Abstract

Metro systems are vital to our daily lives, but they face safety or reliability challenges, such as criminal activities or infrastructure disruptions, respectively. Real-time threat detection and analysis are crucial to ensure their safety and reliability. Although many existing systems use Twitter to detect metro-related threats or events in real-time, they have limitations in event analysis and system maintenance. Specifically, they cannot analyze event development, or prioritize events from numerous tweets. Besides, their users are required to continuously monitor system notifications, use inefficient content retrieval methods, and perform detailed system maintenance. We addressed those issues by developing the MetroScope system, a real-time threat/event detection system applied to Washington D.C. metro system. MetroScope can automatically analyze event development, prioritize events based on urgency, send emergency notifications via emails, provide efficient content retrieval, and self-maintain the system. Our MetroScope system is now available at http://orion.nvc.cs.vt.edu:5000/, with a video (https://www.youtube.com/watch?v=vKIK9M60-J8) introducing its features and instructions. MetroScope is a significant advancement in enhancing the safety and reliability of metro systems.

5. Alternative splicing caused by RNA secondary structure

Author

Solnick, David

Abstract

mRNA precursors with stable hairpins were constructed by inserting inverted repeats into an adenovirus transcriptional template that encoded the three late leader exons. When the loop of the hairpin contained the second exon and the flanking splice sites, most of the RNA spliced in vitro had the first exon joined directly to the third exon. The remainder was spliced normally. The same types of alternatively spliced RNAs were formed when a similar template was introduced into HeLa cells by transfection. Thus both in extracts and in cells, an exon became optional when sequestered in a hairpin loop. Perhaps a related mechanism creates the alternative splicing patterns of complex transcription units.
