Capecchi, Mario R. | Altered enzymes in drug-resistant variants of mammalian tissue culture cells. | Two selective procedures are compared in an effort to isolate variants of mouse L cells containing structural gene mutations. Among the resulting variant cloned cell lines are found two types of alterations in theenzyme hypoxanthine phosphoribosyl transferase (EC 2.4.2.8.) (1): enzyme with altered ... | Drug Resistance; Azaguanine; Clone Cells; Hypoxanthines | 1973-11 |

Symko, Orest George | Background signals in SQUID magnetometers | Since a SQUID magnetometer is an extremely sensitive device capable of detecting minute magnetic flux changes in a sample, it will also detect unwanted signals from materials near the magnetometer. The presence of temperature dependent "background signals" limits the accuracy of measurements of ... | SQUID magnetometer; Background signals | 1974 |

Normann, Richard A. | Control of retinal sensitivity. I. Light and dark adaptation of vertebrate rods and cones | Rods and cones in Necturus respond with graded hyperpolarization to test flashes spanning about 3.5 log units of intensity. Steady background levels hyperpolarize the rods, and the rod responses become progressively smaller as background level is increased. In cones, higher background levels reduce... | Retina;Light and Dark Adaptation; Recepters; Bipolars; Ganglion Cells | 1974 |

Mattis, Daniel C. | New wave-operator identity applied to the study of persistent currents in 1D | We show that a large class of backward-scattering matrix elements involving Δk ~ + 2k F vanish for fermions interacting with two-body attractive forces in one dimension. (These same matrix elements are finite for noninteracting particles and infinite for particles interacting with two-body repulsiv... | Persistent current; Supercurrents | 1974 |

Miller, Neil Joseph | Removal of noise from a voice signal by synthesis | This report describes research into the problem of rectification of sound recordings made under adverse conditions and communicated and recorded with a great deal of noise. In the course of this research, a number of refinements have been made to the process of digital speech synthesis through new v... | Rectification; Homomorphic vocoder; Digital speech synthesis; Filtering device | 1974 |

Colas-Baudelaire, Patrick | Digital picture processing and psychophysics: a study of brightness perception | A computer driven display system was used to study brightness contrast phenomena, in a project motivated by research in digital picture processing. The modeling approach was that of Stockham and Davidson: the visual system is modeled as the cascade of a linear system (eye optics) and a multiplicati... | Digital picture processing; Computer driven display system; Brightness contrast | 1974 |

Boll, Steven F. | Selected methods for improving synthesis speech quality using linear predictive coding: system description, coefficient smoothing and streak | This report develops two generalizations of the standard Linear Predictive Coding (LPC) implementation of a narrow band speech compression system. The purpose of each method is to improve the speech quality that is available from a standard LPC system. | Linear Predictive Coding; LPC; Speech compression system; Pitch excited system | 1974 |

Vickers, Donald Lee | Sorcerer's apprentice: head-mounted display and wand | Sorcerer's Apprentice is an interactive computer graphics system utilizing a head-mounted display and at three-dimensional wand. The system allows three-dimensional interaction with line drawings which are displayed in real time, that is about 20 frames per second. The display, worn like a pair of e... | Sorcerer's apprentice; Head-mounted display; Three-dimensional wand | 1974 |
