Stress‐guided photo‐programming of cholesteric liquid crystal elastomers for 2D‐to‐3D shape–color information encoding

Responsive Materials, EarlyView.
We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Ultrahigh-fidelity full-color holographic display via color-aware optimization

PhotoniX
Holographic display offers the capability to generate high-quality images with a wide color gamut since it is laser-driven. However, many existing holographic display techniques fail to fully exploit this potential, primarily due to the system’s ...

Real-time optical micro-manipulation using optimized holograms generated on the GPU

, 2010
Holographic optical tweezers allow the three dimensional, dynamic, multipoint manipulation of micron sized dielectric objects. Exploiting the massive parallel architecture of modern GPUs we can generate highly optimized holograms at video frame rate ...

Effects of gill and muscle biopsies on the short‐term behaviour, exercise performance and survival of juvenile lake trout (Salvelinus namaycush)

Journal of Fish Biology, EarlyView.
Abstract Non‐lethal biopsy is a valuable tool for gaining insight into the physiological status of fish in the wild and for predicting their subsequent behaviour and survival. However, linking the insights from biopsy to post‐release behaviour relies on the assumption that the biopsy itself has no meaningful impact on post‐release behaviour or survival

Exploring the Relationship Between a PST's Written Noticings of Student Mathematical Reasoning and Their Reported and Actual Viewing of a 360 Video

School Science and Mathematics, EarlyView.
ABSTRACT An essential aspect of mathematics teacher education is the development of professional noticing. A 360 video is a new technology that can aid in developing mathematical teacher noticing. This study examines the relationship between preservice teachers' noticing of mathematical student thinking and the variation in their physical focusing ...
