101 Sobh, Tarek M.Modeling and recovering uncertainties in sense dataThis work examines closely the possibilities for errors, mistakes and uncertainties in sensing systems. We identify and suggest techniques for modeling, analyzing, and recovering these uncertainties. This work concentrates on uncertainties in visual sensing to recover 3-D structure and motion charac...Uncertainties; Sensing systems; Visual sensing1994
102 Baehr, WolfgangMolecular characterization of human and mouse photoreceptor guanylate cyclase-activating protein (GCAP) and chromosomal localization of the human geneGuanylate cyclase-activating protein (GCAP) is a novel Ca(2+)-binding protein that stimulates synthesis of cGMP in photoreceptors. Molecular cloning of human and mouse GCAP cDNA revealed that the known mammalian GCAPs are more than 90% similar, consist of 201-205 amino acids, and contain three ident...Amino Acid Sequence; Base Sequence; Cloning, Molecular1994

104 Bruderlin, BeatMoving into higher dimensions of geometric constraint solvingIn this paper, we present an approach to geometric constraint solving, based on degree of freedom analysis. Any geometric primitive (point, line, circle, plane, etc.) possesses an intrinsic degree of freedom in its embedding space which is usually two or three dimensional. Constraints reduce the deg...Geometric constraint solving1994

108 Morse, Michael DavidNi? revisited: reassignment of the ground electronic stateResonant two-photon ionization spectroscopy was used to study jet-cooled Ni2 produced by pulsed laser ablation of a nickel target in the throat of a supersonic nozzle using argon as the carrier gas. Spectral regions previously investigated using helium as the carrier gas were reinvestigated, and the...1994
109 Olivera, Baldomero M.Nicotinic acetylcholine receptor ligand of unique specificity, α-conotoxin ImIWe report the isolation, characterization, and total synthesis of a small peptide ligand for nicotinic acetylcholine receptors (nAChRs). It is highly active against the neuromuscular receptor in frog but noitn mice. In contrast, it induces seizures when injected centrally in mice and rats, suggesti...Conotoxins; a-conotoxin ImI1994
110 Ailion, David CharlesNMR in substitutionally disordered incommensurate (Rb1-xKx)2ZnCl4The impurity-concentration dependence of the 8 7Rb NMR line shapes and phason-induced spin-lattice relaxation rates has been studied over a wide temperature range in substitutional^ disordered incommensurate (Rb1_xKJ C)2ZnCl4 for x =0.00, 0.02, and 0.06. The results yield information on the impurity...NMR; Line shapes; Phasons; Spin-lattice; Phase fluctuations1994
111 Jewell, PaulPaleoredox conditions and the origin of bedded barites along the Late Devonian North American continental marginThe most important controls of the redox state of natural waters are the flux of organic matter from the photic zone, the degree of physical mixing, and oxygen concentrations of any connecting water masses. In coastal upwelling zones, these factors can be described with a simple box model constraine...Bedded barites; Late Devonian; Continental margin; Redox state1994
112 Hansen, Charles D.Parallel renderingMassively parallel computers have emerged as valuable tools for performing scientific and engineering computations, far outstripping the capabilities of independent workstations in both sheer floating point performance and memory capacity. As the resolution of simulation models increases, graphics ...Parallel rendering; Massively parallel processors1994
113 Hansen, Charles D.Parallel volume rendering using binary-swap compositingExisting 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
114 Freire, JulianaParallelizing tabled evaluationsSLG is a table-oriented resolution method that extends SLD evaluation in two ways. It computes the well-founded model for logic programs with negation with polynomial data complexity,and it terminates for programs with the bounded-term-size property. Furthermore SLG has an efficient sequential imple...Parallel logic programming; Tabling; Table parallelism; SLG; XSB1994
115 Battin, Margaret P.; Francis, Leslie; Jacobson, Jay A.Patients' understanding and use of advance directivesThe Patient Self-Determination Act was implemented in December 1991. Before and after its implementation, we used a structured interview of 302 randomly selected patients to determine their awareness, understanding, and use of advance directives.
