Table 1.

Molecular dynamics (MD) simulations of LPS/DPPE membranes using the NVT/NPT equilibration protocol and different barostats, thermostats, and long-range electrostatic (LRE) approximations. Pressure (τp) and temperature (τT) coupling constants in ps. Simulations were performed in duplicate.
