An adaptive algorithm for reliable multicast in mobile cellular networks was proposed, with which, the information between the base stations and their neighborhoods was exchanged through a dedicated multicast group to control the amount of packets stored in their buffers.

Methods Fourteen male New Zealand white rabbits were assigned to 2 groups randomly. One of the groups were perform CE-MRA with USPIO or Gd-DTPA, and a week delay, to ensure the excretion of contrast agent, perform the MRA with the other contrast agent.

Even the group switching from twice to multiple injections did not improve blood glucose control and the increase in body mass index was most pronounced in this group.

Microprocess measurement channel under group switching of resistive sensors

This mapping is used to switch the application pointers when group switching occurs.

In this paper, the idea of vertex-exchange between two subgraphs in Ref. [1] is extended to vertex-permutation among k subgraphs and a kind of efficient algorithm on the optimal k-partitioning of the graphs is presented by applying the procedure for solving extended assignment problems to one for solving this partitioning problem. The theoretical proof of the convergency of this algorithm is also given. Furthermore, the algorithm on the optimal k-partitioning of the graphs is extended to that of fhe case in...

Furthermore, the algorithm on the optimal k-partitioning of the graphs is extended to that of fhe case in which the number of partitions is not given and the number of elements in each partition is not necessarily equal.

A mathematical model of hot strip mill rolling scheduling problem (HSMRSP) is formulated. A hybrid heuristic method is proposed based on parallel strategy.The approach consists of three stages. The first stage is to classify and sort production orders to generate an initial solution by applying the domain expertise. The second stage is to improve the initial solutions with genetic algorithm (GA) . The third stage is to generate the final results by adopting tabu search (TS) based on swaps of single slab...

Aim To observe the anti caries effect of sodium fluoride gelatin microspheres in encapsulating sodium fluoride in vitro and vivo of the rabbits and investigate its application prospect as new type of fluoride agent. Methods The in vitro fluoride releasing profiles of NaF GMS in saline and artificial saliva (pH4.0, pH6.8 respectively), as well as Rabbits' salivary fluoride concentrations before and after topical administration of NaF GMS and NaF solutions were tested using a fluoride electrode at different...

Aim To observe the anti caries effect of sodium fluoride gelatin microspheres in encapsulating sodium fluoride in vitro and vivo of the rabbits and investigate its application prospect as new type of fluoride agent. Methods The in vitro fluoride releasing profiles of NaF GMS in saline and artificial saliva (pH4.0, pH6.8 respectively), as well as Rabbits' salivary fluoride concentrations before and after topical administration of NaF GMS and NaF solutions were tested using a fluoride electrode at different times. Six rabbits were divided into two groups equally and treated with microspheres and solutions of equal amount of fluorine respectively.The concentration of fluorine was measured.Results The study showed that fluoride releasing kinetics in vitro fitted to first order equations.In saline,the equation was ln(85.49 P)=- 0.028t+ 4.448,T1/2 was 24.75 min,while the T1/2 of NaF solution was 5.05 min. It could be concluded from this point that the NaF GMS had a slow release property. Moreover, data in artificial saliva of pH4.0 and pH6.8 following the equations of ln(87.88- P)=- 0.033t+ 4.004,(T1/2=21.0 min) and ln(88.06- P)=- 0.031t+ 3.986, (T1/2=22.64 min) respectively.Rabbits' salivary fluoride concentration were higher than base level at least in 90min in NaF GMS group( t=4.267,P< 0.05) ,while in NaF solution group that was (27± 5)min. Conclusion The experiment indicates that NaF GMS has slow release property in vitro and their fluoride release rate increases in pH4.0 artificial saliva.Fluoride gelatin microspheres may be an efficient topical fluoride agent.Experiments conducted in rabbits' oral cavity using NaF GMS and NaF solution as control reveal that NaF GMS maintains oral fluoride retention longer than NaF solution dose. NaF GMS is anticipated to be a new type of anti caries fluoride agent.
