Capturing the essence of a textile image in a robust way is important to retrieve it in a large repository, especially if it has been acquired in the wild (by taking a photo of the textile of interest). In this paper we show that a texel-based representation fits well with this task. In particular, we refer to Texel-Att, a recent texel-based descriptor which has shown to capture fine grained variations of a texture, for retrieval purposes.

In neurophysiology, nonhuman primates represent an important model for studying the brain. Typically, monkeys are moved from their home cage to an experimental room daily, where they sit in a primate chair and interact with electronic devices. Refining this procedure would make the researchers' work easier and improve the animals' welfare. To address this issue, we used home-cage training to train two macaque monkeys in a non-match-to-goal task, where each trial required a switch from the choice made in the previous trial to obtain a reward.

Study objectives: To assess spindle activity as possible markers for neurocognitive consequences in children with mild obstructive sleep apnea. Methods: Children aged 6–11 years diagnosed with mild OSA (i.e., an apnea hypopnea index

The crucial role of sleep in physical and mental health is well known, especially during the developmental period. In recent years, there has been a growing interest in examining the relationship between sleep patterns and school performance in adolescents. At this stage of life, several environmental and biological factors may affect both circadian and homeostatic regulation of sleep. A large part of this population does not experience adequate sleep, leading to chronic sleep restriction and/or disrupted sleep–wake cycles.

Negli attuali contesti in cui si enfatizza la funzione di accountability della valutazione, comunicare gli esiti della ricerca valutativa è prioritario, affinché tutti gli stakeholder possano comprenderne processi e risultati. Anche in termini di rendicontazione sociale, la digitalizzazione apre nuovi scenari verso metodi, strumenti e linguaggi comunicativi in grado di ottimizzare le opportunità comunicative offerte dalle tecnologie.

Objectives: To determine whether (1) computer-based self-training for CT colonography (CTC) improves interpretation performance of novice readers; (2) computer-aided detection (CAD) use during training affects learning. Methods: Institutional review board approval and patients’ informed consent were obtained for all cases included in this study. Twenty readers (17 radiology residents, 3 radiologists) with no experience in CTC interpretation were recruited in three centres. After an introductory course, readers performed a baseline assessment test (37 cases) using CAD as second reader.

The outcome of an action plays a crucial role in decision-making and reinforcement learning processes. Indeed, both human and animal behavioural studies have shown that different expected reward values, either quantitatively or qualitatively, modulate the motivation of subjects to perform an action and, as a consequence, affect their behavioural performance. Here, we investigated the effect of different amounts of reward on the learning of macaque monkeys using a modified version of the object-in-place task.

The paper illustrates the first results of an exploratory research on
educational innovation. In the field of research, in-depth interviews were
carried out with university professors, which enabled the reconstruction of
a definition of didactic innovation which, although partial and provisional,
is based on the experience gained in the professional field and takes into
account the potential and limits of Italian academic context.
