Image encryption methods aim to protect content privacy.Typically, they encompass scrambling and diffusion.Every pixel of the image is permuted (scrambling) and its value is transformed according to a key (diffusion).Although several methods have been proposed in the literature, some of them have been cryptanalyzed.In this paper, we present a novel
The interaction of electrons with strong laser fields is usually treated with semiclassical theory, where the laser is represented by an external field.There are analytic solutions for the free electron wave functions, which incorporate the interaction with the laser field exactly, but the joint effect of the atomic binding potential presents an ob
Background: Erythema multiforme (EM) is an acute cutaneous eruption often associated with infections and more rarely with drugs.This review aimed to evaluate the association between erythema multiforme and coronavirus disease 2019 (COVID-19).Methods: A systematic search of PubMed/MEDLINE, Scimago Scopus, and ISI/Web of Science was performed.Origina
Non-wood fibers such as bamboo and wheat straw have been playing important roles in the pulp and paper industry in China.In this study an ECF-bleached bamboo kraft pulp was compared with a bleached softwood kraft pulp (NBSK) as the reinforcement pulp in fine paper production.Areas that were examined include the refining of pure fibers, A Vitamins i
The development of biofilm on the surface of filtration membranes is the main fouling component of water filtration systems.Chemical cleaning is only partially effective in removing biofilm components from the membrane surface.In order to identify opportunities to improve the efficiency of commercial cleaning solutions used in nanofiltration, we co
