The intermittent behaviour of renewable energy generation has become an essential issue for power deficiency in the distribution network. The high penetration of wind and solar became the primary task for the optimal size of energy storage to support the power mismatch. In the present work, the impact of the energy storage device with distribution generation (DGs) have been determined in a renewable integrated distribution system for power loss minimization. The main contribution of this paper is: (i) optimal location of DGs and battery are obtained by solving single and multi-objective functions. (ii) Determination of DG and battery size for minimization of power loss and system cost. (iii) Impact of battery energy storage device on loss profile and total cost of the system. The impact of day load variation has been considered in the study. The results have been obtained for IEEE-33 bus test system using a hybrid GAMS and particle swarm optimization (PSO) algorithm. The power loss is reduced to 47.60% with single DG and battery energy storage (BES). In addition, the power loss is reduced to 59.285% with two DGs and BES. The simulation results of the test system have been compared with other existing results.

Cloud computing offers streamlined instruments for outstanding business efficiency processes. Cloud distributors typically give two distinct forms of usage plans: Reserved as well as On-demand. Restricted policies provide inexpensive long-term contracting services, while order contracts were very expensive and ready for brief rather than long longer periods. In order to satisfy current customer demands with equal rates, cloud resources must be delivered wisely. Many current works depend mainly on low-cost resource-reserved strategies, which may be under-provisioning and over-provisioning rather than costly ondemand solutions. Since unfairness can cause enormous high availability costs and cloud demand variability in the distribution of cloud resources, resource allocation has become an extremely challenging issue. The hybrid approach to allocating cloud services according to complex customer orders is suggested in that article. The strategy was constructed as a two-step mechanism consisting of accommodation stages and then a versatile structure. In this way, by constructing each step primarily as an optimization problem, we minimize the total cost of implementation, thereby preserving service quality. By modeling client prerequisites as probability distributions are disseminated owing to the dubious presence of cloud requests, we set up a stochastic Optimization-based approach. Using various approaches, our technique is applied, and the results demonstrate its effectiveness when assigning individual cloud resources

This study is purposed to improve students' critical thinking skills. It is based on the reality of social life in the college or school environment, family, community, it can be seen that the low level of sensitivity, willingness, and ability of students to take part in solving various conflict problems. In daily life, students have generated attitudes and behaviors that are selforiented and become less sensitive to their social environment. In understanding conflict, the critical learning model is needed. Researchers are interested in conducting a research entitled Conflict-Based Learning Models to Improve Student's Critical Thinking Skills at the Faculty of Sharia, Imam Bonjol State Islamic University, Padang. The development of this conflictbased learning model is necessary to do because there has been no conflict-based learning model with a socio-cultural perspective to resolve agrarian conflicts recently. It is hoped that by using this model, students in analyzing and resolving agrarian conflicts will not only use legalistic-positivistic state legal instruments but also approach the rules found in local communities, so there are no prolonged conflicts anymore. This type of research is development research or what is called Research and Development (R&D) with qualitative and quantitative approaches. The Conflict-based Learning Model in order to Improve Students 'Thinking Ability in this study has produced a valid, practical, and effective model because it has an impact on increasing students' critical thinking skills and learning motivation.

Salah satu masalah saat ini di dunia adalah pademi covid-19. Tak terkecuali di Indonesia yang ikut terkena dampak dari virus tersebut baik secara sosial, yaitu kita diharuskan menerapkan sosial distancing. Maupun secara ekonomi, yang berdampak terhadap sebagian kalangan UMKM maupun perusahaan besar. Menurut data pada tanggal 11 September 2020 di pemerintah setempat Kecamatan Banjaran, Kabupaten Bandung, Jawa Barat terdapat tiga orang dinyatakan positif, dan tiga orang suspek. Hal ini sangat menghawatirkan, mengingat salah satu ruangan yang tepat dimasuki banyak orang adalah angkutan umum, ketika fase new normal diberlakukan, angkutan kota di Banjaran masih dipenuhi oleh lalu-lalang masyarakat tanpa protokol kesehatan yang ketat karena kurangnya sosialisasi dan pengawasan angkutan kota di daerah tersebut ehingga perlu adanya sistem otomatis yang dapat memudahkan pengendara dalam mengontrol jumlah penumpang pada transportasi umum. Sistem tersebut dibuat dengan menggunakan bantuan  sensor  ultrasonic dan buzzer. Buzzer ini akan berbunyi seperti alarm jika jumlah penumpang dalam angkutan umum melebihi kapasitas yang telah ditentukan. Harapannya, dengan adanya alat tersebut dapat menjadi solusi yang efektif untuk menekan penyebaran covid-19 terutama di angkutan umum.

During the staphylococcal infection, changes in the interaction of glandular cells, dystrophic and disorganizing pathologies in tissues, especially acute structural and hemodynamic changes in the stroma of the glands in the pituitary-adrenal-thyroid system, develop from the first day of the experiment. At the end of the experiment, on the background of a decrease in exudative processes, fibroplastic reactions are significantly activated, resulting in signs of incomplete regeneration – mainly sclerotic processes and cystic-atrophic changes in the parenchyma. Structural changes in tissues in the early stages of staphylococcal infection and the dynamics of development are characterized by specific symptoms in each of the glands. Since the pituitary gland is exposed to endogenous and exogenous factors earlier and more often than the adrenal glands, and the adrenal glands are earlier than the thyroid gland, dystrophic and destructive changes in the pituitary and adrenal glands are more pronounced at the early stage of the experiment. These morphological changes can change the hormonal status of the body and lead to dysfunction of the endocrine system as a whole – a decrease in the functional activity of the glands to some extent, and even inhibition of adenohypophyseal cells. Key words: staphylococcal infection, peritonitis, pituitary, adrenal and thyroid glands

Voting is the defining act for a democracy. However, voting is only meaningful if public deliberation is grounded in veritable and equitable information. This essay investigates the politicization of public health practices during the Democratic primaries in the context of the 2020 U.S. presidential election, using a dataset of more than 67 million tweets. We find the public sphere on Twitter is politically heterogeneous and the majority—liberal and conservative alike—advocates for wearing masks and vote-by-mail. However, a small, but dense group of conservative users push anti-mask and voter fraud narratives.

Background: Neurotherapy is an alternative and complementary medicine originated in India. It is drugless holistic treatment founded and developed by Sh. Lajpatrai Mehra respectfully called “Guruji” by using ancient knowledge of ‘Nadi Vigyan’ (knowledge of nervous system), Ayureveda and principles of Anatomy and Physiology.

Summary: t uses the finding of medical physiology but views them from a uniquely and refreshing approach, one that negates the use of medicines or drugs. Supported by basis of physiology, Dr. Lajpatrai Mehra (Guruji) has combined these palpations with symptoms and related them with various health conditions.

Key message: The therapy acts on root-cause of the disease. It uncovers the root cause of the disease and cures the same in a sophisticated manner without the use of drugs or medication. It is simple therapy with potential to normalize or revive the functioning of the organs
WIYN Open Cluster Study. LXXXV. Li in NGC 2243: Implications for Stellar and Galactic Evolution
Authors: Anthony-Twarog Barbara J. , Deliyannis Constantine P. , Twarog Bruce A.
Published: March 2021

High-dispersion spectra in the Li λ6708 region have been obtained and analyzed in the old, metal-deficient cluster NGC 2243. From Hydra spectra for 29 astrometric and radial velocity members, we derive rotational velocities, as well as [Fe/H], [Ca/H], [Si/H], and [Ni/H] based on 17, 1, 1, and 3 lines, respectively. Using ROBOSPECT, an automatic equivalent width measurement program, we derive [Fe/H] = −0.54 ± 0.11 (MAD), for an internal precision for the cluster [Fe/H] below 0.03 dex. Given the more restricted line set, comparable values for [Ca/H], [Si/H], and [Ni/H] are −0.48 ± 0.19, −0.44 ± 0.11, and −0.61 ± 0.06, respectively. With E(B − V) = 0.055, appropriate isochrones imply (m − M) = 13.2 ± 0.1 and an age of 3.6 ± 0.2 Gyr. Using available VLT spectra and published Li abundances, we construct an Li sample of over 100 stars extending from the tip of the giant branch to 0.5 mag below the Li dip. The Li dip is well populated and, when combined with results for NGC 6819 and Hyades/Praesepe, implies a mass/metallicity slope of 0.4 M
⊙/dex for the high-mass edge of the Li dip. The A(Li) distribution among giants reflects the degree of Li variation among the turnoff stars above the Li dip, itself a function of stellar mass and metallicity and strongly anticorrelated with a v
rot distribution that dramatically narrows with age. Potential implications of these patterns for the interpretation of Li among dwarf and giant field populations, especially selection biases tied to age and metallicity, are discussed.
Natively Periodic Fast Multipole Method: Approximating the Optimal Green’s Function
Authors: Gnedin Nickolay Y.
Published: March 2021

The fast multipole method (FMM) obeys periodic boundary conditions “natively” if it uses a periodic Green’s function for computing the multipole expansion in the interaction zone of each FMM oct-tree node. One can define the “optimal” Green’s function for such a method that results in the numerical solution that converges to the equivalent particle-mesh (PM) solution in the limit of sufficiently high order of multipoles. A discrete functional equation for the optimal Green’s function can be derived, but is not practically useful as methods for its solution are not known. Instead, this paper presents an approximation for the optimal Green’s function that is accurate to better than 10−3 in

norm and 10−4 in L
2 norm for practically useful multipole counts. Such an approximately optimal Green’s function offers a practical way for implementing the FMM with periodic boundary conditions natively, without the need to compute lattice sums or to rely on hybrid FMM-PM approaches.
Living with Neighbors. III. The Origin of the Spin–Orbit Alignment of Galaxy Pairs: A Neighbor versus the Large-scale Structure
Authors: Moon Jun-Sung , An Sung-Ho , Yoon Suk-Jin
Published: March 2021

Recent observations revealed a coherence between the spin vector of a galaxy and the orbital motion of its neighbors. We refer to the phenomenon as “the spin–orbit alignment (SOA)” and explore its physical origin via the IllustrisTNG simulation. This is the first study to utilize a cosmological hydrodynamic simulation to investigate the SOA of galaxy pairs. In particular, we identify paired galaxies at z = 0 having the nearest neighbor with mass ratios from 1/10 to 10 and calculate the spin–orbit angle for each pair. Our results are as follows. (a) There exists a clear preference for prograde orientations (i.e., SOA) for galaxy pairs, qualitatively consistent with observations. (b) The SOA is significant for both baryonic and dark matter spins, being the strongest for gas and the weakest for dark matter. (c) The SOA is stronger for less massive targets and for targets having closer neighbors. (d) The SOA strengthens for galaxies in low-density regions, and the signal is dominated by central–satellite pairs in low-mass halos. (e) There is an explicit dependence of the SOA on the duration of interaction with its current neighbor. Taken together, we propose that the SOA witnessed at z = 0 has been developed mainly by interactions with a neighbor for an extended period of time, rather than tidal torque from the ambient large-scale structure.
Pre-eruption Splitting of the Double-decker Structure in a Solar Filament
Authors: Pan Hanya , Liu Rui , Gou Tingyu , Kliem Bernhard , Su Yingna , Chen Jun , Wang Yuming
Published: March 2021

Solar filaments often erupt partially. Although how they split remains elusive, the splitting process has the potential of revealing the filament structure and eruption mechanism. Here we investigate the pre-eruption splitting of an apparently single filament and its subsequent partial eruption on 2012 September 27. The evolution is characterized by three stages with distinct dynamics. During the quasi-static stage, the splitting proceeds gradually for about 1.5 hr, with the upper branch rising at a few kilometers per second and displaying swirling motions about its axis. During the precursor stage that lasts for about 10 minutes, the upper branch rises at tens of kilometers per second, with a pair of conjugated dimming regions starting to develop at its footpoints; with the swirling motions turning chaotic, the axis of the upper branch whips southward, which drives an arc-shaped extreme-ultraviolet front propagating in a similar direction. During the eruption stage, the upper branch erupts with the onset of a C3.7-class two-ribbon flare, while the lower branch remains stable. Judging from the well-separated footpoints of the upper branch from those of the lower one, we suggest that the pre-eruption filament processes a double-decker structure composed of two distinct flux bundles, whose formation is associated with gradual magnetic flux cancellations and converging photospheric flows around the polarity inversion line.
Eruptive Behavior of Magnetically Layered Protoplanetary Disks in Low-metallicity Environments
Authors: Kadam Kundan , Vorobyov Eduard , Kóspál Ágnes
Published: March 2021

A protoplanetary disk (PPD) typically forms a dead zone near its midplane at a distance of a few astronomical units from the central protostar. Accretion through such a magnetically layered disk can be intrinsically unstable and has been associated with episodic outbursts in young stellar objects. We present the first investigation into the effects of a low-metallicity environment on the structure of the dead zone, as well as the resulting outbursting behavior of the PPD. We conducted global numerical hydrodynamic simulations of PPD formation and evolution in the thin-disk limit. The consequences of metallicity were considered via its effects on the gas and dust opacity of the disk, the thickness of the magnetically active surface layer, and the temperature of the prestellar cloud core. We show that the metal-poor disks accumulate much more mass in the innermost regions as compared to the solar-metallicity counterparts. The duration of the outbursting phase also varies with metallicity; the low-metallicity disks showed more powerful luminosity eruptions with a shorter burst phase, which was confined mostly to the early, embedded stages of the disk evolution. The lowest-metallicity disks with the higher cloud core temperature showed the most significant differences. The occurrence of outbursts was relatively rare in the disks around low-mass stars, and this was especially true at the lowest metallicities. We conclude that the metal content of the disk environment can have profound effects on both the disk structure and evolution in terms of episodic accretion.

We present StrayCats, a catalog of NuSTAR stray light observations of X-ray sources. Stray light observations arise for sources 1°–4° away from the telescope pointing direction. At this off-axis angle, X-rays pass through a gap between the optics and aperture stop and so do not interact with the X-ray optics; instead, they directly illuminate the NuSTAR focal plane. We have systematically identified and examined over 1400 potential observations resulting in a catalog of 436 telescope fields and 78 stray light sources that have been identified. The sources identified include historically known persistently bright X-ray sources, X-ray binaries in outburst, pulsars, and type I X-ray bursters. In this paper, we present an overview of the catalog, how we identified the StrayCats sources, and the analysis techniques required to produce high-level science products. Finally, we present a few brief examples of the science quality of these unique data.
Les chemins de fer de Madagascar (1901-1936)
Authors: Fremigacci Jean
Published: March 2021

Résumé Durant le premier tiers du xx e siècle, un embryon de réseau ferré voit le jour à Madagascar, reliant les Hautes-Terres à la côte. Répondant à une volonté politique fondée sur les projections des colons et de l’administration, cette entreprise révèle, de sa conception à sa réalisation, une profonde indifférence à l’égard des logiques économiques et des impératifs techniques. Cette faillite s’accompagne en outre, de profondes répercussions sociales, dues au recours massif, quoique dissimulé, au travail forcé.
La variation des identités élitaires des Hauts fonctionnaires. Étude du rôle de l’enseignement supérieur en France, en Grande-Bretagne et en Norvège
Authors: Mangset Marte
Published: March 2021

Le degré d’identification des membres d’une profession à la notion d’élite est, selon John Scott (2008), lié à leur degré d’intégration et de cohésion et à leur capacité d’action collective. Si l’on définit l’élite comme l’ensemble de ceux qui occupent des positions au sommet d’institutions de pouvoir, les hauts responsables des ministères des Finances et de la Culture font clairement partie de l’élite. Se per­çoivent-ils, pour autant, comme tels ? Une analyse inductive de 81 entretiens avec des hauts fonctionnaires britanniques, français et norvégiens montre que les Britanniques et les Français se définissent comme une élite tout court, une « élite sociétale », alors que les Norvégiens se perçoivent comme une élite plus restreinte, une « élite sectorielle ». Comment comprendre cette variation entre identités élitaires au sein d’une même profession dans des contextes sociaux différents ? L’examen de deux dimensions clés dans la théorie des élites suggère qu’il importe de prendre en compte les caractéristiques des systèmes d’enseignement supérieur plus encore que la circulation entre positions d’élite au sein de différents secteurs. Nous plaidons, en conclusion, pour un dialogue accru de la sociologie des élites et de la stratification avec la sociologie de l’éducation.
Original Body Contour : Notes nouvelles sur Robert Quine, mercenaire intègre du rock
Authors: Picard Louis
Published: March 2021

Quel est le point commun entre Richard Hell, John Zorn, Lou Reed et Brian Eno ? Tous ont fait appel aux « guitaroïdes » services de Robert Quine, musicien admirable mais méconnu – s’inscrivant ainsi dans la cohorte des musiciens de studio à l’apport décisif et secret – quand il n’est pas mal aimé, faute de rentrer dans les cases du bon goût rock. Si bien que ce texte de Louis Picard est moins une discographie sélective ou un exercice de réhabilitation qu’une méditation sur l’éthique du jeu de guitare et les faces B de l’Histoire.
Contre la quantification du beau : treize raisons pour lesquelles je ne peux choisir mes treize disques préférés
Authors: Daniel Drew , Loncan Hervé
Published: March 2021

Pratique embarrassante du journalisme en ligne, contestable dans la forme comme dans le fond, les listicles (néologisme obtenu par la contraction des mots liste et article) sont le douloureux quotidien de l’amateur de musique du troisième millénaire. Attrape-clics, auto-promo, raccourcis problématiques… Ils condensent à eux seuls à peu près toutes les tares de la presse en ligne dédiée à la musique. En septembre 2014, dans les pages de The Quietus , Drew Daniel, moitié du duo électronique Matmos, professeur de littérature américaine et musicophage insatiable, retournait l’exercice, l’éventrait et en extirpait toutes les humeurs, pour mieux en exposer la profonde perversion.
Le monde d'échos d’Arthur Russell
Authors: Lawrence Tim , Loncan Hervé
Published: March 2021

« Dans la pop bubble gum , l’idée de son pur n’était pas une philosophie, mais bien une réalité. À cet égard, la bubble gum était en avance sur l’avant-garde. » Ces mots d’Arthur Russell, programmatiques, tirés d’un entretien mené par son collaborateur Peter Zummo, datent de 1977, soit près de dix ans avant la sortie de son album World of Echo . Le « son pur » aura été pour Russell la quête d’une vie, débutée dans son Iowa natal, poursuivie à San Francisco, puis au cœur du chaudron créatif et expérimental de Downtown Manhattan. À la croisée de plusieurs scènes, classique (ou néo-classique), minimaliste, new-wave ou disco, rendues poreuses par sa seule grâce, Russell fut un personnage discret mais essentiel, aussi bien pour le New York cérébral et expérimental de la Kitchen que pour celui, hédoniste et sensuel, de la Gallery de Nicky Siano. Si aujourd’hui, après sa « redécouverte » au début des années 2000, Arthur Russell est largement admiré des mélomanes, il n’a de son vivant jamais réellement connu ni succès ni reconnaissance, expérimentant sans répit, déterritorialisant genres et pratiques, multipliant les collaborations rhizomatiques (oui, encore), et tentant de trouver le passage vers une hypothétique troisième voie du son. Dans ce chapitre de Hold On to Your Dreams : Arthur Russell and the Downtown Music Scene , 1973 -1992, la biographie qu’il lui a consacrée en 2009, l’essayiste et universitaire londonien Tim Lawrence dépeint le contexte, les processus et l’état d’esprit qui ont mené à la concrétisation de World of Echo , œuvre unique pour voix et violoncelle, où les recherches sonores d’Arthur Russell, toujours en équilibre instable, en porte-à-faux, trouve peut-être leur plus somptueux aboutissement.
Italie’ 70 : musique légère, années de plomb
Authors: Lisarelli Diane
Published: March 2021

L’actualité éditoriale consacrée à l’autonomie italienne est riche, avec la publication des ouvrages de Nanni Balestrini, Alessandro Stella, ou plus récemment encore de la somme La Horde D’Or (Balestrini/Moroni). Diane Lisarelli, journaliste et auteure indépendante basée à Nice, qui a notamment signé Éternels retours , un texte consacré à Lucio Battisti pour la NRF , s’est intéressée à la place des concerts dans cette période politique agitée : le goût et le dégoût pour les groupes étrangers, le cynisme des festivals commerciaux et les ambivalences des événements alternatifs, l’affirmation de la pop comme art populaire en même temps que sa critique comme industrie et comme opium, les actions pour empêcher que soit donné un prix à la culture, l’expression musicale des tensions existentielles, la continuité de fait entre musique et luttes sociales… À rebours des évocations romantiques de la musica leggera et de la « contre-culture », elle nous propose un parcours des scansions et des matières d’une révolte. Abordés au ras des événements d’alors, ces thèmes correspondent d’abord à des manières d’agir sur le moment, parfois avec brutalité, obligeant chacun à choisir son camp.
Musique & Internet : vous ne devinerez jamais les impacts sur votre cerveau !
Authors: Harper Adam , Thomas Chloé
Published: March 2021

Après avoir déjà publié dans Audimat au sujet de l’underground des années 1980 et des affects sonores du Brexit, Adam Harper nous propose dans ce numéro un texte sur son thème préféré : la persistance des genres dans la musique électronique et ses résonances avec un air du temps plus général. Le point de départ de cet article ne cesse de résonner à longueur de tribunes : l’idée que les conditions de l’expérience de la musique et des médias seraient profondément modifiées par l’internet, et sans doute pour le pire. Si l’on veut bien écouter attentivement les exemples de cette esthétique musicale que l’on dit « digitale », on s’aperçoit que ses effets sont plus variés qu’il n’y paraît. Certes, par certains aspects, ils semblent refléter la sensibilité désordonnée et la surcharge cognitive qu’on attribue à l’internet. Mais ils sont aussi une exagération, une représentation et une mise en perspective de ces effets, qu’ils maîtrisent et distordent, qui nous encouragent à prendre du recul sur notre rapport à l’alerte, à l’immersion, à l’affect et à la pensée. Plutôt que de toujours lire dans la musique les conséquences des technologies médiatiques, semble nous dire Harper, on peut sonder ses aspérités pour en apprendre plus sur nos propres manières de fantasmer et d’hystériser l’époque.
Nouveaux rêves cyberpunk
Authors: Llewellyn Philippe
Published: March 2021

À la lecture du premier jet de ce texte enthousiaste et touffu qu’un inconnu et novice du nom de Philippe Llewellyn nous avait envoyés l’an dernier, nous avions regretté d’avoir trop vite méprisé la microscène vaporwave , née au début de notre décennie. Ne serait-ce que parce que ce mépris nous avait fait louper les horizons hardvapour et dreampunk suggérés au genre par le label Dream Catalogue, sujet principal de l’article. Au passage, Llewellyn évoquait avec passion l’esthétique cyberpunk – ses films fondateurs, leurs bandes originales, leurs villes rêvées ou réelles. Nous lui avons donc demandé de greffer à sa monographie quelques éléments d’une histoire de la musique cyberpunk. Loin de faire interférence, les images et les références qui accompagnent les sorties discographiques de Dream Catalogue lui donnent toute sa dignité, celle d’une bande-son d’imaginaires dont elle est absolument solidaire. Et loin de ne constituer qu’une série de codes rebattus, ces imaginaires fonctionnent comme une réactualisation toujours plus abstraite et mélancolique de ce que le cyberpunk a laissé flotter dans notre inconscient collectif. Au moment où Blade Runner et Ghost In The Shell font réapparaître sur nos écrans des réplicants et des simulacres au carré, les artistes affiliés au label recyclent un réseau de références plus dense qu’il n’y paraît. Ils y puisent des émotions toutes prêtes, certes, mais qui n’ont rien de naïves. Pour Llewellyn, les musiciens cyberpunk d’aujourd’hui, plutôt que d’imaginer un futur radicalement nouveau, choisissent de fouiller entre les mailles du futur et du passé, de la ville mondiale et de ses marges ghettoïsées, et s’ils traversent les clichés, c’est pour un jour mieux imaginer de nouvelles utopies.
Aimer le punk en féministe
Authors: Willis Ellen
Published: March 2021

Référence explicite du texte de Mark Fisher, Ellen Willis a été témoin de « l’atrophie de la conscience » qui a paradoxale- ment pris forme dans les années 1970 : car à mesure que les années 1960, à peine achevées, se voyaient exaltées comme un symbole de liberté, une bonne partie de la jeunesse se trouvait prise au piège d’un rabougrissement de ses conditions de vie et de l’affaiblissement des espoirs de transformation de la société. Le punk a alors exprimé ce sentiment de captivité, mais au premier abord, il reste une musique de machos violents. Que faire de cela quand on est féministe ? Ellen Willis, en reliant sa trajectoire d’auditrice à ses dilemmes existentiels, nous montre que la meilleure musique est souvent celle qui permet d’éprouver et de traverser les contradictions.
