Local subspace identification of distributed homogeneous systems with general interconnection patterns
No full textThis paper studies the local identification of large-scale homogeneous systemswith general network topologies. The considered local system identification problem involves unmeasurable signals between neighboring subsystems. Compared with our previous work in Yu et al. (2014) which solves the local identification of 1D homogeneous systems, the main challenge of this work is how to deal with the general network topology. To overcome this problem, we first decompose the interested local system into separate subsystems using some state, input and output transform, namely the spatially lifted local system has block diagonal system matrices.We subsequently estimate the Markov parameters of the local system by solving a nuclear norm regularized optimization problem. To realize the state-space system model from the estimated Markov parameters, another nuclear norm regularized optimization problem is provided by taking into account of the inherent dependence of a redundant parameter vector. Finally, the overall identification procedure is summarized.Accepted Author ManuscriptTeam Michel Verhaege
Saratov’s plot in Yu. N. Chumakov’s letters
No full textThe article discusses the place of Saratov-based plot in Yu. N. Chumakov’s letters addressed to the author of the article. The subject of discussion in the correspondence is the defense of Yu. N. Chumakov’s dissertation at Saratov University in 1970 and its role in his scientifi c biography. The defense of the dissertation with Yu. M. Lotman as the fi rst opponent became the key event of the Saratov plot and its climax. Having singled out fragments from the correspondence related to the plot of Saratov, the author seeks to explain the direction of the ensuing epistolary dialogue, why the defense of the dissertation was perceived by Yu. N. Chumakov as a more than signifi cant event for him, especially in the context of his dramatic biography. The author proves that the defense was an explosion of the linear sequence of the text of life, which dramatically changed the fate of the scientist. The desire to talk in detail about the defense, to fi nd out what impression it made, and to look at what was happening on that memorable day for him through the eyes of the addressee of the letter, betrayed the desire to read and interpret his fate again and again. Particular attention is paid in the correspondence to the personalities of such outstanding philologists, professors of Saratov University as A. P. Skaftymov and E. I. Pokusaev. Yu. N. Chumakov was not A. P. Skaftymov’s student and was not familiar with him, but specifi cally noted the acquisition and subsequent development of the principles of a scientifi c approach to the work, set out in his theoretical article in 1923. About the personality of E. I. Pokusaev, his supervisor, and the history of the relationship with him, Yu. N. Chumakov wrote in great detail. Having told about the role of E. I. Pokusaev, who supported the dissertation at the defense, and having outlined his complex, large and humanly attractive personality, Yu.N. Chumakov completes the plot of Saratov, which was very meaningful for him, primarily for self-understanding of his scientifi c path

Liquid democracy: a comparative study of digital urban democracy
No full textIn Liquid Democracy, author Yu-Shan Tseng offers a bold new framework for understanding democracy as a dynamic, fluid process. Challenging the idea that AI and digital tools are inherently anti-democratic, this innovative volume bridges theory and practice to investigate various “liquid conditions,” a novel concept capturing how political action flows and transforms like water within the intersections of urban spaces and digital technologies.Through an in-depth comparative study of three groundbreaking digital democracy platforms—Decide Madrid in Madrid, OmaStadi in Helsinki, and vTaiwan in Taipei—Tseng explores how digital platforms can foster participatory governance, pluralism, and alternative democratic futures. In-depth chapters critically examine the interactions between humans, algorithms, and urban systems, revealing how digital tools reconfigure the boundaries of political participation, decision-making, and collective action. Throughout the text, Tseng offers fresh insights into how democracy emerges under contingent conditions shaped by technology and geography.Drawing from years of ethnographic fieldwork, Liquid Democracy is essential reading for master’s and PhD students in geography, political science, and urban studies, as well as scholars, practitioners, and policymakers interested in digital governance, smart cities, civic technology, and algorithmic politics
Key Plots of Legal Thinking. Book Review: Permyakov Yu. E. Contemporary Philosophy of Law: An Overview of the Main Problems
No full textThe review provides a detailed account of the textbook by Yuri Evgenievich Permyakov “Contemporary Philosophy of Law: An Overview of the Main Problems” (St. Petersburg: Lan’, 2023). The author’s contribution to clarifying the province and structure of the discipline, its role in the formation of legal thinking is emphasized. The originality of the proposed reading from the point of view of the metaphysics of law of such categories as agent, ought, judicial authority, subjective right, obligation is noted. The author brings important emphases to the discussion of controversial issues of the boundaries of the law as well as of scientific status and tasks of jurisprudence. Yu. E. Permyakov considers the main task of jurisprudence in general and legal science in particular to be the drawing a line between law and non-law. In view of this task, he examines issues of the legal force of normative and law enforcement acts and of a dispute as an immanent condition of legal life. The author’s proposal to replace the perspective accepted in legal theory, in which the agent of law is considered to be a legal norm, with a “reverse perspective” associated with the concept of a legal construction seems pertinent. Seeing the ontological basis of legal institutions and the starting point of the analysis of law in the claims of the individual, and the most important task of law — in preserving the human cosmos in a state of unity, Yu. E. Permyakov associates the current crisis of law with the inability of the agent to acquire shape, declaring his claims to status, and with the crisis of sociality, in which society loses itself as a whole. The author analyzes the phenomena of provincial comprehension of law and political manipulation of legal consciousness as factors that are directly related to the crisis, reflects on how the latter manifests itself in legal practice, legal science and education
Case of severe liver damage in COVID-19
No full textThe 2019 outbreak of coronavirus disease (COVID-19) caused by severe acute coronavirus 2 respiratory syndrome (SARS-CoV-2) has been a global concern since December 2019. Although most patients with COVID-19 have mild clinical manifestations, in about 5% of these patients the disease eventually progresses to severe lung injury or even multiple organ dysfunction. This situation presents various problems for hepatology. In the context of liver damage in patients with COVID-19, several key problems need to be addressed. For example, it is important to determine whether a SARS-CoV-2 can directly enter the liver, especially when it appears that ACE2 is marginally expressed in hepatocytes. In addition, the mechanisms underlying liver dysfunction in patients with COVID-19 are multifactorial and are associated with hyperinflammation, dysregulated immune responses, abnormal coagulation, and drugs. The article describes the potential pathogenesis of liver damage associated with COVID-19. Histopathological evidence suggests a marked disruption of the intrahepatic network of blood vessels secondary to systemic changes caused by a virus that can trigger a coagulation cascade and damage the endothelial layer of blood vessels. There is also a clinical case of polyethylene damage to the liver in a young man who led to death. Against the background of infection COVID-19 he developed massive thrombosis of the liver vessels, followed by the development of necrosis — fibrosis — cirrhosis — acute liver failure, which caused death

Yu. E. Zavoyko’s Memories as a Source on History of Far Eastern Theatre of Crimean War of 1853-1856
No full textThe article analyses notes-memories of Yulia Egorovna Zavoyko (1819-1892), wife of the famous Russian military leader, Admiral Vasily Stepanovich Zavoyko (1810-1898). The literary heritage of Yu. E. Zavoyko is regarded as an important historical source on the history of Kamchatka and the Kamchatka theatre of the Crimean war of 1853-1856. The relevance of the topic is due to the great interest that nowadays manifests itself to the historical problems of gender, first of all - to the understanding of the role of a woman in the historical process. Scientific novelty of research consists in the fact that the literary heritage of Yu. E. Zavoyko by the date has not been the subject of research. It is noted that her name is now known mainly only to professional historians and those who are interested in the history of Russia. It is reported that Yu. E. Zavoyko was born in an aristocratic family and was a relative of a whole group of famous Russian historical figures. It is emphasized that a number of memoirs and scientific works are devoted to the Kamchatka events of 1854-1855. It is stated that some works are devoted to Yu. E. Zavoyko herself and her famous husband, but her memories were not given worthy attention. It is argued that these memories favourably differ from all other works by the fact that they are written by a woman, wife and mother, and therefore do not cover the “battle” (and well-known), but the everyday, everyday side of life and defence of Petropavlovsk-Kamchatsky. It is added that their author was able to contain a fairly large amount of valuable historical, ethnographic and geographical information in a small number of written pages
Appropriations of Irish drama by modern Korean nationalist theatre : a focus on the influence of Sean O’Casey in a colonial context
No full textMy thesis explores how a translated author on the periphery of the host culture’s
translated repertoire can be at once subversive and innovative on the colonial scene,
using as an example the case of Sean O’Casey in colonial Korea. It explores the
importation of Irish drama in modern Korean theatre during the colonial period and
examines the appropriations of O’Casey’s plays by a central Korean playwright, Yu
Chi-jin, in creating his own plays. Under Japanese colonial rule in the early twentieth
century, intellectuals perceived the supreme task for the Korean people to be the
recovery of national sovereignty and independence. The modern Korean theatre
movement which rose among Korean intellectuals and dramatists during the colonial
period was to play a major part in this task. The ultimate goal of this movement was
to establish a modern national theatre promoting Korean culture and educating the
people, thereby recovering national independence. As their modernised dramatic
polysystem was still "young", Korean intellectuals and dramatists who were
involved in the theatre movement had to borrow dramatic models from other
countries. One of the models they chose was Irish playwrights, especially those who
were involved in the Irish dramatic movement. They published or staged the works
of W.B. Yeats, Lord Dunsany [Edward John Moreton Drax Plunkett], Augusta
Gregory, J.M. Synge, St. J. Ervine, T.C. Murray and Sean O'Casey. Although
O'Casey was considered an important dramatist in the Irish dramatic movement, he
was a playwright on the periphery in the list of translated Irish dramatists in Korea
due to the colonisers’ censorship. However, he remained as a subversive and
innovative playwright on the colonial scene by virtue of being appropriated by Yu
Chi-jin who used O’Casey’s plays as models when creating his own works. In
discussing the subject matter of my thesis, I use Even Zohar’s polysystems theory as
a starting point in looking at ideological issues surrounding translation and extend
the discussion to offer a postcolonial perspective. While most translation in a
colonial context was considered as "an expression of the cultural power of the
colonisers," my thesis shifts the focus to translation as an expression of the cultural
power of the colonised. I explore how the colonised uses another colonised culture to
subvert the colonisers’ power
