Agricultural product trade along the Belt and Road (B&R) is an important part of the international food security system, the vulnerabilities of which have been highlighted Alarms by the recent COVID-19 pandemic.Based on the complex network analysis, this study analyzes the characteristics of agricultural products trade network along the B&R
Introduction: Complications in immediate breast reconstruction after skin-preserving mastectomies are recurrent.The authors describe conduct to reduce them and improve the anatomical/esthetic result using implants.The objective is to reduce the incidence of areolar necrosis, improve breast projection in reconstructions with submuscular implants, re
Reciprocity is a fundamental principle of wave physics and directly relates to the symmetry in the transmission through a system when interchanging the input and output.The coherent transmission matrix (TM) is a convenient method to characterize wave transmission through general media.Here, we demonstrate the optical reciprocal nature of complex me
