They actually do not look much different.
Use:
xlim[0 25])
with your plot and they should look reasonably similar to those in the paper.
Please do not expect to reproduce the results in any specific paper exactly. There are simply too many considerations involved, specifically the filter the paper uses and its characteristics, such as transition-region width, filter type (Butterworth, elliptic, FIR, none of which I can find stated in the paper) or other details. Frequently, ‘close enough is good enough’.

Thank you for your help, using the limits narrowed it down. I think I'll reduce the number of samples to make t cleaner. Thanks again.

As always, my pleasure!
I definitely wish you success with your workload studies! I was involved in stress responses to workload variations decades ago.
