MULTIPLE SCLEROSIS MSJ JOURNAL The title statement contains two separate claims: 1. 'MS is a grey matter disease', and 2. '[the grey matter part of] MS cannot be adequately assessed by standard clinical and MRI measures'. The first claim might be understood in more than one sense. For example, 'MS is a grey matter disease' might simply mean 'MS pathology is found in areas that are anatomically ...
Surface appearance (brightness and color) of an object in the scene depends on the properties of the surfaces surrounding the object (spatial induction). Size of the surrounding is one of the important influential properties. For example, a larger surrounding induces stronger contrast to the object than a smaller surrounding. Then would size-scaling of the scene alter the appearance? This quest...
This paper proposes a grey-PID type fuzzy controller (GPIDFC) with an adaptive step size to control the velocity of a spherical rolling robot characterized by a highly nonlinear system model. The proposed control structure consists of a grey predictor and a PID type fuzzy controller (PIDFC). Another fuzzy controller is proposed to tune the step size of the grey predictor. The simulation results...
We generalize here the use of the 1D Boolean model for the analysis of grey level textures. Each grey image is first split into eight binary images using different criteria. Each of these binary images is separately analysed with the help of the 1D Boolean model and features are extracted from it. The final grey texture recognition is performed on the basis of these features using several class...
MicroRNA expression profiles of patients with multiple sclerosis (MS) have revealed differences from healthy controls both in cells from the peripheral circulation and in specimens from white matter lesions. Here, we studied differences in microRNA expression and in their predicted mRNA targets in white and grey matter lesions of patients with MS as compared with white and grey matter brain tis...
