Purpose The purpose of this paper is to investigate a novel generalised grey target decision method (GGTDM) with index and weight involving mixed attribute values. Design/methodology/approach The mixed attribute values are transformed into binary connection numbers and also comprised of...

Different sleep stages are associated with distinct dynamical patterns in EEG signals. In this article, we explored the relationship between the sleep architecture and fractal dimension (FD) of sleep EEG. In particular, we applied the FD analysis to the sleep EEG of patients with obstructive...

Adsorption of 4He and para-H2 is predicted to exhibit exotic properties on weak-binding surfaces. For 4He, alternative scenarios include nonwetting, prewetting and a Bose gas monolayer. For H2, a monolayer superfluid phase can be created by a suitable choice of the substrate. Intriguing...
