Abstract: Single-point matching algorithm (point mass filter or particle filter) only uses the current time measurement to calculate the likelihood, which is prone to pseudopeak and false peak. In ...

Early this morning, a severe traffic collision on Route 101 in Candia, New Hampshire left one individual grievously injured, necessitating a swift emergency response that included a life-saving rapid ...

Modified endotracheal tubes designed to reduce patient pneumonia risk failed to improve outcomes compared to standard breathing tubes, researchers report in a new study. Results of the randomized ...

In a message posted on X and in remarks to attendees of the Builders AI Forum 2025, the first American pope called on AI developers to treat their work as a moral vocation rather than a purely ...

Surprisingly the page is missing a nice way of computing the next term in F_n without any recursion. Given two consecutive entries a/b and c/d, the next term p/q is given by p = ((n + b) // d) * c - a ...

Researchers at the University of Kent, UK, introduced LiteRBS (Lightweight and Rapid Bidirectional Search), a novel grid-based pathfinding algorithm designed for efficient and scalable navigation in ...

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 ...

Maintaining an open airway is a critical priority in emergency medicine. Without the flow of oxygen, other emergency interventions can become ineffective at saving the patient’s life. However, ...

The Independence-variant littoral combat ship USS Gabrielle Giffords leads a formation with the unmanned surface vessels Ranger and the USV Mariner during Integrated Battle Problem 23.2, on Sep. 7, ...

Reinforcement learning (RL) plays a crucial role in scaling language models, enabling them to solve complex tasks such as competition-level mathematics and programming through deeper reasoning.

Abstract: This paper proposes a fast multi-spacecraft rendezvous sequence mission planning algorithm based on neural combinatorial optimization (NCO) and deep reinforcement learning (DRL). The ...
