2d quantitative structure activity relationship modeling of methylphenidate analogues using algorithm and partial least square regression
… of molecular conformation. A genetic algorithm - partial least squares (GA-PLS) approach was used to identify the molecular descriptors that correlate to the biological activity (binding affinity) of a set of 80 methylphenidate analogues and to construct a predictive model. The GA code was …

Development of mass spectrometry based technologies for quantitative cell signaling phosphoproteomics : the epidermal growth factor receptor family as a model system
… different combinations of EGFR family members. Partial least square regression (PLSR) analysis of our data identified combination of signals strongly correlating with cellular proliferation and migration.

Geographic classification of wines using Vis-NIR spectroscopy
… Australia, New Zealand and Europe. Discriminant partial least square regression (DPLS) and linear discriminant analysis (LDA) based on PCA scores were used to perform classification. Over 90% of the Tempranillo wines were correctly classified according to their geographical region using both DPLS …

Systematic analysis of the role of differential expression of microRNAs associated with cell death decisions
… as a function of microRNA expression using partial least square regression (PLSR). Differential expression analysis was performed to identify relevant microRNAs from the conditions most highly associated to cell death. Global microRNA expression one hour after the second cytokine treatment …

Understanding methods for internal and external preference mapping and clustering in sensory analysis
… analysis, generalized procrustes analysis and partial least square regression utilizing statistical software programs of SAS, Unscrambler, Senstools and XLSTAT. Moreover, the homogeneousness of consumer data were investigated through hierarchical cluster analysis (McQuitty’s similarity …

Characterisation of freeze dried amino acids and gelatin based rapidly Disintegrating tablets
… was estimated using calibration model built from partial least square regression (PLSR). The increased concentration of alanine to 50%w/w and 70% w/w in freeze dried gelatin matrix showed an estimated degree of crystallinity to be ~62% and ~72% (± 16%) respectively. Similarly the degree of …

Development of a continuous flow microreactor for chemical synthesis with in-line catalysis, heating and detection
… using Raman spectra was achieved using partial least square regression (PLSR) which gave results within ±10% to those obtained using the GC-MS method. Using the flow system with in-line Raman analysis, the reaction was optimised and kinetic studies were performed. For the reaction …

Investigating aquaphotomics for fruit quality assessment
… The calibration models were developed using partial least square regression (PLSR) and multiple linear regression to estimate quality attributes. The NIR spectrum of fruit is affected by temperature. Therefore, a calibration equation developed at one fixed temperature cannot reliably predict …

Determination of fertility rating (FR) in the 3-PG model for loblolly pine (Pinus taeda L.) plantations in the southeastern United States
… yet evaluating soil fertility remains one of the least understood aspects of forest science. Phytocentric and geocenctric approaches were used to assess soil fertility in loblolly pine plantations throughout their geographic range in the United States. The model to assess soil fertility using a …

The terrestrial carbon cycle in transition: tracking changes using novel tracers on multiple timescales
… To examine total organic carbon concentration; a partial-least square regression (PLSR) model was produced using Fourier transform infrared spectroscopy (FTIRS) data vs conventionally measured TOC of 141 sediment samples from 13 lakes, resulting in strong positive correlation (R² =0.88). The …
