Irreducible complexity of iterated symmetric bimodal maps
We introduce a tree structure for the iterates of symmetric bimodal maps and
identify a subset which we prove to be isomorphic to the family of unimodal
maps. This subset is used as a second factor for a -product that we
define in the space of bimodal kneading sequences. Finally, we give some
properties for this product and study the *-product induced on the associated
Markov shifts
K-theory for Cuntz-Krieger algebras arising from real quadratic maps

Order and chaos: interactive computational activities for the classroom
It has long been believed that typical students learn better through contemporary approaches to questions originated by physics problems that allow experiments. This belief motivated us to develop interactive computational didactic materials about contemporaneous mathematics that can be used both in the classroom and in mathematics clubs in school. Dynamical Systems, the study of how physical systems evolve with time, inspired the activities developed. They share a key goal of understanding the order/chaos relationship in natural phenomena, human behaviour and social systems. Another goal to achieve is to give mathematics an experimental/laboratorial component, which rarely is present. In fact, all the interactive computational didactic materials developed include simulations and the capability to generate wonderful pictures, from which students can enjoy the beauty of mathematics.The first author was supported by the Centre of Research in Mathematics and Applications, University of Ăvora, through the FCT Pluriannual Funding Program.

Conference scene : Golden Helix Pharmacogenomics Days : educational activities on pharmacogenomics and personalized medicine
The Golden Helix Pharmacogenomics Days are high-profile international educational scientific meetings discussing pharmacogenomics and personalized medicine. Here, we provide an overview of the scientific lectures and the topics discussed during the 4th Golden Helix Pharmacogenomics Day, held in Cagliari, Italy, on 7 October 2011, and the 5th Golden Helix Pharmacogenomics Day, that was held in Msida, Malta, on 3 December 2011. The scientific programs of both events included scientific and company lectures on pharmacogenomics, bioinformatics and personalized medicine by local and international speakers from Europe and the USA.peer-reviewe

International Student Mobility: An Identity Development Task?
Based on the review of literature on internationalization of education and on identity formation pro

A jazida da Idade do bronze final da Tapada da Ajuda
Em Julho de 1982 foi localizada, no perĂmetro da Tapada da Ajuda, uma estação prĂ©-histĂłrica, na sequĂȘncia da abertura de extenso talude de escavação executado no Ăąmbito da construção de um complexo desportivo da Associação de Estudantes do Instituto Superior de Agronomia. Face ao interesse da jazida, dela se deu imediato conhecimento ao Conselho Directivo daquele Instituto, bem como ao Departamento de Arqueologia do Instituto PortuguĂȘs do PatrimĂłnio Cultural (IPPC). Ao mesmo tempo, promoveu-se a recolha de material Ă superfĂcie e no corte exposto, em que se baseou o estudo preliminar da jazida. No seguimento deste primeiro trabalho, continuado pela anĂĄlise dos materiais entretanto recolhidos por tĂ©cnicos do Departamento de Arqueologia do IPPC, a quem se agradece a sua cedĂȘncia para estudo, realizaram-se duas campanhas de escavação, em 1983 e 1984, em cujos resultados se baseia este trabalho.info:eu-repo/semantics/publishedVersio
Basins of attraction for a quadratic coquaternionic map
In this paper we consider the extension, to the algebra of coquaternions, of a complex quadratic map with a real super-attractive 8-cycle. We establish that, in addition to the real cycle, this new map has sets of non-isolated periodic points of period 8, forming four attractive 8-cycles. Here , the cycles are to be interpreted as cycles of sets and an appropriate notion of attractivity is used. Some characteristics of the basins of attraction of the five attracting 8-cycles are discussed and plots revealing the intertwined nature of these basins are shown.Research at CMAT was financed by Portuguese Funds through FCT - FundažcËao para a CiËencia e a Tecnologia, within the Project

Quaternionic polynomials with multiple zeros: A numerical point of view
In the ring of quaternionic polynomials there is no easy solution to the problem of finding a suitable definition of multiplicity of a zero.
In this paper we discuss different notions of multiple zeros available in the literature and add a computational point of view to this problem, by taking into account the behavior of the well known Newton's method in the presence of such roots.COMPETE reference number POCI-01-0145-FEDER-006683; FCT/MEC's financial support through national funding and by the ERDF through the Operational Programme on ``Competitiveness and Internationalization -- COMPETE 2020" under the PT2020 Partnership Agreementinfo:eu-repo/semantics/publishedVersio
