A review on shear jamming [PDF]
Physics Reports, Volume 1038, 2 November 2023, Pages 1-18, 2023 Jamming is a ubiquitous phenomenon that appears in many soft matter systems, including granular materials, foams, colloidal suspensions, emulsions, polymers, and cells -- when jamming occurs, the system undergoes a transition from flow-like to solid-like states.

IEEE Transactions on Information Forensics and Security, 2021 In this paper, beam-domain (BD) anti-jamming transmission in a downlink massive multiple-input multiple-output (MIMO) system is investigated. A smart jammer with multiple antennas attempts to interfere with the signal reception of users with the desired ...

Incentive Jamming-Based Secure Routing in Decentralized Internet of Things
IEEE Internet of Things Journal, 2021 This article focuses on the secure routing problem in the decentralized Internet of Things (IoT). We consider a typical decentralized IoT scenario composed of peer legitimate devices, unauthorized devices (eavesdroppers), and selfish helper jamming ...

Radar Anti-Jamming Decision-Making Method Based on DDPG-MADDPG Algorithm
Remote Sensing, 2023 In the face of smart and varied jamming, intelligent radar anti-jamming technologies are urgently needed. Due to the variety of radar electronic counter-countermeasures (ECCMs), it is necessary to efficiently optimize ECCMs in the high-dimensional ...

Proceedings of the National Academy of Sciences, 2016 Diverse forms of matter around us can simply be classified as those that flow and those that don’t and exhibit rigidity, a resistance to deform when a force is applied. This elementary distinction informs our ability to comprehend their properties and to manipulate them. It is easy enough to pick up a spoon, a solid that pushes back against our fingers,
