Multi-Channel Sampling on Graphs and Its Relationship to Graph Filter Banks

open access: yesIEEE Open Journal of Signal Processing, 2023
In this article, we consider multi-channel sampling (MCS) for graph signals. We generally encounter full-band graph signals beyond the bandlimited ones in many applications, such as piecewise constant/smooth graph signals and union of bandlimited graph ...

Brain oscillations in reflecting motor status and recovery induced by action observation-driven robotic hand intervention in chronic stroke

open access: yesFrontiers in Neuroscience, 2023
Hand rehabilitation in chronic stroke remains challenging, and finding markers that could reflect motor function would help to understand and evaluate the therapy and recovery.

Band Wear and Effects on Recovery and Survival Estimates of Diving Ducks

open access: yesWildlife Society Bulletin, 2020
Wildlife biologists commonly use marked individuals to estimate population size and vital rates. If markers are lost or become too illegible to be reported (which we define as functional loss), population size and vital rates derived from marked ...

Decreased resting-state alpha-band activation and functional connectivity after sleep deprivation

open access: yesScientific Reports, 2021
Cognitive abilities are impaired by sleep deprivation and can be recovered when sufficient sleep is obtained. Changes in alpha-band oscillations are considered to be closely related to sleep deprivation. In this study, power spectrum, source localization

Does species composition of arctic geese recovered in prairie Canada vary by hunter residency?

open access: yesWildlife Society Bulletin, 2011
Estimates of goose harvest by the National Harvest Survey (NHS) in Canada are based on the assumption that species composition of harvest by non‐Canadians that hunt in Canada is equivalent to that of Canadians.

Canada Goose populations harvested in Eastern James Bay by Eeyou Istchee Cree hunters

open access: yesAvian Conservation and Ecology, 2022
Canada Geese (Branta canadensis) are an important wildlife food resource for Cree people living in communities along the James Bay coasts. According to Traditional Ecological Knowledge, environmental changes along the coast have affected hunting success.

Variations in band reporting rate and implications for kill rate in Greater Snow Geese

open access: yesAvian Conservation and Ecology, 2014
We assessed spatial and temporal variation in reporting probability of banded Greater Snow Geese (Chen caerulescens atlantica) shot by hunters in eastern North America and evaluated potential residual biases in kill rate estimation.

Study on Method and Mechanism of Noble Metals Photoelectric Deposition by Directly Utilizing Solar Energy

open access: yesAdvanced Energy & Sustainability Research, 2023
The recovery of noble metals is crucial in terms of resource utilization and ecological environment. Herein, a green strategy for the recovery of three noble metals, Au, Ag, and Pt, by photoelectric deposition at the cathode without external voltage is ...

Demographic consequences of translocation of overabundant Canada geese breeding in urban areas

open access: yesWildlife Society Bulletin, 2017
Translocation is a common tool for managing nuisance Canada geese (Branta canadensis) in urban areas across North America. However, no previous research has assessed how translocation affects survival and philopatry at donor and release sites.

The very low-frequency band of heart rate variability represents the slow recovery component after a mental stress task.

open access: yesPLoS ONE, 2017
The very low-frequency (VLF) band of heart rate variability (HRV) has different characteristics compared with other HRV components. Here we investigated differences in HRV changes after a mental stress task.
