A step toward clinically applicable noninvasive coronary wave intensity analysis [PDF]

American Journal of Physiology-Heart and Circulatory Physiology, 2016
the mechanisms underlying a striking diastolic predominance of left ventricular coronary arterial blood flow have been the subject of intensive investigation for many years, starting with the first reliable measurements of phasic coronary arterial flow by Gregg and Green ([9][1]) in 1940 ...

Measuring the Interaction Between the Macro- and Micro-Vasculature

Frontiers in Cardiovascular Medicine, 2019
Structural and functional dysfunction in both the macro- and microvasculature are a feature of essential hypertension. In a healthy cardiovascular system, the elastic properties of the large arteries ensure that pulsations in pressure and flow generated ...

Heterodyne Near-Field Scattering

, 2003
We describe an optical technique based on the statistical analysis of the random intensity distribution due to the interference of the near-field scattered light with the strong transmitted beam.

Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011 [PDF]

, 2012
In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these bands, with the measurement for each of them of the ...

Charge density wave in hidden order state of URu$_2$Si$_2$

, 2010
We argue that the hidden order state in URu$_2$Si$_2$ will induce a charge density wave. The modulation vector of the charge density wave will be twice that of the hidden order state, $Q_{CDW} = 2Q_{HO}$.

Altered cardiac‐coronary coupling relates to abnormal fractional flow reserve without flow limitation after percutaneous coronary interventions

Physiological Reports
A significant proportion of stenoses have an abnormal fractional flow reserve (FFR) after angiographically successful percutaneous coronary intervention (PCI), which is traditionally attributed to differences in coronary flow velocity reserve (CFVR) or ...

Wave Power Assessment in the Middle Part of the Southern Coast of Java Island

Energies, 2020
An assessment of the wave power at the southern coast of the middle part of Java Island (Indonesia) was conducted based on a 15-year hindcast spectral wave model using the MIKE 21 Spectral Wave software.

Inelastic scattering of broadband electron wave packets driven by an intense mid-infrared laser field

, 2011
Intense, 100 fs laser pulses at 3.2 and 3.6 um are used to generate, by multi-photon ionization, broadband wave packets with up to 400 eV of kinetic energy and charge states up to Xe+6.

Wave Intensity Analysis and Central Blood Pressure [PDF]

Hypertension, 2009
In this issue of Hypertension , Manisty and colleagues1 provide, using wave intensity analysis (WIA), new insight into hemodynamic mechanisms of blood flow and energy transfer in conduit arteries which are relevant to the basic pathophysiology of cardiovascular disease.

Wave intensity analysis: A novel non-invasive method for determining arterial wave transmission [PDF]

, 2002
Wave intensity analysis is a novel technique for assessing wavelet transmission in the cardiovascular system. Using this tool, we have developed non-invasive techniques to study wave transmission in both central & peripheral arteries in man.
