No full textАвтор намагається з’ясувати, яку роль відіграв гетьман Павло Скоропадський у справі заснування Української академії наук та причини, що призвели до затьмарення ролі глави Української Держави в «академічному процесі». Аналізуються самооцінка Павла Скоропадського, інвективи Миколи Василенка та Володимира Вернадського щодо його ролі в заснуванні УАН, а також офіційна документація та публічні акти 1918 р. Автор статті доходить висновку, що П.Скоропадський має бути залучений до кола «батьків-засновників» УАН.The author is trying to find out which role hetman Pavlo Skoropads’kyi performed in the case of foundation of Ukrainian Academy of Sciences and the causes that led to diminishing of the part of Ukrainian state’s head in «academic process». The article analyzes Pavlo Skoropads’kyi’s self-assessment, Mykola Vasylenko’s and Volodymyr Vernads’kyi’s invectives as to his role in foundation of UAS, and official documents and public acts of 1918. The author of the article comes to the conclusion that P.Skoropads’kyi has to be enlisted to the circle of founders of UAS
Analytical Review of the Biobibliography of Pavlo Zahrebelnyi
No full textThe purpose of the article is to conduct a critical study of the bibliography of Pavlo Zahrebelnyi in the indexes contained in the collection of V. I. Vernadsky National Library of Ukraine (herein after referred to as VNLU) and available in the Internet environment, to analyze the selected bibliographic indexesusing modern methodological developments; to evaluate and provide evidence of their scientific, informational, and cultural and historical value. Methodology. The study used survey-bibliographic, analytical-critical, historical, and comparative scientific methods. Scientific novelty. For the first time, a study of the bibliography, divided into many editions in the form of indexes, was carried out; the artistic and literary orientation of Pavlo Zahrebelnyi’s works was taken into account using new theoretical and methodological principles. The article meets the current tasks of modern bibliographic studies. Conclusions. The works by Pavlo Zahrebelnyi are known outside Ukraine, have been translated into many languages of the world, and have been repeatedly filmed. Not all of them have become outstanding artistic achievements of Ukrainian prose, but all of them have been actively perceived by readers, discussed by critics, and in one way or another influenced the development of the modern literary process. The critical analysis of the indexes logically led the author of the article to the opinion that the compilation of acomplete consolidated bibliographic index is still waiting for its author. The publication of the writer’s private diaries is still ahead, and there is information on the Internet about holding scientific conferences dedicated to the work of Pavlo Zahrebelnyi and, as a result, the publication of articles in periodicals and collections
Pavlo Galagan (1853-1869) in the sources of personal origin
No full textУ статті поглиблено уявлення про родинно-генеалогічну історію сімейства Ґалаґанів у другій половині XIX ст. Автор створює «біографічний портрет» Павла Ґалаґана, останнього прямого нащадка роду, який набув високого соціального статусу на початку XVIII ст. У статті
Павло Ґалаґан охарактеризований у контексті життєдіяльності свого соціального середовища на основі інтерпретації змісту джерел особового походження (мемуари, щоденникові записи, листи тощо), створених ним самим та близькими до нього людьми.В статье расширено представление о семейно-генеалогической истории рода Галаганов, представителей украинской элиты казацко-старшинского происхождения, во второй половине XIX в. Автор создает «биографический портрет» Павла Галагана, последнего прямого потомка рода,
который приобрел высокий социальный статус в начале XVIII в. В статье Павел Галаган охарактеризован в контексте жизнедеятельности своей социальной среды на основе интерпретации содержания источников личного происхождения (мемуары, дневниковые записи, письма и т. п.), созданных им самим и близкими к нему людьми.The article explains deep understanding of the family and genealogical history of some families of Ukrainian
elite of Cossack origin in the second half of the 19th century.
Pavlo Galagan, as a personality, who is the last direct descendant of the Cossack Hetman origin who acquired
high social status at the beginning of the 18th century, remains only as a “memorial name”. Grygoriy Galagan
and Catherine Galagan (Kochubey), his parents, to commemorate his son after his premature death, often
mention him in the context of the university foundation. The author creates a “biographical portrait”
of Pavlo Galagan and interprets information about the socio-cultural life of the Galagan family, describes
the attitude of the representatives of Ukrainian elite of the 19th century to the problems of education, religion,
Ukrainian identity etc.
The article describes Pavlo Galagan’s social life in the context of the environment based on the interpretation
of the content sources of personal origin (memoirs, diaries, letters, etc.) created by him and people close to
him. The main focus is devoted to memories of Pavlo Galagan’s father and mother created for the College
“Yearbook” of P. Galagan, published by A. Stepovych in 1896, correspondence, in particular a pile of letters from
father to his son dated the fi rst half of 1860s, travel notes and P. Galagan’s diary, created upon the impressions
from the fi rst trip abroad in 1866.
The author emphasizes that Pavlo Galagan origin and ideological priorities are formed, on the one hand, upon
well-established traditions of training of young elite, on the other hand, according to the liberal-democratic
beliefs and “Ukrainophile” preferences of his parents

Deep Learning-basierte kardiovaskuläre Modellierung
No full textFluid dynamics play a vital role in understanding and treating a variety of cardiovascular diseases. Using high resolution medical-imaging data as well as modern flow simulation software, patient-specific blood flow in the heart and/or the vascular system can be calculated. From this data, clinically relevant parameters can be derived to supplement diagnosis and treatment. However, a widespread application of blood flow modelling in clinical practice remains unachieved despite numerous works detailing its potential to improve the diagnosis and treatment of various cardiovascular diseases. One obstacle for a clinical translation lies in the high computational demand of the blood flow modelling process, which is predominantly based on computational fluid dynamics (CFD). CFD simulations however require a considerable amount of computational power and runtime to provide accurate results. Applying these methods in clinical practice appears therefore unfeasible, since the required computational resources are rarely found in common healthcare facilities. As a possible solution to these practicability concerns, this work presents two artificial neural networks (ANN) which derive clinically relevant hemodynamic parameters from patient-specific geometry data. Compared to CFD, ANNs require little computational power and deliver results within seconds, thus potentially being more suited for a widespread clinical application.
The ANN-based modelling approach presented in this work focuses on two physically related cardiovascular diseases, namely coarctation of aorta (CoA) and aortic valve disease (AVD). In both diseases,an energy loss occurs due to a pathological constriction of available flow cross-section area within the aorta, potentially causing heart-failure if left untreated. As has been shown in previous studies, modelling patient-specific pressure within the pathological region can be of substantial benefit for diagnostics and treatment outcome. The ANN-based modelling approach presented here provides this information by calculating patient-specific pressure in the aorta, which is already a key parameter in clinical decision making, and wall-shear-stress (WSS) on the aortic wall. To assess the feasibility of this ANN-based modelling, the ANN-based computations were compared with CFD simulations for 37 (CoA) and 23 (AVD) test cases. Good agreement between both methods was found, however, several cases showed a substantial discrepancy. All in all, ANN-based modelling appears to be a feasible alternative to costly numerical methods, although further improvements are necessary for a clinical application.Im Bereich der kardiovaskulären Medizin trägt das Gebiet der Strömungsmechanik maßgeblich zum Verständnis und zur Therapie verschiedenster Herz-Kreislauf Erkrankungen bei. Mithilfe hochauflösender medizinischer Bildgebung und modernen Strömungssimulationsverfahren ist es sogar möglich, bei einem bestimmten Patienten die Strömung im Herzen und/oder im Gefäßsystem zu berechnen. Dadurch lassen sich wiederum klinisch relevante Informationen ableiten, die der Therapieplanung und Durchführung zugutekommen. Allerdings bleibt eine großflächige Anwendung solcher patientenspezifischer Modellierungsverfahren bisher aus, obwohl mehrere Forschungsgruppen das Potential solcher Verfahren, die klinische Diagnostik und Therapie zu verbessern, an verschiedensten Beispielen zeigen konnten. Ein Hindernis bei der Translation solcher Methoden in die Klinik ist der vergleichsweise hohe rechentechnische Aufwand. Bisher basieren fast alle Ansätze zur Modellierung patientenspezifischer Blutströmung auf numerischen Simulationsverfahren, welche hohe Anforderungen bezüglich Rechenleistung und Laufzeit stellen. Ein Einsatz solcher Methoden mit den an einem Krankenhaus üblicherweise real verfügbaren Mitteln ist daher schwierig bis unmöglich. Als mögliche Lösung für dieses Problem stellt diese Arbeit zwei künstliche neuronale Netze (engl. „artifical neural network“, kurz ANN) vor, welche klinisch relevante strömungsmechanische Parameter aus patientenspezifischen Geometriedaten berechnen. ANNs haben dabei den Vorteil, kaum nennenswerte Rechenleistung zu brauchen und Ergebnisse in wenigen Sekunden zu liefern.
Das hier entwickelte Berechnungsverfahren konzentriert sich dabei auf zwei strömungsmechanisch verwandte Herzkreislauf-Erkrankungen, nämlich Aortenisthmusstenosen (ISTA) und Aortenstenosen (AS). Bei beiden Erkrankungen entsteht ein Energieverlust aufgrund einer pathologischen Engstelle in der Aorta, welcher auf lange Sicht zu schwerer Herzinsuffizienz führen kann. Informationen über die Druckverhältnisse im betroffenen Bereich können, wie in vorherigen Arbeiten gezeigt wurde, einen substanziellen Mehrwert für die Behandlung solcher Patienten erbringen. Die hier vorgestellten ANNs berechnen dazu den patientenspezifischen Druck in der Aorta, welcher bereits jetzt nach klinischen Richtlinien zur Behandlungsentscheidung herangezogen wird, sowie die Wandschubspannungen auf der Aortenwand. Um die Nutzbarkeit der ANNs für den klinischen Gebrauch einschätzen zu können, wurden ANN-basierte Ergebnisse mit numerischen Simulationen für 37 ISTA- und 23 AS-Testfälle verglichen. Es fand sich eine gute Übereinstimmung bei der Vorhersage des Drucks und der Wandschubspannung, allerdings waren in einigen Einzelfällen hohe Abweichungen zwischen beiden Simulationsmethoden zu beobachten. Insgesamt konnte gezeigt werden, dass eine ANN-basierte Berechnung eine vielversprechende Alternative zu aufwendigen numerischen Simulationen sind, jedoch bedarf es noch einiger Verbesserungen für eine klinische Anwendung.BMBF, 13GW0208B, ArtiCardi
Female deconstruction as the main paradigm of the plot of Pavlo Arie’s play “Colours”
No full textIn the article the author investigates female deconstruction as the basic subject line of the plot of "Colours", by modern Ukrainian playwright Pavlo Arie. The researcher relies on the concepts of the metaphysics of presence (Derrida) and the sensible trancendental (Irigaray) in analyzing the female essence as materia prima, and its integration into modern cosmogony.У цій статті автор розглядає жіночий деконструкт як основу сюжету п’єси сучасного українського драматурга Павла Ар’є "Кольори". Дослідниця спирається на концепти метафізики присутності (metaphysics of presence) (за Деридою), відчутного трансцендентного (sensible trancendental) (за Ірігаре), аналізуючи жіночу сутність як першоматерію та її вписування у новітню космогонію

"State" poet: phenomenon of Pavlo Tychyna in the reception of Vasyl’ Stus
No full textThe article deals with the reception of Pavlo Tychyna by VasyT Stus in his significant work A Phenomenon of Our Time. The analysis of the work helps to build an understanding of the important aspects of Stus' conception of poet: Tychyna's destiny, his choice and the loss of talent become to be symbols of subordination of poet to the power, The author examines the reception of Tychyna in the context of Stus’ ethical principles, and also in the contexts of the "official" soviet literary studies, the reception of Tychyna in the circle of'shistdesiatnyky' ('the sixtiers’), and literary studies in the Ukrainian diaspora. The special consideration is given to the text, which was the philosophical basis for A Phenomenon of Our Time - Les Discours de Suède by Albert Camus. The author tries to analyze the impact of the existentialism philosophy on Vasyl Stus' worldview and on his conception of the creative work
