There is a pressing need for more evidence from regions from Western countries to draw conclusive outcomes concerning psychological sciences. Hence, the study intends to develop the Japanese version of the short form of the Five-Factor Narcissism Inventory; (FFNI-SF) to assess reliability and validity, and to explore the psychometric adaptation of a broad range of narcissistic personalities in relation to the Japanese people. Altogether, 449 Japanese undergraduate students took part in this study. The findings denoted that FFNI-SF had an acceptable level of reliability and correlated well with existing Japanese scales. Based on the exploratory factor analysis, the lack of empathy was excluded from grandiosity, yielding an isolated factor. However, the exploratory factor analysis revealed that the lack of empathy had nothing to do with Japanese narcissism.

The location of a protein in a cell is closely correlated with its biological function. At present, it is still a challenge to extract sequence information solely using protein sequence for protein subcellular localization prediction in the current computational biology. In the current paper, we proposed a novel method that coupled the amino acid composition, amino acid hydrophobicity with position specific scoring matrix to predict the subcellular localizations of prokaryotic and eukaryotic proteins. By defined evolutionary difference formula, varying length proteins are expressed as uniform dimensional vectors, which can represent evolutionary difference information between the u residues of a given protein. To perform and evaluate the proposed method, support vector machine (SVM) and jackknife tests are employed. The overall accuracies are 95.1% and 90.9% for prokaryotic and eukaryotic proteins, respectively. Comparison of our results with the previous methods shows that our method may provide a promising method to predict protein subcellular localization prediction.

Based on the properties of gold ore, several effects, such as grinding fineness, system of flotation pharmaceutical, were researched in the flotation experiment. The results showed that with the grinding fineness-0.074mm 65%, pH=8.5, 2# oil 60 g/t, butylxanthate 140 g/t and Butylamine black medicine 50 g/t, good indexes were obtained as the following: grade of Au rough concentrate is3.24g/t, recovery of Au is 36.90%.

Based on the chemical analysis, preliminary classification of ore was done to reduce the content of iron mineral in quartz. The result of tests showed that the grade of quartz concentrate and the recovery are 97.05% and56.79% by adopting a circuit of magnetic- flotation processing.
