Investigation of reciprocating friction characteristics between different bionic surfaces of prosthesis materials and skin

open access: yesBiosurface and Biotribology, 2019
In this study, three types of bionic texture surfaces were designed, based on the microstructure of tree frog and gecko feet, for two typical prosthetic substrates: silicone rubber and thermoplastic polyurethane elastomer (TPU). The surface energy of all

Aerobic but not thermoregulatory gains following a 10‐day moderate‐intensity training protocol are fitness level dependent: A cross‐adaptation perspective

open access: yesPhysiological Reports, 2020
Moderate‐intensity exercise sessions are incorporated into heat‐acclimation and hypoxic‐training protocols to improve performance in hot and hypoxic environments, respectively. Consequently, a training effect might contribute to aerobic performance gains,

Measuring miniature eye movements by means of a SQUID magnetometer [PDF]

open access: yes, 1982
A new technique to measure small eye movements is reported. The precise recording of human eye movements is necessary for research on visual fatigue induced by visual display units.1 So far all methods used have disadvantages: especially those which are ...

M2U-net: Effective and efficient retinal vessel segmentation for real-world applications [PDF]

open access: yes, 2020
In this paper, we present a novel neural network architecture for retinal vessel segmentation that improves over the state of the art on two benchmark datasets, is the first to run in real time on high resolution images, and its small memory and ...

Calculation of the Gibbs–Donnan factors for multi-ion solutions with non-permeating charge on both sides of a permselective membrane

open access: yesScientific Reports, 2021
Separation of two ionic solutions with a permselective membrane that is impermeable to some of the ions leads to an uneven distribution of permeating ions on the two sides of the membrane described by the Gibbs–Donnan (G–D) equilibrium with the G–D ...

Combining Household Income and Expenditure Data in Policy Simulations [PDF]

open access: yes, 2004
Analysis of the distributional impact of fiscal policy proposals often requires information on household expenditures and incomes. It is unusual to have one data source with high quality information on both, and this problem is generally overcome with ...

EtCO2-Based Biofeedback Method of Breath Regulation Increases Speech Fluency of Stuttering People

open access: yesArchives of Acoustics, 2015
Respiratory disturbances frequently accompany stuttering. Their influence on lung ventilation can be assessed by measurement of the end-tidal CO2 concentration (EtCO2).

The amblyopic eye in subjects with anisometropia show increased saccadic latency in the delayed saccade task

open access: yesFrontiers in Integrative Neuroscience, 2014
The term amblyopia is used to describe reduced visual function in one eye (or both eyes, though not so often) which cannot be fully improved by refractive correction and explained by the organic cause observed during regular eye examination.

Highly Stable Potentiometric (Bio)Sensor for Urea and Urease Activity Determination

open access: yesMembranes, 2021
There is growing interest for bioanalytical tools that might be designed for a specific user, primarily for research purposes. In this perspective, a new, highly stable potentiometric sensor based on glassy carbon/polyazulene/NH4+-selective membrane was ...
