Background Medical ozone therapy system was reported to have certain effects on the treatment of severe hepatitis, but its mechanism is not very clear. One of the causes of death of severe hepatitis is complication of renal damage or hepatorenal syndrome. The present study aimed to observe effects of medical ozone therapy system on plasma renin activity （PRA）, angiotensin II （All）, aldosterone （ALD）, renal blood flow and renal function of patients with chronic severe hepatitis and explore mechanisms of medical ozone therapy in the treatment of severe hepatitis. Methods Eighty-five cases with chronic severe hepatitis were randomly divided into ozone therapy group （43 cases） and control group （42 cases）. The patients in the ozone therapy group were treated with basic treatments plus ozone therapy system. Basic autohemotherapy was used. One hundred milliliter venous blood was drawn from each patient, and was mixed with 100 ml （35 pg/ml） medical ozone and then was returned the blood to the patient intravenously, once every other day for 20 days. Only the basic treatments were given to the control group. PRA, All, ALD, renal blood flow and damage to renal function of the two groups before treatment and 20 days after treatment were compared. Survival rates were also compared. Results Twenty days after the treatment, in ozone therapy group, PRA was （1.31±0.12） ng.m^-1.h^1, All （111.25±17.35） pg/ml, ALD （251.31±22.60） pg/ml, which decreased significantly compared with those before treatment （PRA （2.23±0.13） ***^-1.h^-1, All （155.18±19.13） pg/ml, ALD （405.31±29.88） pg/ml, t=4.67-14.23, P 〈0.01 ）, also lower than those of control group 20 days after the treatment （PRA （2.02±0.11） ***^-1.h^-1, All （162.21±15.32） pg/ml, ALD （401.20±35.02） pg/ml, t=4.97-15.61, P 〈0.01）; renal blood flow was （175.15±28.20） ml/min, which increased compared with that before the treatment （（125.68±21.25） ml/min） and was higher than that of control group 20 days after the treatment （（128.59±23.15

自2003年"审计风暴"以来,审计机关的工作受到社会各界的高度重视,公众在期待审计结果公告的同时,也越来越关注审计机关的审计质量。我国政府审计质量不仅取决于审计报告的质量,还取决于审计结果的执行情况,其中审计调查出的主要问题情况是衡量审计报告质量的关键因素。受到可获取数据完整性的限制,本文仅选取审计署特派办2002～2008年审计处理结果的执行情况进行研究,分析了审计结果执行情况与审计处理情况之间的关系。结果表明:司法机关对违规人员的处理能够起到很好的震慑作用;审计结果的执行效果会对政府审计质量产生显著的正面影响。

Multi-model ensemble learning for battery state-of-health estimation:Recent advances and perspectives

引用

Journal of Energy Chemistry 2025年第1期100卷 739-759页

作者： Chuanping Lin Jun xu Delong Jiang Jiayang Hou ying Liang Zhongyue Zou xuesong Mei State Key Laboratory for Manufacturing Systems Engineering Xi'an Jiaotong University Shaanxi Key Laboratory of Intelligent Robots School of Mechanical Engineering Xi'an Jiaotong University Department of Electrical Engineering and Automation Luoyang Institute of Science and Technology School of Mechanical Engineering Hangzhou Dianzi University

The burgeoning market for lithium-ion batteries has stimulated a growing need for more reliable battery performance monitoring. Accurate state-of-health(SOH) estimation is critical for ensuring battery operational performance. Despite numerous data-driven methods reported in existing research for battery SOH estimation, these methods often exhibit inconsistent performance across different application scenarios. To address this issue and overcome the performance limitations of individual data-driven models,integrating multiple models for SOH estimation has received considerable attention. Ensemble learning(EL) typically leverages the strengths of multiple base models to achieve more robust and accurate outputs. However, the lack of a clear review of current research hinders the further development of ensemble methods in SOH estimation. Therefore, this paper comprehensively reviews multi-model ensemble learning methods for battery SOH estimation. First, existing ensemble methods are systematically categorized into 6 classes based on their combination strategies. Different realizations and underlying connections are meticulously analyzed for each category of EL methods, highlighting distinctions, innovations, and typical applications. Subsequently, these ensemble methods are comprehensively compared in terms of base models, combination strategies, and publication trends. Evaluations across 6 dimensions underscore the outstanding performance of stacking-based ensemble methods. Following this, these ensemble methods are further inspected from the perspectives of weighted ensemble and diversity, aiming to inspire potential approaches for enhancing ensemble performance. Moreover, addressing challenges such as base model selection, measuring model robustness and uncertainty, and interpretability of ensemble models in practical applications is emphasized. Finally, future research prospects are outlined, specifically noting that deep learning ensemble is poised to advance ens

Observation of topological charge transformations in acoustic vortex using passive periodic systems

引用

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 140-147页

作者： Di-Chao Chen Xie Liu Changqing xu Da-Jian Wu ying Cheng Xiao-Jun Liu School of Physics and Technology Nanjing Normal University Key Laboratory of Modern Acoustics School of Physics Nanjing University

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.
