Chemical Graph Theory for Property Modeling in QSAR and QSPR—Charming QSAR & QSPR [PDF]

open access: yesMathematics, 2020
Quantitative structure-activity relationship (QSAR) and Quantitative structure-property relationship (QSPR) are mathematical models for the prediction of the chemical, physical or biological properties of chemical compounds. Usually, they are based on structural (grounded on fragment contribution) or calculated (centered on QSAR three-dimensional (QSAR-

A QUANTITATIVE STRUCTURE-PROPERTY RELATIONSHIP (QSPR) EVALUATION OF CRITICAL VOLUME OF UNSATURATED HYDROCARBON ALKENES AND ALKYNES USING SIMPLE CONNECTIVITY INDICES

open access: yesReaktor, 2009
A quantitative structure-property relationships (QSPR) was used in this study to relate the critical volume (Vc) of unsaturated hydrocarbons alkenes and alkynes compounds to their molecular structures.

Quoted spreads and trade imbalance dynamics in the European treasury bond market [PDF]

open access: yes, 2010
Using high-frequency transaction data for the three largest European markets (France, Germany and Italy), this paper documents the existence of an asymmetric relationship between market liquidity and trading imbalances: when quoted spreads rise (fall ...

WHIM-3D-QSPR APPROACH FOR PREDICTING AQUEOUS SOLUBILITY OF CHLORINATED HYDROCARBONS

open access: yesIndonesian Journal of Chemistry, 2010
The weighted holistic invariant molecular-three dimensional-quantitative structure property relationship (WHIM-3D-QSPR) approach has been applied to the study of the aqueous solubility (- log Sw) of chlorinated hydrocarbon compounds (CHC's). The obtained

QSAR study for carcinogenicity in a large set of organic compounds [PDF]

open access: yes, 2012
In our continuing efforts to find out acceptable Absorption, Distribution, Metabolization, Elimination and Toxicity (ADMET) properties of organic compounds, we establish linear QSAR models for the carcinogenic potential prediction of 1464 compounds taken

Cross-validation strategies in QSPR modelling of chemical reactions [PDF]

open access: yesSAR and QSAR in Environmental Research, 2021
In this article, we consider cross-validation of the quantitative structure-property relationship models for reactions and show that the conventional k-fold cross-validation (CV) procedure gives an ‘optimistically’ biased assessment of prediction performance.

QSPR Models for Octane Number Prediction [PDF]

open access: yesJournal of Theoretical Chemistry, 2014
Quantitative structure-property relationship (QSPR) is performed as a means to predict octane number of hydrocarbons via correlating properties to parameters calculated from molecular structure; such parameters are molecular mass M, hydration energy EH, boiling point BP, octanol/water distribution coefficient logP, molar refractivity MR, critical ...
