Fabra i l'Autoritat lingüística al país valencià: l'institut d'estudis valencians (1937-1939)
2020
Davant la dificultat d'acceptar al País Valencià l'autoritat lingüística de l'IEC i la codificació de la llengua catalana, Fabra reconegué en almenys tres declaracions (1918, 1930 i 1937), que corresponia als escriptors valencians la tasca de depurar i de redreçar la llengua i admeté que la constitució d'un centre d'estudis filològics al País Valencià hi podria ajudar. No es pronuncià sobre les Normes de Castelló, però s'interessà per la seua aplicació i, com a president de l'IEC, mantingué una bona relació amb l'Institut d'Estudis Valencians (1937-1939), creat per Francesc Bosch i Morata a imitació de l'IEC. La creació de l'Institut d'Estudis Valencians (= IEV) fou una aspiració constant d…

Memòria i ficció: metaficció historiogràfica en la narrativa de Jesús Moncada
2017
The critical reception of Jesus Moncada's work has been determined by critical debate that opposed rural literature and urban literature in the eighties of the twentieth century. From this perspective, the narrative of Moncada has been identified with the desire to preserve the memory of Mequinensa, disappeared under the water. The paper proposes a reading of author's work from the historiographic metafiction in which the exercise of memory is not to be understood as the desire to preserve against forgetting a lost world, but as a question about mechanisms of understanding of the real one, about conditionings and limits on access to knowledge of history and about relationship between fictio…
Aproximació a la morfosintaxi dels quantificadors en el català del segle XVII
2018
Our paper intends to analyse the sentences which have the quantifiers u (un), 'one', and cada u (cada un), 'everyone', in the Catalan language of the 17th century. This research studies specifically the cases of masculine singular form in external position in detail. The study shows that historically there are morphological alternations between the apocopated form (u) and non-apocopated form (un). But this variation suggests differences in Catalan dialects. Methodologically, the investigation is based on a large corpus of texts from the main Catalan dialects. We describe, classify and quantify the linguistic uses of the quantifiers studied, which reveals that several factors interact in var…
THE CAUCHY DUAL AND 2-ISOMETRIC LIFTINGS OF CONCAVE OPERATORS
2018
We present some 2-isometric lifting and extension results for Hilbert space concave operators. For a special class of concave operators we study their Cauchy dual operators and discuss conditions under which these operators are subnormal. In particular, the quasinormality of compressions of such operators is studied.
A new Framework for the Spectral Information Decomposition of Multivariate Gaussian Processes
2021
: Different information-theoretic measures are available in the literature for the study of pairwise and higher-order interactions in multivariate dynamical systems. While these measures operate in the time domain, several physiological and non-physiological systems exhibit a rich oscillatory content that is typically analyzed in the frequency domain through spectral and cross-spectral approaches. For Gaussian systems, the relation between information and spectral measures has been established considering coupling and causality measures, but not for higher-order interactions. To fill this gap, in this work we introduce an information-theoretic framework in the frequency domain to quantify t…
TGF-β superfamily signaling is essential for tooth and hair morphogenesis and differentiation
2007
Members of the transforming growth factor beta (TGF-beta) superfamily of signaling molecules are involved in the regulation of many developmental processes that involve the interaction between mesenchymal and epithelial tissues. Smad7 is a potent inhibitor of many members of the TGF-beta family, notably TGF-beta and activin. In this study, we show that embryonic overexpression of Smad7 in stratified epithelia using a keratin 5 promoter, results in severe morphogenetic defects in skin and teeth and leads to embryonic and perinatal lethality. To further analyze the functions of Smad7 in epithelial tissues of adult mice, we used an expression system that allowed a controlled overexpression of …
Axonal control of the adult neural stem cell niche.
2014
SummaryThe ventricular-subventricular zone (V-SVZ) is an extensive germinal niche containing neural stem cells (NSCs) in the walls of the lateral ventricles of the adult brain. How the adult brain’s neural activity influences the behavior of adult NSCs remains largely unknown. We show that serotonergic (5HT) axons originating from a small group of neurons in the raphe form an extensive plexus on most of the ventricular walls. Electron microscopy revealed intimate contacts between 5HT axons and NSCs (B1) or ependymal cells (E1) and these cells were labeled by a transsynaptic viral tracer injected into the raphe. B1 cells express the 5HT receptors 2C and 5A. Electrophysiology showed that acti…
Craniomaxillofacial morphology alterations in children, adolescents and adults with neurofibromatosis 1 : a cone beam computed tomography analysis of…
2017
Background Oral manifestations are common in neurofibromatosis 1 (NF1), and include jaws and teeth alterations. Our aim was to investigate the craniomaxillofacial morphology of Brazilian children, adolescents and adults with NF1 using cone beam computed tomography. Material and Methods This study was conducted with 36 Brazilian individuals with NF1 with ages ranging from 4 to 75. The participants were submitted to anamnesis, extra and intraoral exam and cephalometric analysis using cone beam computed tomography. Height of the NF1 individuals was compared to the length of jaws and skull base. The results of the cephalometric measurements of the NF1 group were compared with a control group pa…
FMRI of the Cerebellum: Rostral Paravermal Activation in Tongue and Lip
1998
We investigated with fMRI the cerebellar representation of articulatory vertical movements of the tongue and orofacial muscles in healthy volunteers and its correspondence to the area known to be affected in cerebellar dysarthria. fMRI stimulation is mainly unilateral in agreement with the frequent occurrence of dysarthria in unilateral infarction.
