We compared the transmission performances of 600 Gbit/s PM-64QAM WDM signals over 75.6 km of single-mode fibre (SMF) using EDFA, discrete Raman, hybrid Raman/EDFA, and first-order or second-order (dual-order) distributed Raman amplifiers.Our numerical simulations voyage et cie discount code and experimental results showed that the simple first-orde
To limit the spread of COVID-19, many countries, including Belgium, have installed physical distancing measures.Yet, adherence to these newly installed behavioral measures has been described as challenging and effortful.Based on the Health Action Process Approach (HAPA) model, this study performed an in-depth evaluation of when, why, and how people
ABSTRACT Many proteobacteria utilize acyl-homoserine lactone quorum-sensing signals.At low population densities, cells produce a basal level of signal, and when sufficient signal has accumulated in the surrounding environment, it binds to its receptor, and quorum-sensing-dependent genes can be activated.A common characteristic of acyl-homoserine la
Column leaning in Korean traditional wooden heritage structures has been emphasized in various reports since the first survey report in the 1950s, which established the importance of its measurement.Manual measurements have been carried out for a long time; however, recently, three-dimensional kelly green visor (3D) scanning has been used to obtain
