Charge transfer in dissociating iodomethane and fluoromethane molecules ionized by intense femtosecond X-ray pulses. Structural Dynamics, 3(4). doi:10.1063/1.4944344Additional Authors: Marchenko, T.;Miron, C.;Patanen, M.;Osipov, T.;Schorb, S.;Simon, M.;Swiggers, M.;Techert, S.;Ueda, K.;Bostedt, C.;Rolles, D.;Rudenko, A.Ultrafast electron transfer in dissociating iodomethane and fluoromethane molecules was studied at the Linac Coherent Light Source free-electron laser using an ultraviolet-pump, X-ray-probe scheme. The results for both molecules are discussed with respect to the nature of their UV excitation and different chemical properties. Signatures of long-distance intramolecular charge transfer are observed for both species, and a quantitative analysis of its distance dependence in iodomethane is carried out for charge states up to I21+. The reconstructed critical distances for electron transfer are in good agreement with a classical over-the-barrier model and with an earlier experiment employing a near-infrared pump pulse. © 2016 Author(s)

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets
No full textCitation: Tanyag, R. M. P., Bernando, C., Jones, C. F., Bacellar, C., Ferguson, K. R., Anielski, D., . . . Vilesov, A. F. (2015). Communication: X-ray coherent diffractive imaging by immersion in nanodroplets. Structural Dynamics, 2(5), 9. doi:10.1063/1.4933297Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction. The technique is robust, fast-converging, and yields the complex density of the immersed object. Images of xenon clusters embedded in superfluid helium droplets reveal transient configurations of quantum vortices in this fragile system. (C) 2015 Author(s).

Philosophical and Economic Manuscripts of Mykola Rudenko: Priceless Treasure was Unvalued of Descendants
No full textУ статті проаналізовано оригінальне вчення Миколи Руденка (1920–2004) про сутність зв’язку людини й суспільства з біосферою як космічним феноменом та засади їх гармонійного розвитку, який може здійсню-ватися лише за умов «прирощення енергії». На цьому у XVIII ст. наполягали французькі фізіократи; означений шлях вважали єдино прийнятним С. Подолинський, В. Вернадський, А. Сахаров та ін. На основі дослідження автор приходить до висновку щодо актуальності ідей М. Руденка для України й сучасного світу. The original teaching of Mykola Rudenko (1920−2004) is analysed in the article. He went through a difficult way of spiritual evolution: from the communist-stalinist to the communist who is looking for truth and the dissident. Our countryman paid attention to the discrepancy between the low standard of living of workers in the Soviet Union and the high cost of labor and material resources in industrial and agricultural production. He found the reason of it in violation of the fundamental principles of communication between the man, society, the biosphere, the nature of Earth and the Universe, which were the result of practical application of theoretical principles of Marxism. M. Rudenko proved that harmonious development of any modern society is possible only in case of orientation of all its spheres to “an energy increment”. The French Physiocrats insisted on this in the XVIII century; the same way is considered the only possible by S. Podolynsky, V. Vernadsky, A. Sakharov and others. The author comes to the conclusion that the relevance of the ideas of M.Rudenko for Ukraine and the modern world on the basis of the produced research
Reaching Across the Distance: An Autoethnography of Ukrainian Landscapes in the Liminal Space
No full textRussia’s full-scale invasion of Ukraine in 2022 has intensified human displacement and environmental damage. Having lost my home in Ukraine and moved to Canada, I found myself in a liminal space, disconnected from my homeland. In this posthumanist autoethnography, I explore how I could engage with the Ukrainian landscapes from afar. To answer this question, I wrote an autobiographical timeline, in which I described the most important landscapes of my life. I combined it with the stories from six conversations about home with people from my personal network. What I learnt about myself and others enabled me to describe an inanimate agency, the Eerie, that hinders my connection with the Ukrainian land. I outlined the key elements of the Eerie: ambivalent feelings toward my family, postcolonial haunting, landscape loss due to war, internalized colonialism, and voicelessness. I found ways to counter each component and engage with my home landscapes beyond distance and destruction: through a persisting emotional bond, growing love for the new places, by imagining my way into the landscape’s way of being, sharing stories about landscapes, and listening to my body. This study offers a perspective on the presence of the Eerie in the postcolonial experience of displacement and invites story-sharing about landscapes we cherish to foster relationships between people

ГЛЮТОНІМИ-СИМВОЛИ ТЕМПОРАТИВНОГО ЦИКЛУ «УКРАЇНСЬКА ВЕСНЯНА ОБРЯДОВІСТЬ»
No full textIn the article «Gluttonims-symbols of temporative cycle» Ukrainian spring folk-calendarian ceremonialism» S. Rudenko considers lingual and conceptual symbiosis of nutrition sphere nominations and sign-oriented time lines, which are the form of expressing deep world outlook ideas of Ukrainians. It is emphasized that nutritional symbols manifest common idea of the event, personifying the situation in general, and stressing he importance of background knowledge and cultural competence. The purpose of the proposed study is to examine the connection between glutonim-linguistic signs of the food picture of the world with a wide spectrum of expression plan (from word to text) and the content plan (the translation of cultural information, background, concepts, connotations, etc.) on the basis of the Ukrainian ethnolinguistic discourse, – meaningful cultural symbols, and temporatives nominating certain time intervals of spring folk-calendar rituals. The author analyzes semantics of the linguistic signs, conceptually related to the semantics of food consumption / refusal of food, which fi ll such terminals as the duration of food intake during one meal; multiplicity of food intakes during the day; intervals between individual meals; the order of food consumption within a single meal; duration of cooking; culturally preconditioned time parameters of food consumption: daily, weekly, family-ritual, calendar-ritual, church-ritual; special calendar periods, etc.У статті «Глютоніми-символи темпоративного циклу «Українська весняна народно-календарна обрядовость» С. Руденко розглядається мовний та концептуальний симбіоз номінацій харчової сфери й знакових часових відрізків, що є формою вираження глибинних світоглядних уявлень українців. Підкреслюється, що символи харчового характеру маніфестують загальну ідею події, персоніфікуючи ситуацію в цілому та підкреслюючи важливість фонових знань і культурної компетенції
Professor Myron Korduba’s Contribution Into Geographical Shevchenkiana
No full textThe article deals with most essential specificities of creative approach and major results of regional geographical studies of Taras Shevchenko, an outstanding Ukrainian poet and painter, disclosed by Myron Korduba (1876 – 1947), Professor, Warsaw University, in his T. Shevchenko as Regional Ethnographer and Archaeologist. It was accentuated that, when studying nature and local people, Taras Shevchenko preferred “a good pencil-drawn sketch from nature”; focused on specific natural phenomena, characteristic for this or that locality; put people and community, their culture and everyday life into a center of his regional geographical cognition
Alfred Barr's Chronological Concept in the Context of Creating a Potential Collection of the Ukrainian Museum of Modern Art
No full textThe purpose of the article is to verify the utilitarianism of Alfred Barr’s concept of the chronological frames of museumification of modern art for the formation of a potential collection of the Ukrainian Museum of Modern Art. Research methodology. The following methods are used: skeptical empiricism, extrapolation, deductive logic, and scientific criticism. Scientific novelty. The article is the first attempt to adapt the MoMA’s conceptual experience to solving the problem of defining the chronological frames of a potential collection of the Ukrainian Museum of Modern Art. Despite the lack of coincidence of cultural and historical contexts, A. Barr’s chronological concept can be considered as an initial hypothetical framework for the development of a temporal coordinate system for the museumification process. Formally, the process of circumscription of chronological boundaries can be presented as follows: M is the year of the beginning of museumification; R is the reference chronological point of the museum object. R = M-8. T — Barr’s “torpedo” — is the period of the object of museumification. T(x) [tail] = R-75. T(h) [head] = R+25. T = T(x) + T (h). The torpedo “movement” phase = T+25 if M+8. Conclusions. The approach using two chronological tracks is due to the fact that the “torpedo” must be in permanent motion on the way to the future. Every eight years from the beginning of museumification, the chronology of the object of museumification is pushed forward by twenty-five years. Taking into account the similarities in the work of museum institutes around the world, A. Barr’s formula is relevant to modern Ukrainian realities. Given 2022 (although the creation of the Museum of Modern Art this year is unlikely), the following chronological sequence can be proposed: 1939 – 1964 – 1989 – 2014 – 2039. Each of the above dates, except for the last one, is significant for Ukraine, Europe, and sometimes the world as a whole, and also affects artistic culture
