Urban Resilience of Metropolitans in the Mid-Latitude Coastal Regions of East Asia for Global Weather Anomalies
Authors: Song Youngbae , Song Jaeyi
Published: August 2023

Weather patterns in cities located in both the eastern and western coastal regions of the Pacific may tend to change coupled with global weather anomalies. This study analyzes temperature variabilities in the western coastal region of the Pacific associated with LST, NDVI, and ONI over the past 57 years. The results indicate that the temperature rise was 0.34°C, significantly higher than global warming of 0.15 to 0.20°C per decade. El Niño/La Niña events typically reach the East Asian coastal regions 4 to 6 months after their occurrence, and their impact seems more severe in the following year. El Niño influenced the formation of high temperatures and remained high even after neutralization. La Niña led to significant temperature drops and extended cold waves; this climate phenomenon greatly differs from the typical region-specific climate over a long period. Spatiotemporal distributions of LST revealed that weather anomalies significantly influenced urban greenery and forests, which suffered from physiological stresses, compromising their ability to provide ecosystem services that protect against climate change or mitigate their impacts. NDVI-Mass values increased with rising temperatures caused by El Niño but decreased drastically with low vegetation vitality at low temperatures caused by La Niña. Urban greenery and forests recover after absorbing the impact of global weather anomalies but experience a short-term loss of 5% and an average long-term loss of approximately 1% in NDVI-Mass yearly. This continuous loss indicates a lack of equilibrium from 1985 to the present. Regional warming in the study area has continued to rise.
Association of chronic morbidity and early retirement in India: Evidence from Longitudinal Ageing Study in India
Authors: Akhtar Shamrin , Mohanty Sanjay K
Published: August 2023

Context:
Chronic diseases have a profound impact on productivity and job interest, often resulting in significant losses in both. Numerous scientific research has shown that chronic illnesses have a negative impact on work-related outcomes. The findings of these studies highlight the importance of studying the association of chronic morbidity and early retirement by addressing chronic diseases comprehensively in the workplace to promote employee well-being, productivity, and overall work satisfaction.
Methods
The initial phase of the Longitudinal Ageing Study in India (LASI) was utilized, focusing on outcome variables related to early retirement caused by poor health. Through multivariate analysis using a probit regression model, we evaluated the correlation between early retirement and specific chronic diseases, as well as the cumulative number of chronic diseases and other sociodemographic factors.
Findings:
Neurological problems and stroke were those showing the strongest association with early retirement, followed by chronic lung and heart diseases. Among other covariates, the risk of retirement was significantly lower among the currently married and rural sector. Considering socioeconomic characteristics, subjects with lower education were significantly at higher risk of early retirement.
Conclusions
We observed a statistically significant connection between chronic health conditions and early retirement among individuals nearing the age for receiving statutory pensions, even after accounting for potential confounding factors. The association between health issues and early retirement was particularly pronounced among subjects affected by stroke and neurological problems. The study results highlight the importance of developing interventions aimed at enhancing prevention and treatment of chronic illnesses, as well as creating workplace accommodations for individuals with health issues, in order to bolster labor force participation rates among older workers

Previous studies on horseshoe bats (Rhinolophus spp.) have described many coronaviruses related to SARS-CoV (SARSCoVr) in China and only a few coronaviruses related to SARS-CoV-2 (SARSCoV2r) in Yunnan, Cambodia, Laos and Thailand. Here, we report the results of several field missions carried out in 2017, 2021 and 2022 across Vietnam during which 1,218 horseshoe bats were sampled. We assemble 38 Sarbecovirus genomes: 26 SARSCoVr from R. thomasi; six SARSCoVr and four SARSCoV2r from R. affinis; and two recombinants of SARSCoVr and SARSCoV2r from R. pusillus, one showing a receptor-binding domain of the Spike protein very similar to SARS-CoV-2. We detected a bat co-infected with four coronaviruses, including two sarbecoviruses. Our phylogeographic analysis suggests a divergent evolution between sarbecoviruses from subtropical northern Vietnam and those from tropical southern Vietnam, emergence of SARS-CoV in horseshoe bats from northern Yunnan and emergence of SARS-CoV-2 in horseshoe bats from southern Yunnan.
Site Formation Process Studies as Aircraft Site Identification: A WWII-era Flying Boat Case Study
Authors: Pruitt James , McKinnon Jennifer F
Published: August 2023

Compared to the study of shipwrecks, the investigation of submerged aircraft is relatively recent in underwater archaeology. With the passing of time and the addition of World War II (WWII) sites to historical registers, the inclusion of aircraft in the Sunken Military Craft Act of 2004, and the continued expansion of the Defense POW/MIA Accounting Agency’s (DPAA) mission to recover lost pilots and crew, these studies have become increasingly important to a variety of stakeholders. Site formation process (SFP) studies stipulate that a crucial aspect of the accurate investigation and interpretation of a site first requires a thorough understanding of the processes that created and subsequently altered the site. For terrestrial archaeologists, as well as maritime archaeologists studying shipwreck sites, a well-established database of such knowledge already exists. For submerged aircraft, however, this database is small, yet growing. This paper will contribute to the understanding and interpretation of submerged aircraft sites through the study of the processes that created and subsequently affected a submerged WWII-era PB2Y Coronado aircraft located in Tanapag Lagoon, Saipan, Commonwealth of the Northern Mariana Islands (CNMI). Archaeological and historical evidence is examined through the lens of SFP studies to identify the specific aircraft, determine its cause of crash, and understand cultural and natural factors that have impacted the site and may affect it today.

Published: August 2023

Background
Circulating tumor DNA (ctDNA) has emerged as a potential diagnostic and prognostic biomarker in various tumors. However, the role of tumor suppressor genes (TSGs) methylation in ctDNA of patients with pancreatic cancer (PC) remains largely unclear.
Methods
Patients with PC (n = 43), pancreatic benign diseases (n = 39), and healthy controls (n = 20) were enrolled in the study. Quantitative analysis of methylation pattern of five candidate TSGs including NPTX2, RASSF1A, EYA2, p16, and ppENK in ctDNA was performed by next generation sequencing (NGS). The diagnostic performances of these 5-TSGs methylation were assessed by the operating characteristic (ROC) curve and clinicopathological features correlation analysis. Meanwhile, the changes in methylation levels of these 5-TSGs on the 7th postoperative day were evaluated in 23 PC patients who underwent radical resection.
Results
The methylation levels of RASSF1A, EYA2, ppENK and p16 genes in patients with PC were significantly higher than those in healthy controls. EYA2, p16 and ppENK genes showed significantly hypermethylation in PC than those in pancreatic benign diseases. NPTX2, RASSF1A, EYA2, p16 and ppENK genes showed significantly hypermethylation in pancreatic benign diseases than those in healthy controls (P < 0.05). The methylation levels of these 5 candidate TSGs were not correlated with the tumor size, nerve invasion, lymph node metastasis and TNM stage of PC. The AUC of these biomarkers for diagnosis of PC ranged from 0.65 to 0.96. The AUC values of these methylated genes and CpG sites for differentiating malignant and benign pancreatic diseases were ranging from 0.68 to 0.92. Combined the hypermethylated genes improved the detective ability of PC than single gene. The methylation levels of NPTX2, EYA2 and ppENK genes were significantly decreased after radical resection of PC.
Conclusion
Quantitative analysis of methylation pattern of NPTX2, RASSF1A, EYA2, p16 and ppENK in ctDNA by NGS could be a valuable non-invasive tool for detection and monitoring of PC.

Published: August 2023

Household travel surveys have been used for decades to collect individuals and households’ travel behavior. However, self-reported surveys are subject to recall bias, as respondents might struggle to recall and report their activities accurately. This study addresses examines the time reporting error of public transit users in a nationwide household travel survey by matching, at the individual level, five consecutive years of data from two sources, namely the Danish National Travel Survey (TU) and the Danish Smart Card system (Rejsekort). Survey respondents are matched with travel cards from the Rejsekort data solely based on the respondents’ declared spatiotemporal travel behavior. Approximately, 70% of the respondents were successfully matched with Rejsekort travel cards. The findings reveal a median time reporting error of 11.34 minutes, with an Interquartile Range of 28.14 minutes. Furthermore, a statistical analysis was performed to explore the relationships between the survey respondents’ reporting error and their socio-economic and demographic characteristics. The results indicate that females and respondents with a fixed schedule are in general more accurate than males and respondents with a flexible schedule in reporting their times of travel. Moreover, trips reported during weekdays or via the internet displayed higher accuracies compared to trips reported during weekends and holidays or via telephones. This disaggregated analysis provides valuable insights that could help in improving the design and analysis of travel surveys, as well accounting for reporting errors/biases in travel survey-based applications. Furthermore, it offers valuable insights underlying the psychology of travel recall by survey respondents.

Seaweeds are considered an essential source of metabolites and molecules in novel drug research. The existence of antimicrobial, antimutagenic, antioxidant, anti-cancer etc., effects of active compounds has been proven. Cancer, characterized by changes in the expression of multiple genes, is a widespread disease leading to death worldwide. To contribute to the novel drug discovery research, we aimed to determine the anti-cancer activities of 10 macroalgae by performing cytotoxicity, apoptosis, and total antioxidant and gene expression analysis of selected macroalgae species. IC50 values ​​of the extracts of selected algae species were determined by Water-Soluble Tetrazolium (WST) analysis. Hexane extract of D. dichotoma var. intricate, methanol extract of A. nayadiformis, and methanol extract of the green algae U. lactuca showed the best cytotoxic activities. Also, the dichloromethane extract of D. dichotoma var. intricate showed the best apoptotic effect by inhibiting 77.4% of the cells in apoptosis analyses on the K562 cell line. According to the total antioxidant analysis results, the C. circinatum showed the best antioxidant activity in hexane extracts with 165.11% inhibition; P. pavonica species showed the lowest DPPH radical scavenging activity with 6.22% inhibition. D. dichotoma var. intricate extracts showed promising anti-cancer activity among others. Finally, the revealed selected target genes' expression profile indicated that regulation was observed, especially in the JAK-STAT pathway forthcoming actors with induced pro-apoptotic genes and downregulated oncogenes. These results point out that the algae extracts could be promising agents for CML therapy either as mono or combined treatments.

Published: August 2023

β-asarone, the main active component ofAcori tatarinowiirhizoma (ATR), exhibits several pharmacological properties, including anti-inflammatory, anti-aging, and neuroprotective effects. In recent years, a large number of studies have shown that β-asarone exerts a positive effect on improving the cognitive level of individuals with Alzheimer’s disease (AD). However, the effects of β-asarone on autophagy in neuroinflammation-induced AD and the potential underlying mechanisms remain unclear. In the present study, we found that β-asarone inhibited LPS-induced activation of NHA cells and significantly decreased the expression of inflammatory factors andsparc. Exposure to exogenous SPARC promoted apoptosis and autophagy in neuronal cells. Further, we co-cultured LPS-induced reactive human astrocytes [NHA (normal human astrocytes)] with human neuronal cells (SH-SY5Y cell line) to establish a neurocyte inflammatory microenvironment to mimic the neuroinflammatory model of ADin vitro. Based on the above co-culture system, we observed that after SPARC overexpression in NHA, the behavior of the neuronal cells resembled that after exogenous SPARC treatment. However, β-asarone treatment reversed these effects and protected the cells against neuronal damage. These findings suggested that the matrix protein SPARC plays an important role in neuronal damage in AD model mice, and β-asarone intervention can be utilized as a potential therapeutic strategy for AD.
Monotonicity of solutions for fractional parabolic equations
Authors: Liu Gemei
Published: August 2023

In this paper, we consider the following fractional parabolic equation with a gradient nonlinear term on the upper half space
\begin{equation*}
\begin{cases}
\frac{\partial u}{\partial t}(x, t)+(-\Delta)^s u(x, t)=f(t,x,u(x,t),\triangledown u(x,t)),& (x, t) \in \mathbb{R}_+^{n} \times \mathbb{R}, \\u(x, t) = 0,& (x, t) \notin \mathbb{R}_+^{n} \times \mathbb{R}.
\end{cases}
\end{equation*}
Without assuming any asymptotic decay of $u$ near infinity, we prove that~$u(x,t)$~is strictly increasing with respect to $x_1$ by the method of moving planes. Meanwhile, we show the existence of positive solutions related to the fractional parabolic equations on the whole space $\mathbb{R}^{n-1}.$
Herpes simplex virus infection induces necroptosis of neurons and astrocytes in human fetal organotypic brain slice cultures
Authors: Rashidi Ahmad , Tran Diana , Peelen Caithlin , Gent Michiel van , Ouwendijk Werner , Verjans Georges
Published: August 2023

Background Herpes simplex virus (HSV) encephalitis (HSE) is a serious and potentially life-threatening disease, affecting both adults and newborns. Progress in understanding the virus and host factors involved in neonatal HSE has been hampered by the limitations of current brain models that do not fully recapitulate the tissue structure and cell composition of the developing human brain in health and disease. Here, we developed a human fetal organotypic brain slice culture (hfOBSC) and determined its value in mimicking the neuropathology of HSE in vitro .Methods Cell viability and tissues integrity were determined by lactate dehydrogenase release in supernatant and detailed immunohistological (IHC) analyses. Brain slices were infected with green fluorescent protein (GFP-) expressing HSV-1 and HSV-2. Virus replication and spread were determined by confocal microscopy, PCR and virus culture. Cell tropism and HSV-induced neuropathology was determined by IHC analysis. Finally, the in situ data of HSV-infected hfOBSC were compared to the neuropathology detected in human HSE brain sections.Results Slicing and serum-free culture conditions were optimized to maintain the viability and tissue architecture of ex vivo human fetal brain slices for at least 14 days at 37oC in a CO2 incubator. The hfOBSC supported productive HSV-1 and HSV-2 infection, involving predominantly infection of neurons and astrocytes. Both viruses induced programmed cell death – especially necroptosis – in infected brain slices at later time points after infection. The virus spread, cell tropism and role of programmed cell death in HSV-induced cell death closely mimicked the neuropathology of HSE.Conclusions We developed a novel human brain model in which the viability of the major brain-resident cells – including neurons, microglia, astrocytes and oligodendrocytes – and the tissue architecture is maintained for at least 2 weeks in vitro under serum-free conditions. The close resemblance of cell tropism, spread and neurovirulence of HSV-1 and HSV-2 in the hfOBSC model with the neuropathological features of human HSE cases underscores its potential to detail the pathophysiology of other neurotropic viruses and as preclinical model to test novel therapeutic interventions.

Authors: Luo mingwei , Xie shiwei , Pang jie , Yan jing , Xu huamin
Published: August 2023

Background
Medical education needs to strengthen its focus on improving the humanistic quality of medical students while improving their medical knowledge and skills. This study aims to identify and integrate the current literature and research hotspots on raising medical students' humanistic literacy to provide a reference for researchers.
Methods
CiteSpace is a Java application which supports visual exploration with knowledge discovery in bibliographic databases. We searched the China Knowledge Network (CNKI) database for articles published between 1995 and 2022. "Humanistic quality of medical students" was the key search term. Titles and abstracts were screened and extracted according to the inclusion and exclusion criteria. The CiteSpace software was used to retrieve 941 humanistic quality journal articles geared toward medical students from the CNKI database up to April 2022. A comprehensive review was conducted on these articles to reveal the current situation and hotspots of research aimed at improving medical students’ humanistic quality.
Results
The study found that the number of publications on humanities literacy research for medical students has increased overall over the past 20 years, although a certain graph shows an inverted S-shaped fluctuation. Research on improving the humanistic quality of Chinese medical students is predominantly conducted by medical colleges. No single author or institutional core group dominates the field of research on medical students' humanistic qualities. The main study focuses on humanistic qualities, medical students, higher vocational students, and higher vocational colleges.
Conclusion
Based on the research trends of medical students' humanistic literacy, combined with CiteSpace’s visual knowledge maps, this study provides an in-depth understanding of the main authors, institutions, and research hotspots in humanistic literacy for medical students. The information in this study is most valuable to researchers interested in medical student education. This study summarizes the current development and ideological foundations of humanistic literacy among medical students in China. This study helps researchers to grasp the scientific development and research issues in the field of humanistic literacy of medical students in China.

Authors: Ma Wanshan , Cui Xiaodi , Dong Xiutao , Li Xinpeng , Wang Yujiao , Shi Xiaohong , Chen Liang , Hao Mingju
Published: August 2023

Background
Salmonella enterica is a significant public health concern due to its ability to cause foodborne illnesses worldwide. To gain insights into the epidemiology and characteristics of Salmonella strains in China, a total of 20 Salmonella isolates were subjected to phenotypic and molecular analyses.
Methods
The 20 Salmonella strains were characterized through serotype identification, antimicrobial susceptibility testing (AST), biofilm formation assessment and plasmid transmission studies. Molecular characteristics and relatedness were determined using pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). Additionally, SNP-based phylogenetic analysis and core genome multilocus sequence typing (cgMLST) were employed to contextualize the strains among previously sequenced S. enterica isolates in China and worldwide.
Results
The predominant serovar identified was Salmonella enterica serovar Enteritidis (S. Enteritidis), followed by S. Mbandaka, Thompson, Livingston, Alachua, and Infantis. The SNP-based phylogenetic analysis revealed substantial diversity among S. Enteritidis isolates, with a minimum of 32 SNPs between strains. Conversely, S. Mbandaka isolates were suspected to have originated from a single clonal expansion, displaying a difference within 6 SNPs. SNP-based phylogenetic analysis suggested S. Mbandaka clone in this study was likely to have been derived from a single source that persisted over 5 years in China. S. Mbandaka, Infantis, Livingston, and Alachua exhibited susceptibility to the tested antibiotics, while strains of S. Thompson and Enteritidis demonstrated resistance to ampicillin, quinolone, and sulfamethoxazole/trimethoprim (SMZ/TMP). Particularly concerning was the identification of one S. Enteritidis isolate carrying the highly transferable IncB/O/K/Z plasmid with blaCTX−M15, conferring cephalosporin resistance. Another isolate, harboring the mrkABCDF operon in an IncX1 plasmid, isolated from cutaneous lesions, demonstrated robust biofilm formation.
Conclusions
Our study emphasizes the importance of SNP-based surveillance and prompt response to Salmonella infections to protect public health. The dissemination of blaCTX−M15-harboring IncB/O/K/Z plasmid and the spread of virulent mrkABCDF operon among S. enterica in China and other global regions warrant close monitoring.
Systematic Engineering of Properties of Graphene Quantum Dots by Aryl Amines
Authors: Rani Priya , Srivast Sunita
Published: August 2023

Graphene quantum dots (GQDs) are becoming an efficient nanomaterial to control their optoelectronic properties by molecular engineering due to the advantages of tunability by size, shape, doping, and comparatively low degree of toxicity and a great extent of spatial confinement. Their bandgap can be tuned effectively by functionalization of their surface or edges with some specific groups. In the present study, systematic efforts have been made to tune the band gap and corresponding optical properties of the GQDs by functionalizing them with different aryl amine groups because of their potential for extremely strong and wide-ranging light absorption; these GQDs have also been demonstrated to be advantageous for photocatalysis. The absorption and fluorescence spectra have been investigated by employing density functional theory with Becke three parameters hybrid functional with Lee-Yang-Perdew (B3LYP) correlation functional as implemented in Gaussian 09 package. Functionalization with such aryl amine groups accounts for the decrement in band gap and shift of absorption spectra towards longer wavelength. Such narrow band gap GQDs are highly required for the applications such as photocatalysis and bio-imaging etc. The outcomes achieved in this way are highly consistent with other experimental findings.

Published: August 2023

Spatial transcriptomics produces high-dimensional gene expression measurements while retaining their spatial context within tissues. Obtaining a biologically meaningful low dimensional presentation of the data is a crucial step toward data interpretation and downstream analysis. Here, we present STAMP, an interpretable spatially aware dimension reduction method built on a deep generative model that returns low dimensional topics of biologically relevant spatial domains and associated gene modules. STAMP recovered the anatomical structures of the mouse hippocampus and olfactory bulb with known gene markers highly ranked in the respective gene modules. In a lung cancer sample, it delineated cell states with supporting gene markers at a higher resolution than the original annotation and uncovered a topic of cancer associated fibroblasts. Finally, we expanded STAMP to account for batch effects and identify spatiotemporal patterns across chronologically consecutive samples of mouse embryo development. STAMP is implemented in Python and downloadable at https://github.com/JinmiaoChenLab/scTM.
How structural change affects economic vulnerability: Evidence from resource-rich countries in sub-Saharan Africa.

Published: August 2023

The goal of this essay is to assess how structural transformation indicators affect economic vulnerability of resource-rich countries in sub-Saharan Africa. Using data from 26 nations covering the period from 1996 to 2020, we estimate a linear model with the FM-OLS method. Overall, our findings indicate that while industrial employment has an amplifying effect on vulnerability, employment in the service sector, industrial value added, and value contributed in the service sector all contribute little to lessening economic vulnerability. Our findings hold up well to changes in estimating methodology (PCSE). By taking into account the distinctive features of the CFA Franc and non-CFA Franc monetary zones, sensitivity is evaluated. Therefore, we advocate for the creation of an institutional framework that places special emphasis on vocational training, so that industrial employment is no longer restricted to manoeuvring tasks, on the efficient distribution of NR rents, and on the relentless fight against corruption and embezzlement of public funds, which slow down the process of structural transformation and, consequently, of creating strong shock-resistant economies. These measures need to be stepped up in the Franc zone countries, which, according to the study, are performing less well than other monetary systems.

Multi-Graph Neural Network based Personalized Recommendation Model for Multimodal Data
Authors: Navarro Carlos , Brown Winona , Anderson Phineas , Hernandez Emilio
Published: August 2023

Collaborative filtering based recommendation methods make recommendations based on the preference information of other users who are similar to the user. The method is based on the assumption that human beings tend to form their own opinions from the reviews and opinions of similar groups. Compared with the original recommendation methods, the graph neural network recommendation method not only learns the topology of the graph network but also aggregates the various adjacencies of neighboring nodes, so that it can learn the information in the graph network more efficiently and play a key role for the subsequent recommendation. How to describe and represent the video and the user is the basis for video recommendation and determines the performance of the recommender system. Aiming at the above problems, this paper proposes a recommendation model based on a multi-graph neural network. The model utilizes the property that graph neural networks can mine the deep information of graph data more effectively and transforms the input user rating information and item side information into multiple graphs for effective feature extraction. From the perspective of multimodal semantics, a video similarity metric learning method based on semantic information is proposed. As videos contain different media types, different media types have different features. By analyzing the different media features and representing the multiple modal features in a unified way, we make a foundation for realizing the recommendation of videos.
A Novel Framework for Concept Drift Detection for Classification Problems in Data Streams
Authors: Ali Usman , Mahmood Tariq
Published: August 2023

In streaming data environments, data characteristics and probability distributions are likely to change over time, causing a phenomenon called concept drift, which poses challenges for machine learning models to predict accurately. In such non-stationary environments, there is a need to detect concept drift and update the model to maintain an acceptable predictive performance. Existing approaches to drift detection have inherent problems like requirements of truth labels in supervised detection methods and high false positive rate in case of unsupervised drift detection. In this paper, we propose a semi-supervised Autoencoder based Drift Detection Method (AEDDM) aimed at detecting drift without the need of truth labels, yet with a high confidence that the detected drift is real. In a binary classification setting, AEDDM uses two autoencoders in a layered architecture, trained on labelled data and uses a thresholding mechanism based on reconstruction error to signal the presence of drift. The proposed method has been evaluated on four synthetic and four real world datasets with different drifting scenarios. In case of real-world datasets, the induced and detected drifts have been evaluated from classifier’s performance viewpoint using seven mostly used batch classifiers as well as from adaptation perspective in an online learning environment using Hoeffding Tree classifier. The results show that AEDDM affectively detects the distributional changes in data which are most likely to impact the classifier’s performance (real drift) while ignoring the virtual drift thus considerably reducing the false alarms with an ability to adapt in terms of classification performance.
Numerical Estimation for the Three-Parameter Burr-XII Model Based on Picard’s Method
Authors: Maswadah M.
Published: August 2023

In parameter estimation techniques, there are several methods for estimating the distribution parameters in life data analysis. However, most of them are less efficient than Bayes’ method based on the informative prior. Thus, the main objective of this study is to present an optimal numerical technique, Picard’s method, for estimating Burr type-XII distribution parameters and compare them with Bayes’ method based on the informative gamma and kernel priors. A comparison between these estimators is provided using an extensive Monte Carlo simulation. The simulation results indicated that Picard’s method is highly favorable, which provides better estimates and outperforms Bayes’ method based on the generalized progressive hybrid censoring scheme. Finally, two real dataset analyses are presented to illustrate the efficiency of the proposed methods.
Uma análise da resposta do ocidente à invasão russa da Ucrânia sob o prisma da trindade da Guerra de Clausewitz
Authors: de Araújo Pângaro Emerson Luis , Leite de Almeida Leandro
Published: August 2023

A invasão da Ucrânia por tropas russas no final de fevereiro de 2022 trouxe o mundo ao perigo de uma nova polaridade: Rússia x Países Ocidentais liderados pelo bloco da OTAN (Organização do Tratado do Atlântico Norte). Fatores históricos, a importância geográfica da Ucrânia para Rússia e o risco que as nações ocidentais veem na expansão territorial russa rumo ao leste europeu tornam a solução do conflito cada vez mais complexa. Diante desse quadro sombrio, o ocidente vem adotando soluções para tentar desestimular a invasão russa sem o emprego de tropas da OTAN em apoio ao Exército Ucraniano. Este artigo busca traçar cenários de possíveis estratégias a serem adotadas pelos países ocidentais, com enfoque nos integrantes da OTAN, por meio da análise da trindade da guerra de Clausewitz.

Verbal and musical texts: Interactions of semiotic codes
Authors:   St. Petersburg State University, Dmitrieva Maria
Published: August 2023

The purpose of the paper is to identify the mechanisms of interaction between two sign systems: the verbal text of the Dutch rhymed psalms of the 19th century and the musical text of the melodies. The text is broadly understood as an ordered set of semiotic codes that carry certain information. The discussion of both linguistic and musical material with the use of musicological and linguopragmatic analysis is innovative. In the course of the study, an attempt was made to establish the relationship between the type of rhyme and the way of musical arrangement of the text. For poetic texts with a cross rhyme, there is a tendency to use repetitions of the melody in accordance with the rhyme. Texts with a more complex rhythmic organization of the verse are decorated with variations or author’s reworking of the original melody. At the same time, the processing of musical material obeys the generally accepted patterns of melody development within the range of one octave. With a more detailed analytical review, different types of ways of using the original melodies and adapting them to the needs of choral church singing can be identified. The determining factor in the choice and interpretation of the original folk melody is the text of the psalm. Melodies do not have independence, but are completely subordinated to the verbal text. At the same time, the musical arrangement serves as an auxiliary means of accentual articulation and enhances the aesthetic function of the poetic text.

The article focuses on the concept of time in human and global perspective in the poetry of two Swedish authors of the 19th century: Per Atterbom and Viktor Rydberg. These two poets belong to different branches of the Romantic movement. Atterbom represents the early mystic Romanticism and he is one of the first Romantic authors in Sweden. Rydberg is a post-Romantic poet: his poetic works contain features that are characteristic of the literature of Romanticism, but they were written in the last decades of the century. The theme of the power of time is one of the most important for both authors, it determines characters of lyrical heroes and poetics in many of their poems but in different ways. Atterbom represents the destructive power of time. Thus, the main characters of his fairy tale play “The Isle of Bliss”, Hyperborean king Astolf and nymph Felicia, live on a magical island and aspire to escape from Time, but Time overcomes them. Atterbom shows in his poetry that time hasn’t its limits in the world beyond. Rydberg represents the characters who try to apprehend the rules of time. The immortal mythological creatures in his poems (the Tomten, the elf of a river) cannot explain why time has such an influence on man and mankind. This theme corresponds with a philosophical matter of the meaning of human life. The humans in Rydberg’s lyrics do not try to overcome time as they perceive the nature and its rules throw their senses.
Christian Morgenstern and Henrik Ibsen (an episode in the history of literary translation)

This article discusses the history of creative contacts between the great Norwegian playwright Henrik Ibsen and the German poet Christian Morgenstern (1871–1914). Christian Morgenstern’s life was short and marred by physical suffering, but fantastically full and diverse in creative terms. A significant part of Christian Morgenstern’s lyrical and epistolary legacy was published only after his death thanks to the efforts of his wife and friends. Christian Morgenstern’s translations of Henrik Ibsen’s works date from the late 19th century, when the new Solomon Fischer’s publishing house (S. Fischer Verlag) in Berlin decided to publish the complete works of Ibsen in a translation into a German language that would be worthy of the original language. The publishing house turned to a young and at the time still little known poet who, being in love with Scandinavian literature and with Henrik Ibsen, set to work with great enthusiasm, settled in a family boarding house near Christiania, in a short time learned Norwegian, consulted and corresponded with Ibsen several times and as a result created translations for his plays, the German of which was delighted and earned the high praise of the playwright. An authorized edition of the translations was printed in Germany between 1898 and 1904 and is now a bibliographic rarity. However, many of Ibsen’s works are still published in Germany in the translation of Christian Morgenstern, known primarily as an unsurpassed master of poetic miniatures in a unique style of lyrical humor.
Pieter Quast’s drawings in the collection of the State Hermitage Museum

The article analyses five drawings by the Dutch painter Pieter Quast (circa 1606– 1647) from the collection of the State Hermitage Museum. The sheets shown are unpublished. They are executed in the artist’s characteristic technique: in black chalk on vellum; some sheets are signed and dated. They come from three different collections, four of the drawings came into the museum in the 18th century and one is a late acquisition and was purchased in 1972. The little-known master’s diverse body of work is represented in museum collections and private collections mainly by graphic material, including numerous drawings. The artist’s passion for drawing seems to have also been caused by his poor financial situation. Although Quast’s biography is known in fragments, published archival materials reveal the artist’s complex creative path. A study of his works from the national collection confirms their authorship and gives grounds for speculation about the reading of the subjects. The themes chosen by the master are inextricably linked with the pictorial tradition: the work of the 16th century masters, in particular Pieter Bruegel the Elder, and Quast’s contemporaries Adriaen Braouwer, Adriaen van Ostade and others. The artist relied heavily on theatrical representations, both biblical and humorous folk sketches, as an important source of inspiration. This research paper analyses the master’s drawings both in terms of iconography and using the formal and stylistic method, using comparative analysis and putting the works in line with the artist’s other famous works.
Alexander Kuchin (1888–1913?) and his Small Russian- Norwegian dictionary

The article introduces Alexander Kuchin and his “Small Russian-Norwegian dictionary”, which was published in 1907 by the publishing house “Pomor” (Finnmarken) in Vardø (Norway) and was very popular at that time. Its author, Alexander Stepanovich Kuchin, a man with a unique destiny, is known to compatriots as the only Russian who participated in the discovery of the South Pole in the Roald Amundsen’s expedition, and also as the first of our countrymen who, after the discovery of Antarctica in 1820 by the expedition of Faddey F. Bellingshausen and Michael P. Lazarev, landed on the coast of the Southern continent. A talented young man who died in the expedition of Vladimir A. Rusanov at the age of only 25, made a great contribution to science, research and navigation. Born in the village of Kushereka in the Onega district of the Arkhangelsk province, Alexander received a good education for that time. He graduated from a two-grade parochial school in Kushereka, brilliantly studied at the Onega City School, attended classes at the Tromsø school for a year and was the only one in the course graduated from the Arkhangelsk Merchant and Maritime School with a gold medal. He read H. Ibsen, K. Hamsun, J. Falkberget and other writers in the original. Alexander was also lucky to work at the biological station in Bergen under the direction of Bjørn Hjelland-Hansen, one of the founders of oceanography as a science; here he also met Fridtjof Nansen, one of the national Norwegian heroes, which played a significant role in A. Kuchin’s life. The “Small Russian-Norwegian dictionary” was published in 2,000 copies and was very popular that time. The dictionary contains around 4,000 words on 48 pages. There are no proper names in it, but at the end of the dictionary basic information about the phonetics and grammar of the Norwegian language is disposed. It is focused on Russian users and arouses undoubted interest among linguists, since it appeared in 1907, two years after the termination of the union with Sweden. It is valuable that Alexander Kuchin, not being a linguist, fixed the language used by common people such as fishermen and trawlermen in the North of Norway (particularly in Finnmark and Troms). Such a democratic version of the language is also of special scientific interest. In general, the dictionary was caused by necessity, appeared at a proper time, was well compiled and completely fulfilled the functions assigned to it.
Developing and testing a web-based platform for visualizing flow in a watershed

Thanks to the rapid development of internet technology and computer hardware, it is now possible to use web services to provide visual simulations of flow field calculation results. Visualization technology can display complex water flow data and the laws that govern water flow through graphical means, and can be used to solve scientific and engineering problems related to water conservancy. In this study, we developed a platform for visualizing flow in a watershed based on a Cesium rendering framework with Browser/Server (B/S) architecture that used isosurface, particles, texture-based, and dynamic flow visualization techniques to visualize scalar field, vector field, and dynamic flow field data. Furthermore, our performance test results indicate that the rendering performance meets the practical application requirements for visualizing large-scale flow fields by employing frame interpolation and viewpoint-based dynamic rendering techniques. The results from testing the water flow visualization platform in the Beijiang River Basin, Guangdong Province, China, demonstrated that the platform performed well on different devices and that the running frame rate reached 50–60 fps. These findings can be used to guide further development and applications of web-side flow field visualization technology.
An Extra-articular Ganglion Cyst with Multiple Fluid-fluid Levels

Published: August 2023

Introduction:

Ganglion cysts are the knee�s most common benign soft tissue tumors. Ganglion cysts are seen as multiloculated fluid collections on magnetic resonance imaging (MRI), and fluid-fluid levels are not an expected finding.

Case Presentation:

A 36-year-old female patient presented with swelling in her right knee. Magnetic resonance imaging revealed a multiseptated cyst with multiple fluid-fluid levels within the anterior of the right patellar tendon. Open surgical excision was performed, and the pedicle of the cyst was dissected. The histopathology revealed a ganglion cyst with hemorrhage.

Conclusion:

The ganglion cysts should be considered in the differential diagnosis of lesions with fluid-fluid levels, in addition to hemangioma, synovial sarcoma, and aneurysmal bone cysts of soft tissues.
