Solomon, Douglas Kip | Evaluating the use of strontium isotopes in tree rings to record the isotopic signal of dust deposited on the Wasatch Mountains | Dust cycling from the Great Basin to the Rocky Mountains is an important component of ecological and hydrological processes. We investigated the use of strontium (Sr) concentrations and isotope ratios (87Sr/86Sr) in tree rings as a proxy for dust deposition. We report Sr concentrations and isotope r... | 2014-01-01 | |

Riloff, Ellen M. | Learning and evaluating the content and structure of a term taxonomy | In this paper, we describe a weakly supervised bootstrapping algorithm that reads Web texts and learns taxonomy terms. The bootstrapping algorithm starts with two seed words (a seed hypernym (Root concept) and a seed hyponym) that are inserted into a doubly anchored hyponym pattern. In alternatin... | Weakly supervised; Bootstrapping algorithm; Seed hypernym; Seed hyponym; Root concept; Term taxonomy; Learning by reading systems | 2009 |

Gesteland, Raymond F.; Atkins, John F.; Felden, Brice; McCutcheon, John P. | Probing the structure of the Escherichia coli 10Sa RNA (tmRNA) | The conformation of the Escherichia coli 10Sa RNA (tmRNA) in solution was investigated using chemical and enzymatic probes. Single- and double-stranded domains were identified by hydrolysis of tmRNA in imidazole buffer and by lead(II)-induced cleavages. Ribonucleases T1 and S1 were used to map unpai... | Covariation; Pseudoknot; Structural Probing; 10Sa RNA; tmRNA | 1997 |

Reichler, Thomas J.; Kim, Junsu | Uncertainties in the climate mean state of global observations, reanalyses, and the GFDL climate model | Climate research relies on realistic atmospheric data over long periods of time. Global reanalyses or observations are commonly used for this type of work. However, the many problems associated with both the reanalyses and observations cast doubts on the reliability of such data for climate appli... | Climate; Atmospheric data; Reanalyses | 2008 |
