Preliminary Results of Virtual Reality Mapping of E+A Galaxies and Candidates in Nearby Rich Clusters of Galaxies
Authors: Liu Allen G. , Liu Charles T. 
Published: April 2021

Abstract
In the study of large astronomical data sets, virtual reality (VR) can help build valuable spatial intuition for scientific discovery. We created VR visualizations of E+A galaxies and candidates in four nearby clusters of galaxies: Leo, Virgo, Hercules, and Coma. E+A's are a type of post-starburst galaxy in which all star formation has been recently (∼1 Gyr ago) quenched. Our E+A samples were assembled and cataloged by the Y/Dim collaboration through visual and quantitative analysis of SDSS DR16 spectra. The visualizations are designed for Oculus VR headsets, and utilize C# scripts which interface with the Unity engine, including public domain code and code developed by the lead author. We use these visualizations to find features of the aforementioned galaxy clusters: for instance, a “nose” of low velocity objects in the center of the Virgo cluster and a collection of E+A candidates along a galactic filament in the Coma cluster.

Abstract
We present 46 HW Virginis Post-Common Envelope Binary Systems identified by the Zwicky Transient Facility, 26 of which appear to be new discoveries. Through the application of the Box Least-Squares Algorithm to ZTF data, we searched a data set of 17,473 systems for periodicity and phase-folded all of the ZTF lightcurves of the objects at their best period. Through visual analysis of these phase-folded lightcurves, we identified the 46 HW Vir Systems.

relation at redshifts 0.08 < z < 1.53. We use a set of 111 radio-selected AGN at 3 GHz VLA-COSMOS within the X-ray galaxy groups in the COSMOS field. We compare these results to those for 171 star-forming galaxies (SFGs), using the theoretical relation of Moster et al. We find that AGN agree within 1% with the Moster et al. relation, SFGs show an offset of 37%, suggesting that the radio-mode feedback from AGN at a median redshift of ∼0.5 still plays a significant role in the

SED Machine Spectra for HO Puppis and V722 Tauri
Authors: Ngeow Chow-Choong , Lee Chien-De , Coughlin Michael W. , Laher Russ R. 
Published: April 2021

Abstract
We present low-resolution spectra collected with the Spectral Energy Distribution Machine (SEDM) for an IW And-type dwarf nova, HO Puppis, and a Be star, V722 Tauri. The SEDM is an integrated field unit spectrograph mounted on the 60 inch telescope at the Palomar Observatory, with a spectral resolution of R ∼ 100 in the optical wavelength range. The Hα emission line was clearly detected for the bright Be star V722 Tauri at ∼12.5 mag, but barely detected in the spectra for the ∼13.7 mag HO Puppis. Our SEDM observations could be used as guidance for observing similar objects with the SEDM, as well as other R ∼ 100 spectrographs, in the future.
Accretion Belt Characteristics in a Hydrodynamic Evolution of a Contact Binary
Authors: Barnett Elliot T. , Motl Patrick M. 
Published: April 2021

Abstract
We compare features from the circulation model developed in Stȩpień for contact binaries to a long-term hydrodynamical evolution of a symmetric contact binary. The numerical evolution is fully three-dimensional and begins from an equilibrium structure in contact at one grid cell. As the evolution is conducted with Flow-ER, an explicit hydrodynamics code for self-gravitating fluids, we are not able to address energy transport or evolution on a thermal timescale. However, we are able to investigate the width and height of the equatorial accretion belt and the flow of material in and out of the inner Lagrange point. The flow of material between the two components arises quickly in the evolution and does not change significantly through tens of orbital periods. As the stellar components are modeled as polytropes of index 3/2 a slight numerical mass imbalance causes one component to only gain mass over the course of the simulation leading eventually to a dynamical merger of the contact binary.

Abstract
In the last decade, exoplanets space missions started to collect a huge amount of photometric observations, with over ∼1,000,000 new light curves generated every month from the Transiting Exoplanet Survey Satellite (TESS) full-frame images alone. In order to analyze such an unprecedented volume of data, automated planet-candidate detection has become an appreciable replacement to human vetting. In this work, we present a Machine Learning approach, based on Deep Neural Networks, to perform a binary classification of TESS light curves in terms of planet candidate and not-planet. Since few TESS labeled data exist to date, we pre-train the network with Kepler DR24 data set, including ≳15,000 labeled light curves. Our pre-trained model is then tested on ExoFOP data, showing an appreciable gain in terms of reliability with respect to a randomly initialized model.

Published: April 2021

Introduction: At the end of 2019, the COVID-19 broke out, and spread to Guizhou province in January of 2020.
Methodology: To acquire the epidemiologic characteristics of COVID-19 in Guizhou province, we collected data from 169 laboratory-confirmed COVID-19 related cases. We described the demographic characteristics of the cases and estimated the incubation period, serial interval and the effective reproduction number. We also presented two representative case studies in Guizhou province: Case Study 1 was an example of the asymptomatic carrier; while Case Study 2 was an example of a large and complex infection chain that involved four different regions, spanning three provinces and eight families.
Results: Two peaks in the incidence distribution associated with COVID-19 in Guizhou province were related to the 6.04 days (95% CI: 5.00 – 7.10) of incubation period and 6.14±2.21 days of serial interval. We also discussed the effectiveness of the control measures based on the instantaneous effective reproduction number that was a constantly declining curve.
Conclusions: As of February 2, 2020, the estimated effective reproduction number was below 1, and no new cases were reported since February 26. These showed that Guizhou Province had achieved significant progress in preventing the spread of the epidemic. The medical isolation of close contacts was consequential. Meanwhile, the asymptomatic carriers and the super-spreaders must be isolated in time, who would cause a widespread infection.

Introduction: Infections caused by extensively-drug resistant (XDR) and pan-drug resistant (PDR) Klebsiella pneumoniae represent an emerging threat due to the high associated mortality. This study aimed to characterize two carbapenem resistant K. pneumoniae strains from the same patient, the first being PDR (referred to as IMP 1078b) and the second being XDR (referred to IMP 1078s) isolated from the same patient.
Methodology: Antimicrobial susceptibility testing was done for the 2 K. pneumoniae isolates, followed by carbapenem/β-lactamase inhibitor combination assay, and fitness cost against cefepime and meropenem. Then, whole-genome sequence analysis was performed to decipher the molecular mechanisms behind the high level of resistance recorded in both isolates. Finally, qRT-PCR was done for β-lactam resistant genes.
Results: This is the first report about a K. pneumoniae isolate harboring 47 antimicrobial resistance genes and having type IV pilli (Yersinia) and the fimbrial adherence determinant Stb (Salmonella) as virulence factors. Further analysis on both isolates are discussed within the article.
Conclusion: The co-existence of a high number of antimicrobial resistant (AMR) genes and virulence factor genes may lead to a life threatening invasive and untreatable infection.
Une parole déplacée
Authors: Legrand Dorothée 
Published: April 2021

Il s’agit de venir parler : non seulement parler, mais venir, se déplacer, psychiquement, se déplacer assez pour suspendre un moment le silence et le hurlement du monde – pour s’entendre le dire et ainsi y changer fondamentalement sa place. Ce déplacement ne va pas sans corps. Alors, qu’en reste-t-il quand nos corps sont confinés ? Pas seulement une présence corporelle résiduelle, mais aussi un autre corps : un corps qui se déploie comme le lieu d’où la parole s’élève. Il s’agit donc de l’écouter – pour ne pas, cet autre corps, le confiner.
Assessment of quality of life and psychiatric morbidity in patients undergoing hemodialysis at a tertiary care center
Authors: Endreddy Ananda Reddy , Chennareddy Lakshmi Rajesh , Shaik Subahani 
Published: April 2021

Background:
Hemodialysis is a procedure performed in persons who suffer from acute/chronic renal failure or who have end-stage renal disease. Due to disabilities caused by renal disease and the continuous requirement of dialysis, it is frequently associated with comorbid psychiatric disorders, which in turn adversely affects the quality of life (QOL) of patients.

Aims and Objectives:
Our study was conducted with the objectives of estimating the proportion of psychiatric comorbidities and the QOL among the patients who were on hemodialysis.

Materials and Methods:
A cross-sectional study was done on a total of fifty consecutive patients undergoing dialysis in the hemodialysis unit, Department of Nephrology, Narayana Medical College and Hospital. A semi-structured questionnaire was used to obtain the sociodemographic details, history including details of illness, dialysis, and medical comorbidities. The presence of psychiatric comorbidities was assessed using Mini-International Neuropsychiatric Interview. The WHOQOL-BREF Scale was used to assess the QOL and the Modified Kuppuswamy Socioeconomic Scale was used to assess the socioeconomic status.

Results:
Psychiatric comorbidities were observed in 80% of the patients undergoing hemodialysis. Among the psychiatric comorbidities, major depressive disorder was found in 54%, dysthymia in 14%, and generalized anxiety disorder in 12% of the patients. History of diabetes was found in 80% of the patients and history of hypertension was found in all the patients in the study. Among the patients, a significant association was observed between the psychiatric comorbidities and the score in all the four domains of the WHOQOL-BREF Scale.

Conclusions:
Our study concludes that the majority of the patients were found to have psychiatric comorbidities. On the WHOQOL-BREF Scale, all the four domains in QOL were significantly associated with psychiatric morbidity.
Is it a myth to perform blind apical wedge resection in primary spontaneous pneumothorax surgery to improve recurrence rates?
Authors: Vayvada Mustafa , Tezel Yelda , Tezel Çağatay 
Published: April 2021

Background:
Video-assisted thoracoscopy surgery (VATS) is the first method for the surgical treatment of primary spontaneous pneumothorax (PSP). Many surgeons traditionally performed bullectomy or wedge resection (WR) in addition to mechanical or chemical pleurodesis. Our study aimed to determine whether WR was necessary without seeing bleb or bullae during the surgery.

Methods:
Patients with no bleb or bullae detected during surgery were included in the study. Apical pleurectomy was performed in all cases. The patients were divided into two groups as WR and non-WR. The minimum follow-up period was 24 months. Medical records of patients were evaluated retrospectively. Patients who could not be followed up were excluded from the study.

Results:
A total of 104 surgical treatments of PSP were performed, WR was not performed in 70 cases (67.3%). The surgical time was statistically significantly longer in the WR group than in the non-WR group. There was no statistically significant difference between the two groups in terms of drainage amount, drain removal time, length of hospital stay and bleeding requiring thoracotomy. Prolonged air leak was more common in the non-WR group than in the WR group (7.1% vs. 2.9%; P = 0.661). There was no difference in the rate of recurrence in either group. Recurrence was 2.9% (1/34) in the WR group and 2.9% (2/70) in the non-WR group.

Conclusion:
In VATS of PSP, blind apical WR without bleb or bullae reduced prolonged air leakage but did not contribute to lowering the rate of pneumothorax recurrence.
Neue Tendenzen im Bildungssystem der deutschen Minderheit in Ungarn
Authors: Brenner Koloman 
Published: April 2021

Die deutsche Minderheit in Ungarn gehört zu den relativ großen deutschen Gemeinschaften in Ost-Mittel-Europa, die eine lange historische Entwicklung vorweisen kann. Im heutigen Ungarn gibt es drei größere Siedlungsgebiete, wo Angehörige der deutschen Minderheit in höherer Anzahl leben: Westungarn entlang der österreichischen Grenze, das Ungarische Mittelgebirge (vom Ofner Bergland bis zum Plattensee-Oberland) mit den Zentren Ofen/Buda und Zirc bzw. Südungarn mit dem Zentrum Fünfkirchen/Pécs. Der Aufsatz stellt die neuen Tendenzen im Bildungsbereich und ihre Rolle im Revitalisierungsprozess der deutschen Sprache und Kultur der betroffenen nationalen Minderheit in Ungarn dar. Dies ist auch deswegen eine relevante Fragestellung, weil im Vergleich mit anderen deutschen Minderheiten in Ost-Mittel-Europa, der deutsche Fremdsprachenunterricht und auch der Unterricht von Deutsch als Minderheitensprache eine spezifische Entwicklung vorweisen kann.
Die Landesselbstverwaltung der Ungarndeutschen, als gewähltes Organ der Ungarndeutschen hat das Ziel, ein System von selbst getragenen Minderheiteninstitutionen aus- und aufzubauen. Aktuell konnten schon in über 50 Fällen die örtlichen Deutschen Selbstverwaltungen Kindergärten und Grundschulen in eigene Trägerschaft übernehmen, die ersten Erfahrungen widerspiegeln einen vorsichtigen Optimismus und es ist zu hoffen, dass in den nächsten Jahren auch die inhaltliche Arbeit in diesen Bildungsinstitutionen immer mehr der Zielsetzung der Neubelebung der deutschen Sprache und Kultur dienlich sein wird.
Cestode infections of two clariid and two claroteid catfish species in River Galma, Zaria, Nigeria
Authors: Ibrahim Z.A. , Aken’Ova T. , Luka S.A. 
Published: April 2021

Four catfish (Siluriformes) species comprising two clariids, Heterobranchus bidorsalis (65) and Heterobranchus longifilis (15) and two claroteids, Auchenoglanis occidentalis (31) and Chrysichthys auratus (19) from River Galma Zaria, Nigeria, were examined for gastrointestinal cestodes between May 2016 and February 2017. Helminths recovered were stained, dehydrated, cleared and mounted in Canada balsam for microscopic examination. A total of seven cestode species were recovered from the clariids and claroteids. The cestodes were distributed among the fish examined as follows: in C. auratus: Wenyonia longicauda (26.32%), W. virilis (10.53%), and W. minuta (5.26%); in H. bidorsalis: W. acuminata (3.08%), W. virilis (18.46%), Monobothrioides woodlandi (6.15%), Proteocephalus sp. (1.54%) and Tetracampos ciliotheca (4.62%); in H. longifilis: M. woodlandi (6.67%), W. longicauda (6.67%) and W. acuminata (6.67%). Prevalence of cestode infection in C. auratus was higher in the wet than in the dry season; however, prevalence of infection in H. longifilis and H. bidorsalis was higher in the dry than in the wet season. The prevalence was higher in male than in female H. longifilis while higher in female than in male C. auratus and H. bidorsalis. Prevalence decreased with increase in standard length of C. auratus, H. longifilis and H. bidorsalis. A seemingly posteriorly deformed W. minuta was recovered from C. auratus. None of the 31 A. occidentalis examined in this study was infected by cestodes. All the fish used in this study were collected mostly on the basis of availability. It is therefore recommended that larger sample of assorted sizes be obtained, especially of H. longifilis (15) and C. auratus (19), of which very few specimens were examined during the period of this study to obtain a clearer picture of infection by the cestodes from RiverGalma, Zaria, Nigeria.

Published: April 2021

Skin is a very important and sensitive part of the human body. It is directly related to the outside world. In everyday life, the skin plays an important role. One of its functions is to remove waste substances. The lack of knowledge and limited sources of information causes low public awareness of skin health as well as not seeing a doctor. Regular skin checks can overcome the beginning of skin diseases that might trigger other more dangerous diseases. The system in this study is designed to detect and to know the symptoms of facial skin diseases that are felt. This knowledge-based system design was developed to diagnose human facial skin disease using the dempster shafer method. The results can help detecting earlier facial skin diseases and overcoming them.

Milk price modeling and forecasting
Authors: Shyian Nataliia , Moskalenko Valentyna , Shabinskyi Olexandr , Pechko Volodymyr 
Published: April 2021

Purpose. The purpose of the article is to substantiate the methodological approach to forecasting the selling price of milk, which is produced and sold by agricultural producers in the Ukrainian market of raw milk.
Methodology / approach. The basis of the methodological approach is the construction of models describing the change in sales prices for milk and certain types of dairy products (pasteurized milk with a fat content of up to 2.5 %, sour cream with a fat content of up to 15.0 %, soft fat cheeses) during 2017–2019 and forecasting the sale price of milk for a period of 6 months. The ARIMA model was used in the forecast, taking into account the degree of correlation between changes in the price of milk and the analyzed types of dairy products. The time factor (time lag) of one month and the share of milk in the price of the finished dairy products were also considered.
Results. The forecast results allowed us to determine milk sales prices for January–June 2020. In addition, the study showed the lack of a single direction in their change during the bias period, namely – increase in milk sales price during February–January 2020 and its reduction till June 2020. The obtained forecast values of milk selling price, considering the share of milk in the selling price of finished dairy products, were adjusted according to the time lag.
Originality / scientific novelty. Novelty is an algorithm for using a methodical approach to forecasting the purchase price of milk, taking into account the correlation between milk prices and prices for certain types of dairy products; time lag and the share of milk prices in the sale price of finished dairy products.
Practical value / implications. Comparison of the obtained forecast data of the price with the actual prices of milk sales indicated the existence of insignificant differences between them, proving the adequacy of the proposed methodological approach to be used in forecasting of milk prices at the enterprises.
