Image features of spinning regular black holes based on a locality principle

To understand the true nature of black holes, fundamental theoretical developments should be linked all the way to observational features of black holes in their natural astrophysical environments. Here, we take several steps to establish such a link. We construct a family of spinning, regular black-hole spacetimes based on a locality principle for new physics and analyze their shadow images. We identify characteristic image features associated to regularity (increased compactness and relative stretching) and to the locality principle (cusps and asymmetry) that persist in the presence of a simple analytical disk model. We conjecture that these occur as universal features of distinct classes of regular black holes based on different sets of construction principles for the corresponding spacetimes.

The first ‘Soviet type’ research institute of the Hungarian Academy of Sciences and its Stalin Prize-awarded director, Imre Szörényi

The Hungarian Academy of Sciences (HAS, established in 1825), similar to the academies of the old Soviet bloc, ran a research network from 1950 until 2019 when it was detached from the Academy. The first research institute of the HAS was the Institute of Biochemistry, which started its operation in 1950. Its first director was Imre Szörényi (1905–1959) who lived in emigration in Kiev until he was called back to Hungary in 1950 by the Secretariat of the Hungarian Workers Party. Initially, for a few years research in the Institute was partly influenced by Lepeshinskaya's ‘New Cell Theory’ and Szörényi himself became the chair of the ‘Living Protein’ Committee of the HAS. He returned for more than two years to Kiev where he received a shared Stalin Prize in 1952 for the development of the antibiotic, Microcid. After his final return to Hungary in 1953, he was able to shape the characteristic image of the Institute of Biochemistry, making it one of the leading workshops of Hungarian biochemistry. From 1956 onwards, ideological considerations no longer interfered with the choice of research topics. The relationship between the chemical structure and the specific biological function of enzymes became the main profile of the Institute. In spite of his untimely death, Szörényi exerted a long-lasting influence on Hungarian biochemistry through his disciples.

Matryoshka version of the Russian verlibre

  Referring to the possibility and need for an experiment in literary studies, mentioned in the early XX century by the Soviet literary theoretician and poetry scholar Boris Yarkho, who paid particular attention to the transformation of the genre and the structure of expressive means as a whole, the author of this article analyzes the new form of the Russian verlibre (free verse), its varieties of the most probable form, attempting to determine its most characteristic typology, as well as to introduce into the concept of the matryoshka verlibre the two main forms, two of its fundamental metaphases and several subvarieties: 1. Verlibre in verlibres (verlibre in several verlibres); 2. Verlibre in verlibre  (several verlibra in one verlibre). The author also distinguishes two subvarieties that are formed from the verlibre in verlibre: 3. Veprlibr (large verlibre in several verlibres); 4. Aphoristic verlibre (verlibre in several aphorisms), and others. The main conclusion of the conducted analysis of the new form of the matryoshka verlibre consists in the fact that matryoshka verlibre is patterned by a catenate fairy tale and is attributed to the type of catenate fairy tale (cumulative fairy tale, recursive fairy tale, chainlike fairy tale). The verlibre, in which dialogues or actions are repeated and develop in a modified form according to the plotline, belongs to the matryoshka verlibre. The effect of these verlibres is based on the repeating narrative, characteristic image and action changing for one or another reason and reaching culmination. In this case, semantic differentiation of the text is viewed as a synthesis of both dimensions, where any component of the work is simultaneously motivated by the coherence of such element that it creates with other elements, as well as semantic union of the elements that are subject to destruction, and belong to different components of the entire work. A matryoshka doll serves as an example.  

Een 19-jarige jongen met kniepijn, gerefereerd vanuit een middiafysair osteoïd osteoom van de femur?

A 19-year-old male with persistent unilateral knee pain, possibly due to a mid-diaphyseal osteoid osteoma of the femur? Osteoid osteoma is a benign bone-forming tumor that typically presents itself during the second decade and more frequently in males. The main complaint is progressive pain, usually pain at night. The pain is relieved by nonsteroidal anti-inflammatory medication. However, osteoid osteoma can present itself in a rather nonspecific pattern, for example with referred pain. On radiographs an osteoid osteoma has a characteristic image of a small round lucency (nidus) with sclerotic margin, which is best visualized with CT scan. Treatment can either be conservative with an oral NSAI or surgical, where nowadays CT guided radiofrequency ablation seems to be the primary choice.

Research on Low-Resolution Pattern Coding Recognition Method Based on Hu-DBN

The feature image code represented by the two-dimensional code is the key reference for global positioning in the visual navigation of mobile robots. Although reducing the acquired low-resolution image helps to reduce the real-time performance of the algorithm, the acquired feature image is more susceptible to motion blur-based interference and affects the accuracy of recognition, which causes the positioning failure of the whole multi-intelligence, in which the body control system is invalid. In this paper, an optimized low-resolution feature image code recognition method is proposed. In the preprocessing part, the characteristic image is converted into the characteristic signal matrix of Hu invariant moments, and then the characteristic image is added to the characteristic signal matrix as a characteristic component, and then the Hu-DBN neural network signal classifier is used to construct the signal matrix so as to achieve accurate recognition of low-resolution custom image signature images under high motion tolerance conditions. It not only avoids the problem of classical pattern recognition relying on model experience and poor adaptability of the scene, but also avoids the problem of high computational complexity and recognition efficiency of directly deep learning methods such as YOLO. The deployment of the mobile robot instance deployment test shows that the average recognition rate is of 96.3% at a resolution of 640×480@Pixs and motion speed of 0.5 m/s, which proves the effectiveness of the present method.

Myonecrosis in a Sickle Cell-Diseased Patient: A Case Report and Literature Review

Myonecrosis is a condition that results in muscle tissue necrosis, and it is rarely seen in sickle cell patients and often missed because more common manifestations of sickle cell can overlap like vaso-occlusive crises (VOC), which results in pain in the extremities or spine; also osteomyelitis is commonly seen in sickle cell patients. In this article, we present a case of myonecrosis in a sickle cell-diseased patient who presented with left acute atraumatic left foot pain and MRI with contrast showing characteristic image of muscle infarction supportive therapy initiated, and 2-year follow-up did not reveal any physical disabilities; further study and follow-up are needed to know the nature of the disease and avoid improper management of those patients.

MYTHOLOGIZATION OF THE BASIC CONCEPTS OF THE HEROIC EPIC IN THE SOVIET CINEMA OF THE 1930S AND 1950S

The article analyzes the mythologization of epic images of heroes and enemies, visual space, plots and motives in the domestic cinema of the Stalinist period. The author notes that due to the availability of plots, sometimes naive, but very expressive imagery, and the vastness of the means of artistic expression, the film language has become one of the most popular metalanguages of Soviet mass culture. The Russian cinema of the 1930s and 1950s is conventionally designated, by analogy with the content of the material embodied, «the heroic epic of Soviet culture», not only at the level of content, but also of form. The transformation of existing images and the introduction of new images into the cultural code of the epic can be interpreted as mythologization, that is, the deformation of meaning, according to R. Barth, in which the appearance of these characters is perceived by the viewer as familiar and organic. In the course of analyzing the films, C. The author comes to the conclusion that many epic concepts of the heroic, folk epic formed the basis of the Soviet mythosystem almost unchanged (images of the cultural hero, monster, enemy). The image of the ruler undergoes transformation, while in the folk epic the ruler can act as an antagonist of the hero, in the Soviet cinema of the Stalinist time the image of the ruler is clearly idealized, often through the introduction of the image of the traitor and the transfer of guilt for the cruelty and mistakes of the ruler to it. Thus, the cultural code of the Russian epics includes an idealized image of the ruler, a characteristic image of an internal enemy, a traitor, relevant to the ideology and internal politics of that time.
