We have developed stacked nanocarbon polymer actuators that are composed of several nanocarbon polymer actuator films using nonwoven fabric as insulation *** nonwoven fabric prepared through electrospinning methods has extremely-low-density structures,which do not significantly prevent the motions of each nanocarbon actuator ***,stacking several thin nanocarbon polymer actuators using nonwoven fabric as insulation layers is expected to increase generated force without decreasing the displacement of a one-layer *** have prepared stacked actuators with one,two,three,four,and seven layers using this *** displacement and blocking force of these actuators are measured and compared with those of one-layer actuators of different *** is weakly dependent on the thickness of the actuator films of the stacked *** the contrary,it decreases considerably as the thickness of the actuator film of the one-layer actuator *** both cases,blocking force is proportional to the thickness of actuator *** have developed a stacked actuator model based on a trilayer actuator model and confirmed the experimental results using the model.

Utility of linked color imaging for endoscopic diagnosis of early gastric cancer

BACKGROUND Linked color imaging(LCI) is a method of endoscopic imaging that emphasizes slight differences in red mucosal *** To evaluate LCI in diagnostic endoscopy of early gastric cancer and to compare LCI and pathological *** Endoscopic images were obtained for 39 patients(43 lesions) with early gastric cancer. Three endoscopists evaluated lesion recognition with white light imaging(WLI) and LCI. Color values in Commission Internationale de l'Eclairage(CIE)1976 L*a*b* color space were used to calculate the color difference(ΔE) between cancer lesions and non-cancer areas. After endoscopic submucosal dissection,blood vessel density in the surface layer of the gastric epithelium was evaluated pathologically. The identical region of interest was selected for analyses of endoscopic images(WLI and LCI) and pathological *** LCI was superior for lesion recognition(P < 0.0001), and ΔE between cancer and non-cancer areas was significantly greater with LCI than WLI(29.4 vs 18.6, P <0.0001). Blood vessel density was significantly higher in cancer lesions(5.96% vs4.15%, P = 0.0004). An a* cut-off of ≥ 24 in CIE 1976 L*a*b* color space identified a cancer lesion using LCI with sensitivity of 76.7%, specificity of 93.0%, and accuracy of 84.9%.CONCLUSION LCI is more effective for recognition of early gastric cancer compared to WLI as a result of improved visualization of changes in redness. Surface blood vessel density was significantly higher in cancer lesions, and this result is consistent with LCI image analysis.
