It is widely accepted that plate divergence at mid-ocean ridges drives mantle flow, mantle melting, and the formation of new oceanic crust. However, many of the details of this process remain obscure because of the inaccessibility of the mantle to direct observation. Thus, geodynamic models are needed to provide insight...
In this paper we outline a procedure we use for routine moment-tensor analysis of regional data from broadband seismic stations in northwestern North America and apply it to the moment magnitude 5.5, March, 1993, Scotts Mills, Oregon, earthquake. The results compare favorably with those obtained from teleseismic data. We found...
Recent evidence has demonstrated the importance of kidney function in healthy aging. We examined the association between kidney function and change in cognitive function in 3,907 participants in the Cardiovascular Health Study, recruited from 4 U.S. communities, and studied from 1992 - 1999. Kidney function was measured by cystatin C-based...
BACKGROUND: Whether limitation in ability to perform activities of daily living (ADL) or gait speed can identify subgroups of elders in whom the association of systolic (SBP) and diastolic (DBP) blood pressure with cardiovascular events and death differs is not well established.
METHODS: We evaluated whether ADL and gait speed...
Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...
Cyprinid herpesvirus 3 (CyHV-3), commonly known as koi herpesvirus (KHV), is a member of the Alloherpesviridae, and is a recently discovered emerging herpesvirus that is highly pathogenic for koi and common carp. Our previous study demonstrated that CyHV-3 becomes latent in peripheral white blood cells (WBC). In this study, CyHV-3...
Climate change and efforts to address it have put the electric utility system under increasing pressure to adapt and evolve. Key to the success of these efforts will be the support of public utility commissions, the state agencies that oversee retail electric utilities. In an effort to determine how these...
Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures
that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how
silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...

Objectives:
To examine the association between kidney function and all-cause mortality in octogenarians.
Design
Retrospective analysis of prospectively collected data.
Setting:
Community.
Participants:
Serum creatinine and cystatin C were measured in 1,053 Cardiovascular Health Study (CHS) All Stars participants.
Measurements:
Estimated glomerular filtration rate (eGFR) was determined using the Chronic...
