Cerium isotopic behavior during gabbro weathering in a tropical climate

Cerium (Ce) is a redox-sensitive element, making it an effective tracer for continental weathering processes. To elucidate mechanisms of Ce isotopic fractionation during chemical weathering processes, we analyzed Ce isotopic compositions across a well-developed latosol profile de...

CGRD: An Exemplar-Free Extension of Knowledge Distillation for Class-Incremental 3D Point Cloud Semantic Segmentation

Class-incremental three-dimensional point cloud semantic segmentation requires models to learn newly introduced categories while preserving previously acquired knowledge without storing historical point clouds. This setting is challenged by representation drift during incremental...

Simulation verification of adaptive dead time control for radiation detectors based on reinforcement learning and FPGA

Abstract Addressing the critical engineering challenge of severe data loss caused by system dead time in dynamic high-flux scenarios within radiation monitoring environments, this paper proposes an adaptive dead-time control system based on circuit-algorithm-hardware co-design. T...

Monte Carlo-Based Borehole Effect Correction in Uranium Fission Prompt Neutron Logging Using the Epithermal-to-Thermal Neutron Ratio

Borehole effects are a critical source of uncertainty in uranium fission prompt neutron (PFN) logging, particularly in sandstone-type uranium deposits with complex borehole conditions. This study develops a quantitative correction method for borehole diameter effects based on Mon...

Surface-modified ZnO nanowire arrays ultraviolet photodetector with Cu nanoparticles for enhanced detection performance

The state-of-the-art ultraviolet photodetectors (UV PDs) have been extensively used in environmental monitoring, security checks, and optical communication. The conventional ZnO UV PDs often exhibit low sensitivity and slow response/decay speed. In this study, Cu nanoparticles (N...

Removal of Residual Ammonium from Weathered Crust Elution-Deposited Rare Earth Ore Tailings by Magnesium Chloride: Kinetics and Mass Transfer

After in situ leaching of weathered crust elution-deposited rare earth ore (WREO), large amounts of residual ammonium (RA) salts remain in the ore body and slowly release, causing persistent ammonia-nitrogen pollution in surrounding waters. This study proposes using magnesium chl...

Smart Urban Agriculture in Transition: A Systematic Review of ICT Integration, Applications, and Challenges

This paper systematically reviews the emerging field of smart urban agriculture, defined as the integration of information and communication technologies (ICTs) into food production practices within and around built-up urban areas. Although urban agriculture and digital agricultu...
