Macroeconomic conditions and health in Britain : aggregation, dynamics and local area heterogeneity

Janke, Katharina; Lee, Kevin; Propper, Carol; Shields, … - 2020

We estimate a model that allows for dynamic and interdependent responses of morbidity in different local areas to economic conditions at the local and national level, with statistical selection of optimal local area. We apply this approach to quarterly British data on chronic health conditions...

Couples' time-use and aggregate labor market outcomes

Balleer, Almut; Merz, Monika; Papp, Tamás K. - 2021

We present a model of the time-allocation decision of spouses in order to study the role of heterogeneity in preferences and wages for couples' labor supply. Spouses differ in their tastes for market consumption and non-market goods and activities, and also in their offered or earned wages. They...

Entropy measures of cellular aggregation

Monti, D.; Ariano, P.; Distasi, C.; Zamburlin, P.; … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 13, pp. 2762-2770

In this paper a measure is proposed of the rate with which the collective motion of cells leads to aggregation and … structure formation. It will be shown that the spatial entropy of the cells tends to decrease during aggregation and an index … experiments on cellular migration and aggregation. …

Challenges and opportunities in complex materials: silica-reinforced elastomers

Schaefer, Dale W.; Suryawanshi, Chetan; Pakdel, Peyman; … - In: Physica A: Statistical Mechanics and its Applications 314 (2002) 1, pp. 686-695

Small-angle light and X-ray scattering are used to study the morphology of reinforcing fillers in organic rubbers. The data, which extend over six orders of magnitude in length scale, reveal a complex morphology of the powders consisting of primary particles, aggregates and agglomerates. The...

Shear-induced clustering in a simple driven diffusive model

O’Loan, O.J.; Evans, M.R.; Cates, M.E. - In: Physica A: Statistical Mechanics and its Applications 258 (1998) 1, pp. 109-122

We study a simple lattice model of shear-induced clustering in two dimensions in which clusters of particles aggregate under an imposed shear flow and fragment stochastically. Two non-equilibrium steady states are identified: an unjammed state and a jammed state characterised by a...

Cluster growth poised on the edge of break-up, II: From reaction kinetics to thermodynamics

Koponen, I.T. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 13, pp. 2659-2665

occurring growth processes, where one may expect that aggregation driven cluster growth is poised on the edge of cluster break …-up. We propose here a statistical thermodynamics description of such a growth process governed by size dependent aggregation …

Integrin clustering as a result of local membrane deformations and local signaling feedbacks

Felizzi, Federico; Iber, Dagmar - In: Physica A: Statistical Mechanics and its Applications 408 (2014) C, pp. 198-211

Integrins are essential receptors for the development and functioning of multicellular animals because they mediate cell adhesion and migration, and regulate cell proliferation and apoptosis. Ligand-dependent activation of integrins involves the formation of receptor clusters and this has been...
