Double Trapezoidal Wave Transmitting System with Controllable Turn-Off Edge

Bacterial Pathogenesis: When a turn off is a turn on

Pathogenic bacteria express distinct sets of genes at different stages in their life cycles; inappropriate expression of normally repressed genes during host colonization can interfere with bacterial survival.

Controllable Edge Feature Sharpening for Dental Applications

This paper presents a new approach to sharpen blurred edge features in scanned tooth preparation surfaces generated by structured-light scanners. It aims to efficiently enhance the edge features so that the embedded feature lines can be easily identified in dental CAD systems, and to avoid unnatural oversharpening geometry. We first separate the feature regions using graph-cut segmentation, whi...
