Particle Transport Acceleration with ‘Consistent’ Eddington Factors
We have developed a new Generalized Quasidiffusion (GQD) method to accelerate the iterative convergence of SN particle transport problems. The standard Quasidiffusion (QD) or Variable Eddington Factor (VEF) method converges rapidly but is inconsis...

Nonclassical Particle Transport
In classical particle transport, the probability that a particle interacts with the background medium is proportional to the path length traveled by that particle, and the proportionality constant depends on the density of the medium and on the pa...

Neural Networks for Unfolding Neutron Energy Spectra
Acquiring accurate neutron energy spectrum information is of vital importance to national security as well as personal safety. Unfolding neutron energy spectra from detector responses is a heavily researched area due to the importance of neutron e...

Unraveling historical evolution of the human-attitude towards red fox in Finland.
Summary of the study
Human attitudes towards urban wildlife are often positive, but this was not the case just a few decades ago, as exemplified by urban red foxes (Vulpes vulpes) in Finland. Mostly appreciated by townsfolk today, they were consi...

Introduced plants of <i>Lupinus polyphyllus</i> are larger but flower less frequently than conspecifics from the native range: Results of the first year
Abstract
Abstract Introduced species, which establish in novel environments, provide an opportunity to explore trait evolution and how it may contribute to the distribution and spread of species. Here, we explore trait changes of the perennial h...

Strong gene flow explains lack of mating system variation in the perennial herb, <i>Vincetoxicum hirundinaria</i> , in a fragmented landscape
Abstract
among relatives. The overall low inbreeding coefficients indicate that even in small populations mating among relatives is rare. High allelic richness of both maternal and offspring genotypes as well as limited genetic differentiation a...
