The process of microwave heating involves the coupling of multiple physical phenomena, specifically including the distribution of the electromagnetic field in the resonant cavity. The electromagnetic effect generates heat and encourages the transfer of heat inside the material. In this numerical study, a 3D computer model of microwave heating of Al2O3/SiC composites using a multimode microwave heating chamber was established based on the simulation software COMSOL Multiphysics 5.6, and the symmetry treatment of the model was carried out, which effectively reduced the amount of model calculations and accurately analyzed the microwave heating characteristics of the samples. The analysis of the microwave heating characteristics of the sample was mainly preformed from the perspective of the electric field distribution in the resonant cavity, the sample heating rate and the sample heating uniformity, and then it was determined how the microwave source power and sample mold selection affect the temperature and electric field parameters of the sample. After experimental verification, the error between the simulation results and the temperature parameters obtained from the actual experiments is less than 2%. This study contributes to further understanding the heating behavior of Al2O3/SiC composites in complex multimode microwave heating environments and can be used to control the dynamic parameters during microwave heating in order to improve the heating rate and heating uniformity of samples.

Title: Symmetry in Smart Computing and Intelligent Systems
Editor: Prof. Dr. Julio Alejandro Romero Gonzalez, Prof. Dr. Diana-Margarita Córdova-Esparza and Prof. Dr. Juan R. Terven
Details: https://brnw.ch/21x3765

In recent years, the study of complex systems has evolved toward an approach that integrates computational modeling and numerical simulation, where symmetry and asymmetry play fundamental roles in both physical models and computational systems. Traditionally, this field has relied on mathematical modeling, simulations, and the development of numerical methods to understand structural changes and behaviors in systems with multiple interactions. Currently, the integration of artificial intelligence and the analysis of large-scale data enable the identification of patterns, the acceleration of simulations, and the development of more robust predictive models. In this Special Issue, original research articles and reviews are welcome.

Partial Imaginary Transition State (ITS) Graphs: A Formal Framework for Research and Analysis of Atom-to-Atom Maps of Unbalanced Chemical Reactions and Their Completions

Atom-to-atom maps (AAMs) are bijections that establish the correspondence of reactant and product atoms across chemical reactions. They capture crucial features of the reaction mechanism and thus play a central role in modeling chemistry at the level of graph transformations. AAMs are equivalent to so-called “imaginary transition state” (ITS) graphs, making it possible to reduce tasks such as the computational comparison of AAMs to testing graph isomorphisms. In many application scenarios, nonetheless, only partial information is available, i.e., only partial maps or, equivalently, only subgraphs of the ITS graphs, are known. Here, we investigate whether and how, and to what extent, such partial chemical data can be completed and compared. The focus of this contribution is entirely on the development of a solid mathematical foundation for the analysis of partial AAMs and their associated partial ITS graphs.

Title: Structural Mechanics of Regularity and Irregularity in Masonry Constructions
Editor: Dr. Abide Aşıkoğlu, Dr. Francesco Parisse and Dr. Nicoletta Bianchini
Details: https://brnw.ch/21x33eu

We are pleased to invite you to submit a contribution to a Special Issue entitled “Structural Mechanics of Regularity and Irregularity in Masonry Constructions” that will be published in Symmetry. In seismic design, structural regularity is widely regarded as a prerequisite for reliable performance. Accordingly, seismic design codes encourage adopting simple and box-like configurations for masonry buildings to promote structural regularity. However, perfect regularity is rarely attainable in practice due to functional requirements, economic constraints, and architectural preferences. Even in nominally regular or symmetric buildings, masonry anisotropy, discontinuities, and morphology of load-bearing walls, as well as the size, number and distribution of openings introduce directional stiffness and strength variations that are progressively reconfigured with damage accumulation. As a result, irregularity in masonry is inherent, and its mechanics and response must be understood rather than avoided. Within this framework, this Special Issue aims to advance the understanding of irregularity in masonry constructions as a concept, foster research on their implications on structural behaviour, and to provide a platform for discussing the analytical, numerical, and experimental challenges associated with evaluating the response of such systems.

Transfer Learning-Based Steering Angle Prediction and Control with Fuzzy Signatures-Enhanced Fuzzy Systems for Autonomous Vehicles

This paper presents an End-to-End steering angle prediction and control framework for autonomous vehicles that combines transfer learning-based computer vision with fuzzy signatures‑enhanced fuzzy control in electric power steering systems. The proposed VGG16-based model achieves a 22.63% lower Mean Squared Error than the original NVIDIA End-to-End model while using fewer trainable parameters, and the fuzzy signatures-based controller robustly drives the steering motor to the desired angle in simulation. By efficiently handling uncertain driving conditions and reducing data and computational demands, the approach demonstrates strong potential for more accurate and resource‑efficient autonomous steering systems.

What makes low-dimensional quantum systems so fascinating?

In one dimension, interactions and disorder can completely reshape the behavior of matter, giving rise to exotic quantum phases and collective phenomena that do not exist in ordinary systems.

For decades, Thierry Giamarchi has been one of the leading figures defining this field. His work on Tomonaga–Luttinger liquids and the Bose glass phase fundamentally changed how physicists understand interacting quantum materials, quantum spin chains, and ultracold atomic systems.

At , Prof. Giamarchi will join leading researchers exploring the future of modern mathematical physics, quantum matter, and many-body systems.

If your research touches on condensed matter physics, AMO physics, integrability, or quantum many-body theory, we warmly invite you to submit your work and join the discussion.
