Improving estimation of distribution genetic programming with novelty initialization
2021
Estimation of distribution genetic programming (EDA-GP) replaces the standard variation operations of genetic programming (GP) by learning and sampling from a probabilistic model. Unfortunately, many EDA-GP approaches suffer from a rapidly decreasing population diversity which often leads to premature convergence. However, novelty search, an approach that searches for novel solutions to cover sparse areas of the search space, can be used for generating diverse initial populations. In this work, we propose novelty initialization and test this new method on a generalization of the royal tree problem and compare its performance to ramped half-and-half (RHH) using a recent EDA-GP approach. We f…
An Intracortical Implantable Brain-Computer Interface for Telemetric Real-Time Recording and Manipulation of Neuronal Circuits for Closed-Loop Interv…
2021
Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces (BCIs) should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The animal was stereotactically irradiated at the level of the visual cortex upon defining the targe…

Cone-beam computed tomography analysis of root and canal morphology of mandibular premolars in a Spanish population
2014
Purpose: This study aimed to investigate the clinical anatomy of lower premolar roots in a Spanish population by using cone-beam computed tomography (CBCT), correlating findings with patient gender and tooth type. Materials and Methods: Using 70 CBCT images, we evaluated 126 healthy, untreated, well-developed lower premolars. The number and morphology of roots and root canals, and the foramina number were assessed. Results for gender and tooth type were compared using the chi-squared and ANOVA tests. Results: The average length of teeth and roots was significantly higher in men (p=0.00). All 126 premolars had a single root. One canal was found in 83.3% of the premolars, with no gender or to…
Italian inter-society expert panel position on radiological exposure in Neonatal Intensive Care Units.
2020
Abstract Background In the recent years, clinical progress and better medical assistance for pregnant women, together with the introduction of new complex technologies, has improved the survival of preterm infants. However, this result requires frequent radiological investigations mostly represented by thoracic and abdominal radiographs in incubators. This document was elaborated by an expert panel Italian inter-society working group (Radiologists, Paediatricians, Medical Physicists) with the aim to assist healthcare practitioners in taking choices involving radiation exposures of new-born infants and to provide practical recommendations about justification and optimization in Neonatal Inte…
Weakening Forensic Science in Spain: From Expert Evidence to Documentary Evidence*
2012
An amendment in 2002 to the Spanish Code of Criminal Procedure converted into documentary evidence the expert reports prepared by official laboratories aimed at determining the nature, weight, and purity of seized drugs. In most cases, experts are spared from appearance before the courts. This is likely to be extended to other forensic fields. After an overview of criminalistic identification in current forensic science, the objectivity and reliability concepts used by jurists and scientists are considered by comparing the paradigm of individualization with that of likelihood. Subsequently, a detailed critical study is made on the above-mentioned Spanish legal reform, and a comparison is ma…
Humanismo tecnológico: fundamento para una inteligencia artificial responsable
2019
Los rápidos avances en el campo de la inteligencia artificial (IA) en las últimas décadas ponen de relieve la necesidad de incorporar criterios éticos de responsabilidad. Esa incorporación permitirá el planteamiento de una inteligencia artificial responsable (IAR) que tendrá que fundamentarse en la formulación de un nuevo humanismo. Se entiende que a partir de un humanismo tecnológico se podría impulsar la IAR en el contexto tecnológico actual. Los desafíos de la IA imponen el imperativo de plantear un humanismo de este tipo que asuma un compromiso con miras al futuro. En ese sentido, el humanismo tecnológico representa la exigencia de un tiempo de desafíos tecnológicos y a la vez una prem…
Disturbed Exploitation compact Differential Evolution for Limited Memory Optimization Problems
2011
This paper proposes a novel and unconventional Memetic Computing approach for solving continuous optimization problems characterized by memory limitations. The proposed algorithm, unlike employing an explorative evolutionary framework and a set of local search algorithms, employs multiple exploitative search within the main framework and performs a multiple step global search by means of a randomized perturbation of the virtual population corresponding to a periodical randomization of the search for the exploitative operators. The proposed Memetic Computing approach is based on a populationless (compact) evolutionary framework which, instead of processing a population of solutions, handles …
Normativa urbanistica e contratto preliminare
2015
The following article addresses the critical and controversial question concerning the invalidity of the transfer of immovable property not complying with urban planning regulation and the implication of this invalidity in the specific context of the preliminary contract. The paper comments an innovative and recent ruling of the Italian Supreme Court that proposes a crucial change in comparison with the previous decisions made in this matter. The most relevant aspect of the new Supreme Court's guideline, which makes this judgment a leading case, concerns the extension to preliminary contracts of nullity deriving from the conflict with urban planning regulations. This is an important revirem…
The Ivorian Constitutional Council and the supremacy of the Constitution. : study in light of his decisions and opinions
2018
Ivorian constitutional justice, in its current form, is the fruit of the democratization movement launched on the continent from the 1990s. But if elsewhere the exercise of constitutional review immediately became an essential instrument in the effectiveness of the Constitution and the advent of the rule of law, in Côte d'Ivoire, the guarantee of the the Constitution’s supremacy has evolved continuously at an oscillatory rhythm. The constitutionality check is first expressed through a strategy of small steps. The constitutional judge's choice of a narrow interpretation of his attributions produces a daring case law geared towards legitimizing the executive power and its governance. Subseque…
