Winter Bird Diversity and Abundance in Small Farmlands in a Megacity of Southern China

open access: yesFrontiers in Ecology and Evolution, 2022
Urban expansion often accompanies a loss of natural habitats and arable lands but an increase in urban population. In China, vegetable-dominant small farmlands are common in urban/peri-urban areas.

NanoMagnetic Logic Microprocessor Hierarchical Power Model [PDF]

open access: yes, 2012
The interest on emerging nanotechnologies has been recently focused on NanoMagnetic Logic (NML), which has unique appealing features. NML circuits have a very low power consumption and, due to their magnetic nature, they maintain the information safely ...

Dynamic Hierarchical Models

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1993
SUMMARY An analysis of a time series of cross-sectional data is considered under a Bayesian perspective. Information is modelled in terms of prior distributions and stratified parametric linear models developed by Lindley and Smith and dynamic linear models developed by Harrison and Stevens are merged into a general framework.

Western bumble bee: declines in the continental United States and range‐wide information gaps

open access: yesEcosphere, 2020
In recent decades, many bumble bee species have declined due to changes in habitat, climate, and pressures from pathogens, pesticides, and introduced species.

Modelling hierarchical flocking

open access: yesNew Journal of Physics, 2019
Abstract We present a general framework for modeling a wide selection of flocking scenarios under free boundary conditions. Several variants have been considered—including examples for the widely observed behavior of hierarchically interacting units. The models we have simulated correspond to classes of various realistic situations.

Multi-Leader Multi-Follower Model with Aggregative Uncertainty

open access: yesGames, 2017
We study a non-cooperative game with aggregative structure, namely when the payoffs depend on the strategies of the opponent players through an aggregator function. We assume that a subset of players behave as leaders in a Stackelberg model. The leaders,

Towards Human Activity Recognition: A Hierarchical Feature Selection Framework

open access: yesSensors, 2018
The inherent complexity of human physical activities makes it difficult to accurately recognize activities with wearable sensors. To this end, this paper proposes a hierarchical activity recognition framework and two different feature selection methods ...

Metacognitive Ability and the Precision of Confidence

open access: yesFrontiers in Human Neuroscience, 2022
In prior research, signal detection theory (SDT) has been widely utilized to assess metacognitive ability. However, the SDT metacognitive model requires the use of a two-alternative forced-choice task, while confidence must also be measured discretely ...

Model-Checking Hierarchical Structures [PDF]

open access: yes20th Annual IEEE Symposium on Logic in Computer Science (LICS' 05), 2006
Hierarchical graph definitions allow a modular description of graphs using modules for the specification of repeated substructures. Beside this modularity, hierarchical graph definitions also allow to specify graphs of exponential size using polynomial size descriptions.
