    Bell wavelet-based numerical algorithm for fractional-order (1+1)-dimensional telegraph equations involving derivative in Caputo sense
    (2025) Yadav, Pooja
    This study presents an efficient numerical approach for solving fractional-order (1+1)-dimensional telegraph equations using a collocation method based on Bell wavelets. The method begins by exploring the fundamental properties of Bell polynomials and their associated wavelets. Fractional-order operational matrices of integrals (OMI) are developed using block-pulse functions, and the Bell wavelet OMI is then combined with collocation points to transform the telegraph equation into a system of algebraic equations. Newton’s iterative technique is used to solve these equations. To validate the effectiveness and applicability of the proposed Bell wavelet method, several test problems are analyzed, with detailed error analysis included. Comparative results between the Bell wavelet approximate solutions and those from other established methods in the existing literature are presented through comprehensive figures and tables. This comparison highlights the improved accuracy and efficiency of the Bell wavelet method, demonstrating its potential as a reliable tool for solving fractional telegraph equations.

    Red blood cells as an efficient in vitro model for evaluating the efficacy of metallic nanoparticles
    (3 Biotech, 2019) Wadhwa, Ridhima; Aggarwal, Taru; Chandra, Pranjal; Yadav, Pooja; Maurya, Pawan Kumar; Kumari, Vandana; Reddy, Boda Sai Charan
    Blood and the linings of blood vessels may be regarded as a fifth tissue type. The human body contains 5 × 109 red blood cells (RBCs) per ml, a total of 2.5 × 1013 cells in the 5 l of blood present in the body. With an average lifetime of 125 days, human RBCs are destroyed by leukocytes in the spleen and liver. Nowadays red blood cells are extensively used to study various metabolic functions. Nanoparticles (NP) are being widely accepted for drug delivery system. This review summarizes the red blood cells, NPs and their characteristics on the basis of the RBC components along with drug delivery systems through RBCs. Further, we also discussed that how erythrocytes can be used as an efficient in vitro model for evaluating the efficacy of various nanocomposite materials.
