Dear Editor,Severe fever with thrombocytopenia syndrome(SFTS)is an emerging tick-borne infectious disease caused by a novel bunyavirus called SFTS virus(SFTSV).It was initially identified in China in 2009(Yu et al.,2011).Since then,the number of reported SFTS cases has rapidly increased in China,South Korea,and Japan(Li,et al.,2018;Takahashi et al.,2014;Kim et al.,2018).Sporadic SFTS cases have also been identified in several other Asian countries,such as Vietnam,Pakistan,Myanmar,and Thailand(Takahashi et al.,2014;Tran et al.,2019;Li et al.,2021).This disease is recognized as a highly lethal viral hemorrhagic fever with a mortality rate ranging from 12%to 50%(Yu et al.,2011;Li et al.,2018;Takahashi et al.,2014;Kim et al.,2013).SFTS primarily spreads to humans through bites from ticks infected with SFTSV,with the Haemaphysalis longicornis tick acting as the predominant vector for SFTSV(Zhuang et al.,2018).

为保证加氢站氢气供应、降低氢气终端价格,对不同加氢站供氢路径的经济可行性与适用场景进行了探讨。研究基于氢气的平准化成本建立了典型外供氢加氢站与站内制氢加氢站的经济模型,并对制氢原材料成本、氢气运输距离、能耗等关键影响因素进行敏感度分析,探究了不同来源和供给模式下氢气终端成本的形成机制。此外,通过建立生命周期模型,分析未来可能的碳税对于氢气消费终端价格的影响。结果表明,运输距离与单车承载量是外供氢路径下影响终端成本的主要因素,在考虑碳税情况下这种影响更为显著,而站内制氢路径下影响成本的主要因素为原材料价格和制氢能耗。有机液体储氢运输经济运输距离为220~1700 km,可覆盖我国主要大规模氢气运输场景;天然气站内重整在天然气供应充足、价格低于4元/m^(3)时优势明显;站内电解水与可再生能源发电结合经济和环境优势明显,供氢价格可维持在35元/kg以下。研究指明了我国加氢站不同供氢方式的未来发展方向,为供氢路径选择提供了可靠的经济评价方法,有望对加氢站建设与地区氢能发展政策制定提供有益参考。

培育具备强大韧性的集群生态圈是推动集成电路产业集群高质量发展的关键问题。将产业集群视为一个动态系统,从理论上探讨集群韧性的演化逻辑和提升路径。在适应性循环理论视角下,韧性系统具备随情境而动态平衡的稳定性与复杂性,以及内部主体的弱网络关联性。突发事件冲击下,产业集群在“冲击吸收-冲击适应-恢复更新-再组织”四阶段具有复杂韧性演化逻辑。当前,集成电路产业集群面临人才紧缺、技术封锁、超长链条、产业体系依赖等困境,应遵循阶段演化的复杂逻辑,以培育自主可控的产业韧性系统为目标导向,塑造“抵抗-适应-恢复-再组织”的韧性能力,以实现集群韧性水平的螺旋式上升。

bi_(2)SeO_(5)是一种具有优异电绝缘性能的范德华(vdW)层状介电材料,引起了极大关注.然而,目前关于bi_(2)SeO_(5)的研究主要停留在实验层面,仍然缺乏对其原子级薄膜的介电性能的相关理论认识.本文通过第一性原理计算确定了bi_(2)SeO_(5)的介电性能,发现其块体、双层和单层均具有超高平均介电常数(εr>20).研究表明,单层bi_(2)SeO_(5)与双层bi_(2)O_(2)Se之间的导带和价带能量偏移量均大于1 eV,表明单层bi_(2)SeO_(5)依然可作为原子薄bi_(2)O_(2)Se的良好介电层.此外,不同于h-BN或其他2D vdW绝缘体,bi_(2)SeO_(5)的εr由其离子部分主导,且随着厚度的减小几乎保持不变.计算发现,单层bi_(2)SeO_(5)的等效氧化层厚度可薄至0.3 n m,且单层bi_(2)SeO_(5)在拉伸或压缩应变达到6%时均能保持高介电常数,这极大地促进了它与各种二维半导体的集成.本工作证明单层bi_(2)SeO_(5)可以作为高性能二维电子器件良好的封装和介电层.

目的探讨结合使用脑血管3D模型对颅内动脉狭窄患者行介入诊疗宣教的作用。方法选取2022年我院神经内科因颅内动脉狭窄需行介入诊治患者70例,按随机数字分为观察组和对照组,每组35例。颅内动脉狭窄部位包括椎动脉和大脑中动脉。观察组采用术前常规宣教模式结合3D模型进行健康宣教,对照组采用统一宣教单、幻灯片进行常规术前健康宣教。采用自制宣教效果评分量表在宣教前后进行评分,比较两组患者颅内动脉狭窄认识评分、治疗方案知晓评分、就医满意度评分。结果在进行宣教前,两组患者对颅内血管的认知(正常颅内动脉的认识、颅内动脉闭塞的认识、血管狭窄治疗的认识)比较,差异无统计学意义。在实施宣教后,两组患者对颅内血管的认知均升高;但观察组中正常颅内动脉的认识评分、颅内动脉闭塞的认识评分、血管狭窄治疗认识评分、治疗方案知晓评分、就医满意度均明显高于对照组,差异均有统计学意义(P<0.05)。实施宣教干预后,观察组内的大脑中动脉、椎动脉狭窄患者宣教效果评分明显高于对照组,差异有统计学意义(P<0.05)。结论结合3D模型的健康宣教模式可提高患者颅内动脉狭窄诊治的认知,提高就医满意度,提高患者的依从性及颅内动脉狭窄的介入诊治率,从而预防颅内动脉狭窄导致的卒中。
