Introduction The carbonate-evaporite system contains substantial hydrocarbon resources and serves as an excellent subject for studying dolomitization problem. In the Ordos Basin, the fifth member of the Ordovician Majiagou Formation have extensive carbonate-evaporite deposits. Methods This study utilizes extensive drilling data, thin section microscopic examination, scanning electron microscopy, and a variety of geochemical an...

Calcific aortic valve disease (CAVD) is a cardiovascular disease prevalent in the aging population, resulting in high morbidity and mortality rates. However, the molecular mechanisms underlying CAVD remain unclear. We initially conducted an RNA sequencing analysis of aortic valve leaflets from rats of different ages to identify key genes involved in valvular aging and calcification. Bioinformatics analysis demonstrated that me...

Autonomous underwater manipulation is very important for the robotic and intelligence operations of oceanic engineering. However, a small target often involves limited features and results in inaccurate visual matching. In order to improve visual measurement accuracy, this paper has proposed an improved unsharp masking algorithm to further enhance the weak texture region of blurred and low contrast images. Moreover, an improve...

In the computer vision field, underwater object detection has been a challenging task. Due to the attenuation of light in a medium and the scattering of light by suspended particles in water, underwater optical images often face the problems of color distortion and target feature blurring, which greatly affect the detection accuracy of underwater object detection. Although deep learning-based algorithms have achieved state-of-...
