Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China

Advanced Science, EarlyView.
Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...

Long‐Term Ambient Benzene Exposure and Brain Disorders Among Urban Adults: Effect Modification by Genetic Susceptibility and Potential Mediation by Plasma Proteins

Advanced Science, EarlyView.
Low‐level ambient benzene exposure is associated with increased risks of multiple brain disorders in urban adults. Genetic susceptibility modifies these associations, while plasma proteomics points to potential biological pathways linking benzene exposure to adverse brain health.

Retail spatial organisation and the physical city: bridging retail geography and urban morphology

Belgeo
The spatial organization of stores plays a crucial role in the production and development of the urban form while, at the same time, being strongly influenced from the physical constraints of the latter. Yet the connection between retail distribution and

Solar‐Driven Bifunctional Adsorption‐Storage Films for Ultra‐Fast Dehumidification and Freshwater Supply in Low‐carbon Buildings

Advanced Science, EarlyView.
Bifunctional adsorption‐storage films enable autonomous indoor humidity regulation and freshwater harvesting, rapidly decreasing relative humidity from 90.7% to 21.6% within one hour while producing 1.1 kg·m−2·day−1 of water, offering a passive route towards energy‐efficient humidity control and sustainable indoor environments. ABSTRACT Indoor humidity

Urban expansion: from compact to fragmented form

Acta Scientiarum: Technology, 2019
The new urban order in the territorialization of cities, in general, is based on the principles of an ever more fragmented and dispersed growth across the territory.

Urban Form and Sustainable development [PDF]

, 2011
The links between urban development and the environment are numerous and complex. If natural and agriculture lands may attract households, the very process of urban development impacts on the environment in multiple ways : water and air pollution, biodiversity loss, greenhouse gaz emission by the transport of people and commodities, etc.

Testing urban forms: city, control and ‘urban violence’ in France

, 2006
Le concept de violence urbaine impute une catégorie d'actes à une catégorie d'espaces. L'émergence de ce concept s'inscrit dans une dynamique historique particulière des politiques publiques françaises qui a vu un recentrage de la question sociale ("les travailleurs exploités) sur une "nouvelle question urbaine" ("les zones d'exclusion"). L'analyse des

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

Advanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...
