In this work, we study a Markov model of cyber threats that act on a computer system.Within the framework of the model the computer system is considered as a system with failures and recoveries by analogy with models of reliability theory.To estimate functionally-temporal properties of the system we introduce a parameter called the lifetime of the
Abstract Bhas 42 cell transformation assay (CTA) dl0211 has been used to estimate the carcinogenic potential of chemicals by exposing Bhas 42 cells to carcinogenic stimuli to form colonies, referred to as transformed foci, on the confluent monolayer.Transformed foci are classified and quantified by trained experts using morphological criteria.Altho
Alloteropsis semialata (R.Br.) Hitchc.of the Paniceae, would be expected to exhibit typical eupanicoid leaf anatomy with a single cassis crista bundle sheath of large parenchymatous cells with specialized chloroplasts and radially-arranged chlorenchyma.Specimens from South Africa showed the following bundle-sheath and mesophyll deviations from the
This historical study presents an explanation of Saudi influence in the northwest of The Arabian island during the period (1208-1227 AH/ 1793-1812 AD) where the convoys of Shami Hajj and the convoys of the jumbo wind gold Egyptian hajj became directly under the authority and administration of the first Saudi state (1175-1223 AH / 1744-1818 AD) , as
Item analysis is performed by developers as an integral part of the scale development process.Thus, items are excluded from the scale depending on the item analysis prior to the factor analysis.Existing item discrimination indices are calculated based on correlation, yet items with different response patterns are likely to have a similar item discr
