Improving Density Functional Prediction of Molecular Thermochemical Properties with a Machine-Learning-Corrected Generalized Gradient Approximation
Authors: Wang Jingchun , Zhang DaDi , Xu Rui-Xue , Yam ChiYung , Chen GuanHua , Zheng Xiao
Published: May 2021

The past decade has seen an increasing interest in designing sophisticated density functional approximations (DFAs) by integrating the power of machine learning (ML) techniques. However, application of the ML-based DFAs is often confined to simple model systems. In this work, we construct an ML correction to the widely used Perdew-Burke-Ernzerhof (PBE) functional by establishing a semilocal mapping from the electron density and reduced gradient to the exchange-correlation energy density. The resulting ML-corrected PBE is immediately applicable to any real molecule, and yields significantly improved heats of formation while preserving the accuracy for other thermochemical and kinetic properties. This work highlights the prospect of combining the power of data-driven ML methods with physics-inspired derivations for reaching the heaven of chemical accuracy.

A CRIAÇÃO E O CONSUMO OBJETIFICADO DA ARTE PARA SATISFAÇÃO PESSOAL
Authors: De souza Hervely suely silva Alves
Published: May 2021

ResumoO presente artigo se propõe a relacionar as considerações de cunho psicanalítico e estético de Freud com a complementação de outros autores, levando-nos a capturar aspectos sobre a complexidade das reações humanas diante das representações artísticas. É por meio da complementação conceitual psicanalítica, estética e filosófica que realçaremos as determinações da capacidade de representação, assim como suas diferenciações; além disso, tentaremos descrever as dependências humanas e associar a aspectos artísticos e ver como este processo está ligado à satisfação. Uma possível padronização da forma com que lidamos com nossa realidade, nos levando ao passo da criação e da utilização de objetos artísticos, como uma forma histórica de como a humanidade tem se satisfeito diante de seu cotidiano amparada à arte.

A RUÍNA ESPIRITUAL DA HUMANIDADE EUROPEIA A PARTIR DA CRISE TEORICA DOS FUNDAMENTOS: A DENÚNCIA DE EDMUND HUSSERL AO MÉTODO POSITIVO DE EVIDENCIAÇÃO DO REAL
Authors: Mesquita Lucas Mattos
Published: May 2021

O presente estudo tem por objetivo apresentar o cenário de “crise das ciências” pela qual a Europa atravessava no início do século XX, e a qual se refere Husserl nos seus textos mais tardios, situando-a num contexto que exigia urgentemente a elaboração de uma ciência capaz de dar rigor aos demais saberes científicos. Em seu desenvolvimento, destaca-se a relação entre a crise teórica dos fundamentos e o colapso da cultura ocidental, mostrando, como, para Husserl, a crise dos sentidos estava intimamente ligada ao advento da ciência moderna que, historicamente, desenvolveu-se no positivismo. Por meio de uma pesquisa panorâmica dos movimentos positivistas da modernidade, apontamos, finalmente, para o contrassenso no modelo das Ciências do Espírito enquanto executoras de uma metodologia científico-natural, que, por sua vez, mostra-se extremamente nociva ao desenvolvimento espiritual da humanidade ocidental.
SOBRE O PROBLEMA METODOLÓGICO EM ARENDT: “PENSAR O QUE ESTAMOS FAZENDO”
Authors: Oliveira Reinaldo Francisco Jameli
Published: May 2021

O presente trabalho tece considerações sobre o problema metodológico que o pensamento político de Arendt confronta. Procuramos destacar que, embora seja errôneo atribuir a Arendt a posse de um método, no sentido tradicional do termo, podemos falar de um exercício de pensamento expresso no verbo “compreender” e no seu correlato “pensar o que estamos fazendo”. Iremos explorar a riqueza semântica que o compreender adquire nas reflexões da autora, apresentando o termo primeiramente como exercício de pensamento e, em seguida, como metáfora filosófica do espectador, procurando distinguir a compreensão do filósofo-espectador da compreensão do homem de ação, traçando os limites entre o filósofo e o político. Veremos que a recusa de Arendt a refletir sobre um método relaciona-se com a recusa a fazer de si um critério normativo para o pensamento alheio. Se Arendt ressalta a importância de pensar o que estamos fazendo, não fornece respostas prontas para este dilema, mas reserva ao interlocutor a tarefa de pensar por si mesmo e chegar a suas conclusões particulares.

Tekrarlı Ortalama Yardımıyla Renk İndirgeme ve Görüntü Erişimi
Authors: KILIÇASLAN Mahmut , TANYERİ Ufuk , DEMİRCİ Recep
Published: May 2021

Sayısal görüntülerden oluşan bir veri tabanından sorgulanan bir görüntünün aynısının veya benzerlerinin getirilmesi süreci görüntü erişimi olarak tanımlanır. Her ne kadar sayısal görüntü piksellerden oluşuyor olsa da sorgulama piksel düzeyinde değil, sayısal görüntüleri temsil eden vektörler düzeyinde yapılmaktadır. Görüntülerin vektörler ile temsil edilmesi özellik çıkarma süreci olarak adlandırılır ve içerik tabanlı görüntü erişiminin (İTGE) en önemli aşamasıdır. Özellik vektörünün temsil kabiliyetinin düşük olması sistemin performansının da düşük olması demektir. Gri ölçekli görüntülerin histogramları en tipik özellik vektörleridir. Diğer taraftan renkli görüntülerde üç ayrı kanal mevcut olduğundan, görüntüyü temsil edebilecek histogram üç boyutlu bir dizi oluşturur ki bu durum sistemin hesap maliyetini oldukça artıracaktır. Bu nedenle araştırmacılar renkli görüntülerdeki renk sayısını azaltma veya renk indirgeme yaklaşımını tercih etmişlerdir. Vektör kuantalama olarak adlandırılan renk indirgeme sürecinde ise her zaman aynı sonucu üretmek mümkün olmamıştır. Bunun nedeni ise bazı algoritmaların başlangıçta rastgele üretilen renk vektörleri ile çözüm aramalarıdır. Linde-Buzo-Gray (LBG), K-ortalamalar ve bulanık c-ortalamalar algoritmaları bu tür çözüm yaklaşımlarına tipik örneklerdir. Bu çalışmada tekrarlı ortalama tabanlı renk indirgeme yaklaşımı kullanılarak yeni bir görüntü erişim metodu önerilmiştir. Önerilen stratejide, öncelikle her bir renk kanalının histogramı üzerinden tekrarlı bir şekilde ortalamalar hesaplanmış ve çok seviyeli eşikler elde edilmiştir. Elde edilen eşikler kullanılarak RGB renk uzayı alt prizmalar şeklinde dilimlenmiştir. Oluşan alt prizmalar içinde kalan pikseller aynı sınıfa atanmış ve ilgili sınıftaki piksellerin ortalamaları kullanılarak renk indirgemesi yapılmıştır. Sınıf indisleri ve ilgili sınıflara tahsis edilen piksel sayıları yardımıyla tek boyutlu histogram elde edilmiştir. Son aşamada ise elde edilen sınıf tabanlı histogram özellik vektörü olarak atanmış ve içerik tabanlı görüntü erişimi gerçekleştirilmiştir. Önerilen algoritma ve LBG algoritması ile sonuçlar alınmış ve karşılaştırmalar yapılmıştır.

Authors: Sukhvinder Singh Oberoi , Avneet Oberoi
Published: May 2021

Background: Epidemiological studies in smokers indicate a dose-response relationship between the number of cigarettes smoked per day and the risk of developing certain smoking related diseases. The alkaloid nicotine is the major pharmacologically active substance in tobacco. Objective: To estimate the cotinine level excretion in urine among smoked and smokeless tobacco users and nonsmokers among the Indian population. Materials and methods: The study sample consisted of 250 subjects who were apparently healthy, asymptomatic and not using any drug. The study sample was divided into smoked tobacco users (bidi and cigarette), smokeless tobacco users, both smoked and smokeless tobacco users and controls (non-users of tobacco in the past or present). Results: The mean Cotinine level in urine was significantly (p – value < 0.05) more among smoked tobacco users in comparison to smokeless tobacco users and non-users of tobacco. Whereas, the mean Cotinine level in urine was significantly (p – value < 0.05) more among smokeless tobacco users in comparison to non-users of tobacco. Conclusion: The mean cotinine levels among smokers and both smokeless and smoked tobacco users were found to be higher than only smokeless tobacco users and non-users of tobacco.

Authors: Mokhefi Abderrahim , Bouanini Mohamed , Elmir Mohammed , Spitéri Pierre
Published: May 2021

The enhancement of the heat transfer in the stirred tank is a much-desired objective for accelerating certain physical and chemical parameters in the industrial field. From this basis, an attempt is made in this paper to investigate the effect of the wavy wall of a stirred tank on the hydrodynamic, thermal, and energetic behavior of an Al2O3-Water nanofluid. The stirred tank has a flat bottom, and it is equipped with an anchor stirrer. A hot temperature has been imposed on the tank wall, and the agitator has been assumed adiabatic, where the nanofluid has a cold temperature at the initial instant. The laminar flow was governed by the equations that describe the forced convection, and it was solved by the finite element method. The numerical simulation results showed a considerable acceleration in the heat transfer inside the stirred tank by increasing the amplitude of the wavy wall and increasing the nanoparticle concentration. However, there has been a remarkable increase in the stirring power number. This contribution aims to increase thermal efficiency, especially in the chemical and petrochemical fields, to obtain a better yield of certain chemical reactions and mass transfer depending on the heat.

NATIVESPEAKERISM AND WORLD ENGLISHES: TEACHERS PERCEPTION TOWARDS NON-NATIVE ENGLISH VARIETIES
Authors: Silalahi Ronald Maraden
Published: May 2021

In the last decade, the development of information technology confirms English as a Lingua Franca used by native English speakers and nonnative English speakers. English in a global context has triggered the emergence of new English variants, resulting from the assimilation of English into a local language known as World Englishes. On the other hand, Teaching English as a Foreign Language (TEAFL) in Indonesia is still oriented towards the ideology of nativespeakerism which believes that TEAFL should be done by Native English-Speaking Teachers (NEST) because they are believed to have better linguistic competence and contextual understanding than Nonnative English-Speaking Teachers (NNEST). This article is directed to determine the perceptions of English teachers in Indonesia regarding the world Englishes phenomenon. This research is qualitative research with 20 informants consisting of 10 Nonnative English-Speaking Teachers and 10 Native English-Speaking Teachers. Four Focus Group Discussions (FGDs), each consisting of 5 informants, will be conducted to gather as much information as possible related to teachers’ perceptions. This research is expected to provide an overview of foreign language teaching in Indonesia. The results showed that nativespeakerism has a strong correlation with the world Englishes phenomenon. In the Indonesian context, this is shaped by the stigma that forms in society. This research is expected to enrich teaching studies, specifically in teaching foreign languages.
FEAR RHETORIC IN THE ONLINE NEWS DISCOURSE ON THE COVID-19 PANDEMIC IN TEUN VAN DIJK’S CRITICAL DISCOURSE ANALYSIS
Authors: Rovino Dery , Nur Afifah Fadhilah , Aqwya Aningrum Kusuma Wardani Tiara
Published: May 2021

The news media, once thought to be only as a tool of information delivery, has subtly shifted its roles as an agent of (de)constructing thoughts, introducing, or denoting fear especially in appalling news. This raises a question whether the news on the COVID-19 pandemic is only for transmitting news updates on the pandemic condition or agenda-driven. However, research tapping into the imbued messages in language complexity in this context seems minimal. This study aims to uncover the language elements that sign fear in a news text. This research focuses on how fear is imbued in three online English-language newspaper articles in Indonesia published by the Jakarta Post, thereby the rhetoric of fear. The three articles discussed the spread of COVID-19 in Indonesia.  In this study, CDA is devised to reveal the traces of fear-embedded language choices found in the three online newspaper articles. Researchers used the critical analysis discourse model of Teun A. Van Dijk (1993) and the three elements of discourse (1993): micro, macro, and superstructure. Findings indicated that there were common uses of euphemism, dysphemism, and orthophemism to refine the language being conveyed. This study classified euphemism into five objectives: (1) evasive maneuver to prevent mass panic; (2) speech refinement to soften offence, insults, and/ or other language expressions that may result to humiliation; (3) diplomacy tool; (4) language replacement for taboo or vulgar language choices or those endowed with negative connotation (5) tool for satire, sarcasm and subtle criticism. This study also revealed some linguistic decisions, such as lexicon choices and strategies on sentence construction, subtly evident not only to impose fear, but at the same time to dispose it. Researchers hope that this study may assist the readers in pinpointing subtleties in author’s tone and tendency.
