Cumulated job demands (CJD) was defined as the number of: using pneumatic tools, other vibrating hand tools, hammer, tasks at height, working in adverse climate, pace of working, cold, heat, and noise exposure. Lifetime smoking was reported by 63.8 % of subjects, and 5.9 % initiated ...
Workspace satisfaction: The privacy-communication trade-off in open-plan offices Satisfaction with IEQ changes depending on the degree of workspace enclosure.Occupants of different office layouts have different IEQ priorities.Noise and ... J Kim,RD Dear - 《Journal of Environmental Psychology》 被引...
Noise amplification and ill-convergence of Richardson-Lucy deconvolution Computer algorithms for contrast and resolution enhancement of microscopic images can become derailed. The authors here provide proof is offered that the Richardson-Lucy algorithm turns out to amplify noise in the initial data, wrecki...
It has been well-known since the pioneering work of Claude Shannon in the 1940s that a message transmitted with optimal efficiency over a channel of limited bandwidth is indistinguishable from random noise to a receiver who is unfamiliar with the language in which the message is written. In ...
the measurement noise due to thermal fluctuations has been characterized using fluctuation–dissipation theorems41,44. However, thermal fluctuations are fundamentally different from structural heterogeneities: the former arise uniformly in space and vary in time, and the latter vice versa. Although methods...
Eavesdropping Interference in Wireless Communication Networks Based on Physical Layer Security artificial noise is proposed by combining physical layer security and clustering scenarios to protect the communication security of wireless sensor networks. This... M Chen,Y Chen - 《International Journal of Adva...
Physical-Layer Security Enhancement in Wireless Communication Systems Without any doubt, wireless infrastructures and services have fundamental impacts on every aspect of our lives. Despite of their popularities, wireless communications are vulnerable to various attacks due to the open nature of radio prop...
The physical limits of communication or Why any sufficiently advanced technology is indistinguishable from noise It has been well known since the pioneering work of Claude Shannon in the 1940s that a message transmitted with optimal efficiency over a channel of limite... M Lachmann,MEJ Newman,C...
Our novel receptor interactions could also be integrated with known signalling pathways to infer cellular communication pathways that appear differentially active in diseased states26, which implicated the newly discovered JAML interaction in potentially regulating anti-tumour immunity (Extended Data Fig. 8d...
the signal-to-noise ratio remained the same with the received mixtures at best. In contrast, photonic BSS can recover the communication link without prior assumptions and suppress the interference noise. Figure3a–hillustrates the spectrum and the constellation diagram before and after the BSS process...
