El libre albedrío: ¿ilusión biológica o realidad metafísica?
2015
El punto fundamental y el verdadero origen de toda la investigación han sido los experimentos de Libet a propósito de la supuesta voluntad libre. La formulación del título de esta tesis quiere encerrar el dilema al que se enfrentan toda la tradición filosófica occidental y parte de las neurociencias actuales: ¿es el libre albedrío una mera ilusión biológica basada en un engaño evolutivo, o es por el contrario una realidad metafísica dotada de existencia independiente que se manifiesta en el conocimiento del ser humano como es el caso de las matemáticas? Los experimentos de Libet, siguiendo la estela de Kornhuber y Deecke, tenían como objetivo el de mostrar que hay una discrepancia temporal …
Incompatibilismo y necesidad metafísica
1997
Algunos filósofos piensan que el conflicto entre la imagen determinista del mundo y la libertad de decisión es irresoluble, y ello les define como incompatibilistas; mientras que otros consideran que hay modos de integrar ambas intuiciones y merecen, pues, el nombre de compatibilistas. El presente artículo pretende mediar en el debate entre estas dos posiciones. Para ello, reflexionaremos acerca de la naturaleza de los vínculos contrafácticos implicados en las relaciones causales que se presuponen tanto en la imagen determinista del mundo como en nuestras intuiciones acerca de la libertad de decisión.

La controversia sobre el determinismo en la física: una controversia sobre estilos
2023
El determinismo en sus diferentes acepciones fue un tema de recurrente discusión en las diferentes comunidades científicas a lo largo de los siglos XIX y XX. Para la física en particular, esta discusión se introduce con la aparición de las primeras leyes estadísticas durante la segunda mitad del siglo XIX y se prolonga hasta la actualidad. Dada la vigencia de este tema, considero que su análisis desde diferentes perspectivas es importante. Por este motivo, presento a continuación una serie de artículos que proponen una mirada de esta controversia a partir de la articulación de varias herramientas conceptuales: los espacios controversiales de Oscar Nudler, los estilos de razonamiento de Ian …
The Images of the Others in Rome (and Geo-Climatic Determinism) (Le Immagini Dell'Altro a Roma (E Il Determinismo Climatico-Ambientale))
2008
In order to explain the anthropic differences of the foreign people, many Roman authors often make use of the well known theory of geo-climatic determinism. Within the frame of this theory Rome becomes the center of the world, i. e., the place of normality, culture, and identity. The Roman identity, however, is not exclusive and is deeply rooted in alterity. In fact, the foundation of Rome, seen as "conluvies convenarum", can always be repeated by means of the conquests of the "Other", who can easily become "identical".
Short synthetic CDR-peptides forming the antibody combining site of the monoclonal antibody against RNA bacteriophage fr neutralize the phage activit…
1996
The construction of a mouse hybridoma FRS2 secreting neutralizing monoclonal antibody specific for RNA bacteriophages fr, MS2 and GA is reported. The genes encoding the variable domains of the monoclonal antibody FRS2 heavy and light chains were cloned and sequenced and the corresponding complementarity determining region (CDR) peptides were chemically synthesized. The CDR-peptides were tested for their ability to neutralize the activity of RNA phage fr and related RNA phages MS2 and GA. The CDR-derived peptides H2, L2 and L3 interacted with the fr phage particles and neutralized fr phage activity. Two of these peptides-H2 and L3 also had the ability to neutralize partly the activity of rel…
ON-LINE CONSTRUCTION OF A SMALL AUTOMATON FOR A FINITE SET OF WORDS
2012
In this paper we describe a "light" algorithm for the on-line construction of a small automaton recognising a finite set of words. The algorithm runs in linear time. We carried out good experimental results on real dictionaries, on biological sequences and on the sets of suffixes (resp. factors) of a set of words that shows how our automaton is near to the minimal one. For the suffixes of a text, we propose a modified construction that leads to an even smaller automaton. We moreover construct linear algorithms for the insertion and deletion of a word in a finite set, directly from the constructed automaton.
Modelling the effects of cropping systems on weed dynamics: the trade-off between process analysis and decision support
2022
Models are essential to synthesize knowledge on weeds and to design integrated weed-management strategies. These models must rank cropping systems as a function of weed infestation, and account for variability in effects to estimate probabilities of success or failure. Three case studies are presented: (1) an empirical static single-equation model that directly relates weed biomass to crop management, with few inputs and parameters, (2) a matrix-based multiannual model predicting a few key weed stages annually, from weed control options and a few parameters, (3) a mechanistic process-based multiannual model predicting detailed soil, crop and weed state variables daily, with an individual-ba…
Free Will and Moral Judgements
2020
Šī pētījuma mērķis bija uzzināt, kādi ir iespējamie faktori, kas ietekmē attiecības starp cilvēku ticību brīvajai gribai un morālajiem spriedumiem. Tika atklāti vairāki pētījumi, kas uzrāda dažādus rezultātus šīm attiecībām, daudzi pētījumi liecina par pozitīviem efektiem, bet ir arī pētījumi, kas liek šīs attiecības apšaubīt. Man radās aizdomas, ka atšķirīgos efektus var radīt tas, kādā kontekstā determinisms tiek apstrādāts cilvēku prātos, jeb tā integrācijas aspekts. Pētījuma empīriskajā daļā tika nolemts veikt salīdzinājumu starp 3 grupām, kurām katrai tika izveidots unikāls determinisma praimings – fatālistiskais (jeb tāds, kurš noliedz izvēles iespējas), zinātniskais (realitāti ir det…
HLA-B27-restricted T cells from patients with ankylosing spondylitis recognize peptides from B*2705 that are similar to bacteria-derived peptides
2003
SUMMARY Ankylosing spondylitis (AS) is an inflammatory systemic disease affecting the spine, sacroiliacal and peripheral joints. Although the aetiology of AS remains unknown, the strong association with the HLA-B27 allele might reflect directly a detrimental effect of the HLA-B27 molecule itself, resulting from its potential capability to present ‘arthritogenic’ peptides to CD8+ T cells. Because some forms of SpA are triggered by enterobacterial infection, such arthritogenic peptides might originate from autologous and/or bacterial proteins triggering cross-reactive CD8+ T cell clones. Intriguingly, two peptides from the second extracellular domain of HLA-B*2705 share sequence homologies wi…
