Compression-based classification of biological sequences and structures via the Universal Similarity Metric: experimental assessment.
2007
Abstract Background Similarity of sequences is a key mathematical notion for Classification and Phylogenetic studies in Biology. It is currently primarily handled using alignments. However, the alignment methods seem inadequate for post-genomic studies since they do not scale well with data set size and they seem to be confined only to genomic and proteomic sequences. Therefore, alignment-free similarity measures are actively pursued. Among those, USM (Universal Similarity Metric) has gained prominence. It is based on the deep theory of Kolmogorov Complexity and universality is its most novel striking feature. Since it can only be approximated via data compression, USM is a methodology rath…
Ownership protection of plenoptic images by robust and reversible watermarking
2018
Abstract Plenoptic images are highly demanded for 3D representation of broad scenes. Contrary to the images captured by conventional cameras, plenoptic images carry a considerable amount of angular information, which is very appealing for 3D reconstruction and display of the scene. Plenoptic images are gaining increasing importance in areas like medical imaging, manufacturing control, metrology, or even entertainment business. Thus, the adaptation and refinement of watermarking techniques to plenoptic images is a matter of raising interest. In this paper a new method for plenoptic image watermarking is proposed. A secret key is used to specify the location of logo insertion. Employing discr…
Discrimination of physiological tremor from pathological tremor using accelerometer and surface EMG signals.
2020
BACKGROUND AND OBJECTIVE: Although careful clinical examination and medical history are the most important steps towards a diagnostic separation between different tremors, the electro-physiological analysis of the tremor using accelerometry and electromyography (EMG) of the affected limbs are promising tools. METHODS: A soft-decision wavelet-based decomposition technique is applied with 8 decomposition stages to estimate the power spectral density of accelerometer and surface EMG signals (sEMG) sampled at 800 Hz. A discrimination factor between physiological tremor (PH) and pathological tremor, namely, essential tremor (ET) and the tremor caused by Parkinson’s disease (PD), is obtained by s…
Energy saving in WWTP: Daily benchmarking under uncertainty and data availability limitations
2016
Efficient management of Waste Water Treatment Plants (WWTPs) can produce significant environmental and economic benefits. Energy benchmarking can be used to compare WWTPs, identify targets and use these to improve their performance. Different authors have performed benchmark analysis on monthly or yearly basis but their approaches suffer from a time lag between an event, its detection, interpretation and potential actions. The availability of on-line measurement data on many WWTPs should theoretically enable the decrease of the management response time by daily benchmarking. Unfortunately this approach is often impossible because of limited data availability. This paper proposes a methodolo…

SMS Messages in a Daily Finnish Newspaper : The Contect of Proverb Performances
2017
The article focuses on Finnish proverbs as a part of contemporary colloquial written language in everyday use and context. The article offers a view on what is happening with proverbs in the vernacular in Finnish everyday life. Most traditional Finnish proverbs originate from an agrarian context and still use agrarian language, even if nowadays they live in a new context with a new meaning. As empirical material this article uses a special case that demonstrates the use of proverbs in one Finnish newspaper: proverbs in SMS messages published as a letter to the editor in a newspaper. *** Avtorica se osredinja na finske pregovore kot del sodobnega pogovornega pisnega jezika v vsakdanji rabi i…
Opposite Ends: widows' narratives of contemporary late life
2020
The life course perspective frames this study of contemporary late life. Thematic narrative analysis is employed to analyse the stories of 16 Finnish widows aged 79–89 years (Moving in Old Age: Transitions in Housing and Care research project) in order to explore the experiences related to growing old. The results indicate two kinds of narratives: nostalgic reminiscences about a happy past are typical of the retiring to solitude story, characterised by experiences of life nearing its end and of letting go; and those inclined towards the keeping up narrative are still seeking new experiences and playing active roles in everyday life. Both kinds of stories encompass well-being, in spite of…
Temporality in cosmopolitan solidarity : Archival activism and participatory documentary film as mediated witnessing of suffering at Europe’s borders
2019
This article develops and extends the idea of cosmopolitan solidarity to temporality through a case study of archival activism and participatory film-making. It examines mediated witnessing within the Italian online audiovisual archive Archivio delle memorie migranti, which documents and archives the experiences of contemporary migrants in Italy. The moral basis of Archivio delle memorie migranti is cosmopolitan solidarity, which is usually understood as a practice that crosses spatial and communal boundaries. However, the ethics of solidarity also bridges past, present and future generations. Through the case of Archivio delle memorie migranti, this article demonstrates the significance o…
Memoria autobiográfica, cambios cognitivos y regulación emocional en el envejecimiento
2017
Navegar por nuestros recuerdos es un aspecto básico y esencial en el funcionamiento humano, y supone incontables beneficios en todas las etapas, y en especial en el envejecimiento, ya que contribuye a desarrollar el self, ayuda a las personas a orientarse en el mundo y a perseguir sus objetivos basándose en experiencias del pasado que fueron superadas, y además, contribuye a las relaciones sociales (Conway 1996; Conway y Rubin, 1993). Dentro del sistema de memoria autobiográfica existen dos tipos de conocimiento: el componente episódico, formado por eventos personales del pasado con contenido específico (como detalles sensorio-perceptivos, imágenes, emociones y pensamientos), y el component…
Búsqueda de compuestos con potencial terapéutico para la enfermedad de Parkinson y estudio de la relación entre la enfermedad de Parkinson y la Diabe…
2022
La enfermedad de Parkinson (EP) es la segunda enfermedad neurodegenerativa más frecuente. Actualmente, la EP no tiene cura, y las terapias existentes solo son capaces de tratar los síntomas de esta enfermedad, pero no de ralentizar o de parar su progresión. Con el objetivo de descubrir nuevos fármacos que pudieran ser útiles para tratar esta enfermedad, hemos realizado un rastreo a gran escala, evaluando los compuestos incluidos en la quimioteca Prestwick (1120 compuestos). Para ello, estudiamos el efecto de estos compuestos sobre la actividad motora en un modelo de la EP en Drosophila basado en la mutación del gen DJ-1beta (ortólogo del gen humano DJ-1, cuya mutación es causante de casos f…
