Recommender systems are important building blocks in many of today's e-commerce applications including targeted advertising, personalized marketing and information retrieval. In recent years, the importance of contextual information has motivated many researchers to focus on designing systems that produce personalized recommendations in accordance with the(More)
[1] Based on 1–2 years of continuous observations of seismic ambient noise data obtained at more than 600 stations in and around Tibet, Rayleigh wave phase velocity maps are constructed from 10 s to 60 s period. A 3-D Vsv model of the crust and uppermost mantle is derived from these maps. The 3-D model exhibits significant apparently interconnected low(More)
[1] Ambient noise tomography is applied to the significant data resources now available across Tibet and surrounding regions to produce Rayleigh wave phase speed maps at periods between 6 and 50 s. Data resources include the permanent Federation of Digital Seismographic Networks, five temporary U. paths. With such a heterogeneous data set, data quality(More)
Research in context-aware recommender systems (CARS) usually requires the identification of the influential contextual variables in advance. In collaborative recommendation, there is a substantial trade-off between applying context very strictly and achieving good coverage and accuracy. Our prior work showed that this tradeoff can be managed by applying the(More)
[1] A 3‐D shear velocity model of the crust and uppermost mantle to a depth of 100 km is presented beneath the North China Craton (NCC), northeastern China, the Korean Peninsula, and the Sea of Japan. Ambient noise Rayleigh wave tomography is applied to data from more than 300 broadband seismic stations from Chinese provincial networks (CEArray), the(More)
Two years of continuous recordings of ambient seismic noise observed at 354 stations in South China from 2009 to 2010 are used to estimate Rayleigh wave group and phase velocity maps from 6 to 40 s period. These results are merged with Rayleigh wave phase velocity maps from 25 to 70 s period derived from earthquakes in the same time frame. Eikonal(More)
12 Phase velocities across eastern Tibet and surrounding regions are mapped using Rayleigh 13 (8-65 sec) and Love (8-44 sec) wave ambient noise tomography based on data from more 14 than 400 PASSCAL and CEArray stations. A Bayesian Monte-Carlo inversion method is 15 applied to generate 3-D distributions of Vsh and Vsv in the crust and uppermost mantle 16(More)
We apply ambient noise tomography to significant seismic data resources in a region including the northeastern Tibetan plateau, the Ordos block and the Sichuan basin. The seismic data come from about 160 stations of the provincial broadband digital seismograph networks of China. Ambient noise cross-correlations are performed on the data recorded between(More)
When individuals' actions are incongruent with those of the group they belong to, they may change their initial behavior in order to conform to the group norm. This phenomenon is known as "social conformity." In the present study, we used event-related functional magnetic resonance imaging (fMRI) to investigate brain activity in response to group opinion(More)
Distinctions are commonly made regarding preferences for insertive or receptive anal intercourse within gay male communities. Three sexual self-labels are typically specified: "top," meaning a man who prefers the insertive role, "bottom," meaning a man who prefers the receptive role, and "versatile," meaning a man willing to perform either role. In this(More)
