In this note we present a reconstructive algorithm for solving the cross-sectional pipe area from boundary measurements in a tree network with one inaccessible end.This is equivalent to T-shirt reconstructing the first order perturbation to a wave equation on a quantum graph from boundary measurements at all network ends except one.The method prese
Influence and its suppression of desired signal coupling to reference signal to interference cancellation system
The time-domain characteristics of adaptive interference cancellation system with desired signal coupling to reference signal were analyzed.The analyses reveal the desired signal makes the system a time-variation system and the optimal weights were changed,which made the performance of cancellation system decreased and infulence the reception of th
Association between falls in elderly and the number of chronic diseases and health-related behaviors based on CHARLS 2018: health status as a mediating variable
Abstract Objective Falling is one of the main causes of death and morbidity in the elderly.This study aims to explore the association between elderly patients with chronic diseases and their health-related behaviors and falls in the elderly, and to provide clues for the prevention and intervention of injuries caused by falls in the elderly.Methods
