Advanced Materials Technologies, EarlyView.A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.

Derivatives are essentially integer partitions
, 2000 •Matrix notation simplifies derivatives and relates them to integer partitions.•By differentiation, terms are Dn(f1∘⋯∘fm) are related to terms of Dn+1(f1∘⋯∘fm). By matrix notation, terms of Dn(f1∘⋯∘fm) are related to terms of Dn(f1∘⋯∘fm+1).•Let M(m,n) be

Integers are only Primes and Composites
, 2023 Abstract: This study establishes that integers can exclusively fall into the categories of prime or composite numbers. The rationale behind this arises from the imperative inclusion of (I) negative prime numbers, (II) the acknowledgment of 1 and -1 as prime numbers, and (III) the incorporation of 0 as a composite number within finite and infinite ...

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.

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.
