Abstract
Introduction. The study of the clinical workflows and information flows in healthcare institutions is of vital importance to improve its effectiveness and efficiency. At Hospital Sao Joao, Oporto Portugal, a Diagnostic Breast Unit (DBU) was recently created. The implementation of a new Electronic Patient Record (EPR) called Breast.Care triggered the need to better understand the DBU processes and suggest improvements. Aim. To describe clinical workflows and information flows in DBU, detect problems and propose solutions for better communication among different actors. Methods. The study started with a direct observation period with a total of 24 hours. The observed processes and flows were transcribed into free text and then into structured text, tables and Unified Modeling Language (UML) diagrams (activity and partition-activity). The structured text and diagrams were analysed to find possible improvements. Results. Seven main processes were identified representing how different actors (humans and computers) work together. Three communication process improvements between humans were detected (e.g. changing timing of patient data insertion to facilitate reading access to others), three human machine improvements (e.g. changing computer medical forms) and one between machines (creating specific links between information systems). Discussion. Analysing workflow and information flow in DBU allowed the detection of communication problems and the improvement of those through changes in EPR and in DBU current processes.

Abstract
Oncoplastic Breast Surgery (OPBS) is becoming an integral part of breast cancer management, but few surgeons have received formal training in these techniques. An International Symposium has recently debated the key issues which impact on training and specialisation in OPBS, as well as patient access to these procedures. The Symposium concluded that increasing the availability of OPBS is a major challenge, which demands much closer collaboration and cooperation between breast and plastic surgeons, backed up by new training schemes, new curricula and new guidelines.

Abstract
The inclusion of the presentation of music in a conference dealing with technical or cultural aspects of that same music has evolved significantly. An important aspect of music presentation is the opportunity it provides for public engagement. Conferences that have a music program often follow two different approaches, or a combination of these that includes the creation of a music committee inways similar to a scientific committee, or the invitation of curators to select the program for one or more concerts in the conference. Models of new music creation have significantly expanded to include close composer-performer collaboration which in some cases results in coauthorship. The conference-plus-festival format needs to be able to expand and refine the process of submitting a work for public presentation in order to adequately exhibit the variety of approaches to music production and dissemination.

Abstract
The eruption solitons that exist under the complex cubic-quintic Ginzburg-Landau equation (CGLE) may be eliminated by the introduction of a term that in the optical context represents intrapulse Raman scattering (IRS) The later was observed in direct numerical simulations and here we have obtained the system of ordinary differential equations and the corresponding traveling solitons that replace the eruption solutions In fact we have found traveling solutions for a subset of the eruption CGLE parameter region and a wide range of the IRS parameter However for each set of CGLE parameters they are stable solely above a certain threshold of IRS

Abstract
Ultrashort pulse propagation in fibers is affected by intrapulse Raman scattering (IRS) which causes both a linear frequency downshift and a quadratic displacement of the peak pulse, as functions of the propagation distance. This effect has been known and treated by perturbation methods applied to the nonlinear Schroumldinger equation since the period of intense research on soliton propagation. Here, we find solutions of the model equation using an accelerating self-similarity variable and study their stability. These solutions have Airy function asymptotics which give them infinite energy. For small IRS, the algebraically decaying tail is negligible and these solutions are a very good approximation of the profiles observed in the full equation simulations. For strong IRS (but beyond the regime in which the evolution equation is valid for silica fibers), the self-similar pulses have noticeable left tails exhibiting Airy oscillations. Whenever their truncated forms are used as initial conditions of the full equation, they experience amplitude decay and show left tails that are consistent with radiation escaping from the central pulse. These observations are interpreted as being the effects of a continuum constitution of the infinite left tail.

Abstract
New types of finite energy Airy beams are proposed. We consider two different types of beams, namely, beams that are obtained as blocked and exponentially attenuated versions of Airy functions Ai and Bi, and beams of finite width but having the Airy functions typical phase. All of them show very interesting properties, such as parabolic trajectories for longer propagation distances, profile evolution exhibiting less diffraction, or better definiteness of the main peak, when compared with other finite energy Airy beams studied before.
