Magnetic performances of β-Ti68.75Nb25X6.25 (X=Fe, Mo, Sn, Ta, Zr) alloys were investigated with first-principles method. The results indicate that the alloys of TiNbSn, TiNbTa, and TiNbZr exhibit interestingly strong magnetism. The magnetic propert

A new imaging modality framework, called elasto-mammography, is proposed to generate the elastograms of breast tissues based on conventional X-ray mammography. The displacement information is extracted from mammography projections before and after br

Major heart diseases such as ischemia and hypertrophic myocardiopathy are accompanied with significant changes in the passive mechanical properties and active contractility of myocardium. Identification of these changes helps diagnose heart diseases,
