In a product optimization design strategy, it is very important to carry out product attention mining and prediction of user satisfaction change law based on user preference evaluation information. Most of the existing research adopts a scale-based semi-structured data analysis model, which ignores the multi-dimensional nonlinear decision-making attributes of the evaluation process, especially the coupling problem between differential kansei images. In this regard, a heterogeneous emotional theme clustering simulation process is developed for unstructured data, and the web crawler is first used to obtain the user’s online comment text. Then, with the help of Word2vec, the text is numerically encoded, and the sentiment binary classification judgment is completed by the sentiment analysis model, and the positive and negative sentiment datasets are established. Then, the BTM is used to carry out heterogeneous emotional theme clustering. Finally, the quantitative results of multi-dimensional evaluation indicators are output. The results show that the constructed simulation process can accurately judge dichotomous (the reliability test is greater than 0.85), and the topic clustering results are in line with the product optimization strategy. © 2024 Northeast University.

热木星(hot Jupiter, HJ)和温木星(warm Jupiter, WJ)的起源,一直是系外行星研究领域的未解之谜.尽管有科学家认为热木星可能在本地形成^([1~3]),但也有学者认为这些轨道周期很短的“大个子”,应该像太阳系的木星一样只能在远离恒星的偏远之地形成——只有在那里,才有足够的“粮食”供它们生长.但与木星不同的是,它们获得了宿主恒星的某种“眷顾”——经历了某种轨道迁移过程——从而进入了“人生的上升通道”,最终来到了靠近宿主恒星的中心地带.

在面向来华留学生开设的中国国情类课程中,在教学内容和教学方法上均存在古代史与古代文化知识占比偏大,而介绍当代中国的内容占比偏小、涉及面偏窄、教学思路单一陈旧等问题。在全球化与中国综合国力全面提升的背景下,国情课程教学应进一步增加当代内容比重,凸显“当代性”。在明确“当代性”内涵基础上,将改革开放至今40余年的中国社会发展作为国情教育的重点内容;除介绍当代中国的物质文明和精神文明成就以外,还应把握文明共存的时代趋势,阐释当代中国对于世界各领域的参与、贡献,强调中国和平共处、求同存异的原则,引导学生从跨文化和整体性的视角加深对中国的理解;教师本人应克服思维定式,在教学内容、思维和手段上寻求“当代性”。

为研究受重复采动影响下沿空留巷巷道剧烈的底鼓发生机理及治理方法,以芦家窑煤矿二采区84206工作面运输顺槽为工程案例,通过理论分析、数值模拟等方式分析了该矿84206运输顺槽底鼓特征及影响因素。结果表明:工作面回采后,沿空留巷顶板应力经过2次应力分流,在煤体和充填体上形成非对称分布的应力双峰现象;基于朗肯土压力理论和数值模拟,非对称应力分布是造成沿空留巷非对称底鼓的主要原因,最大底鼓量靠近垂直应力低的采空区一侧;提出了巷道底板注浆锚索+喷浆密闭的支护方案,现场试验表明该技术有效地控制了沿空留巷巷道底鼓的变形。

随着平台经济垄断化趋向愈加明显,平台经济中的劳动关系呈现出多元性、复杂性与隐蔽性等特征,特别是随着消费者等新主体的加入,平台经济中的劳动关系形成了多边、多行为主体的交互博弈格局。诸多理论与实践表明,平台企业、劳动者与消费者三个行为主体的交互博弈过程并非是“共享均利”的和谐共生状态,反而是在平台企业的垄断操控下演变成了平台企业单方的“垄断套利”非均衡状态,集中表现为平台企业与劳动者之间的“隐蔽操控—弱势从属”,消费者与劳动者之间的“协同监控—被动服务”,以及平台企业与消费者之间的“精准套利—粘性依存”等特征。本文认为,应从国家规制、工会维权以及舆论引导等多个方面协同发力,多措并举推动平台劳动关系回归至“共享均利”状态,促进各行为主体间和谐共生、协同共赢,才是今后平台经济反垄断的治理方向。

目的:探讨TP53等位基因状态在骨髓增生异常综合征(MDS)患者中的临床意义。方法:回顾性分析2019年1月至2021年12月在苏州大学附属第一医院进行二代测序的858例MDS患者的临床资料。结果:患者中位年龄为52岁,中位随访时间为23.8(0.4-109.6)个月。401例患者(46.7%)至少有一个染色体异常,其中,复杂核型106例,单体核型78例。共发现103例TP53突变,突变率为12%。与TP53野生型患者相比,各种类型的染色体异常情况明显更多见于TP53突变型患者(均P0.05)。TP53野生型患者的中位OS未达到,野生型、单等位基因和双等位基因TP53突变患者中位OS比较存在明显差异(P<0.001)。多因素Cox回归分析结果显示,双等位基因TP53突变为患者不良预后的独立预测因子(HR=2.808,95%CI:1.487-5.003,P=0.001),而单等位基因TP53突变与野生型TP53不是。结论:伴TP53突变的患者预后不良,双等位基因TP53突变相比单等位基因TP53突变预后更差,并且独立地影响MDS患者的预后。
