Mishchenko, Eugene | Resonant finite-size impurities in graphene, unitary limit, and Friedel oscillations | A unitary limit for model point scatterers in graphene is known to reveal low-energy resonances. The same limit could be achieved from hybridization of band electrons with the localized impurity level positioned in the vicinity of the Fermi level. The finite-size defects represent an easier realizat... | 2012-01-01 | |

Mitchell, Joyce A. | Retrieval from full-text medical literature: the dream & the reality | While the retrieval of the full-text of a document might seem to end all the hassle of using traditional retrieval systems, the results of the MEDLINE/Full-Text Project indicate that retrieval from the current full-text databases of biomedical journal literature does not match the dream. During the ... | 1991-01-01 | |

Adler, Frederick R. | Reply: | We appreciate the comments of Drs. Craig and Simpson and Drs. Mullins and Schwartz, and the challenge they raise to make MALD more believable, comprehensible, and usable. Acetaminophen (APAP) toxicity is indeed a complex process involving multiple steps. Although the underlying mathematics is more i... | 2012-01-01 | |

Light, Alan R. | Response to Letter by Dr. Smirmaul Group III/IV muscle afferents contribute to both perception of effort and fatigue | We thank Dr. Smirmaul for his interest in our findings, but advise caution not to over-interpret the data to address a question which would have required an entirely different study design. Specifically, the letter to the editor is strongly focused on effort perception, a variable which was, as expe... | 2014-01-01 | |

Armentrout, Peter B. | The simplest b2+ ion: determining its structure from its energetics by a direct comparison of the threshold collision-induced dissociation of protonated oxazolone and diketopiperazine | Energy-resolved collision-induced dissociation of b2 + ions derived from protonated GGG and GAG are compared with that of protonated diketopiperazine (H+DKP). Absolute dissociation cross sections are obtained using a guided ion beam tandem mass spectrometer and analyzed using statistical methods. Th... | 2012-01-01 | |

Codding, Brian | Shellfishing and the colonization of sahul: a multivariate model evaluating the dynamic effects of prey utility, transport considerations and life-history on foraging patterns and midden composition | Archaeological evidence of shellfish exploitation along the coast of Sahul (Pleistocene Australia-New Guinea) points to an apparent paradox. While the continental record as a whole suggests that human populations were very low from initial colonization through early Holocene, coastal and peri-c... | 2014-01-01 | |

Gondolo, Paolo | Simple renormalizable flavor symmetry for neutrino oscillations | The recent measurement of a nonzero neutrino mixing angle θ13 requires a modification of the tri-bimaximal mixing pattern that predicts a zero value for it. We propose a new neutrino mixing pattern based on a spontaneously broken A4 flavor symmetry and a type-I seesaw mechanism. Our model allows fo... | 2012-01-01 | |

Bernstein, Paul S. | Skin carotenoid status measured by resonance Raman spectroscopy as a biomarker of fruit and vegetable intake in preschool children | Background/Objective: Dietary assessment in children is difficult, suggesting a need to develop more objective biomarkers of intake. Resonance Raman spectroscopy (RRS) is a noninvasive, validated method of measuring carotenoid status in skin as a biomarker of fruit/vegetable intake. The purpose of t... | 2012-01-01 | |

Tiwari, Ashutosh | Shape of the Hanle curve in spin-transport structures in the presence of an ac drive | Resistance between two ferromagnetic electrodes coupled to a normal channel depends on their relative magnetizations. The spin-dependent component, R, of the resistance changes with magnetic field, B, normal to the directions of magnetizations. In the field of spin transport, this change, R(B), orig... | 2014-01-01 | |

Wen, Ming | Sex and ethnic differences in validity of self-reported adult height, weight and body mass index | Objectives: Describe self-reported and mea-sured height, weight, and body mass index (BMI) stratified by sex and ethnicity in the United States, explore ethnic variations in the likelihood of under-reporting BMI, and investigate pathways linking race/ethnicity to the underassessment of BMI. | 2012-01-01 | |

Freire, Juliana | Siphoning hidden-web data through keyword-based interfaces | In this paper, we study the problem of automating the retrieval of data hidden behind simple search interfaces that accept keyword-based queries. Our goal is to automatically retrieve all available results (or, as many as possible). We propose a new approach to siphon hidden data that automatically ... | 2004-01-01 | |

Stringfellow, Gerald B. | Simulation of self-assembled compositional core-shell structures in In xGa 1-xN nanowires | We report the simulation of compositional core-shell structure formation in epitaxial InGaN nanowires (NWs) and its dependence on kinetic growth mode and epitaxial relation to substrate, based on atomistic-strain-model Monte Carlo simulations. On a lattice mismatched substrate, the layer-by-layer gr... | 2012-01-01 | |

Regehr, John | Using hierarchical scheduling to support soft real-time applications in general-purpose operating systems | The CPU schedulers in general-purpose operating systems are designed to provide fast response time for interactive applications and high throughput for batch applications. The heuristics used to achieve these goals do not lend themselves to scheduling real-time applications, nor do they meet other s... | 2001-01-01 | |
