On Ultra-Reliable Low Latency Multipath TCP For Connected Autonomous Vehicles
Authors: Pokhrel Shiva Raj , Kumar Neeraj , Walid Anwar
Published: July 2021

Connected Autonomous Vehicles (CAVs) are Not-So-Futuristic. CAVs will be highly dynamic by intelligently exploiting multipath communication over several radio technologies, such as high-speed WiFi and 5G and beyond networks. Yet, the likelihood of data communication loss can be very high and/, or packets arrive at the destination not in correct working order due to erratic and mixed time-varying wireless links. Furthermore, the vehicular data traffic is susceptible to loss and delay variation,which recommends the need to investigate new multipath TCP(MPTCP) protocols for ultra-reliable low latency communication(URLLC) over such heterogeneous networks while reassuring CAVs’ needs. We undertake the challenge by jointly considering network coding and balanced linked adaptation for performing coupled congestion control across multiple wireless paths.Consequently, the proposed low delay MPTCP framework for connecting autonomous vehicles is efficient and intelligent by design. We conduct a rigorous convergence analysis of the MPTCP design framework. In summation, we provide a detailed mathematical study and demonstrate that the latency penalty for the URLLC-MPTCP developed over these networks becomes negligible when considering the possible benefits that multiple network convergence could offer. Our extensive emulation results demonstrate all these lucrative features of URLLC-MPTCP.

Norms and Novelty: Reflections on Legal Knowledge, Norms and Evolutionary Systems
Authors: Tuzet Giovanni
Published: July 2021

The paper has three sub-topics: legal knowledge, legal norms, and evolutionary systems. The three are interconnected. A reflection on the nature of legal knowledge throws light on the nature of legal norms. Legal knowledge is largely a posteriori and it is so because norms are largely contingent. Being a realm of continual change, law has novelty as a fundamental feature. The process of legal change is not driven by chance but by the attempt to face ever new problems and changing circumstances. This supports a view of legal systems as adaptive and evolutionary, as classical pragmatism suggested. However, inference can give some a priori legal knowledge.

Trabalhadores rurais e migração na Califórnia dos anos 30: John Steinbeck e os "Ciganos da colheita"
Authors: Berno Kölln Lucas André
Published: July 2021

No verão de 1936, o romancista John Steinbeck viajou a soldo do jornal The San Francisco News para cobrir o fenômeno dos migrantes que se apinhavam pelas estradas da Califórnia e dos Estados Unidos no rescaldo dos dust bowls e da crise de 1929. Como resultado da viagem, Steinbeck escreveu sete artigos que foram publicados em outubro de 1936 e batizados de "Os ciganos da colheita". Esses textos têm grande valor documental sobre os efeitos sociais da recessão econômica e, esse é nosso argumento, participaram de maneira fundamental da mudança de perspectiva da literatura de Steinbeck, tornando-a mais politicamente engajada e esteticamente realista. O propósito desse artigo é entender como a experiência do verão de 1936 alterou a percepção crítica de Steinbeck acerca da realidade estadunidense, entendendo que os migrantes foram fundamentais nesse processo, visto que explicitaram o parentesco histórico entre os trabalhadores e as antigas classes médias rurais às quais o escritor pertencia. Essa descoberta realçou o clamor democrático de sua literatura, o qual culminou no maior romance sobre a Grande Depressão: As vinhas da ira de 1939.
Ideais salazaristas no Brasil: imigrantes portugueses em Florianópolis e as redes de sociabilidade em torno na Revista Luso-brasileira na década de 1960
Authors: Iuskow Cristina
Published: July 2021

Este artigo tem como objetivo tratar dos migrantes portugueses em Florianópolis na década de 1960, provindos de Portugal que vivia a época sob o regime do Estado Novo de Antonio Salazar.  Nesse contexto surgiu em Florianópolis a Revista Luso-Brasileira, fundada pelo português migrante Mario Fernandes Dias, a qual circulou entre 1961 e 1979. Periódico de variedades com 20 páginas e uma tiragem de 1000 exemplares por edição, mensal e bimestral. Seus mil exemplares eram expedidos para Portugal, Angola, Cabo Verde e outras cidades do Brasil. Nesse artigo tratarei de compreender de que forma a revista se relacionava com portugueses emigrados, quais matérias eram direcionadas a eles e qual teor político ligado ao salazarismo era veiculado pelo periódico. Ainda busco contemplar neste trabalho as maneiras pelas quais portugueses migrantes criavam redes de sociabilidades em torno da revista e do seu próprio grupo. Palavras-chave: Relações luso-brasileiras, Migração, Impressos, Salazarismo.
“Deslocados da seca" na Hospedaria Getúlio Vargas: experiências e trajetórias de migração para diversas paragens (Ceará, década de 1950)
Authors: Monteiro Renata Felipe
Published: July 2021

A trajetória dos migrantes na Hospedaria Getúlio Vargas (Fortaleza, Ceará) teve início na década de 1940, quando diversos acordos foram concretizados entre Brasil e EUA no contexto da Segunda Guerra Mundial para a extração da borracha na Amazônia. Assim, foram construídos pousos e hospedarias nas regiões Norte e Nordeste, que seriam responsáveis por abrigar e encaminhar os trabalhadores nordestinos para o trabalho na região amazônica. A partir da década de 1950, a Hospedaria Getúlio Vargas tornou-se o principal centro de referência para a população migrante cearense, que almejava ir para outras regiões do país. Baseado em uma variedade de fontes (jornais, entrevistas, dentre outros), objetivamos entender a trajetória de alguns trabalhadores nordestinos que passaram pela Hospedaria Getúlio Vargas na década de 1950.

As participações indígenas nas guerras no Cabo do Norte
Authors: Nascimento Bruno Rafael Machado
Published: July 2021

Este artigo tem objetivo de desvelar as agências indígenas nos conflitos entre portugueses, holandeses, ingleses e irlandeses pela conquista do Cabo do Norte (parte do atual Estado do Amapá) na primeira metade do século XVII. A partir da leitura histórica e antropológica das fontes, percebeu-se como os ameríndios criaram táticas de sobrevivência em contextos desfavoráveis, e como os europeus foram dependentes dessas sociedades que conheciam muito bem a Amazônia, sobretudo, nas guerras por controle do território. Demonstra-se como as alianças com as populações nativas e os usos de seus guerreiros em combates foram decisivas para as vitórias ou derrotas dos colonizadores.

O presente artigo discute a presença de homens considerados “de cor” nas forças armadas no início do período imperial brasileiro, a partir do caso da província de Santa Catarina. As categorias utilizadas para definir a cor dos sujeitos e classificá-los por hierarquias sociais eram relevantes quando se pensava a criação e manutenção de corpos militares. Argumenta-se que as forças armadas, e os períodos de conflito, em especial, aumentavam as possibilidades para que libertos ou escravos buscassem ampliar seu grau de liberdade. Partindo dos parâmetros da Nova História Militar, utiliza-se documentação trocada entre as autoridades responsáveis por pensar o recrutamento.

Objective: For 2019 and 2020, SARS-CoV-2 has been a sensational virus. Unfortunately, a treatment agent specific for SARS-CoV-2 has not been developed yet. Favipiravir is one of the antiviral agents used experimentally in the treatment of SARS-CoV-2. This study aimed to determine the frequency of side effects seen in patients hospitalized in our hospital and received favipiravir at any stage of their treatment.

Methods: Our study is a retrospective observational study. Definite and probable COVID-19 cases hospitalized in our hospital between March 23, 2020, May 31, 2020, were determined, and those receiving favipiravir as initial or secondary therapy were included in the study. The demographic data, laboratory tests, observed side effects of the patients were recorded and analyzed statistically.

Results: A total of 134 patients, 37.3% using favipiravir at the beginning and 62.7% as secondary, were included in the study. The mean age of the patients was 66.8±15.7 years. 38.1% (n=51) of the group were female. Side effects were detected in 17 (13%) patients in the whole group. Hepatotoxicity (4.5%), increased serum uric acid (4.5%), nephrotoxicity (1.5%), gastrointestinal side effects (1.5%), cardiac side effects (0.7%) were detected. There was no statistically significant difference in terms of adverse events between the patients who received favipiravir initially or later on disease course.

Conclusions: Although some results support the short-term safety of favipiravir, more studies are needed for its long-term effects. Studies on hyperuricemia, QTc prolongation, use in pregnancy, use during lactation and use in children are insufficient. Therefore, although Favipiravir appears to be a good alternative in the treatment of COVID-19, it should be used carefully because the data on its safety is still insufficient.

Key Words: Favipiravir, adverse effects, COVID-19, SARS-CoV-2

The demand for high-speed boats that operating near to shoreline is increasing nowadays. Understanding the behavior and attitude of high speed boats when moving in different waterways is very important for boat designer. This research uses a CFD (Computational Fluid Dynamics) analysisto investigate the shallow water effects on prismatic planing hull. The turbulence fl ow around the hull was described by Reynolds Navier Stokes equations RANSE using the k-ɛ turbulence model. The free surface was modelled by the volume of fl uid (VOF) method. The analysis is steady for all the ranges of speeds except those close to the critical speed range Fh=0.84 to 1.27 due to the propagation of the planing hull solitary waves at this range. In this study, the planing hull lift force, total resistance, and wave pattern for the range of subcritical speeds, critical speeds, and supercritical speeds have been calculated using CFD. The numerical results have been compared with experimental results. The dynamic pressure distribution on the planing hull and its wave pattern at critical speed in shallow water were compared with those in deep water. The numerical results give a good agreement with the experimental results whereas total average error equals 7% for numerical lift force, and 8% for numerical total resistance. The worst effect on the planing hull in shallow channels occurs at the critical speed range, where solitary wave formulates.

Высокопрочные стали с пределом прочности 800–1100 МПа в последние годы стали предметом исследования как предприятий, их использующих, так и научных учреждений, которые изучают их свойства в технологических процессах листовой штамповки. Эти стали наряду с высокой прочностью, отвечают требованиям высокого уровня пластичности, технологичности при выполнении сборочных операций и др. требованиям.

Высокая прочность и значительное деформационное упрочнение приводят к отклонению размеров штампованных деталей по сравнению с размерами заданными инструментом. Это следствие действия упругих напряжений, которые неравномерно распределены по толщине заготовки после снятия деформирующей нагрузки, Такое пружинение характерно для деталей в форме прямолинейного или изогнутого жёлоба; в виде открытого сложного профиля и др. похожих деталей. Пружинение отсутствует полностью или очень незначительное у деталей в форме тела вращения или коробчатой формы с замкнутым контуром и фланцем или без него.

Процесс импульсной электрогидравлической (ЭГ) калибровки деталей является наиболее эффективным для устранения пружинения деталей после штамповки на механических прессах. При этом ЭГ калибровка деталей из высокопрочных сталей должна выполняться с предварительным созданием в них напряжений, близких к пределу текучести металла. Это позволяет более полно использовать процесс релаксации напряжений, при котором упругие деформации металла переходят в пластические.

Dobrov I. V., Semichev A. V. Improvement of the optical method for researching the contact stresses during the forging. Material working by pressure. 2020. № 1 (50). Р. 24-27.

The analysis of the results of experimental resarch of contact normal stresses during the forging of a symmetrical workpiece under conditions of plane deformation performed by the tensometric method is carried out. It is shown that when comparing the combined graphs of the distribution of contact normal stresses along the symmetry axis of the workpiece, depending on the position of the considered section of the workpiece relative to the length (diameter) of the contact surface, presented in the technical literature, it is necessary to take into account the real change in the dimensions of the contact surface during forging of the initial workpiece with different degrees of deformation. An optical method for research of the distribution of contact normal stresses during forging under conditions of plane deformation of a symmetric workpiece made of a material with high plastic properties, which during forging, flows into holes of equal diameter, located along the axis of symmetry at an equal distance from each other in the diaphanous puncheon of new design. The results of experimental expand the physical understanding of the nature of the redistribution of normal contact stresses during forging and qualitatively coincide with the results of load cell measurements of normal contact stresses in real conditions presented in the scientific and technical literature.

В роботі вирішено задачу уточнення моделі механічних властивостей матеріалу, що дозволяє підвищити достовірність математичного моделювання та точність визначення відповідних енергосилових параметрів процесів холодного розділення металу на ножицях. Зокрема відзначається, що при моделюванні методом скінченних елементів, з використанням методики побудови кривих текучості і пластичності матеріалу отриманих за результати статичних випробувань на розтяг, точність отримуваних результатів може бути підвищена. Вказується, що швидкість деформації при статичних випробуваннях, може коливатися в широкому діапазоні і це пояснюється величиною відносного подовження при розриві. Встановлено існування функціонального зв’язку та отримано рівняння для визначення швидкості деформації при статичних випробуваннях від відносного подовження при розриві. Застосування цього рівняння при моделюванні МСЕ дозволило зменшити відносну похибку до ± 7 %. Зроблено висновок, що запропонований метод буде сприяти розвитку математичного моделювання процесів різання на ножицях і поглибленню уявлень про процеси, що протікають в металі. Зокрема вивчався частинний вплив параметрів моделі механічних властивостей та умов реалізації процесів на результати моделювання. Були отримані залежності відношення максимального опору різанню при різних значеннях відносної швидкості різання, межи текучості, відносного подовження при розтягуванні, висоти розрізуваного перерізу до відповідних значень отриманих експериментальних даних. Загалом результати моделювання не протирічать загальним уявлення про процеси розділення металів у холодному стані. Результати роботи можуть бути рекомендовані для використання при прийнятті проектно-конструкторських і технологічних рішень в питаннях холодного поділу металу на ножицях.
The Incoherence of Moral Relativism
Authors: ALVARO Carlo
Published: July 2021

Abstract: This paper is a response to Park Seungbae’s article, “Defence of Cultural Relativism”. Some of the typical criticisms of moral relativism are the following: moral relativism is erroneously committed to the principle of tolerance, which is a universal
principle; there are a number of objective moral rules; a moral relativist must admit that Hitler was right, which is absurd; a moral relativist must deny, in the face of evidence, that moral progress is possible; and, since every individual belongs to multiple cultures at once, the concept
of moral relativism is vague. Park argues that such contentions do not affect moral relativism and that the moral relativist may respond that the value of tolerance, Hitler’s actions, and the concept of culture are themselves relative. In what follows, I show that Park’s adroit
strategy is unsuccessful. Consequently, moral relativism is incoherent.

Schizophrenia of Childhood: A Brief Overview
Authors: Rinu J George  , Shiny .T. Sam
Published: July 2021

Childhood schizophrenia is an uncommon but severe mental disturbance during which children interpretreality abnormally. Schizophrenia has no single cause; there are not well defined etiological factors of thiscondition. Distorted perception of reality confused thinking, detailed and bizarre thoughts and ideas aresome early symptoms of Childhood schizophrenia. According to the DSM-5, a diagnosis of schizophreniais made if a person has two or more core symptoms, one of which must be hallucinations, delusions, ordisorganized speech for at least one month. Childhood schizophrenia can be differentially diagnosed asautism because there are common symptoms among them. The management of Childhood schizophreniainclude anti psychotic drugs along with psychotherapies .a combined action of different modalities showsgood prognosis.
Notes on a Folio from the Gulshan Album in the Collection of the Náprstek Museum, Prague
Authors: Stříbrná Adriana
Published: July 2021

In 2015 the Naprstek Museum, in cooperation with the National Library of the Czech Republic, carried out a conservation survey of two rare folios from the Gulshan Album of the Mughal emperor Jahāngīr which form part of the Naprstek Museum’s Indian collection. During the survey an unknown signature by the painter Āqā Rezā was discovered in the border of one of them. The new finding was the impetus for this study, looking at the folio in more detail. In addition to the introductory part, which looks at the form and function of illustrated albums in the Mughal Empire, the study describes in detail both a miniature on one side of the folio and the calligraphy and border with human figures on the other side, and explains the relationship between them.

Galerijní výstavy a vlastivědná muzea
Authors: Mikule Stanislav
Published: July 2021

The paper is based on the author‘s practice in the Regional Museum in Žďár nad Sázavou. In many cities, museums and galleries are located side by side, and museums also hold gallery exhibitions. Museums of local history have considerable potential to supplement such an exhibition with the help of other museum collection objects of a non-artistic nature, such as the document of time of life and work of a given artist or related to the theme of the presented work. This makes the exhibition attractive to a wider range of visitors. The author describes art exhibitions in which collection items from various areas of human activity, realized in the Žďár Regional Museum, were connected and presents them as inspiration or a topic to reflect on colleagues from the field who do not yet use the potential of their collection items in a similar spirit.
When randomisation is not good enough: Matching groups in intervention studies
Authors: Sella Francesco , Raz Gal , Cohen Kadosh Roi
Published: July 2021

Randomised assignment of individuals to treatment and controls groups is often considered the gold standard to draw valid conclusions about the efficacy of an intervention. In practice, randomisation can lead to accidental differences due to chance. Researchers have offered alternatives to reduce such differences, but these methods are not used frequently due to the requirement of advanced statistical methods. Here, we recommend a simple assignment procedure based on variance minimisation (VM), which assigns incoming participants automatically to the condition that minimises differences between groups in relevant measures. As an example of its application in the research context, we simulated an intervention study whereby a researcher used the VM procedure on a covariate to assign participants to a control and intervention group rather than controlling for the covariate at the analysis stage. Among other features of the simulated study, such as effect size and sample size, we manipulated the correlation between the matching covariate and the outcome variable and the presence of imbalance between groups in the covariate. Our results highlighted the advantages of VM over prevalent random assignment procedure in terms of reducing the Type I error rate and providing accurate estimates of the effect of the group on the outcome variable. The VM procedure is valuable in situations whereby the intervention to an individual begins before the recruitment of the entire sample size is completed. We provide an Excel spreadsheet, as well as scripts in R, MATLAB, and Python to ease and foster the implementation of the VM procedure.

The Common Origin of High-energy Protons in Solar Energetic Particle Events and Sustained Gamma-Ray Emission from the Sun

We report that the number of >500 MeV protons (Ng
) inferred from sustained gamma-ray emission (SGRE) from the Sun is significantly correlated with that of protons propagating into space (N
SEP) as solar energetic particles (SEPs). Under the shock paradigm for SGRE, shocks driven by coronal mass ejections (CMEs) accelerate high-energy protons sending them toward the Sun to produce SGRE by interacting with the atmospheric particles. Particles also escape into the space away from the Sun to be detected as SEP events. Therefore, the significant N
SEP–N

g
correlation (correlation coefficient 0.77) is consistent with the common shock origin for the two proton populations. Furthermore, the underlying CMEs have properties akin to those involved in ground level enhancement events indicating the presence of high-energy (up to ∼GeV) particles required for SGRE. We show that the observed gamma-ray flux is an underestimate in limb events (central meridian distance >60°) because SGRE sources are partially occulted when the emission is spatially extended. With the assumption that the SEP spectrum at the shock nose is hard and that the 100 MeV particles are accelerated throughout the shock surface (half width in the range 60°–120°) we find that the latitudinal widths of SEP distributions are energy dependent with the smallest width at the highest energies. Not using the energy-dependent width results in an underestimate of N
SEP in SGRE events occurring at relatively higher latitudes. Taking these two effects into account removes the apparent lack of N
SEP–N

correlation reported in previous studies.
Collapsar R-process Yields Can Reproduce [Eu/Fe] Abundance Scatter in Metal-poor Stars
Authors: Brauer Kaley , Ji Alexander P. , Drout Maria R. , Frebel Anna
Published: July 2021

It is unclear if neutron star mergers can explain the observed r-process abundances of metal-poor stars. Collapsars, defined here as rotating massive stars whose collapse results in a rapidly accreting disk around a black hole that can launch jets, are a promising alternative. We find that we can produce a self-consistent model in which a population of collapsars with stochastic europium yields synthesizes all of the r-process material in metal-poor ([Fe/H] < − 2.5) stars. Our model reproduces the observed scatter and evolution of scatter of [Eu/Fe] abundances. We find that if collapsars are the dominant r-process site for metal-poor stars, r-process synthesis may be linked to supernovae that produce long γ-ray bursts. Our results also allow for the possibility that core-collapse supernovae beyond those that launch γ-ray bursts also produce r-process material (e.g., potentially a subset of Type Ic-BL supernovae). Furthermore, we identify collapsar jet properties (isotropic energy, engine luminosity, or engine time) that may trace r-process yield and verify that the amount of r-process yield produced per collapsar in our model ( ∼ 0.07M
⊙) is consistent with other independent estimates. In the future, achieving 0.05 dex precision on distribution scatter or a reliable selection function would further constrain our probe of r-process production. Our model would also hold for another prompt r-process site with a power-law yield, and work is needed to determine if, for example, fast-merging neutron stars can also explain abundance scatter.
Multiepoch Spectroscopy of Mg ii Broad Absorption Line Transitions
Authors: Yi Weimin , Timlin John
Published: July 2021

Built upon a sample of 134 quasars that was dedicated to a systematic study of Mg ii–BAL variability from Yi et al., we investigate these quasars, showing Mg ii–BAL disappearance or emergence with the aid of at least three epoch optical spectra sampled more than 15 yr in the observed frame. We identified 3/3 quasars undergoing pristine/tentative BAL transformations. The incidence of pristine BAL transformations in the sample is therefore derived to be

%, consistent with that of high-ionization BAL transformations from the literature. Adopting an average Mg ii–BAL disappearance timescale of rest frame 6.89 yr among the six quasars, the average characteristic lifetime of Mg ii BALs in the sample is constrained to be >160 yr along our line of sight. There is a diversity of BAL profile variability observed in the six quasars, probably reflecting a variety of mechanisms at work. Our investigations of Mg ii–BAL transitions, combined with observational studies of BAL transitions from the literature, imply an overall FeLoBAL/LoBAL → HiBAL/non-BAL transformation sequence, along with a decrease in reddening. This sequence is consistent with the evacuation models for the origin of commonly seen blue quasars, in which LoBAL quasars are in a short-lived blowout phase.
