Exact simulation of first exit times for one-dimensional diffusion processes

2019

International audience; The simulation of exit times for diffusion processes is a challenging task since it concerns many applications in different fields like mathematical finance, neuroscience, reliability horizontal ellipsis The usual procedure is to use discretization schemes which unfortunately introduce some error in the target distribution. Our aim is to present a new algorithm which simulates exactly the exit time for one-dimensional diffusions. This acceptance-rejection algorithm requires to simulate exactly the exit time of the Brownian motion on one side and the Brownian position at a given time, constrained not to have exit before, on the other side. Crucial tools in this study …

Grammaticalization in Slavic languages

2012

Abstract This article examines the grammaticalisation developments in Slavic languages. The functions of the past tenses lost in northern Slavic are only partially covered by the younger opposition of perfective and imperfective aspect. The only new classes of morphemes that arose in some sub-areas of Slavic are the definite and the indefinite article, both with preliminary, not-yet-grammaticalised stages in some more Slavic varieties. In sum, in Slavic grammaticalization, phenomena have occurred predominantly in the realm of verbal categories; only very few phenomena are related to the noun phrase.

The ὅρος ἤτοι ἐτυμολογία of testamentum and the problem of sources in the Paraphrase of Theophilus

2014

Among the problems long debated by the scholars of the Greek Paraphrase of Justinian’s Institutes, the most interesting was the one concerning the legal sources used by Theophilus; they indeed are not identical with Justinian’s Institutes. Furthermore, a point of view prevails that claims the Antecessor – during the editing of his Paraphrase – could also have taken into consideration Gaius’ Institutes. My speech is based on a close analysis of a well-known passage (Theoph. 2,10 pr. concerning the definition or etymology, ὅρος ἤτοι ἐτυμολογία, of testamentum) and it aims to re-examine how Theophilus managed his sources. The content of the principium is far wider and better articulated compar…

<title>Managing compressed multimedia data in a memory hierarchy: fundamental issues and basic solutions</title>

1998

The purpose of the work is to discuss the fundamental issues and solutions in managing compressed and uncompressed multimedia data, especially voluminous continuous mediatypes (video, audio) and text in a memory hierarchy with four levels (main memory, magnetic disk, (optical or magnetic) on-line/near-line low-speed memory, and slow off-line memory, i.e. archive). We view the multimedia data in such a database to be generated, (compressed), and stored into the memory hierarchy (at the lowest non-archiving level), and subsequently retrieved, (decompressed), and presented. If unused, the data either travels down in the memory hierarchy or it is compressed and stored at the same level. We firs…

Categorization in Discourse and Grammar

2016

This collection of papers addresses new trends in Cognitive Linguistics. Three parts of the book focus on Conceptual Metaphor Theory and Integration Network Analysis. Both the theoretical contributions and the empirical case studies stress the importance of contextual factors in the meaning making processes. They employ qualitative methods to analyze the use of metaphor in political discourse and in the conceptualization of emotions. The data sets include multimodal data, sign languages and co-speech gestures. The fourth part of the book contains two corpus-based studies. The fifth part concentrates on the grammatical categories of passive voice and aspect. One contribution discusses the pr…

Prominence Facilitates Ambiguity Resolution: On the Interaction Between Referentiality, Thematic Roles and Word Order in Syntactic Reanalysis

2011

In two eye-tracking experiments, we investigated the relationship between the subject preference in the resolution of subject-object ambiguities in German embedded clauses and semantic word order constraints (i.e., prominence hierarchies relating to the specificity/referentiality of noun phrases, case assignment and thematic role assignment). Our central research question concerned the timecourse with which prominence information is used and particularly whether it modulates the subject preference. In both experiments, we replicated previous findings of reanalysis effects for object-initial structures. Our findings further suggest that noun phrase prominence does not alter initial parsing s…

Lexicalization (and defrozeness) in the phraseological constellation formed with the nucleus querer

2021

espanolEste articulo pretende contribuir al conocimiento de la fraseologia historica del espanol a partir del analisis de las combinaciones locucionales formadas con el nucleo verbal querer y con sus voces compuestas con bien- y mal-, como bienquerencia, malquerencia, bienquerer y malquerer. Para ello, se abordara la trayectoria historica de las combinaciones prepositivas por bienquerencia de / por malquerencia de / por bienquerer de / por malquerer de, ancladas todas ellas en un proceso de desfraseologizacion, asi como el analisis de la locucion verbal querer bien (o mal), entendida como el punto de origen en la cadena de lexicalizacion de dicha familia fraseologica EnglishThis article aim…

“¡O vos, dubitantes, creed las istorias e los infortunios de los humanales!”. Ficción alegórica y modos de “recontar” en los decires de don Íñigo Lóp…

2017

Los decires narrativos de don Íñigo López de Mendoza representan una de las muestras más sobresalientes de la aclimatación de la ficción alegórica en la literatura medieval hispánica. Uno de los procedimientos centrales en el proceso de composición de estas obras se basa en la selección de recursos estilísticos orientados a recrear una atmósfera de irrealidad. Partiendo, pues, de esta premisa, el objetivo de este estudio se centra en detectar tales elecciones estilísticas e interpretarlas con las herramientas y conocimientos que nos brinda la Filología. De entre el conjunto de recursos expresivos de que dispone la lengua castellana medieval, nos centraremos de modo especial en tres fenómeno…

La iconografía en la era digital: hacia una heurística para el estudio del contenido de las imágenes medievales

2014

Este artículo invita a reflexionar sobre la validez de la iconografía como método para describir los temas representados en las obras artísticas medievales. En esta ocasión, se ha puesto un mayor énfasis en investigar sus implicaciones epistemológicas y los sesgos que resultan del proceso de transformar las imágenes en palabras. El objetivo principal es tratar de que aflore la llamada 'brecha semántica', una especie de barrera que impide representar verbalmente un medio no léxico, como es el visual, de manera satisfactoria y sin mermas. Tras un sucinto recorrido por el pensamiento griego, con un especial interés por la écfrasis, se sugiere que el aparente equilibrio entre las capacidades se…

Notas a la diacronía y la fraseología de andana y traque

2022

El estudio fraseológico del español carece todavía hoy de una obra lexicográfica en la que sus unidades se vean descritas en su historia. Aunque el DHISFRAES llena parcialmente ese vacío, no pocos trabajos han podido detallar la historia de un número importante de unidades fraseológicas. El presente estudio pretende adherirse a ellos, explorando desde los preceptos de la fraseología histórica las unidades fraseológicas que tienen como núcleo andana y traque, ambas palabras diacríticas.
