Aortic diameter was the best parameter related to BAV (AUC 0.92) and aortic GLS was best correlated with significant AR (AUC 0.76). AVR was the only outcome observed and its only predictor was indexed LV end-diastolic volume. BAV had impaired LV-GLS values. Aortic GLS was abnormally augmented in BAV patients, which might reflect higher aortic diameters that distorted strain calculations. STE aortic strain is related to AR but does not appear to be a reliable predictor of surgery in BAV patients, at 19 months.This paper deals with the effect of introducing an additional interaction site onto molecular-mechanical models of nitrogen-containing heterocyclic compounds. The introduction of only one additional site next to nitrogen atoms is shown to result in significant improvement of the quality of the models along with negligible slowdown of calculation speed. Concretely, it was proposed to introduce the site inside the aromatic ring at a distance of 0.4 Å from the nitrogen atom center. All the parametrization can be completely automated. The proposed force field allows predicting heats of evaporation of liquids of the compound under investigation with an accuracy of 1 kcal/mol.In the present work, the influence of hybridization on cooperativity between C-H···N hydrogen bonds is theoretically investigated. Here, C2H6, C2H4, and C2H2 are considered as hydrogen bonding donor while NH3, N2H4, N2H2, and N2 act as the hydrogen bonding acceptor. The calculations are performed at MP2/aug-cc-pVTZ level. It is observed that the stability of systems is amplified as C(sp) > C(sp2) > C(sp3) and also N(sp3) > N(sp2) > N(sp). The role of interaction and deformation energies on the stability of the systems is examined. The results indicate the contribution of interaction energy is dominant in all complexes. The strength of C-H···N hydrogen bon
