Integrable operators and squares of Hankel operators. [PDF]

open access: yes, 2007
Integrable operators arise in random matrix teory, where they describe the asymptotic distributions of large self-adjoint random matrices from the generalized unitary ensembles.

On generalized Bessel–Maitland function

open access: yesAdvances in Difference Equations, 2021
An approach to the generalized Bessel–Maitland function is proposed in the present paper. It is denoted by J ν , λ μ $\mathcal{J}_{\nu , \lambda }^{\mu }$ , where μ > 0 $\mu >0$ and λ , ν ∈ C $\lambda ,\nu \in \mathbb{C\ }$ get increasing interest from ...

On a product of modified Bessel functions [PDF]

open access: yesProceedings of the American Mathematical Society, 2008
Summary: Let \(I_{\nu}\) and \( K_{\nu}\) denote the modified Bessel functions of the first and second kinds of order \( \nu.\) In this note we prove that the monotonicity of \( u \mapsto I_{\nu}(u)K_{\nu}(u)\) on \( (0,\infty)\) for all \( \nu\geq -1/2\) is an almost immediate consequence of the corresponding Turán type inequalities for the modified ...

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

open access: yesAdvanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Accelerating Sustainable Epoxy Resin Development Through Bayesian Optimization and Inverse Design

open access: yesJournal of Applied Polymer Science, EarlyView.
Development of a machine learning framework for the optimization of the Tg of partially bio‐based epoxy resin formulations in a 13‐component design space using Bayesian optimization, active learning, random design, and inverse design. The results show that the BO effectively navigates high‐dimensional formulation spaces, and the final ML model could ...
