From Topology to Quasi-Topology. The Complexity of the Notional Domain
2016
This article examines a fundamental metalinguistic construction of the theory of enunciative operations: the notional domain. In particular, we try to explain some elementary topological concepts on which this construction is based and we try to show the key role they play in the description of some basic linguistic operations.

Schistosomes in the north: a unique finding from a prosobranch snail using molecular tools.
2009
article i nfo Samples of schistosome cercariae from three different snail species (Lymnaea stagnalis, Radix auricularia and Valvata (Tropidina) macrostoma) collected from lakes in Central Finland were analyzed using molecular techniques. Based on sequences of ITS region of rDNA, the parasite isolates from L. stagnalis and R. auricularia belong to Trichobilharzia szidati and T. franki, respectively. This confirms a wide distribution of these two species in Europe. On the other hand, the isolates from V. macrostoma represent a unique finding — they belong to yet unknown schistosome species falling into the bird schistosome clade. Therefore, identification of natural final hosts and morphologi…
A work of “total” art. Phenomenology of the Italian memorial in Auschwitz
2016
In 1978 the Italian Association ANED (national association of people formerly deported to nazi camps) starts the design and implementation of a Memorial, to tell the story of the Italian deportation, shaping it with respect to the inner space of one of the existing blocks on the site of the extermination camp in Auschwitz (Block 21). From the first project idea, the art potentiality was assumed as the most suitable instrument for the construction of memory. The Memorial was configured, in fact, as a true work of total art, coincidence of intention and perfect synthesis of the various arts in compliance with the same program: a choral work, a work of artists and intellectuals who, each accor…
Automorphism Groups of Certain Rational Hypersurfaces in Complex Four-Space
2014
The Russell cubic is a smooth contractible affine complex threefold which is not isomorphic to affine three-space. In previous articles, we discussed the structure of the automorphism group of this variety. Here we review some consequences of this structure and generalize some results to other hypersurfaces which arise as deformations of Koras–Russell threefolds.
A new annual species of Bellium (Asteraceae) from the Balearic Islands
2007
A new species, Bellium artrutxensis (Asteraceae: Astereae), is described from the therophytic pastures of southern Minorca (Balearic Islands). The analysis of nuclear ribosomal internal transcribed spacer (ITS) sequences showed that the new taxon was closely related to Bellium bellidioides , but differed with regard to the annual lifespan, the absence of epigeal stolons, and the presence of a patent eglandular indumentum on the leaves. The new taxon shows morphological features that are well suited for the colonization of dry environments with a marked summer drought, and may be of adaptive significance. The new species is diploid (2 n = 18) and shows up to two accessory chromosomes in root…
New physics in $B$ meson mixing: future sensitivity and limitations
2020
The mixing of neutral mesons is sensitive to some of the highest scales probed in laboratory experiments. In light of the planned LHCb Upgrade II, a possible upgrade of Belle II, and the broad interest in flavor physics in the tera-Z phase of the proposed FCC-ee program, we study constraints on new physics contributions to Bd and Bs mixings which can be obtained in these benchmark scenarios. We explore the limitations of this program, and identify the measurement of |Vcb| as one of the key ingredients in which progress beyond current expectations is necessary to maximize future sensitivity. We speculate on possible solutions to this bottleneck. Given the current tension with the standard mo…
Estimation of Vegetation Structure Parameters From SMAP Radar Intensity Observations
2021
In this article, we present a multipolarimetric estimation approach for two model-based vegetation structure parameters (shape A and orientation distribution ψ of the main canopy elements). The approach is based on a reduced observation set of three incoherent (no phase information) polarimetric backscatter intensities (|S HH | 2 , |S HV | 2 , and |S VV | 2 ) combined with a two-parameter (A P and ψ) discrete scatterer model of vegetation. The objective is to understand whether this confined set of observations contains enough information to estimate the two vegetation structure parameters from the L-band radar signals. In order to disentangle soil and vegetation scattering influences on th…
La construcción de los límites a la libertad de expresión en las redes sociales
2016
La generalización de las comunicaciones electrónicas, junto a otras muchas transformaciones, ha facilitado enormemente tanto la comunicación interpersonal como la participación en el debate público a cualquier ciudadano. Como resultado, el pluralismo se ha visto indudablemente enriquecido, así como las posibilidades de recibir información y ser miembro activo de la comunidad política. Otras consecuencias de esta transformación, sin embargo, presentan algunas aristas. Así, esta ampliación del espacio público ha limitado también los espacios de estricta privacidad, incluyendo aquellos ámbitos donde históricamente la expresión de todo tipo de ideas y opiniones quedaban en la intimidad, que cad…
Ethnicity, 2012/6 : Ethnic Identities and Integration of the Society
2012
"Ethnicity" – a peer-reviewed journal was established by the Institute of Philosophy and Sociology (University of Latvia). The journal publishes original works about ethnicity in different fields of knowledge – sociology, history, social linguistics, social psychology, law, political science.
