A patent has been issued for an embedding medium that allows for the imaging of biological samples using light and/or electron microscopy. The medium, derived from a mixture of specific monomers, provides efficient imaging contrast and preserves the ultrastructure and fluorescence of the sample. It also reduces the need for contrasting agents and heavy metal salts, which can be toxic and alter biological properties. The invention aims to optimize electron microscopy in biological studies and provide a non-biointeracting medium that preserves the native fluorescence of the sample. [Extracted from the article]

Tracking ground moving targets with ground moving target indicator (GMTI) measurements only could face a potential problem of losing tracks or track mingling, if the targets move together within the range of GMTI sensing uncertainty for an extended period of time. We propose a remedy for this problem by using local motion features extracted from high resolution range (RRR) profiles to assist data association. Unlike other HRR features, the new local motion features carry both spatial and temporal information and are ideal for feature aided tracking. A probabilistic logic based tracker is developed for local motion feature aided tracking. [ABSTRACT FROM AUTHOR]
