Direct simulation of aggregation phenomena [PDF]
Communications in Mathematical Sciences, 2004 We present here an algorithm to simulate the motion of rigid bodies subject to a non–overlapping constraint, and which tend to aggregate when they get close to each other. The motion is induced by external forces. Two types of forces are considered here: drift force induced by the action of a surrounding fluid whose motion is prescribed, and stochastic

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 ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer. [PDF]
Mol OncolMutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

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 ...

Role of clay constituents in stone decay processes
Materiales de Construccion, 2001 Stone alterability/durability is depending upon a number of intrinsic and extrinsic factors among which "clay minerals" constituents, either diffused throughout the stone framework or as coating-filling of void spaces, can play an important role ...

The Influence of Shadow Effects on the Spectral Characteristics of Glacial Meltwater
Remote Sensing, 2020 The phenomenon of shadows due to glaciers is investigated in Antarctica. The observed shadow effect disrupts analyses conducted by remote sensing and is a challenge in the assessment of sediment meltwater plumes in polar marine environments.
