The Kalman filter is an iterative state estimation algorithm employed extensively, including in electricity generation, aerospace, robotics, etc.Inputting noisy measurements on a dynamical system, it outputs a state estimate and associated covariance.This work focuses on the time evolution of the covariance matrix given regular, uniform measurement
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a positive-sense single-stranded RNA virus species with a zoonotic origin and responsible for the coronavirus disease 2019(COVID-19).This novel virus has an extremely high infectious rate, which occurs through the contact of contaminated surfaces and also by cough, sneeze, hand-to-mout
Spatial processes often drive ecosystem processes, biogeochemical cycles, and land-atmosphere feedbacks at the landscape-scale.Climate-sensitive disturbances, such as fire, land-use change, pests, and pathogens, often spread contagiously across the landscape.While the climate-change implications of these factors are often discussed, none of these p
Denosumab, a human monoclonal antibody against RANK ligand, is shown to have strong anti-fracture effects Gels in Japanese osteoporosis patients.However, there have been no data showing actions on Japanese bone architecture.Here we show that denosumab continuously improves several geometrical parameters calculated by hip structural analysis for 3 y
