El humorismo analítico y la parodia en las compilaciones de crónicas inglesas de Julio Camba: Londres y Aventuras de una peseta

A través de estas páginas se busca el análisis del punto de vista que el periodista Julio Camba arrojó sobre el pueblo inglés en sus crónicas, centrándonos, principalmente, en sus compilaciones de artículos Londres y Aventuras de una peseta. Partiendo de los comentarios sobre su estancia británica, propondremos un análisis sobre el estilo cambiano, sobre todo en su uso de los procedimientos caricaturescos, la detección de automatismos y el empleo del humorismo como marca de estilo. Asimismo, se analizará su enfoque como punto de vista cenital y paródicamente científico.By means of these pages, we want to inquire the point of view that Julio had about the English people in his chronicles. We will pay attention, mainly, in his articles compilation Londres and Aventuras de una peseta. From of the commentaries about his British stay, we will propose an analysis relating to the Camba style, mostly about his use of the caricature method, the detection of automatisms and the utilization of the humour as fingerprint. Additionally, we will analyse his perspective like zenith point of view and like scientific parody

La afasia en los testimonios de conversión súbita

By means of the comparative philological and phenomenological studies of the autobiographical testimonies of Paul Claudel, Manuel García Morente and André Frossard, we inquire into aphasia, an incapacity to talk compared with theophany and the difficulty, when the time comes, to communicate this in a testimonial setting. By comparing this to the mystic tradition, we explore the taxonomy of the ineffable fact in the corpus, as well as the linguistic and narrative possibilities. The aim is to analyse the features and implications of the language when it has to communicate the inexpressible, in this case, one-time appearance of the deity, considering the mystic implications involved.Mediante el estudio comparativo filológico y fenomenológico de los testimonios autógrafos de conversión súbita de Paul Claudel, Manuel García Morente y André Frossard, se pretende indagar en la afasia, entendida como incapacidad de hablar frente a la teofanía y la dificultad de comunicar está en un marco testimonial. En comparación con la tradición mística, se hará un recorrido por la taxonomía de lo inefable en el corpus y se observarán sus posibilidades lingüísticas y narrativas. El objetivo es analizar los rasgos e implicaciones que adquiere el lenguaje a la hora de tener que comunicar un algo inexpresable, en este caso, la aparición puntual de la divinidad con las implicaciones místicas que conlleva

Hypernode reduction modulo scheduling

Software pipelining is a loop scheduling technique that extracts parallelism from loops by overlapping the execution of several consecutive iterations. Most prior scheduling research has focused on achieving minimum execution time, without regarding register requirements. Most strategies tend to stretch operand lifetimes because they schedule some operations too early or too late. The paper presents a novel strategy that simultaneously schedules some operations late and other operations early, minimizing all the stretchable dependencies and therefore reducing the registers required by the loop. The key of this strategy is a pre-ordering that selects the order in which the operations will be scheduled. The results show that the method described in this paper performs better than other heuristic methods and almost as well as a linear programming method but requiring much less time to produce the schedules.Peer ReviewedPostprint (published version

Swing modulo scheduling: a lifetime-sensitive approach

This paper presents a novel software pipelining approach, which is called Swing Modulo Scheduling (SMS). It generates schedules that are near optimal in terms of initiation interval, register requirements and stage count. Swing Modulo Scheduling is an heuristic approach that has a low computational cost. The paper describes the technique and evaluates it for the Perfect Club benchmark suite. SMS is compared with other heuristic methods showing that it outperforms them in terms of the quality of the obtained schedules and compilation time. SMS is also compared with an integer linear programming approach that generates optimum schedules but with a huge computational cost, which makes it feasible only for very small loops. For a set of small loops, SMS obtained the optimum initiation interval in all the cases and its schedules required only 5% more registers and a 1% higher stage count than the optimumPeer ReviewedPostprint (published version

Near-optimal loop tiling by means of cache miss equations and genetic algorithms

The effectiveness of the memory hierarchy is critical for the performance of current processors. The performance of the memory hierarchy can be improved by means of program transformations such as loop tiling, which is a code transformation targeted to reduce capacity misses. This paper presents a novel systematic approach to perform near-optimal loop tiling based on an accurate data locality analysis (cache miss equations) and a powerful technique to search the solution space that is based on a genetic algorithm. The results show that this approach can remove practically all capacity misses for all considered benchmarks. The reduction of replacement misses results in a decrease of the miss ratio that can be as significant as a factor of 7 for the matrix multiply kernel.Peer ReviewedPostprint (published version

Modulo scheduling with reduced register pressure

Software pipelining is a scheduling technique that is used by some product compilers in order to expose more instruction level parallelism out of innermost loops. Module scheduling refers to a class of algorithms for software pipelining. Most previous research on module scheduling has focused on reducing the number of cycles between the initiation of consecutive iterations (which is termed II) but has not considered the effect of the register pressure of the produced schedules. The register pressure increases as the instruction level parallelism increases. When the register requirements of a schedule are higher than the available number of registers, the loop must be rescheduled perhaps with a higher II. Therefore, the register pressure has an important impact on the performance of a schedule. This paper presents a novel heuristic module scheduling strategy that tries to generate schedules with the lowest II, and, from all the possible schedules with such II, it tries to select that with the lowest register requirements. The proposed method has been implemented in an experimental compiler and has been tested for the Perfect Club benchmarks. The results show that the proposed method achieves an optimal II for at least 97.5 percent of the loops and its compilation time is comparable to a conventional top-down approach, whereas the register requirements are lower. In addition, the proposed method is compared with some other existing methods. The results indicate that the proposed method performs better than other heuristic methods and almost as well as linear programming methods, which obtain optimal solutions but are impractical for product compilers because their computing cost grows exponentially with the number of operations in the loop body.Peer ReviewedPostprint (published version

Deciphering the Symbiotic Significance of Quorum Sensing Systems of Sinorhizobium fredii HH103

Quorum sensing (QS) is a bacterial cell-to-cell signaling mechanism that collectively regulates and synchronizes behaviors by means of small diffusible chemical molecules. In rhizobia, QS systems usually relies on the synthesis and detection of N-acyl-homoserine lactones (AHLs). In the model bacterium Sinorhizobium meliloti functions regulated by the QS systems TraI-TraR and SinI-SinR(-ExpR) include plasmid transfer, production of surface polysaccharides, motility, growth rate and nodulation. These systems are also present in other bacteria of the Sinorhizobium genus, with variations at the species and strain level. In Sinorhizobium fredii NGR234 phenotypes regulated by QS are plasmid transfer, growth rate, sedimentation, motility, biofilm formation, EPS production and copy number of the symbiotic plasmid (pSym). The analysis of the S. fredii HH103 genomes reveal also the presence of both QS systems. In this manuscript we characterized the QS systems of S. fredii HH103, determining that both TraI and SinI AHL-synthases proteins are responsible of the production of short- and long-chain AHLs, respectively, at very low and not physiological concentrations. Interestingly, the main HH103 luxR-type genes, expR and traR, are split into two ORFs, suggesting that in S. fredii HH103 the corresponding carboxy-terminal proteins, which contain the DNA-binding motives, may control target genes in an AHL-independent manner. The presence of a split traR gene is common in other S. fredii strains.Spanish Ministerio de Economía y Competitividad (MINECO) BIO2016-78409-
