Rock image classification is a fundamental and crucial task in the creation of geological surveys. Traditional rock methods mainly rely on manual operation, resulting high costs unstable accuracy. While existing based deep learning models have overcome limitations traditional achieved intelligent classification, they still suffer from low accuracy due to suboptimal network structures. In this study, model EfficientNet triplet attention mechanism proposed achieve accurate end-to-end...

Remote sensing imagery, despite its broad applications in helping achieve Sustainable Development Goals and tackle climate change, has not yet benefited from the recent advancements of versatile, task-agnostic vision language models (VLMs). A key reason is that large-scale, semantically diverse image-text dataset required for developing VLMs still absent remote images. Unlike natural images, images their associated text descriptions cannot be efficiently collected public Internet at scale....

Abstract Regulating metabolic disorders has become a promising focus in treating intervertebral disc degeneration (IDD). A few drugs regulating metabolism, such as atorvastatin, metformin, and melatonin, show positive effects IDD. Glutamine participates multiple processes, including glutaminolysis glycolysis; however, its impact on IDD is unclear. The current study reveals that glutamine levels are decreased severely degenerated human nucleus pulposus (NP) tissues aging Sprague-Dawley (SD)...

Intervertebral disc degeneration (IDD) is closely associated with low back pain, but its underlying mechanism remains unclear. Cholesterol an essential nutrient in mammalian cells. Alterations cholesterol levels lead to impairments cell physiology, such as proliferation and signal transduction. Previous clinical studies demonstrated that hypercholesterolemia could be a potential risk factor for IDD, how induces IDD unknown. The current study aimed explore the regulatory role of development...

Rotation equivariance has recently become a strongly desired property in the 3D deep learning community. Yet most existing methods focus on regarding global input rotation while ignoring fact that symmetry its own spatial support. Specifically, we consider object detection problem scenes, where an bounding box should be equivariant pose, independent of scene motion. This suggests new call object-level equivariance. To incorporate into detectors, need mechanism to extract features with local...

Intervertebral disc degeneration is mainly caused by irregular matrix metabolism in nucleus pulposus cells and involves inflammatory factors such as TNF-α. Rosuvastatin, which widely used the clinic to reduce cholesterol levels, exerts anti-inflammatory effects, but whether rosuvastatin participates IDD remains unclear. The current study aims investigate regulatory effect of on potential mechanism. In vitro experiments demonstrate that promotes anabolism suppresses catabolism response TNF-α...
