Current brain‐inspired computing chips require complex additional circuits to operate effectively, making them bulky and inefficient. We have created a single adjustable artificial neuron device made from MoS2 that can dynamically modulate its behavior on demand, eliminating the need for extra circuits and enabling it to process different types of ...

Fault Tolerant Stabilizability of Multi-Hop Control Networks
A Multi-hop Control Network (MCN) consists of a plant where the communication between sensor, actuator and computational unit is supported by a wireless multi-hop communication network, and data flow is performed using scheduling and routing of sensing ...

All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Maximum zeros scheduling for satellite switch TDMA
A scheduling technique suitable for pre-assignment in satellite switched time division multiple access (SS-TDMA) systems is presented. As many uninterrupted bursts as are feasible are transmitted per configuration of the switch matrix. For small switch matrices (up to 6 × 6) this technique usually requires fewer reconfigurations than previous methods.

A Review of Software for Designing and Operating Quantum Networks
A quantum network can be organized following a three‐plane abstraction: infrastructure, logical, and control. A taxonomy of the network functions of the control plane is proposed, and the state of the art in software for quantum networks is discussed. A guide for future directions on software development is provided.

The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

Communication‐Security Co‐Design for Federated Learning in Grant‐Free NOMA IoT Networks
This article presents SA‐PPO, a Security‐Aware Proximal Policy Optimisation framework for federated learning over grant‐free NOMA (non‐orthogonal multiple access) in IoT networks. By jointly optimising access control, resource allocation, and trust‐weighted aggregation using cross‐layer indicators, SA‐PPO enhances both communication reliability and ...
