This paper presents results of an experimental investigation of solute transport in a simplified model of the spinal canal. The work aims to provide increased understanding of the mechanisms responsible for drug dispersion in intrathecal dr...
Evaluating the accuracy of one-dimensional glottal flow model in predicting voice production: comparison to experiments and three-dimensional flow simulations [0.03%]
一维声门流模型预测发声准确度的评估:与实验及三维流体仿真对比研究

The glottal flow is often simplified as one-dimensional (1D) in phonation models to reduce computational cost. Although previous studies showed that a 1D flow model can predict voice production by a three-dimensional (3D) flow combined with...
Semi-analytical solutions of passive scalar transport in generalized Newtonian fluid flow [0.03%]

Transport during flow of generalized Newtonian fluids (GNFs) appears often in systems that can be treated in a simplified form as either cylindrical tubes or slit openings between parallel plates. Based on the pioneering work of Taylor, ana...
Time-dependent diffusion in one-dimensional disordered media decorated by permeable membranes: Theoretical findings backed by simulations and a new disorder class [0.03%]
一维穿膜无序介质中时间依赖扩散的理论研究:模拟结果支持及一个新的无序类别

As the diffusion of fluids is hindered by semipermeable membranes, the long-time behavior of the diffusion coefficient is influenced by the arrangement of the membranes. We develop methods that predict this long-time instantaneous diffusivi...
Hemodynamic simulation and in vitro modeling of three-dimensional glomeruli at anatomical scale [0.03%]

Riley Vickers et al.
Molecular-scale simulations of pressure-driven transport through polyamide nanogaps (5-100 Å) were performed to investigate fundamental transport mechanisms. Results show that transport in nanogaps ≤ 10 Å is always subdiffusive, but...
