Pancreatic cancer is one of the deadliest cancers, with less than 9% survival rates. Pancreatic Ductal Adeno Carcinoma (PDAC) is common with the general public affecting most people older than 45. Early detection of PDAC is often challenging because cancer symptoms will progress only at later stages (advanced stage). One of the earlier symptoms of PDAC is Jaundice. Patients with diabetes, obesity, and alcohol consumption are also at higher risk of having pancreatic cancer. A decision support system is developed to detect pancreatic cancer at an earlier stage to address this challenge. Features such as Mean Hue, Mean Saturation, Mean Value, and Mean Standard Deviation are computed after color space conversion from RGB to HSV. Fuzzy k-Nearest Neighbor (F-kNN) is designed for classification. The system proposed is trained and tested using features extracted from jaundiced eye images. The proposed system results indicate that this model can predict pancreatic cancer as earlier as possible, helping clinicians make better decisions for surgical planning. 相似文献

The electrorheological properties of colloidal dispersions of aluminum oxide nanotubes and nanoparticles in silicone oil were investigated. The shear storage modulus of colloidal dispersions containing 5 wt% of aluminum oxide nanotubes increased by four orders of magnitude upon the application of an external electric field of as low as 400 V/mm. The storage modulus of the nanotube systems increased further by increasing the concentration of nanotubes. The electrorheological response of aluminum oxide nanoparticles dispersions was significantly lower than that of the dispersions containing the same weight fraction of aluminum oxide nanotubes at the same external electric field. This result reflects the effect of shape anisotropy on the electrorheological features of colloidal dispersions. 相似文献

We report on two children who developed a fixed rotatory subluxation of the atlantoaxial joint due to torticollis being attributed to a fractured clavicle. Appropriate treatment was delayed for weeks to months; only after the fractured clavicle had healed and the torticollis persisted was the problem identified. Persisting rotatory subluxation also predisposes to further anterior displacement of C-1 due to an increased moment arm created by the forward displacement of the center of gravity of the head. The association of atlantoaxial subluxation should always be considered in children presenting with a clavicular fracture and an acute torticollis. 相似文献

A nickel incorporated carbon nanotube/nanofiber composite (Ni-CNT-CNF) was used as a low cost alternative to Pt as counter electrode (CE) for dye-sensitized solar cells (DSCs). Measurements based on energy dispersive X-rays spectroscopy (EDX) showed that the majority of the composite CE was carbon at 88.49 wt%, while the amount of Ni nanoparticles was about 11.51 wt%. Measurements based on electrochemical impedance spectroscopy (EIS) showed that the charge transfer resistance (R(ct)) of the Ni-CNT-CNF composite electrode was 0.71 Ω cm(2), much lower than that of the Pt electrode (1.81 Ω cm(2)). Such a low value of R(ct) indicated that the Ni-CNT-CNF composite carried a higher catalytic activity than the traditional Pt CE. By mixing with CNTs and Ni nanoparticles, series resistance (R(s)) of the Ni-CNT-CNF electrode was measured as 5.96 Ω cm(2), which was close to the R(s) of 5.77 Ω cm(2) of the Pt electrode, despite the significant difference in their thicknesses: ~22 μm for Ni-CNT-CNF composite, while ~40 nm for Pt film. This indicated that use of a thick layer (tens of microns) of Ni-CNT-CNF counter electrode does not add a significant amount of resistance to the total series resistance (R(s-tot)) in DSCs. The DSCs based on the Ni-CNT-CNF composite CEs yielded an efficiency of 7.96% with a short circuit current density (J(sc)) of 15.83 mA cm(-2), open circuit voltage (V(oc)) of 0.80 V, and fill factor (FF) of 0.63, which was comparable to the device based on Pt, that exhibited an efficiency of 8.32% with J(sc) of 15.01 mA cm(-2), V(oc) of 0.83, and FF of 0.67. 相似文献

Volume optimization was performed to obtain the theoretical lattice constants by using the generalized gradient approximation (GGA). The electronic and magnetic properties of Heusler alloys Co2CrZ (Z = Ga, Ge, As) were investigated by using local spin density approximation (LSDA). Amongst the systems under investigation, Co2CrGe and Co2CrGa give 100% spin polarization at the Fermi level (EF). Co2CrGe and Co2CrGa are the most stable half-metallic ferromagnets (HMFs); their EF lie exactly at the gap of 0.24 eV and 0.38 eV, respectively, in the spin-down channel. Even though Co2CrAs gives a distinct and bigger gap as compared to Co2CrGa and Co2CrGe, its EF is not located at the middle of the gap in the spin-down channel. We have also found that the total magnetic moments increase as the Z goes from Ga to As. The calculated density of states and band structures show the HMF character for Co2CrGe and Co2CrGa. 相似文献
