Abstract Interfaces for Data Analysis —Component Architecture for Data Analysis Tools

The fast turnover of software technologies,in particular in the domain of in teractivity(covering user interface and visualisation)makes it difficult for a small group of people to produce complete and polished software-tools before the underlying technologies make them obsolete.At the HepVis ‘99 workshop,a working group has been formed to improve the rpoduction of software tools for data analysis in HENP.Beside promoting a distributed development organisation,one goal of the group is to systematically design a set of abstract interfaces based on using modern OO analysis and OO design techniques.An initial domain analysis has come up with several categories(componets)found in typical data analysis tools:historams,Ntuples,Functions,Vectors,Fitter,Plotter,Analyzer and Controller,Special Emphasis was put on reducing the couplings between the categories to a minimum,thus optimising re-use and maintainability of any component individually.The interfaces have been defined in Java and C and implementations exist in the form of libraries and tools using C (Anaphe/Lizard,Openscientist)and Java(Java Analysis Studio),A special implementation aims at accessing the Java Liraries(through their Abstract Interfaces)from C .This paper giver an overview of the architecture and design of the various components for data analysis as discussed in AIDA.     

荧光寿命数据的相量分析及其应用

荧光寿命显微成像技术(fluorescence lifetime imaging microscopy, FLIM)具有特异性强、灵敏度高、可定量测量等优点,被广泛应用于生物医学、材料学等领域的研究.为使FLIM技术更好地适用于高通量数据的快速分析,近年来涌现出多种荧光寿命分析的新算法.其中,相量分析法(phasor analysis, PA)通过将时间域的拟合转化为频率域的直接计算来获得荧光寿命值,与传统的最小二乘拟合法相比,不仅更加简便快速,适用于低光子数情形,而且便于使数据内容可视化和对数据进行聚类分析,因此越来越受到科研人员的青睐.本文详细阐述了相量分析法的基本原理及运用方法,并在此基础上介绍了该方法在细胞代谢状态测量、蛋白质相互作用研究、细胞微环境测量,以及辅助病理诊断和提高超分辨成像分辨率等方面的应用,着重讨论了PA法在这些FLIM应用实例中的优势所在,为相关领域的研究提供有益的参考.最后,对荧光寿命数据的相量分析及其应用的发展方向进行展望.     

Recent results from HERA

After the end of data taking in 2007,the experiments H1 and ZEUS have entered into an intense phase of data analysis.Recent results of this effort on neutral （NC） and charged current （CC） cross sections at high Q 2,the longitudinal structure function F L,inclusive diffraction,heavy flavour production and on searches for glueballs are presented.Also shown are results of a combined analysis on inclusive NC and CC cross sections performed by H1 and ZEUS using HERA-I data.     

氧气传感器的原理及其在不同气体环境中使用的注意事项

在“模拟雷雨条件下氮气和氧气反应的数字化实验探究”中,使用氧气传感器,出现“不降反升”的问题。查阅氧气传感器的型号,经过对其原理进行分析,得出其实质是利用原电池反应。为验证其反应原理,将氧气传感器分别放置在氯气和二氧化氮气体中测量并绘制数值变化曲线,对数值进行分析,提出使用氧气传感器时的注意事项。

Baryon resonance analysis from SAID

We discuss the analysis of data from πN elastic scattering and single pion photo- and electroproduction. The main focus is a study of low-lying non-strange baryon resonances. Here we concentrate on some difficulties associated with resonance identification, in particular the Roper and higher P11 states.     

Color appearance and visual measurements for color samples with gloss effect

We assess the color appearance of the samples with different inks on glossy substrates, five kinds of paper with different gloss levels. The color samples are measured using spectrophotometers under different illuminating/viewing geometries and visually estimated using the psychophysical method of magnitude estimation. The results of the two approaches are compared through the color appearance model of CIECAM02. The experimental data analysis indicates that the 0/45 and 15/0 geometries can be used to describe the two major aspects of gloss effect, the enlargement of color gamut, and the reduction of lightness. The agreement for hue attribute between instrumental measurement and visual assessment is better than those for colorfulness and lightness.     

A detecting method for line-spectrum target based on variance-of-frequency weight

There are highly intensive and stable line-spectrums in the radiated noise of passive target,and different targets have line-spectrums with different frequencies.This paper puts forward Conventional BeamForming(CBF) variance-of-frequency detector,which weights bearing spectrum using the variance of frequency of line spectrum with maximum amplitude in each azimuth. It is able to suppress multi-target interferences effectively,and detect faint signal in the background of strong interferences.What’s more,CBF variance-of-frequency detector needs only three-dimension display,while other line-spectrum detectors require for four-dimension display.The simulation and trial data analysis show that the CBF variance-of-frequency detector is able to detect faint line-spectrum target in the background of the continuous spectrum strong interferences.
