为了全面分析我国市售牛油果油和葡萄籽油的品质，为食用油产品开发提供指导，采集了市售牛油果油、葡萄籽油主流产品各9种，全面分析其理化品质、危害物风险和营养素水平，并与常见大宗食用油营养素水平进行对比。结果表明：在理化品质上，两种植物油的不同产品存在一定差异，但均符合国家标准；两种植物油苯并\[a\]芘、塑化剂含量均符合国家标准，88.9%的产品反式脂肪酸含量控制在1%以内，但国际前沿关注的3-氯丙醇酯和缩水甘油酯存在超标风险；牛油果油的主要营养素为油酸、角鲨烯、植物甾醇、维生素E，葡萄籽油的主要营养素为亚油酸、植物甾醇、维生素E、谷维素。 In order to comprehensively investigate the product quality of avocado oil and grapeseed oil in Chinese market, and provide guidance for the development of edible oil products，9 different products of each kind of oil were collected. Their physicochemical quality, risk of hazards, and nutrient level were fully analyzed, and their nutrient level was compared with the common bulk edible oil. The results showed that in terms of physicochemical quality, there were certain differences between different products of the two vegetable oils, but both met the national standards. The content of benzo\[a\]pyrene and plasticizer in the two vegetable oils met the national standards, and the content of trans fatty acid in 88.9% of the products was controlled within 1%, but the 3-chloropropanol ester and glycidyl ester, which were concerned by the international frontier, had the risk of exceeding the standard. The primary nutrients in avocado oil were oleic acid, squalene, phytosterol and vitamin E, and in grapeseed oil were linoleic acid, phytosterol, vitamin E and glutathione, respectively.

目的 探讨双重阻断式程序护理联合信息化延续护理预防剖宫产术后下肢深静脉血栓 (DVT) 的 临床效果。方法 选择 2022 年1月至 2023 年1月该院收治的136例剖宫产产妇作为研究对象,根据产妇个人意 愿,将其分为研究组 (62例)和对照组(74例)。对照组产妇采用常规护理联合信息化延续护理,研究组采用受重阻 断式程序护理联合信息化延续护理。比较2组凝血功能指标[活化部分凝血活酶时间 (APTT)、凝血酶原时间 (PT) 及纤维蛋白原 (Fib)] 及 DVT 阳性体征发生情况。结果 2组入院时 APTT、PT 、Fib水平比较,差异均无统 计学意义 (P>0.05)。2组术后2dAPTT、PT 水平低于入院时,Fib水平高于入院时,差异均有统计学意义(P< 0.05)。术后 2d,研究组 APTT、PT 水平高于对照组,Fib水平低于对照组,差异均有统计学意义 (P<0.05)。研究 组 DVT 阳性体征总发生率为11.29%,明显低于对照组的25.68%,差异有统计学意义(P<0.05)。结论 双重阻 断式程序护理联合信息化延续护理可有效改善剖宫产术后产妇凝血功能指标,降低 DVT发生率。 [ABSTRACT FROM AUTHOR]

The traditional nonnegative matrix factorization methods are based on single-layer model. The deep nonnegative matrix factorization methods are based on the mathematical theory, ignoring the actual spectral mixing process of materials. This paper started from the physical process of spectral mixing, combining the advantages of traditional nonnegative matrix factorization models and deep learning. Aiming at the problem that the deep nonnegative matrix factorization methods ignore the actual spectral mixing process of materials, the spectral mixing process is reversed from the physical spectral mixing process. Furthermore, considering the sparsity and spatial smoothness of the distribution of the endmembers in the two-dimensional space, the total variation and sparsity regularized deep nonnegative matrix factorization based on the endmember matrix is proposed. This paper verified the effectiveness of the proposed method through synthetic experiments and real data experiments, which is compared with five classical hyperspectral unmixing methods. Compared with SDNMF-TV, SAD and RMSE are reduced. The results both in the synthetic experiments and the real experiments shows that the method in this paper achieves the best unmixing results.

Aiming at the problem of long time-consuming and high equipment energy consumption for task scheduling in mobile cloud computing environment,this paper proposed a task scheduling strategy based on improved bird swarm algorithm(IBSA).Firstly,the method constructed a mobile cloud task scheduling model based on energy consumption and time.Secondly,it proposed adaptive sensing coefficients and social coefficients to prevent the algorithm from falling into a local optimum.It optimized the learning factors to optimize flight behavior and ensure that superior ability.Finally,it used the task scheduling objective function as the fitness function of the bird group to participate in the iterative updating of the algorithm.The simulation results show that the IBSA has good effects in mobile cloud computing task scheduling compared with ant colony algorithm,particle swarm algorithm,whale algorithm and bird swarm algorithm,which can effectively save time and reduce energy consumption.
