Summary
Collective electrotaxis involves cells moving in an electric field. A new model explains velocity variations in epithelial sheets, enabling controlled collective cell migration patterns.
Area of Science:
- Cellular Biophysics
- Developmental Biology
Background:
- Collective electrotaxis describes cellular collective migration under electric fields.
- Spatial heterogeneity in migration velocity is observed in large epithelia.
Approach:
- Developed a continuum model for cue competition within migrating tissues.
- Validated a reaction-convection-diffusion model for epithelial electrotaxis.
- Investigated the impact of tissue size and geometry on MDCK monolayer migration.
Key Points:
- Cue competition explains velocity heterogeneity in collective electrotaxis.
- The reaction-convection-diffusion model accurately describes epithelial monolayer movement.
- Tissue size and geometry influence collective migration patterns.
Conclusions:
- Electric field design can control collective migration patterns.
- Bespoke stimulation protocols can be designed for specific applications.
- This work provides a framework for understanding and manipulating electrotaxis.

01:27Induced Electric Fields: Applications
1.6K
An important distinction exists between the electric field induced by a changing magnetic field and the electrostatic field produced by a fixed charge distribution. Specifically, the induced electric field is nonconservative because it does not work in moving a charge over a closed path. In contrast, the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field but not the induced field. The following...

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.

01:27Electrostatic Boundary Conditions in Dielectrics
1.2K
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the electric field. This results in electrostatic boundary conditions that depend on the type of mediums the field propagates through.
Consider a case where both the mediums across a boundary are two different dielectric materials. Recall that the electric field and electric displacement are proportional and related through the material's...

Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.

The fact that emfs are induced in circuits implies that work is being done on the conduction electrons in the wires. What can possibly be the source of this work? We know that it’s neither a battery nor a magnetic field, as a battery does not have to be present in a circuit where current is induced, and magnetic fields never do any work on moving charges. The source of the work is in fact an electric field that is induced in the wires. For example, if a stationary conductor is placed in a...

01:14Conservation of Energy in Control Volume

Consider a turbine operating under steady-flow conditions. The control volume is drawn around the turbine, with fluid entering at one point and exiting at another. The turbine extracts energy from the fluid, which performs mechanical work (shaft work).
For steady flow systems, the time derivative of the stored energy becomes zero since there is no energy accumulation within the control volume. This simplifies the energy equation to:
