This work is focused on the image processing using the OpenCV library and detectingmoving objects in video using convolutional neural networks. The created application can detectmoving objects in the video and contains additional functionality. The application includes theYOLO convolutional model, which helps to detect moving objects.

In this paper, we present two pipelines in order to reduce the feature space for anomalydetection using the One Class SVM. As a first stage of both pipelines, we compare the performanceof three convolutional autoencoders. We use the PCA method together with t-SNE as the first pipelineand the reconstruction errors based method as the second. Both methods have potential for theanomaly detection, but the reconstruction error metrics prove to be more robust for this task. Weshow that the convolutional autoencoder architecture doesn’t have a significant effect for this task andwe prove the potential of our approach on the real world dataset.

AbstractWe provide a theory to identify a new benefit for conglomerate mergers. In this paper, projects are subject to manager‐specific shocks. Bringing projects under the same top management in a conglomerate increases the correlation of shocks. We show that this positive correlation, in contrast to traditional wisdom, enhances a firm's ability to relax financial constraints. This is because common managerial shocks help conglomerates better take advantage of cross‐pledging possibilities. This paper also contributes to the literature by providing one of the first studies to emphasize the role of manager‐specific shocks in shaping a firm's choice to be a conglomerate or standalone.

Phoebe Apperson Hearst měla velmi úspěšného vlastního syna Williama, který byl ale více jako jeho otec: tvrdý obchodník. Našla však jemnou, uměleckou duši v malíři Orrinu Peckovi (1860–1921), který byl údajně gay a který ji, ještě za života své vlastní matky, začal oslovovat „má druhá mámo.“ Na základě podrobného výzkumu jejich vzájemné korespondence v Peckově pozůstalosti se můžeme ptát, jak moc si byla progresivní, bohatá žena 19. století, jakou byla Phoebe Hearst, vědoma Peckovy sexuality a pokud ano, jestli s tím neměla problém, nebo šlo o nevyřčené tajemství mezi nimi? Jejich příběh představí historik umění Ladislav Zikmund-Lender. Phoebe Apperson Hearst had a very successful son of William, but he was more like his father: a tough businessman. However, she found a delicate, artistic soul in the painter Orrin Peck (1860–1921), who was allegedly gay and who, while still his own mother's life, began to address her as “my second mother.” Based on a detailed study of their correspondence in Peck's estate, we may ask how much a progressive, rich 19th-century woman like Phoebe Hearst was aware of Peck's sexuality, and if so, if she had no problem with it, or was it an unspoken secret between them? Their story will be presented by art historian Ladislav Zikmund-Lender.

AbstractJim Grimsley (b. 1955) is a southern author of literary fiction, literature of the fantastic as well as numerous plays whose road to publishing success in the United States has been a thorny one. Grimsley had published two novels in Germany with translations to French and Dutch under way before his first novel, Winter Birds, was put out in 1994 by Algonquin Books of Chapel Hill following 10 years of futile attempts to get the book to press in his home country. Since the publication of Winter Birds in the United States, he has published six literary novels, three science fiction or fantasy novels, a collection of short stories, a book of plays, and a memoir in English. Although Grimsley explores topical themes in his fiction such as child abuse, class issues in the United States, same‐sex relationships in the American South, as well as the relationship between technology and society, he surprisingly remains one of the most under‐researched contemporary American writers. Nevertheless, the amount of research on the author has been growing in the last 20 years, so there can be no doubt about his inclusion in the canon of contemporary southern literature. The present article provides an overview of scholarship on Grimsley both in the United States and Europe, identifying several main research areas: (southern/queer) Gothic elements, abuse in all its forms, southern culture and its elements (region, space, class), gay identity, literature of the fantastic, and theatrical plays. As this overview and bibliography of research into Grimsley up to the present is meant to further current research and stimulate interest in the author and his works, the article also identifies new areas that deserve scholarly attention.

Lermontov’s verse “Through the mist, the road gleams with stone” from his poem I come out to the path, alone appears as a motif of a quartz path in Nabokov’s novella Glory. This motif also makes a connection between Lermontov’s poem and Nabokov’s memoir Speak, Memory and novel The Gift. In this last work written in Russian, Nabokov subscribes to the romantic tradition and symbolist poetics, which highlighted the crystal as the ideal of a work of art. The basic property of the crystal is transparency, which also appears in the poems of Vyacheslav Ivanov and Osip Mandelstam as a symbol of the purity of the poetic work. Both phenomena, the quartz path as a metaphor for the poet’s journey and the crystal as a metaphor for the written work, are connected in the author’s reflection of the work of art as a time-space polyhedron permeated by memory. Nabokov perceives time as a constant division into the present and the past, as Deleuze writes about it in his book Cinéma 2. L’image-temps. The crystal becomes a metaphor for transparent work, which is also pervaded by Nabokov’s language. For Nabokov, memory resembles a film in its original meaning, a film like a fine chiffon, a thin coating of meaning. This is most evident in Nabokov’s late novella Transparent Things. The same is true of Ivanov’s collection of poems Transparency or Mandelstam’s poem The Slate Ode. In both Nabokov’s novel and Mandelstam’s poem, the act of writing becomes an act of memory.

We propose the model combining convolutional neural network with multiple instancelearning in order to localize the premature atrial contraction and premature ventricular contraction.The model is based on ResNet architecture modified for 1D signal processing. Model was trainedon China Physiological Signal Challenge 2018 database extended by manually labeled ground truthpositions of premature complexes. The presented method did not reach satisfying results in PAClocalization (with dice = 0.127 for avg-pooling implementation). On the other hand, results of localizationof PVCs were comparable with other published studies (with dice = 0.952 for avg-poolingimplementation).

This article commemorates the centennial of Harry J. Benda (1919-1971), a legendary figure of Southeast Asian Studies of Czechoslovak origin. As a young man, to escape the Nazi threat in Europe, Benda fled to Java. He spent seven formative years in the Indies, including internment in a Japanese camp, where he decided to pursue an academic career, focussing on the history of Indonesia. He received his university education in New Zealand and Cornell University, and to crown his achievements became a professor at Yale and served as founding director of the Institute for Southeast Asian Studies in Singapore. He researched Islam in Indonesian society, the Japanese occupation, the rise of Communism and nationalism and the decolonization processes in Southeast Asia, and was known for his innovative approach to the study of the regional and social history. He wrote a number of books and dozens of articles, with The Crescent and the Rising Sun (1958) being his most acclaimed work.

AbstractWe document how Chinese exporters misreport their exports to China's customs in order to benefit from export tax refunds. We estimate the response of the logarithmic difference between the exports reported in China's customs data and the imports reported in destination countries' customs data to export tax refund rates. We find that with an increase of 1 percentage point in export tax refund rates, the logarithmic difference increases by 0.051. Additionally, with an increase of 1 percentage point in the export tax refund rates of similar products, this gap decreases by 0.024. Further study reveals that quantity manipulation accounts for the majority of the export reporting distortion.
