Article Abstract
Achieving perfect synchronization in a complex network, specially in the presence of higher-order interactions (HOIs) at a targeted point in the parameter space, is an interesting, yet challenging task. Here we present a theoretical framework to achieve the same under the paradigm of the Sakaguchi-Kuramoto (SK) model. We analytically derive a frequency set to achieve perfect synchrony at some desired point in a complex network of SK oscillators with higher-order interactions. Considering the SK model with HOIs on top of the scale-free, random, and small world networks, we perform extensive numerical simulations to verify the proposed theory. Numerical simulations show that the analytically derived frequency set not only provides stable perfect synchronization in the network at a desired point but also proves to be very effective in achieving a high level of synchronization around it compared to the other choices of frequency sets. The stability and the robustness of the perfect synchronization state of the system are determined using the low-dimensional reduction of the network and by introducing a Gaussian noise around the derived frequency set, respectively.

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.

The demand for highly sensitive and accurate sensors has grown significantly, particularly in the field of Micro-Electro-Mechanical Systems technology. Mode-localized sensors based on weakly coupled resonators have garnered attention for their high sensitivity through amplitude ratio outputs. However, when measuring multiple signals by weakly coupled resonators, different signals can interfere with each other, causing high cross-sensitivity.

Background And Objectives: Routine cerebrospinal fluid (CSF) sampling in patients with external ventricular drains (EVDs) is a standard neurosurgical practice to screen for infections and steer CSF diversion management. Although proximal CSF sampling (through CSF aspiration from the tubing) permits analysis of fresh intraventricular CSF, it carries a risk of iatrogenic infection, hemorrhage, and catheter blockage, contrary to distal CSF sampling (collected passively from the fluid chamber). This study assesses the agreement in CSF characteristics obtained through proximal and distal sampling in EVD patients.

In order to realize robust communication in complicated interference electromagnetic environments, an intelligent transmitter design is proposed in this paper, where an auxiliary wideband receiver senses the electromagnetic distribution information in a wide bandwidth range to decide the optimal working frequency. One of the key issues is suppressing the self-interference of high-power transmitter signals to the co-platform wideband sensing receiver. Due to the multipath effect of the self-interference channel, perfect time synchronization of self-interference signals is not achievable, which reduces the interference cancelation performance of the co-platform.
