I am searching for the above papers:

Constance F. Ramos and L. Stark , Simulation Studies of Descending and
Reflex Control of Fast Movement, J. of Motor Behavior, 1987, v. 19, 38-61

B. Hannaford and L. Stark. Roles of the elements of the triphasic control
signal. Experimental Neurology, 90:619--634, 1985.

I would be grateful if anyone has a pdf copy of them.

Thanks in advance
