AIMS Mathematics, 2022 In this paper, we study a kind of dual generalized inverses of dual matrices, which is called the dual group inverse. Some necessary and sufficient conditions for a dual matrix to have the dual group inverse are given.

Inverse Synthetic Aperture Radar Sparse Imaging Exploiting the Group Dictionary Learning
Remote Sensing, 2021 Sparse imaging relies on sparse representations of the target scenes to be imaged. Predefined dictionaries have long been used to transform radar target scenes into sparse domains, but the performance is limited by the artificially designed or existing ...

Postulates for the inverse operations in a group [PDF]
Transactions of the American Mathematical Society, 1930 It may happen that the function F is of such a character that when the 5-symbols z, x are given in (1), an c5-symbol y is uniquely determined, and when the25-symbols y, z are given in (1), an25-symbol x is uniquely determined. In this case we may associate with the function F(x, y) two other one-valued functions y = G (z, x), x = H (y, z) defined over ...

Resistance Distance in H-Join of Graphs G1,G2,…,Gk
Mathematics, 2018 In view of the wide application of resistance distance, the computation of resistance distance in various graphs becomes one of the main topics. In this paper, we aim to compute resistance distance in H-join of graphs G 1 , G 2 , … , G k

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

On the Explicit Formula for Eigenvalues, Determinant, and Inverse of Circulant Matrices
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 Determining eigenvalues, determinants, and inverse for a general matrix is computationally hard work, especially when the size of the matrix is large enough.

Molecular Oncology, EarlyView.This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.
