The Study of Rudraksha Bead showing a Symbol of OM
Authors: RAI DURG V. , JAWLA SUNIL , BAJPAI SAURABH 
Published: February 2020

A considerable interest has been generated since ages for knowledge about the bead with the universe symbol- Om. The word Om is known and considered as the beginning, middle and the end of present, past and the future. The chanting of Om brings awareness about the physical reality of the world and the human body, the subtle impressions of the mind, emotions, thoughts and beliefs of our life. According to the Indian philosophy, Om is a spiritual symbol referred to as Atman (soul) and Brahman (reality, entirety of the universe, truth, divine, supreme spirit, cosmic principles & knowledge). This syllable is one of the most important symbols in universal religion, and often found in Vedas, Upanishads & other ancient texts. It is the sacred spiritual chanting made during the recitation of spiritual texts, puja and prayers, ceremonies, weddings, meditations & Yoga. In the present work, morphological studies have been carried out to see the surface of rudraksha (Elaeocarpus ganitrus) which indicates the presence of the universal symbol as a common sight in the divine beads of rudraksha. During microscopical studies it was observed that the Om symbol was present on the surface of various cells of rudraksha bead indicating the existence of Om at cellular level. The present study further strengthens the belief that the presence of symbol Om in Universal.

Sociología urbana: evolución y renacimiento
Authors: Lamy Brigitte 
Published: February 2020

En este texto tratamos de definir la sociología urbana, sus orígenes, su mirada hacia la ciudad como objeto de estudio y cómo la define, cómo la estudia, a partir de qué temas. Se trata de ver la importancia de esta disciplina para estudiar la ciudad. La sociología urbana o de lo urbano ofrece una mirada complementaria a otras disciplinas que también se interesan por el fenómeno urbano; va mucho más allá del aspecto físico-espacial, pues la definición de ciudad para los sociólogos urbanos se encuentra precisamente en la intersección entre lo social y lo espacial. Con el apoyo de contribuciones de especialistas del área, se presenta lo que podría ser una agenda de trabajo, sus temas privilegiados de investigación y su forma de acercarse para estudiarla. El campo es inmenso y complejo, ya que consta de una gran variedad de puntos de vista a través de épocas, continentes y dentro de la misma disciplina.

Published: February 2020

The aim of this research was to verify, from analysis of the Life Conditions Index, if perceptions about life conditions between rural producers’ households (family farm or non-family farm) and rural non-farmer households differed statistically. Therefore, were executed means comparison tests (test-T) whose null hypothesis referred to equivalent means, that is, equal perceptions, and the non-null hypothesis, the opposite. The results showed difference in perceptions of life conditions between rural farm households and rural non-farm households, in other words, the non-null hypothesis was accepted. However, between family farmers’ households and non-family farmers’ households the null hypothesis was accepted.

Pariwisata merupakan salah satu generator ekonomi di Indonesia. Dalam konteks keruangan arsitektur, berkembangnya pariwisata berbanding lurus dengan pertumbuhan kawasan dan kota di suatu tempat. Fasilitas untuk mendukung pariwisata menjadi sebuah kebutuhan primer dari perencanaan pariwisata. Salah satu dampak dari kebutuhan fasilitas pariwisata adalah munculnya ruang-ruang baru di kawasan-kawasan lama yang sudah terbentuk sebelumnya. Dampak tersebut dapat memunculkan konflik keruangan. Untuk meredam konflik keruangan, maka perlu adanya tindakan adaptif berupa toleransi keruangan di lapangan. Jl. Margo Utomo, Yogyakarta merupakan salah satu penggalan jalan yang strategis dan saat ini berkembang sebagai sentra perniagaan dan pariwisata Yogyakarta. Kawasan ini memiliki akulturasi budaya dari sisi arsitektural yang menjadi ciri khas dan memiliki daya tarik tersendiri bagi masyarakat. Banyak investor yang tertarik untuk investasi di Yogyakarta dan membangun fasilitas pariwisata di jl.Margo Utomo. Pembangunan fasilitas-fasilitas baru di kawasan ini harus dicermati agar tidak terjadi konflik keruangan.Â Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Hasil penelitian ini bertujuan untuk menghasilkan kebijakan dalam keruangan arsitektur dan membangun kesadaran serta toleransi akan nilai ruang di perkotaan yang ramah terhadap pariwisata.
Pengaruh perubahan fungsi bangunan pada bentuk bangunan Bangsal Banjar Andhap Dalem Mangkubumen Yogyakarta

Published: February 2020

Dalem Mangkubumen awalnya adalah rumah tinggal bagi Putra Mahkota Kraton Yogyakarta calon Sultan Hamengkubuwono VII. Sejak dibangun mulai tahun 1874, Dalem Mangkubumen mengalami perubahan fungsi: awalnya sebagai rumah Pangeran beserta kerabat Kraton, sebagai kampus Universitas Gadjah Mada (1949-1982) dan kampus Universitas Widya Mataram sejak tahun 1982 hingga saat ini. Hal ini mengakibatkan bangunan di Dalem Mangkubumen mengalami perubahan baik tata ruangnya maupun penampilannya termasuk bangunan Bangsal Banjar Andhap.Â Â Â Â Â Â Â Â Â Â Penelitian ini dilakukan untuk mengidentifikasi perubahan tata ruang dan penampilan bangunan Bangsal Banjar Andhap akibat perubahan fungsi yang terjadi hingga saat ini. Penelitian ini diharapkan juga dapat mengungkap bagaimana tata ruang dan penampilan bangunan sebelum mengalami perubahan sehingga dapat menjadi acuan melestarikan bangunan yang asli. Agar tujuan penelitian tersebut dapat tercapai, maka cara atau metode yang dinilai tepat digunakan adalah metode grounded yang didasarkan atas penelusuran empirik.Â Â Â Â Â Â Â Â Â Â Hasil penelitian menunjukkan bahwa telah terjadi perubahan tata ruang dan penampilan bangunan Bangsal banjar Andhap sejak digunakan sebagai tempat pendidikan Fakultas Hukum Universitas Widya Mataram : yang semula terbuka tanpa dinding karena berfungsi untuk umum, menjadi tertutup berdinding luar dan partisi yang membatasi ruang-ruang Fakultas Hukum UWM. Penambahan material komponen bangunan bersifat semi permanen, sehingga tidak kesulitah apabila suatu saat harus dikembalikan ke bentuk aslinya.

Survey of Very Broad Diffuse Interstellar Bands
Authors: Galazutdinov G. , Bondar A. , Lee Byeong-Cheol , Hakalla R. , Szajna W. , Krełowski J. 
Published: February 2020

Abstract
This paper considers a very special set of a few interstellar features—broad diffuse interstellar bands (DIBs) at 4430, 4882, 5450, 5779, and 6175 ÅÅ. The set is small, and measurements of equivalent widths of these DIBs are challenging because of severe stellar, interstellar, and sometimes, also telluric contaminations inside their broad profiles. Nevertheless, we demonstrate that they do correlate pretty tightly (DIBs 4882 and 5450 to a lesser extent though) with other narrower diffuse bands, as well as with the color excess E(B−V). The studied broad DIBs correlate well with both interstellar molecule CH and interstellar K i, i.e., it is hardly possible to verify whether the environments, facilitating the formation of very broad DIB carriers, are dominated by either molecular or atomic gas as both these species likely occupy the same volume.

Abstract
The abundance of short-period planetary systems with high orbital obliquities relative to the spin of their host stars is often taken as evidence that scattering processes play important roles in the formation and evolution of these systems. More recent studies have suggested that wide binary companions can tilt protoplanetary disks, inducing a high stellar obliquity that form through smooth processes like disk migration. DS Tuc Ab, a transiting planet with an 8.138 day period in the 40 Myr Tucana–Horologium association, likely orbits in the same plane as its now-dissipated protoplanetary disk, enabling us to test these theories of disk physics. Here, we report on Rossiter–McLaughlin observations of one transit of DS Tuc Ab with the Planet Finder Spectrograph on the Magellan Clay Telescope at Las Campanas Observatory. We confirm the previously detected planet by modeling the planet transit and stellar activity signals simultaneously. We test multiple models to describe the stellar activity-induced radial velocity variations over the night of the transit, finding the obliquity to be low: λ = 12° ± 13°, which suggests that this planet likely formed through smooth disk processes and its protoplanetary disk was not significantly torqued by DS Tuc B. The specific stellar activity model chosen affects the results at the ≈5° level. This is the youngest planet to be observed using this technique; we provide a discussion on best practices to accurately measure the observed signal of similar young planets.
Exploratory Spectroscopy of Magnetic Cataclysmic Variables Candidates and Other Variable Objects. II
Authors: Oliveira A. S. , Rodrigues C. V. , Martins M. , Palhares M. S. , Silva K. M. G. , Lima I. J. , Jablonski F. J. 
Published: February 2020

Abstract
This is the second paper of a series presenting our search for magnetic cataclysmic variables (mCVs) among candidates selected mostly from the Catalina Real-Time Transient Survey. We present the identification spectra, obtained at the SOAR Telescope, as well as magnitudes and Gaia distances for 45 objects. Of these, 39 objects are identified as CVs, from which 8 targets show observational characteristics of mCVs, being 7 polars and 1 intermediate polar. The remaining 31 CVs in our sample are probably non-magnetic systems, in low (22 systems) or high (9 systems) accretion states. Six targets of the sample are not CVs (5 active galactic nuclei and 1 T Tauri star). Among the 8 objects with mCV spectra, 6 are new classifications. Three polars were observed in low-accretion state, either revealing photospheric features of the secondary star and allowing the estimation of their spectral type, or presenting Hβ Zeeman components associated to the white dwarf (WD) magnetic field. In addition to the results obtained in the first paper of the series, and depending on the confirmation of these classifications by observational follow-up, our results would increase the sample of known polars by about 9%.
Massive Stars in the SDSS-IV/APOGEE2 Survey. III. New OB Stars in the Direction of the Sagittarius Spiral Arm
Authors: Roman-Lopes Alexandre , Román-Zúñiga Carlos G. , Tapia Mauricio , Minniti Dante , Borissova Jura 
Published: February 2020

Abstract
We have applied the semi-empirical spectral analysis, developed by the Sloan Digital Sky Survey (SDSS)-IV/Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE2) Massive Star Team, to a large sample of new O- and B-type stars identified along the Sagittarius spiral arm, in the direction of the southern star clusters NGC3603 and NGC3576. We obtained H-band spectra for 265 point sources, using the APOGEE2-S spectrograph at the du Pont Telescope at the Las Campanas Observatory. We analyzed the associated spectral features deriving spectral types, as well as the massive star distribution along the line of sight. From a total of 265 science targets, 95 are classified as mid- to late-O-type stars (for which only 10 O-type stars are previously known in the literature), 38 are found to be early- to mid-B-type stars, and 32 are classified as either yellow or blue supergiants, completing a total of 165 massive stars.
An ALMA CO(2–1) Survey of Nearby Palomar–Green Quasars
Authors: Shangguan Jinyi , Ho Luis C. , Bauer Franz E. , Wang Ran , Treister Ezequiel 
Published: February 2020

Abstract
The properties of the molecular gas can shed light on the physical conditions of quasar host galaxies and the effect of feedback from accreting supermassive black holes. We present a new CO(2–1) survey of 23

Palomar–Green quasars conducted with the Atacama Large Millimeter/submillimeter Array. CO emission was successfully detected in 91% (21/23) of the objects, from which we derive CO luminosities, molecular gas masses, and velocity line widths. Together with CO(1–0) measurements in the literature for 32 quasars (detection rate 53%), there are 15 quasars with both CO(1–0) and CO(2–1) measurements and, in total, 40 sources with CO measurements. We find that the line ratio of

is subthermal and broadly consistent with nearby galaxies and other quasars previously studied. No clear correlation is found between R
21 and the intensity of the interstellar radiation field or the luminosity of the active nucleus. As with the general galaxy population, quasar host galaxies exhibit a strong, tight, and linear L
IR–

relation, with a normalization consistent with that of starburst systems. We investigate the molecular-to-total-gas mass fraction with the aid of total gas masses inferred from dust masses previously derived from infrared observations. Although the scatter is considerable, the current data do not suggest that the CO-to-H2 conversion factor of quasar host galaxies significantly differs from that of normal star-forming galaxies.
Laboratory Study of Rate Coefficients for H2:H2 Inelastic Collisions between 295 and 20 K
Authors: Montero S. , Tejeda G. , Fernández J. M. 
Published: February 2020

Abstract
A laboratory study of state-to-state rate coefficients (STS rates) for H2:H2 inelastic collisions in the v = 0 state is reported. The study, which spans the 295–20 K thermal range, is based on the use of a kinetic master equation. It describes the time-space evolution of populations of H2 rotational levels as induced by inelastic collisions. It is applied here to a supersonic jet of natural H2. This medium bears a large amount of relevant data that allows for the establishment of best values and confidence margins for the dominant STS rates of H2:H2 inelastic collisions on an experimental basis. The primary experimental data derived from the supersonic jet are the local number density, the populations of the H2 rotational levels, and their gradients along the jet by means of high-sensitivity Raman spectroscopy with superb space resolution. First, two sets of theoretical STS rates from the literature have been tested against the experiment. The set that shows a better agreement with the experiment has then been scaled to derive an improved set of experiment-scaled STS rates (ES rates). They allow the reproduction of more than 50 experimental population gradient data within a standard deviation <1.4% along the 295–20 K thermal range. The estimated uncertainty for the ES rates ranges from ≈3% near 300 K to ≈6% near 20 K. ES rates and uncertainties for H2:H2 ground-state inelastic collisions between 300 and 20 K are presented in machine-readable format. Other (incomplete) sets of theoretical rates from the literature are discussed.
Spectral Lines for Transition to Highly Excited States of Lithium in Magnetic Fields of White Dwarf Stars
Authors: Zhao L. B. 
Published: February 2020

Abstract
We develop a two-dimensional B-spline approach in the cylindrical coordinate system to simulate spectra of lithium in magnetic fields of white dwarf stars. The advantage of the current approach is that it can be applied to calculate both low- and high-lying states, while the theoretical methods for describing magnetized lithium in the literature are limited to the treatment of the ground state and low-lying excited states. The magnetized atomic states are calculated with symmetries

, and

, and the lowest 10 atomic states of each symmetry are involved. The magnetic field strengths stride a scope of field strengths of white dwarf stars. Atomic data of absorption spectra corresponding to transitions from the ground state or low-lying excited states to high-lying excited states are reported for magnetized lithium. These atomic data include energy levels, wavelengths, and oscillator strengths. Comparison is made between our results, and theoretical and experimental data reported in the literature. The current two-dimensional B-spline approach can systematically produce atomic data to model discrete atomic spectra of both low- and high-lying states of lithium in magnetic white dwarf stars.
Iterative Phase Correlation Algorithm for High-precision Subpixel Image Registration
Authors: Hrazdíra Zdenek , Druckmüller Miloslav , Habbal Shadia 
Published: February 2020

Abstract
Many astrophysical observations and measurement techniques that rely on data from images include an image registration step. The results of such techniques thus heavily rely on the precision of the registration. We present an Iterative Phase Correlation (IPC) algorithm, which is an extension of the well-known phase correlation method of image registration and is ideally suited for problems, where the subpixel registration accuracy plays a crucial role. Furthermore, a sophisticated and reliable method of optimal IPC parameter estimation is described. The paper includes examples of such optimized parameters for Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager, SDO/Atmospheric Imaging Assembly, and Solar Terrestrial Relations Observatory A/B Sun Earth Connection Coronal and Heliospheric Investigation images. The new method (both with or without the parameter optimization step) significantly outperforms standard image registration methods, such as (non-iterative) phase correlation or (normalized) cross correlation in the sense of subpixel accuracy. A step-by-step pseudocode implementation is also included.
Narrowband Ca Photometry for Dwarf Spheroidal Galaxies. I. Chemostructural Study on Draco, Sextans, and Canes Venatici I*

Published: February 2020

Abstract
A few dozen dwarf satellite galaxies of the Milky Way have been discovered, which are often viewed as the remaining building blocks of our Galaxy. The follow-up spectroscopy showed that dwarf galaxies have a sizeable spread in their metallicities. Several scenarios were suggested to explain the metallicity spread, which can be tested by the structural patterns of stellar subpopulations with distinct metallicities. However, such chemical plus structural examination, which we refer to as “chemostructural study,” is hindered by the lack of stars with spectroscopic metallicity. Here we propose the Ca–by photometry as an alternative way to secure metallicities for a 2–3 orders of magnitude larger stellar sample than the spectroscopic sample and thus enable us to perform a chemostructural study on dwarf galaxies. In particular, we use the hk index [≡(Ca − b) − (b − y)], whose validity as a photometric metallicity indicator (and crass insensitivity to age) for red-giant-branch stars was upheld via Galactic globular clusters, and observe three dwarf spheroidal galaxies—Draco, Sextans, and Canes Venatici I (CVnI)—with Subaru/Suprime-Cam. We find that in all the galaxies the metal-rich stellar populations are more centrally concentrated than the metal-poor counterparts, suggesting that the central regions of the galaxies underwent extended star formation. Such a negative radial metallicity gradient for Sextans and CVnI opposes the traditional spectroscopic results. We also find that their metallicity distribution functions (MDFs) can be characterized by a unimodal, skewed Gaussian shape with a metal-rich peak and a metal-poor tail. We discuss their features in the chemo-structure and MDF in terms of dwarf galaxy formation theories.
A Magnetohydrodynamic Relaxation Method for Non-force-free Magnetic Field in Magnetohydrostatic Equilibrium
Authors: Miyoshi Takahiro , Kusano Kanya , Inoue Satoshi 
Published: February 2020

Abstract
A nonlinear force-free field (NLFFF) extrapolation is widely used to reconstruct the three-dimensional magnetic field in the solar corona from the observed photospheric magnetic field. However, the pressure gradient and gravitational forces are ignored in the NLFFF model, even though the photospheric and chromospheric magnetic fields are not in general force-free. Here we develop a magnetohydrodynamic (MHD) relaxation method that reconstructs the solar atmospheric (chromospheric and coronal) magnetic field as a non-force-free magnetic field (NFFF) in magnetohydrostatic equilibrium where the Lorentz, pressure gradient, and gravitational forces are balanced. The system of basic equations for the MHD relaxation method is derived, and mathematical properties of the system are investigated. A robust numerical solver for the system is constructed based on the modern high-order shock capturing scheme. Two-dimensional numerical experiments that include the pressure gradient and gravitational forces are also demonstrated.
