Thermal infrared italian mediterranean buffalo udder open dataset with expert-verified segmentation masks
This data article describes an open dataset of thermal images of buffalo udders curated for pixel-level segmentation, the first publicly accessible open dataset on the topic. Images were acquired in situ at a commercial farm in southern Italy over '1 year during routine robotic milking, using a fixed, rear-facing long-wave infrared camera (640×480 resolution) positioned at approximately 1 m, with emissivity set to 0.98. Environmental measurements (ambient temperature and relative humidity) from a nearby station were recorded at capture time and used for temperature compensation before min–max conversion to single-channel 8-bit PNGs. The release contains 2148 image–mask pairs organised in predefined train/validation/test splits. Two veterinarians produced udder masks with polygonal annotation following a shared protocol and resolving disagreements by consensus. The dataset is intended to support reproducible research on udder-region segmentation, a necessary preprocessing step before extracting udder skin surface temperature (USST) in mastitis-oriented studies of dairy animals but not limited to only mastitis. Beyond udder health, thermal computer vision tasks in veterinary science include behaviour monitoring and localisation of anatomical regions for temperature tracking. Labelled thermal segmentation data can also serve as source material for pretraining and transfer to such applications

Seismic assessment of rocking nonstructural elements: advances, challenges, and future directions
Freestanding nonstructural elements are often governed by rigid motion under seismic actions, and relatively slender elements are likely to be governed by rocking behavior. Rocking behavior can be critical since (a) it could be activated under relatively low intensity actions, (b) it could be associated with relatively large rotation amplitudes and displacements, and (c) it is highly nonlinear and unstable. The study critically reviews the literature and code provisions regarding the seismic assessment of nonstructural elements governed by rocking motion, also accounting for building contents. Theoretical, experimental, numerical, and observational methods and applications are examined to highlight recent advances, current limitations and challenges, and future directions. The motivation stems from the observation that, although several studies have addressed this issue over the past decade, literature remains fragmented, and it lacks coordinated programmatic development strategies. Indeed, the exceptional recent growth in this field underscores the need for a comprehensive synthesis of findings, clearer identification of unresolved issues, and the establishment of consistent research trajectories aimed at enhancing seismic safety and mitigating the risk associated with rocking nonstructural elements. To this end, the present paper identifies critical knowledge gaps and methodological limitations, offering interpretative insights and outlining potential research pathways
