In this paper, we present a simple and portable prototype device which simulates the surface EMG signal in order to test myoelectric prostheses with a currently unavailable level of precision.

The fibula flap is commonly used to reconstruct the tibia. This has risk of postoperative fracture despite long-term non–weight bearing. A flap using noncircumferential distal femur is proposed.

Test the biomechanical properties of femurs that have undergone reaming with the Reamer Irrigator Aspirator (RIA) device with an aim to prove no difference in torsional strength between matched pairs.

It is shown that the 33 complex rays in three dimensions used by Penrose to prove the Bell-Kochen-Specker theorem have the same orthogonality relations as the 33 real rays of Peres, and therefore provide an isomorphic proof of the theorem.

Mutually unbiased bases (MUBs) in complex vector spaces play several important roles in quantum information theory.

Isoprenoids are a highly diverse and important group of natural compounds. The enzyme 1-deoxy-dxylulose-5-phosphate reductoisomerase (DXR) catalyzes a key regulatory step in the non-mevalonate isoprenoid biosynthetic pathway in eubacteria and in plant plastids.
