An Appropriate Technology Approach for Utilizing Plastic Waste Derived Cooking Fuel to Reduce Indoor Air Pollution from Solid Fuel Cooking
Authors: Foong Yansi , Browning Shelby , Seay Jeffrey
Published: December 2022

Combating the environmental crisis caused by mismanaged plastic waste is a global challenge, especially in developing regions due to a lack of recycling availability and waste management infrastructure. One way communities can combat this challenge is by using the process of slow pyrolysis to convert plastic waste into liquid cooking fuel. Using this fuel in cookstoves can help combat the public health issue caused by breathing in smoke from a cooking fire. Open fire cooking remains a common means of cooking in the developing world, and long-term exposure to smoke can lead to chronic lung and eye health problems. The burden of these health problems falls disproportionately on women. Our hypothesis is that switching from wood fire cooking to using stoves fueled by liquid fuel produced from waste plastic will have a positive impact on indoor air pollution, including particulate matter, sulfur dioxide, and carbon monoxide. To test this hypothesis, a series of experiments to measure particulate emissions, sulfur dioxide, and carbon monoxide were conducted. Cookstoves similar to those used in households in developing countries were used when conducting experiments. The results of these experiments indicated that polyfuel produces less particulate than fire wood, with an average PM2.5 of 7.7 μg/m3 compared with fire wood which had a PM2.5 of 325.6 μg/m3. Polyfuel also produces no sulfur dioxide emissions. Kerosene, which is a traditional cooking fuel in much of the world, produced sulfur dioxide emissions of 5.2 ppm under the experimental conditions. If implemented globally, the results of this research suggest that converting plastic waste into cooking fuel can not only reduce the amount of plastic waste entering the ecosystem but can also combat the global public health problems caused by open fire cooking.
A Scalable Smart Greenhouse Design For Mongolian Families
Authors: Kim Donald D. , Suh Doug Young
Published: December 2022

Life expectancy in Mongolia is male 63.8 and female 72.8. Total life expectancy is 68.1, which gives Mongolia a World Life Expectancy ranking of 132 in the WHO 2022 report. The number one reason for the mission of Mongolians is cardiovascular disease, which is closely related to their diet. The staple food of Mongolians is meat. The annual vegetable consumption of Mongolians announced by the UN in 2017 was 47.31 kg, far below the average value of 250 kg in developed countries. This paper proposes a smart greenhouse for families where Mongolian families can grow vegetables at home. This paper presents a smart home greenhouse that meets the environmental characteristics and requirements of the Mongolian region. We manage sensors and actuators through the Raspberry Pi platform to provide an environment necessary for cultivation. It describes the architecture of an integrated management system that stores sensor data in the cloud system's storage, apply reinforcement learning, and controls the operating point of the smart greenhouse. It describes how to manage the system internally using three layers, the physical layer, the embedded OS layer, and the application layer, and to communicate with the cloud through the IoT edge manager.

Influence of the moscow patriarchate on the National Identity in the Context of the russian War against Ukraine
Authors: Zdioruk Serhii , Palinchak Mykola
Published: December 2022

The factors of ethnicity and religion are the foundation of the national identity as seen across the peoples of our planet. Amid the russian war against Ukraine, the factors behind the formation and reinforcement of national identity have gained particular importance. Among those, religion occupies a distinct role; hence, in the modern age of cutting-edge scientific and technological advances of humanity, religion continues to have a colossal impact on virtually every facet of the functioning of society.
Therefore, national identity also constitutes a potent driving force behind all social processes: politics, economy, culture, and, ultimately, warfare. That is why the national identity of the Ukrainian people as a whole and every individual Ukrainian is so vital and valuable. Ukraine faces an extraordinary threat emanating from religious organisations with headquarters in the territory of the aggressor state, russia. It is especially true in the case of the moscow patriarchate (MP), functioning in Ukraine under the designation of the Ukrainian Orthodox Church (UOC).
Meanwhile, the Orthodox Church of Ukraine (OCU) was one of the first to appeal to the international community and world religious leaders to help stop russian armed aggression. The OCU also disseminates truthful information about Ukraine, primarily abroad, through the channels of church diplomacy.
Strengthening the identity of the Ukrainian nation and elimination of the imperial religious and ideological influence of the MP and russian eurasianism should be one of the priorities of the state security policy of Ukraine.
Keywords: Ukraine, russian aggression, OCU, tomos, UOC.
Stance of European Intellectuals on russia’s Aggression against Ukraine
Authors: Vidnianskyi Stepan
Published: December 2022

The article analyses the stance of prominent European intellectuals on the brutal military aggression against Ukraine, a sovereign European country, unleashed by russia, a terrorist-state, which challenged all the democratic values of the Western civilisation and brought humanity to the brink of World War III. In their public appearances, publications and civil engagement, the most prominent representatives of European elites have influenced considerably the European public perception of putin’s war against Ukraine. To wit, Germans Jürgen Habermas and Martin Schulze Wessel, French Françoise Thom and Jonathan Littell, Belgian Bart De Baere, Czech Jan Rychlík, the world-renowned American historian Timothy Snider, and other intellectuals firmly believe that not just putin, but also all russians are responsible for the war, having supported his criminal aggression. Moreover, they believe that Europeans should show utmost support to Ukraine, which is not just fighting against the aggressor for the sake of its existence, freedom, democracy, and pro-European choice, but also against totalitarianism for the sake of the future of Europe.
The author stresses that the Euro-Atlantic civilisation needs to unite in combating russia’s aggressive and insidious attempts at imposing on Europe, through its loyal foreign politicians, experts, and institutions, its desired perspective on the russian-Ukrainian war and, in general, Ukrainian history and culture. The author outlines three primary objectives of European intellectuals. The first lies in conveying the truth about the russian-Ukrainian war of 2014–22, its causes, and geopolitical implications, real and potential, to society. The second focuses on refuting russian deceitful propaganda. The third involves shedding light on the essence, components, and historical roots of ‘ruscism’, the dominant totalitarian ideology of contemporary russia, which poses a threat to the existence of the human civilisation and demands urgent attention and elimination.
Keywords: russia, Ukraine, aggression, Europe, intellectuals, public opinion.

Gaussian noise related to generalised Ehrenfest model
Authors: Miniailyk Y.
Published: December 2022

In this article we consider the generalization of Ehrenfest model, where at each moment of time not 1 but some k of n particles go from one box to another. We describe this process by a sequence of Bernoulli random vectors. We define related Bernoulli noise on a set of continuous functions for different times, and prove that it converges to Ornstein-Uhlenbeck sequence of Gaussian white noises when number of particles tends to infinity.
Recursive and non-recursive regression estimators using Bernstein polynomials
Authors: Slaoui Y. , Jmaei A.
Published: December 2022

If a regression function has a bounded support, the kernel estimates often exceed the boundaries and are therefore biased on and near these limits. In this paper, we focus on mitigating this boundary problem. We apply Bernstein polynomials and the Robbins-Monro algorithm to construct a non-recursive and recursive regression estimator. We study the asymptotic properties of these estimators, and we compare them with those of the Nadaraya-Watson estimator and the generalized Révész estimator introduced by [21]. In addition, through some simulation studies, we show that our non-recursive estimator has the lowest integrated root mean square error (ISE) in most of the considered cases. Finally, using a set of real data, we demonstrate how our non-recursive and recursive regression estimators can lead to very satisfactory estimates, especially near the boundaries.

Chinese Intellectuals’ Perspectives on Russia's Invasion of Ukraine
Authors: DEMİR Emre
Published: December 2022

The Russia-Ukraine war, its reasons and impact have been discussed by diplomats, politicians and intellectuals worldwide. While many accuse the Russian leadership and in particular Russian President Vladimir Putin for the war, some others criticize Western countries and principally the US for NATO’s eastward expansion and for disregarding Russia’s security concerns. Chinese intellectuals with diverse academic and political backgrounds have also contributed to these discussions and offered their assessments about the war in Ukraine as well as what kind of a policy China should follow. However, because of the sensitive relationship between the authoritarian party-state and Chinese intellectuals, Chinese intellectuals are in a delicate situation compared to intellectuals in the West. Despite this, the Chinese state’s relatively balanced and neutral stance and decision of not openly taking sides in the war provided a ground for Chinese intellectuals to publicly share their thoughts about both the war itself and China’s position towards Russia’s aggression. Nevertheless, due to its close relationship with Moscow, the Chinese state allows only a restricted space for intellectuals to share their views about the war, especially to anti-Russia voices. This study surveys these debates among Chinese intellectuals about the war in Ukraine as well as the policies that the Chinese leadership should follow.

Published: December 2022

Background: An excess of thyroid hormones in Graves’ disease (GD) has profound effects on systemic energy metabolism that are currently partially understood. In this study, we aimed to provide a comprehensive understanding of the metabolite changes that occur when patients with GD transition from hyperthyroidism to euthyroidism with methimazole treatment.Methods: Eighteen patients (mean age, 38.6±14.7 years; 66.7% female) with newly diagnosed or relapsed GD attending the endocrinology outpatient clinics in a single institution were recruited between January 2019 and July 2020. All subjects were treated with methimazole to achieve euthyroidism. We explored metabolomics by performing liquid chromatography-mass spectrometry analysis of plasma samples of these patients and then performed multivariate statistical analysis of the metabolomics data.Results: Two hundred metabolites were measured before and after 12 weeks of methimazole treatment in patients with GD. The levels of 61 metabolites, including palmitic acid (C16:0) and oleic acid (C18:1), were elevated in methimazole-naïve patients with GD, and these levels were decreased by methimazole treatment. The levels of another 15 metabolites, including glycine and creatinine, were increased after recovery of euthyroidism upon methimazole treatment in patients with GD. Pathway analysis of metabolomics data showed that hyperthyroidism was closely related to aminoacyl-transfer ribonucleic acid biosynthesis and branched-chain amino acid biosynthesis pathways.Conclusion: In this study, significant variations of plasma metabolomic patterns that occur during the transition from hyperthyroidism to euthyroidism were detected in patients with GD via untargeted metabolomics analysis.
Metformin and Cervical Cancer Risk in Patients with Newly Diagnosed Type 2 Diabetes: A Population-Based Study in Korea
Authors: Kim Hyun Min , Kang Min Jin , Song Sun Ok
Published: December 2022

Background: Cervical cancer is a prevalent malignancy that is a major health problem for women worldwide. The cancer-preventive properties of metformin are well-known, but insufficient data have been reported regarding its relationship to cervical cancer. Therefore, in a nationwide population-based study, we investigated the association between metformin use and cervical cancer incidence in patients with newly diagnosed type 2 diabetes.Methods: This retrospective cohort study used the Korean National Health Insurance claims database. Individuals newly diagnosed with type 2 diabetes between January 2005 and December 2009 were included. The occurrence of cervical cancer was explored by matching for age, economic status, region of residence, and use of anti-diabetic medication.Results: In total, 66,013 metformin users and 64,756 non-users were analyzed. Cervical cancer occurred in 219 metformin users (0.33%) and 274 metformin non-users (0.42%) (hazard ratio [HR], 0.783; 95% confidence interval [CI], 0.655 to 0.036; P=0.007). Moreover, cervical cancer risk was considerably reduced in those treated with a high dose (>1,200,000 mg) or for an extended period (≥2,000 days) compared to non-users (HR, 0.151; 95% CI, 0.093 to 0.243; P<0.001; and HR, 0.141; 95% CI, 0.077 to 0.258; P<0.001). The incidence was also significantly lower in metformin users among those over 50 years old (HR, 0.791; 95% CI, 0.650 to 0.961; P<0.001).Conclusion: Metformin use in patients with newly diagnosed diabetes was associated with a lower risk of cervical cancer in Korea. Furthermore, a significant association was found between the use of metformin and cervical cancer in a dose- and duration-dependent manner and among those over 50 years old.
Immune Checkpoint Inhibitors and Endocrine Disorders: A Position Statement from the Korean Endocrine Society

Published: December 2022

Immune checkpoint inhibitors (ICIs) including an anti-cytotoxic T-lymphocyte-associated antigen 4 inhibitor, anti-programmed cell death protein 1 (PD-1) inhibitors, and anti-PD-ligand 1 inhibitors are representative therapeutics for various malignancies. In oncology, the application of ICIs is currently expanding to a wider range of malignancies due to their remarkable clinical outcomes. ICIs target immune checkpoints which suppress the activity of T-cells that are specific for tumor antigens, thereby allowing tumor cells to escape the immune response. However, immune checkpoints also play a crucial role in preventing autoimmune reactions. Therefore, ICIs targeting immune checkpoints can trigger various immune-related adverse events (irAEs), especially in endocrine organs. Considering the endocrine organs that are frequently involved, irAEs associated endocrinopathies are frequently life-threatening and have unfavorable clinical implications for patients. However, there are very limited data from large clinical trials that would inform the development of clinical guidelines for patients with irAEs associated endocrinopathies. Considering the current clinical situation, in which the scope and scale of the application of ICIs are increasing, position statements from clinical specialists play an essential role in providing the appropriate recommendations based on both medical evidence and clinical experience. As endocrinologists, we would like to present precautions and recommendations for the management of immune-related endocrine disorders, especially those involving the adrenal, thyroid, and pituitary glands caused by ICIs.
Forecasting the Detection Capabilities of Third-generation Gravitational-wave Detectors Using GWFAST
Authors: Iacovelli Francesco , Mancarella Michele , Foffa Stefano , Maggiore Michele
Published: December 2022

We introduce GWFAST, a novel Fisher-matrix code for gravitational-wave studies, tuned toward third-generation gravitational-wave detectors such as Einstein Telescope (ET) and Cosmic Explorer (CE). We use it to perform a comprehensive study of the capabilities of ET alone, and of a network made by ET and two CE detectors, as well as to provide forecasts for the forthcoming O4 run of the LIGO-Virgo-KAGRA (LVK) collaboration. We consider binary neutron stars, binary black holes, and neutron star–black hole binaries, and compute basic metrics such as the distribution of signal-to-noise ratio (S/N), the accuracy in the reconstruction of various parameters (including distance, sky localization, masses, spins, and, for neutron stars, tidal deformabilities), and the redshift distribution of the detections for different thresholds in S/N and different levels of accuracy in localization and distance measurement. We examine the expected distribution and properties of golden events, with especially large values of the S/N. We also pay special attention to the dependence of the results on astrophysical uncertainties and on various technical details (such as choice of waveforms, or the threshold in S/N), and we compare with other Fisher codes in the literature. In the companion paper Iacovelli et al., we discuss the technical aspects of the code. Together with this paper, we publicly release the code GWFAST,

Published: December 2022

Hot spots observed at the edges of extended radio lobes in high-power radio galaxies and quasars mark the position of mildly relativistic termination shock, where the jet bulk kinetic energy is converted to the internal energy of the jet particles. These are the only astrophysical systems where mildly relativistic shocks can be directly resolved at various wavelengths of the electromagnetic spectrum. The western hot spot in the radio galaxy Pictor A is an exceptionally good target in this respect, due to the combination of its angular size and high surface brightness. In our previous work, after a careful Chandra image deconvolution, we resolved this hot spot into a disk-like feature perpendicular to the jet axis, and identified it as the front of the jet termination shock. We argued for a synchrotron origin of the observed X-ray photons, which implied electron energies reaching at least 10–100 TeV at the shock front. Here, we present a follow-up on that analysis, proposing, in particular, a novel method for constraining the shape of the X-ray continuum emission with subarcsecond resolution. The method is based on a Chandra hardness map analysis, using separately deconvolved maps in the soft and hard X-ray bands. In this way, we have found there is a systematic, yet statistically significant gradient in the hardness ratio across the shock, such that the implied electron energy index ranges from s ≤ 2.2 at the shock front to s > 2.7 in the near downstream. We discuss the implications of the obtained results for a general understanding of particle acceleration at mildly relativistic shocks.
Le modèle économique chinois
Authors: Chimits François
Published: December 2022

Fin octobre 2022, le 20 e Congrès du parti communiste chinois a reconduit pour cinq ans le président (omnipotent) Xi Jinping à la tête de son pays. Dans le même temps, le conflit russo-ukrainien s’est installé dans la durée, avec des conséquences majeures à l’échelle mondiale, plaçant de nombreux pays dans une situation économique très incertaine. Dans ce contexte, il nous semble bienvenu de reprendre, dans ces colonnes, l’analyse de François Chimits publiée cet automne par Futuribles International, qui propose de faire le point sur l’économie chinoise et ses perspectives à l’horizon d’une dizaine d’années. Comment s’est installé et fonctionne ce modèle de développement atypique, alliant ouverture économique et autoritarisme politique ? Peut-il se maintenir durablement ? Quelles conditions économiques a-t-il instaurées pour les entreprises à la fois intérieures et étrangères, et quels scénarios peut-on envisager pour le modèle économique chinois dans l’économie internationale ? Telles sont certaines des questions abordées par l’auteur dans cet article.  S.D.

Gestion publique de Santé : Perception de la Cabine de télémédecine
Authors: Kondrateva Galina , Baudier Patricia , Ammi Chantal , Hikkerova Lubica
Published: December 2022

Les équipes de gestion de santé publique dans certains pays sont confrontées à des problèmes majeurs, tels que le manque de médecins ou d’infrastructures et de matériel de santé, des services d’urgence hospitaliers surchargés, des zones mal desservies par les services de santé ou, plus récemment, la mise en œuvre d’une gestion de crise pour faire face à la pandémie du Covid-19. Les solutions d’e santé pourraient aider à résoudre certaines de ces situations. Les jeunes générations en particulier auraient tendance à négliger leur santé, ce qui peut entraîner de futurs et graves problèmes de santé. Cet article vise à analyser la perception par les jeunes adultes d’un dispositif de téléconsultation, la cabine de télémédecine (CT). Il s’appuie notamment sur la Théorie du Comportement Planifié (Ajzen, 1991) et ses prolongements, pour mesurer l’influence des croyances comportementales et du contrôle perçu sur l’intention d’utiliser la CT. Cette étude applique une méthodologie quantitative. Les réponses de 150 étudiants inscrits en master dans des écoles de commerce françaises étaient prises en compte pour l’analyse. Les résultats, en utilisant une approche Partial Least Squares (moindres carrés partiels) précisément le Modèle d’équations structurelles (SEM), ont confirmé l’impact fort de variables du modèle : compatibilité et auto-efficacité pour l’adoption de la cabine de télémédecine. Cette recherche contredit par ailleurs le paradoxe de la personnalisation et de la vie privée, avec un accent particulier sur les soins de santé. Elle permet également d’identifier le paradoxe technologique de la population étudiée qui est généralement ouverte au partage de ses informations privées, mais qui est réticente à partager ses données de santé. Nos résultats pourraient être utilisés par les professionnels de santé et les pouvoirs publics pour répondre à l’incertitude concernant la qualité des services fournis par les solutions de e-santé, afin de mieux gérer l’allocation des ressources dans le système de santé publique ainsi que répondre aux problèmes actuels et cruciaux des services de santé.
Le sourire de Gratien : quelle figure pour le droit canonique au lendemain du centenaire de Dante ?
Authors: Minelli Chiara
Published: December 2022

L’article vise à vérifier la valeur de la littérature comme ressource pour le droit canonique contemporain. En effet, le jeu de miroirs entre la Divine Comédie et le droit canonique est particulièrement vivant et prometteur. L’essai se concentre sur le personnage de Gratien dans le Paradis de Dante. À la lumière d’un important débat entre la critique littéraire traditionnelle et la doctrine canonique italienne sur le sens de la référence du Grand Poète à l’œuvre d’harmonisation entre les deux fors attribuée au père de la science canonique, c’est-à-dire à la distinction entre for civil et for ecclésiastique ou bien entre for externe et for interne, on va redécouvrir la structure complexe du droit canonique. Une structure qui mérite une attention particulière dans l’élan réformateur de la législation canonique la plus récente et en même temps qui présente déjà en son sein une dimension dialogique intrinsèque, capable de se projeter vers l’extérieur sous la forme d’une comparaison toujours possible et peut être utile avec d’autres droits.
A posteriori grid method for a time-fractional Black-Scholes equation
Authors: Cen Zhongdi , Huang Jian , Xu Aimin
Published: December 2022

In this paper, a posteriori grid method for solving a time-fractional Black-Scholes equation governing European options is studied. The possible singularity of the exact solution complicates the construction of the discretization scheme for the time-fractional Black-Scholes equation. The $ L1 $ method on an arbitrary grid is used to discretize the time-fractional derivative and the central difference method on a piecewise uniform grid is used to discretize the spatial derivatives. Stability properties and a posteriori error analysis for the discrete scheme are studied. Then, an adapted a posteriori grid is constructed by using a grid generation algorithm based on a posteriori error analysis. Numerical experiments show that the $ L1 $ method on an adapted a posteriori grid is more accurate than the method on the uniform grid.
A pseudospectral method for investigating the stability of linear population models with two physiological structures
Authors: Andò Alessia , De Reggi Simone , Liessi Davide , Scarabel Francesca
Published: December 2022

The asymptotic stability of the null equilibrium of a linear population model with two physiological structures formulated as a first-order hyperbolic PDE is determined by the spectrum of its infinitesimal generator. In this paper, we propose a general numerical method to approximate this spectrum. In particular, we first reformulate the problem in the space of absolutely continuous functions in the sense of Carathéodory, so that the domain of the corresponding infinitesimal generator is defined by trivial boundary conditions. Via bivariate collocation, we discretize the reformulated operator as a finite-dimensional matrix, which can be used to approximate the spectrum of the original infinitesimal generator. Finally, we provide test examples illustrating the converging behavior of the approximated eigenvalues and eigenfunctions, and its dependence on the regularity of the model coefficients.
Effect of decay behavior of information on disease dissemination in multiplex network
Authors: Huo Liang'an , Meng Shiguang
Published: December 2022

The diseases dissemination always brings serious problems in the economy and livelihood issues. It is necessary to study the law of disease dissemination from multiple dimensions. Information quality about disease prevention has a great impact on the dissemination of disease, that is because only the real information can inhibit the dissemination of disease. In fact, the dissemination of information involves the decay of the amount of real information and the information quality becomes poor gradually, which will affect the individual's attitude and behavior towards disease. In order to study the influence of the decay behavior of information on disease dissemination, in the paper, an interaction model between information and disease dissemination is established to describe the effect of the decay behavior of information on the coupled dynamics of process in multiplex network. According to the mean-field theory, the threshold condition of disease dissemination is derived. Finally, through theoretical analysis and numerical simulation, some results can be obtained. The results show that decay behavior is a factor that greatly affects the disease dissemination and can change the final size of disease dissemination. The larger the decay constant, the smaller final size of disease dissemination. In the process of information dissemination, emphasizing key information can reduce the impact of decay behavior.
Prediction of coronary heart disease in gout patients using machine learning models

Published: December 2022

Growing evidence shows that there is an increased risk of cardiovascular diseases among gout patients, especially coronary heart disease (CHD). Screening for CHD in gout patients based on simple clinical factors is still challenging. Here we aim to build a diagnostic model based on machine learning so as to avoid missed diagnoses or over exaggerated examinations as much as possible. Over 300 patient samples collected from Jiangxi Provincial People's Hospital were divided into two groups (gout and gout+CHD). The prediction of CHD in gout patients has thus been modeled as a binary classification problem. A total of eight clinical indicators were selected as features for machine learning classifiers. A combined sampling technique was used to overcome the imbalanced problem in the training dataset. Eight machine learning models were used including logistic regression, decision tree, ensemble learning models (random forest, XGBoost, LightGBM, GBDT), support vector machine (SVM) and neural networks. Our results showed that stepwise logistic regression and SVM achieved more excellent AUC values, while the random forest and XGBoost models achieved more excellent performances in terms of recall and accuracy. Furthermore, several high-risk factors were found to be effective indices in predicting CHD in gout patients, which provide insights into the clinical diagnosis.
The numerical solutions for the nonhomogeneous Burgers' equation with the generalized Hopf-Cole transformation
Authors: Yan Tong
Published: December 2022

In this paper, with the help of the generalized Hopf-Cole transformation, we first convert the nonhomogeneous Burgers' equation into an equivalent heat equation with the derivative boundary conditions, in which Neumann boundary conditions and Robin boundary conditions can be viewed as its special cases. For easy derivation and numerical analysis, the reduction order method is used to convert the problem into an equivalent first-order coupled system. Next, we establish a box scheme for this first-order system. By the technical energy analysis method, we obtain the prior estimate of the numerical solution for the box scheme. Furthermore, the solvability and convergence are obtained directly from the prior estimate. The extensive numerical examples are carried out, which verify the developed box scheme can achieve global second-order accuracy for both homogeneous and nonhomogeneous Burgers' equations.
