comment Is there a way to simplify a symbolic expression at assignment, once-for-all?
In your example you might just as well use a direct (not delayed) definition , f1[x_] = Simplify[Sqrt[x^2],x>0]. This question would be improved (for future reference ) if you could think up an example where Simplify does something useful, yet the function requires a delayed definition.

comment Import command gives different solution to equation than cut & paste
you keep using different file names, are you sure they are the same? ie is uce1_rates_SMALL_.csv the same file with a differnt extension? (There is no reason to change extensions for mathematica's sake by the way, supplying the type extension causes Import to ignore the file extension )

Can you do Import[filename,"Lines"] and post the first few lines?

getting closer.. your delimiters need to be in brackets, {"StartOfData"}

comment Read data from file starting at a certain point
you can not Import columns {1,2,3} because the lines with text do not always have three items. Just Import[ file, "Data" ]. If you want the three columns of data add a "{1,3}" as a third argument to Take in my second example

comment Two identical functions give different answers
confirmed the lexicographical ordering of the symbol names being subtracted for the Cos argument is the distinction here. Interestingly changing to Cos[u+t] fixes it.
