SOM-Based Class Discovery for Emotion Detection Based on DEAP Dataset
2018
This paper investigates the possibility of identifying classes by clustering. This study includes employing Self-Organizing Maps (SOM) in identifying clusters from EEG signals that could then be mapped to emotional classes. Beginning by training varying sizes of SOM with the EEG data provided from the public dataset: DEAP. The produced graphs showing Neighbor Distance, Sample Hits, and Weight Position are examined. Following that, the ground-truth label provided in DEAP is tested, in order to identify correlations between the label and the clusters produced by the SOM. The results show that there is a potential of class discovery using SOM-based clustering. It is then concluded that by eval…
Indications for Computer-Assisted Surgery in Otorhinolaryngology
1998
Indications for the use of computer-assisted surgery (CAS) in otorhinolaryngology can be grouped into several domains including the following: difficult cases involving the anterior, middle, and posterior skull base, especially the rhinobasis or laterobasis, and diseases of the petrous bone, the infratemporal fossa, the retromaxillar space, and the orbit; extended paranasal sinus surgery and revision cases with surgically altered anatomic landmarks; and use for educational purposes where CAS can provide better instruction in surgical anatomy by relating the surgical field to radiological sectional images. A new field for CAS is surgery of the inferior neck soft tissues or pathologic process…
State of the art and clinical recommendations in periapical implant lesions. 9th Mozo-Grau Ticare Conference in Quintanilla, Spain.
2016
This manuscript summarizes the statements and clinical recommendations in periapical implant lesions, as per the state of the art and expert opinion agreement among the participants in the 9th Mozo-Grau Conference 2016 held in Quintanilla (Valladolid, Spain). The current status of the concept, frequency, etiology, diagnosis, clinical classification, surgical procedure and prognosis are described. If following implant placement localized pain develops in the periapical area, with or without radiographic changes, the diagnosis of periapical implant lesion should be suspected. It is important to monitor the condition in order to identify any change in its evolution. Radiological changes in the…
Interobserver and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography
2021
Background Data regarding the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography are missing in the current literature. This study assessed the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography (CBCT). Material and Methods In 107 patients, 130 salivary glands (65 parotid and 65 submandibular) with clinical signs of obstruction were assessed by four independent observers; 2 residents OMFS and 2 experienced OMFS. The observers analyzed the CBCT images and determined the absence or presence of one or more salivary stones in the affected gland. This proc…
Editorial 1/2016
2015
It is with great pleasure to wish all our readers, authors and reviewers a happy and healthy new year 2016! Dentomaxillofacial Radiology is fortunate to look back on some rather successful years. Our speciality, that is, oral and maxillofacial (radiological) imaging gained increasing importance over the past decade, which is predominantly a result of the success of CBCT. Lately, we have seen an increasing number of articles (e.g. Petersen Johan Aps Gang Li
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…
Chest CT in COVID-19 Pneumonia: Potentials and Limitations of Radiomics and Artificial Intelligence
2021
SARS-CoV-2 epidemics has resulted in an unprecedented global health crisis causing a high number of deaths with pneumonia being the most common manifestation. Chest CT is the best imaging modality to identify pulmonary involvement, but unfortunately there are no pathognomonic features for COVID-19 pneumonia, since many other infectious and non-infectious diseases may cause similar alterations. The adoption of artificial intelligence in biomedical imaging has the potential to revolutionize the identification, management, and the patient’s outcome. If adequately validated, it could be used as a support with predictive and prognostic purposes in symptomatic patients but also as a screening tes…
Deficiencias epistemológicas en la enseñanza habitual de los conceptos de campo y potencial eléctrico
1997
This article intends to analyse up to what extent the scarce learning produced when introducing the basic concepts on electrostatics is due to deficiencies and inadequacies in its routine teaching. So, on the one hand, we analyse what have been the principal epistemological leaps forward in the making of electricity as a science. On the other hand, we analyse Physics books and the teachers’ opinions.
Injertarse en la Historia. Gesto creativo y estrategias de reapropiación en el activismo global.
2013
Resumen: Este trabajo trata de desentranar los modos en que los actuales movimientos sociales impulsan un proceso de reapropiacion que se extiende en diversos ambitos. Ensamblandose a un sistema de comunicacion en redes y adoptando nuevas formas de intervencion basadas en el modelo de guerrilla artistica, estos grupos antagonistas tratan de recuperar para el individuo su rol de sujeto social consciente. A la luz de estas premisas y a partir de algunos casos particulares, senalaremos los radios de accion de estos movimientos centrados en reapropiarse del lenguaje usurpado por la gramatica del mercado, recuperar los espacios publicos para el uso colectivo y reinscribirse en el curso de la His…
Clinical repercussions and epidemiological considerations of supernumerary canines : a 26 case series
2019
Background To establish the prevalence of supernumerary canines (SNC) in a sector of the population of Madrid (Spain), as well possible complications associated with this unusual developmental variation. Material and Methods This observational study was performed between 2005 and 2017, among 21,615 patients seeking dental treatment at the Faculty of Dentistry, Complutense University of Madrid (Spain), and at the Virgen de la Paloma Hospital, Madrid (Spain); 22 patients with 26 SNCs were diagnosed. These 22 patients underwent clinical and radiological exploration, registering patient data. Results SNCs presented a prevalence of 0.10% of the study population. The supernumerary teeth (SNT) wer…
