In this paper we present the challenging problem of realizing the Urban Computing vision and in particular we describe the requirements for future mobility management systems. We show that novel multi-disciplinary ideas are required to address the Urban Computing challenge and that only partial solutions can be found today. The Urban Computing challenge is open and many efforts are needed to

We investigate how core arguments are coded in case-marking Indo-European languages. Core arguments are a central concept in Universal Dependencies, yet it is sometimes difficult to match against terminologies traditionally used for individual languages. We review the methodology described in (Andrews, 2007), and include brief definitions of some basic terms. Statistics from 26 UD treebanks sho...

The pressures for closer alignment between physicians and hospitals in both rural and urban areas are increasing. This study empirically specifies independent dimensions of physician and clinical integration and compares the extent to which such activities are practiced between rural and urban hospitals and among rural hospitals in different organizational and market contexts. Results suggest t...

The staff of a heart and circulatory disease program of a State department of health conducted a special project at a city hospital which showed that a well-organized treatment and education program for patients with congestive heart failure increased the patient's knowledge of his disease, medication, and diet as well as his adherence to a prescribed regimen, and significantly reduced the numb...

Urban sprawl has been at the center of current debate on urban structure. Compared to the rich literature on urban sprawl in Western cities, relatively little is known about whether Chinese urban expansion is excessive or inefficient. This paper provides an integrated analysis of two seemingly contradictory phenomena in China’s urban development in recent two decades, namely development zones a...

Sustainable development is a key component in urban studies. Earth Observation (EO) can play a valuable role in sustainable urban development and planning, since it represents a powerful data source with the potential to provide a number of relevant urban sustainability indicators. To this end, in this paper we propose a conceptual list of EO-based indicators capable of supporting urban plannin...

We investigate the spin correlations in top quark pair production near threshold at the e−e+ linear collider. Comparing with the results above the threshold region, we find that near the threshold region the off-diagonal basis, the optimized decomposition of the top quark spins above the threshold region, does not exist, and the beamline basis is the optimal basis, in which there are the domina...

Urban ecosystem health evaluation can assist in sustainable ecological management at a regional level. This study examined urban agglomeration ecosystem health in the middle reaches of the Yangtze River with entropy weight and extension theories. The model overcomes information omissions and subjectivity problems in the evaluation process of urban ecosystem health. Results showed that human cap...

Objective: Our objective was to pilot collaborations between two urban farms with two corner stores to increase access to fresh produce in low-income neighbourhoods. Design: We conducted a pre–post evaluation of two farm–store collaborations using quantitative distribution and sales data. Using semi-structured interviews, we qualitatively assessed feasibility of implementation and collaboration...

It is a challenge to specify unambiguous distance (UD) in a phase-based ranging system with hopping frequencies (PRSHF). In this letter, we propose to characterize the UD in a PRSHF by the probability that it takes on its maximum value. We obtain a very simple and elegant expression of the probability with growth estimation techniques from analytic number theory. It is revealed that the UD in a...
