硼硅酸盐生物活性玻璃基(Borosilicate bioactive glass-based,BBG)骨水泥由于其优异的生物活性和生物降解性,在治疗骨质疏松性骨折以及骨肿瘤、骨创伤、骨髓炎等疾病方面具有重要的应用前景,受到人们的广泛关注。为进一步了解氨基酸对其植入生物体内后的矿化影响,本研究在常规的SBF溶液中添加了不同种类及浓度的氨基酸物质,重点研究对植入体表面形貌的影响。同时为在矿化过程中同步形成白磷钙矿(Whitlockite,WH)和羟基磷灰石(hydroxyapatite,HA),调整了SBF溶液的温度以及酸碱度和Mg^(2+)浓度,研究了不同SBF溶液中BBG骨水泥表面形成的矿化产物。研究结果表明,不同的氨基酸及浓度的变化对矿化产物的影响有较大差异,天冬氨酸和赖氨酸的浓度变化影响矿物的长径比,而甘氨酸对矿物形貌的影响较小。将硼硅酸盐生物活性玻璃压片放置在70℃下的高Mg^(2+)浓度的酸性(pH=3.5)SBF溶液中浸泡一定时间后,能够获得HA/WH的复相矿物。

以溶胶-凝胶法制备的介孔硼硅酸盐生物活性玻璃微球(MBGS)作为固相,海藻酸钠(SA)溶液作为液相,开发了一种可注射复合骨水泥。对MBGS中氧化硼/氧化硅的比例对其质构性能及骨水泥的可操作性、抗压强度和生物活性的影响进行表征。实验结果表明,随着硼含量的增加,MBGS的比表面积从161.71 m^2/g增大至214.28 m^2/g,平均孔径以及总孔容也随之增长,加速了玻璃相中钙离子的释放,使得玻璃与SA的快速交联,改善了骨水泥可操作性能和力学性能,凝固时间由21 min缩短至9 min,抗压强度由3.4 MPa提升至4.1 MPa,体外矿化性能也随之提高。综合各方面性能表现,BC-30骨水泥兼具良好的可操作性能、力学性能和体外矿化能力,是最合适的骨水泥组分。总之,提高MBGS的质构性能是增强复合骨水泥的可操作性、抗压强度和生物活性的有效方法。

New findings on the influence of El Nino events on tropical cyclone formation

引用

Science China Earth Sciences 2024年第3期67卷 892-893页

作者： Liguang wu Department of Atmospheric and Oceanic Sciences Institute of Atmospheric SciencesFudan UniversityShanghai 200438China

Tropical cyclones typically form over warm tropical and subtropical ocean surfaces, as their formation and intensification rely primarily on the energy provided by the ocean. Pioneering research by Gray (1968) revealed that the formation of tropical cyclones requires the sea surface temperature (SST) to be no less than 26.5℃. Consequently, SST is commonly recognized as a crucial parameter among the environmental factors influencing tropical cyclone formation(Gray, 1979;Emanuel and Nolan, 2004).

On equivalence of state-based potential games

Science China(Information Sciences) 2024年第6期67卷 313-327页

作者： Han wu Jinhuan WANG Institute of Mathematics School of ScienceHebei University of Technology

In this paper, we explore state-based potential games using the semi-tensor product of ***, applying the potential equation, we derive both a necessary and sufficient condition as well as a sufficient condition to verify whether a state-based game qualifies as a potential game. Next, we present two static equivalence conditions of state-based potential games. We then delve into dynamic equivalence. We propose a criterion that allows us to identify state-based games that are dynamically equivalent to state-based potential games and share similar dynamic properties. Ultimately, we introduce the concept of state-based networked evolutionary games. We provide a necessary and sufficient condition to ensure that a state-based networked evolutionary game can be classified as a state-based potential game.
