ResumenA es un conjunto de Sidon en un grupo conmutativo G notado aditivamente si el número de representaciones de todo elemento no identidad de G como diferencia de dos elementos de A es a lo sumo 1. Una secuencia sonar m × n es una función f : {1, . . . , n} → {1, . . . , m} tal que su grafo asociado G f := {(x, f (x)) : 1 ≤ x ≤ n} es un conjunto de Sidon en el grupo Z × Z. Si G(m) denota el máximo entero positivo n tal que existe una secuencia sonar m × n, utilizando el concepto de energía aditiva y algunas de sus propiedades elementales. En este trabajo se prueba que G(m) ≤ m + 3,78m 2/3 + 4,76m 1/3 + 2. Además, utilizando la construcción de conjuntos de Sidon tipo Bose en Z q 2 −1 se construyen secuencias sonar (q − 1) × q, para toda potencia prima q.Palabras Clave: Conjuntos de Sidon, secuencias sonar, energía aditiva. AbstractA is a Sidon set in an additive commutative group G if the number of representations of each non-identity element in G, as a difference of two elements in A is at most 1. An m × n sonar sequence is a function f : {1, . . . , n} → {1, . . . , m} such that its associated graph G f := {(x, f (x)) : 1 ≤ x ≤ n} is a Sidon set in the group Z × Z. If G(m) denotes the maximum positive integer such that there exists an m × n sonar sequence, using additive energy and some of its properties. In this paper, we show that G(m) ≤ m + 3,78m2/3 + 4,76m 1/3 + 2. Furthermore, using the construction of Sidon sets type Bose in Z q 2 −1 we construct (q − 1) × q sonar sequences for all prime power q.

This is one of the first reports of a left subclavian pseudoaneurysm in a patient presenting with massive hemoptysis. We present a challenging case of a patient who consulted for hemoptysis. Imaging revealed a left subclavian artery pseudoaneurysm that caused a pulmonary parenchymal lesion. Treatment with a self-expanding thoracic stent-graft and a subclavian occluder was successful.

<p>The ongoing surge of international research on Asian Climate and Tectonics enables to better assess interactions between forcing mechanisms (global climate, India-Asia collision, Tibetan Plateau growth) and paleoenvironmental changes (monsoons, aridification), land-sea distribution, surface processes, paleobiogeographic evolution and the global carbon cycle. We review here the progress of the ERC MAGIC project (Monsoons in Asia caused Greenhouse to Icehouse Change?) integrating regional geodynamic constraints, well-dated environmental / biodiversity records and climate modeling. MAGIC focuses on the Paleogene period that includes the global Greenhouse to Icehouse cooling, the early collision and plateau growth and associated regional development of monsoons and westerlies over the Proto-Paratethys sea. Our work focuses on three areas constraining Asian paleoenvironments. (1) In Myanmar, paleomagnetic results, new dating of magmatic rocks and sediments along with additional detrital geochronology and basin analysis of the Burmese subduction margin and implications for the history of India-Asia convergence. (2) Along the Northeastern Tibetan Plateau margin, the combination of multiple proxies (leaf wax stable isotope, pollen, grain size, etc…)  applied to an extended lacustrine Paleogene record enables to identify precisely Asian climate changes and their consequences on ecosystems. (3) In westernmost China and Tajikistan, the proto-Paratethys sea fluctuations and the sedimentary records of Pamir tectonic evolution are now precisely dated enabling to constrain driving mechanisms and paleoenvironmental consequences. Together these results are used to constrain climate modeling experiments which permit validation of hypotheses on interactions between paleogeography, paleoenvironments and paleobiodiversity at Asian and global scales in response to long-term and short-term events.</p>
