Canonical interpretation of and in the family
Inspired by the new resonance , we calculate the masses and
two-body OZI-allowed strong decays of the higher vector bottomonium sates
within both screened and linear potential models. We discuss the possibilities
of and as mixed states via the mixing. Our
results suggest that and might be explained as
mixed states between - and -wave vector states. The
and resonances may correspond to the mixed states
dominated by the - and -wave components, respectively. The mass and the
strong decay behaviors of the resonance are consistent with
the assignment of the state in the potential models.Comment: 9 pages, 4 figures. More discussions are adde
Effects of combined therapy in 80 cases of accommodative esotropia
AIM: To investigate a comprehensive treatment for accommodative esotropia.<p>METHODS: Eighty patients with accommodative esotropia were analyzed. All cases wore corrective glasses 7d after mydriasis by 10g/L atropine. The pupils were all comprehensively trained. If the position of the esotropic eyes could not be corrected by spectacles and both eyes had similar visual acuity in one year, surgical intervention was taken to correct the position. Refraction, visual acuity, visual function and strabismus degree change before and after treatment were evaluated.<p>RESULTS: One year after wearing glasses, 50 cases had corrected eye position through correction and 30 cases were partially accommodative esotropia. Ten cases of esotropia degree >+15<sup>â–³</sup> which could not be complete corrected by cure correction got surgical intervention. Seven cases of them got normal eye positions and 3 cases were over corrected 10<sup>â–³</sup>-20<sup>â–³</sup>. After comprehensive treatment of 3 years, the cure rate of amblyopia was 88.7%.<p>CONCLUSION: The treatment for accommodative esotropia is a comprehensive course. It is necessary to pay attention to eye position correction, but also for the treatment of amblyopia, while paying attention to establish binocular vision
