The Geometry of the Chinese Remainder Theorem

Geometric Summary of the Chinese Remainder Theorem (CRT) For a composite modulus \(N = p1^{e1}\cdots pk^{ek}\), the Chinese Remainder Theorem gives the decomposition \[ \mathbb{Z}/N\mathbb{Z} \cong \prodi \mathbb{Z}/pi^{e_i}\mathbb{Z ...

Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

Advanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

The complexity of the Chinese Remainder Theorem

International Journal of Algebra and Computation
The Chinese Remainder Theorem for the integers asserts that every system of congruence equations is solvable provided that an obvious necessary condition holds. This statement can be naturally generalized to arbitrary algebraic structures within the framework of Universal Algebra. A tuple of congruences of an algebra is called a Chinese Remainder tuple

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...
