This was only the second time an orbital class rocket achieved a successful touchdown. The first time was December 21, 2015, when a Falcon 9 was launched from Cape Canaveral and returned to the launching pad [2] （Fig. 1）. In the past, first stage rockets were designed to burn up on reentry. These recovery operations represent impressive achievements in guidance, navigation, and control, and provided some spectacular long range video [1-3] and still pictures of the barge landing from the perspective of the barge [4].展开更多

The goal was to recover the booster for reuse, to reduce cost for subsequent launches, and it was only the second time a Falcon 9 booster was successfully recovered. Video of the booster landing on the ship was striking and demonstrated that recovery was possible at convenient points other than the launch site where the first recovery was achieved.展开更多

Viterbi, of the Viterbi Group, for the creation of the Viterbi Algorithm that is used by the great majority of mobile phones today. This algorithm helped make cell phones practical by focusing on the most likely computing paths in mobile and satellite communications, thereby facilitating the suppression of static in transmissions. This award represents the second rec- ognition of the enormous impact of mobile communications, following the 2013 award to Martin Cooper, Joel S. Engel, Richard H. Frenkiel, Thomas Haug, and Yoshihisa Okumura for their con- tributions to the world＇s first cellular telephone networks. The Draper Prize is one of the world＇s premier prizes for engineering and technology and celebrates innovations that improve the hu- man condition [1 ].展开更多

In order to go into force, the agreement required ratification by 55 countries representing 55% of global emissions. With the agreement on the part of China and the US, representing together 38% of global emissions, obstacles on the path to ratification were markedly reduced. Indeed, on November 4 the required ratifications were reached in order to put the agreement in force 131.展开更多

When pondering the consequences of this upcoming shift, it is appropriate to take a moment to note the passing of Andrew Grove on March 21, 2016 at the age of 79. Grove was the CEO of Intel Corporation from 1987 to 1998, fol- lowing Gordon Moore, and was then its Chair until 2005. As much as anyone, Grove was responsible for transforming Moore＇s Law and the information revolution into realities.展开更多

However, the volume of China＇s OFDI increased rapidly from 2004. There has been an increasing amount of literature on the motivations of China＇s OFD1, but few studies have focused on its location determinants. The present paper aims to fill this gap in the literature by focusing on two important location.factors, natural resources and technology, which are the most important determinants of China＇s OFDI. We use a large panel dataset comprising 132 countries over the period 1991-2009 and the Tobit as well as the Heckman models to establish the relationship between the two location factors and China＇s OFD1. The empirical results suggest that although China ＂s OFD! has been driven by the country＇s desire for a secure supply of natural resources and to attain advanced technology from the developed world, China＇s technology is also a critical attraction for the host developing economies.展开更多
