Agrarian Structures, Urbanization, and Inequality [PDF]
World Development, 2016 This study examines the impact of agrarian structures on income inequality over the long run. First, it exhibits the relationship between land and income distribution by developing a theoretical model based on Harris and Todaro (1970) and Lewis (1954).

Advanced Materials Technologies, EarlyView.A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...

Advanced Robotics Research, EarlyView.Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Urban Structure and Suburban Selectivity [PDF]
Demography, 1964 Se informa respecto a los resultados de dos estudios sobre “selectividad suburbana.” El primero es un estudio longitudinal en su orientacon y examina la medida en que las grandes ciudades y sus suburbios estaban tendiendo a “polarizarse” alrededor de lineas de clase entre los anos 1940 y 1960. Nueve de las diez areas metropolitanas mayores exhibian una

Advanced Robotics Research, EarlyView.Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Between information systems and physical structure of the city: New causes of climate changes [PDF]
Arhitektura i Urbanizam, 2011 Because of the frequent and significant spatial transformations, an increasing climate change regime in urban areas occurs. In this paper a comprehensive reflection on these changes is analyzed, concerning one of the major causes - the social ...
