No full textPicemelinus irinae sp. nov. Alekseev & Grzymala (Figs. 8–9) Material examined. Holotype No. 890 - 5 [CCHH], male (Figs. 8–9). The beetle inclusion is preserved in a polished piece of transparent amber with a yellowish shade without any further fixation. The piece is small, irregular in form, with maximum length 12 mm and maximum width 8 mm. The syninclusions are represented by two trichomes. Etymology. Matronymic, this new species is dedicated to the mother of the first author—Irina I. Alekseeva. Type strata. Baltic Amber. Eocene. Type locality. Russia, the Kaliningrad region, the Sambian [Samland] peninsula, Yantarny settlement [formerly Palmnicken]. Description. Length 1.8 mm; moderately convex, elongate. Unicolored, black. Upper surface biseriate, clothed with very short pubescence, one seta arising anterad of each puncture, with additional short, numerous setae between primary pubescence (pruinose pubescence). Body length 1.9 × maximum body width. Elytral length 3.6 × pronotal length. Head. Eyes large, oval, hemispherical, with slight anterior emargination, well-separated from hind margin of head; interocular space narrower than one ocular diameter; temples approximately 1 / 3 of minimum ocular diameter; apical maxillary palpomere elongate triangular; vertex covered by pubescence equal in length and width to elytral pubescence. Antenna (Fig. 8 B) filiform, 11 -segmented, pubescent, reaching middle of elytra when folded backward; scape, antennomere III, and antennomere XI longest; antennomere length ratios: 14 - 4-20 - 5 - 5-6 - 6 - 6 - 6 - 6- 11; antennomere III with two apical projections forming cavity for antennomere IV. Thorax. Pronotum (Fig. 8 A) transverse, width 0.7 × length, widest apically, with very shallow impression laterad of basal angle, disc with pubescence indistinct, punctation dense and coarse. Scutellum subquadrate, without visible punctation or pubescence. Elytron with short, simple pubescence, moderately convex, with slight depression on disc in basal third near suture; sides weakly rounded; width 0.7 × length; punctation dense and coarse; punctures finer towards lateral aspects of disc. Abdomen. Separation of abdominal ventrite I and abdominal ventrite II visible medially and laterally. Legs. Metafemur simple, without visible brush or comb of modified setae. Metatarsomere I length 3.0× metatarsomeres II–IV combined, metatarsomere II bilobed, metatarsomere III concealed. Diagnosis. Picemelinus irinae sp. nov. differs from the only extant described member of this genus from Japan, Picemelinus flabellicornis (Pic, 1910), by the simple instead of flabellate antennomeres V–X. The elongate scape and the very distinctive length and shape of antennomere III provide evidence for the congeneric status of these two species.Published as part of Alekseev, Vitalii I. & Grzymala, Traci L., 2015, New Aderidae (Coleoptera: Tenebrionoidea) from Baltic and Bitterfeld amber, pp. 239-257 in Zootaxa 3956 (2) on pages 244-245, DOI: 10.11646/zootaxa.3956.2.5, http://zenodo.org/record/23222

Note. This newly described species is found within Danish and in true Eastern (Sambian) Baltic amber. The fossil species is variable in color and pronotal relief. Specimen 290 - 4 is darker, unicolorous and has the pronotum with more expressed tubercles and the median impression with deeper, more distinct punctures. We interpret these characters as polymorphic within the single species here described because other significant morphological differences were not found.Published as part of Alekseev, Vitalii I. & Grzymala, Traci L., 2015, New Aderidae (Coleoptera: Tenebrionoidea) from Baltic and Bitterfeld amber, pp. 239-257 in Zootaxa 3956 (2) on pages 242-243, DOI: 10.11646/zootaxa.3956.2.5, http://zenodo.org/record/23222
“Meek Russian Genius”: Reception of Andrei Platonov’s Prose in the Diaries of G.I. Alekseev
No full textOn the material of the diary prose of the Leningrad poet, prose writer, and artist G.I. Alekseev (1932–1987), the article traces his perception of the personality and work of Andrei Platonov. The author of the diary could get acquainted with Platonov’s prose in the late 50s or early 60s. References to Platonov have been found in the diary since 1963. They relate either to the literary fate and reputation of the writer, or his attitude, manifested in style. Platonov invariably appears among the best stylists-prose writers of the 20th century. Alekseev, a Leningrad free verse writer, not recognized by the professional community, projects his reflections on the literary fate of Platonov onto his own life in literature. In his notes, Alekseev fixes such features of Platonov’s poetics as childishness, even infantilism, and at the same time the wisdom of looking; “childish freshness of language” despite the fact that “the words are all old”; addressing the main issues of being (good and evil, life and death); special interest in the problem of human mortality and its overcoming. “Intimacy,” the ability to see through everyday life, “bewilderment before being,” persistent asking of questions — all this makes Alekseev one of Platonov’s followers, not at the level of imitation, but at the level of community of the aesthetic and ideological platform. Platonov became a landmark for many writers who overcame socialist realism, and Alekseev is among them

Mikhail Alekseev as an Anglicist: Prehistory
No full textThe article deals with the early work of the outstanding Russian philologist academician M.P. Alekseev (1896–1981). A brilliant connoisseur of classical Russian literature, primarily the works of A.S. Pushkin and I.S. Turgenev, the author of numerous works on the history of foreign literature, mainly Western and Eastern European, he was the largest comparativist in our country, a historian of Russian-French, Russian-German, Russian-Spanish, Russian-Portuguese, Russian- Italian, Russian-Hungarian and Russian-Polish literary ties of various eras. However, he modestly considered only the literature of England and Russian-English literary and cultural relations as the main areas of his scientific interests. His studies of the history of English literature began with the translation from German of the pioneering article by the Austrian anglicist, Professor Karl Brunner of the University of Innsbruck, Wirtschaftslage und Literatur (1925). This translation was published in 1930 in Irkutsk in a separate brochure entitled Economic Situation and Literature. Alekseev provided the text of the article with an extensive preface and detailed notes, which contained abundant and diverse factual material. The scientific apparatus included in this relatively small translation testified to the phenomenal erudition, breadth of interests, and depth of thought for a young scientist. His subsequent works on English philology, as well as his scientific activity in general, fully confirmed this
On the Itô-Alekseev-Gröbner formula for stochastic differential equations
No full textIn this article we establish a new formula for the difference of a test function of the solution of a stochastic differential equation and of the test function of an Itô process. The introduced formula essentially generalizes both the classical Alekseev-Gröbner formula from the literature on deterministic differential equations as well as the classical Itô formula from stochastic analysis. The proposed Itô-Alekseev-Gröbner formula is a powerful tool for deriving strong approximation rates for perturbations and approximations of stochastic ordinary and partial differential equations.19 page

According to the World Health Organization, glaucoma is the second leading cause of blindness in the world. Pharmacotherapy for glaucoma implies long-term instillations of IOP-lowering drugs. However, more glaucoma medications per day are required with time. In these cases, fixed-dose combinations containing several active ingredients are beneficial. Potential advantages of fixed-dose combinations include reduced costs, lower risk of washout, less instillations, reduced medication regimen complexity, and saved time. This results in better treatment compliance. Reduced preservative exposure is important as well. Many studies have demonstrated that preservatives induce local adverse reactions. Elimination or minimization of adverse reactions accompanying long-term glaucoma therapy is an important resource to improve treatment compliance and, therefore, to prevent vision loss and to maintain the quality of life. Hence, glaucoma patients may benefit from the avoidance of the addit ional risk of ocular surface disorders resulting from preservative exposure.
Keywords: glaucoma, intraocular pressure, monotherapy, combined treatment, fixed-dose combinations, prostaglandin analogues, ocular surface, compliance, tafluprost, Tapticom.

Philosophical and anthropological foundations of law in light of the ideas of the outstanding scientist Sergei Sergeevich Alekseev
No full textIntroduction. The article is devoted to the scientific legacy of the outstanding scientist and politician Sergei Sergeevich Alekseev in the development of the philosophical foundations of the theory of law. His scientific work is a notable phenomenon in the legal life of the country. The founder of the Ural scientific school in the theory of state and law, corresponding member of the USSR Academy of Sciences, head of the Institute of Philosophy and Law of the Ural Branch of the USSR Academy of Sciences, S. S. Alekseev was one of the main developers of the Constitution of the Russian Federation. He played a prominent role in creating the foundations of the rule of law in Russia. Theoretical analysis. The philosophical heritage of the scientist, the philosophical and anthropological doctrine of law, where its extra-legal foundations are identified and its role and significance are rethought, were analyzed. The author’s main provisions on the beginning of initial rights were revealed. The substantiation of the scientific process of the ascent of positive law with the gradual growth of its natural-legal coordinates was considered. The ethno cultural certainty of law was distinguished in the doctrine of S. S. Alekseev, with an appeal to the biological nature of man, his mindset and mentality. Empirical analysis. The modernity of the scientist’s ideas in relation to the present was highlighted. Based on the empirical material of the normative consolidation of the customs of the peoples of the country, the idea of confirming the doctrine of S. S. Alekseev on the conditions of the effectiveness of law, taking into account the philosophical and anthropological component, was substantiated. The connection of the scientist’s doctrine with the current urgent problems of saving the peoples of Russia was established. Results. The philosophical foundations of legal anthropology deepen, concretize and develop knowledge about law as a specific social phenomenon. The philosophical and anthropological aspect makes it possible to discover the dialogic structure of law, where its moral component can be traced. The merit of the scientist in developing the doctrines of not only law as an idea in its universal understanding, but also national law was demonstrated. It was revealed that the value of each legal norm and law will manifest itself if it corresponds to the dynamics of public life and the tasks set for the transformation of society
