Malvids is one of the largest clades of rosids, includes 58 families and exhibits remarkable morphological and ecological diversity. Here, we report a high‐quality chromosome‐level genome assembly for Euscaphis japonica, an early‐diverging species within malvids. Genome‐based phylogenetic analysis suggests that the unstable phylogenetic position of E. japonica may result from incomplete lineage sorting...
For improving the precision of the fingerprint positioning algorithm based on WIFI and decreasing the complexity of the algorithm at the same time, this paper proposed a KNN + Bayes fusion positioning algorithm based on subsection and interpolation. In the process of building fingerprint library, we use the method of linear interpolation to get the fingerprint which is in the middle of adjacent sampling...
As the single location technology is unable to meet the needs of indoor positioning accuracy and stability, we propose and design the PDR (pedestrian dead reckoning)/Wi-Fi method for indoor location in this paper. It includes the stride length calculation method based on velocity trace, gyroscope and electronic compass in combination with Wi-Fi positioning method for direction judgement, and Wi-Fi...
At outdoor environment, GPS can provide accurate location services. But at indoor environment, it can not. In order to realize accurate positioning indoor, we propose a fingerprint localization algorithm based on WiFi in this paper. In the process of our research, we will divide the indoor environment that need provide accurate location services into a certain scale of virtual grid, and tag each vertex...
