Carter, Tony M. | Cascade: hardware for high/variable precision arithmetic | The Cascade hardware architecture for high/variable precision arithmetic is described. It uses a radix-16 redundant signed-digit number representation and directly supports single or multiple precision addition, subtraction, multiplication, division, extraction of the square root and computation... | | 1989 |

Bohs, Lynn A. | Solanum allophyllum (Miers) Standl. and the generic delimitation of Cyphomandra and Solanum (Solanaceae) | Solanum allophyllum has previously been placed in Cyphomandra and in Solarium. This species has a number of morphological features not found in Cyphomandra, but has been included in the genus because it has a similar growth habit, three-leaved sympodial units with inflorescences in branch forks, and... | Solanum allophyllum; Cyphomandra | 1989 |

Sperry, John S. | Anatomy of the palm Rhapis excelsa, IX. Xylem structure of the leaf insertion | STEMS OF PERENNIAL PLANTS, particularly trees, represent a considerable investment in biomass. Trees can survive even under the most adverse conditions, but only if the hydraulic integrity of the stem is preserved. A very important and vulnerable part of the stem is the xylem. As water is pulled int... | Palm stems; Palm stem anatomy; Palm leaves; Leaf insertion; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column | 1983 |

Sperry, John S. | Hydraulic architecture of palms | The water transport and storage system of palms is adapted to maintain the primary stem xylem functional over the life of the shoot, and in spite of severe drought. However, our structural information far exceeds our knowledge of vascular function, and these functional considerations bring more que... | Hydraulic architecture; Rhapis excelsa; Cavitation | 1995 |

Shapiro, Michael D. | Genetic architecture of parallel armor plate reduction in threespine sticklebacks | How many genetic changes control the evolution of new traits in natural populations? Are the same genetic changes seen in cases of parallel evolution? Despite long-standing interest in these questions, they have been difficult to address, particularly in vertebrates. We have analyzed the genetic bas... | Genetic changes; Plate number; Genetic mapping | 2004 |

Efros, Alexei L. | Sensor-based distributed control scheme for mobile robots | In this paper we present a sensor-based distributed control scheme for mobile robots. This scheme combines centralized and decentralized control strategies. A server-client model is used to implement this scheme where the server is a process that caries out the commands to be executed, and each clie... | Sensor-based; Distributed control scheme | 1995 |

Shapiro, Michael D. | Genetic architecture of skeletal convergence and sex determination in ninespine sticklebacks | The history of life offers plentiful examples of convergent evolution, the independent derivation of similar phenotypes in distinct lineages [1]. Convergent phenotypes among closely related lineages (frequently termed "parallel" evolution) are often assumed to result from changes in similar genes or... | Convergent evolution; Skeletal convergence; Pungitius pungitius; Gasterosteus aculeatus; Comparative genetics | 2009-07 |

Sperry, John S. | Observations of reaction fibers in leaves of dicotyledons | HALLE, OLDEMAN, AND TOMLINSON (1978) have discussed the transference of function between compound leaves and plagiotropic branches in the context of tree architecture. In trees conforming to Cook's model (see Halle, Oldeman, & Tomlinson, 1978), plagiotropic branches resemble compound leaves in their... | Reaction fibers; Compound leaves | 1982 |

Coley, Phyllis D. | What's up? Perspectives from the first international forest canopy conference at Sarasota, Florida, 1994 | Jumars, caribineers, pole pruners, tree bicycles, Bosun's chairs, booms, peconhas . . . these terms are not listed in most biological dictionaries. Nor are construction cranes or large treehouses or hot-air dirigibles listed as priority equipment for any scientific laboratories. But these are th... | | 1995 |

Goller, Franz | Lateralization as a symmetry breaking process in birdsong | The singing by songbirds is a most convincing example in the animal kingdom of functional lateralization of the brain, a feature usually associated with human language. Lateralization is expressed as one or both of the bird's sound sources being active during the vocalization. Normal songs require ... | Lateralization; Syringeal muscles; Respiration; Gating | 2007-03 |

Sperry, John S. | Evaluation of Murray's law in Psilotum nudum (Psilotaceae), an analogue of ancestral vascular plants | Previous work has shown that the xylem of seed plants follows Murray's law when conduits do not provide structural support to the plant. Here, compliance with Murray's law was tested in the stem photosynthesizer Psilotum nudum, a seedless vascular plant. Psilotum nudum was chosen because the central... | Conduit furcation number; hydraulic architecture; Murray's law | 2005 |

Beckerle, Mary C.; Hoffman, Laura M. | Targeted disruption of the murine zyxin gene | Zyxin is an evolutionarily conserved protein that is concentrated at sites of cell adhesion, where it associates with members of the Enabled (Ena)/vasodilator-stimulated phosphoprotein (VASP) family of cytoskeletal regulators and is postulated to play a role in cytoskeletal dynamics and signaling. | Zyxin | 2003 |

Miller, Joel Steven | Crystal engineering or crystal mysticism? A case study | The de novo design and synthesis of a crystalline motif of a substance is a holy grail for a growing number of organic and inorganic synthetic chemists. Achievement of targeted architectural arrangements is less reliable as the complexity increases. Simple substitution of, for example, alkyl penda... | Synthesis, Structure, Chemistry | 2005 |

Goller, Franz | Low-dimensional dynamical model for the diversity of pressure patterns used in canary song | During song production, oscine birds produce large air sac pressure pulses. During those pulses, energy is transferred to labia located at the juncture between the bronchii and the trachea, inducing the high frequency labial oscillations which are responsible for airflow modulations, i.e., the utt... | Serinus canarias; Air sac pressure | 2009-04 |
