Moreover, the mechanisms of injection/suction and stretching/shrining have been analyzed individually and jointly for such flows. The present simulation has generalized the steady flow models of viscous thin film over porous, stretching and shrinking sheet of nonuniform thickness. We explored new and multiple dimensions of classical problems of thin film flow and analyzed it. Here, we categorically emphasized on the steady nature and kinds of injection (suction) and moving velocities of the sheet, whereas, steady form and variable size of the sheet are also taken into account. We formed different variables and investigated nonlinear cases of steady nature and checked different options for the two components of velocity, defined at the surface of sheet, variable sizes of the thin film and that of sheet. By analyzing all possible cases, we identified exact similarities that allowed the system of partial differential equations and boundary conditions to be precisely converted into ordinary differential equations based on these new variables. The transformed equation of continuity has two dimensionless parameters, which show that mass can be added/removed to/from the flow regime through two sources i.e. mass can be added/removed to/from the system by <strong>(i)</strong> injection/suction through porous sheet <strong>(ii)</strong> condensation/evaporation into/from the free surface. The system of exact ordinary differential equations is solved by <em><strong>bvp4c</strong></em> technique. Whereas, exact solutions of the system are also found under some restrictions on the parameters value. Besides that the two solutions are exactly matched to each other. Moreover, the present simulations are completely matched with the previously published work of this type for appropriate choices of functions and parameters. Note that the strict behavioral changes in the velocity profiles and skin friction coefficient are observed by changing the sign of parameters.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"73 ","pages":"Article 108260"},"PeriodicalIF":4.4,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In turn, this calls for better understanding of low field regime of Simon effect (the effect is related to the influence of the applied magnetic field on the sound wave velocity in a ferromagnetic crystal). In our work, based on the example of bcc Fe, we propose a refined formula to describe the Simon effect, which contains terms related to dispersion effects associated with exchange stiffness. We compare our analytical solutions with other alternative computational approaches and show that dispersion effects can be significant for the Simon effect and cannot be neglected in the low field regime. As a result, we propose a more accurate analytical formula, which, due to its relative simplicity, can become a convenient tool to estimate the magnitude of the expected magnetic field effect on the sound wave speed propagation in a cubic ferromagnetic crystal, as well as it explains observed deviations from analytically expected results in Simon effect at low magnetic field.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"73 ","pages":"Article 108264"},"PeriodicalIF":4.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143886348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A system involving a three-step reaction–diffusion of magneto-Casson fluids has implications for safety management, energy systems, and chemical engineering. Thus, this study examines the thermal runaway phenomenon and its propagation influences on a three-step exothermic reaction of a gravity-driven magneto-Casson fluid, considering convective heat distribution and chemical kinetics along a channel. The study is characterized by an overwhelming temperature rise due to the exothermic heat accumulation, which poses substantial challenges in natural and industrial processes. The interaction between Casson fluid rheological properties, chemical reaction rates, activation energy, and thermal energy with the magnetic field influence is explored. The theoretical model integrating the Casson fluid model is coupled with nonlinear chemical kinetics for a three-step exothermic combustion. Following Newton’s cooling law, the thermal convective exchange at the channel wall is modeled. The dimensionless terms such as the magnetic field intensity, Brinkman number, Grashof number, and Frank-Kamenetskii parameter are utilized to analyze the reaction stability, dissipation, and heat distribution. The study employs a Galerkin weighted residual technique to solve the coupled equations for appropriate parametric sensitivities analysis of the flow characteristics and chemical kinetics on the thermal runaway onset. The main findings revealed that a three-step reaction leads to system complexity, where the reaction intermediate stabilizes and amplifies thermal effects depending on the activation energy. The distribution of temperature in the channel wall provides mitigating runaway risks in industrial applications and gives insights into reaction conditions optimization.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"73 ","pages":"Article 108277"},"PeriodicalIF":4.4,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the formalism of quantum theory is derived from the application of Bayesian probability theory to “fragile” systems, that is, systems that are perturbed by the measurement. Complex Hilbert spaces, non-commuting operators and the trace rule for expectations all arise naturally from the use of linear algebra to solve integral equations involving classical probabilities over hidden variables. The non-fragile limit of the theory, where all measurements are commutative and the theory becomes analogous to classical statistical theory is discussed as well.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"73 ","pages":"Article 108257"},"PeriodicalIF":4.4,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
