In this paper, we estimate Hausdorff dimensions of likely limit sets of some p-order Feigenbaum＇s maps. As an application, it is proved that for any 0 〈 t 〈 1, there always exists a p-order Feigenbaum＇s map which has a likely limit set with Hausdorff dimension t. This generalizes some known results in the special case of p =2.展开更多

After briefly breaching 65 cents/lb, the December contract fell sharply over a few of days in mid-August before finding support near 58 cents/lb. In the weeks since, December futures have gradually drifted upwards,
China’s trade surplus probablyfell for a fourth straight month,increasing the likelihood of moregovernment measures to sustainthe economy’s expansion ratherthan stamp out inflation.
According to statistics, China’s domestic clothing consumption averaged an annual growth rate of 14.72 percent from 2001 to 2008, 2009 growth rate is expected to remain more than 15 percent, although exposed

They became dominant in the ancient Earth landscape before the angiosperms and are stil important in current ecosystems.Many ferns have exceptional y high chromosome numbers,possibly resulting from whole-genome duplications(WGDs).However, WGDs have not been investigated molecularly across fern diversity. Here we detected and dated fern WGDs using a phylogenomic approach and by calculating synonymous substitution rates(Ks). We also investigated a possible correlation between proposed WGDs and shifts in species diversification rates. We identified 19 WGDs: three ancient events along the fern phylogenetic backbone that are shared by 66%–97% of extant ferns, with additional lineage-specific WGDs for eight orders, providing strongevidence for recurring genome duplications across fern evolutionary history. We also observed similar Ks peak values for more than half of these WGDs, with multiple WGDs occurring close to the Cretaceous(~145–66 Mya). Despite the repeated WGD events, the biodiversity of ferns declined during the Cretaceous, implying that other factors probably contributed to the floristic turnover from ferns to angiosperms. This study provides molecular evidence for recurring WGDs in ferns and offers important clues to the genomic evolutionary history of ferns.展开更多

Such a system is cumbersome due to its inherent variable time delays, ranging from microseconds to hours. To show the influence of such huge variations in the control performance, a laboratory-scale luminosity system has been setup using the Internet as part of the control loop with dominant time constant in the order of milliseconds. Proportional and integral （PI） control strategies with and without explicit compensation for the time-delay variations were implemented using an event-driven controller. Using the well-known Monte Carlo method and subsequent analyses of time responses, it has been possible to identify the most likely region of stability. Some experimental results show the influence of the statistical parameters of the delays on the determination of the most likely regions of stability of the NCS and how these can be used in assessment and redesign of the control system. The experiments show that much larger delays than one sample period can be supported by real NCSs without becoming unstable.展开更多
