摘要：According to the structure features of Fe80P20, A series of clusters Fe4P were designed and focused on studying the stability of local structure, charge distribution and chemical bond, Using the DFT method, energy and structure of Fe4P clusters were optimized and analyzed. The computational results showed that the energy of cluster 1（2） has the lowest energy, and the possibility of its existence in the Fe80P20 is high. Analyzing the transition states among the clusters, it was found that the clusters in the doublet state are more stable than those in the quartet state. The numbers of the Fe-P bond in the clusters play important roles in the cluster stability and electrons transfer properties, The more numbers of Fe-P bonds in the clusters, the higher the cluster stability, and the weaker the ability of P atom to get electron, The number of Fe atoms, which has bonding interactions with the P atom, is direct proportional to the average 3d orbit population of Fe atom. Basing on the orbital population, average magnetic moments of each Fe atom in the Fe4P clusters were calculated, and they are all smaller than that of single metal Fe atom. This suggests that all Fe4P clusters have soft magnetic property and they are expected to be perfect material for preparing soft magnetic apparatus.

摘要：随着新品消费市场日益增长,各大电商平台纷纷推出专为新品发布设计的子平台,面对平台的流量优势和竞争环境,品牌商合理的新品信息披露渠道的选择对提升品牌竞争力十分重要。文章基于贝叶斯原理,刻画忠实消费者和潜在消费者信息更新过程,建立官网渠道披露、平台渠道披露以及平台-官网均披露3种模式下新品定价博弈模型,分析平台信息披露量、平台流量优势对品牌商信息披露渠道选择的影响。研究发现:在平台披露信息量比官网披露信息量更丰富的情形下,当品牌商潜在市场规模较大时,随着平台流量优势的增加,平台-官网均披露模式占优,若平台流量优势较小,品牌商选择官网渠道披露模式并披露较少的信息量更优;在平台披露信息量小于官网的情形下,当平台流量优势较大且潜在市场规模较小时,平台渠道披露模式占优。

摘要：The presence of anti-p53 antibody in serum is a biomarker for cancer. However, its high sensitivity detection is still an issue in cancer diagnosis. To tackle this challenge, we used fd phage, a human-safe bacteria-specific virus nanofiber that can be mass-produced by infecting host bacteria in an error-free manner, and genetically engineered it to display a peptide capable of recognizing and capturing anti-p53 antibody on its side wall. We employed the resultant phage nanofibers as a capture probe to develop a modified version of the enzyme- linked immunosorbent assay （EliSA） method, termed phage-EliSA. We compared it to the traditional EliSA method for the detection of anti-p53 antibody, p53-EliSA, which uses recombinant wild-type p53 protein to capture anti-p53 antibody. We applied phage-EliSA to detect anti-p53 antibody in an experimental group of 316 patients with various types of malignant tumors. We found that a detection rate of 17.7% （56 positive cases） was achieved by phage-EliSA, which was comparable to the detection rate of 20.6% for p53-EliSA （65 positive cases）. However, when both phage and p53 were combined to form antibody-capturing probes for phage/p53-EliSA, a detection rate of 30.4% （96 positive cases） was achieved. Our work showed that owing to the combined capture of the anti-p53 antibody by both phage nanofibers and p53, the phage/p53-EliSA achieved the highest diagnostic accuracy and detection efficiency for the anti-p53 antibody in patients with various types of cancers. Our work suggests that a combination of nanofibers and antigens, both of which capture antibody, could lead to increased detection sensitivity, which is useful for applications in the life sciences, clinical medicine, and environmental sciences.

摘要：流传于市井的时调艺术以其俚俗时行的特质,与清末启蒙思潮正相契合,因而被一些感时忧世的爱国文人所关注、重视并加以利用,成为开启民智、再造人心、救亡图存、改良社会的利器。启蒙者根据清末流行的时调曲调新填的曲词,已经完全跳出儿女情思、古人古事、市井俗态的窠臼,不但在题材内容、创作动机等方面呈现出新的质素,不论是感慨时政、劝戒恶俗,还是破除迷信、介绍新知,无不体现出"启蒙救亡"的特色,而且承载着救亡图存的爱国精神及强身—强种—强国、男女平等平权与维新图强的思想,因而老树发新芽,在清末社会启蒙运动中扮演着重要角色。发掘时调艺术在清末启蒙思潮中所起的积极作用,对于清末社会启蒙运动研究的推进及重新评估时调之类的民间文艺的价值不无裨益。
