Dynamics of populations with nonoverlapping generations, continuous mortality, and discrete reproductive periods
(Elsevier, 1994-08)
Simple nonlinear difference equations have been used to describe the growth of populations with nonoverlapping generations; these equations assume mortality and recruitment to be discrete and instantaneous. In reality, ...
Development of Bayesian Monte Carlo techniques for water quality model uncertainty
(Elsevier, 1992-07)
A new technique, Bayesian Monte Carlo (BMC), is used to quantify errors in water quality models caused by uncertain parameters. BMC also provides estimates of parameter uncertainty as a function of observed data on model ...
Improving exposure assessment in environmental epidemiology: Application of spatio-temporal visualization tools
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2005-05)
A thorough assessment of human exposure to environmental agents should incorporate mobility patterns and temporal changes in human behaviors and concentrations of contaminants; yet the temporal dimension is often ...
Exposure to strong static magnetic field slows the growth of human cancer cells in vitro
(Wiley Subscription Services, Inc., A Wiley Company, 1996)
Proposals to enhance the amount of radiation dose delivered to small tumors with radioimmunotherapy by constraining emitted electrons with very strong homogeneous static magnetic fields has renewed interest in the cellular ...
Discipline‐centered post‐secondary science education research: Understanding university level science learning
(Carnegie Foundation for the Advancement of TeachingWiley Periodicals, Inc., 2013-08)
Comment on “Effects of 60 Hz electromagnetic fields on early growth in three plant species and a replication of previous results” by Mark S. Davies
(Wiley Subscription Services, Inc., A Wiley Company, 1997)
No abstract.
Thermodynamic modelling of bio-species accommodation
(Elsevier, 1978-01)
An ecological model has been constructed. A chemical analogy to the biological system has been developed, and the system's driving forces have been identified.
Mapping freeze/thaw boundaries with SMMR data
(Elsevier, 1990-08)
Nimbus 7 SMMR data are used to map daily freeze/thaw patterns in the upper Midwest for the fall of 1984. The combination of a low 37 GHz radiobrightness and a negative 10.7, 18 and 37 GHz spectral gradient, [part]Tb/[part]f, ...
Symbolic Intersect Detection: A Method for Improving Spatial Intersect Joins
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-06)
Due to the increasing popularity of spatial databases, researchers have focused their efforts on improving the query processing performance of the most expensive spatial database operation: the spatial join. While most ...
Impulse response analysis in vector autoregressions with unknown lag order
(John Wiley & Sons, Ltd., 2001-04)
We show that the effects of overfitting and underfitting a vector autoregressive (VAR) model are strongly asymmetric for VAR summary statistics involving higher-order dynamics (such as impulse response functions, variance ...
