Automated Diagnostics of Retinal Pathologies Using OCT Volumes
2020
The leading cause of blindness in the population could mostly be the degeneration of the retina caused by the diabetic-related problems and the aging issue. Diabetic retinopathy (DR) and diabetic macular edema (DME) are the main direct causes of vision problems in the labor age citizens of most advanced countries. The elevated number of diabetic people globally indicates that DME and DR will remain to be the principal factor to partial or total vision loss, which affects the lives quality of patients for many years to come and threaten their lives. Therefore, early detection followed by fast treatment procedures of persons with diabetic-related diseases is significant in preventing optical …
Learning what (not) to do: testing rejection and copying of simulated heterospecific behavioural traits
2011
Animals can copy behaviour of heterospecifics (interspecific social learning), but it is not known whether social-learning strategies postulated for conspecific contexts, such as selectively copying individuals (or behaviours) that are more successful or common than the observer, apply here. A recent study found evidence for biased interspecific acquisition of nest site feature preference depending on observed fitness of the demonstrator (clutch size). We experimentally tested whether migratory pied flycatcher, Ficedula hypoleuca, females, given a choice between two novel alternative behavioural traits of nest site feature choice, copy or reject the experimentally induced choice exhibited b…
Quality of Life and Job Loss during the COVID-19 Pandemic: Mediation by Hopelessness and Moderation by Trait Emotional Intelligence
2022
This study contributes to the knowledge on the effects of the COVID-19 pandemic by examining a moderated mediation model in which the impact of job loss over quality of life (QoL) is mediated by hopelessness and moderated by trait emotional intelligence (trait EI). Data were collected from a large nationally representative Italian sample of adult workers (N = 1610), who completed a series of anonymous online questionnaires. Total, direct and indirect effects were estimated through bootstrapped mediated moderation analyses providing 95% bias corrected bootstrap confidence intervals. After controlling for the effects of gender and age range, job loss was found to be negatively associated with…
Cien años de arqueología funeraria en el estrecho de Gibraltar: Nuevas investigaciones en la necrópolis de Baelo Claudia (Tarifa, Cádiz)
2014
En este trabajo abordamos el estudio de la necrópolis oriental de Baelo Claudia (Tarifa, Cádiz) a partir de los trabajos arqueológicos y de interpretación de las antiguas intervenciones que llevamos a cabo desde la Universidad de Alicante. Asimismo, junto con los resultados de la última excavación, se plantean nuevas lecturas sobre el paisaje funerario, la religiosidad y la etnicidad, así como sobre la tipología monumental y los ajuares. The new archaeological research conducted by University of Alicante in the Eastern necropolis of Baelo Claudia (Tarifa, Cádiz) are presented in this paper. Drawing on renewed reinterpretations of ancient excavations which have been enriched with the results…
Geochemical constraints on basalt petrogenesis in the Strait of Sicily Rift Zone (Italy): Insights into the importance of short lengthscale mantle he…
2020
Igneous activity from the late Miocene to historic time (most recently 1891 CE) in the Strait of Sicily has created two volcanic islands (Pantelleria and Linosa) and several seamounts. These volcanoes are dominated by transitional (ol + hy-normative) to alkaline (ne-normative) basaltic lavas and scoriae; volcanic felsic rocks (peralkaline trachyte-rhyolite) crop out only on Pantelleria. Although most likely erupted through continental crust, basalts demonstrate no evidence of crustal contamination and are geochemically similar to oceanic island basalts (OIB). Despite their isotopic similarities, there are considerable compositional differences with respect to major and trace element geochem…
„Na Ukrainie za owych dobrych czasów” – „Przed laty. Powieść ukraińska” Paulina Święcickiego
2020
The forgotten work and life of Paulin Święcicki (1841–1876), a writer from Kiev region and active in Galicia, represents a rare, authentic example of Polish‑Ukrainian cultural border. His debut work entitled 'Przed laty. Powieść ukraińska' (1865), despite being an artistic failure, is an interesting link between the heritage of the Romantic 'Ukrainian School' and the historical vision of Polish Borderlands in With fire and sword by Henryk Sienkiewicz. The creation of the 17th‑century reality of Ukrainian grasslands (noble, rural and Cossack existence), battle scenes (fights against the Tatars), romantic‑melodramatic plot – these are all adapted to a unique Ukrainian (not Polish‑centred) per…
Evidence for a conserved queen-worker genetic toolkit across slave-making ants and their ant hosts
2021
AbstractThe ecological success of social Hymenoptera (ants, bees, wasps) depends on the division of labour between the queen and workers. Each caste is highly specialised in its respective function in morphology, behaviour and life-history traits, such as lifespan and fecundity. Despite strong defences against alien intruders, insect societies are vulnerable to social parasites, such as workerless inquilines or slave-making (dulotic) ants. Here, we investigate whether gene expression varies in parallel ways between lifestyles (slave-making versus host ants) across five independent origins of ant slavery in the “Formicoxenus-group” of the ant tribe Crematogastrini. As caste differences are o…
Effects of microplastics on the functional traits of aquatic benthic organisms: A global-scale meta-analysis
2021
Microplastics are widespread in the aquatic environment and thus available for many organisms at different trophic levels. Many scientific papers focus their attention on the study of the effects of microplastics on different species at individual level. Here we performed a global scale meta-analysis focusing our work on the study of the effect of microplastics on the functional traits of aquatic benthic organisms. Overall, microplastics showed a moderate negative effect on the examined functional traits of benthic organisms. Our results show that some crucial functional traits, such as those linked to behaviour and feeding, appear to be unaffected by microplastics. In contrast, traits rela…
Memristors in Nonlinear Network : Application to Information (Signal and Image) Processing
2021
Memristor is a two-terminal nonlinear dynamic electronic device. Typically, it is a passive nano-device whose conductivity is controlled by the flux, time-integral of the voltage across its terminals, or by the charge, time-integral of the current flowing through it, and it presents interesting features for versatile applications. This thesis considers memristor use as a neighborhood connection for 2D cellular nonlinear or neural network (CNN), essentially for information (image and signal) processing and electronic prosthesis. We develop a model of the memristor based 2D cellular nonlinear networks CNNs compatible to image applications by incorporating memristor in the adjacent neighborhoo…
QUALITATIVE AND QUANTITATIVE BEHAVIORAL TRAITS IN A COMMUNITY OF FURCOCERCARIAE TREMATODES: TOOLS FOR SPECIES SEPARATION?
2008
Many trematode cercariae show distinct behavioral features, which have commonly been used in species identification in combination with morphological characteristics. However, information regarding cercariae behavior has often not been quantified in detail, or it is scattered in the literature, which is why the appropriate level of precision in behavioral identity, particularly in groups of cercariae species showing considerable morphological overlap, has not been properly established. In this study, we investigated one such group, the furcocercariae trematodes, by studying their behavior in a community consisting of 8 species (Diplostomum pseudospathaceum, Ichthyocotylurus variegatus, Coty…
