Abstract: As railway transportation grows, the need for rapid and accurate rail profile inspection becomes increasingly critical. Traditional contact-based inspection methods are slow and costly, ...

Abstract: The Iterative Closest Point (ICP) method, primarily used for transformation estimation, is a crucial technique in 3D signal processing, especially for point cloud fine registration. However, ...

In late 2025, confusion arose when interstellar comet 3I/ATLAS and a butterfly shaped solar coronal hole appeared, though scientists confirmed they were unrelated. Samuel Alito raises question over ...

Arizona held on to No. 1 by a single point over fast-closing Michigan in the AP Top 25 on Monday, making it one of the closest races for the top spot in the 78-year history of the men's college ...

Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

Having made its closest approach to the sun on Wednesday October 29, comet 3I/ATLAS will soon be visible from Earth again—before it leaves our solar system. While the comet—first spotted in July—has ...

Interstellar comet 3I/ATLAS on Wednesday reached its closest point to the Sun, a point known as perihelion. Although this cosmic visitor hasn’t been visible from Earth since September, our space-based ...

This study addresses the challenges of anatomical diversity and precision in orthopedic surgery by introducing a novel computational methodology for designing customized osteosynthesis plates. The ...

An interstellar comet that entered our solar system for a brief visit this year has captivated the attention of astronomers from around the world. Comet 3I/ATLAS is the third known interstellar object ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...
