Summary: Large-scale hydraulic fracturing is crucial for efficient shale oil production, but the mechanisms of fracturing fluid flow in shale micropores and the impact of shale microstructure and physical properties are not well understood. This lack of understanding hinders the optimization of fracturing flowback and limits shale oil recovery enhancement. This study analyzes the characteristics of shale pores using SEM and XRD experiments, finding multiple pore types including organic pores, brittle mineral pores, and clay pores. The study investigates the influence of cross-section shapes on capillary force and analyzes the dynamics of imbibition in different pore types. A shale semi-analytical solution that considers imbibition time, fluid properties, pore cross-section shapes, tortuosity, and forced pressure is established using a shale multi-pores physical model and fractal theory.

Summary: In this study, a new family of inverse iterative numerical techniques is developed to extract all roots of a nonlinear equation simultaneously. Convergence analysis shows that the proposed methods have local 10th-order convergence. Compared to other methods, the inverse simultaneous iterative techniques provide initial estimations to exact roots within a given tolerance while using fewer function evaluations in each iterative step.

Summary: This paper proposes a procedure to transform any iterative scheme into a method for approximating all roots of nonlinear equations simultaneously. The proposed scheme achieves a convergence order twice that of the original method. Numerical tests validate the theoretical results and compare the proposed schemes with other existing methods for simultaneous roots of polynomial and non-polynomial functions.

Summary: This paper visually investigates the dynamics and stability of replacing classical derivatives with fractional derivatives in the standard Newton root-finding method, using alternative iterations to the standard Picard iteration. By applying this process to polynomials on a complex plane, images known as polynomiographs are produced to show basins of attractions for polynomial zeros or the number of iterations required to achieve any polynomial root. The color coding of the images according to the number of iterations reveals the convergence speed and dynamic properties of the processes visualized by the polynomiographs. Additionally, the stability of the methods is investigated using basins of attraction, and a comparison of the modified root-finding methods is demonstrated on the polynomial z(3)-1 in a complex plane.

Summary: This paper investigates the existence of chaos in a type of partial difference equations, and establishes four chaotification schemes using tangent and cotangent functions. The systems are shown to exhibit chaos in the sense of Li-Yorke or both Li-Yorke and Devaney. Three examples are provided for illustration.

Summary: Two new iterative methods have been established for the simultaneous determination of all multiple as well as distinct roots of nonlienar polynomial equations, with very high computational efficiency achieved using two suitable corrections. The convergence analysis shows that the orders of convergence of the newly constructed simultaneous methods are 10 and 12. Numerical test examples are provided to check the efficiency and numerical performance of these simultaneous methods.

Summary: This paper introduces a method to accelerate the convergence speed of the fractional Newton-Raphson method, as well as how Aitken's method can speed up the convergence of iterative methods. Experimental results show that implementing Aitken's method in the F N-R method can lead to faster convergence compared to the simple F N-R method.
