Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Video Object Tracking Mechanism
IOSR Journal of Computer Engineering, 2014 The video object mechanism is based on the appearance representation of the object. Tracking objects in a video has applications in video surveillance and other some applications. In previous method does not handle the case of full occlusion. The case of full occlusion can be handled by setting an LSK similarity threshold, which stops tracking when the

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation
Advanced Functional Materials, EarlyView.Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

An Improved Kernelized Correlation Filter for Extracting Traffic Flow in Satellite Videos
Journal of Advanced TransportationIn satellite video vehicle tracking, due to the tracking failure and tracking loss caused by similar characteristics of the target and obstacle occlusion, respectively, the traffic flow extraction accuracy is reduced. To address these issues, an improved

Gourd‐Inspired Design of Unit Cell with Multiple Gradients for Physiological‐Range Pressure Sensing
Advanced Functional Materials, EarlyView.Gourd‐shaped micro‐dome arrays with coordinated modulus, conductivity, and geometric gradients co‐optimize sensitivity and linearity in piezoresistive tactile sensors. Under pressure, a solid upper dome embeds into a porous lower dome, triggering rapid contact‐area growth and series‐to‐parallel conduction, enabling unsaturated, intensity‐resolved ...
