Man and nature are two inseparable elements of the world, and the unbreakable connection and coexistence between them is the origin of all kinds of literary works. From ancient times to the present day, we often see poems about nature both in Russian and Persian literature. Using the Natural objects and phenomena in the form of myths and symbols in literary works and giving them personality have various reasons, including political ones. Sometimes poems may be composed under the influence of a poet from another country. This influence can be seen in contemporary Iranian literature. Among the contemporary Iranian poets who are very familiar with the ideas and works of Russian poets and writers is the Iranian naturalist (пейзажист) poet Shafiei Kadkani. He composed his poem “Happy Journeys!”) based on Lermontov’s “The Rock” and “The black Clouds” poems. Both poets have used natural images such as plant (растение), breeze (ветерок), blossoms (цветения), rain (дождь), desert (пустыня), dust (пыль), horror desert (пустыня ужаса), rock / cliff (утес) and black clouds (тучи), which have a symbolic role. By comparing the poems, we can see that they are similar in terms of content and have the same message. And some of the symbols of Shafiei Kadkani are the same as the symbols of Lermontov, such as the desert, or they are chosen in terms of meaning very close to the symbols of Lermontov, such as “rock / cliff and milkvetch” or “small clouds and breeze”, as well as the dynamic movement of small clouds and breeze, which are the symbol of transition and change. Like Lermontov, Shafiei Kadkani also complains about the situation of his society, but symbols like “blossoms and rain” at the end of Shafiei Kadkani’s poem, unlike Lermontov’s poems, promise the morning of freedom, prosperity and transition, but with doubts.

In al-Ğāḥiẓ’s treatise Kitāb Faḫr al-Sūdān calā al-Biḍān, the title of which in the already classic Polish study on Arabic literature was translated as The Superiority of Blacks over Whites, or Treatise on the Superiority of Blacks over Whites, the author of the work lists the characters of black inhabitants of the caliphate; among them he evokes al-Ḥayquṭān, whom he presents as a poet and a preacher of Abyssinian origin. He also quotes al-Ḥayquṭān’s poem, which is a paean to the courage and valor of the Abyssinians, referring to important events that took place in the Arabian Peninsula just before the birth of the Prophet Muḥammad. In modern times, al-Ḥayquṭān’s poem is used in popular publications and online forums as a historical example of a reaction to racism and a reason to be proud of the bravery of the poem’s dark-skinned characters, as well as the example of literary achievement of the inhabitants of the caliphate of African descent. The purpose of this article is to refer to the historical events mentioned in the work of the black poet, present him in the context of the few surviving Arabic sources, explore the potential circumstances of the creation of the work and reflect on the actual circumstances of its creation as described by al-Ğāḥiẓ.

This essay focusses on references to the sixteenth-century black poet and scholar Juan Latino in African American journals in the 1920s–1940s. Although Juan Latino is largely forgotten in the present day, publications such as the Journal of Negro History and the New Negro referred to the poet as an important figure in the intellectual history of the African diaspora. My essay posits Juan Latino (both the historical figure and an early modern play about him) as an alternative exemplar of blackness in early modern Europe to that found in Othello. By turning to Juan Latino instead of to Othello, scholars in the 1920s–1940s were able to suggest a transnational and transhistorical black diasporic identity linked with African American solidarity with the Republican cause in the Spanish Civil War.

Attipat Krishnaswamy Ramanujan (1929-1993), needs no introduction in the word of Indian English Poetry. His poems are liked by every person because his poems are either replete with the humanistic approach or his poem have autobiographical elements. He was a poet, translator, playwright and folklorist. He belonged to a Hindu family. He was a trilingual writer who wrote in English, Tamil and Kannada. He has interpreted some works written in Sanskrit and Tamil bases on some classical and modern variants. He had four poetry collections to his credit: The Striders (1966), Relations (1971), Second Sight (1986), and The Black Hen (1995). Ramanujan’s poems are so easy and personal that these poems touch the heart of reader.

The article describes peculiar features of aesthetics and poetics of “sadistic verses” in the creative work of modern Austrian poet E. Yandle, Russian author A. Grygoriev and Belarusian masters of artistic word V. Zhybul and V. Burlak. Using the means of grotesque, carnivalization, illogic and black humour the authors show their protest against an excessive normativity and nihilistic pathos to modern reality with its standards, and create a peculiar lyrical hero – a weirdo, an eccentric person who falls into the chain of catastrophes, crashes and accidents.

Davíð Stefánsson (1895-1964) is a poet whose work marks a turning point in early twentieth-century Icelandic literature. This essay offers five new English translations from his first collection Black Feathers (Svartar Fjaðrir,1919) and introduces a new decadent perspective. Decadence is widely regarded as flourishing in emergent modern societies, but, as this essay shows, its influence extended beyond western Europe. Written in a remote place, Stefánsson’s decadence speaks to an aesthetic of emptiness and atemporality. These poems broaden our conception of decadence and evidence a rich cultural hybridity, showing the influence of various traditions including symbolism, the Gothic, folk-songs, and decadence.

Women in the modern era have been defined as being revolutionary and opposed to the traditional representation of their lives. Alice Walker (February 1944-) a Pulitzer Prize-winning figure is an African-American novelist, critic and poet who has vigorously defended women's modernist innovations and African American civil rights in her works. Her novel The Color Purple (1982) explores the African American female experience through the life and struggles of the narrator of the novel. What distinguishes The Color Purple is the very feature of psychological state of the heroine whilst struggling for her minimal rights of being a woman and black. The heroine of the novel Celie is revolutionary and anti-traditional. Walker planted her own personal experience within The Color Purple through the sufferings and traumatic life of the female characters.Walker through “Womanism”, a term coined by herself representing Black feminism, combines critical elements in The Color Purple, namely the importance of black history and heritage and the centrality of female creativity and competence in that heritage, which are often symbolized by quilts, sisterhood, liberation, self-identity, double consciousness and other symbols. Further through exhibiting African American woman’s twice-oppressed state, as they were double-discriminated racially and sexually by Americans, on the one hand by white Americans, on the other, by their fellow black male counterparts. The epistolary style of The Color Purple is probably an essential feature of modern literary output. The letters are used to manifest Celie and other characters’ lives to readers. Furthermore, within The Color Purple, Walker employs the very modern African American literary feature which is “Neo-Slave Narrative”. Through Neo-Slave Narrative, she displays her black female characters’ still-enslaved status in the modern era to form a juxtaposition between narrations of her fellow oppressed black women and Slave-Narrations of enslaved African Americans like Harriet Jacobs and Sojourner truth.

The article considers the work of the Chinese poet Hai Zi (mostly based on works not translated into Russian) as a characteristic example of the spiritual and artistic influence of Sergei Yesenin's work on modern Chinese poetry. The poetic dialogue of Hai Zi and S. Yesenin is considered from the point of view of tanatological poetics, which allows us to present their work as a single meta text, developing various variations of tanatopoetics in order to achieve absolute self-identification by synthesising “self” – death – art. The category of death is considered as the integral basis of the work of S. Yesenin and Hai Zi, which ultimately leads to the realisation of their personal attitude to death as the ontological, epistemological and axiological basis of life and creative work. The article justifies that the “romance with death” of S. Yesenin and Hai Zi is a manifestation of their life-building strategy, consonances in motif and figuration are revealed in the aspect of tanatological poetics, taking into account the different nature of those motifs: the spontaneous-organic feeling of death in S. Yesenin and the tanatological ideology of Hai Zi, based on the synthesis of Western philosophy, Confucianism, Taoism. Particular attention is paid to the consideration of S.Yesenin's poem “The Black Man” and the poem “Spring. Ten Hai Zi” as works that expose the key settings of the poets' tanatological discourse, as well as an analysis of Hai Zi's poem "Life Was Interrupted" as prisms for the reinterpretation of S. Yesenin's life and work within the framework of the tanatological paradigm of "Chinese Yesenin" and the most important act of semiotisation of life and creative work of the Chinese youth, when suicide is positioned as the final statement.

British literature, especially poetry has experienced different phases and showed the unique faces from the early periods to what called modernity era. The multi-facetted poetry is inflected by the dynamic atmospheres faced by Britain as results of the responses of poetic artists to the ups and downs of British history, especially the industrial changes and the brutality of World War I and II. Poets responded the political, social and cultural waves with their own unique styles and moods. The traumatic Wars and their casualties were not the sole themes during the war or post war era poetry, some poets reacted the issues of their own ways. This paper will discuss the reaction of some British poets to the wars. The discussion sections will be parted into the general responses, and also the analysis of two post war poets namely Adrian Henry and James Berry to represent their era of 1960 and 1980. This study reveals some findings that the poets experienced WWI and WWII responded the wars in such dramatic and gloomy ways as they are closely affected by the effects of 1915-1945 wars. Adrian Henry lived in the era post-modern, 1960s, the effect should have recovered. His poetic style speaks itself. James Berry, a Black immigrant poet, voices his root, past experiences and hope for a new life. Despite the style and theme, they all flourish British poetry with their own uniqueness.Keywords: British poetry, postwar, postmodern, Adrian Henri, James Berry

Semiotics is one of the modern critical methods of postmodernism in which through signs, it digs deep into the depth of a text.Sherko Bekas’s Rangdan collection is one of the collections in which signs are used abundantly because the poet uses colours 1219 times and many words are used as signs. The most used colours are blue, black, red and white. Each of these colours has its own meanings and implications in different cultures and texts; it has its role on people’s views, and it depicts roles of colours in relations to the lives of people. Hence, the use of Rangdan, which means the collection of colours, is not without purpose, but it has everything to do with environmental, psychological, intellectual and cultural aspects of life.

Les modèles d'intelligence artificielle (IA) actuels ont fait leurs preuves dans la résolution de diverses tâches, telles que la classification, la régression, le traitement du langage naturel (NLP) et le traitement d'images. Les ressources dont nous disposons aujourd'hui nous permettent d'entraîner des modèles d'IA très complexes pour résoudre différents problèmes dans presque tous les domaines : médecine, finance, justice, transport, prévisions, etc. Avec la popularité et l'utilisation généralisée des modèles d'IA, la nécessite d'assurer la confiance dans ces modèles s'est également accrue. Aussi complexes soient-ils aujourd'hui, ces modèles d'IA sont impossibles à interpréter et à comprendre par les humains. Dans cette thèse nous nous concentrons sur un domaine de recherche spécifique, à savoir l'intelligence artificielle explicable (xAI), qui vise à fournir des approches permettant d'interpréter les modèles d'IA complexes et d'expliquer leurs décisions. Nous présentons deux approches, STACI et BELLA, qui se concentrent sur les tâches de classification et de régression, respectivement, pour les données tabulaires. Les deux méthodes sont des approches post-hoc agnostiques au modèle déterministe, ce qui signifie qu'elles peuvent être appliquées à n'importe quel modèle boîte noire après sa création. De cette manière, l'interopérabilité présente une valeur ajoutée sans qu'il soit nécessaire de faire des compromis sur les performances du modèle de boîte noire. Nos méthodes fournissent des interprétations précises, simples et générales à la fois de l'ensemble du modèle boîte noire et de ses prédictions individuelles. Nous avons confirmé leur haute performance par des expériences approfondies et étude d'utilisateursCurrent state-of-the-art Artificial Intelligence (AI) models have been proven to be verysuccessful in solving various tasks, such as classification, regression, Natural Language Processing(NLP), and image processing. The resources that we have at our hands today allow us to trainvery complex AI models to solve different problems in almost any field: medicine, finance, justice,transportation, forecast, etc. With the popularity and widespread use of the AI models, the need toensure the trust in them also grew. Complex as they come today, these AI models are impossible to be interpreted and understood by humans. In this thesis, we focus on the specific area of research, namely Explainable Artificial Intelligence (xAI), that aims to provide the approaches to interpret the complex AI models and explain their decisions. We present two approaches STACI and BELLA which focus on classification and regression tasks, respectively, for tabular data. Both methods are deterministic model-agnostic post-hoc approaches, which means that they can be applied to any black-box model after its creation. In this way, interpretability presents an added value without the need to compromise on black-box model's performance. Our methods provide accurate, simple and general interpretations of both the whole black-box model and its individual predictions. We confirmed their high performance through extensive experiments and a user study

Servicemen's Readjustment Act of 1944, commonly known as the GI Bill, was a transformative piece of legislation signed by President Roosevelt intended to help WWII Veterans transition successfully from soldier to citizen. Often dubbed the magic carpet to the middle class, provisions of the bill granted eligible veterans free college tuition, job training and placement, generous unemployment benefits and a low interest, no money down loan for a home or business. The effects of this bill were widespread; it touched eight out of ten men born in the 1920's. Much is known of impact GI Bill benefits had on white veterans, but less is known of how black veterans, who accounted for one in thirteen WWII Veterans, were able to use them. This paper examines barriers black veterans faced to access and use the housing benefit, and examines the possible intergenerational impacts such barriers had on the wealth and homeownership status of African Americans today.

Critics often credit Ezra Pound and his Imagist movement for the development of American poetics. Pound’s interest in international arts and minimalist aesthetics of cross-cultural poetry gained the attention of prominent writers throughout Modernist and Post-Modern periods. From writers like Wallace Stevens and Gertrude Stein to later poets like Jack Kerouac and Gary Snyder, image and precise language has shaped American literature. Few critics have praised Eastern cultures or the Imagist poets who adopted an East-Western form of poetics: Amy Lowell and William Carlos Williams. Studying traditional Eastern painting and short-form poetry and interactions with personal connections to the East, Lowell and Williams adapt then progress aesthetic fusions Pound began and abandoned through his interpretation of Eastern art. Like Pound, Lowell and Williams illustrate a mix of form, free-verse language, and modernized poetics to not only imitate Eastern art but to create poetics of international discourse which shape American Modernism.

Lately Unmanned Aerial Systems (UAS) are used more frequently in surveying. With broader use comes higher demands on the uncertainty in such measurements. The post processing software is an important factor that affects the uncertainty in the finished product. Therefore it is vital to evaluate how results differentiate in different software and how parameters contribute. In UAS-photogrammetry images are acquired with an overlap which makes it possible to generate point clouds in photogrammetric software. These point clouds are often used to create Digital Terrain Models (DTM). The purpose of this study is to evaluate how the level of uncertainty differentiates when processing the same UAS-data through block adjustment and dense image matching in two different photogrammetric post processing software. The software used are UAS Master and Pix4D. The objective is also to investigate how the level of extraction in UAS Master and the setting for image scale in Pix4D affects the results when generating point clouds. Three terrain models were created in both software using the same set of data, changing only extraction level and image scale in UAS Master and Pix4D respectively. 26 control profiles were measured with network-RTK in the area of interest to calculate the root mean square (RMS) and mean deviation in order to verify and compare the uncertainty of the terrain models. The study shows that results vary when processing the same UAS-data in different software. The study also shows that the extraction level in UAS Master and the image scale in Pix4D impacts the results differently. In UAS Master the uncertainty decreases with higher extraction level when generating terrain models. A clear pattern regarding the image scale setting in Pix4D cannot be determined. Both software were able to produce elevation models with a RMS-value of around 0,03 m. The mean deviation in all models created in this study were below 0,02 m, which is the requirement for class 1 in the technical specification SIS-TS 21144:2016. However the mean deviation for the ground type gravel in the terrain model created in UAS Master at a low extraction level exceeds the demands for class 1. This indicates all but one of the created models fulfil the requirements for class 1, which is the class containing the highest requirements.Obemannade flygfarkostsystem (eng. Unmanned Aerial Systems, UAS) används allt mer frekvent för datainsamling inom geodetisk mätning. I takt med att användningsområdena ökar ställs också högre krav på mätosäkerheten i dessa mätningar. De efterbearbetningsprogram som används är en faktor som påverkar mätosäkerheten i den slutgiltiga produkten. Det är därför viktigt att utvärdera hur olika programvaror påverkar slutresultatet och hur valda parametrar spelar in. I UAS-fotogrammetri tas bilder med övertäckning för att kunna generera punktmoln som i sin tur kan bearbetas till digitala terrängmodeller (DTM). Syftet med studien är att utvärdera hur mätosäkerheten skiljer sig när samma data bearbetas genom blockutjämning och tät bildmatchning i två olika programvaror. Programvarorna som används i studien är UAS Master och Pix4D. Målet är också att utreda hur vald extraktions nivå i UAS Master och vald bildskala i Pix4D påverkar resultatet vid generering av terrängmodeller. Tre terrängmodeller skapades i UAS Master med olika extraktionsnivåer och ytterligare tre skapades i Pix4D med olika bildskalor. 26 kontrollprofiler mättes in med nätverks-RTK i aktuellt område för beräkning av medelavvikelse och kvadratiskt medelvärde (RMS). Detta för att kunna verifiera och jämföra mätosäkerheten i modellerna. Studien visar att slutresultatet varierar när samma data bearbetas i olika programvaror. Studien visar också att vald extraktionsnivå i UAS Master och vald bildskala i Pix4D påverkar resultatet olika. I UAS Master minskar mätosäkerheten med ökad extraktionsnivå, i Pix4D är det svårare att se ett tydligt mönster. Båda programvaror kunde producera terrängmodeller med ett RMS-värde kring 0,03 m. Medelavvikelsen i samtliga modeller understiger 0,02 m, vilket är kravet för klass 1 från den tekniska specifikationen SIS-TS 21144:2016. Medelavvikelsen för marktypen grus i UAS Master i modellen med låg extraktionsnivå överskrider dock kraven för klass 1. Därmed uppnår alla förutom en av terrängmodellerna kraven för klass 1, vilket är den klass med högst ställda krav.

La littérature persane est surtout connue en Occident par les excellentes traductions en français d'illustres poètes classiques comme Omar Khayyam, Roumi, Hafîz. Genre majeur de la littérature persane, la poésie s'impose pendant des siècles avec ses règles draconiennes de prosodie et de versification. Dans les années 1930, une jeune génération de poètes, sensibles aux transformations sociales, politiques, culturelles et ayant découvert la poésie et la littérature occidentales, s'est engagée dans une lutte systématique contre ces règles intangibles. Le pionnier de ce mouvement est Nimâ Yshij. Il rejette les règles de la poésie classique, aussi bien en ce qui concerne la métrique que la place de la rime. Ahmad Shâmlu, disciple de Nimâ, va plus loin en refusant même la prosodie. En rupture permanente, Shâmlu a marqué la poésie moderne persane, par son œuvre, par ses idées et par ses attitudes. Soucieux des événements de son temps et de sa société, ce poète, traducteur et directeur de revues, a lutté toute sa vie pour ses idéaux humanistes. Une anthologie de ses œuvres traduites en français permettra de faire découvrir aux amateurs ce grand poète persan moderne et contemporainPersian literature is best known in the West by the excellent French translations of famous classical poets like Omar Khayyam, Rumi, Hafeez. As a major genre of Persian literature, poetry has for centuries imposed draconian rules of prosody and versification. In the 1930s, younger generation of poets, sensitive to social, political and cultural changes, discovered Western poetry and literature, and engaged in a systamtic struggle against these intangible rules. the pioneer of this movment in Nima Yshij. Her rejected the rules of classical potry, where both versification and rhyme are concerned. Ahmad Shâmlu, a disciple of Nima, goes even further by refusing prosody. Breaking constantly with traditon, Shâmlu has left his mark on modern Persian poetry, in his work, and by his ideas and attitudes. Mindful of the events of his time and of his life for his humanistic ideals. An antthology of his works translatedinto French will enable poetry-lovers to discover this great modern contemporary Persian poet

The post-traumatic stress disorder (PTSD) affects a portion of subjects exposed to a traumatic event. This disorder leads to long-term alterations in the hypothalamus-pituitaryadrenal (HPA) axis, autonomic and cognitive function. The aim of our study was to evaluate whether the animal model of PTSD proposed for rats could be used in mice and, to evaluate the effect of benzodiazepine, tricycle antidepressant and selective serotonin reuptake inhibitor drugs in the PTSD model. For this we realized the following experiments: Experiment 1- The test consisted of exposure the male mice to inescapable electric footshock (0.3 mA) in the black side (BS) of the black-white box (BW). In the 7th, 14th and 21th day, mice were reexposed to the traumatic reminder on the white side (WS) or BS for 2 min, without footshock. In the 29th day, the animals were submitted to elevated plus-maze (EPM) for record the anxiety indexes [percentage of open arm entries (%OA) and percentage of open arm time (%OT) and as well as general locomotor activity, closed arm entries (CE)]. On day 34 the same animals were submitted to BW test for record the latency to escape (LE) from WS and time spent on WS of the BW box. Experiment 2 the same procedure of experiment 1 was performed, except that the animals were re-exposed at 7th, 14th e 21th days to reminder situation only in WS of BW box for 2 min, without footshock. On day 29th, the animals were exposed to EPM, 30 min after receiving treatment with midazolam. In 34th day the same animals after receiving treatment with midazolam were submitted to BW box test. Experiment 3, 4 and 5 - the same procedure was adopted from experiment 2, except that in 29th day, the animals were not submitted to EPM test and on 34th day 30 minutes after treatment with midazolam, imipramine and sertraline were submitted to BW box. Two-way ANOVA (stimulus x place remainder or treatment) followed by Duncan test showed that PTSD model increased anxiety in mice (P<0.05). The re-exposure in BS promoted anxiogenic-like effect extinction of the model. The midazolam treatment (1.0 and 2.0 mg/kg, i.p.) produced anxiolytic-like effect in maze-mice (P < 0.05) and the 0.5 mg/kg decreased latency to escape of WS (P < 0.05) of BW box and increased the exploratory activity, suggesting involvement of this GABA-benzodiazepine agonist on this PTSD modulation. The EPM test does not interfere in the evaluation of the BW test. It is important to note that no other behaviors were significantly altered by imipramine per se (P < 0.05). The sertraline (5.0 mg/kg), selective serotonin reuptake inhibitor, produced anxiolytic-like effect in the BW test (P < 0.05) and increase exploration activity. These results suggest that the employed PTSD model to study neurobiological disturbances associated with this disorder.
O Transtorno de Estresse Pós-Traumático (TEPT) afeta uma parcela de indivíduos que são expostos a um evento traumático. Este distúrbio induz em longo prazo alterações no eixo HPA, autonômicas e cognitivas. O objetivo deste estudo foi avaliar se o modelo animal de TEPT proposto para ratos poderia ser utilizado em camundongos e investigar o efeito dos fármacos benzodiazepínico, antidepressivo tricíclico e inibidor seletivo da recaptação de serotonina, no modelo de TEPT. Para isso realizamos os seguintes experimentos: Experimento 1- O teste consistiu em submeter camundongos machos, Suíço-albino ao choque inescapável (0,3mA) nas patas no lado escuro (LE) da caixa claro-escuro (CE). No 7º, 14º e 21º dia os camundongos foram reexpostos a situação de lembrança no lado claro (LC) ou LE da caixa por 2 min, sem choque. No 29º dia os animais foram expostos ao labirinto em cruz elevado (LCE), para o registro dos índices de ansiedade [porcentagem de entradas (%EBA) e de tempo gasto nos braços abertos (%TBA) e atividade locomotora, entrada nos braços fechados (EBF)]. No 34º dia os mesmos animais foram submetidos ao teste CE para o registro da latência de fuga (LF) e do tempo gasto no LC da caixa CE. Experimento 2 o mesmo procedimento do experimento 1 foi adotado, exceto que os animais foram reexpostos no 7º, 14º e 21º dia a situação de lembrança apenas no LC da caixa por 2 min, sem choque. No 29º dia os animais, 30 min após receberem tratamento com midazolam, foram expostos ao labirinto em cruz elevado (LCE). No 34º dia os mesmos animais após receberem o mesmo tratamento farmacológico, foram submetidos ao teste CE. Experimento 3, 4 e 5 o mesmo procedimento do experimento 2 foi adotado, exceto que no 29º dia os animais não foram submetidos ao LCE e no 34º dia, 30 min após receberem tratamento com midazolam, imipramina e sertralina foram submetidos ao teste CE. A ANOVA de duas vias (estímulo x local da SL ou tratamento) seguido do teste de Duncan mostrou que o modelo de TEPT produziu aumento da ansiedade nos camundongos (P < 0,05). As reexposições no LE promoveram extinção do efeito ansiogênico do modelo. O tratamento com midazolam (1,0 e 2,0 mg/kg) produziu efeito ansiolítico no LCE (P < 0,05), e a dose de 0,5 mg/kg reduziu a latência de fuga do ambiente claro (P < 0,05) no teste CE e aumentou a atividade exploratória, sugerindo o envolvimento deste agonista GABA-benzodiazepínico na modulação do TEPT. O LCE não interferiu na avaliação do teste CE. A imipramina não apresentou efeito sobre os camundongos (P > 0,05), ou seja, ausência de efeito deste antidepressivo tricíclico nos sintomas do TEPT. A sertralina (5,0 mg/kg) produziu efeito ansiolítico no teste CE (P < 0,05) e aumento na atividade exploratória, mostrando o envolvimento deste inibidor seletivo da recaptação de serotonina na modulação do modelo. Estes resultados sugerem que o modelo de TEPT utilizado poderá ser empregado para o estudo das alterações neurobiológicas envolvidas neste distúrbio.

Comme nombre de cités industrielles Firminy (Loire) est au sortir de la seconde guerre mondiale une ville où insalubrité et surpeuplement règnent. Les amitiés tissées dans les réseaux de résistance, la recherche d’un terrain propice aux expériences amènent un ancien ministre de la Reconstruction, Eugène Claudius-Petit, déjà député, à briguer le poste de maire. Elu en 1953, il lance très rapidement une vaste opération de rénovation et de restructuration de la cité. Alors que les grands ensembles fleurissent dans les banlieues des grandes villes, il impulse un programme de ce type dans une cité de 25 000 habitants. Il fait appel à une équipe resserrée d’amis architectes, Roux, Sive, Delfante pour concevoir un nouveau quartier suivant les idées de la Charte d’Athènes, Firminy-Vert. Opération de secteur industrialisé, le chantier est aussi un modèle d’industrialisation et de préfabrication. La construction de plus de 1000 logements est lancée et a pour ambition d’offrir aux locataires une nouvelle manière d’habiter génératrice d’une nouvelle société. Architecture, urbanisme, sont mis au service d’une renaissance de la cité. Bâtissant un quartier ils incluent dans le projet des équipements collectifs : écoles, commerces, stade et même une maison de la Culture. Le Corbusier est invité et conçoit pour cette cité une Maison de la Culture, un stade, une unité d’habitation et une église dont le chantier, étalé sur plus de 30 ans, vient de connaître son achèvement offrant à la cité une reconnaissance patrimoniale internationale. La communauté rêvée et attendue dans cet habitat moderne laisse place à la communauté réelle qui s’approprie et transforme ce quartier trop souvent oubliéFirminy a small mining community in the outskirts of Saint-Etienne (France) at the end of WW2 is no different from most industrial cities, the stigma of poverty, human misery, overcrowded and unplanned developments are everywhere. Eugene Claudius Petit, in charge of the post war country rebuilding effort will leverage its connections with the best town planners and Architects to launched some new architectural and planning developments in Firminy, a City were he has been elected mayor in 1953. The renewal and redevelopment endeavor is mimicking in a city of just 25 thousand inhabitants, the projects that at a much broader scale flourish throughout the continent. But the project is also sticking by Eugene Claudius Petit to recruit the best architects and town planner of the time. Roux, Selfante and Sive will help red-define the entire city based on the 95-point program of the Athens chart. Firminy-Vert will also prove to be the perfect model and case study for new building methods experiments and the use of prefabricated element in particular. One thousand accomodations are completed, offering as much useful amenities as possible is a key element in order to create a new way of living, even a new sense of community and society. Architects, town planners are working together to rebuild, regenerate, hoping for a complete Renaissance. Public amenities such as a sport center, a cultural and communities center, a church (which as just been completed 30 years after the ground breaking and give the opportunity for this now coherent development to be world heritage. The idealistic community comes to live translated into a very real community that generates life in a neighborhood too often undervalued and almost forgotten

This chapter argues that the “Negro Renaissance” in Harlem and Chicago was spawned by Pan-Africanism, which suggests the belief that black people all over the world share an origin and a heritage, that the welfare of black people everywhere is inexorably linked, and that the cultural products of blacks everywhere should express their particular fundamental beliefs. The chapter describes the quandary of renaissance artists, intellectuals, and entertainers who drew inspiration from the vernacular yet professed allegiance to the styles and tone of high or modern culture. It also notes that the black arts manifesto of poet Hughes' generational cohort exemplifies the refusal of these artists and intellectuals to accept the hierarchical oppositional distinction between high (middle class, northern, urban) and low (folk, spiritual, rural).

In this essay, Griet Bonne examines what Rubens' modern remediation can teach us about reproducibility in the current post-digital age. Between Rubens' 300th and 400th birthday celebration, in 1877 and 1977 respectively, mechanical reproductions increasingly defined our perception and reception of art. Reproduction media used various visual strategies to translate the artworks' narratives into a modern perspective. In addition, the altered formal and material appearance of the images resulted in new interpretations of the artworks, based entirely on the medium-specific properties of the reproduction.

Abstract We present the Verse library with the aim of making hybrid system verification more usable for multi-agent scenarios. In Verse, decision making agents move in a map and interact with each other through sensors. The decision logic for each agent is written in a subset of Python and the continuous dynamics is given by a black-box simulator. Multiple agents can be instantiated, and they can be ported to different maps for creating scenarios. Verse provides functions for simulating and verifying such scenarios using existing reachability analysis algorithms. We illustrate capabilities and use cases of the library with heterogeneous agents, incremental verification, different sensor models, and plug-n-play subroutines for post computations.

AbstractMany methods have been developed to understand complex predictive models and high expectations are placed on post-hoc model explainability. It turns out that such explanations are not robust nor trustworthy, and they can be fooled. This paper presents techniques for attacking Partial Dependence (plots, profiles, PDP), which are among the most popular methods of explaining any predictive model trained on tabular data. We showcase that PD can be manipulated in an adversarial manner, which is alarming, especially in financial or medical applications where auditability became a must-have trait supporting black-box machine learning. The fooling is performed via poisoning the data to bend and shift explanations in the desired direction using genetic and gradient algorithms. We believe this to be the first work using a genetic algorithm for manipulating explanations, which is transferable as it generalizes both ways: in a model-agnostic and an explanation-agnostic manner.

The paper reports removal of organic Black (Key) dye from real printing wastewater using nano zero valent iron particles as a catalyst in Fenton-like treatment. The degradation efficiency of Black diazo dye via Fenton-like treatment is reported to be 61% under established optimal process conditions: [Fe2+] = 0.75 mgL-1, pH = 2, [H2O2] = 1 mM, within a reaction time of 75 min. The absorption spectra of Black dye clearly indicate that dye degradation is a slow process with difficult decomposition of aromatic structures, due to the cleavage of diazo bonds by hydroxyl radicals. The physico-chemical characterizations (measurements of pH, electrical conductivity, temperature, turbidity, chemical oxygen demand, biochemical oxygen demand, total organic carbon, anionic surface-active substances and phosphorus content) as well as toxicity study (Vibrio fischeri bacteria) revealed the complex nature of printing effluent. Increased conductivity and biochemical oxygen demand content after Fenton treatment imply the formation of various byproducts and intermediates, formed in a solution during dye degradation. The mineralization percentage of Black dye of 58% is followed with 47% of chemical oxygen demand reduction. Results of toxicity test on Vibrio fischeri bacteria indicate that both untreated and treated printing effluents belong to moderate toxic samples with 58% and 67% of toxicity inhibition, respectively. Among three evaluated kinetic models (the first-order, the second-order, and Behnajady– Modirshahla–Ghanbary), experimental results fitted very well to the Behnajady - Modirshahla - Ghanbary model, indicating high initial rate of Black dye degradation.

The safety impact analysis of a widened corridor stretch of NH 66 was carried out in this study. A before and after black spot analysis was conducted using Arc Map 10.6 to identify significant hotspots using spatial joining and Getis Ord analysis. Two Poisson regression models were formulated for the weighted sum of fatal and grievous accidents for both pre lane widening as well as post lane widening conditions. The weighted sum of accidents showed a significant relationship with AADT value and black spot segment length in both models. It was found that 40-50 % reduction of crashes due to the lane conversion was estimated at a selected AADT range.

In the restoration of the historical and geographical conditions of today's Bulgarian lands, historical sources and documents of different origin, character and purpose come into use. The lack of sufficiently complete and accurate information about the development and dynamics of coastal archaeological landscapes in the narrative source material enhances the importance of medieval and renaissance maps of the Black Sea basin, which are an invaluable source of information. The combination of this information, together with the acquired archeological finds and the data from coastal and underwater geomorphological research, with great scientific reliability can restore the ancient appearance of certain objects. The study examined a large number of medieval and renaissance maps representing the port system on the Western Black Sea coast. The images of islands that do not exist today make a vivid impression. In order to be depicted on the navigational charts, it is obvious that they were important to the sailors of that time (hiding places, reef dangers, etc.). In the analysis of the old maps with the modern bathymetric map, as well as the conducted sea research, it was established that the locations of the depicted islands coincide with the places of modern rocky banks. The article offers options for their origin.

Originally introduced in the 1990s, bimodal HDPE, pipe resins are still finding new niches today, including even nuclear power plants. HDPE pipe grades are used to make strong, corrosion resistant and durable pipes. High density polyethylene, PE 4710, is the material of choice of the nuclear industry for the Safety Related Service Water System. This grade of polymer is characterized by a Hydrostatic Design Basis (HDB) of 1600 psi at 73 °F and 1000 psi at 140 °F. Additionally bimodal high density PE 4710 grades display >2000 hours slow crack growth resistance, or PENT. HD PE 4710 grades are easy to extrude into large diameter pipes; fabricate into fitting and mitered elbows and install in industrial settings. The scope of this paper is to describe the bimodal technology which produces HDPE pipe grade polymer; the USA practices of post reactor melt blending of natural resin compound with black masterbatch; and the attributes of such compound and its conformance to the nuclear industry’s Safety Related Service Water System.

Автор статьи рассматривает данное произведение» с точки зрения соотношения правды и художественного вымысла. Законы исторического документа требуют, как известно, однозначного соответствия факту, документу. Художественное произведение строится по другим законам - писатель имеет право трансформировать исторические события в соответствии со своим видением, идеей, включать художественный вымысел. Н. И.

The article is devoted to the analysis of the poem N. I. Rylenkova “Great Flinking”, written in 1940. It narrates about the uprising of the “black people” of Smolensk against representatives of the Grand Duke of Lithuania in the 15th century. The author of the article considers this work “ from the point of view of the ratio of truth and artistic fiction. The laws of a historical document require, as you know, unambiguous compliance with the fact, document. A work of art is built on other laws - the writer has the right to transform historical events in accordance with his vision, idea, and include artistic fiction. N. I. Rylenkov, turning to the distant history of Smolensk, preserving the key historical facts, complements the event with his thoughts and interpretation, ideas, reviving artistry, personifies the image of “black people” and introduces a modern theme for the 1940s.

The intensive development of remote sensing in the marine environment provides excellent bathymetric and substrate mapping opportunities on the southern Bulgarian Black Sea coast. The Bay of Chernomorets is a perfect opportunity to combine data from single-beam sonar, multi-beam sounding and drone imaging for the purpose of seabedforms and substrate mapping. This paper presents the second stages activity of the Project �Multidisciplinary study of Burgas Bay � MidBay. (Composition of a detailed digital model of the bottom relief with analysis of modern geomorphological conditions and archaeological forecasting modelling)� with a scientific goal of creating a substrate map and identification of seabed forms. The studied bay is strongly anthropogenically modified by the port in its southern part. In recent years, systematic studies of the landform changes have shown that the seabedforms, the beach and the shallowest part up to 2 meters in depth have changed. This is the main reason for choosing a solution that allows the 3D reconstruction of a coastal sector of Chernomorets. One of the purposes of the publication is to review the research through echo sounders and unmanned aerial systems along the Bulgarian Black Sea coast and analyse the methodology, equipment, and results obtained. The main task is to use good practices and successful methodology to combine echo-sounding and UAV surveys to derive a modern digital model of the terrain and raster data for the Bay of Chernomorets. Additionally, the process follows the good practices of using UAV and Sonar raster mosaic to detect borders between lithological varieties. The article aims to map seabed substrates in Folk 5 Classes and evaluate the accuracy of UAV-based DSMs, high-resolution orthomosaics and singlebeam echo sounding, which are fundamental for studying the most dynamic coastal landforms along the Bulgarian Black Sea coast.

Original objectives: Understanding the regulation of abscission competence by exploring the nature and function of auxin-related gene expression changes in the leaf and pedicelAZs of tomato (as a model system), was the main goal of the previously submitted proposal. We proposed to achieve this goal by using microarray GeneChip analysis, to identify potential target genes for functional analysis by virus-induced gene silencing (VIGS). To increase the potential of accomplishing the objectives of the previously submitted proposal, we were asked by BARD to show feasibility for the use of these two modern techniques in our abscission system. Thus, the following new objectives were outlined for the one-year feasibility study: 1.to demonstrate the feasibility of the VIGS system in tomato to perform functional analysis of known abscission-related genes; 2. to demonstrate that by using microarray analysis we can identify target genes for further VIGS functional analysis. Background to the topic: It is a generally accepted model that auxin flux through the abscission zone (AZ) prevents organ abscission by rendering the AZ insensitive to ethylene. However, the molecular mechanisms responsible for acquisition of abscission competence and the way in which the auxin gradient modulates it are still unknown. Understanding this basic stage of the abscission process may provide us with future tools to control abscission for agricultural applications. Based on our previous study, performed to investigate the molecular changes occurring in leaf and stem AZs of MirabillisJalapaL., we have expanded our research to tomato, using genomic approaches that include modern techniques for gene discovery and functional gene characterization. In our one-year feasibility study, the US team has established a useful system for VIGS in tomato, using vectors based on the tobacco rattle virus (TRV), a Lcreporter gene for silencing (involved in regulation of anthocyanin biosynthesis), and the gene of interest. In parallel, the Israeli team has used the newly released Affymetrix Tomato GeneChip to measure gene expression in AZ and non-AZ tissues at various time points after flower removal, when increased sensitivity to ethylene is acquired prior to abscission (at 0-8 h), and during pedicelabscission (at 14 h). In addition, gene expression was measured in the pedicel AZ pretreated with the ethylene action inhibitor, 1-methylcyclopropene (1-MCP) before flower removal, to block any direct effects of ethylene. Major conclusions, solutions and achievements: 1) The feasibility study unequivocally established that VIGS is an ideal tool for testing the function of genes with putative roles in abscission; 2) The newly released Affymetrix Tomato GeneChip was found to be an excellent tool to identify AZ genes possibly involved in regulation and execution of abscission. The VIGS-based study allowed us to show that TAPG, a polygalacturonase specifically associated with the tomato AZ, is a key enzyme in the abscission process. Using the newly released Affymetrix Tomato GeneChip we have identified potential abscission regulatory genes as well as new AZ-specific genes, the expression of which was modified after flower removal. These include: members of the Aux/IAAgene family, ethylene signal transduction-related genes, early and late expressed transcription factors, genes which encode post-translational regulators whose expression was modified specifically in the AZ, and many additional novel AZ-specific genes which were previously not associated with abscission. This microarray analysis allowed us to select an initial set of target genes for further functional analysis by VIGS. Implications: Our success in achieving the two objectives of this feasibility study provides us with a solid basis for further research outlined in the original proposal. This will significantly increase the probability of success of a full 3-year project. Additionally, our feasibility study yielded highly innovative results, as they represent the first direct demonstration of the functional involvement of a TAPG in abscission, and the first microarray analysis of the abscission process. Using these approaches we could identify a large number of genes involved in abscission regulation, initiation and execution, and in auxin-ethylene cross-talk, which are of great importance, and could enable their potential functional analysis by VIGS.

Objectives. To examine the evidence on whether and how healthcare algorithms (including algorithm-informed decision tools) exacerbate, perpetuate, or reduce racial and ethnic disparities in access to healthcare, quality of care, and health outcomes, and examine strategies that mitigate racial and ethnic bias in the development and use of algorithms. Data sources. We searched published and grey literature for relevant studies published between January 2011 and February 2023. Based on expert guidance, we determined that earlier articles are unlikely to reflect current algorithms. We also hand-searched reference lists of relevant studies and reviewed suggestions from experts and stakeholders. Review methods. Searches identified 11,500 unique records. Using predefined criteria and dual review, we screened and selected studies to assess one or both Key Questions (KQs): (1) the effect of algorithms on racial and ethnic disparities in health and healthcare outcomes and (2) the effect of strategies or approaches to mitigate racial and ethnic bias in the development, validation, dissemination, and implementation of algorithms. Outcomes of interest included access to healthcare, quality of care, and health outcomes. We assessed studies’ methodologic risk of bias (ROB) using the ROBINS-I tool and piloted an appraisal supplement to assess racial and ethnic equity-related ROB. We completed a narrative synthesis and cataloged study characteristics and outcome data. We also examined four Contextual Questions (CQs) designed to explore the context and capture insights on practical aspects of potential algorithmic bias. CQ 1 examines the problem’s scope within healthcare. CQ 2 describes recently emerging standards and guidance on how racial and ethnic bias can be prevented or mitigated during algorithm development and deployment. CQ 3 explores stakeholder awareness and perspectives about the interaction of algorithms and racial and ethnic disparities in health and healthcare. We addressed these CQs through supplemental literature reviews and conversations with experts and key stakeholders. For CQ 4, we conducted an in-depth analysis of a sample of six algorithms that have not been widely evaluated before in the published literature to better understand how their design and implementation might contribute to disparities. Results. Fifty-eight studies met inclusion criteria, of which three were included for both KQs. One study was a randomized controlled trial, and all others used cohort, pre-post, or modeling approaches. The studies included numerous types of clinical assessments: need for intensive care or high-risk care management; measurement of kidney or lung function; suitability for kidney or lung transplant; risk of cardiovascular disease, stroke, lung cancer, prostate cancer, postpartum depression, or opioid misuse; and warfarin dosing. We found evidence suggesting that algorithms may: (a) reduce disparities (i.e., revised Kidney Allocation System, prostate cancer screening tools); (b) perpetuate or exacerbate disparities (e.g., estimated glomerular filtration rate [eGFR] for kidney function measurement, cardiovascular disease risk assessments); and/or (c) have no effect on racial or ethnic disparities. Algorithms for which mitigation strategies were identified are included in KQ 2. We identified six types of strategies often used to mitigate the potential of algorithms to contribute to disparities: removing an input variable; replacing a variable; adding one or more variables; changing or diversifying the racial and ethnic composition of the patient population used to train or validate a model; creating separate algorithms or thresholds for different populations; and modifying the statistical or analytic techniques used by an algorithm. Most mitigation efforts improved proximal outcomes (e.g., algorithmic calibration) for targeted populations, but it is more challenging to infer or extrapolate effects on longer term outcomes, such as racial and ethnic disparities. The scope of racial and ethnic bias related to algorithms and their application is difficult to quantify, but it clearly extends across the spectrum of medicine. Regulatory, professional, and corporate stakeholders are undertaking numerous efforts to develop standards for algorithms, often emphasizing the need for transparency, accountability, and representativeness. Conclusions. Algorithms have been shown to potentially perpetuate, exacerbate, and sometimes reduce racial and ethnic disparities. Disparities were reduced when race and ethnicity were incorporated into an algorithm to intentionally tackle known racial and ethnic disparities in resource allocation (e.g., kidney transplant allocation) or disparities in care (e.g., prostate cancer screening that historically led to Black men receiving more low-yield biopsies). It is important to note that in such cases the rationale for using race and ethnicity was clearly delineated and did not conflate race and ethnicity with ancestry and/or genetic predisposition. However, when algorithms include race and ethnicity without clear rationale, they may perpetuate the incorrect notion that race is a biologic construct and contribute to disparities. Finally, some algorithms may reduce or perpetuate disparities without containing race and ethnicity as an input. Several modeling studies showed that applying algorithms out of context of original development (e.g., illness severity scores used for crisis standards of care) could perpetuate or exacerbate disparities. On the other hand, algorithms may also reduce disparities by standardizing care and reducing opportunities for implicit bias (e.g., Lung Allocation Score for lung transplantation). Several mitigation strategies have been shown to potentially reduce the contribution of algorithms to racial and ethnic disparities. Results of mitigation efforts are highly context specific, relating to unique combinations of algorithm, clinical condition, population, setting, and outcomes. Important future steps include increasing transparency in algorithm development and implementation, increasing diversity of research and leadership teams, engaging diverse patient and community groups in the development to implementation lifecycle, promoting stakeholder awareness (including patients) of potential algorithmic risk, and investing in further research to assess the real-world effect of algorithms on racial and ethnic disparities before widespread implementation.

Climate change, conflict, and the COVID-19 pandemic and its aftermath have caused a sharp increase in food insecurity globally. Reducing food loss - a decrease in the quantity and/or quality of food that takes place from production through to processing - in places where food insecurity is most severe has the potential to be a win-win for food security, climate outcomes, and for commercially driven agribusinesses. This report reviews the common drivers of food loss in sub-Saharan Africa and South Asia, which include inadequate storage, lack of cold chain, and poor post-harvest and distribution practices. It then highlights five technologies or approaches which have the potential to address food loss, and which are appropriate for agricultural small and medium-sized enterprises (agri-SMEs) operating in much of sub-Saharan Africa and South Asia, which face particular challenges (e.g. an unreliable electrical grid and fragmented value chains). Finally, the report highlights the main barriers to adoption and scale for these technologies and approaches, and identifies opportunities for governments, development partners, investors, and technology manufacturers to improve their uptake among agri-SMEs. The five technologies and approaches covered in this report are as follows: Decentralization of processing using solar dryers: The decentralization of primary food processing, in which some portion of value addition is undertaken close to the farm gate by farmers or SMEs, can have multiple benefits, including reducing food loss, lowering transport costs, and increasing rural incomes. Solar drying technology can enable this model, particularly in areas where there is a tradition of sun drying fruits and vegetables and there is a viable domestic or regional market for these products. Successful models typically involve an agribusiness off-taker who works with farmers and SME producers, providing technology and services (e.g., guaranteed off-take, training etc.) that ensure the production of high-quality produce. Hermetic storage (e.g. bags and cocoons): This maturing technology is increasingly available in local markets and represents a potentially easy-to-implement solution which could help to substantially address food loss during storage - where most loss occurs - for key staple grains. Cost and usage remain challenges for smallholders, with greater potential for small- to medium-scale traders and aggregators in rural areas with limited storage infrastructure. By creating a hypoxic environment around the produce, these solutions can achieve 100% insect mortality and reduce the growth of mould and aflatoxins. Bags are more appropriate for agri-SMEs involved in distribution, whereas cocoons (i.e. storage containers consisting of two plastic halves joined together by an airtight zip) are more useful for those storing large volumes for periods of six months or longer. Off-grid cold storage (e.g. solar-powered cold rooms): Innovative technologies and delivery mechanisms are still being tested in markets in India, Nigeria, and Kenya. Despite the high upfront cost, there are several examples of agri-SMEs and co-operatives achieving payback periods of as little as two years across a range of fruit and vegetable value chains, with returns driven by reductions in food loss and improved pricing due to better quality of the produce. Cooling as a service business models also offer the potential to reach smaller agri-SMEs and micro-entrepreneurs operating in informal rural and peri-urban value chains, but their application is limited to high-value crops that are generally out of the reach of the rural poor. Agri-ecommerce platforms: Agri-ecommerce platforms are a well-developed technology that aims to reduce food loss by improving the availability of information on market demand for farmers. Technology providers can also engage in logistics, warehousing, and quality control, taking collection of the produce from rural-based hubs, combining it at a central packing house, and delivering to urban retailers. Models of this kind have scaled more effectively in South Asia than sub-Saharan Africa, where they are constrained by poor road and logistics infrastructure. Waste-to-value approaches: Waste-to-value or circular economy approaches have the potential to reduce food loss by utilizing bruised or damaged fruits and vegetables which are unable to be sold as intended as inputs into other food products. Although the application of these approaches to the production of products such as condiments and oils is popular, they are unlikely to have a material impact on food security. However, models such as using black soldier fly larvae (BSFL) to produce animal feed (after consuming the food waste) are more promising, with a range of related technologies and business models operating in markets in both Africa and Asia. The main barriers to the success and scaling up of these technologies and approaches include a lack of knowledge and awareness of their commercial benefits, a lack of finance for manufacturers and agri-SME customers, a need for further research and development (R&D) and business model innovation (e.g. to bring down cost), and a lack of supportive policies and regulatory frameworks. Policymakers, development partners, investors, and the private sector can all play important roles in addressing these barriers.
