Nuclear fragmentation and the number of particle tracks in tissue [PDF]
Radiation Protection Dosimetry, 2006 For high energy nuclei, the number of particle tracks per cell is modified by local nuclear reactions that occur, with large fluctuations expected for heavy ion tracks. Cells near the interaction site of a reaction will experience a much higher number of tracks than estimated by the average fluence. Two types of reaction products are possible and occur

Context specific descriptors for tracking deforming tissue [PDF]
Medical Image Analysis, 2012 In minimally invasive surgery, deployment of motion compensation, dynamic active constraints and adaptive intra-operative guidance require accurate estimation of deforming tissue in 3D. To this end, the use of vision-based techniques is advantageous in that it does not require the integration of additional hardware to the existing surgical settings ...

Tracking Bacterial Nanocellulose in Animal Tissues by Fluorescence Microscopy
Nanomaterials, 2022 The potential of nanomaterials in food technology is nowadays well-established. However, their commercial use requires a careful risk assessment, in particular concerning the fate of nanomaterials in the human body. Bacterial nanocellulose (BNC), a nanofibrillar polysaccharide, has been used as a food product for many years in Asia.
