A belt conveyor system is one of the essential equipment in coal mining. The damages to belts are hazardous because they would affect stable operation a whilst impairing mining efficiency. To address these problems, novel damage detection method based on CenterNet proposed this paper. fusion feature-wise and response-wise knowledge distillation proposed, which balances performance size deep neural network. Fused Channel-Spatial Attention compress latent feature maps efficiently,...

Abstract Large foreign object transporting by coal mine conveyor belt may lead to production safety hazards. To reduce accidents during mining, a large detection method based on machine vision is proposed in this paper. An adaptive weighted multi-scale Retinex (MSR) image enhancement algorithm improve the captured quality of line. improved template matching designed combining frame difference and area methods screen identify objects mixed coals. The multi-layer perceptron (MLP) network...

Histidine-rich glycoprotein (HRG) displays anticoagulant and antifibrinolytic properties in animal models, but its effects humans are unclear. We investigated serum HRG levels their associations with the disease stage prothrombotic alterations lung cancer (LC) patients. In 148 patients advanced LC prior to anticancer therapy (87 non-small-cell 61 small-cell LC) versus 100 well-matched controls, we measured association clot permeability (K s), turbidimetry (lag phase maximum absorbance),...

Powerful belt conveyor is the crucial transportation equipment for coal mining. Keeping its stable operation essential to ensure mining efficiency. At present, damage detection systems based on machine vision are widely studied and deployed. Clear images foundation successful detection. However, in harsh environment of underground seam, it difficult capture high-quality images, which limits performance vision-based techniques To solve this issue, an image denoising enhancement approach...

Vibration measurement is essential for vibration monitoring and control. Noncontact more applicable in practice than the contact measuring manner, but noncontact methods usually pose a high requirement light field environment. To solve this issue, new binocular vision method proposed to enable with different fields. In method, multitarget objects same image are first recognized by YOLOv5 model generate bounding boxes; meanwhile, depth generated through kept synchronized target image. Then,...

Acute electrical stimulation of vagal nerve changes gut motility, secretion as well absorption, and it may have effect on food intake satiety regulation. The aim the study was to evaluate permanent microchip mediated neuromodulation (McNm) afferent activity GI function body mass in experimental model.Two-steps performed. In first step (evaluation intake) 16 rabbits were divided two groups, 8 animals each. Group A subjected (McNm), control group B sham operated. both groups laparotomy...

Dense fibrin networks resistant to lysis have been reported in patients at high risk of thromboembolism. Little is known about clot properties cancer. We investigated and their determinants with inoperable lung enrolled 150 advanced cancer prior therapy 90 control subjects matched by age, sex, cardiovascular disease, diabetes. Plasma permeability (Ks), turbidimetric analysis formation, time (CLT), microparticle-associated tissue factor (MP-TF) activity, thrombin generation, serum cotinine...

In modern orthopedic surgery, bone drilling is an essential and popular technique used for various purposes such as fracture fixation, grafting, joint arthroplasty, others. This study focuses on measuring analyzing vibration in surgery during to address common issues that may arise. The signal of the drill measured using accelerometer sensors placed near order avoid any unnecessary attenuation. research specifically examines a cow femur its composition similar humans. 50,000 data are...
