27 Christensen, Douglas A.FDTD modeling in the design of optical chemical sensor structuresThe finite-difference time-domain method (FDTD) is a numerical technique for solving Maxwell's equations in a discretized space and time frame. It has been used extensively in the analysis of electrically large structures in the microwave domain, but has only recently been applied to optical proble...Finite-difference time-domain method; Immunochemical fluorosensors; Planar waveguides1991
28 McDaniel, SusanFeminist scholarship in sociology: transformation from within?Few revolutions, epistemological or otherwise, begin in academia. And yet, knowledge producers always play some role in revolutions of any kind, including epistemological revolutions. This paper is in the spirit of recent debates in the Canadian Journal of Sociology about the end of modern sociology...Feminist sociology; Social reality1991
29 Vardeny, Zeev ValentineFemtosecond dynamics of the nonlinear optical response in polydiethynylsilaneWe have measured the femtosecond dynamics of the nonlinear optical response xc3' in polydiethynylsilane ( C4H2SiBu2)x, a novel class of r-conjugated polymers incorporating Si, using degenerate four-wave mixing and photoinduced absorption techniques. In resonance conditions at 620 nm we found x (3) ...Polydiethynylsilane; Femtosecond dynamics; Nonlinear optical response; Pi-conjugated polymers1991
30 Gesteland, Raymond F.; Atkins, John F.Frameshifting in gene 10 of bacteriophage T7Gene 10 of bacteriophage T7, which encodes the most abundant capsid protein, has two products: a major product, 10A (36 kDa), and a minor product, 10B (41 kDa). 10B is produced by frameshifting into the -1 frame near the end of the 10A coding frame and is incorporated into the capsid. The frameshift...Frameshifting; Bacteriophage T7; RNA, Viral; Gene Expression1991
31 Gopalakrishnan, GaneshFrom process-oriented functional specifications to efficient asynchronous circuitsA methodology for high-level synthesis and performance optimization of asynchronous circuits is described. A specification language called hopCP which is based on a simple extension to classical flow graphs is introduced. The extension involves the addition of expression actions to a flow graph, to ...Synthesis; Performance optimization1991
32 Cotter, Neil E.Generality Vs. speed of convergence in the cart-pole balancerThis paper compares the speed of convergence to an optimal solution of four controllers for the problem of balancing a pole on a cart. We demonstrate that controllers whose design is tailored specifically to the cart-pole problem (i.e. less general) converge more rapidly to an optimal solution. How...Cart-pole balancer; Generality; Speed of convergence1991
33 Jarrard, Richard D.Geochemical results from wireline logs in the Celebes Sea, Sites 767 and 770 of Leg 124Geochemical well logs were obtained at ODP Sites 767 and 770 in the Celebes Sea. The log data obtained at sea have been corrected for borehole size changes, the effects of drilling fluids, and logging-speed variations. The processed logs are then used to calculate the amounts of the three major ra...1991
34 Jewell, PaulGeochemistry and paleoceanographic setting of Central Nevada bedded baritesThe bedded barite deposits of central Nevada are hosted by rocks of the Roberts Mountains allochthon and constitute the largest barite reserves in North America. Detailed geochemical studies of three barite deposits in the Devonian Slaven Chert indicate that rocks surrounding the barite have elevate...Bedded barites; Roberts Mountains allochthon; Late Devonian1991
35 Jarrard, Richard D.Geophysical properties of oceanic crust at Sites 768 and 770Velocity, density, resistivity, and neutron-porosity logs were recorded in virtually the entire 222-m-thick section of basaltic back-arc crust drilled at Site 768 and through the 106-m section of MORB crust at Site 770. Our analysis of these logs and comparison with measurements on discrete cores pe...1991
36 Morse, Michael DavidThe ground state and excited ?-hole states of CuAuResonant two-photon ionization spectroscopy has been applied to jet-cooled diatomic CuAu. Eight band systems have been observed, rotationally resolved, and analyzed. The ground state is X??+ in symmetry, deriving from the 3d??Cu 5d??Au, ?? molecular configuration. Its bond length has been determined...1991
37 Gopalakrishnan, GaneshHierarchical action refinement: a methodology for compiling asynchronous circuits from a concurrent HDLA hardware specification formalism called hopCP is introduced, hopCP provides an uniform notation t o describe the causal relationships between a set of nonatomic actions which capture the computational, concurrency, control and communication aspects of hardware behavior. A systematic approach to sy...Hierarchical action refinement; Hardware specification formalism; hopCP1991
38 Jarrard, Richard D.High-resolution geochemical variations at Sites 723, 728, and 731: a comparison of X-ray fluorescence and geochemical logsGeochemical logging is a routine part of the Ocean Drilling Program, yet the reliability of ODP geochemical logs has rarely been evaluated quantitatively. On ODP Leg 117, geochemical logs were obtained at Sites 723, 728, and 731. We report here an evaluation of ODP geochemical log quality based on h...1991
39 Gopalakrishnan, GaneshhopCP: A concurrent hardware description languagehopCP is a language for the specification, simulation, and synthesis of hardware systems. hopCP captures the behavior of a hardware system by specifying the causal relationships between actions that the system can perform. No specific timing discipline is implied by a hopCP specification. Hence, hop...hopCP; Hardware systems1991

45 Barusch, AmandaIntergenerational relations in contemporary China: descriptive findings from ShanghaiWith over one billion people, China accounts for nearly a quarter of the world's population. It also has the largest population of elderly (60 and over) living under one government (approximately 80 million).

47 Lindstrom, Gary E.Modularity meets inheritanceWe "unbundle" several roles of classes in existing languages, by providing a suite of operators independently controlling such effects as combination, modification, encapsulation, name resolution, and sharing, all on the single notion of module. All module operators are forms of inheritance. Thus, ...Modularity; Jigsaw computer tool1991
