通过多组小尺寸实验多点离散测量烟气成分,对有限的实验数据做Lagrange插值分析,得到相同时刻烟气浓度在不同位置的变化规律以及烟气浓度场随时间的分布。考虑燃烧实验存在随机因素影响,提出用某一组分的质量分数相对值来比较不同实验数据所体现的规律,结果表明烟气浓度沿通道的一维分布受可燃物质量与流通开口高度影响较大。

现有的仿生机器鼠仅可以执行一些基本的仿鼠运动基元(MP),并通过这些基元的刚性组合来形成简单的行为。为了模拟具有高相似性的典型实验鼠行为,本文提出使用概率模型和运动特征对实验鼠的行为进行参数化。首先,对15 个10 min 的实验鼠运动视频片段的分析表明,一只实验鼠在野外通常有6 种典型的行为,且每种行为都包含8 个运动基元的不同组合。本文首先使用softmax 分类器来获得实验鼠的行为-运动分层概率模型。其次,使用静态和动态的运动参数对运动基元组合进行特征化。本文分别使用分层聚类和模糊C均值(FCM)聚类获得静态和动态运动参数的优势值。这些优势值通过二阶傅里叶级数对实验鼠的脊柱关节轨迹进行拟合,并且通过具有两个隐藏层的反向传播(BP)神经网络对关节轨迹进行泛化。最后,将分层概率模型和泛化的关节轨迹分别作为控制策略和指令映射到机器鼠。本文在机器鼠上实现了6 种典型的仿鼠行为,其结果与实验鼠的行为相比显示出高度相似性。

超大型岩浆镍、铂族元素(PGE)硫化物矿床控制了Ni-PGE的资源量,本文根据地幔岩浆事件中Ni、Cu和PGE等在部分熔融、岩浆结晶和硫化物熔离过程的行为,讨论了岩浆Ni-Cu-PGE硫化物矿床的成矿岩浆类型与规模、成矿金属元素聚集的方式、岩浆演化过程中硫饱和度与硫化物液相不混溶的控制因素,探讨了流体对成矿金属的运移聚集作用等。认为地幔大规模的高度部分熔融(即要求高Mg岩浆)促使地幔硫化物及橄榄石中巨量的Ni和PGE进入岩浆,硫化物熔离富集成矿金属形成大型层状(或通道)岩体赋存的超大型Ni-Cu-PGE硫化物矿床;地幔超临界流体可能大范围内搬运聚集大量Ni-PGE金属元素,对岩浆硫化物矿床成矿可能有重要贡献,是小规模岩浆(小岩体)成矿的可能机制。

A ruptured recurrent small bowel gastrointestinal stromal tumour causing hemoperitoneum

Hemoperitoneum is a rare and potentially life-threatening complication of GIST. We reported a 54-year-old man who developed disseminated intra-abdominal recurrence from a previously resected gastrointestinal stromal tumour (GIST) of the small bowel, and the patient presented with hemoperitoneum. Emergent debulking surgery was performed. A high dose imatinib was prescribed. Despite the presence of residual disease, the patient was well clinically 8 months after the operation. Even though, there is no evidence to support the routine use of debulking surgery in the management of GIST. In our patient, disease progression after second line targeted therapy and the absence of alternative treatment options for spontaneous rupture and hemoperitoneum prompted us to treat the patient aggressively. Resection of the ruptured GIST was carried out for control of bleeding and to prevent recurrent bleeding in this patient with good surgical risks. During the treatment decision-making, the patient’s general condition, the risk of surgery and the extent of dissemination were taken into consideration. In this patient who presented with spontaneous rupture of a small intestinal GIST, the novel use of targeted therapy and aggressive surgical treatment produced reasonably good survival outcome.

The gut microbiota is mainly composed of a diverse population of commensal bacterial species and plays a pivotal role in the maintenance of intestinal homeostasis, immune modulation and metabolism. The influence of the gut microbiota on solid organ transplantation has recently been recognized. In fact, several studies indicated that acute and chronic allograft rejection in small bowel transplantation (SBT) is closely associated with the alterations in microbial patterns in the gut. In this review, we focused on the recent findings regarding alterations in the microbiota following SBT and the potential roles of these alterations in the development of acute and chronic allograft rejection. We also reviewed important advances with respect to the interplays between the microbiota and host immune systems in SBT. Furthermore, we explored the potential of the gut microbiota as a microbial marker and/or therapeutic target for the predication and intervention of allograft rejection and chronic dysfunction. Given that current research on the gut microbiota has become increasingly sophisticated and comprehensive, large cohort studies employing metagenomic analysis and multivariate linkage should be designed for the characterization of host–microbe interaction and causality between microbiota alterations and clinical outcomes in SBT. The findings are expected to provide valuable insights into the role of gut microbiota in the development of allograft rejection and other transplant-related complications and introduce novel therapeutic targets and treatment approaches in clinical practice.

Non-small-cell lung cancer (NSCLC) is the most common cause of premature death among the malignant diseases worldwide. The current staging criteria do not fully capture the complexity of this disease. Molecular biology techniques, particularly gene expression microarrays, proteomics, and next-generation sequencing, have recently been developed to facilitate effectively its molecular classification. The underlying etiology, pathogenesis, therapeutics, and prognosis of NSCLC based on an improved molecular classification scheme may promote individualized treatment and improve clinical outcomes. This review focuses on the molecular classification of NSCLC based on gene expression microarray technology reported during the past decade, as well as their applications for improving the diagnosis, staging and treatment of NSCLC, including the discovery of prognostic markers or potential therapeutic targets. We highlight some of the recent studies that may refine the identification of NSCLC subtypes using novel techniques such as epigenetics, proteomics, or deep sequencing.
