A semi-parametric approach to estimate risk functions associated with multi-dimensional exposure profiles: application to smoking and lung cancer [PDF]

open access: yes, 2013
A common characteristic of environmental epidemiology is the multi-dimensional aspect of exposure patterns, frequently reduced to a cumulative exposure for simplicity of analysis.

Long-term trends in the ambient PM2.5- and O3-related mortality burdens in the United States under emission reductions from 1990 to 2010 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Concentrations of both fine particulate matter (PM2.5) and ozone (O3) in the United States (US) have decreased significantly since 1990, mainly because of air quality regulations.

Environmental effects on magnetic fluorescent powder development of fingermarks on bird of prey feathers [PDF]

open access: yes, 2019
A comparison study of the effects of environmental conditions on the development of latent fingermarks on raptor feathers using green magnetic fluorescent powder was undertaken using both sebaceous loaded and natural fingermark deposits.

A simple lightning assimilation technique for improving retrospective WRF simulations

open access: yesJournal of Advances in Modeling Earth Systems, 2016
Convective rainfall is often a large source of error in retrospective modeling applications. In particular, positive rainfall biases commonly exist during summer months due to overactive convective parameterizations. In this study, lightning assimilation

Distribution and Causes of Global Forest Fragmentation

open access: yesEcology and Society, 2003
Because human land uses tend to expand over time, forests that share a high proportion of their borders with anthropogenic uses are at higher risk of further degradation than forests that share a high proportion of their borders with non-forest, natural ...
