Adler, Frederick R. | Defended fortresses or moving targets? Another model of inducible defenses inspired by military metaphors | We use a common framework to compare three models of plant strategies to confront herbivory: constitutive defense, optimal inducible defense, and the "moving target." Plants with constitutive defenses retain a fixed defensive phenotype. Plants with optimal inducible defenses respond to attack by inc... | Constitutive defense; optimal inducible defense; phenotype | 1994 |

Olivera, Baldomero M. | Defining a clade by morphological, molecular, and toxinological criteria: distinctive forms related to Conus praecellens A. Adams, 1854 (Gastropoda: Conidae) | We carried out a definition of the Conus praecellens A. Adams, 1854, species group using a combination of comparative morphological data, molecular phylogeny based on standard genetic markers, and toxinological markers. Prior to this work, Conus praecellens was generally postulated to belong to a cl... | Turriconus; 12SrRNA sequences; Phylogenetic analysis; Conus praecellens; Exogenes | 2010 |

Wu, Yong-Shi | Deformed Hubbard operator, bosonization, and phase diagram of the one-dimensional t-J model | We present an analytic study of the phase diagram of the one-dimensional t-J model and a couple of its cousins. To deal with the interactions induced by the no double occupancy constraints, we introduce a deformation of the Hubbard operators. When the deformation parameter ∆ is small, the induced... | Hubbard operator; Bosonization; Deformation; t-J model | 2002-10 |

Farmer, Colleen G. | Dendrobates auratus (green and black poison dart frog). Larval Predation | Dendrobates auratus was intentionally introduced onto the island of O'ahu, Hawai'i in 1932 from Taboga Island, Panama for mosquito control. Phelsuma laticauda was accidentally introduced from Madagascar in 1996 to the University of Hawaii at Manoa. Both species are well established in the Manoa Val... | Dendrobates auratus; Phelsuma laticauda | 2007 |

Keller, Robert M. | Denotational models for parallel programs with indeterminate operators | Several approaches to networks of concurrently-operating modules involving indeterminacy are discussed. Techniques for representing the denotational semantics of such networks, and for verifying properties of them, are presented, including an oracle approach, an axiomatic approach, a data-type reduc... | Denotational models; Indeterminate operators | 1977 |

Adler, Frederick R. | Departure time versus departure rate: how to forage optimally when you are stupid | Foragers unable to leave a patch at the optimal moment must act as constrained foragers. Extending the results of Houston and McNamara (1985), we compare a blundering forager that leaves patches at a constant rate with an unconstrained optimal forager that leaves patches at the optimal time. | Blundering Foragers; Foraging; Marginal Value Theorem | 1999 |

Gondolo, Paolo | Detectability of the Sgr dwarf leading tidal stream with Auger, EUSO, or OWL | We point out that if heavy metastable particles composing the dark matter of our galaxy are responsible for the ultrahigh energy cosmic rays (UHECR) then the leading tidal stream of the Sagittarius dwarf galaxy could be detected through UHECR. The signal would be an anisotropy in the UHECR flux sma... | Sagittarius dwarf galaxy; Sgr stream; anisotropy | 2004-07 |

Gondolo, Paolo | Detectability of weakly interacting massive particles in the Sagittarius dwarf tidal stream | Tidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing ~(0:3-23)% of the local density of our galactic halo. If the Sagittarius galaxy contains dark matter in the form of weakly interacting massive particles (WIMPs), the ext... | WIMP; Weakly interacting massive particles; Sagittarius dwarf galaxy; Recoil energy; Sgr stream | 2005-02 |

Vardeny, Zeev Valentine | Detection of electronic excited states in conjugated polymers by picosecond transient strain spectroscopy | We describe a new type of spectroscopy based on picosecond transient strain in absorption photomodulation that can be used to detect and identify both allowed and forbidden optical transitions in solid thin films.

Ailion, David Charles | Detection of slow modulation wave diffusion in incommensurate barium sodium niobate by 93Nb 2D exchange NMR | 93Nb two-dimensional (2D) exchange NMR was used to study ultraslow motions in incommensurate barium sodium niobate (BSN) in the temperature range 500 - 560 K. These 2D exchange data provide strong evidence for diffusionlike motion of the modulation wave in BSN. Such motions in BSN had been previousl... | NMR; Hahn spin-echo decay; Incommensurate systems. | 2001 |

Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Detection of soliton shape modes in polyacetylene | We observed soliton shape modes by photoinduced absorption in partially isomerized (CH)x and (CD)x, coexisting with the soliton translational modes. The shape modes' ir activity, their dependence on the degree of isomerization, and the photoinduced spectra are explained in detail by a symmetry-break... | Soliton shape modes; Polyacetylene; Photoinduced absorption | 1986-12 |

Ailion, David Charles; Morris, Alan H. | Determination of lung water content and distribution by nuclear magnetic resonance imaging | NMR imaging techniques are applicable to the assessment of lung water content and distribution because the NMR signal is, under certain conditions, proportional to tissue proton density.

Rogachev, Andrey | Determination of the superconductor-insulator phase diagram for one-dimensional wires | We establish the superconductor-insulator phase diagram for quasi-one-dimensional wires by measuring a large set of MoGe nanowires. This diagram is roughly consistent with the Chakravarty-Schmid-Bulgadaev phase boundary, namely, with the critical resistance being equal to RQ ¼ h=4e2.
