Glioblastoma multiforme (GBM), a malignant brain tumor, frequently exploit microvessels as guides for migration. Understanding cell-cell interaction between vascular cells and GBM cells may suggest a new therapeutic direction. We developed physiological 3-D glioma-vascular niche model to investigate this cell-cell interaction using 3-D bioprinting technology. In the model, patient-derived GBM cell...
Due to diffusion limitation, tissues thicker than several hundred micrometers have difficulties in survival and proliferation. 3D bio-printing technology enables to create fluidic channels within tissue structures for appropriate media perfusion. This solution supports viability for the simple tissue model with limited number of cells and scaffold types; however, an additional capillary network is...
This paper is concerned with extracting 3D models from volumetric images. Building models of 3D shape relies on placement of landmarks and in many biological and medical applications automatic landmark placement is impractical. We introduce a system, called uFeel, which allows manual placement of landmarks in 3D using a combination of stereo and haptics. This system is used to capture and analyse...
In this paper, we describe the development of a distributed power flow and the economic operation for a power distribution system undergoing conversion to a strategic business unit (SBU) operation for the division of the power distribution business sectors in South Korea. The SBU is a self-regulated entity with independent responsibility for operating a local system within its budget. The financial...
