Good and bad luck of a computer project
Authors: Malinetskii Georgii Gennadyevich 
Published: June 2021

A computer project in the world and in Russia is now usually viewed as an economic, technological or military one. At the same time, it is a global social project. From the theory of the humanitarian and technological revolution, it follows that at the current point of bifurcation, its results can determine the path of humanity to the future. I show that the results of this project reflect the readiness of civilizations for socio-technological change. The COVID-19 pandemic turned out to be a test for social imperatives and had a huge impact on computer reality in the formation of a new sociality. Book by K. Schwab, T. Mallerert “COVID-19: The great reset” represents a variant of such sociality. The analysis presented in this work shows the unacceptability of the proposed changes for the world of Russia. A study of large-scale computer projects in Russia and Belarus shows the need to bring them to a new sociocultural level, much higher than the current one. The unsuccessful experience of mass e-education in the Union State confirmed the imperative of Norbert Wiener: “Render unto man the things which are man’s and unto the computer the things which are the computer’s”. This should, apparently, be a reasonable line of behavior in organizing joint actions of people and machines.

Published: June 2021

The peculiarities of software product testing processes while working in the Scrum-team were studied. The types of testing characteristic of the flexible testing technique are singled out, that make it possible to make the testing process constantly integrated into teamwork, both at the stage of requirements formation and design, and at the stage of coding and generation of test sets. This is possible by making the tester's recommendations in the process of creating user stories, planning the release of the software version in terms of testing and defects, planning a sprint based on user stories and defects, performing a sprint with continuous testing, regression testing after sprint ends and reporting of results of testing. The article highlights the stages of the flexible testing process in the Scrum team. It is proposed to automate the process of flexible testing for a training team project in the Visual Studio software environment based on Team Foundation Server. Author demonstrates an example of automation of the process of flexible testing by dividing it into four quadrants to comply with the principles of working on a flexible methodology of software development. In the first quadrant there is a study of the quality of the internal code of the software product, the modular testing. To implement modular testing in Visual Studio, a new solution is created in order to generate a class for testing, where the conditions for testing are prescribed in the body of the class. The second quadrant implements the principles of system testing. At this stage the features of creating such a test artifact as test cases are demonstrated. That provides for the fulfillment of certain conditions to verify the functionality of the developing software product; linking between created test cases to user stories presented as team project tasks Product Backlog. The study demonstrates an example of manual testing using a special tool Microsoft Test Manager, which allows you to create plans, add and update test cases, perform manual tests. In the third quadrant, it was performed a trial test in Microsoft Test Manager and it was created another test artifact - error reports. The fourth quadrant automatically tests non-functional software requirements.

Online game is one of the most popular leisure activity for adolescents. Playing it excessively can lead to addiction. Once addicted, behavior problems arise and at a certain level of addiction, psychological treatment will be needed. The aim of this study is to describe online gaming addiction in terms of four levels of addiction. The participants are 41 high school students (12-14 years old) who lived in Jatinangor. They are active players in online games using mobile phones, computers, or other media. Data were collected using an open-ended questionnaire than qualitatively analysed by the way of thematic analysis. Result shows that participants mostly perceived playing online games as a pleasurable and rewarding activity (recreational level of addiction). In this level, there are negative impacts that occur when they are playing online games, but the impacts disappear when they stop playing an online game. In at-risk level, participants feeling the rewarding effects (e.g. stress release). Participants accept when their parents start complaining about their gaming behavior. In problematic use level, the gaming behavior is increasingly done alone and often dismissed parents’ concern about their gaming behavior. In fully addict level, only the amount of time for playing online games reported (8 hours per day).

Abstract
From the beginning of civilization, the media for storing data have been continuously evolving from such as stone tablets, animal bones and bamboo tablets to paper, with improvements on data density over time. Since the invention of electronics in the last century, the percentage of data stored in digital form has been increasing rapidly to almost 100% recently. Moreover, the amount of data generated has been increasing exponentially, from several ZB in 2008 to an expected 74 ZB in 2021, causing a much increased demand for data storage correspondingly. Most of the digital data are stored in physical media such as hard drives. In addition, many of the data are rarely accessed and are archived on reels of magnetic tapes. However, the physical thickness of the tapes and the size of magnetic domains limit the maximum data density, which is expected to reach a plateau soon. Furthermore, data in old tapes need to be copied onto new tapes regularly, as the magnetic tapes can normally last for ten to twenty years only. This process is time-consuming and expensive. Hence, next-generation media that can store digital data with a much higher data density and durability are needed.Here we report the use of peptide sequences for digital data storage, a method that has not been reported before. The data-bearing peptides are commercially synthesized, and the data retrieval process is described here. As an example, we stored one dataset consists of (i) 848 bits of ASCII formatted text in 40 peptides, and (ii) another dataset consists of 13752 bits of the “silent night” music in MIDI format together with its title in ASCII format in 511 peptides. These files are available in Supplementary Files section.

Published: June 2021

Abstract
Biomass accounts for the largest proportion of rural solid waste with high moisture content, which affects the thermal treatment process. This paper studied the effect of steam on the pyrolysis tar of microcrystalline cellulose (MCC) by a two-stage fixed bed. The experiments had been carried out under different steam/feedstock mass ratios (S/F= 0, 0.8, 1.2, 1.6) when the first stage was at 600℃, and the second stage was at 800 ℃. The tar content in the syngas was reduced effectively from 6.68% to 2.30% when the S/F was from 0 to 1.6. Under the four S/F conditions, aromatic compounds accounted for more than 80%, which was the largest proportion of tar products. Significantly, formic acid phenyl ester (FAPE) decreased obviously with the growth of S/F. Besides, when the steam content was excessive, the MAHs, such as phenols and indenes, could be further cyclized and aromatized to form PAHs. To further study the removal mechanism of tar, the FAPE was investigated by density functional theory (DFT). It was concluded that the O3-C4 bond of FAPE was most likely to be attacked by the H2O molecule to form phenol, CO2, and H2 directly, among the four possible paths.

Published: June 2021

Abstract
The novel deep learning image reconstruction (DLIR) is known to change its image quality characteristics according to object contrast and image noise. In clinical practice, computed tomography (CT) image noise is usually controlled by tube current modulation (TCM) to accommodate changes in object size. This study aimed to evaluate the image quality characteristics of DLIR for different object sizes when in-plane noise is controlled by TCM. We used Mercury 4.0 phantoms with different object sizes. Phantom image acquisition was performed on a GE Revolution CT system to investigate the impact of the DLIR algorithm compared to standard reconstructions: filtered back projection (FBP) and hybrid iterative reconstruction (hybrid-IR). For image quality evaluation, the noise power spectrum (NPS), task-based transfer function (TTF), and detectability index (d') were determined. The NPS of DLIR was very similar to that of FBP, and the information in the high-frequency region was maintained. In terms of TTF, DLIR showed higher resolution than hybrid-IR at low- to medium-contrast (Δ50, Δ90HU), but not necessarily higher than FBP. At the simulated contrast and lesion size, DLIR showed higher detectability than hybrid-IR, regardless of the phantom size. In this study, we evaluated a novel DLIR algorithm by reproducing clinical behaviors. The findings indicate that DLIR produces higher image quality than hybrid-IR regardless of the phantom size, although it depends on the reconstruction strength.

Published: June 2021

Abstract
With the increasing emphasis on the toxicity of ionic liquids, it is imperative to develop detection methods for ionic liquids in complex environments. A new method for the analysis of hydroxyl functionalized imidazolium ionic liquids in complex environmental water samples by using ion chromatography and solid-phase extraction was developed. Under the selected chromatographic conditions, the complete separation of the two analytes was achieved in 14.0 min. The linear and repetitive data of the approach for the analysis of the two cations by ion chromatography meet the requirements of quantitative analysis. The extraction of [HEMIm]+ and [HPMIm]+ in water samples by ion-exchange solid-phase extraction and reversed-phase solid-phase extraction was compared. The results show that the enrichment and purification of two target cations can be better achieved using ion-exchange solid-phase extraction approach, and the enrichment multiple was 50 times. The method was used to determine the target cations in two river waters. The recovery of standard addition was between 82.5% and 96.0%, the detection limit was less than 0.01 mg/L, and inter-assay RSD was less than 2.5%. The method is simple, accurate and reliable. It is suitable for the determination of hydroxyl functionalized imidazolium ionic liquid cations in environmental water samples.

Published: June 2021

Abstract

The photovoltaic (PV) module is equipment that converted sunlight energy to electrical energy. To show the behavior of this device, a mathematical model should be presented. The well-known single-diode and double-diode models were utilized to demonstrate the electrical behavior of the PV module. Moreover, the single and double-diode models have been explained and simulated to study the difference between them under different weather conditions. Furthermore, the mathematical analysis of these models are carried out based on their equivalent circuits. Since, the "Matlab/Simulink" is considered as one of the major software for modeling, analyzing, and solving the dynamic system real problems; it has been used to model and simulate the PV models. In this work the "Mux." and "Fcn." functions in the "Matlab/ Simulink Library" are used which is considered a simple and precise procedure to show the I-V and P-V characteristics. As a result, more accurate results of the I-V and P-V curves have been obtained by the double-diode model compared to the single-diode model. Experimentally, the monocrystalline NST-120W PV module is used to validate the proposed work. The laboratory devices of lux meter, thermometer, ammeter, and voltmeter are used to see the practical results and show the performance of the PV module for different weather conditions. Finally, the experimental voltage, current and power are obtained for the various values of irradiance and temperature through a variable resistive load to obtain the I-V and P-V graphs.

Published: June 2021

Abstract
Streptococcus suis (S. suis) has been well-recognized as a zoonotic pathogen worldwide gearing up a great risk to the public health. In this study, an S. suis LSM178 strain with serotype 2 and novel multi-locus sequence type of 1005, isolating from a patient, was interpreted for the pathogenicity by its genetic information. LSM178 was more efficiently invasive to Caco-2 cells than SC19 and P1/7. Phylogenetic analysis showed that LSM178 clustered with highly virulent strains including all human strains and epidemic strains. These serotype 2 S. suis from China shared exclusively the typical virulence characteristics including the maximum (95/96) virulent factors and type I-89 K Pathogenicity Island. Further, groups of genes were identified to distinguish these highly virulent strains from other generally virulent strains, emphasizing the key roles of genes modeling transcription, cell barrier, replication, recombination and repair on the high pathogenicity for highly virulent strains. Additionally, LSM178 contains a novel prophage conducive potentially to pathogenicity. These characters would contribute to deeply studying the pathogenic mechanism and virulence drift of human pathogenic S. suis.

Abstract
BackgroundThe first month of life is the most critical in a child’s heath because it is associated with the highest risk of adverse health outcomes. In Tanzania the risk of adverse health outcomes in preterm infants is five times higher compared to term infants.The objective of this study was to assess common adverse health outcomes and compare the risk of such outcomes between preterm and term infants, in Tanzania, within the first 28 days of life.MethodsThis was a case-control study involving preterm (cases) and term (controls) infants delivered at the Muhimbili National Hospital between August and October 2019 . About 222 pairs of cases and controls were reviewed for their medical records. Logistic regression was used to compare the risk of neonatal outcomes between the study groups. Statistical significance was achieved at P-value < 0.05 and 95% confidence interval.ResultsPreterm infants have an increased risk of mortality (OR = 7.2, 95% CI: 3.4-15.1), apnea (OR = 4.7, 95% CI: 3.4-15.1), respiratory distress syndrome (OR = 4.8, 95% CI: 3.2-7.3), necrotizing enterocolitis (OR = 5.5, 95% CI: 1.2-25.3), anemia (OR = 4.3 , 95% CI: 2.8-6.6), pneumonia (OR = 2.7, 95% CI: 1.6-4.6) and sepsis (OR = 2.6, 95% CI: 1.7-3.9) in the first month of life compared to term infants. No differences in the risk of intraventricular hemorrhage, bronchopulmonary dysplasia, patent ductus arteriosus and jaundice were observed between preterm and term infants. ConclusionThe findings of this study informs the Tanzanian health sector about the most common and high risk neonatal outcomes in preterm infants. Additionaly, for promoting neonates' health, the health sector needs to consider preventing and treating the most common and high risk adverse neonatal outcomes in preterm infants.

Published: June 2021

Abstract
Background: Sister Mary Joseph’s nodule is a rare but important physical finding as it is a sign of an advanced stage of malignancy.Case presentation: This is a case of an apparently clinically well but immunodeficient 62-year- old African woman whose main complaint was an enlarging violaceous discharging umbilical nodule. A focused history and physical examination complemented by an abdominal computerized tomography (CT) scan was suggestive of an umbilical cutaneous manifestation (Sister Mary Joseph’s nodule) of an underlying disseminated ovarian malignancy. This was confirmed histologically by an excision biopsy of the umbilical nodule.Conclusions: Sister Mary Joseph’s nodule is an important differential diagnosis for an umbilical nodular lesion as it is a sign of advanced malignancy with a generally poor prognosis.

Abstract
Background: Paying particular attention to the health of adolescents, especially girls, is one of the millennium development goals, the improvement of HPB in female adolescents is necessary. Therefore, this study aimed to determine the effect of the empowerment-based e-learning program on HPB in female adolescents.The present study was of quasi-experimental type (educational intervention) in which 80 middle school and high school female students participated. Data collection tools included the Questionnaire of Demographic Characteristics and the HPB Questionnaire (the Health Promoting Lifestyle Profile II (HPLP II)). First, the pretest was performed using the research tool in both intervention and control groups. After performing the pretest, the empowerment model was performed according to the needs, wants of the research samples, and based on the triple steps (perception of threat, problem-solving, and assessment) for the intervention group. Eight weeks after the intervention, the questionnaire was completed again in both groups. Results: The implementation of the educational program led to increased mean scores in the dimensions of HPB, including health responsibility, physical activity, nutrition, and interpersonal relationships in the intervention group, but spiritual growth and stress management had no significant change (p>0.001). However, in the control group, no statistically significant change was observed in any of the dimensions of health-promoting behaviors.Conclusion: The results of this study showed that empowerment-based e-learning can be effective in changing the behavior of female adolescents towards healthy behaviors. Therefore, this method is recommended as an effective educational approach to improve adolescent health-promoting behaviors.

Abstract
Background:Triple-negative breast cancer (TNBC) is a high-risk breast cancer subtype, which accounts for 15% to 20% of all breast cancers and generally has a poor prognosis. TNBC patients have high recurrence post-surgery and high risk of metastasis to other organs. The tumor microenvironment (TME) plays important roles in the carcinogenesis, development, and metastasis of tumors. Methods: This study aimed to investigate the effects of immune and stromal cell-related genes on TNBC prognosis. The ESTIMATE algorithm was used to calculate the immune/stromal scores of TNBC samples from the GEO database. The samples were divided into high- and low- score groups and the differential expression genes were identified using the limma package within R. Functional enrichment and protein-protein interaction (PPI) network analyses revealed that these genes are primarily involved in immune responses. Results:Survival analysis in both GSE21653 and KM-plotter website showed that 36 genes were significantly related to disease-free survival (DFS) of TNBC. Another survival analysis by R package survival in GSE58812 indicated that 14 genes of 36 were greatly interrelated to DFS of TNBC. Moreover, the expression levels of some of these genes were verified through immunohistochemical staining and RT-qPCR. Finally, four genes importantly associated with TNBC prognosis were identified with Cox-LASSO analysis. Time-dependent receiver-operating characteristic (ROC) analysis displayed an area under the curve (AUC) of 0.95 for one-year survival rate, indicating the four genes performed very well for prognosis prediction. Conclusions:In conclusion, we identified four genes, including BIRC3, CD8A, GNLY and TRIM22, that are possibly associated with the TME and are potential prognostic and therapeutic markers of TNBC.
