The article presents an overview report of the 12th International Conference on Compressors and their systems which was held in a hybrid format from September 6 to 8, 2022 in the City, University of London, UK. At this prestigious scientific and ed

The representations that can be defined starting from positive sesquilinear maps {\Phi} with values in an ordered Banach module are essentially of two types: if {\Phi} is positive, a natural generalization follows the path of the GNS construction; if

We present a purely deep neural network-based approach for estimating long memory parameters of time series models that incorporate the phenomenon of long-range dependence. Parameters, such as the Hurst exponent, are critical in characterizing the lo

The C++ programming language and its cousins lean towards a memory-inefficient storage of structs: The compiler inserts helper bits into the struct such that individual attributes align with bytes, and it adds additional bytes aligning attributes wit

In this paper, we characterize supercyclic weighted composition operators on various function spaces. Moreover, we also characterize supercyclic adjoint of the weighted composition operator and supercyclic left multipliers acting on the space of comp

In this paper, we provide a representation of a certain class of C*-valued positive sesquilinear and linear maps on non-unital quasi *-algebras. Also, we illustrate our results on the concrete examples of non-unital Banach quasi *-algebras, such as t

The GNS construction for positive invariant sesquilinear forms on quasi *-algebras is generalized to a class of positive C*-valued sesquilinear maps on quasi *-algebras. The result is a *-representation taking values in a space of operators acting on

In this paper, we extend Fredholm theory in von Neumann algebras established by Breuer in [5] and [6] to spectral Fredholm theory. We consider 2 by 2 upper triangular operator matrices with coefficients in a von Neumann algebra and give the relations
