Collusive networks in market sharing agreements in the presence of an antitrust authority

This paper studies how the presence of an antitrust authority affects market-sharing agreements made by firms in oligopolistic markets. These agreements prevent firms from entering each other´s market. The set of market-sharing agreements defines a collusive network, which is under suspicion by antitrust authorities. This paper shows that, from the firm´s point of view, the probability of being caught is endogenous and depends on the agreements each firm has signed. Stable collusive networks can be decomposed into a set of isolated firms and complete alliances of different sizes. While in the absence of the antitrust authority, a network is stable if its alliances are large enough, when the antitrust authority is considered, the network is stability depends on the network configuration as a whole. Antitrust laws may have a pro-competitive effect as they give Firms in large alliances more incentives to cut their agreements at once

Spin-Orbit mediated spin relaxation in monolayer MoS2

We study the intra-valley spin-orbit mediated spin relaxation in monolayers of MoS2 within a two bands effective Hamiltonian. The intrinsic spin splitting of the valence band as well as a Rashba-like coupling due to the breaking of the out-of-plane inversion symmetry are considered. We show that, in the hole doped regime, the out-of-plane spin relaxation is not very efficient since the spin splitting of the valence band tends to stabilize the spin polarization in this direction. We obtain spin lifetimes larger than nanoseconds, in agreement with recent valley polarization experiments.Comment: final version, 9 pages, 5 figure

Climate Responsive Design Simulation and Modelling for Industrial Heritage

The control of solar radiation is a basic dimension of modern design in all different types of constructions. Many architects have recently observed that different phases of sustainable design require a set of calculations and simulations that are necessary as a new standard design.'e valuable contributions to the process of sustainable design has a common denominator: solar radiation and comfort. In this way, motivated by all these new strategies and concepts, the large number of papers published suggests that the work has not been finished. 'is work provides an illustration of the Atarazanas regarding its climate responsiveness, focusing specifically on daylighting, shading, heat gain, and cooling loads. 'e objective is to assess the design of the Reales Atarazanas de Sevilla (Seville Royal Dockyards) to quantify how it is impacted by solar insolation and to provide insights about design characteristics that influence efficiency and conservation

Numerical model for material parameter identification of cells

Bacteria have a complex external layer that render them with an increased stiffness and more resistant to external invasion. The works aims to model the squeezing of a bacteria between two walls, and deduce the composition of bacterial external layer from the observed deformations. A FE based model will be developed for inferring the stiffness of baceria, solving an inverse problem from the applied loading and measured displacements. The results will be applied to laboraotry experiments carried out at Institu of Bioengineering of Catalunya (IBEC)
