The spatial selection of heterogeneous firms [PDF]
Journal of International Economics, 2010 We show that heterogeneous firms choose different locations in response to market integration. Specifically, decreasing trade costs lead to the gradual agglomeration of efficient firms in the larger country where they have access to a bigger pool of consumers.

Ecological Indicators, 2021 Spatial heterogeneity plays a crucial role in affecting the ecologial processes in natural ecosystems, yet how spatial heterogeneity of herbaceous vegetation in desert-grassland transitional zone varies with increased spatial scale are still poorly known.

Spatial heterogeneity enhances and modulates excitability in a mathematical model of the myometrium [PDF]
, 2013 The muscular layer of the uterus (myometrium) undergoes profound changes in global excitability prior to parturition. Here, a mathematical model of the myocyte network is developed to investigate the hypothesis that spatial heterogeneity is essential to ...

FunSpace: A functional and spatial analytic approach to cell imaging data using entropy measures.
PLoS Computational Biology, 2023 Spatial heterogeneity in the tumor microenvironment (TME) plays a critical role in gaining insights into tumor development and progression. Conventional metrics typically capture the spatial differential between TME cellular patterns by either exploring ...

Species richness-environment relationships of European arthropods at two spatial grains : habitats and countries [PDF]
, 2012 We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy, water-energy dynamics and spatial environmental heterogeneity.

Modelling Spatial Regimes in Farms Technologies [PDF]
, 2017 We exploit the information derived from geographical coordinates to endogenously identify spatial regimes in technologies that are the result of a variety of complex, dynamic interactions among site-specific environmental variables and farmer decision ...

A Bayesian spatial random effects model characterisation of tumour heterogeneity implemented using Markov chain Monte Carlo (MCMC) simulation [PDF]
, 2016 The focus of this study is the development of a statistical modelling procedure for characterising intra-tumour heterogeneity, motivated by recent clinical literature indicating that a variety of tumours exhibit a considerable degree of genetic spatial ...

Spatial Heterogeneity Analysis: Introducing a New Form of Spatial Entropy
Entropy, 2018 Distinguishing and characterizing different landscape patterns have long been the primary concerns of quantitative landscape ecology. Information theory and entropy-related metrics have provided the deepest insights in complex system analysis, and have ...

The spatial and temporal heterogeneity of macrophyte communities in thirty small, temporary ponds over a period of ten years [PDF]
, 2008 Ponds are important habitats within many landscapes because of the diversity of wildlife they support. This arises in part because of the heterogeneity of ecological communities found in neighbouring ponds but this variation has proved difficult to ...
