subject to reasonable assumptions about the emission (equivalently we have an upper limit oflPlanck/1.2 on the length scale of the effect). Our results disfavour quantum-gravity theories3,6,7in which the quantum nature of space–time on a very small scale linearly alters the speed of light. ...
view rawCell1+2.ipynbhosted with byGitHub In the next step, you load the ECG data. The length of the query is rather short with 421 entries, yet the stream exhibits roughly 20 million time ticks. A first inspection of the full query (blue) and the initial 1000 values of the stream...
The quantum speed limit (QSL) is a theoretical lower bound of the time required for a quantum system to evolve from an arbitrary initial state to its orthogonal counterpart. This figure can be used to characterize the dynamics of open quantum systems, in
We propose an experimental study on the influence of the tip speed ratio on the spatial development of a wind turbine wake. To accomplish this, a scaled wind turbine is tested in a wind tunnel, and its turbulent wake measured for streamwise distances bet
In general, a good internet speed is at least 100 megabits per second (Mbps) for downloads, and ideally for uploads as well. However, many people are satisfied with slower uploads of around 35 Mbps. That said, a “good” speed really depends on how you and your family use the internet...
