Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Spreading factor-based addressing (SFBA)-tree protocol makes use of orthogonal codes (OCs) for the node addressing and routing in wireless sensor networks. No data storage method has been suggested ...

We investigate visual task solution strategies when exploring traditional, orthogonal, and radial node-link tree layouts, four orientations of the non-radial layouts, as well as varying difficulty of ...

As defending Earth from unexpected intruders such as asteroids is part of my expertise , I immediately started receiving questions from my students and colleagues about what was happening. When ...

When scientists spot an asteroid whose trajectory might , they monitor it frequently and calculate the probability that it might collide with our planet.

I was preparing for my early morning class back in January 2025 when I received a notice regarding an asteroid called 2024 YR4. It said the probability it could hit Earth was unusually high.

When scientists spot an asteroid whose trajectory might take it close to Earth, they monitor it frequently and calculate the probability that it might collide with our planet.

At the time of the announcement in January, the asteroid’s impact probability was reported to exceed 1%. The impact probability describes how likely a hazardous asteroid is to hit Earth. For example, ...
