Evaluation of the Valley Transportation Authority’s DO IT! Program A “Ladders of Opportunity Initiative” Program Funded by the Federal Transit Administration [PDF]

open access: yes, 2018
The U.S. Department of Transportation has increasingly demonstrated interest in developing programs that will enhance the workforce capacity of future transportation systems. To that end, the Department sponsored the 2015 Innovative Public Transportation

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Measuring the Performance of Livability Programs, MTI Report 12-06 [PDF]

open access: yes, 2013
This report analyzes the performance measurement processes adopted by five large “livability” programs throughout the United States. It compares and contrasts these programs by examining existing research in performance measurement methods.

Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

open access: yesAdvanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

A Decision-Support Framework For Using Value Capture to Fund Public Transit: Lessons From Project-Specific Analyses, Research Report 11-14 [PDF]

open access: yes, 2012
Local and state governments provide 75 percent of transit funds in the United States. With all levels of governments under significant fiscal stress, any new transit funding mechanism is welcome. Value capture (VC) is one such mechanism.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Interpreting Regional Functions Around Urban Rail Stations by Integrating Dockless Bike Sharing and POI Patterns: Case Study of Beijing, China

open access: yesUrban Science
Identifying area functions around urban rail transit (URT) stations is crucial for optimizing urban planning and infrastructure allocation. Traditional methods relying on static land-use data fail to capture dynamic human–environment interactions, while ...

Housing and Mobility Toolkit for San Mateo County [PDF]

open access: yes, 2019
Since the end of the Great Recession, San Mateo County has attracted new workers at a record rate without building anywhere near enough housing. This jobs-housing imbalance drives the cost of housing up and forces many moderate and lower-income employees
