Ecological Network Characteristics of Cultivated Land Carbon Flows in Major Grain‐Producing Regions: Case Study of Jingzhou City, China

Land Degradation &Development, EarlyView.
ABSTRACT Land‐use changes related to cultivated land significantly affect the regional carbon budget in major grain‐producing regions, yet the ecological network characteristics of cultivated land carbon flows remain insufficiently understood. This study developed an integrated framework that combined ecological network analysis with spatial analysis ...

Future Soil Erosion Under Combined CMIP6 Climate Projections and Land Use/Land Cover Change: A RUSLE‐Based Assessment of the Kampe Omi Dam Basin in Nigeria

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major environmental challenge in Nigeria, driven by the combined effects of climate variability and land use/land cover (LULC) changes. Understanding future dynamics is essential for effective soil conservation planning.

Quartz Electron Spin Resonance (ESR) Dating of River Terraces in the Zhenjiang River of the Upper Beijiang River

Redai dili
River terraces are important geomorphic indicators that reveal the evolution of rivers, and their climatic and tectonic responses. Dating is key to studying terrace evolution.

Revisiting Inductively Coupled Wireless Coils in MRI: Mitigating Over‐Coupling With Preamplifiers

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Inductively coupled coils enhance local MRI sensitivity, yet strong coupling with nearby primary coils typically causes resonance splitting and impedance mismatch, which are traditionally considered detrimental. This work investigates why inductively coupled coils can still function effectively even in the presence of severe coupling ...

River Terraces along the Upper Mabechi River

Annals of The Tohoku Geographycal Asocciation, 1987
Formation of river terraces along the upper Mabechi River in northeast Japan is investigated tephrochronologically and its relation to piedmont gentle slope is discussed.Four terraces, that is, the Higher Terrace, Terrace I, Terrace II and Terrace III, are recognized in the study area.

Zooarchaeology of Houses and Middens: Investigating Patterns of Assemblage Composition at Early Inuit Sites Across the North American Arctic

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study examines faunal assemblages from paired semisubterranean houses and middens at 10 Early Inuit sites spanning the North American Arctic (ca. 1200–1500 ce) to evaluate whether local resource bases or other factors primarily structure zooarchaeological variability.

Geomorphometric analysis of urban fluvial terraces using UAV LiDAR: A case study from the La Silla River, Mexico [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This study presents a high-resolution geomorphological analysis of river terraces along the urban corridor of the La Silla River (Monterrey Metropolitan Area, Mexico) using UAV-based LiDAR and photogrammetry, with a DJI Matrice 350 RTK equipped with a ...

Where were all the trees? Computer vision meets landscape history to unlock the potential of historical Ordnance Survey maps

People and Nature, EarlyView.
Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
