Advanced Materials Interfaces, EarlyView.This study investigates the electromagnetic interference shielding performance of a multiphasic nanocomposite consisting of granular magnetic ferrite (α‐LiFe5O8/α‐LiFeO2) and conductive WS2 nanoflakes. It establishes a clear correlation between the shielding performance and relative fractions of the phases with distinct morphologies/dimensionalities ...

Diophantine equations related to quasicrystals: a note
, 2001 We give the general solution of three Diophantine equations in the ring of integer of the algebraic number field ${\bf Q}[{\sqr 5}]$. These equations are related to the problem of determination of the minimum distance in quasicrystals with fivefold ...

On class numbers of algebraic number fields
Journal of Number Theory, 1970 AbstractLet M = Πi = 1t qiei, N = Πj = 1t qjfj be two natural numbers based on the same set of primes q1,…, qt, where the ei are positive.Theorem. There exist infinitely many normal extensions of the field of rational numbers of degree M with class number divisible by N. If M is not equal to 2, there also exist infinitely many nonnormal extensions with

Advanced Photonics Research, EarlyView.Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

The Genus Field and Genus Number in Algebraic Number Fields [PDF]
Nagoya Mathematical Journal, 1967 Let k be an algebraic number field and K be its normal extension of finite degree. Then the genus field K* of K over k is defined as the maximal unramified extension of K which is obtained from K by composing an abelian extension over k2). We call the degree (K*: K) the genus number of K over k.

Techniques and Advances in Ultrafast Photography
Advanced Photonics Research, EarlyView.This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...

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.
