A simple method is introduced for analyzing error score distributions from the Farnsworth-Munsell 100-Hue test. The method involves fitting a sine wave directly to the error distribution, and produces estimates of three parameters that characterize the severity of the defect, the degree of bipolarity, and the orientation of the axis of bipolarity, if one is present. The method produces good est...

The effect of hydrogenation on the intensity evolution of ZnO single crystal under electron beam irradiation was investigated by cathodoluminescence (CL). Without hydrogenation, the ultraviolet (UV) emission for O-face decreases exponentially and reaches a constant value with e-beam irradiation, while that for Zn-face once increases and then decreases. The hydrogenation significantly increases ...

We present the explicit expressions in N=8 supergravity for the bosonic 4-particle tree and 1-loop amplitudes including vectors and scalars. We also present the candidate 4point UV divergences in a form of helicity amplitudes, corresponding to 3-loop manifestly N=8 supersymmetric and Lorentz covariant counterterm. This may shed some light on the 3-loop finiteness of N=8 SG and on a conjectured ...

We have successfully introduced green phosphors LaPO4:Ce, Tb (G4) or (Mg, Zn)Al11O19:Eu (G2) into TiO2 photoelectrode of dye-sensitized solar cells. The conversion efficiency of the G4-doped device was enhanced by 30% compared with the pristine TiO2 photoelectrode. The green phosphor doped at 5-wt.% ratio contributed to the reduction of resistances of the surface and interface of the photoelect...

background: bromide is found naturally in groundwater and surface water. the rapid growth of industrial activities, drainage of surface runoff, and use of methyl bromide in pesticides has increased bromide discharge to the environment. disinfection of water-containing bromide causes the creation of additional products of organo-halogenated that are considered cancer-causing agents. in this stud...

background and aims: despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. blood-borne pathogen transmission has been a concern since the earliest days of transfusion. the blood product of platelet (plt) concentrates is still faced with the risk of bacterial and viral contaminations. pathogen inactivation technologies offer a proac...
