First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet

Communications on Pure and Applied Mathematics, EarlyView.
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

Jump resonance in the driven Chua's circuit to design frequency selective devices

International Journal of Circuit Theory and Applications, EarlyView.
The paper defines the conditions for the emergence of jump resonance in the driven Chua's circuit. Jump resonance features are characterized by means of numerical simulations and through an experimental circuit. Guidelines to design the Chua's circuit parameters to have the desired jump features are introduced, providing a strategy to realize highly ...

Analysis of image formation in optical palpation

Journal of Biophotonics, EarlyView.
Optical palpation is an emerging elastography technique that generates images of mechanical stress at the tissue surface, with applications in intraoperative cancer detection. Image formation is simulated using finite element analysis and validated with experiments on silicone phantoms, providing an analysis of trends in detectability, feature ...

Angular distribution toward the points of the neighbor‐flips modular curve seen by a fast moving observer

Mathematische Nachrichten, EarlyView.
Abstract Let h$h$ be a fixed non‐zero integer. For every t∈R+$t\in \mathbb {R}_+$ and every prime p$p$, consider the angles between rays from an observer located at the point (−tJp2,0)$(-tJ_p^2,0)$ on the real axis toward the set of all integral solutions (x,y)$(x,y)$ of the equation y−1−x−1≡hmodp$y^{-1}-x^{-1}\equiv h \left(\mathrm{ mod\;}p\right)$ in

Enhancing Efficiency in Multiscale Simulation: Comparing a Lagrange Multiplier Based Approach and a Weak Staggered Coupling With Optional SPML Interface for Wave Propagation

International Journal for Numerical Methods in Engineering, EarlyView.
ABSTRACT The representation of material failure due to wave propagation is essential for the numerical analysis of engineering structures under high dynamic loading. Explicit time integration schemes are well established for this kind of application.

Time‐Multiplexed Reservoir Computing with Quantum‐Dot Lasers: Impact of Charge‐Carrier Scattering Timescale

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Reservoir computing with optical devices offers an energy‐efficient approach for time‐series forecasting. For quantum‐dot lasers with optical self‐feedback, the scattering timescale R into the quantum‐dot levels changes the predictive performance of the reservoir computer.

Rate‐type and integral‐type sectional analysis for time‐dependent response with the fib Model Code 2020

Structural Concrete, EarlyView.
Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

Shear transfer model for ultra‐high‐performance concrete incorporating fiber bridging mechanism

Structural Concrete, EarlyView.
Abstract Ultra‐high‐performance concrete (UHPC) exhibits exceptional mechanical properties, including high shear strength, partly attributed to the fiber bridging mechanism. However, existing shear transfer models for normal‐strength concrete have not considered the significant contribution of fibers.

Degeneration of SL(n)-bundles on a reducible curve [PDF]

arXiv, 2001
We constructed a projective moduli space of semistable torsion free sheaves with `fixed determinant' on a reducible curve. When a family of smooth curves degenerates to the reducible curve, our moduli space is a degeneration of the moduli spaces of semistable vector bundles with a fixed determinant on the smooth curves.

Calculation and experimental verification of equivalent distributed circuit model based on refined iron core modelling

High Voltage, EarlyView.
Abstract This research introduces an equivalent circuit model and a computational method to address complex mechanical motion issues through electromechanical analogies. The study initially refines core vibration characteristics using single‐ and multi‐degree‐of‐freedom models, subsequently establishing equivalent circuit models for these various ...
