Habitat use of the tapertail anchovy(Coilia mystus Linnaeus, 1758) from the Oujiang River Estuary and the Zhujiang(Pearl) River Estuary was studied by examining the environmental signatures of Sr and Ca in otoliths using electron probe microanalysis. Individuals from the Oujiang River had higher and varied Sr:Ca ratios(expressed as(Sr:Ca)×1 000, 3.83–13.0 average) in the otolith core regions, suggesting that they were born in brackish or sea waters, and that a freshwater habitat might not be necessary for egg hatching and larval ***, individuals from the Zhujiang River had lower Sr:Ca ratios(0.39–2.51 average) in the core regions,suggesting a freshwater origin. After hatching, anchovies from the Zhujiang River migrate downstream to the river estuary close to brackish water. Our results demonstrated varied habitat use for spawning during stages of early life history between the two populations, and suggested that such variations are promoting diversity of life history strategies of this species.

The hepatopancreatic duct (HPD) system links the liver and pancreas to the intestinal tube and is composed of the extrahepatic biliary duct, gallbladder, and pancreatic duct. Haematopoietically expressed-homeobox (Hhex) protein plays an essential role in the establishment of HPD;however, the molecular mechanism remains elusive. Here, we show that zebrafish hhex-null mutants fail to develop the HPD system characterized by lacking the biliary marker Annexin A4 and the HPD marker sox9b. The hepatobiliary duct part of the mutant HPD system is replaced by an intrahepatic intestinal tube characterized by expressing the intestinal marker fatty acid-binding protein 2a (fabp2a). Cell lineage analysis showed that this intrahepatic intestinal tube is not originated from hepatocytes or cholangiocytes. Further analysis revealed that cdx1b and pdx1 are expressed ectopically in the intrahepatic intestinal tube and knockdown of cdx1b and pdx1 could restore the expression of sox9b in the mutant. Chromatin-immunoprecipitation analysis showed that Hhex binds to the promoters of pdx1 and cdx1b genes to repress their expression. We therefore propose that Hhex, Cdx1b, Pdx1, and Sox9b form a genetic network governing the patterning and morphogenesis of the HPD and digestive tract systems in zebrafish.

Ciliates are very important components in most marine ecosystem. They are trophic link between the microbial food web and grazing food chain. In this study, ciliates were collected from 11 sites in the southern South China Sea （SCS） during August 25 to September 28, 2011. Their composition and distribution at the surface and 75m deep depth of the ocean were studied. A total of 30 species belonging to 22 genera were identified, and 22 species of 15 genera were Tintinnids. Eutintinnusfraknoii and E. stramentus were the most common species. The other dominants were strombidiids ciliates including Strombidium conicum and S. globosaneum, which were followed by the tide form, Mesodinium pulex. Ciliates abundance ranged from 46 indL-1 to 368 indL-1 in the open sites, 46-368indL-1 at surface and 73-198indL-1 at 75m deep layer. In the Yongshu reef, ciliates abundance ranged from 167indL-1 to 365 ind L-1 in the water colunm, similar to that in Sanya coral reef waters. Ciliates composition showed obvious difference between surface and 75m deep layer at station S2 （P〈0.05）, while no similar result was observed at other sites. At 75m deep layer, salinity was negatively related to mixed layer depth （P〈 0.05）, but positively to chlorophyll a concentration （P〈 0.05）, indicating that the change of vertical mixing in water column influenced vertical distribution of ciliates in the southern SCS.

Zebrafish hematopoietic stem and progenitor cells（HSPCs） originate from the hemogenic endothelium of the ventral wall of the dorsal aorta（DA） through the endothelial-to-hematopoietic transition（EHT） from approximately 30 to 60 hours post fertilization（hpf）. However, whether other artery sites can generate HSPCs de novo remains unclear. In this study, using live imaging and lineage tracing, we found that the caudal dorsal artery（CDA） in the caudal hematopoietic tissue directly gave rise to HSPCs through *** process initiated from approximately 60 hpf and terminated at approximately 156 hpf. Compared with that in the DA, fewer EHT events were observed in the CDA. The EHT events in the DA and CDA were similarly regulated by Runx1 but differentially influenced by blood flow（i.e., the EHT frequency in CDA was affected to a lesser extent when circulation was compromised in the tnnt2a～（-/-）mutant）. Therefore,the whole artery, including both DA and CDA, was endowed with the ability to produce HSPCs during a much longer time period. Coincidently, the lineage tracing results indicated that adult hematopoietic cells originated from the embryonic endothelium, and those produced later preferentially colonized the adult thymus. Collectively, our study revealed that the CDA serves as an additional source of hematopoiesis, and it shows similar but not identical properties with the DA.

青藏高原低涡(简称高原低涡)和西南涡是影响我国降水的重要天气系统,两者同步变化是引发我国西南和东部地区强降水的重要方式,而两低涡同步变化的物理过程和机理目前尚不清晰。为探究高原低涡和西南涡同步变化的物理机制,选取2020年超强超长梅雨期间一次高原低涡与西南涡同步变化过程,利用ERA5逐小时再分析资料及降水观测资料,分析两涡共存时特殊时间节点所对应的强度、结构等演变特征及位涡收支。结果显示:水平位置不重叠的高原低涡和西南涡也可发生同步变化,即强度变化特征大致相似。两低涡在同步变化之前各自的演变机理不同,但同步变化时两者的演变机理基本一致。具体地,未发生同步变化时,高原低涡主要依靠加热场作用维持东移,西南涡则依靠水平位涡通量散度作用得以维持;两涡同步变化时,两者强度变化相似,演变机理一致,两涡维持主要依靠水平位涡通量散度作用,加热场作用次之。

探讨铣削力三维有限元计算方法,研究航空薄壁零件高速加工切削力变化规律。基于Advant Edge 3D铣削模块,实现对AL7075航空铝合金材料的铣削过程仿真加工并研究铣削力规律。预测不同切削时间下工件及刀具上的温度分布,建立高速铣削参数对铝合金7075铣削力和铣削温度的影响曲线。通过实际铣削试验验证仿真结果的可靠性。研究结果表明:在铣削速度v为250~1 500 m/min,切削速度大于250 m/min时,切削力随切削速度增加而快速下降;当切削速度大于500 m/min时,切削力变化不大,呈微量上升趋势;轴向力FZ在整个速度范围内变化不大;高速铣削参数对铝合金7075铣削力和铣削温度的影响曲线可辅助优化切削加工参数,有助于减小切削过程中刀具的磨损,改善刀具切削状态,提高刀具使用寿命,为预测其他材料的铣削力提供了新的有限元建模方法。
