In this paper, the issues of stochastic stability analysis and fault estimation are investigated for a class of continuoustime Markov jump piecewise-affine(PWA) systems against actuator and sensor faults. Firstly, a novel mode-dependent PWA iterative learning observer with current feedback is designed to estimate the system states and faults, simultaneously, which contains both the previous iteration information and the current feedback mechanism. The auxiliary feedback channel optimizes the response speed of the observer, therefore the estimation error would converge to zero rapidly. Then, sufficient conditions for stochastic stability with guaranteed performance are demonstrated for the estimation error system, and the equivalence relations between the system information and the estimated information can be established via iterative accumulating ***, two illustrative examples containing a class of tunnel diode circuit systems are presented to fully demonstrate the effectiveness and superiority of the proposed iterative learning observer with current feedback.

从先秦“中”“和”观念发展而来的“中和”思想规约了中国艺术的理想境界与价值鹄的,其中包含着深刻的艺术辩证法。在书法中,“中和”体现在“情感”的中节合度、“法则”的对立统一、“风格”的众体兼备等方面,是各种风格元素交融互渗之后的典范形态。当代书法界应抑制过度追求标新立异的冲动,回归中和的审美心态,书家要实现笔墨与情感的共舞;创作上力避纯视觉化的倾向,依照“中和”的美学圭臬,对作品形式要素之间的矛盾统一关系加以探究与验证;同时应注重书法生态的整体平衡,兼蓄并包,和而不同,以臻至“中和”之艺术胜境。

Calycosin， Astragali Radix most prominent ingredient， has drawn more attention as a result of its ability to treat atherosclerosis(AS). However， the mechanism of action has not been fully elucidated. We investigated the effects of calycosin on bile acid (BA) metabolism and gut microbiome in ApoE-/-mice fed a high-fat diet (HFD). The data showed that the aorta of ApoE-/-mice treated with HFD showed significant atheromatous plaque formation and lipid accumulation， and the levels of TC， TG and LDL-C were significantly increased， while the levels of HDL-C were significantly decreased. Calycosin can substantially regulate lipid levels， thereby alleviating liver lipid deposition induced by atherosclerosis. In addition， 16S rRNA sequencing showed that calycosin treatment has reshaped the gut microbiota disturbed by HFD， in particular， increasing the ratio of Bacteroidetes/Firmicutes， and improving the relative abundance of Bilophila， Desulfovibrio， Bacteroides， Lactobacillus， etc. Meanwhile， targeted metabolomics analysis showed that calycosin treatment significantly modulated CDCA， TCA， LCA， DCA， TDCA and bile acid pool composition， which were associated with atherosclerotic plaque areas. In addition， calycosin treatment also down-regulated FXR protein levels and up-regulated CYP7A1 protein levels in the hepatic. At the same time， calycosin inhibits the ileum FXR/TGR5 signaling pathway， inhibits BA reabsorption， promotes BA excretion， and reduces hepatic cholesterol accumulation by enterohepatic circulation. In addition， we found that calycosin significantly promoted the expression of hepatic ABCA1 and ABCG1 to mediate cholesterol efflux. Meanwhile， calycosin regulates gut microbiota， and Bacteroides， Alistipes， Desulfovibrio， Lactobacillus， Bilophila and Odoribacter are closely related to specific BAs. This enables us to further understand the relationship between BA metabolism and gut microbiota. Calycosin may reduce high-fat diet-induced hepatic cholesterol accumulatio

数字经济时代,通过数字化转型提升产业链韧性,是推动制造业高质量发展、增强制造业国际竞争力的重要举措,也是保障国家产业安全的重要路径。本文分析数字化转型不同阶段对产业链韧性的差异化作用机制,从要素市场化和降低交易成本两大视角探讨如何提升产业链韧性。在理论分析的基础上,基于驱动力、压力、状态、响应(DPSR)模型构建产业链韧性测度指标体系,并采用2002—2020年中国制造业行业面板数据和企业微观数据测度产业链韧性,实证检验数字化转型对提升产业链韧性的影响机制和路径。研究发现,数字化转型整体上能够提升产业链韧性,二者之间呈现非线性的马鞍型关系;要素市场化程度在数字化转型与产业链韧性提升中起到正向调节作用;数字化转型可以通过影响市场渠道性交易成本和融资性交易成本对产业链韧性发挥作用,而监督性交易成本暂无作用。数字化转型与产业链韧性之间的马鞍型关系在不同要素密集度的产业链和产业链韧性不同维度均表现出异质性。加快数字基础设施建设、推动制造业数字化转型,能够提高要素市场化程度、降低交易成本,进而提升产业链韧性和现代化水平。
