Published: June 2020

Aim. The potential distribution of the cardioelectric field on the body surface during the initial atrial activity and the sequence of depolarization of the atrial subepicardium in rats with experimentally induced pulmonary hypertension were compared. This work is devoted to non-invasive detection of arrhythmogenic foci of atria by using the cardioelectric field on the body surface during experimental pulmonary hypertension.Materials and methods. The method of cardioelectrochronotopography has been used to study the electric field of the heart on the body surface and the sequence of propagation of the excitation wave along the atrial epicardium in rats with experimentally induced pulmonary hypertension caused by a single injection of monocrotaline (60 mg / kg, four weeks after drug administration).Results. Pulmonary hypertension causes the appearance of an additional focus of initial excitation in the area of the pulmonary vein lacunae, which leads to an increase in the heterogeneity of the propagation of the excitation wave along the atrial epicardium. The appearance of the additional excitation focus in the mouths of the pulmonary veins in the left atrium changes the picture of the sequence of depolarization of the atrial epicardium. The heterogeneity of the propagation of the excitation wave along the atrial epicardium is reflected in a different arrangement of zones of positive and negative cardioelectric potentials on the body surface before and during the P-wave in comparison with the initial state.Conclusion. Induced pulmonary hypertension contributes to the appearance of an additional focus of initial excitation in the area of the sleeves of the pulmonary veins of the left atrium in rats. This leads to an increase in the heterogeneity of the propagation of the excitation wave along the atrial epicardium. This is also reflected in the change in the arrangement of the zones of positive and negative cardioelectric potentials on the body surface before and during the P-wave in comparison with the initial state.

Authors: Wajeetongratana Prateep 
Published: June 2020

Today’s system of accounting does not contain sufficient volumes of information about environmental incomes and losses of organizations, therefore, it is nearly impossible to evaluate precisely the efficiency of environmental actions taken and environmental protection systems being implemented in order to maintain and/or increase the environmental balance. One of the key elements in the mechanism increasing the quality of economic performance is the system of environmental accounting.
This study explains both theory and methodology of environmental accounting and also determines its role and place within the system of existing types of accounting and reporting in accordance with the IFRS requirements and also Kyoto Protocol. The presented here organizational economic mechanism of environmental accounting allows implementing the latter at concrete enterprises so that to promote and support more efficient managerial decision-making.

Reimagining the Curriculum in Study Abroad: Globalizing Multiculturalism to Prepare Future Teachers
Authors: Phillion JoAnn , Malewski Erik L. , Sharma Suniti , Wang Yuxiang 
Published: June 2020

This article discusses research that indicates that the lived experience of studying abroad provides preservice teachers the intellectual and critical starting point for multicultural awareness of the educational, social, and political relationships between their lives and other cultures. With course work and field experiences that are grounded in multicultural life-experience, the authors argue that preservice teachers begin to develop the awareness, sensitivity, and skills they urgently need to bridge the gap between White teachers and their historically underprivileged student populations and to understand the rapidly diversifying classrooms in which they will teach.

A Report on Germany as a Study Abroad Destination for U.S. Students in STEM Disciplines
Authors: Comp David 
Published: June 2020

This paper is an attempt to map patterns of study abroad in Germany by American students in the Scientific, Technology, Engineering and Mathematics (STEM) fields and to learn what, if anything, Germany is doing to attract these students to its universities and research institutions. The history of American students studying in Europe, from colonial times to the present day, is studied and details on Germany’s place in this academic activity during this history is examined. Also, the academic trends in the STEM fields in both the United States and German higher education systems is reviewed in order to better understand the international educational opportunities for American students to study these disciplines abroad in Germany.
The Ballet of the Streets: Teaching about Cities at Street Level
Authors: McGuire Pat , Spates Jim 
Published: June 2020

The urban scholar Jane Jacobs once described city life as “the ballet of the streets.” In more than a quarter-century of joint teaching, we have used Jacobs’ metaphor to help our students understand that cities are living organisms created and maintained, for good or ill, by the people who live and work in them. At the heart, our teaching are intense encounters with cities, a “street-level” experience designed not only to give students a chance to walk the city’s streets (especially streets lying far off the beaten path), but to meet its people, prominent and not, so that they can discover for themselves, in living context, the city’s culture, varying life-styles, and issues. Once they learn that cities are people, our longer-term hope is that they will become active in the cities and urban regions which almost assuredly lie in their futures. Given their international importance and astronomical growth over the last half-century, it is arguable that cities are the most significant social systems in the world and, as a result, are crucial for students to understand as cities. The purpose of this paper is to share, first, the methodology we have developed for studying cities “at street level”; and second, to suggest how that methodology might be used in the study of cities anywhere. Starting with a course comparing New York and Toronto, we have used a similar approach to study cities in England, Ireland, Italy, Central Europe, China, and Vietnam.

The paper focuses on the cultural and social foundations of the Holy City of Jerusalem both past and present, and strategies for helping U.S. study abroad students understand these foundations. The City underwent a number of social and cultural transformations from the Islamic and Arab 7thcentury to the present. In evolving from a pilgrimage site to a major walled administrative, religious, and commercial center, Jerusalem began to dominate Palestine’s western coasts, highlands, and the eastern Jordan River valley during the 16thto 19thOttoman centuries. From World War One to the 1948 War, tensions began to build within Palestine and Jerusalem resulting from the British occupation and a dramatic rise in Zionist European Jewish immigrants. The Jewish arrivals were building an independent state within the British colony of Palestine and began to dominate the daily lives of the Palestinians of both the New and Old Jerusalem. With the 1948 establishment of the Jewish State of Israel, the most visible cleavages between Palestinians and Israelis in Jerusalem’s life became apparent with the city literally divided in half with most of the New City occupied by Israeli forces, and the parts of the New and all the Old City by Jordanian soldiers. Various learning strategies are offered to help students grasp some of the intellectual context and cultural riches of today’s “three Jerusalems.”
Trends in Canadian ophthalmology residency match outcomes
Authors: Mah Jeffrey , Kherani Irfan , Hurley Bernard 
Published: June 2020

Background: To date, there exists no formal assessment of the competitiveness of the residency match for Canadian ophthalmology programs. The primary objective of this study was to use Canadian Resident Matching Service (CaRMS) data to describe trends in the number of positions, number of applicants and level of competition for the Canadian ophthalmology match.
Methods: The number of positions and the number of applicants for each ophthalmology program were received from CaRMS for each cycle of the match from 2006-2017. The level of competition was calculated by dividing total number of applicants by the total number of positions in any given year.
Results: The level of competition was consistently high with a median number of 2.0 applicants per anglophone Canadian Medical Graduate (CMG) position, 2.6 applicants per francophone CMG position and 32.5 applicants per International Medical Graduate (IMG) position. Over the study period, the level of competition decreased for francophone CMG and IMG positions and did not change for anglophone CMG positions.
Conclusion: Consistently there are a greater number of applicants than positions for Canadian ophthalmology residency programs and therefore CMG applicants should be encouraged to apply to more than one discipline. The trends in the number of residency positions can be used to update supply projections for ophthalmologists and guide human resource planning.

Abstract
KELT-9 b is an ultra-hot Jupiter transiting a rapidly rotating, oblate early-A-type star in a polar orbit. We model the effect of rapid stellar rotation on KELT-9 b’s transit light curve using photometry from the Transiting Exoplanet Survey Satellite to constrain the planet’s true spin–orbit angle and to explore how KELT-9 b may be influenced by stellar gravity darkening. We constrain the host star’s equatorial radius to be 1.089 ± 0.017 times as large as its polar radius and its local surface brightness to vary by ∼38% between its hot poles and cooler equator. We model the stellar oblateness and surface brightness gradient and find that it causes the transit light curve to lack the usual symmetry around the time of minimum light. We take advantage of the light-curve asymmetry to constrain KELT-9 b’s true spin–orbit angle (

), agreeing with Gaudi et al. that KELT-9 b is in a nearly polar orbit. We also apply a gravity-darkening correction to the spectral energy distribution model from Gaudi et al. and find that accounting for rapid rotation gives a better fit to available spectroscopy and yields a more reliable estimate for the star’s polar effective temperature.

Abstract
In contrast to massive galaxies with solar or super-solar gas phase metallicities, very few active galactic nuclei (AGNs) are found in low-metallicity dwarf galaxies. Such a population could provide insight into the origins of supermassive black holes. Here we report near-IR spectroscopic and X-ray observations of SDSS J105621.45+313822.1, a low-mass, low-metallicity galaxy with optical narrow line ratios consistent with star-forming galaxies but a broad Hα line and mid-infrared colors consistent with an AGN. We detect the [Si vi] 1.96 μm coronal line and a broad Paα line with an FWHM of 850 ± 25 km s−1. Together with the optical broad lines and coronal lines seen in the Sloan Digital Sky Survey (SDSS) spectrum, we confirm the presence of a highly accreting black hole with mass (2.2 ± 1.3) × 106
M
⊙, with a bolometric luminosity of ≈1044 erg s−1 based on the coronal line luminosity, implying a highly accreting AGN. Chandra observations reveal a weak nuclear point source with

erg s−1, ∼2 orders of magnitude lower than that predicted by the mid-infrared luminosity, suggesting that the AGN is highly obscured despite showing broad lines in the optical spectrum. The low X-ray luminosity and optical narrow line ratios of J1056+3138 highlight the limitations of commonly employed diagnostics in the hunt for AGNs in the low-metallicity, low-mass regime.
Exoplanet Detection and Its Dependence on Stochastic Sampling of the Stellar Initial Mass Function

Abstract
Young moving groups (YMGs) are close (<100 pc), coherent collections of young (<100 Myr) stars that appear to have formed in the same star-forming molecular cloud. As such we would expect their individual initial mass functions (IMFs) to be similar to other star-forming regions, and by extension the Galactic field. Their close proximity to the Sun and their young ages means that YMGs are promising locations to search for young forming exoplanets. However, due to their low numbers of stars, stochastic sampling of the IMF means their stellar populations could vary significantly. We determine the range of planet-hosting stars (spectral types A, G, and M) possible from sampling the IMF multiple times, and find that some YMGs appear deficient in M-dwarfs. We then use these data to show that the expected probability of detecting terrestrial magma ocean planets is highly dependent on the exact numbers of stars produced through stochastic sampling of the IMF.
Advection by Large-scale Spiral Flows in Galaxy Clusters
Authors: Naor Yossi , Keshet Uri 
Published: June 2020

Abstract
The intracluster medium of a galaxy cluster often shows an extended quasi-spiral structure, accentuated by tangential discontinuities known as cold fronts (CFs). These discontinuities are thought to isolate between low-entropy, high-metallicity gas inside (i.e., below) the CF that was lifted from the center of the cluster by some radial factor f

i
and high-entropy, low-metallicity gas outside the CF that was pushed inward by a factor f

o
. We find broad support for such a picture, by comparing the entropy and metallicity discontinuities with the respective azimuthal averages, using newly deprojected thermal profiles in clusters A2029, A2142, A2204, and Centaurus, supplemented by deprojected CFs from the literature. In particular, the mean advection factors f

K
and f

Z
, inferred from entropy and metallicity, respectively, strongly correlate (

) with each other, consistent with large-scale advection. However, unlike sloshing simulations, in which the inside/outside phases are an inflow/outflow settling back to equilibrium after a violent perturbation, our results are more consistent with an outflow/inflow, with the fast, Mach

gas inside the CF being a rapidly heated or mixed outflow, probably originating from the cD galaxy, and gas outside the CF being an

, slowly cooling inflow. In particular, entropy indicates an outside advection factor

f
Ko

that is approximately constant in all CFs, gauging the distance traversed by inflowing gas within a cooling time. In contrast,

and

vary considerably among clusters and strongly correlate (

) with the virial mass,

Abnormal myocardial performance index in M-mode color tissue Doppler-echocardiography
Authors: Ivanov Andrey , Runev Nikolay , Manov Emil , Levunlieva Elisaveta 
Published: June 2020

The myocardial performance index (MPI) is used for global systolic-diastolic left ventricular function and prognosis assessment in patients with heart disease, allowing assessment of the patient‘s current condition and disease development follow-up. The classic method of calculation is pulsed Doppler echocardiography. The aim of the study was to evaluate the correlation of myocardial performance index with established left ventricular systolic and diastolic function indices and to determine cut-off values of the myocardial performance index in M-mode color tissue Doppler echocardiography through the aortic and mitral valves predicting abnormal myocardial performance index by pulsed Doppler echocardiography. One hundred and fi ve subjects were studied, including 30 healthy controls, 45 hypertensive patients, and 30 patients with CHD. MPI was calculated using pulsed Doppler (MPIPW) and M-mode color tissue Doppler echocardiography through the aortic (MPIAO1 and MPIAO2) and mitral (MPIMV) valves. In all patients, the myocardial performance index showed a low to moderatenegative correlation with the left ventricular ejection fraction, and the correlation with the diastolic function indices was moderate to high. In healthy persons, the correlations were not signifi cant in almost all comparisons. The MPIAO1, MPIAO2,and MPIMV values predicting abnormal MPI by pulsed Doppler (MPIPW ≥ 0.50) are MPIAO1 ≥ 0.578, MPIAO2 ≥ 0.446, and MPIMV ≥ 0.552. The cut-off values of MPI by M-mode color tissue Doppler echocardiography through the aortic and mitral valve obtained can be used for global left ventricular function assessment in patients with heart disease. Further studies, on a larger number of patients, are necessary to estimate the predictive value of the parameters established.
