The problem of delay-dependent robust stability for uncertain linear singular neutral systems with time-varying and distributed delays is investigated. The uncertainties under consideration are norm bounded,and possibly time varying. Some new stability criteria,which are simpler and less conservative than existing results,are derived based on a new class of Lyapunov-Krasovskii functionals combined with the descriptor model transformation and the decomposition technique of coeffcient matrix and formulated in...

西南地区突发性重大地质灾害常发生于深切河谷区,在应急抢险过程中,存在人员难到达、地面调查与监测困难、灾害持续变形破坏造成的危害大等问题。以西藏自治区江达县白格滑坡和四川丹巴县阿娘寨滑坡应急抢险为例,应用边坡雷达对白格滑坡残留体和阿娘寨滑坡复活体进行应急监测和变形特征研究。结果表明:通过边坡雷达获取各测点的累计视向变形量、变形速率、变形加速度等监测数据绘制监测区变形云图和监测曲线,判识滑坡区变形破坏及发展趋势、研判各变形区所处的变形演化阶段,快速对临滑破坏区进行识别与预报。边坡雷达能对突发性重大地质灾害开展非接触式全天候实时监测,既能实时掌握灾害变形特征,也保证了监测人员安全,对今后类似的突发性地质灾害应急监测和预警预报具有参考借鉴意义。

Gut microbiota have been reported to play an important role in the occurrence and development of malignant tumors. Currently, clinical studies have identified specific gut microbiota and its metabolites associated with efficacy of immunotherapy in multiple types of *** investigations have elucidated that gut microbiota modulate the antitumor immunity and affect the efficacy of cancer immunotherapy. Certain microbiota and its metabolites may favorably remodel the tumor microenvironment by engaging innate and/or adaptive immune cells. Understanding how the gut microbiome interacts with cancer immunotherapy opens new avenues for improving treatment strategies. Fecal microbial transplants, probiotics, dietary interventions, and other strategies targeting the microbiota have shown promise in preclinical studies to enhance the immunotherapy. Ongoing clinical trials are evaluating these approaches. This review presents the recent advancements in understanding the dynamic interplay among the host immunity, the microbiome, and cancer immunotherapy, as well as strategies for modulating the microbiome, with a view to translating into clinical applications.
