Normann, Richard A.; Jones, Kelly E. | Advanced demultiplexing system for physiological stimulation | A CMOS very large scale integration (VLSI) chip has been designed and built to implement a scheme developed for multiplexing/demultiplexing the signals required to operate an intracortical stimulating electrode array. Because the use of radio telemetry in a proposed system utilizing this chip may im... | Electrode Array; Stimulation; Telemetry; Microelectrodes; Transistors | 1997 |

Horch, Kenneth W. | Are the extrinsic muscles better suited for signaling joint angles or finger tip location? | We used a biomechanical model of the human long finger to determine whether the extrinsic muscles are better suited for estimating the finger's joint angles or for estimating location of the finger tip. We found that two of the extrinsic muscles together could provide information sufficient to direc... | Extrinsic muscles; Metacarpophalangeal joint; Biomechanical models | 1997 |

Christensen, Douglas A. | Dispersion effects in fiber optic interferometry | An extended analysis of the effects of uncompensated fiber dispersion on the fringe visibility of a fiber optic interferometer is developed, with particular emphasis on stellar interferometry. Both material and waveguide dispersion for single-mode, polarization-preserving fibers are considered. It... | Stellar interferometry; Fiber optics; Statistical optics | 1997 |

Horch, Kenneth W. | Electrical stimulation of the ventral lumbo-sacral spinal cord results in mixed recruitment order of quadriceps and tibialis anterior motor units | Pulse width modulated, twitch recruitment curves for quadriceps and tibialis anterior were obtained by stimulating their respective motor activation pools in the ventral lumbo-sacral portion of the spinal cord. The duration of the twitch responses were analyzed as a function of stimulus strength ... | Quadriceps; Tibialis anterior; Ventral lumbo-sacral spinal cord; Reversed recruitment | 1997 |

Gesteland, Raymond F.; Atkins, John F.; Felden, Brice; McCutcheon, John P. | Probing the structure of the Escherichia coli 10Sa RNA (tmRNA) | The conformation of the Escherichia coli 10Sa RNA (tmRNA) in solution was investigated using chemical and enzymatic probes. Single- and double-stranded domains were identified by hydrolysis of tmRNA in imidazole buffer and by lead(II)-induced cleavages. Ribonucleases T1 and S1 were used to map unpai... | Covariation; Pseudoknot; Structural Probing; 10Sa RNA; tmRNA | 1997 |

Horch, Kenneth W. | Proposed specifications for a lumbar spinal cord electrode array for control of lower extremities in paraplegia | The goal of the study was to provide specifications for a stimulating electrode array to be implanted in the lumbosacral spinal cord as part of a functional neuromuscular stimulation (FNS) system for control of lower extremity muscles in paralyzed individuals. Dual channel stimulation of the qua... | Stimulating electrode array; FNS; Functional neuromuscular stimulation | 1997 |
