Diffusion-Limited Aggregation on Curved Surfaces [PDF]
, 2010 We develop a general theory of transport-limited aggregation phenomena occurring on curved surfaces, based on stochastic iterated conformal maps and conformal projections to the complex plane. To illustrate the theory, we use stereographic projections to

Science Advances, 2023 Graphene quantum dots (GQDs) are nanosized graphene derivatives with unique photoluminescence (PL) properties that have advantages in optoelectronic applications due to their stable blue light emission. However, aggregation-caused quenching (ACQ) of GQDs

Dispersion state phase diagram of citrate-coated metallic nanoparticles in saline solutions
Nature Communications, 2020 Citrate-stabilized metallic colloids are key materials towards chemosensing and catalysis applications. Here the authors introduce a new theoretical model to estimate how the stoichiometry of citrate molecules absorbed onto spherical metallic ...

Aggregation bias and its drivers in large‐scale flood loss estimation: A Massachusetts case study
Journal of Flood Risk Management, 2022 Large‐scale estimations of flood losses are often based on spatially aggregated inputs. This makes risk assessments vulnerable to aggregation bias, a well‐studied, sometimes substantial outcome in analyses that model fine‐grained spatial phenomena at ...

Numerical validation of a population balance model describing cement paste rheology [PDF]
, 2020 Rheology control is essential during the period in which cement and concrete pastes are encountered in the fresh state, due to the fact that it directly affects workability, initial placement and the structural performance of the hardened material ...

Growing dynamics of Internet providers [PDF]
, 2001 In this paper we present a model for the growth and evolution of Internet providers. The model reproduces the data observed for the Internet connection as probed by tracing routes from different computers.

Social Aggregation as a Cooperative Game [PDF]
, 2010 A new approach for the description of phenomena of social aggregation is suggested. On the basis of psychological concepts (as for instance social norms and cultural coordinates), we deduce a general mechanism for the social aggregation in which ...

Aggregation pattern transitions by slightly varying the attractive/repulsive function. [PDF]
PLoS ONE, 2011 Among collective behaviors of biological swarms and flocks, the attractive/repulsive (A/R) functional links between particles play an important role. By slightly changing the cutoff distance of the A/R function, a drastic transition between two distinct ...
