Hemodynamics of thrombus formation in intracranial aneurysms: An in silico observational study
APL Bioengineering, 2023 How prevalent is spontaneous thrombosis in a population containing all sizes of intracranial aneurysms? How can we calibrate computational models of thrombosis based on published data?

Journal of the American College of Cardiology, 1987 Imaging has become a widely used technique for the evaluation of cardiac disease. Computer technology and techniques have had an enormous impact on many of the available cardiac imaging methods. These methods include echocardiography, digital angiography, radionuclide imaging, X-ray computed tomography and nuclear magnetic resonance imaging.

Computing Robustness and Persistence for Images [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2010 We are interested in 3-dimensional images given as arrays of voxels with intensity values. Extending these values to a continuous function, we study the robustness of homology classes in its level and interlevel sets, that is, the amount of perturbation needed to destroy these classes.

Applied Optics, 2017 Most LADAR (laser radar, LIDAR) imaging systems use pixel-basis sampling, where each azimuth and elevation resolution element is uniquely sampled and recorded. We demonstrate and examine alternative sampling and post-detection processing schemes where recorded measurements are made in alternative bases that are intended to reduce system power ...

Efficient generation of longitudinally polarized light needle with diffractive optical elements
Results in Optics, 2023 Longitudinally polarized beams have unique properties that are different from a traditional transversely polarized beam. By modulating the amplitude, phase and polarization of the incident beam, various longitudinal polarization fields can be obtained in

Computational metaoptics for imaging
CoRRMetasurfaces -- ultrathin structures composed of subwavelength optical elements -- have revolutionized light manipulation by enabling precise control over electromagnetic waves' amplitude, phase, polarization, and spectral properties. Concurrently, computational imaging leverages algorithms to reconstruct images from optically processed signals ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
