Excessive use of the preferred foot in on-the-ball skills execution compromises performance and tactical behaviour of football players

This study aimed to compare tactical behaviour and performance of football players with different on-theball skills execution functional technical asymmetry levels and to verify whether functional technical and tactical performance indexes of football players are associated. The sample included 59 football players (14.2 ± 1.5 years of age). FUT-SAT and SAFALL-FOOT were used as instruments for performance analysis. Participants were divided in two groups: higher and lower functional technical asymmetry. Student’s t-test was used to compare the behaviour and tactical performance of the groups, and the Pearson test was used to verify associations between functional technical asymmetry and tactical performance indexes. A significance level of 5% was adopted. The higher functional technical asymmetry group showed less tactical efficiency (t57 = 1.9; p = .05; d = .17) and low performance results in the execution of defensive actions (t57 = 2.1; p = .04; d = .55; t57 = 2.1; p = .04; d = .61) compared to the lower functional technical asymmetry group. No association was found between the functional technical asymmetry and tactical performance indexes (r = -.06; p = .66). It is concluded that the levels of functional technical asymmetry affected the behaviour and tactical performance of players although functional technical asymmetry and tactical performance indexes values are not associated. Future investigations may verify how football players with high and low levels of functional technical asymmetry change their behaviour and tactical performance from different kinds of training

Real Roots of Random Polynomials and Zero Crossing Properties of Diffusion Equation

We study various statistical properties of real roots of three different classes of random polynomials which recently attracted a vivid interest in the context of probability theory and quantum chaos. We first focus on gap probabilities on the real axis, i.e. the probability that these polynomials have no real root in a given interval. For generalized Kac polynomials, indexed by an integer d, of large degree n, one finds that the probability of no real root in the interval [0,1] decays as a power law n^{-\theta(d)} where \theta(d) > 0 is the persistence exponent of the diffusion equation with random initial conditions in spatial dimension d. For n \gg 1 even, the probability that they have no real root on the full real axis decays like n^{-2(\theta(2)+\theta(d))}. For Weyl polynomials and Binomial polynomials, this probability decays respectively like \exp{(-2\theta_{\infty}} \sqrt{n}) and \exp{(-\pi \theta_{\infty} \sqrt{n})} where \theta_{\infty} is such that \theta(d) = 2^{-3/2} \theta_{\infty} \sqrt{d} in large dimension d. We also show that the probability that such polynomials have exactly k roots on a given interval [a,b] has a scaling form given by \exp{(-N_{ab} \tilde \phi(k/N_{ab}))} where N_{ab} is the mean number of real roots in [a,b] and \tilde \phi(x) a universal scaling function. We develop a simple Mean Field (MF) theory reproducing qualitatively these scaling behaviors, and improve systematically this MF approach using the method of persistence with partial survival, which in some cases yields exact results. Finally, we show that the probability density function of the largest absolute value of the real roots has a universal algebraic tail with exponent {-2}. These analytical results are confirmed by detailed numerical computations.Comment: 32 pages, 16 figure

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Contracepção hormonal e lesões cervicais pelo Papilomavírus Humano: uma revisão de literatura / Hormonal contraception and cervical injuries by Human Papillomavirus: a literature review

Introdução: A infecção pelo papilomavírus humano (HPV) é a doença sexualmente transmissível (DST) mais comum, afetando 50% da população mundial. Estima-se que entre 75 e 80% da de indivíduos sexualmente ativos adquirirão algum subtipo de HPV ao longo da vida. No Brasil, a taxa de prevalência de HPV varia de 13,7 a 54,3%, de acordo com a população e as regiões estudadas. Assim, este artigo tem como objetivo analisar a associação entre os hormônios contracepção e o aparecimento de lesões induzidas por HPV em o colo uterino. Metodologia: O presente estudo foi elaborado por meio de uma pesquisa bibliográfica, realizada eletronicamente, procurando registros sobre o desenvolvimento de lesões induzidas por HPV em colo uterino e hormônios de contracepção. Objetivando com isso identificar através da literatura a associação entre os hormônios de contracepção e o aparecimento de lesões induzidas por HPV em colo uterino. Para a realização do mesmo foram analisados artigos publicados em revistas científicas, utilizando as bases de dados da BVS (Biblioteca Virtual da Saúde), como: Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Scielo (Scientific Electronic Library Online). Resultados: Após a seleção, restaram nove artigos para a discussão. Podemos observar os artigos escolhidos no quadro, composto pelos autores, título, metodologia, resultados e conclusão que cada um encontrou. Em seguida foi realizada uma discussão acerca destes artigos. Conclusão: Muitos estudos relataram que os mecanismos envolvidos na persistência e incidência de lesões de HPV estão longe de ser esclarecidas, e que novas estudos são necessários para elucidar melhores abordagens em relação ao tipo de contracepção, via de administração e doses hormonal que não estão associadas a lesões induzidas por HPV
