Is a 2-dimensional (2D) force feedback device capable of presenting 3-dimensional (3D) shapes? The answer is a qualified "yes." "Force shading", a haptic counterpart of bump mapping in computer graphics, presents a non-flat shape on a nominally flat surface by varying the force vector direction in haptic rendering [Morgenbesser and Srinivasan(More)
The aim of this study was to examine the association between the-149C>T polymorphism of DNA methyltransferase 3B (DNMT3B) and colorectal cancer (CRC) susceptibility. A comprehensive search was conducted to identify all case-control studies of the-149C>T polymor-phism of DNMT3B and CRC risk. Statistical analysis was performed with the software program Stata(More)
