General Relativity Is the Wrong Theory
Authors:   China Aerospace Science and Technology Corporation, P. O. Box 142-206, Beijing 100854, P. R. China, Jiang Chun-Xuan
Published: July 2021

Using space-time ring we establish the mathematical theory of space-time with subluminal and superluminal coexistence(SASC) and ILS [1]. Using two methods we deduce the new gravitational formula. Tardyonic rotating motion produces the centrifugal force ,but tachyonic rotating motion produces the centripetal force, that is gravity. Using it we establish the expansion theory of the universe and suggest the new universe model. We prove that in the universe there are no dark matter and no dark energy. New gravitational formula changes all that. Multiverse and gravitational waves do not exist. Theory of everything has the two forces: (1) the subluminal force (electromagnetism and weak force) and (2) superluminal force(gravity and strong force).We prove that equivalence principle does not exist.Therefore we prove that general relativity is the biggest wrong theory [2]

O canto vinha de longe, de lá do meio do mar: trajetos de putas transexuais na escola e no trabalho
Authors: Ercoles Clara Hanke , Maio Eliane Rose
Published: July 2021

Quem conhece a lenda das sereias talvez ainda não tenha escutado a da sereia travesti, nem em casa, nem na escola, nem em algum lugar. Afinal, travestis e mulheres transexuais são violentadas em nossa sociedade. A maioria das instituições sociais, como a escola, e o mercado de trabalho formal não aceitam suas estilísticas de existência e as marginalizam, expulsando-as de seus espaços. Elas resistem, buscando sobrevivência e autonomia por meio da prostituição. Se um dos objetivos da educação escolar é formar para o trabalho, como foi a formação das travestis e mulheres transexuais putas? Por meio da Cartografia, mapeamos o trajeto escolar e profissional de duas mulheres transexuais, de duas cidades do interior do Paraná, usando suas entrevistas com o objetivo de compreender a expulsão que elas sofrem dos espaços formais de educação e de profissão. Através da partilha de suas histórias, percebemos que a expulsão acontece de fato e que isso não as imobiliza, mas faz com que resistam.

Introduction. Aluminium production is characterized by the accumulation of impurities of various toxic and chemical compositions in the air of working areas, the predominant among which are fluoride compounds. The accumulation of fluorides in the body causes the development of osteoarticular and associated systemic pathology. The aim of the study was to evaluate the hygienic and medico-biological features of toxic liver damage in the conditions of chronic fluoride intoxication of the body. Material and methods. The hygienic working conditions of the workers of the primary professions in aluminium production were evaluated. The analysis of hepatobiliary dysfunction based on clinical and instrumental methods was carried out in 263 subjects with fluoride intoxication and a comparison group of 116 persons. Experimental studies of the morpho-functional liver state in modelling chronic fluoride intoxication were carried out based on toxicological, biochemical, pathomorphological methods with histological analysis of tissues. The toxic properties of sodium fluoride were studied in 117 white laboratory male rats with its peroral route intake into the body. Results. The qualitative composition of the air in the working areas in the electrolysis building was analyzed. The prevalence of pathological disorders of the biliary tract in metallurgists engaged in aluminium production was assessed. Clinical studies revealed a significant prevalence of toxic fluoride hepatopathy, fatty hepatosis, cholecystitis and other disorders in the group of patients with chronic fluoride intoxication. The harmful effect of sodium fluoride on hepatocytes, vessels of the portal tract was shown in an experiment. Hyperfunction of the reticuloendothelial system, Kupffer cell proliferation, irreversible destruction of hepatocytes, necrosis against the background of severe dystrophy, and decreased synthetic activity of the liver were determined. Conclusion. The structure of occupational diseases in the workers engaged in the aluminium production is dominated by hepatobiliary pathology caused by toxic liver damage with fluoride confirmed by experimental data on destructive violations of its morphostructure.

Introduction. Occupational air is contaminated with zinc oxide nanoparticles in the copper smelting industry, especially in the smelting of brass and copper. A wide range of toxic effects with varied clinical symptomatology is observed in zinc and its compounds. Competitive relations with many other metals, including calcium, copper, and iron, are the foundation of most cases of zinc intoxication. Long-term administration of zinc or its compounds to laboratory rodents affects enzymes, carbohydrates and mineral metabolism. Materials and methods. Subchronic intoxication with repeated intraperitoneal injections and acute low respiratory tract reaction to a single intratracheal injection of zinc nanoparticles were simulated in outbred white rats. Water suspensions of zinc oxide nanoparticles with a 30-80 nm diameter were applied in both experimental models. Upon completion of the exposure, the condition of the rats in all groups was evaluated in many generally accepted criteria for toxicity. The student’s t-test was applied for statistical analysis of the obtained data. Results. Moderate intoxication development in a subchronic experiment is demonstrated. Homogeneous ultrastructural changes in the spleen tissue were revealed. Mitochondrial damage with partial or complete loss of crista is the most common. The fragmentation ratio of DNA was found by a statistically significant increase. A single intratracheal injection of zinc oxide nanoparticles revealed the increase in the attraction of cells capable of their phagocytosis (mainly neutrophils) into the low respiratory tract. This shows their cytotoxicity. Conclusion. Moderate general toxic and cytotoxic effects of zinc oxide nanoparticles on the rat body were identified.

The purpose of the study was a comparative assessment of the actual diet of preschoolers, taking into account changes in the requirements of sanitary legislation on the organization of public catering. Materials and methods. Nutrition was assessed based on a study of the menu-layouts of two-week implemented menus in 4 preschool organizations. The analysis of children’s diets’ nutritional and biological value was carried out according to the leading indices of normative documents and legislative acts. A comparative characteristic of the actual food set was carried out, taking into account the changes in the requirements, the sanitary and epidemiological rules, and norms of SanPiN 2.3 / 2.4.3590-20 that had come into effect again. Results. The structure of the food set sold to children in the preschool organization was irrational. The optimal consumption (from 94 to 104% of the norm) of primary food products (meat, poultry, milk and dairy products, cottage cheese, sour cream, eggs) was established. The disadvantage of the menus under analysis was the deficit in the food assortment of rye bread, fish, fruit, leftover pasta, sugar, confectionery, and the presence of products excluded from the new food set (sausages). The nutritional and energy value of children’s diets was sufficient compared to the norms of physiological needs. However, there was an imbalance in both macro and micronutrients, especially calcium, phosphorus, and magnesium. Conclusion. According to the menu-layouts in children’s institutions, evaluation of children’s nutrition showed that they did not comply with both the previously existing and newly introduced regulatory requirements for indices of food supply and the chemical composition of rations. The needs of the recently entered sanitary rules and norms for feeding organizations were not considered when drawing up the menu in institutions. Revision of the food set requires making adjustments to the technological charts for baby nutrition and the elaboration of guidelines for developing menus in new conditions.

Published: July 2021

One of the main objectives of sustainable development is to improve living standards and obtain a friendlier business environment, by increasing their competitiveness and performance and the main goal of companies are to achieve a productive activity that ensures their short-term success, but also to pay attention to long-term survival. This analysis was performed to assess the influence of financial indicators of companies and their contribution on the sustainable development of the North-West region of Romania. The research follows the evolution of sustainable development and financial indicators of the sample of 37 companies listed on the BSE, with data collected from 2008-2019, covering the following sectors according to their BSE classification: manufacturing, trade, hotels, construction. In this paper is used both qualitative and quantitative research methods. Among the qualitative research methods used it can be mentioned: observation, comparison and analysis of data. The econometric analysis is based on the estimation of a panel data regression technique and the decision between the random effects model and the fixed effects model was based on the Hausman test. The microeconomic indicators used to analyse the connection with the indicators of sustainable development of the North-West region of Romania are turnover, net profit and the average number of employees used as independent variables and the indicators selected based on information provided by the National Institute of Statistics for the North-West region, called Territorial Sustainable Development Indicators, are the following: Regional Gross Domestic Product, GDP per inhabitant, economically active population, the employment rate of the working age population, the job vacancy rate and the unemployment rate used as dependent variables. The results of the correlation analysis of the parameters showed a weak, insignificant influence between the financial indicators and the sustainable development indicators, the observed data do not allow the identification of a valid linear model.

Atrial fibrillation and non-vitamin K antagonist oral anticoagulants: from clinical trials to real-world clinical practice.

For decades, vitamin K antagonists (VKAs) were the only oral anticoagulants available for the prevention of thromboembolism in patients with atrial fibrillation (AF). Since 2012, non-vitamin K antagonist oral anticoagulants (NOACs) are available for this indication, which have proven to be at least as effective and safe as VKAs in randomized controlled trials (RCTs). NOACs have additional benefits, such as a fast onset of action, a fixed-dose regimen without requiring regular monitoring, less interactions and less intracranial bleeding. Their emergence has caused a paradigm shift in anticoagulation therapy, with NOACs being the anticoagulant of choice compared to VKAs. Since strict in- and exclusion criteria were used in the pivotal RCTs, concerns have risen regarding the generalizability of these results to real-life clinical practice in patients with multiple comorbidities. In this manuscript, this extrapolation is discussed, focusing on 4 different topics regarding appropriate NOAC use: the management of AF patients with a single stroke risk factor, the importance of an optimal therapy adherence, potential drug-drug interactions with NOACs and addressing a geriatric AF patient after a fall. Hopefully, this manuscript will help guide clinicians in the optimal use of NOACs in their daily clinical practice.
The Real Is Radical
Authors: Fardy Jonathan
Published: July 2021

The Real is Radical is centrally concerned with the explication and development of François Laruelle’s theory of “non-standard Marxism.” Fardy assembles a constellation of concepts designed to put Laruelle’s work into dialogue with diverse theoretical perspectives, including Althusser, Tronti, Adorno, Baudrillard, Kolozova and others while demonstrating the novelty and theoretical saliency of Laruelle’s work. The Real is Radical provides a much-needed introduction to non-standard Marxism and a useful starting point for the development of its theoretical potential.
Education in Radical Uncertainty
Authors: Carney Stephen , Ambrosius Madsen Ulla
Published: July 2021

In Education in Radical Uncertainty, Stephen Carney and Ulla Ambrosius Madsen return to the philosophical and social critique of Jean Baudrillard and relate his work to the field of education, particularly to comparative studies of youth and schooling in different parts of the world. The book explores how the initial interest in Baudrillard’s work has been replaced by skepticism, and how the field of educational studies has been complicit in marginalizing his influence. The authors argue that labelling Baudrillard as the most extreme of the post-modernists is both misguided and unfortunate, denying a generation of education researchers an engagement with insights that are both profound and challenging. They do so by exploring three of his key ideas: simulation leading to spectacle and seduction; integral reality leading to disappearance; and evil, reversibility and return.

The authors situate Baudrillard's works in the broader context of works by other post-foundational theorists, such as Michel Foucault and Gilles Deleuze, as well as exploring them in relation to empirical studies. Considering ethnographic work with youth in three quite different contexts - Denmark, South Korea and Zambia – the authors use a range of data to bring the different field studies alive and to contrast them with conventional portraits of the Global South. Encompassing both theoretical and methodological innovation, Education in Radical Uncertainty provides inspiration for scholars and students attempting to approach fields of comparative education and youth studies anew
Cesare Zavattini’s Neo-realism and the Afterlife of an Idea
Authors: Brancaleone David
Published: July 2021

How many Zavattinis are there? During a life spanning most of the twentieth century, the screenwriter who wrote Sciuscià, Bicycle Thieves, Miracle in Milan, and Umberto D. was also a pioneering magazine publisher in 1930s Milan, a public intellectual, a theorist, a tireless campaigner for change within the film industry, a man of letters, a painter and a poet. This intellectual biography is built on the premise that in order to understand Zavattini’s idea of cinema and his legacy of ethical and political cinema (including guerrilla cinema), we must also tease out the multi-faceted strands of his interventions and their interplay over time. The book is for general readers, students and film historians, and anyone with an interest in cinema and its fate.
Sam Cooke’s Live at the Harlem Square Club, 1963
Authors: Fleming Colin
Published: July 2021

Shelved for over 20 years, Sam Cooke’s Live at the Harlem Square Club, 1963, stands alongside Otis Redding’s Live in Europe and James Brown’s Live at the Apollo as one of the finest live soul albums ever made. It also reveals a musical, spiritual, emotional, and social journey played out over one night on the stage of a sweaty Miami club, as Cooke made music that encapsulated everything he had ever cut, channeling forces that would soon birth “A Change is Gonna Come,” the most important soul song ever written.

This book covers Cooke’s days with the Soul Stirrers, the gospel unit that was inventing a strand of soul in the 1950s, and continues on to his string of hit singles as a solo artist that reveal far more about this complex man and the complex music he was always fashioning. A writer and an agent of social change, he absorbed the teachings of Billie Holiday and Bob Dylan while reconciling his own identity and what fans expected of him. Fleming explores how this towering soul artist came to reconcile so many disparate elements on a Florida stage on a winter night in 1963—a stage that extended well into the future, beyond Cooke’s own life, beyond the 1960s, and into a perpetual here-and-now. Live at the Harlem Square Club, 1963 will resonate so long as we all have need to look into ourselves and square our differences and become more human, and more connected with others in our humanity.

Trouble in Paradise
Authors: Weir David
Published: July 2021

Ernst Lubitsch’s Trouble in Paradise (1932) was released at a critical moment in cinema history, just after the advent of synchronized sound technology and just before the full implementation of the production code. By the time of its release, Lubitsch had already directed more than 50 films, but it was unlike anything he had done before. Aside from being his first non-musical talking picture, the film introduced a level of sophistication and visual subtlety that established the benchmark for classic Hollywood cinema for years to come.

In his study of the film, David Weir explores its significance within Lubitsch’s career, but also its larger cultural significance within the history of cinema, and the social context of its release during the Great Depression. Paying careful attention to the film itself, Weir discusses its source material, its mise-en-scène and art deco production design, and its inventive use of post-synchronized sound. Drawing on original archival research, Weir traces Trouble in Paradise's reception history, including its critical reception, and the effect of the Motion Picture Production Code, which led to the film being denied approval for re-release in 1935.
Trainspotting
Authors: Smith Murray
Published: July 2021

In 1996 Trainspotting was the biggest thing in British culture. Brilliantly and aggressively marketed, it crossed into the mainstream despite being a black comedy set against the backdrop of heroin addiction in Edinburgh. Produced by Andrew Macdonald, scripted by John Hodge and directed by Danny Boyle, the team behind Shallow Grave (1994), Trainspotting was an adaptation of Irvine Welsh's barbed novel of the same title. The film is crucial for understanding British culture in the context of devolution and the rise of ‘Cool Britannia’.

Murray Smith unpicks the processes that led to Trainspotting's enormous success. He isolates various factors – the film's eclectic soundtrack, its depiction of Scottish identity, its attitude to deprivation, drugs and violence, its traffic with American cultural forms, its synthesis of realist and fantastic elements, and its complicated relationship to ‘heritage’ – that make Trainspotting such a vivid document of its time. Although it heralded a false dawn for British film-making,Trainspotting is, Smith concludes, both authentically vernacular and yet transnational in its influences and ambitions.

In his afterword to this new edition, Murray Smith reflects on the original film 25 years after its release, and its 2017 sequel T2: Trainspotting also directed by Boyle. Smith also considers Danny Boyle's subsequent directorial career, with highlights including Slumdog Millionaire (2008) and the 2012 London Olympics opening ceremony.
The Thing
Authors: Billson Anne
Published: July 2021

An extra-terrestrial alien, capable of replicating any living form it touches, infiltrates an isolated research base in the Antarctic, and sows suspicion and terror among the men trapped there. Which of them is still human, and which a perfect alien facsimile? John Carpenter’s The Thing, the second adaptation of John W. Campbell’s 1938 novella Who Goes There?, received overwhelmingly negative reviews on its release in 1982, but has since been acknowledged as a classic fusion of the science fiction and horror genres. Now a regular fixture in lists of the greatest movies of all time, it is acclaimed for its inspired and still shocking practical special effects, its deftly sketched characters brought to life by a superb cast, elegant widescreen cinematography, ominous score, and a uniquely tense narrative packed with appropriately ever-changing metaphors about the human condition.

Anne Billson’s elegant and trenchant study, first published in 1997, was one of the first publications to give the film its due as a modern classic, hailing it as a landmark movie that brilliantly redefined horror and science fiction conventions, and combined them with sly humour, Lewis Carroll logic and disturbingly prescient metaphors for many of the sociopolitical, scientific and medical upheavals of the past three decades.

In her foreword to this new edition, Anne Billson reflects upon The Thing's changing fortunes in the years since its release, its influence on film-makers including Tarantino and del Toro, and its topicality in an era of melting ice caps and with humanity besieged by a deadly organism.
The Silence of the Lambs
Authors: Tasker Yvonne
Published: July 2021

Released in 1990, The Silence of the Lambs is one of the defining films of late twentieth century American cinema. Adapted from the Thomas Harris novel and directed by the late Jonathan Demme, its central characters are now iconic. Jodie Foster is Clarice Starling, an FBI trainee investigating ‘Buffalo Bill’, a serial killer who flays his victims. Anthony Hopkins plays Hannibal Lecter, a serial killer and former psychiatrist who assists Starling in exchange for personal details.

With its pairing of a perverse, invasive anti-hero and a questing, proto-action heroine, The Silence of the Lambs unfolds as a layered narrative of pursuit. In this study, Yvonne Tasker explores the film’s weaving together of gothic, horror and thriller elements in its portrayal of insanity and crime, drawing out the centrality of ideas about gender to the storytelling. She identifies the film as a key genre reference point for tracking late twentieth century interests in police procedural, profiling and serial murder, analysing its key themes of reason and madness, identity and belonging, aspiration and transformation.

A new afterword explores the legacies of The Silence of the Lambs and its figuring of crime and investigation in terms of gender disruption and spectacular violence.

Recognising one’s identity to enter a system is called authentication. This process can take various forms where users input the system with a set of identifying credentials to access the system. Signatures belong to behavioural biometric, where the distinct features of every individual are considered in order to corroborate the person’s identity. The act of falsely imitating one’s signature biometric to impersonate and leverage access to their asset is called signature forgery. Our paper presents a comparative study of various deep learning models using Siamese architecture, over a wide catalogue of signature images. Openly available datasets like CEDAR, Handwritten Signatures dataset from Kaggle, ICDAR 2011 SigComp, and BH-Sig260 signature corpus are used to train the models. A set of classifiers – Support Vector Classifiers (SVC), Gaussian Naïve Bayes (GNB), Logistic Regression (LR) and K-Nearest Neighbours (KNN) are applied sequentially to classify the signature as genuine or forged.

Research on real-time elimination of ultra-wideband radar ranging abnormal value data
Authors: Yan Xin , Liu Hui , Xin Guoxuan , Huang Hanbo , Jiang Yuxi , Guo Ziye
Published: July 2021

Abstract. For indoor positioning, ultra-wideband (UWB) radar comes
to the forefront due to its strong penetration, anti-jamming, and high-precision ranging abilities. However, due to the complex indoor environment
and disorder of obstacles, the problems of diffraction, penetration, and
ranging instability caused by UWB radar signals also emerge, which make it
difficult to predict the noise and leads to a great impact on the accuracy
and stability of the measurement data in the short term. Therefore, the
abnormal value migration of the positioning trajectory occurred in real-time
positioning. To eliminate this phenomenon and provide more accurate results,
the abnormal values need to be removed. It is not difficult to eliminate
abnormal values accurately based on a large number of data, but it is still a
difficult problem to ensure the stability of the positioning system by using
a small number of measurement data in a short time to eliminate abnormal
value in real-time ranging data. Thus, this paper focuses on the
experimental analysis of a UWB-based indoor positioning system. By
repeatedly measuring the range , a large number of measurement data can be
obtained. Using the massive data to train linear regression models, we get
the parameter of the linear model of range data measured with the UWB radar.
Based on the Gaussian function outlier detection, abnormal values are
eliminated, and putting the new range data into the regression model trained
by us, the ranging error is reduced by nearly 50 % compared with the peak
and mean ranging errors in general.

Gagal jantung merupakan masalah kesehatan yang progresif dengan angka mortalitas dan morbiditas yang tinggi di negara maju maupun negara berkembang termasuk Indonesia. Pada tahun 2016, WHO menyebutkan 17,5 juta orang meninggal akibat penyakit kardiovaskular sedangkan pada tahun 2008, penyakit ini mewakili dari 31% kematian di dunia. Perkiraan akurat dari prognosis gagal jantung sangat penting bagi layanan kesehatan untuk memungkinkan alokasi sumber daya yang tepat kepada dokter dalam membuat keputusan untuk manajemen dan kepada pasien untuk memungkinkan pilihan informasi tentang perawatan dan perawatan akhir kehidupan. Sehingga pada penelitian kali ini dilakukan penerapan metode optimasi Particle Swarm Optimization (PSO) pada algoritma Naïve Bayes sebagai seleksi fitur, yang bertujuan untuk mengetahui nilai akurasi yang dihasilkan oleh algoritma Naïve Bayes dan peran optimasi PSO untuk meningkatkan nilai akurasi dari hasil prediksi harapan hidup pasien gagal jantung. Setelah dilakukan pengujian menggunakan aplikasi Rapidminer dapat diketahui bahwa hasil klasifikasi menggunakan optimasi metode PSO yang mendukung metode  Naive Bayes dapat menghasilkan nilai akurasi yang lebih baik, yaitu sebesar 92.67% dan nilai Area Under ROC (AUC) sebesar 0.908. Hasil akurasi yang didapat pada penelitian kali ini termasuk kedalam kategori Excellent Classification.
