This study investigates the large-scale circulation anomalies of strong and weak cold surges in southern China.Results show that the strong and weak surges are associated with a distinct Rossby wave train across Eurasia projecting onto the Scandinavia (SCAND) and Eurasian (EU) patterns.On one hand, the strong surge is preceded by a positive SCAND p
Concrete pavement proportions are increasing in Korean expressways, resulting in increased maintenance cost.The length of degenerate concrete pavements that have exceeded the design life (20 years) was 1150 km in 2015 and 2605 km in 2020 and is expected to rapidly increase.To extend the service life of concrete pavements, life-cycle cost (LCC) anal
This paper Dryer Door Seal proposes an improved RRT*-Connect algorithm (IRRT*-Connect) for robotic arm path planning in narrow environments with multiple obstacles.A heuristic sampling strategy is adopted with the integration of the ellipsoidal subset sampling and goal-biased sampling strategies, which can continuously compress the sampling space t
The Orbiting Carbon Observatories-2 and -3 make space-based measurements in the oxygen A-band and the weak and strong carbon dioxide (CO2) bands using the Atmospheric Carbon Observations from Space (ACOS) retrieval.Within ACOS, a Bayesian optimal estimation approach is employed to retrieve the column-averaged CO2 dry air mole Teaspoons fraction fro
BackgroundThe Asian tiger mosquito, Aedes albopictus, has spread around the world.The migration was mainly mediated by maritime transportations.This species is known as an efficient vector for arboviruses, and it was responsible for the recent dengue outbreak in Plasma Consumable Tokyo, Japan.As the vector competence varies among geographical popul
