn owls
Capsule We report a review of the occurrence of bats in the Barn Owl diet Tyto alba in Europe. Based on 802 studies reporting 4.02 million prey items identified in pellets, 4949 were bats (0.12%). We found that bat predation decreased during the last 150 years, is more frequent on islands than mainland, and is higher in eastern than western Europe and in southern than northern Europe. Although Barn Owls usually capture bats opportunistically, they can sometimes specialize on them
