Land use planning: A potential force for retaining habitat connectivity in the Greater Yellowstone Ecosystem and Beyond

The grizzly bear (Ursus arctos horribilis) population in the Greater Yellowstone Ecosystem (GYE) is perceived to have been isolated from the population in the Northern Continental Divide Ecosystem for a century.Better land use planning is needed to thwart progressive intra- and inter-ecosystem habitat fragmentation, especially due to private land d

An improved performance of greedy heuristic solutions for a bi-criteria mixture packaging problem of two types of items with bounded weights

In this paper, we treat a lexicographic bi-criteria combinatorial optimization model of mixture packaging of two types of items, which arises in actual food packing systems, so-called multi-head weighers.The primary objective is to minimize the total weight of chosen items for a package, and the second objective is to maximize the Toy Airplanes tot

The Impact of Precipitation Deficit and Urbanization on Variations in Water Storage in the Beijing-Tianjin-Hebei Urban Agglomeration

Depletion of water resources has threatened water security in the Beijing-Tianjin-Hebei urban agglomeration, China.However, the relative importance of precipitation and urbanization to water storage change has not been sufficiently studied.In this study, both terrestrial water storage (TWS) and groundwater storage (GWS) change in Jing-Jin-Ji from 1
