Multi-alphabetic hypercubes
Francisco, Carla; Mexia, João T.; Oliveira, Manuela; Carvalho, FranciscoThese hypercubes generalize the well-known Graeco-Latin squares. In one dimension m hypercube we have pm 'points' with m coordinates taking the values 0; 1; : : : ; p 1. In each point we locate letters from m distinct alphabets. When we vary one of the coordinates, we get all the letters of each of the alphabets. We show, how to use vector spaces over Galois Fields to obtain such hypercubes. Moreover, these hyp...
Chorionic villus sampling: 10 years of experience in a University referral center
Martins, Ana Teresa; Francisco, Carla; Correia, Hildeberto; Cohen, ÁlvaroObjectives: The purpose of this study was to estimate our center-specific CVS-related miscarriage rate. Methods: This is an observational retrospective study of women submitted to a CVS in our hospital, between January 1st, 2007 and December 31st, 2016. Maternal and pregnancy characteristics, procedure details, genetic results and pregnancy outcomes of all patients were collected. The FMF miscarriage risk algor...
Hadamard matrices on error detection and correction: useful links to BIBD
Francisco, Carla; Oliveira, Teresa A.; Oliveira, Amilcar; Carvalho, FranciscoIn the areas of Computer Science and Telecommunications there is a huge amount of applications in which error control, error detection and error correction are crucial tools to enable reliable delivery of digital data over unreliable communication, thus providing quality of service. Hadamard matrices can almost directly be used as an error-correcting code using an Hadamard code, generalized in Reed-Muller codes...
Hadamard matrices and links to information theory
Francisco, Carla; Oliveira, Amilcar; Grilo, Luis; Oliveira, Teresa A.The existence of Hadamard matrices remains one of the most challenging open questions in combinatorics. Substantial progress on their existence has resulted from advances in algebraic design theory using deep connections with linear algebra, abstract algebra, finite geometry, number theory, combinatorics and optimization. The construction and analysis of Hadamard matrices, and their use on combinatorial designs...
Using R in experimental design with BIBD: an application in health sciences
Francisco, Carla; Oliveira, Amilcar; Ferreira, Agostinho; Oliveira, Teresa A.Considering the implementation of an Experimental Design, in any field, the experimenter must pay particular attention and look for the best strategies in the following steps: planning the design selection, conduct the experiments, collect observed data, proceed to analysis and interpretation of results. The focus is on providing both - a deep understanding of the problem under research and a powerful experimen...
Delineamento experimental em blocos incompletos : estudo de casos particulares
Francisco, CarlaO Delineamento Experimental em Blocos Incompletos reveste-se de uma enorme importância uma vez que faz a ponte entre a matemática aplicada e as aplicações da estatística em áreas tão diversas como a agricultura, a medicina, a biometria, a criptografia, a genética, a indústria, as ciências da educação, entre muitas outras. Tem por objetivo principal a obtenção da maior quantidade de informação possível, a partir...
Resenha do romance Dois Rios, de Tatiana Salem Levy
Francisco, CarlaRecensão crítica ao romance Dois Rios de Tatiana Salem Levy, narrativa na qual a autora narrativa retoma, de uma forma diferente, a temática já abordada em A chave de casa: o retornar às origens, o enfrentar o passado e todos os fantasmas que este carrega consigo, bem como o encontrar-se com o outro para se reencontrar a si mesmo.
HANSEN DISEASE AND PREGNANCY
Lima, Ana Furtado; Francisco, Carla; Mendes, Neuza; Guerreiro, Cristina; Vieira, Raquel; Campos, AnaHansen disease, commonly called Leprosy, is an infectious disease caused by Mycobacterium leprae. In the past, the seriousness of the presentation of this disease associated with the inexistence of appropriate treatment, led to the stigmatization of these patients. Fortunately, the way we look now to Hansen disease has changed thanks to the existence of new antibacillary drugs. With migration phenomenon, we see...
Ovarian hyperstimulation syndrome in a spontaneous pregnancy.
Francisco, Carla; Júlio, Catarina; Pinto, Graça; Martins, Ana Teresa; Ferreira, Amadeu; Martins, LuísaOvarian hyperstimulation syndrome (OHSS) is considered to be an iatrogenic complication of ovulation induction therapy. However, OHSS may rarely be associated with spontaneous ovulatory cycles, usually in multiple or molar gestations or hypothyroidism. Clinical manifestations vary and may be potentially fatal in severe cases.A 28-year-old primigravid, with no history of an infertility treatment, presented with ...
