Traditional RF-based indoor positioning approaches use only Radio Signal Strength Indicator (RSSI) to locate the target object. But RSSI suffers significantly from multi-path phenomenon and other environmental factors. Hence, localization accuracy drops dramatically in a large tracking field. To solve this problem, paper introduces one more resource, dynamic of RSSI, which is variance signal strength caused by object robust environment changes. By combining these two resources, we are able...
Normal form (NF) theory is used to characterize and quantify nonlinear modal interaction near critical equilibria. This study focuses on the analysis of second-order aspects system behavior which are interest design location controllers. A systematic approach deriving NF representations in neighborhood equilibrium points presented. On basis this model, measures then obtained assess extent distribution nonlinearity system. Analytical criteria developed predict existence interactions that...
Fluorescence imaging in the near-infrared II (NIR-II, 1000-1700 nm) region opens up new avenues for biological systems due to suppressed scattering and low autofluorescence at longer-wavelength photons. Nonetheless, development of organic NIR-II fluorophores is still limited mainly shortage efficient molecular design strategy. Herein, we propose an approach designing Janus by introducing electronic donors with distinct properties into one molecule. As a proof-of-concept, fluorescent dye 2 TT-
Given two sets of points, S and T, in a road network, G, distance-preserving subgraph (DPS) query returns G that preserves the shortest path from any point to T. DPS queries are important many real world applications, such as route recommendation systems, logistics planning, all kinds shortest-path-related applications run on resource-limited mobile devices. In this paper, we study efficient algorithms for processing large networks. Four proposed with different tradeoffs terms quality time,...
In Location-Based Services, Point-Of-Interest(POI) recommendation plays a crucial role in both user experience and business opportunities. Graph neural networks have been proven effective providing personalized POI services. However, there are still two critical challenges. First, existing graph models attempt to capture users' diversified interests through unified graph, which limits their ability express various spatial-temporal contexts. Second, the efficiency limitations of construction...
