OBJECTIVES To establish a normative database for magnetisation transfer ratio (MTR) measurements in the white matter of healthy adult brains. Such MTR values were evaluated for regional variation and evidence of differences associated with aging, sex, and handedness. METHODS Forty one healthy volunteers, ranging in age from 16 to 55 years, underwent axial brain magnetisation transfer (MT) ima...

We study twenty four written natural languages. We draw in the log scale, number of words starting with a letter vs rank of the letter, both normalised. We find that all the graphs are of the similar type. The graphs are tantalisingly closer to the curves of reduced magnetisation vs reduced temperature for magnetic materials. We make a weak conjecture that a curve of magnetisation underlies a w...

Magnetisation transfer imaging (MTI) is a magnetic resonance imaging (MRI) technique that has a higher specificity than conventional T2-weighted scans to the heterogeneous pathological substrates of multiple sclerosis (MS) lesions. This review outlines the contribution of MTI in the study of lesion evolution and in the assessment of disease burden in MS. MTI studies of individual MS lesions con...

The ultrafast (sub-nanosecond) magnetisation dynamics of ferromagnetic thin films and elements that find application in spintronic devices is reviewed. The major advances in the understanding of the magnetisation dynamics in the two decades since the discovery of giant magnetoresistance and the prediction of spin transfer torque are discussed, along with the plethora of new experimental techniq...

It is proposed to shoot a molecule through a pipe of mesoscopic scale. The molecule should effectifely carry two spins and antiferromagnetic chains should be embedded in the wall of the tube. If the momentum is detected before and behind the tube, a projection of the molecular spins ~σ1 and ~σ2 takes place. If the molecule did not loose momentum inside the tube, it has a vanishing squared total...
