On the Use of Supervised Learning Method for Authorship Attribution
In this paper we investigate the use of a supervised learning method for the authorship attribution that is for the identification of the author of a text. We suggest a new, simple and efficient method, which is merely based on counting the number of repetitions of each alphabetic letter in the text, instead of using the traditional classification properties; such as the contents of the text and style of the author; which falls into four feature categories: lexical, syntactic, structural, and content-specific. Furthermore, we apply a spherical classification method. We apply the proposed technique to the work of two Italian writers, Dante Alighieri and Brunetto Latini. With almost high reliability, the spherical classifier proved its ability to discriminate between the selected authors. Finally the results are compared with those obtained by means of a standard Support Vector Machine classifier
Influence of nanoparticles addition on the fatigue failure behavior of metal matrix composites : Comprehensive review
AbstractLight-weight, high-strength metal matrix composites (MMCs) have been gaining prominence in various industrial applications in which the materials are exposed to static and dynamic loading conditions. Unfortunately, micron-sized MMCs frequently encounter challenges such as particle breakage and debonding at the reinforcement-matrix interface, resulting in premature failure due to the decline in their mechanical properties, making them impractical to be utilized in some crucial applications. On the other hand, metal matrix nanocomposites (MMNCs) have been proven to improve strength, ductility, and fracture toughness characteristics, which are greatly beneficial in various industrial applications such as automotive, aerospace structures, and biomaterials. This review provides a comprehensive insight into the effect of nanoparticle addition on the fatigue performance of metals and alloys. Firstly, special attention has been given to the factors influencing the fatigue life of MMNCs. Secondly, the effect of nanoparticle incorporation on the fatigue performance of common metal matrixes, including aluminum, magnesium, titanium, and steel alloys, is reviewed in detail. Finally, a summary of this review and the future aspects related to the behavior of metals with nanoparticles at cyclic loading is provided.Abstract

Surface nanocratering by localized plasma expansion induced by slow highly charged ions
Ion beam technology provides a powerful means for surface modification and nanostructuring of materials. In this work, slow highly charged xenon ions were used to fabricate well-defined nanopits in thin polymethyl methacrylate (PMMA) films. The pit surface density scales linearly with the applied ion fluence, demonstrating that each structure originates from a single ion impact. The formation of these nanopits is interpreted within a plasma expansion framework, in which the potential energy of an individual highly charged ion creates a transient, localized plasma within a nanometric surface region. The subsequent plasma expansion ejects material and produces a shallow surface depression. Numerical solutions of the hydrodynamic equations for the plasma components yield expansion parameters that agree with the experimentally observed pit dimensions and aspect ratios, confirming the plausibility of the proposed mechanism
Phenolic metabolites, biological activities, and isolated compounds of Terminalia muelleri extract
© 2017 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.[Context]: Terminalia muelleri Benth. (Combretaceae), is rich with phenolics that have antioxidant and cytotoxic activities. No screening studies were published before on T. muelleri.[Objective]: The study focused on isolation and identification of secondary metabolites from aqueous methanol leaf extract of T. muelleri and evaluation of its biological activities.[Materials and methods]: The n-butanol extract was chromatographed on polyamide 6, and eluted with H2O/MeOH mixtures of decreasing polarity, then separated by different chromatographic tools that yielded 10 phenolic compounds. The antioxidant activity of the extract was evaluated by investigating its total phenolic and flavonoid content and DPPH scavenging effectiveness. The extract and the two acylated flavones were evaluated for their anticancer activity towards MCF-7 and PC3 cancer cell lines. Molecular docking study of the acylated flavones was performed against topoisomerase enzyme.[Results and discussion]: Two acylated flavonoids, apigenin-8-C-(2″-O-galloyl) glucoside 1 and luteolin-8-C-(2″-O-galloyl) glucoside 2, were isolated and identified for the second time in nature, with eight tannins (3–10), from the leaves of T. muelleri. The extract and compound 10 showed the most significant antioxidant activity (IC50 = 3.55 and 6.34 μg/mL), respectively. The total extract and compound 2 demonstrated cytotoxic effect against MCF-7 with IC50 = 29.7 and 45.2 μg/mL respectively, while compound 1 showed cytotoxic effect against PC3 (IC50 = 40.8 μg/mL). The docking study of compounds 1 and 2 confirmed unique binding mode in the active site of human DNA topoisomerase enzyme.[Conclusions]: Terminalia muelleri is a promising medicinal plant as it possesses high antioxidant activity and moderate cytotoxic activity against MCF-7.Peer Reviewe

Expert consensuses have defined a modular pathway to accredit surgeons. This study aimed to address the lack of a formal, pre-clinical core robotic skills, proficiency-based accreditation curriculum in the UK. Novice robotic participants underwent a four-day pre-clinical core robotic skills curriculum incorporating multimodal assessment. Modifiable-Global Evaluative Assessment of Robotic Skills (M-GEARS), VR-automated performance metrics (APMs) and Objective Clinical Human Reliability Analysis (OCHRA) error methodology assessed performance at the beginning and end of training. Messick's validity concept and a curriculum evaluation model were utilised. Feedback was collated. Proficiency-based progression, benchmarking, tool validity and reliability was assessed through comparative and correlational statistical methods. Forty-seven participants were recruited. Objective assessment of VR and dry models across M-GEARS, APMs and OCHRA demonstrated significant improvements in technical skill (p < 0.001). Concurrent validity between assessment tools demonstrated strong correlation in dry and VR tasks (r = 0.64-0.92, p < 0.001). OCHRA Inter-rater reliability was excellent (r = 0.93, p < 0.001 and 81% matched error events). A benchmark was established with M-GEARS and for the curriculum at 80%. Thirty (63.82%) participants passed. Feedback was 5/5 stars on average, with 100% recommendation. Curriculum evaluation fulfilled all five domains of Messick's validity. Core robotic surgical skills training can be objectively evaluated and benchmarked to provide accreditation in basic robotic skills. A strategy is necessary to enrol standardised curricula into national surgical training at an early stage to ensure patient safety
Mapping breast cancer journal publications in conflict settings in the MENA region:a scoping review
Background: Breast cancer is a major cause of cancer-related morbidity and mortality among women in the the Middle East and North Africa (MENA) region. Conflict and political instability in the region may affect medical research output, including that on breast cancer. This scoping review aims to systematically identify and map breast cancer publications across different stages of the cancer care pathway and across conflict-affected countries within the MENA region. The findings of this work will highlight the impact of conflict on cancer research that could be mitigated with the proper contextualised capacity strengthening intervention. Methods: We followed the PRISMA-Scr methodology. We searched for peer-reviewed publications on topics related to breast cancer in 11 databases: Medline, PubMed, EMBASE, Web of Science, PROQUEST, CINAHL, Global Index Medicus, Arab World Searches Complete, Popline, Scopus and Google Scholar using both controlled vocabulary and keywords. Publication abstracts and full-text versions were screened for duplicates and included in our study based on pre-specified eligibility criteria: focused on breast cancer, related to the specific country of analysis and human or health system studies. We used a structured data extraction form to extract information related to the article, its methodology and the cancer care pathway being studied. Results: A total of 19,215 citations were retrieved from our search. After removing duplicates, a total of 8,622 articles remained. Title and abstract screening retained 1,613 articles. Publications with first author affiliations to Turkey were consistently the highest across all categories of the cancer care pathway. Trends show an increase in articles from Lebanon, Jordan and Palestine after 2015. Early exploratory and epidemiological studies represented the majority of breast cancer research, followed by policy and implementation research and lastly experimental research. Most research conducted followed an observational study design. Important gaps were identified in the research output related to advanced breast cancer and palliative care (Libya, Syria and Yemen), mental health (Libya), and knowledge and education of breast cancer (Libya and Syria). Conclusion: This scoping review has identified key areas in breast cancer research that lack significant research activity in conflict MENA settings. These areas, including but are not limited to palliative care, mental health, and education, can be prioritised and developed through regional collaboration and contextualised capacity strengthening initiatives.</p
SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues
Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types. © 2021 The Author(s

Biallelic MED27 variants lead to variable ponto-cerebello-lental degeneration with movement disorders
MED27 is a subunit of the Mediator multiprotein complex, which is involved in transcriptional regulation. Biallelic MED27 variants have recently been suggested to be responsible for an autosomal recessive neurodevelopmental disorder with spasticity, cataracts, and cerebellar hypoplasia. We further delineate the clinical phenotype of MED27-related disease by characterizing the clinical and radiological features of 57 affected individuals from 30 unrelated families with biallelic MED27 variants. Utilizing exome sequencing and extensive international genetic data sharing, 39 unpublished affected individuals from 18 independent families with biallelic missense variants in MED27 have been identified (29 females, mean age at last follow-up 17±12.4 years, range 0.1-45). Follow-up and hitherto unreported clinical features were obtained from the published 12 families. Brain MRI scans from 34 cases were reviewed. MED27-related disease manifests as a broad phenotypic continuum ranging from developmental and epileptic-dyskinestic encephalopathy to variable neurodevelopmental disorder with movement abnormalities. It is characterised by mild to profound global developmental delay/intellectual disability (100%), bilateral cataracts (89%), infantile hypotonia (74%), microcephaly (62%), gait ataxia (63%), dystonia (61%), variably combined with epilepsy (50%), limb spasticity (51%), facial dysmorphism (38%), and death before reaching adulthood (16%). Brain MRI revealed cerebellar atrophy (100%), white matter volume loss (76.4%), pontine hypoplasia (47.2%), and basal ganglia atrophy with signal alterations (44.4%). Previously unreported 39 affected individuals had seven homozygous pathogenic missense MED27 variants, five of which were recurrent. An emerging genotype-phenotype correlation was observed. This study provides a comprehensive clinical-radiological description of MED27-related disease, establishes genotype-phenotype and clinical-radiological correlations, and suggests a differential diagnosis with syndromes of cerebello-lental neurodegeneration and other subtypes of "neuro-MEDopathies".</p
