在自然界以及人类社会中,绝大多数系统本质上都可以抽象表示为复杂系统,针对当前复杂系统复杂性不断增加这一难题,亟需完善且成熟的复杂系统理论与方法进行建模研究与处理。当前基于图的复杂系统建模方法难以描绘节点间极其复杂的连接以及节点间的高阶关系,同时也难以对复杂系统的智能化感知、决策和控制等行为进行有效刻画。基于此,提出一种融合多智能体与超图的复杂动态系统建模方法,模型从几种不同的演化角度进行动态演化,对复杂动态系统进行了具体的描绘。此模型通过赋予复杂系统中个体智能化特征,进行感知、决策和控制,同时也能够更好地描绘智能体节点间的高阶关系,为复杂系统的智能理论研究提供新思路和新方法。

为研究柴油机活塞环形油腔周向振荡冷却特性,在非惯性坐标系下应用流体体积函数(VOF)多相流模型,对活塞环形油腔振荡冷却进行了瞬态换热研究,得到了环形油腔周向壁面平均换热系数的变化规律,发现壁面平均换热系数的振荡幅度最大的并不是入口冲击的周向10°区域,而是周向20°区域.一个周期内油腔周向区域的壁面平均换热系数整体呈类"对数"减小的趋势,在周向10°~30°区域急剧减小,而后随着远离入口段,其值呈现先增大后减小的变化规律.最后通过两种方法计算活塞温度场并进行对比,发现使用18周向区域的壁面平均换热系数所计算的活塞温度场的顶部温度波动更大,更符合实际情况.

AIM To identify a panel of biomarkers that can distinguish between non-alcoholic fatty liver disease(NAFLD) and non-alcoholic steatohepatitis(NASH), and explore molecular mechanism involved in the process of developing NASH from *** Biomarkers may differ during stages of NAFLD. Urine and blood were obtained from non-diabetic subjects with NAFLD and steatosis, with normal liver function(n = 33), from patients with NASH, with abnormal liver function(n = 45), and from healthy age and sex-matched controls(n = 30). Samples were subjected to metabolomic analysis to identify potential non-invasive biomarkers. Differences in urinary metabolic profiles were analyzed using liquid chromatography tandem mass spectrometry with principal component analysis and partial least squares-discriminate *** Compared with NAFLD patients, patients with NASH had abnormal liver function and high serum lipid concentrations. Urinary metabonomics found differences in 31 metabolites between these two groups, including differences in nucleic acids and amino acids. Pathway analysis based on overlapping metabolites showed that pathways of energy and amino acid metabolism, as well as the pentose phosphate pathway, were closely associated with pathological processes in NAFLD and *** These findings suggested that a panel of biomarkers could distinguish between NAFLD and NASH, and could help to determine the molecular mechanism involved in the process of developing NASH from NAFLD. Urinary biomarkers may be diagnostic in these patients and could be used to assess responses to therapeutic interventions.

相对渗透率是储层评价、油田开发和油藏数值模拟等方面的重要参数,一般通过稳态和非稳态法来获取相对渗透率数据。由于相对渗透率实验所需周期长、成本高,且条件较为苛刻,因此获取相对渗透率数据具有一定难度,而通过现场电阻率测井和室内实验则较为容易获取电阻率数据。本文通过毛细管束模型和阿尔奇电阻率公式,并在引入迂曲度的情况下,推导了一种从电阻率数据中计算相对渗透率数据的新方法。通过文献数据和实验数据对新方法的计算精度进行了验证。结果表明,从电阻率数据得到的水相相对渗透率数据具有很高的精度。在缺少相对渗透率数据的情况下,可以通过新方法从电阻率数据中估算水相相对渗透率。

Radio interferometry significantly improves the resolution of observed images, and the final result also relies heavily on data recovery. The Cotton-Schwab CLEAN(CS-Clean) deconvolution approach is a widely used reconstruction algorithm in the field of radio synthesis imaging. However, parameter tuning for this algorithm has always been a difficult task. Here, its performance is improved by considering some internal characteristics of the data. From a mathematical point of view, a peak signal-to-noise-based(PSNRbased) method was introduced to optimize the step length of the steepest descent method in the recovery process. We also found that the loop gain curve in the new algorithm is a good indicator of parameter *** show that the new algorithm can effectively solve the problem of oscillation for a large fixed loop gain and provides a more robust recovery.
