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 magnetic cleaning assembly includes an inner and an outer magnetic cleaner member for attaching onto inner and outer peripheral surfaces of an aquarium, the inner magnetic cleaner member includes two blocks rotatably secured together with a pivot device and foldable relative to each other, two magnetic elements are attached to the blocks, and the outer magnetic cleaner member includes one or more magnetic elements to act with the magnetic elements of the inner magnetic cleaner member, and to move the inner magnetic cleaner member along the inner peripheral surface of the aquarium, the blocks of the inner magnetic cleaner member are foldable relative to each other for moving over corner areas of the aquarium.
