Toward an Expert System for Terrain Analysis.

Terrain analysis is the systematic study of image patterns relating to the origin, and composition of distinct terrain units called landforms. It takes into account and provides information about physical site factors which are used by civil engineers for evaluating the suitability of a site for a terrain related engineering application. Terrain analysis is a time consuming labor intensive process and requires a significant degree of expertise. In this dissertation, an expert system paradigm has been adopted, for developing a computational approach to terrain analysis problem solving. A methodology was developed for the representation and management of uncertain terrain knowledge. The vagueness that is inherent in the descriptions of terrain analysis terms was represented using fuzzy models. The Dempster-Shafer theory of evidence was adopted to establish hypotheses about the type of terrain based on observed evidences. A goal directed backward form of reasoning was employed for evaluating the suitability of a site for a terrain related engineering application. The reasoning strategy was formalized in production rules, and the fuzzy models of terrain terms were formalized in frames. Procedural computations were formalized in LISP code. The methodology was implemented in the Terrain Analysis eXpert (TAX) system. TAX was developed by employing the expert system shell KEE (Knowledge Engineering Environment) and the image processing package ELAS (Earth resources Laboratory Application Software). TAX was tested with a real data set consisting of a digitized color infra-red photograph and digital elevation data. The conclusions arrived at by TAX compared favorably to those reached by an expert who analyzed the same site using traditional photointerpretation techniques

Cushing's syndrome in pregnancy: a review of reported cases

Cushing’s syndrome (CS) causes hypogonadotropic hypogonadism and anovulatory infertility due to hypercortisolism, and it is very rare in pregnancy. CS in pregnancy is associated with important maternal-foetal morbidity and mortality, such as preeclampsia and premature delivery. A systematic search was conducted in the MEDLINE library to retrieve articles reporting cases of CS in pregnant women, during the period between 2010 and 2020.Thirty-five reported cases are presented focusing on the ability of diagnosis, treatment therapies, and foetal outcomes. Diagnosis of CS during pregnancy can be challenging and is often delayed, adrenal adenoma being the predominant cause. Both medical treatment and surgery aiming at restoring the cortisol balance reduce maternal and foetal complications

Implicating genes, pleiotropy, and sexual dimorphism at blood lipid loci through multi-ancestry meta-analysis

Publisher Copyright: © 2022, The Author(s).Background: Genetic variants within nearly 1000 loci are known to contribute to modulation of blood lipid levels. However, the biological pathways underlying these associations are frequently unknown, limiting understanding of these findings and hindering downstream translational efforts such as drug target discovery. Results: To expand our understanding of the underlying biological pathways and mechanisms controlling blood lipid levels, we leverage a large multi-ancestry meta-analysis (N = 1,654,960) of blood lipids to prioritize putative causal genes for 2286 lipid associations using six gene prediction approaches. Using phenome-wide association (PheWAS) scans, we identify relationships of genetically predicted lipid levels to other diseases and conditions. We confirm known pleiotropic associations with cardiovascular phenotypes and determine novel associations, notably with cholelithiasis risk. We perform sex-stratified GWAS meta-analysis of lipid levels and show that 3–5% of autosomal lipid-associated loci demonstrate sex-biased effects. Finally, we report 21 novel lipid loci identified on the X chromosome. Many of the sex-biased autosomal and X chromosome lipid loci show pleiotropic associations with sex hormones, emphasizing the role of hormone regulation in lipid metabolism. Conclusions: Taken together, our findings provide insights into the biological mechanisms through which associated variants lead to altered lipid levels and potentially cardiovascular disease risk.Peer reviewe

An analysis of the literary style of poet A. Sikelianos: the functionality of the adjective in A. Sikelianos poetry

This thesis aims at the systematic study of A. Sikelianos poetic work based on the acknowledgement that a big current of the contemporary literature theory (Russian formalism, literary semeiotic science) springs from the ancient poetic and rhetoric science (subjects of study in Aristotle’s main works).Therefore, a systematic comparative research between the ancient poetry and rhetoric and the contemporary literary theory is attempted. The main axis of the research is the functionality of the adjective. This is defined firstly by the particular importance of the adjective, according to the frequency and the joining with the other linguistic elements in the poetic composition, as a contributory factor in creating aesthetic speech, secondly by the speculation of its function in A. Sikelianos poetry.The methodological field consists firstly of the statistics of the style/speech based on the frequency of the adjective as it is shown in detailed statistic tables and graphics (included in the thesis volume), secondly of the application of style criteria-archetypes of the ancient Greek tradition as follows: Demetrius (Phalireus) «Demetrius on Style», Dionysius of Halicarnassus, «On Literary Composition» and Dionysius Loggino «Critical Essays».In the first part of the research an interpretation of the above mentioned archetypes is attempted. In the second part an analytical application of the archetypes is carried out, as speech criteria in selected works-extracts of A. Sikelianos poetry, either odd or through a combination of criteria according to the proper element for each poetic work.The application of the speech criteria defines the research frame of the thesis – An analysis of the literary style of poet A. Sikelianos. The aimed study concerns the functionality of the adjective, as a factor in creating aesthetic speech in A. Sikelianos poetry.The research founded on the one hand on the statistic analysis and its findings (tables, graphics), on the other hand on the analytical speech study - interpretation of the poet’s style, shows the following conclusions: a limited use of the adjective and a careful, judicious use in its joining with the other linguistic elements in the poetic composition. The components of the variety and the creation of a meaningful adjective constitute a combination of factors which contribute, in a morphological, syntactic and semantic level, to the creation of aesthetic speech in A. Sikelianos poetry.Η εκπόνηση της Διατριβής αποσκοπεί στη συστηματική μελέτη της «ποιητικής» του έργου του Άγγ. Σικελιανού, θεμελιωμένη στην αποδοχή ότι ένα μεγάλο ρεύμα της σύγχρονης θεωρίας της λογοτεχνίας (ρωσικός φορμαλισμός, φιλολογική Σημειωτική επιστήμη), έλκει τις θεωρητικές αφετηρίες του στην αρχαία «ποιητική» και «ρητορική» τέχνη, (αντικείμενα πραγμάτευσης των κεφαλαιωδών έργων του Αριστοτέλους: I. «Περί Ποιητικής» και II. «Ρητορική Τέχνη».Επομένως επιχειρείται συστηματική συγκριτική έρευνα ανάμεσα στην αρχαία ποιητική και ρητορική και στη σύγχρονη λογοτεχνική θεωρία.

Mining Transition and Hydropower Energy in Greece—Sustainable Governance of Water Resources Management in a Post-Lignite Era: The Case of Western Macedonia, Greece

The present study explores the process of Greece’s current decarbonisation transition and its energy policy regarding the country’s two coal-mining areas. Using the Region of Western Macedonia as a case study, we aimed at providing a holistic approach—as until now only few attempts have been made to systematise the ‘Just Transition Plans’ in European Union (EU)—for raising awareness on issues related to water resource management in post-lignite areas and analysing the use of hydropower in Greece. Our research draws on a flexible method approach, serving as a tool to identify gaps in current knowledge and practices, based on two stages—first the analysis of existing literature, reviews, and sources from government’s core strategies, as well as policy and decision-making papers, and then formulating research questions by synthesising relevant data. In Greece, both ‘Just Transition Development Plan of Lignite Areas’ and hydropower production practices overlook water resources management. By summarising our findings and identifying gaps that remain in current approaches, this work indicates future directions by suggesting processes necessary for addressing the complex issue of adoption of sustainable water resources management measures in post-lignite eras in accordance with EU’s water policy

Sympathetic Nerve Injury in Thyroid Cancer

The double innervation of the thyroid comes from the sympathetic and parasympathetic nervous system. Injury rates during surgery are at 30% but can be minimized by upwardly preparing the thyroid vessels at the level of thyroid capsule. Several factors have been accused of increasing the risk of injury including age and tumor size. Our aim was to investigate of there is indeed any possible correlations between these factors and a possible increase in injury rates following thyroidectomy. Seven studies were included in the meta-analysis. Statistical correlation was observed for a positive relationship between injury of the sympathetic nerve and thyroid malignancy surgery (p < 0.001; I2 = 74%) No statistical correlations were observed for a negative or positive relationship between injury of the sympathetic nerve and tumor size. There was also no statistically significant value observed for the correlation of the patients’ age with the risk of sympathetic nerve injury (p = 0.388). Lack of significant correlation reported could be due to the small number of studies and great heterogeneity between them

Diagnosis, Management and Prescription Practices of Adrenaline in Children with Food-Induced Anaphylaxis: Audit in a Specialized Pediatric Allergy Department

In the era of evidence-based medicine, physicians worldwide should abide by universally approved practices and healthcare units should seek quality control and operational improvement. This audit evaluates the degree of compliance with the European Academy of Allergy and Clinical Immunology guidelines for the diagnosis and treatment of anaphylaxis in a pediatric Allergy Department. Medical records of 248 children with food-induced allergic reactions who presented both on emergency and outpatient basis were reviewed. Data were also collected from the e-prescription database and anaphylaxis severity was graded according to Sampson&rsquo;s criteria. An accuracy metric was used to calculate the consistency rate. Anaphylaxis was documented in 188/423 allergic reactions. The degree of agreement for the classification of the reactions as anaphylactic was 88.3%, while the respective rate for non-anaphylactic was 58.7%. In the anaphylactic cases, adrenaline was prescribed in 84.8%, while the respective rates for other drugs were: antihistamines: 27.6%; corticosteroids: 26.1%; inhaled &beta;2-agonists: 11.8%. This study, through the example of pediatric food-induced anaphylaxis, underlines the significance of compliance to guidelines, organized documentation in healthcare units using specially formulated medical history forms and continuous medical stuff training. Thus, diagnosis and treatment practices can be improved for the benefit of patients
