A novel viscous-damping rubber bearing for dual control of operational vibration and seismic response of electrical equipment

Electrical equipment is vulnerable to seismic excitation and operational vibration, which compromises its safety and operational stability. This study proposes a novel viscous-damping rubber bearing (VDRB) that integrates laminated thick-rubber layers with a viscous damping compo...

Deep learning approaches for high-frequency carbon futures price forecasting: A comparative analysis of recurrent, attention-based, convolutional, and hybrid models

Carbon markets have expanded rapidly in recent years as part of climate change mitigation efforts. Accurate forecasting of the European Union Emissions Trading System (EU-ETS) futures prices holds significant value for companies, investors, and policymakers, who rely on these for...

A Graph-based Approach to Predicting Protein-Protein Interactions

Accurate identification of protein-protein interactions (PPIs) is fundamental for understanding cellular mechanisms and facilitating drug discovery. Although high-throughput experimental methods have expanded the known interactome, they remain resourceintensive and prone to noise...

Testing Robustness of Temporal Transportation Networks via Interval Separators

This paper addresses the problem of identifying time interval separators in temporal networks. We introduce d-MinIntSep, a new variant of the temporal separator problem, which models failures as time intervals assigned to vertices and aims to block all temporal paths between a so...

The bosonic Hubbard model on a three dimensional flat band lattice

The lowest eigenstates of the hopping matrix on the line graph of a cubic lattice with periodic boundary conditions are highly degenerate, they form a lowest flat band. Further, these states are localized. If one considers a repulsive bosonic Hubbard model on this lattice it is p...

‘Africa Rising’ revisited: African states and the politics of emergence

The notion of Africa’s emergence has become a dominant framework through which governments, international organisations and development actors imagine the continent’s future. While existing scholarship has largely assessed whether African economies are genuinely ‘emerging’ by rel...

An interpolating element free Galerkin scaled boundary method for elastostatic sensitivity analysis

To enable efficient and accurate first-order derivative computations of structural responses with respect to design parameters, this paper proposes a semi-analytical approach termed the interpolating element-free Galerkin scaled boundary method (IEFG-SBM) for elastostatic sensiti...

Constitutive Modeling and Stress Evolution Analysis for Advanced TRISO-Type Nuclear Fuel

Driven by the development of High-Temperature Gas-cooled Reactors (HTGRs) and advanced microreactors, TRISO particles have emerged as a critical structural component, whose mechanical reliability directly affects the safety limits of these advanced energy systems. This study deve...

CGAN-Based Surrogate Model for Predicting Von Mises Stress Distribution in 3D Structures

U-Net branches. Encoder features from the first two-time branches are forwarded and reused in the decoder of the third branch, promoting cross-layer feature sharing and more coherent stress patterns along the time-like axis. Numerical experiments show that the proposed surrogate...

Malaysia Factor Model: A Case for Uncoupling Fama-French Emerging Markets' Factors

The development of Islamic equity markets is a growing phenomenon that warrants the development of an asset pricing model that is able to accurately model returns. In this paper, we investigate whether the five-factor (5-factor) model is more suitable to compute expected returns...

Noether Symmetries of SU(2) Yang–Mills Dark Energy in Nonmetricity Gravity

We investigate an isotropic SU(2) Yang–Mills cosmic triad in symmetric teleparallel, or nonmetricity, gravity. The model contains a non-minimal coupling [Formula: see text], a field-dependent Yang–Mills kinetic coupling [Formula: see text], and a self-interaction potential [Formu...

Spin-(0, 1, 1 2) Field Perturbations, Quasinormal Modes, Overtones, Greybody Factors and Strong Cosmic Censorship of Einstein-Skyrme Black Holes

We study scalar, electromagnetic (EM) and Dirac perturbations of the four-dimensional Einstein-Skyrme (ES) black hole (BH), an asymptotically flat solution carrying a global-monopole solid-angle deficit, whose lapse [Formula: see text] is controlled by two independent inputs of t...

Geometry-dependent chaos: A unified framework for anisotropic dynamical systems via Trinition deformation

This work develops a Trinition-based framework for geometry-dependent chaotic dynamics. The Trinition construction is represented on a three-component primitive space, while its multiplication law generates both an anisotropic quadratic geometry and an additional interaction-acce...

Precision-Aware Variable Bit Processing Elements for Hardware-Efficient Systolic Array Designs

Systolic arrays (SAs) have emerged as prominent hardware accelerators for matrix operations in deep learning, while floating point number formats enable precision control across computational domains. Approximate computing involves trading precision for improved performance in ap...

Physical Selection of Cartan Soft Breakings in a Broken SU (3) Yang–Mills Model

We revisit the broken-[Formula: see text] Yang–Mills model with a soft quadratic color deformation induced by the dimension-two operator [Formula: see text], previously studied for a constant source aligned along the color-3 direction. We extend the construction to a generic Cart...

Using Self-Affine Fractal Functions and Dimensions to Characterize the Dynamic Phase Transition of Sardine Schools

This paper uses self-affine fractal functions to characterize the phase transition in dy- namic images of sardine schools and identifies critical points of phase transition through the rate of change in box dimension, generalizing the application of fractal theory in the study of...

Spectrum occupies pseudospectrum for random matrices with diagonal deformation and variance profile

We consider n × n non-Hermitian random matrices with independent entries and a variance profile, as well as an additive deterministic diagonal deformation. We show that their empirical eigenvalue distribution converges to a limiting density as n tends to infinity and that the sup...

In this paper, we study anisotropic compact stellar configurations in the framework of modified [Formula: see text] gravity using the Karmarkar embedding condition using Durgapal metric potential. Exact interior solutions for the power-law model [Formula: see text] are obtained a...

Pricing of perpetual American options in diffusion models with progressively enlarged filtrations

We study the problems of pricing of perpetual American options in one-dimensional positive diffusion models of financial markets with progressively enlarged Brownian reference filtrations. It is assumed that the reward processes represent integrals of discounted continuous piecew...

Investigation on properties of continuous functions under variable-order fractional integral and its application in joint fire allocation modeling

As a natural extension of constant-order fractional operators, variable-order fractional calculus can characterize the spatiotemporal heterogeneity of systems in a more refined manner, yet its fundamental mathematical theory remains to be fully established. This paper is devoted...
