Boundary confining dualities and Askey-Wilson type q-beta integrals

Journal of High Energy Physics, 2023
We propose confining dualities of N $$ \mathcal{N} $$ = (0, 2) half-BPS boundary conditions in 3d N $$ \mathcal{N} $$ = 2 supersymmetric SU(N), USp(2n) and SO(N) gauge theories.

Seamless integration of global Dirichlet-to-Neumann boundary condition and spectral elements for transformation electromagnetics [PDF]

, 2015
In this paper, we present an efficient spectral-element method (SEM) for solving general two-dimensional Helmholtz equations in anisotropic media, with particular applications in accurate simulation of polygonal invisibility cloaks, concentrators and ...

Smarter Sensors Through Machine Learning: Historical Insights and Emerging Trends across Sensor Technologies

Advanced Functional Materials, EarlyView.
This review highlights how machine learning (ML) algorithms are employed to enhance sensor performance, focusing on gas and physical sensors such as haptic and strain devices. By addressing current bottlenecks and enabling simultaneous improvement of multiple metrics, these approaches pave the way toward next‐generation, real‐world sensor applications.

Alkali Ion‐Incorporated HfO2 Dielectrics for Reconfigurable Neuromorphic Computing

Advanced Functional Materials, EarlyView.
This work presents an indium gallium zinc oxide (IGZO) transistor with an alkali cation‐integrated hafnium dioxide (HfO2) dielectric exhibiting synaptic behavior via ion retention. The solution‐based film fabrication strategy overcomes the limitations of atomic layer deposition (ALD) and precursor coating, enabling the control of synaptic retention ...

No hair theorem for bound-state massless static scalar fields outside horizonless Neumann compact stars

Physics Letters B, 2019
We study no-hair theorem for horizonless objects, being subject to Neumann boundary conditions. For massive scalar fields, a no hair theorem for Neumann compact stars was proved by us in a previous paper, where the nonzero scalar field mass condition is ...

Higher order Nevanlinna functions and the inverse three spectra problem [PDF]

Opuscula Mathematica, 2016
The three spectra problem of recovering the Sturm-Liouville equation by the spectrum of the Dirichlet-Dirichlet boundary value problem on \([0,a]\), the Dirichlet-Dirichlet problem on \([0,a/2]\) and the Neumann-Dirichlet problem on \([a/2,a]\) is ...

On inverse problem for tree of Stieltjes strings

Pracì Mìžnarodnogo Geometričnogo Centru, 2021
For a given metric tree and two strictly interlacing sequences of numbers there exits a distribution of point masses on the edges (which are Stieltjes strings) such that one of the sequences is the spectrum of the   spectral problem  with the Neumann ...

Structure–Transport–Ion Retention Coupling for Enhanced Nonvolatile Artificial Synapses

Advanced Functional Materials, EarlyView.
Nitrogen incorporation into the conjugated backbone of donor–acceptor polymers enables efficient charge transfer and deep ion embedding in organic electrochemical synaptic transistors (OESTs). This molecular‐level design enhances non‐volatile synaptic properties, providing a new strategy for developing high‐performance and reliable neuromorphic devices.

General approach to the line source electromagnetic scattering by a circular strip: Both E‐ and H‐polarisation cases

IET Microwaves, Antennas & Propagation, 2021
This study presents a new approach to line‐source diffraction by a circular strip. The investigation is obtained by employing both electric and magnetic line sources where the corresponding field components satisfy the Dirichlet and Neumann boundary ...
