Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M. | -1 frameshifting at a CGA AAG hexanucleotide site is required for transposition of insertion sequence IS1222 | The discovery of programmed _x0001_1 frameshifting at the hexanucleotide shift site CGA_AAG, in addition to the classical X_XXY_YYZ heptanucleotide shift sequences, prompted a search for instances among eubacterial insertion sequence elements. IS1222 has a CGA_AAG shift site. A genetic analysis re... | Hexanucleotides; Heptanucleotides; Frameshifting | 2004 |

Mathews, V. John; Clark, Edward B. | A mathematical basis for the application of the modified geometric method to maximum frequency estimation | Abstract-The application of ultrasound in assessing the fetal cardiovascular system often requires the accurate estimation of maximum blood flow velocity waveforms using Doppler measurements. The modified geometric method estimates the maximum Doppler frequency as the frequency at which the vertica... | 2004 | |

Sperry, John S. | Analysis of circular bordered pit function I. Angiosperm vessels with homogenous pit membranes | A model predicted pit and vessel conductivity, the air-seed pressure for cavitation, and the implosion pressure causing vessel collapse. Predictions were based on measurements from 27 angiosperm species with circular bordered pits and air-seed pressures of 0.2-11.3 MPa. Vessel implosion pressure exc... | Functional wood anatomy; hydraulic architecture; plant biomechanics | 2004 |

Sperry, John S. | Analysis of circular bordered pit function II. Gymnosperm tracheids with torus-margo pit membranes | A model of xylem conduit function was applied to gymnosperm tracheids with torus-margo pit membranes for comparison with angiosperm vessels. Tracheids from 17 gymnosperm tree species with circular bordered pits and air-seed pressures from 0.8 to 11.8 MPa were analyzed. Tracheids were more reinforced... | Functional wood anatomy; hydraulic architecture; plant biomechanics | 2004 |

Liu, Feng | Bending of nanoscale thin Si film induced by growth of Ge islands: hut vs. dome | We perform atomistic simulations to compute bending of freestanding nanoscale thin Si film induced by strained Ge islands. We show that a larger Ge dome island can induce smaller bending than a smaller hut island and explain the surprising experimental observation for growth of Ge islands on pattern... | Bending; Nanoscale thin Si film; Ge islands; Hut islands; Dome islands; Atomistic simulations | 2004 |
