Shell-model Study of Neutron-rich Λ-hypernucleus _Λ^(10)Li

原子核物理评论 2009年第S1期26卷 59-63页

作者： a.umeya T.Harada Research Center for Physics and Mathematics Osaka Electro-Communication University

We investigate a Σ-mixing probability of a neutron-rich Λ-hypernucleus 10ΛLi by using microscopic shell-model calculations considering a Λ-Σ coupling in the first order perturbation. The theoretical Σ-mixing probability in 10ΛLi is found to be about 0.48%,due to the appearance of multi-configuration Σ Nuclear excited states which can be strongly coupled with the Λ ground state in 10ΛLi.

AIM:To identify factors contributing to visual improvement after treatment of macular edema(ME)secondary to branch retinal vein occlusion(BRVO),and to assess the interaction between laser therapy and intravitreal ranibizumab(IVR).METHODS:We retrospectively reviewed the medical records of patients who had been treated for BRVO-related ME at our *** were traceable for at least 12 mo,and evaluated factors included age,sex,medical history,smoking history,treatment methods,foveal hemorrhage,and change in visual *** included laser therapy,IVR,sub-Tenon’s capsule injection of triamcinolone(STTA),a combination,or no *** logistic regression analysis and interaction terms were used to assess the clinical efficacy of the treatments,and odds ratios(OR)and 95%confidence intervals(CI)were ***:Seventy-three patients(34 men,39 women;73 eyes)with a mean age of 69.4±12.1 y were *** who underwent IVR monotherapy,laser monotherapy,and STTA+laser had significantly higher best corrected visual acuity at 12 mo compared to baseline(P<0.001,<0.001,and 0.019,respectively).Logistic regression analysis without interaction terms found that IVR was a significant visual acuity recovery factor(adjusted OR:3.89,95%CI:1.25-12.1,P=0.019).Adjusted OR using an interaction model by logistic regression was 16.6(95%CI:2.54-108.47,P=0.003)with IVR treatment,and 8.25(95%CI:1.34-50.57,P=0.023)with laser *** interaction was observed(adjusted OR:0.07,95%CI:0.01-0.75,P=0.029).CONCLUSION:IVR contributes to improvements in visual acuity at 12 mo in ME secondary to *** interaction is observed between laser therapy and IVR treatments.
