Spatial Heterogeneity of Autoinducer Regulation Systems [PDF]
Sensors, 2012 Autoinducer signals enable coordinated behaviour of bacterial populations, a phenomenon originally described as quorum sensing. Autoinducer systems are often controlled by environmental substances as nutrients or secondary metabolites (signals) from ...

Spatial Dynamics with Heterogeneity
SIAM Journal on Applied Mathematics, 2023 Spatial systems with heterogeneities are ubiquitous in nature, from precipitation, temperature and soil gradients controlling vegetation growth to morphogen gradients controlling gene expression in embryos. Such systems, generally described by nonlinear dynamical systems, often display complex parameter dependence and exhibit bifurcations. The dynamics

Spatial heterogeneity in medulloblastoma [PDF]
Nature Genetics, 2017 Spatial heterogeneity of transcriptional and genetic markers between physically isolated biopsies of a single tumor poses major barriers to the identification of biomarkers and the development of targeted therapies that will be effective against the entire tumor.

Heterogeneous timescales are spatially represented [PDF]
Frontiers in Psychology, 2014 There is little doubt that cognitive processes involved in perceiving and comparing the duration of the sounds played by a musical instrument are very different from those involved, for instance, in recalling when our latest holidays took place. However, despite their clear difference, we ascribe both processes to the time domain, either in the form of

Spatial localization in heterogeneous systems [PDF]
Physical Review E, 2014 We study spatial localization in the generalized Swift-Hohenberg equation with either quadratic-cubic or cubic-quintic nonlinearity subject to spatially heterogeneous forcing. Different types of forcing (sinusoidal or Gaussian) with different spatial scales are considered and the corresponding localized snaking structures are computed.

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.

Spatial Heterogeneity in Bistable Figure-Ground Perception
i-Perception, 2020 The appearance of visual objects varies substantially across the visual field. Could such spatial heterogeneity be due to undersampling of the visual field by neurons selective for stimulus categories?

Inference on spatial heterogeneity in tumor microenvironment using spatial transcriptomics data
Computational and Systems Oncology, 2022 In the tumor microenvironment (TME), functional interactions among tumor, immune, and stromal cells and the extracellular matrix play key roles in tumor progression, invasion, immune modulation, and response to treatment.
