经鼻高流量湿化氧疗与持续气道正压通气治疗阻塞型睡眠呼吸暂停综合征患者的效果比较

第35届中国过程控制会议

作者： Jinchuan Qian Xuerui zhang Songyan Pi Zhihuan Song Bojian Chen xinmin zhang State Key Laboratory of Industrial Control Technology College of Control Science and Engineering Zhejiang University

The surface defect is a key factor affecting the quality of steel products, and have attracted great attention in practical strip steel manufacturing. To accurately analyze key factor for improving product quality, this paper proposes a fine-grained defect information prediction based key factors identification method(FDP). The training of the proposed FDP is supervised by fine-gained defect-related information, which is obtained by a designed defect rate calculation strategy. In addition, after combing with data mode clustering, the final identification results are presented by a two-stage explainable method indicated by importance scores.

Figs(Ficus, Moraceae) and their pollinating fig wasps(Hymenoptera, Agaonidae, Chalcidoidea) are a striking example of obligate mutualism and coevolution. Agaonid females enter the figs to lay their eggs,but also actively or passively transport pollen into the figs at the same time. We examined eight related fig tree species pollinated by host specific Eupristina agaonids to determine the relationships between pollination mode, host pollen, ovule ratios and the ability of the figs to recruit additional non-agaonid pollinators. Uniquely amongst the eight Eupristina species, the pollinator of Ficus curtipes has nonfunctional pollen pockets and no coxal combs, showing that it pollinates passively. Reflecting this, the anther-to-ovule ratio of F. curtipes is unusually *** addition to the agaonids, figs support many species of 'non-pollinating fig wasps'(NPFW) that are typically ovule gallers or parasitoids. These mainly oviposit from outside the figs but there are a few species of NPFW that are like agaonids and enter the figs to oviposit. Two of the eight Eupristina pollinated fig trees support host specific internally-ovipositing fig wasps belonging to the chalcidoid genera Diaziella(Sycoecinae) and Lipothymus(Otitesellinae). Reflecting the trees' pollination modes, these fig wasps act as supplementary pollinators of F. curtipes, but not of Ficus glaberrima, where agaonid pollination is active.

Gravitational waves （GW）, which were predicted by Einstein in 1916 based on the classical theory of General Relativ- ity （GR）, were recently detected by LIGO [1]. This break- through is expected to initiate a novel probe of cosmology, the nature of gravity as well as fundamental physics. In general, signals of GWs can be classified into two categories, which are waves from astro-physical and cosmological sources re- spectively. Accordingly, a number of astronomical and cos- mological experiments are under design across the world [2]. In particular, China is playing a very important role in this field by strengthening a series of fundamental scientific sub- iects, such as cosmic evolution, structure of matter,

Fault classification plays a crucial role in the industrial process monitoring domain. In the datasets collected from real-life industrial processes, the data distribution is usually imbalanced. The datasets contain a large amount of normal data(majority) and only a small amount of faulty data(minority); this phenomenon is also known as the imbalanced fault classification problem. To solve the imbalanced fault classification problem, a novel reinforcement learning(RL)-based cost-sensitive classifier(RLCC) based on policy gradient is proposed in this paper. In RLCC, a novel cost-sensitive learning strategy based on policy gradient and the actor-critic of RL is developed. The novel cost-sensitive learning strategy can adaptively learn the cost matrix and dynamically yield the sample weights. In addition, RLCC uses a newly designed reward to train the sample weight learner and classifier using an alternating iterative approach. The alternating iterative approach makes RLCC highly flexible and effective in solving the imbalanced fault classification *** effectiveness and practicability of the proposed RLCC method are verified through its application in a real-world dataset and an industrial process benchmark.
