Dirckx JJ, Decraemer WF, Dielis G.
PMID: 20531531
Appl Opt. 1988 Mar 15;27(6):1164-9. doi: 10.1364/AO.27.001164.

A new method fur full field automatic 3-D surface reconstruction is proposed which makes use of multiple contourograms shifted in phase by object translation. The method is demonstrated for shadow moire topography. It is shown that surface reconstruction can...

Design considerations in projection phase-shift moiré topography based on theoretical analysis of fringe formation.

Journal of the Optical Society of America. A, Optics, image science, and vision

Buytaert JA, Dirckx JJ.
PMID: 17728824
J Opt Soc Am A Opt Image Sci Vis. 2007 Jul;24(7):2003-13. doi: 10.1364/josaa.24.002003.

Moiré topography is a well-established optical technique to measure the shape of three-dimensional surfaces, based on the geometric interference between an optical grid and its image deformed by an object surface. The technique produces fringes that represent contours of...

SCN5A gene mutations can lead to ion channel defects which can cause cardiac conduction disturbances. In the presence of specific ECG characteristics, this mutation is called Brugada syndrome. Many drugs are associated with adverse events, making anesthesia in patients...

Measurement and structure of spiral wave response functions.

Chaos (Woodbury, N.Y.)

Chaos. 2017 Sep;27(9):093912. doi: 10.1063/1.4999606.

The rotating spiral waves that emerge in diverse natural and man-made systems typically exhibit a particle-like behaviour since their adjoint critical eigenmodes (response functions) are often seen to be localised around the spiral core. We present a simple method...

BACKGROUND: Heart failure disproportionately affects Black patients. Whether differences among race influence outcomes in advanced heart failure with use of a fully magnetically levitated continuous-flow left ventricular assist device remains uncertain.METHODS: We included 515 IDE (Investigational Device Exemption) clinical...

Scroll wave with negative filament tension in a model of the left ventricle of the human heart and its overdrive pacing.

Physical review. E

Phys Rev E. 2021 Sep;104(3):034408. doi: 10.1103/PhysRevE.104.034408.

Nonlinear waves of electrical excitation initiate cardiac contraction. Abnormal wave propagation in the heart, e.g., spiral waves, can lead to sudden cardiac arrest. This study analyzed the dynamics of spiral waves under the influence of an instability called negative...
