Modeling the insect mushroom bodies: application to a delayed match-to-sample task.
2013
Despite their small brains, insects show advanced capabilities in learning and task solving. Flies, honeybees and ants are becoming a reference point in neuroscience and a main source of inspiration for autonomous robot design issues and control algorithms. In particular, honeybees demonstrate to be able to autonomously abstract complex associations and apply them in tasks involving different sensory modalities within the insect brain. Mushroom Bodies (MBs) are worthy of primary attention for understanding memory and learning functions in insects. In fact, even if their main role regards olfactory conditioning, they are involved in many behavioral achievements and learning capabilities, as …
Predicting mid-air gestural interaction with public displays based on audience behaviour
2020
Abstract Knowledge about the expected interaction duration and expected distance from which users will interact with public displays can be useful in many ways. For example, knowing upfront that a certain setup will lead to shorter interactions can nudge space owners to alter the setup. If a system can predict that incoming users will interact at a long distance for a short amount of time, it can accordingly show shorter versions of content (e.g., videos/advertisements) and employ at-a-distance interaction modalities (e.g., mid-air gestures). In this work, we propose a method to build models for predicting users’ interaction duration and distance in public display environments, focusing on …
Fully automatic face recognition system using a combined audio-visual approach
2005
This paper presents a novel audio and video information fusion approach that greatly improves automatic recognition of people in video sequences. To that end, audio and video information is first used independently to obtain confidence values that indicate the likelihood that a specific person appears in a video shot. Finally, a post-classifier is applied to fuse audio and visual confidence values. The system has been tested on several news sequences and the results indicate that a significant improvement in the recognition rate can be achieved when both modalities are used together.
The impact of a concurrent motor task on auditory and visual temporal discrimination tasks
2016
Previous studies have shown the presence of an interference effect on temporal perception when participants are required to simultaneously execute a nontemporal task. Such interference likely has an attentional source. In the present work, a temporal discrimination task was performed alone or together with a self-paced finger-tapping task used as concurrent, nontemporal task. Temporal durations were presented in either the visual or the auditory modality, and two standard durations (500 and 1, 500 ms) were used. For each experimental condition, the participant’s threshold was estimated and analyzed. The mean Weber fraction was higher in the visual than in the auditory modality, but only for…

To identify factors limiting performance in multitone intensity discrimination, we presented sequences of five pure tones alternating in level between loud (85 dB SPL) and soft (30, 55, or 80 dB SPL). In the “overall-intensity task”, listeners detected a level increment on all of the five tones. In the “masking task”, the level increment was imposed only on the soft tones, rendering the soft tones targets and loud tones task-irrelevant maskers. Decision weights quantifying the importance of the five tone levels for the decision were estimated using methods of molecular psychophysics. Compatible with previous studies, listeners placed higher weights on the loud tones than on the soft tones i…
Alternative surgical management of oroantral fistula using auricular cartilage
2015
One of the clinical complications encountered by oral and maxillofacial surgeons is oroantral communication (OAC) with subsequent formation of oroantral fistula (OAF). Many techniques and treatment modalities have been described for the management of OAC and OAF. There are advantages and disadvantages of all these techniques. We report a 21-year-old male patient who was admitted to our department for the presence of an OAF and was treated using an auricular cartilage graft. This technique may be useful to treat OAF and to provide a solid alveolar bone site for subsequent pre-implant surgery. Key words:Auricular cartilage, implant surgery, oroantral fistula.

Beyond Evidentiality. The epistemic function of the suffix -wa in Aymara
2021
In contrast to the specialized literature (Hardman 1986, 2001; Martinez-Vera 2020), this paper questions the direct evidential function of the sentence-type suffix -wa in «Northern Aymara» (Cerrón-Palomino 2000), an understudied Andean language spoken in the area around Lake Titicaca. By taking a narrow perspective on evidentiality, it proposes that -wa is a modal epistemic marker that indicates the speaker’s high commitment to information. Semantic considerations that support this proposal focus on both the interplay of -wa with other grammatical categories and its distribution within the sentence. Additionally, considerations on the scope properties of the suffix, as applied by Hengeveld …
