studies using these new data, those ofGilbert et al.[1973],Jordan and Anderson[1974], andGilbert and Dziewonski[1975] are the most relevant, since these workers made an attempt to invert simultaneously the entire available seismic data set to model the deep structure of the earth's interior...
Earth compositionThe deep interior structure of the earth has been extensively analyzed using a wide variety of seismic phases and techniques during the last four years. Most studies have emphasized quantitative three-dimensional mapping of the lateral velocity heterogeneity of the mantle and core. ...
Due to the internal structure of the Earth, at certain dis- tances, e.g., around 20~ and 144~ concentration (focusing) of the energy of traveling seismic waves takes place. Seismic signals recorded close to these distances often show an increase of amplitude even with increasing distance ...

, we threshold {wij} and obtain the adjacency matrix, Aij = H(wij − W), where H is the Heaviside step-function and W is a threshold chosen such that each node is connected, on average, to 5% of the Earth surface (see the Supplementary Information, SI, for a discussion ...

GPS placed a quarter of them in their villages and most of the rest within 50 km of their villages. GPS’s accuracy and power to infer the biogeography of worldwide individuals down to their country or, in some cases, village, of origin, underscores the promise of admixture-based methods...
The cross-β sheet entity comprising an indefinitely repeating intermolecular β sheet motif is unique among protein folds. It grows by recruitment of the corresponding amyloid protein, while its repetitiveness can translate what would be a nonspecific activity as monomer into a potent one through ...
Although phages are the most abundant and diversified biological entity on earth, each phage can only infect a limited number of bacterial strains. This specific phage-host interaction is determined, in part, by the protein recognition device located at the tip of the phage tail, which engages ...
