Efficacy, safety and tolerability of aripiprazole in bipolar disorder: An updated systematic review and meta-analysis of randomized controlled trials
2017
Numerous studies have investigated aripiprazole as a treatment for bipolar disorder (BD). therefore we conducted this comprehensive meta-analysis to investigate the efficacy and safety profile of aripiprazole in treating BD. Two authors conducted systematic searches of PubMed and ScienceDirect from inception until May 14th, 2017. Randomized controlled trials (RCTs) of people with BD who received aripiprazole were included. A total of 20 RCTs met the eligibility criteria, including two which investigated the efficacy of aripiprazole versus haloperidol (aripiprazole = 340; haloperidol = 337), three which compared aripiprazole versus lithium (aripiprazole = 208; lithium = 212), and 15 with mul…
Automatic Reengineering in MDA Using Rewriting Logic as Transformation Engine
2005
Legacy systems are information systems that have been developed by means of methods, tools and database management systems that have become obsolete, but they are still being used due to their reliability. As time goes on, the maintenance of this software becomes more complex, expensive and painful. The MOMENT framework supports automatic formal model transformations in MDA. This model transformation approach is based on the algebraic specification of models and benefits from mature term rewriting system technology to perform model transformation using rewriting logic. In this paper, we present how we apply this formal transformation mechanism to recover a legacy relational database, obtain…

Signal Spectrum-Based Machine Learning Approach for Fault Prediction and Maintenance of Electrical Machines
2022
Industrial revolution 4.0 has enabled the advent of new technological advancements, including the introduction of information technology with physical devices. The implementation of information technology in industrial applications has helped streamline industrial processes and make them more cost-efficient. This combination of information technology and physical devices gave birth to smart devices, which opened up a new research area known as the Internet of Things (IoT). This has enabled researchers to help reduce downtime and maintenance costs by applying condition monitoring on electrical machines utilizing machine learning algorithms. Although the industry is trying to move from schedu…
Digital Twin framework for automated fault source detection and prediction for comfort performance evaluation of existing non-residential Norwegian b…
2023
Numerous buildings fall short of expectations regarding occupant satisfaction, sustainability, or energy efficiency. In this paper, the performance of buildings in terms of occupant comfort is evaluated using a probabilistic model based on Bayesian networks (BNs). The BN model is founded on an in-depth anal- ysis of satisfaction survey responses and a thorough study of building performance parameters. This study also presents a user-friendly visualization compatible with BIM to simplify data collecting in two case studies from Norway with data from 2019 to 2022. This paper proposes a novel Digital Twin approach for incorporating building information modeling (BIM) with real-time sensor data…
Medicinal Plants for Insomnia Related to Anxiety: An Updated Review.
2021
AbstractSleep disorders are common among the general population and can generate health problems such as insomnia and anxiety. In addition to standard drugs and psychological interventions, there are different complementary plant-based therapies used to treat insomnia and anxiety. This review aimed to find and examine the most recent research on the use of herbal medicines for treating anxiety and insomnia as compiled from clinical trials, as well as to assess the safety and efficacy of these medicines and to elucidate their possible mechanisms of action. The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included “sleep d…
Enabling transformative value creation through online weight loss services
2020
PurposeThis study aims to understand how online weight loss services could help customers achieve a durable change. The particular focus is on exploring the roles of value co-creation and well-being outcomes in reinforcing the transformative value potential, which is argued to be realized as customers’ intentions to continue a healthier lifestyle after the service period has ended.Design/methodology/approachData was collected from the participants of an online weight loss service (n = 498), and a conceptual research model was tested using structural equation modelling.FindingsThe results imply that compliance with the guidelines and social support are two value co-creation activities that c…
La verifica di un de restauro come criterio per una riflessione necessaria. La Villa Romana del Casale di Piazza Armerina (Enna), dal 1997 nella Worl…
2022
Nei pressi di Piazza Armerina (Enna), all'inizio del sec. XX, sono stati scoperti i resti della Villa romana del Casale (IV sec. dC), con ricchi pavimenti musivi. Dopo il primo restauro, verso la metà degli anni Cinquanta del sec. XX, l'architetto F. Minissi e C. Brandi progettarono una protezione stabile e un sistema per la fruizione dei resti della villa. Il tetto è stato realizzato con materiali moderni: profili in alluminio e lastre di vetro e perspex, che evocavano le antiche volurne, pur mantenendo l'autenticità dei resti. La sistemazione, per mancanza di manutenzione, è stata fonte di degrado per i mosaici, e infatti dal 2007 sono iniziati i lavori per la loro distruzione e sostituzi…
Il patrimonio delle ville di Bagheria, fra storia, conservazione e valorizzazione
2016
Il volume di M.A. Giusti (a cura di), Ville lucchesi, d’Italia, del mondo Conoscenza e cura delle dimore di campagna e dei loro giardini, pubblicato a Lucca nel 2016, rappresenta il primo studio che indaga in maniera completa la particolare tipologia della villa e il suo contesto, non solo in un ambito italiano, ma nel mondo. Assieme alle ville lucchesi, che con l’associazione Ville e Palazzi di Lucca ha promosso l’iniziativa editoriale, sono indagate le ville Venete, Torinesi, del Lazio, quelle Medicee, Vesuviane e quelle esistenti nel territorio del comune di Bagheria. Con il volume della Giusti, le ville barocche e tardo barocche di Bagheria vengono inserite nel vasto panorama culturale …
Supporting Impact Analysis by Program Dependence Graph Based Forward Slicing
2007
Since software must evolve to meet the typically changing requirements, source code modifications can not be avoided. Impact analysis is one of the central and relatively demanding tasks of software maintenance. It is constantly needed while aiming at ensuring the correctness of the made modifications. Due to its importance and challenging nature automated support techniques are required. Theoretically, forward slicing is a very suitable technique for that purpose. Therefore, we have implemented a program dependence graph (PDG) based tool, called GRACE, for it. For example, due to the typical rewritings of Visual Basic programs there is a great need to support their impact analysis. However…
