The low quality and yield of methane severely hinder the industrial application of straw biogas fermentation, and no effective solution has been found so far. In this study, a novel method was developed when a microbial electrolysis cell(MEC) was coupled with normal anaerobic fermentation to enhance methane yield and purity. The fermentation process achieved a methane purity of more than 85%, which is considerably higher than that of previously published reports. With microbial stimulation and an electric current, the degradation of fibers has been greatly enhanced. The MEC system substantially improved the yield and purity of biogas, bringing a new path to the synthesis of methane by carbon dioxide and hydrogen ions in solution under electron irradiation. Electrochemical index analysis showed extra methane synthesis, due to the external circuit electron transfer. The results of the gas chromatography and solid degradation rate showed that the carbon source of extra methane was CO_(2) produced during normal fermentation and additional volatile solid degradation. These results show that the MEC considerably enhanced the quality and yield of methane in the straw fermentation process, providing insights into normal anaerobic fermentation.

The protein composition of cerebrospinal fluid（CSF） in neural tube defects（NTDs） remains unknown. We investigated the protein composition of CSF from 9 infants with NTDs using isobaric tags for relative and absolute quantitation（iTRAQ）. We identified 568 proteins in the CSF of infants with spina bifida, which is the most common type of NTD. Among these, 18 proteins were associated with neural tube closure in the CSF during human embryonic neurulation and 5 were involved in NTDs. Based on these results, an animal model was further utilized to investigate early serum biomarkers for *** found that the myristoylated alanine-rich C-kinase substrate, Kunitz-type protease inhibitor 2, andapolipoprotein B-100 protein levels were decreased in both embryos and the sera of pregnant Sprague-Dawley rats carrying embryos with NTDs. CSF proteins may be useful in the discovery of potential serum biomarkers for NTDs.

在清中叶以后的巴县,承充坊厢保正须书立顶约、缴纳顶首银,该职可以出租、出卖,甚至合伙承充。这种不同寻常现象的出现,乃是因坊厢保正为帮办各级衙署差务及垫纳军需差费之主体。因这种付出,其职出现顶首银,且获得收取铺户规费之权的状况。坊厢保正具有广泛的营利空间,这吸引许多人投身其中,使该职成为一种与衙门吏役高度相似的职业。在实践中,坊厢保正表现出任职长期化、朋党化等特征。即使至清后期士绅加入坊厢行政组织并成为其中领袖,亦未对保正的实质性权力和利益空间造成根本冲击。

面对高度复杂不确定的外部环境,如何设计政策组合以实现金融业开放、汇率市场化以及国内经济恢复等多重宏观经济目标具有重要的理论与现实意义。为此,本文构建一个具有金融业开放特征的多部门DSGE模型,分析货币政策与宏观审慎政策“双支柱”调控框架应对外部冲击的作用机制与福利效果,并讨论金融业开放水平对汇率制度选择与政策协调搭配的影响。研究表明:为应对外部冲击,中央银行对汇率波动进行管理的力度需要随金融业开放水平的提高而不断加大。同时,金融业开放水平越高,宏观审慎政策逆周期调节银行资产负债表以稳定金融系统乃至整个宏观经济的效果越好。进一步地,在“双支柱”调控框架下,货币政策与宏观审慎政策的协调搭配使用不仅可以带来显著的福利改进,而且能够降低央行对汇率波动的最优管理程度,提高货币政策独立性,从而为实现金融业开放、汇率市场化以及国内经济恢复等多重目标创造条件。

通过构建一个包含双重金融摩擦的NK-DSGE模型,量化分析房企债务违约风险跨部门传递的经济后果、作用机制以及政策应对效果。研究发现,房企债务违约及由此引发的风险跨部门传递将导致经济中出现严重的信贷紧缩与产出衰退,银行部门是房企债务违约冲击传递至实体经济的重要桥梁,其中存贷溢价摩擦起到放大作用。在大规模债务违约触发银行危机的情况下,针对银行资本充足率的逆周期宏观审慎政策更为有效,而货币政策在应对其他常见经济金融冲击时效果更好。针对不同的风险冲击类型,单项政策及政策组合的应对效果存在差异。因此,应对政策的选择与搭配使用需考虑经济体面临的冲击类型。
