Quarterly Journal of the Royal Meteorological Society, EarlyView.We quantified the causal effect (CE) of linkages between four monthly climate indices ENSO, SMHP, RWC, and MHC for 1940–2022 with a time lag of one month. The results show CE values from (1) ENSO to SMHP of −0.33$$ -0.33 $$ to −0.44$$ -0.44 $$ (i.e., a one standard deviation (SD) increase in ENSO causes a decrease in SMHP of −0.33$$ -0.33 $$ to −0.44$$

Corrosion CommunicationsA novel nonlinear corrosion at the three-phase interface of corundum refractory with CaO-Al2O3-SiO2 slag was identified as a Turing pattern phenomenon caused by auto-catalytic reactions involving free radicals Ca·+ and O2·-.

Padrões de Turing em sistemas químicos
Química Nova, 2016 Spontaneous pattern formation in reaction-diffusion systems was theoretically proposed by Alan M. Turing in 1952. His breakthrough conceptions of chemical self-organization were able to explain how patterns emerge in nature and the symmetry breaking ...

Turing Patterns in Deserts [PDF]
, 2012 Self-organised patterns of vegetation are a characteristic feature of many semi-arid regions. In particular, banded vegetation is typical on hillsides. Mathematical modelling is widely used to study these banded patterns, because there are no laboratory replicates.

Biotechnical Multiscale Engineering of Scaffolds for Stem Cell and Organoid Research
Small, EarlyView.Biotechnical multiscale engineering consideration of geometric and structural parameters, which is called biotechnical multiscale engineering, has an influence on stem cell development and organogenesis comparable to that of molecular genetics and biochemical parameters.

Turing patterns with Turing machines: emergence and low-level structure formation [PDF]
Natural Computing, 2013 Despite having advanced a reaction-diffusion model of ODE's in his 1952 paper on morphogenesis, reflecting his interest in mathematical biology, Alan Turing has never been considered to have approached a definition of Cellular Automata. However, his treatment of morphogenesis, and in particular a difficulty he identified relating to the uneven ...

Field test of assumptions for using line transect distance sampling on rock ptarmigan
Wildlife Biology, EarlyView.Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

eLife, 2016 The Turing reaction-diffusion model explains how identical cells can self-organize to form spatial patterns. It has been suggested that extracellular signaling molecules with different diffusion coefficients underlie this model, but the contribution of ...

Pattern formation driven by cross--diffusion in a 2D domain
, 2012 In this work we investigate the process of pattern formation in a two dimensional domain for a reaction-diffusion system with nonlinear diffusion terms and the competitive Lotka-Volterra kinetics. The linear stability analysis shows that cross-diffusion,
