Smuggling, Betrayal, and the Handle of a Gun: Death, Laughter, and the Narcocorrido
No full textA comparison of two narcocorridos, Los Tigres del Norte’s “Contrabando y traición” (1974) and Alfredo Ríos’s “El Katch” (2009), highlights both continuity and change in core features of the genre. Whereas Los Tigres del Norte demonstrate a greater degree of restraint, a change of perspective enables Ríos to enthusiastically celebrate the illicit lifestyle of the narco-trafficker. The lighthearted musical setting of “El Katch” emphasizes personal autonomy by degrading the sense of the power of death, but a preoccupation with mortality remains, following Ríos beyond the song’s boundaries into his off-stage reality.Peer reviewedPublished online July 5, 2013, according to publisher's website

From Oklahoma! to Tick, Tick...Boom! The Evolution of the Musical from the Golden Age to Jonathan Larson’s Rock works
No full textEl musical cinematográfico no evoluciona de forma paralela a los musicales teatrales que se
llevan a los escenarios en Broadway. Esto genera un desfase de una década aproximadamente
entre los musicales que se estrenan en la Costa Este y los que llegan a Hollywood. En 2021,
Lin-Manuel Miranda dirige Tick, tick... Boom!, una obra con la que revive a Jonathan Lar-
son, heredero de las influencias del musical de Richard Rodgers y Oscar Hammerstein II,
y Stephen Sondheim.Musical films do not evolve in parallel with the theatrical musicals on Broadway. It creates a

On the complexity of the minimum domination problem restricted by forbidden induced subgraphs of small size
No full textWe study the computational complexity of the minimum dominating set problem on graphs restricted by forbidden induced subgraphs. We give some dichotomies results for the problem on graphs defined by any combination of forbidden induced subgraphs with at most four vertices, implying either an NP-Hardness proof or a polynomial time algorithm. We also extend the results by showing that dominating set problem remains NP-hard even when the graph has maximum degree three, it is planar and has no induced claw, induced diamond, induced K4 nor induced cycle of length 4, 5, 7, 8, 9, 10 and 11.Fil: Lin, Min Chih.

Efficient and Perfect domination on circular-arc graphs
No full textGiven a graph G = (V,E), a perfect dominating set is a subset of vertices V ⊆ V (G) such that each vertex v ∈ V (G) \ V is dominated by exactly one vertex v ∈ V . An efficient dominating set is a perfect dominating set V where V is also an independent set. These problems are usually posed in terms of edges instead of vertices. Both problems, either for the vertex or edge variant, remains NP-Hard, even when restricted to certain graphs families. We study both variants of the problems for the circular-arc graphs, and show efficient algorithms for all of them.Fil: Lin, Min Chih. Universidad de Buenos Aires.

6D SCFTs, center-flavor symmetries, and Stiefel-Whitney compactifications
No full textThe center-flavor symmetry of a gauge theory specifies the global form of consistent gauge and flavor bundle background field configurations. For 6D gauge theories which arise from a tensor branch deformation of a superconformal field theory (SCFT), we determine the global structure of such background field configurations, including possible continuous Abelian symmetry and R-symmetry bundles. Proceeding to the conformal fixed point, this provides a prescription for reading off the global form of the continuous factors of the zero-form symmetry, including possible nontrivial mixing between flavor and R-symmetry. As an application, we show that this global structure leads to a large class of 4D N=2 SCFTs obtained by compactifying on a T2 in the presence of a topologically nontrivial flat flavor bundle characterized by an ’t Hooft magnetic flux. The resulting “Stiefel-Whitney twisted” compactifications realize several new infinite families of 4D N=2 SCFTs, and also furnish a 6D origin for a number of recently discovered rank one and two 4D N=2 SCFTs.The center-flavor symmetry of a gauge theory specifies the global form of consistent gauge and flavor bundle background field configurations.

Functionalised DNA - introducing and applying a versatile porphyrin molecular ruler
No full textPorphyrin moieties were rigidly attached to DNA to generate an accurate molecular ruler. Molecular ruler analysis was conducted using steady-state fluorescence, circular dichroism and small angle X-ray scattering spectroscopic techniques, in an attempt to analyse the FRET, exciton coupling and scattering intensity between different porphyrin-porphyrin labelled DNA combinations. A 21-mer test sequence was labelled with a porphyrin in one position on one strand, and seven different positions on seven complementary strands, to overall give seven porphyrin-porphyrin inter-strand combinations. Steady-state fluorescence and circular dichroism spectroscopic analysis of the Soret band revealed individual Watson-Crick bases pair molecular ruler sensitivity. Small angle X-ray scattering attempts between metallated-porphyrin entities did not reveal sufficient scattering at low concentrations, in contrast, an iodinated analogue of the porphyrin system did displayed scattering correlating to different iodine iodine distances. After calibration of the porphyrin system, the moieties were applied to study protein-DNA interactions between Tus, a 36 KDa DNA binding protein, and Ter, a specific 21-mer DNA sequence. Molecular ruler nalysis of the complex required an extended version of the Ter DNA sequence to which modifications were attached. Established FRET pairs FAM and TAMRA were applied to investigate protein-DNA complexation. Native PAGE analysis revealed Tus binds to the extended DNA via a sliding mechanism. Fluorescence analysis of the established FRET pairs identified changes in fluorescence not correlating to changes in FRET, and instead was attributed to emission quenching upon protein binding. Applying the zinc and free base porphyrin version displayed subtle changes in the Soret band circular dichrosim upon complexation, indicating small DNA helical change upon complexation. A 45-mer DNA sequence was designed to form multiple hairpin-duplex conformations with the addition of an appropriate complementary strand. Attaching FRET pairs to the extremes of the DNA sequence enabled multiple DNA conformations, and hence FRET distances to be obtained from one doubly modified DNA sequence. The combinations were characterised by UV-Vis, fluorescence and circular dichroism spectroscopy. Finally, terpyridine labelled DNA sequences selectively formed DNA nanotubes through orthogonal hydrogen bonding and metal complexation interactions. Short DNA strands were designed to self-assemble into long duplexes through a sticky-end approach. Addition of weakly binding metals such as zinc induced the formation of tubular arrays consisting of DNA bundles 50-200 nm wide and 2-50 nm high. TEM displayed additional long distance ordering of the terpyridine-DNA complexes into fibers
The Jonathan Project : acting together in the unwilling
No full textL’exposé reviendra sur un travail clinique réalisé par une équipe, dont l’auteur, en emmenant un enfant atteint d’autisme, Jonathan, rencontrer quotidiennement des dauphins captifs à Cadaqués, en Espagne, durant trois étés consécutifs. L’une des questions qui sera abordée est la suivante : comment créer un espace où le malentendu est toléré, où on peut exister à côté de (et avec) Jonathan, en dehors du langage, et rester dans l’agir sans imposer le sens, sans enfermer l’autre dans notre langage ? Comment faire cause commune quand on ne se comprend pas ? Pour ceux qui entouraient Jonathan, le défi quotidien était de renoncer à toute interprétation hâtive de ses actes « aberrants » et « insensés », de lutter contre une mise en signification brutale et pathologisante, afin de le laisser prendre sa place et nous guider, ce qui supposait aussi d’accepter de se laisser transformer par lui. La maman de Jonathan, partie prenante dans ce projet, nous incitait à questionner nos évidences. Par ses réinterprétations permanentes des comportements de Jonathan, elle nous a amenés à transformer les saillances perceptuelles de l’environnement. Tout cela était probablement nécessaire pour, comme disait Deligny, donner à Jonathan « l’impression qu’il y peut quelque chose, dans ce qui se passe ».The presentation will focus on a clinical work done by a team, including the author, taking a child with autism, Jonathan, meet captive dolphins daily in Cadaqués, Spain, for three consecutive summers. One of the questions that will be addressed is how to create a space where the misunderstanding is tolerated, where one can exist alongside (and with) Jonathan, outside the language, and stay in the act without imposing the sense without locking up the other in our language? How to make common cause when one does not understand himself? For those around Jonathan, the daily challenge was to give up any hasty interpretation of his "aberrant" and "foolish" acts, to fight against a brutal and pathologizing meaning-setting, to let him take his place and guide us. which also supposed to accept to be transformed by him. Jonathan's mom, a stakeholder in this project, encouraged us to question our evidence. Through her permanent reinterpretations of Jonathan's behaviors, she has led us to transform the perceptual salience of the environment. All this was probably necessary for, as Deligny said, to give Jonathan "the impression that there can be something in what is happening"
