Very often, when studying topological or dynamical properties of random scale-free networks, it is tacitly assumed that degree-degree correlations are not present. However, simple constraints, such as the absence of multiple edges and self-loops, can give rise to intrinsic correlations in these structures. In the same way that Fermionic correlations in thermodynamic systems are relevant only in...

A spillovers are a crucial factor in determining the optimal environment for innovation, there is no consensus regarding their impact on firm behavior. One reason for this may be that models differ in their assumptions for the functional form of the spillover pool. In industrial organization and economic geography, for example, the predominant convention is that all innovation within an industr...

We present a graphical analysis of the mechanisms underlying the occurrences of bubbling sequences and bistability regions in the bifurcation scenario of a special class of one dimensional two parameter maps. The main result of the analysis is that whether it is bubbling or bistability is decided by the sign of the third derivative at the inflection point of the map function.

It is shown that certain extremal correlators in four-dimensional N = 2 superconformal field theories (including N = 4 super-Yang-Mills as a special case) have a free-field functional form. It is further argued that the coupling constant dependence receives no correction beyond the lowest order. These results hold for any finite value of Nc. 1 UMR 5108 associée à l’Université de Savoie

2 PARAMETERIZED MODULES AS PARAMETERS A feature of OBJ3 not discussed in [8] allows the use of parameterized modules as parameter theories of other modules. The example below follows one suggested by Yatsu and Futatsugi [9] in connection with their design work on the CafeOBJ system [2]. The parameterized LIST object defines lists, with a comma syntax for concatenation. The theory FUN defines an...

We have proposed an adaptive procedure in order to estimate unknown parameters of a numerical model of a chaotic CO2 laser, which is observed through a time series that represents the output intensity of the laser. To do that, we consider a coupled system with the same functional form and adjustable parameters. The salient feature of the proposed technique is that accurate parameter estimation ...

Higher-Order Theories of Consciousness: An Anthology, edited by Rocco J. Gennaro, brings together fourteen new essays exploring the relative merits of and problems with higher-order representation (HOR) theories of consciousness. The anthology is divided into two parts. Part I contains articles by proponents of HOR theories arguing for their favorite version of the theory (Rosenthal, Gennaro, V...

Research has consistently demonstrated a negative and significant relationship between occupational feminization and wages. This has traditionally been attributed to societal mechanisms undervaluing the work mainly performed by women. More recently, empirical evidence from the US and Europe has supported theories based on the concept of specialized human capital. We examine whether lower wages ...
