Eosinophilic pneumonia in allergological practice
Authors: Tsarev Sergey V.
Published: April 2021

In this article, current data on pulmonary eosinophilia are presented. Pulmonary eosinophilia is defined as the infiltration of eosinophils into the airways, interstitia, and alveoli. There are diverse processes in etiology, the common feature of which is the presence of pulmonary eosinophilic infiltrates, and as a rule, peripheral blood eosinophilia. Causes of pulmonary eosinophilia include various infections, medications, parasites, autoimmune processes, malignancies, and presence of obstructive pulmonary diseases. A unified classification of pulmonary eosinophilia is lacking, and instead, various versions of classifications have been presented. The most convenient classification option for use is also distinguished. This article discusses the historical transformation of the term eosinophilic pneumonia in the field of allergology, showing the lack of unambiguity in the concept of eosinophilic pneumonia, as well as the location of eosinophilic pneumonia in the pulmonary eosinophilia section. Eosinophilic pneumonia is defined as a disease characterized by an increase in the eosinophil content in the pulmonary tissue or bronchoalveolar lavage fluid. Most eosinophilic pneumonias are associated with peripheral blood eosinophilia. Two main variants of the disease are acute and chronic eosinophilic pneumonias. Thus, various ways to formulate diagnoses in various cases of eosinophilic pneumonia have been proposed.

This paper proposes a substrate integrated waveguide (SIW) filtering slot antenna. Based on four SIW cavity resonators and a slot locating on the last resonator, a filtering antenna was designed, targeting the near 20 GHz satellite communication band. Simulated in the Ansys-HFSS commercial software, it exhibits a - 10 dB impedance bandwidth of 1.5 GHz and a flat gain of 5.5 dBi in the operating frequency band. Besides, the filtering antenna has good selectivity at passband edges and features such as compact size, low profile, and low cost, making it suitable for Ka-band satellite ground terminals.
INTERIOR IN THE ARCHITECTURE OF TRYPILLIA-CUCUTENI CULTURAL COMPLEX (problems of studies, interpretations and reconstructions)
Authors: Burdo N. В.
Published: April 2021

The interior of Trypillian houses is not as available object as the interior of the folk architecture to which it actually belongs. The necessary steps to study the interior of Copper Age houses from archeological sites are:

field research and advanced fixation in field documentation of detected interior details / remains;
interpretation of discovered archaeological data;
reconstruction of identified structural elements — the ultimate goal of the study which can be carried out on the basis of the interpretation of archeological objects using the method of study of buildings used by ethnology.

It is necessary to take into account the sacral load of all elements of the dwelling, as well as the factor of transformation of them in the final stage of the settlement’s life into a ritual object. Formally, the following clay interior details can be distinguished: I — various enhancements, including rectangular and round elevations, side elevations, cruciform elevations, and catwalks; II — special clay storage tanks; III — furnaces.
The analysis of the interior of Cucuteni—Trypillya dwellings shows the unity of the architectural tradition from the early up to the final stages. The origins of these traditions are related to the interior and ritual sphere of dwellings and settlements discovered in the oldest Neolithic Cultures of Europe. Clay interior details are characteristic of the architecture of the neo-neolithic crops of South-Eastern Europe. They are especially often recorded in buildings that were burned in ritual fires. Clay interior designs including in the form of rectangular and circular elevations are recorded in buildings of such cultures as Hamangia III, Boyan, Vedastra, different variants and periods of Vinca Culture. The rituals, similar to Trypillian ones, associated with rituals, known in the cultures of Tisza, Kojaderman-Karanovo-Gumelnitsa, Selkutsa.
IMPORT OR IMITATION: CHARACTERISING THE BUDZHAK CULTURE OF THE NORTH-WEST PONTIC REGION
Authors: Ivanova S. V.
Published: April 2021

Specific feature of the cultural-historical genesis of the North-Western Pontic Region at the turn of the 4th to the 3rd mill. BC is manifested by relations of its population with a foreign cultural environment. This concerns, first and foremost, the Budzhak culture that is a component of the Pit-Grave (Yamna) cultural-historical region. The Budzhak culture represents connections with the Carpathian and Danube, the Corded Ware and the Globular Amphora cultures. The contacts were reflected in two aspects: imports, imitations and parallels in the Budzhak pottery and the occurrence of the Yamna burials found in other territories. Some forms of pottery and elements of its dйcor are rather surprisingly similar to central European groups of the Corded Ware culture. The analysis of the mainland culture of the Budzhak population enables us to assume the existence of contacts with the Corded Ware culture circle as early as in the first half of the 3rd mill. BC.
The current state of research on the movement of Yamna cultural aspect towards west is also discussed in the paper. The recent genetic analysis results the link of Yamna and Corded Ware populations. They were treated as the evidence of direct massive migration of Steppe people into Central Europe. Archaeological data supporting this concept are few if any. The westernmost enclaves of Yamna culture rather indicate limited intrusion of specialized groups aimed at control of exchange routs and raw material extraction places. It is suggested that formation of Balkan-Carpathian variant of Yamna cultural-historical community is connected to the expansion of the tribes of the Budzhak culture of the North-West Pontic region. The western group of Yamna-Budzhac culture is distinctively different from «core» Yamna by typology of pottery while both aspects share the similar burial rites.
The information obtained as a result of many years of excavations of barrows of the North-Western Pontic Region allow defining the Budzhak culture not only as a unique structural entity within the Yamna cultural-historical area but also as a mobile community opened to «cultural dialogue» and capable of long-distance migrations. Indications of that include imports, imitations, derivatives in the material complex, as well as the population’s westward movement to the Central European and Balkan-Carpathian Region.

Authors: Starenkyi I. O. , Levinzon Ye. Yu.
Published: April 2021

The paper deals with the course of exploration of the multilayered archaeological sites of the Middle Dniester within the Kamianets-Podilskyi district of Khmelnytskyi region.
During 2009—2014 P. Boltaniuk (Head of the «Museum of Antiquities» sector of the Kamianets-Podilskyi State Historical Museum-Reserve, hereinafter — K-PSHMR) and I. Starenkyi made a number of explorations on the multilayered site Kamianets-Podilskyi, Tatarysky (Trypillia culture, Chernyakhiv culture, Kievan Rus age) near the Smotrych village.
In 2012 O. Mohylov (Senior Research Fellow, IA NAS of Ukraine) and P. Boltaniuk have explored the multilayered site Malynivtsi on the left bank of the Dniester (Early and Middle Trypillia, Late Chornolis, Early Scy­thian culture, antiquities of the Middle Ages — Modern age).
In 2019 the study of this site was continued by the expedition of the K-PSHMR (authors and P. Boltaniuk) which also made further exploration along the left bank of the Dniester River to the Zhvanets village which permits to survey the sites Malynivtsi, Popivskyi Yar (Trypillia, Early Iron Age, Cherniakhiv, Kievan Rus antiquities), Babshyn (Trypillia A, Chernyakhiv culture), Braga (destroyed).
The authors’ main focus was on the analysis of Middle Trypillia findings from the Kamianets-Podilskyi, Tatarysky and Malynivtsi sites of the BII stage. Firstly the characteristic ornamental features of the pottery were identified. The mapping of the site to the second phase of the Mereshovka local-chronological group was justified.
Concerning the settlement of Malynivtsi the analysis of the pottery complex made it possible to trace the main features of the first phase of the Shypyntsi group and the influences of the Mereshovka ornamental traditions. As a result we managed to attribute the site to the Shypyntsi-Mereshovka contact area.
The history of the study of these monuments is described, the materials obtained are analyzed, the attention is paid to the problems and prospects of studying and preserving the monuments.
FORMATION OF THE ANTHROPOLOGICAL COMPOSITION OF THE POPULATION OF UKRAINE IN COSSACK TIME. STEPPE IMPACT
Authors: Rudych T. O.
Published: April 2021

The anthropological type of Ukrainians of Cossack Era was formed on the Old Rus anthropological substrate. They were mostly descendants of the inhabitants of former lands of Drevlyani, Volynyani, Tivertsy and partly Galichani. They were characterized by a combination of a broad face with a dolichocranial or mesocranial skull. People from non-Slavic groups, including ones from the steppe zone, also took part in the formation of the anthropological composition of the late medieval population of Ukraine. Mostly it was a population that was genetically related to the groups that had ancient roots in the Turkic-speaking world. It was characterized by a Zlivkin morphological complex (brachycranium, a relatively broad face that had a weakened horizontal profile at the top). The type is Caucasian, it was widespread in large areas occupied by the Saltovo-Mayatska culture. It was characteristic for the population of Khazaria, the medieval cities of Crimea, the plains of the North Caucasus, the southern Bulgarians. For the population of Volga Bulgaria, the appearance of this morphological complex is associated with the movement of the early Bulgarians genetically related to the Sarmatians.
The type continued to dominate in some areas during the Golden Horde and after the Golden Horde Age. Its presence is recorded in the south of Ukraine and in Moldova. The infiltration of the descendants of this population into the Slavic environment of Ukraine took place in different ways.
The source territories for it could be the Lower Dnieper and the Prut-Dniester interfluve. The time of infiltration is most likely the second half of the 13th—15th centuries. Single skulls which are characterized by a tall face with a sharp horizontal profile and can be associated with people from the North Caucasus are recorded in the late medieval cemeteries of Ukraine.
Skulls with clearly defined Mongoloid features practically are not found in the late medieval Christian cemeteries of Ukraine. Groups of nomads with these features (from Cumans to Nogai Tartars) are anthropologically differ as far as possible from the population of Cossack Era Ukraine, which was buried in Christian cemeteries.

Particular aspects of forming of legal regulation of criminal liability of officials for committing a criminal offense related to accepting an offer, promise or receiving an illegal benefit are researched. The issue of expanding the range of subjects of a criminal offense under Article 368 of the Criminal Code of Ukraine is analyzed. Experience of Criminal and Law Regulation of liability of certain categories of officials according to legislations of Austria, Norway, and Holland, Canada is analyzed. There is stressed that the analysis of the subjects of the crime under Article 368 of the Criminal Code of Ukraine and given in Note 1 to this Article allows to propose the text of the list included in Note 1 of Article 368 of the Criminal Code of Ukraine in the following wording, adding to the list of officials «Commissioner of the President of Ukraine for the Rights of the Child, Commissioner of the President of Ukraine for the Rights of Persons with Disabilities, Business Ombudsman, Chairman of the Accounting Chamber»; «Officials, in Articles 368, 3685, 369 and 382 of this Code are: 1) the President of Ukraine, … People’s Deputies of Ukraine, the Commissioner for Human Rights of the Verkhovna Rada of Ukraine, the Presidential Commissioner for Children’s Rights, the Presidential Commissioner for the Rights of Persons with Disabilities, the CMU Business Ombudsman, Chairman of the Accounting Chamber, Advisers and Assistants to the President of Ukraine, Chairman of the Verkhovna Rada of Ukraine, Prime Minister of Ukraine». There is outlined that current legislation enshrines the «duality» of the legal status of a Civil Servant. It is expressed in existence of Public Servants as a subject of Public Law, and as a private person — a subject of Private Law relations outside the performance of statutory obligations and rights. Obviously, that this legal «duality» influences on the character of Public Relations which is a subject of basic research in public administration, legal deontology, administrative and criminal law.
The Importance of Law Practice in Achieving Legal Certainty Regarding the Grounds for Disciplinary Liability of a Judge
Authors: MALASHENKOVA Tetiana
Published: April 2021

In order to overcome the relevant problem, the Law of Ukraine “On the Judiciary and the Status of Judges” significantly changed both the grounds for bringing a judge to disciplinary responsibility and the grounds for applying the most severe measure of such responsibility — dismissal of a judge. The level of detailing of such grounds is quite high, both in terms of the certainty of such grounds, and in terms of proportionality between the type of disciplinary misconduct and the type of penalty to be applied for it. At the same time, the results of the analysis of the relevant legal provisions shows that they are not devoid of evaluative, vague concepts, such as «gross disregard for the duties of a judge», «gross violation of the law», «gross negligence», «significant negative consequences». Thus, the question arises whether the problem of uncertainty of the grounds for disciplinary liability of a judge has been conceptually resolved, or whether the relevant problem continues to exist despite significant legislative detail of the relevant grounds. Resolving this issue is the purpose of this article. The existence of wording in the legislation that does not meet the requirements of legal certainty, such as «gross negligence», «gross violation of the law» carries certain risks to the independence of judges, but the existence of such risks can not be considered a reason for the law refused to use them. This is due to the objective impossibility of formulating in the law an absolutely exhaustive list of grounds for disciplinary liability in general and grounds for dismissal of a judge in particular. Critical is the issue of forming a consistent practice of the disciplinary body, which would, firstly, form the criteria for understanding vague concepts, and secondly, would not allow different approaches to responding to the same misconduct of a judge.

Published: April 2021

The paper deals with the issues on divorce with certain categories of citizens in the family law of Ukraine. Particular attention is paid to the legal and certain procedural aspects of divorce with such categories of persons as servicemen (including prisoners of war), persons sentenced to imprisonment, persons suffering from mental disorders, and persons who are temporarily out of Ukraine’s control. The purpose of the paper is to research the issue of divorce with certain categories of persons in the family law of Ukraine in order to find appropriate ways to solve problems in this field. Such scientific methods as analysis, synthesis, law and comparative analysis, and elements of content-analysis are applied in the paper. Court cases were analysed with the help of method of cases and they were used as illustration of practice of divorce with certain categories of persons. Ways of resolving of problems that have place in the researched field are suggested. In particular, it is suggested to amend the family legislation of Ukraine, which would: enshrine persons sentenced to imprisonment for a term of not less than five years, as a separate category of persons in the sense of divorce at the request of one of the spouses; it was forbidden to divorce prisoners of war until they returned from captivity. Emphasis is placed on the need to change the conceptual approach of the courts to divorce a person suffering from a mental disorder, which cannot be a basis for declaring a person incompetent. Emphasis is placed on the need to change the conceptual approach of the courts to divorce a person suffering from a mental disorder, which cannot be a basis for declaring a person incompetent. In particular, there is suggested to either create a legal basis for the courts not to take into account the circumstances of mental illness in divorce proceedings, which cannot be a ground for recognizing the incapacity of one of the parties (usually the defendant) as the dominant cause of divorce, or to turn to the actual institution of judicial precedent.

Comparative Analysis of Empathy Traits Differences in Males and Females
Authors: Encalada T. Michelle ,   Florida International University, USA
Published: April 2021

Researchers agree that one of the most important aspects of psychopathy is lack of empathy. Literature relating to psychopathy and its central components focuses on boys and men, while overlooking girls and women. This issue is partially due to the measurement tools and beliefs about sex-based expression. Previous studies focus primarily on empathy as it relates to antisocial behavior and abuse but is deficient in gender differences and antecedents. This study seeks to fill these voids by examining factors that may distinctly affect male and female empathy levels. The current study used data from the 6th wave of the National Youth Survey to examine empathy levels of 1,452 youths ranging in age from 17 – 24 years. Findings reveal that several variables have a significant impact on empathy levels. Furthermore, analysis shows that the severity of the impact differs depending upon respondent gender. This sheds light on the contrast between male and female empathy levels and invites further investigation into the factors which play a role in the developm

Published: April 2021

The reversible, weak ground-state aggregate formed by dipole–dipole interactions between an electron donor and an electron acceptor is referred to as an electron-donor–acceptor (EDA) complex. Generally, upon light irradiation, the EDA complex turns into the excited state, causing an electron transfer to give radicals and to initiate subsequent reactions. Besides light as an external energy source, reactions involving the participation of EDA complexes are mild, obviating transition metal catalysts or photosensitizers in the majority of cases and are in line with the theme of green chemistry. This review discusses the synthetic reactions concerned with EDA complexes as well as the mechanisms that have been shown over the past five years.

Published: April 2021

Introduction. Currently, COVID-19 treatment includes several options, including the use of convalescent plasma. Therefore, the presence of anti-SARS-CoV-2 in blood donors after the clinical recovery of COVID-19, depending on their place of residence, age and the clinical manifestation of the disease is of scientific-practical interest.

Material and methods. A total of 119 donors among patients were examined, namely males aged 18-60 years, having a past history of COVID-19 disease, being confirmed by PCR and treated, showing a negative PCR-based test result, which was performed at least 14 days after clinical recovery. The presence/absence of anti-SARS-CoV-2 was assessed by enzyme-linked immunosorbent assay.

Results. The obtained data showed that 87.4% of plasma donors responded to COVID-19 infection by anti-SARS-CoV-2 IgG expression, being predominantly found in the 26-35 age group. Most donors experienced mild and medium clinical forms. It is important to note that all severe clinical manifestations of the infection were followed by formation of anti-SARS-CoV-2 IgG. Urban living environment was predominantly found in convalescent donors (75.0%), which indicates that they are better informed by medical institutions.

Conclusions. The study shows that male blood donors aged 18-60 years, subsequently cured and being positive to anti-SARS-CoV-2 IgG can serve as a source of fresh plasma used for the treatment of COVID-19 patients.

The influence of land use-impacted tributaries on water quality and phytoplankton in the Mooi River, North West Province, South Africa
Authors: Koekemoer Lauralee , Janse van Vuuren Sanet , Levanets Anatoliy
Published: April 2021

Background: Effluents from agricultural activities, metal and peat mining, urban and industrial areas, informal settlements and wastewater treatment plants all influence tributaries feeding the Mooi River. All these land uses ultimately result in a deterioration of water quality in the Mooi River.Objectives: The main objective was to relate the effects of inflowing tributaries to water quality and phytoplankton assemblages in the Mooi River.Method: Physico-chemical environmental variables were compared with water quality objectives and known limits to assess general water quality in the Mooi River over a one-year period. Water quality and phytoplankton in tributarieswere compared to that at sites upstream and downstream from their inflows to determine the extent to which the tributaries affected the Mooi River. Multivariate analysis assisted in the interpretation of phytoplankton and physico-chemical data at the different sites.Results: Seven phytoplankton phyla were identified in the Mooi River. Diatoms and green algae were most dense and diverse. Cyanobacteria were responsible for various problems, especially in the Wasgoedspruit where they dominated and reached high densities. Lowest phytoplankton density and diversity were found in the upstream and downstream sections of the river, while maximum density and diversity were found during summer in the middle reaches. The inflow of tributaries, especially the Wasgoedspruit, had a pronounced effect on water quality downstream. Phytoplankton density and diversity were less affected than chemical variables, especially nutrient concentrations.Conclusion: Various land use activities surrounding the Mooi River’s tributaries contributed to a deterioration of water quality in the main stream of the Mooi River.

Authors: Shikwambana Purvance , Taylor Jonathan C. , Govender Danny , Botha Judith
Published: April 2021

Background: Although the Kruger National Park (KNP) is a protected area, it is not exempted from anthropogenically induced impacts, which often compromise river water flow and quality. Measures of river water quality in South Africa have conventionally been based on water chemistry as well as different ecological indicator groups such as fish and macroinvertebrates. Diatoms have been shown to be useful indicators of changes in water quality resulting from pollution and land-use impacts.Objectives: To determine the applicability of diatoms for hind-casting water quality in the KNP and to compare recent diatom community composition with those from the 1980s.Methods: In this study, pH and electrical conductivity (EC) were used to evaluate temporal changes in water quality of three rivers within the KNP. Additionally, we made use of historic diatom samples from three of the five perennial rivers to evaluate if diatom communities reflected changes in water conditions between 1983 and 2015.Results: Diatom community structure was significantly different between 1983 and 2015. Diatom-based index scores (SPI) indicated an improvement in water quality for the Letaba and Olifants rivers.Conclusion: Diatoms were shown to be useful indicators of current water quality and are also useful for determining temporal changes.

Background: The understanding of the impact of land-use on the dynamics of phytoplankton assemblages during varying climate conditions on rivers is limited.Objective: To determine the impact of land-use types and flow on phytoplankton assemblages in the Sabie River.Methods: The relationships between land-use patterns, water quality and phytoplankton assemblages were analysed using canonical correspondence analyses (CCA).Results: Six main land-use types could be distinguished in the eight identified sub-catchments of the river. The CCA results showed that the land-use had a stronger correlation with phytoplankton classes during the higher flow conditions than during low flow conditions. The forestry land-use type had the strongest correlation with nitrate–nitrite concentrations in the Sabie River. Chlorophyll-a concentrations were higher during 2016, and a slightly lower number of genera were observed for the class Chlorophyceae. During 2017 the number of genera of the class Cyanophyceae decreased together with chlorophyll-a and total cell concentrations.Conclusion: Low flow conditions favoured filamentous genera that are common to mesotrophic conditions while higher flow conditions favoured single-celled small genera more common to oligotrophic waters with higher disturbance. This study showed that flow has the potential to enhance the impact of land-use on phytoplankton community dynamics in a river system and thereby may have further impacts on the health and activities of surrounding communities.

The paper analyses the barbarisms and slang words used in the field of transport. It deals with the words that are attributed to the colloquial language. The basis of the work is a questionnaire. The students of the Faculty of Transport Engineering of VGTU and people working in the field of transport answered the questionnaire. The respondents were asked the following questions: “Do you use the given words?”, “Do you know the Lithuanian equivalents of the given words?”, “Does a person speaking correctly make a good impression?”. According to the results of the questionnaire, we can conclude that the respondents know the Lithuanian equivalents of the studied words quite well, but when they communicate, they give preference to barbarisms and slang words of the colloquial language. Most probably they are influenced by the environment, in which they communicate, and the traditional usage. If one or another slang word is used temporarily and then forgotten, it doesn‘t break into the native language. But if barbarisms and slang words are used too often, they become a habit, it and is hard to avoid their usage in other social surroundings.
Detecting the Figure Rotation of Dark Matter Halos with Tidal Streams

The dark matter halos that surround Milky Way–like galaxies in cosmological simulations are, to first order, triaxial. Nearly 30 yr ago it was predicted that such triaxial dark matter halos should exhibit steady figure rotation or tumbling motions for durations of several gigayears. The angular frequency of figure rotation predicted by cosmological simulations is described by a log-normal distribution of pattern speed Ω
p
with a median value 0.15 h km s−1 kpc−1 (∼0.15 h rad Gyr−1 ∼ 9° h Gyr−1) and a width of 0.83h km s−1 kpc−1. These pattern speeds are so small that they have generally been considered both unimportant and undetectable. In this work we show that even extremely slow figure rotation can significantly alter the structure of extended stellar streams produced by the tidal disruption of satellites in the Milky Way halo. We simulate the behavior of a Sagittarius-like polar tidal stream in triaxial dark matter halos with different shapes, when the halos are rotated about the three principal axes. For pattern speeds typical of cosmological halos, we demonstrate, for the first time, that a Sagittarius-like tidal stream would be altered to a degree that is detectable even with current observations. This discovery will potentially allow for a future measurement of figure rotation of the Milky Way’s dark matter halo, perhaps enabling the first evidence of this relatively unexplored prediction of cold dark matter.

We have analyzed ALMA Cycle 5 data in Band 4 toward three low-mass young stellar objects, IRAS 03235+3004 (hereafter IRAS 03235), IRAS 03245+3002 (IRAS 03245), and IRAS 03271+3013 (IRAS 03271), in the Perseus region. The HC3N (J = 16–15; E
up/k = 59.4 K) line has been detected in all of the target sources, while four CH3OH lines (E
up/k = 15.4–36.3 K) have been detected only in IRAS 03245. Sizes of the HC3N distributions (∼2930–3230 au) in IRAS 03235 and IRAS 03245 are similar to those of the carbon-chain species in the warm carbon-chain chemistry (WCCC) source L1527. The size of the CH3OH emission in IRAS 03245 is ∼1760 au, which is slightly smaller than that of HC3N in this source. We compare the CH3OH/HC3N abundance ratios observed in these sources with predictions of chemical models. We confirm that the observed ratio in IRAS 03245 agrees with the modeled values at temperatures around 30–35 K, which supports the HC3N formation by the WCCC mechanism. In this temperature range, CH3OH does not thermally desorb from dust grains. Nonthermal desorption mechanisms or gas-phase formation of CH3OH seem to work efficiently around IRAS 03245. The fact that IRAS 03245 has the highest bolometric luminosity among the target sources seems to support these mechanisms, in particular the nonthermal desorption mechanisms.
Anomalous Proton Velocity Diffusion by Quasi-monochromatic Kinetic Alfvén Waves

The anomalous diffusion of resonant protons in parallel and perpendicular velocity space by kinetic Alfvén waves is discussed. The velocity diffusion coefficient is calculated by employing an autocorrelation function for proton trajectories. It is found that for protons resonant with the waves, the perpendicular diffusion coefficient decays away for a sufficiently long time, but parallel diffusion monotonically increases in time until it saturates at a certain level. This result indicates that a portion of resonant protons can undergo anomalous diffusion along the background magnetic field even if the intensity of the kinetic Alfvén wave is sufficiently low. The present findings imply that under suitable conditions, astrophysical charged-particle acceleration can take place in the parallel direction.
Dalek: A Deep Learning Emulator for TARDIS

Supernova spectral time series contain a wealth of information about the progenitor and explosion process of these energetic events. The modeling of these data requires the exploration of very high dimensional posterior probabilities with expensive radiative transfer codes. Even modest parameterizations of supernovae contain more than 10 parameters and a detailed exploration demands at least several million function evaluations. Physically realistic models require at least tens of CPU minutes per evaluation putting a detailed reconstruction of the explosion out of reach of traditional methodology. The advent of widely available libraries for the training of neural networks combined with their ability to approximate almost arbitrary functions with high precision allows for a new approach to this problem. Instead of evaluating the radiative transfer model itself, one can build a neural network proxy trained on the simulations but evaluating orders of magnitude faster. Such a framework is called an emulator or surrogate model. In this work, we present an emulator for the tardis supernova radiative transfer code applied to Type Ia supernova spectra. We show that we can train an emulator for this problem given a modest training set of 100,000 spectra (easily calculable on modern supercomputers). The results show an accuracy on the percent level (that are dominated by the Monte Carlo nature of tardis and not the emulator) with a speedup of several orders of magnitude. This method has a much broader set of applications and is not limited to the presented problem.
