Physical Variables Underlying Tactile Stickiness During Fingerpad Detachment

open access: yesFrontiers in Neuroscience, 2020
One may notice a relatively wide range of tactile sensations even when touching the same hard, flat surface in similar ways. Little is known about the reasons for this variability, so we decided to investigate how the perceptual intensity of light ...

Study on the Influence of the New Type of Powder Metallurgy Ti-Al-Nb Alloy Hot Press Sintering Process on the Microstructure [PDF]

open access: yesE3S Web of Conferences, 2021
Based on the hot-pressing sintering process, the kinetics of hot-pressing sintering crystal grain growth and the hot-pressing sintering densification kinetics, the mixing ratio of the raw material powder and the hot-pressing sintering system are designed.

Thermoelectric property studies on thallium-doped lead telluride prepared by ball milling and hot pressing [PDF]

open access: yes, 2010
Thallium doping into lead telluride has been demonstrated to increase the dimensionless thermoelectric figure-of-merit (ZT) by enhancing Seebeck coefficient due to the creation of resonant states close to Fermi level without affecting the thermal ...

Quick discrimination of A delta and C fiber mediated pain based on three verbal descriptors [PDF]

open access: yes, 2010
Background: A delta and C fibers are the major pain-conducting nerve fibers, activate only partly the same brain areas, and are differently involved in pain syndromes.

Coherent State Approach to Quantum Clocks [PDF]

open access: yes, 1997
The ``problem of time'' has been a pressing issue in quantum gravity for some time. To help understand this problem, Rovelli proposed a model of a two harmonic oscillators system where one of the oscillators can be thought of as a ``clock'' for the other

Deformation rate of engineered wood flooring with response surface methodology and adaptive network-based fuzzy inference system.

open access: yesPLoS ONE, 2023
Controlling the deformation rate is the key to improving the product quality of engineered wood flooring. In this work, the changes in the deformation rate of engineered wood flooring were in focus with cold-pressing, response surface methodology, and ...

Thermal stability of the microstructure of severely deformed copper [PDF]

open access: yes, 2006
Copper specimens were deformed by equal channel angular pressing (ECAP) up to 8 passes. The microstructure was studied by X-ray line profile analysis. The crystallite size is reduced to a few tens of nanometers even after the first ECAP pass and it does ...

The Ontology of Material Objects [PDF]

open access: yes, 2002
[First paragraph] For a long time philosophers thought material objects were unproblematic. Or nearly so. There may have been a problem about what a material object is: a substance, a bundle of tropes, a compound of substratum and universals, a ...
