This paper is dedicated to investigating the exponential cluster synchronization in a class of nonlinearly coupled complex networks with non-identical nodes and an asymmetrical coupling matrix. A novel aperiodically intermittent pinning control (APIPC) protocol is presented, which takes full account of the cluster-tree topology structure of the networks and pins only the nodes in the current cluster that have directional links to neighboring clusters. Since it is difficult to precisely determine the intermittent control instants and rest instants of APIPC in advance, the event-triggered mechanism (ETM) is thus proposed. Based on the concept of the minimal control ratio and the segmentation analysis method, sufficient requirements for realizing the exponential cluster synchronization are derived. Moreover, the Zeno behavior of ETM is excluded by rigorous analysis. Eventually, the effectiveness and advantages of the established theorems and control strategies are demonstrated by two numerical simulations.

Recently, the regulatory effect of natural antioxidants on oleogels has attracted the attention of scholars. Whether natural antioxidants with different structures can co-gel with gelators remains unclear. In this study, the impact of water-soluble (dihydroquercetin and epicatechin) and fat-soluble (lycopene and L-ascorbate palmitate) antioxidants on the physicochemical properties of diacylglycerol oleogels was investigated.

Background: Cardiac issues following radiotherapy are increasingly prevalent among patients with thoracic cancer and coronary disease. However, the mechanisms underlying radiotherapy-induced plaque instability and changes in plaque characteristics on imaging remain unclear. This study used single-cell RNA sequencing to identify key features of vulnerable plaques following radiotherapy.

Almost equitable partitions (AEPs) have been linked to cluster synchronization in oscillatory systems, highlighting the importance of structure in collective network dynamics. We provide a general spectral framework that formalizes this connection, showing how eigenvectors associated with AEPs span a subspace of the Laplacian spectrum that governs partition-induced synchronization behavior. This offers a principled reduction of network dynamics, allowing clustered states to be understood in terms of quotient graph projections.

Finding a way to relax is increasingly difficult in our overstimulating, modern society. Chronic stress can have severe psychological and physiological consequences. Music is a promising tool to promote relaxation by lowering heart rate, modulating mood and thoughts, and providing a sense of safety.

Watanabe-Strogatz theory provides a low-dimensional description of identical Kuramoto oscillators via the framework of the Möbius transformation. Here, using the Watanabe-Strogatz theory, we provide a unifying description for a broad class of identical Kuramoto oscillator models with pairwise and higher-order interactions and their corresponding higher harmonics. We show that the dynamics of the Watanabe-Strogatz parameters are the same as those of the mean-field parameters.
