Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale
Advanced Optical Materials, EarlyView.Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Dictionary-Based Data Hiding Using Image Hashing Strategy
, 2013 [[abstract]]This paper proposes a novel data hiding framework based on image hashing strategy. First, the best-matching blocks for each cover image block are searched in the existing database, which can be generated by the codebook of vector quantization

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals
Advanced Optical Materials, EarlyView.A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space
Advanced Robotics Research, EarlyView.A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
