Abstract The past 20 years have seen major public health emergencies and natural disasters, including the Severe Acute Respiratory Syndrome outbreak caused by the SARS-associated coronavirus (SARS-CoV) in 2003; the Wenchuan earthquake in 2008; and the novel coronavirus pandemic (COVID-19) of 2019, which caused mass casualties, infections, and panic. These also resulted in complex demands for medical resources and information, and a shortage of human resources for emergency responses. To address the shortage of human resources required for these emergency responses, Chinese dental professionals made useful contributions. From this work, deficiencies in emergency response training and opportunities for the expansion of rescue capabilities were identified, and relevant recommendations made.

Emergency trauma radiology, although a relatively new subspecialty of radiology, plays a critical role in both the diagnosis/triage of acutely ill patients, but even more important in providing leadership and taking the lead in the preparedness of imaging departments in dealing with novel highly infectious communicable diseases and mass casualties. This has become even more apparent in dealing with COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, first emerged in late 2019. We review the symptoms, epidemiology, and testing for this disease. We discuss characteristic imaging findings of COVID-19 in relation to other modern coronavirus diseases including SARS and MERS. We discuss roles that community radiology clinics, outpatient radiology departments, and emergency radiology departments can play in the diagnosis of this disease. We review practical methods to reduce spread of infections within radiology departments.

In this study, the concept, basic theory and application of the management of social media in major public health emergencies were expounded with the management of social media in the novel coronavirus pneumonia as the breakthrough point. With the related reports or information of the novel coronavirus pneumonia as the analysis sample, the role of social media in the pandemic was discussed from multiple aspects and perspectives by using the method of content analysis. On this basis, the management strategies of social media in major public health emergencies were further proposed.

SARS-COV2 virus causes Coronavirus disease (COVID-19) and represents the causative agent of a potentially fatal disease that is of great global public health concern. The novel coronavirus (2019) was discovered in 2019 in Wuhan, the market of the wet animal, China with viral pneumonia cases and is life-threatening. Today, WHO announces COVID-19 outbreak as a pandemic. COVID-19 is likely to be zoonotic. It is transmitted from bats as intermediary animals to human. Also, the virus is transmitted from human to human who is in close contact with others. The computerized tomographic chest scan is usually abnormal even in those with no symptoms or mild disease. Treatment is nearly supportive; the role of antiviral agents is yet to be established. The SARS-COV2 virus spreads faster than its two ancestors, the SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV), but has lower fatality. In this article, we aimed to summarize the transmission, symptoms, pathogenesis, diagnosis, treatment, and vaccine to control the spread of this fatal disease.

This booklet is a collection of the position statements accepted for the HRI’20 conference workshop “Social Cognition for HRI: Exploring the relationship between mindreading and social attunement in human-robot interaction” (Wykowska, Perez-Osorio & Kopp, 2020). Unfortunately, due to the rapid unfolding of the novel coronavirus at the beginning of the present year, the conference and consequently our workshop, were canceled. On the light of these events, we decided to put together the positions statements accepted for the workshop. The contributions collected in these pages highlight the role of attribution of mental states to artificial agents in human-robot interaction, and precisely the quality and presence of social attunement mechanisms that are known to make human interaction smooth, efficient, and robust. These papers also accentuate the importance of the multidisciplinary approach to advance the understanding of the factors and the consequences of social interactions with artificial agents.

Forgetting and remembering are as inevitably linked as lifeand death. Sometimes, forgetting is motivated by a biological disorder, brain damage, or it is the product of an unconscious desire derived from a traumatic event (psychological repression). But in some cases, we can motivate forgetting consciously (thought suppression). It is through the conscious repression of memories that we can find self-preservation and move forward, although this means that we create a fable of our lives, as Nietzsche says in his essay “On the Uses and Disadvantages of History for Life” (1997). In Jonathan Franzen’s novel, Purity (2015), forgetting is an active and conscious process by which the characters choose to forget certain episodes of their lives to be able to construct new identities. The erased memories include murder, economical privileges derived from illegal or unethical commercial processes, or dark sexual episodes. The obsession with forgetting the past links the lives of the main characters, and structures the narrative of the novel. The motivated erasure of memories becomes, thus, a way that the characters have to survive and face the present according to a (fake) narrative that they have constructed. But is motivated forgetting possible? Can one completely suppress facts in an active way? This paper analyses the role of forgetting in Franzen’s novel in relation to the need in our contemporary society to deny, hide, or erase uncomfortable data from our historical or personal archives; the need to make disappear stories which we do not want to accept, recognize, and much less make known to the public. This is related to how we manage information in the age of technology, the “selection” of what is to be the official story, and how we rewrite our own history

Abstract Background: The outbreak of coronavirus disease (COVID-19) was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), through its surface spike glycoprotein (S-protein) recognition on the receptor Angiotensin-converting enzyme 2 (ACE2) in humans. However, it remains unclear how genetic variations in ACE2 may affect its function and structure, and consequently alter the recognition by SARS-CoV-2. Methods: We have systemically characterized missense variants in the gene ACE2 using data from the Genome Aggregation Database (gnomAD; N = 141,456). To investigate the putative deleterious role of missense variants, six existing functional prediction tools were applied to evaluate their impact. We further analyzed the structural flexibility of ACE2 and its protein-protein interface with the S-protein of SARS-CoV-2 using our developed Legion Interfaces Analysis (LiAn) program.Results: Here, we characterized a total of 12 ACE2 putative deleterious missense variants. Of those 12 variants, we further showed that p.His378Arg could directly weaken the binding of catalytic metal atom to decrease ACE2 activity and p.Ser19Pro could distort the most important helix to the S-protein. Another seven missense variants may affect secondary structures (i.e. p.Gly211Arg; p.Asp206Gly; p.Arg219Cys; p.Arg219His, p.Lys341Arg, p.Ile468Val, and p.Ser547Cys), whereas p.Ile468Val with AF = 0.01 is only present in Asian.Conclusions: We provide strong evidence of putative deleterious missense variants in ACE2 that are present in specific populations, which could disrupt the function and structure of ACE2. These findings provide novel insight into the genetic variation in ACE2 which may affect the SARS-CoV-2 recognition and infection, and COVID-19 susceptibility and treatment.

A review of the anthology prepared by N. Lopatina, a renowned Russian bibliographer. The collection includes 187 translations of Goethe’s 78 poems, which are quoted in the original language, and of several poetic fragments from the tragedy Faust, the novel Wilhelm Meister, as well as the cycle West-Eastern Divan, made by 63 Russian 19th-c. poets, representatives of various traditions — from Classicism and Sentimentalism to Symbolism and Acmeism. The collection showcases the high achievements of the country’s school of poetic translation and acute cultural awareness of the Russian society in the 19th c., and focuses on the part of Goethe’s poetic oeuvre that was especially popular with the Russian reader. Another role of the anthology is to bridge a gap in our knowledge and uncover names, often unfairly forgotten, of Russian poets and philologists of the past in their interaction with the Western European literature.

Abstract This survey reports on motive power developments for the previous year ending in August 2020. Invitations to collaborate were sent to several locomotive builders and railroads. The survey looks at the scope of new and rebuilt motive power during the past year. During this time, several Class 1 railroads have heavily adopted the rebuilding and modernization of existing motive power. The survey also looks at how the needs of the railroads are changing in terms of motive power both due to Precision Scheduled Railroading (PSR) and also due to the novel Coronavirus pandemic. Finally, this survey will conclude with a look back at the high horsepower race following the retirement of the EMD SD80MAC locomotives from Class 1 ownership.

This chapter explores connections between two treatments of history in science fictional literature—the apocryphal history and the alternate history—as they deal with material place. Theorists (Jameson, Hughes-Warrington) have explored the role of materialist history in our need to create counterfactuals by examining the cityscapes and structures in literary representations of the past. This essay connects the disparate strands of materialism, place, and religious revisionism via Juan Miguel Aguilera’s La locura de Dios. It reads the novel as both an apocryphal adventure to a “lost world” civilization and an alternate narrative of Spanish national history. La locura comments surprisingly self-consciously on the crystalline fragility of the logic holding material history together, threatened as it is by a revisionist, escapist orthodoxy.

Over the past several months, an increasing volume of infor- mation has expanded awareness regarding the transmission of SARS-CoV-2, the novel coronavirus associated with COVID-19. Following the pandemic declaration by the World Health Orga- nization (WHO), global authorities immediately took measures to reduce the transmission and subsequent morbidity associa- ted with this highly contagious disease. However, despite initial success in “flattening the curve” of viral transmission, many areas of the world are currently experiencing an increase in com- munity transmission, threatening to replicate the early public health emergencies experienced by Italy (1,2). In addition, the possibility of contact tracing through geosocial applications and public service platforms have been met with variable interest (3). Given current spread and the upcoming influenza season, it is essential that we use our voices as experts in upper airway health and disease to educate and encourage all communities to adopt appropriate protective measures, including the routine use of facemasks.
