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...

Eight years of passive acoustic data (2007–2014) from the Beaufort Sea were used to estimate mean cue rate (calling rate) individual bowhead whales (Balaena mysticetus) during their fall migration along North Slope Alaska. Calls detected on directional recorders (DASARs) triangulated provide estimates locations at times call production, which then translated into densities (calls/h/km2). Variou...

Stable isotopes of carbon, nitrogen, and sulfur are used as ecological tracers for a variety of applications, such as studies of animal migrations, energy sources, and food web pathways. Yet uncertainty relating to the time period integrated by isotopic measurement of animal tissues can confound the interpretation of isotopic data. There have been a large number of experimental isotopic diet sh...

in exploration seismology, migration refers to a multi-channel processing step that attempts to spatially re-position events and improve focusing. before migration, seismic data is usually displayed with traces plotted at the surface location of the receivers and with a vertical time axis. this means that dipping reflections are systematically mispositioned in the lateral coordinate and the ver...

Abstract Background Migratory animals use information from the Earth’s magnetic field on their journeys. Geomagnetic navigation has been observed across many taxa, but how geomagnetic to find way is still relatively unknown. Most migration studies a static representation of and do not consider its temporal variation. However, short-term perturbations may affect respond - understand this phenome...

Two-photon microscopy has substantially advanced our understanding of cellular dynamics in the immune system. Cell migration can now be imaged in real time in the living animal. Strikingly, the migration of naive lymphocytes in secondary lymphoid tissue appears predominantly random. It is unclear, however, whether directed migration may escape detection in this random background. Using a combin...

kcnk2 was previously shown to regulate immune-cell trafficking into the central nervous system (cns). kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the cns. an upregulation of the cellular adhesion molecules icam1 and vcam1 on brain endothelial cells in k...
