The Imprint of Large-scale Structure on the Ultrahigh-energy Cosmic-Ray Sky
Authors: Ding 丁忱 Chen , Globus Noémie , Farrar Glennys R. 
Published: May 2021

Abstract
Ultrahigh-energy cosmic rays (UHECRs) are atomic nuclei from space with vastly higher energies than any other particles ever observed. Their origin and chemical composition remain a mystery. As we show here, the large and intermediate angular scale anisotropies observed by the Pierre Auger Observatory are a powerful tool for understanding the origin of UHECRs. Without specifying any particular production mechanism but only postulating that the source distribution follows the matter distribution of the local universe, a good accounting of the magnitude, direction, and energy dependence of the dipole anisotropy at energies above 8 × 1018 eV is obtained after taking into account the impact of energy losses during propagation (the “GZK horizon”), diffusion in the extragalactic magnetic field, and deflections in the Galactic magnetic field (GMF). This is a major step toward the long-standing hope of using UHECR anisotropies to constrain UHECR composition and magnetic fields. The observed dipole anisotropy is incompatible with a pure proton composition in this scenario. With a more accurate treatment of energy losses, it should be possible to further constrain the cosmic-ray composition and properties of the extragalactic magnetic field, self-consistently improve the GMF model, and potentially expose individual UHECR sources.

The presence of large peatland in Riau, Indonesia, could cause air pollution due to peatland fires which causes the presence of thick smoke every year in Riau, dis-rupting human activities. In order to monitor the air quality, in this paper, the main advantage of the Internet of Things (IoT) is the ability to transfer data over the network without requiring human-to-human or human interaction to the com-puter used. In this paper, we propose an air quality monitor that can display web-based information to show the temperature and air humidity, and detects CO, CO2 gases, and alcohol in real time with the help of DHT11 and MQ135 sensors, Arduino Uno and Raspberry Pie. The results show our proposed system can successfully show each parameter of the air quality on the website and make suggestions about the overall air quality level. With our proposed system, we hope the government can respond faster to mitigate the bad air quality level and give information to public about the air quality level in a faster and more accurate way.

<p class="0abstract">The extremely vibrant, scattered, and non–transparent nature of cloud computing formulate trust management a significant challenge. According to scholars the trust and security are the two issues that are in the topmost obstacles for adopting cloud computing. Also, SLA (Service Level Agreement) alone is not necessary to build trust between cloud because of vague and unpredictable clauses. Getting feedback from the consumers is the best way to know the trustworthiness of the cloud services, which will help them improve in the future. Several researchers have stated the necessity of building a robust management system and suggested many ideas to manage trust based on consumers' feedback. This paper has reviewed various reputation-based trust management systems, including trust management in cloud computing, peer-to-peer system, and Adhoc system. </p>

Published: May 2021

Purpose: To investigate the antioxidant and anti-inflammatory effects of aqueous leaf extract of T. laurifolia against alcoholic liver injury in rats.
Methods: Male Wistar rats were administered either normal saline, ethanol (EtOH), normal saline with low or high dose T. laurifolia leaf extract (TL-LD or TL-HD), EtOH with TL-LD or EtOH with TL-HD. Blood biochemical indices: hepatic malondialdehyde (MDA) levels, liver histopathology, hepatic cytochrome P450 2E1 (CYP2E1), nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, and pro-inflammatory cytokines, including interleukin 1 beta (IL-1β) and tumor necrotic factor alpha (TNF-α) mRNA expressions, were determined using standard methods.
Results: The leaf extract of T. Laurifolia decreased hepatic MDA levels, improved liver pathology and down-regulated mRNA expressions of CYP2E1, NADPH oxidase and pro-inflammatory cytokinesin ethanol-treated rats.
Conclusion: These results demonstrate that aqueous extract of T. Laurifolia exerts hepatoprotective effect against alcoholic liver injury through a mechanism involving inhibition of oxidative stress and inflammation.
Chromatographic determination of siphonodin content: A rapid and simple strategy for discriminating between Hemsleya omeiensis and other sources of Xuedan
Authors: Qin Yi , Zhang Hong-ling , Wang Jin , Huang Qin-wan , Sun Ji-lin , Yao Ren-chuan 
Published: May 2021

Purpose: To develop a rapid and simple siphonodin content-based high performance liquid chromatography (HPLC) method to distinguish Hemsleya omeiensis from other sources of xuedan.
Methods: Siphonodin was isolated from Hemsleya omeiensis and identified by x-ray crystallographic analysis. An optimized HPLC method was applied for the determination of siphonodin contents of H. omeiensis, H. dolichocarpa and H. gigantha.
Results: Siphonodin was successfully separated by the optimized HPLC method in < 10 min, and the results of validation showed that the HPLC method was stable and very accurate for the quantification of siphonodin. The mean content of siphonodin in 10 batches of H. omeiensis was 3.78 mg/g, but the compound was not detectable in H. dolichocarpa and H. gigantha using the developed HPLC method.
Conclusion: These results indicate that the developed HPLC method is suitable for distinguishing H. omeiensis from other sources of xuedan.
Cost associated with hospitalization of non-adherent type 2 diabetes patients in a tertiary healthcare facility in Ibadan, Nigeria
Authors: Ipingbemi Aduke Elizabeth , Erhun Wilson Oyekigho 
Published: May 2021

Purpose: To estimate the cost of hospitalization associated with medication non-adherence among type 2 diabetes mellitus (T2DM) patients in a tertiary healthcare facility in Nigeria.
Methods: Three hundred and fifty-four (354) medical records of T2DM patients admitted into the medical wards from 2013 to 2015 were used for the study. Medical records with history of medication non-adherence (MNA) prior to hospitalization as indicated by physicians were included in the study. Direct medical costs associated with the management of the patients during hospitalization were measured using out-of-pocket payer perspective. Pearson product moment correlation coefficient was used to determine the relationship between the variables, with p < 0.05 considered statistically significant.
Results: Among the 354 admitted patients, 226 (63.8 %) had a record of MNA. The mean age was 57.5years ± 14.6. The majority of the patients (61.5 %) were either petty traders or artisans/selfemployed. Duration of hospitalization increased with increase in number of comorbid disease (Pearson product moment correlation r = 0.13 p = 0.05). Total cost incurred during hospitalization was US$146,669.3 (average, $ 650.1), of which more than one quarter was cost of medications. Cost of management and cost of laboratory investigations increased with increase in the number of co-morbid diseases (r = 0.24, p = 0.00; r = 0.2, p = 0.02, respectively). Cost of management also increased with increase in days of hospitalization (r = 0.2, p = 0.00).
Conclusion: Cost of hospitalization related to non-adherence to medication is high among the studied population. There is need to work out strategies to enhance adherence among diabetes patients.
Implication of cholinergic transmission in rat model of spinal cord injury: A potential therapeutic target
Authors: Liu Hongzhe , Chang Lei , Peng Shuai , Liu Bin , Zhang Mingyan , Liu Xiangyang 
Published: May 2021

Purpose: To assess the involvement of cholinergic transmission in the etiology of spinal cord injury (SCI) in a rat model.
Methods: Male adult rats (Wistar) with body weight ranging from 200 to 250 g were equally allocated into 2 groups: test (SCI) and control (non-SCI). Clipping method was used to induce SCI. Thereafter, motor function was measured using rotarod. Each rat was sacrificed by decapitation, and the cortex was excised for use in the study of the involvement of cholinergic transmission in SCI using real time quantitative polymerase chain reaction (RT-PCR) and western blot analysis (WBA).
Results: Significant upregulation in acetylcholine esterase (AChE) was observed in the cortex of SCI rats, relative to non-SCI rats (p < 0.005). Results from cholinergic receptor binding studies revealed significantly decreased maximum binding (Bmax) and dissociation constant (kd) values for muscarinic receptors in SCI rats, when compared to non-SCI rats. Moreover, the reduction in intensity of cholinergic receptors was significantly greater in the cerebral cortex of SCI group compared to non-SCI group.
Conclusion: The results of this study suggested that the reduction in cortical cholinergic transmission impairs motor functions in SCI, and plays a major role in motor deficits in SCI.

Authors: Iwegbu Chuks Justus 
Published: May 2021

The paper, “Ameliorating the Rising Insecurity situation in Nigeria: Skills Development Initiative through Social Science Education as alasting Tool” has as its main thrust, the principle of using skills development initiative as a reliable too of engaging able bodied, healthy and willing men and women in order to get them out of the street in line with the popular aphorism “that an idle mind is the devils workshop “which indeed explains it all. To further appreciate this intellectual discuss, basic concepts relevant to the article such as Insecurity which is generally seen as the state of being open to danger or the uncertainty or anxiety about oneself safety is also examined. Importantly too, Skill Development Initiative is also in this discuss defined as the act of providing vocational training to people both young and old, students and even school dropouts, existing workers, and everyone interested in earning a living through practical skill etc. The concept of Social Science Education and other concepts in this discourse such as Skills, Development, Initiative and the phrase Skills Development Initiative were adequately defined etc. the paper concludes by asserting firmly that creating awareness, education and information through tactical deployment of Social Sciences Education classroom instructional process on the use of Skills Development Initiatives remains a functional and effective way of curbing the problem of dwindling insecurity problem in the Society today. Steps on how this can be effectively done through teaching and training were proffered.

Bialynicki-Birula schemes in higher dimensional Hilbert schemes of points and monic functors
Authors: Evain Laurent , Lederer Mathias 
Published: May 2021

The Bialynicki-Birula strata on the Hilbert scheme $H^n(\mathbb{A}^d)$ are smooth in dimension $d=2$. We prove that there is a schematic structure in higher dimensions, the Bialynicki-Birula scheme, which is natural in the sense that it represents a functor. Let $\rho_i:H^n(\mathbb{A}^d)\rightarrow {\rm Sym}^n(\mathbb{A}^1)$ be the Hilbert-Chow morphism of the ${i}^{th}$ coordinate. We prove that a Bialynicki-Birula scheme associated with an action of a torus $T$ is schematically included in the fiber $\rho_i^{-1}(0)$ if the ${i}^{th}$ weight of $T$ is non-positive. We prove that the monic functors parametrizing families of ideals with a prescribed initial ideal are representable.Comment: Final version
Combinatorial Reid's recipe for consistent dimer models
Authors: Craw Alastair , Heuberger Liana , Amador Jesus Tapia 
Published: May 2021

Reid's recipe for a finite abelian subgroup $G\subset \text{SL}(3,\mathbb{C})$ is a combinatorial procedure that marks the toric fan of the $G$-Hilbert scheme with irreducible representations of $G$. The geometric McKay correspondence conjecture of Cautis--Logvinenko that describes certain objects in the derived category of $G\text{-Hilb}$ in terms of Reid's recipe was later proved by Logvinenko et al. We generalise Reid's recipe to any consistent dimer model by marking the toric fan of a crepant resolution of the vaccuum moduli space in a manner that is compatible with the geometric correspondence of Bocklandt--Craw--Quintero-V\'{e}lez. Our main tool generalises the jigsaw transformations of Nakamura to consistent dimer models.Comment: 29 pages, published version
Les écrivains djadides turkmènes A. Kulmuhammedov et O. Vepaev sur eux-mêmes et sur leur époque

в статье раскрывается вопросы жизни и деятельности Туркменскиx писателeй-джадидoв А. Кульмухаммедова (1885-1931), наряду с О. Вепаевым (1885-1937). На основе выдержек из стихов О. Вепаева О. Тачназаров (1902–1942), со стороны бригады по проверкетуркменской литературы выступил большой рецензией под названием «Лицо врага» в журналe «Туркменоведение» за 1931 год гдe oн дает крайне отрицательную оценку его отношениям к советской действительности. Вслед за О. Тачназаровым исследователи советского периода характеризовали А. Кульмухаммедова и О. Вепаева как ярые националисты, пантюркисты и враги народа. Начиная с конца восьмидесятых годов прошлого века, постепенно начались меняться оценки ученых в положительную сторону в отношении литературного наследия указанных авторов.
This article presents some aspects of the life and the work of two Turkmen Jadid writers, A. Kulmuhammedov (1885-1931) and O. Vepaev (1885-1937), who were severely attacked in 1931 by the Brigade of the verification of the literature, and notably by O. Tachnazarov (1902-1942). He wrote long articles in the journal “Turkmen Studies” (Turkmenovedenie), where he denounced O. Vepaev as an enemy of the Soviet power based on some citations of his poems. During the entire Soviet period, the literary critics continued to give a very negative interpretation, as Tachnazarov did, of the writings of A. Kulmuhammedov and O. Vepaev, who were characterized as nationalists, panturkists, and enemies of the people. This is only by the end of the 1980’s that scholars have gradually changed their mind about these two writers, and that some positive judgement about their literary legacy started tobe published.
cet article éclaire quelques aspects de la vie et de l’oeuvre de deux écrivains djadides turkmènes, A. Kulmuhammedov (1885-1931) et O. Vepaev (1885-1937), qui furent l’objet d’une campagne de dénonciation par la brigade de vérification de la littérature turkmène en 1931, notamment de la part d’O. Tačnazarov (1902-1942). Dans la revue « Études turkmènes » (Turkmenovedenie), ce dernier s’appuie sur des extraits des poèmes d’O. Vepaev pour le dénoncer comme un ennemi du pouvoir soviétique. Dans l’esprit de cet article, A. Kulmuhammedov et O. Vepaev ont toujours été vus de façon très négative par les critiques littéraires de toute la période soviétique, qui ont continué de les caractériser comme des nationalistes, des panturquistes et des ennemis du peuple. Ce n’est qu’à partir de la fin des années 1980 qu’on a commencé à changer d’avis sur ces auteurs et à porter un jugement positif sur leur legs littéraire.

Le récit de voyage polonais : entre anthropologie et reportage
Authors: Monluçon Anne-Marie 
Published: May 2021

L’ouverture sur le vaste monde ne vient pas immédiatement à l’esprit lorsqu’on pense à la Pologne. Est‑ce parce qu’en France on associe volontiers l’intérêt pour les Ailleurs lointains à l’expérience coloniale ? Les continents non européens seraient ainsi partie intégrante de l’Histoire et des imaginaires britanniques, français, belges ou portugais, mais resteraient étrangers aux pays d’Europe centrale. Pourtant la littérature du voyage lointain peut se prévaloir, en Pologne, d’une tradition riche et ancienne et d’un succès jamais démenti auprès des lecteurs. Les articles réunis dans ce volume portent sur des auteurs illustres et consacrés (Bronisław Malinowski), mais aussi sur nombre d’auteurs ultra‑contemporains, récemment – ou pas encore – traduits (Andrzej Stasiuk, Joanna Bator). Ces travaux abordent les textes – récits, journaux, reportages, essais – dans leurs spécificités historiques et idéologiques : regard porté sur l’étranger par un pays qui n’a pas eu d’empire colonial lointain, qui a lui même longtemps subi le joug de puissances étrangères et qui a connu quarante‑cinq ans de totalitarisme. Les transferts culturels et les différentes formes de médiation sont au cœur des interrogations, puisque les écrivains voyageurs sont des médiateurs par excellence.
DESAIN LEMBAR AKTIVITAS SISWA (LAS) UNTUK MENINGKATKAN KEMAMPUAN SISWA MEMAHAMI KONSEP PEMBAGIAN PECAHAN DI SD NEGERI 095173 SIHEMUN
Authors: Pangaribuan Firman , Sinaga Juli Antasari Br. , Herman Herman 
Published: May 2021

Konsep pembagian pecahan masih merupakan konsep yang sulit bagi sebagian besar siswa. Banyak siswa SD maupun SMP belum dapat menulis dengan benar rumus pembagian pecahan . Siswa yang dapat menulis dengan benar rumus pembagian pecahan, tidak dapat menjelaskan mengapa demikian. Siswa dapat menyelesaikan masalah pembagian pecahan yang dinyatakan dalam soal cerita dengan menggunakan rumus pembagian pecahan, tetapi tidak memahami mengapa rumus itu berlaku. Guru dalam mengajarkan konsep pembagian pecahan tidak menuntut siswa kepada pembelajaran bermakna, hanya berbekal rumus, teori dan contoh soal yang diajarkan kepada siswa. Sumber belajar (buku pegangan siswa) belum seutuhnya memfasilitasi siswa untuk memahami konsep pembagian pecahan. Kegiatan pengabdian ini dilakukan pada tanggal 10 Agustus 2020 di Sekolah SD Negeri 095173 Sihemun Kec. Dolok Pardamean Kab. Simalungun. Target kegiatan ini adalah siswa kelas V SD yang berjumlah 20 orang. Kegiatan ini bertujuan untuk mengatasi kesulitan siswa dalam memahami konsep pembagian pecahan dan memberikan motivasi belajar bagi siswa. Kegiatan pengabdian ini dilakukan oleh dosen-dosen Program Studi Pendidikan Matematika FKIP Universitas HKBP Nommensen sebagai perencana, pelaksana dan sekaligus sebagai pengajar/ tutor. Kegiatan ini juga melibatkan 2 orang mahasiswa pilihan yang turut berpartisipasi dalam kegiatan ini. Metode diskusi lebih diutamakan dalam proses pembelajaran untuk menyelesaikan berbagai persoalan yang tertera pada LAS yang telah di desain oleh dosen. Kegiatan pengabdian ini terlaksana dengan baik dan efektif dalam menuntaskan kesulitan siswa memahami konsep pembagian pecahan. Hal ini tercermin dari indikator keberhasilan siswa mencapai nilai tuntas diatas KKM sebesar 90% dan 100% siswa memberikan respon positif atas proses pembelajaran dan 85% siswa menyatakan senang atas pembelajaran menggunakan media LAS yang didesain oleh tim dosen
Utopia, distopia... Pandemia!
Authors: Ramos Costa Pessoa Mirella , Teixeira de Melo Cristina 
Published: May 2021

Partindo de imagens dos sonhos de futuro do contemporâneo, recuamos historicamente para tentar mapear o enfraquecimento do pensamento utópico e a ascensão da imaginação distópica na atualidade. A partir do gesto genealógico, procuramos elucidar de que modo essa virada estaria relacionada com uma experiência temporal, que deu frutos a outras imagens de futuro na modernidade. Nesse sentido, utopia e distopia não simplesmente se contrapõem, são modos de imaginar o futuro estreitamente relacionados com dinâmicas de poder e modos de experienciar o tempo. O presentismo nos coloca isolados – física e politicamente – em um presente sufocado por previsões de futuro que se expandem num agora que parece se repetir. O presente torna-se o espaço de ação, embora a passagem do tempo não mais esteja associada ao alcance do lugar melhor ou à utopia moderna que irrompe no futuro para ser afeiçoada e concretizada no projeto coletivo imaginado para o amanhã.
Imagens que respiram
Authors: Souza e Silva Wagner 
Published: May 2021

Em 2009, o repórter-fotográfico Gustavo Pellizzon produziu a série “Fotografias que respiram”, propondo um discreto tangenciamento entre a imagem estática e a imagem em movimento. A partir da discussão gerada pelo caráter experimental desse trabalho, este ensaio tem como objetivo apontar considerações sobre a atual condição multimidiática do fotojornalismo, tomando como exemplo a série de reportagens “Um mundo de muros”, produzida em 2017 pelo jornal Folha de S. Paulo. As imagens dessa série, ao mesmo tempo em que exemplificam a imersão do fotojornalismo em um ambiente multimidiático, dialogam com o mesmo aporte estético utilizado por Pellizzon, o que permite classificá-las como um “fotojornalismo que respira”.
