Sampah menjadi masalah utama diseluruh Kota di Indonesia. Kota Bekasi termasuk penyandang masalah sampah urutan ke 6 diseluruh Kota di Indonesia. Wali Kota Bekasi telah mencanangkan gerakan pengolahan sampah untuk mencari solusi permasalahan sampah di Kota Bekasi. Rukun Warga (RW) 26 adalah tempat yang dipilih TIM pengabdian pada Masyarakat Universitas Budi Luhur. Tim akan mengadakan pengabdian dalam memberikan solusi pemecahan masalah sampah yaitu dengan memberikan penyuluhan dan pelatihan pengolahan sampah kering dalam hal ini pengolahan sampah kantong kresek menjadi hiasan yang bermanfaat seperti bros, bunga dan hiasan dinding. Metode yang digunakan adalah metode observasi saat mencari lokasi yang akan dipilih untuk dijadikan tempat pengabdian. dan menggunakan metode wawancara dengan informan ketua RW 26, dan akhirnya diputuskan untuk memberikan pelatihan pengolahan sampah kering, karena pengolahan sampah basah sudah pernah didapat warga RW 26 dari dinas kota Bekasi. Hasil pengabdian kepada masyarakat menjelaskan 4 hasil sebagai berikut: 1. bahwa dari data kader PKK RW 26 berjumlah 83 orang. yang menghadiri kegiatan pelatihan sebanyak 49 orang Kader PKK dan petugas RT dan RW juga menghadirinya sebanyak 12 orang. Jadi total peserta lebih kurang 61 orang peserta pelatihan.2. Pelatihan yang diberikan ada 2 jenis pelatihan yaitu 1). Pelatihan membuat bunga dari kantong plastik. 2). Pelatihan membuat gantungan kunci dari plastik bungkus kopi.3. Berdasarkan pengukuran pengetahuan masyarakat peserta pelatihan. yang diukur adalah pengetahuan dalam pemilahan sampah antara sampah organik dan an organik serta sampah berbahaya terdapat bahwa 40% kader PKK masih ragu menentukankan antara sampah organik dan sampah anorganik. tetapi sudah mampu menjelaskan sampah berbahaya. 4. Pelatihan yang berhasil dan mampu dilaksanakan adalah bunga dari plastik dan gantungan kunci serta bros sebagai hiasan.

Este artigo tem por objetivo delinear um movimento intencionalmente insubordinado e criativo em defesa das potencialidades da Resolução CNE/CP n.o 02/2015 diante das desconstruções e dos descaminhos sinalizados pela Resolução CNE/CP n.o 02/2019. Para isso, apoia-se em uma abordagem qualitativa, associada à pesquisa documental. Como procedimento de coleta, compartilhamos o corpus que reuniu 172 Projetos Pedagógicos de Cursos (PPC) de Licenciatura em Matemática (LM) do país, dos quais 60 são ofertados por Universidades Federais, 44 por Universidades Estaduais e 68 por Institutos Federais de Educação, Ciência e Tecnologia. Para a análise, utiliza-se o paradigma indiciário de Carlo Ginzburg. Entre os resultados, a atenção ao percurso formativo delineado pelos PPC, a articulação entre formação inicial e continuada em diferentes espaços formativos, as discussões a respeito dos movimentos de constituição da Identidade Profissional e a defesa da indissociabilidade da tríade Ensino-Pesquisa-Extensão foram demarcadas como ações insubordinadas de resistência diante da implementação da Resolução CNE/CP n.o 02/2019. Esses elementos problematizadores nos deram indícios de que há possibilidades de elaboração de designs formativos insubordinados que contemplem ações associadas aos conhecimentos de que futuros professores de Matemática necessitam para ensinar, fazendo-se atravessados pela reflexão crítica e pelo compromisso com a democracia, a justiça social, a ética e a solidariedade.

Estimation of Stellar Atmospheric Parameters with Light Gradient Boosting Machine Algorithm and Principal Component Analysis

Published: March 2022

Abstract
In this paper, we propose a new method to estimate stellar atmospheric parameters with photometric data, which is based on principal component analysis (PCA) and light gradient boosting machine (LightGBM) algorithms. We first use PCA to transform all band photometric data (u, v, g, r, i, and z) and then utilize LightGBM to estimate stellar atmospheric parameters. The experimental results show that the root mean square errors of the method for estimating the effective temperature, surface gravity, and metallicity are 90 K, 0.40 dex, and 0.20 dex, respectively. We then compare PCA + LightGBM with the original photometry data (OPD) + LightGBM and the color index data (CID) + LightGBM. The experimental results show that the performance of PCA + LightGBM is better than that of CID + LightGBM and OPD + LightGBM, and PCA + LightGBM can solve the problems of model instability and inaccurate estimation results caused by direct use of OPD or CID as input for LightGBM. We believe the new features obtained by PCA can be used on photometric data collected by the Chinese Space Station Telescope.
Diagnosing the Circumburst Environment with Multiband Gamma-Ray Burst Radio Afterglows

Published: March 2022

Abstract
It has been widely recognized that gamma-ray burst (GRB) afterglows arise from interactions between the GRB outflow and circumburst medium, while their evolution follows the behaviors of relativistic shock waves. Assuming the distribution of circumburst medium follows a general power-law form, that is, n = A
*
R
−k
, where R denotes the distance from the burst, it is obvious that the value of the density-distribution index k can affect the behaviors of the afterglow. In this paper, we analyze the temporal and spectral behaviors of GRB radio afterglows with arbitrary k values. In the radio band, a standard GRB afterglow produced by a forward shock exhibits a late-time flux peak, and the relative peak fluxes, as well as peak times at different frequencies, show dependencies on k. Thus, with multiband radio-peak observations, one can determine the density profile of the circumburst medium by comparing the relations between peak flux/time and frequency at each observing band. Also, the effects of transrelativistic shock waves, as well as jets in afterglows, are discussed. By analyzing 31 long and 1 short GRB with multiband data of radio afterglows, we find that nearly half of them can be explained with a uniform interstellar medium (k = 0), ∼1/5 can be constrained to exhibiting a stellar-wind environment (k = 2), while less than ∼1/3 of the samples show 0 < k < 2.

Abstract
We present time-series photometry of 21 nearby type II Cepheids in the near-infrared J, H, and K

s
passbands. We use this photometry, together with the Third Gaia Early Data Release parallaxes, to determine for the first time period–luminosity relations (PLRs) for type II Cepheids from field representatives of these old pulsating stars in the near-infrared regime. We found PLRs to be very narrow for BL Herculis stars, which makes them candidates for precision distance indicators. We then use archival photometry and the most accurate distance obtained from eclipsing binaries to recalibrate PLRs for type II Cepheids in the Large Magellanic Cloud (LMC). Slopes of our PLRs in the Milky Way and in the LMC differ by slightly more than 2σ and are in a good agreement with previous studies of the LMC, Galactic bulge, and Galactic globular cluster type II Cepheids samples. We use PLRs of Milky Way type II Cepheids to measure the distance to the LMC, and we obtain a distance modulus of 18.540 ± 0.026(stat.) ± 0.034(syst.) mag in the W

JK
Wesenheit index. We also investigate the metallicity effect within our Milky Way sample, and we find a rather significant value of about −0.2 mag dex−1 in each band meaning that more metal-rich type II Cepheids are intrinsically brighter than their more metal-poor counterparts, in agreement with the value obtained from type II Cepheids in Galactic globular clusters. The main source of systematic error on our Milky Way PLRs calibration, and the LMC distance, is the current uncertainty of the Gaia parallax zero-point.
Orbit Tomography of Binary Supermassive Black Holes with Very Long Baseline Interferometry
Authors: Fang Yun , Yang Huan 
Published: March 2022

Abstract
In this work, we study how to infer the orbit of a supermassive black hole binary (SMBHB) by time-dependent measurements with very long baseline interferometry, such as the Event Horizon Telescope (EHT). Assuming a pointlike luminosity image model, we show that with multiple years of observations by EHT, it is possible to recover the SMBHB orbital parameters—eccentricity, (rescaled) semimajor axis, orbital frequency, and orbital angles—from their time-varying visibilities even if the binaries’ orbital periods are a few times longer than the duration of observation. Together with the future gravitational wave detections of resolved sources of SMBHBs with the pulsar timing array, and/or the detections of optical-band light curves, we will be able to further measure the individual mass of the binary, and also determine the Hubble constant if the total mass of the binary is measured through the light curves of the two black holes or measured by alternative methods.

Published: March 2022

Abstract
We use a generic formalism designed to search for relations in high-dimensional spaces to determine if the total mass of a subhalo can be predicted from other internal properties such as velocity dispersion, radius, or star formation rate. We train neural networks using data from the Cosmology and Astrophysics with MachinE Learning Simulations project and show that the model can predict the total mass of a subhalo with high accuracy: more than 99% of the subhalos have a predicted mass within 0.2 dex of their true value. The networks exhibit surprising extrapolation properties, being able to accurately predict the total mass of any type of subhalo containing any kind of galaxy at any redshift from simulations with different cosmologies, astrophysics models, subgrid physics, volumes, and resolutions, indicating that the network may have found a universal relation. We then use different methods to find equations that approximate the relation found by the networks and derive new analytic expressions that predict the total mass of a subhalo from its radius, velocity dispersion, and maximum circular velocity. We show that in some regimes, the analytic expressions are more accurate than the neural networks. The relation found by the neural network and approximated by the analytic equation bear similarities to the virial theorem.
Eruption of the EUV Hot Channel from the Solar Limb and Associated Moving Type IV Radio Burst

Published: March 2022

Abstract
Using the observations from the Solar Dynamics Observatory, we study an eruption of a hot-channel flux rope (FR) near the solar limb on 2015 February 9. The pre-eruptive structure is visible mainly in EUV 131 Å images, with two highly sheared loop structures. They undergo a slow rising motion and then reconnect to form an eruptive hot channel, as in the tether-cutting reconnection model. The J-shaped flare ribbons trace the footpoint of the FR that is identified as the hot channel. Initially, the hot channel is observed to rise slowly at 40 km s−1, followed by an exponential rise from 22:55 UT at a coronal height of 87 ± 2 Mm. Following the onset of the eruption at 23:00 UT, the flare reconnection then adds to the acceleration process of the coronal mass ejection (CME) within 3 R
⊙. Later on, the CME continues to accelerate at 8 m s−2 during its propagation period. Further, the eruption also launched type II radio bursts, which were followed by type III and type IVm radio bursts. The start and end times of the type IVm burst correspond to the CME’s core height of 1.5 and 6.1 R
⊙, respectively. Also, the spectral index is negative, suggesting that nonthermal electrons are trapped in the closed loop structure. Accompanied by this type IVm burst, this event is unique in the sense that the flare ribbons are very clearly observed together with the erupting hot channel, which strongly suggests that the hooked parts of the J-shaped flare ribbons outline the boundary of the erupting FR.

Abstract
Observations of present-day mass-loss rates for close-in transiting exoplanets provide a crucial check on models of planetary evolution. One common approach is to model the planetary absorption signal during the transit in lines like He i 10830 with an isothermal Parker wind, but this leads to a degeneracy between the assumed outflow temperature T

. In this study, we re-examine the isothermal Parker wind model using an energy-limited framework. We show that in cases where photoionization is the only heat source, there is a physical upper limit to the efficiency parameter ε corresponding to the maximal amount of heating. This allows us to rule out a subset of winds with high temperatures and large mass-loss rates as they do not generate enough heat to remain self-consistent. To demonstrate the utility of this framework, we consider spectrally unresolved metastable helium observations of HAT-P-11b, WASP-69b, and HAT-P-18b. For the former two planets, we find that only relatively weak (

Our results are in good agreement with more detailed self-consistent simulations and constraints from high-resolution transit spectra.
« Pertes et profils » : éditions « bleues » rouennaises du XVIII e siècle et collections conservées
Authors: Mellot Jean-Dominique 
Published: March 2022

Pour tenter de reconstituer le corpus et le volume de la Bibliothèque bleue rouennaise du xviii e siècle, la recherche mobilise les différentes sources d’archives à notre disposition. Est particulièrement exploité l’inventaire après décès de l’imprimeur-libraire Jean-François Behourt. Ce document recense pas moins de 533 953 exemplaires se rattachant à 188 titres (dont 119 pourvus d’un stock de plus de 1 000 exemplaires). Il dessine, en le rapprochant des inventaires troyens, un profil type de l’éditeur « bleu » du xviii e siècle, détenteur de presses, de titres et de stocks en quantités comparables d’un lieu à l’autre, et misant à 40 % au moins sur un répertoire religieux. Face à ce constat fondé sur les inventaires, le bilan de la conservation est bien maigre : 11 titres publiés par J.-F. Behourt ont été retrouvés sur les 40 titres les plus massivement représentés dans son inventaire — leçon de prudence dans l’approche de ce que fut la Bibliothèque bleue au dernier siècle de l’Ancien Régime.
Créer une dépendance républicaine à un « sentier trumpien » : la stratégie de Trump World pour les élections de 2022
Authors: Chervaux Maxime 
Published: March 2022

En 2016, Donald Trump a gagné la Maison Blanche grâce à l’appui de dernière minute des groupes et donateurs républicains ralliés à sa candidature. Après sa défaite en 2020, l’ancien président et ses alliés ont progressivement mis en place une structure de groupes para-républicains qu’ils cherchent à substituer aux groupes républicains traditionnels, notamment grâce à sa force de frappe financière. Armé de Trump World, il s’investit dans les élections de mi-mandat de 2022 pour effacer toute trace d’opposition en soutenant « ses » candidats et en défaisant ceux qui refusent d’adopter l’agenda « America First ». La stratégie est payante : peu de républicains osent critiquer l’ancien président, ou voter « contre lui » au Congrès. Il utilise par ailleurs ces élections pour rendre sa candidature inévitable en 2024, créant un « sentier trumpien » qui s’impose de plus en plus à tous les candidats conservateurs. Mais, ce faisant, Trump World propulse des candidats aux idées et aux histoires personnelles douteuses, ce qui pourrait les disqualifier aux yeux des modérés et des indépendants à l’automne, une fois les primaires gagnées, offrant ainsi quelques espoirs aux démocrates dans un contexte qui leur est peu favorable.
Épreuves biographiques et mises en œuvre de soi. Quelques enjeux de formation professionnelle dans l’éducation plurilingue
Authors: Molinié Muriel 
Published: March 2022

Le travail de création autobiographique peut-il nourrir des dynamiques de changement dans le champ social et professionnel du plurilinguisme/pluriculturalisme français ? L’article répond positivement à cette question, à condition d’œuvrer à l’articulation entre dispositifs (de recherche, de création, de professionnalisation), dans le cadre d’une discipline (ici, la didactique des langues, des cultures et du plurilinguisme) qui contribue à faire société à partir de notions centrales telles que la diversité, l’altérité et la mixité. Engagés dans une biographisation à la fois sociale et esthétique de l’expérience, les acteurs de l’éducation plurilingue et interculturelle sont alors plus armés pour se professionnaliser tout en analysant les contradictions qui caractérisent les épreuves de l’altérité vécues dans les institutions (éducatives, formatives, scientifiques) qu’ils contribuent ainsi à faire évoluer.

Entre devoir de réserve et liberté d’expression, un équilibre précaire pour les enseignants
Authors: Lemmens Éric , Demeuse Rodrigue 
Published: March 2022

Le droit à la liberté d’expression, s’il est fondamental dans une société démocratique, n’est cependant pas absolu. Les agents de la fonction publique, parmi lesquels se trouvent les enseignants, sont particulièrement susceptibles de subir des ingérences dans l’exercice de ce droit, en raison des devoirs et responsabilités particuliers qui pèsent sur leurs épaules. Dans la décision Mahi c. Belgique du 3 septembre 2020, la Cour européenne des droits de l’homme réaffirme ces principes avec force, tout en rappelant les balises qui doivent nécessairement encadrer de telles restrictions.
