内容提要:《Nature》杂志隶属于自然出版集团,是一个商业性质的杂志。所以我们经常会看到《Nature》的商业推广等一系列商业操作,毕竟是个盈利的机构,但是《Science》很低调,它毕竟隶属于非营利性机构,但学术影响依然强大无比。
AI, robotics, AI and cognitive science, human-robot interaction, machine learning, deep learning, reinforcement learning, robot learning, artificial neural networks, symbolic reasoning, computer vision, natural language processing, genetic and evolutionary computing, neuro-inspired computing, humanoid robots, swarm robotics, bio-inspired robotics, soft robotics, multi-agent systems and so on.
The formation of our Milky Way can be split up qualitatively into different phases that resulted in its structurally different stellar populations: the halo and the disk components. Revealing a quantitative overall picture of our Galaxy’s assembly requires a large sample of stars with very precise ages. Here we report an analysis of such a sample using subgiant stars. We find that the stellar age–metallicity distribution p splits into two almost disjoint parts, separated at age τ≃ 8Gyr. The younger part reflects a late phase of dynamically quiescent Galactic disk formation with manifest evidence for stellar radial orbit migration;
文|《中国科学报》记者 张晴丹从钻石(金刚石)这种无比坚硬的材料上剥离出大片完整的膜,听起来就像天方夜谭,实际的困难更多。两年时间没有任何进展,香港大学副教授褚智勤组里承接该课题的一位博士后,选择了放弃并离开。没人能做出来!褚智勤也一度想砍掉这个课题。
