A novel solution based on scale invariant feature transform descriptors and deep learning for the detection of suspicious regions in mammogram images.

2020

Background: Deep learning methods have become popular for their high-performance rate in the classification and detection of events in computer vision tasks. Transfer learning paradigm is widely adopted to apply pretrained convolutional neural network (CNN) on medical domains overcoming the problem of the scarcity of public datasets. Some investigations to assess transfer learning knowledge inference abilities in the context of mammogram screening and possible combinations with unsupervised techniques are in progress. Methods: We propose a novel technique for the detection of suspicious regions in mammograms that consist of the combination of two approaches based on scale invariant feature …

La competencia textual y mediática en el aula de ELE

2017

Resumen: La habilidad de comprender y producir textos es una de las competencias basicas en la sociedad de la informacion y de la comunicacion (OECD, 2000). Sin embargo, el concepto texto ha evolucionado adquiriendo una versatilidad que rebasa la concepcion tradicional de texto escrito. Para superar este desfase al que la competencia lectora o las destrezas en la comprension y/o expresion oral no llegan, se propone desde Alemania el termino competencia textual y mediatica [1] . La finalidad de esta comunicacion es reflexionar sobre la importancia de esta nueva competencia y dotar al profesorado de herramientas en el tratamiento de la competencia textual en el aula de ELE. Para ello, present…

Does Holistic Processing Require a Large Brain? Insights From Honeybees and Wasps in Fine Visual Recognition Tasks

2018

The expertise of humans for recognizing faces is largely based on holistic processing mechanism, a sophisticated cognitive process that develops with visual experience. The various visual features of a face are thus glued together and treated by the brain as a unique stimulus, facilitating robust recognition. Holistic processing is known to facilitate fine discrimination of highly similar visual stimuli, and involves specialized brain areas in humans and other primates. Although holistic processing is most typically employed with face stimuli, subjects can also learn to apply similar image analysis mechanisms when gaining expertise in discriminating novel visual objects, like becoming exper…

Plasma membrane redox system in the erythrocytes of rowers: Pilot study

2017

The oxidative stress results from a change in the physiological balance between oxidant and antioxidant species. This type of stress is a chemical change in the redox state of cells. The increased production of reactive species is related to an excessive metabolic activation, for example, from an intense physical exercise or an excessive caloric intake (1). In physiological conditions, muscle fibers are provided with an antioxidant system able to keep under control the excessive production of Reactive Oxygen Species (ROS).

ON THE CONCEPT OF THE ENHANCED FON CATALOG COMPILATION

2017

We suppose to compile the enhanced version of FON (Photographic Survey of the Northern Sky) catalog of stellar positions and B-magnitudes in the sky region from -20 to 90 degrees on declination. The photographic base of the project comprises about 5,700 plates obtained at three observatories of the former SU MAO NAS of Ukraine, Kitab observatoryof Uzbekistan and Gissar observatory of Tajikistan. The mean epoch of the catalog is around 1988. The expected limited stellar magnitude is 17.5m. More than 5,400 plates are processed to support the photometric part of the catalog. The plates were shot on the 1.2 m Schmidt telescope in Baldone, Latvia, in the U and V bands. Color data provide the pos…

Las tecnologías de la información y comunicación como herramienta de análisis, evaluación y clasificación de heridas crónicas y neoplásicas. Una revi…

2019

RESUMEN: Objetivo: Analizar el tipo de información aportada por las diferentes tecnologías de la información y comunicación (TIC) disponibles para el análisis, gestión o evaluación de heridas crónicas y lesiones de origen neoplásico, así como su impacto en los cuidados de las mismas, en términos de valoración y resolución de las lesiones. Metodología: Se realizó una revisión sistemática usando las recomendaciones de la Cochrane Collaboration. Se utilizaron las bases de datos MEDLINE (a través de PubMed), Web Of Science y SCOPUS. La estrategia de búsqueda para …

Antimafia e movimenti delle donne. Protagoniste, culture, linguaggi

2016

Il saggio analizza il ruolo giocato dalle donne nei movimenti antimafia a partire dalla loro presenza –cospicua e importante – all’interno dei Fasci dei lavoratori in Sicilia alla fine dell’800 fino alle esperienze del Comitato dei Lenzuoli e dell’Associazione donne per il digiuno nate a Palermo all’indomani delle stragi di Capaci e di via D’Amelio, in cui le figure femminili hanno svolto un ruolo di primo piano sperimentando forme espressive e di mobilitazione civile alternative ed efficaci. L’approccio scelto per l’analisi incrocia gli studi sulla mafia come sistema di potere violento e totalitario con la relazione tra i sessi, intesa come scontro di poteri, in cui svolge un peso determin…

E-maintenance platform: a business process modelling approach

2014

Las tecnologías de la información y la comunicación (TIC) se utilizan cada vez más en la sociedad y en los negocios. Las TIC se han convertido en un elemento clave para el desarrollo empresarial y la mejora de las actividades en todos los departamentos de una organización. Análogamente, la creciente importancia de los Sistemas de Gestión de Mantenimiento asistido por Ordenador (CMMS), Mantenimiento Basado en la Condición (CBM), y la aplicación de dispositivos remotos y funciones como el e-mantenimiento, han abierto grandes posibilidades para la optimización del mantenimiento. Estas técnicas han dado lugar a la aparición de retos tecnológicos, tales como la interoperabilidad entre diferentes…

Characterisation of the microflora contaminating the wooden vats used for traditional Sicilian cheese production

2015

Traditional Sicilian cheese productions are carried out employing traditional wooden vats, called <em>tina.</em> Many studies have highlighted the beneficial role of wooden dairy equipment by contributing to enriching the milk microflora and improving the acidification processes. The present work was undertaken to evaluate the safety of the wooden vats used to coagulate milk. To this purpose, the different microbial populations hosted onto the internal surfaces of the vats used to produce two different stretched cheeses, namely <em>Caciocavallo Palermitano</em> and <em>Vastedda della valle del Belìce DOP</em>, were investigated for the presence of spoilag…
