Energy Level Statistics in Particle—Rotor Model

Energy level statistics of a system consisting of six particles interacting by delta force in a two- model coupled with a deformed core is studied in particle-rotor model. For single- shell and two- shell the exact energies for our statistical analysis are obtained from a full diagonalization of the Hamiltonian, while in two- case the configuration truncation is used. The nearest-neighbor distribution of energy levels and spectral rigidity are studied as the function of spin. The results of single- shell are compared with those in two- case. It is showed that the system becomes more regular when single- space is replaced by two- shell although the basis size of the configuration space is unchanged. The degree of chaoticity of the system, however, changes slightly when configuration space is enlarged by extending single- shell to two- shell .

Nuclear Chaotic Behavior in a Two—j Shell Coupled with a Rotor Model

The chaotic properties for six particles interacting by a monopole pairing force in a two-j shell model coupled with a deformed core are studied in the frame of particle-rotor model. The nearest-neighbor distribution of energy levels and spectral rigidity in the two-j shell are compared with those in the single-j case. The results show that the system is more regular in the two-j model than that in the single-j case.

2015年-2020年某三级综合医院噬血细胞综合征患者构成及住院费用分析

目的分析某院噬血细胞综合征患者构成及住院费用变化情况,探讨进一步降低患病率和合理控制费用提提供参考依据。方法收集整理北京市某三甲综合医院2015年1月1日-2020年12月31日收治的主要诊断为噬血细胞综合征患者,对其性别、患者来源地区、年龄、住院天数、治疗类型、离院方式、住院费用等进行回顾性分析,通过Wilcoxon秩和检验、Kruskal-WallisH检验和Cox-Stuart趋势存在性检验比较分析不同特征患者住院人次及费用情况。结果6年间不同特征噬血细胞综合征患者呈持续增长模式,外地患者占92.54%,平均住院费用35975元;18岁~40岁患者占53.15%,平均住院费用40279元;1天~7天患者占51.94%,平均住院费用13237元;非初治患者占65.95%,初治患者平均住院费用43812元;医嘱离院患者占88.96%,死亡患者平均住院费用98486元。噬血细胞综合征患者平均住院费用呈波动性增长趋势,在2016年为45970元最高,2020年药品费用构成比和材料费用构成比最低占12.9%和4.6%。结论对于噬血细胞综合征患者,应加强地方医疗建设,加大青少年和中年患者的健康教育,提高病床周转率和医疗服务效率来降低患者住院费用减少患者家庭经济负担,争取实现早诊断早治疗,提高噬血细胞综合征患者生存率。
