RoboCup Soccer Leagues

RoboCup was created in 1996 by a group of Japanese, American, and European Artificial Intelligence and Robotics researchers with a formidable, visionary long-term challenge: “By 2050 a team of robot soccer players will beat the human World Cup champion team.” At that time, in the mid 90s, when there were very few effective mobile robots and the Honda P2 humanoid robot was presented to a stunning public for the first time also in 1996, the RoboCup challenge, set as an adversarial game between teams of autonomous robots, was fascinating and exciting. RoboCup enthusiastically and concretely introduced three robot soccer leagues, namely “Simulation,” “Small-Size,” and “Middle-Size,” as we explain below, and organized its first competitions at IJCAI’97 in Nagoya with a surprising number of 100 participants [RC97]. It was the beginning of what became a continously growing research community. RoboCup established itself as a structured organization (the RoboCup Federation www.RoboCup.org). RoboCup fosters annual competition events, where the scientific challenges faced by the researchers are addressed in a setting that is attractive also to the general public. and the RoboCup events are the ones most popular and attended in the research fields of AI and Robotics.RoboCup further includes a technical symposium with contributions relevant to the RoboCup competitions and beyond to the general AI and robotics.

Automatic visual detection of human behavior: a review from 2000 to 2014

Due to advances in information technology (e.g., digital video cameras, ubiquitous sensors), the automatic detection of human behaviors from video is a very recent research topic. In this paper, we perform a systematic and recent literature review on this topic, from 2000 to 2014, covering a selection of 193 papers that were searched from six major scientific publishers. The selected papers were classified into three main subjects: detection techniques, datasets and applications. The detection techniques were divided into four categories (initialization, tracking, pose estimation and recognition). The list of datasets includes eight examples (e.g., Hollywood action). Finally, several application areas were identified, including human detection, abnormal activity detection, action recognition, player modeling and pedestrian detection. Our analysis provides a road map to guide future research for designing automatic visual human behavior detection systems.

O relatório que se apresenta respeita aos trabalhos arqueológicos desenvolvidos entre 2013 e 2014, inscritos no Projeto de Investigação Plurianual de Arqueologia (adiante PIPA) “Povoamento e Paisagens no Vale Superior do Rio Terva, Boticas – PoPaTERVA 2013-2016”, oportunamente aprovado pela Direção Geral do Património Cultural (DGPC: ofício n.º 2013/1 (169) CS: 875795 informação n.º 1704/DBC/2013). O projeto Povoamento e Paisagens no Vale Superior do Rio Terva, Boticas/ PoPaTERVA surge na sequência da conclusão do projeto de Conservação, Estudo, Valorização e Divulgação do Complexo Mineiro Antigo do Vale Superior do Rio Terva, Boticas, concebido em 2006 pela UAUM e executado entre 2010 e 2012 no âmbito de protocolo estabelecido com a Câmara Municipal de Boticas. Desta primeira ação de investigação resultou a classificação do Complexo Mineiro Antigo do Vale Superior do Rio Terva como Sítio de Interesse Público, promulgado pela Portaria n.º 386/2013 (DR, 2.º Série, n.º 115 de 18 de Junho de 2013 – ver Apêndice 7.1.2).

Povoamento e paisagens no Vale Superior do Rio Terva, Boticas: projecto de investigação plurianual em arqueologia (PoPaTERVA 2013-2016): trabalhos arqueológicos no Castro de Sapelos: relatório 2014

O presente relatório enquadra-se na execução do Projeto PoPaTERVA 2013-2016, um projeto PIPA aprovado pela DGPC em 2013 (oficio nº 06922, de 04-07-13. Ref. 2013/1 (169) CS 875795). Para o corrente ano de 2014 pretendemos dar continuidade às investigações decorrentes da implementação do projeto referido anteriormente, iniciando assim o estudo em pormenor do Castro de Sapelos. Os trabalhos arqueológicos foram iniciados a 1 de Julho e terminaram no mês de Dezembro, contaram com a participação de 4 jovens voluntários do programa municipal Boticas Mexe.

Targeting lactate transport suppresses in vivo breast tumour growth.

BACKGROUND Most cancers, including breast cancer, have high rates of glucose consumption, associated with lactate production, a process referred as "Warburg effect". Acidification of the tumour microenvironment by lactate extrusion, performed by lactate transporters (MCTs), is associated with higher cell proliferation, migration, invasion, angiogenesis and increased cell survival. Previously, we have described MCT1 up-regulation in breast carcinoma samples and demonstrated the importance of in vitro MCT inhibition. In this study, we performed siRNA knockdown of MCT1 and MCT4 in basal-like breast cancer cells in both normoxia and hypoxia conditions to validate the potential of lactate transport inhibition in breast cancer treatment. RESULTS The effect of MCT knockdown was evaluated on lactate efflux, proliferation, cell biomass, migration and invasion and induction of tumour xenografts in nude mice. MCT knockdown led to a decrease in in vitro tumour cell aggressiveness, with decreased lactate transport, cell proliferation, migration and invasion and, importantly, to an inhibition of in vivo tumour formation and growth. CONCLUSIONS This work supports MCTs as promising targets in cancer therapy, demonstrates the contribution of MCTs to cancer cell aggressiveness and, more importantly, shows, for the first time, the disruption of in vivo breast tumour growth by targeting lactate transport.

SMYD3 contributes to a more aggressive phenotype of prostate cancer and targets Cyclin D2 through H4K20me3

Prostate cancer (PCa) is one of the most incident cancers worldwide but clinical and pathological parameters have limited ability to discriminate between clinically significant and indolent PCa. Altered expression of histone methyltransferases and histone methylation patterns are involved in prostate carcinogenesis. SMYD3 transcript levels have prognostic value and discriminate among PCa with different clinical aggressiveness, so we decided to investigate its putative oncogenic role on PCa.We silenced SMYD3 and assess its impact through in vitro (cell viability, cell cycle, apoptosis, migration, invasion assays) and in vivo (tumor formation, angiogenesis). We evaluated SET domain's impact in PCa cells' phenotype. Histone marks deposition on SMYD3 putative target genes was assessed by ChIP analysis.Knockdown of SMYD3 attenuated malignant phenotype of LNCaP and PC3 cell lines. Deletions affecting the SET domain showed phenotypic impact similar to SMYD3 silencing, suggesting that tumorigenic effect is mediated through its histone methyltransferase activity. Moreover, CCND2 was identified as a putative target gene for SMYD3 transcriptional regulation, through trimethylation of H4K20.Our results support a proto-oncogenic role for SMYD3 in prostate carcinogenesis, mainly due to its methyltransferase enzymatic activity. Thus, SMYD3 overexpression is a potential biomarker for clinically aggressive disease and an attractive therapeutic target in PCa.

Índice Digital Regional 2014

O objetivo subjacente a toda a investigação que deu origem ao Índice Digital Regional (IDR), inserida num projeto de doutoramento, ia no sentido da “compreensão da realidade da Sociedade da Informação nas sete regiões NUTs II portuguesas, comparando-as e contrastando-as”. À semelhança do que acontece em grande parte dos indicadores de desenvolvimento, em que as assimetrias regionais são uma evidência verificada há várias décadas, importava perceber até que ponto o desenvolvimento da Sociedade da Informação em Portugal está a ser desencadeado sem ter ou não em atenção os valores da equidade, da coesão nacional e da solidariedade regional. Este artigo analisa os resultados do IDR recalculado com os dados estatísticos mais recentes.
