They selectively inhibit the cyclooxygenase-2 enzyme and are hence used to treat several symptoms of rheumatoid and osteoarthritis. The current study focuses on investigating the interaction of these drugs with some randomly selected polar solvents explicitly. Using the M06-2x/aug-cc-pVDZ level of the theory of DFT, 12 complexes are optimized in the gas phase and their intermolecular interaction studies proceed. After the evaluation of binding energy, frontier molecular orbital analysis, and natural bond orbital analysis are carried out to get an idea of the charge localization and orbital behavior of complexes. Theoretical tools like an atom in molecule (AIM), reduced density gradient (NCI-RDG), independent gradient model based on Hirshfeld partition (IGMH), interaction region indicator (IRI), and core-valence bifurcation (CVB) index are used to identify the intermolecular interaction sites (hydrogen bond) and their strength. EDA analysis gave an idea of how the interaction energy is disseminated into various energy components. All the results obtained show that both drugs effectively interact with DMSO.","PeriodicalId":7219,"journal":{"name":"Advanced Theory and Simulations","volume":"7 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the complexity and uncertainty of complex systems, a large number of rules are often generated when complex models are constructed using the initial BRB. This results in rule base expansion and diminished modeling capability. Therefore, a multi-dimensional rule evaluation framework is first developed in this study. The BRB is effectively screened and optimized, resulting in a significant reduction in the total number of rules and a decrease in model complexity. Furthermore, to ensure the completeness and accuracy of the simplified BRB, a composite rule activation method is introduced for model inference, and a novel evidential reasoning (ER) calculation procedure is designed. Ultimately, a projection covariance matrix adaptation evolution strategy (P-CMA-ES)-based optimization algorithm is proposed to improve the remaining parameters of the model. The optimal model structure is selected using the Akaike information criterion (AIC). In this paper, through case study, the implementation of this method is demonstrated, and the effectiveness of the model in practical applications is validated.","PeriodicalId":7219,"journal":{"name":"Advanced Theory and Simulations","volume":"8 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiphysics simulations using finite element method (FEM), consisting of electromagnetic, thermal, and fluid flow fields are used to analyze both steady-state spatial distribution and transient evolutions of the thermally driven fluid dynamic phenomena in the microscopic field. This study demonstrates that a nano-scale thermal gradient can lead to nm-scale changes in fluid dynamics and on the nano-scale, while such convection does not significantly affect the steady-state temperature distribution, even in the presence of injection flow, but the localized thermal-driven convection will contribute to the flow dynamics to some extent.

Furthermore, the Nucleus independent chemical shift (NICS) descriptor is employed to demarcate the role of aromaticity in dictating the specifics of the said non-covalent interactions as well as the overall spatial architectures. Although, the typical observation is that the N─H····N and the N─H····O hydrogen bonds (HB) are resonance assisted (partially covalent) and ionic respectively, deviation from this trend is also apparent. Moreover, it is found that the conventional notion of resonance assisted HBs in a dimeric structure consisting of aromatic skeletons (i.e., an increase in thearomaticity of the ring containing the HB donor moiety coupled with a concomitant decrease in the aromaticity of the ring containing the HB acceptor atom/group) is not strictly applicable to the nucleobases. The influence of steric factor in the stabilizations associated with the studied HBs is justified via Energy Decomposition Analysis.
