Mariya Halych and the members of “Lanka” (“The Link”)
Стаття присвячена Марії Галич – єдиній жінці з літературної організації “Ланка” (із 1926 р. МАРС). Подається її біографія та аналіз художніх творів, написаних протягом 20-х – 60-х років ХХ ст. Із залишених нею автобіографій, спогадів про Б. Антоненка-Давидовича, Г. Косинку, Є. Плужника та листів до літературознавця В. Півторадні вимальовується яскрава картина літературно-мистецького життя 1920-х – поч. 1930-х років та виринає чимало невідомих подробиць про “Ланку” та ланківців.The article is dedicated Mariya Halych who was the only female member of “Lanka” literary association (after 1926 renamed “Mars”). The author gives an account on the artist’s biography and reviews her literary texts written between the 20s and the 60s. Mariya Halych’s autobiographies, her reminiscences of B. Antonenko-Davydovych, H. Kosynka, Ye. Pluzhnyk as well as letters to a well-known literary critic V. Pivtoradnia complete the vivid picture of literary and artistic environment in the 1920s and in the fi rst half of the 1930s. Such a picture contains a whole bunch of previously unknown details concerning the everyday life of “Lanka” and its members
Eigenfrequencies of the randomly pinned drum and conductivity of graphene
Graphene is a convenient material for nanomechanical applications since high-frequency oscillations are easily accessible. In this article, we consider graphene on a rough substrate attached to imperfections at random locations. We explore the statistics of low-lying phonon modes, which exert most influence on the conductivity of graphene. Our numerics suggest the hypothesis that the nearest-neighbor spacings of low-lying eigenfrequencies have the Wigner-Dyson probability distribution after averaging over the random configurations of disorder. Due to interaction of electrons with the oscillations of the membrane, an electron can be transferred to higher or lower energies, which is a manifestation of the phonon-assisted Tien-Gordon effect. The Tien-Gordon effect suppresses the conductivity of graphene. In the regime of low Fermi energies and small sizes of the sample an increase of conductivity is observed which we refer to as Klein tunneling and electron-hole pair creation. Eventually, when the increase of the transmission becomes too prominent, the pair creation changes the ground state of the system, signalizing the limit of applicability of the single-particle Dirac equation used in this article.QN/Quantum NanoscienceApplied Science
The mother’s image in the novel of mariya matios "mothers"
Буряк О. Ф. Образ матері в романі Марії Матіос «МАМИ́» / Олена Федорівна Буряк // Закарпатські філологічні студії. - Випуск 31. - 2023. - С. 195–199. URL:https://doi.org/10.32782/tps2663-4880/2023.31.33(ua) У статті осягається художня специфіка образу матері в новому романі Маріїі Матіос «Мами́ » (2023), якому авторка дає жанровизначення «драма на шість дій», що увиразнює ідейно-тематичні домінанти, пафос твору.
Образи жінок у цьому романі збагачують авторську галерею драматичних образів матерів в інших творах письменниці («Мама Маріца – дружина Христофора Колумба», «Солодка Даруся», «Майже ніколи не навпаки», новели
зі збірки «Нація»). Ключова проблема жіночого буття «мати і дитина» осмислюється авторкою у тісному взаємозв’язку з іншими проблемами: ставлення суспільства до матері, суспільний статус матері загиблого на війні сина, проблема самотності, сенсу життя. Проаналізовано наскрізний психологічний сюжет «драми на шість дій» – переживання матір’ю смерті своєї дитини: зображено особисті апокаліпсиси у свідомості п’яти героїнь, кожній із яких присвячений окремий розділ роману: «Мама Марія» (Україна. Тепер уже завжди), «Мама Веронця» (Україна. 2015), «Мама Михайлина» (Україна. В часі і між 1953 і 2015 роками), «Мама Сидонія» (Україна), «Мама Мамая». Письменниця глибинно осягає вияви колективного жіночого, материнського свідомого і підсвідомого, нюансово відтворюючи спектр почуттів, емоцій, станів жінки. Завершальний емоційний акорд у творі – так звана шоста дія, розміщена після прозової частини тексту, «Пієта», в якій образ матері підноситься до біблійного рівня через алюзію продуковану заголовком. Для відтворення інтимних, сокровенних думок, почуттів жінки авторка використовує різні форми внутрішнього мовлення: монолог, діалог, уявний діалог. У романі «Мами́» втілено в драматичному ключі «вічний» мотив безмежної любові матері до дитини. Актуальність твору увиразнюється зображенням сучасного історичного контексту – АТО, сучасна російсько-українська війна, але насамперед – емоційною суголосністю з почуттями й переживаннями сучасних матерів.
(en) The article comprehends the artistic specificity of the mother’s image in Mariya Matios' new novel "Mothers" (2023), to which the author gives the genre definition "drama in six acts", which emphasizes the ideological and thematic
dominants, the pathos of the work. The women’s images in this novel enrich the author's gallery of dramatic images of mothers in other works of the writer ("Mother Marica, the Wife of Chrystopher Columbus", "Sweet Darusya", "Almost Never the Other Way Around", short stories from the collection "Nation"). The key problem of a woman's existence "mother and child" is understood by the author in close relationship with other problems: society's attitude towards the
mother, the social status of the mother of a son killed in the war, the problem of loneliness, the meaning of life. The end-to-end psychological plot of the "drama in six acts" – the mother's experience of the death of her child – is analyzed: the personal apocalypses in the minds of five heroines are depicted, each of which is dedicated to a separate chapter of the novel: "Mother Mariya" (Ukraine. Now and Already Forever), " Mother Verontsya" (Ukraine. 2015), "Mother Mykhailyna" (Ukraine. In time and between 1953 and 2015), "Mother Sydoniya" (Ukraine), "Mother Mamaya". The writer deeply understands the manifestations of the collective femininity, maternal consciousness
and subconscious, nuancedly recreating the spectrum of feelings, emotions, states of a woman. The final emotional chord in the work is the so-called sixth act, placed after the prose part of the text, "Piyeta", in which the mother's image is raised to the biblical level through the allusion produced by the title. To reproduce the intimate, secret thoughts and feelings of a woman, the author uses various forms of internal speech: monologue, dialogue, imaginary dialogue.
To reproduce the intimate, secret thoughts and woman's feelings, the author uses various forms of internal speech: monologue, dialogue, imaginary dialogue. In the novel "Mothers" the "eternal" motif of a mother's boundless love for her
child is embodied in a dramatic way. The relevance of the work is expressed by the depiction of the modern historical context – the ATO, the modern Russian-Ukrainian war, but above all – by its emotional resonance with the feelings and experiences of modern mothers

Design and implimentation of a supervisory safety controller for a 3DOF helicopter
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2004.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 79-80).This research effort presents the design and implementation of a supervisory controller for a 3DOF helicopter. This safety critical system is used in undergraduate laboratories in the Department of Aeronautics and Astronautics at MIT. There already exists a framework for designing a supervisory safety controller for motions about one axis. It is based on an analytical description of the safety region in state space. However, this framework cannot be easily extended to more complicated systems such as a 3DOF helicopter. In this thesis we present a different approach which uses a real-time simulation of linearized plant dynamics with a feedback law to ensure the system's safety. We describe the development of the system model, the design and implementation of the supervisory safety controller, integration of the safety controller as part of a remote laboratory and its evaluation based on its performance during laboratory exercises.by Mariya A.

Understanding the rich world of outfits: a study of fashion compatibility, latent style, and outfit behavior
Many computer vision applications in the fashion domain require solving tasks where complex relationships between images, such as the notion of item compatibility, are being learned. We take a metric learning approach to representing compatibility between pairs of items. First, we introduce a model that learns compatibility relationships in dedicated embedding subspaces dependent on item type, which results in significant gains on established fashion compatibility prediction tasks. Second, we present a method for learning a richer notion of compatibility across multiple compatibility conditions whose contributions are learned as a latent variable, which provides better performance on established tasks while requiring fewer embedding subspaces to be learned. Third, we make the first published attempt at diagnosing the salient features of a pair of items that make them compatible, and linking them to human-interpretable concepts. Finally, we demonstrate that our representation of outfits enables diverse, novel, and practically-useful visual search queries for the fashion domain, and results in semantically-meaningful style summaries with several directions for future work.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-08-01The student, Mariya Vasileva, accepted the attached license on 2020-07-17 at 16:21.The student, Mariya Vasileva, submitted this Dissertation for approval on 2020-07-17 at 16:57.This Dissertation was approved for publication on 2020-07-22 at 16:02.DSpace SAF Submission Ingestion Package generated from Vireo submission #15686 on 2020-10-02 at 15:51:30Made available in DSpace on 2020-10-07T22:50:04Z (GMT).

Annunciation Day and the Mother of God in the ecclesiastical tradition and in the poem “Mariya” by Taras Shevchenko
Статтю присвячено одному з найбільш проблематичних для наукового аналізу творів Т. Шевченка – поемі “Марія”. Мотивація твору в розумінні авторки статті розкривається у двох основних контекстах: містичному й соціальному. Аналізується адекватність постатей євангельського тексту та образів поеми Т. Шевченка. Поет використовує аналогію як засіб для показу переходу від свідомості психологічного до свідомості духовного. Виявляється метафізика поетичної думки самого Шевченка та метафізика мислення головних героїв твору.This article is devoted to one of the most subtle works by T.Shevchenko, that is, to his poem “Mariya” (“Mary”). The author of the paper explores the mystical and social background of the work, concentrating on the interrelation between the evangelic fi gures and the characters in T.Shevchenko’s poem. She thus argues that the poet uses the analogy as a means of transition from the psychological to the spiritual notion of consciousness. This, in its turn, casts light upon the metaphysics of thinking, both of Shevchenko himself and of the main characters of his text
Essays in applied microeconomics
In this dissertation, I explore three important topics in environmental, urban, and labor economics.
In Chapter 1, I quantify the long-term consequences of oil and gas extraction. Pennsylvania has a long history of oil and gas extraction. When the production period ends, many wells are left behind and some remain unplugged. Unplugged wells impose serious environmental costs, including explosion hazards and risk of water, atmosphere, and soil contamination. This paper quantifies these costs by estimating the effect of unplugged wells on housing prices. I use rich data on oil and gas drilling, housing market transactions, and lease agreements to conduct difference-in-differences and instrumental variable analyses. I show that well abandonment reduces house prices. Old wells, left behind by oil and gas operators, affect house prices more than active, producing ones. However, this depreciation is reversible: if well site clean-up is completed, house prices recover almost entirely. I show that the benefits of proper well plugging are larger than the costs. This motivates environmental policies aimed at creating incentives for oil and gas producers to plug wells. These policies may include higher bankruptcy insurance requirements or environmental taxes.
Chapter 2 examines whether amenities affect the location of immigrants within the United States. Immigrants to the United States live disproportionately in metropolitan areas where nominal wages are high, but real wages are low. This sorting behavior may be due to preferences toward certain quality-of-life amenities. Relative to U.S.-born inter-state migrants, immigrants accept lower real wages to locate in cities that are coastal, larger, and offer deeper immigrant networks. They sort towards cities that are hillier and also larger and networked. Immigrants come more from coastal, cloudy, and safer countries – conditional on income and distance. They choose cities that resemble their origin in terms of winter temperature, safety, and coastal proximity.
Chapter 3 studies the impact of Secure Communities (SC)—a large U.S. immigration enforcement program—on the native earnings and wage distributions. Previous studies found that SC activation reduces the labor supply of likely undocumented immigrants by about 7% (East et al., 2020). Using unconditional quantile regression (UQR), I find the disproportionate impact of this policy on native workers across the earnings distribution. SC adoption reduces hourly wages for natives, especially for non-Hispanic workers below the median. However, this effect is at least in part mechanical—more workers take lower-paying jobs vacated by undocumented immigrants. At the same time, earnings increase at the bottom of the distribution. These results are likely driven by increased employment and suggest substitutability between lower-skilled natives and undocumented immigrants. Earnings at the middle and at the top of the distribution moderately decrease, suggesting complementarities between undocumented and higher-skilled native workers.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-05-01The student, Mariya Shappo, accepted the attached license on 2021-04-16 at 23:14.The student, Mariya Shappo, submitted this Dissertation for approval on 2021-04-16 at 23:15.This Dissertation was approved for publication on 2021-04-19 at 11:41.DSpace SAF Submission Ingestion Package generated from Vireo submission #16380 on 2021-09-16 at 20:10:24Made available in DSpace on 2021-09-17T04:04:29Z (GMT).

Representing Equivalence Problems for Combinatorial Objects
Methods for representing equivalence problems of various combinatorial objects
as graphs or binary matrices are considered. Such representations can be used
for isomorphism testing in classification or generation algorithms.
Often it is easier to consider a graph or a binary matrix isomorphism problem
than to implement heavy algorithms depending especially on particular combinatorial
objects. Moreover, there already exist well tested algorithms for the graph isomorphism
problem (nauty) and the binary matrix isomorphism problem as well (Q-Extension).
