Welcome to motherhood
Authors: Maruyama Michiko 
Published: December 2019

My doctors said it was impossible... After all the radiation and chemotherapy, I was told that I would not be able to have children. We searched for a surrogate, we looked into adoption… it seemed so hopeless and then, it happened. I was a bit nervous to tell my program because I am the first University of Alberta cardiac surgery resident to become pregnant. I did not expect their response, “Michiko, our job is to create excellent surgeons. Being an excellent surgeon does not just include being technically skilled. It involves being well rounded and excelling at all areas of life. If part of your life involves being a mother and having a family, then we are here to support and encourage you all the way.” I am proud to share that I am the mother of a beautiful baby boy.
"Welcome to Motherhood” is an illustrative photograph that represents my experience as a surgical resident and, at the time, a soon to be mother. I am the first cardiac surgery resident at the University of Alberta to become pregnant. I am so thankful to my program for all their support and encouragement throughout my pregnancy and after, when I entered motherhood. The relevance to cardiovascular science is that I feel it is important to acknowledge my cardiac surgery programs response to my pregnancy announcement. In a male dominated field with no experience of pregnant trainees, they did an incredible job to support and encourage me along the way.

THE IMPLEMENTATION OF COLLABORATIVE STRATEGY WITH INTEGRATED WRITING SKILLS IN ENGLISH LANGUAGE CLASSROOM AT MERCUBUANA UNIVERSITY
Authors: Budiarto Budiarto 
Published: December 2019

The purpose of this study is to investigate on how the teaching of integrated writing skills can be implemented through collaborative strategy. Writing skills need to be combined with other skills, because students need a lot of reading in order to obtain information, ideas and examples of correct writing. On the other hand feedback and ideas can also be gained by listening to what the teacher or a friend says. Fellow students can also discuss their writing and work together to develop ideas, discuss the use of grammar, the right words and rules in writing. Since writing skills requires a lot of rules and a long process, the collaboration is expected to reduce the burden experienced by the students. However, teachers should ensure that the collaboration is actually done by students properly by observing their activity, participation, and motivation in writing. Peer-reviewing activities can be used to monitor on how students actively engage in the writing process. Research was conducted at Mercubuana University is a qualitative research that focuses on how a lecturer teaches the students writing skills as an integrated skill, how she facilitates students to actively participate in collaborative writing, and how effectively she encourages the students to do peer reviewing.

Authors: Suprihandani Eny , Jacinda Thea 
Published: December 2019

Literature can be analyzed from many perspectives and point of views. By using psychoanalytic approach, this paper attempts to analyze one of the Shakespearean’s characters, Antony in the drama Antony and Cleopatra. The objective is to prove whether Antony truly suffers from Borderline Personality Disorder. Borderline Personality Disorder (BPD) is a personality disorder whose essential features are a pattern of marked impulsivity and instability of affects, interpersonal relationships, and self-image. Psychoanalysis theory is a theory developed by Sigmund Freud that enables to analyze whether a person suffers from a certain mental disease. Using those approaches, the characterization of Antony can be analyzed from his words, thoughts and other character’s opinion about him and then compared to the symptoms of Borderline Personality Disorder (BPD) and then found if they are matched. That Antony suffers from Borderline Personality Disorder can be finally proved.

Transition Region Loops in the Very Late Phase of Flux Emergence in IRIS Sit-and-stare Observations
Authors: Huang Zhenghua , Li Bo , Xia Lidong , Shi MiJie , Fu Hui , Hou Zhenyong 
Published: December 2019

Abstract
Loops are one of the fundamental structures that trace the geometry of the magnetic field in the solar atmosphere. Their evolution and dynamics provide a crucial proxy for studying how the magnetized structures are formed and heated in the solar atmosphere. Here, we report on spectroscopic observations of a set of transition-region loops taken by the Interface Region Imaging Spectrograph (IRIS) at Si iv 1394 Å in the sit-and-stare mode. The loops are corresponding to the flux emergence at its very late phase when the emerged magnetic features in the photosphere have fully developed. We find the transition-region loops are still expanding and moving upward with a velocity of a few kilometers per second (≲10 km s−1) at this stage. The expansion of the loops leads to interactions between the loops themselves and with the ambient field, which can drive magnetic reconnection evidenced by multiple intense brightenings, including transition-region explosive events and IRIS bombs in the footpoint region associated with the moving polarity. A set of quasi-periodic brightenings with a period of about 130 s is found at the loop apex, from which the Si iv 1394 Å profiles are significantly non-Gaussian with enhancements at both blue and red wings at Doppler velocities of about 50 km s−1. We suggest that the transition-region loops in the very late phase of flux emergence can be powered by heating events generated by the interactions between the expanding loops and the ambient fields and also by (quasi-)periodic processes, such as oscillation-modulated braiding reconnection.

Abstract
We perform a stacking analysis of Planck, AKARI, Infrared Astronomical Satellite, Wide-field Infrared Survey Explorer, and Herschel images of the largest number of (candidate) protoclusters at z ∼ 3.8 selected from the Hyper Suprime-Cam Subaru Strategic Program. Stacking the images of the 179 candidate protoclusters, the combined infrared (IR) emission of the protocluster galaxies in the observed 12–850 μm wavelength range is successfully detected with >5σ significance (at Planck). This is the first time that the average IR spectral energy distribution (SED) of a protocluster has been constrained at z ∼ 4. The observed IR SEDs of the protoclusters exhibit significant excess emission in the mid-IR compared to that expected from typical star-forming galaxies (SFGs). They are reproduced well using SED models of intense starburst galaxies with warm/hot dust heated by young stars, or by a population of active galactic nucleus (AGN)/SFG composites. For the pure star-forming model, a total IR (from 8–1000 μm) luminosity of

Meanwhile, no significant IR flux excess is observed around optically selected QSOs at similar redshifts, which confirms previous results. Our results suggest that the z ∼ 4 protoclusters trace dense, intensely star-forming environments that may also host obscured AGNs missed by the selection in the optical.
Gravitational-wave Sources from Mergers of Binary Black Holes Catalyzed by Flyby Interactions in the Field
Authors: Michaely Erez , Perets Hagai B. 
Published: December 2019

Abstract
Several scenarios were suggested for the origins of gravitational-wave (GW) sources from mergers of stellar binary black holes (BBHs). Here we propose a novel origin through catalyzed formation of GW sources from ultra-wide binaries in the field. Such binaries experience perturbations from random stellar flybys that excite their eccentricities. Once a wide binary is driven to a sufficiently small pericenter approach, GW emission becomes significant, and the binary inspirals and merges. We derive an analytic model and verify it with numerical calculation to compute the merger rate to be

(f
wide is the fraction of wide BH-binaries), which is a relevant contribution to the observationally inferred rate. The observational signatures from this channel include spin-orbit misalignment; preference for high mass ratio BBH; preference for high velocity dispersion host galaxies; and a uniform delay-time distribution.
Filling the Mass Gap: How Kilonova Observations Can Unveil the Nature of the Compact Object Merging with the Neutron Star
Authors: Barbieri C. , Salafia O. S. , Colpi M. , Ghirlanda G. , Perego A. , Colombo A. 
Published: December 2019

Abstract
In this Letter we focus on the peculiar case of a coalescing compact-object binary whose chirp mass is compatible both with a neutron star–neutron star and black hole–neutron star system, with the black hole in the ∼3–5 M
⊙ range defined as the “mass gap.” Some models of core-collapse supernovae predict the formation of such low-mass black holes and a recent observation seems to confirm their existence. Here we show that the nature of the companion to the neutron star can be inferred from the properties of the kilonova emission once we know the chirp mass, which is the best constrained parameter inferred from the gravitational signal in low-latency searches. In particular, we find that the kilonova in the black hole–neutron star case is far more luminous than in the neutron star–neutron star case, even when the black hole is nonspinning. The difference in the kilonovae brightness arises primarily from the mass ejected during the merger. Indeed, in the considered interval of chirp masses, the mass ejection in double neutron star mergers is at its worst as the system promptly forms a black hole. Instead mass ejection for the black hole–neutron star case is at its best as the neutron stars have low mass/large deformability. The kilonovae from black hole–neutron star systems can differ by two to three magnitudes. The outcome is only marginally dependent on the equation of state. The difference is above the systematics in the modeling.
Candidate Hypervelocity Red Clump Stars in the Galactic Bulge Found Using the VVV and Gaia Surveys*
Authors: Luna Alonso , Minniti Dante , Alonso-García Javier 
Published: December 2019

Abstract
We propose a new way to search for hypervelocity stars (HVS) in the Galactic bulge, by using red clump (RC) giants, that are good distance indicators. The second Gaia Data Release and the near-IR data from the VISTA Variables in the Via Lactea (VVV) Survey led to the selection of a volume limited sample of 34 bulge RC stars. A search in this combined data set leads to the discovery of seven candidate hypervelocity red clump stars in the Milky Way bulge. Based on this search we estimate the total production rate of hypervelocity RC stars from the central supermassive black hole (SMBH) to be N
HVRC = 3.26 × 10−4 yr−1. This opens up the possibility of finding larger samples of HVS in the Galactic bulge using future surveys, closer to their main production site, if they originated from interactions of binaries with the central SMBH.
LBT/PEPSI Spectropolarimetry of a Magnetic Morphology Shift in Old Solar-type Stars*
Authors: Metcalfe T. S. , Kochukhov O. , Ilyin I. V. , Strassmeier K. G. , Godoy-Rivera D. , Pinsonneault M. H. 
Published: December 2019

Abstract
Solar-type stars are born with relatively rapid rotation and strong magnetic fields. Through a process known as magnetic braking, the rotation slows over time as stellar winds gradually remove angular momentum from the system. The rate of angular momentum loss depends sensitively on the magnetic morphology, with the dipole field exerting the largest torque on the star. Recent observations suggest that the efficiency of magnetic braking may decrease dramatically in stars near the middle of their main-sequence lifetimes. One hypothesis to explain this reduction in efficiency is a shift in magnetic morphology from predominantly larger to smaller spatial scales. We aim to test this hypothesis with spectropolarimetric measurements of two stars that sample chromospheric activity levels on opposite sides of the proposed magnetic transition. As predicted, the more active star (HD 100180) exhibits a significant circular polarization signature due to a nonaxisymmetric large-scale magnetic field, while the less active star (HD 143761) shows no significant signal. We identify analogs of the two stars among a sample of well-characterized Kepler targets, and we predict that the asteroseismic age of HD 143761 from future Transiting Exoplanet Survey Satellite observations will substantially exceed the age expected from gyrochronology. We conclude that a shift in magnetic morphology likely contributes to the loss of magnetic braking in middle-aged stars, which appears to coincide with the shutdown of their global dynamos.
