The Gay and Lesbian Movement in Belgium from the 1950s to the Present
Authors: Borghs Paul 
Published: February 2017

Abstract
The small country of Belgium has become one of the world’s frontrunners in the extension of legal rights to gay and lesbian people. Belgium was, for example, the second country in the world (after the Netherlands) to legalize marriage for same-sex couples. The Belgian gay and lesbian movement played an important role in the emancipation and acceptance of—and the extension of rights to—the gay and lesbian population. This contribution outlines the history of the Belgian gay and lesbian movement from its beginning in the 1950s to the present day.1 The Belgian gay and lesbian movement had a difficult start, followed by periods of success alternating with periods of tension and conflict. The gay and lesbian movement eventually became one of the most successful social movements in Belgium.

We describe the case of a teenage girl with anthracycline-induced cardiomyopathy who received a HeartWare ventricular assist device and underwent successful device explantation after cardiac recovery.
During device support, the patient's cardiac function returned to normal. Twelve months after implantation, we explanted the device via repeat median sternotomy. To close the hole in the left ventricular apex and preserve the sewing ring in case future device support is needed, we used a German-manufactured titanium plug, developed specifically for this purpose. To our knowledge, this is the first use of this plug in the United States.
The patient recovered uneventfully and was discharged from the hospital on postoperative day 11. Left ventricular biopsy specimens at explantation revealed the resolution of previous degenerative sarcomeric changes.
Our patient did well clinically; however, recurrent late anthracycline cardiotoxicity might subsequently cause her cardiac function to deteriorate. In this event, our use of the titanium plug to preserve the left ventricular sewing ring would enable easier device replacement than would other explantation options.
The influence of vibrations on surface roughness formed during precision boring
Authors: Korzeniewski Dariusz , Znojkiewicz Natalia 
Published: February 2017

Abstract
In this paper, the analysis of vibrations on surface roughness generated during boring with the application of the conventional boring tool and one with the damper is presented. The experiments included the measurement of vibration accelerations carried out with the piezoelectric sensor, as well as the evaluation of surface roughness parameters after each machining pass. The obtained results reveal that in the investigated range, no stability loss was found. Furthermore, the growth of the rotational speed induces the increase of vibration level, as well as the growth of the differences between the vibration values generated during boring with the conventional tool and one equipped with damper. Vibrations have also the direct influence on the machined surface roughness. In case of the tool equipped with the damper, the tool’s overhang L had more intense influence than rotational speed n. However, for the conventional boring tool this dependency was unequivocal.

Published: February 2017

Abstract
A fully steerable parabolic antenna RT-32 with the mirror diameter 32 m owned by the Ventspils International Radio Astronomy Centre (VIRAC) is available for fundamental and applied research in radio astronomy. The RT-32 is supplied with the receiving systems for the frequency range 327 MHz to 12 GHz. The equipment allows recording of signals in two channels with a bandwidth up to 1 GHz in each. The system has a high stability of the time frame, which is prerequisite for the Very Long Baseline Interferometry (VLBI) observations. In 2012 the RT-32 data receiving systems and the network infrastructure were prepared for the work in the e-VLBI mode. The systems were tested together with the Torun observatory, and later in the EVN e-VLBI observation session at 5 GHz. Experiments have shown that RT-32 is able to observe at a frequency range of 5 GHz and transfer the data in the e-VLBI mode with the speed up to 1 Gbps. The paper describes the current status of RT-32, the application of its receiving and data acquisition units for the e-VLBI observations and the results of the conducted e-VLBI observational experiments.

Abstract
An international VLBI experiment on radio location of the asteroid 2012 DA14 was organized on 2013 February 15–16, during its flyby close to Earth. The purpose of observations was to investigate and specify orbital parameters of the asteroid, as well as to evaluate its rotation period and other characteristics. The irradiation of the asteroid was performed by the RT-70 transmitter at Evpatoria (Crimea, Ukraine), while the reflected signals were successfully accepted by the two 32 m radio telescopes at Medicina (Bologna, Italy) and Irbene (Ventspils, Latvia). Processing and interpretation of the data were performed both in the Radiophysical Research Institute at Nizhny Novgorod and in the Ventspils International Radio Astronomy Center. The first results of this experiment are presented and discussed.

Published: February 2017

AbstractPhotometric observations of GQ Mus performed between 1992 and 2011 are reported. We find that the total amplitude of the orbital modulation of its brightness decreased from ~ 0.9 mag in 1992 to ~ 0.2 mag in 2010, becoming comparable to the amplitude of chaotic flickering on a time scale of several minutes. Optical spectra obtained in 2001 and 2012 indicate continuing activity of GQ Mus. The spectra show broad emission lines of He II and H I typical for magnetic cataclysmic variables. The nova was found to be an UV-bright object in 2001 and 2012. We also show that the orbital period of GQ Mus has been constant between 1989 and 2010–2011.

Authors: Taş Günay , Evren Serdar 
Published: February 2017

AbstractFour-color photometry of IO Com, a detached eclipsing binary with a long period (~53 d), was accomplished in 2004–2008. The absolute astrophysical and orbital parameters of the system were determined by the analysis of the light and radial velocity curves. No secondary minima in the light curves were detected. It was revealed that IO Com is the system with a highly eccentric orbit consisting of the components of mid-F spectral types. The calculated masses and radii of the primary and secondary components are: 1.32
On the Mass Distribution of Stellar-Mass Black Holes
Authors: Malkov O. Yu. 
Published: February 2017

Abstract
The observational stellar-mass black hole mass distribution exhibits a maximum at about 8 M
⊙. It can be explained via the details of the massive star evolution, supernova explosions, or consequent black hole evolution. We propose another explanation, connected with an underestimated influence of the relation between the initial stellar mass and the compact remnant mass. We show that an unimodal observational mass distribution of black holes can be produced by a power-law initial mass function and a monotonic “remnant mass versus initial mass” relation.
On the Construction of a New 3D Atlas of Stellar Spectral Energy Distributions
Authors: Mironov A. V. , Zakharov A. I. , Moshkalev V. G. , Malkov O. Yu. , Kilpio E. Yu. 
Published: February 2017

Abstract
Modern spectrophotometric atlases are burdened with significant systematic errors. In particular, the problems of spectrum calibration in the ultraviolet region are not solved; different parts of the spectrum are not thoroughly fit to each other; spectra of (even bright) stars, obtained by different authors, display large discrepancies. Here we discuss a possibility to construct a new atlas of spectral energy distributions (SEDs) for a large set of stars by comparison of empirical stellar spectra in dozens of modern spectrophotometric atlases, as well as the comparison of synthetic and observed color indices in different multicolor photometric systems. In this way we suppose to exclude most of systematic errors and construct a new three-dimensional (spectral class, luminosity class, metallicity) atlas of empirical stellar spectra for several thousand stars. After exclusion of interstellar reddenings, a semi-empirical atlas of average SEDs can be constructed for about 150–200 spectral subtypes. This would allow us to make calibrations of spectrophotometric and photometric parameters in terms of spectral types and physical parameters (T
eff, log g, [m/H]) and to verify the accuracy of model stellar atmospheres.
Properties of Open Clusters in the Regions of the Local Bubble and the Eridanus Superbubble
Authors: Gozha M. L. , Marsakov V. A. 
Published: February 2017

Abstract
Features of the relative positions of open clusters and two superbubbles in the vicinity of the Sun, the Local Bubble and the Eridanus Superbubble, are considered. It is shown that the open clusters are concentrated toward the neutral gas shell of the Local Bubble, while there is a deficiency of clusters inside the cavity. All clusters associated with the Eridanus Superbubble belong to a compact group at the northern edge of the shell; no clusters are present inside the superbubble. Kinematics, age, and other physical and chemical properties of the clusters are investigated. It is found that the metal-deficient clusters and the clusters with high velocities are absent in the sample considered; i.e. the properties of the clusters associated with the Local Bubble and the Eridanus Superbubble are typical of the thin disk objects of the Galaxy.

million km (86.4% of the Earth orbit diameter). Each of the two Tsukanova–Korsch three-mirror astrographs has an aperture of 1m and focal length of 30 m; the focal-plane CCD array is 350 mm in diameter. The expected astrometric accuracy is ±0.0007″ in a single measurement. Each frame in the scientific program is captured synchronously by the two astrographs, allowing to obtain instantaneous parallaxes of stars as far as up to 5 kpc, along with spectral energy distributions (SEDs) of point and extended sources in the Tholen filter system (Zellner et al. 1985) extended to 12–14 bands, including the integral one. We expect the project to provide a large amount of important information for stellar astronomy and for various studies of Galactic objects.

Published: February 2017

Abstract
We describe the first light of a new 9-channel wide-field optical monitoring system with sub-second temporal resolution, Mini-MegaTORTORA, which is being tested now at the Special Astrophysical Observatory in Russian Caucasus. The system is able to observe the sky simultaneously in either wide (~900 deg2) or narrow (~100 deg2) fields of view, either in clear light or with any combination of color (Johnson B, V or R) and polarimetric filters installed, with exposure times ranging from 100 ms to 100 s. The primary goal of the system is the detection of rapid (with sub-second characteristic time scales) optical transients, but it may be also used for studying variability of sky objects over longer time scales.
Visual Binaries: Cross-Matching and Compiling of a Comprehensive List
Authors: Isaeva A. A. , Kovaleva D. A. , Malkov O. Yu. 
Published: February 2017

Abstract
Visual binary stars make up the largest set among observed types of binaries (currently more than 110 000 systems are known containing more than 230 000 components). However, statistical analysis of this sample is a complicated task because a number of catalogues of visual binaries contain various data for evidently overlapping sets of objects. To use the complete dataset, one needs to cross-match these catalogues, i.e. to gather all the available information on visual binary stars into a single list. We have compiled a comprehensive set of visual binaries using data from the current versions of the Catalog of Components of Double & Multiple stars (CCDM); Tycho Double Star Catalogue (TDSC), and The Washington Visual Double Star Catalog (WDS). The resulting list1 contains 130 873 pairs, and we also provide trigonometric parallaxes for 14 319 of them drawn mostly from the Hipparcos catalogue.
Observational Data and Orbits of the Asteroids Discovered at the Baldone Observatory in 2008–2013
Authors: Černis K. , Wlodarczyk I. , Eglitis I. 
Published: February 2017

Abstract
The paper presents statistics of the asteroids observed and discovered at the Baldone Observatory, Latvia, in 2008–2013 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets. CCD observations of the asteroids were obtained with the 0.80/1.20 m, f/3 Schmidt telescope and a ST-10XME 15 × 10 mm CCD camera. In the Minor Planet Circulars and the Minor Planet Electronic Circulars (2008–2013) we published 3511 astrometric positions of 826 asteroids. Among them, 43 asteroids were newly discovered at Baldone. For 36 of these asteroids the precise orbits are calculated. Because of short observational arc and small number of observations, a few asteroids have low-precision orbits and their tracks have been lost. For seven objects with poorly known orbits we present their ephemerides for 2015–2016. The orbits and the evolution of orbital elements of two asteroids, (428694) 2008 OS9 from the Apollo group and the Centaur (330836) Orius (2009 HW77), are recalculated including new observations obtained after 2011.
Structural Parameters of Star Clusters: Signal to Noise Effects
Authors: Narbutis D. , Bridžius A. , Semionov D. 
Published: February 2017

Abstract
We study the impact of photometric signal to noise on the accuracy of derived structural parameters of unresolved star clusters using MCMC model fitting techniques. Star cluster images were simulated as a smooth surface brightness distribution following a King profile convolved with a point spread function. The simulation grid was constructed by varying the levels of sky background and adjusting the cluster’s flux to a specified signal to noise. Poisson noise was introduced to a set of cluster images with the same input parameters at each node of the grid. Model fitting was performed using “emcee” algorithm. The presented posterior distributions of the parameters illustrate their uncertainty and degeneracies as a function of signal to noise. By defining the photometric aperture containing 80% of the cluster’s flux, we find that in all realistic sky background level conditions a signal to noise ratio of ~50 is necessary to constrain the cluster’s half-light radius to an accuracy better than ~20%. The presented technique can be applied to synthetic images simulating various observations of extragalactic star clusters.

Published: February 2017

AbstractThe Binary star Database (BDB) is the world’s principal database of binary and multiple systems of all observational types. In particular, it should contain data on binaries discovered in non-optical bands, X-ray binaries (XRBs) and radio pulsars in binaries. The goal of the present study was to compile complete lists of such objects.Due to the lack of a unified identification system for XRBs, we had to select them from five principal catalogues of X-ray sources. After cross-identification and positional cross-matching, a general catalogue of 373 XRBs was constructed for the first time. It contains coordinates, indication of photometric and spectroscopic binarity, and extensive cross-identification. In the preparation of the catalogue, a number of XRB classification disagreements were resolved, some catalogued identifiers and coordinates were corrected, and duplicated entries in the original catalogues were found.We have also compiled a general list of 239 radio pulsars in binary systems. The list is supplied with indication of photometric, spectroscopic or X-ray binarity, and with cross-identification data.

Published: February 2017

AbstractThe internal potential of an inhomogeneous layered spheroid with a small ellipticity and general exponential density distribution is derived in an analytical form. The results are presented in the form of standard Gauss hypergeometric function and validated numerically. The computing time when using this formula is noticeably smaller than the time required by numerical integration.

Published: February 2017

Abstract
The research focus is the territorial planning documents of different level valid in the territory of Lithuania, and the phenomenon of rural-urban interface reflected in them. The methods applied include the desktop study aimed at determining the presence of rural-urban influence, the character of rurban landscapes, their potential, current state of their management and development possibilities as reflected in the existing planning documents. The conclusions demonstrated not only the presence and the fragmented character of rurban areas in Lithuania, but also their potential as representative and widely accessible accumulation of cultural heritage and exceptional landscape feature of the country.
Subjects and Objects of the Embodied Gaze: Abbas Kiarostami and the Real of the Individual Perspective
Authors: Gyenge Zsolt 
Published: February 2017

AbstractIt is widely accepted that Abbas Kiarostami’s cinema revolves around the representation of the gaze. Many critics argue that he should be considered a late modernist who repeats the self-reflexive gestures of modernist European cinema decades after they were first introduced. The present paper will contradict this assertion by investigating the problematic of the Kiarostamian gaze and analyzing the perceptual side of the act of looking. I will argue that instead of focusing on the gaze of the spectator directed towards the filmic image, he exposes a gaze that is fully integrated into the reality to be captured on film. The second part of the paper will explain this by linking the concept of gaze to the Lacanian concept of the order of the Real. Finally, I will contextualize all this by discussing the Iranian director’s position between Eastern and Western traditions of representation.
Finite-dimensional H∞ control of a parallel-flow heat exchange process
Authors: Sano H. 
Published: February 2017

Abstract
This paper is concerned with the H∞ control problem of a coupled transport-diffusion system with Neumann boundary condition, related to parallel-flow heat exchange process. It is shown that, by using the previous approach for a single diffusion system, the H∞ control problem can be solved by constructing a residual mode filter (RMF)-based controller which is of finite-dimension. A numerical simulation result is given to demonstrate the validity of the proposed method.

Abstract
Annealed iron-platinum (FePt) is ferromagnetic in a nanoscale regime which is necessary for energy and data storage, whereas the as-synthesized form of FePt-based nanoparticles exhibits superparamagnetism useful for biomedical applications. In this study, as-synthesized nanosuspensions from the reaction of Pt(acac)2 with Fe(acac)3 and Fe(hfac)3 are compared. X-ray diffraction (XRD) peaks for both samples are assigned to the FePt3 phase. As shown by transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS), nanoparticles synthesized by using Fe(acac)3 have a smaller average diameter, but larger polydispersity index and particle agglomerations. On the other hand, the nanoparticles synthesized by using Fe(hfac)3 can self-assemble into a longer range of patterned monolayer. Dynamic light scattering (DLS), measuring the size of cluster of nanoparticles as well as oleic acid and oleylamine at their surface, confirms that larger agglomerations in the sample were synthesized by using Fe(acac)3. In addition to the size distribution, magnetic properties were influenced by the composition of these nanoparticles.
