allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...

Face recognition based on the analysis of 3D scans has been an active research subject over the last few years. However, the impact of the resolution of 3D scans on the recognition process has not been addressed explicitly yet being of primal importance after the introduction of a new generation of low cost 4D scanning devices. These devices are capable of combined depth/rgb acquisition over ti...

Purpose: In the current study, using different radiobiological models, tumor control probability (TCP) and normal tissue complication probability (NTCP) of radiotherapy plans were calculated for three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT) of prostate cancer.Methods and Materials: 10 prostate plans were randomly selected among patients ...

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...

Internet data almost double every year. The need of multimedia communication is less storage space and fast transmission. So, the large volume of video data has become the reason for video compression. The aim of this paper is to achieve temporal compression for three-dimensional (3D) videos using motion estimation-compensation and wavelets. Instead of performing a two-dimensional (2D) motion s...

Three-dimensional (3D) stem cell differentiation cultures recently emerged as a novel model system for investigating human embryonic development and disease progression in vitro, complementing existing animal and two-dimensional (2D) cell culture models. Organoids, the 3D self-organizing structures derived from pluripotent or somatic stem cells, can recapitulate many aspects of structural organ...

Three-dimensional (3D) computational modeling of the auditory periphery forms an integral part of modern-day research in cochlear implants (CIs). These models consist of a volume conduction description of implanted stimulation electrodes and the current distribution around these, coupled with auditory nerve fiber models. Cochlear neural activation patterns can then be predicted for a given inpu...

This paper proposes a loss-less method for encoding and compressing three-dimensional (3D) geometric models that may contain any combinations of wireframe, surface, and solid forms as well as various non-simple topological structure (e.g. cavities and strut edges) that could exist in 3D CAD models. Given a model, our method transforms it into a simple triangular mesh model by applying a sequenc...
