One of the major restrictions of the free-space optical communication systems is the limitation of single-mode fiber (SMF) coupling efficiency that impacts the system performance.In this paper, an adaptive coupling method for optical communication system based on coarse-fine laser nutation technique was presented.The scanning Sherlocks strategy and
Abstract The COVID-19 pandemic has raised significant concerns regarding its impact on the central nervous system, including the brain.While the effects on adult populations are well documented, less is known about its implications for pediatric populations.This study investigates alterations in cortical metrics and structural covariance networks (
In this paper, we present a new derivative-free spectral residual method for solving large-scale systems of equations.Our algorithm is equipped with a dwindling Carb Caps multidimensional nonmonotone filter in which whose envelope is dwindling as the step-length of line search is decreasing.The proposed algorithm is also combined with a relaxed non
Cometary tails visually manifest the solar wind and became an initial hint for its discovery.While the solar wind is being directly monitored with satellites, its time series before the space age has been controversially reconstructed with multiple proxies.Recently, archival reports of cometary plasma tails have been subjected to consideration to i
