We present a new user interface for the virtual sculpting system. In our system, the user operates a chisel with a pressure sensitive pen to carve a workpiece in the virtual space. The user can control the depth of carving and the angle of the virtual chisel to the surface of the workpiece dynamically like the real wood carving.
BACKGROUND Patched 1 (Ptc1) is a polytopic receptor protein that is essential for growth and differentiation. Its extracellular domains accept its ligand, Sonic Hedgehog, while the function of its C-terminal intracellular domain is largely obscure. PRINCIPAL FINDINGS In this study, we stably expressed human Ptc1 protein in HeLa cells and found that it is… (More)
Despite the enormous public health impact of Alzheimer's disease (AD), no disease-modifying treatment has yet been proven to be efficacious in humans. A rate-limiting step in the discovery of potential therapies for humans is the absence of efficient non-invasive methods of evaluating drugs in animal models of disease. Magnetic resonance spectroscopy (MRS)… (More)
In this paper, we present an interactive CG creating system with a pressure sensitive pen and a tablet. This system is based on the virtual sculpting and printing method which are simulations of the real sculpting and woodblock printing. In the virtual sculpting process, the user operates virtual chisels with the pen to sculpt a virtual wooden object which… (More)
Here, we proposed a simple recovery process for poly(3-hydroxybutyrate) (PHB) accumulated in cyanobacteria by using ionic liquids (ILs), which dissolve cyanobacteria but not PHB. First, we investigated the effects of IL polarity on hydrogen-bonding receipt ability (β value) and hydrogen-bonding donating ability (α value) and evaluated the subsequent… (More)
