The Economic, Fiscal and Developmental Impacts of the North Texas Tollway Authority: A 40-Year Perspective (open access)

The Economic, Fiscal and Developmental Impacts of the North Texas Tollway Authority: A 40-Year Perspective

This report by the University of North Texas Center for Economic Development and Research looks at the North Texas Tollway Authority (NTTA) as a regional economic generator. It first examines the impacts from the NTTA's construction spending on the Dallas North Tollway (DNT) and the President George Bush Turnpike (PGBT). Second, it quantifies the economic and fiscal impacts from the NTTA's recurring operational spending. Third, it looks at the value of all the residential and commercial development that has ocurred along the DNT and PGBT corridors over the past 30-40 years as well as the annual tax revenues generated by this development. Finally, it discusses how NTTA's projects have helped improve mobility in the North Texas region.

Object-Oriented Canopy Gap Extraction from UAV Images Based on Edge Enhancement

Article describes the efficient and accurate identification of canopy gaps is the basis of forest ecosystem research, which is of great significance to further forest monitoring and management. One major limitation of the traditional methods of remote sensing to map canopy gaps is that they cannot finely extract the complex edges of canopy gaps in mountainous areas. The authors proposed an object-oriented classification method that integrates multi-source information.

Multimodal switching of a redox-active macrocycle (open access)

Multimodal switching of a redox-active macrocycle

This article looks at molecules that can exist in multiple states with the possibility of toggling between those states based on different stimuli. They have potential for use in molecular switching or sensing applications. The coupling of two different oxidation states with two different charge-transfer states within one macrocyclic scaffold delivers up to five different optical outputs. This molecular switching manifold exploits intramolecular coupling of multiple redox active substituents within a single molecule.
