STABILITY,ERROR ESTIMATE AND APPROXIMATION OF SOLUTIONS OF NON-LINEAR SYSTEM INTEGRAL EQUATIONS IN DIRECT SUM OF HILBERT SPACE

MINAR International Journal of Applied Sciences and Technology, 2023
In this research, we study stability of solutions with respect to the driver of a system of nonlinear Volterrs integral equations in reproducing Kernel Hilbert space. We study error estimate of solutions in terms of uniform grid numbers of subintervals of [a, b].

Norm Conditions on Resolvents of Similarities of Hilbert Space Operators and Applications to Direct Sums and Integrals of Operators [PDF]

Proceedings of the American Mathematical Society, 1978
Similarities of an operator T are determined so that on certain sets the norm of the resolvents of the similarity satisfy bounding conditions independent of T .

Metamodel construction for sensitivity analysis

ESAIM: Proceedings and Surveys, 2017
We propose to estimate a metamodel and the sensitivity indices of a complex model m in the Gaussian regression framework. Our approach combines methods for sensitivity analysis of complex models and statistical tools for sparse non-parametric estimation ...

Direct sum of lower semi-frames in Hilbert spaces

Gulf Journal of Mathematics
In this paper, structural properties of lower semi-frames in separable Hilbert spaces are explored with a focus on transformations under linear operators (may be unbounded). Also, the direct sum of lower semi-frames, providing necessary and sufficient conditions for the preservation of lower semi-frame structure, is examined.

Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

Advanced Science, EarlyView.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Exploring Quantum Support Vector Regression for Predicting Hydrogen Storage Capacity of Nanoporous Materials

Advanced Intelligent Discovery, EarlyView.
In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...
