Abstract Background Desertification could be considered ultimate consequence of land degradation in an ecosystem.Iran with more than 75% arid and semi-arid areas involves fragile and 117 susceptible ecosystems to desertification.We applied a statistical algorithm including regression trees and random forest techniques for determining main factors a
IntroductionBrain-machine interfaces (BMIs) attempt to establish communication between the user and the device to be controlled.BMIs have great challenges to face in order to design a robust control in the real field of application.The artifacts, high volume of training data, and non-stationarity of the signal of EEG-based interfaces are challenges
Femtosecond laser-induced periodic surface structures (LIPSS) have been extensively studied over the past few decades.In particular, the 117 period and groove width of high-spatial-frequency LIPSS (HSFL) is much smaller than the diffraction limit, making it a useful method for efficient nanomanufacturing.However, compared with the low-spatial-frequ
The author argues through an analysis of maritime practice, legal theory and statutory enactments that the pilot is not only an expert adviser but that he takes Twin Panel Rails charge of and conducts a vessel.He distinguishes between conducting and commanding and points out that by recognizing that the pilot conducts a ship no charge in the nowada
