Three-dimentional tracking of human eye
2003
The study of human movements is the object of numerous searches, among them, the study of the face movements and more particularly the eye kinetics estimate represents an important part. A study realized by artificial vision is presented here. It allows to characterize eye movements in normal shooting condition (mobility of the subject, background lighting). Our approach allows to obtain in a simple way the localization of the iris and the characterization of their movement in the three dimensional shape. The absolute 3D movement of eyeballs and their relative movement with regard to the head are obtained, even if this one are moving.
Analyzing multidimensional movement interaction with generalized cross-wavelet transform
2021
Humans are able to synchronize with musical events whilst coordinating their movements with others. Interpersonal entrainment phenomena, such as dance, involve multiple body parts and movement directions. Along with being multidimensional, dance movement interaction is plurifrequential, since it can occur at different frequencies simultaneously. Moreover, it is prone to nonstationarity, due to, for instance, displacements around the dance floor. Various methodological approaches have been adopted for the study of human entrainment, but only spectrogram-based techniques allow for an integral analysis thereof. This article proposes an alternative approach based upon the cross-wavelet transfor…
Emotional politics on Facebook. An exploratory study of Podemos’ discourse during the European election campaign 2014
2015
The results of the European elections 2014 in Spain were characterized by the outstanding rise of a new party, Podemos, which obtained five seats in the European Parliament, despite being founded few months before the elections. The present study analyzes both the content and the presence of emotions in Podemos’ discourse on Facebook during the European electoral campaign. In particular, the affective content of both the party’s discourse and the comments of its followers will be analyzed through a pragmatic linguistic approach applied to a corpus of 163 posts and 215 followers’ comments. Results show an insistence on positive emotions in the party’s discourse and a prevalence of negative e…
Movement and Emotional Facial Expressions during the Adult Attachment Interview: Interaction Effects of Attachment and Anxiety Disorder
2019
<b><i>Introduction:</i></b> Adult attachment is commonly associated with emotion regulation. Less is known about the nonverbal embodiment of adult attachment. <b><i>Objective:</i></b> We hypothesized that dismissing attachment is related to less movement and fewer facial expressions of emotions, whereas preoccupied attachment is associated with more negative emotional facial expressions. Moreover, the interaction of attachment and the presence of an anxiety disorder (AD) was explored. <b><i>Methods:</i></b> The sample included 95 individuals, 21 with AD without comorbidity, 21 with AD and comorbid major depression (AD-C…
Comparison of spike parameters from optically identified GABAergic and glutamatergic neurons in sparse cortical cultures
2015
We are pleased to note that our publication “Comparison of spike parameters from optically identified GABAergic and glutamatergic neurons in sparse cortical cultures” by Weir et al. (2015) raised some discussion on the feasibility of solely electrophysiological discrimination of distinct neuronal subpopulations in vitro. We agree with Becchetti and Wanke (2015) that their report and our study on the same question were conducted with different technical approaches and that this may explain the observed differences between both studies. Although we obviously recorded a reduced spontaneous neuronal activity under our sparse culture conditions, these conditions were necessary to enable the uneq…
Towards a Critical Understanding of Social Networks for the Feminist Movement: Twitter and the Women’s Strike
2021
L'us intensiu de les plataformes digitals per part del moviment feminista ha sigut identificat com una de les seues caracteristiques claus en l'actualitat. Nombrosos estudis aborden l'us tactic de les xarxes socials per part d'aquest moviment, especialment el 8 de marc a Espanya. Aquest treball estudia els repertoris d'accio dels diferents actors que van participar en la conversa de la Vaga Feminista de 2019, tambe els comptes automatitzats. Els resultats empirics en demostren que Twitter no es un ambit exclusiu del moviment feminista. A mes de les activistes que hi van promoure i van informar sobre la Vaga Feminista, els partits politics van proposar mesures politiques concretes i les facc…
Sofia Nădejde. Of woman's brain and other demons. Anthology of Sofia Nădejde's published writings (eds Maria Cernat and Adina Mocanu). 2019 Ed Parale…
2020
This book review aims to highlight the significance of retreiving the long ignored contributions of Sofia Nadejde’s to the progress of understanding gender inequalities that are deeply rooted in our culture. Through the careful work of reshaping the original texts published between 1881-1885 in Contemporanul. Revista Științifica și Literara, Maria Cernat and Adina Mocanu bring new insights into the genesis and the evolution of local feminist thought by critically situating it within the global feminist movement.
AnMBR, reclaimed water and fertigation: Two case studies in Italy and Spain to assess economic and technological feasibility and CO2 emissions within…
2020
[EN] The use of anaerobic membrane bioreactor (AnMBR) technology on urban wastewater can help to alleviate droughts, by reusing the water and nutrients embedded in the effluent in agriculture (fertigation) in line with Circular Economy principles. The combination of AnMBR and fertigation reduces CO2 emissions due to the organic matter valorization and the partial avoidance of mineral fertilizer requirements. However, both AnMBR and fertigation still face technological and regulatory barriers that need to be overcome. These bottlenecks were tackled within the first Innovation Deal approved by the European Commission in 2016, and gave rise to several case studies on water reuse systems. The r…
Disruption of Eph/ephrin signaling affects migration and proliferation in the adult subventricular zone.
2000
The subventricular zone (SVZ) of the lateral ventricles, the largest remaining germinal zone of the adult mammalian brain, contains an extensive network of neuroblasts migrating rostrally to the olfactory bulb. Little is known about the endogenous proliferation signals for SVZ neural stem cells or guidance cues along the migration pathway. Here we show that the receptor tyrosine kinases EphB1-3 and EphA4 and their transmembrane ligands, ephrins-B2/3, are expressed by cells of the SVZ. Electron microscopy revealed ephrin-B ligands associated with SVZ astrocytes, which function as stem cells in this germinal zone. A three-day infusion of the ectodomain of either EphB2 or ephrin-B2 into the la…
The development of anticipation in the fetus: A longitudinal account of human fetal mouth movements in reaction to and anticipation of touch
2013
Research suggests that fetuses open or close their mouth in relation to directed movements but it is unclear whether mouth opening anticipates the touch or is a reaction to touch, as there has been no analysis so far of (1) the facial area of touch and (2) the sequential ordering of touch and mouth movements. If there is prenatal development of the anticipation of touch we would expect the frequency of fetal mouth opening immediately preceding the arriving hand at the mouth area to increase with fetal age. Fifteen healthy fetuses, eight girls and seven boys, underwent four additional 4-D scans at 24, 28, 32, and 36 weeks gestation. Changes in the frequency of touch for different facial regi…
