For transmitting olfactory information together with audio/visual information in the field of multimedia, it is necessary to control the scent presentation in accordance with the changing images and sounds presented to receivers. However, continuous emission of scents creates problems of lingering scent in air and human olfactory adaptation. To overcome such problems we applied repeated pulse ejections...
In order for robots to be able to assist humans at a very close distance, robots should allow contacts occurred at many places and deal with them. For realizing such functions, robots should have whole-body soft sensor exterior for preparing contacts against almost every body parts since it is difficult to limit where to be touched from humans. Although several groups have developed humanoid type...
In some important robotic human daily life support applications, such as housework or nursing care, soft sensor exterior is needed for allowing close contacts against humans or environments. Although there are many studies on tactile sensing elements themselves and some of them realize the mechanical softness of the element, most of their studies just propose their detection theory with their sensor...
Trials on the transmission of olfactory information together with audio/visual information are currently being conducted in the field of multimedia. However, continuous emission of a scent creates problems of human adaptation to the lingering olfactory stimuli. During long movie scenes, viewers can not detect an emitted scent continuously. To overcome this problem we applied pulse ejection to repeatedly...
One-dimensional numerical simulation is carried out in order to obtain growth rates at several temperature gradients. The simulation agrees well with experimentally obtained concentration profiles in solid. From numerical results, it is found that a growth rate is almost proportional to the temperature gradient in a low temperature-gradient region as the one-dimensional traveling liquidus-zone (TLZ)...
We established the clonal mesenchymal cell line, GFP-C3 (C3), which differentiates into osteoblasts in response to BMP-2 from calvariae of newborn green fluorescence protein (GFP) transgenic mice. This cell line cultured with control medium expressed low levels of alkaline phosphatase (ALP) activity and osterix mRNA and undetectable ALP and osteocalcin mRNA. Incubation of these cells with rhBMP-2...
We investigated the osteogenic potential of skin fibroblasts that overexpressed BMP-2 or Runx2 by using adenoviral vectors. In in vitro experiments, skin fibroblasts infected with adenovirus vector encoding BMP-2 (AdBMP-2) released substantial levels of BMP-2 proteins into culture media, and those infected with adenovirus vector encoding Runx2 (AdRunx2) produced its protein. Transduction of BMP-2...
