The Possibilities for Deployment Eco-Friendly Indoor Wireless Networks Based on LiFi Technology
Proceedings of the International Conference on Applied Innovations in IT, 2020 Recently, traffic demand for wireless data has increased the need for extending the spectrum to transmit numerous signals. However, the bandwidth of radio waves has been scrunching in the last few years with tremendous development of technology such as ...

AIP Conference Proceedings, 2000 The southern supernova remnant (SNR)W28 was observed in 1994 and 1995 by the CANGAROO 3.8m telescope in a search formulti-TeV gamma ray emission, using the Cerenkov imaging technique. We obtained upper limits for a variety of point-like and extended features within a +-1 degree-region and briefly discuss these results, together with that of EGRET ...

Advanced Healthcare Materials, EarlyView.Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...

Advanced Materials, EarlyView.Coupled materials design enables a monolithic fiber that integrates complementary sensing regimes into a single wearable strand. By preserving informative signal features across subtle physiological deformation, large body motion, and mixed mechanical inputs, the dual‐gradient architecture generates synchronized, less redundant outputs that improve ...

Finite-SNR diversity-multiplexing trade-off of inter-vehicular cooperative diversity protocols
, 2014 The finite-signal-to-noise ratio (SNR) diversity-multiplexing trade-off (DMT) of cooperative diversity protocols are investigated in vehicular networks based on cascaded Rayleigh fading. Lower bounds of DMT at finite SNR for orthogonal and non-orthogonal
