Data Analysis and Results

Kounaves SP, HechtMH, Kapit J etal(2010) Wet Chemistry experiments on the 2007 Phoenix Mars Scout Lander mission Data analysis and results. J Geophys Res 115 EOOE10. doi 10. 1029/2009JE003424... 

A typical PCS instmment consists of following components a light source, a set of optical elements to condition and transmit the beam, a sample module, second set of optical elements to collect the scattered light, a detection system, a correlator, and a computer for experiment control, data analysis, and result output [6]. 

The net result, at any rate, is that there has not been a strong need, apparently, to develop alternative systems and/or these systems have not gained wide popularity and use within the industrial and academic communities in the field. When this has been attempted, no clear wirmer has emerged when consideration was given to advantages and disadvantages of potential alternatives [6] and to an increase in the complexity of data analysis and automation. 

Since the flowing-afterglow method is quite well established, a brief review of the basic features of this technique should be sufficient. The experiments of Gougousi et al.46 on H3 recombination and those of Adams et al.18 and of Smith and Spanel24 used nearly the same experimental method, but there are significant differences in the data analysis and in the interpretation of the results. 

Automation and data collection from complex laboratory equipment have been accomplished. The result of this effort has been more efficient use of the researcher s time, Improved data analysis and the capability to easily conduct lengthy experiments without personnel being present. 

Data analysis and interpretation (i.e. extrapolation to the target patient population) Different formulas are used to correct duration of the QT interval for heart rate some formulas may overcorrect at high heart rates and undercorrect at low heart rates (e.g. Bazett s formula) consider that with some formulas (e.g. Bazetf s) a QTc increase of 4-5 ms may result from measurement bias Need for an individualized correction formula... 

Fluorescence spectroscopy and its applications to the physical and life sciences have evolved rapidly during the past decade. The increased interest in fluorescence appears to be due to advances in time resolution, methods of data analysis and improved instrumentation. With these advances, it is now practical to perform time-resolved measurements with enough resolution to compare the results with the structural and dynamic features of macromolecules, to probe the structures of proteins, membranes, and nucleic acids, and to acquire two-dimensional microscopic images of chemical or protein distributions in cell cultures. Advances in laser and detector technology have also resulted in renewed interest in fluorescence for clinical and analytical chemistry. 

Sometimes the blind review can throw up data issues that require further evaluation by the data management group with data queries being raised, and these perhaps may result in changes to the database. This sequence of events can cause major headaches and delays in the data analysis and reporting, and so it is important in the planning phase to get the data validation plan correct so that issues are identified and dealt with in an ongoing way. 

The report of results should include data, analysis, and presentation. Specifically, the data report should include the description of the flow of the patients through the study, as well as the number of patients included in each stage of the analysis and/or subgroup examined. The data report should provide distributions (including missing values) of basic demographic characteristics (e.g., sex and age), standard (disease-specific) prognostic...
