Stability of Some Mechanisms of Chemotactic Aggregation

SIAM Journal on Applied Mathematics, 2002
The stability of a blow-up mechanism for a particular Keller-Segel model that yields chemotactic aggregation is investigated. It is shown using matched asymptotic methods that the considered blow-up mechanism is stable. It is shown that small perturbations of the initial data produce a small shifting on the blow-up time and the blow-up point but not ...

GLOBAL STABILITY OF NASH EQUILIBRIUM IN AGGREGATIVE GAMES [PDF]

International Game Theory Review, 2014
If an aggregative game satisfies the generalized Hahn conditions, then there exists a unique Nash equilibrium which may not be interior and is globally asymptotically stable under two alternative continuous adjustment processes with non-negativity constraints.

Gravity as a factor of aggregative stability and coagulation

Advances in Colloid and Interface Science, 2007
Gravity is a potential factor of aggregative stability and/or coagulation for any heterogeneous system having a density contrast between the dispersed phase and its dispersion medium. However, gravity becomes comparable to other stability factors only when the particle size becomes large enough.

Chemical and Physical Stability of Microbially Stabilized Aggregates

Soil Science Society of America Journal, 1971
Abstract Chemical properties of microbially bound aggregates were determined by organic solvent extraction and by the rate of sonic dispersion of the aggregates. Seven fungi, six streptomycetes, and four bacteria, produced in situ chemically different binding agents which ...

Protein stability and aggregation in Parkinson's disease

Biochemical Journal, 2008
Parkinson's disease (PD), the second most common age-related neurodegenerative disease, results in abnormalities in motor functioning. Many fundamental questions regarding its aetiology remain unanswered. Pathologically, it is not until 70–80% of the dopaminergic neurons from the substantia nigra pars compacta are lost before clinical symptoms are ...

Debt, Price Flexibility and Aggregate Stability [PDF]

, 1991
In conventional macroeconomic thought, price flexibility stabilizes thc economy. The more quickly prices fall (or inflation decreases) in a demand-induced recession, the faster output returns to its full-employment level. An alternative tradition, however, suggests that price flexibility can be destabilizing.

Aggregate Output Stability: Divergent Perspectives

Journal of Business and Economic Studies
The main objective of this article was to describe two asymmetric perspectives of the aggregate imbalance approach. Starting from the contrast of the Rational Expectations and Keynesian approaches, we analyze the characterization that the general reserve makes of the causes of inflation and the implications that it has on economic policy decisions ...

Polyacrylamide adsorption and aggregate stability

Soil and Tillage Research, 1999
Abstract The adsorption characteristics of synthetic organic polymers play a major role in their effects on the stabilization of aggregates. We hypothesized that high molecular weight polymers adsorb on both outer and inner surfaces of large aggregates (>1.0 mm), and thus enhance the resistance of aggregates to external forces (e.g., water drop ...

Aggregate Substitution Effects Implying Global Stability

Journal of Economic Theory, 2001
A system of autonomous differential equations is considered with the goal of using in economics. The author discusses the stability arguments for tatonnement. The basic aim here is to show that the standard conditions used to obtain global stability depend only on aggregate substitution effects.
