The physiological restorative effects in changing air temperature among various landscape composition of green spaces during summer: Empirical evidence from Chongqing, China

open access: yesEcological Indicators
As vital infrastructures, green spaces provide important places for outdoor activities and social interactions for urban residents. Previous studies have shown that visiting green spaces significantly enhances physiological restorative effect (PRE) on ...

Influenza Surveillance in an Urban Area [PDF]

open access: yesCanadian Journal of Infectious Diseases and Medical Microbiology, 1993
In Houston the yearly influenza epidemics have been defined virologically by community surveillance obtained by testing specimens submitted from patients with acute respiratory illnesses seen by sentinel physicians. Mortality attributed to influenza and pneumonia has increased regularly during the period of intense influenza virus activity, but the ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced 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.

[Assessment of urban location factors from remote sensing]

open access: yes, 2006
Highly-dynamic, explosively and unmanageably growing megacities arise throughout the world. This rapid alteration within the urban environment often results in a lack of reasonable information for city planning, risk management or site selection.

Inferring mobility of care travel behavior from transit smart fare card data

open access: yesJournal of Public Transportation
Existing research underscores substantial gender-based variations in travel behavior on public transit. Studies have concluded that these differences are largely attributable to household responsibilities typically falling disproportionately on women ...

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced 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.

The culture and economics of urban public space design: public and professional perceptions

open access: yes, 2009
Urban public space is once again a ‘hot’ topic and figures strongly in place quality discourse. City spaces are being recycled, reinterpreted and reinvented in a drive for a competitive quality of place.

Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene

open access: yesAdvanced Electronic Materials, EarlyView.
The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Birds and butterflies in Swedish urban and peri-urban habitats [PDF]

open access: yes, 2007
Urbanisation is considered to be one of the largest threats to biodiversity although little is known about the effect of habitat fragmentation on native flora and fauna in urban areas in general, and in Sweden specifically. In this thesis, data have been
