1 Harrison, Reid R.Analog VLSI model of the fly elementary motion detectorFlies are capable of rapidly detecting and integrating visual motion information in behaviorly-relevant ways. The first stage of visual motion processing in flies is a retinotopic array of functional units known as elementary motion detectors (EMDs). Several decades ago, Reichardt and colleagues de...1998-01-01

This work takes on this challenge by means of a novel method based on complete interdisciplinarity, design process and built-in evaluations. The result is the design, construction, ...Data representation; visualization design; data environments2005
3 Freire, JulianaBeyond depth-first strategies: improving tabled logic programs through alternative schedulingTabled evaluation ensures termination for programs with finite models by keeping track of which subgoals have been called. Given several variant subgoals in an evaluation, only the fi rst one encountered will use program-clause resolution; the rest will resolve with the answers generated by the f...Alternate scheduling; SLG-WAM; Tabled logic programs1998
4 Nicoll, KathleenThe climate and environment of Byzantine Anatolia: Integrating science, history, and archaeologyThis article, which is part of a larger project, examines cases in which high-resolution archaeological, textual, and environmental data can be integrated with longer-term, low-resolution data to afford greater precision in identifying some of the causal relationships underlying societal change.2014-01-01

7 Harrison, Reid R.Fly-inspired VLSI vision sensorsEngineers have long looked to nature for inspiration. The diversity of life produced by five billion years of evolution provides countless existence proofs of organic machines with abilities that far surpass those of our own relatively crude automata. We have learned how to harness large amounts of ...2002
8 Capecchi, Mario R.; Thomas, Kirk R.High frequency targeting of genes to specific sites in the mammalian genomeWe corrected a defective gene residing in the chromosome of a mammalian cell by injecting into the nucleus copies of the same gene carrying a different mutation. We determined how the number, the arrangement, and the chromosomal position of the integrated gene, as well as the number of injected mo...Homologous recombination; Mutant genes; Mammalian genome1986
9 Riloff, Ellen M.Information extraction as a stepping stone toward story understandingHistorically story understanding systems have depended on a great deal of handcrafted knowledge. Natural language understanding systems that use conceptual knowledge structures (Schank and Abelson 1977; Cullingford 1978; Wilensky 1978; Carbonell 1979; Lehnert 1981; Kolodner 1983) typically rely on ...Information extraction; Story understanding1999
10 Capecchi, Mario R.Isolation of a suppressible nonsense mutant in mammalian cellsAn HGPRT- cell line derived from mouse L cells has been shown to have the following properties: it is CRM'; the defective HGPRT molecules are altered in the carboxyterminal peptide; the mutant cells regain HGPRT activity when ochre-suppressor tRNA is microinjected into them, but not when amber...HGPRT cell line; HGPRT activity; Ochre nonsense mutation; Mouse L cells; Mammalian cells1977
11 Harrison, Reid R.Low-power analog VLSI visual collision detectorWe have designed and tested a single-chip analog VLSI sensor that detects imminent collisions by measuring radially expansive optic flow. The design of the chip is based on a model proposed to explain leg-extension behavior in flies during landing approaches. A new elementary motion detector (EMD) c...VLSI; Visual collision detection; Elementary motion detectors2004-01-01
12 Blair, David F.MotA protein of E. coli is a proton-conducting component of the flagellar motorA number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered...MotA protein; MotA gene; Flagellar motor; Proton-conducting1990
13 Coley, Phyllis D.On turning green into goldAnthropogenic effects on the climate and biodiversity of our planet are among the most troubling and perhaps irreversible threats facing scientists, policymakers, and citizens. Yet many scientists are reluctant or unsure of how to apply their expertise in basic science to these pressing real-world p...Bioprospecting; Drug discovery; Active compounds; Panama2008
14 Bastiani, MichaelPathfinding by growth cones in the central nervous system of the grasshopper embryoIn the grasshopper embryo the morphological development of individually identified neurons can be traced prior to the onset of axonogenesis on through maturity (eg., Goodman and Spitzer, 1979). The behavior of individual growth cones can be characterized in their natural environment as they extend t...1982-06-03
15 Maloney, Thomas N.Personnel policy, costs of experimentation, and racial inequality in the Pre-World War II NorthBetween 1910 and 1940, the black population of the northern United States nearly tripled, rising from just over I million to more than 2.7 million, signaling the start of the "Great Migration" of African-Americans out of the South. As black workers entered the North, they sought positions in new sec...Race bias; Personnel policies; African Americans; Employment opportunities1999

20 Capecchi, Mario R.; Thomas, Kirk R.Swaying is a mutant allele of the proto-oncogene Wnt-1Mice homozygous for the recessive mutation swaying (SW) are characterized by ataxia and hypertonia, attributed to the malformation of anterior regions of the cerebellum. We show that SW is a deletion of a single base pair from the proto-oncogene Wnf-1. The deletion is predicted to cause premature t...Swaying allele; protooncogene Wnt-1; Mutant genes; Mutant alleles1991
21 Freire, JulianaTaking I/O seriously: resolution reconsidered for diskModern compilation techniques can give Prolog programs, in the best cases, a speed comparable to C. However, Prolog has proven to be unacceptable for data-oriented queries for two major reasons: its poor termination and complexity properties for Datalog, and its tuple-at-a-time strategy. A number of...Tabling; SLG-WAM; Prolog; XSB; Datalog1997
