Impact of chaotic dynamics on the performance of metaheuristic optimization algorithms : An experimental analysis
2022
Random mechanisms including mutations are an internal part of evolutionary algorithms, which are based on the fundamental ideas of Darwin's theory of evolution as well as Mendel's theory of genetic heritage. In this paper, we debate whether pseudo-random processes are needed for evolutionary algorithms or whether deterministic chaos, which is not a random process, can be suitably used instead. Specifically, we compare the performance of 10 evolutionary algorithms driven by chaotic dynamics and pseudo-random number generators using chaotic processes as a comparative study. In this study, the logistic equation is employed for generating periodical sequences of different lengths, which are use…
Local minimizers and gamma-convergence for nonlocal perimeters in Carnot groups
2020
We prove the local minimality of halfspaces in Carnot groups for a class of nonlocal functionals usually addressed as nonlocal perimeters. Moreover, in a class of Carnot groups in which the De Giorgi's rectifiability Theorem holds, we provide a lower bound for the $\Gamma$-liminf of the rescaled energy in terms of the horizontal perimeter.
Network Analysis of Persistent Somatic Symptoms in Two Clinical Patient Samples
2021
OBJECTIVE Previous attempts to group persistent somatic symptoms (PSS) with factor-analytic approaches have obtained heterogeneous results. An alternative approach that seems to be more suitable is the network theory. Compared to factor analysis, which focuses on the underlying factor of symptoms, network analysis focuses on the dynamic relationships and interactions among different symptoms. The main aim of this study is to apply the network approach to examine the heterogeneous structure of PSS within two clinical samples. METHODS The first dataset consisted of N = 254 outpatients who were part of a multicentre study. The second dataset included N = 574 inpatients, both with somatoform di…
Do aetiology, age and cogntive reserve affect executive performance?
2017
Background: The behavioral effect of frontal lesions may be influenced by confounding factors such as aetiology, age and cogntive reserve. Yet no studies have investigated their effects on patients with focal lesions. Objective: Is the grouping of patients with frontal lesions caused by stroke or tumours methodologically appropriate; does age affect cognitive performance, can cognitive reserve protect against cognitive impairment? Patients and Methods/Material and Methods: Cognitive performance was compared across a large sample of frontal patients with stroke, high or low grade tumour, or meningioma. The effect of age, education and NART IQ on the cognitive performance of patients with foc…
Complicanze in chirurgia tiroidea: ipoparatiroidismo sintomatico post-operatorio.Incidenza, note di tecnica chirurgica, prevenzione e trattamento.
2006
Introduction: Total thyroidectomy has a definite role in the management of malignant and benign thyroid disorders, with minimal complications and rare postoperative mortality. Even though thyroid surgery is quite safe, mechanical damage, devascularization or inadvertent removal of the parathyroid glands are possible. The aim of this study is to report report the personal surgical experience and to define some of the pathologic and clinical characteristics of unintentional parathyroidectomy and post-thyroidectomy hypocalcemia Materials and methods: A retrospective-observational study was carried on 313 thyroidectomies from January 2000 to January 2004 (60 males and 253 females), mean age 41 …

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…
Contingency plan for the intensive care services for the COVID-19 pandemic☆☆☆
2020
In January 2020, the Chinese authorities identified a new virus of the Coronaviridae family as the cause of several cases of pneumonia of unknown aetiology. The outbreak was initially confined to Wuhan City, but then spread outside Chinese borders. On 31 January 2020, the first case was declared in Spain. On 11 March 2020, The World Health Organization (WHO) declared the coronavirus outbreak a pandemic. On 16 March 2020, there were 139 countries affected. In this situation, the Scientific Societies SEMICYUC and SEEIUC, have decided to draw up this Contingency Plan to guide the response of the Intensive Care Services. The objectives of this plan are to estimate the magnitude of the problem a…
A quantitative reverse Faber-Krahn inequality for the first Robin eigenvalue with negative boundary parameter
2021
The aim of this paper is to prove a quantitative form of a reverse Faber-Krahn type inequality for the first Robin Laplacian eigenvalueλβwith negative boundary parameter among convex sets of prescribed perimeter. In that framework, the ball is the only maximizer forλβand the distance from the optimal set is considered in terms of Hausdorff distance. The key point of our stategy is to prove a quantitative reverse Faber-Krahn inequality for the first eigenvalue of a Steklov-type problem related to the original Robin problem.
Depression bei Kindern und Jugendlichen: Prävalenz, Diagnostik, ätiologische Faktoren, Geschlechtsunterschiede, therapeutische Ansätze
2007
Die Prävalenzraten für die verschiednen Formen von Depression (depressiven Stimmungen, depressiven Syndromen und Major Depression) haben in den letzten Jahren zugenommen, die Geschlechtsunterschiede mit deutlich höheren Raten für Mädchen haben sich erhöht. Als ätiologische Faktoren für das Auftreten von Depression werden u. a. zunehmende Stressfaktoren, dysfunktionale Bewältigungsstile, ein negatives Körperkonzept und unsichere Bindungsmuster genannt. Unter den verschiedenen therapeutischen Ansätzen hat sich die psychoananlytische Behandlungsmethode als die umfassendste erwiesen. Schlüsselwörter Prävalenzraten - Komorbidität - Stress - Coping - Körperkonzept - Bindung Prevalence rates of th…
