Multi-view dynamic three-dimensional reconstruction has typically required the use of custom shutter-synchronized camera rigs in order to capture scenes containing rapid movements or complex topology changes. In this paper, we demonstrate that multiple unsynchronized low-cost RGB-D cameras can be used for the same purpose. To alleviate issues caused by unsynchronized shutters, we propose a novel depth frame interpolation technique that allows synchronized data capture from highly dynamic 3 D scenes. To manage the resulting huge number of input depth images, we also introduce an efficient moving least squares-based volumetric reconstruction method that generates triangle meshes of the scene. Our approach does not store the reconstruction volume in memory,making it memory-efficient and scalable to large *** implementation is completely GPU based and works in real time. The results shown herein, obtained with real data, demonstrate the effectiveness of our proposed method and its advantages compared to stateof-the-art approaches.

Dedifferentiation of cell identity to a progenitor-like or stem cell-like state with increased cellular plasticity is frequently observed in cancer *** this process,a subpopulation of cells in tumours acquires a stem cell-like state partially resembling to naturally occurring pluripotent stem cells that are temporarily present during early *** characteristics allow these cancer stem cells(CSCs)to give rise to the whole tumour with its entire cellular heterogeneity and thereby support metastases formation while being resistant to current cancer *** development and progression are demarcated by transcriptional *** this article,we explore the epigenetic mechanisms shaping gene expression during tumorigenesis and cancer stem cell formation,with an emphasis on 3D chromatin *** the pluripotent stem cell state and epigenetic reprogramming to dedifferentiation in cellular transformation provides intriguing insight to chromatin *** suggest that the 3D chromatin architecture could be used as a target for re-sensitizing cancer stem cells to therapeutics.
