A Novel Anti-Jamming Decision-Making Algorithm Based on Knowledge Graph Technology
Applied Sciences, 2022 Wireless communications are increasingly vulnerable to malicious jamming attacks due to the inherent openness and broadcast nature. In this regard, a novel anti-jamming scheme based on knowledge graph is proposed in this paper, where the knowledge graph ...

M/C Journal, 2006 ‘Jam’ enjoys a varied set of associations. It’s a responsive term that reflects shifts in technologies of all sorts – from the kitchen to the web and just about everything in between. Over the past century, associations of jam, jamming and being jammed have collided with and guided popular culture in innumerable ways ...

Jamming with Tunable Roughness [PDF]
Physical Review Letters, 2020 We introduce a new model to study the effect of surface roughness on the jamming transition. By performing numerical simulations, we show that for a smooth surface, the jamming transition density and the contact number at the transition point both increase upon increasing asphericity, as for ellipsoids and spherocylinders.

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Overview of Radar Jamming Waveform Design
Remote SensingRadar jamming waveform design is a vital part of radar jamming. Over seven to eight decades of evolution, the field has transitioned from noise signal design to coherent jamming signal design, resulting in a multitude of complex jamming styles capable of

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion
FEBS Open Bio, EarlyView.Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

Quasi-Coherent Noise Jamming to LFM Radar Based on Pseudo-random Sequence Phase-modulation [PDF]
Radioengineering, 2015 A novel quasi-coherent noise jamming method is proposed against linear frequency modulation (LFM) signal and pulse compression radar. Based on the structure of digital radio frequency memory (DRFM), the jamming signal is acquired by the pseudo-random ...
