With the aid of symbolic-numeric computation, we use the scheme to study the function projective synchronization between 2D Lorenz discrete-time system and Hdnon discrete-time system, as well as that between 3D discrete-time hyperchaotic system and Henon-like map via three scalar controllers, respectively. Moreover numerical simulations are used to verify the effectiveness of the proposed scheme.展开更多

Data were collected between April 2009 and April 2010 from randomly selected Holstein crossed breed dairy cow and heifer （30 cows ＇,and 10 heifers） on faculty farm of faculty of Natural Resources Rajamangala University of Technology Isan, Skon-nakon Campus. Blood samples were collected weekly from each cow, starting 2 weeks before expected calving until 4 weeks postpartum. Serum was analyzed for NEFA and BHBA. The critical threshold for [NEFA] was defined as： 〉 0.4 mmol/L when 〈 -7 to 0 DIM, and 〉 0.7 mmol/L when 3 DIM. Postpartum sub-clinical ketosis （SK） was defined using [BHBA] 〉 14.4 mg/dl. The prevalence of elevated NEFA was 82.5%, 27.5%, 27.5% 7.5% and 7.5% in the dry period, 1st, 2nd 3rd and 5th weeks of lactation, respectively. The prevalence of SK was 12.5% at 2nd weeks of lactation. High prevalence of elevated NEFA during dry period through first 2 weeks of postpartum indicated that periparturient dairy cows suffered some degree of negative energy balance （NEB）. These resulted indicated that though, milk yield of these cows were not that high, NEB and ketosis are still major nutrient-related problems.展开更多

In the teleportation scheme Bell state measurements （BSMs） are difficult for physical realization, so we investigate another strategy using separate measurements instead of BSM based on cavity quantum electrodynamics techniques. The scheme of two-atom entangled state teleportation is a controlled and probabilistic one. For the teleportation of the three-atom entangled state, the scheme is a probabilistic one. The fidelity and the probability of the successful teleportation are also obtained.展开更多
