Previous work suggests that to restore postural stability for individuals with lower-limb amputation, ankle-foot prostheses should be designed with a flat effective rocker shape for standing. However, most commercially available ankle-foot prostheses

Many Service members and Veterans with lower-limb amputations have the potential for high function and the desire to resume physically demanding occupations that require them to carry heavy loads (e.g., military service, firefighters, farmers, ranche

In recent years, numerous prosthetic ankle-foot devices have been developed to address the demands of sloped walking for individuals with lower-limb amputation. The goal of this study was to compare the performance of a passive, hydraulic ankle-foot

Bis-anthracenyl and bis-thienyl polyenes have been synthesized using Wittig methodology. These polyenes can be oxidatively doped with SbCl5 to yield bipolaron-like charge states that can be cast as thin film composites. X (3) measurements performed b

Several approaches have been suggested during the past few years for increasing third order nonlinearity in organic compounds. In general, these have focused on manipulation of the effective conjugation length of the pi-electron framework to maximize

We study absolute cross section of simultaneous two-photon absorption (TPA) in a series of porphyrins and tetraazaporphyrins by 100-fs-duration pulses in two ranges of laser wavelength, from 1100 to 1500 nm and from 700 to 800 nm. The cross section i

Classical photodynamic therapy (PDT) has a drawback of limited penetration of visible light. It has been proposed that by utilizing two-photon absorption (TPA), where illumination is carried out at near-IR wavelengths falling into tissue transparency
