As a fundamental concept, geometry is widely used in understanding physical phenomena. In quantum mechanics, related to the system’s state and can be characterized by geometric tensor (QGT), whose real part referred as metric (QMT), which defines distance between two neighboring states projected Hilbert space. Several pieces of research based on discrete variables have been proposed extract QMT...

Tree diameter at breast height (DBH) is the most fundamental factor in modelling tree growth, but current DBH measurement instruments mainly focus on instantaneous acquisition, making it difficult to measure growth continuously and accurately. In this study, we propose a wireless sensing network that can transmit data signal-free environments, combine sensor computer technologies develop real-t...
