Seizure Prediction Using EEG Channel Selection Method

2022

Seizure prediction using intracranial electroencephalogram (iEEG) is still challenging because of complicated signals in spatial and time domains. Feature selection in the spatial domain (i.e., channel selection) has been largely ignored in this field. Hence, in this paper, a novel approach of iEEG channel selection strategy combined with one-dimensional convolutional neural networks (1D-CNN) was presented for seizure prediction. First, 15-sec and 30-sec iEEG segments with an increasing number of channels (from one channel to all channels) were sequentially fed into 1D-CNN models for training and testing. Then, the channel case with the best classification rate was selected for each partici…

WRKY gene family drives dormancy release in onion bulbs

2022

Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons. Limited knowledge on the molecular mechanisms that regulate dormancy in onion were available until now. Here, a comparison between uninfected and onion yellow dwarf virus (OYDV)-infected onion bulbs highlighted an altered dormancy in the virus-infected plants, causing several symptoms, such as leaf striping, growth reduction, early bulb sprouting and rooting, as well as a lower abscisic acid (ABA) level at the start of dormancy. Furthermore, by compar…

Sixth graders evaluating online texts : self-efficacy beliefs predict confirming but not questioning the credibility

2023

This study investigated how sixth graders’ credibility evaluation self-efficacy was associated with their ability to evaluate the credibility of online texts. Students (N = 265, Mage = 12.45) worked in a web-based environment, where they read and evaluated two more credible texts and two less credible texts that required confirming and questioning the texts’ credibility, respectively. Students were asked to evaluate the author’s expertise, the author’s benevolence, and the quality of evidence in each text. They were also asked to assess their credibility evaluation self-efficacy during the task. The structural equation model indicated that students’ self-efficacy was positively associated w…

Predicting tire/pavement noise impact reduction using numerical simulation and experimental data for open graded asphalt mixture

2013

The environmental impact of noise from roads and highways traffic is relevant in urban and rural areas. The use of open-graded asphalt pavements reduces significantly the noise, entrapping the acoustic waves inside the porous structure of the material. In this paper we propose a simulation approach in order to predict the acoustic properties of the asphalt mixture from geometrical and topological indicators. In detail we have generated, using a Random Sequential Adsorption model, synthetic samples starting from the same grading and bitumen contents of real samples manufactured in laboratory. We have measured the acoustic adsorption coefficient of the real samples and we have investigated th…

Assessing the Open Trenches in Screening Railway Ground-Borne Vibrations by Means of Artificial Neural Network

2009

Reducing ground borne vibrations in urban areas is a very challenging task in railway transportation. Many mitigation measures can be considered and applied; among these open trenches are very effective. This paper deals with the study of the effect, in terms of reduction of vertical and horizontal displacements and velocities, of the open trenches. 2D FEM simulations have been performed and several open trench configurations have been analysed varying the main geometric features such as width and depth, distance from the rail, thickness of the soil layer over the rigid bedrock, type of the ground, ratio between the depth of the trench, and the thickness of the soil layer. For quantifying t…

Modulation of alcohol consumption using an operant self-administration paradigm: effects of a new dopamine aminoacidic conjugate, Phenylalanine-β(3,4…

2014

Rewarding and reinforcing properties of alcohol have been shown to be mediated by activation of the mesolimbic dopaminergic system. Experimental evidences suggest that mesolimbic dopamine system is hypofunctional in addicted brain; further, reduced dopaminergic activity outlasts somatic signs of withdrawal and may drive craving and relapse. Boosting strategy on dopaminergic neurons could represent a valid therapy. Effects of pharmacological manipulation of brain Dopaminergic receptors by a new dopamine conjugate, Phenylalanine-β(3,4dihydroxyphenyl)-etilamide (DA-Phen), on operant behaviour and on both acute and prolonged withdrawal symptoms during ethanol abstinence have been evaluated. Mal…

Iedzimtas šķielēšanas operācijas laiki un iegūtie rezultāti

2017

Pētnieciskajā darbā tiek apskatīta būtiska un bieži sastopama oftalmoloģiska patoloģija – iedzimta šķielēšana. Bērniem ar šķielēšanu ir ne tikai kosmētisks defekts, kuru nekoriģējot, bērns nevar attiecīgi adaptēties sociālajā vidē, jo īpaši pieaugot, bet, kas ir jo būtiskāk, bērnam ir dažādi redzes traucējumi, tādi kā ambliopija, hipermetropija u.c. Darba mērķis ir noskaidrot iedzimtas šķielēšanas optimālus operācijas laikus un izanalizēt ķirurģiskās ārstēšanas rezultātus. Pētījuma veikšanai tika atlasītas 30 bērnu ambulatorās kartiņas, kas attiecas uz laika periodu no 2007. gada līdz 2011. gadam ar iedzimtas šķielēšanas diagnozi. Atlases kritērijs bija diagnosticēta iedzimta šķielēšana no …

Reciprocal Relations between Adolescents’ Self-Concepts of Ability and Achievement Emotions in Mathematics and Literacy

2021

This longitudinal study examined cross-lagged relations of self-concepts of ability and achievement emotions (i.e., enjoyment, boredom, anxiety) in two central school subjects (i.e., mathematics and literacy). Adolescents (N = 848) reported their achievement emotions and self-concepts of ability four times during Grades 6 and 7. The pattern of results was different for mathematics and literacy subjects. For mathematics the results of random intercept cross-lagged panel models showed a positive reciprocal relationship between self-concepts of ability and enjoyment and a negative reciprocal relationship between self-concept and anxiety. Lower self-concepts of ability in mathematics also predi…

The Role of Adolescents’ and Their Parents’ Temperament Types in Adolescents’ Academic Emotions: A Goodness-of-Fit Approach

2020

Abstract Background Academic emotions (e.g., enjoyment of learning or anxiety) play a significant role in academic performance and educational choices. An important factor explaining academic emotions can be students’ temperament and the goodness-of-fit between their temperament and their social environment, including parents. Objective This study investigated the unique and interactive effects of early adolescents’ and their parents’ temperament types on adolescents’ academic emotions in literacy and mathematics. Method The participants in the study consisted of 690 adolescent–parent dyads. Parents rated their own and their adolescents’ temperaments, and adolescents reported their positive…
