为了提高大数据中多模态信息的检索效果,提出一种基于深度神经网络的多模态信息检索算法。设计深度自编码器,将不同模态的数据投影到一个相同的广义子空间内;利用稀疏编码技术降低共同特征向量的维度,过滤冗余特征和噪声特征;通过去卷积操作和上采样操作对数据进行重建。基于公开模态识别数据集的实验结果表明,该算法能够有效地学习和泛化多模态数据,且在多模态检索实验中也表现出较好的性能。

哈特和奈格里将非物质劳动直接等同于抽象劳动,用非物质劳动力与资本的对抗和分离关系替代劳动力与资本的交换关系,以劳动力价值无法量化为由解构了马克思剩余价值理论。他们认为非物质劳动霸权的确立标志着马克思剩余价值理论的彻底失效。但实际上,非物质劳动既不是抽象劳动,也不是生产劳动,不创造价值和剩余价值,更没有因为劳动力价值无法量化而解构剩余价值的历史唯物主义量化标准。非物质劳动最大的缺陷是只强调非物质劳动的主体性,而忽略其社会关系性。从这一点来看,非物质劳动霸权的确立并没有从根本上改变资本主义经济关系,只不过是信息化时代劳动方式的新变化而已。脱离资本主义生产关系,非物质劳动只能是一个带有人本主义色彩的抽象概念。因此,用非物质劳动解构剩余价值理论完全是一种理论上的倒退。

Microstructure,texture,and mechanical properties of the extruded Mg-2.49Nd-1.82Gd-0.2Zn-0.2Zr alloy were investigated at different extrusion temperatures(260 and 320℃),extrusion ratios(10:1,15:1,and 30:1),and extrusion speeds(3 and 6 mm/s).The experimental results exhibited that the grain sizes after extrusion were much finer than that of the homogenized alloy,and the second phase showed streamline distribution along the extrusion direction(ED).With extrusion temperature increased from 260 to 320℃,the microstructure,texture,and mechanical properties of alloys changed *** dynamic recrystallization(DRX)degree and grain sizes enhanced as the extrusion ratio increased from 10:1 to 30:1,and the strength gradually decreased but elongation(EL)*** the extrusion speed increased from 3 to 6 mm/s,the grain sizes and DRX degree increased significantly,and the samples presented the typical-rare-earth(RE)*** alloy extruded at 260℃ with extrusion ratio of 10:1 and extrusion speed of 3 mm/s showed the tensile yield strength(TYS)of 213 MPa and EL of 30.6%.After quantitatively analyzing the contribution of strengthening mechanisms,it was found that the grain boundary strengthening and dislocation strengthening played major roles among strengthening *** results provide some guidelines for enlarging the industrial application of extruded Mg-RE alloy.

“实践的人化自然观”作为马克思实践哲学与生态思想创造性结合的理论精华,对于推进人与自然和谐共生的现代化建设发挥着不可或缺的作用,这主要体现在三个维度:一是聚集实践的指导思想,从认识论维度肯定人在改造自然环境的实践活动中发挥的主观能动性;二是围绕实践的评判标准,从价值论维度阐明如何消除资本主义私有制引发的异化现象,构筑人与自然和谐共生的现代化关系;三是基于实践的应用方法,从人学维度揭示人在保护自然环境的实践活动中顺应的客观规律。在此基础上,提炼马克思“实践的人化自然观”的当代价值,一方面有利于厘清实践活动中现实的人与自然之间的辩证统一关系,另一方面有助于彰显中国式现代化建设蕴含的绿色发展理念。

Bipolaris sorokiniana is an important disease causing wheat root rot. Different biocontrol strains were screened with the pathogen as the target. A total of 210 strains of bacteria and fungi preserved in the laboratory were preliminarily and secondarily screened by plate confrontation culture. The 17 strains of bacteria and 36 strains of fungi with good bicontrol effect were screened. Eventually, the best fungal strain and the best bacterial strain were obtained. The ITS fragments of fungi were amplified by PCR, and the target band of 571 bp was obtained. The 16 S gene frag-ments of bacteria were amplified by PCR, and the target band of 1 455 bp was obtained. Through morphological observation, the screened strains were identified. Finally, the bicontrol fungus was confirmed as Trichoderma asperellum and the bacterium was Bacillus amylofaciens.
