A nano-electromechanical system comprises piezoelectric vertically aligned BaTiO3 nanowire arrays for energy-harvesting applications, sensors, and other applications. A jet body having an arcuate fluid jet emanator is incorporated in order to minimize size at the distal portion of a minimally sized catheter tube. It is preferably provided by a process that can produce a hydrogen feed for use in proton exchange membrane fuel cells. A tissue graft may pass through a bone tunnel and engage the loop fixation device preventing withdraw of the tissue graft back through the bone tunnel. The method further includes determining that the stop-criterion of the data model has transitioned from being outside the limitation of a preset threshold value to being inside the limitation, ending the iterations, and selecting one of the updated objects to be the reconstructed object.
