14 p, 663.8 KB On Poncelet's maps / Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mañosa Fernández, Víctor 1971- (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada III)
Given two ellipses, one surrounding the other one, Poncelet introduced a map P from the exterior one to itself by using the tangent lines to the interior ellipse. This procedure can be extended to any two smooth, nested and convex ovals and we call these types of maps, Poncelet's maps. [...]

Context. M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent picture of the link between the magnetic fields and underlying dynamo mechanisms, rotation, and activity. [...]

(Université de Liège. Complex and Entangled Systems from Atoms to Materials) ; Beschoten, Bernd (RWTH Aachen University)
We present time-resolved Kerr rotation measurements, showing spin lifetimes of over 100 ns at room temperature in monolayer MoSe. These long lifetimes are accompanied by an intriguing temperature-dependence of the Kerr amplitude, which increases with temperature up to 50 K and then abruptly switches sign. [...]

14 p, 253.9 KB On the set of periods of the 2-periodic Lyness' equation / Bastien, Guy (Université Pierre et Marie Curie) ; Mañosa Fernández, Víctor 1971- (Universitat Politècnica de Catalunya. Departament de Matemàtiques) ; Rogalski, Marc (Université des Sciences et Technologies de Lille)
We study the periodic solutions of the non-autonomous periodic Lyness' recurrence u = (a + u )/u, where {a} is a cycle with positive values a,b and with positive initial conditions. Among other methodological issues we give an outline of the proof of the following results: (1) If (a, b) ≠ (1, 1), then there exists a value p(a, b) such that for any p > p(a, b) there exist continua of initial conditions giving rise to 2p-periodic sequences.

Introducció. L'artroplàstia total de genoll (ATG) ha demostrat ser un procediment exitós i cost-efectiu en quant a la millora del dolor en pacients amb artrosi de genoll simptomàtica. No obstant això, entorn d'un 20% de pacients no està satisfet amb el resultat de la intervenció. [...]

94 p, 1.8 MB Variabilidad de diferentes tecnicas quirúrgicas al establecer la rotación de los componentes en la artroplastia total de rodilla y su correlación clínica / Yáñez Siller, Federico A. ; Hernández Hermoso, José Antonio, dir. ; Nescolarde Selva, Lexa Digna, dir. ; Pérez Andrés, Ricard, dir. ; Monllau García, Juan Carlos, dir.
L'adequada alineació rotacional dels components és una de les claus per a un bon resultat clínic i una adequada supervivència a llarg termini de la ATG (Berger, 1998; Bedard, 2011). S'han descrit diferents tècniques per analitzar l'alineació rotacional, gairebé totes elles utilitzant els talls axials en la tomografia axial computeritzada (TAC), tot i que no hi ha consens a prop de quina és la millor o més reproduïble (Van Houten, 2018).

Adequate rotational alignment of the components is one of the keys to a good clinical outcome and adequate long-term survival of TKA (Berger, 1998; Bedard, 2011). Different techniques have been described to analyze rotational alignment, almost all of them using axial slices in computerized axial tomography (CT), although there is no consensus about which is the best or most reproducible (Van Houten, 2018).
