TLDR
PLS-regression (PLSR) as mentioned in this paper is the PLS approach in its simplest, and in chemistry and technology, most used form (two-block predictive PLS) is a method for relating two data matrices, X and Y, by a linear multivariate model.About:

Determination of flash point and cetane index in diesel using distillation curves and multivariate calibration
TL;DR: Partial least squares regression (PLS) was used to predict flash point and cetane index of diesel using distillation curves (ASTM-D86) as mentioned in this paper, which has two advantages: low cost and easy implementation.

Rapid estimation of soil cation exchange capacity through sensor data fusion of portable XRF spectrometry and Vis-NIR spectroscopy
Mengxue Wan,Mengxue Wan,Wenyou Hu,Mingkai Qu,Weidong Li,Chuanrong Zhang,Junfeng Kang,Yongsheng Hong,Yong Chen,Biao Huang +9 more
TL;DR: Wang et al. as mentioned in this paper examined the potential of the fusing data from PXRF and Vis-NIR to predict soil CEC for 572 soil samples from Yunnan Province, China.

Ethanol production and maximum cell growth are highly correlated with membrane lipid composition during fermentation as determined by lipidomic analysis of 22 saccharomyces cerevisiae strains
Clark M. Henderson,Michelle Lozada-Contreras,Vladimir Jiranek,Marjorie L. Longo,David E. Block +4 more
TL;DR: Yeast strains that achieved the highest cell densities and ethanol concentrations were positively correlated with phosphatidylcholine species similar to those known to decrease the perturbing effects of ethanol in model membrane systems, an indicator of strain ethanol tolerance.

Trace element composition of iron oxides from IOCG and IOA deposits: relationship to hydrothermal alteration and deposit subtypes
Xiao-Wen Huang,Xiao-Wen Huang,Emilie Boutroy,Sheida Makvandi,Georges Beaudoin,Louise Corriveau,Anthony Franco De Toni +6 more
TL;DR: Trace element compositions of magnetite and hematite from 16 well-studied iron oxide-copper-gold (IOCG) and iron oxide apatite (IOA) deposits, combined with partial least squares-discriminant analysis (PLS-DA), were used to investigate the factors controlling the iron oxide chemistry and the links between the chemical composition of iron oxides and hydrothermal processes, as divided by alteration types and IOCG and IOA deposit subtypes.

How does macroinvertebrate taxonomic resolution influence ecohydrological relationships in riverine ecosystems
Wendy A. Monk,Wendy A. Monk,Paul J. Wood,David M. Hannah,Chris A. Extence,Richard P. Chadd,Michael J. Dunbar +6 more
TL;DR: It is concluded that there is a growing need to resolve faunal data to species level to adequately fulfil operational and legislative obligations for river management and conservation purposes.

A Leisurely Look at the Bootstrap, the Jackknife, and Cross-Validation
Bradley Efron,Gail Gong +1 more
TL;DR: This paper reviewed the nonparametric estimation of statistical error, mainly the bias and standard error of an estimator, or the error rate of a prediction rule, at a relaxed mathematical level, omitting most proofs, regularity conditions and technical details.
