In the publication of this article [1], there was an error in the Acknowledgements section. The error: ‘This work was supported by the Deanship of Scientific Research (DSR), King Abdulaziz University, Jeddah, under grant No. 130-837-D1435.’ Should instead read: ‘This work was supported by the Deanship of Scientific Research (DSR), King Abdulaziz University, Jeddah, under grant No. D1435-837-130.’ This has now been included in this erratum.
