Searching for ZZ Ceti White Dwarfs in the Gaia Survey
Authors: Vincent Olivier , Bergeron P. , Lafrenière David
Published: November 2020

The Gaia satellite recently released parallax measurements for ∼260,000 high-confidence white dwarf candidates, allowing for precise measurements of their physical parameters. By combining these parallaxes with Pan-STARRS and u-band photometry, we measured the effective temperature and stellar mass for all white dwarfs in the Northern Hemisphere within 100 pc of the Sun, and identified a sample of ZZ Ceti white dwarf candidates within the so-called instability strip. We acquired high-speed photometric observations for 90 candidates using the PESTO camera attached to the 1.6 m telescope at the Mont-Mégantic Observatory. We report the discovery of 38 new ZZ Ceti stars, including two very rare ultramassive pulsators. We also identified five possibly variable stars within the strip, in addition to 47 objects that do not appear to show any photometric variability. However, several of those could be variable with an amplitude below our detection threshold, or could be located outside the instability strip due to errors in their photometric parameters. In the light of our results, we explore the trends of the dominant period and amplitude in the M–

plane, and briefly discuss the question of the purity of the ZZ Ceti instability strip (i.e., a region devoid of non-variable stars).
Defining the (Black Hole)–Spheroid Connection with the Discovery of Morphology-dependent Substructure in the MBH–nsph and MBH–Re,sph Diagrams: New Tests for Advanced Theories and Realistic Simulations

Published: November 2020

For 123 local galaxies with directly measured black hole masses (M
BH), we provide the host spheroid’s Sérsic index (n
sph), effective half-light radius (R
e,sph), and effective surface brightness (

), obtained from careful multicomponent decompositions, and we use these to derive the morphology-dependent M
BH–n
sph and M
BH–R
e,sph relations. We additionally present the morphology-dependent M
*,sph–n
sph and M
*,sph–R
e,sph relations. We explored differences due to early-type galaxies (ETGs) versus late-type galaxies (LTGs), Sérsic versus core-Sérsic galaxies, barred versus non-barred galaxies, and galaxies with and without a stellar disk. We detect two different M
BH–n
sph relations due to ETGs and LTGs with power-law slopes 3.95 ± 0.34 and 2.85 ± 0.31. We additionally quantified the correlation between M
BH and the spheroid’s central concentration index, which varies monotonically with the Sérsic index. Furthermore, we observe a single, near-linear M
*,sph–

relation for ETGs and LTGs, which encompasses both classical and alleged pseudobulges. In contrast, ETGs and LTGs define two distinct M
BH–R
e,sph relations with

(cf. ∼0.51 dex for the M
BH–σ relation and ∼0.58 dex for the M
BH–M
*,sph relation), and the ETGs alone define two steeper M
BH–R
e,sph relations, offset by ∼1 dex in the

direction, depending on whether they have a disk or not and explaining their similar offset in the M
BH–M
*,sph diagram. This trend holds using 10%, 50%, or 90% radii. These relations offer pivotal checks for simulations trying to reproduce realistic galaxies, and for theoretical studies investigating the dependence of black hole mass on basic spheroid properties.
The μ Tau Association: A 60 Myr Old Coeval Group at 150 pc from the Sun
Authors: Gagné Jonathan , David Trevor J. , Mamajek Eric E. , Mann Andrew W. , Faherty Jacqueline K. , Bédard Antoine
Published: November 2020

We present an analysis of the newly identified μ Tau Association (MUTA) of young stars at ≃150 pc from the Sun that is part of the large Cas-Tau structure, coeval and comoving with the α Persei cluster. This association is also located in the vicinity of the Taurus-Auriga star-forming region and the Pleiades association, although it is unrelated to them. We identify more than 500 candidate members of MUTA using Gaia DR2 data and the BANYAN Σ tool, and we determine an age of 62 ± 7 Myr for its population based on an empirical comparison of its color–magnitude diagram sequence with those of other nearby young associations. The MUTA association is related to the Theia 160 group of Kounkel & Covey and corresponds to the e Tau group of Liu et al. It is also part of the Cas-Tau group of Blaauw. As part of this analysis, we introduce an iterative method based on spectral templates to perform an accurate correction of interstellar extinction of Gaia DR2 photometry, needed because of its wide photometric bandpasses. We show that the members of MUTA display an expected increased rate of stellar activity and faster rotation rates compared with older stars, and that literature measurements of the lithium equivalent width of nine G0- to K3-type members are consistent with our age determination. We show that the present-day mass function of MUTA is consistent with other known nearby young associations. We identify WD 0340+103 as a hot, massive white dwarf remnant of a B2 member that left its planetary nebula phase only 270,000 yr ago, posing an independent age constraint of

Myr for MUTA, consistent with our isochrone age. This relatively large collection of comoving young stars near the Sun indicates that more work is required to unveil the full kinematic structure of the complex of young stars surrounding α Persei and Cas-Tau.
Spatially Resolved Study of Recombining Plasma in W49B Using XMM-Newton
Authors: Holland-Ashford Tyler , Lopez Laura A. , Auchettl Katie
Published: November 2020

W49B is the youngest supernova remnant (SNR) to date that exhibits recombining plasma. The two prevailing theories of this overionization are rapid cooling via adiabatic expansion or through thermal conduction with an adjacent cooler medium. To constrain the origin of the recombining plasma in W49B, we perform a spatially resolved spectroscopic study of deep XMM-Newton data across 46 regions. We adopt a three-component model (with one interstellar medium and two ejecta components), and we find that recombining plasma is present throughout the entire SNR, with increasing overionization from east to west. The latter result is consistent with previous studies, and we attribute the overionization in the west to adiabatic expansion. However, our findings depart from these prior works, as we find evidence of overionization in the east as well. As the SNR is interacting with molecular material there, we investigate the plausibility of thermal conduction as the origin of the rapid cooling. Based on estimated timescales, we show that both large- and small-scale thermal conduction can explain the observed overionization of the hotter ejecta. However, overionization of the cooler ejecta is only possible through small-scale thermal conduction resulting in evaporation of embedded, dense clouds with sizes ≲1 pc.

Cold quasars are a rare subpopulation observed to host unobscured, X-ray luminous active galactic nuclei (AGN) while also retaining a cold gas supply fueling high star formation rates. These objects are interpreted as AGN early in their evolution. We present new SOFIA HAWC+ far-infrared observations, far-ultraviolet to far-infrared (FUV–FIR) photometry, and optical spectroscopy to characterize the accretion and star formation behavior in a cold quasar at z ∼ 0.405 (CQ 4479). CQ 4479 is a starburst galaxy with a predominantly young stellar population and a high gas mass fraction of ∼50%–70%. The AGN component has yet to become the dominant component of the FIR emission. We also find AGN bolometric luminosity that varies as a function of observation method and AGN region probed. Finally, we identify a candidate outflow feature corroborating the hypothesis that cold quasars have energetic feedback. This object presents an intriguing look into the early stages of AGN feedback and probes the rare phase where an AGN and cold gaseous component coexist.
Non-Markovian Pitch-angle Scattering as the Origin of Particle Superdiffusion Parallel to the Magnetic Field
Authors: Zimbardo Gaetano , Perri Silvia
Published: November 2020

We develop a theoretical model for particle superdiffusive transport parallel to the average magnetic field, due to the pitch-angle scattering times having a non-Markovian, power-law probability distribution. We show that a non-Markovian Fokker–Planck equation can be derived, where the traditional time derivative is changed for a fractional time derivative. By solving the fractional Fokker–Planck equation, with the time-dependent part having solutions that are expressed by the Mittag-Leffler functions, it is found that an initial pitch-angle distribution slowly decays toward isotropy. This leads to a parallel velocity autocorrelation function that also has a slow power-law decay in time, thus implying superdiffusive transport in the direction parallel to the background magnetic field. In this framework, we derive for the first time the anomalous diffusion coefficient as a function of physical parameters like the background magnetic field, the resonant turbulence level, and the particle speed.
Prediction of the In Situ Coronal Mass Ejection Rate for Solar Cycle 25: Implications for Parker Solar Probe In Situ Observations

Published: November 2020

The Parker Solar Probe (PSP) and Solar Orbiter missions are designed to make groundbreaking observations of the Sun and interplanetary space within this decade. We show that a particularly interesting in situ observation of an interplanetary coronal mass ejection (ICME) by PSP may arise during close solar flybys (<0.1 au). During these times, the same magnetic flux rope inside an ICME could be observed in situ by PSP twice, by impacting its frontal part as well as its leg. Investigating the odds of this situation, we forecast the ICME rate in solar cycle 25 based on two models for the sunspot number (SSN): (1) the forecast of an expert panel in 2019 (maximum SSN = 115), and (2) a prediction by McIntosh et al. (2020, maximum SSN = 232). We link the SSN to the observed ICME rates in solar cycles 23 and 24 with the Richardson and Cane list and our own ICME catalog, and calculate that between one and seven ICMEs will be observed by PSP at heliocentric distances <0.1 au until 2025, including 1σ uncertainties. We then model the potential flux rope signatures of such a double-crossing event with the semiempirical 3DCORE flux rope model, showing a telltale elevation of the radial magnetic field component B

normal to the solar equator compared to field rotation in the first encounter. This holds considerable promise to determine the structure of CMEs close to their origin in the solar corona.
Universal at Last? The Splashback Mass Function of Dark Matter Halos
Authors: Diemer Benedikt
Published: November 2020

The mass function of dark matter halos is one of the most fundamental statistics in structure formation. Many theoretical models (such as Press–Schechter theory) are based on the notion that it could be universal, meaning independent of redshift and cosmology, when expressed in the appropriate variables. However, simulations exhibit persistent nonuniversalities in the mass functions of the virial mass and other commonly used spherical overdensity definitions. We systematically study the universality of mass functions over a wide range of mass definitions, for the first time including the recently proposed splashback mass,

. We confirm that, in ΛCDM cosmologies, all mass definitions exhibit varying levels of nonuniversality that increase with peak height and reach between 20% and 500% at the highest masses we can test.

,

, and

exhibit similar levels of nonuniversality. There are, however, two regimes where the splashback mass functions are significantly more universal. First, they are universal to 10% at

, whereas spherical overdensity definitions experience an evolution due to dark energy. Second, when additionally considering self-similar cosmologies with extreme power spectra, splashback mass functions are remarkably universal (to between 40% and 60%), whereas their spherical overdensity counterparts reach nonuniversalities between 180% and 450%. These results strongly support the notion that the splashback radius is a physically motivated definition of the halo boundary. We present a simple and universal fitting formula for splashback mass functions that accurately reproduces our simulation data.

New data on the fauna of Heteroceridae (Coleoptera) of the Republic of Khakassia (Eastern Siberia)
Authors: Sazhnev Alexey S. , Dragan Sergey V.
Published: November 2020

The recent status of the family Heteroceridae in Siberia is discussed and the main references are given. From ten species of the Heteroceridae, which have been reported for the fauna of Siberia, only one species Heterocerus parallelus Gebler, 1830 was previously recorded in southern Khakassia. Here we presented six species from two genera of the family Heteroceridae (Coleoptera), which we collected in the Republic of Khakassia (Eastern Siberia, Russia). We recorded five species (Augyles interspidulus (Charpentier, 1979), Heterocerus fenestratus (Thunberg, 1784), H. fossor Kiesenwetter, 1843, H. fusculus Kiesenwetter, 1843, and H. obsoletus Curtis, 1828) in Khakassia for the first time. We collected the material in Abakan River valley (Abakan city) using an ultraviolet lamps in 2018–2019. We used BLB-T5/4W Ultraviolet Black Light Bulb with 2–3 hours of exposure from May 27 to October 13, 2018 and FLU10 T8 G13/18W with 2–13 hours of exposure from March 31 to October 10, 2019. Second author collected the majority of examined specimens; all specimens are deposited in collection of the Papanin Institute for Biology of Inland Waters of the Russian Academy of Sciences.

Authors: Olonova Marina V. , Vedernikova Anna S. , Albtight Thomas
Published: November 2020

Brunnera sibirica is a Southern-Siberian endemic herb. Being a Pliocene relict, it is included in Red Data Books of many Siberian regions. The aim of our study was to identify the climatic niche and territories suitable for this vulnerable species using the MaxEnt method. The climatic profile of B. sibirica was constructed using the BIOCLIM method with 19 bioclimatic variables. The research has revealed that the climatic conditions in the most of Siberian territory are not suitable for the growth of B. sibirica, which confirms its relic origin in the south of Siberia.

One troglophilic species, Improphantes improbulus (Simon, 1929) is recorded from Siberia and the Altai Mountains for the first time and another troglophile species, Metellina merianae (Scopoli, 1763) is recorded from the Novosibirsk Oblast for the first time. Improphantes improbulus, a species new to Siberia, is illustrated. The distribution and habitat preferences of all six species is discussed.
Codes of new generation for safety justification of power units with a closed nuclear fuel cycle developed for the “PRORYV” project
Authors: Bolshov Leonid A. , Strizhov Valery F. , Mosunova Nastasya A.
Published: November 2020

The article describes the status of development of codes of new generation for the “PRORYV” Project by the end of 2019: twenty-five commercial-grade software products to justify design solutions and safety of power units with fast neutron reactors and liquid metal coolant (sodium and lead) in a closed nuclear fuel cycle. The developed system of codes is multi-physical and multi-scale that allows performing both calculations of the whole installations and high precision calculations of their individual elements. The developed codes offer unique features. Twelve developed codes have already been certified by Rostechnadzor, and six more have been submitted for certification. In addition to creating the software products, a large-scale work is being carried out to conduct experimental studies for code validation that meet modern requirements imposed by the codes: unique measurement techniques have been created; experimental data on flow characteristics of heavy liquid metal coolant (HLMC) in a fuel assembly simulator have been obtained, as well as of “gas-HLMC” interphase interaction after inert gas injection in HLMC and characteristics of heat exchange between the inert gas and HLMC. The results are already used for validation of system and CFD codes used in the “PRORYV” Project.

The herbarium collections are sub-collections of the Finnish Museum of Natural History Luomus that manages national natural history collections, as referred to in the Universities Act. The general collections policy defines the overall principles and guidelines concerning the collections practices. The sub-collections policies specify its guidelines and instructions, considering the special nature of the sub-collections. The policy for the botanical and mycological herbarium collections guides the activities related to all botanical, mycological and phycological collections in herbaria, hence excluding digital collections, DNA and tissue samples as well as living collections, which have separate policies. The herbarium collections policy defines and outlines the purpose of the collections as is to accrue and preserve natural specimens representing biodiversity for research and university-level teaching. The policy defines the objectives and content of related activities, the division of responsibilities for the administration and care of the collections within the organisation, and the general principles and practices for the acquisition, preservation, availability and use of the collections.
Input-to-state stability in the meaning of switching for delayed feedback switched stochastic financial system
Authors: Rao Ruofeng , Li Xiaodi
Published: November 2020

Financial system is essentially chaotic and unstable if there is not any external inputs. By means of Lyapunov function method, design of switching law, novel fuzzy assumption, $L^p$ estimation technique and Laplace semigroup theory, the author presents the boundedness and LMI-based (globally) asymptotical input-to-state stability criteria of financial systems. Particularly, the globally asymptotical stability in the meaning of switching implies that when the time $t$ is big enough, the dynamic of any subsystem must approach its unique equilibrium point. Besides, the global stability in the classical sense is not applicable to eruption of the periodical financial crisis. So the stability in the meaning of switching proposed in this paper is suitable and appropriate. Numerical examples illuminate the effectiveness of the obtained results.

À partir d’une analyse des dynamiques des services avancés dans l’économie bruxelloise, comptant pour plus d’un tiers de la valeur ajoutée totale de la RBC, cet article s’interroge sur l’impératif d’attractivité internationale qui accompagne le développement de ces services. Trois réflexions sont développées dans ce cadre. D’abord, partant du constat du caractère très international de l’économie bruxelloise, on propose de s’interroger sur la nécessité et la possibilité de renforcer l’économie internationale liée aux services avancés. Ensuite, une réflexion est menée sur les concurrences entre le centre et les périphéries dans les services avancés. Enfin, une analyse critique de l’impact social de cette économie est proposée, soulignant notamment le caractère peu créateur d’emplois de ces activités.

Published: November 2020

Op basis van een analyse van de dynamieken van de geavanceerde diensten in de Brusselse economie, goed voor meer dan een derde van de totale toegevoegde waarde van het Brussels Gewest, onderzoekt dit artikel de noodzaak van internationale aantrekkelijkheid die gepaard gaat met de ontwikkeling van deze diensten. In dat kader belichten de auteurs drie punten van overweging. Eerst en vooral staan ze, gezien het zeer internationale karakter van de Brusselse economie, stil bij de noodzaak en de mogelijkheid om de internationale economie die gekoppeld is aan de geavanceerde diensten te versterken. Vervolgens gaan ze dieper in op de concurrentie tussen het centrum en de rand in de sector van de geavanceerde diensten. Tot slot reiken ze een kritische analyse van de sociale impact van deze economie aan, waarbij ze vooral benadrukken dat deze activiteiten weinig arbeidsplaatsen creëren.

Riset Kesehatan Dasar Indonesia menyatakan perawatan penyakit ginjal menjadi beban kedua tertinggi pembiayaan BPJS. Penganti fungsi ginjal yang umum dilakukan adalah hemodialisis (HD) sehingga akses vaskular menjadi hal penting dalam penanganan GGT. Fistula arteriovena (AVF) radiosefalika merupakan pilihan akses HD yang utama. Respon endotel merupakan aspek penting dari remodeling pembuluh darah yang diperlukan untuk keberhasilan AVF. C-Reactive Protein (CRP) yang bersirkulasi tinggi dapat menyebabkan disfungsi endotel sehingga diduga memiliki nilai prediksi terhadap maturasi AVF.

Metode. Desain analitik menggunakan metode kohort prospektif dengan consecutive sampling untuk  menilai bagaimana pengaruh kadar CRP serum preoperatif terhadap maturasi AVF. Sampel diambil dari pasien GGT yang datang ke poliklinik Bedah RSUP Hasan Sadikin dan RSKG Ny.R.A.Habibie Bandung yang akan menjalani operasi AVF radiosefalika. Tes statistik menggunakan uji univariat untuk  dekskripsi data. Perbedaan kadar CRP serum preoperatif berdasarkan perbedaan status maturasi AVF dianalisis melalui perbandingan kadar CRP serum preoperatif antar kelompok maturasi AVF melalui model bivariat uji t independen.

Development of Translator Competences as the Main Task of Translator Trainers
Authors:   Dobrolyubov State Linguistics University, Ivanov Andrey , Sdobnikov Vadim ,   Dobrolyubov State Linguistics University
Published: November 2020

The article discusses development of translator competences as the main task of translator trainers. Based on the accepted definition of the notion of “competence” and the modern reali-ty of the profession, the authors propose a model of professional translator competence as the general ability to perform translation/interpreting which includes specific competences: com-municative competence, linguistic competence, textual competence, technological competence, socio-cultural competence, instrumental competence, theoretical competence, and ethical competence. The authors argue that all specific competences are interconnected, and their combination determines the character of the professional personality of a translator / interpreter.
On the History of Studying Modal Verbs in the German Language
Authors:   Lomonosov Moscow State University, Leontyeva Varvara
Published: November 2020

The article is an overview and a summary of the study of modal verbs in the German language in Russian and foreign linguistics, from Antiquity to the present day, in line with the holistic study of modality in world linguistics. Using the methods of generalization and systematization, the author analyzes monographs and articles by Russian and foreign experts in the field of the history of the German language, functional grammar, and morphology. While a considerable number of works by foreign and Russian linguists in the 20th century are devoted to the issues of semantics of preterite-present and modal verbs in specific historical periods of the development of the German language, there are still many open questions in this area. Throughout almost the entire 20th century, Germanists viewed modal verbs mainly as a means of expressing internal modality, i.e., the attitude of the speaker to the action being performed. However, in the late 20th and early 21st century, they began to actively study the subjective use of modal verbs. Much modern literature on the subject is devoted to the study of German modal verbs in the function of subjective (epistemic) modality. This article focuses on etymological, semantic, grammatical, and functional features of modal verbs in modern German and discusses a number of controversial issues, such as the question of whether modal verbs are a closed or open cluster of vocabulary, that is, whether it is possible, at the present stage of language history, to include other linguistic units into the category of modal units, it these other units answer certain semantic or grammatical criteria. It is also open to discussion whether there is a one-to-one corre-spondence between a modal verb and the type of modal relations that is expressed with the help of this verb in speech, and vice versa. The author highlights such significant aspects as grammaticalization of modal verbs, correlation of modal verbs with various types of modal relations, primary and secondary meanings of modal verbs, characteristics of the preterito-presentia, compatibility of modal verbs, and syntactic features of their usage. The relevance of this study lies in the fact that it gives a more comprehensive understanding of functions and pragmatics of modal verbs as a special lexical cluster in speech.

The main purpose of the study is to present a systematizing critical review of the existing literature on the functions of argot and to describe the characteristic features of borrowed argotisms found in Russian literary texts as well as Russian explanatory, etymological, and foreign word dictionaries. The author uses the methods of description and comparison, the comparative method, and the opposition method. Since the general criminal argot, the specialized argot, and the prison argot are rich in their forms and functionality, they perform a number of important tasks, and gradually pene-trate into literary speech. Thus a careful study of their functions helps to explain some of the linguistic realities of the modern Russian language and throws a fresh light on the psychology of native Russian speakers. After analyzing a diverse body of sources, the author identifies sixteen separate functions of borrowed words that are common for the general, specialized, and prison argot, namely: service, secret, identification, nominative, worldview, expressive, utilitarian, communicative, signaling, magic, pseudo-aesthetic, agitation, and game function as well as the function of gender determinism, the function of intimidation, and, finally the function of stylistic characterization of literary characters through their speech. The results of the research can be used in college-level courses of modern Russian for law and language students, in special courses in social linguistics and cultural studies as well as in language and public speaking courses in schools and universities.

The purpose of this study was to investigate work family experiences of workaholic women with moderation effect of family support through underpinning conservation of resources theory (COR) in banking sector of Pakistan. Total sample size was 110. The Smart PLS version 3.2.8 was used to assess the structural model measurement. Structural model measurement comprised of Path co-efficient (R2) within the limit whereas the P values for workaholism and work family conflict is significant. Similarly, the moderation effect of family support also significant and hence both hypotheses were accepted. The model shows adequate predicative accuracy (Q2) within the threshold value. The study has implication for the banking sector in Pakistan to understand that their workaholic behavior is a productive and valuable phenomenon that needs to be rewarded and addressed ethically and negative outcome can be neutralized through social intervention like family support. However, the future study needs to explore other specific work-related social support as moderation on work family conflict with large sample size and different context.

Hypotheses tested using exploratory analysis and GMM panel regression applied to the data obtained from 26 commercial banks of two countries for the period FY2008 to FY2017. The results reveal a significant connection between advancing approach and loan loss provisions for banks of both countries. Further, the advancing approach establishes a meaningful adverse relationship with profitability and credit risk for banks in Pakistan and with CAR for banks in Bahrain. Overall, the study discovers loan loss provision, profitability, credit risk, and CAR as critical factors having a direct and indirect influence on banks’ advancing approaches, which is an addition to the body of knowledge. Interestingly, it observed that the banks are more inclined towards risky assets such as consumer finance must maintain a higher degree of capital adequacy ratio.

This study's objective is to determine the impact of two types of ownership of a company (managerial ownership and institutional ownership) on its stock price crash risk. To examine whether a firm's ownership structures have an association with stock price crash risk, the multiple linear regression model applied on the panel data of 190 companies listed on KSE for the year 2009-2018. The results of this study show that there is a significantly positive relationship between the institutional ownership and stock price crash risk. However, no association found between managerial ownership and price crash risk. These results imply that the percentage of institutional ownership should be reduced in the firm's ownership structure to reduce the firm's stock price crash risk.
