Deep neural networks have achieved great success in varieties of artificial intelligent fields. Since training a good deep model is often challenging and costly, such deep models are of great value and even the key commercial intellectual properties. Recently, deep model intellectual property protection has drawn great attention from both academia and industry, and numerous works have been proposed. However, most of them focus on the classification task. In this paper, we present the first attempt at protecting deep semantic segmentation models from potential infringements. In details, we design a new hybrid intellectual property protection framework by combining the trigger-set based and passport based watermarking simultaneously. Within it, the trigger-set based watermarking mechanism aims to force the network output copyright watermarks for a pre-defined trigger image set, which enables black-box remote ownership verification. And the passport based watermarking mechanism is to eliminate the ambiguity attack risk of trigger-set based watermarking by adding an extra passport layer into the target model. Through extensive experiments, the proposed framework not only demonstrates its effectiveness upon existing segmentation models, but also shows strong robustness to different attack techniques.

目的探讨急性心肌梗死合并心源性休克(acute myocardial infarction complicated by cardiogenic shock,AMICS)患者应用静脉-动脉体外膜肺氧合(venous-arterial extracorporeal membrane oxygenation,VA-ECMO)的不同时机对患者预后的影响。方法本研究为前瞻性队列研究,纳入2017年5月至2022年10月就诊于于河南省人民医院接受VA-ECMO支持经皮冠脉介入治疗(primary percutaneous coronary intervention,PPCI)的AMICS患者79例,根据VA-ECMO应用时机,分为早期VA-ECMO组和晚期VA-ECMO组;另纳入同期符合VA-ECMO适应症但未接受VA-ECMO支持的AMICS患者64例为对照组,收集3组患者的人口学基线特征、冠状动脉介入手术资料、围手术期并发症等指标。主要终点事件为1年内生存,次要终点事件为院内及围手术期死亡。采用多因素Logistic及Cox回归模型评估AMICS患者院内及1年内死亡的独立预测因素;采用Kaplan-Meier生存曲线分析3组患者1年内的生存结局。结果共纳入143例AMICS患者,最终136例患者资料纳入分析,其中早期VA-ECMO组42例,晚期VA-ECMO组34例,无VA-ECMO组60例。与晚期VA-ECMO组相比,早期VA-ECMO组患者VA-ECMO后PPCI的比例更高,入院门至导丝通过(door to balloon time,D-to-B)的时间更长、VA-ECMO的支持时间更短、撤机成功率更高,且并发症发生率较低(均P<0.05)。与早期VA-ECMO组相比,无VA-ECMO支持组围术期、院内及1年病死率均明显升高(均P<0.05)。早期VA-ECMO组与晚期VA-ECMO组围手术期及院内病死率差异虽无统计学意义,但晚期VA-ECMO组1年病死率明显较高(P<0.05);晚期VA-ECMO组和无VA-ECMO组相比,围手术期、院内及1年病死率虽降低,但差异均无统计学意义。多因素Logistic及Cox回归模型分析提示,校正干扰因素后,早期VA-ECMO仍是院内(OR=0.244,P=0.015)及1年(HR=0.308,P=0.001)死亡的保护因素;Kaplan-Merier生存曲线显示较晚期VA-ECMO及无VA-ECMO组,早期VA-ECMO组1年内生存率最高。结论与晚期应用VA-ECMO支持PPCI相比,早期VA-ECMO可使AMICS患者获益更大。

To avoid dealing with the zero dynamics limitation brought by the bidirectional power flow through the back-to-back converter in a doubly fed wind generator, a new energy-based modeling and control approach for the grid- side converter is presented. During the modeling process, the grid-side converter is divided into two subsystems with the feedback interconnection structure, and the interactive matrix of the model takes into account the concrete port structure. Then, an energy-based controller is proposed to realize the grid-side control objectives based on the new model. Simulation studies are carried out in MATLAB/Simulink. Comparative results between the proportional-integral controller and the energy-based controller show that the latter one can obtain faster convergence rate and global stability as the load current varies. Moreover, the energy-based controller is also competent for grid-side control when simulated in a 2 MW wind energy conversion system with random wind.

An active crowbar protective circuit is an effective and common approach for low voltage ride through(LVRT) of a doubly-fed induction generator(DFIG). The crowbar resistance value and its switching scheme both have crucial effects on safety recovery. The effects encountered are correlative dependence and interplay so that analyzing them from a single factor, as most existing LVRT control methods would do, obtains a partial optimal solution. This paper combines these two factors toanalyze their coordination effects on the LVRT control,and to also investigate whether the global optimal performance of these factors can be achieved. The principles for resistance selection and the schemes for crowbar switching are discussed first. Next, the coupling relationship is ana-lyzed based on statistical sampling simulation data with different resistance values and various switching *** results demonstrate that their coordination has critical influence on rotor peak current, DC-link voltage and reactive power. The optimal coordination will be different according to specific requirements. Hence the global optimal combination could be achieved when all requirements are taken into consideration.
