| 1 | New Discovery of Molybdenite in the Dongping Gold Deposit, Hebei Province, China and its Re-Os Geochronological Implications显示文摘The Dongping gold deposit is located on the northern margin of the North China Craton,and is the largest alkaline pluton-related gold deposit in China(Bao et al.,2014),which is characterized by its large amounts of tellurides.The deposit is largely hosted in the Shuiquangou syenitic complex and consists of auriferous quartz veins and disseminated sulfide ores.It has been extensively studied since its discovery in the 1980s;however the geochronology and genesis of the deposit are still controversial.Nie(1998)considered that the deposit was formed in the Devonian. | WANG Dazhao LIU Jiajun ZHAI Degao ZHEN Shimin WANG Jiang YANG Xi'an | 2019 | Acta Geologica Sinica(English Edition)2019，93，3： | 5 |
| 2 | Real Option and Valuation of CNOOC Ltd显示文摘This paper introduces a real option approach to valuation of oil companies and uses the real option pricing model to value CNOOC Ltd. at the time of its IPO. The empirical result shows that the option pricing value of CNOOC Ltd. exceeds its IPO price at about 21%. | Hao Hong Zheng Shimin Wang Zhen | 2005 | Petroleum Science2005，2，3： | 1 |
| 3 | Characterization of combinatorial histone modifications on lineage-affiliated genes during hematopoietic stem cell myeloid commitment显示文摘造血的干细胞(HSC ) 是能够自强和 multilineage 区别的 multipotent 干细胞。调整 HSC 的 multipotency 和区别的维护的机制仍然是不清楚的。在这研究,我们在 HSC 的 pluripotency 和区别的维护观察了组合 histone 修正模式的角色。HSC (CD34 + CD38 低 ) 从人的脐的绳索血被收集并且导致了在 vitro 区分到承诺的房间。包括 megakaryocytes, granulocytes,和红血球,在 multipotent HSC 和区分的子孙的系特定的抄写因素 / 基因上的 histone 修正被染色质分析 immunoprecipitation 量的聚合酶链反应。我们的结果证明和 H3K4me2, H3K4me3 的底层,和 H3K9me3 和 H3K27me3 的某个水平的高水平的 acH4 和 acH3 的某个水平在在 CD34 + CD38 低 HSC。作为 CD34 + CD38 在系特定的基因上区分进 granulocytes, erythroid 房间,和 megakaryocytes, acH3 的修正层次, acH4,和 H3K4me2 的低 房间仍然是一样或提高,当 H3K4me3 水平极大地被增加时。同时, H3K9me3 和 H3K27me3 修正层次变得更低。在 non-lineage-specific 基因, acH3 和 acH4 层次被减少,并且 H3K4me3 水平在底层留下了,当 H3K9me3 和 H3K27me3 层次急速地被增加时。我们的数据建议组合 histone 修正模式含有在维持 HSC 的 multipotency 并且在 HSC 区别期间保留基因表达式节目的精确性的功能。 | Huarong Tang Shimin An Huanying Zhen Fangping Chen | 2014 | Acta Biochimica et Biophysica Sinica2014，46，10： | 0 |
| 4 | Structure transformation from Sierpiński triangles to chains assisted by gas molecules显示文摘Reversible transformations between fractals and perio dic structures are of fundamental importance for understanding the formation mechanism of fractals.Currently,it is still a challenge to controllably achieve such a transformation.We investigate the effect of CO and CO_(2)molecules on Sierpiński triangles(STs)assembled from Fe atoms and 4,4″-dicyano-1,1′:3′,1″-terphenyl(C3PC)molecules on Au surfaces.Using scanning tunneling microscopy,we discover that the gas molecules induce a transition from STs into 1D chains.Based on density functional theory modeling,we propose that the atomistic mechanism involves the transformation of a stable 3-fold coordination Fe(C3PC)_(3)motif to Fe(C3PC)_(4)with an axially bonded CO molecule.CO_(2)causes the structural transformation through a molecular catassembly process. | Chao Li Zhen Xu Yajie Zhang Jie Li Na Xue Ruoning Li Mingjun Zhong Tianhao Wu Yifan Wang Na Li Ziyong Shen Shimin Hou Richard Berndt Yongfeng Wang Song Gao | 2023 | National Science Review2023，10，7： | 0 |
