Purpose:In patients with heatstroke, disseminated intravascular coagulation (DIC) is associated with greater risk of in-hospital mortality. However, time-consuming assays or a complex diagnostic system may delay immediate treatment. Therefore, the present study proposes a new heatstroke-induced coagulopathy (HIC) score in patients with heat illness as an early warning indicator for ***:This retrospective study enrolled patients with heat illness in 24 Chinese hospitals from March 2021 to May 2022. Patients under 18 years old, with a congenital clotting disorder or liver disease, or using anticoagulants were excluded. Data were collected on demographic characteristics, routine blood tests, conventional coagulation assays and biochemical indexes. The risk factors related to coagulation function in heatstroke were identified by regression analysis, and used to construct a scoring system for HIC. The data of patients who met the diagnostic criteria for HIC and International Society on Thrombosis and Haemostasis defined-DIC were analyzed. All statistical analyses were performed using SPSS ***:The final analysis included 302 patients with heat illness, of whom 131 (43.4%) suffered from heatstroke, including 7 death (5.3%). Core temperature (OR = 1.681, 95% CI 1.291 - 2.189, p < 0.001), prothrombin time (OR = 1.427, 95% CI 1.175 - 1.733, p < 0.001) and D-dimer (OR = 1.242, 95% CI 1.049 - 1.471, p = 0.012) were independent risk factors for heatstroke, and therefore used to construct an HIC scoring system because of their close relation with abnormal coagulation. A total score ≥ 3 indicated HIC, and HIC scores correlated with the score for International Society of Thrombosis and Hemostasis-DIC (r = 0.8848, p < 0.001). The incidence of HIC (27.5%) was higher than that of DIC (11.2%) in all of 131 heatstroke patients. Meanwhile, the mortality rate of HIC (19.4%) was lower than that of DIC (46.7%). When HIC developed into DIC, parameters of coagulation dysfunct

追续权制度自产生之日起,就伴随着各种争议。在我国《著作权法》第三次修改过程中,对追续权制度的设立态度几经转变,也体现出理论界和实务界对该权利的需求和顾虑。实际上,在研究追续权制度的正当性基础时,需反思“饥饿的艺术家”神话,还原著作权法公平分配作品利益的使命。在追续权制度构建中,应谨慎对待艺术品价值衡量的特殊性。通过细分艺术品增值利益构成要素,衡量各主体的要素贡献,并以此为据确立艺术品增值利益公平分配的制度理念。在著作权要素分配理论指引下进行规则构建,将追续权明确为一项由艺术家享有的不可转让或放弃的财产性权利。

主要研究分数阶Buck变换器的互补滑模控制(CSMC)方法.首先,基于电子元件实际非整数阶的特性与Riemann-Liouville(R-L)定义相比,Caputo定义更能准确描述Buck变换器模型的结论,建立基于R-L定义的分数阶Buck变换器数学模型.然后,将参数不确定性和外部扰动统一为匹配干扰和不匹配干扰,建立两个分数阶干扰观测器(FDOB)分别实现对干扰及其分数阶导数的跟踪.进而,设计新型分数阶互补滑模面,利用CSMC的高精度和分数阶微积分的记忆特性提升滑模运动的鲁棒性和稳态精度;设计新型趋近律,提升趋近速度的同时保证滑模面邻域内的鲁棒性.最后,基于Mittag-Leffler稳定性理论证明滑模控制器的稳定性.仿真结果验证了所提出FDOB的优越性,控制器相比传统滑模方法能够得到更好的动态性能和更低的稳态误差.

2018年以来,美国针对中国新疆发起一波波舆论战,罗织的罪名令人匪夷所思。文本以政治媒介化理论观照美国涉疆舆论战。政治媒介化指在美西方市场逻辑作用下,政治逐渐依赖、内化媒介逻辑,政治过程受媒介逻辑长期形塑的现象。美国涉疆舆论战通过政治媒介化策略,将其遏制中国的目的隐蔽地转换为一个个“悲情故事”,妄图实现其舆论外交目的。文本深入剖析了美国涉疆舆论战中的政治媒介化过程与策略,揭露了美国涉疆舆论战的真相与本质。
