Spatiotemporal evolution and multi-scenario simulation of the land-use cover change and habitat quality in arid and semi-arid areas: a case study of the urban agglomeration along t...
Published 2025-08-01“…Habitat quality (HQ) is recognized as a significant factor in biodiversity maintenance and ecological conservation advancement, and the land-use cover change (LUCC) can directly affect the spatial pattern and evolution of HQ. Land-use datasets spanning 2010, 2015, and 2020 were analyzed through the integrated application of the future land-use simulation (FLUS) model and the integrated valuation of ecosystem services and trade-offs (InVEST) model, supplemented by multiple analytical indicators, resulting in LUCC patterns and HQ variations being investigated within the urban agglomeration along the Yellow River in Ningxia, China. …”

Spin–orbit coupling induced by ascorbic acid crystals
Published 2023-01-01“…We experimentally demonstrate these effects using samples of crystallized ascorbic acid and observing the creation of optical vortices in transmitted laser beams, as well as the formation of inhomogeneous polarisation patterns. Our findings suggest the use of some spherulites based on other materials in frequency ranges, e.g. in the THz domain, where polarisation and spatial shaping of electromagnetic radiation is still a challenging task.…”

A Sharpe ratio-integrated indicator system for land use changes ecological risks: Within coupled disaster-economic assessment frameworks
Published 2025-07-01“…The Sharpe ratio effectively couples these parameters for risk assessment. (2) Under three scenarios – natural development, urban expansion, and ecological conservation – the mean ERI values were 0.4718, 0.4719, and 0.4703 respectively, indicating highest overall risk in urban expansion. (3) Spatial analysis revealed similar risk gradation patterns across the plain, dominated by medium–high risk areas (20.33%), followed by medium-risk (30.21%), with relatively smaller proportions of high-risk (13.77%) and medium–low risk (14.23%) zones.
