BAP31 is frequently overexpressed in patients with primary colorectal cancer and correlates with better prognosis

We previously showed that B cell receptor associated protein 31(BAP31) was significantly upregulated in colorectal cancer compared with normal mucosa epithelia. However, its expression pattern and pathological role in colorectal cancer are not clearly understood. In this study, we investigated whether the expression of BAP31 was associated with the clinicopathological parameters of colorectal cancer. The expression pattern of BAP31 was detected by immunohistochemistry on a tissue microarray in both primary ...     

The ninth-mode sectorial oscillation of acoustically levitated drops

We report on the ninth-mode sectorial oscillation of acoustically levitated drops excited by actively modulating sound pressure. A numerical computation based on the level set method was performed to model drop shape evolution by solving an incompressible two-phase flow problem. The calculated shapes of the oscillating drop are in good agreement with experimental observations. The relationship between the oscillation frequency and parameters describing the flattened drops is studied both experimentally and numerically. The frequency of the ninth-mode sectorial oscillation decreases with increasing equatorial radius and can be well-described by a modified Rayleigh equation.

甘肃省城市体系空间结构现势评价

从空间结构理论的角度审视,甘肃省城市体系空间结构评价对于落实本区域"十二五"规划有着战略意义。以甘肃省14个地市(州)为研究对象,通过构建城市人口与经济发展指标体系,运用重力模型、断裂点理论等研究方法,综合分析该省城市体系空间结构现势,并对其城镇化水平进行评价。结果表明:该研究区域城市处于要素集聚发展时期,城市等级规模体系尚不完善,发展层次悬殊,核心城市与区域副中心城市对外围地域的带动作用还未充分发挥;超大城市超前发展、大中城市发展不足、小城市层次过低;调适城市空间体系现势的策略只能逐渐满足整合发展要素、缩小发展差距的内在需求。
