Authors: Guerrero-Forero Alvaro Santiago , De la Torre Otilia Gallegos , Gómez-Carlín Luis A.
Published: May 2020

Patients who have undergone ankle arthrodesis frequently suffer from alterations in the adjacent joints and functional limitations. A 56-year-old female with a 22-year history of ankle arthrodesis underwent a conversion of ankle arthrodesis to total ankle replacement, followed by stabilization of the subtalar joint with a flexible system. The FAAM scale preoperative and eight-week postoperative scores were 39/100 and 88/100, respectively, and the SF-36 scale preoperative and eight-week postoperative scores were 37.52 and 73.61, respectively. In this case, ankle function was recovered after the conversion of ankle arthrodesis to total ankle replacement. With this technique, we obtained satisfactory functional results.

O objetivo deste estudo foi descrever o acesso ao tratamento e as necessidades terapêuticas dos pacientes que buscam atendimento nas clínicas do Curso de Odontologia da Universidade Federal de Santa Maria (Brasil) por meio dos encaminhamentos realizados pelo Serviço de Triagem do curso, bem como verificar quantos desses pacientes efetivamente receberam atendimento. Trata-se de um estudo observacional descritivo de caráter quantitativo, baseado em dados secundários existentes nos registros das listas de espera do Serviço de Triagem do curso e nos dados do software Gerenciador Odontológico usado para registro de procedimentos. Foram incluídos no estudo os dados dos pacientes que buscaram o serviço entre 2015 e 2017. Os dados foram analisados utilizando o programa estatístico STATA 14.0, apresentando frequências relativas e absolutas. O número total de encaminhamentos realizados no período foi de 3.945, a maioria destes para pessoas do sexo feminino e com idade média de 51,2 anos. Do total de encaminhamentos, em 60,2% (2.377) dos casos o atendimento não se concretizou. Nas situações que resultaram em atendimento, em 77,6% (1.221) dos casos, este ocorreu no mesmo ano do encaminhamento. A maioria dos encaminhamentos foram para clínicas de atendimento integrado, indicando um acúmulo de necessidades terapêuticas. Esse tipo de avaliação é fundamental para o planejamento estratégico de um serviço de saúde, pois permite fazer uma análise e mapeamento do fluxo dos pacientes, além de uma reflexão sobre as possibilidades de acesso para as pessoas que buscam o serviço.
A Quantum Computer in a “Chinese Room”

Pattern recognition is represented as the limit, to which an infinite Turing process converges. A Turing machine, in which the bits are substituted with qubits, is introduced. That quantum Turing machine can recognize two complementary patterns in any data. That ability of universal pattern recognition is interpreted as an intellect featuring any quantum computer. The property is valid only within a quantum computer: To utilize it, the observer should be sited inside it. Being outside it, the observer would obtain quite different result depending on the degree of the entanglement of the quantum computer and observer. All extraordinary properties of a quantum computer are due to involving a converging infinite computational process contenting necessarily both a continuous advancing calculation and a leap to the limit. Three types of quantum computation can be distinguished according to whether the series is a finite one, an infinite rational or irrational number.
Neuron-specific enolase as a diagnostic marker of chronic gastroduodenitis in children
Authors: Dombayan S. KH. , Kharitonovа L. А. , Panova I. V.
Published: May 2020

Objective: to assess the nature of changes in the level of neuron-specific enolase (NSE) in children suffering from chronic gastroduodenitis, depending on the severity of the disease, gender and physical development indicators.

Materials and methods. The study group included 154 children aged 8–15 years with chronic gastroduodenitis. The main group includes children with superficial gastroduodenitis (group I) and erosive gastroduodenitis (group II). The control group consisted of 56 healthy children. All children underwent an assessment of physical development. The serum NSE level was determined by enzyme-linked immunosorbent assay. It was revealed that the main parameters of the physical development of children from the control group exceeded the values of similar parameters of children of the main group. High NSE values were established in children with chronic gastroduodenitis in comparison with the control (p≤0.01). The NSE level in boys exceeded the value of the indicator in girls in the main group and in the control group. The level of NSE in girls of the main group exceeded the value of NSE in healthy girls (p≤0.05). Studying the level of NSE taking into account gender and the severity of the pathological process revealed higher rates in boys with erosive gastroduodenitis compared with the control group (p≤0.05). In the group of children with erosive gastroduodenitis, higher NSE rates were found in boys compared with girls (p<0.05).

Conclusions: A high level of NSE in children with erosive gastroduodenitis and revealed gender differences in NSE concentrations in blood serum indicate the possible role of this indicator in the development of severe forms of the disease and do not exclude the possible association of the effects of this enzyme with the function of sex hormones. The quantitative values of NSE for predicting the development of chronic gastroduodenitis in children are established.

National-Scale Forest Soil Carbon Characterizing Using Reflectance Spectroscopy
Authors: Gholizadeh Asa , Rossel Raphael A. Viscarra , Saberioon Mohammadmehdi , Kratina Josef , Boruvka Lubos , Pavlu Lenka
Published: May 2020

Any strategy to change the Carbon (C) pool has a substantial effect on the functionality of numerous ecosystem functions, the detachment of Soil Organic Carbon (SOC), the atmospheric carbon dioxide (CO2) concentration, and climate change mitigation. As the largest amount of the world's C is stored in forests soils, the importance of forest SOC management is highlighted. The total SOC in a forest varies not only laterally, but also vertically (i.e., with depth). However, the SOC storage of different forest soil horizons has not been investigated in a national scale thoroughly, despite their potential to frame our understanding of soil function. Visible--Near Infrared (vis--NIR) reflectance spectroscopy enables rapid examination of the horizontal distribution of forest SOC, overcoming the limitations of traditional soil assessment methods. This study aims to evaluate the potential of vis--NIR spectroscopy in characterizing and predicting the SOC content of organic and mineral horizons in forests. We investigate 1080 forested sites across the Czech Republic at five individual soil layers, representing the Litter (L), Fragmented (F), and Humus (H) organic horizons, as well as the A1 (depth of 2--10 cm) and A2 (depth of 10--40 cm) mineral horizons (for a total of 5400 samples). We, then, use Support Vector Machines (SVMs) to classify the soil horizons based on their spectra and also to predict the SOC content of (i) the profile (all organic and mineral horizons together), (ii) the combined organic horizons, (iii) the combined mineral horizons, and (iv) each individual horizon separately. The models are validated using 10-repeated 10-fold cross validation. The results show that there is at least more than seven times as much SOC in the combined organic horizons, compared to the combined mineral horizons, with more variation in the deeper layers. The SVM with radial based kernel is a reliable classifier for classification of soil horizons, with Correct Classification Rate (CCR) of 70% and Kappa coefficient of 0.63. All individual horizon SOCs are successfully predicted with low error and with R2 values higher than 0.63. However, the prediction accuracies of the F and A1 models are greater, compared to others (R2~0.70 and very low-biased spatial estimates). We conclude that the modelling of SOC with vis--NIR spectra in different soil horizons of highly heterogeneous forests in the Czech Republic is practical. This study provides an example of how general pedological knowledge can be used to define depth functions of SOC for forested sites.
Unification of Gauge Forces and Gravity using Tangled Vortex Knots and Entanglement Dynamics
Authors: Guha Majumdar Mrittunjoy
Published: May 2020

In this paper, the statistics of excitation-tangles in a postulated background ideal-superfluid field is studied. The structure of the Standard Model is derived in terms of tangle vortex-knots and soliton. Gravity is observed in terms of torsion and curvature in the continuum. In this way, non-linear dynamics and excitations give rise to a unified field theory as well as a Theory of Everything. As a result of this unification, spacetime and matter are shown to be fundamentally equivalent, while gauge fields arise from reorientation and excitations of the the fundamental underlying field. Finally, the equivalence of topological and quantum entanglement is explored to posit a theory of everything in terms of long- and short-range entanglement between fundamental quantum units (bits) of information.
Does the surveillance paradigm provide evidence for unconscious evaluative conditioning? A Bayesian perspective
Authors: Kurdi Benedek , Ferguson Melissa
Published: May 2020

In evaluative conditioning (EC), a neutral conditioned stimulus acquires the valence of an intrinsically valenced unconditioned stimulus as a result of repeated pairings between the two. Evidence for EC in the absence of awareness of the pairings has been provided using the surveillance paradigm (Olson & Fazio, 2001). In this commentary, we report a Bayesian reanalysis of data from a multi-lab replication of this paradigm (Moran et al., 2020). Unlike the original frequentist analyses, we conclude that the replication does not provide convincing evidence in favor of unconscious EC under any of the exclusion criteria, including the ones originally used by Olson and Fazio (2001). Moreover, when informative priors relying on the totality of meta-analytic evidence are used, three of four analyses provide evidence against an effect. This commentary highlights the benefits of using Bayesian analytic approaches and cautions against inferring the presence of unconscious EC in the surveillance paradigm.

Do national funding organizations properly address the diseases with the highest burden? - Observations from China and the UK
Authors: Zhang Lin , ZHAO Wenjing , Liu Jianhua , Sivertsen Gunnar , HUANG Ying
Published: May 2020

Recent years have witnessed an incipient shift in science policy from a focus mainly on academic excellence to a focus that also takes into account “societal impact”. This shift raises the question as to whether medical research has given proper attention to the diseases imposing the greatest burden on society. Therefore, with the aim of identifying correlations between research funding priorities and public demand in health, we examine grants issued by the major medical research funding bodies of China and the UK during the decade 2006-2017 and compare the focus of their funded projects with the diseases that carry the highest burden of death, risk, or loss of health. The results indicate that the funding decisions of both nations do correspond to the illnesses with the highest health impact on their citizens. For both regions, the greatest health concerns surround non-communicable diseases, and neoplasms and cardiovascular disease in particular. In China, national health priorities have remained focused on these illnesses for the benefit of its own population, whereas the UK has funded a wider variety of research, extending to projects with impacts outside its borders to some developing countries. Additionally, despite an increased incidence of mental illness and HIV/AIDs in China, there is evidence that less priority has been given to these conditions. Both of these health areas seem to require more attention from China’s national funding agencies and the society in general. Methodologically, this study can serve as an example of how to conduct analyses related to public health issues by combining informetric methods and data with data and tools from other fields, thereby inspiring other scientometrics studies.
If quantum mechanics is the solution, what should the problem be?
Authors: Penchev Vasil Dinev
Published: May 2020

The paper addresses the problem, which quantum mechanics resolves in fact. Its viewpoint suggests that the crucial link of time and its course is omitted in understanding the problem. The common interpretation underlain by the history of quantum mechanics sees discreteness only on the Plank scale, which is transformed into continuity and even smoothness on the macroscopic scale. That approach is fraught with a series of seeming paradoxes. It suggests that the present mathematical formalism of quantum mechanics is only partly relevant to its problem, which is ostensibly known. The paper accepts just the opposite: The mathematical solution is absolute relevant and serves as an axiomatic base, from which the real and yet hidden problem is deduced. Wave-particle duality, Hilbert space, both probabilistic and many-worlds interpretations of quantum mechanics, quantum information, and the Schrödinger equation are included in that base. The Schrödinger equation is understood as a generalization of the law of energy conservation to past, present, and future moments of time. The deduced real problem of quantum mechanics is: “What is the universal law describing the course of time in any physical change therefore including any mechanical motion?”

Published: May 2020

The study presents an analysis of the frontal impact of a Dodge Grand Caravan car colliding with different obstacles - a rigid barrier, for full and 50 % overlaps, and a pole with 0.5 m. diameter. Simulations were performed using a V-Sim 4 program at three data sets: default data offered by the program, data established by experts on the basis of their experience and identified on the basis of impact simulation via a LS-Dyna program. The results obtained showed that the attainment of a precise simulation is possible only when the data of V-Sim program is formulated in accordance with an advanced MES analysis. This usually pertains to cases when there is no full overlap of the vehicle body in connection with the obstacle. The results of this work may offer some directions for the development of this type of simulation program. They also show users how important it is to provide accurate input data to achieve reliable calculation results.

Identification of the concrete damage degree based on the principal component analysis of acoustic emission signals and neural networks
Authors: Wang Yan , Jie G. , Na W. , Chao Y. , Li Z. , Jun C. L.
Published: May 2020

This paper aims to improve the calculation efficiency and accuracy of concrete damage degree identification, and then to analyze the damage mechanism of concrete damage. First, the correlation analysis and principal component analysis of 15 characteristic parameters of acoustic emission signals accompanying concrete uniaxial compression and splitting damage process are performed through which the dimension is reduced into 5 non-correlated principal components. Then, based on the analysis of the relationship between each principal component and the damage and cracking mechanism of concrete, the damage degree of concrete is identified as an input variable of the BP neural network. The results show that the 5 principal components effectively eliminate redundant information and carry information on the failure mechanism of concrete damage and the damage process. Principal component analysis and the neural network are used to achieve the accurate recognition of acoustic emission parameters and the degree of concrete damage.
Multi-response optimization of AA 8011 and 12 wt.-% fly ash composites
Authors: Magibalan S. , Senthilkumar P. , Senthilkumar C. , Prabu M.
Published: May 2020

The present research work is focused on the production of aluminum alloy 8011 with 12 wt.-% fly ash composite by using the stir casting method. A three-level central composite design experiment is developed using response surface methodology (RSM) with various parameters. Load, time and sliding velocity are varied in the range of (5-15 N), (5-15 min) and (1.5-4.5 m × s-1), respectively. Dry sliding wear tests are performed as per the experimental design using a pin-on-disc at room temperature. This paper describes how optimization studies were carried out on a dry sliding wear process with multi-response characteristics based on MCDM using the TOPSIS approach. The process parameters, load, time and sliding velocity are optimized with multi-response characteristics, including the wear rate (WR), and the coefficient of friction (COF). A sensitivity analysis is also carried out and compared with the relative impact of input parameters on wear behavior in order to verify the measurement errors on the values of the uncertainty in estimated parameters. The experimental results indicate that the multi-response characteristics of aluminum alloy 8011 with 12 wt.-% fly ash composite used during the wear behavior process can be enhanced through the TOPSIS method.

Published: May 2020

In this study, DAMASK was used to model and elucidate the microstructural deformation behavior of sintered X3CrMnNi16-7-6 TRIP steel. The recently developed TRIP-TWIP material model was used within the DAMASK framework. Material optimization was performed using the least computationally expensive method, which yielded the desired results. The physical parameters of the material model were identified and tuned to fit the experimental observations. This tuned material model was used to run simulations utilizing 2D EBSD data. The local deformation, transformation, and twinning behaviors of the material under quasi-static tensile and compressive loads were analyzed. The results of this are in good agreement with previous experimental observations. The phenomena of dislocation glide, twinning, martensitic transformation, stress evolution, and dislocation pinning in different deformation stages are discussed.
Influence of nanostructured Cu on the mechanical properties of Cu–MWCNTs composites
Authors: Kumar Lailesh , Sahoo Santosh Kumar , Alam Syed Nasimul
Published: May 2020

In the present investigation, Cu-multiwalled carbon nanotubes (MWCNTs) nanocomposites were developed through mechanical milling using nanostructured Cu as a matrix and MWCNTs as nanofillers. The influence of nanostructured Cu on the microstructure, microhardness, and wear behavior of Cu-MWCNTs nanocomposites was also studied. The crystallite size of nanostructured Cu powder via mechanical milling for 25 h was found to be 16 nm. The major challenge associated with the development of Cu-MWCNTs nanocomposites is the uniform dispersion of the CNTs in the Cu matrix, which was addressed by incorporating nanostructured Cu, leading to the homogeneous distribution of CNTs and good bonding between the CNTs and the Cu matrix. A significant improvement in relative density and microhardness with <3 wt.% MWCNTs was observed compared to pure asreceived Cu and its composites. The hardness of Cu-3 wt.% MWCNTs nanocomposite developed using nanostructured Cu were achieved at <800 MPa, which is about 2.3 times higher than that of the as-received Cu sample (~ 359 MPa). The significant increment in mechanical and wear properties mainly originates from fine-grain strengthening effects and solid solution strengthening. The wear mechanisms in the various nanostructured Cu-MWCNTs composites were studied in detail and oxidation wear was identified as one of the main wear mechanisms.

The effects of the Zn content on the mechanical and corrosion properties of MgZnMnCa alloys were investigated. The results revealed that with increasing Zn content up to 4 wt.%, the Mg-4Zn-0.2Mn-0.2Ca (wt.%) alloy after solution treatment at 400°C for 24 h (ZM40-S) exhibited a volume fraction of 1.56 ± 0.05 (vol.%) of secondary phases with an average grain size of 83.6 ± 1.6 µm. This alloy in the at-cast condition exhibited indentation hardness (Hit) of 657.1 ± 17.8 MPa, which increased to 723.5 ± 29.8 MPa after solution treatments. In addition, the alloy also exhibited a Vickers hardness value of 66.8 ± 2.7 HV and an elastic modulus of 33.8 ± 0.6 GPa, close to the values for human bone. Further, the corrosion properties of this alloy were analyzed: it exhibited a cathodic polarization curve attributed to a hydrogen evolution reaction and an anodic curve corresponding to a passivation tendency, indicating the formation of an oxide layer at the surface; further, its corrosion rate was 0.23 mm/year.

The article examines the issues related to state regulation of the economy during the crisis, considered the problems of determining the feasibility and effects of state regulation in times of crisis, proved that the market economy, due to its inherent weaknesses, is prone to causing the crisis. This process is objective and cyclical. In the past decade, the number of crises, including the world, has increased significantly, which is associated with the growth of the financial sector. Permanent repetition of negative developments in the financial system and has a direct impact on the economy, which proves the need to strengthen state regulation in this sphere. The methods that can be used by different countries, in order to overcome the crisis in the economy was analyzed. It is proved that the administrative methods of crisis management, as a rule, are used in countries where market laws are not effective enough. In turn, in the economically more developed countries are used market-based instruments of crisis management. The features of state regulation of economy in some countries during the recent global economic crisis was investigated. It was found that, in spite of such a list of measures to counter the crisis in the developed countries, they have some differences, primarily related to the specific characteristics and structure of the economy. It was determined that in all the years of independence, the national economy has repeatedly been in crisis, at the same time, even though the experience gained so far has not created an effective mechanism to counter these negative phenomena.

This article is presented information about electron microscopic characteristic the angioarchitectonics of hemomicrocirculatory white rat skin net in experimental streptozotocin-induced diabetes mellitus. Was used in the experiment 30 adult white male rats weighing 120-130 grams, which were maintained on a standard diet, had free access to food and water under normal conditions. The insulin-dependent form of type I diabetes mellitus was modeled by a single intraperitoneal injection of streptozotocin from Sigma at a rate of 7mg per 100g of body weight of the animal (prepared on 0.1M citrate buffer, pH = 4.5). The development of experimental diabetes mellitus during 4 weeks was monitored by observing an increase in blood glucose, which was measured by the glucose oxidase method. Studies were performed on rats with glucose levels of 12.00 mmol/l and above. The experiment was carried out in accordance with the provisions of the European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Scientific Purposes (Strasbourg, 1986), Council of Europe Directive 86/609 / EEC (1986). Rats were removed from the experiment by an overdose of intraperitoneal anesthesia using sodium thiopental (calculated at 25 mg / kg body weight of the animal). Applying the method of electron microscopy (the study and photographing of the material was carried out on an electron microscope EM-100 AK at an accelerating voltage of 75 kV and magnification 6000-8000 times). As a material for this examination, the skin intact from the internal surface of the thigh and the back of the white rats was used. The study showed that after 2 weeks of diabetes occure gradually and are progressing alterations of the skin's hemomicrocirculatory bed of white rats, which characterised mainly by small spasm of some vessels. The wall of the most vessels still had normal structure but revealed a narrowing of the capillaries due to the protrusion of the nuclear zone of the endothelial cells. After 4 weeks of the experimental streptozotocin-induced diabetes mellitus were already observed reconstruction practicaly all skin's microvessels of white rats. The lumen of the capillaries became irregular. The contours of the nuclei of endotheliocytes were elongated with an uniform homogen chromatyn, which is concentrated in lumps, thickened bazal membrane, observed proliferation of endothelial cells, which leads to narrowing of the lumen of blood vessels. At the end of the experiment, we observe the inclusion of compensatory properties of the organism - the wall of blood vessels of the hemomicrocirculatory bed of the skin thickens, while the lumen of the microvessels become narrows. The results of investigation can be used in the practice medicine for diagnosis and treatment of skin's diseases in diabetes mellitus.

The article is devoted to the review of educational literature published in the printing houses of the largest Muslim regions of the Russian Empire in the XIX - beginning of the XX century. The author makes conclusion about general trends in religious education of Muslims, the main elements of which was a maktab (elementary school) and madrasa (high school), and also lists branches of science, that were an obligatory part of the student’s program. Is was noted that madrasas of each region had some sort of program, distinguished by in-depth study of a particular science. It is indicated that the superiority in the publication of Muslim educational literature in the Russian Empire in this period belonged to Kazan, which became the center of Muslim printing. In Daghestan and Turkestan, where Arab graphic printing firmly took its place in the early twentieth century, textbooks for Muslim schools were also produced repeatedly and in large editions, as well as sold for affordable prices. The author lists and characterizes the most popular textbooks that were widely used in these regions, and concludes that educational literature, prayer books and ritual manuals were equally in demand by the local population.
