The main purpose of this research is to study the Leslie-Gower model and the response of the Holling type II with time delay and proportional harvesting. The method used in the completion of the model is qualitative, namely by analyzing the stability of the model's equilibrium point. The Leslie-Gower model and Holling type II response with delay time and proportional harvesting have four equilibrium points. There is one point of unstable equilibrium and one point of equilibrium that is stable. Meanwhile, for the other two equilibrium points, it depends on the value of the parameters taken. The delay time resulted in oscillations in the model. The greater the delay time value used, the greater the inequality in oscillations that occur in the system. This means the model will take longer to stabilize.

Modern trends in higher education are aimed at the fact that the educational process should become more dynamic and flexible, including the training of engineering specialists in higher educational institutions. During the pandemic caused by COVID-19, most institutions switched to distance learning, in connection with this, the use of virtual instruments created using the LabVIEW graphical programming environment is of particular relevance for practical and laboratory work. Such instruments allow you to conduct classes remotely. The article describes the designed virtual instrument for simulation modeling of the process of determining the surface roughness parameters. To implement this task, a model for calculating the surface roughness parameters is proposed, which takes into account the influence of the geometric parameters of the metal cutting tool and the physic of cutting process during workpiece processing. The modeling process of roughness measurement is carried out in two stages. At the first stage, the movement of the sensor of device the along the scanned surface and the sound of the device drive are simulated. At the second stage, the surface roughness parameters are calculated. The surface roughness profile is a superposition of the theoretical profile which is obtained by copying the profile of the cutting tool tip on the machined surface and random distortion of the profile due to the physic of cutting process. For the purpose of obtaining the coordinates of the theoretical profile points of the workpiece after processing it, an algorithm has been developed for calculating the current position of the profile point depending on the ratio of the feed values and the curvature radius tip of the cutting tool. Changing the position of the current point of the theoretical surface profile due to the impact of the physic of cutting process is taken into account by introducing random oscillations superimposed on the surface profile, which are generated by a random number generator according to the law of equal probability. A technique for processing an array of profile points coordinates to obtain surface roughness numerical parameters Rz, Ra and Rmax is described. The use of computer measuring technologies for solving tasks in the field of engineering using information and measuring equipment allows students to develop the skills to perform technical measurements, receive, analyze and critically evaluate the obtained measurement results

During development and design of information-measuring systems, enabling to carry out collection, processing and transmission of information, one of the main problems is the choice of effective methods of information protection against defects in noisy communication channels. Effective use of frequency-time resources of information communication channels, as the most valuable part of the information transmission system, is the key to provide reliable delivery of transmitted messages. One of effective directions of reliability increase and information transfer reliability in information-measuring communication networks is implementation of methods and algorithms of noise-resistant coding, providing for detection and coping with errors, arising due to interferences in the communication channel. In this case, the choice in favor of one or another coding method depends on the information characteristics of the data channel. Parameters of the noise coder must be coordinated with the source of the message, the communication channel, as well as the requirements for the reliability of bringing information to the recipient. The problem of obtaining a wide range of codec parameters with simultaneous preservation of the unified macrostructure of the codec in communication systems causes the need for research on the development of adaptive algorithms for error information protection. In the article the research results of the characteristics of variable rate slot convolutional codes for adaptive coding/decoding in information-measuring systems of information transmission are proposed. Consequently, when creating communication networks, there is no need to use a large number of different codecs, even with completely different requirements to the code rate, channel rate and gain due to coding. In addition, there is a real opportunity to create terminal equipment, working on unified algorithms of protection against errors and access.
Experimental Study on Physical Simulation of Large-Scale Interfracture Injection and Production with Different Injection Media in Tight Oil Reservoirs

Published: July 2022

Abstract
Given the difficulty of water injection and effective displacement system establishment in Changqing oilfield, this research carried out the interfracture injection and production experiment of a large outcrop model with two types of injection fluid medium, natural gas and surfactant, and studied the interfracture injection and production law of different displacing medium and the principal contradiction existing in the different displacing medium. The results show that natural gas drive in tight oil reservoir is beneficial to reduce the Jamin resistance and form a rapid oil production. Still, the gas drive process is easy to develop gas breakthrough, leading to a decrease in gas utilization ratio, and its oil displacement efficiency is 17.25%. Additionally, due to the strong adsorption of surfactant, the seepage capacity of a porous medium in the process of surfactant-oil displacement is reduced, and blockage is formed at the injection end, resulting in the poor oil displacement effect of surfactant. However, compared with natural gas injection, the surfactant has higher oil displacement efficiency, up to 22.05%. Therefore, for tight oil reservoirs, rational utilization of the advantages of different mediums and controlling their disadvantages are essential for the development of such reservoirs.
Fault Zones and Stress Fields in the Sedimentary Fill of Lake Baikal: Tectonophysical Approach for Seismic and Hydroacoustic Data Interpretation

Published: July 2022

Abstract
—This paper presents a schematic summary of comprehensive analysis of seismic, reflection profiling, and hydroacoustic data on faults which caused sediment deformation in the central segment of the Central Baikal basin. According to the tectonophysical analysis results, the fault pattern within sediment fill has been recognized as zone-block, i.e., it represents a network of high-density fracture zones limiting weakly deformed blocks. The structure of large NE-trending fault zones (Olkhon, Beregovoy, Gydratny, and Svyatoy Nos) is controlled by main fault planes (or their segments) bounded by subsidiary faults. Geomorphic expression of NW cross faults in the sedimentary cover as broad zones of smaller-scale fractures accounts for early stages of the evolution of basement faults. In a longitudinal direction, they divide the basin into large fragments. The zone–block structure of the sedimentary strata was developed in different stress regimes: strike-slip and extension at the early and late orogenic rifting stages, respectively. At the modern stage of tectogenesis, the established network of fault zones controls the gaseous (including hydrate formation) and seismic activity expression in the subsurface. Hydrate-bearing mud volcanoes and seeps are confined to major faults, while earthquake epicenters are confined to fault zones and form clusters at junctions of large NE-trending faults with NW-oriented extension zones and E–W left-lateral strike-slip faults.
Rare-Metal Li–F Granites in the Late Paleozoic, Early Mesozoic, and Late Mesozoic Magmatic Areas of Central Asia

Published: July 2022

Abstract
—In the Central Asian Orogenic Belt, Li–F granites formed in magmatic areas of different ages within a wide time interval, 321–134 Ma. The Li–F granites compose large multiphase plutons (Janchivlan and Baga-Gazriin Chuluu) and small intrusions, have specific mineralogic and geochemical characteristics, and show enrichment in Sn, W, Li, Rb, Ta, and Nb, thus forming concentrated mineralization at the late magmatic and postmagmatic stages. The late Paleozoic and Mesozoic small intrusions (Kharagul, Urugudei, Bezymyanka, Henteyn, and Turga) are high-alkali Li–F granites enriched in Zr, Nb, Hf, Th, U, and REE, which differ from ore-bearing Li–F granites in mineral assemblages and geochemical features. Such granites can be classified as an individual subtype of rare-metal granites. Irrespective of geochemical characteristics, the Li–F granites of the studied provinces in Central Asia are geochemically different from typical collision-related granites resulting from the melting of the upper continental crust. It is shown that the formation of rare-metal magmas with different geochemical characteristics is related to the mantle–crust interaction. The geochemical evolution of Li–F granites is significantly contributed to by the activity of mantle fluids containing trace elements and by the differentiation of granitic magma in the crustal intermediate chambers, which is favorable for the formation of associated rare-metal mineralization.

Published: July 2022

Abstract
Background & Aim: Fear of childbirth and pregnancy anxiety may affect the desire for normal delivery. No study has investigated the effectiveness of solution-focused counseling on either pregnancy anxiety or all factors comprising fear of childbirth. We aimed to investigate the effects of solution-focused counseling in reducing pregnancy anxiety and fear of childbirth.Methods and materials: This randomized clinical trial study was conducted on 121 nulliparous women in 2019. Participants with moderate to severe fear of childbirth were randomly divided into the intervention and control groups. The intervention group participated in five solution-focused counseling sessions. Before and after the intervention, women filled the anxiety scale for pregnancy (ASP) and the Wijma Delivery Expectancy Questionnaire (W-DEQ). Data were analysed using t-test, paired t-test, and analysis of covariance (ANCOVA).Results: The two groups did not differ in terms of demographic and obstetric variables and pregnancy anxiety pretest scores (P>0.05). The means of the posttest total scores and the means of scores for all five factors of the ASP were significantly lower in the intervention group than the control group (p<0.001). The adjusted means of total scores and the adjusted means of scores for all six factors of the WDE-Q were significantly lower in the intervention group than the control group (p<0.001).Conclusions: The solution-focused counseling reduced pregnancy anxiety and fear of childbirth in women participating in counseling sessions in comparison with the controls. Solution-focused counseling therapy sessions should be held for women with pregnancy anxiety and fear of childbirth.

Authors: Sakamoto Akio , Noguchi Takashi , Matsuda Shuichi 
Published: July 2022

Abstract
Objective Tenosynovial giant cell tumors (TSGCTs) are benign but aggressive lesions. Low to intermediate signal intensity on both T1- and T2-weighted images on magnetic resonance imaging (MRI) is characteristic, possibly reflecting hemosiderin deposition. T2-star (T2*)-weighted MR images reflect the paramagnetic deoxyhemoglobin, methemoglobin, or hemosiderin in the lesions and surrounding tissues. Materials and methods In 23 TSGCT patients (6 male and 17 females), the T2* MRI findings, the cystic changes confirmed on the T2-weighted image, potentially characteristic of TSGCT, were analyzed.Results The tumor locations included 10 large joints including nine knees and one ankle, 10 small joints including six fingers and four toes, and three wrists/hands. Ten diffuse and 13 localized tumors were predominantly located in the large joints and small joints, respectively. Cystic changes were seen in five (22%), predominantly in the large joints. The T2*-weighted images indicated three signal patterns of low, iso and high signal intensity compared to muscle. The low-, iso- and high-signal intensities were seen in 22 (96%), 23 (100%) and 12 (52%) of the locations, respectively. To distinguish TSGCTs from the surrounding tissue, the low intensity T2*-weighted images and low to intermediate intensity T1-weighted images when compared to muscle and fluid, respectively were useful for the large joints. Low to intermediate intensity on T1- or T2-weighted images was useful to distinguish TSGCTs from subcutaneous tissue in the small joints.Discussion MRI using T2*-, as well as T1 and T2-weighted images, is useful to assess the extent of TSGCTs within tissue, which is important for surgical planning.Institutional Review Board ApprovalThis report has been approved by the institutional review board of our institution (R2499).

Published: July 2022

Abstract
Background: Procedures and actions such as injections and immobilization cause distress to children. In the pediatric field, there is a need for interventions and support to alleviate the pain and distress caused by such medical procedures. In recent years, the introduction of robots as a means of distraction has begun to be attempted. Methods: In this study, we conducted a non-randomized controlled trial to examine the effect of intervention using ‘aibo’, a dog-like robot which has artificial intelligence (AI), to promote distraction in children after vaccination. Children between the ages of 3 and 12 years old eligible for the Japanese encephalitis vaccine, and their caregivers were assigned to intervention group or control group. Then, children evaluated their pain and children’s behavior were observed by observer. The mean values of Faces pain rating scale scores and observer pain scale scores were compared between groups using an unpaired t-test.Results: Fifty-seven children (32 in the intervention group) participated in the study. Results of a t-test with the control group showed that the intervention group using aibo had significantly less pain following the post-vaccination intervention than the control group using stuffed dog (Face Scale, t(55) = 2.582, p = .0125; Behavioral Observation Scale, t(55) = 2.772, p = .00759). The results support the hypothesis that the aibo intervention group will be less distressed and able to calm down more quickly after vaccination than the control group. Conclusion: Interactive communicative play intervention by an artificially intelligent aibo before and after painful and frightening medical procedures may alleviate fear and anxiety and prevent medical trauma in children.

Published: July 2022

Abstract
KDM6B (Lysine-specific demethylase 6B) is a histone lysine demethyltransferase that plays a key role in many types of cancers. However, its potential role in gastric cancer (GC) remains unclear. Here, we focused on the clinical significance and potential role of KDM6B in GC. We found that the KDM6B expression is upregulated in GC tissues and that its high expression in patients is related to poor prognosis. KDM6B ectopic expression promotes GC cells’ proliferation and metastasis, while its inhibition has opposite effects in vitro and in vivo. Mechanistically, KDM6B promotes GC cells proliferation and metastasis through its enzymatic activity through the induction of H3K27me3 demethylation near the CXCR4 (C-X-C chemokine receptor type 4) promoter region, resulting in the upregulation of CXCR4 expression. Furthermore, H. pylori was found to induce KDM6B expression. In conclusion, our results suggest that KDM6B is aberrantly expressed in GC and plays a key role in gastric carcinogenesis and metastasis through CXCR4 upregulation. Our work also suggests that KDM6B may be a potential oncogenic factor and a therapeutic target for GC.

Published: July 2022

Abstract
Pearl oyster shells comprise two layers, a prismatic and nacreous layer, of calcium carbonate. The nacreous layer has been used in Chinese medicine since ancient times. In this study, we investigated the effects of the extract from the nacreous layer of pearl oysters (nacre extract) on D-galactose-induced brain and skin aging. Treatment with nacre extract led to the recovery of D-galactose-induced memory impairment, as examined using the Barnes maze, novel object recognition, and Y-maze tests. A histological study showed that nacre extract suppressed D-galactose-induced neuronal cell death and the expression of B-cell lymphoma 2 (Bcl-2)-associated X protein (Bax), which causes apoptosis in the hippocampus. In addition, the expression levels of brain-derived neurotrophic factor, which counteracts age-related brain dysfunction, and nicotinamide adenine dinucleotide-dependent deacetylase (sirtuin 1), which delays aging and extends lifespan, increased after nacre extract treatment. Moreover, the nacre extract showed antiaging effects against D-galactose-induced skin aging; it suppressed D-galactose-induced wrinkle formation, decreased skin moisture, decreased epidermal thickness, and destroyed collagen arrangement associated with aging. Furthermore, the nacre extract suppressed oxidative stress associated with aging in the brain and skin by upregulating the expression of catalase and superoxide dismutase. The expression level of the cellular senescence marker p16, which is induced by oxidative stress, was elevated in the hippocampus and skin epidermal layer of D-galactose-treated mice, and it was suppressed by the administration of nacre extract. These results show that the nacre extract can suppress D-galactose-induced aging by enhancing antioxidant activity and suppressing p16 expression. Thus, the nacre extract may be an effective antiaging agent.
