Microcystin-RR (MCRR) is among the cyanobacterial toxins of significant concern due to their negative effects on water quality and human health. In this study, periphyton dominated by bacteria and diatoms was applied to remove MCRR from water. The maximum removal rate of MCRR by periphyton was observed in the first day (the latent adaptation period). Within(More)
A proper understanding of communication patterns of parallel applications is important to optimize application performance and design better communication subsystems. Communication patterns can be obtained by analyzing communication traces. However, existing approaches to generate communication traces need to execute the entire parallel applications on(More)
Dissimilatory Fe(III) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(III) reduction predominantly comes from pure cultures of dissimilatory Fe(III) reducing bacteria (DFRB). The objective of this study was to compare the effects of glucose and a selection of short(More)
Communication patterns of parallel applications are important to optimize application performance and design better communication subsystems. Communication patterns can be extracted from communication traces. However, existing approaches to generate communication traces need to execute the entire parallel applications on full-scale systems that are time(More)
By rearranging the data, data layout optimizations improve the utilization of a cache line between two of its successive refills, thus reducing the total number of cache line refills and improving the performance of a program. In this paper, we show that to enable structure data layout optimizations to be effective, two parameters, namely intra-instance(More)
With the approaching of the many-core era, it becomes more and more difficult for a single OpenMP application to efficiently utilize all the available processor cores. On the other hand, the available cores become more than necessary for some applications. We believe executing multiple OpenMP applications concurrently will be a common usage model in the(More)
OBJECTIVE To evaluate the influence of DNA extraction methods on the actinobacteria diversity analysis in saline environment via 16S rDNA Restriction Fragment Length Polymorphism. METHODS CTAB-SDS method, glass bead beating method and repeated freezing and thawing method were used to extract total DNA in soil samples from the Yanqi Salten. The 16S rDNA(More)
The output of organic pollutants and excessive nutrients in intensive agricultural areas has frequently occurred, which easily lead to pollution events such as harmful algal blooms in downstream aquatic ecosystems. A photobioreactor-wetland system was applied to remove UV(254 nm) matter and dissolved nutrients discharged from an intensive agricultural area(More)
NestedMP: Taming Complex Configuration Space of Degree of Parallelism for Nested-Parallel Programs. It is beneficial to exploit multiple levels of parallelism for a wide range of applications, because a typical server already has tens of processor cores now. As the number of cores in a computer is increasing rapidly, efficient support of nested parallelism(More)
