The research and development efforts for the sixth generation(6G) wireless communication are underway to fulfill the growing demands for wireless communications. 6G is expected to become the key enabler for diverse new applications and services [1]. To achieve the excellent performance, 6G will implement extremely large-scale antenna arrays(ELAAs), terahertz [2], and new types of antennas with metamaterials, leading to a paradigm shift for the electromagnetic characteristics.

以翻译作品为接受路径,沈从文的早期文学观受到了《艺术论》的影响,沈从文的小说结构从托尔斯泰的城乡叙事模式中获得了情感、价值上的支持,沈从文将托尔斯泰的形象目标化、模范化,视为理想作家的范型,用以关切一般写作者,又将托尔斯泰的形象化用为应对外界批评/压力和坚持自我道路的精神武器,同时也“见贤思齐”,用托尔斯泰的形象砥砺自己。托尔斯泰被沈从文赞为“最可爱的”“人道主义的”“伟大文学家”,在沈从文接受对象中具有唯一性,与沈从文的情感、精神需求相呼应。理解沈从文对托尔斯泰的接受与转化,能窥见沈从文小说、思想、精神世界中晦暗不明而又真实存在的图景。

Solution processability is a unique property of organic semiconductors. The compact and regular π-π stacking between molecules is paramount in the performance of organic optoelectronic devices. However, it is still a challenge to improve their stacking quality without sacrificing the solution-processability from the aspect of materials design. Here, delicately engineered additives are presented to promote the formation of ordered aggregation of conjugated molecules by regulating their nucleation and growth dynamics. Intriguingly, the long-chain BTP-eC9-4F molecules can realize ordered aggregation comparable to short-chain ones without sacrificing processability. The domain size of BTP-eC9-4F aggregation is enlarged from 24.2 to 32.2 nm in blend *** exciton diffusion and charge transport become faster, contributing to the suppression of recombination losses. As a result, a power conversion efficiency of 19.2% is achieved in D18:BTP-eC9-4F based organic photovoltaics. Our findings demonstrate a facile strategy to improve the packing quality of solution-processed organic semiconductors for high-efficiency photovoltaics and beyond photovoltaics.

目的:观察胰岛素泵持续皮下胰岛素输注(continuous subcataneous insulin infusion,CSII)短期强化治疗2型糖尿病(T2DM)患者的真实世界疗效并探讨疗效关联的影响因素。方法:对本院收治住院治疗的369例T2DM患者开展CSII短期强化治疗,依据治疗第5天的血糖水平,分组为血糖控制达标组和血糖控制不达标组。比较两组患者的糖代谢、生理、生化等方面指标的差异,采用回归统计方法,分析胰岛素泵疗效的影响因素。结果:经过4 d CSII短期治疗,225例(61%)患者血糖控制达标,144例(39%)血糖控制未达标。与达标组相比,未达标组年龄更大,每千克体重每日胰岛素总剂量(TDD)、空腹血糖(FBG)、空腹胰岛素、空腹C肽、胰岛素抵抗指数(HOMA-IR)水平更高,而血磷、胰岛素生长因子1(IGF1)水平则是显著低于达标组。生化指标方面,两组在血脂水平、肝功能、肾功能整体上无显著差异。单因素回归及多因素逐步回归分析结果表明,餐后2 h胰岛素、TDD、血磷是胰岛素泵疗效的关键影响因素。其中,血糖控制达标与血磷呈正相关,与餐后2 h胰岛素、TDD呈负相关。结论:使用胰岛素泵持续皮下输注胰岛素是短期强化治疗T2DM的理想方法,为了获得更满意的血糖控制达标率,临床使用时应更加关注患者的血磷、餐后2 h胰岛素指标水平及TDD。
