1 Brunvand, Erik L.A cell set for self-timed design using actel FPGAsAsynchronous or self-timed systems that do not rely on a global clock to keep system components synchronized can offer significant advantages over traditional clocked circuits in a variety of applications. However, these systems require that suitable self-timed circuit primitives are available for b...Self-timed systems; Actel field programmable gate arrays; FPGA1991
2 Starkey, MikeA lisp-based occam interpreterThe OCCAM programming language is an implementation of Communicating Sequential Processes and is used in a number of different areas. These areas usually require explicitly describing small-grain paralleslism. OCCAM programs formed by such descriptions can be tested for correctness by executing the...Lisp-based; Occam interpreter1991
3 Ogburn, Joyce L.Acquisitions, up, up and away: Yale University?s new acquisitions departmentAs of July 15, 1991 Yale University's Sterling Memorial Library began reconstituting an acquisition's department under Technical Services. In these days of bad news about closing departments, budget cuts and escalating serial prices, it's nice to be able to report some good news!Yale University; Sterling Memorial Library; Acquisitions1991
4 Mathews, V. JohnAdaptive algorithms for identifying recursive nonlinear systemsABSTRACT This paper presents two fast least-squares lattice algorithms for adaptive non-linear filters equipped with system models involving nonlinear feedback. Such models can approximate a large class of non-linear systems adequately, and usually with considerable parsimony in the number of coeff...1991
5 Mathews, V. JohnAdaptive polynomial filtersWhile linear filter are useful in a large number of applications and relatively simple from conceptual and implementational view points. there are many practical situations that require nonlinear processing of the signals involved. This article explains adaptive nonlinear filters equipped with polyn...1991

7 Golden, Kenneth M.Arbitrarily slow approach to limiting behaviorABSTRACT. Let f(k, t): RN x [0, oo) -- R be jointly continuous in k and t, with lim(t)--(oo) f(k, t) = F(k) discontinuous for a dense set of k's. It is proven that there exists a dense set T of k's such that, for k e T , |f(k, t) - F(k)| approaches 0 arbitrarily slowly, i.e., roughly speaking, more ...Random; Conductivity; Diffusion1991
8 Morrow, CarolynBreaking the rules: transgression and carnival in Ultimas tardes con TeresaRituals and celebrations emerge as a central structuring device in the love story that forms the center of Ultimas tardes con Teresa, Juan Marse's prize-winning novel of 1965. The narrative begins with a couple, Manolo and Teresa, strolling through the center of Barcelona during Fiesta Mayor, one o...Rituals; Society; Culture1991
9 Ogburn, Joyce L.Business of acquisitions 1991The third ALCTS Business of Acquisitions Institute was held in Boston at Emmanuel College on June 6-7,1991. These institutes are meant to convey some basic understanding of the complex function of acquiring materials for libraries to beginning acquisitions librarians or professionals with other bac...Acquisitions; Vendors; Libraries1991
10 Golden, Kenneth M.Classical transport in quasiperiodic mediaAbstract. Classical transport coefficients such as the effective conductivity or diffusivity of a quasiperiodic medium were observed [1] to depend discontinuously on the frequencies of the quasiperiodicity. For example, for a one-dimensional medium with a potential V(x) = cosx + coskx , the effecti...Transport; Diffusion; Random1991

13 Olivera, Baldomero M.; Hillyard, David R.ConotoxinsMany successful animal and plant families have developed distinctive biochemical strategies; one of the more unusual examples is found in a group of marine gastropods, the cone snails (Conus) (1). These animals have evolved a specialized biochemistry of small constrained peptides, the conotoxins. Th...Conotoxins1991
14 Brown, Francis HaroldCorrelation of tephra layers from the Western Rift Valley (Uganda) to the Turkana Basin (Ethiopia/Kenya) and the Gulf of AdenFour volcanic ashes have been mapped in Albertine Group strata (Warwire, Kaiso Village and Nyabusosi Formations) Western Rift Valley, Uganda. Three of these tuffs have geochemical fingerprints similar to tuffs in the Turkana Basin (Ethiopia, Kenya), in Afar (Ethiopia) and the Gulf of Aden, permitti...1991
15 Bohs, Lynn A.Crossing studies in Cyphomandra (Solanaceae) and their systematic and evolutionary significanceA crossing program involving eight species of Cyphomandra was instituted to elucidate systematic relationships between the taxa and evolutionary mechanisms operating in the genus. The results show that gametophytic self-incompatibility is widespread in Cyphomandra. Pollen tubes were able to reach ...Solanum maternum; Crossing studies1991
16 Couldwell, William T.Definition of the role of contemporary surgical management in cisternal and parenchymatous cysticercosis cerebriWith increasing immigration from endemic regions, the incidence of neurocysticercosis in North America is rising. This retrospective study was undertaken to examine the role of surgery in those cases presenting with large cystic parenchymal and cisternal lesions in the current era of anthelminthic a...Brain cyst; Computed tomography; Neurocysticercosis; Magnetic resonance imaging; Praziquantel; Stereotaxis1991
17 Goldberg, Robert A.Denver: Queen City of the Colorado realmIn the spring of 1921, William Joseph Simmons stepped from a train at Denver's Union Station. Dressed in a well-fitted suit emblazoned with lodge buttons, this tall, heavy-set man attracted little notice from the crowd. Few Denverites realized that on the train platform stood the self-proclaimed Imp...1991
18 Bastiani, MichaelDevelopmental expression of REGA-1, a regionally expressed glial antigen in the central nervous system of grasshopper embryosGlial cells are a large component of the developing nervous system, appearing before the onset of axon outgrowth in a variety of developing systems. Their time of appearance and their location in conjunction with developing axon pathways may allow them to define the position of axon pathways.Antibody; Axons; Pathways1991
19 Rogers, Alan R.Doubts about isonymyThe method of isonymy, developed by Crow and Mange for estimating inbreeding from surname frequencies, requires an assumption that has not been appreciated: It is necessary to assume that all males in some ancestral generation, the founding stock, had unique surnames. Because this assumption is sel...1991
20 Gopalakrishnan, GaneshEfficient symbolic simulation based verification using the parametric form of boolean expressions (rev.)We present several new techniques to make symbolic simulation based verification efficient. These techniques hinge on the use of the parametric form of a boolean expression (e.g. the parametric form for the boolean expression XQ V -<xi is the equivalent expression 3a b . (XQ = a V 6) A (xi = b), whe...Symbolic simulation; Verification1991
21 Jarrard, Richard D.Electrical properties of basalts from Sites 768 and 770Conductivity of 54 basalt samples from ODP Sites 768 and 770 was measured as a function of temperature and fluid salinity. Porosity was also measured for all samples, and cation exchange capacity was measured for 46 of the samples. Porosity measurements indicated that porosity is underestimated fo...1991
22 Couldwell, William T.Enhanced protein kinase C activity correlates with the growth rate of malignant gliomas in vitroDirect measurement of protein kinase C (PKC) activity in vitro revealed a significant increase in the activity of the enzyme in all human malignant glioma lines examined and the rat C6 tumor in comparison with control nonneoplastic astrocyte and mixed glial cultures. The total and particulate PKC ac...Brain neoplasms; Flow cytometry; Glioma; Phorbol ester; Protein kinase C1991
23 Cohen, ElaineError bounded variable distance offset operator for free from curves and surfacesMost offset approximation algorithms for freeform curves and surfaces may be classified into two main groups. The first approximates the curve using simple primitives such as piecewise arcs and lines and then calculates the (exact) offset operator to this approximation. The second offsets the contro...Error bounded; Freeform curves1991
