Bastiani, Michael | Axons break in animals lacking β-spectrin | Axons and dendrites can withstand acute mechanical strain despite their small diameter. In this study, we demonstrate that β-spectrin is required for the physical integrity of neuronal processes in the nematode Caenorhabditis elegans. Axons in β-spectrin mutants spontaneously break. | Mutants; Dendrites; Morphology | 2007 |

Rogachev, Andrey | Effect of morphology on the superconductor-insulator transition in one-dimensional nanowires | We study the effect of morphology on the low-temperature behavior of superconducting nanowires which vary in length from 86 nm to 188 nm. A well-defined superconductor-insulator transition is observed only in the family of homogeneous wires, in which case the transition occurs when the normal resist... | One-dimensional wires; Superconductor-insulator transition; Homogeneous wires; Inhomogeneous wires; Morphology; Low-temperature behavior | 2004-05 |

Chandran, Ravi | Evolution of microstructure and phases in in-situ processed Ti-TiB composites containing high volume fractions of TiB whiskers | A series of titanium composites, with varying volume fractions of titanium monoboride (TiB) whiskers, were made by mixing various proportions of titanium (Ti) and titanium diboride (TiB2) powders followed by hot pressing. The phases present were identified by x-ray diffraction. | Morphology; diffraction; relative intensity | 1999 |

Shapiro, Michael D. | Limb diversity and digit reduction in reptilian evolution | The study of morphological rules, or trends, offered classical biologists the opportunity to address the mechanisms underlying the evolution of anatomical designs. Regularities in evolution suggested that common functional or developmental rules governed the transformation of structures. Parallelism... | Digit loss; Morphology; Adaptation | 2006 |

Haber, Matthew | Morphology, ultrastructure, and function of extrafloral nectaries in three species of Caesalpiniacae | Light and electron microscopy reveal that the morphologically well-differentiated petiolar nectaries of Ckamaecrista fasciculata, Senna hepecarpa, and S. marilandica have an unusually simple anatomy consisting of an epidermis immediately subtended by a mass of small, loosely-packed parenchyma cells.... | Extrafloral nectaries; Morphology; Ultrastructure; Function; Cutin; Phloem; Parenchyma; Chamaecrista fascicu; Senna hepecarpa; Senna marilandic | 1999 |

Seger, Jon | Sexual dimorphism in the Hymenoptera | Spectacular sex differences of many kinds occur abundantly among the wasps, bees and ants that make up the insect order Hymenoptera. In some cases these differences are so extreme that males and females of the same species have been classified in different genera for decades, until a chance observa... | Reproductive; Insect; Morphology | 1994 |
