FOXP2 and language alterations in psychiatric pathology

2019

Background. From the first reports of the linguist Noam Chomsky it has become clear that the development of language has an important genetic component. Several reports in families have shown the relationship between language disorders and genetic polymorphisms. The FOXP2 gene has been a fundamental piece for the understanding of language development. This gene codes for a transcription factor containing a forkhead domain of DNA binding and participates in the regulation of the expression of a large number of genes involved in the embryonic development of fundamental neuronal structures needed for the development of speech and language. Objective. To present an updated view of the relations…

ECG Analysis for Ventricular Fibrillation Detection Using a Boltzmann Network

2015

Arrhythmias consist on electrical alterations in the heart beat control. They can be identified by means of surface ECG leads. The main goal of this work is to provide a signal classification based on ECG signal waveform in the time-frequency domain especially targeted to Ventricular Fibrillation detection. The use of a classifier based on a Boltzmann network is proposed. However, a previous signal preprocessing is also required so that the Boltzmann network is fed with the appropriate data. In this case, an R-wave detector is used; after that, the Pseudo Wigner-Ville time-frequency distribution is obtained. This distribution is used to train and test the network, which handles it as an ima…

Lubāna ledus loba veidotās reljefa formas Jersikas līdzenumā

2022

Šulcs. R., 2022. Lubāna ledus loba veidotās reljefa formas Jersikas līdzenumā. Rīga, Latvijas Universitāte, 53 lpp. Bakalaura darbā tika pētītas Jersikas līdzenumā sastopamās ledāja reljefa formas. Darba mērķis ir identificēt un raksturot Lubāna ledus loba veidoto reljefa formu izvietojumu, morfoloģiju, iekšējo uzbūvi, ģenēzi un saprast to saistību ar ledus loba uzvirzīšanās un atkāpšanās gaitu. Ledāja reljefa formas tika identificētas un nokartētas, izmantojot augstas izšķirtspējas digitālo reljefa modeli. Lauka darbos tika pētīti teritorijā esošie atsegumi un veikti urbumi ledāja veidotajās reljefa formās. Pētījumā iegūtie rezultāti ļauj interpretēt Lubāna ledus loba dinamiku un zemledāja…

Le cimetière du second âge du Fer de Lailly au-delà de l'eau (Yonne) : découvertes anciennes et fouilles récentes

2023

Die Nekropole von Lailly Au-delà de l’Eau (Departement Yonne) war 1927 entdeckt worden und wurde1934, 1936 und 1937 und zum letzten Mal 2012 teilweise ausgegraben. Die Untersuchung der in den Depots der Museen von Senswiederentdeckten Grabbeigaben und die systematische Aufarbeitung der Grabungsarchive der Société archéologique de Sens habenes ermöglicht, einen Teil der geschlossenen Fundkontexte zu rekonstruieren und eine Belegungschronologie dieser kleinen Nekropolevorzuschlagen, deren großes wissenschaftliches Potenzial noch in situ erforscht werden muss. Die Studie der Grabsitten hat es zudemerlaubt, die Funde in den regionalen und überregionalen soziokulturellen Kontext zu einzuordnen

Neural Classification of Compost Maturity by Means of the Self-Organising Feature Map Artificial Neural Network and Learning Vector Quantization Algo…

2019

Self-Organising Feature Map (SOFM) neural models and the Learning Vector Quantization (LVQ) algorithm were used to produce a classifier identifying the quality classes of compost, according to the degree of its maturation within a period of time recorded in digital images. Digital images of compost at different stages of maturation were taken in a laboratory. They were used to generate an SOFM neural topological map with centres of concentration of the classified cases. The radial neurons on the map were adequately labelled to represent five suggested quality classes describing the degree of maturation of the composted organic matter. This enabled the creation of a neural separator classify…

Maskulinitāte mūsdienu Latvijas vīriešu autoru dzejā

2019

Maģistra darbā tiek pētīta pēdējo desmit gadu (2008–2018) publicētā vīriešu autoru dzeja, ko sarakstījuši autori vecumā no 30–40 gadiem (1979.–1988. gada paaudze), ar nolūku izpētīt to, kādos veidos tiek atainota maskulinitāte šajā mākslas formā, kā šie atainojumi atšķiras gan viena autora daiļrades ietvaros, gan arī starp dažādu autoru darbiem un kā maskulinitātes atveide ir attīstījusies šajā laika ietvarā. Maģistra darbs ir iecerēts kā teorētisks un praktisks ievads maskulinitātes pētīšanai dzejā, kas līdz šim ir tikusi atstāta novārtā, salīdzinot ar femīno aspektu pētīšanu. Pētījumā tiek secināts, ka attiecīgi konkrēta hegemonija un dzimumlomas var visizteiktāk parādīties attiecībā uz s…

Image classification based on 2D feature motifs

2013

The classification of raw data often involves the problem of selecting the appropriate set of features to represent the input data. In general, various features can be extracted from the input dataset, but only some of them are actually relevant for the classification process. Since relevant features are often unknown in real-world problems, many candidate features are usually introduced. This degrades both the speed and the predictive accuracy of the classifier due to the presence of redundancy in the candidate feature set. In this paper, we study the capability of a special class of motifs previously introduced in the literature, i.e. 2D irredundant motifs, when they are exploited as feat…
