Highly conductive and robust epidermal dry electrode for long‐term interval biopotential monitoring

FlexMat, EarlyView.
A freestanding PVA‐PBFDO conductive dry electrode combines high conductivity, flexibility, and environmental stability to enable long‐term, high‐fidelity electrophysiological (EP) signal monitoring. Its patterning capability further facilitates the fabrication of wearable and multi‐channel bioelectronic devices.

Spatiotemporal engineering of dynamic color in alternating‐current‐driven light‐emitting devices

FlexMat, EarlyView.
This review presents a mechanism‐driven framework for spectral tuning in alternating‐current‐driven light‐emitting devices, systematically integrating emissive center engineering, device architecture design, and driving signal modulation. By linking microscopic carrier dynamics and electric‐field‐charge interactions with macroscopic spectral evolution,

Structural, physicochemical, and techno‐functional properties of ultrasound‐treated chickpea starch

Food Biomacromolecules, EarlyView.
Abstract This study investigated the effects of ultrasonication duration (10, 20, 30, and 40 min) on the physicochemical, functional, structural, thermal, and rheological properties of chickpea starch. Ultrasonication significantly enhanced water absorption capacity (WAC) and oil absorption capacity (OAC), with maximum values observed for U40 (2.13 g/g

Predictive factors of discordance between the instantaneous wave‐free ratio and fractional flow reserve

Catheterization and Cardiovascular Interventions, 2019
AbstractObjectivesTo identify clinical, angiographic and hemodynamic predictors of discordance between instantaneous wave‐free ratio (iFR) and fractional flow reserve (FFR).BackgroundThe iFR was found to be non‐inferior to the gold‐standard FFR for guiding coronary revascularization, although it is discordant with FFR in 20% of cases.

Instantaneous Wave-Free Ratio Assessment

, 2016
Instantaneous wave free ratio (iFR) may be a viable alternative to FFR. iFR is a novel measurement of the hemodynamic relevance of coronary lesions which doesn’t require the use of hyperemic agents.

Numerical Simulation of Instantaneous Wave-Free Ratio of Stenosed Coronary Artery

International Journal of Computational Methods, 2019
Instantaneous wave-free ratio (iFR), an invasive index of coronary artery tree, can evaluate the functional performance of vascular stenosis without pharmacological vasodilators. The noninvasive assessment of diameter stenosis (DS) obtained from coronary computed tomography angiography (CTA) has high false positive rate in contrast to iFR.

Functional coronary assessment: instantaneous wave-free ratio and other indices

, 2018
Abstract The instantaneous wave-free ratio (iFR) is a hyperaemia-independent coronary pressure index for the physiological assessment of coronary stenoses. The underlying concept of iFR is that it quantifies the trans-stenotic pressure ratio during the wave-free period of diastole, where myocardial resistance is naturally most stable.

Comparison of Instantaneous Wave-Free Ratio (iFR) and Fractional Flow Reserve (FFR) — First Real World Experience

International Journal of Cardiology, 2015
Background: The instantaneous wave-free ratio (iFR) is a new adenosine-independent index of coronary stenosis severity. Most published data have been based on off-line analyses of pressure recordings in a core laboratory.

Minerva cardioangiologica, 2016
In the recent years it has become apparent that angiography-based assessment of coronary artery stenosis suffers from considerable inaccuracy and pitfalls. Besides interobserver variability in assessing stenosis severity, the correlation between angiographic severity and ischemia is suboptimal.
