A lot of things are symmetrical – cats, dogs (bilateral symmetry), planets, stars (spherical symmetry), galaxies, pies (radial symmetry) and a lot more, except for the Universe. If you look really ...

Abstract: This paper reports the rotational morphing capability of a low-power electrothermal kirigami MEMS actuator driven by low-cost pulse-width modulation (PWM) heating, advancing the application ...

As Eckmann put it, the discovery shows “how rich mathematics can be even in a field as well-trod as the study of rotations.” ...

Reflective symmetry is when a shape can be folded in half, with either side of the fold being a mirror image of the other. Rotational symmetry is when a shape can be rotated and it still looks the ...

Mathematicians thought that they understood how rotation works, but now a new proof has revealed a surprising twist that ...

Abstract: The deep unfolding approach has attracted significant attention in computer vision tasks, which well connects conventional image processing modeling manners with more recent deep learning ...
