The GPS-derived TEC has proved to be a robust characteristic representing well the state of the Earth's ionosphere-plasmasphere system during both quiet and disturbed geomagnetic conditions. Successfully forecasting the TEC value can prove invaluable when trying to improve the communications, navigation, and surveying practices. Presented is a new forecasting method based on auto-correlation analysis and consisting of two major parts - first, extrapolation of the TEC monthly medians using Fourier series approximation, and second, geomagnetically-correlated forecast of the TEC relative deviations of from its median value. Preliminary tests show a good agreement between measured and predicted median values. Presented are also important investigations related to the short-term forecast.
Isotopic correlation analysis is believed to make possible quick and accurate determinations of nuclear fuel parameters for
reactor operation, reprocessing, fuel management and nuclear safeguards. Correlation dependencies have been found between
ratios of fission products on the one hand and isotope ratios of the heavy elements on the other hand. The use of the154Eu/155Eu ratio in correlation analysis was proposed by SMULEK. The scope of useful applications of this isotopic ratio has been
further investigated. A quick and time-saving method to measure the154Eu/155Eu ratio has been elaborated. The atomic ratios have been found by internal calibration using the computer programme ABSINT.
Beside this the atomic ratios of154Eu/155Eu as a function of nuclear fuel burn-up have been calculated using the computer programme ISOTOP.
The correlation between the154Eu/155Eu ratio and nuclear fuel burn-up is best approximated by a quadratic function. Up to a burn-up of 1% fima a linear function
can be used.
Four cases of citation histories of highly cited related papers from the field of chemical correlation analysis indicate that authors have been citing preferably fashionable, but less relevant references.

A Nonlinear Canonical CorrelationAnalysis of Weekly Trip Chaining
The experimental material comprised three crosses, namely Cocorit 71 × A-9-30-1, HI 8062 × JNK-4W-128 and Raj 911 × DWL 5002, generated from six diverse parents. Twelve populations of each of these three crosses revealed that sufficient genetic variation was recorded among generations for all the traits in three crosses. The results of a correlation study demonstrated that the grain yield per plant was significantly and positively associated with peduncle area and flag leaf area in the cross Cocorit 71 × A-9-30-1. However, the spike area had poor correlation with grain yield. In the cross HI 8062 × JNK-4W-128, grain yield per plant was positively associated with peduncle area and spike area, whereas flag leaf area showed a positive but weak association with grain yield. In the cross Raj 911 × DWL 5002, grain yield per plant was positively associated with all three physiological traits studied, indicating that improvement in grain yield may be made by these traits in this material. Peduncle area appeared to be the most important trait in the present study because of its association with grain yield in all three crosses. Although flag leaf area and spike area showed a positive association with grain yield in all three crosses, their relative magnitudes and significance changed from one cross to the other. Correlation studies revealed that selection for peduncle area would lead to high yield in durum wheat. However, due consideration should also be given to flag leaf area and spike area during the selection of plants for further tangible advances in grain yield in durum owing to their positive association with grain yield.
Beginning from the premise that research competitiveness at the university level is the starting point for national competitiveness
as a whole, this paper analyzes the correlation between university research-related performance and the scholarly or academic
resources available through a country’s library system. An analysis of this correlation from two different angles — a macroscopic
approach considering universities in OECD nations and a microscopic approach focusing only upon universities in Korea — found
that there is indeed a significant correlation between university research performance and the scholarly information available
at libraries. A regression analysis of the two approaches also found that the more journal titles subscribed to by university
libraries and the higher their budget for materials, the greater the contribution university libraries make to university
research competitiveness in Korea as well as other OECD countries. In this light, in order for Korea to reach a level of research
competitiveness comparable to other OECD members, policies need to be created that will effectively increase the number of
journals subscribed to by university libraries.
High molecular weight (HMW) glutenin subunits and baking quality-related traits were studied in 50 Indian wheat landraces. Scoring of germplasm based on electrophoresis patterns using the Payne method showed that the quality scores varied from 4 to 8. Based on this scoring, 13 cultivars were ranked as superior. Cluster analysis based on electrophoresis patterns and Jaccard similarity criteria divided the cultivars into five groups, with 13 cultivars in the first cluster. There was no similarity between the grouping pattern based on HMW glutenin sub-units and quality-related traits. In the present study, the quality of the flour of six wheat varieties was weak, so these varieties were only suitable for biscuit making. The flour of 31 wheat varieties showed medium strength. The remaining 13 wheat varieties had strong flour. Considering the great variation observed for quality-related traits and HMW glutenin sub-units, it can be concluded that these cultivars are potential sources of desirable quality traits for use in bread wheat breeding programmes to improve bread-making quality.
