It is often necessary to assess the parameters of fire development taking into account the influence of fire protection systems by making the regulatory fire-technical expertise. It may also be necessary to carry out an expert examination of the technical solutions adopted at the site for their compliance with fire safety requirements. These practical studies, in particular, are necessary to analyse the consequences of fire safety violations and establish causal links between violations of requirements and the consequences of fire, both past and theoretically possible. A modern way to estimate fire parameters is by field modeling. Field modeling of fire dynamics can be used to answer questions in two expert situations: after fire and before fire (in particular, within the framework of supervisory measures). When making fire-technical expertise on the fire occurred, the expert needs to restore the pre-fire situation and model the real fire dynamics taking into account the established fire information contained in the case file. In a situation before a fire, the expert needs to model a potentially possible fire under the most unfavourable conditions. In accordance with fire safety requirements, each object of protection must have a fire safety system aimed at preventing fire, ensuring the safety of people and property in case of fire. Compliance of design values and characteristics of the building or structure with safety requirements shall be justified by calculations or tests performed according to certified technique. On the basis of the analysis of the regulatory framework and the formulated groups of regulatory questions there have been developed the procedure of the expert‘s actions and the algorithm for simulating fire dynamics when answering questions related to automatic fire alarm. The impact of input data on the possibility of forming categorical or probabilistic outputs was evaluated. The proposed detailed algorithm of field simulation of fire dynamics during the regulatory fire-technical examination is drawn up taking into account possible calculated errors and obtaining ambiguous results.

The main directions of FPS GPS divisions development in the Arctic zone of the Russian Federation (AZRF) are formulated. The paper draws attention to the problem of equipping fire and rescue units operating in the AZRF with special equipment adapted to extreme operating conditions. A number of factors have a negative impact on providing fire and rescue units with the necessary equipment. They include an insufficient number of equipment types designed specifically for operation in AZRF conditions, the lack of a regulatory framework containing the requirements to certain types of fire and rescue equipment of HL climatic performance. In addition, the authorizing departmental documents, defining the order of material and technical support of divisions of FPS GPS EMERCOM of Russia, do not consider the features of material and technical support of divisions in AZRF. There are formulated the following main development priorities for the system of material and technical support of forces and means of the FPS GPS EMERCOM of Russia in AZRF: development and implementation of innovative models of multifunctional mobile fire and rescue vehicles and equipment, improvement of the system of maintenance and repair for fire and rescue equipment and vehicles in the Arctic zone. In addition, it is necessary to build, reconstruct and equip the infrastructure objects for divisions of FPS GPS EMERCOM of Russia including the provision with modern information and communication technologies and life-support systems that allow to monitor the situation effectively and, if necessary, to warn the population.

Published: June 2020

Abstract
Interplanetary coronal mass ejections (ICMEs) are eruptions of plasma that propagate outward through the heliosphere. ICMEs, and the shocks they drive, cause a sudden decrease in the cosmic-ray flux in their local area of the heliosphere, called a Forbush decrease (FD). A method of defining FDs is established, and an automated process for identifying FDs in neutron monitor (NM) data is created. The correlation between ICME properties and FD magnitude in 12 different NMs is examined for 91 ICME-associated FD events occurring from 2001 through 2019 August. A number of ICME properties show positive correlation with FD magnitude, with decreasing correlation strength as NM cutoff rigidity increases.

Published: June 2020

Abstract
We present sensitive and high angular-resolution (∼0.″2–0.″3) (sub)millimeter (230 and 345 GHz) continuum and CO(2−1)/CO(3−2) line archive observations of the disk star system in UX Tauri carried out with the Atacama Large Millimeter/Submillimeter Array. These observations reveal the gas and dusty disk surrounding the young star UX Tauri A with a large signal-to-noise ratio (>400 in the continuum and >50 in the line), and for the first time we detect the molecular gas emission associated with the disk of UX Tauri C (with a size for the disk of <56 au). No (sub)millimeter continuum emission is detected at the 5σ level (0.2 mJy at 0.85 mm) associated with UX Tauri C. For the component UX Tauri C, we estimate a dust disk mass of ≤0.05 M
⊕. Additionally, we report a strong tidal disk interaction between both disks, UX Tauri A/C, separated 360 au in projected distance. The CO line observations reveal marked spiral arms in the disk of UX Tauri A and an extended redshifted stream of gas associated with the UX Tauri C disk. No spiral arms are observed in the dust continuum emission of UX Tauri A. Assuming a Keplerian rotation we estimate the enclosed masses (disk+star) from their radial velocities in 1.4 ± 0.6 M
⊙ for UX Tauri A, and 70 ± 30/sin i Jupiter masses for UX Tauri C (the latter coincides with the mass upper limit value for a brown dwarf). The observational evidence presented here lead us to propose that UX Tauri C has a close approach of a possible wide, evolving, and eccentric orbit around the disk of UX Tauri A, causing the formation of spiral arms and a stream of molecular gas falling toward UX Tauri C.
Rotation, Convective Core Overshooting, and Period Changes in Classical Cepheid Stellar Evolution Models

Abstract
Classical Cepheids are powerful probes of both stellar evolution and near-field cosmology thanks to their great luminosities, pulsations, and their adherence to the Leavitt (period–luminosity) Law. However, there still exist a number of questions regarding their evolution, such as the roles of rotation, convective core overshooting, and winds. ln particular, how do these processes impact Cepheid evolution and the predicted fundamental properties such as stellar mass? In this work, we compare a sample of Cepheids with measured rates of period change with new evolution models to test the impact of these first two processes. In our previous study we found that enhanced mass loss is crucial for describing the sample, and here we continue that analysis but for rotational mixing and core overshooting. We show that while rotation is important for stellar evolution studies, rotation itself is insufficient to model the distribution of period change rates from the observed sample. On the other hand, convective core overshooting is needed to explain the magnitude of the rates of period change, but does not explain the number of stars with positive and negative period change rates. In conclusion, we determine that convective core overshooting and stellar rotation alone are not enough to account for the observed distribution of Cepheid rates of period change and another mechanism, such as pulsation-driven mass loss, may be required.

Abstract
We present results of continuum and spectral line observations with Atacama Large Millimeter/submillimeter Array (ALMA) and 22 GHz water (H2O) maser observations using the KVN (Korean VLBI Network) and VERA (VLBI Exploration of Radio Astrometry) array (KaVA) toward a high-mass star-forming region, G25.82–0.17. Multiple 1.3 mm continuum sources are revealed, indicating the presence of young stellar objects (YSOs) at different evolutionary stages, namely an ultracompact H ii region, G25.82–E, a high-mass young stellar object (HM-YSO), G25.82–W1, and starless cores, G25.82–W2 and G25.82–W3. Two SiO outflows, at N–S and SE–NW orientations, are identified. The CH3OH 8−1–70 E line, known to be a Class I CH3OH maser at 229 GHz, is also detected, showing a mixture of thermal and maser emission. Moreover, the H2O masers are distributed in a region ∼0.″25 shifted from G25.82–W1. The CH3OH 224–215 E line shows a compact ringlike structure at the position of G25.82–W1 with a velocity gradient, indicating a rotating disk or envelope. Assuming Keplerian rotation, the dynamical mass of G25.82–W1 is estimated to be >25 M
⊙ and the total mass of 20–84 M
⊙ is derived from the 1.3 mm continuum emission. The driving source of the N–S SiO outflow is G25.82–W1 while that of the SE–NW SiO outflow is uncertain. Detection of multiple high-mass starless/protostellar cores and candidates without low-mass cores implies that HM-YSOs could form in individual high-mass cores as predicted by the turbulent core accretion model. If this is the case, the high-mass star formation process in G25.82 would be consistent with a scaled-up version of low-mass star formation.

Abstract
We use nine years of γ-ray data provided by the Fermi Large Area Telescope (LAT) to systematically study the light curves (LCs) of more than 2000 active galactic nuclei (AGN) included in recent Fermi-LAT catalogs. Ten different techniques are used, which are organized in an automatic periodicity-search pipeline, in order to search for evidence of periodic emission in γ rays. Understanding the processes behind this puzzling phenomenon will provide a better view about the astrophysical nature of these extragalactic sources. However, the observation of temporal patterns in γ-ray LCs of AGN is still challenging. Despite the fact that there have been efforts to characterize the temporal emission of some individual sources, a systematic search for periodicities by means of a full likelihood analysis applied to large samples of sources was missing. Our analysis finds 11 AGN, of which 9 are identified for the first time, showing periodicity at more than 4σ in at least four algorithms. These findings will help in solving questions related to the astrophysical origin of this periodic behavior.

Abstract
Observing the circumgalactic medium (CGM) in emission provides 3D maps of the spatial and kinematic extent of the gas that fuels galaxies and receives their feedback. We present mock emission-line maps of highly resolved CGM gas from the Figuring Out Gas & Galaxies in Enzo (FOGGIE) project and link these maps back to physical and spatial properties of the gas. In particular, we examine the ionization source leading to most O vi emission and how resolution affects the physical properties of the gas generating the emission. Finally, when increasing the spatial resolution alone, the total luminosity of the line emission increases by an order of magnitude for some lines considered. Current integral field unit instruments like Keck Cosmic Web Imager and Multi Unit Spectroscopic Explorer should be able to detect the brightest knots and filaments of such emission, and use this to infer the bulk kinematics of the CGM gas with respect to the galaxy. We conclude that the spatial resolution of simulated CGM gas can significantly influence the distribution of gas temperatures, densities, and metallicities that contribute to a given observable region. Greater spatial resolution than has been typically included in cosmological simulations to date is needed to properly interpret observations in terms of the underlying gas structure driving emission.
X-Ray Emission Evolution of the Galactic Ultraluminous X-Ray Pulsar Swift J0243.6+6124 during the 2017–2018 Outburst Observed by the MAXI GSC

Abstract
This paper reports on the X-ray emission evolution of the ultraluminous Galactic X-ray pulsar Swift J0243.6+6124 during the giant outburst from 2017 October to 2018 January as observed by the MAXI GSC all-sky survey. The 2–30 keV light curve and the energy spectra confirm the source luminosity L
X assuming an isotropic emission reached 2.5 × 1039 erg s−1, 10 times higher than the Eddington limit for a 1.4 M
⊙ neutron star. When the source was luminous with L
X ≳ 0. 9 × 1038 erg s−1, it generally exhibited a negative correlation on a hardness-intensity diagram. However, two hardness ratios, a soft color (=4–10 keV/2–4 keV) and a hard color (=10–20 keV/4–10 keV), showed somewhat different behavior across a characteristic luminosity of L
c ≃ 5 × 1038 erg s−1. The soft color changed more than the hard color when L
X < L
c, whereas the opposite was observed above L
c. The spectral change above L
c was represented by a broad enhanced feature at ∼6 keV on top of the canonical cutoff power-law continuum. The pulse profiles, derived daily, made the transition from a single-peak to a double-peak as the source brightened across L
c. These spectral and pulse-shape properties can be interpreted by a scenario in which the accretion columns on the neutron-star surface, producing the Comptonized X-ray emission, gradually became taller as L
X increases. The broad 6 keV enhancement could be a result of cyclotron-resonance absorption at ∼10 keV, corresponding to a surface magnetic field B
s ≃ 1.1 × 1012 G. The spin-frequency derivatives calculated with the Fermi GBM data showed a smooth positive correlation with L
X up to the outburst peak, and its linear coefficient is comparable to those of typical Be binary pulsars whose B
s are (1–8) × 1012 G. These results suggest that the B
s of Swift J0243.6+6124 is a few times 1012 G.

Abstract
Low surface brightness galaxies (LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies are useful for the study of rotational velocity and dynamical properties of galaxies. Hence here we focus on searching for edge-on LSBGs. In order to find these edge-on dim galaxies, a series of effects caused by inclination, including the surface brightness profile, internal extinction, and scale length, have been corrected. In this work, we present a catalog of 281 edge-on LSBG candidates, which are selected from the crossmatch between Sloan Digital Sky Survey Data Release 7 and the 40% ALFALFA catalog. We also present the properties of these edge-on LSBG candidates including the absolute magnitude, central surface brightness, B − V color, scale length, and relative thickness. Our result suggests that the correction of inclination effects is very important for obtaining a complete sample of LSBGs.
Le coût de l’enfant et le capital humain

Une étude intitulée « Compte de l’enfance », publiée en France par un organisme statistique des ministères sociaux, vise à chiffrer ce que les dispositions fiscales et sociales procurent comme « avantages » aux personnes ayant des enfants à charge. Or cette étude ignore ce que le fait d’élever des enfants apporte à la société dans son ensemble. Une analyse économique objective nécessite d’introduire le concept de capital humain et d’investissement dans le capital humain et de prendre en compte les apports scientifiques d’Alfred Sauvy.

Lorsque l’accompagnement entrepreneurial « pro bono » devient un levier stratégique pour favoriser l’innovation. Une étude exploratoire au sein d’un cabinet de conseil
Authors: Saleh Yasmine 
Published: June 2020

Plutôt que d’engager une transformation en interne, longue par nature en raison des apprentissages organisationnels et culturels qu’elle requiert, le rapprochement avec les start-up ou avec les structures d’accompagnement entrepreneurial promet aux entreprises de mieux répondre aux exigences de leur environnement, marqué par une forte digitalisation, et d’innover rapidement. Cette recherche explore le déploiement de ces stratégies de rapprochement en se focalisant sur le cas du lancement par un cabinet de conseil d’une structure d’accompagnement entrepreneurial en tant que structure ad hoc en innovation. Selon une approche qualitative de collecte de données, la recherche donne à voir comment le programme d’accompagnement des porteurs de projet a permis de développer la créativité organisationnelle du cabinet du fait du caractère « pro bono » de l’accompagnement. La recherche met également la lumière sur les tensions sous-jacentes à cette relation d’accompagnement avant de proposer plusieurs implications managériales.
