Falkland, the promised islands. Approaches to literature of the war
2018
Resumen: El presente artículo propone, en primer lugar, un acercamiento a la construcción nacional del relato sobre las Islas Malvinas. En segunda instancia se realiza un recorrido por la literatura que aborda la guerra de Malvinas a partir de tres focos narrativos: 1982-1989, 1990-2001 y 2002-2017. La periodización responde a las diferentes generaciones pero también a los procesos sociales que han acompañado una transformación política y cultural en Argentina. Finalmente, y como modo de detectar los principales géneros, tramas y conflictos narrativos que han surgido hasta este momento, se analizan las obras más representativas de cada periodo. Abstract: Firstly, this article proposes an ap…
In vitro generated human memory-like T cells are CD95 type II cells and resistant towards CD95-mediated apoptosis
2006
An adaptive immune response implies expansion of activated T cells and subsequent elimination to maintain homeostasis in a process called activation-induced cell death. Some cells, however, differentiate into memory cells and ensure a strong secondary immune response. To analyze the apoptosis phenotype of memory T cells on a cellular and molecular level, we have established an in vitro model of T cell activation and generation of cells phenotypically and functionally similar to memory cells. These long-term cultured T cells show a CD95-resistant phenotype, although they are still sensitive towards TCR/CD3-mediated apoptosis. Biochemical analysis revealed that these cells shift from CD95 typ…
Lo squadrismo
2022
The essay sets out to analyse the genesis of fascist squadrismo, the wave of violence that brought Mussolini to power in 1922. Three levels in particular will be considered. Firstly, an attempt will be made to measure the impact of that violence through the incidence of certain crimes. Then, we will focus on the words used to describe it and the advent of the word 'squadrism'. finally, the fascist memory of squadrism, maintained and elaborated throughout the twenty-year period, will be considered
Avoiding strange attractors in efficient parametric families of iterative methods for solving nonlinear problems
2019
[EN] Searching zeros of nonlinear functions often employs iterative procedures. In this paper, we construct several families of iterative methods with memory from one without memory, that is, we have increased the order of convergence without adding new functional evaluations. The main aim of this manuscript yields in the advantage that the use of real multidimensional dynamics gives us to decide among the different classes designed and, afterwards, to select its most stable members. Moreover, we have found some elements of the family whose behavior includes strange attractors of different kinds that must be avoided in practice. In this sense, Feigenbaum diagrams have resulted an extremely …
Kriterien für die Auswahl von Elektronischen Rechenanlagen für Biomedizinische Forschungsinstitute
1979
Computers are now a recognized tool in biomedical research. They are used for the evaluation of data on one hand and on the other hand for data acquisition and control of experiments. Based on our experience, some suggestions concerning the structure of a mini-computer system suitable for a research laboratory are made. According to the two major classes of application, two sets or requirements arise. We argue that it is effective to use this system for data reduction and evaluation because a large percentage of tasks require program development or at least specific input data handling. Therefore, we call for a multi-user time-sharing system which should be equipped with a set of commands t…
Introduzione di "La Grande Guerra nella Stampa Mondiale"
2020
Il presente libro si configura come un ulteriore prodotto del Network Internazionale Memità che vuole rendere omaggio al centenario della Prima Guerra Mondiale attraverso l’analisi della misura in cui la stampa abbia giocato un ruolo significativo nella costruzione di un’immagine del conflitto ad uso e consumo propagandistico dei governi di riferimento. La stampa di quel periodo si è resa protagonista della narrazione del conflitto e, per la sua natura di strumento di divulgazione, in essa è possibile riscontrare la massima porosità tra il concetto linguaggio e quello di ideologia. Il discorso giornalistico si configura, quindi, come uno dei mezzi d’elezione in cui viene esercitato sul lett…
Heavy ion SEE studies on 4-Gbit NAND-Flash memories
2007
Heavy ion SEE studies on three 4-Gbit NAND-flash memory types were performed at the RADEF facility at the University of Jyvaskyla, Finland with particular emphasis on SEFI differentiation. An error classification for complex memory devices is introduced, and respective cross sections are reported.
A Low Cost Solution for 2D Memory Access
2006
Many of the new coding tools in the H.264/AVC video coding standard are based on 2D processing resulting in row-wise and column-wise memory accesses starting from arbitrary memory locations. This paper proposes a low cost solution for efficient realization of these 2D block memory accesses on sub-word parallel processors. It is based on the use of simple register-based data permutation networks placed between the processor and memory. The data rearrangement capabilities of the networks can further be extended with more complex control schemes. With the proposed control schemes, the networks enable row and column accesses from arbitrary memory locations for blocks of data while maintaining f…
Dual Information Systems: Supporting Organizational Working and Learning by Making Organizational Memory Transparent
1999
The conceptual design of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain-related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This design--use dualism contributes to the deterioration of the interpretive flexibility of information systems. In this article, we outline an information systems architecture called Dual Information Systems (DIS) that incorporates the concepts of an organizational memory information system (OMIS) in a broader framework. DIS help bridge the design--use dualism by providing organizations with a set of services th…
A mixed geometric-systolic approach to parallel molecular dynamics simulations
1995
We have developed a flexible and efficient method of performing molecular dynamics simulations on distributed memory parallel computers. The novel feature is to use simultaneously spatial partitioning and systolic loop approaches according to a strategy which, for a given simulation, adapts itself to the multiprocessor system, allowing to approach optimal performance. The method assures high efficiencies even in situations in which, due to the exceeding large number of processors, the usage of a pure spatial decomposition would be impossible. The algorithm provides as particular cases both the pure spatial partitioning and the pure systolic parallelization schemes, so that its adoption assu…
