Summary: Distributed fiber-optical acoustic sensing (DAS) is a promising technology in seismic exploration, but the quality of DAS-VSP data is often affected by random and coherent noises. To improve the signal-to-noise ratio, a CNN model based on L-FM-CNN is proposed, utilizing leaky ReLU as the activation function. By constructing a high-authenticity theoretical seismic data set and using a new loss function ERM, the proposed method proves effective in denoising DAS-VSP data with different SNRs.

Summary: The article proposes a deeply supervised attention metric-based network (DSAMNet) to address the challenges in change detection. The network uses a metric module for deep metric learning, integrated with convolutional block attention modules (CBAM), and a DS module to enhance feature extraction and generate more useful features. A new CD dataset, Sun Yat-Sen University (SYSU)-CD, containing 20,000 aerial image pairs, is also created for bitemporal image CD. Experimental results show that the network achieves the highest accuracy on both datasets.

Summary: This study presents a new method to estimate ground-level ozone concentrations in China using solar radiation intensity and surface temperature. The generated dataset provides reliable and valuable information, including short-term severe ozone pollution events and the rapid increase and recovery of ozone concentrations associated with changes in anthropogenic emissions. The study also reveals an increase in summertime ozone concentrations and the probability of daily ozone pollution since 2015, with a decline observed in 2020 due to air pollution control measures and the COVID-19 pandemic.

Summary: With the rapid development of deep learning, many deep learning-based approaches have achieved great success in object detection tasks. However, existing datasets have limitations in terms of scale, category, and image. To address the needs of high-resolution remote sensing images, we propose a novel benchmark dataset called FAIR1M, which includes over 1 million instances and more than 40,000 images for fine-grained object recognition. The FAIR1M dataset has several unique characteristics, such as being larger than other datasets, providing richer category information, containing geographic information, and having better image quality. We evaluate state-of-the-art methods on the FAIR1M dataset and propose improvements to the evaluation metrics and the incorporation of hierarchy detection. We believe that the FAIR1M dataset will contribute to the field of earth observation through fine-grained object detection in large-scale real-world scenes.
