The subjects of the study are methods and devices of generating gas mixtures with a specified accuracy and a high repeatability of the component dosing. The purpose of the article is to develop an algorithm for controlling the fuel mixture generation system for precision thermal pulse treatment. In that behalf, the research tasks are the improvement of the critical hole method with reference to the thermal pulse treatment and the methodology development of parameters assigning for mixture generation system ensuring high accuracy and repeatability of the dosing of its components and heat flows in thermal pulse treatment. The following results are obtained. The method of dynamic mixture formation based on the method of critical holes is proposed. Its special advantage is that during the filling of the chamber, the components of the fuel mixture expire from the pre-filled intermediate pressure vessels with the controlled volume without the application of any regulating devices. The technique for choosing the diameters of critical apertures, the volumes of intermediate tanks and the initial pressure in them, providing accuracy of components dosing at the level 0,01 % is developed. The technical solutions that allow to stabilize the value of heat flow during thermal pulse treatment, considering the operation dynamics of the valves in the mixture generation system and the variable temperature of the chamber walls are proposed. The following conclusions are formulated. The method of generating fuel mixtures for precision thermal pulse treatment based on the method of critical holes is proposed. It is characterized by the fact that during the mixture formation, the free exhaust of gases from pre-filled intermediate tanks is applied. The developed procedure for calculating the parameters of the mixture generator on the basis of the proposed method makes it possible to determine the ratio of the areas of the critical holes, the volumes of the tanks, the initial pressure in them and the time of filling the chamber according to the given composition and pressure of the mixture at normal temperature. The algorithm for controlling the generation of a mixture for precision thermal pulse processing is developed. The necessity of controlling the opening and closing speed of the gas supply valves is shown taking into account the required ratio of the areas of critical holes. To ensure a stable value of heat fluxes during cyclic thermal pulse treatment, it is shown that it is necessary to simultaneously monitor the charge mass and the pressure in the chamber when the fuel mixture is supplied, followed by correcting the treatment time according to the calculated initial temperature of the fuel mixture

Depression is an unfavorable condition for the elderly. When depression goes untreated, elderly can isolate themselves even allowed to end his life. Spiritual Emotional Freedom Technique (SEFT) and Keroncong music allegedly can be used as complementary therapy for elderly depression. This study aimed to determine the difference effect of Spiritual Emotional Freedom Technique (SEFT) and Keroncong music on elderly depression at Jombang geriatric service unit in Pare Kediri. The method used was a quasi-experimental, with a pretest and posttest design. In this study, respondents were grouped into two groups, SEFT intervention group (n=10) and Keroncong music Intervention group (10). In both groups was given four therapy sessions, within four weeks, each session is given therapy for 30 minutes.. In this study it was found that the decrease of score depression between pretest and posttest at SEFT therapy (p = 0,008) and keroncong music therapy (p = 0,01). By unpaired t test, posttest obtained, the p value (p=0,760) >0.05 so that there is no significant difference between the posttest score in the SEFT Therapy group and the keroncong music therapy group. It can be concluded that SEFT and keroncong music reduce depression in elderly, but no more effective between SEFT and keroncong music reduce depression in elderly.

Welcome to the fourth volume of Mutual Images.

This is the output of our fifth yearly international workshop, which our research association organised and held at Nagoya University (Japan) on 22 and 23 April, 2017. This workshop was organised in collaboration with G30 Japan-in-Asia Cultural Studies Program (JACS) from Nagoya University, directed by Kristina Iwata-Weickgenannt. This collaboration led to a geographical delimitation of both the workshop and this volume that differ from previous events and publications done by Mutual Images Research Association. In the previous volumes, the articles explored mainly the “images” bridging between Japanese and European cultures. For this volume, we seek to consider the representations between Japan and Asia. However, as it will become apparent with the articles that compose this volume, Europe is omnipresent. The relationship between Japan and Asia also goes through Europe as another “Other”. The concepts of Selfness and Otherness in and between Japan, other Asian nations and Europe are the common grounds that link the articles.

Applying Deep Learning to Fast Radio Burst Classification
Authors: Connor Liam , van Leeuwen Joeri 
Published: November 2018

Abstract
Upcoming fast radio burst (FRB) surveys will search ∼103 beams on the sky with a very high duty cycle, generating large numbers of single-pulse candidates. The abundance of false positives presents an intractable problem if candidates are to be inspected by eye, making it a good application for artificial intelligence (AI). We apply deep learning to single-pulse classification and develop a hierarchical framework for ranking events by their probability of being astrophysical transients. We construct a treelike deep neural network that takes multiple or individual data products as input (e.g., dynamic spectra and multibeam information) and trains on them simultaneously. We have built training and test sets using false-positive triggers from real telescopes, simulated FRBs, and pulsar single pulses. Training the network was independently done for both the CHIME Pathfinder and Apertif. High accuracy and recall can be achieved with a labeled training set of a few thousand events. Even with high triggering rates, classification can be done very quickly on graphical processing units, which is essential for selective voltage dumps or real-time VOEvents. We investigate whether dedispersion back ends could be replaced by a real-time DNN classifier. It is shown that a single forward propagation through a moderate convolutional network could be faster than brute-force dedispersion, but the low signal-to-noise per pixel makes such a classifier suboptimal for this problem. Real-time automated classification will prove useful for bright, unexpected signals, both now and when searchable parameter spaces outgrow our ability to manually inspect data, such as for the SKA and ngVLA.
The Efficiency of Noble Gas Trapping in Astrophysical Environments

Published: November 2018

Abstract
Amorphous ice has long been invoked as a means for trapping extreme volatiles into solids, explaining the abundances of these species in comets and planetary atmospheres. Experiments have shown that this trapping is possible and has been used to estimate the abundances of each species in primitive ices after they have formed. However, these experiments have been carried out at deposition rates that exceed those expected in a molecular cloud or solar nebula by many orders of magnitude. Here, we develop a numerical model that reproduces the experimental results and apply it to those conditions expected in molecular clouds and protoplanetary disks. We find that two regimes of ice trapping exist: burial trapping, where the ratio of trapped species to water in the ice reflects that same ratio in the gas; and equilibrium trapping, where the ratio in the ice depends only on the partial pressure of the trapped species in the gas. The boundary between these two regimes is set by both the temperature and rate of ice deposition. These effects must be accounted for when determining the source of trapped volatiles during planet formation.
A Wide-field Map of Intracluster Globular Clusters in Coma

Published: November 2018

Abstract
The large-scale distribution of globular clusters in the central region of the Coma cluster of galaxies is derived through the analysis of Hubble Space Telescope/Advanced Camera for Surveys data. Data from three different HST observing programs are combined in order to obtain a full surface density map of globular clusters in the core of Coma. A total of 22,426 Globular cluster candidates were selected through a detailed morphological inspection and the analysis of their magnitude and colors in two wavebands, F475W (Sloan g) and F814W (I). The spatial distribution of globular clusters defines three main overdensities in Coma that can be associated with NGC 4889, NGC 4874, and IC 4051 but have spatial scales five to six times larger than individual galaxies. The highest surface density of globular clusters in Coma is spatially coincidental with NGC 4889. The most extended overdensity of globular clusters is associated with NGC 4874. Intracluster globular clusters also form clear bridges between Coma galaxies. Red globular clusters, which agglomerate around the center of the three main subgroups, reach higher surface densities than blue ones.
Wave Generation and Heat Flux Suppression in Astrophysical Plasma Systems
Authors: Roberg-Clark G. T. , Drake J. F. , Swisdak M. , Reynolds C. S. 
Published: November 2018

Abstract
Heat flux suppression in collisionless plasmas for a large range of plasma β is explored using two-dimensional particle-in-cell simulations with a strong, sustained thermal gradient. We find that a transition takes place between whistler-dominated (high-β) and double-layer-dominated (low-β) heat flux suppression. Whistlers saturate at small amplitude in the low beta limit and are unable to effectively suppress the heat flux. Electrostatic double layers (DLs) suppress the heat flux to a mostly constant factor of the free-streaming value once this transition happens. The DL physics is an example of ion–electron coupling and occurs on a scale of roughly the electron Debye length. The scaling of ion heating associated with the various heat flux driven instabilities is explored over the full range of β explored. The range of plasma-βs studied in this work makes it relevant to the dynamics of a large variety of astrophysical plasmas, including the intracluster medium of galaxy clusters, hot accretion flows, stellar and accretion disk coronae, and the solar wind.

Abstract
Bright high-redshift quasars (z > 6) hosting supermassive black holes (M

gal ≡ (N
gal − N
exp)/N
exp = −0.07 ± 0.56, consistent with no detected overdensity of dusty galaxies within 140 physical kpc of the quasars. However, the apparent lack of continuum overdensity does not negate the hypothesis that quasars live in overdense environments, as evidenced by strong [C ii] overdensities found on the same scales as similarly selected quasars. The small field of view of ALMA could miss a true overdensity if it exists on scales larger than 1 cMpc, if the quasar is not centered in the overdensity, or if quasar feedback plays a role close to the quasar, but it is most likely that the large line-of-sight volume probed by a continuum survey will wash out a true overdensity signal. We discuss the necessary factors in determining the bias with which dusty star-forming galaxies trace true dark matter overdensities in order to improve upon overdensity searches in the dust continuum.
Dense Molecular Filaments Feeding a Starburst: ALMA Maps of CO(3–2) in Henize 2–10
Authors: Beck Sara C. , Turner Jean L. , Consiglio S. Michelle 
Published: November 2018

Abstract
We present Atacama Large Millimeter/Submillimeter Array CO(3–2) observations at 0.″3 resolution of He 2–10, a starburst dwarf galaxy and possible high-z galaxy analog. The warm dense gas traced by CO(3–2) is found in clumpy filaments that are kinematically and spatially distinct. The filaments have no preferred orientation or direction; this may indicate that the galaxy is not evolving into a disk galaxy. Filaments appear to be feeding the active starburst; the velocity field in one filament suggests acceleration onto an embedded star cluster. The relative strengths of CO(3–2) and radio continuum vary strongly on decaparsec scales in the starburst. There is no CO(3–2) clump coincident with the nonthermal radio source that has been suggested to be an AGN, nor unusual kinematics. The kinematics of the molecular gas show significant activity that is apparently unrelated to the current starburst. The longest filament, east of the starburst, has a pronounced shear of FWHM ∼40 km s−1 across its ∼50 pc width over its entire ≈0.5 kpc length. The cause of the shear is not clear. This filament is close in projection to a “dynamically distinct” CO feature previously seen in CO(1–0). The most complex region and the most highly disturbed gas velocities are in a region 200 pc south of the starburst. The CO(3–2) emission there reveals a molecular outflow, of line width FWZI ∼ 120–140 km s−1, requiring an energy ≳1053 erg s−1. There is at present no candidate for the driving source of this outflow.
Rovibrational Chemistry of
, HD, and H2 in the Recombination Era
Authors: Walker Kyle M. , Porter R. L. , Stancil P. C. 
Published: November 2018

Abstract
A new model of the chemical evolution of primordial species in the Recombination Era, focusing on rovibrational molecular level populations and line emission, the main cooling process for low-temperature primordial gas, is presented. Since molecular excitation calculations are vital in determining particle velocity distributions, internal state distributions, abundances, and ionization balance in gaseous environments, our model of the early universe considers nonthermal level populations using new state-to-state collisional excitation rate coefficients and reaction rates. This model of Recombination Era astrochemistry highlights the level populations of

, HD, and H2 and expands upon the current chemical networks by considering deuterated, ionized, and excited species. We furthermore couple the heat equation to the chemical network to form a complete model of thermal balance and dynamical evolution of primordial gas in the early universe. A developmental version of the spectral synthesis package Cloudy was used to model the primordial gas, and a data set of

vibrational excitation rate coefficients due to H collisions are provided.
Statistical Properties of Paired Fixed Fields

Published: November 2018

Abstract
The initial conditions of cosmological simulations are commonly drawn from a Gaussian ensemble. The limited number of modes inside simulations gives rise to sample variance: statistical fluctuations that limit the accuracy of the simulation predictions. Fixed fields offer an alternative initialization strategy; they have the same power spectrum as Gaussian fields but no intrinsic amplitude scatter. Paired fixed fields consist of two fixed fields with opposite phases that cancel phase correlations. We study the statistical properties of those fields for 19 different quantities at different redshifts through a large set of 600 N-body and 530 state-of-the-art magnetohydrodynamic simulations. We find that paired fixed simulations do not introduce a bias on any of the examined quantities. We quantify the statistical improvement brought by these simulations on different power spectra—matter, halos, cold dark matter, gas, stars, galaxies, and magnetic fields—finding that they can reduce their variance by factors as large as 106. We quantify the improvement achieved by fixing and by pairing, showing that sample variance can be highly suppressed by pairing after fixing. Paired fixed simulations do not change the scatter in quantities such as the probability distribution function or the halo, void, or stellar mass functions. We argue that procedures aiming at reducing the sample variance of those quantities are unlikely to work. Our results show that paired fixed simulations do not affect either mean relations or scatter of galaxy properties and suggest that the information embedded in one-point statistics is highly complementary to that in clustering.
Blue Straggler Bimodality: A Brownian Motion Model
Authors: Pasquato Mario , Miocchi Paolo , Yoon Suk-Jin 
Published: November 2018

Abstract
The shape of the radial distribution of blue straggler stars (BSS), when normalized to a reference population of horizontal branch (HB) stars, has been found to be a powerful indicator of the dynamical evolution reached by a globular cluster (GC). In particular, observations suggest that the BSS distribution bimodality is modulated by the dynamical age of the host GC; dynamically unrelaxed GCs show a flat BSS distribution, and more relaxed GCs show a minimum at a radius that increases for increasing dynamical age, resulting in a natural “dynamical clock.” While direct N-body simulations are able to reproduce the general trend, thus supporting its dynamical origin, the migration of the minimum of the distribution appears to be noisy and not well defined. Here we show that a simple unidimensional model based on dynamical friction (drift) and Brownian motion (diffusion) correctly reproduces the qualitative motion of the minimum, without adjustable parameters except for the BSS to HB stars mass ratio. Differential dynamical friction effects combine with diffusion to create a bimodality in the BSS distribution and to determine its evolution, driving the migration of the minimum to larger radii over time. The diffusion coefficient is strongly constrained by the need to reproduce the migratory behavior of the minimum, and the radial dependence of diffusion set by fundamental physical arguments automatically satisfies this constraint. Therefore, our model appears to capture the fluctuation–dissipation dynamics that underpins the dynamical clock.
Optimized Radio Follow-up of Binary Neutron-star Mergers
Authors: Carbone Dario , Corsi Alessandra

Abstract
Motivated by the recent discovery of the binary neutron-star (BNS) merger GW170817, we determine the optimal observational setup for detecting and characterizing radio counterparts of nearby (d

L
∼ 40 Mpc) BNS mergers. We simulate GW170817-like radio transients, and radio afterglows generated by fast jets with isotropic energy

erg, expanding in a low-density interstellar medium (ISM;

cm−3), observed from different viewing angles (from slightly off-axis to largely off-axis). We then determine the optimal timing of GHz radio observations following the precise localization of the BNS radio counterpart candidate, assuming a sensitivity comparable to that of the Karl G. Jansky Very Large Array. The optimization is done so as to ensure that properties such as viewing angle and circumstellar density can be correctly reconstructed with the minimum number of observations. We show that radio is the optimal band to explore the fastest ejecta from BNSs in the low-density ISM, since the optical emission is likely to be dominated by the so-called “kilonova” component, while X-rays from the jet are detectable only for a small subset of the BNS models considered here. Finally, we discuss how future radio arrays like the next-generation VLA would improve the detectability of BNS mergers with physical parameters similar to those explored here.

Abstract
Precision laboratory measurements are presented for 135 O i lines in the infrared (including 51 lines not measured previously in the laboratory) using time-resolved Fourier transform infrared spectroscopy in the 800–13,000 cm−1 region. The fine structure of some lines is observed for the first time. Using our linelist together with all relevant measurements from other works, we perform a re-optimization of O i level energies to obtain an internally consistent system of 2p
3[4
S]nl levels. Some O i level energies measured long ago are corrected. We also present a long list of oscillator strengths calculated with the help of quantum defect theory.
