Urban Gravity: a Model for Intercity Telecommunication Flows

城际流动性揭示城市系统的双曲几何

Intercity mobility reveals the hyperbolic geometry of city systems

研究通过双曲几何模型揭示城市系统中层级与接近度的交互关系，验证了12个全国城际流动性数据集，发现城市层级自下而上形成，其 hinterland 关系呈现非平稳特性。

演变的空间时间模式与死亡外部原因的城市规模效应

Evolving spatiotemporal patterns and urban scaling of deaths from external causes

研究通过分析巴西城市近三十年的死亡数据，发现外部死亡原因的规模效应随时间和空间变化，揭示了城市规模与死亡率之间的复杂关系。

New parameter-free mobility model: Opportunity priority selection model

Predicting human mobility patterns has many practical applications in urban planning, traffic engineering, infectious disease epidemiology, emergency management and location-based services. Developing a universal model capable of accurately predicting the mobility fluxes between locations is a fundamental and challenging problem in regional economics and transportation science. Here, we propose a new parameter-free model named opportunity priority selection model as an alternative in human mobility prediction. The basic assumption of the model is that an individual will select destination loca…

通过手机数据验证城市标度律：对巴西最大城市的大陆尺度分析

Validating Urban Scaling Laws through Mobile Phone Data: A Continental-Scale Analysis of Brazil's Largest Cities

本研究利用巴西100个最大城市的31亿条手机通话记录，在大陆尺度上验证了城市标度律，发现通信与出行呈超线性增长，GDP超线性标度而人均天线需求呈次线性标度，揭示了通信与流动性对城市社会经济格局的塑造作用。

Reconstructing commuters network using machine learning and urban indicators

Human mobility has a significant impact on several layers of society, from infrastructural planning and economics to the spread of diseases and crime. Representing the system as a complex network, in which nodes are assigned to regions (e.g., a city) and links indicate the flow of people between two of them, physics-inspired models have been proposed to quantify the number of people migrating from one city to the other. Despite the advances made by these models, our ability to predict the number of commuters and reconstruct mobility networks remains limited. Here, we propose an alternative app…

Living in Living Cities

This paper presents an overview of current and potential applications of living technology to some urban problems. Living technology can be described as technology that exhibits the core features of living systems. These features can be useful to solve dynamic problems. In particular, urban problems concerning mobility, logistics, telecommunications, governance, safety, sustainability, and society and culture are presented, while solutions involving living technology are reviewed. A methodology for developing living technology is mentioned, while supraoptimal public transportation systems are …
