Impairments in cell migration processes may cause various diseases, among which cancer cell metastasis, tumor angiogenesis, and the disability of immune cells to infiltrate into tumors are prominent ones. Mathematical modeling has been widely used to analyze the cell migration process. Cell migration is a complicated process and requires statistical methods such as random walk for proper analys...

Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature and the viscosity of the polymer to enhance the flexibility and processability of polymer materials. The main problem with these additives is that, over time, they migrate from the polymeric matrix and exude to the surface of p...

Neuroblasts born in the adult subventricular zone (SVZ) migrate long distances in the rostral migratory stream (RMS) to the olfactory bulbs where they integrate into circuitry as functional interneurons. As very little was known about the dynamic parameters of SVZ neuroblast migration, we used two-photon time-lapse microscopy to analyze migration in acute slices. This involved analyzing 3D stac...

Technology advances, such as WAZ/FAZ acquisition, reverse time migration (RTM) and iterative salt imaging in model building, have greatly improved subsalt image quality. However subsalt imaging under complex salt overburden is still challenging. The fundamental issue lies with the imperfect illumination from limited acquisition. In the poor illumination zones, the migration artifacts and cohere...

This paper brings a new perspective to the population growth implications of low fertility levels European countries. For years between 2009 and 2018, whether constant fertility, mortality, net migration would generate long-run or decrease is indicated simply visually by comparison total rate (TFR) migration-adjusted replacement level. The results show that, when considered in combination with ...
