TL;DR: This study provides important and interesting data that could help clinicians and surgeons as well as oral and maxillofacial pathologists with the diagnosis and management of these lesions.
Abstract: Background The aim of this study was to integrate the available data published on calcifying odontogenic cyst (COC), dentinogenic ghost cell tumor (DGCT), and ghost cell odontogenic carcinomas (GCOCs) into a comprehensive analysis of their clinicoradiological features, treatment, and recurrence. Materials and methods An electronic search with no publication date restriction was undertaken in October 2017 in the following databases: PubMed, Medline Ovid, Web of Science, and Scopus. Eligibility criteria included publications containing enough clinical, radiological, and histopathological information to confirm a definite diagnosis of these lesions. Data were evaluated descriptively. Results The literature review indicated a total of 234 publications reporting 367 COCs, 55 DGCTs and 44 GCOCs. These lesions have a predilection for Asian males. COCs mainly affect the mandible and patients in the second decade of life, DGCTs mostly affect the mandible and patients in the fourth decade of life, and GCOCs mostly affect the maxilla and patients in the fifth decade of life. Conclusion Conservative surgery was the most common therapy for COCs and DGCTs, while radical surgery was most common for GCOCs. This study provides important and interesting data that could help clinicians and surgeons as well as oral and maxillofacial pathologists with the diagnosis and management of these lesions.

TL;DR: The short version of the Depression Anxiety Stress Scale-21 showed excellent values of reliability, and strong internal consistency, and the two-factor model with condensation of the constructs anxiety and stress in a single factor was the most acceptable for the adolescent population.
Abstract: Objetivo Avaliar a reprodutibilidade interdias, a concordância e a validade do construto da versao reduzida da Depression Anxiety Stress Scale-21 aplicada a adolescentes. Metodo A amostra foi composta por adolescentes de ambos os sexos, com idades entre 10 e 19 anos, recrutados de escolas e centros esportivos. A validade de construto foi realizada por analise fatorial exploratoria, e a confiabilidade foi calculada para cada construto, por meio de coeficiente de correlacao intraclasse, erro padrao de medida e mudanca minima detectavel. Resultados A analise fatorial combinando os itens correspondentes a ansiedade e estresse em um unico fator, e depressao em um segundo fator apresentou melhor adequacao de todos os 21 itens, com cargas fatoriais mais altas em seus respectivos construtos. Os valores de reprodutibilidade para a depressao foram coeficiente de correlacao intraclasse com 0,86, erros padrao de medida com 0,80 e mudanca minima detectavel com 2,22 e, para a ansiedade/estresse, foram coeficiente de correlacao intraclasse com 0,82, erro padrao de medida com 1,80 e mudanca minima detectavel com 4,99. Conclusao A versao reduzida da Depression Anxiety Stress Scale-21 apresentou excelentes valores de confiabilidade e tambem uma forte consistencia interna. O modelo de dois fatores com a condensacao dos construtos ansiedade e estresse em um unico fator foi o mais aceitavel para a populacao adolescente.

TL;DR: The results show that 40% of reported faults were due to the lack of awareness among base code and aspects, which contradicts the common intuition stating that the use of pointcut languages is the main source of faults in AOP.
Abstract: This paper presents the results of an exploratory study on the fault-proneness of aspect-oriented programs. We analysed the faults collected from three evolving aspect-oriented systems, all from different application domains. The analysis develops from two different angles. Firstly, we measured the impact of the obliviousness property on the fault-proneness of the evaluated systems. The results show that 40% of reported faults were due to the lack of awareness among base code and aspects. The second analysis regarded the fault-proneness of the main aspect-oriented programming (AOP) mechanisms, namely pointcuts, advices and intertype declarations. The results indicate that these mechanisms present similar fault-proneness when we consider both the overall system and concern-specific implementations. Our findings are reinforced by means of statistical tests. In general, this result contradicts the common intuition stating that the use of pointcut languages is the main source of faults in AOP.

07 Nov 2011TL;DR: A mechanism for functional TC selection which considers two objectives simultaneously: maximize requirements' coverage while minimizing cost in terms of TC execution effort and two multi-objective versions of PSO are implemented.
Abstract: Although software testing is a central task in the software lifecycle, it is sometimes neglected due to its high costs. Tools to automate the testing process minor its costs, however they generate large test suites with redundant Test Cases (TC). Automatic TC Selection aims to reduce a test suite based on some selection criterion. This process can be treated as an optimization problem, aiming to find a subset of TCs which optimizes one or more objective functions (i.e., selection criteria). The majority of search-based works focus on single-objective selection. In this light, we developed a mechanism for functional TC selection which considers two objectives simultaneously: maximize requirements' coverage while minimizing cost in terms of TC execution effort. This mechanism was implemented as a multi-objective optimization process based on Particle Swarm Optimization (PSO). We implemented two multi-objective versions of PSO (BMOPSO and BMOPSO-CDR). The experiments were performed on two real test suites, revealing very satisfactory results (attesting the feasibility of the proposed approach). We highlight that execution effort is an important aspect in the testing process, and it has not been used in a multi-objective way together with requirements coverage for functional TC selection.
