Mechanochemical-Triggered Confined Coordination of Iron-Biomass Composites for Efficient Cr(VI) Reduction Under Circumneutral pH Via Accelerated Electron Extraction.

Green and eco-friendly iron-based materials for efficient Cr(VI) removal have attracted considerable interest, but challenges related to narrow working pH ranges and iron utilization efficiency still remain. Herein, inspired by the hot-spot effect-triggered confined coordination strategy, a biomass-confined iron-based reductant (CMC-GTB/Fe) is designed for Cr(VI) reduction and detoxification. Electron enrichment and confinement on biomass carriers are achieved through electron transfer mediated by coordination interactions between anchored iron species and biomass.

Positive feedback loop between NRAS mutation and RAB27B expression in endothelial cells.

Recent findings implicate somatic NRAS mutation in human endothelial cells in the pathogenesis of vascular anomalies. Our previous study demonstrated that RAB27B, a small GTPase of the RAB family, regulates NRAS palmitoylation in leukemia cells and is essential for NRAS-mutant leukemia development. However, the role of RAB27B in NRAS mutant endothelial cells are still unknown.

By employing Sentinel-2's near-infrared, short-wave infrared, and green bands to calculate tristimulus values-replacing traditional RGB bands-MABI significantly enhances the distinction between algal blooms and water.

Study of Five-Hundred-Meter Aperture Spherical Telescope Feed Cabin Time-Series Prediction Studies Based on Long Short-Term Memory-Self-Attention.

The Five-hundred-meter Aperture Spherical Telescope (FAST), as the world's most sensitive single-dish radio telescope, necessitates highly accurate positioning of its feed cabin to utilize its full observational potential. Traditional positioning methods that rely on GNSS and IMU, integrated with TS devices, but the GNSS and TS devices are vulnerable to other signal and environmental disruptions, which can significantly diminish position accuracy and even cause observation to stop. To address these challenges, this study introduces a novel time-series prediction model that integrates Long Short-Term Memory (LSTM) networks with a Self-Attention mechanism.
