| 1 | 3D printing of fine-grained aluminum alloys through extrusion-based additive manufacturing:Microstructure and property characterization显示文摘Additive manufacturing(AM)has the potential to transform manufacturing by enabling previously un-thinkable products,digital inventory and delivery,and distributed manufacturing.Here we presented an extrusion-based metal AM method(refer to“SoftTouch”depositionin thefiledpatent)thatis suitablefor making the metal feedstock flowable prior to the deposition through dynamic recrystallization induced grain refinement at elevated temperatures.The flowable metal was extruded out of the printer head like a paste for building dense metal parts with fine equiaxed grains and wrought mechanical properties.Off-the-shelf metal rods were used as feedstock and the printing process was completed in an open-air environment,avoiding pricy powders and costly inert or vacuum conditions.The resulting multi-layer de-posited 6061 aluminum alloys yield strength and ductility comparable to wrought 6061 aluminum alloys after the same T6 heat treatment.The extrusion-based metal AM method can also be advanced as green manufacturing technologies for fabricating novel alloys and composites,adding novel features to existing parts,repairing damaged metal parts,and welding advanced metals for supporting sustainable manufac-turing,in addition to being developed into a cost-effective manufacturing process for the fabrication of dense metal of complex structural forms. | Fengchao Liu Pingsha Dong Abdul Sayeed Khan Yuning Zhang Randy Cheng Alan Taub Zongyi Ma | 2023 | Journal of Materials Science & Technology2023，，8： | 1 |

| 4 | 肝肠循环因子FGF15/19调节胆汁酸代谢从而控制肝脏尺寸大小与肝癌发生显示文摘文章简介肝脏是人体的一个重要代谢器官,它的大小相对于整个个体大小始终维持在一个合适的比例。肝脏如何感知生长起始和停止是肝脏发育、再生以及癌症生物学中一个有待解决的基本科学问题。近年来研究发现,Hippo信号通路在从果蝇到哺乳动物个体的器官发育及大小调控中都起着至关重要的作用。然而具体何种外部因子在调控Hippo信号通路来维持肝脏大小稳态及抑制癌症发生,一直是领域内未解决的问题。 | 姬素渊 刘清许 张世浩 陈青花 王聪 Weiji Zhang Chen Xiao Yuxi Li Cheng Nian Jiaxin Li Junhong Li Jing Geng Lixin Hong Changchuan Xie Ying He Xing Chen Xun Li Zhen-Yu Yin Han You Kwang-Huei Lin Qiao Wu Chundong Yu Randy L.Johnson Li Wang Lanfen Chen Fen Wang 周大旺 | 2020 | 科学新闻2020，，2： | 1 |
| 5 | A rare variant in COL11A1 is strongly associated with adult height in Chinese Han population显示文摘Human height is a highly heritable trait in which multiple genes are involved. Recent genome-wide association studies(GWASs) have identified that COL11A1 is an important susceptibility gene for human height. To determine whether the variants of COL11A1 are associated with adult and children height,we analyzed splicing and coding single-nucleotide variants across COL11A1 through exome-targeted sequencing and two validation stages with a total 20,426 Chinese Han samples. A total of 105 variants were identified by exome-targeted sequencing, of which 30 SNPs were located in coding region. The strongest association signal was chr1_103380393 with P value of 4.8 * 10^(-7). Chr1_103380393 also showed nominal significance in the validation stage(P = 1.21 * 10^(-6)). Combined analysis of 16,738 samples strengthened the original association of chr1_103380393 with adult height(P_(combined)= 3.1 * 10^(-8)), with an increased height of 0.292sd(standard deviation) per G allele(95% CI:0.19-0.40). There was no evidence(P = 0.843) showing that chr1_103380393 altered child height in 3688 child samples. Only the group of 12-15 years showed slight significance with P value of 0.0258.This study firstly shows that genetic variants of COL11A1 contribute to adult height in Chinese Han population but not to children height, which expand our knowledge of the genetic factors underlying height variation and the biological regulation of human height. | Changbing Shen Xiaodong Zheng Jing Gao Caihong Zhu Randy Ko Xianfa Tang Chao Yang Jinfa Dou Yan Lin Yuyan Cheng Lu Liu Shuangjun Xu Gang Chen Xianbo Zuo Xianyong Yin Liangdan Sun Yong Cui Sen Yang Xuejun Zhang Fusheng Zhou | 2016 | Journal of Genetics and Genomics2016，43，9： | 1 |
