Becker on Ewald on Foucault on Becker American Neoliberalism and Michel Foucault's 1979 'Birth of Biopolitics' Lectures

Abstract: In a series of lectures delivered in 1979 at the College de France under the title The Birth of Biopolitics, Michel Foucault conducted a close reading of Gary Becker’s writings on human capital and on crime and punishment, within the context of an elaboration and critique of American neoliberalism. Foucault was assisted at the time, at the College de France, by Francois Ewald. Since then, there has been ongoing debate over Foucault’s views about neoliberalism. In this historic meeting at the University of Chicago between Professors Becker and Ewald, Professor Ewald presents a framework to understand Foucault’s writings on Becker; Professor Bernard Harcourt offers a different reading of Foucault’s views on neoliberalism; and Professor Becker responds to Foucault’s lectures and to possible critical readings of his work on human capital. Apology or critique — that is the motivating question in this rich encounter between contemporary French philosophy and American economic theory.

An intrinsic Hamiltonian formulation of network dynamics: Non-standard Poisson structures and gyrators

Abstract: The aim of this paper is to provide an intrinsic Hamiltonian formulation of the equations of motion of network models of non-resistive physical systems. A recently developed extension of the classical Hamiltonian equations of motion considers systems with state space given by Poisson manifolds endowed with degenerate Poisson structures, examples of which naturally appear in the reduction of systems with symmetry. The link with network representations of non-resistive physical systems is established using the generalized bond graph formalism which has the essential feature of symmetrizing all the energetic network elements into a single class and introducing a coupling unit gyrator. The relation between the Hamiltonian formalism and network dynamics is then investigated through the representation of the invariants of the system, either captured in the degeneracy of the Poisson structure or in the topological constraints at the ports of the gyrative type network structure. This provides a Hamiltonian formulation of dimension equal to the order of the physical system, in particular, for odd dimensional systems. A striking example is the direct Hamiltonian formulation of electrical LC networks.

Calixarene‐Based Fluorescent Molecular Sensors for Toxic Metals

Abstract: There is an increasing interest in the early detection of toxic metals in the environment. In this context, fluorescence is a very attractive detection method because of its intrinsic sensitivity, its response time and the possibility of imaging via fluorescence microscopy. Of the various complexing units available for the detection of toxic metal ions (chelators, open-chain structures, crown-ethers, cryptands), calixarenes offer distinct advantages in term of selectivity and the easy incorporation of a fluorophore into the structure. In this microreview, after recalling the main classes offluorescent molecular sensors based on cation-induced changes in excited-state processes (photoinduced electron- or charge-transfer, excimer formation, energy transfer), we present various calixarene-based sensors designed for the detection of caesium, mercury, lead and cadmium.(© Wiley-VCH Verlag GmbH & Co.

Using a Mixed Integer Quadratic Programming Solver for the Unconstrained Quadratic 0-1 Problem

Abstract: In this paper, we consider problem (P) of minimizing a quadratic function q(x)=x tQx+ctx of binary variables. Our main idea is to use the recent Mixed Integer Quadratic Programming (MIQP) solvers. But, for this, we have to first convexify the objective function q(x). A classical trick is to raise up the diagonal entries of Q by a vector u until (Q+diag(u)) is positive semidefinite. Then, using the fact that xi2=xi, we can obtain an equivalent convex objective function, which can then be handled by an MIQP solver. Hence, computing a suitable vector u constitutes a preprocessing phase in this exact solution method. We devise two different preprocessing methods. The first one is straightforward and consists in computing the smallest eigenvalue of Q. In the second method, vector u is obtained once a classical SDP relaxation of (P) is solved.We carry out computational tests using the generator of (Pardalos and Rodgers, 1990) and we compare our two solution methods to several other exact solution methods. Furthermore, we report computational results for the max-cut problem.
