Open Space and Urban Sprawl: The Effects of Zoning and Forest Conservation Regulations in Maryland [PDF]
Rapid urbanization enhances the desirability of policies for preserving open space but policies intended to preserve open space may extend the urban boundary and create leapfrog development.

Advanced Science, EarlyView.Recent advances in metasurface‐enabled low‐observable technologies are reviewed from the perspective of cross‐scale material–structure synergy. Electromagnetic, thermal, optical, and acoustic stealth are highlighted together with dynamic tuning, programmable coding, data‐driven inverse design, artificial intelligence, multispectral compatibility, and ...

A Taste for Trips out of Town: Urban Sprawl and Access to Open Space [PDF]
Residential development at the urban fringe raises the cost of trips to open space. We derive a simple expression for the tax that internalizes this effect of sprawl in a monocentric city andapply it using survey data on recreational activity.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Advanced Electronic Materials, EarlyView.Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Open space preservation in an urbanization context [PDF]
Journal of Regional Science, 2019 AbstractThe objective of this paper is to address the question of open space preservation in an urbanization context. We study the possibility of preserving two different types of open spaces, namely, large open spaces at cities’ outskirts and small intraurban open spaces.

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Chinese Trade Competition and Rural Mexican Migration
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT China's accession to the World Trade Organization in 2001 reshaped global trade, reducing U.S. demand for Mexican manufactured goods and weakening Mexico's manufacturing employment. This study estimates how this trade‐induced decline affected migration and employment decisions among rural Mexicans.
