Abstract: Permutation entropy (PE) is a widely used metric for quantifying the complexity of time series data. Recent efforts have extended PE to graph signals, resulting in the graph permutation ...
After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He ...
The real news of the President’s Eco nomic Report to Congress last week is not prosperity-for, by now, the whole world knows that the U.S. is fabulously prosperous, and expecting to be more so. The ...

Nagpur: A new north-south highway network would reduce the distance between Delhi and Chennai by 320km, reducing the time to reach the two ends of the country by 15 hours. The reduced distance and ...
Learn how to analyze motion graphs in physics, including position-time and velocity-time graphs. This video explains slopes, areas, and motion behavior to help you clearly interpret real physics ...
Time travel is deterministic and locally free, a paper says—resolving an age-old paradox. This follows research observing that the present is not changed by a time-traveling qubit. It’s still not very ...
The self-talk and rationalisations that lead to driving after drinking are the target of Booze Maths, a campaign by FCB Aotearoa. Informed by contradicting insights that show how 95% of people in New ...
