Harrison, Reid R. | Micropower circuits for bidirectional wireless telemetry in neural recording applications | State-of-the art neural recording systems require electronics allowing for transcutaneous, bidirectional data transfer. As these circuits will be implanted near the brain, they must be small and low power. We have developed micropower integrated circuits for recovering clock and data signals over ... | Micropower circuits; Neural recording systems; Low-power CMOS circuits, RF telemetry; Transcutaneous data link; Transmitter | 2005-01-01 |

Hansen, Charles D. | Parallel volume rendering using binary-swap compositing | Existing volume rendering methods, though capable of very effective visualizations, are computationally intensive and therefore fail to achieve interactive rendering rates for large data sets. Although computing technology continues to advance, computer processing power never seems to catch up to th... | 1994 | |

Venkatasubramanian, Suresh | Multiple target tracking with RF sensor networks | RF sensor networks are wireless networks that can localize and track people (or targets) without needing them to carry or wear any electronic device. They use the change in the received signal strength (RSS) of the links due to the movements of people to infer their locations. In this paper, we cons... | 2014-01-01 | |

Schmidt, Meic H.; Apfelbaum, Ronald I. | Chylorrhea: a rare complication of thoracoscopic discectomy of the thoracolumbar junction | The thoracic duct along with the cisterna chyli is a major lymphatic pathway near the anterior thoracolumbar spine. Despite the fragile nature of the lymphatic system and its proximity to the spinal column, chylorrhea is rarely encountered by spine surgeons. The authors present a unique case of chyl... | Chylous leak; Thoracoscopy; Thoracic spine; Thoracoscopic discectomy; Thoracolumbar junction; Chylorrhea | 2007 |

Brown, Francis Harold | Dating | There are basically three lines of investigation that are involved in geochronology ? the dating of rocks and other earth materials. First, there are the physical and chemical dating methods which give us numerical estimates of age. Second, there is the reconstruction of the order of events in sec... | 1984 | |

Kestle, John R. W. | Intervertebral disc embolization resulting in spinal cord infarction | A case of spinal cord infarction resulting from embolization of fibrocartilaginous intervertebral disc material is presented. Cases from the literature are reviewed and the theories of pathogenesis are discussed. In all reported cases the diagnosis was not made until postmortem examination. | Spinal cord infarction; Nucleus pulposus; Intervertebral disc; Embolization | 1989 |

McDaniel, Susan | Older women: their quest for justice and peace | Myths, misconceptions and stereotypes about women and about older people combine in ways that prevent us from noticing some promising new developments in the quest for justice and peace. A popular stereotype sees the person working toward peace and justice as youthful, and significantly, often male.... | Women; Peace; Justice | 1988 |

Kestle, John R. W. | Ventriculoperitoneal shunts in children: indications, equipment and techniques | The decision to implant a ventriculoperitoneal shunt in a child with ventriculomegaly should not be taken lightly. Once a shunt has been implanted, it is very difficult to determine that it is no longer necessary, and therefore the initial decision is very important. Sometimes the need is obvious, s... | 2008 | |

Sobh, Tarek M. | Prototyping a robotic manipulator and controller | Building a robot and its environment (control, software, hardware, simulation, etc) is a complex task that requires the efforts of an experienced engineering team. Once a robot model has been chosen and a design has been agreed upon, it becomes difficult to make design changes without affecting the ... | Robotic manipulator; Robotic controller; Prototyping | 1993 |

Cohen, Elaine | A triangulation-invariant method for anisotropic geodesic map computation on surface meshes | This paper addresses the problem of computing the geodesic distance map from a given set of source vertices to all other vertices on a surface mesh using an anisotropic distance metric. Formulating this problem as an equivalent control theoretic problem with Hamilton-Jacobi-Bellman partial different... | 2012-01-01 | |

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 |

Capecchi, Mario R. | Mice with cardiac-restricted angiotensin-converting enzyme (ACE) have atrial enlargement, cardiac arrhythmia, and sudden death | To investigate the local effects of angiotensin II on the heart, we created a mouse model with 100-fold normal cardiac angiotensin-converting enzyme (ACE), but no ACE expression in kidney or vascular endothelium. This was achieved by placing the endogenous ACE gene under the control of the α-myo... | Atrial enlargement; Cardiac arrhythmia; ACE | 2004 |

Hansen, Charles D. | Fast stereoscopic images with ray-traced volume rendering | One of the drawbacks of standard volume rendering techniques is that it is often difficult to comprehend the three-dimensional structure of the volume from a single frame; this is especially true in cases where there is no solid surface. Generally, several frames must be generated and viewed sequent... | Volume rendering; Ray tracing; Stereoscopic images; Reprojection | 1994 |
