A Convergent Route to Enantiomers of the Bicyclic Monosaccharide Bradyrhizose Leads to Insight into the Bioactivity of an Immunologically Silent Lipopolysaccharide
Download2019-01-27
Claude Larrivée Aboussafy, Lotte Bettina Anderson Gersby, Antonio Molinaro, Mari-Anne Newman, Todd L. Lowary
The synthesis of bradyrhizose, the monosaccharide component of the lipopolysaccharide O-antigen of the nitrogen-fixing bacteria Bradyrhizobium sp. BTAi1 and sp. ORS278, has been achieved in 25 steps in an overall yield of 6% using myo-inositol and ethyl propiolate as the starting materials. The...

A Data Driven Approach to Creating a Traffic Sign Asset Inventory using Remote Sensing Technology
DownloadSpring 2019
Traffic signs play a critical role in the safety and efficiency of any roadway, but with limited information on the current status of traffic sign inventories, the placement and condition of traffic signs goes largely unchecked. Therefore, the collection of a complete traffic sign inventory (TSI)...

A decision support framework for concurrent multi-DFX implementation to optimize the machine design process
DownloadSpring 2019
Industry 4.0 has sparked rapid changes in the manufacturing and construction sectors, leading to a major shift in how prefab construction machines are designed and manufactured in a concurrent engineering environment. Design for X (DFX) is one of the most effective methods for implementing in...

A drive for better air service: How air service imbalances across neighboring regions integrate air and highway demands
Download2019-11-07
Between 2000-2010, newly merged U.S. airlines decreased service to airports in small and midsized metropolitan regions, opting to consolidate their operations at high-value airport hubs (passenger transfer points). At this point travelers living in small and mid-sized regions likely began...
