On the physical nature of photon and the modeling of its wave function of free propagation in space and time

In the framework of quantum mechanics the physical nature of the photon is discussed. It is substantiated that a photon is a quantum quasiparticle, the free propagation of which must be considered taking into account the processes in a physical vacuum at Planck distances. For practical purposes on a macroscopic scale, the photon propagation can be modeled using the wave function (wave packet) normalized to the unit probability in the coordinate representation

Tijelo/organizam u umjetnosti 1920-ih: o skupini “Elektroorganizam”

Članak je posvećen praksi i manifestu umjetničke skupine “Elektroorganizam” (K. Red’ko i dr.) iz 1920-ih, koja se promatra u kontekstu problema vizualne reprezentacije tijela i modifikacije suprotstavljanja tijela i organizma u ruskoj kulturi 20. stoljeća. Djelatnost umjetničke skupine analizirat će se kroz prizmu filozofije i ideologije 1920-ih, posebice u radovima Pavla Florenskoga, fiziologa i političara Aleksandra Bogdanova, pjesnika i ideologa Alekseja Gasteva i drugih

Пациент с инфарктом миокарда, фибрилляцией предсердий и высоким геморрагическим риском: обоснованный выбор антикоагулянта для эффективной профилактики ишемических событий

Current clinical practice faces the challenges in selecting optimal drugs and the duration of antithrombotic treatment in patients with acute coronary syndrome with atrial fibrillation. A continuous increase of using non-vitamin K oral anticoagulants (NOAC), dabigatran, rivaroxaban, apixaban, edoxaban, and novel antiplatelet agents, prasugrel and ticagrelor, has complicated the decision-making process in this group of patients. The presented clinical case reports the use of dabigatran as a part of double antithrombotic therapy in an elderly patient with type 2 myocardial infarction, paroxysmal AF and a high risk for hemorrhage. The drug choice and its dosage were chosen using the personalized risk assessment. The presented approach has been early proved by the results of the recent randomized clinical trials and, therefore, may be translated into routine clinical practice.В настоящее время в реальной клинической практике имеются сложности понимания правильности выбора препаратов и продолжительности антитромботического лечения у пациентов с острым коронарным синдромом с фибрилляцией предсердий. С учетом непрерывного роста доли использования не-витамин К-зависимых прямых оральных антикоагулянтов (ПОАК) - даби-гатрана, ривароксабана, апиксабана, эдоксабана и активным использованием «новых» антиагрегантов (прасугрель и тикагрелор) принятие решений у этих пациентов стало еще более сложным. Представленный для обсуждения клинический случай демонстрирует применение дабигатрана в составе «двойной» антитромботической терапии у пожилой пациентки с инфарктом миокарда 2 типа с пароксизмальной формой ФП и высоким риском кровотечений. Обсужден выбор препарата и дозировки с учетом данных персонифицированной комплексной рискометрии. Представленный подход является доказанным по результатам ранее проведенных рандомизированных клинических исследований и может быть транслирован в широкую клиническую практику

Representation of <i>Corpus Patiens</i> in Russian Art of the 1920s

Similar to the Russian historical avant-garde of the 1910s, which predicted the war and the social revolution of 1917, the late avant-garde of the 1920s anticipated the advent of the totalitarian terror and the Stalinist repressions of the 1930s. In figurative painting, this manifested itself in a specific visual “lexicon” and modality (bodily violence and the fragmented body, frustration, motifs of loss, death and general catastrophe), as well as in the expressive style (that inherited but not duplicated the models of European expressionism). In addition to proposing an analytical classification of semantics and poetics of the painting of the 1920s, the present article discusses the issue of the representation of political power in visual art and the presence of archaic roots in the corpus patiens (lat.) motifs. It examines artefacts made by eminent as well as little-known painters of the late avant-garde, including Kazimir Malevich, Alexander Tyshler, Kliment Redko, Georgy Rublev, Aleksandr Drevin, Boris Golopolosov and others
