The effect of storage temperature and time on lipid composition of Scenedesmus sp. was studied. When stored at 4°C or higher, the free fatty acid content in the wet biomass increased from a trace to 62.0% by day 4. Using two-step catalytic conversion, algae oil with a high free fatty acid content was converted to biodiesel by pre-esterification and(More)
The rice blast fungus Magnaporthe oryzae forms a specialized infection structure called an appressorium to breach the host-plant epidermis for successful infection. In this study, a mutant defective in appressorial penetration was isolated by a mutagenesis approach, in which an exogenous DNA fragment was found to be inserted into the first exon of MoCRC1.(More)
Balancing Recall and Precision of rare class in cost-sensitive classification is a general problem. In this paper, we propose a novel cost-sensitive learning algorithm, named Adaptive Cost Optimization (AdaCO), which uses the resampling and genetic algorithm to build convex combination composite classifiers. In every base classifier's building, we use(More)
Subcritical co-solvents extraction of lipid from wet microalgae pastes of Nannochloropsis sp. In this paper subcritical co-solvents extraction (SCE) of algal lipid from wet pastes of Nannochloropsis sp. is examined. The influences of five operating parameters including the ratio between ethanol to hexane, the ratio of mixed solvents to algal biomass (dry(More)
In this paper, we propose a new edge direction histogram (EDH) based on a structural similarity method for image quality assessment. We were motivated by the fact that the structural information of image can be described by the distribution of gradient magnitudes, as well as the one of edge directions. Therefore, we introduce the edge direction histogram to(More)
Major histocompatibility complex (MHC) genes are excellent markers for the study of adaptive genetic variation occurring over different geographical scales. The Chinese egret (Egretta eulophotes) is a vulnerable ardeid species with an estimated global population of 2600–3400 individuals. In this study, we sampled 172 individuals of this egret (approximately(More)
The diet of the skink, Eumeces chinensis (Lacertilia: Scincidae), in Xiamen (Amoy), China was examined using stomach analysis during April and May, and its selection of prey size was tested by feeding trials. Insects (primarily Coleoptera, Lepidoptera, and Orthoptera), gastropods and arachnids constituted most of the E. chinensis diet, but earthworms,(More)
Protein phosphatase 2A is a subgroup of widely conserved serine/threonine phosphatases and plays diverse roles in transcription, translation, differentiation, cell cycle, and signal transduction in many organisms. However, its roles in biotrophic and hemi-biotrophic phytopathogenic fungi remain to be investigated. In this study, we isolated an insertional(More)
This study was to project a powerful volumetric-related parameter on magnetic resonance imaging (MRI) for classifying patients with glioblastoma multiforme (GBM) into distinct subgroups objectively. The preoperative MRIs of 147 patients with primary GBM were analyzed. Volumetric-related parameters, including V1 (tumor volume), V2 (peritumoral T2/FLAIR(More)
Cerebral edema is a major contributor to morbidity associated with traumatic brain injury (TBI). The methods involved in most rodent models of TBI, including head fixation, opening of the skull, and prolonged anesthesia, likely alter TBI development and reduce secondary injury. We report the development of a closed-skull model of murine TBI, which minimizes(More)
