Real-parameter optimisation is a prolific research line with hundreds of publications per year. There exists an impressive number of alternatives in both algorithm families and enhancements over their respective original proposals. In this work, we analyse if this growth in the number of publications is correlated with a real progress in the field. We have selected five approaches from one of t...

To the Editor: Certain arthro-pod-borne epornitic flaviviruses, namely, West Nile virus (WNV) and Usutu virus (USUV), have spread recently in parts of Europe (1,2). In southern Spain, the emergence of a third virus of this type, known as Bagaza virus (BAGV), is of concern (3). Because of the outbreaks in 2010 in Cádiz (southern Spain) of WNV infection , which affected birds, horses, and humans,...

Despite efficient carbon monitoring system and the commercialization of battery technology for intra-port transportation, port management are found not adopting these environmental yet costly equipments. Port authority who regulates environmental policies lacks leverage to impose tangible reduction on emission through concession. This model integrates sustainability into port equipment expansio...

implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. these ports are best suited for patients requiring long-term therapy (>4 weeks). implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable adminis...

a digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. the system is designed in ka-band for a dvb-s2 satellite link. we use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. the six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. this approa...

Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending  on size and site of the port incision, type of the trocar that it is used, the condition of  the patient a...

[1] We have evaluated a regional-scale simulation of the Mediterranean outflow by comparison with field data obtained in the 1988 Gulf of Cádiz Expedition. Our ocean model is based upon the Hybrid Coordinate Ocean Model (HYCOM) and includes the Richardson number–dependent entrainment parameterization of Xu et al. (2006). Given realistic topography and sufficient resolution, the model reproduces...

We assessed the spatial variation in concentrations of ten metals faeces lesser black-backed gull (LBBG) Larus fuscus wintering at seven localities South-West Spain. found high faeces, with several elements (As, Cu, Mo, Pb, Zn) locally exceeding (by 2 to 11 times) derived Lowest Effect Level (LEL) values. also strong variation, related main pollution sources associated different sites. Faeces f...
