Background
In 2007, a partnership was initiated between a small-volume paediatric cardiac surgery unit located in Las Palmas de Gran Canaria, Spain, and a large-volume cardiac surgery unit located in Milan, Italy. The main goal of this partnership was to provide surgical treatment to children with CHD in the Canary Islands.
MethodsAn operative algorithm for performing surgery in elective, urgent, and emergency cases was adopted by the this joint programme. Demographic and in-hospital variables were collected from the medical records of all the patients who had undergone surgical intervention for CHD from January, 2009 to March, 2013. Data were introduced into the congenital database of the European Congenital Heart Surgeons Association Congenital Database and the database was interrogated.
ResultsIn total, 65 surgical mission trips were performed during the period of this study. The European Congenital Heart Surgeons Association Congenital Database documented 214 total patients with a mean age at operation of 36.45 months, 316 procedures in total with 198 cardiopulmonary bypass cases, 46 non-cardiopulmonary bypass cases, 26 cardiovascular cases without cardiopulmonary bypass, 22 miscellaneous other types of cases, 16 interventional cardiology cases, six thoracic cases, one non-cardiac, non-thoracic procedure on a cardiac patient with cardiac anaesthesia, and one extracorporeal membrane oxygenation case. The 30-day mortality was 6.07% (13 patients).
ConclusionsA joint programme between a small-volume centre and a large-volume centre may represent a valid and reproducible model for safe paediatric cardiac surgery in the context of a peripheral region.

Summary
The short periodic orbit (PO) approach was developed in order to understand the structure of stationary states of quantum autonomous Hamiltonian systems corresponding to a classical chaotic Hamiltonian. In this chapter, we will describe the method for the case of a two-dimensional chaotic billiard where the Schrödinger equation reduces to the Helmholtz equation; then, it can directly be applied to evaluate the acoustic eigenfunctions of a two-dimensional cavity. This method consists of the short-wavelength construction of a basis of wavefunctions related to unstable short POs of the billiard, and the evaluation of matrix elements of the Laplacian in order to specify the eigenfunctions.
Introduction
The theoretical study of wave phenomena in systems with irregular motion received a big impetus after the works by Gutzwiller (summarized in Gutzwiller 1990). He derived a semiclassical approach providing the energy spectrum of a classically chaotic Hamiltonian system as a function of its POs. This formalism is very efficient for the evaluation of mean properties of eigenvalues and eigenfunctions (Berry 1985, Bogomolny 1988), but it suffers from a very serious limitation when a description of individual eigenfunctions is required: the number of used POs proliferates exponentially with the complexity of the eigenfunction. In this way, the approach loses two of the common advantages of asymptotic techniques: simplicity in the calculation and, more important, simplicity in the interpretation of the results.
Based on numerical experiments in the Bunimovich stadium billiard (Vergini & Wisniacki 1998), we have derived a short PO approach (Vergini 2000), which was successfully verified in the stadium billiard (Vergini & Carlo 2000): the first 25 eigenfunctions were computed by using five periodic orbits.

The Working Group FITS (WG-FITS) is the international control authority for the Flexible Image Transport System (FITS) data format. The WG-FITS was formed in 1988 by a formal resolution of the IAU XX General Assembly in Baltimore (MD, USA), 1988, to maintain the existing FITS standards and to approve future extensions to FITS.

The business meeting began with a brief review of the current rules and procedures of the WG, which are documented on the WG web page. Four regional FITS committees have been established by the WG, covering North American, Europe, Japan, and Australian/New Zealand, to provide advice to the WG on pending proposals. While it is recognized that this committee structure might need to be revised to provide representation to other regions, the current system is working well, and there were no motions to make any changes at this time.
