Earthshaker: A mobile rescue robot for emergencies and disasters through teleoperation and autonomous navigation

To deal with emergencies and disasters without rescue workers being exposed to dangerous environments, this paper presents a mobile rescue robot, Earthshaker. As a combination of a tracked chassis and a six-degree-of-freedom robotic arm, as well as miscellaneous sensors and controllers, Earthshaker is capable of traversing diverse terrains and fulfilling dexterous manipulation. Specifically, Earthshaker has a unique swing arm—dozer blade structure that can help clear up cumbersome obstacles and stabilize the robot on stairs, a multimodal teleoperation system that can adapt to different transmission conditions, a depth camera-aided robotic arm and gripper that can realize semiautonomous manipulation and a LiDAR aided base that can achieve autonomous navigation in unknown areas. It was these special systems that supported Earthshaker to win the first Advanced Technology & Engineering Challenge (A-TEC) championships, standing out of 40 robots from the world and showing the efficacy of system integration and the advanced control philosophy behind it.     

鄂尔多斯盆地长7储层致密油水平井CO2补充能量与吞吐参数优化

长7储层是鄂尔多斯盆地主要的致密区块,近一半的致密油分布其中。针对长7储层开采渗透率低、开采难度大、依靠弹性开采产能较低、能量衰竭较快等问题,通过数值模拟的方法,构建水平井分段压裂数值模拟模型,首先对比不同吞吐方式对油田产能的影响,优选出CO₂吞吐为首选的补充能量方式。其次对井网形式、井网参数及吞吐参数进行优化研究。最终优选出合适的吞吐方案,达到提高生产效率的目的。结果表明,该储层的最优注采吞吐参数为：周期注入量为2 673 t、注入压力为21 MPa、注入速度为90 t/d、焖井时间为10 d。研究对鄂尔多斯盆地长7储层提高采收率具有一定的参考意义。     

满江红鱼腥藻glnA基因上游调控区的克隆及其序列分析

以满江红鱼腥藻（Ａａｃ）提取总ＤＮＡ为模板,通过ＰＣＲ技术,扩增得到其谷氨酰胺合成酶基因（ｇｌｎＡ）上游区．经酶切得到４０９ｂｐ的片段,并将其连接到ｐＢｌｕｅｓｃｒｉｐｔⅡｋｓ＋上测序．将测序结果与Ａｎａｂａｅｎａ７１２０调控序列比较,有９８２％的同源性．在上游调控中也具有ｎｉｆｌｉｋｅ和Ｅ．ｃｏｌｉｌｉｋｅ启动子,值得注意的是,调节蛋白ＶＦ１的结合位点正好位于ｎｉｆｌｉｋｅ启动子上．所克隆的片段不但对蓝藻固氮、泌氨的基因调控研究具有意义,也对表达载体的构建具有实用价值．     

Structural and expressional analysis of a cDNA that expresses predominantly in rice stamens

The development of stamen is an important stage during the sexual reproduction in higher plants. Studying the genes that predominantly or even specifically expressed in stamens will aid in undestanding the molecular mechanism of stamen development. The structure of a rice CHS-like gene (D5) which predominantly expressed in anthers has been analysised, showing high structural similarity with two other anther-specific genes (A1 and BA42) fromBrassica napus. Northern analysis also reveals that the three genes share a similar expression pattern and that the expression of D5 may relate to the early development of pollens. It is concluded that D5, A1 and BA42 represent a group of diverged CHS-like genes which are related to stamen development.
