Potential and Spatial Structure of Population [PDF]
The goal of this work is to suggest a mechanism explaining different spatial patterns of residential locations. The basic idea is counterbalance of centripetal and centrifugal forces. This paper complements the previous author's works in this area.

Urban spatial structure: an interaction between employment and built-up volumes
, 2015 This paper employs socioeconomic and remote sensing data to develop a novel approach to analysing the morphological urban spatial structure in select German city-regions.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer
Molecular Oncology, EarlyView.PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Modeling at the interface of ecology and epidemiology [PDF]
Computational Ecology and Software, 2015 We briefly present a synthesis of theoretical models in eco-epidemiology which merges the fields of ecology and epidemics. In particular we discuss the role of parasites/pathogens in community assembly formation and species coexistence, as well as the ...

Spatial Random Sampling: A Structure-Preserving Data Sketching Tool
, 2017 Random column sampling is not guaranteed to yield data sketches that preserve the underlying structures of the data and may not sample sufficiently from less-populated data clusters.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The spatial structure of the financial development in Brazil [PDF]
This paper explores the financial development in Brazil. It focuses on the impacts of the development level of a municipality’s financial system over its neighborhood, under the light of the Central Place Theory. Using a GMM estimator for a spatial panel

Monocentric or Polycentric? The Urban Spatial Structure of Employment in Beijing
, 2015 The spatial structure of Beijing has changed dramatically since the reforms of the late 1970s. It is not clear, however, whether these changes have been sufficient to transform the city’s monocentric spatial structure into a polycentric one.

The idiosyncrasy of spatial structure in bacterial competition
BMC Research Notes, 2015 BackgroundThe spatial structure of a habitat can have a strong impact on community dynamics. Different experimental approaches exist to explore the effect of spatial structure on bacterial communities.

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
