Abstract: This paper presents a system to obtain X-ray phase contrast images using a Commercial-Off-The-Shelf, low cost, CMOS Image Sensor as a direct radiation detector. The 5.2 μm pixel pitch allows ...

This repository contains the code for the paper "No-Reference Quality Assessment of Contrast-Distorted Images using Contrast Enhancement", and presents the results on CCID2014，CID2013，CSIQ and TID2013 ...

Differential phase contrast scanning transmission electron microscopy (DPC STEM) measures Coulomb or Lorentz deflections of the STEM incident electron beam, visualizing electromagnetic fields ( Figure ...

And 2D materials where diffraction from the surface is used to enhance contrast and demonstrate a particularly interesting contrast mechanism. Beams of noble gasses, have been used for surface science ...

We also help governments translate them into national laws to ensure refugees are protected and can exercise their rights. The core principle of the 1951 Convention is non-refoulement, which asserts ...

The plant cell wall is a dynamic network of several biopolymers and structural proteins including cellulose, pectin, hemicellulose and lignin. Cellulose is one of the main load bearing components of ...
