5Multifractal modelling and spectrum analysis: Methods and applications to gamma ray spectrometer data from southwestern Nova Scotia, Canada显示文摘Multifractal spectrum, autocorrelation/semivariogram and power spectrum are three dif- ferent functions characterizing a field or measure from different aspects. These functions are interre- lated in such that the autocorrelation/semivariogram and power spectrum are related to the low order statistical moments (0 to 2 nd) which may determine the local multifractality (τ ″(1)) of a multifractal measure. A better understanding of the interrelationships among these three functions is important because, on one hand, the multifractal modelling characterizes a multifractal measure in a more de- tailed manner since it involves moments of all orders. On the other hand, the commonly used semivariogram and power spectrum functions can be used as alternatives to study the dominant mul- tifractal properties around the mean measure. Moreover, semivariogram and power-spectrum func- tions provide spatial and spectral information, which is highly valued in geological applications. A new fractal relation found between area and power-spectrum will be useful for investigation of new meth- ods of spatial-spectral analysis for pattern recognition, anomaly separation, classification, etc. These results have been demonstrated with the case study of modelling gamma ray spectrometer data from the mineral district, southwestern Nova Scotia, Canada. The results have shown that the values of uranium (U), thorium (Th) and potassium (K) may possess monofractal properties whereas the ratios of these values show high multifractality. The values of the ratios U/K and U/Th show relatively large variances and may provide more information for distinguishing the distinct phases of the granites, country rocks as well as possible gold mineralization-associated regional hydrothermal alteration zones. In addition, the power spectra for U, Th, K, U/Th and U/K consistently show two distinct power-law relationships for two ranges of wave number 12≤ω ≤160 km and 0≤ω ≤12 km. These properties might provide useful thresholds for separating the power-spectrum values into two types of patterns to reflect different influences of possible geological processes such as hydrothermal altera- tion in the study area.CHENG Qiuming1,2 1.

9The complexities underlying age-related macular degeneration: could amyloid beta play an important role?显示文摘Age-related macular degeneration(AMD) causes irreversible loss of central vision for which there is no effective treatment. Incipient pathology is thought to occur in the retina for many years before AMD manifests from midlife onwards to affect a large proportion of the elderly. Although genetic as well as non-genetic/environmental risks are recognized, its complex aetiology makes it difficult to identify susceptibility, or indeed what type of AMD develops or how quickly it progresses in different individuals. Here we summarize the literature describing how the Alzheimer's-linked amyloid beta(Aβ) group of misfolding proteins accumulate in the retina. The discovery of this key driver of Alzheimer's disease in the senescent retina was unexpected and surprising, enabling an altogether different perspective of AMD. We argue that Aβ fundamentally differs from other substances which accumulate in the ageing retina, and discuss our latest findings from a mouse model in which physiological amounts of Aβ were subretinally-injected to recapitulate salient features of early AMD within a short period. Our discoveries as well as those of others suggest the pattern of Aβ accumulation and pathology in donor aged/AMD tissues are closely reproduced in mice, including late-stage AMD phenotypes, which makes them highly attractive to study dynamic aspects of Aβ-mediated retinopathy. Furthermore, we discuss our findings revealing how Aβ behaves at single-cell resolution, and consider the long-term implications for neuroretinal function. We propose Aβ as a key element in switching to a diseased retinal phenotype, which is now being used as a biomarker for latestage AMD.Savannah A.

13不育男性与正常供体内及两者间精液参数的变异显示文摘Objective: To determine within-and between-subject variation of semen parameters in infertile and normal men. Design: Retrospective analysis of 74 infertile men and 65 normal men producing five or more ejaculates each. Setting: Clinical andrology laboratory. Subject(s): Men presenting to an infertility clinic for semen analysis and normal men providing donor semen for cryopreservation. Intervention(s): None. Main Outcome Measure(s): Within-subject coefficients of variation (CVw) and between-subject coefficients of variation (CVb), calculated for sperm count, motility, and velocity, semen volume, and motility and velocity after cryopreservation. Result(s): The number of ejaculates ranged 5-20 in patients (479 total) and 5-136 in donors (2,043 total). Sperm counts, motility, and velocity were statistically greater in donors, whereas semen volume was significantly greater in patients. The CVw in patients and donors was greatest in sperm counts (54.2%and 45.8%, respectively)-and lowest in velocity (20.1%and 19.9%, respectively). The CVb in patients and donors was markedly higher than CVw for all parameters in both patients and donors. The CVw was lower, and the CVb was higher, in donors compared with patients. The CVw was not affected by age of the individual or abstinence period. Cryopreservation resulted in a marked increase in variability. Intraclass correlations indicated that a minimum of three semen samples were required to achieve reliability. Conclusion(s): These data indicate large within-and between-subject variation in sperm parameters, especially sperm count, in both patients and healthy donors, and further substantiate the need for measurement of multiple ejaculates before characterizing a man as normal or infertile.Keel B.A. 李跃萍 2006世界核心医学期刊文摘(妇产科学分册)2006,0,4:3

15Modified High-order Upwind Method for Convection Diffusion Equation显示文摘Abstract In this paper, we study the high-order upwind finite difference method for steady convection-diffusionproblems. Based on the conservative convection-diffusion equation, a high-order upwind finite difference schemeon nonuniform rectangular partition for convection-diffusion equation is proposed. The proposed scheme is inconversation form, satisfies maximum value principle and has second-order error estimates in discrete H^1 norm.To illustrate our conclusion, several numerical examples are given.Wei-dong ZHAO, Dong LIANGSchool of Mathematics and System Sciences, Shandong University, Jinan 250100, ChinaDepartment of Mathematics and Statistics, York University, 4700 Keele Street, Toronto, Ontario, M3J 1P3, Canada 2002Acta Mathematicae Applicatae Sinica2002,18,1:2
16有症状门诊病人深静脉血栓形成的诊断,临床评价和D-二聚体分析可能减少对影像学诊断的需要显示文摘深静脉血栓形成(DVT)的年发病率为48~182/10万,一般估计为1/1000.DVT病死率为1%~5%,发病率和病死率与年龄密切相关.慢性疼痛、肿胀、偶尔腿部皮肤溃疡等血栓后综合征见于1/3发生过DVT的患者.血栓后综合征可出现较早,也可迟至10年才出现,总的发病率为2年23%,5年28%.患者如使用弹力加压袜至少2年以上,腿部病变的发生率可减半.对DVT及其后果警惕性的提高使得要做检查的患者数量增加,其中许多人属于低风险性,反映在检查报告中DVT阳性诊断率下降.Keeling DM Mackie IJ Moody A Watson HG 吴淑燕 王兆钺 2004国外医学(输血及血液学分册)2004,27,5:2
17Ionic conductivity anomaly in soil cover——Exploration of blind mineralization beneath regolith cover显示文摘This paper briefly describes the formation of ionic conductivity anomalies in soil cover, and the characteristics of ionic composition that forms conductivity anomalies, based on the theory of geoelectrochemical halo. Based on some practical results of soluble ions in soil cover and soil conductivity derived from a number of mining areas of both China and overseas, here we present the correlation of a conductivity anomaly with the ionic composition and establish a model for the formation of conductivity anomalies in soil cover. The results indicate that the formation of a conductivity anomaly is not a simple transformation of a secondary geochemical anomaly. A conductivity anomaly is formed as the result of electrochemical and chemical processes, by transformation of orebody into various ionic haloes through four physicochemical processes: 1) dissolution of the orebody, 2) migration of dissolved matter, 3) conversion of matter near the surface, and 4) the formation of ionic conductivity anomalies. The conductivity anomaly, as a physical parameter, essentially represents the integration of various geochemical compositions and is controlled by a set of particular ionic groups.KEELING John L. 2010Science China Earth Sciences2010,53,5:2
