Edge states lying at the edge of PPT entangled states have a very intriguing existence and their detection is equally interesting. We present here a new witness for detection of edge states. We then compare between our proposed witness operator and the witness operator proposed in [Physical Review A, 62, 052310 (2000)] in terms of the efficiency in the detection of PPT entangled states. In this...

The “Big Bubble” (BB) technique described by Mohamed Anwar is the most popular Descemet’s baring technique wor...

Cardiac myxoma is most common among primary cardiac tumors, and its origin and tumor characteristics have been gradually elucidated by recent advances in molecular biology. Prichard's structure in the interatrial septum which was reported to be a candidate for the origin of cardiac myxoma, was revealed to be age-related changes. In hereditary cardiac myxoma "Carney complex", chromosomal abnorma...
