51 Christensen, Douglas A.Finite-difference time-domain modeling and experimental characterization of planar waveguide fluorescence sensorsThe finite-difference time-domain method (FDTD) is a powerful numerical technique for solving Maxwell's equations in a discretized space and time grid. Its applications have up to now been in the analysis of electrically large structures in the microwave domain, and the scope of investigations has b...Finite-difference time-domain method; Planar waveguide1992
52 Miller, Jan D.;Yu, QiangFossil resin, a value-added product from western coalCertain bituminous coals of the western United States are known to contain appreciable quantities of macroscopic fossil resin (resinite). Such resinous coals are found in the states of Arizona, Colorado, New Mexico, Utah, Washington, Wyoming, etc. The Wasatch Plateau coal field in Utah (Figure 1)...Resinite; Solvent refining; Wasatch Plateau; Hydrogenation1992
53 Free form surface analysis using a hybrid of symbolic and numeric computationDetailed analysis of many mathematical properties of sculptured models has been hindered by the fact that the properties do not have the same representation as the surface For example unit tangents surface normals and principal curvatures are typically computed at prede??ned discrete sets of ...Surface analysis1992
54 Bruderlin, BeatGDI reference manualGDI is a dialog interface tool library for C + + applications. It facilitates the design and implementation of graphical, object-oriented user interfaces for workstations equipped with a graphical display, a mouse and a keyboard. GDI's design allows for its portability onto a multitude of platforms....GDI; Dialog interface tool library1992
55 Landesman, Bruce M.Health care in a national health program: a fundamental rightDo or should Americans have a right to health care or some appropriate level of it? To explore this difficult and complex question, we must say something about rights and ways to justify them; about considerations which favor a right to health care; about what level and kind of care the right may in...Health care; Rights; Americans1992
56 Olivera, Baldomero M.; Hillyard, David R.Heterodimeric structure of the spider toxin ω-Agatoxin IA revealed by precursor analysis and mass spectrometryWe report the first molecular characterization of a precursor sequence for a small, Ca2+ channel blocking, peptide spider toxin, ω-agatoxin IA. By integrating information generated from a molecular genetic approach using agatoxin cDNAs with data provided from mass spectrometry of the mature tox...Spider toxin w-Aga-IA; Heterodimeric structure1992
57 Gopalakrishnan, GaneshHigh level optimizations in compiling process descriptions to asynchronous circuitsAsynchronous/'Self-Timed designs are beginning to attract attention as promising means of dealing with the complexity of modern VLSI technology. In this paper, we present our views on why asynchronous systems matter. We then present details of our high level synthesis tool SHILPA that can automatic...Self-timed; VLSI1992
58 Gopalakrishnan, GaneshHOP: A formal model for synchronous circuits using communicating fundamental mode symbolic automataWe study synchronous digital circuits in an abstract setting. A circuit is viewed as a collection of modules connected through their boundary ports, where each port assumes a fixed direction (input or output) over one cycle of operation, and can change directions across cycles. No distinction is ma...HOP1992
59 Silverman, Randall H.Hurricane havoc in paradiseTuesday 3 November 1992: Having previously cast absentee ballots, six conservators departed from Honolulu airport on election day for Kaua'i and a first-hand look at the damage caused by Hurricane Iniki.Recovery; Mold; Kaua'i museum1992

65 Downes, Stephen M.Importance of models in theorizing: a deflationary semantic viewIt is commonly acknowledged in science that model construction is one of the most important components of theorizing. Philosophers of science are gradually coming to acknowledge this situation, spurred on by holders of the semantic view of theories. In this paper I wish to defend a very deflationary...Theories; Mathematical; Scientific1992
66 Silverman, Randall H.Importance of permanenceColor, opacity, weight, texture, printability, and permanence - the choice of paper is critical to any successful printing job and can spell the difference between a satisfied customer and one you'll never see again. Paper is an organic material and as such begins breaking down from the moment of i...Paper; Acid free; Alkaline paper1992
67 Baehr, WolfgangIn vitro isoprenylation and membrane association of mouse rod photoreceptor cGMP phosphodiesterase alpha and beta subunits expressed in bacteriaWe investigated the specificity of CAAX box-related isoprenylation of rod photoreceptor cGMP phosphodiesterase (PDE) subunits expressed in bacteria and the consequences of this modification on rod disk membrane association. Full-length cDNA sequences of the alpha and beta subunits of mouse PDE, inse...Chromatography, High Pressure Liquid; Electrophoresis, Polyacrylamide Gel; Molecular Sequence Data1992
68 Adler, Frederick R.Information collection and spread by networks of patrolling antsTo study how a social group, such as an ant colony, monitors events occurring throughout its territory, we present a model of a network of patrolling ants engaged in information collection and dissemination. In this network, individuals follow independent paths through a region and can exchange sign...Patrolling network; ant colony; information-gathering1992

71 Beckerle, Mary C.Interaction between zyxin and α-actininZyxin is an 82-kD protein first identified as a component of adhesion plaques and the termini of stress fibers near where they associate with the cytoplasmic face of the adhesive membrane. We report here that zyxin interacts with the actin cross-linking protein α-actinin.Zyxin; Actinin; Actin1992
72 Firmage, Edwin B.Lane lecture: Law and beyond law: a new humanityThe Cold War is finally over, Soviet Communism has collapsed along with the Soviet-sponsored regimes in Eastern Europe.

73 Christensen, Douglas A.Laser diode coherence length variation with drive current: a tool for dispersion measurementsA visible light (670nm) laser diode was used as a variable coherence length source to measure dispersion characteristics in single-mode fibers. The diode's spectral width, measured against increasing drive current, was found to change from about 16 nanometers to less than 0.2 nanometer. The corresp...Laser diode; Fiber interferometry1992
74 Morse, Michael DavidLaser vaporization generation of Y ??B+, Y ??B+, and YAI+ for electron spin resonance studies in neon matrices at 4 K: comparison with theoretical calculationsThe first spectroscopic investigation of 89Y 10B+, 89Y 11B+, and 89Y 27Al+ is reported, revealing that both of these diatomic cation radicals have X 4?- electronic ground states.

Results for the d?Ad?B?? states of Ni?, the d?Nid??cu?? states of NiCu, and the d?Ni(?F)d??cu???*? excited states of NiCuA ligand-field theory has been developed for transition-metal diatomics having electronic configurations of d?Ad??B??, d?Ad?B?? and d?A(?F)d??B???*?. The theory treats each atom as a point charge and includes spin-orbit interactions. No contributions due to d-orbital chemical bonding are included. ...1992
