Rheological Properties of Low Density Polyethylenes Produced by Tubular and Vessel Processes [PDF]
, 2001 Various rheological properties have been studied for two kinds of low-density polyethylenes (LDPEs): One is produced by tubular process (tubular LDPE) and the other by vessel process (vessel LDPE).

3D Retinal Vessel Density Mapping With OCT-Angiography
IEEE Journal of Biomedical and Health Informatics, 2020 Optical Coherence Tomography Angiography (OCTA) is a novel, non-invasive imaging modality of retinal capillaries at micron resolution. Recent studies have correlated macular OCTA vascular measures with retinal disease severity and supported their use as a diagnostic tool.

Retinal vessel segmentation using the 2-D Gabor wavelet and supervised classification
, 2006 —We present a method for automated segmentation of the vasculature in retinal images. The method produces segmentations by classifying each image pixel as vessel or nonvessel, based on the pixel’s feature vector. Feature vectors are composed of the pixel’

Higher Vessel Densities in Retinoblastoma with Local Invasive Growth and Metastasis [PDF]
The American Journal of Pathology, 2004 In this study, the importance of angiogenesis (the growth of new blood vessels from existing ones) for the growth of retinoblastoma was investigated by a retrospective immunohistochemical analysis. An individual vessel index for each tumor was determined using the endothelial-specific antibody CD 31 for vessel staining.
