Loop closure detection serves as the fulcrum of improving the accuracy and precision in simultaneous localization and mapping (SLAM).The majority of loop detection methods extract artificial features, which fall short of learning comprehensive data information, but unsupervised learning as a typical deep learning method excels in self-access learni
Introduction and purpose The human gut microbiota consists of trillions of microscopic organisms, mostly bacterias.They play a significant role in nutrient metabolism, maintenance of structural integrity of the gut mucosal barrier, immunomodulation and protection against pathogens.Many factors can influence the composition of the intestinal microbi
Abstract Background Where resources are available, the World Health Organization recommends cervical cancer screening with human papillomavirus (HPV) DNA testing and subsequent treatment cinch hobble strap of HPV-positive women with timely cryotherapy.Newer technologies may facilitate a same-day screen-and-treat approach, but these testing systems
Freeze-thaw damage is one of the main factors affecting the service cinch hobble strap life and durability of concrete.Optimizing the microscopic pore distribution of concrete is an effective measure to improve its frost resistance.This paper takes mixed sand (machine-made sand + river sand) concrete as the research object and analyzes the influenc
AbstractNowadays augmented reality, 3D Image, mixed reality and see-through applications are very attractive technologies due to their great potential.Holographic optical elements can provide interesting solutions for injection and extraction of the image in the waveguides that are part of the see-through kiara sky pixie dust devices.We have develo
