人工智能应用对企业实现高质量发展和应对风险具有重要意义。本文以2007~2022年A股上市公司为研究对象,考察气候风险感知对企业人工智能创新的影响及作用机制。研究发现,气候风险感知可以显著提高企业的人工智能创新产出。机制检验表明,气候风险感知通过降低企业的融资约束和金融化水平,进而推动企业的人工智能创新。调节分析表明,提高组织韧性能够强化气候风险感知与企业人工智能创新产出之间的正向关系,而较高的媒体监督压力则会抑制这一关系。异质性分析显示,在国有企业与非高科技企业中,气候风险感知对企业人工智能创新的促进作用更为显著。本文的研究为企业应对气候风险提供了微观经验证据,填补了人工智能创新领域的研究空白,为加快构建气候风险管理和防范体系提供有益参考。

陷窝蛋白(caveolin-1,CAV1)是细胞膜上陷窝的基本成分之一,是一种完整的膜蛋白,与CAV1相关的信号转导可调节细胞增殖、侵袭、细胞死亡和脂质代谢,并与多种免疫相关信号有关。化疗是临床上治疗肿瘤、预防肿瘤复发的重要手段,但其在治疗过程中时常发生药物耐药及敏感性降低,这在很大程度上削弱了化疗的治疗效果,而CAV1与肿瘤化疗的耐药性及敏感性关系密切。该文围绕相关机制及研究进展进行综述,并对这一领域未来的发展方向进行讨论,以期为基于肿瘤化疗治疗的临床试验及机制研究提供帮助。

The Zanda basin is one of the very important basins at the north slope of the Himalaya Range. Thus the study of the basin strata will provide critical information about the tectonic evolution of the Himalayan Orogenic Belt. 268 oriented block samples were collected in the 750-m-thick sections of the Zanda ba- sin. The characteristic remanent magnetization (ChRM) was isolated that decays linearly to the origin between 500oC and 690oC for most studied samples. An age range of 9.5―2.6 Ma was estimated from the correlation between our observed polarity column and the Geomagnetic Polarity Time Scale (GPTS). The age of the Zanda basin does not support the models that the South Tibetan Detach system (STDS) is one of the basin controlling faults. Given the sedimentological features in the basin and the tectonic features at the north edge of the basin, the Zanda basin was a half graben that was possibly controlled by the Karakorum fault on the northeast.
