In this work, a novel low-alloyed Mg-Sn-Li-Al alloy with high-strength has been developed. The addition of ～1 wt% Li into the Mg-2Sn wt.% binary alloy can change the type of strengthening phases in Mg-2Sn-1Li sample(tl21),involving the formation of both Li2Mg Sn and Mg2Sn phases. The co-addition of ～1 wt% Al and ～1 wt% Li can further induce the higher density of both micron-sized phases and nano-precipitations in the Mg-2Sn-1Li-1Al sample(tlA211). The nano-precipitations can inhibit the grain growth, which thus lead to the fine grain size of ～1.38 μm in tlA211 sample, and ～1.59 μm in the tl21 sample. Besides, the profuse nano-phases would improve the yield strength via Orowan hardening effect. Consequently, the tl21 sample can exhibit the high yield strength of ～204 MPa, and elongation of ～6.6%. The tlA211 sample exhibits the much higher yield strength of～250 MPa, ultimate tensile strength of ～291 MPa, and also high elongation of ～9.0%. The high strength-ductility synergy, together with the low-Sn content, make the present Mg-Sn based alloy to be potential for the wider industrial applications.

目的分析骨质疏松性椎体压缩性骨折（OVCF）患者规范化抗骨质疏松治疗的现状及影响因素。方法回顾性选择2020年8月-2022年8月入住医院的196例OVCF患者为研究对象，依据出院后1年是否规范化服药分为未规范组（n=151）和规范组（n=45）。收集所有患者的一般社会学特征和疾病相关特征，通过单因素分析及多因素Logistic回归分析影响规范化抗骨质疏松治疗现状的因素。结果患者出院1个月时规范化服药占82.65%，随后逐渐降低，至出院1年时降至22.96%，呈现明显的线性趋势（P<0.05）。单因素分析发现，两组患者之间的吸烟饮酒、受教育程度及医保类型差异有统计学意义（P<0.05）。经多因素Logistic回归方程分析，发现吸烟饮酒、受教育程度、医保类型是影响规范化服药的因素（P<0.05）。结论 OVCF患者出院后抗骨质疏松药物规范化服药的比例呈逐渐降低趋势，吸烟饮酒、受教育程度、医保类型是影响出院后患者规范化治疗的因素。

3-D Networks-on-Chip （NoC） emerge as a potent solution to address both the interconnection and design complexity problems facing future Multiprocessor System-on-Chips （MPSoCs）. Effective run-time mapping on such 3-D NoC-based MPSoCs can be quite challenging, as the arrival order and task graphs of the target applications are typically not known a priori, which can be further complicated by stringent energy requirements for NoC systems. This paper thus presents an energy-aware run-time incremental mapping algorithm （ERIM） for 3-D NoC which can minimize the energy consumption due to the data communications among processor cores, while reducing the fragmentation effect on the incoming applications to be mapped, and simultaneously satisfying the thermal constraints imposed on each incoming application. Specifically, incoming applications are mapped to cuboid tile regions for lower energy consumption of communication and the minimal routing. Fragment tiles due to system fragmentation can be gleaned for better resource utilization. Extensive experiments have been conducted to evaluate the performance of the proposed algorithm ERIM, and the results are compared against the optimal mapping algorithm （branch-and-bound） and two heuristic algorithms （TB and tl）. The experiments show that ERIM outperforms TB and tl methods with significant energy saving （more than 10%）, much reduced average response time, and improved system utilization.
