2,3,7,8-Substituted polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDD/Fs) and non-ortho-substituted polychlorinated biphenyls (PCBs) account for almost all of the total toxic equivalents (TEQ) in environmental samples. Activated carbon columns are used to fractionate the samples ...
Allometric equations for the invasive vine Dioscorea bulbifera L. in its exotic range in Florida Non-destructive means for estimating Dioscorea bulbifera biomass will help gauge its management efficacy over time. Herein, we developed allometric equatio... BR Min,E Rohrig,PW Tipping,... - 《Invasiv...
It affords unique opportunities for statistical analysis. The variables can be orderly added, subtracted, multiplied, divided. Mean, median, and mode can be calculated using the ratio scale. Ratio scale has unique and useful properties. One such feature is that it allows unit conversions like kilo...
Temporal duration is sufficient to estimate system resilience. Continuous time series of multi-decadal length for some variables are valuable for identifying acceleration of processes (e.g., ice melt; forest dieback), detection of abrupt shifts, and analysis of changing variability and resilience for ...
Neurons, however variable, act as non-linear summing integrators, with a decay in potential and a threshold for firing; they spike when excited frequently and strongly enough. Here, we propose a scale-invariant dynamic, where a pair of similar views of the same object are separated by a ...
In the emergency medicine, it is very important to ascertain safety criteria to discharge patients, time to remain in the E.R., and also ascertain the time intervals for discharge/admission. The use of the scores in the emergency medicine, toxicology and other areas of intensive medicine have...
The clear recognition of the correct geometrical model is particularly important for problems involving measurements and distances, both on general methodological grounds and as a means of verifying the empirical significance of the mathematical conclusions. The addition of axioms or hypotheses which are ...
There are important advantages to including reversed items in questionnaires (e.g., control of acquiescence, disruption of nonsubstantive responding, bette... B Weijters,H Baumgartner - 《Journal of Marketing Research》 被引量: 73发表: 2012年 ...
Note that in (F), pairwise comparisons between quadrat, plot, and site levels are non-significant (P > 0.1 for all). Extended Data Fig. 5 The diversity − stability relationships (DSRs) across multiple spatial scales, using sites with ≥ 5 years records (N = 24 ...
It is important for clinical practice to differentiate between conditions displaying similar symptoms via established diagnostic instruments. Applying the LightGBM algorithm in machine learning, we were able to differentiate subjects with ADHD, obesity, problematic gambling, and a control group using all ...
