This article presents a general pinhole channel reference model based on the cause of pinhole effect. On the base of this reference model, a deterministic simulation model is developed by keeping the difference of correlation properties between reference and simulation model as smaller as possible. The correlation properties include temporal autocorrelation fimction （ACF）, two-dimensional （2-D） space cross-correlation function （CCF） and frequency correlation function （FCF）. The results show that although pinhole channel has good correlation properties, the channel capacity is very low because of the low rank of channel transform matrix.

Current multi-operator image resizing methods succeed in generating impressive results by using image similarity measure to guide the resizing process. An optimal operation path is found in the resizing space. However, their slow resizing speed caused by inefficient computation strategy of the bidirectional patch matching becomes a drawback in practical use. In this paper, we present a novel method to address this problem. By combining seam carving with scaling and cropping, our method can realize content-aware image resizing very fast. We define cost functions combing image energy and dominant color descriptor for all the operators to evaluate the damage to both local image content and global visual effect. Therefore our algorithm can automatically find an optimal sequence of operations to resize the image by using dynamic programming or greedy algorithm. We also extend our algorithm to indirect image resizing which can protect the aspect ratio of the dominant object in an image.

The reaction mechanisms of intermolecular cleavage reaction of N-（2-hydroxyphenyl）-phthalamic acid were studied via the density functional theory（DFT）. All geometries of the reactant, transition states, and products were optimized at the B3LYP/6-31G（d, p） level. Vibration analysis was carried out to confirm its identity as transitions＇ structure, and the intrinsic reaction coordinate method（IRC） was used to search the minimum energy path. Two possible reaction channels are reported in this article. The calculated results indicate that O-cyclization reaction channel has the lower activation barrier, and therefore, it occurs more easier than the other.

Prostate cancer is one of the most common malignancies in men. Previous research has determined that androgen deprivation therapy （ADT） may be accompanied by an unfavourable metabolic profile. In this prospective study, 133 men were recruited, including 46 prostate cancer patients who had undergone bilateral orchiectomy and been on flutamide （the ADT group）, 37 men with prostate cancer who had undergone radical prostatectomy （the non-ADT group） and 50 normal control subjects （the control group）. All subjects were followed for at least 12 months. From baseline to 3 months, men in the ADT group had increased levels of fasting serum insulin and low-density lipoprotein compared to the other two groups （P〈0.05）. No obvious changes were found in the other parameters （P〉0.05）. After 12 months, men in the ADT group had increased levels of waist circumference, fasting serum insulin and glucose, total cholesterol, high-density lipoprotein and low-density lipoprotein compared to the other two groups （P〈0.05）. Additionally, the morbidity rate of metabolic syndrome in the ADT group was higher （P〈0.05） compared to the other two groups. ADT through surgical castration for men with prostate cancer may be associated with unfavourable metabolic changes. The benefits of the therapy should be balanced prudently against these risks.

自"一带一路"倡议提出以来,中国与沿线国家之间技术创新要素加速流动,对中国创新发展产生重要影响。本文采用2008-2018年地级市面板数据,基于多期双重差分模型,考察"一带一路"倡议背景下中欧班列开通对区域创新效率的影响效应。研究显示:中欧班列开通对区域创新效率具有积极效应,平均提升了9.81%;区位与经济异质性检验发现,区域创新效率提升在中部和西部地区更为显著,且集中在大型城市、中型城市和非资源型城市;机制检验发现,中欧班列开通通过城市创新效应、产业结构效应和资源再配置效应等渠道推动区域创新效率提升;拓展性检验发展,中欧班列开通并未引致开通地区与周边地区的创新资源虹吸效应,而且中欧班列开通对省内地区和省外邻近地区产生广泛的创新效率溢出效应。本文揭示了中欧班列开通对区域创新效率的影响机制,对于深化"一带一路"倡议背景下基础设施互联互通,构建"双循环"新发展格局具有一定现实意义。

BACKGROUND: Patients with short bowel syndrome may require combined liver and intestinal transplantation due to total parenteral nutrition(TPN)-related liver damage. We report combined liver and intestinal allotransplantation as a non-composite technique in a patient in China. METHODS: During the operation, a 380 cm long intestine was transplanted with systemic drainage and aortic inflow, while the liver graft was placed in a piggyback fashion. Warm ischemic time of the donor graft was 2 minutes and 30 seconds, and cold ischemic time for intestinal and the liver graft was 6 hours and 40 minutes and 8 hours and 7 minutes, respectively. Immunosuppressants used after operation included tacrolimus, methylprednisolone, mycophenolate mofetil and Zenapax. RESULTS: The recipient recovered with no evidence of rejection and was kept well on tube feeding. Eventually, he died of massive hemorrhage of the thoracic cavity on day 210 after transplantation. CONCLUSION: The non-composite combined liver and intestinal allotransplantation is superior to composite technique in adult patients, particularly those who have had abdominal infection or repeated abdominal operations.
