comment Change “ListPlot” to 16 bit accuracy?
your syntax is wrong, # should be some symbol, eg to16bits[x_] := Floor[2^16*x]*2.^-16 I cant see what that will accomplish though, i.m sure that tiny roundoff is too small to discern on a plot. (Or do you mean to do that rounding at every iteration?)

I'm afraid you will need to work out your own finite difference scheme.

comment Jump boundary conditions
not sure why the downvote. Anyway NDSolve is not so general that it can handle any sort of bc you can dream up, even if mathematically valid. In this case the pde's look to be fully decoupled, so solve first for u, then use that solution as a bc as you solve for v and so on. Alternately formulate as a single unknown on domain x,0,4

do the assumptions matter? You should only need s!=0

Put your cursor on Exp and push F1 . You managed to invent two different incorrect expression syntaxes for the exponential.

comment Inconsistent Integrate behavior?
you can do this: Integrate[q0/(-1 + b q0^2), {q0, 0, A}] /. b -> 12 to get your conditional expression. I agree this is an inconsistency. You can also see the issue if you do Integrate[q0/(-1 + 12 q0^2), {q0, 0, 1}] you get a correct message that the integral does not converge while Integrate[q0/(-1 + 12 q0^2), {q0, 0, A}] /. A -> 1 gives an erroneous result.
