Fourier Mass Lower Bounds for Batchelor‐Regime Passive Scalars

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT Batchelor predicted that a passive scalar ψν$\psi ^\nu$ with diffusivity ν$\nu$, advected by a smooth fluid velocity, should typically have Fourier mass distributed as |ψ̂ν|2(k)≈|k|−d$|\widehat{\psi }^\nu |^2(k) \approx |k|^{-d}$ for |k|≪ν−1/2$|k| \ll \nu ^{-1/2}$.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

Wildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Twenty years of dynamic occupancy models: a review of applications and look to the future

Ecography, EarlyView.
Since their introduction over 20 years ago, dynamic occupancy models (DOMs) have become a powerful and flexible framework for estimating species occupancy across space and time while accounting for imperfect detection. As their popularity has increased and extensions have further expanded their capabilities, DOMs have been applied to increasingly ...

Integrating wavelet transformation with Markov random field analysis for the depth estimation of light‐field images

IET Computer Vision, 2017
This study addresses the problem of recovering the three‐dimensional depth data from the images taken by a light‐field camera. Unlike the conventional approach to extract the depth information from the spatial and the angular gradients in the epipolar ...

The Effectiveness of Interventions Addressing Conspiracy Beliefs: A Meta‐Analysis

European Journal of Social Psychology, EarlyView.
ABSTRACT Reducing conspiracy beliefs through effective interventions may help mitigate potential harmful consequences, such as vaccine hesitancy and prejudice. Therefore, a systematic literature search was conducted in Web of Science, PsycINFO, and Google Scholar for experiments testing interventions that could potentially reduce conspiracy beliefs ...

Adaptive Self-Occlusion Behavior Recognition Based on pLSA

Journal of Applied Mathematics, 2013
Human action recognition is an important area of human action recognition research. Focusing on the problem of self-occlusion in the field of human action recognition, a new adaptive occlusion state behavior recognition approach was presented based on ...
