In this paper, we provide an asymptotic performance analysis of channel-aware packet scheduling based on the extreme value theory. We first address the average throughput of systems with a homogeneous average signal-to-noise ratio (SNR), and obtain its asymptotic expression. Compared with the exact throughput expression, the asymptotic one, which is(More)
Continuous measurements of atmospheric organic and elemental carbon (OC and EC) were taken during the high-pollution fall and winter seasons at Xi’an, Shaanxi Province, China from September 2003 through February 2004. Battery-powered mini-volume samplers collected PM2.5 samples daily and PM10 samples every third day. Samples were also obtained from the(More)
Abstract Purpose. To establish a hepatocellular carcinoma (HCC) cell line from lung metastatic lesions of human HCC in nude mice so as to provide a suitable model for the study of lung-metastasis-related molecular mechanisms. Methods. HCC clone cells MHCC97-H were inoculated into BALB/c nude mice, and the pulmonary metastatic lesions were harvested and(More)
In this paper, we study the problem of packing unequal circles into a 2D rectangular container. We solve this problem by proposing two greedy algorithms. The first algorithm, denoted by B1.0, selects the next circle to place according to the maximum hole degree rule, which is inspired from human activity in packing. The second algorithm, denoted by B1.5,(More)
Normal maize germplasm could be used to improve the grain yield of popcorn inbreds. Our first objective was to locate genetic factors associated with trait variation and make first assessment on the efficiency of advanced backcross quantitative trait locus (AB-QTL) analysis for the identification and transfer of favorable QTL alleles for grain yield(More)
Grain yield is the most important and complex trait in maize. In this study, a total of 258 F9 recombinant inbred lines (RIL), derived from a cross between dent corn inbred Dan232 and popcorn inbred N04, were evaluated for eight grain yield components under four environments. Quantitative trait loci (QTL) and their epistatic interactions were detected for(More)
It has been claimed that engineering traits into the chloroplast will prevent transgene transmission by pollen, precluding transgene flow from crops. A Setaria italica (foxtail or birdseed millet) with chloroplast-inherited atrazine resistance (bearing a nuclear dominant red-leaf base marker) was crossed with five male-sterile yellow- or green-leafed(More)
Four hundred and seventy-eight microsatellite markers derived from expressed sequence tags (EST-SSRs) were screened among three mapping populations (W-7984×Opata 85, WOpop; Lumai×Hanxuan, LHpop; Wenmai×Shanhongmai, WSpop). The number of polymorphic EST-SSR primer pairs found in WOpop, LHpop and WSpop was 92, 58 and 29 respectively. A total of 101 EST-SSR(More)
We report here the transformation of two species of orchid, Dendrobium phalaenopsis and D. nobile, by biolistic bombardment. Calli or protocorm-like bodies (PLBs) were used as target explants. Gold particles (1.0 µm) coated with plasmid DNA (pCAMBIA1301) encoding an intron-containing β-glucuronidase gene (gus-int) and a hygromycin phosphotransferase (hpt)(More)
Due to the characteristics of wireless channels, utility-based resource management in wireless networks requires a set of mechanisms that are different from those for wireline networks. This paper explores in detail why and how the requirements are different. In particular, we analyze the wireless network performance to find out the scheduling algorithm(More)
