Challenges to the development of the welfare State in Portugal and Greece
Authors: Alexopoulou Kleoniki , Amaral Luciano
Published: October 2022

Portugal and Greece under crisis applied adjustment programs (2010-2018) as conditionalities for receiving loans by the Troika. Both count among the most poor and unequal countries in the EU and their welfare states have been built recently. Our main research objective is to conduct a comparative analysis of the impact of social policy reforms on public expenditures, development and welfare indicators such as poverty, inequality, unemployment, net earnings, and emigration. If results differed in the two cases, what are the reasons? Is it due to previous growth levels, exogenous factors (adjustment programs) or endogenous ones (welfare state models) or post-Troika governments? We retrieve evidence from secondary literature, state archival documents, IMF and EC evaluation reports. We elaborate on statistical datasets retrieved from Eurostat. We find that welfare state components, i.e. health and employment levels, were deeply affected in Greece and we explain processes of divergence towards a universalist model.

Vectors of the Youth Network Eco-Movement’s Evolution
Authors: Korotkova A.
Published: October 2022

The article analyzes the activities of the youth environmental movement “Fridays for Future” initiated in 2018 by the Swedish student Greta Thunberg. The features of its network structure, positive and negative factors for the development of the community that arise from this structure are emphasized. The novelty of the presented work consists in the analysis of the distinguishing factors of this initiative from the youth units of traditional public associations. Firstly, officially the “Fridays” were not created by any of the previously operating “adult” organizations. Secondly, this movement of teenagers has gained mass character in many countries of the world. Thirdly, it has become a symbol of a real, almost breakthrough and widespread promotion of the climate agenda. The purpose of the article is, on the one hand, to show which features of the movement strengthen it and can sometimes serve as an example for “adult” organizations. On the other hand, it is to outline the circle of threats to its participants and to the agenda for which they are fighting with all the force of youthful maximalism. The network structure, the availability of the necessary technologies, the absence of formalism and hierarchy creates all the prerequisites for the rapid numerical growth and popularity of the “Fridays”. However, the same traits form a breeding ground for various kinds of manipulations and provocations. In order to successfully promote teenage protests, it is necessary to maintain a strict balance, which can be disrupted by manifestations of radicalism. The author emphasizes the fact that the “baggage” of social activity accumulated at such a young age will be taken by the participants of the “Fridays” into the future. Currently, they are building connections and gaining experience unthinkable for previous generations, which will affect not only the political situation down the road. The type of society formed of such elements in the future may differ significantly from the usual, traditional one.
New Vectors of German Energy Policy
Authors: Khorolskaya M.
Published: October 2022

The article is devoted to energy policy of Germany. In the coalition treaty, the new German “red-green-yellow” coalition confirmed the commitment to achieve climate neutrality by 2045. In line with this goal Germany has developed a strategy to move away from coal as a primary source of energy. And, in the meantime, Berlin will close the last three Nuclear Power Plants by the end of the year 2022. The Russian special military operation in Ukraine has influenced the German energy policy significantly. Since February 2022, the German government has put a premium on substitution of Russian energy. The aim of this article is to analyze the coherence of the two policies: energy transition and rejection of Russian energy resources. The author explores phasing out nuclear power and coal, import of oil and gas, development of hydrogen production and renewables in Germany. The analysis revealed that two tracks do not complement each other. Both tracks should trace to the same goal – carbon-free energy, – but they have different temporal frameworks. While political elites claim to phase out Russian fuels within two years, the energy transition should take around 30 years. The natural gas was supposed to be the transitional energy, but more than half of it comes from Russia. Substitution of Russian coal and Russian oil requires more investment, and it could reduce the ability to subsidize renewables. Potential cooperation between Germany and Russia in hydrogen production was frozen. Only the policy aimed at improving energy efficiency and developing new building standards is likely to fit both tracks.

An Exact Solution to the Free Vibration Analysis of a Uniform Timoshenko Beam Using a Moment-Shear Force-Circular Frequency-Curvature Relationship
Authors: Fogang Valentin
Published: October 2022

This study presents an exact solution to the free vibration analysis of a uniform Timoshenko beam, with a harmonic vibration being assumed. The Timoshenko beam theory covers cases associated with small deflections based on shear deformation and rotary inertia considerations. In this paper, a moment-shear force-circular frequency-curvature relationship was presented. The complete study was based on this relationship and closed-form expressions of efforts and deformations were derived. The free vibration response of single-span systems and spring-mass systems was analyzed; closed-form formulations of matrices expressing the boundary conditions were presented and the natural frequencies were determined by solving the eigenvalue problem. Systems with intermediate mass, spring, or spring-mass system were also analyzed. Furthermore, first-order dynamic stiffness matrices in local coordinates were derived. Finally, a second-order analysis of beams resting on an elastic Winkler foundation was conducted. The results obtained in this paper were in good agreement with those of other studies.
A Study on the Acquisition Technology for Weak Seismic Signals From Deep Geothermal Reservoirs
Authors: Wang RuiZhen , Wang Jinkuan , Li Haidong , Cui Hongliang , Tang Meizhen
Published: October 2022

There are rich geothermal resources widely distributed in China. After years of continuous exploration and production, most of the shallow geothermal resources have been explored. At present, the exploration mainly focuses on deep geothermal resources. Among many geophysical exploration methods, seismic survey is the most effective means of geothermal resource exploration and production. The weak seismic reflection signal, low S/N ratio and poor imaging of thermal reservoirs due to their seismic geological conditions restrict the production and utilization of deep geothermal resources. In this paper, we considers based on the analysis of the geophysical characteristics of the thermal reservoir that the shielding effect of the strong wave impedance interface between the thermal reservoir and the caprock, the small reflection coefficient inside the thermal reservoir and the serious absorption and attenuation of seismic waves by high-temperature fluids such as hydrothermal fluids and steam in the thermal reservoirs are the main causes of the weak seismic waves in deep thermal reservoirs and proposes a series of seismic data acquisition technologies based on the high-precision vibroseis low-frequency shooting, high-sensitivity geophones long-spread receiving and small-bin size high-fold technologies. They are applied in the seismic acquisition of hot dry rocks (HDR) in Gonghe Basin, Qinghai and have a very good application effect.
Retweet Prediction based on Heterogeneous Data Sources: The Combination of Text and Multilayer Network Features
Authors: Meštrović Ana , Petrović Milan , Beliga Slobodan
Published: October 2022

Retweet prediction is an important task related to different problems such as information spreading analysis, the automatic detection of fake news, social media monitoring, etc. In this study we explore the possibilities of retweet prediction based on heterogeneous data sources. In order to classify the tweet according to the amount of retweets, we combine features extracted from the multilayer network and the text. More specifically, we introduce a multilayer framework that proposes the multilayer network representation of Twitter. This formalism captures different users' actions and complex relationships as well as other key properties of communication on Twitter. We select a set of local network measures from each layer and construct a set of multilayer network features. In addition, we adopt a BERT-based language model, namely Cro-CoV-cseBERT to capture high-level semantics and structure of tweets as a set of text features. Then, we train six machine learning (ML) algorithms: random forest, multilayer perceptron, light gradient boosting machine, category embedding model, neural oblivious decision ensembles and attentive interpretable tabular learning model in the task of retweet prediction. We compare the performance of all six algorithms in three different setups (i) using only text features, (ii) using only multilayer network features and (iii) using both sets of features. We evaluate all setups in terms of standard evaluation measures i.e. precision, recall, F1-score and accuracy. For this task, we first prepare and use an empirical dataset of 199,431 tweets in the Croatian language posted during the period between January 1, 2020 and May 31, 2021. Our results indicate that by integrating multilayer network features with text features the prediction model would perform better than using just one set of features.

Published: October 2022

Data on helminth parasites and epizoites is presented for the long-beaked and short-beaked common dolphins from the Southeast Pacific. Sampling in 1985-2000 was conducted mainly at six fishing ports in Peru and Ecuador where cetaceans were landed. From a total of 473 common dolphins sampled, we identified helminths including three species of Trematoda: Nasitrema globicephalae, Pholeter gastrophilus and Braunina cordiformis; three species of Nematoda, which includes Anisakis spp., Crassicauda sp. and Halocercus sp.; and two cestodes Tetrabothrius forsteri and Clistobothrium delphini (formerly Phyllobothrium delphini). No acanthocephalans were observed. No statistically significant sexual and ontogenetic variation in helminth prevalence was detected after which samples were pooled. The highest prevalence in the long-beaked common dolphin (n=440) was observed for N. globicephalae (96.3%) in cranial sinuses, Crassicauda sp. (83.3%) in mammary glands, Crassicauda sp. (78.8%) infesting the cranial sinuses, followed by Cl. delphini (28.6%) in the blubber and P. gastrophilus and B. cordiformis (20.4%) in the digestive tract. Although comparative testing was unfeasible due to minimal samples of short-beaked common dolphin (n=33), several of the same helminth species were found, but not N. globicephalae nor B. cordiformis. No cyamids were encountered while pseudo-stalked barnacles Xenobalanus globicipitis were common. No new (global) helminth host records are revealed for common dolphins, but this study presents a first checklist of parasites separately for the Southeast Pacific long-beaked and short-beaked common dolphins. Future work should include exhaustive laboratory-based necropsies, enhanced sampling of the short-beaked form, focus on intermediate hosts and parasitic pathology, including potential human health impact from consumption of small cetaceans.
Commercial Topical Probiotics for the Skin Microbiome: The Majority Do Not Contain Live Microbes and May Not Satisfy Criteria for Safe and Effective Use
Authors: Wallen-Russell Christopher , Wallen-Russell Samuel
Published: October 2022

In this paper we aim to help topical probiotics research and development achieve its potential as an incredible future solution for skin problems by investigating whether the current products on the market satisfy criteria for safe and effective use on the skin microbiome. As previously defined, this includes whether they use microbes known to be part of a healthy skin microbiome and in healthy amounts. In addition, we evaluate whether they contain live microbes, and therefore can be classified as probiotics according to the WHO’s definition. Using recent market analysis at least 84% of products do not contain live microbes. Of the products that appeared to use live microbes, they contained those used in research and development of probiotics for the gut. Due to the varying composition of each person’s microbiome, there is not a one size fits all probiotic solution. Personalisation of probiotics products is essential to satisfy the criteria for safe and effective use, but none of the products on the market, understandably, offer this. Upsetting the delicate ecosystem balance of the skin microbiome could have damaging effects and regulation could help to stop a loss of trust between consumers and cosmetics industry. Future work will perform an in-depth evaluation of the topical probiotics on the market in the EU, USA, and Canada. We will also investigate how to move the topic closer to achieving its potential by updating the criteria, including by discussing how to measure the success of a probiotic solution.
Consciousness: A Strategy for Behavioral Decisions
Authors: Grinde Bjørn
Published: October 2022

Definition: Most multicellular animals have a nervous system that is based on the following three components: 1) Sensory cells gather information and send it to processing units; 2) the processing units use the information to decide on what action to take; and 3) effector neurons activate the appropriate muscles. Due to the importance of making the right decisions, evolution made profound advances in the processing units. I shall review present knowledge regarding the evolution of neurological tools for making decisions, here referred to as strategies or algorithms. Consciousness can be understood as a particularly sophisticated strategy. It may have evolved to allow for the use of feelings as a ‘common currency’ to evaluate behavioral options. The advanced cognitive capacity of species such as humans further improved the usefulness of consciousness, yet in biological terms it does not seem to be an optimal, fitness-enhancing strategy. A model for the gradual evolution of consciousness is presented. There is a somewhat arbitrary cutoff as to which animals have consciousness but based on current information it seems reasonable to restrict the term to amniotes.

Este estudo teve como objetivo analisar as características das amostras questionadas de tecidos rígidos enviadas para análise de DNA forense, especificando o tipo e a região anatômica alvo de coleta, bem como a viabilidade da amostra após o processamento. Caracterizada por ser de corte transversal, com abordagem quantitativa e descritiva, utilizou dados secundários extraídos de planilhas do Instituto, com os quais construiu banco de dados, posteriormente analisado. Os resultados demonstraram que ossos e dentes são coletados como amostra para os testes de DNA, representando o percentual de 47,4% de todos os exames recebidos no ano de 2020, sendo 99,5% provenientes de crimes contra a vida. Das amostras obtidas de tecido rígido, 42% tiveram processamento concluído (39,1% para dentes e 42,6% para ossos), 10% não concluído (17,2% para dentes e 8,5% para ossos) e 48% constavam como não informado. Todas as amostras compostas por dente não especificaram a classificação dentária. Já as amostras compostas por ossos corresponderam a fragmento ósseo não especificado em 81% dos casos, 13,4% eram fragmento de fêmur e o percentual restante distribuído entre fragmentos de clavícula, crânio, escápula, fêmur, manúbrio, osso longo, tíbia, vértebra, osso esterno, mandíbula e ulna, variando entre 1-2% para cada. Pode-se concluir que o perfil dos exames de DNA extraído de amostras de tecidos duros do Instituto pesquisado é composto por ossos e dentes, sendo em sua maioria por fragmentos ósseos de vários tipos, principalmente fêmur, sendo necessária a melhor qualificação dos tipos de amostra utilizados para extração.

Dimorfismo sexual del agujero magno en tomografías de una población peruana
Authors: Victoria Parra Diana J , Súarez Ponce Daniel Guillermo , Velezmoro Montes Ymelda Wendy , Vigo Garcia Carlos
Published: October 2022

Introducción: La base del cráneo es una estructura compacta, muy resistente a los daños físicos, la robustez del hueso occipital y la posición anatómica protegida del agujero magno bajo una profundidad de tejido blando pueden hacerlo menos vulnerable a la fragmentación y a los efectos de los procesos tafonómicos en comparación con otras estructuras óseas, lo que permite utilizarlo para estimar el dimorfismo sexual. Objetivo: Establecer la relación entre el dimorfismo sexual y la morfometría del agujero magno en tomografías de pacientes mayores o iguales a los 18 años que asistieron a consultorios privados en Lima metropolitana, durante los años 2015 al 2020.

Objetivo: Evaluar la máxima tensión compresiva en incisivos centrales superiores restaurados con postes de fibra de vidrio y tres tipos de coronas por método de elementos finitos MEF. Materiales y métodos: El estudio fue un ensayo de laboratorio virtual y descriptivo. Se confeccionaron 3 modelos virtuales mediante el programa SolidWorks 2017, a partir de incisivos centrales superiores rehabilitados con postes de fibra de vidrio y corona metal-cerámica, corona de disilicato de litio monolítica y corona de zirconio-cerámica; luego, estos fueron sometidos a una carga oclusal oblicua de 150 N con una angulación de 45°, distribuida hacia la cara palatina. El análisis de las tensiones se realizó mediante la comparación de las tensiones máximas, mínimas y equivalentes de Von Mises. Resultados: La máxima tensión compresiva se encontró a nivel cervical en la zona vestibular de cada una de las coronas, siendo el diseño 3 (corona de zirconio-cerámica) el que presentó mayor tensión compresiva, con 73,89 MPa, seguido por el diseño 2 (corona de disilicato de litio), con 63,42 MPa, y el diseño 1 (corona metal-cerámica), con 48,4 MPa. Conclusión: La corona zirconio-cerámica distribuye mejor la tensión a lo largo del diente, ya que, por su rigidez, absorbe las tensiones que se concentran especialmente en cervical, lo que podría indicar que es la opción más apropiada para rehabilitar dientes tratados endodónticamente.

A Hybrid SEIHCRDV-UKF Model for COVID-19 Prediction. Application on real-time data
Authors: Papageorgiou Vasileios E. , Tsaklidis George
Published: October 2022

The prevalence of COVID-19 has been the most serious health challenge of the 21th century to date, concerning national health systems on a daily basis, since December 2019 when it appeared in Wuhan City. Prediction of pandemic spread plays an important role in effectively reducing this highly contagious disease. Nevertheless, most of the proposed mathematical methodologies, which aim to describe the dynamics of the pandemic, rely on deterministic models that are not able to reflect the true nature of the spread of COVID. In this paper, we propose a SEIHCRDV model – an extension of the classic SIR compartmental model – which also takes into consideration the populations of exposed, hospitalized, admitted in intensive care units (ICU), deceased and vaccinated cases, in combination with an unscented Kalman filter (UKF), providing a dynamic estimation of the time dependent parameters of the system. Apparently, this new consideration could be useful for examining also other pandemics. We examine the reliability of our model over a long period of 265 days, where we observe two major waves of infection, starting in January 2021 which signified the start of vaccinations in Europe, providing quite encouraging predictive performance. Finally, special emphasis is given to proving the non-negativity of SEIHCRDV model, to achieve a representative basic reproductive number R0 and to investigating the existence and stability of disease equilibriums in accordance with the formula produced to estimate R0.

Purpose: The aim of this study is to evaluate the clinical risk factors associated with maternal death in pregnant women infected by COVID-19. Material and methods: This is a multicenter prospective study in Indonesia, included all pregnant women with confirmed COVID-19. Participants was divided into two groups based on the final outcomes: maternal death group and survived group. The main outcomes evaluated were: maternal background, clinical risk factors, comorbidities, clinical characteristics, and laboratory results. Results: There were 89 participants in the maternal death group and 1673 in survived group. The maternal death group have an older maternal ages (32 vs 31 years old,p=0.03) and earlier gestational ages during admission (33 vs 37 weeks,p=0.000). The maternal death group have a significantly higher rate of cardiac disease (6.5% vs 1.2%, p=0.004), acute kidney injury (5.2% vs 0.3%, p=0.000), coinfections (29.9% vs 10.8%, p=0.000), and anemia (14.3% vs 6.7%,p=0.012). The maternal death group have a higher level of maternal blood leukocyte (13970 vs 10345), netrofil 75.7 vs 70), ALT (47 vs 23), AST (26 vs 19), CRP (37.4 vs 0.7), and procalcitonin (0.27 vs 0.06) (p<0.05). The risk factors that independently related to maternal death are fever (Exp(B): 12.847, 95% CI: 5.638-29.277;p=0.000), pneumonia from chest x-ray (Exp(B): 2.524, 95% CI: 1.163-5.479;p=0.019), and ICU admission (Exp(B): 49.430, 95% CI: 21.024-116.215;p=0.000).Conclussion: Our research indicates that the presence of fever, pneumonia, and ICU hospitalization are independently associated with maternal mortality in COVID-19-infected pregnant women.

Centrifugal compressors are widely used in ships, automobiles, aerospace and other fields. At present, the centrifugal compressor is usually designed with splitter blades to achieve a high pressure ratio and avoid airflow blockage at the leading edge throat of the main blade. This paper offers a multivariable optimization method for splitter blades design of centrifugal compressor. The length and circumferential position of the splitter blades are coupled to optimize the isentropic efficiency by using the Latin hypercube sampling, Regression Kriging algorithm and genetic algorithm. After optimization, the results show that the length of the splitter blades is shorter and its position is inclined to the pressure surface of the main blades. The maximum isentropic efficiency increased by 0.62%, the flow rate of the impeller surge point increased by 1.78%, and the flow rate of the plug point increased by 1.74%. After optimization, the low-speed zone of the flow field in the impeller decreases and the internal passages become more smooth. Besides, the degree of airflow obstruction is reduced, and the overall efficiency of the impeller is improved. The multivariable optimization method which is based on the Regression Kriging algorithm has certain universality and can provide important reference for the splitter blades design of centrifugal compressors and other turbomachinery.

Breast cancer is the most malignant malignancy in women on a global scale. It can generally be divided into four main categories, of which estrogen receptor ER-positive breast cancer accounts for most breast cancer cases. RBCK1 protein is an E3 ubiquitin ligase containing the UBL, NZF, and RBR domains. It is well known to exhibit abnormal expression in breast tumors, making it a valuable diagnostic marker and drug target. Additionally, studies have confirmed that in breast cancer, about 25 to 40% of tumors appear as visible hypoxic regions, while in hypoxia, tumor cells can activate the hypoxia-inducing factor HIF-1 pathway and widely activate the expression of downstream genes. Previous studies have confirmed that HIF-1α is highly important in tumor recurrence and metastasis. This research aims to identify RBCK1 as an important regulator of HIF1α signaling pathway. Targeted therapy with RBCK1 could be a promising treatment strategy for ER-positive breast cancer.
