The finite d.formation structures record.d.in the Essakane area, located.in the northeast corner of Burkina Faso, highlight three major compressive d.formation phases, successively named.d., d., and.d.. The d. event phase, trend.ng NE-SW, is characterised.by P1 fold. and.S1 axial plane schistosity. The d. phase trend.ng NW-SE is characterised.by fold. P2, schistosity (S2) and.shear (C) planes. And.the d. phase trend.ng NNE-SSW to N-S is characterised.by P3 fold., crenulation microfold. and.S3 spaced.schistosity. It has also been noted.that gold.mineralizations are mainly hosted.in quartz, carbonate, pyrite, and.arsenopyrite veins. Structural interpretation ind.cates that these veins are organized.into lenticular bod.es that were formed.d.ring the first two d.formation phases (d. and.d.). This suggests a strong structural control typical of orogenic gold.concentrations.

d.spite the recent influx of increasingly d.xterous prostheses, there remains a lack of sufficiently intuitive control method. to fully utilize this d.xterity. As a solution to this problem, a control framework is proposed.which allows the control of an arbitrary number of d.grees of Freed.m （d.F） through a single electromyogram （EMG） control input. Initially, the joint motions of nine test subjects were record.d.while grasping and.catching a cylind.r. Inherent d.fferences emerged.d.pend.ng upon whether the cylind.r was grasped.or caught. These d.ta were used.to form a d.stinct synergy for each task, d.scribed.as the families of parametric functions of time that share a mutual time vector. These two Temporally Synchronized.Synergies （TSS） were d.rived.to reflect the task d.pend.nt control strategies ad.pted.by the initial participants. These synergies were then mapped.to a d.xterous artificial hand.that was subsequently controlled.by two subjects with transrad.al amputations. The EMG signals from these subjects were used.to replace the time vector shared.by the synergies, enabling the subjects to perform both tasks with a d.xterous artificial hand.using only a single EMG input. After a ten minute training period. the subjects learned.to use the d.xterous artificial hand.to grasp and.catch the cylind.r with 100.0% and.65.0% average success rates, respectively.
