Action recognition based on 3D heatmap volumes has received increasing attention recently because it is suitable for application to 3D CNNs to improve the recognition performance of deep networks. However, it is difficult for models to capture global dependencies due to their restricted receptive field. To effectively capture long-range dependencies and balance computations, a novel model, PoseTransformer3D with Global Cross Blocks (GCBs), is proposed for pose-based action recognition.

  • Short-term rainfall prediction is vital for safety and property protection, especially during heavy rainfall events; however, current models struggle with accuracy due to memory and positional issues.
  • The study introduces trajPredRNN+, a new model that combines trajectory segmentation and PredRNN, which employs attention mechanisms to better focus on imminent heavy rainfall predictions and includes a residual network for training stability.
  • Validation through experiments with radar echo data from the Shenzhen Meteorological Bureau shows that trajPredRNN+ significantly outperforms existing models in key performance metrics.

Article Synopsis
  • - The study aimed to simplify the Symptom Checklist-90 (SCL-90) by reducing its dimensions and item count, using machine learning techniques to maintain its effectiveness and practicality across various settings.
  • - By employing the Support Vector Classification (SVC) algorithm, researchers managed to condense the original ten dimensions to four and cut the item count from 90 to 29, achieving a high accuracy of 89.50% and individual dimension accuracies over 90%.
  • - The streamlined SCL-90 significantly reduced assessment time by 67.78% while maintaining a strong reliability coefficient of 0.95 and did not compromise the effectiveness of psychological assessments.

A multi-objective optimized OLSR routing protocol.

PLoS One

April 2024

School of Artificial Intelligence, Dongguan City University, Dongguan, China.

The rapid development of mobile communication devices has brought challenges to wireless networks, where data packets are able to organize and maintain local area networks more freely without the constraints of wired devices. Scholars have developed diverse network protocols on how to ensure data transmission while maintaining its self-organizational nature. However, it is difficult for traditional network protocols to meet the needs of increasingly complex networks.

Article Synopsis
  • A study investigates the effectiveness of using palygorskite to adsorb heavy metals from water-extracted solutions of municipal solid waste incineration fly ash, targeting pollution reduction from recycling efforts.
  • The research found that adding 3g of palygorskite to 100mL of the extracted solution removed over 99% of harmful metals like Pb, Cd, Cr, Cu, and Zn while still retaining the effectiveness of water-soluble chloride removal.
  • Comilling the palygorskite-adsorbed heavy metals with the fly ash resulted in stable binding of these metals, ensuring environmental safety by meeting regulatory standards and minimizing the risk of secondary pollution.
