Summary: The coexistence of heterogeneous devices in wireless networks has led to the development of cross-technology communication (CTC) to improve efficiency and collaboration. Current CTC research focuses on physical-layer CTC and packet-level energy modulation (PLEM), both of which have compatibility or performance issues. In this paper, we propose symbol-level energy modulation (SLEM), a fully compatible CTC method that can be smoothly deployed in commercial wireless networks.

Summary: This study explores an alternative strategy of non-invasive brain delivery of nanoparticles and finds that this method can enhance the neural stimulation effects of transcranial magnetic stimulation (TMS). The use of Tat-SPIONs in combination with TMS shows significant improvement in stroke recovery in rats. Mechanistic studies suggest that the neural stimulation enhancement is mediated by neuroplasticity and magnetoelectric effect, primarily through the binding of Tat-SPIONs to neurons' plasma membranes. This research provides a technological platform for the medical applications of nanoparticles in remote brain stimulation for stroke and other neurological disorders.

Summary: Wireless Sensor Networks (WSN) is an efficient technology in intelligent communication and has been widely used in various applications. This research proposes a Fuzzy Model for Content-Centric Routing (FMCCR) in WSN to address the challenges of heterogeneous data routing. FMCCR achieves better performance by controlling the network topology and using content-centric and fuzzy logic-based routing algorithm for data transmission. Simulation results show that FMCCR reduces energy consumption, improves traffic load distribution, and increases network lifetime compared to previous methods. These results demonstrate the efficiency of FMCCR for real-world scenarios.

Summary: This article presents the design, development, and experimental validation of an inductively-powered four-channel optical neurostimulator system on a chip (SoC), which features on-chip neural recording, temperature monitoring, signal processing, and bidirectional wireless data communication. A biologically-inspired optical stimulation approach is employed to extend the limitations on stimulation pulse-width and frequency while reducing the required on-device storage capacitor size. The article also highlights the enhanced energy efficiency of the stimulator and the utilization of inkjet printing to fabricate custom-designed optical mu lenses for improved light directivity.

Summary: This paper proposes an enhanced Clear Channel Assessment (E-CCA) mechanism to mitigate the cross-technology interference (CTI) in WiFi and ZigBee coexistence networks. The mechanism includes ZShark, which identifies signals within an acceptable time duration, and a MAC layer design that allows a WiFi device to determine channel occupancy even when the detected energy is below the CCA threshold. The performance of ZShark and E-CCA is evaluated through experiments and simulations, demonstrating significant improvement in ZigBee performance.
