The VLT Interferometric Measurements of Active Galactic Nuclei: Effects of Angular Momentum Distributions of Clouds in the Broad-line Region
Authors: Songsheng Yu-Yang , Wang Jian-Min , Li Yan-Rong 
Published: October 2019

Abstract
A few months ago, GRAVITY at the Very Large Telescope Interferometry revealed the structure and kinematics of the broad-line region (BLR) of 3C 273. GRAVITY works with an unprecedented high spatial resolution through spectroastrometry where centers of photons at different wavelengths (λ-photoncenters) of active galactic nuclei are measured by differential phase curves (DPCs) in the wavelength range of the broad Paschenα line. Since Doppler effects govern wavelength shifts of photons sensitively depending on the degree of the ordered rotation (

) of clouds in the BLR, the DPCs are expected to be a function of

. Distributions of the angular momenta of clouds in the BLR could be determined by the formation processes of the BLR; however,

is a totally unknown parameter so far. In this paper, we show that the DPC is sensitive to this free parameter, and

should be taken into account for GRAVITY measurements of the BLR. It is then expected that joint observations of reverberation mapping campaigns and GRAVITY will allow us to obtain complete information about the structure and kinematics of the BLR, including the degree of ordered rotation of clouds, offering an opportunity to reveal the formation of the BLR, either from the tidal capture of clumps in the torus or from winds that developed from accretion disks.

Abstract
We report the discovery of 28 quasars and 7 luminous galaxies at 5.7 ≤ z ≤ 7.0. This is the tenth in a series of papers from the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) project, which exploits the deep multiband imaging data produced by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. The total number of spectroscopically identified objects in SHELLQs has now grown to 93 high-z quasars, 31 high-z luminous galaxies, 16 [O iii] emitters at z ∼ 0.8, and 65 Galactic cool dwarfs (low-mass stars and brown dwarfs). These objects were found over 900 deg2, surveyed by HSC between 2014 March and 2018 January. The full quasar sample includes 18 objects with very strong and narrow Lyα emission, whose stacked spectrum is clearly different from that of other quasars or galaxies. While the stacked spectrum shows N v
λ1240 emission and resembles that of lower-z narrow-line quasars, the small Lyα width may suggest a significant contribution from the host galaxies. Thus, these objects may be composites of quasars and star-forming galaxies.
The Magnetic Flux Rope Structure of a Triangulated Solar Filament

Published: October 2019

Abstract
Solar magnetic flux ropes are core structures driving solar activities. We construct a magnetic flux rope for a filament/prominence observed at 01:11 UT on 2011 June 21 in AR 11236 with a combination of state-of-the-art methods, including triangulation from multiperspective observations, the flux rope embedding method, the regularized Biot–Savart laws, and the magnetofrictional method. First, the path of the filament is reconstructed via the triangulation with 304 Å images observed by the Atmospheric Imaging Assembly on board Solar Dynamics Observatory (SDO) and by the Extreme Ultraviolet Imager on board the twin Solar Terrestrial Relations Observatory. Then, a flux rope is constructed with the regularized Biot–Savart laws using the information of its axis. Next, it is embedded into a potential magnetic field computed from the photospheric radial magnetic field observed by the Helioseismic and Magnetic Imager on board SDO. The combined magnetic field is finally relaxed by the magnetofrictional method to reach a nonlinear force-free state. It is found that both models constructed by the regularized Biot–Savart laws and after the magnetofrictional relaxation coincide with the 304 Å images. The distribution of magnetic dips coincides with part of the filament/prominence material, and the quasi-separatrix layers wrap the magnetic flux ropes, displaying hyperbolic flux tube structures. These models have the advantages of constructing magnetic flux ropes in the higher atmosphere and weak magnetic field regions, which could be used as initial conditions for magnetohydrodynamic simulations of coronal mass ejections.
Multiple Cutaneous Leiomyomas with Uterus Myomatosus (MCUL) – Two Case Reports and One New Mutation of FH Gene
Authors: Koch André , Schönlebe Jacqueline , Vojvodic Aleksandra , Lotti Torello , Wollina Uwe 
Published: October 2019

BACKGROUND: Reed syndrome or multiple cutaneous leiomyomas with uterine leiomyomas are part of the spectrum of heterozygous hereditary disorders with cutaneous, genital and renal manifestations.
CASE REPORTS: We report two female cases of multiple cutaneous leiomyomas with uterine leiomyomas (MCUL) without renal disease, in particular without cysts or papillary renal carcinoma, aged 52 and 55 years, respectively. The diagnosis of pilar leiomyomas was confirmed by histology and immunostaining for smooth muscle actin and desmin. Both females had a hysterectomy in the past because of uterus myomatosus. In one patient, a new mutation of the FH gene was detected, i.e. a heterozygote c1300_1301del (p.Cys434Argfs17) mutation in the exon 9 of the FH gene.
CONCLUSION: Since MCUL shares features with the genetic cancer syndrome hereditary leiomyomatosis and renal cell carcinoma (HLRCC), these patients need a regular follow-up to prevent the late diagnosis of renal cancer.

Agroforesterie et déforestation en République démocratique du Congo. Miracle ou mirage environnemental ?
Authors: Reyniers Camille 
Published: October 2019

Les systèmes d’agroforesterie en savane (manioc/acacia) se généralisent dans les programmes de lutte contre la déforestation en République démocratique du Congo. Sur la base d’une étude de cas dans trois villages du plateau Batéké, l’article identifie trois facteurs influençant l’adoption de ces systèmes dans les milieux ruraux : la raréfaction de la ressource forestière, la dépendance des ménages à l’agriculture comme source de revenu et la sécurité foncière. Il discute ensuite de la capacité de ces systèmes agroforestiers à offrir une transition durable vers des systèmes agraires postforestiers. Classification JEL : D13, Q12, Q23
Les enjeux politiques de l’intelligence artificielle
Authors: Villani Cédric 
Published: October 2019

L’efficacité spectaculaire que l’intelligence artificielle ( ia ) a acquise en fait un enjeu majeur pour la société, qu’elle transformera rapidement. Mais il reste difficile de prédire la profondeur et la vitesse des bouleversements à venir : si l’ambition des experts a évolué en matière de technologie et de stratégie, le monde politique doit s’en emparer avec détermination. La sagesse est d’observer et de favoriser les expérimentations, de former les jeunes et de familiariser l’ensemble de la population avec les nouveaux enjeux. L’Europe, dans la nouvelle guerre froide opposant États-Unis et Chine, doit faire valoir ses atouts, en premier lieu la qualité de sa formation et de sa recherche, souvent méconnues. Tout se jouera sur le développement d’actions audacieuses, sur le dialogue et la concertation qui se mettent en place, notamment au sein du couple franco-allemand, et plus généralement sur l’intégration des expertises européennes, très diverses et encore trop cloisonnées.
Peut-on contenir l’intelligence artificielle ?
Authors: Ganascia Jean-Gabriel 
Published: October 2019

Le terme « intelligence artificielle » renvoie au moins à trois choses bien distinctes : une discipline scientifique, les applications de cette discipline, et les craintes de voir une machine prendre son essor de façon indépendante de nous. Nous montrons ici que seules les applications nécessitent d’être contenues et que cela passe par une réflexion et une éthique permanentes.
L’intelligence artificielle, un danger pour la vie privée ?
Authors: Donnat Francis 
Published: October 2019

Si le règlement général sur la protection des données ( rgpd ) s’applique déjà aux algorithmes afin de garantir un haut niveau de protection de la vie privée, le développement d’algorithmes apprenants, toujours plus autonomes, suppose de l’adapter. Plus de transparence et d’intelligibilité dans le mode de fonctionnement de l’algorithme, la garantie que les données utilisées ne sont pas biaisées, que son fonctionnement est loyal et non discriminant, et enfin que son rôle reste limité à une aide à la décision, sans remplacer l’être humain, qui doit toujours pouvoir garder la main : c’est à quoi il faut répondre pour que les progrès attendus de l’ ia ne se fassent au détriment des valeurs éthiques portées par le droit de l’Union européenne et la législation française.
A Novel Approach to Improve Health Literacy in Immigrant Communities
Authors: Johnson Rhonda M. , Shepard Linda , Van Den Berg Rain , Ward-Waller Chelsea , Smith Polly , Weiss Barry D. 
Published: October 2019

Background:
Anchorage, Alaska, has a large immigrant and refugee population. In fact, it is one of the most ethnically diverse cities in the United States with almost 100 languages spoken by children in the public school system. The city's immigrant and refugee population speaks limited English, and most of these residents are unfamiliar with where or how to obtain health care services through the American health care system.

Brief Description of Activity:
We developed a peer language navigator (PLN) program.

Implementation:
The Anchorage Health Literacy Collaborative developed a community-wide program to address the health literacy needs of the city's immigrant and refugee population. Select people who attended Anchorage's adult literacy program (the Alaska Literacy Program) were chosen to learn about health and wellness topics as well as how to obtain health information from reliable online sources. These people, initially known as PLNs, were then trained to share health information resources with their respective communities.

Results:
A recent evaluation of the program using ripple effects mapping showed that the program has demonstrated wide success, providing understandable health information to hundreds of new English learners throughout the area and guiding them to reliable health and wellness information they can use for themselves, their families, and their community. PLNs have become leaders in their communities and have been renamed peer leader navigators.

Lessons Learned:

For similar programs to be successful, PLNs should be trained using adult learning principles, allowing them to focus on topics and issues of interest to them. The program should link with community organizations to extend the reach of the program. Care must be exercised to avoid overextending or overwhelming PLNs because after they become leaders in their communities, they will receive many requests to provide guidance and education. Finally, when possible, PLNs should be compensated so they can more fully devote their efforts to serving the community.

Plain Language Summary:
The Anchorage Health Literacy Collaborative in Alaska developed a program in which immigrant and refugees attending the city's adult education program to learn beginning English are chosen to serve as peer language navigators (PLNs). The PLNs learn how to obtain credible and easy-to-understand health information and then share it with their respective cultural communities. Lessons learned over time are shared.
Can we improve academic performance and student satisfaction without additional time cost for teachers? Evidence from a blended methodology in Microeconomics
Authors: Erdmann Anett , Torres Marín Alfonso Jesús 
Published: October 2019

<p><strong>Purpose</strong>: The main goal of this paper is to determine if the use of a blended methodology can improve performance and satisfaction of the students, with no additional time cost for teachers. As a second objective, the article attempts to explain observed differences across students in the effect of the methodology on study time based on the theory of optimal decision making. Finally, we sketch a simple cost benefit analysis for the digital learning platform (DLP) used.</p><p><strong>Design</strong>: The teachers combined the traditional classes methodology with the adoption of a DLP in two courses of Microeconomics at an undergraduate level at ESIC Business &amp; Marketing School. Subsequently it is analyzed the impact of this methodology on student satisfaction and performance, as well as on student’s study time using different analytical tools.</p><p><strong>Findings:</strong> students’ grades, at the final exam, increased in a significative way as they spent more time with the DLP and/or when they do more digital assignments at home. Their satisfaction with the blended methodology, and the use of the DLP was quite high for most of students. Their feedback on working time relative to traditional methods showed two extremes, either studying much more or much less. We provide a theoretical explanation for this observation, based on Microeconomic theory. A cost-benefit analysis of the DLP tool at an institutional level suggests that its economic costs are more than justified by the economic benefits of the tool in terms of student’s satisfaction, brand reputation and teachers time saving.</p><p><strong>Contribution:</strong> This document provides a methodology to measure the benefits of an innovative learning methodology using relevant indicators and employing advanced statistical techniques as regression analysis. It also helps us to understand student’s behavior in the face of an educational innovation based on technology. The findings are in line with economic theory.</p>

Semut menyediakan berbagai layanan ekosistem, seperti predasi dan penguraian. Layanan ekosistem semut pada berbagai tipe penggunaan lahan dapat dipengaruhi oleh jenis-jenis semut yang dominan di wilayah tersebut. Tujuan penelitian ini adalah mempelajari pengaruh tipe penggunaan lahan dalam membentuk komunitas semut dan layanan ekosistem yang diberikan. Penelitian ini dilakukan pada empat tipe penggunaan lahan, yaitu hutan sekunder, hutan karet, perkebunan karet, dan perkebunan kelapa sawit di Jambi dari bulan April sampai Juni 2014. Pada setiap tipe penggunaan lahan dibuat empat plot berukuran 50 m x 50 m sebagai ulangan. Semut dikoleksi menggunakan metode pengumpanan dengan larva Corcyra cephalonica (Stainton) yang direkatkan pada piring plastik kemudian diletakkan di permukaan tanah dan batang pohon. Layanan ekosistem semut diukur dengan mengamati larva C. cephalonica yang berhasil diangkut oleh semut dalam waktu satu jam. Hasil penelitian menunjukkan bahwa hutan sekunder memiliki jumlah spesies semut tertinggi dibandingkan dengan tipe penggunaan lahan lainnya. Tipe penggunaan lahan tidak berdampak pada jumlah spesies semut, namun berdampak pada komposisi spesies semut. Pengangkutan larva C. cephalonica terbanyak yang dilakukan oleh semut terjadi di hutan sekunder. Semut yang berperan penting dalam layanan ekosistem sebagai predator pada penelitian ini adalah Achantomyrmex sp. 01, Aenictus sp. 01, Carebara sp. 01, dan Tetramorium sp. 02, Odontoponera denticulata, Tetramorium sp. 03 Crematogaster sp. 02.

Published: October 2019

Burning of crop residues in field include unavailability of labour, high cost in residue removing process and use of combined in rice-wheat cropping system especially in the Indo-Gangetic plains (IGP). Primary crop types whose residues are typically burned include rice, wheat, maize, millet, sugarcane, jute, rapeseed-mustard and groundnut. Farmers in northwest India dispose a large part of rice straw by burning in situ. The ‘rice-wheat cropping system’ is the dominant cropping system in South Asia [1]. This system involves growing rice and wheat in rotation throughout the year where rice and wheat is either grown in the same plot in the same year or in different plots in the same year or in the same plot in different years. Uttar Pradesh, Punjab, Haryana, Bihar, Madhya Pradesh and Himachal Pradesh have the largest areas under this system among the Indian states. Approximately 500-550 Mt of crop residues are produced per year in the country. With a production of 93.9 million tons (Mt) of wheat, 104.6 Mt of rice, 21.6 Mt of maize, 20.7 Mt of millets, 357.7 Mt of sugarcane, 8.1 Mt of fibre crops (jute, mesta, cotton), 17.2 Mt of pulses and 30.0 Mt of oilseeds crops, in the year 2011-12. Emission of greenhouse gases (GHGs) such as carbon dioxide, methane and nitrous oxide causing global warming, loss of plant nutrients such as N, P, K and S, adverse impacts on soil properties and wastage of valuable C and energy rich residues. Black carbon emissions are the second largest contributors to current global warming, after carbon dioxide emissions [2]. Using IPCC emission coefficients, the CH4 released from this source was found to be about 167 Gg [3]. Agricultural crop residues are burnt during the months of October and November every year in the Indo-Gangetic Plains (IGPs) in huge quantities which has a significant impact on greenhouse gas emissions and aerosol loading [4]. In the IGP region of India, 12 million hectares is accounted for rice-wheat crop rotation and harvesting of these crops with combine harvesters is very popular with the farmers of Punjab, Haryana and western Uttar Pradesh [4]. Crop residue management is one of the best options for maintaining the ecological sustainability of farms. There are several options which can be practiced such as composting, generation of energy, production of biofuel, mulching, baling, biochar production and recycling in soil to manage the residues in a productive manner. Conservation agriculture (CA) offers a good promise in using these residues for improving soil health, increasing productivity, reducing pollution and enhancing sustainability and resilience of agriculture.

Published: October 2019

The study was carried out at the farmer fields during Kharif season (2015-16 to 2017-18) in seven villages of four blocks of district Bhagalpur, Bihar. All 54 demonstrations on rice crop were demonstrated in 29 ha area by the active participation of farmers with the objective to show and popularize the improved technologies of rice production (Direct Seeded Rice-DSR) potential developed at Bihar Agricultural University Sabour, Bhagalpur (Bihar). Specifically it examines the changes in farmers’ inputs (labour and materials) and level of productivity and incomes between direct-seeded rice (DSR) and traditionally transplanted rice (TPR) and finally measures the economic return on investment in direct seeding. Analyses included comparison of means of all inputs, cost and return and economic surplus framework. Results revealed that the average yield of all farmers under DSR was 2.60% lower than TPR. However, on comparing the cost of cultivation of DSR farmers with TPR farmers, it was observed that the DSR farmer had (a) higher expenditures on herbicides; (b) lower expenses on fertilizer, fuel, and rent cost for land preparation and (c) lower labour costs for seedbed preparation and care, crop establishment and fertilizer application. In this way the sum of the total cost of cultivation in DSR was reduced by Rs. 8941 /ha than TPR. DSR also recorded the maximum net return (Rs. 42857/ha) and benefit: Cost ratio (2.95).
On the basis of above findings it may be concluded that the DSR method of rice cultivation is more economical than TPR as it reduced the cost of cultivation by 37.9% and gave maximum net return as well as benefit cost ratio.

Climate change has much impact on regular drought and flood conditions of India, in result it influence agriculture. Agriculture is major means of livelihood and nearly 80 per cent of rural population of India depend on it. But this profession is not being sustainable for the livelihood because of regular flood and drought situation which results in migration of rural youth. Some main causes of migration of the rural youth to the urban areas are lack of economic incentives coupled with other factors like less opportunities for employment and lack of infrastructure for education. Human population can migrate as both interstate as well as intrastate for establishing a new permanent or semi- permanent residence. During 2001 census the total number of migrants was 314 million by the last residence. Out of which 85% of the migration was intrastate. While 13% of migration was residences interstate. About 20 million people had migrated from rural areas to urban areas.
