Gesteland, Raymond F.; Atkins, John F.; Weiss, Robert B. | Slippery runs, shifty stops, backward steps and forward hops: -2, -1, +1, +2, +5 and +6 Ribosomal frameshifting | Frameshift mutations frequently express residual levels of gene activity; that is, they are often leaky. This leakiness can be used as a tool to define the functional components that affect the reading frame during gene expression. Recent technological advances in the capability to efficiently bu... | Molecular Sequence Data; Mutation; RNA, Transfer; Frameshifting | 1987 |

Horch, Kenneth W. | Intrafascicular electrodes for nerve stimulation | We have designed a new type of intrafascicular, implanted electrode for stimulating peripheral nerves to elicit muscle contraction. The electrode requires low current to stimulate the nerve fibers, provides a fine control of muscular force, and causes little or no tissue reaction. it is of potential... | Intrafascicular electrodes; Peripheral nerve; Neural recordings | 1988 |

Christensen, Douglas A. | Introduction to biomedical engineering: biomechanics and bioelectricity - part I | Intended as an introduction to the field of biomedical engineering, this book covers the topics of biomechanics (Part I) and bioelectricity (Part II). Each chapter emphasizes a fundamental principle or law, such as Darcy's Law, Poiseuille's Law, Hooke's Law, Starling's law, levers and work in the a... | Biological membranes; Poiseuille's law; Hooke's law; Starling's law of the heart; Matlab | 2009 |

Christensen, Douglas A.; Andrade, Joseph D. | Improved sensitivity in ellipsometry of thin biochemical films by employing sublayers | Ellipsometry is widely used for investigating the optical properties of thin films on planar substrates, including films of adsorbed proteins or polymers. The average thickness and effective refractive index of the adsorbed layer are calculated by measuring the A and ¥ ellipsometry parameters. Unfo... | Biochemical films; SiO2 sublayer | 1990 |

Christensen, Douglas A. | Pulsed Schlieren system for visualizing beams from phased-array HIFU applicators | We have assembled a Schlieren system for imaging the beam patterns from HIFU transducers in water to verify the desired beam focusing and direction. It consists of a high power (65 mW) short-pulse (as short as 2 ns) laser emitting at 658 nm, a beam expander/spatial filter, water tank, 400 Jim round ... | Ultrasound beam patterns; Pulsed laser; Wavefronts | 2007 |

Horch, Kenneth W. | Separation of action potentials in multiunit intrafascicular recordings | Classification of action potentials in multiunit recordings was based on the use of various types of features to uniquely characterize action potentials from different cells. We compared classification results obtained using three types of descriptive features: digitized data points, amplitude and ... | Long-term implantable intrafascicular electrodes; Nerve recordings; Simulated neural data | 1992 |

Christensen, Douglas A.; Horch, Kenneth W. | Accelerated dual-degree BS/MS program - experience with the first three years | We have initiated a pilot program that accelerates the studies of a small group of highly qualified students early in their college careers and allows them to earn both a bachelor's degree and a master's degree in about four years after starting college. It does this by introducing them early to res... | Accelerated dual-degree program | 2004 |

Christensen, Douglas A. | Modeling sources in the FDTD formulation and their use in quantifying source and boundary condition errors | The modeling of voltage and current sources as either added or replaced sources in FDTD simulations is described and their differences discussed in terms of a transmission line analogy. An infinitesimal current element (ICE) is used to illustrate the validation of added source modeling and to study... | Finite-difference time-domain method; Infinitesimal current element | 1995-04 |

Normann, Richard A.; Campbell, Patrick K.; Jones, Kelly E. | 100 electrode intracortical array: structural variability | A technique has been developed for fabricating three dimensional "hair brush" electrode arrays from monocrystalline silicon blocks. Arrays consist of a square pattern of 100 penetrating electrodes, with 400 microns interelectrode spacing. Each electrode is 1.5mm in length and tapers from about 100 m... | Microelectrode arrays; Stimulation; Micromachining | 1990 |
