We compared the transmission performances of 600 Gbit/s PM-64QAM WDM signals over 75.6 km of rk559 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 and experimental results showed that the simple first-order distributed Raman sc
Abstract Background The targeting accuracy of proton therapy (PT) for moving soft-tissue tumours is expected to greatly improve by real-time magnetic resonance imaging (MRI) guidance.The integration of MRI and PT at the treatment isocenter would offer the opportunity of combining the unparalleled soft-tissue contrast and real-time imaging capabilit
Monitoring mechanisms that ensure efficient crop growth are essential on many farms, especially in certain areas of the planet where water is scarce.Most farmers must assume rk559 the high cost of the required equipment in order to be able to streamline natural resources on their farms.Considering that many farmers cannot afford to install this equ
