A Small-Sample Target Detection Method of Side-Scan Sonar Based on CycleGAN and Improved YOLOv8

Applied Sciences
Because of their low cost and ease of deployment, side-scan sonars is one of the most widely used underwater survey instruments. However, the complexity of the marine environment and the difficulty in target acquisition limit the detection accuracy of ...

Geo2DGS‐SLAM: Geometry‐Driven SLAM With 2D Gaussian Splatting

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Recent advances in SLAM systems based on 3D Gaussian Splatting have enabled dense and photorealistic scene reconstruction. However, 3DGS‐based methods still suffer from limited geometric awareness due to the lack of normal rendering support, view inconsistency and weak depth constraints, ultimately hindering high‐fidelity geometric ...

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

WAH‐i: Optimising microphone array geometry for customised localisation accuracy

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

Sea Bottom Line Tracking in Side-Scan Sonar Images Using WTMM-Based Edge Detection

Journal of Marine Science and Engineering
The topographic features of the seafloor can be observed clearly via high-resolution side-scan sonar imagery. However, the faithful interpretation of a sonar image depends strongly on the accuracy with which the location of the sea bottom line can be ...

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

Animal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.

CDK4/6 Inhibitors in the Management of Hormone Receptor‐Positive (HR+)/Human Epidermal Growth Factor Receptor 2‐Negative (HER2−) Advanced Breast Cancer in Indonesia: Challenges, Opportunities, and Recommendations

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Evidence‐informed recommendations emphasize the integration of CDK4/6 inhibitors with endocrine therapy as a central component in the management of HR+/HER2− advanced breast cancer in Indonesia. Expanding access and facilitating integration within national treatment frameworks are crucial to improve outcomes and reduce disparities in care.

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...
