On continuum modeling of cell aggregation phenomena [PDF]
Journal of the Mechanics and Physics of Solids, 2022 Cellular aggregates play a significant role in the evolution of biological systems such as tumor growth, tissue spreading, wound healing, and biofilm formation. Analysis of such biological systems, in principle, includes examining the interplay of cell-cell interactions together with the cell-matrix interaction. These two interaction types mainly drive

Universality of filamentous aggregation phenomena [PDF]
Physical Review E, 2019 We use perturbative renormalization group theory to study the kinetics of protein aggregation phenomena in a unified manner across multiple timescales. Using this approach, we find that, irrespective of the specific molecular details or experimental conditions, filamentous assembly systems display universal behavior in time.

Effect of aggregation on adsorption phenomena [PDF]
The Journal of Chemical Physics, 2019 Adsorption at an attractive surface in a system with particles self-assembling into small clusters is studied by molecular dynamics simulation. We assume Lennard-Jones plus repulsive Yukawa tail interactions and focus on small densities. The relative increase in the temperature at the critical cluster concentration near the attractive surface (CCCS ...

Aggregation phenomena in lyotropic chromonic liquid crystals
Communications in Nonlinear Science and Numerical Simulation, 2023 We study the aggregation phenomenon in lyotropic chromonic liquid crystals as the molecular concentration changes and condensing agents are added into the system. Using properties of the critical points of the Oseen-Frank energy of a nematic liquid crystal, combined with the geometric constraints of the hexagonal columnar chromonic phases, we show that

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 ...

Scientific Reports, 2021 Formation of non-sessile, auto-aggregated cells of Staphylococcus aureus contributes to surface colonization and biofilm formation, hence play a major role in the early establishment of infection and in tolerance to antimicrobials.

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 ...

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 ...

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 ...
