Abstract
The high-quality light curves from the Transiting Exoplanet Survey Satellite (TESS) represent a unique laboratory for the study of stellar rotation, which is a fundamental observable driving stellar and planetary evolution, including planetary atmospheres and impacting habitability conditions and the genesis of life around stars. As of 2020 April 14, this mission delivered public light curves for 1000 TESS objects of interest (TOIs), observed with a 2 minute cadence during the first 20 months of the mission. Here, we present a search for rotation signatures in these TOIs, using fast Fourier transform, Lomb–Scargle, and wavelet techniques, accompanied by a rigorous visual inspection. This effort revealed 163 targets with rotation signatures, 131 of which present unambiguous rotation periods ranging from 0.321 and 13.219 days, whereas 32 of them present dubious rotation periodicities. Of these stars, 109 show flux fluctuations whose root cause is not clearly identified. For 714 TOIs, the light curves show a noisy behavior, corresponding to typically low-amplitude signals. Our analysis has also revealed 10 TOI stars with pulsation periodicities ranging from 0.049 to 2.995 days and four eclipsing binaries. With upcoming TESS data releases, our periodicity analysis will be expanded to almost all TOI stars, thereby contributing in defining criteria for follow-up strategy itself, and the study of star–planet interactions, surface dynamic of host stars, and habitability conditions in planets, among other aspects. In this context, a living catalog is maintained on the Filtergraph visualization portal at https://filtergraph.com/tess_rotation_tois.

Abstract
The recent detection of a neutron star merger by the LIGO collaboration has renewed interest in laboratory studies of r-process elements. Accurate modeling and interpretation of the electromagnetic transients following the mergers requires computationally expensive calculations of both the structure and opacity of all trans-iron elements. To date, the necessary atomic data to benchmark structure codes are incomplete or, in some cases, absent entirely. Within the available laboratory studies, the literature on Au i and Au ii provides incomplete reports of the emission lines and level structures. We present a new study of Au i and Au ii lines and levels by exposing a solid gold target to plasma in the Compact Toroidal Hybrid (CTH) experiment at Auburn University. A wavelength range from 187 to 800 nm was studied. In Au i, 86 lines are observed, 43 of which are unreported in the literature, and the energies of 18

levels and 16 of the 18 known

levels are corroborated by a least-squares level energy optimization. In Au ii, 76 emission lines are observed, and 51 of the lines are unreported in the literature. For both Au i and Au ii, the new lines predominantly originate from the most energetic of the known levels, and over half of the new Au ii lines have wavelengths longer than 300 nm. For the estimated electron parameters of CTH plasmas at the gold target (n
e ∼ 1012 cm−3, T
e ∼ 10 eV), two-electron transitions are similar in intensity to LS-allowed one-electron transitions.
Upgraded GMRT Observations of the Coma Cluster of Galaxies: The Observations
Authors: Lal Dharam V. 
Published: September 2020

Abstract
We have used the upgraded Giant Metrewave Radio Telescope to map the Coma cluster of galaxies at 250–500 MHz and 1050–1450 MHz bands. These 6.″26 and 2.″18 resolutions observations allow detailed radio structures to be determined of all detected radio sources that show both discrete pointlike and extended morphologies. We present images of a subset of 32 brightest (S

ν
≳ 30 mJy) and dominant sources, and several sources show discrete pointlike radio morphologies. We find the steepening of the spectra consistent with synchrotron cooling in the majority of sources and the median for spectral indices is −0.78, suggesting that ∼59% sources have steep spectra. The nature and the statistical properties of the radio sources in the Coma cluster will be discussed in subsequent papers.

Abstract
We present a study of ultracompact dwarf (UCD) galaxies in the Virgo cluster based mainly on imaging from the Next Generation Virgo Cluster Survey (NGVS). Using ∼100 deg2 of u*giz imaging, we have identified more than 600 candidate UCDs, from the core of Virgo out to its virial radius. Candidates have been selected through a combination of magnitudes, ellipticities, colors, surface brightnesses, half-light radii, and, when available, radial velocities. Candidates were also visually validated from deep NGVS images. Subsamples of varying completeness and purity have been defined to explore the properties of UCDs and compare to those of globular clusters and the nuclei of dwarf galaxies with the aim of delineating the nature and origins of UCDs. From a surface density map, we find the UCDs to be mostly concentrated within Virgo’s main subclusters, around its brightest galaxies. We identify several subsamples of UCDs—i.e., the brightest, largest, and those with the most pronounced and/or asymmetric envelopes—that could hold clues to the origin of UCDs and possible evolutionary links with dwarf nuclei. We find some evidence for such a connection from the existence of diffuse envelopes around some UCDs and comparisons of radial distributions of UCDs and nucleated galaxies within the cluster.

Parlement et réjouissances monarchiques à Paris au XVIII e siècle : mécanique et intérêt d’une joie décrétée
Authors: Valade Pauline 
Published: September 2020

Au cours du xviii e siècle, le Parlement de Paris constitue un pilier fondamental dans la légalisation des réjouissances monarchiques. Grâce au Parquet, un arrêt réglementaire conditionne les participations de chacun à la joie publique. Toutefois, les magistrats ont quelquefois manifesté un zèle déplacé dans la manière d’en appeler aux manifestations de joie publiques. Pour la Cour souveraine, il s’agissait d’un moyen de faire valoir leur importance dans l’administration monarchique, à l’heure où le souverain comptait de plus en plus sur les autorités de la Ville. En tant que détenteur de la « Grande Police », le Parlement engagea un conflit latent entre d’une part l’autorité des magistrats et, d’autre part, le roi et la Ville. L’instruction du procès à la suite du drame parisien le 30 mai 1770 en constitue le meilleur exemple.
Pavement et enduits peints du Haut-Empire, rue É. Herriot à Narbonne
Authors: Sabrié Raymond 
Published: September 2020

Dans la périphérie nord-est de la ville antique de Narbonne, un sondage limité a permis la découverte d’une mosaïque et de quelques enduits peints. Le pavement appartenant à un premier état antérieur au milieu du ier siècle est partiellement conservé. Il représente un damier noir et blanc, les cases blanches étant chargées d’un carré noir inscrit. Quelques enduits peints très fragmentaires, qu’on peut rattacher à un deuxième état, ont été prélevés dans la couche de destruction. Les éléments de décor à fond blanc, guirlandes, compartiments, ornent la zone supérieure d’une paroi. Une petite construction avec des éléments de clôture constitue une originalité. Les décors réalisés à la fin du iie siècle ont été détruits lors de l’abandon du quartier dans le courant du iiie siècle.
Impact of Cash Deals and Related Industry Merger on Synergies Gains: A Case of Indian M&A
Authors: Kalsie Anjala , Singh Neha 
Published: September 2020

A firm's financial attributes play an essential part in the merger decision. The present paper attempts to improve the existing literature on assessing M&A activity in Indian corporate. This research paper aims primarily to analyze the (a) Synergies realized when the mode of payment in the merger deal is cash, (b) impact on bidder liquidity when payment is made in cash (c) Synergies realized when both target and acquirer in the deal belong to related industry, i.e. the merger is horizontal and (d) assess the impact on bidder leverage when payment is made in equity. The paper has analyzed a panel of 120 major Indian M&A deals from 2005 to 2015, having three years of data pre and post-merger. Instrument Variable Probit Regression analysis has been employed in the study. The key results from the analysis show that in case of payment method in the deal being cash, M&A appears financially favorable for the bidder companies. The results of the empirical analysis of the study do support the generation of synergies in the case of horizontal mergers. The combined firm has also found to have lower liquidity for Indian Mergers & Acquisitions. Significant results have also been obtained for the leverage variables indicating fewer borrowings for the merged firm.

Competing Nationality Politics Targeting German Communities at the Hungarian-Romanian Border Zone after the Great War
Authors: Szilágyi Levente 
Published: September 2020

In my study, I focus on the events that took place in the short period after the Great War ended (1918) and before the consolidation of Romanian power in the Hungarian-Romanian Border Commission (1922) from the point of view of the artificially created ethnic category: the Satu Mare Swabians or Sathmar Swabians. The historiography related to the “ethnographic” aspects of these events have appeared multiple times and in several contexts and forms in the years since. However, the question of ethnicity has not arisen in relation to the population of German descent, but rather in relation to the Hungarian-speaking Greek Catholic communities of Romanian and Rusyn/Ruthenian origin who were treated by the Romanian side as Magyarized Romanians. Following this example, the Romanians later began to collect data on the Magyarized Germans, which they then presented to the Border Commission. Germans living in the territory witnessed a strong competition between identity politics and discourse supported by rival Hungarian and Romanian states. One of the key features of this rivalry was the intensive propaganda activity promoted by both the Romanian and the Hungarian authorities to gain territories to the detriment of the other.

The Resistance Movement is a movement that is very typical of the rejection of policies or changes made in an area in which there are humans in it. There are two categories of actors involved in the resistance movement, namely the policy maker and the recipient of the policy. The identity of the perpetrators depends on the case and the location of the case which contains different human characteristics or human communities. The research uses literature review as preparation material for the Government of Indragiri Hilir Regency in dealing with resistance movements.
This journal is the result of qualitative research which will explain theoretically the resistance movement. Resistance movement is the movement of a party in making a rejection or resistance to the policy to be made or already made. The results of this study can be used as a discussion of Indragiri Hilir Regency Government in making policies and dealing with resistance movements.
This research concludes that poor communication and socialization can spark a desire to resist. The resistance movement becomes stronger when the policy maker is unable or slow in responding to the complaints of the recipient of the policy. Regardless of whether the complaint is wrong or right, rapid response must be done quickly so that there is no misunderstanding
that causes greater resistance. The policy makers must identify the causes of resistance because the causes are the basic foundation in developing strategies for handling and resolving conflicts in this resistance movement. So that it can be said that each cause has its own handling strategy.
Una propuesta para homogenizar la escritura y el uso de nombres comunes en mastozoología

Published: September 2020

El sistema de clasificación binomial de Carlos Linneo (Species plantarum, 1753 [para la Botánica] y la décima edición de Systema Naturae, 1758 [para la Zoología]), vino a llenar un gran vacío en la ciencia, al nombrar de forma sistemática a las plantas y animales,universalizando de este modo la comunicación científica (Stearn 1959, McGregor 2009, Comisión Internacional de Nomenclatura Zoológica 1999). Este sistema de clasificación tiene la gran ventaja de ser común a todos los científicos del planeta y permite consistencia sin importar el idioma. Sin embargo, gran parte del conocimiento de las especies, en especial de mamíferos, proviene del conocimiento popular y de las comunidades que siempre han estado en contacto directo con las áreas naturales.

Creating Transformative Spaces in Education: Facing Humanity, Facing Violence
Authors: Todd Sharon 
Published: September 2020

This paper considers the difficulties that accompany projects in education variously configured around a multicultural or intercultural label, particularly when they are built upon, for example, idealised conceptions of humanity, notions of the common good and dialogue, or ideas of recognition. My premise here is that, while such idealisations may be constructed with the best of intentions, they occlude discussions of how to face the violent realities that can also be part of social interaction. My focus here is on the existential conditions that frame our encounters with other people, and how such existential concerns lead us to confront more openly the violence that can inhere in such encounters. Beginning from this existential position, I argue, actually invites alternative ways of formulating transformative work in education, namely a focus on the present. Secondly, I turn to explore the transformative spaces created by performance artist Marina Abramovic, and how her projects reveal what we are up against existentially when it comes to facing humanity in the here and now, in all its messiness. And, finally, I make the suggestion that an education committed to the existential conditions of facing humanity can be built on a reconceptualization of conversation, as opposed to dialogue. Here I argue that conversation offers the kind of potential for transformation in its open-endedness and anarchic sensibilities.
Indexical Ways of Knowing: An Inquiry Into the Indexical Sign and How to Educate for Novelty
Authors: Campbell Cary 
Published: September 2020

In this paper, I propose that the indexical sign can be used to derive a model for active (touching-and-feeling) learning. The implicit processes involved in the subtle reading of indices contain explanatory possibilities for understanding how students adapt to novelty in the learning process. Besides looking at how indexicality functions in human ontogeny and cognition, I will also examine the human capacity for modeling our world through aggregations of systems of representations (Sebeok, 1994). Modeling systems (with their implicit recognition that the human is a semiotic animal) help us to conceptualize how novelty is assimilated in the learning process. I posit that how we come to terms with new experiences (and new stimuli generally) is of an indexical nature. I am specifically referring to the site where "the new" comes from the outside (like a rain cloud signaling the coming storm) and acts upon us. We can recognize the rain cloud as an experiential pattern (as a semiotic entity) or not; the rain is still going to bear down on us regardless of the success of our interpretations. This existential realness of indexical signs is precisely their power to function as a pedagogical tool, to help us assimilate and accommodate to novel stimulus. The concept of modeling helps us conceptualize the process in which the new stimulus is absorbed and integrated into our cultural/semiotic systems. In short, this paper aims to explore what I call the indexical rub of learning; that initial friction or resistance felt when meeting a new experience. My hope is that this exploration can aid in the cultivation of a mindset in teachers, students and researchers that does not fear this resistance, but can use it to propel positive absorption (in the Deweyian sense) and engaged learning.
Evaluation of different culture media to support in vitro growth and biofilm formation of bacterial vaginosis-associated anaerobes
Authors: Rosca Aliona S. , Castro Joana , Cerca Nuno 
Published: September 2020

Background
Bacterial vaginosis (BV) is one of the most common vaginal infections worldwide. It is associated with the presence of a dense polymicrobial biofilm on the vaginal epithelium, formed mainly by Gardnerella species. The biofilm also contains other anaerobic species, but little is known about their role in BV development.

Aim
To evaluate the influence of different culture media on the planktonic and biofilm growth of six cultivable anaerobes frequently associated with BV, namely Gardnerella sp., Atopobium vaginae, Lactobacillus iners, Mobiluncus curtisii, Peptostreptococcus anaerobius and Prevotella bivia.

Methods
A total of nine different culture media compositions, including commercially available and chemically defined media simulating genital tract secretions, were tested in this study. Planktonic cultures and biofilms were grown under anaerobic conditions (10% carbon dioxide, 10% helium and 80% nitrogen). Planktonic growth was assessed by optical density measurements, and biofilm formation was quantified by crystal violet staining.

Results
Significant planktonic growth was observed for Gardnerella sp., A. vaginae and L. iners in New York City III broth, with or without ascorbic acid supplementation. Biofilm quantification showed high in vitro biofilm growth for Gardnerella sp., P. anaerobius and P. bivia in almost all culture media excluding Brucella broth. Contrary, only New York City III broth was able to promote biofilm formation for A. vaginae, L. iners and M. curtisii.

Conclusions
Our data demonstrate that New York City III broth relative to the other tested media is the most conducive for future studies addressing polymicrobial biofilms development as this culture medium allowed the formation of significant levels of single-species biofilms.
