Telescopic groups and symmetries of combinatorial maps

In the present paper, we show that many combinatorial and topological objects, such as maps, hypermaps, three-dimensional pavings, constellations and branched coverings of the two--sphere admit any given finite automorphism group. This enhances the already known results by Frucht, Cori -- Mach\`i, \v{S}ir\'{a}\v{n} -- \v{S}koviera, and other authors. We also provide a more universal technique for showing that ``any finite automorphism group is possible'', that is applicable to wider classes or, in contrast, to more particular sub-classes of said combinatorial and geometric objects. Finally, we show that any given finite automorphism group can be realised by sufficiently many non-isomorphic such entities (super-exponentially many with respect to a certain combinatorial complexity measure).Comment: 29 pages, 7 figures; final version to appear in Algebraic Combinatorics https://alco.centre-mersenne.or

Projeto de intervenção sobre o alcoolismo na área de abrangência da Equipe "Cidade de Deus I". Sete Lagoas - Minas Gerais

A Síndrome de Dependência do Álcool (SDA) é um grave problema de saúde pública. Ela é um transtorno psiquiátrico com severas repercussões individuais, sociais e econômicas de âmbito mundial. O seu quadro clínico é bastante estudado e conhecido e, embora seus critérios diagnósticos sejam claros e tenham sido estabelecidos há vários anos, os transtornos relacionados ao uso de álcool ainda constituem um drama para a saúde pública, tanto pela dificuldade de seu tratamento quanto pelo desafio que a identificação dos casos iniciais e, às vezes, até dos quadros mais avançados representam para os médicos. Este trabalho tem como objetivo elaborar um Projeto de Intervenção para diminuir a alta taxa de alcoolismo na área de abrangência da equipe "Cidade de Deus I", do Programa de Saúde da Família do município de Sete Lagoas, em Minas Gerais. Para elaboração deste trabalho identificamos as principais causas que provocam o surgimento da Síndrome de Dependência Alcoólica pretendemos corrigir, tratar e diminuir estas causas, consequentemente o número de pacientes que precisam de atenção nos serviços de saúde por este motivo vão ser reduzidos. Realizamos um levantamento de dados utilizando publicações nacionais, artigos científicos disponíveis na internet além de manuais do Ministério da Saúde. A equipe considerou importante entender a gênese do problema síndrome da dependência alcoólica a partir da identificação de suas causas e chegar assim a uma melhor intervenção dos serviços de saúde por uma equipe multiprofissional, centrado nas peculiaridades de cada indivíduo, voltado para a prevenção e promoção de saúde, abrangendo paciente, e o seu núcleo familiar. Conclui-se que a execução das ações do projeto de intervenção contribuirá para a melhoria da saúde da população, aumentando o número de abstenções e diminuindo o número de casos novos, problema que é muito frequente na sociedade moderna

The Neuroelectromagnetic Inverse Problem and the Zero Dipole Localization Error

A tomography of neural sources could be constructed from EEG/MEG recordings once the neuroelectromagnetic inverse problem (NIP) is solved. Unfortunately the NIP lacks a unique solution and therefore additional constraints are needed to achieve uniqueness. Researchers are then confronted with the dilemma of choosing one solution on the basis of the advantages publicized by their authors. This study aims to help researchers to better guide their choices by clarifying what is hidden behind inverse solutions oversold by their apparently optimal properties to localize single sources. Here, we introduce an inverse solution (ANA) attaining perfect localization of single sources to illustrate how spurious sources emerge and destroy the reconstruction of simultaneously active sources. Although ANA is probably the simplest and robust alternative for data generated by a single dominant source plus noise, the main contribution of this manuscript is to show that zero localization error of single sources is a trivial and largely uninformative property unable to predict the performance of an inverse solution in presence of simultaneously active sources. We recommend as the most logical strategy for solving the NIP the incorporation of sound additional a priori information about neural generators that supplements the information contained in the data

The social challenge of public traditional radio in the 21st century

El artículo pretende develar las funciones de la radio tradicional en pleno siglo XXI, que más allá de informar y entretener (como se ha establecido desde la corriente funcionalista), permite la reflexión colectiva y articula el vínculo social. Ni olvidado, ni desaparecido, por sus bajos costes de producción y alta penetración social, el medio radial analógico facilita el acceso a los desconectados de la galaxia Internet en tiempos de remediación. El estudio clasifica como descriptivo con carácter teórico y documental. En este sentido, se identifican y caracterizan los roles de la plataforma radial en la generación de mecanismos para la participación ciudadana, el acompañamiento en tiempos de crisis, su incidencia en la educación problematizadora, la defensa de la cultura y el servicio público (facilitación social), en tanto se convierte en recurso para comunicar el patrimonio cultural de las ciudades. El artículo incorpora además, el análisis y síntesis de contenido desde la perspectiva crítica latinoamericana, que pondera como principal objeto social de la radio: la construcción colectiva de la ciudadanía.The article aims to reveal the functions of traditional radio in the 21st century, which, beyond informing and entertaining (as has been established for the functionalist current), allows collective reflection and articulates the social bond. Neither forgotten nor disappeared, due to its low production costs and high social penetration, has analogical radio facilitated access to the disconnected people from the Internet galaxy in times of remediation. The study is classified as descriptive with a theoretical and documentary nature. In this sense, the roles of the radio platform are identified and characterized in the generation of mechanisms for citizen participation, accompaniment at times of crisis, its incidence in problematizing education, the defense of culture and public service (social facilitation), in Therefore, it becomes a resource to communicate the cultural heritage of cities. The article also incorporates the analysis and synthesis of content from the Latin American critical perspective, which considers the collective construction of citizenship as the main social object of the radio.Facultad de Periodismo y Comunicación Socia

Spatiotemporal scales and links between electrical neuroimaging modalities

Recordings of brain electrophysiological activity provide the most direct reflect of neural function. Information contained in these signals varies as a function of the spatial scale at which recordings are done: from single cell recording to large scale macroscopic fields, e.g., scalp EEG. Microscopic and macroscopic measurements and models in Neuroscience are often in conflict. Solving this conflict might require the developments of a sort of bio-statistical physics, a framework for relating the microscopic properties of individual cells to the macroscopic or bulk properties of neural circuits. Such a framework can only emerge in Neuroscience from the systematic analysis and modeling of the diverse recording scales from simultaneous measurements. In this article we briefly review the different measurement scales and models in modern neuroscience to try to identify the sources of conflict that might ultimately help to create a unified theory of brain electromagnetic fields. We argue that seen the different recording scales, from the single cell to the large scale fields measured by the scalp electroencephalogram, as derived from a unique physical magnitude—the electric potential that is measured in all cases—might help to conciliate microscopic and macroscopic models of neural function as well as the animal and human neuroscience literatur

ALTERNATIVA FÍSICA TERAPÉUTICA PARA LA REHABILITACIÓN DE LA CONDROMALACIA PATELAR GRADO 1

The pre-experimental study with Participation Action is aimed at the rehabilitation of chondromalacia femoro patellar in adolescents. To carry out the work, we start from an intentional sample consisting of four adolescents, made up of females and two males who attend the Calixto García de Holguín therapeutic area, with the purpose of elaborating a community physical therapeutic alternative. It was developed in four stages: diagnosis, elaboration, implementation and evaluation. In the elaboration, methods of the theoretical, empirical and mathematical-statistical level were used, as well as the use of diagnoses that allowed verifying that the entire sample presents chondromalacia femoro patellar grade 1, after the execution of the physical therapeutic alternative in the therapeutic area. Four adolescents undergoing treatment are rehabilitated. This alternative constitutes a contribution for professionals since it serves as a guide for improvement, based on a theoretical-methodological systematization.El estudio pre-experimental con Acción Participación va dirigido a la rehabilitación de la condromalacia femoro patelar en los adolecentes.

Bayesian Models of Mentalizing

Surprisingly effortless is the human capacity known as "mentalizing”, i.e., the ability to explain and predict the behavior of others by attributing to them independent mental states, such as beliefs, desires, emotions or intentions. This capacity is, among other factors, dependent on the correct anticipation of the dynamics of facially expressed emotions based on our beliefs and experience. Important information about the neural processes involved in mentalizing can be derived from dynamic recordings of neural activity such as the EEG. We here exemplify how the so-called Bayesian probabilistic models can help us to model the neural dynamic involved in the perception of clips that evolve from neutral to emotionally laden faces. Contrasting with conventional models, in Bayesian models, probabilities can be used to dynamically update beliefs based on new incoming information. Our results show that a reproducible model of the neural dynamic involved in the appraisal of facial expression can be derived from the grand mean ERP over five subjects. One of the two models used to predict the individual subject dynamic yield correct estimates for four of the five subjects analyzed. These results encourage the future use of Bayesian formalism to build more detailed models able to describe the single trial dynami
