    RESEARCH ON DEFORMATION ZONE THICKNESS IN METAL SHEET SINGLE POINT INCREMENTAL FORMING PROCESS by YAO ZiMeng, LI Yan, YANG MingShun, ZHANG Wei, BAI Lang

    Published 2016-01-01
    “…Sheet metal thickness of single point incremental forming deforming deformation zone is one of the important factors affecting parts strength and quality,it is believed that thickness follows the law of cosines and only depends on the size of the forming angle. …”

    Numerical and test study on dynamic characteristics of the tail beam of top coal caving hydraulic supports by WU Mingke, YANG Shanguo, WANG Yao, MENG Bin, YANG Zheng, LIU Houguang

    Published 2025-01-01
    “…Secondly, the acceleration response was decomposed by variational mode decomposition (VMD) to obtain the intrinsic mode function (IMF), and the time domain and frequency domain characteristics of each IMF component were analyzed. Thirdly, the<italic> t</italic>-distributed stochastic neighborhood embedding (<italic>t</italic>-SNE) method was used to reduce the dimension of these features, and the average silhouette coefficient (ASC) of different features was calculated. …”

    DDX1 is required for non-spliceosomal splicing of tRNAs but not of XBP1 mRNA by Teruhiko Suzuki, Satoko Takagi, Junta Funada, Yuka Egawa, Mana Yamakawa, Takahiko Hara

    Published 2025-01-01
    “…Abstract RNA helicase DEAD-box helicase 1 (DDX1) forms a complex with the RNA ligase 2´,3´-cyclic phosphate and 5´-OH ligase (RTCB), which plays a vital role in non-spliceosomal splicing of tRNA and X-box binding protein 1 (XBP1) mRNA. However, the importance of DDX1 in non-spliceosomal splicing has not been clarified. …”

    Social media user geolocalization based on multiple mention relationships by Yaqiong QIAO, Xiangyang LUO, Jiangtao MA, Chenliang LI, Meng ZHANG, Ruixiang LI

    Published 2020-12-01
    “…Aiming at the problem that the existing joint user geolocalization methods based on social media text and social relationships do not sufficiently mine the location correlation between heterogeneous data in social media, a social media user geolocalization method based on multiple mention relationships was proposed.First, a heterogeneous network was constructed by comprehensively considering the mention relationship between users, the user's mention relationship with location indicative words, and the user's mention relationship with geographic nouns.Then, a network simplification strategy was proposed to construct a user-location heterogeneous network that connects users live nearby more closely based on the common mention relationship.After that, a biased random walk algorithm was proposed for the graph node sampling to fully explore the network structure and alleviate the sparsity problem of known locations.Finally, a neural network classifier based on a multilayer perceptron was used to infer the user's location.Experimental results on three representative Twitter data sets of GEOTEXT, TW-US and TW-WORLD show that the proposed method can significantly improve the user geolocalization accuracy.…”

    Fracture Mechanism in Overlying Strata during Longwall Mining by Zhengyi Ti, Jiazhen Li, Meng Wang, Kang Wang, Zhupeng Jin, Caiwang Tai

    Published 2021-01-01
    “…We used the key stratum theory to establish a more realistic thin-plate mechanical model of elastic foundation clamped boundary and study the fracture mechanism of overlying strata during longwall mining. We analyzed the fracture characteristics and factors affecting fracture of the key stratum combined with the Mohr–Coulomb yield criterion. …”
