Cells moving collectively in tissues constitute a form of active matter, in which collective motion depends strongly on driven fluctuations at the single-cell scale. Fluctuations in cell area and number density are often seen in monolayers, yet their role in collective migration is not known. Here we study density fluctuations at the single- and multicell level, finding that single-cell volumes...
New developments in Faraday rotation polarimetry have provided the first measurements of current density profile and core magnetic fluctuations in the core of a high-temperature reversed field pinch. This has been achieved by a fast-polarimeter system with time response up to 1 ms and phase resolution ,1 mrad. Recent experiments on Madison Symmetric Torus have directly measured radial magnetic ...
We use the plasma density based on measurements of probe-to-spacecraft potential in combination with magnetic field by MAG to study fields and fluctuations solar wind observed Solar Orbiter during first perihelion encounter ($\sim$0.5~AU away from Sun). In particular we polarization wave field, phase between compressible compressibility ratio (the normalized B) characterize waves turbulence. fi...
