In langevin dynamics, equations of motions are modified to incorporate the viscosity of the solution and the effect of collisions between molecules. Allows effect of water to be modelled without modelling each atom. What are the computational advantages of using langevin dynamics over Molecular dynamics? Natural Statistical ensemble for MD simulation is NVT, but often NVE and NPT are implemented. What additional factors need to be included for these to be implemented?

Consider the aircraft model shown in Figure 1. We will assume that the aircraft is in steady-cruise at constant altitude and velocity; thus, the thrust, drag, weight and lift forces balance each other in the x- and y directions. We will also assume that a change in pitch angle will not change the speed of the aircraft under any circumstance (unrealistic but simplifies the problem a bit). Under these assumptions the longitudinal equations of motion for the aircraft can be...

1. The pretest-posttest nonequivalent control group design is also very commonly used in psychology. Which of the following is NOT a benefit of using this design when random assignment is not possible: It reduces the threat of assignment bias It limits threats from time-related factors It provides some evidence of a potential cause-effect relationship It rules out differential history effects 2. Particularly when they do not include a control group, pre-post designs are most vulnerable to ____________-related threats to internal...
