In e-learning environment, web-based testing system can help to evaluate learners learning status precisely. To meet the needs of multiple assessment criteria, a new test-sheet construction model was proposed. Based on the proposed model, a differential evolution algorithm with effective coding strategy was designed to generate high quality test-sheets for(More)
Feature extraction and analysis are the foundation of audio classification. At first, audio features are analyzed deeply, including short-time energy, zero-crossing rate, bandwidth, low short-time energy ratio, high zero-crossing rate ratio, and noise rate. Secondly a new audio classification method for news video is proposed based on the decision tree(More)
Differential evolution has emerged as one of the fast, robust, and efficient global optimization approach of current interest. In this paper, an application of Differential Evolution to the location management problem in mobile computing is described. To improve the convergence rate and the quality of solutions of the differential evolution algorithm, an(More)
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Although recent advances in therapeutic approaches for treating HCC have improved the prognoses of patients with HCC, this cancer is still associated with a poor survival rate mainly due to late diagnosis. Therefore, a diagnosis must be made sufficiently early to(More)
Hepatocarcinogenesis in human chronic liver diseases is a multi-step process in which hepatic precancerous lesions progress into early hepatocellular carcinoma (HCC) and progressed HCC, and the close surveillance and treatment of these lesions will help improve the survival rates of patients with HCC. The rapid development and extensive application of(More)
In e-learning environment, computer-aided test-sheet composition play an important role in computer-aided testing systems. To meet the needs of multiple assessment criteria, a new test-sheet construction model was proposed. Based on the proposed model, a discrete differential evolution algorithm with effective coding strategy was designed to generate high(More)
Long non-coding RNAs (lncRNAs) are a subgroup of non-coding RNA transcripts greater than 200 nucleotides in length with little or no protein-coding potential. Emerging evidence indicates that lncRNAs may play important regulatory roles in the pathogenesis and progression of human cancers, including hepatocellular carcinoma (HCC). Certain lncRNAs may be used(More)
We report the magnetic properties, microstructure and surface morphology of epitaxially grown Fe<sub>2</sub>CrSi films. Highly ordered B2 films were obtained by deposition at room temperature followed by annealing at 400&#x00B0;C. Magnetic tunnel junctions using Fe<sub>2</sub>CrSi show a tunnelling magnetoresistance (TMR) of 2.5%. The low TMR is ascribed to(More)
AIM To perform a comprehensive investigation into the potential correlation between circulating myeloid-derived suppressor cells (MDSCs) and Th17 cells in esophageal cancer (ECA). METHODS A total of 31 patients newly diagnosed with ECA and 26 healthy subjects were included in the current study. The frequencies of MDSCs and Th17 cells in peripheral blood(More)
