Unambiguous recognizable two-dimensional languages
2006
We consider the family UREC of unambiguous recognizable two-dimensional languages. We prove that there are recognizable languages that are inherently ambiguous, that is UREC family is a proper subclass of REC family. The result is obtained by showing a necessary condition for unambiguous recognizable languages. Further UREC family coincides with the class of picture languages defined by unambiguous 2OTA and it strictly contains its deterministic counterpart. Some closure and non-closure properties of UREC are presented. Finally we show that it is undecidable whether a given tiling system is unambiguous.
The Aspects of the Development of Children Speech in their Constructive Activity
2015
One of the most important task of the pre – school pedagogical process is to promote the development of the chidren thinking and imagination. One of the method is the constructive activity whick aim is to develop the children abstractive thinking and imagination. Constructive activity concerns several children processes of cognition, it promotes the perceptivities, thinking, imagination, understanding of the environment, it makes the child to think of the colours, shapes and connections of the items. Construction promotes the development of the speech, it introduces children with mathematical conceptions and the base of geometry. Wider conceptions and understanding about the construction ac…
The effect of long context exposure on cued conditioning and c-fos expression in the rat forebrain
2004
The c-fos expression was used to study the neural substrates of the cued fear conditioning acquisition, preceded by a short exposure versus a long exposure to the conditioning context. A long-context exposure (either during the night or during the day) prior to conditioning, was associated with low freezing in the learning test. Differences in the c-fos expression of CA1, CA3, BL Amygdala, LS and BNST were found between the short- or long-context groups with a pre-exposure before cued conditioning. Ce Amygdala showed no differences in the c-fos expression labeling. We reported the hippocampal c-fos activation during the cued fear conditioning acquisition. Specifically, the CA1 activation co…
Objective, Noninvasive Evaluation of Velopharyngeal Function in Cleft and Noncleft Patients
1998
Objective The purpose of this study was to investigate a new diagnostic method that provides an approach to noninvasive, objective measurement of velopharyngeal movement by acoustic determination of epipharyngeal volume changes with velopharyngeal muscle function. Design This was a case control study, using consecutive samples. Setting This study took place at the Cleft Palate Rehabilitation Center of the University of Mainz, Germany. Patients Subjects were 29 consecutive cleft lip and palate (CLP) patients and 31 controls (21 patients with dysgnathia and 10 healthy volunteers). Intervention A series of transnasal acoustic measurements (pressure wave: 55 dB for 2 milliseconds) of epipharyng…
Mise en scéne et origine perçue des voix hallucinées dans des discours de patients schizophrènes
2008
International audience; This research explores how hallucinated voices appear in schizophrenic patient's narrations. Fourteen narrations of hallucinated patients were studied and are reported. Results show significant differences regarding the prevalence of use in the types of reported speeches, the ones most employed are reported speech and undetermined reported speech as respectively cited. The report mentions that hallucinated discourse is entirely separate and autonomous from the rest of the narration. These results underscore the xenopathic characteristic of hallucinated voices in the elaboration of the narration. These results are discussed for future research in this perspective and …
On the terminology of voice research
1993
Summary This article reviews problems associated with establishment of a scientifically accurate, internationally recognized, multilingual terminology to describe voice. Two strategies for developing terminology are discussed: consensus and dictation. Ontological decisions are considered an integral part of developing terminology. We conclude that terminological problems should be solved by a terminological committee—as yet to be established—as they average from problems in interpreting the literature and the results of voice research. A comprehensive bibliography and audio tape of the multilingual terminology describing voice would help facilitate adaptation and understanding of the terms …
Combinations of discourse markers with repairs and repetitions in English, French and Spanish
2020
Abstract Discourse markers have a central role in planning and repairing processes of speech production. They relate with fluency and disfluency phenomena such as pauses, repetitions and reformulations. Their polyfunctionality is challenging and few form-function mappings are stable cross-linguistically. This study combines a functional and a structural approach to discourse markers and their combination with and within repetitions and self-repairs in native English, French and Spanish, in order to establish the inter-relation between these three fluency-related devices and to find potentially universal patterns of use. Qualitative coding and quantitative analyses of categories of markers a…
On the Shuffle of Star-Free Languages
2012
Motivated by the general problem to characterize families of languages closed under shuffle, we investigate some conditions under which the shuffle of two star-free languages is star-free. Some of the special cases here approached give rise to new problems in combinatorics on words.
Verbal sets and cyclic coverings
2010
Abstract We consider groups G such that the set of all values of a fixed word w in G is covered by a finite set of cyclic subgroups. Fernandez-Alcober and Shumyatsky studied such groups in the case when w is the word [ x 1 , x 2 ] , and proved that in this case the corresponding verbal subgroup G ′ is either cyclic or finite. Answering a question asked by them, we show that this is far from being the general rule. However, we prove a weaker form of their result in the case when w is either a lower commutator word or a non-commutator word, showing that in the given hypothesis the verbal subgroup w ( G ) must be finite-by-cyclic. Even this weaker conclusion is not universally valid: it fails …
Combinatorics of Finite Words and Suffix Automata
2009
The suffix automaton of a finite word is the minimal deterministic automaton accepting the language of its suffixes. The states of the suffix automaton are the classes of an equivalence relation defined on the set of factors. We explore the relationship between the combinatorial properties of a finite word and the structural properties of its suffix automaton. We give formulas for expressing the total number of states and the total number of edges of the suffix automaton in terms of special factors of the word.
