The proinflammatory cytokine interleukin-1 has been implicated in host suscep tibility to Helicobacter pylori -associated disease. Recent studies suggest tha t this susceptibility may be under genetic control. It remains to be determined whether the relationship between IL-1 gene polymorphism and gastrointestinal di sease in patients with H. pylori infection is due to the role of IL-1 in determ ining susceptibility to H. pylori infection per se or to the development of dist inct pathological lesions. The aim of this study was to prospectively investigat e the relationship between selected polymorphisms in three of the maj.r IL-1 ge ne family members, seeking associations with H. pylori infection and/or gastric cancer. A total of 559 individuals were studied: 191 patients attending for gast roscopy, 98 with current or previous H. pylori, an additional 79 patients with g astric cancer, and 289 healthy controls. The maj.r novel finding of the study wa s a marked difference in the genotype frequencies for the IL1R1 HinfI SNP in tho se with current or previous evidence of H. pylori compared to those without. (GG , 53 vs 75%; GA, 40 vs 19%; AA, 7 vs 6%; P = 0.0079). The association indicat es an increased risk of H. pylori infection or persistence in those with the IL1 R1 Hinf1 A allele (0.27 vs 0.156; P = 0.009; OR = 2.01). Our results suggest tha t the relationship among IL-1 gene polymorphism, H. pylori, and disease is more complex than initially proposed. More detailed studies of the IL-1 gene cluste r are needed.

哈里森夫妇[Helen Mayer Harrison and newton Harrison]在《温室英国》（2006-9）[Greenhouse Britain]这一多媒体装置中展现了全球暖化在未来会对英国造成的影响。这件以教学为导向的展示作品借助视频动画和多重投影、影像文件、分析文本、声音元素，以及一张大比例的英国地形图，描绘出一个暗淡的未来：水平面上升、风暴潮汹涌、海岸线缩短。“这并不是个好消息，而且情况会越来越糟。动物四处奔逃，植物移往别处。要是平均温度升高两度以上，这一装置就会显示欧洲、亚洲、美洲和亚马逊地区的森林面积减少30％，并引发物种灭绝现象，”牛顿·哈里森在该作品附带的录音中如此说道。在英国，“我们会看到10000平方公里的土地流失掉，让大约220万人无家可归。”。除了指出前景不妙之外，他们还提出创新性的建议：为众多定会流离失所的人修建截水墙、开发环保住宅。据他们所说，格陵兰岛和南极冰盖在本世纪及以后所出现的逐渐消融的现象会让诺福克湖区和泰晤士河口等低洼地带没入水底。

The Super-Halley method is one of the best known third-order iteration for solving nonlnear equations. A newton-like method which is an approximation of this method is studied. Our approach yields a fourth R-order iterative process which is more efficient than its classical predecessor. We establish a newton-Kantorovich-type convergence theorem using a new system of recurrence relations, and give an explicit expression for the a priori error bound of the iteration.

研究食道中蠕动传输的流体力学.对任意的波形和任意的管道长度,建立起流变学流体蠕动传输的数学模型.用粘性流体的Ostwald-de Waele幂定律,描述非newton流体的流动特性.解析公式化模型,详细且精确地给出食物块在食道中蠕动传输相关的一些重要性质.分析中应用了润滑理论,本研究特别适合于Reynolds数不大的情况.将食道看作环形的管道,通过食道壁周期性的收缩来传输食物块.就单个波和周期性收缩一组波的传播,研究与传输过程有关变量的变化,如压力、流速、食物颗粒轨迹以及流量等.局部压力的变化,对流变指数n有着高度的敏感性.研究结果清晰地表明,食物块在食道中蠕动传输时,newton流体或流变学流体构成的连续流体,以组合波传播比大间隔单波传播,传输效率要高得多.

利用扭曲的有质动力，我们给出了驱动产生的扭曲等离子体波。其中我们利用了两束同向传播的拉盖尔-高斯（LG）光，他们分别携带不同的频率和扭曲指数，结果可以得到扭曲的有质动力。LG光一般被认为携带轨道角动量。三维的网格粒子模拟（PIC）模拟被用来证实激光驱动产生扭曲等离子体波。这种扭曲的等离子体波拥有螺旋旋转的电子密度扰动结构。不同于线性流体理论的预测，模拟结果显示一个非线性的旋转电流和静态的轴向磁场。伴随旋转电流的是扭曲等离子体波中携带轨道角动量的粒子。该文中，我们也给出了详细的扭曲等离子体波的理论分析结果。

A proposed framework for accelerating technology traj.ctories in agriculture:a case study in China

Ij.NN International j.int Conference on Neural Networks

作者： S j.Huang S N Koh H K Tang School of Electrical and Electronic Engineering Nanyang Technological University

＜正＞This paper considers the use of newton’s method as a training algorithm for the backpropagation （BP） neural *** it can be proved that newton’s method is convergent in second-order while the most widely used steepest decent method is convergent in first-order[1].This suggests that newton’s method might be a faster algorithm for the BP *** updating equations of the two methods are analyzed in detail to extract some important properties with reference to the error surface *** leads to the proposal of differential error modification to the original newton’s *** common benchmark XOR problem is used to compare the performances of the methods and the results show that the modified newton’s method converges much faster when the error tolerance is small.

Precision agriculture(PA) technologies have great potential for promoting sustainable intensification of food production, ensuring targeted delivery of agricultural inputs, and hence food security and environmental protection. The benefits of PA technologies are applicable across a broad range of agronomic, environmental and rural socio-economic contexts globally. However, farmer and land-manager adoption in low to middle income countries has typically been slower than that observed in more affluent countries. China is currently engaged in the process of agricultural modernisation to ensure food security for its 1.4 billion population and has developed a portfolio of policies designed to improve food security,while simultaneously promoting environmental *** attention has been paid to the reduction of agricultural inputs such as fertilisers and pesticides. The widespread adoption of PA technologies across the Chinese agricultural landscape is central to the success of these policies. However, socio-economic and cultural barriers, farm scale,(in particular the prevalence of smaller family farms) and demographic changes in the rural population,(for example, the movement of younger people to the cities) represent barriers to PA adoption across China. A framework for ensuring an acceptable and accelerated PA technology traj.ctory is proposed which combines systematic understanding of farmer and end-user priorities and preferences for technology design throughout the technology development process, and subsequent end-user requirements for implementation(including demonstration of economic and agronomic benefits, andknowledge transfer). Future research will validate the framework against qualitative and quantitative socioeconomic, cultural and agronomic indicators of successful,or otherwise, PA implementation. The results will provide the evidence upon which to develop further policies regarding how to secure sustainable food production and how best to im
