LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

REVERSIBLE DATA HIDING AND REVERSIBLE AUTHENTICATION WATERMARKING FOR BINARY IMAGES [PDF]

, 2008
Data hiding is a technique used to embed a sequence of bits in a host image with small visual deterioration and the means to extract it afterwards. Reversible data hiding allows, in addition, recovering the original cover-image exactly.

A capacity-enhanced reversible data hiding scheme based on SMVQ [PDF]

, 2014
In recent years, there are many reversible data hiding schemes proposed. Most schemes are guaranteed that the original cover image can be reconstructed completely. When the secret data are hidden in the compression image, the receiver need to extract the
