HELIOS-K 2.0 Opacity Calculator and Open-source Opacity Database for Exoplanetary Atmospheres
Computing and using opacities is a key part of modeling and interpreting data of exoplanetary atmospheres. Since the underlying spectroscopic line lists are constantly expanding and currently include up to ~1010–1011 transition lines, the opacity calculator codes need to become more powerful. Here we present major upgrades to the HELIOS-K GPU-accelerated opacity calculator and describe the necessary steps to process large line lists within a reasonable amount of time. Besides performance improvements, we include more capabilities and present a toolbox for handling different atomic and molecular data sets, from downloading and preprocessing the data to performing the opacity calculations in a user-friendly way. HELIOS-K supports line lists from ExoMol, HITRAN, HITEMP, NIST, Kurucz, and VALD3. By matching the resolution of 0.1 cm−1 and cutting length of 25 cm−1 used by the ExoCross code for timing performance (251 s excluding data read-in time), HELIOS-K can process the ExoMol BT2 water line list in 12.5 s. Using a resolution of 0.01 cm−1, it takes 45 s, equivalent to about 107 lines s−1. As a wavenumber resolution of 0.01 cm−1 suffices for most exoplanetary atmosphere spectroscopic calculations, we adopt this resolution in calculating opacity functions for several hundred atomic and molecular species and make them freely available on the open-access DACE database. For the opacity calculations of the database, we use a cutting length of 100 cm−1 for molecules and no cutting length for atoms. Our opacities are available for downloading from https://dace.unige.ch/opacityDatabase and may be visualized using https://dace.unige.ch/opacity
Tautological relations and integrable systems
We present a family of conjectural relations in the tautological cohomologyof the moduli spaces of stable algebraic curves of genus with markedpoints. A large part of these relations has a surprisingly simple form: thetautological classes involved in the relations are given by stable graphs thatare trees and that are decorated only by powers of the psi-classes athalf-edges. We show that the proposed conjectural relations imply certainfundamental properties of the Dubrovin-Zhang (DZ) and the double ramification(DR) hierarchies associated to F-cohomological field theories. Our relationsnaturally extend a similar system of conjectural relations, which were proposedin an earlier work of the first author together with Gu\'er\'e and Rossi andwhich are responsible for the normal Miura equivalence of the DZ and the DRhierarchy associated to an arbitrary cohomological field theory. Finally, weprove all the above mentioned relations in the case and arbitrary using a variation of the method from a paper by Liu and Pandharipande, this canbe of independent interest. In particular, this proves the main conjecture fromour previous joined work together with Hern\'andez Iglesias. We also prove allthe above mentioned relations in the case and arbitrary .Comment: v3: final journal version, 44 page
Sergey Eisenstein: the revolutionary in the screen culture and a mythmaker
Статья поступила в редакцию 06.06.2017 г.Рассматривается многогранное творчество Сергея Эйзенштейна — признанного гения мировой культуры XX в. Автор, анализируя его фильмы, а также тексты теоретических работ Эйзенштейна и других исследователей, показывает художника с двух сторон: как великого режиссера-реформатора, создателя языка «интеллектуального кино» и как основоположника экранной мифологии, базирующейся на политических идеях революционной эпохи.The article considers multifaceted creativity of Sergey Eisenstein — a recognized genius of the world culture of the 20th century. The author, analysing his fi lms, as well as the texts of the theoretical works of Eisenstein and other researchers, approaches the artist’s personality and creativity from two perspectives: as of great reform director, the creator of the language of “intellectual cinema”, and as the founder of the screen mythology based on political ideas of Revolutionary era
‘The Noblest Soul’: A Sad Page in the History of the Grand Duchy of Hesse through the Eyes of Grand Duke Sergey Alexandrovich. The Darmstadt Diary, 1892
This is the first publication of a fragment of the diary of Grand Duke Sergey Alexandrovich of Russia for 1892 describing illness, death, and burial of Grand Duke Ludwig IV of Hesse and by Rhine, head of one of the states forming a part of the German Empire. Ever since the 18th century the Russian Imperial Family was bound by close kinship to the Hessian ducal family. The author of the diary was a member of the House of the Romanovs, a younger brother of Russian Emperor Alexander III. Grand Duke Sergey Alexandrovich held the post of the Moscow Governor-General. In 1884 he married Grand Duchess Elizabeth Feodorovna, n?e Princess of Hesse, who was a daughter of Grand Duke Ludwig IV. This publication includes diary records from February 26 to March 9, 1892, covering the time when Grand Duke Sergey Alexandrovich and his wife were staying in Darmstadt. The diary describes the daily life of the Royal family in the capital of the Grand Duchy of Hesse and by Rhine during said period and the participation in the obsequies of the deceased’s family and the representatives of the Russian, British and German ruling dynasties. Among others, the Grand Duke Sergey Alexandrovich’s diary mentions German Dowager Empress Victoria (the mother of Emperor Wilhelm II), Prince Henry of Prussia (the future Grand Admiral of the Imperial German Navy), Prince Louis Battenberg (the future British First Sea Lord), Princess Alice of Hesse, the younger sister of Grand Duchess Elizabeth Feodorovna, future Russian Empress Alexandra Feodorovna. The daily entries record family unity of the members of the Russian, the German, and the British Royal dynasties in the face of common tragedy against the backdrop of difficult relations between their empires. The deceased, Grand Duke Ludwig IV, enjoyed universal respect. Diaries of Grand Duke Sergey Alexandrovich are stored in his personal provenance fond in the State Archive of the Russian Federation (Moscow).</jats:p
Russian History by Sergey Solovyov in Fyodor Dostoevsky’s Novel The Idiot
For the first time in Dostoevsky studies, the article examines the influence of the historical works of the eminent Russian scholar, professor at the Imperial Moscow University Sergey Solovyov (1820-1879), on the novelist’s work. It is known that Dostoevsky carefully read these texts, repeatedly mentioned them and had them in his home library. The presence of Solovyov’s History of Russia in Dostoevsky’s artistic world is explored as a book within a book, using material from the novel The Idiot. Solovyov’s History fulfils the function of Holy Scripture for Rogozhin, who reads it in order to “educate” (rus. obrazovat’) himself, following Nastasya Filippovna’s suggestion. Rogozhin’s mission to transform his personality by reading historical literature turns out to be unbearable and a failure, as feelings of jealousy, resentment and revenge prevail over the ideals of sacrifice, brotherhood and piety. The article proves that Rogozhin is not actually reading the History of Russia from the Earliest Times, as the commentators of the first and second editions of the academic Complete Works of Dostoevsky believed, but the one-volume Textbook of Russian History by the same author: first published in 1859–1860, it had gone through seven editions by the time The Idiot was published. The article analyses which passages from this book may be particularly relevant to Rogozhin, given the novel’s overall plot and Rogozhin’s complex relationship with Prince Myshkin and Nastasya Filippovna
Mother as donor, hero or villain: new sides of the mother’s image in Sergey Sedov’s "Fairy tales about mums"
A new model of society in post-Soviet Russia introduced novel family patterns to everyday life as well as to children’s literature, with traditional parent and children’s functions becoming subject to rethinking. The tendency to reconsider parental functions can be observed in texts from different genres, but it appears most overtly in modern fairy tales which, on the one hand, link modernity with the national folkloric code but, on the other, aim to overcome the code. Unlike many contemporary Russian authors for children, who leave little narrative space for parents, Sergey Sedov makes the mother central to his “Fairy Tales About Mums.” He describes various situations in which this figure regains the depth and comprehensiveness of a Jungian Great Mother Archetype. The author combines different fairy tales, cultural stereotypes and literary themes to create the image of a new mother who possesses various roles, some of which place her in opposition to the gender stereotype of patriarchal Russian folklore. This article uses structural, typological and motive methods of analysis to trace the transformation of the mother’s image from the traditional folktale canon to determine its activity-related and axiological aspects and to analyse various manifestations of the mother in terms of the tales’ semantic and aesthetic integrity

High Accuracy Molecular Line Lists for Studies of Exoplanets and Other Hot Atmospheres
The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy. However, this goal is impacted by the lack of spectroscopic data on the molecules in question. As most atmospheres that can be studied are hot, some surprisingly so, this activity requires spectroscopic information not readily available from laboratory studies. This article will review the current status of available molecular spectroscopic data, usually presented as line lists, for studies of exoplanet atmospheres and, indeed, the atmospheres of other astronomical objects hotter than the Earth such as brown dwarfs, cool stars and even sunspots. Analysis of exoplanet transit spectra and the calculation of the relevant opacities often require huge datasets comprising billions of individual spectroscopic transitions. Conversely, the newly-developed high-resolution Doppler-shift spectroscopy technique has proved to be a powerful tool for detecting molecular species in exoplanet atmospheres, but relies on the use of smaller, highly accurate line lists. Methods of resolving issues arising from the competing demands of completeness versus accuracy for line lists are discussed

Summary
Despite the high efficiency of the etiotropic antiviral drugs and antiviral vaccines they can lead to the selection of resistant mutant variants, initiate of evolutionary "arms race" [1] and pose a threat of the superinfections and epidemics. In this regard, the creation of means that enhance non-specific antiviral resistance is actual task and will be such in the future. The development of such agents – the functional analogues of amixyne (tilorone) – inducers of IFN type I is conducted in the past decades in O.V. Bogatsky Physico-Chemical Institute of the National Academy of Sciences of Ukraine. As an inactive model compound 4,4'-bis-[2-(diethylamino)ethoxy]bi-phenyl was synthesized in 2005 and unexpectedly appeared as an active antiviral and interferon inductor [2]. In this regard, analogues of this compound is of considerable interest from the point of view of the structure-properties relationships. These substances (R-A-4DP4-A-R, R – amino group of different structure; A = -(CH2)nO-, n = 2 - 6; 4BP4 - 4,4'-biphenyl) were synthesized via halogenoalkylation of 4,4-dioxybiphenyl with dihalogenoalkanes following with amino dehalogenation.

Holotype and four paratypes are deposited in the collection of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia), other paratypes, in the private collection of S.K. Korb (Bishkek, Kyrgyzstan). Description (Figs 1–6). Male. Forewing length 10–12 mm. Head, thorax, abdomen, and legs are grey to dark brown. The eyes and antennae are dark-brown. Labial palpi are twice longer than the diameter of the eyes. The upperside and underside of the wings from grey to dark brown. The wing pattern is poorly developed, represented by a slightly lighter longitudinal stroke in the anal part of the forewing and by several (1–6) light strokes on its external margin. Fringes lighter than wing ground color. Female. Unknown. Male genitalia (Figs 7–11). Uncus wide, bilobed, with rounded median notch. Gnathos is longer than uncus, narrow, with a short, pointed apex. Vinculum is massive, with two large lateral lobes of the same length as the valva. Valva triangular, basal part widened dorsally; sacculus with long caudal, apically pointed projection; cucullus with weak and only slightly visible apical hairy lobe; costal part ends with triangular and slightly pointed projection reaching only the base of the projection of sacculus. The aedeagus is longer than the valva, straight, with a sclerotized longitudinal crest of about 1/4 of its length, apical part of this crest with a small pointed tooth. Diagnosis. N. olini sp. n. differs signifiсantly from N. wolfschlaegeri by its wing pattern and coloration. In N. wolfschlaegeri, the wing pattern is not developed, forewing yellowish and hindwing brownish (see Slamka 2008: pl. 16, figs 121a–121c); in N. olini sp. n., the wing pattern is present and both pairs of wings are of the more or less same color, from grey to dark-brownish. The male genitalia in general are the same as in N. wolfschlaegeri (see Slamka 2008: pl. 21, fig. 121), but in N. olini sp. n. the costal margin of valva has a wide basal protrusion and both apical projections are wider. Etymology. The new species is named in honor of Mikhail Olin, a member of HDD Research Group and a good friend of the second author, who passed away in 2021 as a result of COVID19. Biology. N. olini sp. n. was found in different biotopes at altitudes from 500 to 2100 m: Turanga forest in the river valley (Fig. 12), dry meadows in the walnut forest (Fig. 13), and open dry steppe (Fig. 14). The moths were attracted at the light between 22:00 and 24:00.Published as part of Sinev, Sergey Yu. & Korb, Stanislav K., 2022, A new species of the genus Neocrambus Bleszynski, 1957 (Lepidoptera: Crambidae) from Central Asia, pp. 594-597 in Zootaxa 5209 (5) on pages 594-597, DOI: 10.11646/zootaxa.5209.5.6, http://zenodo.org/record/734098
