Summary: Synthetic aperture radar (SAR) ship detection is widely used in various applications, but existing lightweight algorithms have problems such as misjudgment of targets mixed with the background and poor detection performance for targets with few samples. To address these issues, this paper proposes a detection network based on a multiscale feature pyramid network (FPN) that enhances target features, suppresses interference from the background, and reduces misjudgment. Experimental results show that the proposed network outperforms existing algorithms on public datasets.

Summary: Remote sensing ship recognition has wide applications in civil and military fields. However, the lack of public datasets for fine-grained ship recognition has restricted the progress in this area. In this paper, we propose an efficient information reuse network (EIRNet) and establish a public dataset for oriented ship recognition (DOSR). Our approach addresses the challenges of complex scenes and ship characteristics by using a dense feature fusion network and a dual-mask attention module. Experimental results show that our method achieves state-of-the-art performance on DOSR and another popular dataset (HRSC2016).

Summary: This study examined the response of different vegetation types in China's north-south transition zone to diurnal temperature changes. The results showed that daytime temperature increased at a rate 1.2 times that of nighttime temperature, and the effects of temperature changes varied among different vegetation types. Daytime warming promoted the growth of grasses, shrubs, deciduous broad-leaved forests, crops, and conifers, while nighttime warming had a positive effect only on the growth of evergreen broad-leaved forests.

Summary: Coastal slope is a crucial factor in understanding hydrodynamic and morphological processes, estimating extreme water levels, coastline erosion, and coastal vulnerability. However, accurate estimation of coastal slopes is limited, especially in sparsely populated and remote areas. This study demonstrates the potential of ICESat-2 measurements to estimate coastal slope, with promising results obtained in Texas, USA. The improved accuracy of ICESat-2 derived coastal slopes compared to current large-scale slopes derived from other sources suggests the method's applicability at a global scale.

Summary: This article assesses and verifies the influence of adversarial attacks on aerial image semantic segmentation and proposes a novel global feature attention network (GFANet) to solve the threat of adversarial attacks. GFANet uses the global context encoder (GCE) to obtain the context dependencies of global features, introduces the global coordinate attention mechanism (GCAM) to enhance the global feature representation to suppress adversarial noise, and the feature consistency alignment (FCA) is used for feature calibration. In addition, a universal adversarial training strategy is constructed to improve the robustness of the semantic segmentation model against adversarial example attacks. Extensive experiments on three aerial image datasets demonstrate that GFANet is more robust against adversarial attacks than existing state-of-the-art semantic segmentation models.
