Pulse Dynamics in a Bistable Reaction-Diffusion System with Chemotaxis

open access: yesAdvances in Mathematical Physics, 2022
We consider pulse dynamics in a bistable reaction-diffusion system with chemotaxis. We derive the ordinary differential equation of interfaces by applying the multiple scales method to the reaction-diffusion system for examining the effect of the ...

Study on the law of influence by slurry viscosity on the fractured aquifer grouting and diffusion

open access: yes矿业科学学报, 2021
This study is to investigate the influence of slurry viscosity on the diffusion and filling of slurry during grouting reinforcement. Firstly, based on the newly developed test device, the diffusion process of three kinds of viscosity slurry in the ...

Investigating effects from restricted diffusion in multi-component diffusion data [PDF]

open access: yes, 2014
We have investigated model systems in which effects from non-Gaussian restricted diffusion could be separated from effects caused by multiple diffusion coefficients. We applied various models to analyze the experimental data.

Effect of the Nitrogen Diffusion Layer Formed by Gas Blow Induction Heating Nitriding on Wear Resistance and Fatigue Properties of Titanium Alloy

open access: yesProceedings, 2018
The effect of the nitrogen diffusion layer formed by gas blow induction heating nitriding on the wear resistance and the fatigue properties of a titanium alloy was investigated.

Vortex generation in a finitely extensible nonlinear elastic Peterlin fluid initially at rest

open access: yesEngineering Reports, 2020
It is well known that the mixing of two or more species in flows at low Reynolds numbers cannot be easily achieved since inertial effects are essentially absent and molecular diffusion is slow.

Heavy-quark suppression and anisotropic flow at intermediate momentum [PDF]

open access: yesEPJ Web of Conferences
We discuss heavy quark diffusion and radiation in an intermediate-momentum regime where the heavy-quark mass is non-negligible. Based on the collision kernel for diffusion, elastic scattering and semicollinear gluon-bremsstrahlung can be consistently ...

On the nanoindentation behavior of a TiC layer formed through thermo-reactive diffusion during hot pressing of Ti and cast iron

open access: yesMaterials Letters: X, 2022
Hot pressing of pure Ti and cast iron under vacuum formed a ∼15 µm wide TiC-layer through the thermo-reactive diffusion process. Nanoindentation testing of the TiC-layer revealed average hardness and elastic modulus values of ∼35 GPa and ∼400 GPa ...

THE DENSITY FUNCTIONAL THEORY STUDY OF Li-ION DIFFUSION IN Na-DOPED Li4Ti5O12 AS LITHIUM-ION BATTERY ANODE

open access: yesSpektra: Jurnal Fisika dan Aplikasinya, 2022
Spinel phase lithium titanate (Li4Ti5O12 or LTO) has been studied as an alternative anode material with a “zero-strain” characteristic structure to improve safety, cycling stability, and rate performance.

Using Diffusion-Diffusion Exchange Spectroscopy to observe diffusion exchange in yeast [PDF]

open access: yes, 2019
The permeability of cell membranes varies significantly across both healthy and diseased tissue, and changes in cell membrane permeability can occur during treatment response in tumours.

Exploring the influence of lactoferrin on wound healing and related signaling pathways: a systematic review

open access: yesFEBS Open Bio, EarlyView.
Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.
