ii ABSTRACT Long dismissed as unscientific, teleological explanation has been undergoing something of a revival as a result of the emergence of self-organization theory, which combines micro-level dynamics with macro-level boundary conditions to explain the tendency of systems to develop toward stable end-states. On that methodological basis this article(More)
We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is a planet with a minimum mass M sin i of 5.36 ± 0.69 M ⊕ with an orbital period of 8.7076 ± 0.0025 days at a distance of 0.066610(13) AU, and an orbit that is consistent with(More)
This paper presents a method to recover the wavefront phase at the telescope pupil, distorted because of the atmosphere action, and its use to command a deformable mirror to compensate for the optical aberrations in real time (AOLI instrument). For this purpose, an evolution of the geometric sensor [1] was used to restore the wavefront from two defocused(More)
We examine the microscopic structure of a hard-sphere fluid confined to a small cylindrical pore by means of Monte Carlo simulation. In order to analyze finite-size effects, the simulations are carried out in the framework of different statistical mechanics ensembles. We find that the size effects are specially relevant in the canonical ensemble where(More)
We present a density functional theory for inhomogeneous fluids at constant external pressure. The theory is formulated for a volume-dependent density, n(r,V), defined as the conjugate variable of a generalized external potential, nu(r,V), that conveys the information on the pressure. An exact expression for the isothermal-isobaric free-energy density(More)
