Published: June 2022

Abstract: Understanding what cyber security is and how to successfully apply it in today's culture, which is driven by technology and network connections, is vital. Systems, essential information, data, and other important virtual goods are at risk if there is no security to protect them. Every business, whether it is an IT firm or not, requires equal protection. Similarly, attackers do not lag behind in terms of developing new cyber security technology. They've upgraded their hacking techniques and are concentrating on the weak places of several businesses. Cyber security is vital because military, political, financial, medical, and corporate entities gather, practise, and store large amounts of data on PCs and other devices. Financial data, intellectual property, personal information, and other sorts of data that could be harmed by unauthorised access or acquaintance can make up a major amount of the data

Assessment of inflation expectations based on internet data
Authors:   RANEPA, Moscow, Russian Federation, Petrova Diana
Published: June 2022

This article provides assessments of inflation expectations of Russian internet users based on the posts of the social media Vkontakte and Google Trends search queries during 2014–2021. We collect posts from news communities and search queries to measure inflation expectations using inflation‐related regular expressions. Inflation expectations based on internet data are highly correlated with actual inflation and reflect household concerns about price increases during 2014–2021. Granger causality tests have shown both measures of internet user inflation expectations can be potential predictors of actual inflation. An econometric analysis of the New Keynesian Phillips Curve is carried out using VAR from February 2015 to December 2021. The results suggest that an increase in inflation expectations is consistent with an increase in actual inflation and a tightening of monetary policy.

Authors:   Aristotle University of Thessaloniki, Greece, Fousekis Panos , Tzaferi Dimitra ,   Aristotle University of Thessaloniki, Greece
Published: June 2022

This work investigates price multifractality and informational efficiency in the futures markets of the US soybean complex (soybeans, soybean meal, soybean oil, and the crush spread) using daily prices from 2015 to 2021 and Multifractal Detrended Fluctuation Analysis (MFDFA). The empirical findings suggest: First, none of the four series exhibited long-range dependence. They did, however, show considerable serial dependence locally. The futures prices of soybeans and soybean oil, and of the crush spread were locally anti-persistent (persistent) for large (small) fluctuations whereas the futures prices of soybean meal were persistent for all small and large fluctuations. Second, all markets in the US soybean complex exhibited some degree of informational inefficiency with that of the crush spread being less efficient relative to the other three. Overall, the results provide valuable information to investors as to whether trend-following or oscillatory trading strategies are more appropriate.

Authors: AKINYEMI OLUWASEGUN , Abodunrin Faith , Lipscombe Christina , Nasef Kindha Elleissy , Aaron Sabrina , Fakorede Mary , Anju Ranjit
Published: June 2022

Objectives: To determine if race/ethnicity is an independent predictor
of adverse outcomes following diagnosis of primary ovarian cancer.
Design: Retrospective study Setting: We utilized data from the
Surveillance, Epidemiology, and End Results Program (SEER) database for
this study. Population: We studied women with a primary diagnosis of
Ovarian Cancer in the SEER database between January 1998 and December
2018. Method: We utilized the nearest neighbor propensity-score matching
without replacement in a 1:1 ratio to compare mortality and overall
survival following primary ovarian cancer diagnosis between Non-Hispanic
Black (NHB) women and a control group of Non-Hispanic White (NHW) women.
These women were matched for age, treatment modalities
(surgery/irradiation/chemotherapy), laterality, and stage of cancer at
presentation. Main Outcomes: The primary outcomes of interest were
differences in mortality and survival (in months) among NHB and NHW
women Results: We compared 6,801 NHB women with 27, 204 NHW women with
primary ovarian cancer. Prior to propensity-score matching, NHB women
had a higher mortality rate (56.7%vs.53.5%, p<0.001) and
lower survival rate (40.1 vs. 48.9 months<0.001). Following
propensity-score matching, there was no difference in the mortality rate
between the two groups. (56.7% vs 55.7% p=0.13). However, NHB women
had significantly lower survival rates (40.1vs.49.6 months, p
< 0.001). Conclusion: Racial disparities in survival following
treatment for ovarian cancer persist despite adjusting for age, stage of
cancer, and treatment modalities. Further research is warranted to
explore patient and systemic factors such as appropriate level of care
and follow-up after treatment that might account for these differences.
Mathematical modelling of respiratory viral infection and applications to SARS-CoV-2 progression
Authors: Mahiout Latifa Ait , Bessonov Nikolai , Kazmierczak Bogdan , Volpert Vitaly
Published: June 2022

Viral infection in cell culture and tissue is modeled with delay
reaction-diffusion equations. It is shown that progression of viral
infection can be characterized by the viral replication number,
time-dependent viral load and the speed of infection spreading. These
three characteristics are determined through the original model
parameters including the rates of cell infection and of virus production
in the infected cells. The clinical manifestations of viral infection,
depending on tissue damage, correlate with the speed of infection
spreading, while the infectivity of a respiratory infection depends on
the viral load in the upper respiratory tract. Parameter determination
from the experiments on Delta and Omicron variants allows the estimation
of the infection spreading speed and viral load. Different variants of
the SARS-CoV-2 infection are compared confirming that Omicron is more
infectious and has less severe symptoms than Delta variant. Within the
same variant, spreading speed (symptoms) correlates with viral load
allowing prognosis of disease progression.
Cylindrical Screen to Study Transmission Grating and Reflective Grating Experiments
Authors: Peng Hui
Published: June 2022

The gratings contain transmission gratings and reflective gratings. The
textbook-screen in the grating experiments is a planar screen. To study
the orientation-dependence of the 2-dimention diffraction patterns of
the grating, we proposed the cylindrical screen. Then utilizing the
cylindrical screen in both transmission grating experiments and
reflective grating experiments. Experiments show the 2-dimention curved,
expanded and inclined diffraction patterns. The cylindrical screen
visually shows that the diffraction orders of the rotating gratings
distribute in two dimensions. The CCD can be placed at the precise
locations of each order to collect data. By using the cylindrical
screen, two coordinates are needed to describe the curved, expanded and
inclined diffraction patterns of the rotating grating. The cylindrical
screen may be used to test the theories of the grating rotating around 3
axes.
Selected lipopeptides of Bacillus as plausible inhibitors of SARS-COV-2 chymotrypsin-like protease 3CLPro: an in-silico analysis
Authors: Sen Samya , Banerjee Saikat , Ghosh Atreyee , Sarkar Keka
Published: June 2022

A coronavirus disease pandemic caused by the novel severe acute
respiratory syndrome virus-2 or nCoV-2 has escalated to a global health
emergency. In search of prospective therapeutics against the virus from
the microbial treasure trove, three classes of cyclic lipopeptides
produced by the bacterial genus Bacillus, namely Surfactins,
Fengycins, and Iturins, were chosen as exploitative targets against the
main viral protease, 3CLPro, in turn, responsible for the ordered
transcription and replication of the virus. On performing molecular
docking analysis using AutoDock Vina, all the annotated lipopeptides
showed promising binding stability, ranging from -6.1 to -7.4 kcal/mol,
compared with the control inhibitor Darunavir (-7.2 kcal/mol). The
lowest binding energy was observed for Fengycin 35518574 whereas the
highest was for Surfactin B, but due to the richness in forming
effective interactions with the target, Surfactin C was adjudged the
most potent among all others. Molecular dynamics simulation analysis
using iMODs server strengthened our claim that the 3CLPro-Surfactin C
complex was stable, based on Deformability, Bfactor, Eigenvalue,
Covariance, and Elastic network modeling. All the lipopeptides were
found to form multiple hydrogen-bonded and hydrophobic interactions with
the enzyme, in-silico, due to the exposed polyhydroxyl moieties
and prenyl groups in their peptide structures. As most of these
lipopeptides are non-toxic to human cells, the results of this study
emphasize the need for research using these wonder molecules and their
derivatives as pharmaceuticals in combating notorious viruses like
nCoV-2.

Beton, dünyada en çok kullanılan yapı malzemesidir. Ancak çimento üretimi sırasında yüksek miktarda enerji tüketilmekte ve karbondioksit salımı yapılmaktadır. Çimentoya alternatif bağlayıcıların üretilmesi, uzun süredir üzerinde çalışılan bir konudur. Geopolimerler, çimentoya alternatif olma potansiyeli taşıyan malzemelerdir. Geopolimerlerin iyi bir yüksek sıcaklık direncine sahip oldukları bilinmektedir. Ancak hem geleneksel hem de geopolimer betonların yüksek sıcaklık dirençleri, kullanılan agreganın türü ve özelliklerinden önemli ölçüde etkilenmektedir. Bu çalışmada kireçtaşı, dere, bazalt ve cüruf agregaları kullanılarak üretilen geopolimer betonların 600 ve 900°C yüksek sıcaklık etkisine karşı dirençleri basınç dayanımı kayıpları kıyaslanarak tespit edilmiştir. 900°C sıcaklık etkisinde, kireçtaşı ile üretilen geopolimer beton tamamen parçalanırken dere, bazalt ve cüruf agregaları ile üretilen betonların %32.9, 48.5 ve 53.6 oranında basınç dayanımı kaybına uğradıkları tespit edilmiştir.

Type I myocardial infarction (T1MI) is caused by acute atherosclerotic plaque disruption; in contrast, type 2 myocardial infarction (T2MI) is caused by changes in myocardial oxygen supply or demand in the absence of acute atherothrombosis [1]. T2MI was initially introduced as part of the universal definition of MI (UDMI). It refers to individuals with an increased cardiac troponin (cTn) level but no evidence of ischemic etiology. Most doctors are baffled by the word, and the definition remains inadequate. It’s not TIMI with evidence-based therapy and guidelines, but rather peer review based. Is chest discomfort accompanied by decompensated heart failure, acute anemia, and Pulmonary embolism indicative of myocardial ischemia? Is transitory ST depression a marker of myocardial ischemia in individuals with fast AF, anemia, sepsis, or electrolyte disturbances? The answer to all these questions is unknown or is currently being determined. On the other hand, is it prudent to do coronary angiograms for all patients? While the answer is still uncertain, the response is emphatical NO. Most doctors use clinical judgment.

Durante os estudos de resolução de questões matemáticas, é comum o professor ser indagado por perguntas como: ‘Essa conta é de vezes ou é de dividir?’, ‘Diz que ele dividiu, então é de dividir?’, ‘Está escrito que ela triplicou, então a conta é de multiplicar?’. As respostas dadas pelo professor nem sempre satisfazem a necessidade do estudante. Esse artigo traz os resultados de uma pesquisa de doutoramento em que foram analisadas questões aditivas, questões multiplicativas e questões socioeducacionais. Para esse artigo, foi realizado o recorte para a análise das questões multiplicativas, e o objetivo foi analisar se a habilidade de escolha da operação em questões multiplicativas que envolvem números decimais está associada estatisticamente à habilidade de escolha da operação em questões multiplicativas que envolvem números naturais. Para atingir esse objetivo, optou-se pelo uso de testes como instrumento metodológico de pesquisa para nortear a investigação e a análise estatística realizada por meio do teste de associação Qui-Quadrado. Os resultados indicam que se o estudante escolher corretamente a operação em questões multiplicativas com números naturais, tanto aritméticas quanto algébricas, ele tende também a escolher corretamente a operação em questões multiplicativas com números decimais, tanto aritméticas quanto algébricas.

The researchers performed this systematic review to offer insights into the trend of the corpus-based approach in studying metaphor in recent years and investigate the potential gaps and under-researched areas in the past literature on the topic. Two research databases, namely Google Scholar and Academics, were explored to collect data. The analysis of metaphor-related research studies published between 2015 and 2020 revealed more than 78 studies dealing with the topic of investigation. After the screening process, 23 studies that met the research criteria were retained for analysis. The selected articles were further analyzed using the two-step analysis involving quantitative and qualitative approaches, i.e., descriptive statistics, and thematic analysis. The findings revealed that metaphor studies employing the corpus approach tend to use existing corpus like the Reference Corpus instead of a specialized corpus. In addition, metaphor studies in this review centered more on written discourse than spoken data. Furthermore, there is also a lack of information on the corpus tool employed in the examined studies. Meanwhile, the thematic analysis unearthed potential gaps and under-researched areas, such as limited studies on COVID-19 metaphor even though the outbreak had started at the end of 2019. Future studies on this research could include more specialized corpora, specifically in the under-researched topics, to fill in the gaps in this area of study
Technological Progress, Artificial Intelligence Development and Ethical Paradigms

In the historical landscape, technological discovery and development have significantly impacted human life, individually and communally. The significant impact of technological development is positive or negative depending on the influence of human vision, plans, strategies, and implementation on the design of these technological developments. Given that human-technology relations are symbiotic in the sense that it is affecting each other, or furthermore along with human-nature relations which make triadic symbiosis, ethics has a crucial role in maintaining humanity level and the stability of life, including the anticipation that technology will not become a disaster in the future. This research seeks to analyze the artificial intelligence (AI) development in Indonesia, one of the developing countries with a high level of attention to technological development, by offering an ethical paradigm as its basis. This paradigm is based on three principles, namely, (1) responsibility, (2) awareness, and (3) sustainability. Against the historical-philosophical backdrop of the technological development in human life and its relationships and possibilities, the offer of the ethical paradigm is intended to be the basis for the design of AI vision, strategy, and implementation as management of all the impacts of AI development, including the positive potential.

The article studies and conceptualises alarmism and eschatology in the modern Ukrainian discourse. The approach to understanding the concept developed by G. Frege (“Fregean Thoughts”) was used as the theoretical basis for conceptualising these categories. The research interest of the paper is caused by the identification of the content of the conceptual levels of alarmism and eschatology. The results make it possible to define alarmism as a worldview sensation of an intuitive level that historically emerged from empiricism, reflecting the readiness to overcome the current global challenges. Eschatology arises as a doctrine that accepts the finiteness of individual and universal beings. The conceptualization of alarmism and eschatology allows us to conclude that, although both categories act as a means of characterizing the state of modern global society that has lost its intentions for its development, eschatology is looking for ways to reconcile with the inevitable approaching of “end of history”; the alarmism tries to mobilize the efforts of the global society to overcome the acute challenges of our time, gives one or another problem the status of serious.
