Kegiatan pengabdian kepada masyarakat ini bertujuan: (1) memberikan keterampilan softskill public speaking; (2) memberikan pengetahuan literasi media bagi remaja di Kelurahan Sungai Sibam. Kegiatan ini bermula dari fenomena perkembangan internet memberikan pengaruh yang cukup besar bagi masyarakat, terutama bagi remaja. Internet saat ini sudah menjadi kebutuhan pokok bagi setiap orang. Setiap hari anak-anak dan remaja di lingkungan sungai Sibam, banyak menghabiskan waktu untuk bermain internet. Kegiatan ini biasa dilakukan baik melalui gadget maupun di warung internet (warnet) yang saat ini tersebar banyak di berbagai sudut di permukiman warga. Kondisi ini yang menjadikan keresahan bersama bagi setiap orang tua. Kesibukan orang tua bekerja tidak lagi dapat mengontrol kegiatan anak-anak remaja sepulang sekolah. Padahal konten media internet menyuguhkan berbagai informasi baik yang bersifat positif maupun negatif. Kegiatan yang telah dilakukan terdiri dari dua program yakni seminar literasi media dan pelatihan public speaking. Seminar literasi media dilakukan bersamaan dengan kegiatan pelatihan penulisan. Dalam kegiatan ini juga dilakukan praktik menulis di mading (majalah dinding). Kegiatan dilanjutkan pelatihan public speaking. Luaran dari program PKMS ini berupa peningkatan softskill remaja terhadap literasi media, dan public speaking.

All selected galaxies in our sample are spectroscopically observed by the fourth generation of SDSS/Mapping Nearby Galaxies at Apache Point Observatory (SDSS-IV/MaNGA) integral field spectroscopy survey.

Published: May 2020

Abstract
We present a long temporal baseline variability survey in the Frontier Field MACSJ1149. In this study, we identify active galactic nuclei (AGNs) and other transient sources via their variability using over a decade of Hubble Space Telescope (HST) images for thousands of galaxies in the cluster region and detect significant variability in galaxies extending down to an apparent nuclear magnitude of m

i
< 26.5. Our analysis utilizes HST images obtained in six different wavelengths from 435 nm to 1.6 microns and covers timescales 12 hr to 12 yr apart. We find that ∼2% of galaxies in these images are variable, with 49 AGN candidates and 4 new supernovae candidates detected. Half of the variables are in the cluster and these are primarily elliptical galaxies displaying variability only in the near-infrared bands. About 20% of the AGN candidates have morphologies and colors consistent with quasars, though most of the variables appear to be dominated by the host galaxy light. The structure function for these sources shows a greater amplitude of variability at shorter wavelengths, with slopes shallower than typical quasars. We also report a previously unknown Einstein cross identified in this field.
Time Variability of Nonthermal X-Ray Stripes in Tycho’s Supernova Remnant with Chandra

Published: May 2020

Abstract
Analyzing Chandra data of Tycho's supernova remnant (SNR) taken in 2000, 2003, 2007, 2009, and 2015, we search for time-variable features of synchrotron X-rays in the southwestern part of the SNR, where stripe structures of hard X-ray emission were previously found. By comparing X-ray images obtained at each epoch, we discover a knot-like structure in the northernmost part of the stripe region became brighter particularly in 2015. We also find a bright filamentary structure gradually became fainter and narrower as it moves outward. Our spectral analysis reveals that not only the nonthermal X-ray flux but also the photon indices of the knot-like structure change from year to year. During the period from 2000 to 2015, the small knot shows a brightening of ∼70% and hardening of ΔΓ ∼ 0.45. The time variability can be explained if the magnetic field is amplified to

and/or if magnetic turbulence significantly changes with time.
Circular Polarization from Inhomogeneous Synchrotron Sources
Authors: Björnsson C.-I. 
Published: May 2020

Abstract
Inhomogeneities can influence the polarization emerging from a synchrotron source. However, it is shown that the frequency distribution of circular polarization is only marginally affected, although its magnitude may change substantially. This is used to argue that the observed properties of compact radio sources imply a radiating plasma in which the characteristic waves are nearly circular. As a result, restrictions can be put on the low-energy part of the energy distribution of the relativistic electrons as well as the presence of electron–positron pairs. It is emphasized that this constrains theoretical modeling of the acceleration process for the relativistic electrons; for example, some of the currently popular scenarios seem to need modifications to become consistent with observations.
The Impact of Type Ia Supernovae in Quiescent Galaxies. I. Formation of the Multiphase Interstellar Medium
Authors: Li 李 Miao 邈 , Li 黎 Yuan 原 , Bryan Greg L. , Ostriker Eve C. , Quataert Eliot 
Published: May 2020

Abstract
A cool phase of the interstellar medium has been observed in many giant elliptical galaxies, but its origin remains unclear. We propose that uneven heating from Type Ia supernovae (SNe Ia), together with radiative cooling, can lead to the formation of the cool phase. The basic idea is that since SNe Ia explode randomly, gas parcels that are not directly heated by SN shocks will cool, forming multiphase gas. We run a series of idealized high-resolution numerical simulations and find that cool gas develops even when the overall SN heating rate H exceeds the cooling rate C by a factor as large as 1.4. We also find that the time for multiphase gas development depends on the gas temperature. When the medium has a temperature T = 3 × 106 K, the cool phase forms within one cooling time

; however, the cool phase formation is delayed to a few times

for higher temperatures. The main reason for the delay is turbulent mixing. Cool gas formed this way would naturally have a metallicity lower than that of the hot medium. For constant H/C, there is more turbulent mixing for higher-temperature gas. We note that this mechanism of producing cool gas cannot be captured in cosmological simulations, which usually fail to resolve individual SN remnants.
L’expert au sein des organisations : définition et cadrage théorique
Authors: Bootz Jean-Philippe , Lièvre Pascal , Schenk Eric 
Published: May 2020

Les experts constituent depuis quelques années une figure de plus en plus incontournable au sein des organisations. En particulier, l’avènement de l’économie fondée sur les connaissances a propulsé cet acteur au centre des préoccupations dans la mesure où il joue un rôle clé dans les processus d’innovation. Les processus visant le développement et la valorisation des experts tendent ainsi à se multiplier. Si les démarches menées dans ce sens sont louables, elles souffrent fréquemment d’un déficit d’analyse et de compréhension des composants fondamentaux de l’expertise. En effet la qualification d’expert est souvent en pratique associée au nombre d’années d’expériences ou envisagée uniquement en lien avec des compétences techniques, de sorte qu’une confusion généralisée apparait entre expert et expérience et entre expert et spécialiste, ce qui pose des problèmes managériaux. Dans ce cadre, notre contribution vise à proposer un modèle définitionnel de l’expert au sein des organisations. La lecture des approches de l’expert en psychologie, en knowledge management ou en sociologie nous conduit à caractériser l’expert par une dimension à la fois cognitive et sociale qui sont ici regroupées au sein d’un cadre unique. L’expert est ainsi appréhendé comme un individu qui dispose d’une compétence à analyser et résoudre des situations diverses et non triviales en s’appuyant sur une capacité à combiner et à mobiliser rapidement connaissances scientifiques et expérientielles. Il dispose, par ailleurs, d’une légitimité sociale qui repose soit sur des signaux forts (appartenance à une structure formelle institutionnelle) soit sur des signaux faibles (au sein de réseaux informels auto-organisés).
Le spectre de la dépendance aux médicaments chez les usagers. Sens et enjeux d’une notion
Authors: Fainzang Sylvie 
Published: May 2020

Dans le contexte des scandales sanitaires liés aux médicaments et de la nécessité d'une pharmacovigilance, la question se pose des décisions que les individus prennent face aux prescriptions qui leur sont délivrées. Compte tenu des risques, réels ou non, associés à la prise de médicaments, les patients tendent de plus en plus à évaluer leurs prescriptions et à les aménager. Parmi ces risques figure la dépendance, dont la crainte incite souvent les usagers à refuser ou à modifier leurs prescriptions. Mais de quoi les usagers parlent-ils lorsqu’ils parlent de dépendance dans le champ médicamenteux ? On tentera ici de cerner les diverses acceptions de cette notion pour les sujets, afin d’éclairer les stratégies (modifications, réduction, sélection, adaptations) qu’ils adoptent pour limiter le risque de dépendance. On verra que, bien au-delà de la définition que lui donne la pharmacologie, c’est une relation existentielle et politique à la substance qui est redoutée, et qu’elle ne saurait être comprise sans être rapportée au développement contemporain de la notion d’autonomie.
LA CONVERSIONE DI ENERGIA SOLARE IN ENERGIA CHIMICA
Authors: Selli Elena 
Published: May 2020

Energy is the most important issue of the 21st century. Due to severe environmental problems, mainly related to air pollution of urban areas and green house effects leading to global warming, fossil fuels need to be replaced by renewable energy sources. Beside the wind energy, which is progressively more and more exploited, solar energy represents a clean, abundant, diffuse and economical energy which can be converted into heat, electricity or in the form of so called solar fuels, provided special materials are developed able to efficiently absorb solar light and produce charge separation. This is the prerequisite for obtaining electricity from sunlight and solar fuels, e.g. hydrogen from water photosplitting or carbon containing species from carbon dioxide photoinduced reduction, which can be stored and used on need. Converting solar energy into chemical energy is thus a big challenge for chemistry.

Summarizing the state of the terrestrial biosphere in few dimensions
Authors: Kraemer Guido , Camps-Valls Gustau , Reichstein Markus , Mahecha Miguel D. 
Published: May 2020

Abstract. In times of global change, we must closely monitor the state of the planet in
order to understand the full complexity of these changes. In fact, each of the
Earth's subsystems – i.e., the biosphere, atmosphere, hydrosphere, and
cryosphere – can be analyzed from a multitude of data streams.
However, since it is very hard to jointly interpret multiple monitoring data
streams in parallel, one often aims for some summarizing indicator. Climate
indices, for example, summarize the state of atmospheric circulation in a
region.
Although such approaches are also used in other fields of science, they are
rarely used to describe land surface dynamics.
Here, we propose a robust method to create global indicators for the terrestrial
biosphere using principal component analysis based on a high-dimensional set
of relevant global data streams.
The concept was tested using 12 explanatory variables representing the
biophysical state of ecosystems and land–atmosphere fluxes of water, energy, and carbon
fluxes. We find that three indicators account for 82 % of the variance of the
selected biosphere variables in space and time across the globe. While the
first indicator summarizes productivity patterns, the second indicator
summarizes variables representing water and energy availability. The third
indicator represents mostly changes in surface albedo. Anomalies in the
indicators clearly identify extreme events, such as the Amazon droughts (2005
and 2010) and the Russian heat wave (2010). The anomalies also allow us to
interpret the impacts of these events. The indicators can also be used to
detect and quantify changes in seasonal dynamics. Here we report, for instance,
increasing seasonal amplitudes of productivity in agricultural areas and
arctic regions. We assume that this generic approach has great potential for
the analysis of land surface dynamics from observational or model data.
Modeling of E. coli distribution for hazard assessment of bathing waters affected by combined sewer overflows
Authors: Locatelli Luca , Russo Beniamino , Acero Oliete Alejandro , Sánchez Catalán Juan Carlos , Martínez-Gomariz Eduardo , Martínez Montse 
Published: May 2020

Abstract. Combined sewer overflows (CSOs) affect bathing water
quality of receiving water bodies by bacterial pollution. The aim of this
study is to assess the health hazard of bathing waters affected by CSOs.
This is useful for bathing water managers, for risk assessment purposes, and
for further impact and economic assessments. Pollutant hazard was
evaluated based on two novel indicators proposed in this study: the mean
duration of insufficient bathing water quality (1) over a period of time
(i.e., several years) and (2) after single CSO/rain events. In particular, a
novel correlation between the duration of seawater pollution and the event
rainfall volume was developed. Pollutant hazard was assessed through a coupled urban drainage and seawater quality model that was
developed, calibrated and validated based on local observations.
Furthermore, hazard assessment was based on a novel statistical analysis of
continuous simulations over a 9-year period using the coupled model.
Finally, a validation of the estimated hazard is also shown. The health
hazard was evaluated for the case study of Badalona (Spain) even though the
methodology presented can be considered generally applicable to other urban
areas and related receiving bathing water bodies. The case study presented
is part of the EU-funded H2020 project BINGO (Bringing INnovation to OnGOing
water management – a better future under climate change).
A model for French-press experiments of dry snow compaction
Authors: Meyer Colin R. , Keegan Kaitlin M. , Baker Ian , Hawley Robert L. 
Published: May 2020

Abstract. Snow densification stores water in alpine regions and transforms snow into ice on the surface of glaciers. Despite its importance in determining snow-water equivalent and glacier-induced sea level rise, we still lack a complete understanding of the physical mechanisms underlying snow compaction. In essence, compaction is a rheological process, where the rheology evolves with depth due to variation in temperature, pressure, humidity, and meltwater. The rheology of snow compaction can be determined in a few ways, for example, through empirical investigations (e.g., Herron and Langway, 1980), by microstructural considerations (e.g., Alley, 1987), or by measuring the rheology directly, which is the approach we take here. Using a French-press or cafetière-à-piston compression stage, Wang and Baker (2013) compressed numerous snow samples of different densities. Here we derive a mixture theory for compaction and airflow through the porous snow to compare against these experimental data. We find that a plastic compaction law explains experimental results. Taking standard forms for the permeability and effective pressure as functions of the porosity, we show that this compaction mode persists for a range of densities and overburden loads. These findings suggest that measuring compaction in the lab is a promising direction for determining the rheology of snow through its many stages of densification.
