A baseline-free damage detection approach based on distance compensation of guided waves

Journal of Low Frequency Noise, Vibration and Active Control, 2019
The baseline signal in structural inspection based on guided waves is difficult to be obtained under varying environmental conditions. To guarantee the precision of damage identification, developing baseline-free damage detection methods is significant ...

TCT-151 Instantaneous Wave-Free Ratio/Fractional Flow Reserve Discordance: Is The ‘Wave-Free Period’ Truly ‘Wave-Free'?

Journal of the American College of Cardiology, 2018
Instantaneous wave-free ratio (iFR) and Fractional Flow Reserve (FFR) are the most used physiologic indices in coronary artery disease (CAD) assessment. iFR and FFR are discordant in up to a fifth of cases.

Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Sound wave generation by a spherically symmetric outburst and AGN Feedback in Galaxy Clusters

, 2017
We consider the evolution of an outburst in a uniform medium under spherical symmetry, having in mind AGN feedback in the intra cluster medium (ICM). For a given density and pressure of the medium, the spatial structure and energy partition at a given ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Simplifying the Assessment of Coronary Artery Stenosis by Enhancing Instantaneous Wave Free Ratio [PDF]

Archives of Cardiovascular Diseases Supplements, 2017
Instantaneous wave free ratio (iFR) does not require adenosine, but has a relatively wide intermediate range where functional assessment remains inconclusive. In this pilot study, we sought to enhance iFR through with the use of intracoronary (IC) saline (iFRs) and contrast media (iFRc) and determine whether these techniques correlated well with ...
