On cost and revenue in circular supply chains: Where to close the loop? by Herbert Jodlbauer, Matthias Thürer, Ann-Kristin Thienemann

“…However, most research focuses on dyadic or triadic supply chain structures. Where to close the loop, i.e., where to position the recycler, repurposer, remanufacturer, refurbisher, repairer, and/or reuser, in multi-tier supply chains remains largely unanswered. …”

Potential of Nonlinear Ultrasonic Indicators for Nondestructive Testing of Concrete by C. Payan, V. Garnier, J. Moysan

“…In a second part, we demonstrate the high sensitivity of nonlinear parameters to thermal damage as regard with linear ones. Then, the influence of water content and porosity on these indicators is quantified allowing to uncouple the effect of damage from environmental or structural parameters.…”

Propagation of electromagnetic waves in anisotropic magnetoelectric medium by S.K. Tleukenov, M.K. Zhukenov, N.A. Ispulov

“… In the article we consider porpagation and interaction of electromagnetic waves of different polarization, in anisotropic medium that is inhomogeneous along the Z axis with magnetoelectric effect of tetragonal, trigonal, and hexagonal symmetries are described by the structure of the matrix coefficients. The matricant structure of the original system of equations follows from the structure of coefficient matrix. …”

Performance assessment and strengthening proposal of an existing building by R. Tuğrul Erdem, Koçali Karal

“…Consequently, the evaluation of seismic performance and strengthening techniques of the existing buildings according to various seismic codes has become a global issue in structural engineering. With the development of computer technology, non-linear methods have been offering increasingly reliable evaluation procedures in the performance-based assessment of buildings. …”

Factors influencing internet addiction among university students: The mediating roles of self-control and anxiety by Man Chen, Xinyu Zhang

“…This study aims to explore the key factors affecting internet addiction among college students, analyzing how stress, social support, self-efficacy, self-control, and anxiety influence internet addiction and their interrelationships and mechanisms. A structured survey was administered to 538 students from Zhengzhou Vocational University of Information and Technology, Henan University of Chinese Medicine, Henan Polytechnic, employing a two-stage Structural Equation Modeling-Artificial Neural Network (SEM-ANN) to uncover non-compensatory and non-linear relationships. …”

Nonlinear Vibration of Multi-Walled Carbon Nanotubes with Initial Curvature Resting on Elastic Foundations in a Nonlinear Thermo-Magnetic Environment by Gbeminiyi Musibau SOBAMOWO, James A. AKANMU, Olurotimi A. ADELEYE, Samuel AKINGBADE, Ahmed Amao YINUSA

“…Therefore, this can be used for the restraining of the chaos vibration in the objective structure. These research findings will assist the designers and manufacturers in developing multi-walled carbon nanotubes for various structural, electrical, mechanical, and biological applications, especially in the areas of designing nanoelectronics, nanodevices, nanomechanical systems, nanobiological devices, and nanocomposites, and particularly when they are subjected to thermal loads, magnetic fields and elastic foundations.…”

On new rational non-dynamical ABCD matrices for quadratic classical and quantum algebras by T. Skrypnyk

“…We consider classical and quantum non-dynamical quadratic abcd Lax algebras with rational classical and quantum gl(n)⊗gl(n)-valued abcd-tensors satisfying a set of quadratic “differential” or “semi-dynamical” [3] Yang-Baxter-type equations generalizing those of Fredel and Maillet [2]. The linearization of the corresponding quadratic structure lead to linear tensor structure with the classical gl(n)⊗gl(n)-valued non-dynamical, non-skew-symmetric rational r-matrix coinciding with a quasi-graded deformation of the standard skew-symmetric rational r-matrix [7]. …”

Nonlinearity-induced corner states in a kagome lattice by K Prabith, Georgios Theocharis, Rajesh Chaunsali

“…Stability analysis and nonlinear continuation reveal they are intrinsic nonlinear solutions, fundamentally distinct from perturbations of linear topological or bulk states. These findings elucidate a robust mechanism for generating localized states via nonlinearity, independent of linear topological protection, and advance our understanding of how nonlinearity can give rise to novel boundary phenomena in structured media. …”

Hybrid SARIMA+BO-LSTM Framework for Forecasting EV Adoption: A Road to Net-Zero in Ireland by Afaq Khattak, Brian Caulfield

“…To support the Climate Action Plan target of registering 945,000 electric vehicles (EVs) by 2030, this study develops a hybrid time series forecasting framework that combines a Seasonal Autoregressive Integrated Moving Average (SARIMA) model with a Bayesian Optimized Long Short-Term Memory (BO-LSTM) network. SARIMA captures linear and seasonal patterns in monthly EV registration data, while BO-LSTM models the non-linear residual structure. …”

Tree volume modeling of different poplar clones in plantations in the Vojvodina region by Pantić Damjan, Borota Dragan, Janjatović Živan

“…Due to this sampling structure, it was not possible to build models (tables) at the level of clone, alluvium, soil type and plant spacing, but they were built based on the combined data for the whole area (Vojvodina), with certain exceptions - for I-214 (clone spacing and plant form) by applying the Schumacher-Hall linear mixed hierarchical (cluster) model; for M1 (clone) by applying classical regression analysis and for Deltoid clones (clona-alluvium of the Sava, alluvium of the Danube) by ap­plying the mixed linear hierarchical model, as in the case of I-214. …”
