Imaging Hallmarks of the Tumor Microenvironment in Glioblastoma Progression
Frontiers in Oncology, 2021 Glioblastoma progression involves multifaceted changes in vascularity, cellularity, and metabolism. Capturing such complexities of the tumor niche, from the tumor core to the periphery, by magnetic resonance imaging (MRI) and spectroscopic imaging (MRSI)

The core-periphery model with three regions [PDF]
Papers in Regional Science, 2009 We study a 3-region core-periphery model à la Krugman and compare our results with those of the standard 2-region model. The conditions for the stability of the dispersion and concentration configurations are established. Like in the 2-region model, dispersion and concentration can be simultaneously stable.

Resource effect in the Core–Periphery model
Spatial Economic Analysis, 2019 This paper develops an extension of Krugman’s Core–Periphery (CP) model by considering a competitive primary sector that extracts a renewable natural resource. The dynamics of the resource give rise to a new dispersion force: the resource effect. If primary goods are not tradable, lower trade costs boost dispersion, and the agglomeration–dispersion ...
