Regional differences in spatial flexibility : long commutes and job related migration intentions in the Netherlands [PDF]

open access: yes, 2016
Spatial flexibility of the workforce is important in clearing regional labour markets. Workers’ spatial flexibility is limited and many European countries are developing policies to enhance the spatial flexibility of the labour force.

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.

URBAN STRUCTURE: ITS ROLE IN URBAN GROWTH, NET NEW BUSINESS FORMATION AND INDUSTRIAL CHURN [PDF]

open access: yes
Cities are the “engines of growth” because entrepreneurial and cre-ative activities are concentrated in cities. This suggests that cities grow by host-ing new businesses and “churning” industries advantageously.

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 spatial syntax of urban segregation [PDF]

open access: yes, 2007
Space syntax is a set of theories and techniques about buildings and cities and how they function, rooted in a theory of society and space that originated at the UCL Bartlett School of Graduate Studies in the 1970s. The ability of space syntax methods to

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 ...

Assessing Household Welfare in Response to Rising Food Prices in The Gambia

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines how rising food prices affected household welfare in The Gambia using nationally representative data from the 2015/16 Integrated Household Survey (IHS‐3). The analysis reflects household consumption behavior and market conditions prevailing during that period and provides a structural benchmark for understanding ...
