Non-Maxwellian velocity distribution and anomalous diffusion of {\it in vitro} kidney cells

چکیده
This manuscript uses a statistical mechanical approach to study the effect of the adhesion, through MOCA protein, on cell locomotion. The MOCA protein regulates cell-cell adhesion, and we explore its potential role in the cell movement. We present a series of statistical descriptions of the motion in order to characterize the cell movement, and found that MOCA affects the statistical scenario of cell locomotion. In particular, we observe that MOCA enhances the tendency of joint motion, inhibits super-diffusion, and decreases overall cell motion. These facts are compatible with the hypothesis that the cells move faster in a less cohesive environment. Furthermore, we observe that velocity distribution tails are longer than those predicted by Maxwell-Boltzmann in all cases studied here, indicating that cell movement is more complex than that of a liquid.

Numerical Modeling of Non-equilibrium Plasma Discharge of Hydrogenated Silicon Nitride (SiH4/NH3/H2)
In this work, we model a radiofrequency discharge of hydrogenated silicon nitride in a capacitive coupled plasma reactor using Maxwellian and non-Maxwellian electron energy distribution function. The purpose is to investigate whether there is a real advantage and a significant contribution using non-Maxwellian electron energy distribution function rather than Maxwellian one for determining the ...
متن کاملAnomalous diffusion and q-Weibull velocity distributions in epithelial cell migration
In multicellular organisms, cell motility is central in all morphogenetic processes, tissue maintenance, wound healing and immune surveillance. Hence, the control of cell motion is a major demand in the creation of artificial tissues and organs. Here, cell migration assays on plastic 2D surfaces involving normal (MDCK) and tumoral (B16F10) epithelial cell lines were performed varying the initia...
متن کاملFull wave simulations of lower hybrid waves in toroidal geometry with Non-Maxwelian electrons
Analysis of the propagation of waves in the lower hybrid range of frequencies in the past has been done using ray tracing and the WKB approximation. Advances in algorithms and the availability of massively parallel computer architectures has permitted the solving of the Maxwell-Vlasov system for wave propagation directly [Wright et al., Phys. Plasmas (2004), 11, 2473-2479]. These simulations ha...
متن کاملNon-maxwellian Velocity Distribution Functions Associated with Steep Temperature Gradients
Non-Maxwellian electron velocity distribution functions, computed for Dupree's 1972 model of the solar transition region in a previous paper, are used to calculate ionization rates for ions of carbon, nitrogen, and oxygen. Ionization equilibrium populations for these ions are then computed and compared with similar calculations assuming Maxwellian distribution functions for the electrons. The r...
متن کاملIon Cyclotron Diffusion of Velocity Distributions in the Extended Solar Corona
The Ultraviolet Coronagraph Spectrometer (UVCS) aboard the Solar and Heliospheric Observatory (SOHO) has revealed strong kinetic anisotropies and extremely large perpendicular temperatures of heavy ions in the extended solar corona. These observations have revived interest in the idea that the high-speed solar wind is heated and accelerated by the dissipation of ion cyclotron resonant Alfvén wa...
