Abstract: Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

Abstract: Real-time control of a prosthetic device using EMG-based locomotion state classification computes a histogram [208] of a time-frequency spectrogram [206] of the EMG data [200] sampled from muscles, classifies the histogram using if-else rules [212] as representing a locomotion steady state [216] or locomotion transition state [214] in the prosthetic device, and controls the prosthetic device using the computed transitions between locomotion modes. The classification may be based on a comparison of feature values [210] derived from the histogram and stored feature values derived from histograms of known locomotion states. Alternatively, the classification may be based on matching scores calculated from the histogram and stored histograms of known locomotion states.
