无论是在发达国家还是发展中国家,集群往往表现为信任过度或信任缺失。只有达到与集群发展阶段相适应的最佳信任,信任才能够为产业集群带来竞争优势。本文从产业集群理论和信任理论入手,将信任水平分为低级信任、中级信任和高级信任,并且从集群企业间互相依赖的角度提出产业集群内企业间最佳信任动态演化机制及相应命题。本文认为,当信任水平与依赖程度相互匹配的时候,集群内企业之间将达到最佳信任。最佳信任将随集群成长阶段的不同而发生动态演化。

寻找一种性能良好的磁性绝缘材料是发展新型多功能量子自旋电子器件至关重要的基础,但是大多数已知的磁性绝缘材料具有居里温度低(<300 K),铁磁性和结构对称性差的特点.本工作中,我们成功设计并制备了一种新型的磁性绝缘体:Bi8Fe2.8Co0.2-Ti2O20Cl,它具有包含五层钙钛矿层的层状Sillen-Aurivillius结构.令人惊讶的是,此种化合物的居里温度达到了约804 K,比未掺杂的奈耳温度提高超过300 K.此外,由于Sillen层的存在,Bi8Fe2.8-Co0.2Ti2O20Cl具有比所有已知相同Co摩尔比掺杂的Aurivillius氧化物更大的剩余磁化强度.X射线吸收光谱(XAS)和X-光磁性圆二色性(XMCD)光谱分析表明,Bi8Fe2.8Co0.2Ti2O20Cl的铁磁性主要是由Co掺杂引起的FeO6八面体的形变和Fe-O-Co的DzyaloshinskiiMoriya(D-M)相互作用所致.

Importance: Immune thrombocytopenic purpura (ITP) is the most common bleeding disorder in children. Despite the highly spontaneously remission, still almost 20% of cases progress into chronic or refractory ITP, which seriously affects children's quality of life. Currently there is no method to predict the initial stage of childhood ITP. Objectives: To evaluate platelet-specific antibodies and compare differences in their expression in childhood ITP to predict clinical progression. Methods: This is a single-center prospective cohort study from April 2014 to October 2015. We enrolled children initially diagnosed as ITP. Anti-GPIIb/IIIa and GPIb/IX antibodies were assayed by enzyme-linked immunoadsorbent assay (ELISA) and patients were followed up for 1 year. We also analyzed the relationship between the expression of the platelet-specific antibodies GPIIb/IIIa and GPIb/IX and their respective clinical prognoses. results: Overall, 134 cases were enrolled including 77 boys and 57 girls with a median age of 19 months (range: 1 to 159). Positive rates of anti-platelet antibodies were 79.8%. After a 1-year observation period, 84.3%were diagnosed as newly diagnosed ITP and 13.4% were diagnosed as chronic ITP. Patients with anti-GPIIb/IIIa antibody had a higher risk for newly diagnosed ITP compared with patients who were anti-GPIb/IX antibody positive only (93% vs 25%, P = 0.005;87% vs 25%, P = 0.014, respectively). There were more anti-GPIb/IX antibody positive only cases, diagnosed as chronic ITP, compared with anti-GPIIb/IIIa antibody positive only cases and double GPIIb/IIIa and GPIb/IX antibody positive cases (75% vs 7%, P = 0.005;75% vs 13%, P = 0.014, respectively). Interpretation: Patients with anti-GPIIb/IIIa antibody (either single or double) were predicted to have a good prognosis, whereas anti-GPIb/IX antibody only predicted a poor prognosis. These results should be confirmed via a larger cohort multicenter study.
