Rabi oscillations, entanglement and teleportation in the anti-Jaynes-Cummings model
(Cornell University, 2021)This paper provides a scheme for generating maximally entangled qubit states in the anti-JaynesCummings interaction mechanism, so called entangled anti-polariton qubit states. We demonstrate that in an initial vacuum-field, ... -

(Elsevier, 2014-04-01)Accurate detection of carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing carbapenem-resistant Acinetobacter spp. (CP-CRA) constitutes a major challenge in laboratory diagnostics. We developed a ... -
The rate of outcrossing in grain amaranths
(Blackwell Publishing Ltd, 1991-09-01)Studies of intra specific and inter specific out crossing rates were carried out for grain amaranths using two populations of A. hypochondriacus (populations 1008 and 1024) and two populations of A. cruentus (populations ... -
Reaction of Some Coffea arabica Genotypes to Strains of Colletotrichum kahawae, the Cause of Coffee Berry Disease
(Blackwell Publishing Ltd, 2000-01-01)Pathogenicity tests were performed on 11 genotypes of Coffea arabica using single‐isolate suspensions of Colletotrichum Kahawae obtained from 90 monoconidial isolates. The objective of this study was to estimate the ... -
Reactions of Methyl Iodide and Halopropanes with Na0 Treated and Untreated NaX and NaY Zeolites
(Cambridge University Press, 2005)Products formed from reactions of methyl iodide, 1-chloropropane, 1-iodopropane and 1-bromopropane with Na0 treated and untreated NaX and NaY zeolites were studied using solid state 13C NMR and IR spectroscopy. At room ... -
Recent Influences of Anthropogenic Activities and Seasons on Heavy Metal Distribution in Shoreline Sediments in Lake Victoria Near Kisumu City, Kenya
(Journal of Environmental Analytical Chemistry, 2017)The Winam Gulf on Lake Victoria around Kisumu city has seen increase in anthropogenic activities. The activities discharge pollutants, especially heavy metals into the lake. The heavy metals sink into sediments, which ... -
