Properties of some matrix classes based on principal pivot transform
, 2016 In this article, we study the properties of some matrix classes using principal pivot transform (PPT). These matrices with some additional conditions have nonnegative principal minors.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Streaming Classification with Emerging New Class by Class Matrix Sketching
Proceedings of the AAAI Conference on Artificial Intelligence, 2017 Streaming classification with emerging new class is an important problem of great research challenge and practical value. In many real applications, the task often needs to handle large matrices issues such as textual data in the bag-of-words model and large-scale image analysis.

Direct Exponent and Scalar Multiplication Classes of an MDS Matrix [PDF]
, 2011 An MDS matrix is an important building block adopted by different algorithms that provides diffusion and therefore, has been an area of active research. In this paper, we present an idea of direct exponent and direct square of a matrix.

On Spectrum of Some Classes of Matrix Operators
Izvestiya of Saratov University. New Series. Series: Mathematics. Mechanics. Informatics, 2012 Summary: The paper is devoted to investigation of the spectrum of some classes of matrix operators. The relations between the parts of the spectrum of the matrix operators with corresponding parts of its elements are established.

Generalized notions of amenability for a class of matrix algebras [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2019 We investigate the notions of amenability and its related homological notions for a class of $I\times I$-upper triangular matrix algebra, say $UP(I,A)$, where $A$ is a Banach algebra equipped with a non-zero character. We show that $UP(I,A)$ is pseudo-contractible (amenable) if and only if $I$ is singleton and $A$ is pseudo-contractible (amenable ...
