On Infravacua and Superselection Theory
In the DHR theory of superselection sectors, one usually considers states
which are local excitations of some vacuum state. Here, we extend this analysis
to local excitations of a class of "infravacuum" states appearing in models
with massless particles. We show that the corresponding superselection
structure, the statistics of superselection sectors and the energy-momentum
spectrum are the same as with respect to the vacuum state. (The latter result
is obtained with a novel method of expressing the shape of the spectrum in
terms of properties of local charge transfer cocycles.) These findings provide
evidence to the effect that infravacua are a natural starting point for the
analysis of the superselection structure in theories with long-range forces.Comment: LaTeX, 18 pages, spelling errors correcte

Moralidad y Estado en la filosofía política de Fichte
The philosophy of history of 1804 and 1805 enables Fichte to place his
natural right, developed previously at Jena, against a diachronic background.
This means that Fichte does not reason merely synchronically from a timeless
conception of society and state. From a synchronic viewpoint, Fichte cannot
solve the problem of the control of political power because he has to draw on
the assumption of a virtuous ephorate. This assumption is not consistent with
the Fichtean ideal of a philosophy of right completely independent from moral
considerations. Thus, the control of government is possible only if at least a
group of citizens can go beyond the mere rational egoism. This new temporal
conception of the state leads Fichte to think that the problems of consistency
of his theory of Jena are unavoidable, given that a society integrated by egoist
individuals cannot be sustained. However, his later philosophy of history
enables Fichte to state the inexorable annihilation of this type of community and
gives place to an ensuing epoch, when citizens are not self-interested anymore.La filosofía de la historia de 1804 y 1805 permite a Fichte ubicar a su
derecho natural, desarrollado previamente en Jena, en el marco de un trasfondo
diacrónico. Esto significa que Fichte no razona meramente de modo sincrónico,
es decir a partir de una concepción atemporal de la sociedad y el Estado. Desde
un punto de vista sincrónico, Fichte no puede resolver el problema del control
del poder político, porque debe recurrir al supuesto de un eforato virtuoso.
Este supuesto no es consistente con el ideal fichteano de una filosofía del
derecho completamente independiente de consideraciones morales. Por lo
tanto, el control del gobierno es posible solamente si por lo menos un grupo
de ciudadanos puede ir más allá del mero egoísmo racional. Esta concepción
temporal nueva del Estado lleva a Fichte a pensar que los problemas de
consistencia de esta teoría son inevitables, dado que una sociedad integrada
por individuos egoístas no es sostenible. Sin embargo, esta filosofía tardía de
la historia permite a Fichte afirmar la aniquilación inexorable de este tipo de
comunidad y da lugar a la época siguiente, en la que los ciudadanos ya no son
auto-interesados

National Kaohsiung Normal UniversityThe present article is dedicated to the historical analysis of the formant -t- appearing in the Sanskrit neuter s-stem nouns srótas- ‘stream’, rétas- ‘stream; (male) semen’, and †vétas- ‘reed; stick’, as well as the structure and derivation of these nouns. Already Hermann Hirt already proposed that the formant -t- in these nouns was related to the Indo-European t-stems, but alternative interpretations have been put forward as well. Among the existing theories regarding the origin of the formant -t- in these s-stems, Hirt’s theory appears to be the most plausible. A different interpretation regarding the structure and development of their root is proposed in this article, however. Hirt claimed that the normal grade of the root in these nouns was inherited from Indo-European, but an analysis of data suggests that late Indo-European t-stems built to roots of this structure must have had zero grade. The attested full grade must have been introduced only when the reformed roots *srut-, *rit- and *wit- (← **R-t-) were secondarily re-used to build new s-stem nouns
Character-level Transformer-based Neural Machine Translation
Neural machine translation (NMT) is nowadays commonly applied at the subword
level, using byte-pair encoding. A promising alternative approach focuses on
character-level translation, which simplifies processing pipelines in NMT
considerably. This approach, however, must consider relatively longer
sequences, rendering the training process prohibitively expensive. In this
paper, we discuss a novel, Transformer-based approach, that we compare, both in
speed and in quality to the Transformer at subword and character levels, as
well as previously developed character-level models. We evaluate our models on
4 language pairs from WMT'15: DE-EN, CS-EN, FI-EN and RU-EN. The proposed novel
architecture can be trained on a single GPU and is 34% percent faster than the
character-level Transformer; still, the obtained results are at least on par
with it. In addition, our proposed model outperforms the subword-level model in
FI-EN and shows close results in CS-EN. To stimulate further research in this
area and close the gap with subword-level NMT, we make all our code and models
publicly available
Crisis of Language and Decline of Experience in Walter Benjamin and Siegfried Kracauer
El artículo se propone examinar una serie de reflexiones sobre la crisis dellenguaje, en el marco general de una crisis de la experiencia en la Modernidad. Para ello, sugiere como punto de partida la tematización del problema en el viejo Goethe, y muestra luego la recuperación de este abordaje en la literatura del fin-de-siècle alemán y el austríaco. Se detiene a considerar la elaboración del problema en la obra ensayística de Walter Benjamin y en la producción narrativa de Siegfried Kracauer.The article examines a series of reflections on the crisis of the language, wi-thin the broader frame of the crisis of the experience in modernity. It starts with the approach to the problem by the old Goethe, and shows how his pers-pective was recovered in the literature of the German and Austrian fin-de-siècle. The paper analyzes how this problematic was further elaborated in the essayistic works of Walter Benjamin and in Siegfried Kracauer’s novelsFil: Vedda, Miguel Angel.
