Autostereoscopic Three-Dimensional Neuronavigation to the Sella: Technical Note.

2017

Background A drawback of conventional neuronavigation is the necessity of focusing on two-dimensional images in 3 planes at the same time to determine one's position in the operating field. A solution would be to merge the images into a single three-dimensional (3D) image that mirrors the actual anatomy. The introduction of holographic glassless 3D monitors paved the way to 3D navigation. We present our experience with 3D neuronavigation as exemplified by navigation to and within the sella. Methods Operative planning was conducted with a navigation system using cranial computed tomography and magnetic resonance imaging. The image data sets were processed by the prototype Clariti 3D system t…

Comparison of service tactic formation on players’ movements and point outcome between national and beginner level padel

2021

The aim of this study was to analyze the influence of service tactic formation on players’ movements and point outcome at two different performance levels. The sample contained 2,148 points corresponding to 18 matches from two male padel indoor tournaments. Players were classified according to their game level: high-level (N = 36; age = 33.3 ± 6.9 years) and beginner (N = 36; age = 35.4 ± 6.8 years). Variables pertaining to service tactic formation (conventional or Australian), point outcome and movement patterns were analysed from the matches through systematic observation. The results showed how high-level players used a significantly higher percentage of the Australian formation than beg…

Path Following in Non-Visual Conditions.

2018

Path-following tasks have been investigated mostly under visual conditions, that is when subjects are able to see both the path and the tool, or limb, used for navigation. Moreover, only basic path shapes are usually adopted. In the present experiment, participants must rely exclusively on continuous, non-speech, and ecological auditory and vibrotactile cues to follow a path on a flat surface. Two different, asymmetric path shapes were tested. Participants navigated by moving their index finger over a surface sensing position and force. Results show that the different non-visual feedback modes did not affect the task's accuracy, yet they affected its speed, with vibrotactile feedback causin…

Smile esthetics from odontology students' perspectives

2013

ABSTRACT Objectives: To analyze the perception of smile esthetics and its alterations in dental degree students; to determine whether there are differences in that perception among students in different study years on those courses and between genders; and to determine if the circumstance of having received prior orthodontic treatment could influence that perception. Material and Methods: Students (n = 192) in different study years of the dental degree course at the University of Valencia, Spain, analyzed two photographs of a patient in which, by means of computer software, midline diastema, upper and lower midlines, crown length of the maxillary right central incisor, occlusal cant, and “g…

Age and Grip Strength Predict Hand Dexterity in Adults.

2015

In the scientific literature, there is much evidence of a relationship between age and dexterity,\ud where increased age is related to slower, less nimble and less smooth, less coordinated\ud and less controlled performances. While some suggest that the relationship is a direct consequence\ud of reduced muscle strength associated to increased age, there is a lack of research\ud that has systematically investigated the relationships between age, strength and\ud hand dexterity. Therefore, the aim of this study was to examine the associations between\ud age, grip strength and dexterity. 107 adults (range 18-93 years) completed a series of hand\ud dexterity tasks (i.e. steadiness, line tracking…

Equivalence Problem of Composite Class Diagrams

2001

Multiplicity constraints in a UML composite class diagram may be inconsistent. An algorithm is given for eliminating all such inconsistencies. Using this algorithm an algorithm is constructed which for two given composite class diagrams solves the equivalence problem. These algorithms can be embedded in CASE tools for automated detection of multiplicity inconsistencies.

Sign Languages Recognition Based on Neural Network Architecture

2017

In the last years, many steps forward have been made in speech and natural languages recognition and were developed many virtual assistants such as Apple’s Siri, Google Now and Microsoft Cortana. Unfortunately, not everyone can use voice to communicate to other people and digital devices. Our system is a first step for extending the possibility of using virtual assistants to speech impaired people by providing an artificial sign languages recognition based on neural network architecture.

Between Life and Existence. Heidegger’s Aristotelianism and the Question of Animality

2021

This paper starts by investigating the Aristotelian roots of Heidegger’s stance toward animal life from 1924 lecture course “Basic concepts of Aristotelian philosophy” to 1929/30 lecture course “The fundamental concepts of Metaphysics”. In following Aristotle, Heidegger displays the ontological transition from life to existence as grounded to the peculiar linguistic ability of human beings. In doing that, both Heidegger and Aristotle seem to establish a connection between an existential faculty (logos) and the apparently dominant position occupied by our species. On the other side, though, to be endowed with logos means for human beings to be able to de-centre themselves in recognizing the …

QuBiLs-MAS method in early drug discovery and rational drug identification of antifungal agents

2015

The QuBiLs-MAS approach is used for the in silico modelling of the antifungal activity of organic molecules. To this effect, non-stochastic (NS) and simple-stochastic (SS) atom-based quadratic indices are used to codify chemical information for a comprehensive dataset of 2478 compounds having a great structural variability, with 1087 of them being antifungal agents, covering the broadest antifungal mechanisms of action known so far. The NS and SS index-based antifungal activity classification models obtained using linear discriminant analysis (LDA) yield correct classification percentages of 90.73% and 92.47%, respectively, for the training set. Additionally, these models are able to correc…
