Key task in computer vision and graphics gets a boost

Key task in computer vision and graphics gets a boost
Kanazawa, Japan – Non-rigid point set registration is the process of finding a spatial transformation that aligns two shapes represented as a set of data points. It has extensive applications in areas such as autonomous driving, medical imaging, and robotic manipulation. Now, a method has been developed to speed up this procedure.
In a study published in IEEE Transactions on Pattern Analysis and Machine Intelligence, a researcher from Kanazawa University has demonstrated a technique that reduces the computing time for non-rigid point set registration relative to other approaches.
Previous methods to accelerate this process have been computationally efficient only for shapes described by small point sets (containing fewer than 100,000 points). Consequently, the use of such approaches in applications has been limited. This latest research aimed to address this drawback. ....

Extinct Niobium Isotope Reveals Long-Kept Secrets of Solar System

Extinct Niobium Isotope Reveals Long-Kept Secrets of Solar System
Evidence of extinct radionuclides like Niobium-92, which formed before the birth of our Solar System, has been identified in meteorites. Using this evidence, scientists at Tokyo Institute of Technology (Tokyo Tech) ETH Zürich, National Institute of Polar Research, and Konkoly Observatory pinpointed the initial abundance of Niobium-92 by studying rare rutile and zircon minerals from meteoritic fragments. This allowed them to date events in the early Solar System with greater precision and provide constraints on the production of Niobium-92 in different types of supernova explosions.
When an element has a surplus of protons or electrons, it becomes unstable and sheds these additional particles as radiation until it reaches stability. Niobium-92 ( ....

Scanning tunneling microscopy reveals origins of stable skyrmion lattices

Scanning tunneling microscopy reveals origins of stable skyrmion lattices
Figure 1: The crystal structure of gadolinium ruthenium silicide, which can host a square lattice of swirling magnetic skyrmions (orange = gadolinium; green = ruthenium; blue = silicon). Modified from Ref. 1 and licensed under CC BY 4.0 © 2021 Y. Yasui et al.
RIKEN physicists have discovered how interactions between electrons can stabilize a repeating arrangement of swirling magnetic patterns known as skyrmions, which could help to further exploit these structures
1.
The spin of an electron causes it to behave like a miniature magnet. In a skyrmion, many of these spins are arranged in a swirling pattern that resembles a tiny tornado. Skyrmions are highly promising as a means of carrying information in a new generation of high-density, low-energy data-storage devices. ....

Kevin Costello: Exploring intersections of math and music

Massachusetts Institute of Technology
“Good night, Kev. Think big.” His father smiled, tucking him in and closing the door. The next day, 13-year-old Kevin Costello III arrived for the first time to MIT. But his visit wasn’t for the average campus tour. Costello, a three-time Rubik’s Cube national champion, had come to compete.
Tension grew in the competition room as the final round approached. Costello knew he had less than six seconds to solve the cube drawing from the 300 solving algorithms he had memorized. To stay calm, he turned toward a reliable source of comfort – music. Popping in his headphones, he felt his chest relax as he gained the confidence to pull off another win. ....
