Advanced Science, EarlyView.A dual‐chamber origami prismatic actuator is designed by integrating straight‐curved creases with folded partitions, enabling large‐range, multidirectional motions and enhanced structural stability. The actuator exhibits anisotropic stiffness and multiple actuation modes, and is fabricated via single‐material, one‐step molding.

Topology-controlled Laplace–Beltrami operator on point clouds based on persistent homology
Graphical ModelsComputing the Laplace–Beltrami operator on point clouds is essential for tasks such as smoothing and shape analysis. Unlike meshes, determining the Laplace–Beltrami operator on point clouds requires establishing neighbors for each point.

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels
Advanced Science, EarlyView.Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...

On the Laplace-Type Transform and Its Applications
AxiomsUsing the Laplace transform and the Gamma function, we obtain the Laplace-type transform, with the property of mapping a function to a functional sequence, which cannot be realized by the Laplace transform. In addition, we construct a backward difference

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution
Advanced Science, EarlyView.The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

Advanced Science, EarlyView.We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Osmotically Tunable Microdroplets Enable Amplification‐Free CRISPR Detection of Gene Doping
Advanced Science, EarlyView.A novel amplification‐free clustered regularly interspaced short palindromic repeats/CRISPR‐associated protein (CRISPR/Cas) 12a assay is integrated with osmotically shrinkable double emulsion droplets for the rapid and ultrasensitive detection of gene doping.

On the projections of Laplacians under Riemannian submersions
International Journal of Mathematics and Mathematical Sciences, 2001 We give a condition on Riemannian submersions from a Riemannian manifold M to a Riemannian manifold N which will ensure that it induces a differential operator on N from the Laplace-Beltrami operator on M.
