Тайны «перестройки»
Authors: Ильинский Игорь Михайлович
Published: July 2023

Статья известного социального философа, ректора Московского гуманитарного университета И. М. Ильинского представляет собой вариант текста главы в книге о «перестройке»,  над которой автор работает уже многие годы. Данный текст продолжает тему предыдущей статьи И. М. Ильинского, опубликованной в журнале «Знание. Понимание. Умение» (2023.  № 1). Автор развивает свою аргументацию относительно того, что, согласно представленным им фактам, «перестройка» была именно заговором высших лиц государства против советской общественной и политической системы. Опираясь на исследования советского государственного деятеля Н. И. Рыжкова, автор показывает, что реально «перестройка» началась еще в период правления Ю. А. Андропова (1983), однако радикальный характер она приняла во второй половине 1980-х гг. И, как обосновывается в статье, в своем радикальном варианте «перестройка» воплощала замысел вовсе не к улучшению социализма в СССР, но, напротив, была подчинена задачам разрушения советской «системы». При этом «прорабы» «перестройки» в лице Горбачева, Яковлева и Шеварднадзе опирались в своих намерениях на многочисленный слой советской интеллигенции, при игнорировании реальной воли населения страны, которая была прежде всего выражена на референдуме 1990 г. В то же время, как показывает Ильинский, советский народ не мог выразить более сильного протеста против развала страны, поскольку люди были погружены в повседневные нужды, перегружены политической информацией, подавлены быстротой происходящих изменений и т. д. Однако при всех этих обстоятельствах, как показали социологические исследования, данные которых приводятся в статье, на самом деле население СССР на рубеже 1980–1990-х гг. предпочитало в большинстве своем социализм капитализму.
Антропонимические герои в современном пространстве коммуникации
Authors: Завьялова Наталья Алексеевна
Published: July 2023

Работа является частью исследовательской программы по изучению особенностей функционирования единиц языка в условиях современной культурной коммуникации. Цель работы — разработка методики изучения прецедентных антропонимов, значимых для массового сознания представителей различных культур и цивилизаций. На материале русского, китайского и английского культурных кодов исследуется антропоним «Карлсон».

         Антропоним описывается с позиции синхронии и диахронии. Важной чертой антропонима является то, что он не потерял своей актуальности для постсоветской России и благополучно мигрировал из советских анекдотов в современную действительность. В статье предпринята попытка уточнить терминологический аппарат, наряду с отечественными терминами приводятся актуальные для международной науки термины на английском языке. Авторами разработана комплексная методика описания антропонима с привлечением материала электронных онлайн-корпусов, системы поиска семантически связанных слов «Серелекс», оценкой качества аудиовизуального перевода.

Сформированная в ходе исследования модель представляет собой следующие этапы: монолингвальный контент-анализ примеров с антропонимом из лингвистических корпусов, словарей; полилингвальный контрастивный контент-анализ примеров с антропонимом из лингвистических корпусов, словарей; анализ частотности антропонима и семантически близких лексем, их кластеризация в монолингвальном и полилингвальном сопоставительном режиме; антропоним в экстралингвистическом пространстве (описание артефактов, использующих антропоним, транслируемый им образ); степень популярности антропонима в пространстве электронной коммуникации; инварианты перевода антропонима в аудиовизуальной среде; анализ функциональной социолингвистической направленности контекстов с антропонимом; описание функционирования антропонима в синхроническом и диахроническом аспектах.

Результаты исследования могут найти свое применение в комплексе современных наук, фокус которых направлен на важные особенности и законы электронной коммуникативной среды.
Slip Deficit Rates on Southern Cascadia Faults Resolved with Viscoelastic Earthquake Cycle Modeling of Geodetic Deformation
Authors: Materna Kathryn , Murray Jessica R. , Pollitz Fred , Patton Jason R.
Published: July 2023

The fore-arc of the southern Cascadia subduction zone (CSZ), north of the Mendocino triple junction (MTJ), is home to a network of Quaternary-active crustal faults that accumulate strain due to the interaction of the North American, Juan de Fuca (Gorda), and Pacific plates. These faults, including the Little Salmon and Mad River fault (LSF and MRF) zones, are located near the most populated parts of California’s north coast and show paleoseismic evidence for three slip events of several-meter scale in the past 1700 yr. However, the geodetic slip rates of these faults are poorly constrained. In this work, we analyze a new compilation of interseismic geodetic velocities from Global Navigation Satellite Systems, leveling, and tide gauge data near the MTJ to constrain present-day slip deficit rates on upper-plate faults and coupling on the megathrust. We construct Green’s functions for interseismic slip deficit for discrete faults embedded in an elastic plate overlying a viscoelastic mantle. We then use a constrained least-squares inversion to determine best-fitting slip rates on the major faults and investigate slip rate trade-offs between faults. Results indicate that the LSF and MRF systems together accumulate 4–5 mm/yr of reverse-slip deficit, although their separate slip rates cannot be determined independently. Modeling of the horizontal and vertical velocities suggests that the southernmost CSZ is coupled interseismically to deeper than 25 km depth. We also find that 6–17 mm/yr of right-lateral slip deficit extends north of the MTJ and into the southern Cascadia fore-arc. These results reinforce the notion that both the southernmost Cascadia megathrust and the smaller fore-arc faults above it contribute to regional seismic hazard.
Combining Seismotectonic and Catalog-Based 3D Models for Advanced Smoothed Seismicity Computations
Authors: Pandolfi Claudia , Taroni Matteo , de Nardis Rita , Lavecchia Giusy , Akinci Aybige
Published: July 2023

The new generation seismic hazard maps use 3D seismotectonic fault models, which are more consistent with the actual nature of faults, whereas the classical models based on earthquake catalogs only utilize a 2D representation of the seismicity. Although the former provides more reliable information on seismogenic structures, the latter can deliver trustworthy seismicity rates easily. Therefore, it is necessary to combine both the approaches to create a high-quality seismic hazard assessment model. This study proposes an innovative approach using smoothed seismicity methods that can be advantageous in all contexts with available 3D fault models and high-quality seismic catalogs. We applied our method on the Adriatic Basal Thrust (ABT) in eastern central Italy—a lithospheric-scale active contractional structure with a well-constrained 3D geometric–kinematic reconstruction and a related high-quality catalog. Our new 3D algorithm was applied to smooth the ABT seismicity on the grid, resulting in a 3D earthquake rate model that also provides rupture parameters such as strike, dip, rake, and seismogenic thickness. Our approach is particularly useful for complex seismotectonic settings, such as in cases of lithospheric shear zones, subduction planes, and overlapping multidepth seismogenic volumes.
INVESTIGATION OF SOLUTION RECOMMENDATIONS DEVELOPED BY TEACHER CANDIDATES ON DIGITAL ADDICTION SCENARIOS
Authors: ÖZER ŞANAL Seda , TORUN Fulya , DARGUT GÜLER Tülay
Published: July 2023

Digital addiction, which negatively affects the physical and psychological health of individuals and gradually spreads to different areas, is a problem that needs to be resolved for all organizations that care about individuals. Understanding, solving and developing interventions to reduce this problem is critical for a healthy social culture at macro scale and for the life of a healthy individual at micro scale. Digital addiction is a situation that can be seen in all areas of life and in all age groups. In this study, digital addiction scenarios were produced by wondering how digital addiction can be solved from the perspective of teacher candidates. It has been possible to evaluate the awareness, knowledge and competencies of the pre-service teachers with the solution suggestions they brought to the digital addiction scenarios. The solution suggestions produced by the pre-service teachers for the addiction problem of a digitally addicted student were gathered under the themes of detection, intervention and support, domestic arrangements, information and awareness raising, socialization and communication, and follow-up and observation. After the thematic analysis of these solution proposals, themes and sub-themes were created and the themes were discussed in the light of the literature.
Vaginal delivery in a patient with asymptomatic severe aortic stenosis: a case report
Authors: M. Kanagavarshani , Kaur Amanjot , Sikka Pooja , Aggarwal Neelam , Chopra Seema
Published: July 2023

Heart disease complicates about 1-4% of all pregnancies of which valvular heart disease is the commonest cause. In developing countries, congenital heart diseases are commonly first detected during pregnancy. Most women do well during pregnancy but severe mitral stenosis or severe aortic stenosis are high-risk conditions that can cause significant morbidity and mortality. Unlike asymptomatic severe mitral stenosis, asymptomatic severe aortic stenosis is mWHO category 3. There is no consensus on the mode of delivery in patients with asymptomatic severe aortic stenosis. Here we describe a case of successful vaginal delivery in a woman with severe aortic stenosis. As the patient was asymptomatic and ejection fraction was preserved, a joint decision for vaginal delivery was taken along with the cardiology team. The patient was induced and delivered with operative vaginal delivery. This case shows that vaginal delivery could be a viable option in patients with asymptomatic severe aortic stenosis given continuous haemodynamic monitoring can be provided.

Aim. Comparative study of the source material of four populations of Sedum roseum (L.) Scop. belonging to different ecological and geographical zones of origin and assessment of their suitability for cultivation in the conditions of the non‐chernozem zone of the Russian Federation.

Materials and methods. The following populations were studied: the cultivated population of VILAR (Altai, 1980), the cultivated population of the Botanical Garden of Pitirim Sorokin Syktyvkar State University (Syktyvkar, Komi Republic), an introduced population from Kirovsk, N. A. Avrorin Polar‐Alpine Botanical Garden‐Institute and a cultivated population of Innsbruck Botanical Garden, Austria.

Results. Morphological description of the samples was carried out and the productivity of raw materials and seeds and the main biological and karyological features of the populations studied were determined. The results of made it possible to identify Rhodiola populations characterized by high winter hardiness (A and D) and low winter hardiness (B and C). A high productivity of roots and rhizomes in the fourth year of life in populations C and A (30–31 g) was established, and in terms of the content of active substances (phenylpropanoids) in population B (Komi) – 5.4%. The numbers of chromosomes (2n=22) were determined and their morphometric analysis was carried out and formulas of karyotypes of the Rhodiola populations studied were compiled. Chromosomal analysis using C/DAPI‐differential staining showed that no chromosomal abnormalities were detected in the karyotypes, which indicates their stability.

Conclusion. Morphological variability indicates the ecological plasticity of the populations studied, which indicates the prospects for their field cultivation.

El alambrado de campos de uso común ha servido históricamente para perpetrar el despojo. El objetivo de este artículo es comprender las disputas y la producción de sentidos y prácticas de defensa de la tierra-territorio en el movimiento campesino de Santiago del Estero y en el campo burocrático en torno a la categoría cercar, a partir de las experiencias de los encierros ganaderos comunitarios en dicha provincia argentina. En situaciones etnográficas diversas, pudimos observar las formas de (des)legitimar visiones y procedimientos desplegados en la defensa legal de la tierra. Por un lado, la del mocase Vía Campesina, nucleados alrededor de la consigna de “no cercar”, asociada al concepto de “territorio”. Por otro, la que considera viable el “cercamiento” como estrategia de resistencia sustentada en el marco jurídico del derecho posesorio y lógicas económico-productivas promovidas por técnicos y funcionarios en el marco de una política pública nacional.

Introduction This paper evaluates the Alliance 16 (A16) collaborative led by Emergency Care Implementation Support Team (ECIST) during 2021, which had the aim of reducing in hospital length of stay (RiHLOS). A16 was a centrally funded programme managed collaborative, with sixteen sites selected for inclusion through regional nomination from each of the seven regions. The work focused on measures to improve patient discharge from hospital and length of stay. Evaluation of any measures on this scale is relatively complex due to the heterogeneity differences of the hospital sites, clinical areas involved, and improvement measures selected by sites.
The Gravity Model of Trade: The Case of Central and Eastern Europe
Authors: Lypko Nazarii
Published: July 2023

The main patterns of international trade in the countries of Central and Eastern Europe have been analysed in the paper. The gravity model, estimated for a large sample of bilateral trade flows for the analysed states, has been used as a benchmark. The model has been updated according to the modern conditions in the international economy. The emphasis has been made on the analysis of products' trade since the trade of services requires separate modelling. The purpose of the paper was to find the main factors that determine gravity trends in international trade in Central and Eastern Europe. It has been proven that the distance between countries and their gross domestic products are still crucial factors which determine trade flows between them. Additionally, the influence of the product structure of export has been considered. A higher share of value-added export increases bilateral trade between the countries. Common past for the analysed countries boosts trade between them because of the presence of historical trade traditions and the development of regional production agglomeration. It has been proven that the gravity equation remains a simple and reliable model of the factors which determine the trade between countries.

Povzetek. V prispevku so analizirani glavni vzorci mednarodne trgovine v državah srednje in vzhodne Evrope. Kot merilo je bil uporabljen gravitacijski model, ocenjen za velik vzorec dvostranskih trgovinskih tokov analiziranih držav. Model je bil posodobljen glede na sodobne razmere v mednarodnem gospodarstvu. Poudarek je bil na analizi trgovine z izdelki, saj trgovina s storitvami zahteva ločeno modeliranje. Namen prispevka je bil ugotoviti glavne dejavnike, ki določajo gravitacijska gibanja v mednarodni trgovini v Srednji in Vzhodni Evropi. Izkazalo se je, da sta razdalja med državami in njihov bruto domači proizvod še vedno ključna dejavnika, ki določata trgovinske tokove med njimi. Poleg tega je bil upoštevan tudi vpliv strukture izdelkov pri izvozu. Večji delež izvoza z dodano vrednostjo povečuje dvostransko trgovino med državami. Skupna preteklost analiziranih držav spodbuja trgovino med njimi zaradi prisotnosti zgodovinskih trgovinskih tradicij in razvoja regionalnih proizvodnih aglomeracij. Dokazano je bilo, da gravitacijska enačba ostaja preprost in zanesljiv model dejavnikov, ki določajo trgovino med državami.

Published: July 2023

The implementation of smart energy systems (SES) in the Slovenian energy sector has raised significant privacy and data protection concerns. The collection and processing of personal data from energy consumers, as well as cybersecurity threats, pose risks that must be addressed. The legal framework governing privacy and data protection in the energy field in Slovenia is based on the GDPR, ZOEE, ZVPot-1, ZVOP-2 and others, which impose significant obligations on entities processing personal data. To mitigate these risks, exact terminology must be used to implement privacy, data protection and also cybersecurity measures and ensure compliance with the legal framework.
The Right to a Fair Trial of Legal Persons Throughout the Case Law of the ECHR and the CJEU
Authors: Sokolova Mariia
Published: July 2023

The ambition of this article is an analysis of the right to a fair trial of legal entities through the prism of the jurisprudence of the ECtHR and the CJEU. Despite the factual admission of the right to a fair trial to companies in the case law of the Courts, the absence of a strong theoretical foundation and persuasive explanation in their judgments raises ambiguity as to the ECtHR and the CJEU positions in that regard. In that context, the article examines landmark cases of both Courts and relevant doctrinal considerations concerning the application of guarantees provided by the right to a fair trial to legal persons. The ECtHR case law is considered inconsistent and the Strasbourg court, it appears, tries to avoid any far-reaching conclusions. The CJEU in its case law, due to the inherent focus of EU law on economic values, interprets the right to a fair trial of companies broadly, and sometimes, broader than it is needed. It is concluded that the issue requires more attention from both the Courts and legal scholars, in the view of serious consequences the ignorance and unfounded admission of any fundamental right could entail to the society and economy.

Aim: To evaluate the prevalence and factors associated with gummy smiles in adolescents aged between 15 and 18 years attending high school. Methods: The cross-sectional and quantitative study was carried out during the Covid-19 pandemic, with 160 adolescents, from two public (A1) and two private (A2) schools chosen by lottery, divided into two groups: G1 (with gummy smile) and G2 (no gummy smile). A clinical examination was carried out on the adolescents, investigating the presence or absence of a gummy smile (GS), by analyzing the variables (interlabial distance at rest, upper incisor exposure at rest, smile arc, measurement from the subnasal to the upper lip philtrum, upper lip length, upper lip thickness, hypermobility and lower/middle third ratio). Means and dispersion were obtained, and the Chi-square association test was applied, to compare the results between A1 and A2 and between G1 and G2. Results: The prevalence of GS was 33.8% (=54). It was found that no statistically significant associations were found (p > 0.05), regarding the type of school and gender with the presence of GS in adolescents. There was no statistically significant difference (χ² = 1.82; p = 0.07) between the groups and the age of adolescents. There was a significant association between the studied variables and GS (p < 0.05). Conclusion: The prevalence was high with a predominance of females. There were no statistically significant associations regarding the type of school and gender, but there was a significant association between gummy smile and lip dimensions.
Influence of medium-translucency monolithic zirconia thicknesses and light-curing time on the polymerization of dual-cure resin cements
Authors: Jamel Raghad S.
Published: July 2023

Aim: To investigate and compare the effects of different thicknesses of medium-translucency monolithic zirconia and light curing times on the polymerization of two types of dual-cured resin cement. Methods: A total of 200 cement specimens were prepared from TheraCem and RelyX U200 cement. The specimens were divided into 5 groups: Group I, without interposing zirconia; Group II, 0.50 mm thickness; Group III, 1.00 mm; Group IV, 1.50 mm; and Group V, 2.00 mm thickness. Each group was subdivided into (1) RelyX U200 and (2) TheraCem. Each subgroup was subdivided according to the light-curing time into (a) 20 s and (b) 40 s (n =5). The polymerization was tested using Fourier-transform infrared (FTIR) spectroscopy and a Vickers microhardness tester. The data were statistically analyzed using ANOVA, an independent sample t-test, and Tukey’s test at a significance level of 0.05. Results: The control group had the highest values of DC and VMH, followed by 0.50, 1.00, and 1.50 mm, respectively, while the 2.00 mm group showed the lowest values. The specimens irradiated for 40 s had greater DC and VMH than those irradiated for 20 s. RelyX U200 revealed higher values for both parameters compared to TheraCem cement. Conclusion: The polymerization of selfadhesive cement depends on the thickness of the monolithic zirconia, the light curing time, and the composition of the cement. The cement should be irradiated for a longer period than recommended to overcome the light attenuation of zirconia. TEGDMA-based self-adhesive cement showed a higher DC and VMH than BISGMA-based cement.
Multilateral Strategic Dialogue: Dilemmas and Obstacles
Authors: Arbatov A.
Published: July 2023

In the foreign policy section of the President V. Putin’s Address to the Federal Assembly on February 21, 2023, the most conspicuous was the new subject – the suspension of Russia’s participation in the New START Treaty. Among the reasons provided as justification of this decision was the absence of limitations on the nuclear forces of the two U.S. NATO allies – the Great Britain and France. Most probably, the main reason for the decision of the Russian leadership on the New START was political in nature – countering the policy of the U.S. and its allies, aimed at the defeat of Russia in the military conflict in Ukraine. At the same time, the suspension of the New START is prone with the break of the treaty-based strategic relationship of the two nuclear superpowers and the collapse of the whole regime of nuclear arms control. Still, provided improvement of the international politics: peaceful settlement of the military conflict in Ukraine, moving of the West and Russia away from the overwhelming confrontation – the resumption of the strategic limitation dialogue between the U.S. and Russia is possible. However, the subject of involving the Great Britain and France in arms control will stay on the agenda. Thirty years ago, the sum of their forces was about 4% of the strategic forces of each of the two superpowers, whereas now it is close to 35% due to the reductions of the U.S. and Russian strategic arms since 1991. Resolving this problem would require innovative application of legal norms and the use of the experience and precedents elaborated during half a century of strategic negotiations.
Structural Change in American Health Care
Authors: Guchanova A.
Published: July 2023

The article looks at the state of the U.S. healthcare at the end of the pandemic which brought to light a range of systemic problems of the industry: low efficiency at extremely high cost, inequities to health care access and a strong divide in the American society on healthcare issues. The author examines the key factors that will shape the future of the industry. Among them are an uncertain economic situation and high inflation rates, the rollback of the Medicaid continuous enrollment provisions, the end of the public health emergency and the population aging. The divided Congress also won’t allow the democratic administration to realize large-scaled reforms announced by the President during the race. At the same time some provisions of the Inflation Reduction Act of 2022 will bring some changes to the industry. The analysis allowed the author to come to the following conclusions. American healthcare is experiencing a structural change. On the one hand, the system has to adapt to an endemic future. On the other hand, the difficult economic situation resulting from the COVID‑19 pandemic will be another stress test for the industry: shortages of medical personnel, unprofitable medical facilities, rising prices for medical care, and a likely increase of the uninsured. Many traditional players will need to review their operations. Non-traditional retail giants could change game rules and offer more efficient models for managing and health care delivery. Addressing the issue of equitable access to health care will require further intervention by the federal government. Healthcare will be one of the key topics in the 2024 presidential election.
Construction of New Identities in Modern Kazakhstan: Trends and Reference Рoints
Authors: Romanova A. , Morozova E.
Published: July 2023

The authors consider identity as the most important source of legitimization of the Kazakhstani statehood. The repertoire of new identities, the construction process of which continues in the Republic of Kazakhstan, includes national identity (that balances between civil and ethno-cultural elements), Turkic pan-identity, Central Asian geopolitical identity, Eurasian civilizational identity and macro-regional Caspian identity. The authors attempt to substantiate the contradiction between the goals and reference points outlined in state documents on identity policy and real trends and landmarks in the continuing process of identity construction in the modern Kazakhstan. The multivector foreign policy of the Republic of Kazakhstan underpins the shaping of competing identities, with the Turkic identity developing most intensively. The growth of socio-political divisions (ethnic, confessional, settlement, etc.) produces a cumulative effect that makes Kazakhstan a “divided society”. The article examines the priorities of memory and language policies and reveals personalistic identifiers reflected in mass consciousness. The authors also focus on the contradictory nature of the ongoing identity policy as a challenge to societal security, considering that “split” social spaces may produce explosive conflict situations.

The COVID-19 pandemic has triggered an economic crisis with a global impact, affecting entities from many fields of activity, but particularly those from the production, transport, tourism, technological services sectors (Donthu & Gustafsson, 2020). Most countries have responded to this pandemic with travel bans, restrictions, and a series of health regulations aimed at managing the pandemic situation (Jones & Nguyen, 2021). The study aims to explore how and to what extent the capital structure and other financial characteristics of tourism organizations (one of the most affected sectors) influenced their financial performance during the 2007- 2008 global financial crisis and the COVID-19 pandemic. In this sense, a sample represented by 15 organizations in the field of tourism, listed on the Bucharest Stock Exchange (BSE), was subjected to analysis, the analysis period being 2007-2021. Ten independent variables were included in the study (cash ratio, current ratio, financial stability coefficient, debt-to-assets ratio, degree of coverage, total assets turnover, current assets turnover, accounts receivables turnover, cost to income ratio, and gross profit margin) from 2007-2021, for the evaluation of the capital structure and other financial characteristics of tourism organizations. After processing the data, it was found that the financial performance of organizations in the field of tourism is significantly influenced by the indicators of total asset turnover, debt-to-assets ratio, cash ratio, and financial stability coefficient.

Published: July 2023

This research investigates the potential application of generative language models, especially ChatGPT, in aviation safety analysis as a means to enhance the efficiency of safety analyses and accelerate the time it takes to process incident reports. In particular, ChatGPT was leveraged to generate incident synopses from narratives, which were subsequently compared with ground truth synopses from the Aviation Safety Reporting System (ASRS) dataset. The comparison was facilitated by using embeddings from Large Language Models (LLMs), with aeroBERT demonstrating the highest similarity due to its aerospace-specific fine-tuning. A positive correlation was observed between synopsis length and their cosine similarity. In a subsequent phase, human factor issues involved in incidents as identified by ChatGPT were compared to human factor issues identified by safety analysts. A concurrence rate of 61% was found, with ChatGPT demonstrating a cautious approach towards attributing human factor issues. Finally, the model was used to attribute incidents to relevant parties. As no dedicated ground truth column existed for this task, a manual evaluation was conducted. ChatGPT attributed the majority of incidents to the Flight Crew, ATC, Ground Personnel, and Maintenance. This study opens new avenues for leveraging AI in aviation safety analysis.
A Reduced Order Model for Monitoring Aeroengines Condition in Real-Time

Published: July 2023

A reduced order model is developed to monitor aeroengines condition (defining their degradation from a baseline state) in real-time, by using data collected in specific sensors. This reduced model is constructed by applying higher order singular value decomposition plus interpolation to appropriate data, organized in tensor form. Such data are obtained using a detailed engine model that takes the engine physics into account. Thus, the method synergically combines the advantages of data-driven (fast online operation) and model-based (the engine physics is accounted for) condition monitoring methods. Using this reduced order model as surrogate of the engine model, two gradient-like condition monitoring tools are constructed. The first tool is extremely fast and able to precisely compute `on the fly’ the turbine inlet temperature, which is a paramount parameter for the engine performance, operation, and maintenance, and can only be roughly estimated by the engine instrumentation in civil aviation. The second tool is not so fast (but still reasonably inexpensive) and precisely computes both, the engine degradation and the turbine inlet temperature at which sensors data have been acquired. These tools are robust in connection with random noise added to the sensors data and can be straight forwardly applied to other mechanical systems.
Earthquake Footprints for Predicting Events
Authors: Greer Kieran
Published: July 2023

This paper considers the problem of predicting earthquakes. It uses a small amount of information to create a descriptive key that can be used as a footprint to describe an event. A frequency grid clusters events that occurred at the same time and then the algorithm measures the history of these events over preceding days, in particular the gaps when the events did not occur. The clusters with the time gaps can be used to create the footprint description and results suggest that seismic events can in fact be traced using this, and subsequently recognised again, if the same conditions occur. Greek and USA datasets have been looked at and the prediction accuracy can be 70% or better. The author therefore suggests that this is an interesting method that deserves attention.

Oncological changes in the prostate are a common cause of death among elderly men. Malignant cells are difficult to identify at early stages, which are asymptomatic. The patient often seeks medical assistance when the disease has already progressed, and the treatment is less effective. Early diagnosis of prostate cancer (PC) is thus one of the priority tasks of modern urology and healthcare in general. The aim of this study is the detection of microRNAs (miRNAs), which are known to be associated with PC. The detection of the target miRNAs in human plasma samples has been performed with a nanoribbon biosensor system, which was based on "silicon-on-insulator" structures (SOI-NR biosensor). In order to provide biospecific detection of the target miRNAs, the surface of individual nanoribbons has been modified with DNA oligonucleotide probes (oDNA probes), whose nucleotide sequences were complementary to those of the target miRNAs. The high detection sensitivity has been demonstrated with the use of model oDNAs, which are complementary to nanoribbon-immobilized oDNA probes, in buffer solutions. The sensitivity threshold was 1.1 × 10-17 M. The successful detection of target miRNAs, isolated from real plasma samples of PC patients, has also been demonstrated. We believe that the development of highly sensitive nanotechnology-based biosensors for PC markers is a step towards personalized medicine.

The use of metal oxide nanoparticles as an alternative antimicrobial agent has gained attention due to the increasing problem of antibiotic resistance. Understanding its properties and potential benefits can contribute to the development of more effective and sustainable treatments in veterinary medicine. The aim of this study was to characterize TiO2-NP formulations and evaluate their antibacterial and wound healing abilities. The diameters and zeta potentials were determined using the Zetasizer in conjunction with dynamic light scattering. The agar-well diffusion method, time-kill kinetic assay and crystal violet assay were used to evaluate their antimicrobial activities. Wound healing assays were conducted both in-vitro and in-vivo. The study demonstrated that TiO2-NP formulations exhibit significant antimicrobial properties against various bacterial strains such as S. aureus and E. coli. No measurable E. coli growth was observed within a 15-mins period following exposure to TiO2-NP formulations. The TiO2-NP formation can improve wound healing by enhancing cell migration and collagen formation in both in-vitro and in-vivo conditions. In summary, our study suggests that TiO2-NP has the potential for use as an antimicrobial agent for animal wound treatment due to its ability to suppress bacterial growth and biofilm formation, as well as to enhance wound healing.

In order to explore the genetic diversity of the extremely small population wild plant Habenaria dentata and protect and optimize its wild resources. The genetic diversity of 133 samples from 6 wild populations of H.dentata was analyzed by ISSR molecular marker technique to provide a scientific basis for the screening of improved germplasm resources. The results show that the average number of alleles (Na) was 1.765, the average number of effective alleles (Ne) was 1.424, the average Nei 's gene diversity index (He) was 0.252, the average Shannon information diversity index (I) was 0.381, and the average percentage of polymorphic loci (PPL) was 76.499%. The variation within populations was 77.34%, and the variation between populations was 22.66%. Gene flow (Nm) was 1.705 8, greater than 1. The results of cluster analysis showed that the six populations were mainly divided into four branches and not classified according to geographical location. There was no significant correlation between geographical location and genetic distance between populations (r=0.557, P>0.05). The genetic diversity of H.dentata is high. Among the six wild populations, the genetic diversity of Mulun population is the highest and this population can be used as a key protection unit.
Nearshore Observations and Modeling: Synergy for Coastal Flooding Prediction
Authors: Postacchini Matteo , Melito Lorenzo , Ludeno Giovanni
Published: July 2023

Coastal inundation is recently requiring a significant attention worldwide. The increasing frequency and intensity of extreme events (sea storms, tsunami waves) are highly stressing the coastal envi-ronments, e.g. endangering a large number of residential areas, ecosystems, tourist facilities, and also leading to potential environmental risks. Predicting such events and the generated coastal flooding is thus of paramount importance and can be reached by exploiting the potential of different tools, like remote sensors and numerical modeling. To this aim, a combination is possible between marine radars and wave-resolving propagation models. While instruments like X-band radars are able at precisely reconstructing both wave field and bathymetry within a coastal area that is some kilometers offshore, wave-resolving Boussinesq-type models can reproduce the wave propagation in the nearshore and the consequent coastal flooding. The present work illustrates the reconstruc-tion of coastal data (wave field and seabed depth) conducted using radar signals and a specifically suited data processing, named “Local Method”, and the use of such coastal data to run numerical simulations of wave propagation (using the FUNWAVE-TVD solver) aimed at reproducing coastal inundation over different scenarios. Such scenarios are built using two different European beaches, i.e. Senigallia (Italy) and Oostende (Belgium), and three different directional spreading values, to evaluate the performances in case of either long- or short-crested waves. The overall validation of the methodology, in terms of maximum inundation, shows good performances, especially in case of short-crested wind waves. Furthermore, the application on the Oostende beach demonstrates that the present methodology might work only using open-access tools, i.e. an easy investigation of the coastal inundation and a potential low-cost integration into early warning systems.
