Exploration of geochemical data with compositional canonical biplots.
Graffelman J, Pawlowsky-Glahn V, Egozcue JJ, Buccianti A. Graffelman J, et al. J Geochem Explor. 2018 Nov;194:120-133. doi: 10.1016/j.gexplo.2018.07.014. Epub 2018 Jul 25. J Geochem Explor. 2018. PMID: 33510550 Free PMC article.
The related covariance matrices are structurally singular, and this is efficiently dealt with by using generalized inverses. We develop compositional canonical biplots and detail their properties. The canonical biplots are shown to be powerful tools for discovering …

Physiological consequences of gamma ray irradiation in tall fescue with elimination potential of Epichloe fungal endophyte.
Amirikhah R, Etemadi N, Sabzalian MR, Nikbakht A, Eskandari A. Amirikhah R, et al. Ecotoxicol Environ Saf. 2019 Oct 30;182:109412. doi: 10.1016/j.ecoenv.2019.109412. Epub 2019 Jul 8. Ecotoxicol Environ Saf. 2019. PMID: 31295658
The results also revealed that the persistence and intensity of endophyte were affected after gamma-ray irradiation. The initial percentage of tall fescue seeds infected with the endophyte was 91% in un-irradiated seeds. ...A dramatic reduction in the presence and intensit …

Image quality optimization of narrow detector dental computed tomography for paediatric patients.
Brasil DM, Pauwels R, Coucke W, Haiter-Neto F, Jacobs R. Brasil DM, et al. Dentomaxillofac Radiol. 2019 Jul;48(5):20190032. doi: 10.1259/dmfr.20190032. Epub 2019 Mar 29. Dentomaxillofac Radiol. 2019. PMID: 30864834 Free PMC article.
For technical evaluation, segmentation accuracy, contrast-to-noise ratio and full width at half maximum were measured. Biplot graphs were used to choose representative parameters, from which the best kV was selected for each protocol and evaluation. kV values that had no s …

New Approach to Determine the Activity Concentration Index in Cements, Fly Ashes, and Slags on the Basis of Their Chemical Composition.
Caño A, Suárez-Navarro JA, Puertas F, Fernández-Jiménez A, Alonso MDM. Caño A, et al. Materials (Basel). 2023 Mar 28;16(7):2677. doi: 10.3390/ma16072677. Materials (Basel). 2023. PMID: 37048970 Free PMC article.
For this reason, and taking into account that there is a relationship between the chemical and radiological composition of these building materials, a new approach is proposed to determine the radiological content of these materials from a chemical analysis such as X-ray f …

The use of multivariate PCA dataset in identifying the underlying drivers of critical stressors, looking at global problems through a local lens.
Ryu J, Liu KB, McCloskey TA. Ryu J, et al. Data Brief. 2022 Feb 11;41:107946. doi: 10.1016/j.dib.2022.107946. eCollection 2022 Apr. Data Brief. 2022. PMID: 35242928 Free PMC article.
A sediment core was retrieved using a vibracorer from an intermediate marsh in Lake Salvador, Louisiana, USA. X-ray Fluorescence (XRF) quantified fluvial and marine elemental concentrations (Cl, Sr, Ca, Mn, K, Ti, Fe, Zn, Zr, Br). ...The squared cosine function, which demo …
