Multifunctional Infrared Polarizer Based on Aligned Growth of High‐Density Boron Nitride Nanotubes

Advanced Science, EarlyView.
This paper presents a novel method for the high‐density, aligned growth synthesis and purification of boron nitride nanotubes (BNNTs). The polarization sensitivity and linear dichroism characteristics of BNNTs in the near‐infrared and mid‐infrared bands are comprehensively verified.

Tiling Robotics: A New Paradigm of Shape‐Morphing Reconfigurable Robots

Advanced Intelligent Systems, EarlyView.
Tiling robotics is a novel paradigm of shape‐morphing reconfigurable robots, defining them as polyform‐inspired machines capable of transforming between at least two polymorphic shapes. Various reconfiguration‐enabling and locomotion mechanisms of tiling robots are comparatively analyzed, with the electromechanical developments, along with a proposed ...

Efficient compression of non-manifold polygonal meshes

Computational Geometry, 1999
AbstractWe present a method for compressing non-manifold polygonal meshes, i.e., polygonal meshes with singularities, which occur very frequently in the real-world. Most efficient polygonal compression methods currently available are restricted to a manifold mesh: they require converting a non-manifold mesh to a manifold mesh, and fail to retrieve the ...

Bending performance changes during prolonged canine eruption in saber‐toothed carnivores: A case study of Smilodon fatalis

The Anatomical Record, EarlyView.
Abstract The canine of saber‐toothed predators represents one of the most specialized dental structures known. Hypotheses about the function of hypertrophied canines range from display and conspecific interaction, soft food processing, to active prey acquisition.

Hybrid Coding For Animated Polygonal Meshes

, 2008
A new hybrid coding method for compressing animated polygonal meshes is presented. This paper assumes the simplistic representation of the geometric data: a temporal sequence of polygonal meshes for each discrete frame of the animated sequence. The method utilizes a delta coding and an octree-based method.
