Many applications in teleoperation and virtual reality call for the implementation of e ective means of displaying to the human operator information on the softness and other mechanical properties of objects being touched. The ability of humans to detect softness of di erent objects by tactual exploration is intimately related to both kinesthetic and cutaneous perception, and haptic displays sh...

This study was undertaken to examine how the softness of poly(ethylene) glycol (PEG)-based hydrogels, creating a three-dimensional (3D) microenvironment, influences the in vitro growth of mouse ovarian follicles. Early secondary, preantral follicles of 2 week-old mice were cultured in a crosslinked four-arm PEG hydrogel. The hydrogel swelling ratio, which relates to softness, was modified withi...

We introduce a new measure of the structure liquid which is softness mean-field potential developed by us earlier. find that this sensitive to small changes in structure. then study its correlation with supercooled dynamics. The involves wide range liquids (fragile, strong, attractive, repulsive, and active) predicts some universal behaviours like linearly proportional temperature inversely act...

A simple model to predict the directionality of vibrational energy flow at molecular level is presented. This model is based on a vibrational energy propagation analysis using ab intio molecular dynamics and the Fukui function and local softness reactivity indexes derived from DFT. By using this simple conceptual model we are giving a cogent rationale to previous theoretical and experimental re...

The paper is focused on the friendliness analysis and perception of dialogue speech. To do that, the paper uses a concept of the “perception vector” which contains the information of emotions and softness. In creating the “perception vector”, and to simulate the perception ambiguity, the paper allows the listeners to label the speech with multiple emotions, and align them into “one choice”, “fi...

Adaptive responses greatly improve the competitive capacities of bacteria in diverse environments. Here, we investigate whether bacteria can adapt to a microenvironment with distinctive softness by examining the type-IV pili (TFP)-mediated motility of Pseudomonas aeruginosa cells on brush-like surfaces that are grafted with a layer of thermally sensitive polymer chains, where the softness of th...
