This paper pre sents and discusses a new approach to collect, organize and explore multiple digital videos on a spatial basis. We present a methodology based on direct video frame indexation to the real space represented in the video images. This approach facilitates the exploration of space through multiple videos. An illustrative application of this technology for multimedia spatial informati...

PURPOSE  Although papillary thyroid carcinoma metastases to the parapharyngeal space are rare, the high amount of fat tissue allows tumors to grow clinically undetectable until they invade most of the parapharyngeal space. We describe for the first time a combined endonasal and transcervical approach for a parapharyngeal metastasis from a papillary thyroid carcinoma. MATERIALS AND METHODS  A ...

in order to study the periplasmic expression of human growth hormone (hgh) in escherichia coli, the related cdna was inserted in two expression plasmids carrying pelb signal peptide, one with lac bacterial promoter and the other with a bacteriophage t7-based promoter. the recombinant plasmids were moved to tg1 and bl21 strains of e. coli, respectively. to induce the expression systems, iptg and...

Two solutions that occupy (almost) the same space in the objective space may have pre-images in the decision space that are essentially different. For a decision maker it can be interesting to know both pre-images in such cases. However, most Pareto optimization algorithms focus on diversity in the objective space only and thus will likely obtain only one solution. In this paper we propose a me...

The data cube is frequently adopted to implement On-Line Analytical Processing (OLAP) and provides aggregate information to support the analysis of contents of databases and data warehouses. Range-sum queries require accessing large data cubes and adding the contents of massive cells immediately. Techniques have thus been proposed to accelerate range-sum queries by applying pre-aggregated speci...
