The Atomic-Level Structure of Cementitious Calcium Aluminate Silicate Hydrate

David Lyndon Emsley, Karen Scrivener, Paul Bowen, Pierrick Berruyer, Brennan James Walder, Pinelopi Moutzouri, Aslam Kunhi Mohamed, Jirawan Siramanont, Maya Nicole Harris, Mattia Negroni

Despite use of blended cements containing significant amounts of aluminum for over 30 years, the structural nature of aluminum in the main hydration product, calcium aluminate silicate hydrate (C-A-S-H), remains elusive. Using first-principles calculations ...

Learning Nash Equilibria in Monotone Games

Maryam Kamgarpour

We consider multi-agent decision making where each agent's cost function depends on all agents' strategies. We propose a distributed algorithm to learn a Nash equilibrium, whereby each agent uses only obtained values of her cost function at each joint play ...

The diversity of moral preferences: Evolutionary foundations and some implications in environmental economics

Boris Thurm

Empirical evidence suggests that there exists substantial heterogeneity in individuals' social preferences. However, there is little theoretical basis supporting this observation and economic models often assume that all individuals are identical. Hence, t ...

Noise-induced desynchronization and stochastic escape from equilibrium in complex networks

Robin Delabays

Complex physical systems are unavoidably subjected to external environments not accounted for in the set of differential equations that models them. The resulting perturbations are standardly represented by noise terms. If these terms are large enough, the ...

A disaggregate choice-based approach to find epsilon-equilibria of oligopolistic markets

Michel Bierlaire, Virginie Janine Camille Lurkin, Stefano Bortolomiol

We present a general framework to find epsilon-equilibrium solutions of oligopolistic markets in which demand is modeled at the disaggregate level using discrete choice models. Consumer choices are modeled according to random utility theory, and the choice ...

Quantifying Commitment in Nash Equilibria

Thomas Alois Weber

To quantify a player's commitment in a given Nash equilibrium of a finite dynamic game, we map the corresponding normal-form game to a "canonical extension," which allows each player to adjust his or her move with a certain probability. The commitment meas ...

Walrasian Dynamics in Multi-unit Markets

Aris Filos Ratsikas

In a multi-unit market, a seller brings multiple units of a good and tries to sell them to a set of buyers that have monetary endowments. While a Walrasian equilibrium does not always exist in this model, natural relaxations of the concept that retain its ...

Nash and Wardrop Equilibria in Aggregative Games With Coupling Constraints

Maryam Kamgarpour, John Lygeros

We consider the framework of aggregative games, in which the cost function of each agent depends on his own strategy and on the average population strategy. As first contribution, we investigate the relations between the concepts of Nash and Wardrop equili ...

Compound micromachines powered by acoustic streaming

Mahmut Selman Sakar, Furkan Ayhan, Murat Kaynak

This paper presents the design, fabrication, and operation of compound micromachines powered by acoustic streaming. The machine components were directly incorporated around pillars serving as shafts without further assembly steps using a single-step in sit ...
