High deployment costs, safety risks, and time delays restrict traditional track detection methods in high-speed railways.Therefore, approaches based on optical sensors have become the most remarkable strategy in terms of deployment cost and Starters real-time performance.Owing to the large amount of data obtained by sensors, it has been proven that
Pathogenic Neisseria meningitidis isolates contain a polysaccharide capsule that is the main virulence determinant for this bacterium.Thirteen capsular polysaccharides have been described, and nuclear magnetic resonance spectroscopy has enabled determination of the structure of capsular polysaccharides responsible for serogroup specificity.Molecula
