Hamiltonian and Q-Inspired Neural Network-Based Machine Learning
IEEE Access, 2020 The goal of this study is to present a universal large-scale machine learning model based on spectral processing. By machine learning, we mean input-output mapping approximation generated by training sets.

Mathematical Modelling and Analysis, 2023 In the paper, we construct an absolutely convergent Dirichlet series which in the mean is close to the periodic Hurwitz zeta-function, and has the universality property on the approximation of a wide class of analytic functions.

The approximation property for spaces of Lipschitz functions [PDF]
, 2014 Let $\mathrm{Lip}_0(X)$ be the space of all Lipschitz scalar-valued functions on a pointed metric space $X$. We characterize the approximation property for $\mathrm{Lip}_0(X)$ with the bounded weak* topology using as tools the tensor product, the ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

The ασ-Approximation Property and Its Related Operator Ideals
MathematicsIn this paper, we study the σ-tensor norm (ασ), the absolutely τ-summing operator and the σ-nuclear operator. We characterize the ασ-approximation property in terms of some density of the space of absolutely τ-summing operators.

Can local particle filters beat the curse of dimensionality?
, 2015 The discovery of particle filtering methods has enabled the use of nonlinear filtering in a wide array of applications. Unfortunately, the approximation error of particle filters typically grows exponentially in the dimension of the underlying model ...

On Topological Properties of IF Approximation Spaces [PDF]
Fuzzy Information and Engineering, 2015 AbstractRough approximation operators in approximation spaces are the core concept of rough set theory, which draw close links between rough set theory and topology. In this paper, we investigate rough approximation operators, study IF topologies induced by reflexive IF relations and give topological properties of IF approximation spaces.

On approximation property of multipoint flux approximation method [PDF]
, 2007 Approximation property of multipoint flux approximation (MPFA) approach for elliptic equations with discontinuous full tensor coefficients is discussed here. Finite volume discretization of the above problem is presented in the case of jump discontinuities for the permeability tensor. First order approximation for the fluxes is proved.

Molecular Oncology, EarlyView.There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...
