Global Navigation Satellite Systems (GNSSs) frequently encounter challenges in providing reliable navigation and positioning within urban canyons due to signal obstruction.Micro-Electro-Mechanical System (MEMS) Inertial Measurement Units (IMUs) offers an alternative for autonomous navigation, but they are susceptible to accumulating errors.To mitig

It has been uncertain what types of erythematous gastric mucosa are produced by Helicobacter pylori (H.pylori)-infection.We therefore design the present study to identify the type of erythematous mucosa associated with H.pylori-infection.A PCB total of 590 consecutive Japanese patients (mean age 58.7 years, 185 men and 405 women) referred to our ho

ARGO-M is a satellite laser ranging (SLR) system developed by the Korea Astronomy and Space Science Institute with the consideration of mobility and daytime and nighttime satellite observation.The ARGO-M optical system consists of 40 cm receiving telescope, 10 cm transmitting telescope, and detecting optics.For the development of ARGO-M optical sys
