Abstract

In this investigation, a new algorithm based on the compact difference method is proposed. The purpose of this investigation is to solve the 2D time-fractional integro-differential equation. The Riemann–Liouville derivative was utilized to define the time-fractional derivative. Meanwhile, the weighted and shifted Grünwald difference operator and product trapezoidal formula were utilized to construct a high-order numerical scheme. Also, we analyzed the stability and convergence. The convergence order was O (τ 2 + h x 4 + h y 4) , where τ is the time step size, h x and h y are the spatial step sizes. Furthermore, several examples were provided to verify the correctness of our theoretical reasoning. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we propose a novel approach for solving two-dimensional time-fractional advection–diffusion equations, where the fractional derivative is described in the Caputo sense. The discrete scheme is constructed based on the barycentric rational interpolation collocation method and the Gauss–Legendre quadrature rule. We employ the barycentric rational interpolation collocation method to approximate the unknown function involved in the equation. Through theoretical analysis, we establish the convergence rate of the discrete scheme and show its remarkable accuracy. In addition, we give some numerical examples, to illustrate the proposed method. All the numerical results show the flexible application ability and reliability of the present method.

25. Technological Diversity in M&A Network and High-Quality Development of Enterprises.

Abstract

This study breaks through the homogeneity of mergers and acquisitions (M&A) and the dyadic relationship between the acquirer and the target firm. We consider the network content of technological diversity that reflects both acquirers–target firms and target firms–target firms. The study empirically explores the impact and mechanism of technological diversity in M&A network on the high-quality development of enterprises (HQDE). Our study reveals that technological diversity in M&A network has an inverted U-shaped effect on HQDE. Mechanism analysis shows that the technological diversity in M&A network affects HQDE through both the quantity and quality of technological innovation. The findings provide novel insights to enable acquirers to select appropriate target firms and overcome technological innovation dilemmas, thus advancing toward high-quality development.

Abstract

Introduction: Oxidative stress and inflammatory responses are often the predominant detrimental factors associated with spinal cord injury (SCI). This study investigates the potential therapeutic effects of albiflorin (AF) on alleviating inflammation and oxidative stress in the rat model with SCI. Methods: Initially, the behavior of SCI‐induced rats is examined by Basso−Beattie−Bresnahan score and the inclined plane examination. Then, the immunohistochemical staining of inflammasome‐related protein (for instance, NACHT, LRR, and PYD domains‐containing protein 3, NLRP3) is performed in combination with enzyme‐linked immunosorbent assay (ELISA) of corresponding proinflammatory factors to assess the immunomodulatory effects of AF. Further, the markers involved in oxidative stress are examined by ELISA and western blot analysis analyses. Results: These findings indicated that AF could alleviate motor dysfunction and the loss of neuron cells in SCI‐induced rats. Mechanistically, AF could attenuate the inflammatory responses by reducing oxidative stress and activating nuclear erythroid‐related factor 2 (Nrf2)/heme oxygenase‐1 (HO‐1) pathway in SCI rats. Depleting the antioxidant capacity by inhibiting glutathione biosynthesis could counteract the anti‐inflammatory activity of AF in SCI rats. Conclusions: Together, our data suggested that AF could serve as a potential therapeutic agent against the aggravation of SCI in rats. [ABSTRACT FROM AUTHOR]
