The IEEE 802.16e standard is a rapidly developing technology for broadband wireless access system. Its PHY OFDMA mode defines two subchannel building methods: diversity permutation and contiguous permutation (AMC subchannel). In this paper we propose a joint packet scheduling and subchannel allocation scheme applicable for the IEEE 802.16e OFDMA AMC(More)
In this study, we investigated the time-dependent expression of IL-1beta, COX-2, MCP-1 mRNA after incised wounds in rabbit skin using real-time fluorescent quantitative PCR. The tested wound ages were distributed as following: <0.5h, 0.5h, 1h, 2h, 3h, 4h, 5h, 6h, 8h, 12h, 24h, 2d, 3d, and 7d. The expressions of three markers in postmortem wounds were(More)
The forensic investigator is frequently confronted with the discrimination and deduction of injury implements, which is one of the most important physical testimonies in courts. The usual method used in actual cases is from points of morphology. In the forensic discrimination of injury implements, such as metal implements, the analysis and comparison of(More)
Allele and haplotype frequencies of 11 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex Y Systems (Promega) were determined in a sample of 215 unrelated healthy male individuals of Chinese Tujia ethnic group living in Chongqing (Southwest of China). The gene diversity values of the Y-STRs loci ranged from 0.3757(DYS391) to 0.9170(More)
Phosphate removal from polluted water is crucial to preventing eutrophication. Herein, we present the investigation on phosphate adsorption in aqueous solutions by using lanthanum-doped activated carbon fiber (ACF-La). Various batch sorption conditions, e.g., pH, ionic strength, and temperature were tested, and the adsorption mechanisms were discussed. The(More)
Mesenchymal stem cells (MSCs) are multipotent progenitors that can undergo osteogenic differentiation under proper stimuli. We demonstrated that BMP9 is one of the most osteogenic BMPs. However, the molecular mechanism underlying BMP9-initiated osteogenic signaling in MSCs remains unclear. Through gene expression profiling analysis we identified several(More)
A class of wireless multicast utility optimization problems are considered. Assume network utility is only a function of link throughput and nodes' transmission power. Under a set of physical layer assumptions, the impact of physical and data-link layer configurations to the upper layers in a wireless network can be characterized using a configuration(More)
This paper shows that, under certain conditions, a wireless network can be modeled by a directed configuration graph with possible hyperarc links if the transmission schedule is given. Assume single multicast session. The maximum achievable multicast throughput equals the max-flow min-cut bound of the configuration graph. An optimization framework is(More)
A panel of ancestry informative markers (AIMs) can be used to describe the genetic components of a population and infer the ancestral origin of a DNA sample. In this study, we selected 30 AIMs from 282 SNPs screened from 30 phenotype-related genes based on the genotyping data of 658 samples from nine populations in the HapMap database. Then,a multiplex(More)
The Earth's rotation undergoes changes with the influence of geophysical factors, such as Earth's surface fluid mass redistribution of the atmosphere, ocean and hydrology. However, variations of Earth Rotation Parameters (ERP) are still not well understood, particularly the short-period variations (e.g., diurnal and semi-diurnal variations) and their(More)
