Our guest today is Charlie Hamilton, a photographer who spent a month and a half in the Amazon. He’s going to share with us the challenges and responsibilities of his work. Charlie, the Amazon people have rarely seen people from outside, and you look so different. How do you approach ...
WeChat, the ubiquitous messaging app, is being used for an ever longer period of time and is growing into a lifestyle choice embedded into daily activities and interactions, a new survey has found. Lawmakers call for enhanced supervision on mapping drones China's lawmakers on Tuesday deliberated...
We deduce the Hopf bifurcation existence parameter domains described in equation (19) at first, then use elliptic functions and elliptic integration to calculate these parameter domains with different m's (m is the resonant order of period orbits) shown as Fig.1. In order to verify that our ...
The proposition that the coherence length of de Broglie wave packets remains unchanged even though the length of the packets increases upon propagation is ... AG Klein,GI Opat,WA Hamilton - 《Physical Review Letters》 被引量: 120发表: 1983年 Observation of atom wave phase shifts induced by va...
5a,b). Interestingly, and consistent with expert human assessment6, the distribution width of predicted embryonic stages increased after the beginning of the segmentation period (blue and purple; Fig. 3b and Extended Data Fig. 5a,b), whereas average similarities decreased during embryonic development...
