The effective sample size for multivariate spatial processes with an application to soil contamination
(2021)
Effective sample size accounts for the equivalent number of independent observations contained in a sample of correlated data. This notion has been widely studied in the context of univariate spatial variables. In that ...
Assessing the effective sample size for large spatial datasets: A block likelihood approach
(2021)
The development of new techniques for sample size reduction has attracted growing interest in recent decades. Recent findings allow us to quantify the amount of duplicated information within a sample of spatial data through ...
Effects of sampling completeness on the structure of plant-pollinator networks
(Wiley, 2012)
Plant-animal interaction networks provide important information on community organization. One of the most critical assumptions of network analysis is that the observed interaction patterns constitute an adequate sample ...
Chelating agent effects in the synthesis of mesoscopic-size superconducting particles
(Springer, 2008-05-01)
Several routes and procedures have been used in these last years as an effort to achieve single-phase mesoscopic-size superconducting samples. In this paper, the effects of using citric acid (CA), tartaric acid (TA) and ...
Particle size effect on abrasion resistance of mottled cast iron with different retained austenite contents
(ELSEVIER SCIENCE SA, 2009)
Effects of particle abrasive sizes on wear resistance of mottled cast iron with different retained austenite contents were studied. Abrasive wear tests using a pin test on alumina paper were carried out, using abrasive ...
Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
Quantum size effect and visible light activity of anatase nanosheet quantum dots
(Journal of Photochemistry and Photobiology a Chemistry, 2020)
The Quality of Reporting of Measures of Precision in Animal Experiments in Implant Dentistry: A Methodological Study
(Quintessence Publishing, 2016)
Purpose: Information on precision of treatment-effect estimates is pivotal for understanding research findings. In animal experiments, which provide important information for supporting clinical trials in implant dentistry, ...
