Summary: This paper presents an exact closed-form solution of three-dimensional transient Green's functions at the free surface of a constrained transversely isotropic half-space for an arbitrarily oriented surface point force of Heaviside time variation. The solution highlights the distinct features of body waves and Rayleigh surface wave in displacement components, showcasing the effects of material anisotropy. Additionally, the radial and angular displacements due to horizontal point force exhibit a special disturbance proportional to the inverse square of epicentral distance and varying linearly with time, a feature unique to transversely isotropic materials.

Summary: This study investigates the heat transfer characteristics of Cu-Fe3O4 nanoparticles in water-based Maxwell fluid flow over a cone in a porous medium, taking into account the effects of magnetic field and thermal radiation. The results show that increasing the temperature time relaxation parameter decreases the thermal gradient, while increasing the temperature fractional derivative parameter increases the thermal gradient. Furthermore, adding 1% Cu-Fe3O4 enhances the heat transfer rate, while the presence of a magnetic field decreases the heat transfer rate of the Maxwell fluid.

The obtained solutions, presented in terms of generalized G- and R-functions, satisfy all imposed initial and boundary conditions. Similar solutions for ordinary Maxwell and Newtonian fluids can also be obtained as a limit of the solution for generalized Maxwell fluid.

Summary: The present work investigates the axisymmetric deformation in a thick circular plate with a heat source under void, diffusion, and phase lags impacts using modified couple stress thermoelastic (MCT). New set of governing equations is formulated and solved using Laplace and Hankel transform techniques in dimensionless form and using potential functions. Analytical closed-form solutions for physical quantities such as displacements, temperature field, mass concentration, chemical potential, and volume fraction field are obtained, and numerical techniques are employed to analyze different physical effects. The results provide motivation to study thermal conducting modified couple stress elastic solid under the physical impact of mass diffusion, porosity, and phase lags as a new class of material. This work has significant importance for various deformation and vibration problems in geophysics, material science, engineering, and biothermoelastic materials.

Summary: This study aims to analyze the heat transfer performance of unsteady magnetohydrodynamics (MHD) in hybrid nanofluid and the impact of heat generation/absorption, converting multivariable differential equations with partial derivatives into a specific type of ordinary differential equations through similarity transformations. The results show that increasing nanoparticle concentration and magnetic field increases the coefficient of skin friction, while the inclusion of the heat generation parameter leads to an upward trend in temperature distribution profile, degrading heat transfer performance. Multiple solutions were confirmed, leading to stability analysis to confirm the feasibility of the first solution.

Summary: This study provides a comprehensive assessment of three-dimensional Jeffery fluid flow under the significances of thermal radiation and magnetohydrodynamics. The results revealed that the motion of the Jeffery fluid decreases with increasing porosity term but increases with the rising influence of wall thickness factor. The velocity curve decreases in both x and y directions with the increasing values of Darcy-Forchheimer and magnetic field factors. Furthermore, the temperature curve intensifies with the addition of porosity factor and Deborah number, while lessens with the rising influence of power index.

Summary: In 2012, Rivaie et al. proposed the RMIL conjugate gradient (CG) method, which has global convergence under exact line search. However, Dai (2016) discovered convergence abnormalities and introduced restricted RMIL CG parameter as a solution. This paper suggests an efficient RMIL spectral CG method, which does not require additional conditions usually imposed on RMIL. Numerical experiments on benchmark problems and applications in arm robotic model and image restoration demonstrate the promising and efficient performance of the proposed method.

Summary: This article introduces the circular Pythagorean fuzzy set (C-PFS) model, which is a generalization of the circular intuitionistic fuzzy set model. The C-PFS model improves performance by extending intuitionistic fuzzy sets to Pythagorean fuzzy sets. The novel disc Pythagorean fuzzy sets (D-PFSs) are also introduced as a generalization of C-PFSs. The article discusses algebraic and arithmetic operations on D-PFSs and explores the properties of circular Pythagorean fuzzy weighted average/geometric aggregation operators. The COmbinative Distance based ASsesment approach is expanded to the D-PFS framework and applied to a case study.

Summary: In this paper, we investigate the problem of finding a zero of sum of two accretive operators in the setting of uniformly convex and q-uniformly smooth real Banach spaces (q > 1). We incorporate the inertial and relaxation parameters in a Halpern-type forward-backward splitting algorithm to accelerate the convergence of its sequence to a zero of sum of two accretive operators. Furthermore, we prove strong convergence of the sequence generated by our proposed iterative algorithm. Finally, we provide a numerical example in the setting of the classical Banach space l4(R) to study the effect of the relaxation and inertial parameters in our proposed algorithm.
