Spatially embedded dynamics and complexity
, 2010 To gain a deeper understanding of the impact of spatial embedding on the dynamics of complex systems we employ a measure of interaction complexity developed within neuroscience using the tools of statistical information theory. We apply this measure to a

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 complexity of logical theories
Theoretical Computer Science, 1980 AbstractIn this paper we introduce a method of encoding the computation of an alternating TM into a logical theory. The efficiency of the embedding we give together with the decision procedures, using Ehrenfencht games, which have been developed over the past few years, yield precise lower bounds for many decidable theories.

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Complexity and stability of ecological networks: a review of the theory
Population Ecology, 2018 Our planet is changing at paces never observed before. Species extinction is happening at faster rates than ever, greatly exceeding the five mass extinctions in the fossil record.

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

A complexity theory-informed COPC approach to evaluation of mining health programmes
African Journal of Primary Health Care & Family MedicineBackground: Conventional evaluation approaches are often designed for predictable, linear systems and fail to capture the non-linear dynamics of complex community health interventions.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Cryptology and Complexity Theories [PDF]
, 2007 Complexity Theories have recently been proposed as a basis for evaluation of crypto machine performance. They are compared to Shannon's model. They shed a new highlight on randomness notion. But it is stressed that the statistical point of view remains the more secure.
