Polydopamine‐Wool Textiles for Sustainable Interfacial Solar Vapor Generation
Advanced Science, EarlyView.A natural wool textile engineered for high solar absorbance and a fast‐wicking structure serves as a highly efficient, single‐layer system for interfacial solar vapor generation (ISVG). This integrated evaporator seamlessly couples rapid water transport with continuous evaporation. Ultimately, this sustainable photothermal design offers a scalable, eco‐

Study of Rail Transit and Urban Spatial Structure Based on Urban Economics [PDF]
, 2015 The spatial changes of utilization intensity of urban lands are decided by the dual substitute relation of transportation costs and rent’s substitute and elements substitute (producer) or consumption substitute (residence). The land use intensity affects

Self-Organizing Maps and the US Urban Spatial Structure [PDF]
This article considers urban spatial structure in US cities using a multi- dimensional approach. We select six key variables (commuting costs, den- sity, employment dispersion/concentration, land-use mix, polycentricity and size) from the urban ...

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.

Search, Wage Posting, and Urban Spatial Structure [PDF]
We develop an urban-search model in which firms post wages. When all workers are identical, the Diamond paradox holds, i.e. there is a unique wage in equilibrium even in the presence of search and spatial frictions.

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.

Urban spatial structure and suburbanisation. The case of the Barcelona Metropolitan [PDF]
The metropolitan spatial structure displays various patterns, sometimes monocentricity and sometimes multicentricity, which seems much more complicated than the exponential density function used in classic works such as Clark (1961), Muth (1969) or Mills
