The spatiotemporal order and rhythm dynamics of a complex neuronal network with mixed bursting neurons are studied in this paper. A quantitative characteristic, the width factor, is introduced to describe the rhythm dynamics of an individual neuron, and the average width factor is used to characterize the rhythm dynamics of a neuronal network. An r parameter is introduced to denote the ratio of the short bursting neurons in the network. Then we investigate the effect of the ratio on the rhythm dynamics of the neuronal network. The critical value of r is derived, and the neurons in the network always remain short bursting when the r ratio is larger than the critical value.

The growing size of the multiprocessor systems increases their vulnerability to component failures. It is crucial to local and to replace the fault processors to maintain system's high reliability. The fault diagnosis is the process of identifying fault processors in a system through testing. This paper establishes the t/t-diagnosability of the m-ary n-cube Qn m with m > 3,and shows that the t/t-diagnosabilities of Qn m under the PMC model is 4n-2.

Aiming at the significance of the energy controls of wireless sensor networks, an economical energy consumption algorithm for wireless communicating in Wireless Sensor Networks (WSN) is presented. Based on the algorithm, the maximal system throughput of WSN is analyzed, and the upper bound of throughput of WSN is proposed and proved. Some numerical simulations are conducted and analyzed. The conclusions include that the transmitting radius of sensor node and the parameters of the energy cost function have significant influence upon the throughput, but the monitoring region radius has little influence. For the same transmitting distance, the more the hopping of information trans- mitting, the better the throughput of WSN. On the other hand, for the energy optimization of the whole WSN, the trade-off problem between the throughput capacity and the relay nodes is proposed, and the specific expression of relay hops that minimized the energy consumptions and the maximal throughput of WSN under the specific situation is derived.

The zonal soils in the south subtropical zone of Fujian are lateritic red soils. A type of dark clayeysoils, which was historically defined as lateritic red soils, derived from weathering products of the basalts wasindicated by the investigation results to be markedly different from lateritic red soils and could be classifiedas Typical Hapluderts. They are distributed as complex zones with the lateritic red soils. The vertisolsin this region were considered as a type of lithogenic soils and the vertic chararteristics delay and inhibitthe soils from allitic processes and then formed an independent soil type. The vertisols have higher fertilityand better agricultural production characters than the lateritic red soils. The different ways in utilizing andmanaging these soils arcording to their properties and fertility are also suggested.

Many recent approaches involving site-directed Mutagenesis or random mutagenesis and DNA shuffling havesucceeded in improving the optimum temperature and increasing the thermostability of lipases. In some industrialapplications, the property of lipases require is not a high residual activity after incubated at high temperature, but ahigh optimum temperature for lipase activity, such as the transesterification reaction, which required that lipases areable to react at a high *** Penicillum expansum lipase(PEL) gene was mutated by site-directed Mutagenesis using overlap extensionPCR technique. The amplified DNA fragment was firstly cloned into vector pBluescrip ⅡSK (+), which then wastransformed into E. coli TG1. The digestion by XhoLl and HindⅢand EcoRI/SnaBI and gel analysis showed that
