Critical Influence of Water on the Polymorphism of 1,3-Dimethylurea and Other Heterogeneous Equilibria [PDF]
Molecules, 2023 It is shown that the presence of hundreds of ppm of water in 1,3-dimethylurea (DMU) powder led to the large depression of the transition temperature between the two enantiotropically related polymorphic forms of DMU (Form II → Form I) from 58 °C to 25 °C,

Dynamical selection of Nash equilibria using reinforcement learning: Emergence of heterogeneous mixed equilibria. [PDF]
PLoS ONE, 2018 We study the distribution of strategies in a large game that models how agents choose among different double auction markets. We classify the possible mean field Nash equilibria, which include potentially segregated states where an agent population can ...

Evolution of parasite transmission dispersion [PDF]
Royal Society Open ScienceAn open question in epidemiology is why transmission is often overdispersed, meaning that most new infections are driven by few infected individuals. For example, around 10% of COVID-19 cases cause 80% of new COVID-19 cases.

Dynamics of a Cournot game with bounded rational firms and various scale effects. [PDF]
PLoS ONEIn this paper, we focus on a dynamic Cournot game in the market with a nonlinear (isoelastic) demand function. In our model, there are N competing firms featured by nonlinear cost functions, which enhances our model's resemblance to real-world scenarios.

Protolytic equilibria in homogeneous and heterogeneous systems of ketoconazole and its direct spectrophotometric determination in tablets [PDF]
Journal of the Serbian Chemical Society, 2005 The acid-base equilibria of a diprotic, slightly hydrosoluble base ketoconazole were studied in homogeneous and heterogeneous water systems. The determinations were performed at 25ºC at a constant ionic strength of M(NaCl).

Existence and influence of mixed states in a model of vegetation patterns [PDF]
Nonlinear Processes in Geophysics, 2023 The Rietkerk vegetation model is a system of partial differential equations, which has been used to understand the formation and dynamics of spatial patterns in vegetation ecosystems, including desertification and biodiversity loss.

SCREENING IN SPACE: RICH AND POOR CONSUMERS IN A LINEAR CITY
Ural Mathematical Journal, 2021 Unlike standard models of monopolistic screening (second-degree price discrimination), we consider a situation where consumers are heterogeneous not only vertically, in their willingness to pay, but also horizontally, in their tastes or "addresses'' a la

Heterogeneous Equilibria with Deuterium [PDF]
Nature, 1937 THE heterogeneous equilibria between hydrogen and the metallic chlorides have been extensively studied, notably by Berger and Crut1 using a static method, and by Jellinek and his collaborators2 using a dynamic method. More recently, Kapustinsky3 has studied the reduction of cuprous chloride with both hydrogen and deuterium, using a static method.

A model of cycles and bubbles under heterogeneous beliefs in financial markets
Cogent Economics & Finance, 2023 I study the effect of heterogeneous beliefs about asset prices on the long-term behavior of financial markets. Starting from the ideas of Abreu and Brunnermeier (2003), a two-dimensional system of differential equations is developed.
