Theoretical calculation method of hyperbolic rotating thin shell bending problem
Zhongguo Jianchuan YanjiuObjectiveIn order to analyze the bending characteristics of a hyperbolic rotating thin shell, the complex two-dimensional mechanical problem is simplified into a one-dimensional bending problem based on Euler's Bernoulli beam theory.

Psychology &Marketing, EarlyView.ABSTRACT Despite growing interest in vegan products, research examining the motivations, underlying psychological processes, and boundary conditions that drive consumer preference for vegan products remains limited. Drawing on theories of temporal self and appraisal theory, we find that an immediate message appeal (e.g., animal welfare), as compared to

Mathematical model of rigid body motion for the research of the “Dzhanibekov's effect”
Propulsion and Power ResearchAn alternative set of angles for determining the position of a rigid body, instead of Euler angles, is proposed. These angles were used to model the motion of a rigid body (rotor) rotating around a horizontal axis.

Analytical Solutions for the Cardiac Extracellular‐Membrane‐Intracellular Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The cardiac extracellular‐membrane‐intracellular (EMI) model is a novel mathematical framework for cardiac electrophysiology simulations. The cardiac EMI model provides a more detailed description of the heart's electrical activity compared to traditional monodomain and bidomain models, potentially making it better‐suited for understanding the

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The planar and radial thermal free jets for forced convection of a non‐Newtonian power‐law fluid are investigated. The thermal diffusivity is dependent on the shear‐rate and is not a constant. The flow in planar and radial thermal free jets is governed by the momentum, continuity and energy balance equations. In the stream‐function formulation,
