Anomalous Negative Fluorescence Anisotropy in Yellow Fluorescent Protein (YFP 10C):Quantitative Analysis of FRET in YFP Dimers
Alzheimer's disease Amyloid beta 40 peptide Human serum albumin Circular dichroism Dissociation constant alpha-Helix
2016/5/25
Yellow fluorescent protein (YFP) is widely used as a genetically encoded fluorescent marker in biology. In the course of a comprehensive study of this protein, we observed an unusual, negative fluores...
Quantitative Analysis of Supported Membrane Composition Using the NanoSIMS
lipid bilayer SIMS NanoSIMS mixture gradient compositional analysis
2016/5/24
We have improved methods reported earlier [1] for sample preparation, imaging and quantifying components in supported lipid bilayers using high-resolution secondary ion mass spectrometry performed wit...
Quantitative analysis of the 1981 and 2001 Etna flank eruptions: a contribution for future hazard evaluation and mitigation
flank eruptions future hazard evaluation and mitigation
2015/8/27
Lava flows produced during Etna flank eruptions represent severe hazards for the nearby inhabited areas, which can be protected by adopting prompt mitigation actions, such as the building of diversion...
Derivation and quantitative analysis of the differential self-interrogation Feynman-alpha method
Derivation quantitative analysis differential self-interrogation Feynman-alpha
2011/7/20
A stochastic theory for a branching process in a neutron population with two energy levels is used to assess the applicability of the differential self-interrogation Feynman-alpha method by numericall...
Quantitative analysis of the dripping and jetting regimes in co-flowing capillary jets
Quantitative analysis jetting regimes in co-flowing capillary jets
2010/11/16
We study a liquid jet that breaks up into drops in an external co-flowing liquid inside a confining microfluidic geometry. The jet breakup can occur right after the nozzle in a phenomenon named drippi...
A Framework for Quantitative Analysis of Cascades on Networks
Quantitative Analysis Cascades on Networks
2010/11/18
How does information flow in online social networks? How does the structure and size of the information cascade evolve in time? How can we efficiently mine the information contained in cascade dynami...

Quantitative Analysis Point-Centered Quarter Method
2010/11/15
This document is an introduction to the use of the point-centered quarter method. It briefly outlines its history, its methodology, and some of the practical issues and modifications that inevitably ...
On-line Vapor-Phase Generation Followed by Fourier-Transform Infrared Spectrometry for the Quantitative Analysis of Water-Soluble Penicillin G in Pharmaceutical Formulations
Vapor-Phase Fourier-Transform Infrared Spectrometry Quantitative Analysis Water-Soluble Penicillin G Pharmaceutical
2010/9/20
The combination of vapor-phase generation (VPG) and Fourier-transform infrared (FTIR) spectrometry was performed as an alternative analytical technique for the determination of water-soluble penicilli...
Quantitative analysis of randomness exhibited by river channels using chaos game technique:Mississippi,Amazon,Sava and Danube case studies
Quantitative analysis river channels chaos game technique
2009/10/30
This paper presents a numerical evaluation of the randomness which can be observed in the geometry of major river channels. The method used is based upon that of generating a Sierpinski triangle via t...
Uncertainty in river discharge observations：a quantitative analysis
river discharge quantitative analysis
2009/7/22
This study proposes a framework for analysing and quantifying the uncertainty of river flow data. Such uncertainty is often considered to be negligible with respect to other approximations affecting h...
A quantitative analysis of grid-related systematic errors in oxidising capacity and ozone production rates in chemistry transport models
grid-related systematic errors oxidising capacity ozone production rates chemistry transport models
2009/3/5
Limited resolution in chemistry transport models (CTMs) is necessarily associated with systematic errors in the calculated chemistry, due to the artificial mixing of species on the scale of the model ...

摘要
为了定量检测 b 地中海贫血(b 地贫)的 a、b 和γ珠蛋白基因表达水平， 提取正常成人对照组、正常胎儿对照组和b 地贫患者组组成的样本 DNA，采用反向点杂交法（RDB）分析b 地贫各种突变类型；提取样本RNA用于进行针对a、b 和γ珠蛋白基因的荧光实时定量RT-PCR（FQ RT-PCR）。根据FQ RT-PCR原理，设计合成分别对应于a、b 和γ珠蛋白基因的3对引物和3条荧光探针，...
Quantitatively determining the sources of dune sand is one of the problems necessarily and urgently to be solved in aeolian landforms and desertification research. Based on the granulometr...
Quantitative analysis of X-band weather radar attenuation correction accuracy
Quantitative analysis X-band weather radar attenuation correction accuracy
2009/12/29
At short wavelengths, especially C-, X-, and K-band, weather radar signals are attenuated by the precipitation along their paths. This constitutes a major source of error for radar rainfall estimation...
