Quantum control of molecular rotation [PDF]
Reviews of Modern Physics, 2018 The angular momentum of molecules, or, equivalently, their rotation in three-dimensional space, is ideally suited for quantum control. Molecular angular momentum is naturally quantized, time evolution is governed by a well-known Hamiltonian with only a ...

Rotation-invariant convolutional neural networks for galaxy morphology prediction [PDF]
arXiv.org, 2015 Measuring the morphological parameters of galaxies is a key requirement for studying their formation and evolution. Surveys such as the Sloan Digital Sky Survey have resulted in the availability of very large collections of images, which have permitted ...

The Journal of the Acoustical Society of America, 2002 Free rotational aerophones such as the bullroarer, which consists of a wooden slat whirled around on the end of a string, and which emits a loud pulsating roar, have been used in many ancient and traditional societies for ceremonial purposes. This article presents an experimental and theoretical investigation of this instrument.

Plane strain problem in a rotating microstretch thermoelastic solid with microtemperatures [PDF]
Theoretical and Applied Mechanics, 2017 A two-dimensional problem in an infinite microstretch thermoelastic solid with microtemperatures subjected to a mechanical source is studied. The medium is rotating with a uniform angular velocity →Ω.

Rotation Equivariant Vector Field Networks [PDF]
IEEE International Conference on Computer Vision, 2016 In many computer vision tasks, we expect a particular behavior of the output with respect to rotations of the input image. If this relationship is explicitly encoded, instead of treated as any other variation, the complexity of the problem is decreased ...
