Normal mixture distributions are arguably the most important mixture models, and also the most technically challenging. The likelihood function of the normal mixture model is unbounded based on a set of random samples, unless an artificial bound is placed on its component variance parameter. Moreover, the model is not strongly identifiable so it is hard to(More)

Metastasis-associated in colon cancer-1 (MACC1) expression in tumor specimens is an independent prognostic indicator of metastasis, which has recently gained considerable attention in cancer research, due to its overexpression in several types of carcinoma. However, MACC1 expression patterns and its possible role in renal cell carcinoma remain unknown. This(More)
As a significant metal chalcogenide, copper sulfide (Cu2-xS, 0 < x < 1), with a unique semiconducting and nontoxic nature, has received significant attention over the past few decades. Extensive investigations have been employed to the various Cu2-xS micro-/nanostructures owing to their excellent optoelectronic behavior, potential thermoelectric properties,(More)
Two series of phosphors, α-Sr2(1-x)Dy2xP2O7 and α-Sr2(1-2x)Dy2xLi2xP2O7, with different x values were synthesized successfully using a conventional solid-state method at high temperature for the first time, and their luminescence properties were investigated comparatively. The effect of Li(+) ions on the luminescence properties of Dy(3+) in α-Sr2P2O7 host,(More)
In this study, we aimed to identify the influence of exonuclease 1 (EXO1) single-nucleotide polymorphism rs9350, which is involved in DNA mismatch repair, on prostate cancer risk in Chinese people. In our hospital-based case–control study, 214 prostate cancer patients and 253 cancer-free control subjects were enrolled from three hospitals in China.(More)
In order to solve the maintenance outsourcing pattern choosing problem for mechanical manufacturing enterprises equipment, a two stage maintenance outsourcing patterns choosing model based on core competence theory and AHP is proposed which aims at different equipments. For key equipment, the model claims strategic outsourcing pattern and then chooses core(More)
