Sentence examples for persistent diffusion from inspiring English sources

The analysis of the sensibility of the model to changes in parameter values highlights that the model complies with observed ILI incidence only if an initial (persistent) diffusion of the altered behavior in the population is considered (see Text S1).

One disadvantage evident from the numerical simulations is that the maximum signal in open-well configurations is strongly dependent on the rates of secretion, as a result of persistent diffusion of material out of the wells.

Therefore, we examined the time- and dose-dependency of the improvements in arterial oxygen tension (PaO2) due to PLV in eight pigs with experimental lung injury, in order to discriminate increases due to oxygen dissolved in perfluorocarbon before its intrapulmonary instillation from a persistent diffusion of the respiratory gas through the liquid column.

Repeat examination performed using T2W FSE (d) reveals a T2 hypointense nodule in the same location (black arrow in d) with persistent restricted diffusion (white arrows in e and f) (2) Visual/quantitative analysis of DWI for tumour detection/grading is complex  .

Open image in new window Fig. 11 Example of DWI in active inflammation: a axial T1 fat-saturated post-contrast image shows thickened enhancing ileum with typical stratified enhancement pattern (arrow); b corresponding DWI (b = 800) and c ADC map confirm restricted diffusion with persistent high signal (arrow) on the DWI and low signal (arrow) on the ADC map (ROI = 1,200).

Concha et al. found persistent bilateral white matter diffusion changes postoperatively and proposed that these were probably secondary to irreversible structural damage such as myelin degradation and axonal degeneration.

Whilst the conventional picture of pore-scale mechanical dispersion and molecular diffusion leading to persistent hydrodynamic dispersion is well accepted, this paradigm is inherently two-dimensional (2D) in nature and neglects important three-dimensional (3D) phenomena.

The dMRI methods tested include constrained spherical deconvolution (CSD), Q-ball imaging (QBI), diffusion orientation transform (DOT), persistent angular structure (PAS), and neurite orientation dispersion and density imaging (NODDI) methods.

Due to the unusual appearances, she had another brain MRI in September 2011, which showed persistent signal change without enhancement, any restricted diffusion or any noticeable increase in size.

The endemic diffusion of BVDV persists in geographic areas where no systematic control measures have been implemented and it reflects the pathogenic mechanisms of BVDV through which the virus can establish both transient and persistent infections.

However, one persistent problem needs to be solved: inter-diffusion of chemical elements contained in the metal substrates and in the anodes of SOFC leads to degradation, which is to be prevented by protective coatings.
