Published: January 2023

Purpose: The study of the problem of passenger traffic forecasting for high-speed railways given peculiarities of regional development and competition in passenger transportation market in Russian Federation conditions. The influence of a large number of different factors on passenger traffic volume formation is the main reason for the difficulty of obtaining reliable forecasts of passenger traffic in the long term. Based on the analysis of Russian and foreign scientific papers, devoted to the problem under study, the most significant factors were identified from ones’ variety: population, per capita income, gross domestic and regional products. The analysis showed that scientists ambiguously assess the impact of gross regional product on passenger traffic volume. The authors investigated the relationship between the volumes of passenger traffic and gross regional product on directions of being projected high–speed railways Moscow - St. Petersburg and Moscow — Kazan. As a result, the sections of gross regional product with the greatest degree of influence on passenger traffic were identified. Also, in modern conditions, concurrence in passenger transportation market has significantly increased which mainly determines the distribution of passenger traffic by transport kinds. Methods: System analysis, correlation and regression analysis, time series analysis. Results: The obtained results showed that in market conditions, because of the dynamism and uncertainty of population’s demand for transport services which is caused by a passenger’s choice of traffic method depending on transportation travel time, cost and comfort; the complexity of forecasting passenger traffic has increased. Two variants of passenger traffic forecasting methodology for high-speed highways are proposed in view of competition in the passenger transportation market. Practical significance: The application of a mathematical model for forecasting passenger traffic, taking into account the peculiarities of Russian Federation regions development and the competition between different kinds of passenger transport, will allow to obtain a reliable estimate for promising passenger traffic volumes that will provide for the reduction of investment risks in the construction and operation of capital-intensive high-speed railways.

Published: January 2023

Purpose: Calculated substantiation of cavityless drain structure that provides for effective draining of poorly permeable soils. Hydraulic calculation methodology of composite profile cavityless drain, laid with a slope but without inclusion thitherwards of a drainage pipe, was developed earlier. Drainage pipe reinforces drainage capability of cavityless drain with the preservation of all its other advantages. Methods: Known differential equation of liquid filtration in a soil is used. It’s of special importance that the calculation method may be used at all modes of water movement in a drainage: laminar, transient or turbulent. The dependencies substantiated with experiments, held by Northern Scientific-Research Institute of Hydrotechnique and Melioration, were applied for transient and turbulent modes. The complex form of drainage transection is taken into account with the help of special coefficient which leads it to equivalent by area rectangular section. It’s proved that such transfer doesn’t lead to significant inaccuracy of results obtained. Results: Dependencies have been obtained allowing to calculate consumptions, flowing along drain cavityless part and along drain pipe. If drain is long, it’s feasible to divert a water periodically from it in lateral direction by collectors. Dependencies are derived which according to, the distance between intermediary collectors, whereto a water comes from drains that’re laid with a slope, and the water depth in drain cavityless part in characteristic sections are defined. Practical significance: Cavityless drainage is applied in agriculture, in the systems of engineering protection from environmental sinking and pollution. Cavityless drains of composite profile have attracted railwaymen’s attention providing effective draining of subgrade, they simultaneously increase its bearing capacity. Its application is especially effective on poorly permeable soils when laying in the zone of seasonable freezing of soils.

Practical importance: The proposed method can be used when adjusting fuel equipment after the repair of a diesel engine as with electronic fuel supply control systems as well as with hydromechanical fuel equipment. The use of the given method excludes the necessity of temperature measurement for exhaust gases and flash pressure measurement in cylinders for fuel equipment adjustment that’s especially important for high-speed diesel engines which cylinder heads’ construction doesn’t provide for indicator cocks. In the engines equipped with electronic fuel control systems, the use of IAV signal spectrum low-frequency band energy as a diagnostic parameter makes it possible to automate fully the equalization process for cylinder load. The result of the proposed method application will be the reduction in the duration and labor intensity of diesel locomotives rheostat tests as well as the rise in diesel locomotives reliability and efficiency at the expense of uniform loading of diesel cylinders.

Authors: Fofanova Elizaveta
Published: January 2023

Serotonin (5-HT) is crucial molecule in animal kingdom. It is involved in control of multiple processes. It might act via transmembrane receptors or via postranslational protein modification (serotonylation). D. gyrociliatus is a marine worm-like invertebrate with quite short lifespan. In this study lifetime experiments were performed. We incubated freshly laid eggs, adult females lifelong in HTP, PCPA and cystamine. Every week we monitored the survived individuals. This was lifelong (about 5 moth) monitoring. The survival analysis demonstrated that PCPA and cystamine reduce lifespan longevity drastically and even in F1 offsprings from mothers with reduced level of serotonin. HTP incubation to the contary extended mean lifespan longevity up to 22 % even in F1 offsprings from mothers with extended levels of serotonin. Thus, our results demonstrated that serotonin impacts lifespan longevity and moreover the level of serotonin in mother organism affects offspring lifespan longevity.

Coordination of cellular biological processes is regulated in part via metabolic enzymes acting to match cellular metabolism to current conditions. The acetate activating enzyme, acyl-coenzyme A synthetase short-chain family member 2 (Acss2) has long been considered to have a predominantly lipogenic function. More recent evidence suggests that this enzyme has regulatory functions in addition to its role in providing acetyl-CoA for lipid synthesis. We used Acss2 knockout mice (Acss2-/-) to further investigate the roles this enzyme plays in three physiologically distinct organ systems that make extensive use of lipid synthesis and storage including the liver, brain and adipose tissue. We examined the resulting transcriptomic changes resulting from Acss2 deletion and assessed these changes in relation to fatty acid constitution. We find that loss of Acss2 leads to dysregulation of numerous canonical signaling pathways, upstream transcriptional regulatory molecules, cellular processes, and biological functions, which were distinct in the liver, brain and mesenteric adipose tissues. The detected organ-specific transcriptional regulatory patterns reflect the complementary functional roles of these organ systems within the context of systemic physiology. While alterations in transcriptional states were evident, the loss of Acss2 resulted in few changes in fatty acid constitution in all three organ systems. Overall, we demonstrate Acss2 loss institutes organ-specific transcriptional regulatory patterns reflecting the complementary functional roles of these organ systems. Collectively, these findings provide further confirmation that Acss2 regulates key transcription factors and pathways under well-fed, non-stressed conditions, and acts as a transcriptional regulatory enzyme.

Avocado is a fruit crop that is commercial and potential to be widely cultivated. Market demand for avocado was increased so production of avocado seed must increase too by grafting. The problem of grafting is often found in the connection between scion and rootstock that showed like elephant foot phenomenon, so it was necessary to study the linkage process between scion and rootstock. This research leads up to an increased percentage of finished graft seedlings that were ready for planting in the field. This method used a factorial experiment consisting of 2 factors. The first factor was the stages of entres (flushing, endodormancy, and ecodormancy), and the second factor was the grafting method (cleft graft, wedge graft, and splice graft). The research design used Complete Randomized Design with 4 replications and ANOVA with BNJ 5% test. The results showed all observations parameters interacted. Stage ecodormancy in splice graft resulted of vascular tissue (xylem and phloem) between scion and rootstock recovered better than other combination treatments by producing the best-grafted avocado seedlings growth with an increased percentage of grafted seedling by 42.50%, an interval of flushing by 4.91 days, and increased frequency of flushing by 1.83 times compared to stage flushing in cleft graft.
Symbol Error Probability Optimization of OFDM Bidirectional AF Relaying Systems
Authors: Qin Dong , Zhou Tianqing
Published: January 2023

This paper considers that two transceivers exchange orthogonal frequency division multiplexing (OFDM) signals with the aid of multiple bidirectional amplify and forward (AF) relays. Unlike most researchers who care about sum rate maximization issues to improve transmission efficiency, we formulate a symbol error probability (SEP) minimization problem under total power constraint because high data rate may degrade SEP performance. A joint algorithm of power allocation and relay selection is proposed to study their impact on the SEP performance. The closed-form solution of power allocation is not a form of water filling widely used in the sum rate maximum problem. Both analytical and simulation results clearly demonstrate the superiority of our algorithm.

Published: January 2023

In 2022, the coronavirus disease 2019 (COVID-19) continues to spread worldwide with the emergence of many variants. Healthcare workers (HCWs) are encouraged to be vaccinated against COVID-19 because vaccines provide powerful protection from serious illnesses, hospitalization, and death. However, breakthrough infections on vaccinees have been frequently reported, and more studies are required to understand the mechanism of breakthrough infection and establish a standard neutralizing antibody (NTAb) level with efficacy. In particular, it is important to develop useful research tools for HCWs at high risk of breakthrough infection. Here, we administered a brief questionnaire on awareness of COVID-19 vaccines and antibody tests to uncover the needs of HCWs. Our questionnaire showed that HCWs felt a lower priority for vaccines among infection control measures than non-HCWs. On the other hand, HCWs expected more strongly the vaccine to be effective in preventing infection at work than non-HCWs. About half of the respondents, whether HCWs or not, thought that there was a correlation between the severity of adverse reactions and the degree of antibody induction. About 20% of the respondents had a change in awareness of the correlation after an antibody survey. Many respondents believed that the antibody test would be useful. Therefore, we should contribute to the development of a method of evaluating vaccines that can protect against infection and to improving other infection control measures in the future.

Public health education to change the global health conversation
Authors: Galea Sandro
Published: January 2023

Population health is driven by the forces in the world around us. Those forces, in turn, are determined by a national and global conversation about priorities and values.This highlights the challenges public health faces to achieve its broader aspirations. The long-drawn national and global debates about what to prioritize and how collective resources should be invested are influenced, both positively and negatively, by a wide variety of factors. Political considerations about where resources should be deployed and who benefits from them and who does not, are a central part of any national or global conversation. Similarly, commercial stakeholders have a particular and legitimate interest in a broader conversational environment, given the impact this topic can have on their commercial viability. Additionally, broader public conversations depend on the millions of small-scale conversations at the proverbial kitchen table that, together, lead to change and form the national and global consensus. This essay establishes the need to catalize, on small and large scales, the underpinnings of public health on an ongoing basis.
