The phrase "an external driving force" is correct and usable in written English.
You can use it to describe an outside influence or motivation that propels action or change.
Example: "The new regulations served as an external driving force for the company to innovate its processes."
Alternatives: "an outside motivator" or "a foreign impetus".
Many proteins can switch from one conformation to another under the influence of an external driving force, such as the binding to a specific substrate.
The point is that, even such a case, the control input should be an external driving force and no the displacement.
To investigate gas transport in the same structures, we insert an external driving force into non-equilibrium molecular dynamics (NEMD) simulations and find that Knudsen diffusion is the dominant transport mechanism in the pore networks.
Assemblies with higher positive values of ΔGdiss are more thermodynamically stable, and that value indicates that an external driving force is required to dissociate the assembly.
These results lead to the conclusion that capsid assembly around genomic (overcharged) NAs requires an external driving force such as a Donnan potential (Ting et al., 2011).
One example of such an external driving force is a World Bank loan in the 1990s that required the Peruvian government to assign 10% of the loan to the development of a comprehensive road safety strategy.
This paper presents a capillary-driven microfluidic device that uses surfactant-added poly(dimethylsiloxane) (PDMS) to extract plasma from the blood without any external driving force.
The results indicate that: (1) the device is capable of dissipating 40 W of thermal energy and keeping the chip surface temperature under 100°C; (2) the device can transfer heat from the evaporator to the condenser through natural circulation (i.e., without any external driving forces) if the relative height difference between the evaporator and condenser is greater than 1 cm.
Although porosity and pore connectivity affect the natural gas diffusion in the pore networks, we typically observe a linear relationship between average molar flow rate through a cross-sectional area and the external driving force.
Temperature is uniform across most of the channel but presents an increase close to the solid walls especially when increasing the external driving force.
Lower rate of separation under the same external driving force means increased power consumption (Baker 2012).
