Role of Doppler in Predicting the Complicated and Impending to Complicate Cases of Acute Appendicitis [PDF]
International Journal of Anatomy Radiology and Surgery, 2017 Introduction: Acute appendicitis is one of the most common emergency surgical problems which could result due to obstructive or non-obstructive causes. The obstructive type progresses fast and could result in complications like gangrene formation and

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
Advanced Functional Materials, EarlyView.The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Pulsatile microvascular blood flow imaging by short-time Fourier transform analysis of ultrafast laser holographic interferometry [PDF]
, 2015 We report on wide-field imaging of pulsatile microvascular blood flow in the exposed cerebral cortex of a mouse by holographic interferometry. We recorded interferograms of laser light backscattered by the tissue, beating against an off-axis reference ...
