Symmetry Breaking in Chemical Systems: Engineering Complexity Through Self‐Organization and Marangoni Flows

Advanced Science, Volume 13, Issue 5, 27 January 2026.
We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Existence and Uniqueness Result for Fuzzy Fractional Order Goursat Partial Differential Equations

Fractal and Fractional
In this manuscript, we discuss fractional fuzzy Goursat problems with Caputo’s gH-differentiability. The second-order mixed derivative term in Goursat problems and two types of Caputo’s gH-differentiability pose challenges to dealing with Goursat ...

Enterprise Compliance Risk Identification and Economic Management Optimization Based on Dynamic Bayesian Network

Engineering Reports, Volume 8, Issue 1, January 2026.
This study demonstrates the significant value of a collaborative framework integrating DBN and DRL for enterprise compliance risk identification and economic management optimization. The proposed approach not only overcomes the limitations of traditional models in dynamic risk modeling but also achieves synergistic optimization of risk control and ...

A new analytical algorithm for uncertain fractional differential equations in the fuzzy conformable sense

AIMS Mathematics
This paper aims to explore and examine a fractional differential equation in the fuzzy conformable derivative sense. To achieve this goal, a novel analytical algorithm is formulated based on the Laplace-residual power series method to solve the fuzzy ...

A Proposed Analytical Method for Solving Fuzzy Linear Initial Value Problems

مجلة بغداد للعلوم, 2020
In this article, we aim to define a universal set consisting of the subscripts of the fuzzy differential equation (5) except the two elements  and , subsets of that universal set are defined according to certain conditions.

Spherical Deconstruction

, 2005
We present evidence that N=1* SUSY Yang-Mills provides a deconstruction of a six-dimensional gauge theory compactified on a two-sphere. The six-dimensional theory is a twisted compactification of N=(1,1) SUSY Yang-Mills theory of the type considered by ...

A Survey of SIR‐Based Differential Epidemic Models for Control and Security Against Malware Propagation in Computer Networks

SECURITY AND PRIVACY, Volume 9, Issue 1, January/February 2026.
ABSTRACT Unarguably, malware and their variants have metamorphosed into objects of attack and cyber warfare. These issues have directed research focus to modeling infrastructural settings and infection scenarios, analyzing propagation mechanisms, and conducting studies that highlight optimized remedial measures.

Introducing Learnable Gaussian Noise Into Defed for Enhanced Defense Against Adversarial Attacks in Fingerprint Liveness Detection

IET Biometrics, Volume 2026, Issue 1, 2026.
Deep learning has significantly improved the performance of fingerprint liveness detection, while susceptibility to adversarial attacks remains a critical security challenge. Existing input transformation–based defense methods, including JPEG compression, total variance minimization (TVM), high‐level representation guided denoiser (HGD), and Defed, are

Design of Novel Exponential PDN Controller via Quadratic Interpolation Optimiser for Nonlinear and Unstable Ball and Beam System

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel exponential proportional‐derivative controller with filter (exp‐PDN) for stabilising the nonlinear and underactuated ball and beam system. Unlike conventional PID‐based approaches, the proposed controller removes the integral term, resulting in faster transient responses and improved robustness.
