Southern flying squirrel use of forests managed for red‐cockaded woodpeckers in East‐Central Mississippi 密西西比中东部红顶啄木鸟繁殖林中的南方鼯鼠栖息地利用

open access: yesWildlife Letters, Volume 2, Issue 3, Page 131-139, September 2024.
Southern flying squirrels (flying squirrel; Glaucomys volans) frequently displace endangered red‐cockaded woodpeckers (RCW; Dryobates borealis) within forest partitions managed specifically for RCW cavities (“cluster partitions”). We found little to no evidence of differences in home range size and composition between flying squirrels within or outside

Operation Scheduling of Distribution Network with Photovoltaic/Wind/Battery Multi‐Microgrids and Reconfiguration considering Reliability and Self‐Healing

open access: yesInternational Journal of Energy Research, Volume 2024, Issue 1, 2024.
In this paper, a new simultaneous framework of distribution network operation is proposed based on the scheduling of photovoltaic/wind/battery multi‐microgrids with network reconfiguration considering self‐healing. The objective function is considered to minimize the energy losses, and multi‐microgrids cost and improve the reliability indices including
