Abstract

The vertical ionization potentials (IPS) of B2H6 are calculated by means of the ΔESCF procedure, within the scheme of ab initioLCAO-MO-HF-SCF. The basis set used is LEMAO-3G. The scaling factors of the various atomic orbitals for the ground state and for the various hole states are optimized independently. The iteration procedure is specially designed to avoid the changes of the symmetry of the remaining occupied orbitals. The 1 ag (B1s) hole is found to be localized. The vertical IP of the 1 ag electron is calculated to be 196.5 eV, in fair agreement with experimental value. The D2h symmetry is thereby broken and reduced to C2V symmetry. The valence holes are found to be delocalized. The calculated vertical IPS are: 21.781, 16.974, 14.842, 14.389, 13.599, and 12.380 eV for the 2ag, 2b1u, 1b3u, 1b2u, 3ag, and 1b3g electrons, respectively. The agreement with experimental values is much better than the Koopmans' values. All these results are in favor of the concept that the nature of the convelent bond should be considered as a result of the mutual interactions and mutual conditioning between the wave nature of the electronic motion on the one side and the various attractive and repulsive factors on the other side.

Abstract

Backgrounds: Free-wall rupture (FWR) has a high mortality rate. We aimed to find sensitive predictive indicators to identify high-risk FWR patients by exploring the predictive values of neutrophil percentage-to-albumin ratio (NPAR) and monocyte-to-lymphocyte ratio (MLR) on patients with acute myocardial infarction (AMI)., Methods: 76 FWR patients with AMI were collected, and then 228 non-CR patients with AMI were randomly selected (1:3 ratio) in this retrospective study. The independent influencing factors of FWR were evaluated by univariate and multivariate logistic regression analysis. The receiver-operating characteristic (ROC) curve analysis was applied to evaluate the predictive value of NPAR and MLR for FWR., Results: According to the results of multivariate logistic regression analysis, emergency percutaneous coronary intervention (PCI) (OR = 0.27, 95% CI: 0.094-0.751, p = 0.012), angiotensin-converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) treatment (OR = 0.17, 95% CI: 0.044-0.659, p = 0.010), NPAR (OR = 2.69, 95% CI: 1.031-7.044, p = 0.043), and MLR (OR = 5.99, 95% CI: 2.09-17.168, p = 0.001) were the influencing factors of the FWR patients with AMI, independently. Additionally, the NPAR and MLR were the predictors of FWR patients, with AUC of 0.811 and 0.778, respectively (both p < 0.001)., Conclusions: In summary, the emergency PCI and ACEI/ARB treatment were independent protective factors for FWR patients with AMI, while the increase of MLR and NPAR were independent risk factors. What's more, NPAR and MLR are good indicators for predicting FWR., (© 2021 The Authors. Journal of Clinical Laboratory Analysis published by Wiley Periodicals LLC.)
