Sobre la identidad y procedencia del poeta Filóxeno y la autoría del ditirambo ???????
2019
El presente estudio pretende resolver la controversia en torno a la identidad y procedencia del poeta Filóxeno, célebre ditirambógrafo del siglo V-IV a.C. Para ello, hemos recopilado todos los testimonios que citan a personajes con el nombre de Filóxeno desde la primera mención de Aristófanes. La investigación ha revelado que existen varios individuos con el mismo nombre y rasgos comunes. No obstante, el examen de estos testimonios revela la existencia de un único autor de ditirambos: Filóxeno de Citera. Además, creemos que este poeta fue el autor del ditirambo ???????, que algunos editores atribuyeron falsamente a Filóxeno de Léucade. Posteriormente, reflexionamos sobre la identidad de Fil…
Refranes y sentencias en la Edad Media: estudio de algunas correspondencias
2015
La denominación de género sentencioso convoca materiales de muy distinta índole: cuentos, fábulas, proverbios, sentencias y refranes que se caracterizan por una vocación sapiencial y didáctica común. Estos términos, si bien albergan realidades textuales distintas, a menudo fueron considerados como voces sinónimas por los autores medievales. El análisis minucioso de las colecciones dedicadas a dos de estos subgéneros, sentencias y refranes, y de las diferentes formas que en ellas aparecen, propicia una reflexión taxonómica cuya meta es una aproximación más exacta a sus afinidades y diferencias, a sus naturalezas intrínsecas y a sus propiedades.
Sic astra mereri. Un’analisi della Controversia de statua viri fortis di Draconzio
2017
Nel contesto dell’Africa vandalica del quinto secolo si distingue una singolare reviviscenza degli studi retorici e, segnatamente, declamatori. Sotto questo profilo, emerge con particolare rilievo uno dei Romulea di Draconzio; si tratta del numero 5 della raccolta, dal titolo Controversia de statua viri fortis. Nel componimento, una esercitazione retorica elaborata in versi esametrici, l’autore riattualizza un motivo topico delle scuole di declamazione, il contrasto tra un dives ed un pauper, arricchendolo di molteplici stratificazioni letterarie, da Virgilio a Lucano soprattutto, che tuttavia non celano lo straordinario interesse draconziano ad intestarsi un certo aggiornamento delle prati…
Nacionālā vērtību sistēma korejiešu sakāmvārdos
2017
Bakalaura darbs “Nacionālā vērtību sistēma korejiešu sakāmvārdos” ir veltīts korejiešu sakāmvārdu izpētei. Katrai tautai ir savas nacionālās īpatnības, kuras nevar piešķirt citām tautām. Sakāmvārds ir folkloras materiāls, kurā atklājas šīs īpatnības. Interese par korejiešu valodas apguvi Latvijā sāka pieaugt tikai šajā desmitgadē. Tas ir galvenais iemesls, kāpēc pētījumu par šo valodu pagaidām nav daudz. Autore izvēlējās korejiešu sakāmvārdus par pētījuma objektu, jo uzskata, ka pilnvērtīga korejiešu valodas apguve bez idiomātisko izteicienu un sakāmvārdu saprašanas ir neiespējama. Darba mērķis ir izpētīt korejiešu sakāmvārdus un izvērtēt to savstarpēju sakarību ar pieņemtām nacionālām vērt…
Automatic Taxonomy Induction based on Word-embedding of Neural Nets
2018
Taxonomy is a knowledge management tool that presents useful information in a well-ordered structure prevents overloading of information on its access and making the information access qualitative. This article is concerned with automatically extracting asymmetrical hierarchical relations from a large corpus and subsequent taxonomy construction by domain independent and semi-supervised system. The methodology relies on the term’s distributional semantics. The algorithm utilizes the word-embedding generated from the vector space model. The model is trained over a large corpus to generate word-embedding of each word in a corpus. Then, the system finds and extracts the hypernyms by using the g…
SingleChannelNet : A model for automatic sleep stage classification with raw single-channel EEG
2022
In diagnosing sleep disorders, sleep stage classification is a very essential yet time-consuming process. Various existing state-of-the-art approaches rely on hand-crafted features and multi-modality polysomnography (PSG) data, where prior knowledge is compulsory and high computation cost can be expected. Besides, it is a big challenge to handle the task with raw single-channel electroencephalogram (EEG). To overcome these shortcomings, this paper proposes an end-to-end framework with a deep neural network, namely SingleChannelNet, for automatic sleep stage classification based on raw single-channel EEG. The proposed model utilizes a 90s epoch as the textual input and employs two multi-conv…
The role of adolescents' temperament in their positive and negative emotions as well as in psychophysiological reactions during achievement situations
2019
Abstract This study examined the role of adolescents' (n = 190) temperament in their emotional reactions in achievement situations. Adolescents rated their temperament (i.e., surgency/extraversion, negative affectivity, effortful control) and completed achievement tasks in Grade 6. They also reported their emotions before and during challenging and non-challenging tasks. In addition, adolescents' autonomic nervous system reactions (i.e., skin conductance levels) were recorded. The results showed that high effortful control was related to higher levels of positive emotions independent of the degree of task difficulty. Low negative affectivity and high effortful control were related to lower …
Comparison of Machine Learning Methods in Stochastic Skin Optical Model Inversion
2020
In this study, we compare six different machine learning methods in the inversion of a stochastic model for light propagation in layered media, and use the inverse models to estimate four parameters of the skin from the simulated data: melanin concentration, hemoglobin volume fraction, and thicknesses of epidermis and dermis. The aim of this study is to determine the best methods for stochastic model inversion in order to improve current methods in skin related cancer diagnostics and in the future develop a non-invasive way to measure the physical parameters of the skin based partially on the results of the study. Of the compared methods, which are convolutional neural network, multi-layer …
Alleviating Class Imbalance Problem in Automatic Sleep Stage Classification
2022
For real-world automatic sleep-stage classification tasks, various existing deep learning-based models are biased toward the majority with a high proportion. Because of the unique sleep structure, most of the current polysomnography (PSG) datasets suffer an inherent class imbalance problem (CIP), in which the number of each sleep stage is severely unequal. In this study, we first define the class imbalance factor (CIF) to describe the level of CIP quantitatively. Afterward, we propose two balancing methods to alleviate this problem from the dataset quantity and the relationship between the class distribution and the applied model, respectively. The first one is to employ the data augmentati…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
