Abstract: A method for predicting clinical severity of a neurological disorder includes steps of: a) identifying, according to a magnetic resonance imaging (MRI) image of a brain, brain image regions each of which contains a respective portion of diffusion index values of a diffusion index, which results from image processing performed on the MRI image; b) for one of the brain image regions, calculating a characteristic parameter based on the respective portion of the diffusion index values; and c) calculating a severity score that represents the clinical severity of the neurological disorder of the brain based on the characteristic parameter of the one of the brain image regions via a prediction model associated with the neurological disorder.

Abstract: A lamp comprises a base, at least one light source arranged on the base, a cover positioned on the base and covering the light source, and a structured film arranged adjacent to the light source. The structured film has at least one micro structure configured for guiding part of the light backward emitted from the light source.

Abstract: An illumination device is provided in the present disclosure. The illumination device may include a substrate having a first surface, at least one light-aggregation component having a free-form curved surface and located on the first surface, at least one light source at least partially surrounded by the light-aggregation component, and a light-mix component positioned adjacent to the first surface and the at least one light-aggregation component thereof.

Abstract: The invention relates to a zoom lens for DLP projector. The zoom lens of the invention comprises a focus group, a zoom group and a compensation group. The zoom group comprises three zoom units with positive, negative, positive optical power respectively. The compensation group comprises a first compensation unit, a second compensation unit, an aperture stop and a third compensation unit. Corresponding to the aperture stop, the compensation lens of the compensation units have positive radius, positive radius, positive radius and negative radius respectively. The zoom lens of the invention utilizes the zoom group and the compensation group so that firstly, the F-number of the zoom lens of the invention can be fixed at 2.2; secondly, the relative luminance of the zoom lens of the invention can be up to 60% even at extreme corner; thirdly, the tolerance of the zoom lens of the invention is comparatively excellent.
