In Wigs order to solve the problem of multi-tag anti-collision in radio frequency identification systems, a multi-tag anti-collision protocol based on 8-ary adaptive pruning query tree is proposed in this article.According to Manchester code, the highest collision bit can be detected.In the process of tag identification, the protocol only locks the
Sunscreens Noise-like square pulses (NLSPs) have been experimentally investigated in both normal and anomalous dispersion regimes.A chirped fiber Bragg grating (CFBG) has been employed as a dispersion management element in the compact linear-cavity mode-locked Yb-doped fiber laser.The net cavity dispersion could be switched from large anomalous dis
BACKGROUND: Eosinophilic meningitis (angiostrongyliasis) caused by Angiostrongylus cantonensis is emerging in mainland China.However, the distribution of A.cantonensis and its intermediate host snails, and the role of two invasive snail species Bridle in the emergence of angiostrongyliasis, are not well understood.METHODOLOGY/PRINCIPAL FINDINGS: A
Specific chromatin immunoprecipitation of salt-fractionated infected cell extracts has demonstrated that the CCCTC-binding factor (CTCF), a highly conserved, 11-zinc-finger DNA-binding protein with known roles in cellular and viral genome organization and gene expression, specifically binds the genome of Minute Virus of Mice (MVM).Mutations that di
