We establish the physical origins of chemical transferability from the perspective of the nearsightedness of electronic matter. To do this, we explicitly evaluate the response of electron density to a change in the system, at constant chemical potential, by computing the softness kernel, [Formula: see text] The softness kernel is nearsighted, indicating that under constant-chemical-potential co...

The hygiene tissue industry has an extensive global market that is quickly growing. Market research indicated softness one of consumers’ most highly desired properties. For certain products (specifically bath tissue), this property can influence prices. A better understanding the science would allow companies to engineer soft more economically and efficiently. Softness a subjective perception r...

A system for morphing the softness and brightness of two sounds independently from their other perceptual or acoustic attributes was coded. The system is an extension of a previous one that morphed brightness only, that was based on the Spectral Modelling Synthesis additive/residual model. A Multidimensional Scaling analysis, of listener responses to paired comparisons of stimuli generated by t...

Haptic perception involves both cutaneous perception, through mechanoreceptors lying on the skin, and kinaesthetic perception mediated by the position of the fingers. Analogously, artificial devices should replicate both these perceptual channels, as well. While kinesthetic information is satisfactorily replicated by current technology, cutaneous information is still a challenging task to be pr...
