The differentiation of sensory neurons involves gene expression changes induced by specific transcription factors. Vomeronasal sensory neurons (VSNs) in the mouse vomeronasal organ (VNO) consist of two major subpopulations of neurons expressing vomeronasal 1 receptor (V1r)/Gαi2 or vomeronasal 2 receptor (V2r)/Gαo, which differentiate from a common neural progenitor. We previously demonstrated that...
In our research, a 3D terrain model is automatically generated from key contour polygons by straight skeleton computation. Based on key contours given elevation, the faces connecting key contours are automatically formed, and thus 3D terrain models are automatically created. The proposed system performs physical simulations, using a more realistic environment, such as an automatically generated 3D...
A 3D urban model is important in urban planning and game industries. However, creating these 3D models are labor-intensive. In order to automate laborious steps, a GIS (Geographic Information System) and CG (Computer Graphics) integrated system is proposed for automatically generating 3D building models, based on building polygons on a digital map. These polygons are usually orthogonal. A complicated...
With the goal of providing instruction with an optimum method to achieve the target given in the learning process, PID control theory was applied and an assessment was made of the proportion(P), integral(I), and differential(D) of the learner’s level of understanding. Using these parameters, a web server system was constructed as a teaching model adopting learning rules extracted from optimum problems...
