This is the first time since the pandemic began with isolated cases in the early fall of 2019 in the city of Wuhan (CCP-China) that health authorities have completely lost control of the pandemic’s development without having any tool to counteract this evolving event. Sars-CoV-2 Omicron is unstoppable.

The purpose of the article is to present the history and the analysis of the Russian wooden sculpture “Nikola Мtsenskiy” results of the examination from Peter and Paul Cathedral in Mtsensk. For the first time, the author conducted a historical and cultural examination of this object for religious purposes. The article defines the historical and cultural context of this object existence, its veneration as a relic, the problem of comparing the “The Legend of the appearance of the miraculous icon of St. Nicholas Wonderworker in the city of Mtsensk” and the preserved sculpture. The author also examines the historical and artistic sources of origin of similar items in the culture of the medieval Moscow state. The author dates the preserved fragment of the sculpture from Mtsensk Peter and Paul Cathedral to the late 1600s.


Commissioned by the English East India Company to write about contemporary nineteenth-century Delhi, Mirza Sangin Beg walked around the city to capture its highly fascinating urban and suburban extravaganza. Laced with epigraphy and fascinating anecdotes, the city as ‘lived experience’ has an overwhelming presence in his work, Sair-ul Manazil. Sair-ul Manazil dominates the historiography of eighteenth- and nineteenth-century compositions on Delhi in Persian and Urdu, and remains unparalleled in its architecture and detailed content. It deals with the habitations of people, bazars, professions and professionals, places of worship and revelry, and issues of contestation. Over fifty typologies of structures and several institutions that find resonance in the Persian and Ottoman Empires can also be gleaned from Sair-ul Manazil. Interestingly, Beg made no attempt to ‘monumentalize’ buildings; instead, he explored them as spaces reflective of the sociocultural milieu of the times. Delhi in Transition is the first comprehensive English translation of Beg’s work, which was originally published in Persian. It is the only translation to compare the four known versions of Sair-ul Manazil, including the original manuscript located in Berlin, which is being consulted for the first time. It has an exhaustive introduction and extensive notes, along with the use of varied styles in the book to indicate the multiple sources of the text, contextualize Beg’s work for the reader and engage him with the debate concerning the different variants of this unique and eclectic work.

Akrotiri Salt Lake is located 5 km west of the city of Lemesos in the southernmost part of the island of Cyprus. The evolution of the Akrotiri Salt Lake is of great scientific interest, occurring during the Holocene when eustatic and isostatic movements combined with local active tectonics and climate change developed a unique geomorphological environment. The Salt Lake today is a closed lagoon, which is depicted in Venetian maps as being connected to the sea, provides evidence of the geological setting and landscape evolution of the area. In this study, for the first time, we investigated the development of the Akrotiri Salt Lake through a series of three cores which penetrated the Holocene sediment sequence. Sedimentological and micropaleontological analyses, as well as geochronological studies were performed on the deposited sediments, identifying the complexity of the evolution of the Salt Lake and the progressive change of the area from a maritime space to an open bay and finally to a closed salt lake.

In this study, we address the problem originated from the fact that “The Corona 19 Epidemiological Research Support System,” developed by the Korea Centers for Disease Control and Prevention, is limited to analyzing the Global Positioning System (GPS) information of the confirmed COVID-19 cases alone. Consequently, we study a method that the authority predicts the transmission route of COVID-19 between visitors in the community from a spatiotemporal perspective. This method models a contact network around the first confirmed case, allowing the health authorities to conduct tests on visitors after an outbreak of COVID-19 in the community. After securing the GPS data of community visitors, it traces back to the past from the time the first confirmed case occurred and creates contact clusters at each time step. This is different from other researches that focus on identifying the movement paths of confirmed patients by forward tracing. The proposed method creates the contact network by assigning weights to each contact cluster based on the degree of proximity between contacts. Identifying the source of infection in the contact network can make us predict the transmission route between the first confirmed case and the source of infection and classify the contacts on the transmission route. In this experiment, we used 64,073 simulated data for 100 people and extracted the transmission route and a top 10 list for centrality analysis. The contacts on the route path can be quickly designated as a priority for COVID-19 testing. In addition, it is possible for the authority to extract the subjects with high influence from the centrality theory and use them for additional COVID-19 epidemic investigation that requires urgency. This model is expected to be used in the epidemic investigation requiring the quick selection of close contacts.

AbstractShortly after the enactment of restrictions aimed at limiting the spread of COVID-19, various local government and public health authorities around the world reported an increased sighting of rats. Such reports have yet to be empirically validated. Here we combined data from multi-catch rodent stations (providing data on rodent captures), rodent bait stations (providing data on rodent activity) and residents’ complaints to explore the effects of a six week lockdown period on rodent populations within the City of Sydney, Australia. The sampling interval encompassed October 2019 to July 2020 with lockdown defined as the interval from April 1st to May 15th, 2020. Rodent captures and activity (visits to bait stations) were stable prior to lockdown. Captures showed a rapid increase and then decline during the lockdown, while rodent visits to bait stations declined throughout this period. There were no changes in the frequency of complaints during lockdown relative to before and after lockdown. There was a non-directional change in the geographical distribution of indices of rodent abundance suggesting that rodents redistributed in response to resource scarcity. We hypothesize that lockdown measures initially resulted in increased rodent captures due to sudden shortage of human-derived food resources. Rodent visits to bait stations might not show this pattern due to the nature of the binary data collected, namely the presence or absence of a visit. Relocation of bait stations driven by pest management goals may also have affected the detection of any directional spatial effect. We conclude that the onset of COVID-19 may have disrupted commensal rodent populations, with possible implications for the future management of these ubiquitous urban indicator species.

AbstractIn 2014 through 2018, Sichuan Provincial Institute of Cultural Relics and Archaeology and History Museum of Quxian County conducted a systematic archaeological survey, detection, and excavation to the Chengba site in Quxian County. The excavation uncovered 4,000sq m in total, from which 444 various features were recovered and over 1,000 artifacts were unearthed. The functional zoning of this site has been roughly made clear; the excavations of the western gate and important building foundations of the Guojiatai city site are important archaeological discoveries of the city sites of the Han through Western Jin dynasties, and at the checkpoint site on the waterway of this period was uncovered for the first time in China. The large amounts of bamboo slips and wooden tablets unearthed in the excavation provided important materials for the explorations on the management of the central government of the Han and Jin empires to the administrative areas of commandery and district levels and the social lives of the local people at that time.

AbstractBoth in the fourth book of Cicero’s De signis (Verr. 2,4) and in the fourteenth book of Silius Italicus’ Punica, there are descriptions of the city of Syracuse at important points of the texts. In this paper, both descriptions are combined and for the first time thoroughly related. I discuss form and content of the accounts, show their functions in their oratorical and epic contexts and consider their similarities. The most important facets, where the descriptions coincide in, seem to be their link to Marcellus’ conquest in the Second Punic War, the resulting precarious beauty of the city and the specifically Roman perspective on which these ekphraseis are based.

An artist who finds themselves in the last days of a war in the enemy’s defeated capital may not just fix its objects dispassionately. Many factors influence the selection and depicturing manner of the objects. One of the factors is satisfaction from the accomplished retribution, awareness of the historical justice triumph. Researchers think such reactions are inevitable. The article offers to consider from this point of view the drawings created by Soviet artists in Berlin in the spring and summer of 1945. Such an analysis of the German capital’s visual image is conducted for the first time. It shows that the above reactions were not the only ones. The graphics of the first post-war days no less clearly and consistently express other feelings and intentions of their authors: the desire to accurately document and fix the image of the city and some of its structures in history, the happiness from the silence of peace, and the simple interest in the monuments of European art.The article examines Berlin scenes as evidences of the transition from front-line graphics focused on the visual recording of the war traces to peacetime graphics; from documentary — to artistry; from the worldview of a person at war — to the one of a person who lived to victory. In this approach, it has been important to consider the graphic images of Berlin in unity with the diary and memoir texts belonging to both artists and ordinary soldiers who participated in the storming of Berlin. The combination of verbal and visual sources helps to present the German capital’s image that existed in the public consciousness, as well as the specificity of its representation by means of visual art.

The origins of the imperial cult in Smyrna date back to the Hellenistic period. It is a fact that political concerns were effective in the generation of such cults. Predicting the super power of the future and proving to be a loyal ally whilst acting in satisfactory behaviors were essential factors. The right preference made between two fighting or contending powers ensured that a city would benefit from various privileges in the future. For example, Symrna, which had established a cult in the city previously on behalf of Stratonice, the mother of Antiochus II of Seleucid dynasty, would do the same by building a temple in the name of the dty of Rome for the first time in Asia in 195 BC, after recognizing the rising power. Later on, while giving permission to the provinces that wanted to establish an imperial cult, the Roman emperors and the Senate would consider first, their relationships with Rome in the past and second, their origins. Smyrna, building its relationships with the Roman state on a solid basis, was granted the title of neokoros three times by the Roman Emperors Tiberius, Hadrianus and Caracalla, respectively. In this essay, the development of the Roman imperial cult in Smyrna is discussed within the historical process outlined above. An attempt has been made to put forth new opinions about the issue by discussing the academicians' evaluations on the imperial cult, which apparently was effectively executed in Smyrna between the first and third centuries AD, with the support of epigraphic and numismatic evidences.

SummaryThe Department of Urban Archaeology, City of London, was set up in December 1973 as part of Guildhall Museum, now the Museum of London. Since then it has excavated sixteen sites and carried out numerous watching briefs. Most of the formal excavations have been conducted on the vital waterfront sites, made available for the first time, and on the Roman and medieval defences of the City. Important evidence of the elusive Saxon occupation is gradually coming to light, and the work is accompanied by specialist research, particularly finds, environmental and documentary.
