Efecto de la hiperuricemia en el endotelio y en la función renal de pacientes con trasplante renal

2019

La tesis “Efecto de la hiperuricemia en el endotelio y en la función renal de pacientes con trasplante renal” intenta aproximarse al papel del ácido úrico sérico como factor de disfunción endotelial e inflamación en una población de pacientes trasplantados renales. A lo largo de la historia de la medicina, al ácido úrico se ha postulado, por un lado, como una molécula con propiedades beneficiosas como factor evolutivo en el homo sapiens y, por otro lado, como molécula patogénica implicada en la fisiopatología de algunas enfermedades. Sin embargo, hasta el día de hoy, no existe una explicación plausible con la suficiente evidencia que justifique el papel causal del ácido úri…

Density flow over networks: A mean-field game theoretic approach

2014

A distributed routing control algorithm for dynamic networks has recently been presented in the literature. The networks were modeled using time evolution of density at network edges and the routing control algorithm allowed edge density to converge to a Wardrop equilibrium, which was characterized by an equal traffic density on all used paths. We borrow the idea and rearrange the density model to recast the problem within the framework of mean-field games. The contribution of this paper is three-fold. First, we provide a mean-field game formulation of the problem at hand. Second, we illustrate an extended state space solution approach. Third, we study the stochastic case where the density …

Distributed $n$-player approachability and consensus in coalitional games

2015

We study a distributed allocation process where, at each time, every player: i) proposes a new bid based on the average utilities produced up to that time, ii) adjusts such allocations based on the inputs received from its neighbors, and iii) generates and allocates new utilities. The average allocations evolve according to a doubly (over time and space) averaging algorithm. We study conditions under which the average allocations reach consensus to any point within a predefined target set even in the presence of adversarial disturbances. Motivations arise in the context of coalitional games with transferable utilities (TU) where the target set is any set of allocations that makes the grand …

Game Theory with Engineering Applications

2016

Engineering systems are highly distributed collective systems—decisions, information, and objectives are distributed throughout—that have humans in the loop, and thus decisions may be influenced by socioeconomic factors. Engineering systems emphasize the potential of control and games beyond traditional applications. Game theory can be used to design incentives to obtain socially desirable behaviors on the part of the players, for example, a change in the consumption patterns on the part of the “prosumers” (producers-consumers) or better redistribution of traffic. This unique book addresses the foundations of game theory, with an emphasis on the physical intuition behind the concepts, an an…

Labor Market Search, Housing Prices and Borrowing Constraints.

2010

Mortgage market deregulation in the early 1980s coincided in time with a sharp break in the cyclical behavior of many variables related to housing and to the labor market. This paper analyses the joint dynamics of labor market variables, output and housing prices in a search model with efficient bargaining and financial frictions. In a setting of household heterogeneity, only mortgaged-backed loans are available for impatient households, whose borrowing cannot exceed a proportion of the expected value of their real estate holdings. This feature of the credit market, together with search and matching frictions in the labor market, establish a strong link between credit constraints and consum…

Defining relations of minimal degree of the trace algebra of 3 X 3 matrices

2008

The trace algebra Cnd over a field of characteristic 0 is generated by all traces of products of d generic n × n matrices, n, d 2. Minimal sets of generators of Cnd are known for n = 2 and n = 3 for any d as well as for n = 4 and n = 5 and d = 2. The defining relations between the generators are found for n = 2 and any d and for n = 3, d = 2 only. Starting with the generating set of C3d given by Abeasis and Pittaluga in 1989, we have shown that the minimal degree of the set of defining relations of C3d is equal to 7 for any d 3. We have determined all relations of minimal degree. For d = 3 we have also found the defining relations of degree 8. The proofs are based on methods of representati…

Vasellame in vetro dalle cisterne del castello di Butera

2012

The assemblage of glass artefacts, which is the subject of this contribution, has been retrieved from four cisterns (A, B, C, F) of the Medieval Castle of Butera. They are closed contexts, which were not manipulated by modern interventions, and permit a better defnition of the chronology of the glass objects through their association with ceramic material
