Inequality is rising where social network segregation interacts with urban topology
Nature Communications, 2021 Not much is known about the joint relationships between social network structure, urban geography, and inequality. Here, the authors analyze an online social network and find that the fragmentation of social networks is significantly higher in towns in ...

Growth and Agglomeration [PDF]
International Economic Review, 2001 This article presents a model in which growth and geographic agglomeration of economic activities are mutually self‐reinforcing processes. Economic agglomeration in one region spurs growth because it reduces the cost of innovation in that region through a pecuniary externality due to transaction costs.

Is Agglomeration Desirable? [PDF]
Annals of Economics and Statistics, 2009 By introducing heterogeneity between high-skilled mobile and low-skill immobile workers in a model with land rent and commuting costs we develop a new model in the field of the new model in the field of the new economic geography. This model, which can reveal a dispersion-agglomeration-dispersion configuration when trade gets freer, is used to compare ...

Estimation of the unfrozen water content of saturated sandstones by ultrasonic velocity
International Journal of Mining Science and Technology, 2023 The unfrozen water content (UWC) of rocks at low temperature is an important index for evaluating the stability of the rock engineering in cold regions and artificial freezing engineering.

Agglomerates of nanoparticles [PDF]
Beilstein Journal of Nanotechnology, 2020 Nanoparticles tend to agglomerate. The process of agglomeration is ruled by thermodynamics. Depending on the sign of the enthalpy of interaction, ensembles consist of (repelling) poorly agglomerated or (attracting) highly agglomerated particles. For these two cases different distribution functions for the agglomerates were found.
