Novel Features for Time Series Analysis: A Complex Networks Approach

Being able to capture the characteristics of a time series with a feature vector is a very important task with a multitude of applications, such as classification, clustering or forecasting. Usually, the features are obtained from linear and nonlinear time series measures, that may present several data related drawbacks. In this work we introduce NetF as an alternative set of features, incorporating several representative topological measures of different complex networks mappings of the time series. Our approach does not require data preprocessing and is applicable regardless of any data characteristics. Exploring our novel feature vector, we are able to connect mapped network features to properties inherent in diversified time series models, showing that NetF can be useful to characterize time data. Furthermore, we also demonstrate the applicability of our methodology in clustering synthetic and benchmark time series sets, comparing its performance with more conventional features, showcasing how NetF can achieve high-accuracy clusters. Our results are very promising, with network features from different mapping methods capturing different properties of the time series, adding a different and rich feature set to the literature

Multilayer Quantile Graph for Multivariate Time Series Analysis and Dimensionality Reduction

In recent years, there has been a surge in the prevalence of high- and multi-dimensional temporal data across various scientific disciplines. These datasets are characterized by their vast size and challenging potential for analysis. Such data typically exhibit serial and cross-dependency and possess high dimensionality, thereby introducing additional complexities to conventional time series analysis methods. To address these challenges, a recent and complementary approach has emerged, known as network-based analysis methods for multivariate time series. In univariate settings, Quantile Graphs have been employed to capture temporal transition properties and reduce data dimensionality by mapping observations to a smaller set of sample quantiles. To confront the increasingly prominent issue of high dimensionality, we propose an extension of Quantile Graphs into a multivariate variant, which we term "Multilayer Quantile Graphs". In this innovative mapping, each time series is transformed into a Quantile Graph, and inter-layer connections are established to link contemporaneous quantiles of pairwise series. This enables the analysis of dynamic transitions across multiple dimensions. In this study, we demonstrate the effectiveness of this new mapping using a synthetic multivariate time series dataset. We delve into the resulting network's topological structures, extract network features, and employ these features for original dataset analysis. Furthermore, we compare our results with a recent method from the literature. The resulting multilayer network offers a significant reduction in the dimensionality of the original data while capturing serial and cross-dimensional transitions. This approach facilitates the characterization and analysis of large multivariate time series datasets through network analysis techniques

UM OLHAR PARA A METODOLOGIA DA PRODUÇÃO TEXTUAL DE PROFESSORES DE LÍNGUA PORTUGUESA

O presente artigo buscou discutir as diferentes metodologias adotadas por quatro professoras de Língua Portuguesa para a produção textual em sala de aula. Foram considerados alguns referenciais para a produção deste trabalho, como os documentos oficiais – Base Nacional Comum Curricular e Parâmetros Curriculares Nacionais-, os quais colocam o texto como centro de uma aula de Língua Portuguesa. A pesquisa ainda contou com autores como Koch e Elias (2009), Emília Ferreiro (1997), Sírio Possenti (1996), Luiz Antônio Marcuschi (2008), João Wanderley Geraldi (1984/1986), entre outros.  As principais discussões do referencial teórico embasaram-se na história da língua portuguesa no Brasil, na produção textual em sala de aula e, por último, na metodologia e nos possíveis processos de ensino aprendizagem para produção textual. A partir de entrevistas realizadas com professoras de Língua Portuguesa de rede municipal e privada de Criciúma, buscou-se coletar como se dá a prática efetiva da produção em sala de aula, bem como a importância que elas dão para tal prática no ambiente escolar. Com base na análise, concluiu-se que as docentes sempre estão em busca de tornar a aula de Língua Portuguesa mais dinâmica, de modo que venha ao encontro daquilo que os documentos oficiais orientam e que permita aos alunos aprender com maior facilidade, o que contribui para a importância de se buscar novas formas para que a produção textual seja trabalhada em sala de aula, de maneira que instigue o estudante a querer ter o aprendizado por meio do texto

Motor activities to improve maths performance in pre-school children with typical development

Poor maths skills are associated with negative outcomes throughout life, such as lower academic qualifications, decreased professional success and socio-economic results. Mathematical skills emerge continuously throughout childhood and those that children acquire in pre-school are crucial for activities that support analytical thinking, problem-solving and reasoning and argumentation skills. Many of these activities are related to motor skills, since certain cognitive and motor areas of the brain are activated simultaneously when solving maths problems. Of all motor skills, visuomotor integration skills have been documented as those that are most consistently positively and significantly associated with maths performance in pre-school children. These skills are influenced by visual perception (spatial and attention skills), fine motor coordination and gross motor skills. Early intervention can improve visuomotor integration skills in pre-school children. Of all skills that make up visuomotor integration, spatial skills, in addition to being the first skills to influence numerical knowledge and the recognition of geometric shapes, are also those skills that form part of the majority of programs and activities to be worked on with pre-school children for the development of mathematical concepts. However, most intervention programs or activities to develop spatial skills are carried out in the classroom, usually through activities involving handling small objects. In this sense and given the significant association between visuomotor integration skills and gross motor skills, the main objective of this study was to list a set of activities to develop spatial skills, with a strong involvement of gross motor skills, in a classroom, playground or home context

Anticancer activity of rutin and its combination with ionic liquids on renal cells

The renal cell carcinoma (RCC) is the most common type of kidney cancer. Identifying novel and more effective therapies, while minimizing toxicity, continues to be fundamental in curtailing RCC. Rutin, a bioflavonoid widely found in nature, has shown promising anticancer properties, but with limited applicability due to its poor water solubility and pharmacokinetics. Thus, the potential anticancer effects of rutin toward a human renal cancer cell line (786-O), while considering its safety in Vero kidney cells, was assessed, as well as the applicability of ionic liquids (ILs) to improve drug delivery. Rutin (up to 50 µM) did not show relevant cytotoxic effects in Vero cells. However, in 786-O cells, a significant decrease in cell viability was already observed at 50 µM. Moreover, exposure to rutin caused a significant increase in the sub-G1 population of 786-O cells, reinforcing the possible anticancer activity of this biomolecule. Two choline-amino acid ILs, at non-toxic concentrations, enhanced rutin's solubility/loading while allowing the maintenance of rutin's anticancer effects. Globally, our findings suggest that rutin may have a beneficial impact against RCC and that its combination with ILs ensures that this poorly soluble drug is successfully incorporated into ILs-nanoparticles hybrid systems, allowing controlled drug delivery.Fundação para a Ciência e Tecnologia (FCT, Portugal): UID/DTP/04567/2019/ UIDB/00100/2020/ UIDB/04565/2020.

Residual and technical tax efficiency scores for Brazilian municipalities: a two-stage approach

Recurrent fiscal imbalances in terms of tax and expenditure assignments among central and local governments are a critical issue in public finance. To equalize tax capacities, cope with spillovers or to achieve national policy objectives, central governments often provide transfers to lower levels of government. These transfers may affect the incentives to improve fiscal performance because they may induce low tax effort in the regions (Litvack, Ahmad and Bird, 1998; Boadway et al., 1999).Recurrent fiscal imbalances in terms of tax and expenditure assignments among central and local governments are a critical issue in public finance.
