Metal cutting operations involve intense heat generation owing to plastic deformation of the work piece and due to friction at the tool-work piece and tool-chip interface. The heat generated in metal cutting unfavourably affects the quality and thus the functional performance of the product. It is known that quality and functional performance is the function of roughness and dimensional accuracy. To maintain a longer component life, along with the robust material choice, a component should have good surface finish and dimensional accuracy. While, for the organization to monitor and control their environmental issues in a holistic manner, emphasis in adopting eco-friendly practices and protecting environment has been growing continuously across all the business sectors. In this study, an attempt is made to optimize the process parameter of stainless steel AISI-410 alloy, a nuclear graded material, for better surface finish. For this, Taguchi L9 orthogonal array was utilise to identify the process parameter and cutting environment. Analysis of variance (ANOVA) was also conducted to highlight the significant parameter that affects the surface finish most. A statistical model to forecast the surface roughness was also developed and was validated by an experiment with a maximum error of 12%. Results indicates that feed rate is the most critical factor that effects the surface roughness with the contribution of 91.5%, followed by environment with 5.22% contribution, cutting speed and depth of cut with 2.7 % and 0.4 % respectively. The correlation coefficient of 0.9213 and conformation tests reveals that developed statistical model predicts surface roughness with the statistical error limit.

Bone remodeling process has been widely investigated in literature from an experimental and theoretical viewpoint. Indeed, the biological process of bone remodeling allows a continuous renewal of the microstructure over time and thus, it contributes to decrease the bone damage by repairing it. This research work aims to study the biological function’s (fbio) effects on the bone remodeling process trough bone density evolution. Parameter fbio is one of the important parameters that controls bone volume variation. The biological bone remodeling process is modeled in terms of equations describing the activity of the Basic Multi-cellular Units (BMU). We use a mathematical model to simulate damage repair, based on Garcia Aznar’s model. The results of simulation show a good match with experimental and clinical data: bone porosity decreases over time and decreases also as the biological factors increase. In the same view, the apparent density (ρa) decreases with bone volume fraction increases. We note that the governance of the evolution of bone density leads to consider the evolution of bone volume during youthful and the maturation phase with their saturation zone for adult in terms of growth.
THE CONCEPT OF INTEGRATED CITY DEVELOPMENT: EUROPEAN EXPERIENCE AND POSSIBILITIES OF ITS IMPLEMENTATION IN UKRAINE
Authors: GOLOVNYA Olena , KONDRATOVA Maryna
Published: October 2021

The authors investigate that the leading form of territorial and socio-economic organization of modern society are cities. At the same time, cities act as drivers of socio-economic development, political prosperity and social progress and will undoubtedly be important for the formation of competitiveness in the world.

It is established that one of the documents, which was developed with the participation of representatives of common European interests and promotes to integrated urban development, is the Leipzig Charter «Cities of Europe on the path to sustainable development». The practice of participatory management helps integrated urban development. Participatory management becomes relevant in the context of decentralization and community development, in particular participatory budgeting, which is the opportunity for city residents to participate in decision-making on how to allocate a certain part of the budget.

It is analysed, that plenty of international indexes is for the quantitative and quality estimation of development of cities, that allow to explore tendencies and estimate influence of political decisions and steps that is accepted within the limits of cities for the improvement of welfare of habitants. A category ‒ «Smart City» is investigated. It is set that in rating of Smart Cities Index the first places occupy New York, London, Paris, Tokyo, Reykjavik.

Among the terms of development of the integrated cities on the basis of conception of «Smart City» the following is highlighted: introduction of networks of generation 5G, continuous coverage of territories and access to the internet in difficult of access places, trouble-free simultaneous work in the network of enormous number of devices.

A collaboration and partnership with European societies and organizations help the Ukrainian cities in their integrated development. The theoretical and methodological basis of the study has become the scientific works of Ukrainian and foreign authors on integrated urban development based on European experience and guidelines and provisions of the European Union.
A reproducible systematic map of research on the illusory truth effect
Authors: Henderson Emma L. , Westwood Samuel J. , Simons Daniel J.
Published: October 2021

People believe information more if they have encountered it before, a finding known as the illusory truth effect. But what is the evidence for the generality and pervasiveness of the illusory truth effect? Our preregistered systematic map describes the existing knowledge base and objectively assesses the quality, completeness and interpretability of the evidence provided by empirical studies in the literature. A systematic search of 16 bibliographic and grey literature databases identified 93 reports with a total of 181 eligible studies. All studies were conducted at Western universities, and most used convenience samples. Most studies used verbatim repetition of trivia statements in a single testing session with a minimal delay between exposure and test. The exposure tasks, filler tasks and truth measures varied substantially across studies, with no standardisation of materials or procedures. Many reports lacked transparency, both in terms of open science practices and reporting of descriptive statistics and exclusions. Systematic mapping resulted in a searchable database of illusory truth effect studies (https://osf.io/37xma/). Key limitations of the current literature include the need for greater diversity of materials as stimuli (e.g., political or health contents), more participants from non-Western countries, studies examining effects of multiple repetitions and longer intersession intervals, and closer examination of the dependency of effects on the choice of exposure task and truth measure. These gaps could be investigated using carefully designed multi-lab studies. With a lack of external replications, preregistrations, data and code, verifying replicability and robustness is only possible for a small number of studies.

Various combinatorially non-local field theories are known to be renormalizable. Still, explicit calculations of amplitudes are very rare and restricted to matrix field theory. In this contribution I want to demonstrate how the BPHZ momentum scheme in terms of the Connes-Kreimer Hopf algebra applies to any combinatorially non-local field theory which is renormalizable. This algebraic method improves the understanding of known results in noncommutative field theory in its matrix formulation. Furthermore, I use it to provide new explicit perturbative calculations of amplitudes in tensorial field theories of rank r>2.
Idunn Mons: Evidence for Ongoing Volcano-tectonic Activity and Atmospheric Implications on Venus
Authors: D’Incecco P. , Filiberto J. , López I. , Gorinov D. A. , Komatsu G.
Published: October 2021

In 2010 the ESA Venus Express Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) instrument first observed 1 μm emissivity anomalies over the top and eastern flank of Idunn Mons (46° S; 146° W), a 200 km wide volcano located in Imdr Regio, a volcano-dominated large volcanic rise of Venus. The anomalies suggest the presence of chemically unweathered and fresh volcanic deposits, which provided the first hint that volcanism in this area may have been active during the past few million years. Subsequent studies have investigated the geologic and atmospheric evolution at Idunn Mons, but no study has comprehensively investigated the evolution and the implication for recent activity in Idunn Mons. Previous work, using both VIRTIS data and Magellan radar emissivity data, confirmed the occurrence of unaltered basaltic lava flows at Idunn Mons. Building on that previous work, experimental laboratory studies have revealed that chemical weathering on Venus may act much faster than previously expected, which suggests very young ages for these flows. This inference has been supported by investigations of the tectonic fracturing surrounding Idunn Mons. Finally, atmospheric data from VIRTIS also show regional anomalies in the speed of the winds in the lower atmosphere over Imdr Regio, which may be related to very recent or ongoing volcanism. In this paper, we take a comprehensive approach, using atmospheric to surface measurements, including recent laboratory experiments, to constrain the evolution of Idunn Mons. Our work suggests that Idunn Mons may be geologically both volcanically and tectonically active today.
The Sexual Function of Primiparous Women after Normal Delivery and Cesarean Section According to the Female Sexual Function Index
Authors: Kurniawati Eighty Mardiyan , Irwanto Sandy , Muhdi Nalini
Published: October 2021

BACKGROUND: Various anatomical and physiological changes occur to provide a suitable environment for fetal development during pregnancy. Changes in body shape and other physical changes also undergo changes and are associated with postpartum sexual dysfunction.

AIM: This study aims to measure and determine the difference in female sexual function index scores for primiparous women post normal delivery and post-cesarean section.

METHODS: An observational analytic study with a cross-sectional study design conducted in a hospital. This study involved 60 women with inclusion criteria aged 20–35 years, primiparous women with post-term pregnancy, primiparous women after normal delivery and cesarean section at 3–4 months, women who were married and living with their husbands and were willing to participate in this study. Data were analyzed descriptively and statistically.

RESULTS: The results showed that the cause of perineal damage was mostly due to the mediolateral episiotomy, the degree of perineal damage with Grade II status, and there was variation in the indication of an elective cesarean section. The statistical test results show that there was no difference in the type of delivery, both normal delivery and cesarean delivery on desire, arousal, satisfaction, lubrication, orgasm, and dyspareunia and the total female sexual index in primiparous (P > 0.05).

CONCLUSION: This study recommends that in primiparous women care, it is not advisable to choose one type of delivery as a form of prevention of postpartum sexual dysfunction. In addition, in the management of complaints of sexual dysfunction in primiparous it is not required to consider the type of delivery as the main cause.

Random initial value problems to non-homogeneous first-order linear differential equations with complex coefficients are probabilistically solved by computing the first probability density of the solution. For the sake of generality, coefficients and initial condition are assumed to be absolutely continuous complex random variables with an arbitrary joint probability density function. The probability of stability, as well as the density of the equilibrium point, are explicitly determined. The Random Variable Transformation technique is extensively utilized to conduct the overall analysis. Several examples are included to illustrate all the theoretical findings.

Numerous limitations of Shot-based and Content-based key-frame extraction approaches have encouraged the development of Cluster-based algorithms. This paper proposes an Optimal Threshold and Maximum Weight (OTMW) clustering approach that allows accurate and automatic extraction of video summarization. Firstly, the video content is analyzed using the image color, texture and information complexity, and video feature dataset is constructed. Then a Golden Section method is proposed to determine the threshold function optimal solution. The initial cluster center and the cluster number k are automatically obtained by employing the improved clustering algorithm. k-clusters video frames are produced with the help of K-MEANS algorithm. The representative frame of each cluster is extracted using the Maximum Weight method and an accurate video summarization is obtained. The proposed approach is tested on 16 multi-type videos, and the obtained key-frame quality evaluation index, and the average of Fidelity and Ratio are 96.11925 and 97.128, respectively. Fortunately, the key-frames extracted by the proposed approach are consistent with artificial visual judgement. The performance of the proposed approach is compared with several state-of-the-art cluster-based algorithms, and the Fidelity are increased by 12.49721, 10.86455, 10.62984 and 10.4984375, respectively. In addition, the Ratio is increased by 1.958 on average with small fluctuations. The obtained experimental results demonstrate the advantage of the proposed solution over several related baselines on sixteen diverse datasets and validated that proposed approach can accurately extract video summarization from multi-type videos.
Croire à la lettre

Published: October 2021

Ce volume propose une réflexion sur les relations entre la religion et l’épistolarité en France et en Grande-Bretagne, aux xviie et xviiie siècles. Douze spécialistes de la période, en histoire, théologie et littérature, s’interrogent sur des correspon­dances officielles ou clandestines, spirituelles ou pastorales, pour présenter un panorama des rapports entre les correspondances manuscrites ou imprimées et l’orthodoxie ou les hétérodoxies. Outil de communication entre les croyants, les églises et les communautés, mais aussi entre les membres du clergé et les fidèles, la lettre, qu’elle soit ouverte ou secrète, qu’elle appelle une réponse ou le silence, qu’elle soit cachée, codée, interceptée, imprimée ou diffusée, qu’elle soit isolée ou fasse partie d’un corpus plus large, fut le principal moyen d’expression de la piété et du sentiment religieux dans des siècles marqués par de profonds bouleversements épistémologiques. Prises dans leur ensemble, ces contributions constituent la première tentative d’étude croisée du religieux et de l’épistolaire dans l’espace européen entre Réforme et Révolution.

The Cartesian evil demon and the impossibility of the monstrous lie
Authors: González Rodrigo Alfonso
Published: October 2021

In this paper, I address the issue of whether the evil demon could have caused the idea of God. In order to determine the capabilities of the evil demon, I perform a thought experiment in which I reaffirm the conclusion that an imperfect being could have never caused an idea of perfection and infinitude, i.e., the idea of God. The article is divided into five sections and a conclusion. While the first section is introductory, the second looks at the problem of God and knowledge certainty. Elucidating how reality is gradual according to Descartes, in the third section I address the distinction between objective, formal and eminent reality. In turn, in the fourth section, I argue that if the objective reality of God exists, that is, an idea of perfection, the imperfect evil demon could have never caused it. The last section examines the reverse argument of the fourth section, viz, whether God could have caused the existence of evil and imperfection.
Keywords: God, evil demon, imperfection.
Anomaly Detection Using System Logs
Authors: Sinha Rohit , Sur Rittika , Sharma Ruchi , Shrivastava Avinash K.
Published: October 2021

Anomaly detection is a very important step in building a secure and trustworthy system. Manually it is daunting to analyze and detect failures and anomalies. In this paper, we proposed an approach that leverages the pattern matching capabilities of Convolution Neural Network (CNN) for anomaly detection in system logs. Features from log files are extracted using a windowing technique. Based on this feature, a one-dimensional image (1×n dimension) is generated where the pixel values of an image correlate with the features of the logs. On these images, the 1D Convolution operation is applied followed by max pooling. Followed by Convolution layers, a multi-layer feed-forward neural network is used as a classifier that learns to classify the logs as normal or abnormal from the representation created by the convolution layers. The model learns the variation in log pattern for normal and abnormal behavior. The proposed approach achieved improved accuracy compared to existing approaches for anomaly detection in Hadoop Distributed File System (HDFS) logs.

Published: October 2021

The purpose of this study is to reveal the dark side the Internet and establish a hierarchical framework to provide its governance path based on users' negative psychology. However, this hierarchical framework must consider unnecessary attributes and the interrelationships between the aspects and the criteria. Hence, fuzzy set theory is used for screening out the unnecessary attributes, a decision-making and trial evaluation laboratory (DEMATEL) is proposed to manage the complex interrelationships among the aspects and attributes, and interpretive structural modeling (ISM) is used to divide the hierarchy and construct a hierarchical theoretical framework. The results show that: (1) the institutional system is the driver of Internet governance improvement (2) personal values are the last link in the governance process (3) the governance transition from institutional system to values must cross the barriers of ethics and technology. This paper proposes a more systematic and integrated hierarchical framework which provides theoretical guidance to govern the dark side of the Internet.

Authors: Le Thi Thuy Trang , Nguyen Tat Thang , Nguyen Chuyen Thi Hong , Nguyen Trong Hao , Van The Trung
Published: October 2021

Background: Alopecia areata (AA) is a tissue-specific autoimmune disease characterized by non-scarring and rapid onset of hair loss. Interleukin (IL)-17A is mainly produced by T helper 17 (Th17) cells and may play a crucial role in the pathogenesis of various autoimmune diseases including AA.Objectives: We conducted this research to measure serum level of IL-17A in patients with AA and investigated its relationship with the clinical manifestations in patients with AA.Methods: We assessed 36 patients with AA and 20 healthy control subjects. Demographic information and clinical characteristics were determined by physical examination and via the review of medical history. Serum IL-17A was measured by using enzyme-linked immunosorbent assay.Results: Serum IL-17A concentration was significantly higher in patients with AA than in the control group (P=0.004). The AA patients with severe presentation, personal atopy, nail abnormalities, or active phase had significantly higher serum IL-17A levels compared to others without these signs.Conclusion: Increased serum IL-17A levels in patients with AA correlate with severity and indicate an active disease state. These findings suggest that IL-17A may play an important role in determining the pathogenesis of AA and may serve as a valuable clinical biomarker of this disease.

Published: October 2021

We continue studying the connection between Jacobi matrices defined on a tree and multiple orthogonal polynomials (MOPs) that was recently discovered. In this paper, we consider Angelesco systems formed by two analytic weights and obtain asymptotics of the recurrence coefficients and strong asymptotics of MOPs along all directions (including the marginal ones). These results are then applied to show that the essential spectrum of the related Jacobi matrix is the union of intervals of orthogonality.

Authors: ALKAN Sevil , ŞENER Alper , GÜÇLÜ KAYTA Safiye Bilge , AKÇA Anıl
Published: October 2021

Coxiella burnetii is an intracellular, Gram-negative bacteria and is the causative agent of Q fever, a zoonosis first described in Australia in 1937. It can cause endemics around the world. People usually get the disease by inhaling the contaminated aerosol produced by infected livestock. Contaminated milk, intradermal inoculation, sexual contact, blood transfusion, and transplacental route may also occur. The infective dose for humans is 1-10 bacteria. It is resistant to environmental conditions and can remain alive in animal wastes such as dust and fertilizer. Acute infection is typically asymptomatic or may manifest as a febrile flu-like illness, pneumonia, hepatitis, and central nervous system (CNS) infection. Q fever outbreaks are often caused by occupational exposure that includes shepherds, animal keepers, veterinarians, slaughterhouses or dairy workers, and laboratory personnel working with C. burnetii. During the course of the disease that cannot be distinguished from other pneumonia clinically; 2-10 fold increase in liver function tests, leukocytosis and thrombocytopenia, erythrocyte sedimentation rate and creatine kinase increase may be observed or laboratory findings may be normal. An immunofluorescent antibody (IFA) test, which is a serological reference method, should be requested from patients suspected for the diagnosis of Q fever.

Fizioterapija ima svoje mjesto u gotovo svim granama medicine, pa i kao dio liječenja bolesnika s malignim bolestima. U ovome se radu razmatra uloga fizioterapije u bolesnika s hematološkim malignim bolestima liječenih transplantacijom krvotvornih matičnih stanica. Prikazan je tijek liječenja transplantacijom krvotvornih matičnih stanica od pripreme za transplantaciju do razdoblja nakon transplantacije te problemi i komplikacije koje se pritom javljaju. Liječenje transplantacijom praćeno je nizom komplikacija kao što su promjene na muskoloskeletnom sustavu te na kardiovaskularnom i respiratornom sustavu. Posebno je izražen problem akutne i kronične reakcije transplantata protiv primatelja (graft versus host disease, GvHD). Način
liječenja kojem je bolesnik podvrgnut i sve komplikacije rezultiraju raznolikim ozbiljnim tjelesnim promjenama koje utječu na fizičko stanje i
kvalitetu života bolesnika, pa i na krajnji ishod liječenja. Fizioterapija tih bolesnika iznimno je važna u svakom trenutku liječenja, a njezini učinci na kvalitetu života bolesnika, smanjenje komplikacija i konačni ishod liječenja relativno su slabo istraženi. Zbog specifičnoga stanja i komplikacija nakon transplantacije hematološkim je
bolesnicima potreban jedinstven i složen pristup u fizioterapijskim procedurama. Međutim, ne postoje jasna uputstva i protokoli koje bi fizioterapeuti nužno slijedili i provodili u bolesnika liječenih transplantacijom krvotvornih matičnih stanica. Opisana su dosadašnja iskustva i navedeni mogući pristupi fizioterapiji tih bolesnika.

Published: October 2021

The paper represents a prototype of service-oriented tools for developing digital twins. These tools automate most of the stages in preparing and carrying out a computational experiment reducing the possibility of human error. Computational experiments based on simulation modeling are performed using the proposed tools. As an example in applying the represented tools, a digital twin of a heat pump used as environmentally-friendly equipment of an infrastructure object on the Baikal natural territory is considered. Owing to the growing anthropogenic load, special attention is paid to the objects located at the coast of Lake Baikal. During the simulation modeling, both the heat pump performance characteristics and retrospective meteorological data are used to predict climatic conditions and select optimal control parameters. In addition, the computational experiment has obviously shown that heat pump use significantly reduces the harmful effect on the environment.
